Embodiment 1

[0021] Such as figure 1 and figure 2 As shown, a kind of numerical control fixed torque vertical bolt wrench of the present invention comprises traveling wheel 1, traveling frame 2, power supply device, drive frame 14 and wrench main body; Said traveling wheel 1 is installed on described traveling frame 2 The two ends of the two ends; the power supply device and the driving frame 14 are installed on the walking frame 2 respectively; the wrench main body is two, respectively installed on the movable driving frame 14; The wrench main body includes a support frame 6, a motor 7, a clutch 8, a torque switch 9, a driver 10, a torque sensor 11, a transmission shaft 12 and a working sleeve 13; the support frame 6 is movably mounted on the drive frame 14, the motor 7 and the clutch 8 are mounted on the upper end of the support frame 6; the torque switch 9 and the driver 10 are mounted on the support frame 6; the torque sensor 11 is mounted on the support The lower end of the frame 6...

Embodiment 2

[0029] Embodiment two is basically the same as embodiment one, the difference is: as figure 2 As shown, the numerically controlled fixed-torque stand bolt wrench also includes a lighting lamp 16, which is installed on one side of the electric control instrument box 3, which is convenient for operation at night. The numerical control fixed torque vertical bolt wrench also includes an operating rod 17, and the operating rod 17 is fixed on one side of the driving frame 14 with bolts, which is convenient for workers to work. The driving frame 14 is provided with a cavity 20 through which the transmission shaft 12 passes.

Abstract

The invention provides a numerical control constant torque vertical bolt wrench which comprises travel wheels, a travel frame, a power supply device, a driving frame and two wrench bodies. The travel wheels are mounted at two ends of the travel frame, the power supply device and the driving frame are respectively mounted on the travel frame, and the two wrench bodies are respectively mounted on the movable driving frame and comprise support frames, motors, clutches, torque switches, drivers, torque sensors, transmission shafts and working sleeves. Torque is easily controlled, on-site operation is convenient, too low torque or too high torque is avoided, the double sleeves independently work, a single sleeve of the double sleeve can work as required, and the numerical control constant torque vertical bolt wrench is adaptable to tightening and loosening operation of various vertical bolts of railway fasteners and turnout junctions.

Description

technical field [0001] The invention relates to the technical field of wrenches, in particular to a numerically controlled constant torque stand bolt wrench. Background technique [0002] At present, the commonly used machines and tools used for the loosening and tightening of railway line sleeper bolts are divided into electric motors and internal combustion engines in terms of power; they are divided into hydraulic transmission and mechanical transmission in terms of transmission methods. The internal combustion type motorized wrench hydraulic motorized wrench is mainly used. Its structure is a mechanical helical gear that transmits impact. The impact part and transmission part are easily damaged, and there are disadvantages such as high failure rate and high maintenance cost. From the perspective of torque control, the current Most wrenches are of impact type and torque display or customized torque through the hydraulic system relief valve. This method is difficult to con...
