Description

Technical Field

[0001] This utility model relates to the field of elevator guide shoe technology, specifically an elevator elastic sliding guide shoe. Background Technology

[0002] Elevators are slidably mounted on guide rails via guide shoes. Due to the high installation height of the elevator guide rails, the verticality of the guide rails may be somewhat skewed in the front-back or left-right directions. Existing guide shoes are generally held in place by springs. During sliding, the guide shoe lining will experience increased friction on one side due to the skew of the guide rails. Excessive friction may affect the normal operation of the elevator, and long-term wear will affect the service life of the elevator.

[0003] Existing patents disclose a multi-degree-of-freedom elevator elastic sliding guide shoe, patent number CN210214468U. The patent document describes that the guide shoe head rotates around the main axis to automatically adjust the guide shoe head. However, the guide shoe head is coaxial with the main axis. When a misalignment occurs, the guide shoe head will shift with the guide rail, causing the car to shift as well. If the guide shoe heads on both sides of the car shift synchronously in opposite directions with the guide rail, it will increase the risk of jamming the car and increase the friction between the guide shoe head and the guide rail. Therefore, the car cannot shift synchronously with the guide shoe head. To solve the above problems, this application provides an elevator elastic sliding guide shoe. Utility Model Content

[0004] The technical problem solved by this utility model is to provide an elevator elastic sliding guide shoe that can be adjusted on the base, so that the guide shoe liner can be adjusted with the guide rail without causing the car to move, thereby maintaining the stability of the car and solving the problems mentioned in the background art.

[0009] The swinging component includes a rotating column fixedly mounted on the back of the boot platform and a swinging plate rotatably mounted on the rotating column. The side of the swinging plate away from the rotating column is rotatably connected to the spring-loaded component.

[0010] As a further embodiment of this utility model:

[0011] The spring-loaded component includes a pressure shaft rotatably connected to the swing plate and a sleeve fixedly mounted on the base frame. The outer side of the pressure shaft is integrally provided with a threaded part, which passes through the sleeve and is threadedly connected to a nut so that the nut abuts against the outer end of the sleeve. The pressure shaft is also provided with a pressure plate, and a spring is sleeved on the outer end of the pressure shaft located on the pressure plate. One side of the spring abuts against the pressure plate, and the other side abuts against the outer wall of the sleeve so as to push the pressure shaft to move toward the shoe platform side, so that the shoe platform is attached to the guide rail.

[0012] As a further embodiment of this utility model:

[0013] The boot platform has a U-shaped structure, and the boot liner is built into and fitted into the U-shaped groove of the boot platform. The boot liner also has a U-shaped structure so as to be sleeved on the outside of the guide rail. The back of the boot liner has a protrusion, and the inner side of the boot platform has a corresponding block groove to allow the protrusion to be inserted into the block groove.

The locking block is inserted into the locking groove to fix the boot liner on the boot platform. The clamping plate is provided with a corresponding U-shaped groove corresponding to the boot liner so that the guide rail can pass through.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: the boot liner is snapped onto the boot platform, and the elastic component drives the boot platform to move outward along the guide rail to adhere to it. The two sides of the boot platform are elastically connected to the elastic pads on the base frame, and the back of the boot platform is connected to the pressure shaft via a swing plate. The boot platform can tilt and swing left and right within the base frame, allowing the boot liner to shift position with the guide rail, avoiding excessive friction on one side of the boot liner. This device allows the boot platform to be properly positioned within the base frame without affecting the vertical movement of the car, ensuring that the guide shoes distributed around the car complement each other. The elastic pads on both sides of the base frame elastically clamp the boot platform, limiting its free swinging and helping it to return to its original position, thus improving the stability of the boot platform within the base frame.
