Excavator platform bracket fixing structure and platform including the fixing structure

Abstract

The invention discloses an excavator platform bracket fixing structure and a platform including the fixing structure, including: a platform, a plurality of bracket fixing structures overlapped on the platform, and the bracket fixing structure includes: an engine bracket; The engine support leg is installed on the upper part of the engine support through bolts; the shock absorber is installed on the engine support leg, and the shock absorber is connected with the upper part of the engine support through bolts; the lock A tightening screw, the locking screw fastens the shock absorber. Using the present invention, the engine bracket is divided into two parts, the bent plate and the vertical plate, which are welded and connected together, which effectively saves the production cost, reduces the amount of welding and processing, and improves the production efficiency. At the same time, through the design of the ribs, the strength is effectively improved. Moreover, the vertical plate of the engine support is lapped on the main beam of the platform to effectively improve the rigidity, and reduce the impact of the impact of the excavator on the weld seam of the engine support and the cracking of the base material.

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
