Embodiment Construction

[0010] In the figure, the portable abrasive water jet cutting machine for coal mine includes a water tank 1, a water pump 2, a pressure regulating valve 3, a pressure gauge 4, a water pipe 5, a first branch water pipe 6, a second branch water pipe 13, a third branch water pipe 11, Abrasive amount regulating valve 12, water amount regulating valve 10, abrasive tank 7, mixing pipe 8 and spray gun 9; it is characterized in that: the water tank 1 of the portable coal mine abrasive water jet cutting machine is in the same order as the water pump 2, pressure regulating valve 3, and pressure gauge 4 Connected in series through 5 water pipes, the water pump 2 generates pressure so that the water in the water tank 1 flows through the pressure regulating valve 3 and the pressure gauge 4, and then is divided into three branch water flows, the upper, middle and lower branches, and the water flows respectively to the three branch water pipes divided by the water pipe 5. A branch water pipe ...

Abstract

The invention relates to a portable abrasive water jet cutting machine used in a coal mine. A water tank is connected with a water pump, a pressure adjustment valve and a pressure gage in sequence through a water pipe in series; the water pipe is divided into three branched water pipes; a first branched water pipe is connected with the upper end of a barrel-shaped abrasive jar; a second branched pipe is connected with the lower end of the abrasive jar through an abrasive flow regulating valve; a third branched water pipe is connected with a mixing pipe through a water adjusting valve; the mixing pipe extends forwards to be connected with a spray gun; and the abrasive water is jetted out through the spray gun to cut the objects, thus achieving the purpose of the cutting operation. A cold cutting technique of the abrasive water jet is adopted in the cutting machine, thus overcoming the dangers caused by the condition that the gas exists in various hot cutting technique; and the cutting machine is light, is not hot, is smokeless, smell-less, and nontoxic and has no gas generation, is beneficial for protecting the environment, and is suitable for carrying out the safe cutting operation under the inflammable and explosive dangerous occasions and the like.

Description

technical field [0001] The invention relates to a coal mine cutting machine, in particular to a portable coal mine abrasive water jet cutting machine. Background technique [0002] At present, the method of underground coal mine cutting operation is generally to adopt the gas flame cutting method after taking certain protective measures. This gas flame cutting method belongs to thermal cutting, and has a very large However, there is currently no safe, reasonable and effective solution to this problem. Contents of the invention [0003] In order to solve the problem of inflammability and explosion in the process of underground cutting in coal mines, this invention proposes a portable abrasive water jet cutting machine for coal mines. This invention adopts the cold cutting technology of abrasive water jets to overcome various heat Cutting technology may cause danger in the environment with gas, safe and convenient. [0004] The technical solution adopted by the present inv...
