Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an elevator with an elevator balance compensation chain protection device. Background Art

[0002] The structure of the compensation chain is an iron chain wrapped with PVC rubber composite material. It is used to compensate the weight of the wire rope to make the elevator run smoothly. When the elevator is on the top floor, the wire rope is on the counterweight side, and the counterweight side has more weight of the wire rope. When the elevator is on the bottom floor, the wire rope is on the car side, and the car side has more weight of the wire rope. The installation of the compensation chain can balance this part of the drop. It is used to compensate for dynamic balance. Because the wire rope has weight, as the elevator moves up and down continuously, dynamic imbalance will occur, so the compensation chain is used. It is one of the important components of the elevator.

[0003] The patent specification with announcement number CN220564060U discloses an elevator with a compensation chain protection device, including an elevator room and a compensation protection mechanism, wherein a car ladder is arranged inside the elevator room. The utility model realizes load balance by setting a compensation protection mechanism and a compensation chain, wherein the compensation chain connects the car ladder and the counterweight block, and a pulley system is used to balance the load. When the elevator is working normally, the compensation chain ensures the force balance between the car ladder and the counterweight block by adjusting the length, so that the elevator remains on the running track and provides stable vertical movement. When the car ladder goes up, the length of the compensation chain will be extended on one side of the car ladder, so that the counterweight block moves downward, and the car ladder can rise. On the contrary, when the car ladder goes down, the length of the compensation chain will be extended toward the side of the counterweight block, so that the car ladder can descend. Through the restriction of the compensation chain, the elevator can be made more stable during operation, and the compensation chain can share the weight of the elevator at a low level, so that the car and the counterweight block are evenly stressed.

[0004] However, in the implementation of relevant technologies, it was found that the elevator with a compensating chain protection device of the above design has the following problems: in the prior art, the stability of the elevator is improved during operation through the cooperation of components such as counterweights, but the compensating chain slides against the fixed platform during the sliding process, and there is no corresponding protection device, which leads to easy deviation during the sliding process or wear over time, thereby affecting safety. In view of this, an elevator with an elevator balance compensating chain protection device is provided to overcome the above defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes an elevator with an elevator balance compensation chain protection device.

[0009] As a further description of the above technical solution: sliders are fixed on both sides of the outside of the mounting plate, and sliding grooves are opened on the inner wall of the storage shell at the positions of the sliders. Through the cooperation of the sliders and the sliding grooves, the mounting plate is prevented from driving the second conveying wheel to deviate or shake under the influence of the compensation chain body.

[0010] As a further description of the above technical solution: a conveying pipe is passed through the interior of the storage shell, and one end of the conveying pipe passing through the ladder shaft is connected to a feeding pipe. The feeding pipe is connected to an external feeding device to introduce lubricating oil, and the conveying pipe conveys the lubricating oil to the interior of the two storage shells. The lubricating oil is applied through the rotational conflict of the second conveying wheel and the compensation chain body, thereby achieving a lubricating effect, avoiding excessive friction and wear, and achieving a protective effect.

[0011] As a further description of the above technical solution: a limiting mechanism is arranged above the fixed platform, and the limiting mechanism includes a limiting plate, and the limiting plate is fixed to the top of the fixed platform, and mounting grooves are provided on both sides of the inner part of the limiting plate, and a second damping spring is embedded in the inner wall of the mounting groove, and one end of the second damping spring is connected to a fixed block, and a pressing plate is embedded in the outer wall of the fixed block away from the second damping spring, and the compensation chain body is limited by the limiting plate to avoid shaking during the working process that affects the stability of the elevator body.

[0012] As a further description of the above technical solution: the structure of the limit plate is a U-shaped structure, and the limit plate is elastically connected to the fixed block through a second damping spring.

The pressing plate with an arc structure can play a certain limiting effect to avoid shaking of the compensation chain body.

[0014] The utility model has the following beneficial effects:
