Excavator platform support fixing structures and platform comprising same

Abstract

The invention discloses excavator platform support fixing structures and a platform comprising the same. The platform comprises a platform body, and a plurality of support fixing structures are connected to the platform body in a lap-joint mode. Each support fixing structure comprises engine supports, engine support legs, shock absorbers and locking nut pieces, wherein each engine support leg is mounted on the upper portion of the corresponding engine support through a bolt; each shock absorber is mounted on the corresponding engine support leg and connected with the upper portion of the corresponding engine support through a bolt; and each locking nut piece is used for fastening the corresponding shock absorber. According to the excavator platform support fixing structures and the platform comprising the same, each engine support is formed by welding a bent plate and a vertical plate in one position, the welding quantity and machining quantity are reduced while manufacturing cost is effectively reduced, and production efficiency is improved. Meanwhile, through the design of reinforcing ribs, the strength is effectively improved. Moreover, the vertical plates of the engine supports are connected to a girder of the platform in a lap-joint mode, so that rigidity is effectively increased, and the cracking influence of impact during work of an excavator on welds and parent metal of the engine supports is reduced.

Description

technical field [0001] The invention relates to the technical field of a fixing structure, in particular to an excavator platform bracket fixing structure. Background technique [0002] In the known excavator platforms, the engine is the core of various mechanical equipment, especially for excavators. In actual assembly work, since the engine bracket of the excavator rotary platform is prone to welding deformation during welding, when installing the engine, The four outriggers of the engine are not concentric with the four engine supports of the slewing platform. [0003] figure 1 It is the general assembly drawing of the engine installation and fixing structure for the excavator of the patent No. 20112040675.1, figure 2 It is a schematic diagram of the main structure of the engine installation and fixing structure of the patent No. 20112040675.1, image 3 For the front view of the main structure of the engine installation and fixing structure for the excavator patent No...

AI Technical Summary

Problems solved by technology

[0005] (1) When the bolts are loose, the engine will move horizontally, and it is easy to cause damage when subjected to various impacts;

[0006] (2) The surface of the engine bracket is serrated to increase the production cost;

[0007] (3) The rigidity of the engine bracket is insufficient, and it does not have the overall anti-seismic function;

[0008] (4) There are two welds between the fixed plate and the engine bracket, which increases the processing cost and welding cost of the engine bracket
