Pneumatic crawler hydraulic jumbo

Abstract

The invention discloses a pneumatic crawler-type hydraulic drill carriage which comprises a carriage body, a travelling gear, a working device for drilling connected with the carriage body, a hydraulic system for driving the devices, and an operating device; a pneumatic motor is used as power of the hydraulic system and operation of the drill carriage; an operating device, which adopts closed loop design, is used for driving the pneumatic motor, the pneumatic system, the hydraulic system and the various acting components to act; the travelling device is crawler-typed; a swinging device, which consists of a swinging arm and a cylinder, is arranged at the front of the carriage body; the front end of the swinging device is connected with the working device for drilling by a universal rotating device; the working device consists of a feeding device which comprises a supporting device, a secondary cylinder, and a chain pushing mechanism; and the pneumatic crawler-type hydraulic drill carriage uses a method combining water and gas to clean the boreholes. The pneumatic crawler-type hydraulic drill applies especially to mass drilling work sites of which change continuously; the whole carriage is free of electric devices and the pneumatic crawler-type hydraulic drill applies particularly to high gassy mine and can carry out universal hole drilling.

Description

technical field [0001] The present invention relates to a kind of mechanical device, specifically a kind of drilling equipment suitable for anchor cable support and gas drainage drilling in coal mines that can move automatically, that is, a crawler-type drilling equipment with air motor as the Powered fully hydraulic tunnel drilling rig. Background technique [0002] In the coal mining industry, safety requirements are increasing day by day, and anti-burst holes and anchor holes play a very important role in safe production. Anti-burst holes and anchor holes are distributed on the four walls of the tunnel, and there are many in every direction. At present, in my country's coal mine industry, the anti-outburst and anchor holes are all adopted pneumatic auxiliary machines and anti-outburst drilling rigs. In the construction of the side anchor cable hole and the anti-outburst hole, when utilizing the pneumatic helper and the anti-outburst drilling machine to drill holes, all ...

AI Technical Summary

Problems solved by technology

The disadvantage of this patented technology is that the rotation angle of the drilling rig is relatively small, which is not suitable when drilling holes in different directions at the same place

Therefore, the electrical equipment used in the above-mentioned equipment has the possibility of generating sparks, and there are unsafe factors in all of them.
