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

Embodiment 1

[0062] Please refer to Figure 1-19 , the present embodiment discloses an elevator guide shoe wheel device, including a support frame 1, the support frame 1 includes a horizontally arranged top plate 11 and a bottom plate 12, and several vertical rods 13 are arranged between the top plate 11 and the bottom plate 12, The support frame 1 is fixedly installed on the top of the elevator;

[0063] Further, the guide shoe wheel 3 device also includes a vertical slideway 2 and several guide shoe wheels 3, all guide shoe wheels 3 are slidably matched with the vertical slideway 2, and several abutting mechanisms are arranged on the support frame 1 4. All guide shoe wheels 3 make themselves close to the vertical slideway 2 through the abutting mechanism 4 .

[0064] Further, the abutment mechanism 4 includes a vertical slide bar 41, and several horizontal guide bars 14 are fixedly installed on each vertical bar 13, and the vertical slide bar 41 is simultaneously guided with all horizon...

Embodiment 2

[0074] This embodiment discloses a method for using an elevator guide shoe wheel device, which includes the following steps:

[0075] Step S1: All the guide shoe wheels 3 are slidingly matched with the vertical slideway 2. After long-term use, the distance between the vertical slideway 2 and the guide shoe wheel 3 increases, and the push spring 42 pushes, and the vertical slide bar 41 moves toward the vertical slideway 2, while the limit helical tooth plate 43 and the helical tooth section 47 cooperate to prevent the vertical slide bar 41 from regressing, so that the guide shoe wheel 3 is always attached to the vertical slideway 2; the limit helical tooth plate 43 and the helical tooth section 47, so that the vertical slide bar 41 can only move towards the vertical slideway 2, and cannot retreat, while avoiding that the push spring 42 is compressed for a long time and loses its elastic restoring force, and cannot act on the vertical slideway 2. Situation on rod 41.

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...
