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

[0030]A portable short-circuit grounding device, comprising a grip bar 1, a chuck connection device 2, a chuck 3, an adjustment rod 4, a support cable device 34, and an electric control system; section 45 and tail section 46; the section diameter of the head section 45 is smaller than the section diameter of the tail section 46; the head section 45 and the tail section 46 are hollow; the head section 45 is inserted into the tail section 46; The position where the head section 45 and the tail section 46 are sleeved is provided with a telescopic limiter 47; the rear part of the grip bar 1 is provided with an indicator light and a button area 6, and the middle part is provided with a groove-28; the groove-28 A clamping block device 7 is provided inside; the end of the handle bar 1 is connected to the chuck connection device 2; the top of the chuck connection device 2 is provided with a bump 36, and the bump 36 is connected to the adjustment long rod 4; A collet 3 is fixed below t...

Embodiment 2

[0037] 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

[0039] 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.

One end of the clamping head connecting device is connected to the clamping head, and the other end is hinged to the adjusting long rod. The clamping head mainly includes a clamping seat and a movable clamping block, the movable clamping block is provided with a motor and a threaded sliding block, the inner surface of the right sideof the clamping seat is provided with sliding teeth, and the threaded sliding block is engaged with the sliding teeth. The front side of the clamping seat is provided with a clamping wire sensing device, the holding rod is provided with a clamping block device, an indicating lamp and a button area, and the motor, the clamping wire sensing device, the indicating lamp and the button area are connected to the electrical control system. The portable short-circuit grounding device can adapt to the short-circuit grounding clamping of wires of different specifications, the length can be freely adjusted, the device is convenient to carry, the operation is simple and convenient, and the device is safe and labor-saving.

Description

technical field [0001] The invention belongs to the technical field of electric power safety maintenance, and relates to a portable short-circuit grounding device. 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. The short-circui...
