Flexible lifting appliance for cab

Abstract

The invention discloses a flexible lifting appliance for a cab. The flexible lifting appliance is provided with a lifting appliance main frame, the lower end of the lifting appliance main frame is symmetrically connected with front suspension arms in a sliding mode, the lower end of the lifting appliance main frame is connected with rear suspension arms used in cooperation with the front suspension arms in a sliding mode, the symmetrical front suspension arms and the independent rear suspension arms are connected with a left door frame, a right door frame and a rear window frame of the cab correspondingly, three-point suspension of the upper part of the cab is realized, a front suspension arm adjusting assembly and a rear suspension arm adjusting assembly are arranged on the inner side of the lifting appliance main frame, the front suspension arm adjusting assembly is used for adjusting the distance between the symmetrical front suspension arms so as to be matched with the width of the cab, and the rear suspension arm adjusting assembly is used for adjusting the vertical distance between the rear suspension arms and the front suspension arms so as to be matched with the length of the cab, three-point suspension is carried out on the upper portion of the cab, the influence on sealant coating and PVC coating processes on the local portion of the lower portion of the cab is effectively avoided, the suspension points are the left door frame, the right door frame and the rear window frame of the cab, and it can be guaranteed that long cabs of various models are horizontally suspended and do not incline.

Description

technical field [0001] The invention relates to the technical field of frame bushing press-fitting machines, and the specific field is a flexible sling for a cab. Background technique [0002] Generally, the gluing spreader for commercial vehicles (truck cabs) adopts the method of hanging the left and right side windows and the lower front part of the cab (see figure 1 ), because the spreader legs extend to the lower part of the cab, this kind of spreader has the following two problems: 1. It affects the sealant and PVC coating process of the lower part of the cab; The position is basically in front of the cab, which causes some extended cabs to tilt backwards, which affects the transfer of subsequent processes. Contents of the invention [0003] The purpose of the present invention is to provide a cab flexible sling to solve the technical problems mentioned in the background art above. [0004] A cab flexible spreader, comprising: [0005] The main frame of the spreade...
