Description

Multipurpose hydraulic pliers

technical field

The utility model belongs to the technical field of tools, and in particular relates to a tool suitable for replacing cross-arm screws of electric high-voltage lines and low-voltage lines and crimping cables.

Background technique

At present, when replacing the cross-arm of the high-voltage line and low-voltage line of the electric power, the screws of the cross-arm are corroded due to the wind and rain for many years, and it is difficult to remove them. The time is long, and it is easy to prolong the shortcoming of power failure time. In addition, when crimping the terminal clips, in the case of high-altitude operations, only pliers can be used to crimp, the crimping is not firm, and it is easy to cause poor contact. In view of this situation, we have developed Multi-purpose hydraulic tongs overcome many shortcomings of previous traditions.

Contents of the invention

The purpose of this utility model is to provide a kind of fast hydraulic clamp device in order to overcome the above-mentioned disadvantages, realize the utility model

The technical solution adopted for the purpose of the model is: a multi-purpose hydraulic pliers, including a hydraulic cylinder, a hydraulic cylinder rod and a hydraulic handle, characterized in that: the front end of the hydraulic cylinder is fixed with a pliers head, and the rear end of the hydraulic cylinder is provided with a handle. There is an upper mold groove on the head of the pliers, and a lower mold groove is arranged at the end of the hydraulic cylinder rod opposite to the upper mold groove. In the upper mold groove, there is an upper mold that combines the upper pressing knife and the upper plate teeth. In the lower mold groove, there is a lower mold groove. The lower die combined with the pressing knife and the lower teeth. In addition, it is equipped with solid screws to cooperate with the upper mold. the

The utility model can quickly cut off the screw, conveniently crimp the wire clamp, effectively reduce the labor intensity of the staff, and can also greatly improve the work efficiency at the same time. the

Detailed ways

Referring to the accompanying drawings, a multi-purpose hydraulic pliers, including a hydraulic cylinder 1, a hydraulic cylinder rod 2 and a hydraulic handle 3, is characterized in that: the front end of the hydraulic cylinder 1 is fixed with a pliers head 4, and the rear end of the hydraulic cylinder 1 is provided with a handle 5 , the pliers head 4 is provided with an upper mold groove 6, and the end of the hydraulic cylinder rod 2 opposite to the upper mold groove 6 is provided with a lower mold groove 7, and the upper mold groove 6 is provided with an upper pressing knife 8 and an upper plate tooth 9 compounded Mold 10, the lower mold 13 that is provided with lower pressing knife 11 and lower plate teeth 12 composites in lower mold groove 7. Cooperate with upper mold 10 to be provided with solid screw 14 in addition. the

During use, if the screw on the cross arm is corroded and difficult to remove, place the screw between the upper pressing knife 8 and the lower pressing knife 11 in the utility model, adjust the hydraulic handle 3 to push the hydraulic cylinder rod out and push The lower pressing knife 11 is pressed upwards and the upper pressing knife 8 is closed, and the screw is cut off under the action of pressure for replacement. If the clamp is crimped, put a copper lug on the end of the cable, place it between the upper teeth 9 and the lower teeth 12, adjust the hydraulic handle 3 to push out the hydraulic cylinder rod and push the lower teeth 12 to close the upper teeth 9 , crimp the clamp firmly.
