Handheld hydraulic drilling machine

Abstract

The invention discloses a handheld hydraulic drilling machine; a water supply structure is installed on a machine body; water flowing channels for supplying the water are formed in a drill stem and a drill bit; when the machine works, the high pressure water flows out from a water outlet of the drill bit to assist rock drilling and simultaneously cools the drill bit, and carries out dust falling treatment on environment, and trouble shootings can be carried out in a manner of a forward-reversal rotation of the drilling machine and pressing of the high pressure water in jamming of a drilling tool; a hydraulic support claw is further installed on the machine body and can be used for locating the machine body at a rock drilling position so as to provide a support force and simultaneously assist the machine body to exert a pressure on the rock drilling position by a self weight of the machine body, thereby improving the convenience in operation and reducing the labor intensity. According to the drilling machine, the shortage brought by a pneumatic rock drill to which working air is supplied in a long distance to cause a loss is solved, and the purposes of improving the working environment, and reducing the equipment cost and the maintenance cost are achieved; meanwhile, profit reduction caused by using a lot of air compressors is avoided; and the risk of using a lot of high-pressure pressure containers is reduced.

Description

technical field [0001] The invention relates to a rock drilling tool used in tunnels and mines, in particular to a hand-held hydraulic drilling machine. Background technique [0002] At present, rock drilling tools such as tunnels and mines basically use pneumatic rock drills, especially in tunnel engineering. The high-pressure air supply distance of the pneumatic rock drill generally does not exceed 2000 meters, but with the rapid development of my country's high-speed rail technology, extra-long two-lane tunnels are becoming more and more frequent. , so it is necessary to use an air compressor to enter the cave to assist the air supply into the cave. [0003] However, after the air compressor enters the hole, on the one hand, it will generate a lot of heat during use, which will affect the construction environment; on the other hand, it will require an extremely large amount of clean air. If the required clean air cannot be supplied in time, It will cause a great drop in ...

Problems solved by technology

[0003] However, after the air compressor enters the hole, on the one hand, it will generate a lot of heat during use, which will affect the construction environment; on the other hand, it will require an extremely large amount of clean air. If the required clean air cannot be supplied in time, It will cause a great drop in production capacity; it is usually difficult to meet this requirement in the use of extra-long tunnels, and with the deepening of tunnel construction, the number of air compressors required will gradually increase, which leads to extremely high equipment efficiency. At the same time, a large amount of equipment needs to be invested, which increases equipment costs and maintenance costs, and the use of a large number of air compressors will have high safety hazards
