Elevator installation is very important. Matters needing attention in elevator installation

The elevator should be familiar to everyone. Elevator is a kind of vertical elevator powered by motor and equipped with box pod, which is used to transport people or goods in multi-storey buildings. There is also a step, the pedal is installed on the track and runs continuously, commonly known as escalator or moving sidewalk. Then do you know the precautions for elevator installation? Let's take a look together.

Precautions for elevator installation:

1. Location and spacing of hoistways: The location and spacing of hoistways determine the size of elevators and door openings. It is a good plan to install an elevator in the middle of the stairs and combine it with the stairs.

1 Stairs can be installed in the middle, corner or outdoors, preferably in the middle, and don't block the passage.

2. Back calculate the width of the shaft with the width of the door and the height of the car with the height of the top floor.

3. It is suggested that the load should be 3-4 persons, 225-320 kg, and the inside size of the car should be 0.8-1.0m2.. The relative load capacity of this area can be greater than that of the passenger elevator to increase the comfort.

Second, the determination of style: mainly consider the well environment and personal preferences, followed by cost and difficulty.

1 The closed shaft is equipped with a closed car, and the sightseeing shaft is equipped with sightseeing bus, which can be used for sightseeing on three sides or partially. It is recommended to install glass windows on the doors.

Cars come in various shapes. Rectangular, circular and combined doors are acceptable, and it is recommended to adopt transparent automatic folding doors.

Because there are many elevator parts, it is not easy to use fully transparent glass for family sightseeing ladders.

Third, the function and safety measures of domestic elevators. Users of domestic elevators lack elevator professional knowledge and specialized elevator service personnel, so the safety cannot be reduced. It is best to configure according to the standard of passenger elevator.

1 There are generally two ways to open the door. Automatic doors and manual doors. Automatic doors and manual doors must have electromechanical interlocking function to prevent landing doors from being opened when the elevator is unavailable.

There are elevators in China, but there are no hoistways abroad, and there are no doors on the second floor. But there must be safety measures to prevent shear collision.

3. Some villa elevators are designed with manual horizontal doors. This car has no door. Then a light curtain door must be installed to ensure that the risk of friction, collision and squeezing is prevented.

It is suggested that the car be connected with a local telephone extension to prevent people from calling for help when they are in trouble.

4. Plane layout and shape of the car: In order to save area, it is necessary to make a reasonable layout, and compare the layout with the plan of double automatic doors being offset and counterweight being placed side by side. The hoistway width 1200mm corresponds to the car width of 850mm and the door opening width of 700mm.

1 is the first choice for installing domestic elevators in the hollow space of U-shaped stairs. Steel structure shaft, light transmission design.

If it is a circular staircase with a circular elevator, it will be more beautiful.

There are two kinds, one is an ordinary semi-circular car with a flat automatic door, and the other is a circular car with a circular automatic door. 5. Bottom pit and top floor; The pit is used to install the buffer and accommodate the car bottom, and the top floor should be equipped with a traction machine. In some buildings, the pit can't be dug and the height of the top floor is small, so the domestic elevators must be designed flexibly according to local conditions.

1 Generally, the pit is 150 mm, and the bottomless pit can be used to decorate the ground, and then the elevator will be raised by another step, about 70 ~100 mm.

2 the height of the top floor is > 2438mm, and the height of the car is 2032 mm

6. Drive and control system: At present, the drive modes on the market are sprocket drive, hydraulic drive, traction drive, gearless drive and screw drive. Gearless transmission and sprocket transmission are adopted.

1 sprocket drive: Advantages: low product cost, low power consumption, small occupied space, no need for machine room, minimum pit of only 150mm, maximum speed of 0.3 m/s, full mechanical movement. Disadvantages: below 60 points will produce noise.

2. Hydraulic drive: Advantages: low power consumption, low pit requirements, maximum speed of 0.3m/s, and no noise during operation. Disadvantages: high product cost. There are requirements for outdoor temperature. And we must choose well-known manufacturers, otherwise the later maintenance cost will be high, and a small computer room of about 1m3 will be needed.

Seven, crowd safety: door failures account for a large proportion of elevator failures. Once the door protection fails or fails, the consequences are very serious, especially for villa ladders without doors.

Eight, the speed is appropriate: because the family floor is not high, there are old people and people with mobility difficulties to use. Speed is not easy, too fast. 0.25m/s on the second floor and 0.3 ~ 0.5m/s on the third floor.

Nine, internal and external decoration: the elevator at home must pay attention to decoration. The focus of decoration is not luxury, but the combination of home improvement style. Simple and practical to increase the highlights of home life, wooden cars, sightseeing bus, stainless steel cars, ceiling lamps, mirror headlights, energy-saving lamps and so on. External finishes, bricks and marble can be used.

Summary: The above are the precautions for elevator installation, and I hope it will be helpful to everyone.
