Abstract
The invention relates to an engine-driven steel rail bolt wrench used for loosening and tightening a steel rail bolt during railway maintaining. The engine-driven steel rail bolt wrench is mainly composed of a frame, a handrail, a traveling wheel, an engine, a worm type reduction gear, a torque limiter, a commutator and a wrench head. The engine-driven steel rail bolt wrench is characterized in that the engine drives a belt to drive the worm type reduction gear, the torque limiter is arranged on the worm type reduction gear, and a gear oil pump is shaft-driven by a worm shaft and supplies oil to an oil cylinder of the torque limiter. The worm shaft delivers a torque to a reverser through a coupler, and an output shaft of the reverser drives the wrench head through a pair of jaw clutches. The engine-driven steel rail bolt wrench has the advantages that the jaw clutches are totally separated when a set torque is achieved, and the wrench head can not be locked with a nut. The torque can be adjusted precisely by adjusting oil pressure, repeating precision of the torque is high, a torque value can be displayed through the oil pressure, work is reliable, and the service life is long.
Description
Technical field:
