Fuel tank capable of being flexibly fixed and loading machine

Abstract

A fuel tank capable of being flexibly fixed and a loading machine comprise a vehicle frame, the vehicle frame is connected with a balance weight, the fuel tank is arranged between the vehicle frame and the balance weight, the balance weight is provided with a balance weight platform used for bearing the fuel tank, the balance weight platform is provided with a protruding limiting block, and the lower portion of the fuel tank is provided with an installation groove matched with the protruding limiting block for use. A double-end stud and a limiting spring are arranged between the fuel tank and the frame. According to the fuel tank capable of being flexibly fixed and the loading machine, when the balance weight needs to be detached or replaced, the fuel tank can be rigidly connected and hung to the fuel tank mounting plate of the rear frame, at the moment, the balance weight has no supporting effect on the fuel tank and can be separated, related pipelines are not affected, temporary transfer of a main machine without the balance weight is facilitated, and the loading machine can be conveniently and rapidly fixed when a container is loaded. According to the loading machine, cost reduction and efficiency improvement of the loading machine are achieved, detachability and maintainability are both considered, and the loading machine is reliable in structure and easy to achieve.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a flexible and fixed fuel tank and loader. Background technique [0002] The rear fuel tank of the traditional loader is generally fixed on the fuel tank mounting plate at the rear of the rear frame by bolts. The tailgate on the rear frame near the fuel tank mounting plate is used to hold the counterweight. When the loader is turning at high speed or driving on an uneven road, the loader will experience bumps, and the counterweight with a large mass will cause the rear frame to twist due to the frequent bumps and be fixed at the rear of the frame. The mounting plate of the fuel tank will also be bent due to torsion, which will easily cause the bolts to break and the fuel tank to be bent and cracked, which has a greater safety hazard. In order to increase the rigidity of the fuel tank and the rigidity of the rear frame in the traditional reinforcement installation ...

AI Technical Summary

Problems solved by technology

When the loader is turning at high speed or driving on an uneven road, the loader will experience bumps, and the counterweight with a large mass will cause the rear frame to twist due to the frequent bumps and be fixed at the rear of the frame. The mounting plate of the fuel tank will also be bent due to torsion, which will easily cause the bolts to break and the fuel tank to be bent and cracked, which has a greater safety hazard

In order to increase the rigidity of the fuel tank and the rigidity of the rear frame in the traditional reinforcement installation method, the fuel tank is fixed on the counterweight protective bottom plate through straps, and then the protective bottom plate is installed on the counterweight and finally fixed on the frame. This method requires a separate counterweight guard to support the fuel tank, and the fuel tank and related pipelines need to be removed when replacing the counterweight, which greatly affects the efficiency of disassembly and assembly, and this reinforcement method only relieves the torsion of the rear frame To a certain extent, prolonging the service time of the fuel tank has not fundamentally solved such problems, and during the operation of the loader, it is very easy to cause the guard plate to be hit and cause deformation, which may cause the risk of failure of the fuel tank
