Embodiment 1

[0036] Such as Figure 1-4As shown, the 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 the upper part is provided with an arc-shaped engagement 2. The support piece 8 is a rotating shaft 9 A spring is wound on the top, and the two ends of the spring are against the inner side walls of the two splints 1; the tail A of the wire end clamp is provided with a pairing module 3, and a movable nut 4 is arranged in the pairing module 3, and the movable nut 4 passes through the screw and the setting Connected to the movable piece 5 on the module 3, the movable nut 4 can rotate laterally along the screw rod, and the movable piece 5 can slide on the paired module 3; Side cylinder 6.4, side cylinder 6.4 is hollow, it can expand and contract in the cover cylinder 6.2 through the limit slider 6.6, and will not rotate, the other end of t...

Embodiment 2

[0039] The difference from Embodiment 1 is that the inner side wall of the first 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 depressing tongue 10. Tongue hole. The function of the depressing tongue 10 is that when the wire end clamp A is in the open state, the depressing tongue 10 is used to resist the wire end clamp A, so as to avoid the force of the spring to make the telescopic rod 6.1 move back. 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

[0041] The difference from Embodiment 1 is that the telescopic rod 6.1 and the rotating rod 6.3 are threaded as a whole, and the rest of the operation methods are the same as in Embodiment 1.

Abstract

The invention discloses a short-circuit grounding device, comprising a conductor end wire clamp (A) and a holding rod (7), wherein the conductor end wire clamp (A) comprises a pair of clamping plates (1), wherein the clamping plates (1) are rotationally connected through a rotary shaft; and moreover, the upper parts of the clamping plates (1) are provided with an arc-shaped occlusion (2) respectively. The short-circuit grounding device is characterized in that the tail part of the conductor end wire clamp (A) is provided with a module pair (3); an active screw cap (4) is arranged in the module pair (3); the active screw cap (4) is actively connected with the module pair (3) and further can transversely rotate and slide in the module pair (3); a telescopic mechanism (6) is connected with the active screw cap (4) in a hinging way; the telescopic mechanism (6) is connected with the holding rod (7); and a rotary handle (7.2) capable of controlling the telescopic mechanism (6) to telescope is arranged on the holding rod (7). The short-circuit grounding device has the advantages of high safety performance; and in addition, as the conductor end wire clamp (A) is controlled to tightly clamp or release a conductor by manpower, no automatic dropping of the conductor end wire clamp occurs.

Description

technical field [0001] The invention relates to a safety tool or appliance for overhauling electric power, in particular to a 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 a pair of splints 600 connected by rotation shaft 400 and the upper part is provided with an arc-shaped opening 500 to ...
