Internal combustion electric bolt spanner

Abstract

The invention provides an internal combustion electric bolt spanner. A generator, a current controller, a motor, a speed reducer, a sleeve shaft, a sleeve and a sleeve control mechanism are arranged on a frame; a traveling mechanism is arranged below the frame; the generator supplies power and electric energy, or the generator and a lithium ion battery pack are connected to supply the power and the electric energy jointly; the power and the electric energy are modulated by the current controller and then transmitted to the motor to drive the motor to rotate; and an output shaft of the motor is connected with the speed reducer, is decelerated by the speed reducer and drives the sleeve connected to the lower end of the sleeve shaft to rotate. The spanner is miniaturized, light in weight and easy to operate, and a nut is convenient to detach when a steel rail is replaced by a railway maintenance department on line; the lithium ion battery pack supplies main energy, and a micro intermediate frequency generating set supplies auxiliary energy, so that the spanner has the characteristics of achieving low energy consumption and saving energy by 40 percent; and torque is controlled by controlling current, so that the spanner is high in accuracy.

Description

technical field [0001] The invention belongs to the technology of accurately loosening and tightening rail bolts and nuts, and in particular relates to a small internal combustion electric bolt wrench for railway maintenance and construction operations. [0002] Background technique [0003] At present, for the tightening and loosening of railway track bolts and nuts, a 380V generator set is used to drive an AC motor through a cable to disassemble the track bolts and nuts or directly use an internal combustion engine to drive the gear reducer to directly disassemble the track bolts and nuts. Its disadvantages are large dimensions, heavy equipment, large energy consumption, low efficiency, and low precision; moreover, due to the low efficiency of disassembly and installation, it is difficult to meet the requirements of short-term operation in the skylight, which often affects the passage of trains, and there is also a certain degree of safety Hidden danger.
