Guide shoe structure of inclined elevator car

Abstract

A guide shoe structure of an inclined elevator car comprises a guide shoe body. The left main wheel is arranged at the left end of the guide shoe body; the right main wheel is arranged at the right end of the guide shoe body; the lower limiting wheel is arranged at the bottom of the left end of the guide shoe body; the guide shoe is characterized in that the guide shoe further comprises a left safety wheel and a right safety wheel, the left safety wheel and the right safety wheel are arranged on the guide shoe body, gaps are kept between the left safety wheel and the surface of the upward side of the guide rail and between the right safety wheel and the surface of the upward side of the guide rail, and when the left main wheel is damaged and the rolling pair relation between the left main wheel and the guide rail disappears, the gap between the left safety wheel and the guide rail disappears. The left safety wheel and the surface of the upward side of the guide rail form a rolling pair; when the right main wheel is damaged and the rolling pair relation between the right main wheel and the guide rail disappears, the gap between the right safety wheel and the guide rail disappears, and the right safety wheel and the surface of the upward side of the guide rail form a rolling pair. Operation of the elevator car is guaranteed, and safety is ensured; the connection effect and reliability are ensured; and the rolling matching effect of the left and right main wheels and the guide rail is ensured.

Description

technical field [0001] The invention belongs to the technical field of elevator components, and in particular relates to a guide shoe structure for an inclined elevator car. Background technique [0002] The aforementioned inclined elevators are mostly used in light rail, subways, ports, scenic spots, hillsides and special buildings (including installation of old buildings), etc., and its working principle is to make the elevator car It runs along the inclined track with the counterweight to achieve the purpose of transporting (transporting) people and / or goods. [0003] As known in the industry, the elevator car is fixed with the elevator guide shoes, and the elevator guide shoes are matched with the elevator guide rails. There are two specific forms of cooperation: one is sliding fit; the other is rolling fit. For vertically going up and down the elevator, that is, the elevator guide shoe and the elevator guide rail form a sliding pair with each other, and the latter is m...

Problems solved by technology

[0005] Not limited to the above-mentioned patent solutions, although each can embody the technical effects recorded in the technical effect column of its description, there are the following disadvantages: one, due to the lack of a main wheel that forms a rolling pair with the upper surface of the guide rail (the aforementioned patent called the roller or the upper roller) as a temporary emergency substitute protection function, so once the main wheel is damaged, it will affect the guide shoe body (the aforementioned patent is called the base) and even damage the elevator car, and it will also be accompanied by potential safety hazards; The aforementioned main wheel is in a bare state, which is not conducive to the protection of the main wheel, especially when the external foreign matter invades the main wheel, it will affect the smooth effect of its operation and even cause stagnation; thirdly, due to the self-structure of the guide shoe body Unreasonable, thus affecting the connection effect with the car connection seat at the bottom of the elevator car and the reliability of the connection
