Embodiment 1

[0032] Such as figure 1 As shown, an elevator guide wheel device in this embodiment includes a guide shoe wheel 10 and an elevator guide rail 20, and a support device 11 is provided on the guide shoe wheel 10; The guide shoe wheel 10 is supported when the wheel 10 is at rest, so that the guide shoe wheel reduces the pressure from the guide rail; the support device 11 is arranged on the wheel hub 12 .

[0033] The elevator guide rail is provided with a bearing device 21; the bearing device 21 is used to abut against the support device 11 of the guide shoe wheel 10 when the guide shoe wheel is at rest, so as to unload the stress of the guide shoe wheel. In this embodiment, the carrying device 21 is a load-relieving block. The shape of the load-relieving block is adapted to the supporting device 11 .

[0034] Owing to having adopted supporting device 11 and carrying device 21, when elevator was in the base (normally the first floor) position, the guide shoe wheel position bondi...

Embodiment 2

[0049] Such as image 3 As shown, an elevator guide wheel device in this embodiment includes a guide shoe wheel 10 and an elevator guide rail 20, and a support device 11 is provided on the guide shoe wheel 10; The guide shoe wheel 10 is supported when the wheel 10 is at rest, so that the guide shoe wheel reduces the pressure from the guide rail; the support device 11 is arranged on the wheel hub 12 .

[0050] The elevator guide rail is provided with a bearing device 21; the bearing device 21 is used to abut against the support device 11 of the guide shoe wheel 10 when the guide shoe wheel is at rest, so as to unload the stress of the guide shoe wheel. In this embodiment, the carrying device 21 is a load-relieving block. The shape of the load-relieving block is adapted to the supporting device 11 .

[0051] In this embodiment, the supporting device 11 is arranged on one axial side of the annular outer end surface of the hub 12 . This makes product design and installation eas...

Embodiment 3

[0054] On the basis of Embodiment 1 or Embodiment 2, this embodiment discloses an elevator, which adopts the guide shoe wheel device of Embodiment 1 or Embodiment 2, and the guide shoe wheel device is arranged in the backpack type elevator car The upper and lower parts of the shelf. There can be 3 or 6 guide shoe wheels in the present embodiment.

[0055] At the position of the base layer of the elevator (usually the first floor), the unloading block is bonded to the guide rail at the position of the guide shoe wheel. When the elevator runs to the base layer, the unloading block lifts up the rigid guide shoe hub to unload the force of the polyurethane layer. When the elevator runs again, after running out of the position of the unloading block, the polyurethane layer is under pressure. That is to say, when the elevator is parked for a long time, since the polyurethane layer is unloaded and stressed, there will be no crushing. When the elevator runs again, the polyurethane ro...

Abstract

The invention discloses an elevator guide shoe wheel device. The elevator guide shoe wheel device comprises a guide shoe wheel and an elevator guide rail, wherein a supporting device is arranged on the guide shoe wheel and used for supporting the guide shoe wheel when the guide shoe wheel is at a static position so that the guide shoe wheel can reduce stress from the guide rail; a bearing device is arranged on the elevator guide rail and used for abutting against the supporting device of the guide shoe wheel when the guide shoe wheel is at the static position so as to unload stress of the guide shoe wheel. The elastic recovery performance of the elevator guide shoe wheel is effectively improved, the defects that an elevator bumps, abnormal sounds are generated, and a roller blocks the guide rail are overcome, and the comfort and safety of elevator taking personnel can be fully guaranteed.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an elevator guide shoe wheel device. The invention also relates to an elevator using the guide shoe wheel. 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 along the fixed guide rail installed on the well wall of the building to prevent the car from deflecting or swinging during movement. In order to meet the high load-bearing requirements of the elevator during the lifting process, the TDI (toluene diisocyanate) polyurethane material with high hardness, high modulus and low flexibility is usually used to produce the elevator guide shoe wheel. The size of the roller is generally large. The outer diameter is about 100-130mm, and the width is about 35-40mm; when the elevator is in a static state for a long time, the guide shoe wheel is subject to static pressure for a long time, resulting in ...
