Electric tools and equipment commonly used in integrated wiring construction.

There are many construction tools for the integrated wiring pipeline system. The following are some commonly used power tools and equipment, only the names of simple electricians and hardware tools are listed.

1, electrician toolbox The electrician toolbox is an indispensable tool in wiring construction, which generally includes the following tools: wire cutters, needle-nosed pliers, oblique-nosed pliers, wire strippers, screwdrivers, cross screwdrivers, measuring pens, electrician knives, electrician tapes, adjustable wrench, dummy wrenches, tape measures, hammers, chisels, miters, steel files, hacksaws, etc.

Small materials such as cement nails, wood screws, self-tapping screws, plastic expansion pipes and metal expansion bolts should also be put in the toolbox. See Figure 3-39.

2. In the construction site, especially in the outdoor construction site, because of the wide construction scope, it is impossible to have electricity everywhere. Therefore, it is necessary to use long-distance power cord reel to connect electricity, with the length of 20 meters, 30 meters, 50 meters and other models. See Figure 3-40.

3. Hardware tools (1) Slot cutter The slot cutter is a special cutter for PVC slots, with neat and beautiful cut. See figure 3-4 1.

(2) The vice vice is one of the commonly used clamping tools for sawing, chiseling and filing small and medium-sized workpieces.

When the handle is shaken clockwise, the jaw will clamp the workpiece (such as steel pipe); Shake the handle counterclockwise and the workpiece will be released, as shown in Figure 3-42. When cutting angle steel with I-shaped cross arm, you can clamp the angle steel with vice. When sawing, hydrogen should hold the right hand of the saw bow hard, and the pressure on the left hand should not be too great (mainly straightening the saw frame). There are two kinds of reciprocating motion in sawing: linear reciprocating motion and oscillating motion. Generally, the body is lifted slightly and returned to its original position. But no matter what posture, in the process of sawing, we should always keep the sawing seam straight. Thick workpieces (such as round steel and I-beams) usually use remote saws. The sawing angle should not exceed 15? . Too big, sawing is not easy and smooth; Too small to cut into the workpiece. For thin workpieces (such as sheet steel and insulation board), it is recommended to start sawing from nearby. The sawing angle should not exceed 15? . When lifting the saw, thumb nails can be used to guide the saw blade in order to ensure the accuracy of the tangent point. When sawing metal bars, flat steel, angle steel and channel steel, we should start sawing from the thick surface as far as possible to increase the effective length of the saw blade and avoid the sawtooth being hooked and broken.

(3) When the ladder is installed, there is a pipe groove, so it is often necessary to climb high in the process of wiring and pulling. There are two kinds of commonly used ladders: straight ladder and herringbone ladder. Straight ladders are mostly used for outdoor climbing operations, such as installing outdoor optical cables on telephone poles and walls; The latter is usually used for indoor climbing operations, such as installing ducts and wiring cables. Before using the straight ladder and the inclined ladder, it is best to tie the foot of the ladder with rubber and other non-slip materials, and the inclined ladder should also be tied with a safety rope to prevent it from automatically sliding between two pages.

(4) Pipe vise The pipe vise, also known as gantry pliers, is a clamping tool for cutting tubular materials such as steel pipes and PVC plastic pipes. Its appearance is shown in Figure 3-43. The vise seat of the pipe vise is fixed on the tripod iron plate workbench. Open the tongs and pull the gantry to the right, and the pipe can be put into the jaws. Then straighten the frame, and the fixture will automatically fall and be fixed. Turn the handle to firmly clamp the pipe.

(5) In the construction of steel pipe wiring, the pipe cutter needs to cut a large number of steel pipes and electric conduits.

This is when the pipe cutter comes in handy. Pipe cutter is also called pipe cutter. As shown in Figure 3-44, it is a portable pipe cutter. When cutting the steel pipe, first fix the steel pipe on the pipe wrench, and then adjust the blade of the pipe cutter to make it just stuck in the position to be cut. The operator stands at the right front of the tripod iron plate workbench, operates the handle of the pipe cutter by hand, rotates clockwise once, and rotates the handle of the pipe cutter to make the blade cut off part of the pipe wall, so that the steel pipe can be cut off with a brush. When it is about to be cut off, you must hold the part to be cut off by hand to prevent the broken pipe from hitting your toes when it falls to the ground. The operation method is shown in Figure 3-45.

(6) The pipe wrench is shown in Figure 3-46, also known as the pipe wrench. Pipe wrench is a tool for installing steel pipe wiring, which is used for loading and unloading pipe hoop, lock nut, pipe joint, explosion-proof joint, etc. On the wire and pipe.

Commonly used pipe wrenches have various specifications such as 200mm\250mm and 350mm. (7) Thread hinge plate Thread hinge plate is also called pipe thread hinge plate. Hinge plate? . Common models are GJB-60 and WGJB- 1 14W. Its structure is shown in Figure 3- 1. Thread reaming disc is a hand tool for reaming the external thread of steel pipe, and it is one of the important pipeline tools. What are the functions of pipe cutter and pipe tongs in steel pipe wiring? Taoyuan sworn? Three brothers.

(8) Simple pipe bender This pipe bender is simple and easy to make. It is very common in some construction sites, and it is self-made and very dexterous.

Usually used for bends below 25mm. As shown in figure 3-48.

(9) Wire tubes with a slightly larger diameter (more than 25mm) or thick-walled steel tubes with a diameter less than 25mm can be bent by the pipe bender shown in Figure 3-49. It can also be made by itself.

4. Power tools

(1) Charging screwdriver (as shown in Figure 3-50) is a kind of electric tool that is often used in engineering installation. It can be used as both a screwdriver and an electric drill, especially a rechargeable battery, and can work without wires. One-handed operation, with positive and negative quick change buttons, flexible and convenient to use; Powerful torque, with all kinds of universal hexagonal tool heads, detachable and locking screws, drilling holes, etc. Instead of the traditional screwdriver, it is completely effortless to remove the locking screw, and it is not necessary for the locking screw to break the skin and blister, which greatly improves the work efficiency.

(2) Hand electric drill Hand electric drill (as shown in Figure 3-5 1) can be used to drill holes on both metal profiles and wood and plastic, and it is a common tool in the installation of wiring system. Hand drill consists of motor, power switch, cable and drill bit. Use the drill key to open the drill lock so that the drill chuck can be opened or tightened and the drill bit can be loosened or tightened.

(3) impact electric drill impact electric drill is referred to as impact drill. It is a special portable electric tool with rotary impact function. When it is necessary to drill holes in building materials such as concrete, prefabricated panels, ceramic tiles, brick walls, etc., just put? Hammer drill adjustment switch? Pull to the position marked with the hammer, and install the electric hammer bit on the bit? Also known as cemented carbide drill? Memos can produce the effects of rotation and impact, and drill holes in the required parts; When it is necessary to drill holes in malleable materials such as metal, just put? Hammer drill adjustment switch? Pull it to the position marked with a drill bit, and it will produce pure rotation. Replace it with an ordinary twist drill and drill like a hand drill. Its shape is shown in Figure 3-52. The impact drill has double insulation, which is safe and reliable. It consists of a motor, a gearbox, an impact head, an auxiliary handle, a switch, a power cord, a plug and a drill clamp.

(4) The electric hammer is powered by a single-phase series motor, which is suitable for drilling, slotting and gouging on brittle materials such as concrete, rock and masonry. Electric hammer has fast drilling speed and high hole-forming accuracy, which is similar to impact electric drill in function, but there are many differences in appearance and structure, as shown in Figure 3-53.

(5) electric pick as shown in figure 3-54. The electric pick adopts the mechanical structure of precision heavy electric hammer, which has powerful concrete shoveling function, more power than electric hammer, and stronger impact force and vibration force. Shock absorption control makes the operation safer, and the impact energy in production efficiency is adjustable, which is suitable for construction under various material conditions.

(6) Nail shooter Nail shooter, also known as nail shooter, uses the nail shooter to shoot nail bullets, so that the gunpowder in the bullets burns to release the driving force, and directly nails the special nails into the steel plate, concrete, brick wall or rock matrix, thus permanently or temporarily fixing the steel plate clips, plastic clips, PVC trough plates, steel or plastic calendar wall cabinets or junction boxes that need to be fixed. As shown in Figure 3-55, it is the fastening schematic diagram of the nail shooter. In operation, nails and nail-shooting bullets are loaded into the nail-shooting device, aiming at the fastener and the base, releasing the safety, holding the trigger, firing the nails, and the gunpowder gas pushes the nails through the fastener and into the base, thus achieving the purpose of fixation.

(7) As shown in Figure 3-56, the curve saw is mainly used to saw straight lines and special curve cuts in site construction; Able to saw wood, PVC and metal; The puzzle has the advantages of light weight, reduced fatigue, compact design and easy operation in a compact space; Adjustable speed, low-speed start, easy cutting control, shock-proof handle, easy to hold.

(8) As shown in Figure 3-57, the angle grinder will leave serrated burrs when cutting metal grooves and pipes, which will pierce the cable sheath. Use an angle grinder to smooth the cut opening to protect the cable. Angle grinder can also be used as cutting machine.

(9) When installing wiring conduit, profile cutting machine often needs to process angle iron cross arm and cut pipeline. The cutting speed and labor-saving degree of profile cutting machine are incomparable with hacksaw. Profile cutting machine as shown in figure 3-58. It consists of a grinding wheel saw blade, a protective cover, a control handle, a motor, a workpiece fixture, a workpiece fixture adjusting handwheel, a base, a rubber tire and the like. The motor is usually a three-phase AC motor.
