Problems solved by technology

The existing auxiliary wheel seat is an integrally formed iron or steel casting, including the seat body and the auxiliary wheel shaft perpendicular to the seat body. The casting process consumes energy, has a large volume and mass, increases the operating load of the escalator, and wastes electric energy. If the casting body The appearance of air holes will also reduce the overall strength of the auxiliary wheel seat
In addition, the seat body is connected with the lower end of the tripod, the flange at the lower end and the kick plate assembly through nuts, and the auxiliary wheel shaft is sleeved on the auxiliary wheel shaft, and the screw holes and the auxiliary wheel shaft need to be processed by turning, milling, etc., requiring complex processing Fixtures and multiple processes make it difficult to process such an integrally cast auxiliary wheel seat, the scrap rate is high, and the consistency of the product is difficult to guarantee, resulting in high manufacturing costs

Abstract

The invention relates to a welding-type jockey pulley base of a stainless steel escalator step, belonging to the manufacturing field of escalators. The traditional structure is formed by casting integrally and has the problems of energy consumption, low percent of pass, high manufacturing cost and poor consistency. The welding-type jockey pulley base of the stainless steel escalator step comprises a jockey pulley shaft and a base body with a mounting hole, wherein the jockey pulley shaft and the base body are detachable members which are integrally welded and fixed; the jockey pulley shaft iscylindrical and comprises a jockey pulley mounting part on the upper part, a shaft lever in the middle part and a shaft base connection end on the lower part; the base body is a board stamping part comprising a triangular bottom face and a side wall which is perpendicular to the bottom face and provided with an opening at one end; a connection chamfer is arranged at the joint of the triangular bottom face and the side wall; and the vertex angle of the triangular bottom face is provided with a jockey pulley mounting hole in which the jockey pulley mounting part is inserted. The invention has the advantages of detachable production, convenient processing, low manufacturing cost, energy saving, light self weight and good strength, and is suitable for detachable-type stainless steel steps.

Description

【Technical field】 [0001] The invention relates to a welded auxiliary wheel seat of a stainless steel escalator step assembled in separate parts, and belongs to the field of escalator manufacturing. 【Background technique】 [0002] Escalators are usually installed in large places such as airports, exhibition halls, and shopping malls, which include multiple sections of stainless steel steps connected to each other to form a closed chain cycle. Each step is composed of a pedal assembly for carrying passengers, a kick plate assembly, and a set of tripods with a main wheel axle seat and an auxiliary wheel seat. The main wheel shaft passing through the main wheel shaft seat pulls the escalator steps, and the auxiliary wheels on the auxiliary wheel seat support the steps, so that the steps move on the escalator track. The existing auxiliary wheel seat is an integrally formed iron or steel casting, including the seat body and the auxiliary wheel shaft perpendicular to the seat body...
