Technical Field

[0001] The utility model relates to the technical field of elevator auxiliary equipment, in particular to a compensation chain guide device with adjustable spacing. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building. Its car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or have an inclination angle of less than 15 degrees to the plumb line. In order to compensate for the weight of the elevator wire rope and ensure smooth operation of the elevator, the elevator needs to be installed with a compensating chain. When in use, the compensating chain needs to be used with a compensating chain guide device. Existing compensating chain guide devices have some problems, such as poor buffering effect. The pulling and shaking generated during use can easily cause the guide device to wear, reducing the service life of the compensating chain guide device and being unfavorable for people's use.

[0003] For example, a Chinese patent with publication number CN216711305U discloses a compensation chain guide device with adjustable spacing, comprising a fixed box, a motor fixedly connected to the bottom of the inner cavity of the fixed box, threaded rods fixedly connected to both sides of the motor output end, telescopic rods sleeved on the surface of the threaded rods, the opposite sides of the two telescopic rods extending to the outside of the fixed box, buffer boxes provided on both sides of the top of the fixed box, a control panel sleeved on the surface of the buffer box, and a limit box provided on the top of the control panel. The utility model solves the problem that the existing compensation chain guide device has a poor buffering effect and is easily affected by pulling and shaking and causes wear by providing a control panel, a movable panel, a spring, a guide frame, a guide wheel, a control shell, a push plate, a push block, an elastic sheet, an adjustment plate, a rubber pad, a push rod, a friction block and an adjustment wheel. The compensation chain guide device has the advantages of good buffering effect and preventing the guide device from being affected by external forces and causing wear.

[0004] There are certain defects when using the above method. In daily use, elevators of different heights use compensation chains of different sizes. When the above method is used, the spacing between the two guide wheels is not easy to adjust, which limits the applicability of the guide device. The overall structure is complex, the production cost is high, and maintenance is difficult. Therefore, this application provides a compensation chain guide device with adjustable spacing to meet the needs. Utility Model Content
