Problems solved by technology

The short-circuit grounding device provided in the prior art has an oblique angle between the clip and the wire when clamping the wire, which makes it difficult to clamp the wire, and limited by the structure of the chuck, it can only clamp a certain cross-section type of wire, and its compatibility is poor
The short-circuit grounding operation sometimes requires high-altitude operations. The operator clamps the wire with the short-circuit grounding device. Due to the angle problem, it is often difficult to judge whether the wire is clamped or not.
In case of wires that are difficult to clamp, the operator will easily cause fatigue when holding the short-circuit grounding device for a long time, and manpower is required to control the chuck to close and clamp the wire, which increases the difficulty of operation

Embodiment 1

[0027]A short-circuit grounding device that is convenient to use, including a grip bar 1, a chuck connection device 2, a chuck 3, a connecting adjustment rod 4, a support cable device 34 and an electric control system; the tail of the grip bar 1 is provided with an indicator light and The button area 6 is provided with a groove one 28 in the middle, and a block device 7 is arranged in the groove one 28; the end of the handle bar 1 is connected to the clamp connecting device 2; the top of the clamp connecting device 2 is provided with Protrusion 36, the protrusion 36 is connected to the adjustment long rod 4; the collet 3 is fixed under the collet connection device 2; the collet 3 includes a clamp seat 8, a movable clamp block 9 and a clamping induction device 13; The right side of the movable clamp block 9 is provided with a groove two 14; a motor 15 is fixed on the inner side upper surface of the groove two 14; the rotor of the motor 15 is connected with a threaded sliding blo...

Embodiment 2

[0034] The second embodiment is basically the same in structure and principle as the first embodiment, except that the block device 7 includes a block 29 , a hand protrusion 30 and a spring 2 31 ; the hand protrusion 30 is arranged on the top of the block 29 . Through the handle protrusion 30, the locking block 29 can be easily turned up.

Embodiment 3

[0036] The structure and principle of this embodiment 3 are basically the same as that of embodiment 1, the difference is that the clamping tooth 20 is provided on the clamping surface of the movable clamp block 9, and the clamping tooth 20 is provided on the clamping surface of the clamp base 8. Two clamping teeth 21. The protrusions and depressions of the clamping tooth one 20 correspond to the depressions and protrusions of the clamping tooth two 21 one by one, so that the clamping of the wire is more stable.

Description

technical field [0001] The invention belongs to the technical field of electric power safety maintenance, and relates to a short-circuit grounding device which is convenient to use. Background technique [0002] At present, it is necessary to temporarily ground the power equipment that has been powered off when performing maintenance on high-voltage power equipment. Inductive electric influence, to avoid electric shock accidents caused by maintenance operators. Circuit grounding is a necessary safety technical measure for turning electrical equipment from the running state to the maintenance state, and a special short-circuit grounding device is required for operation. The short-circuit grounding device provided in the prior art has an oblique angle between the clamp and the wire when clamping the wire, which makes it difficult to clamp the wire, and limited by the structure of the clamp, it can only clamp a certain cross-section type of wire, and its compatibility is poor....
