Description

Technical Field

[0001] The utility model relates to the technical field of elevator guide shoes, in particular to a shock-absorbing and noise-reducing elevator guide shoe. Background Technique

[0002] The guide shoe is a slidable nylon block between the elevator guide rail and the car, called the guide shoe. It can fix the car on the guide rail and allow the car to move only up and down. There is also an oil cup on the upper part of the guide shoe to reduce the friction between the shoe lining and the guide rail. Four sets of guide shoes are installed on each elevator car, respectively on both sides of the upper beam and under the safety tong seat at the bottom of the car; four sets of counterweight guide shoes are installed at the bottom and upper part of the counterweight beam and fixed on the car. The guide shoes fixed on the car can reciprocate up and down along the fixed guide rail installed on the wall of the building hoistway to prevent the car from tilting or swinging during operation.

[0003] The patent with the patent number CN203372956U in the prior art discloses a noise-reducing and shock-absorbing guide shoe, including a shoe body, a shock pad, a heat insulation board, a side plate one, a side plate two, and a bottom plate. The shoe body is in a "concave" shape and is composed of a side wall one, a side wall two, and a bottom wall formed integrally. The shock pads are respectively arranged on the side wall one, the side wall two, and the bottom wall. The heat insulation board is arranged on the shock pad. The side plate one and the side plate two are respectively arranged on the heat insulation boards of the side wall one and the side wall two. The bottom plate is arranged on the heat insulation board of the bottom wall. The utility model effectively reduces the vibration and noise generated by the friction between the guide shoe and the guide rail during elevator operation by setting shock pads and opening heat dissipation slots on the guide shoe, and can dissipate heat from the guide shoe to a certain extent, improve the use effect, and extend the service life.

[0004] However, there are the following several disadvantages in the prior art:

[0005] (1) The patent in the prior art is provided with shock pads, which can slow down the vibration generated when the elevator descends. However, the weight of the elevator is relatively large, and simply relying on one shock pad cannot achieve a good shock-absorbing effect. Moreover, when the elevator with a large weight is running, the shock pad is easily crushed and damaged by the pulley, and it is not convenient to replace.

[0006] (2) The elevator guide shoe in the prior art is a complete structure. When the guide wheel of the elevator is running, all the weight is borne by a single integral guide shoe and cannot share the pressure. After long-term use, it is easy to reduce the service life of the guide shoe. Content of the Utility Model
