Abstract

The invention provides a lift car underframe. The lift car underframe comprises main beam frames and an auxiliary beam frame, the two main beam frames are arranged in parallel and are connected with an elevator car, the auxiliary beam frame is arranged between the main beam frames vertically, the auxiliary beam frame and the main beam frames are fixedly connected in a welded manner, the main beamframes comprise the first beam frame and the second beam frame, the first beam frame and the second beam frame are the same in structure, the first beam frame comprises an outer steel plate, an innersteel plate and a connecting steel plate vertically arranged between the outer steel plate and the inner steel plate, connecting frames for connecting with the elevator car is arranged among the outersteel plate, the inner steel plate and the connecting steel plate, a connecting corner plate is arranged at the outer end of the first beam frame, an abut-joint plate is arranged at the inner end ofthe first beam frame, and the first beam frame and the second beam frame are fixedly connected through the abut-joint plate. The main beam frame used for bearing a car comprises the first beam frame and the second beam frame, compared with an existing underframe, the size is reduced by a half, the main beam frame is connected with the elevator car through the connecting frames and the connecting corner plate at the outmost end, and the connecting strength and the bearing capacity are ensured.

Description

technical field [0001] The invention belongs to the technical field of elevators, in particular to a car underframe. Background technique [0002] The existing elevator underframe is a frame-type integral structure, which has a large volume and high manufacturing cost, and also has the problem of inconvenient assembly during elevator assembly. Contents of the invention [0003] In view of this, the present invention aims to provide a car underframe to solve the problems of large volume, high cost and inconvenient assembly in the hoistway of the elevator underframe. [0004] In order to achieve the above object, technical solution of the present invention is achieved in that way: [0005] A car chassis, including a main beam frame and an auxiliary beam frame, the two main beam frames are arranged in parallel and connected with the elevator car, the auxiliary beam frame is vertically arranged between the main beam frames, and the auxiliary beam frame is welded to the main b...
