Problems solved by technology

Therefore, if a higher pommel horse frame is selected to meet the large working space below the bottom plane of the frame, it will make it difficult to get on and off the frame, and when working above the frame, there will be a safety hazard due to the high height
However, if a shorter pommel frame is chosen to ensure that the upper part of the frame is lower, the working space below the bottom plane of the frame will be small, and workers need to squat or even lie on the ground to work, which is painful and labor-intensive
Therefore, there is a contradiction in the selection of the pommel horse frame in the prior art
[0003] In addition, in order to support at different heights, although multi-stage telescopic cylinders with larger strokes can be used, relatively expensive models are used to meet larger load-bearing requirements, and the layout is complicated

Embodiment approach

[0038] More preferably, the two lifting devices 10 are arranged in such a manner that the distance between the two lifting devices 10 is adjustable, so that the supporting position can be adjusted correspondingly according to the different models and sizes of the chassis of the supported cranes. Wherein, the two lifting devices 10 can be arranged in various appropriate ways, as long as the distance can be adjusted. Although a specific embodiment will be described in detail below, the present invention is not limited thereto.

[0039] In a preferred embodiment of the present invention, each lifting device 10 may include a first oil cylinder 11 and a second oil cylinder 12, the cylinder body of the first oil cylinder 11 is fixedly connected to the cylinder body of the second oil cylinder 12, The piston rod of the first oil cylinder 11 and the piston rod of the second oil cylinder 12 protrude in opposite directions.

[0040] More preferably, as Figure 1 to Figure 3 As shown, e...

Abstract

The invention discloses a supporting device for assembling a chassis. The supporting device for assembling the chassis comprises a lifting device (10). The lifting device (10) comprises at least two lifting mechanisms, wherein the lifting mechanisms are reversely connected in series. Due to the fact that the two lifting mechanisms are reversely connected in series, the total stroke of the lifting device is the sum of the strokes of the at least two lifting mechanisms, and therefore a long lifting stroke is obtained under the condition that the lifting mechanisms with small strokes are used so as to meet the requirements for different supporting heights.

Description

technical field [0001] The present invention relates to tooling equipment, in particular to a support equipment for crane chassis assembly. Background technique [0002] Crane chassis (especially the all-terrain chassis of super-large-tonnage cranes) generally adopts a platform-type assembly method supported by a saddle-horse frame. During assembly, a plurality of pommel horse frames are generally used to support a certain position of the frame along the length direction of the chassis frame, so that the frame is fixed firmly as the assembly reference part, and then the parts to be installed are installed on the frame one by one according to a certain assembly sequence. Finally complete the assembly process of the entire chassis. The prior art mainly adopts various saddle frames with different heights and different widths to support different positions of the vehicle frame. Chassis assembly is distinguished according to the space position, and there are mainly two assembly...
