The invention discloses an internal combustion bolt wrench. The bolt wrench comprises an oil tank and an accelerator control switch and further comprises a gear control mechanism which comprises a case to which a shaft is fixed. The shaft is sleeved with a connection plate and a reset spring of which one end is fixedly connected with the connection plate. The other end of the reset spring is fixedly connected with the case. A first steel wire rope clip and a second steel wire rope clip are fixed to the connection plate separately. A first steel wire rope connected with an oil port switch of the oil tank is fixed to the first steel wire rope clip. A second steel wire rope connected with the accelerator control switch is fixed to the second steel wire rope clip. The inner side of the case is connected with a slide plate. The outer side of the case is provided with a rotary knob connected with the slide plate through a transmission assembly, and the rotary knob rotates to drive the slide plate to move relative to the connection plate to limit the maximum rotation angle of the connection plate. According to the internal combustion bolt wrench, the maximum output torque of the wrench can be adjusted according to the need, and thus requirements for disassembly and assembly of different bolts are met. Moreover, the internal combustion bolt wrench is simple in structure and convenient to use.
Description
technical field [0001] The invention relates to the technical field of railway auxiliary equipment, in particular to an internal combustion bolt wrench. Background technique [0002] The internal combustion bolt wrench is a special tool suitable for daily maintenance and repair of railway lines. It has the characteristics of lightness, maneuverability, high efficiency and quickness. Its working principle is roughly as follows: the engine outputs the rotational torque, through the clutch, transmission shaft, and bevel gear reversing reduction mechanism to realize the reversing and deceleration of the rotating torque, and the torque after reversing and decelerating is transmitted from the connecting shaft to the power storage device On the acting impact force mechanism, and then realize the loosening and locking operation of the nut on the bolt through the sleeve. [0003] Commonly used internal combustion bolt spanners in the prior art include a frame, a power mechanism, a r...
