Novel large torque roof bolter

Abstract

The invention discloses a novel large torque roof bolter. The novel large torque roof bolter includes a tip, a handle, a landing leg, a fixing sleeve, a conversion handle, a reduction box shell, a drill sleeve, a water blocking sleeve, a motor shell, a support ring, a regulating shaft, a fixing sleeve, an operating arm, a support plate, a handle frame, a back cover plate, a cylinder head inner hexagon screw, an air inlet, an auxiliary shaft, a drive gear shaft, a main shaft, a bearing, and an air outlet. The tip is arranged at the bottom end of a base, equipment is convenient to fix. The landing leg is arranged at the top end of the base, the fixing sleeve is arranged at the top end of the handing leg, the fixing sleeve fastens the landing leg and the back cover plate, so that the equipment is steadier. The fixing sleeve is rotationally connected with the fixing sleeve through the regulating shaft, the operating arm is arranged in the fixing sleeve, and the equipment is convenient to operate. The air inlet is arranged at the top end of the back cover plate, and the air outlet is arranged at the position, depart from one end of the air inlet, of the top end of the base plate. The air outlet drives the auxiliary shaft and the drive gear shaft to rotate, the gear is arranged at the top end of the drive gear shaft, the angle of the conversion handle is rotated, and the position ofthe gear can be changed, so that the effect of changing torque is achieved.

Description

technical field [0001] The invention relates to a bolter, in particular to a novel high-torque bolter, which belongs to the technical field of machinery. Background technique [0002] Bolting machine, also known as soil nailing machine, bolting rig or pneumatic impact machine, is mainly used for rock and soil bolting, roadbed, slope treatment, underground deep foundation pit support, tunnel surrounding rock stability, prevention of landslides and other disasters. Underground engineering support and high-rise building foundation treatment, also suitable for deep foundation pit spray protection, non-prestressed bolt support for slope soil nailing engineering. [0003] However, there are many deficiencies in the current bolter, such as the non-switchable torque of the traditional bolter, which is not easy to operate and use. Therefore, a new type of high-torque bolter is proposed to solve the above problems. Contents of the invention [0004] The object of the present invent...
