Abstract

The invention provides a hydraulic shock vibration system in multi-functional engineering equipment, which aims to solve the technical problem that: engineering equipment that a base body of an excavating machine is assembled with other work heads is integrated with excavation, rock drilling, frozen-clay drilling and crushing functions, which can reduce the cost for engineering machinery and also greatly improve the operation efficiency at the same time; but a bit of a down hole drill needs pneumatic power, the down hole drill has pneumatic impact; however, the excavating machine can only provide hydraulic powder, which becomes a bottleneck for restricting the equipment. The hydraulic shock vibration system has the key points that: the system is provided with the base body of the excavating machine; the system is characterized in that: a guide rod of the bit of the down hole drill is provided with a multi-stage propulsion oil cylinder, an air compressor is arranged on the back of a hydraulic system of the excavating machine, a motor of the air compressor is substituted by a hydraulic motor, and a pneumatic output tube of the air compressor is connected with a slag blowing wind pipe of the down hole drill. The use of the hydraulic shock vibration system is to implement multi-functional engineering operations.

Description

technical field [0001] The invention relates to a hydraulic shock vibration system in combined multifunctional engineering equipment. The combined multifunctional engineering equipment refers to the engineering equipment integrating the functions of excavation, rock drilling, frozen soil drilling and crushing. Background technique [0002] Modern warfare requires troops to move faster and faster, and mobile warfare has become the main combat mode. Under such conditions, military engineering machinery must have a faster maneuvering speed in order to complete the accompanying engineering support tasks in order to ensure the smooth completion of engineering tasks. . At present, to complete a tunnel operation task, various construction machinery such as bulldozers, hydraulic down-the-hole drilling rigs, permafrost drilling rigs, and excavators are required to be on site and work at the same time. Sometimes, due to the small working area, several construction machines are on site...
