Its structure is characterized by that on the machine body a supporting frame is set, said supporting frame is composed of hinged support, supporting oil cylinder, supporting bar and fine tuning device. Said invention also provides the connection mode of all the above-mentioned portion and working principle and operation method of said drilling machine with supporting frame.

Description

technical field [0001] The invention relates to a drilling machine with a support frame, in particular to a drilling machine with a support frame used in underground coal mines. Background technique [0002] Coal mine underground drilling rigs have been widely used at present. At present, the fixing devices of coal mine underground drilling rigs are: one is to hit the ground anchor to fix the drilling machine so that the drilling machine can work normally. Its defect is that it is easy to emit sparks during the ground anchoring process. If the underground gas concentration is high, it will cause a gas explosion. When the drilling machine is working, it is a downward vertical mechanical rotation movement, which has a large rebound force. This rebound force will cause friction between the ground anchor and the ground, sparks will be generated, and the ground anchor will also be loosened, which will reduce the working efficiency of the drilling machine. . The second is to use...
