Embodiment 1

[0033] Such as Figure 2-5As shown, the middle rotating short-circuit grounding device of the present invention includes a wire end clamp A and a handle 7. The wire end clamp A includes a pair of splints 1 connected by a support piece 8 to a steering shaft and provided with an arc-shaped engagement 2 on the upper part. The support piece 8 rotates through the rotating shaft 9; the tail part A of the wire terminal clamp is provided with a pair of modules 3, and the pair of modules 3 is provided with a movable nut 4, and the movable nut 4 is connected with the movable piece 5 arranged on the pair of modules 3 by a screw rod, and the movable The nut 4 can rotate horizontally along the screw rod, and the movable piece 5 can slide on the pair of modules 3; The rotary connection is arranged inside the cover tube 6.2 and is connected with a pair of telescopic rods 6.1, wherein, a pair of telescopic rods 6.1 are threaded, and are respectively threaded with respective matching movable n...

Embodiment 2

[0037] The difference from Example 1 is that the inner side wall of the splint 1 is also provided with a depressing tongue 10, which is arranged between the rotating shaft 9 and the arc-shaped bite 2, and the other splint 1 is correspondingly provided with a tongue depressing through hole. . The function of the depressing tongue 10 is that when the wire end clamp A is in an open state, the depressing tongue 10 is used to prop up the wire end clamp A to avoid moving back and forth when the telescopic rod 6.1 is tightened. When it is necessary to loosen the splint 1 for clamping, the pressing tongue 10 contacts the wire, and the wire end clamp A can be released. The remaining technical principles are the same as in Embodiment 1.

Embodiment 3

[0039] The difference from embodiment 1 is that the rotating rod 6.3 is threaded as a whole, and the rest of the operation methods are the same as in embodiment 1.

Abstract

The invention discloses a screw drive-type middle rotating-type short circuit grounding device comprising a wire end terminal and a handle rod. The wire end terminal comprises a pair of clamp plates which rotatably connected through a rotating shaft. Arc clamping portions are formed on the clamping plates. Matched die blocks are arranged at the tail of the wire end terminal and provided with movable nuts. The movable nuts are connected with movable plates of the matched die blocks through screws and capable of horizontally rotating and sliding on the matched die blocks. The movable plates slide on the matched die blocks. A telescopic mechanism is further provided and comprises a pair of telescopic rods, a cover cylinder, a rotating rod and a linkage rod. The linkage rod is rotatably linked with the inside of the cover cylinder and the telescopic rods. The telescopic rods are provided with threads and in screw connection with the matched movable nuts 4 respectively. The screw drive-type middle rotating-type short circuit grounding device is high in safety, the wire end terminal is manually controlled to clamp or loosen the wire, and accordingly the wire end terminal never automatically falls.

Description

technical field [0001] This application is a divisional application of the invention patent application with the application number 201210548535.3 and the application date is December 18, 2012, and the invention name is "middle section rotating short-circuit grounding device". Background technique [0002] In existing short-circuit grounding devices, such as figure 1 The grounding wire 100 shown is a safety tool used to temporarily ground the power equipment that has been powered off when the power equipment is overhauled. The induced electric impact generated to prevent the occurrence of electric shock accidents for staff. Installing a grounding wire is a necessary safety technical measure to change the power equipment from the operating state to the maintenance state. The grounding wire 100 is connected to the wire and the earth by means of the wire end wire clamp 200 and the grounding end wire clamp 300 respectively. However, in the prior art The wire end clamp includes...
