Embodiment 1

[0024] Such as figure 1 As shown, the vertical dual electric torque wrench of the present invention includes a vertical dual electric torque wrench, including a housing 11, a power output assembly, and a sleeve 12. The power output assembly is installed in the housing 11, and the power output assembly includes two batteries The motor 13 is connected to the battery, and the output shaft at the lower end of the motor 13 is drivingly connected to the sleeve 12.

[0025] A vertical rod 14 is fixedly installed at the upper end of the housing 11, the axis of the vertical rod 14 coincides with the axis of the output shaft of the motor 13, a vertical operating handle 15 is installed on the upper end of the vertical rod 14, and the middle of the vertical operating handle 15 arranged horizontally It is fixedly connected with the upper end of the vertical rod 14. The vertical rod 14 is a telescopic rod. In this embodiment, the vertical rod 14 includes an upper connecting rod 16 and a lower...

Embodiment 2

[0040] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the vertical rod 14 includes an upper connecting rod 16, a lower connecting rod 17 and a fixed rod 34, and two horizontally arranged two are provided on the outer circumference of the upper connecting rod 16. There are two first mounting holes 32, the lower connecting rod 17 is a hollow tube, the upper connecting rod 16 is inserted into the lower connecting rod 17, and the outer circumferential surface of the lower connecting rod 17 is provided with a number of second mounting holes 33, the second mounting holes 33 The distance between the two is equal, the axis of each second mounting hole 33 is parallel to the axis of the first mounting hole 32, the fixing rod 34 is fixedly inserted into a second mounting hole 33, and the fixing rod 34 passes through the first mounting hole 33. A mounting hole 32, the right end of the fixing rod 34 is provided with a tip 40, the diameter of the t...

Embodiment 3

[0042] Such as Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the vertical rod 14 includes an upper connecting rod 16 and a lower connecting rod 17, and the cross-sectional shape of the upper connecting rod 16 is polygonal, such as a triangle, a quadrilateral or a pentagon. , Or as Image 6 As shown in the spline shape, the lower connecting rod 17 is a hollow tube, and the shape of the inner hole of the lower connecting rod 17 is consistent with that of the upper connecting rod 16. The upper connecting rod 16 is inserted in the lower connecting rod 17, outside the lower connecting rod 17. A third mounting hole 35 is opened on the circumferential surface, and a threaded jack 36 is installed in the third mounting hole 35. The upper connecting rod 16 is tightened and loosened by the threaded jack 36 to realize the upper connecting rod 16 and the lower connecting rod 16 The tightening and loosening between the rods 17 thereby adjust the length of...

Abstract

The invention relates to a vertical double-electric-torque wrench which is applied to dismounting and mounting a connection bolt of a steel rail of a railway. The vertical double-electric-torque wrench comprises a shell, a power output assembly and a sleeve, wherein the power output assembly is arranged in the shell and comprises at least one battery and a motor, the battery and the motor are connected, an output shaft of the lower end of the motor is in transmission connection with the sleeve, a vertical rod is fixedly arranged at the upper end of the shell, an axial line of the vertical rod is superposed with an axial line of the output shaft of the motor, and the upper end of the vertical rod is provided with a vertical operation handle. The vertical double-electric-torque wrench disclosed by the invention is provided with the vertical rod, and an operator does not need to squat and stoop to dismounting and mounting the bolts arranged on a sleeper of the steel rail, so that the labor intensity of the operator can be reduced, and the problem of the operator is easy to tired is solved.

Description

Technical field [0001] The invention relates to an electric torque wrench, in particular to a vertical double electric torque wrench used for disassembly and assembly of rail connecting bolts. Background technique [0002] Torque wrenches are commonly used tools for tightening nuts, bolts and other fasteners. The disassembly and assembly of the connecting bolts between railway rails and between rails and sleepers are now mainly internal combustion engine torque wrenches or hand-held electric torque wrenches. Internal combustion engine torque wrenches are heavy, up to 70Kg, and need to be transported to the construction site by transport vehicles. , Requires at least two people to operate, and requires a high level of technical operation, and the labor cost is high. The prior art internal combustion engine wrench can only be used to disassemble the bolts installed vertically on the sleeper, and cannot be used to disassemble the rail connecting plate Horizontally fixed bolts. The...
