Abstract

The invention relates to a full-hydraulic crawler pump truck for the coal mine underground directional drilling. A power-head drilling machine needs to be equipped with a sludge pump assembly in the directional drilling process, and the sludge pump assembly is used for providing the high-pressure water so as to drive a motor on the bottom of a hole to realize the directional drilling. At present, the sludge pump assembly which is matched with the directional drilling adopts electric-driving belt transmission and clutch control and is separated from the drilling machine, the sludge pump assembly is moved for a short distance mainly by the manpower or through other tools, so that the weaknesses such as poor integration of the directional drilling system, slow moving speed, long assisting time, large labor intensity of workers and low application safety exist. The full-hydraulic crawler pump truck for the coal mine underground directional drilling comprises a hydraulic-drive sludge pump assembly, two electromagnetic starters, a locomotive lamp assembly, a gas sensing circuit breaker, a plurality of reversing valve banks, an operating platform, an oil tank, a motor pump assembly, a cooler, a crawler chassis assembly and a pump truck platform. The full-hydraulic crawler pump truck has the advantages of good integration, advanced performance, simplicity and convenience in operation and safety in operation.

Description

technical field [0001] The invention belongs to the field of drilling machinery, in particular to a fully hydraulic crawler pump vehicle for directional drilling in underground coal mines. Background technique [0002] The power head drilling rig needs to be equipped with a mud pump assembly for directional drilling, which is used to provide high-pressure water to drive the motor at the bottom of the hole to achieve directional drilling. At present, most of the power head drilling rigs used for directional drilling are crawler self-propelled. Most directional drilling rigs need to be equipped with independent electric drive mud pumps and electromagnetic starters. The auxiliary time of drilling rigs is long and the labor intensity of workers is high. Although some integrated crawler directional drilling rigs are equipped with mud pumps and electromagnetic starters, they occupy a large space, require high roadway sections, are extremely inconvenient to use, and have poor appli...
