A cutting machine with overload protection

Abstract

Disclosed is a cutting machine with the overload protection function. The problems that excessive road cutting is performed, incomplete cutting is performed and a cutting machine does not have the overload protection function due to the fact that the depth is artificially set in the cutting process of a cutting machine are effectively solved. The construction time can be shortened, the construction progress can be accelerated, the technical requirement of operators is lowered, the operators and a cutting machine body are protected, and the cutting machine has generalization; the cutting machine comprises a machine frame, a pushing handle, wheels, a cutting piece, a small hydraulic station, a control system and a hydraulic motor. The cutting machine is simple and reasonable in structure, vertical motion of the cutting piece can be controlled while cutting is performed, it is ensured that a cut road can be completely separated from a soil matrix, secondary construction is avoided, the overload protection function is added while cutting is performed, the hydraulic motor is adopted as power, the protection effect can be achieved when the stress of the cutting piece changes suddenly, and the cutting piece and a transmission element are prevented from being deformed or damaged by excessive strength.

Description

technical field [0001] The invention relates to the technical field of building and road construction equipment, in particular to a cutting machine with overload protection. Background technique [0002] With the development of transportation, concrete roads have been vigorously constructed in road construction, but the damage of concrete roads is quite serious, and the road management department needs to repair the roads. Usually, an impact hammer is used to divide the damaged pavement into a small piece of concrete, and then re-pour new concrete. This repair method is laborious, unevenly divided, and inefficient; there is also a cutting machine that sets the cutting depth at the rear of the machine frame. Adjust the screw rod, but the depth is not easy to grasp. The depth is preset each time, and it needs to be reset for different cutting depths next time, which is not convenient. However, the depth of the road is different. Using the preset depth may overcut or cut the c...

Problems solved by technology

[0005] In view of the above situation, in order to overcome the defects of the prior art, the object of the present invention is to provide a cutting machine with overload protection, which effectively solves the problems caused by the artificially set depth of the cutting machine during the cutting process, which leads to overcutting of roads and undercutting. It can save construction time, speed up the construction progress, reduce the technical requirements of operators, protect the operators and the cutting machine itself, and make it more popular
