Embodiment Construction

[0029] The structure of the high-precision internal combustion bolt wrench of the present invention is described in detail below in conjunction with the accompanying drawings:

[0030] Such as figure 1 , figure 2 , image 3 Shown: the high-precision internal combustion bolt wrench of the present invention includes a frame 1 on which an internal combustion engine 2, a speed change device 3, a quill shaft 4, a sleeve 5, a sleeve height adjustment mechanism 6 and a sleeve manipulation mechanism are arranged 7. The front traveling wheel 8, the rear traveling wheel 9 and the auxiliary support shaft 10 are arranged under the frame 1. The wrench rides on a steel rail through the front traveling wheel 8 and the rear traveling wheel 9, and is supported by the supporting shaft 10 on the other side. One rail track forms a stable support; when working, push the frame 1, which can walk on the two rails in a balanced manner.

Abstract

The invention provides a high precision internal combustion bolt spanner, which comprises a frame and is characterized in that: the frame is provided with an internal combustion engine, a speed change gear, a sleeve shaft, a sleeve, a sleeve height adjusting mechanism and a sleeve control mechanism; a front traveling wheel, a rear traveling wheel and an auxiliary support shaft are arranged below the frame; an output shaft of the internal combustion engine serving as power extends into the speed change gear, the rotation speed of the internal combustion engine is reduced to a rotation speed meeting a process requirement through the speed change gear, and power output by the speed change gear drives the sleeve shaft to rotate, so that the sleeve arranged at the lower end of the sleeve shaft is driven to rotate. The spanner is miniaturized, and has light weight under mechanical and hydraulic control, the torque is accurately adjusted, and the spanner is easily used and operated for anchoring railway track bolts and nuts by a rail-track engineering department on line; and the torque is convenient to adjust at high accuracy, and is adjusted hydraulically, so that the spanner hardly fails.

Description

technical field [0001] The invention relates to a wrench for disassembling and assembling nuts and bolts of rail rails, in particular to a small high-precision internal combustion bolt wrench for railway maintenance. [0002] Background technique [0003] At present, the bolts and nuts of railway rails are disassembled by manual T-type wrench or electromechanical wrench, which is inefficient and labor-intensive for workers; moreover, when tightening each bolt and nut, the degree of tightening (tightening force) is difficult to guarantee Uniformity, or it is difficult to ensure that the tightening degree is roughly the same, resulting in inconsistent tightening degrees between different bolts and nuts, and their stress in the rail is not uniform, which affects the force balance of the rail. Moreover, due to the low efficiency of disassembly and installation, it is difficult to meet the short-term operation requirements in the skylight, which often affects the passage of trai...
