Caterpillar belt self-walking type tunnel drilling rig hydraulic system

Abstract

The invention is a hydraulic system of a pedrail self-walking tunnel driller. With the prior art, a fully-hydraulic tunnel driller is moved manually or by a walking mechanism for a short distance, and a rotation speed and a torque can only be controlled in the manner of drilling by power turning at a hole mouth and in the manner of manual variation. Thus, the prior tunnel driller is provided with the problem of the lagged control, the low control precision, the low efficiency of the hydraulic system, and so on. The hydraulic system of a pedrail self-walking tunnel driller of the invention comprises a pedrail walking loop, a power head turning loop, a feeding and pulling loop, a driller stabilizing loop, a brake loop of a principal axis of the power head, and so on, and can realize the straight walking and turning of the driller, the turning and feeding of the power bead, the interacting of a chuck and a clamping device with the feeding and pulling, the braking of a principal axis of a turning device, the floating of a feeding cylinder, and other functions. Moreover, as the hydraulic feedback control system and the interacting function are adopted, the driller moving is rapid and convenient, the labor intensity is low, the driller drilling techinics is widely applicable, the operation is simple and the system is energy-saving.

Description

technical field [0001] The invention relates to drilling machinery, in particular to a crawler self-propelled tunnel drilling machine hydraulic system. Background technique [0002] At present, the relocation of full-hydraulic tunnel drilling rigs mainly relies on manual handling or short-distance movement of walking mechanisms. Only the hole power rotary drilling method can be used, and the speed and torque are controlled by manual variables, which has control lag and low control accuracy. , Low efficiency of the hydraulic system and other issues. Contents of the invention [0003] The object of the present invention is to provide a crawler self-propelled tunnel drilling rig hydraulic system with convenient operation, high control precision and quick response. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] The hydraulic system of crawler self-propelled tunnel drilling rig includes drilling rig support an...
