The invention discloses a high-voltage line card maintenance assembly pliers, which comprises a fixed handle, a movable handle, a roller installation rod, a pull rod hook, a connecting rod, a driving rod, a pressing rod, an active connecting plate, a first pin sleeve and a second pin sleeve, the The above-mentioned roller mounting rod is connected between the fixed handle and the movable handle, and the above-mentioned pull rod hook is installed inside the upper end of the fixed handle and protrudes from the front end of the fixed handle, and the above-mentioned roller mounting rod is connected with the pull rod hook through a connecting rod , the playing rod is installed at the front end of the movable handle. Through the above method, the operator holds the fixed handle and the movable handle, and pulls the pull rod hook through the roller installation rod and the connecting rod. Under the action of the shaped groove, the active connecting plate rotates around the second pin sleeve, the active connecting plate rotates around the first pin sleeve by driving the pressing rod, and the pressing rod drives the driving rod to press down the pin, which greatly facilitates the installation after maintenance and improves the efficiency.
Description
technical field [0001] The invention relates to the field of assembly pliers, in particular to an assembly pliers for maintenance of high-voltage wire clamps. Background technique [0002] After the high-voltage line card of the domestic power grid is used for a period of time, in order to ensure good contact and good conductivity, it is necessary to replace the silver-coated copper plate. Because the red copper pressing plate coated with silver on both sides is tightened by the tension of spring (extension spring) through two cylindrical pins, and the tension reaches 25 kg. The line card design and size have been finalized and cannot be changed. During the maintenance and installation process, it was found that after the cylindrical pin was installed on one side, the tension spring only left a small gap on the other side, which made the installation extremely inconvenient and the operation extremely difficult. Contents of the invention [0003] The main technical proble...
