Problems solved by technology
[0003] The problem now is that when the drilling rig is drilling, the fuselage will shake or the shape of the top of the tunnel will cause the force transmitted by the support to the column to deviate from the axial direction of the piston rod, which will cause the piston rod to bend and deform, resulting in failure of the support

A drilling machine with an anti-deformation top support comprises a machine frame. A top support assembly is fixed to the machine frame. The top support assembly comprises an oil cylinder. A stand column is arranged at the top of a piston rod of the oil cylinder. A supporting part is arranged at the top of the stand column. A fixing sleeve is fixed to the machine frame. The oil cylinder is sleeved with the fixing sleeve, and a slideway is formed between the fixing sleeve and the oil cylinder. A protection sleeve is arranged in the slideway. The lower surface of a top panel of the protection sleeve is in contact with the surface of the top of the piston rod. The stand column penetrates out of the top panel of the protection sleeve. The top panel of the protection sleeve is in clearance fit with the stand column. Compared with the prior art, the drilling machine has the beneficial effects that the drilling machine is provided with the fixing sleeve and the protection sleeve, the radial component force of the lateral force transferred to the stand column from the supporting part can be effectively counteracted, only the axial component force remains when the lateral force is transferred to the piston rod from the stand column, and the direction of the axial component force is identical to the axial direction of the piston rod, so that the piston rod is not prone to bending or deformation, and accordingly the supporting balance of the drilling machine is more stable.
Description
technical field [0001] The invention relates to a coal mine tunnel drilling machine. Background technique [0002] The drilling rig used for mining in the mine of present coal mine carries out gas detection to the mine before coal mining, and it is exactly to be drilled in the tunnel for detection. When drilling, the reaction force of the ore body to the drilling rig is too large, which will cause the drilling rig to roll over and other accidents. Therefore, a top support is provided on the drilling rig body to enhance its stability. Such as figure 1 The top of the piston rod 11 of the oil cylinder of the top supporting part 1 is provided with a column 12, and the top of the column 12 is provided with a support part 13, and the support part 13 can directly support the top (ceiling) of the tunnel. When it works, the piston rod 11 of the oil cylinder 1 stretches out upwards until the supporting part 13 reaches the top (ceiling) of the tunnel. In order to make the supportin...
