Description

Technical Field

[0001] The utility model relates to the field of home decoration elevators, and particularly relates to a traction-driven automatic side-opening steel belt platform elevator. Background Art

[0002] With the increasing improvement of people's living standards, villa elevators have entered thousands of households. Considering the space limitations of villa buildings, especially in existing house buildings, it is difficult to find a suitable place to install an elevator. Most people will consider installing an elevator in the middle of a spiral staircase, so that the original space of the house will not be occupied. However, due to space limitations, it is largely impossible to install an ordinary traction-driven automatic center-opening door elevator in the traditional sense.

[0003] In addition, the screw-type platform elevator in home decoration elevators has disadvantages such as slow running speed, large noise, obvious jitter, and high manufacturing cost; when the hydraulic pump of the hydraulic-driven elevator works, the noise is relatively large, the oil cylinders and oil pipe seals are prone to oil leakage, polluting the environment, the pump station occupies space, the temperature of the hydraulic oil is easy to rise, and it is more likely to leak oil and age the seals, resulting in a relatively high failure rate.

[0004] Therefore, the utility model provides a traction-driven automatic side-opening steel belt platform elevator to solve the above problems. Summary of the Utility Model

The elevator hoistway is composed of hoistway columns and hoistway crossbeams connected between the hoistway columns. An elevator door is arranged in front of the elevator hoistway, and the elevator door is a side-opening door that opens outwards; a counterweight and a backpack frame are installed in the rear hoistway, and both the counterweight and the backpack frame move up and down relative to the rear hoistway. The backpack frame is connected to drive a platform arranged at the bottom of the car, so that the car moves up and down in the elevator hoistway. A traction rope is lowered from the top of the rear hoistway, and one end of the traction rope is connected to the backpack frame and the other end is connected to the counterweight.

[0007] As a further technical solution, the hoistway crossbeams are arranged between the hoistway columns on the left and right sides of the elevator hoistway, so that a space for installing the elevator door is left in front of the elevator hoistway.

[0008] As a further technical solution, the elevator door includes an elevator door frame fixed to a derrick column, the elevator door frame is rotatably connected to a door leaf via a main shaft, and the door leaf is driven to rotate via the main shaft to realize the opening and closing of the elevator door.

[0009] As a further technical solution, backpack frame guide rails are fixedly installed on both sides of the inner wall of the rear well frame. The backpack frame adopts a "匚"-shaped structure. Guide seats are provided on both sides of the "匚"-shaped structure for sliding installation on the backpack frame guide rails.

[0010] As a further technical solution, a counterweight guide rail is further provided on the inner wall of the rear derrick for slidingly installing the counterweight, and the backpack frame is semi-enclosed outside the counterweight.

[0011] As a further technical solution, a buffer block is installed on the backpack frame next to the guide seat, and two rubber wheels are provided on the buffer block to reduce the vibration when the elevator is running.

[0012] As a further technical solution, the backpack frame also includes a traction rope mounting beam for connecting the traction rope. Beam mounting grooves are provided on both sides of the "匚"-shaped structure. The traction rope mounting beam is placed horizontally in the middle of the backpack frame, and beam fixing blocks are inserted at both ends. Screw holes are provided at both ends of the beam fixing blocks. After the screw holes are aligned with the beam mounting grooves, screws are inserted to fix the traction rope mounting beam.

[0013] As a further technical solution, the bottom of the backpack frame is connected and fixed to the platform via a platform connecting frame.

[0014] The beneficial effects of the utility model are:

[0015] 1. The design of traction drive and platform car occupies a small area, and the minimum installation size only takes up about 1 square meter of floor space. The overall structure is simple, the architecture is clear, the space utilization rate is high, and the pit requirements are low.

[0016] 2. The backpack rack is equipped with a buffer block to reduce the vibration of the elevator during operation, thereby reducing the noise problem in disguise.

The traction rope mounting beam is placed horizontally in the middle of the backpack frame, and beam fixing blocks are inserted at both ends. Screw holes are provided at both ends of the beam fixing hole. The screw holes are aligned with the beam mounting grooves, and screws are inserted to fix the traction rope mounting beam. The traction rope is connected to the traction rope mounting beam. When in use, the design of the traction drive and platform car occupies a small area. The minimum installation size only occupies an area of ​​about 1 square meter. The overall structure is simple, the architecture is clear, the space utilization rate is high, and the pit requirements are low. The backpack frame is equipped with a buffer block to reduce the vibration of the elevator during operation, which in disguise reduces the noise problem. The swing door design focuses on silence, and the noise generated during operation is extremely low. When opened, it can be fully opened outwards to facilitate passengers to enter and exit.
