Description

An R-type spring pin impact pin puller

technical field

The utility model relates to a pin pulling tool, in particular to an R-shaped spring pin impact pin puller. the

Background technique

High-voltage transmission line insulators are mainly composed of porcelain umbrella skirts, steel caps, and steel feet. R pins are installed inside the steel caps. When the insulator is connected to the insulator and the connection between the insulator and the fitting, the R pin in the bowl head is first pulled out partly, and the ball head of the steel foot part is put into the bowl head of the steel cap part, and then the R pin is pushed into the bowl head. Can. the

During operation, insulators will often be damaged due to external force damage or other reasons. During regular inspections, some insulators will also be found to have zero values. Unqualified insulators found must be replaced in time. To replace the insulator, the R pin in the bowl head of the insulator must be pulled out before replacement can be performed. Due to the umbrella-shaped appearance of the insulator, general tools are not easy to operate, and the R pin is hard, so a special pin puller must be used for operation. the

The currently purchased insulator pin puller is more practical for insulators of 160kN and below, and the designed curvature, moment arm and fulcrum are more suitable. For example, CN201220216127.3 discloses a special pin pulling tool for R-type pins of power transmission lines, which is characterized in that it includes bowl head tentacles, pin pulling hooks, return springs, handles, pull rod fixing screws and handles, and the front end of the handle is provided with The bowl head tentacles and the handle are fixed inside the handle through the pull rod fixing screw, the top of the pull rod fixing screw is provided with a pull pin hook, and the front part of the pull rod fixing screw is provided with a return spring. Its weak point is: 1) the pulling out of R type pin is time-consuming and laborious. 2) For insulators of 240kN and above for the above tool, due to the enlarged shed, depth, and steel cap, the length of the R pin also increases, and the angle between the hook at the front end of the pin puller and the fulcrum cannot pull out the R pin smoothly. Especially in recent years, with the large number of JL/G630/45 steel-cored aluminum stranded wires used in the transmission line conductor models, JL/G2A-900/75, JL/G2A-1000/80 type steel wires are also used in the ultra-high line DC lines For aluminum-core stranded wire, the cross-section of the conductor increases, which directly leads to an increase in the construction and operating tension of the conductor, and the tonnage of the insulator also increases to 300kN, 420kN, 550kN and other models. Therefore above-mentioned tool can't satisfy the needs of construction and overhaul. 3) The above tools cannot correct the deformed R-type pin, and cannot install the R-type pin. 4) The function is relatively single, and the bolts on the insulator accessories cannot be removed. 5) Only one type of R-type pin can be removed. the
