Elevator guide shoe wheel device

Abstract

The invention relates to the technical field of elevators, in particular to an elevator guide shoe wheel device which further comprises a vertical sliding way and a plurality of guide shoe wheels, all the guide shoe wheels are in sliding fit with the vertical sliding way, and a plurality of abutting mechanisms are arranged on a supporting frame. The abutting mechanism comprises vertical sliding rods, a plurality of horizontal guide rods are fixedly installed on each vertical rod, the vertical sliding rods are in sliding fit with all the horizontal guide rods on the single vertical rod at the same time, plugs are arranged at the ends, away from the vertical rods, of the guide rods, and the portions, located between the plugs and the vertical sliding rods, of the guide rods are sleeved with pushing springs. Bolts penetrating through the vertical sliding rods are arranged at the two ends of the vertical sliding rods, and reset springs are arranged on the bolts in a sleeving manner. The distance between the vertical sliding way and the guide shoe wheel is increased, a pushing spring pushes the vertical sliding rod to move towards the vertical sliding way, meanwhile, a limiting oblique tooth plate and an oblique tooth cutting section are matched to prevent the vertical sliding rod from retreating, and the guide shoe wheel is always attached to the vertical slide way to avoid shaking and abnormal sound.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator guide shoe wheel device. Background technique [0002] As an important part of the villa ladder, the elevator guide shoe wheel is fixed on the car and can move up and down reciprocatingly along the fixed guide rail installed on the well wall of the building to prevent the car from deflecting or swinging during the movement. Some guide shoe wheels have the following disadvantages: [0003] (1) When the elevator is in a static state for a long time, the guide shoe wheels are subject to static pressure for a long time, resulting in compression deformation. When the elevator restarts, the wheels cannot return to their original shape in a short time, causing the elevator to bump and affect safety. [0004] (2) When the elevator fails, there will be a rapid descent, which poses a great threat to the safety of the people in the elevator; and the existing processing method...

AI Technical Summary

Problems solved by technology

[0003] (1) When the elevator is in a static state for a long time, the guide shoe wheels are compressed and deformed by static pressure for a long time. When the elevator is restarted, the wheels cannot return to their original shape in a short time, causing the elevator to bump and affect safety.

[0004] (2) When the elevator fails, there will be a rapid descent, which poses a great threat to the safety of the people in the elevator; and the existing processing methods generally prevent the elevator from descending by appearing obstacles directly below the elevator, but if The elevator descends too fast, and the effect of this blocking method is not ideal;

[0005] (3) After the elevator has been used for a long time, the guide wheels and guide shoes have been severely worn and worn for a long time, resulting in shaking and abnormal noise when the elevator goes up and down. The abnormal noise will cause uneasiness to the people in the elevator;

[0006] (4) The existing guide shoe wheels are all hub frames, and then the outer side of the hub frame is provided with a soft rubber layer to reduce vibration, but after long-term use, after the soft rubber layer is worn off, bumps or abnormal noises will appear Case
