In order to meet the aim, the utility model adopts the following technical scheme:
The utility model provides a special dolly of heavy crown block board hook round pin axle dismouting of steelmaking, includes the automobile body, the automobile body below is equipped with the wheel, the automobile body top is equipped with the regulation support, be equipped with the steel pipe on the regulation support, be equipped with the ram in the steel pipe, the one end of steel pipe is equipped with the flange, be equipped with fixing bolt on the flange, fixing bolt and crown block board hook phase-match connection.
Preferably, long grooves are formed in two sides of the steel pipe, hammer handles are arranged on two sides of the hammer, the hammer handles are arranged on two sides of the hammer through the long grooves in the steel pipe, and front hammer limit and rear hammer limit are arranged at two ends of the long grooves.
Preferably, a slide way is arranged in the steel pipe, and the ram is arranged on the slide way in the steel pipe.
Preferably, the adjusting support is an adjustable lifting support.
The beneficial effects of the utility model are as follows:
(1) According to the utility model, the trolley special for disassembling and assembling the plate hook pin shaft and the plate hook ear plate are fixed integrally, the ram in the trolley special for disassembling and assembling the plate hook pin shaft is fully utilized to move from left to right at high speed, and the ram moving at high speed impacts the plate hook pin shaft, so that the pin shaft is ejected out repeatedly for several times.
(2) When the special trolley for disassembling and assembling the plate hook pin shaft of the steelmaking metallurgy crown block is used, the plate hook pin shaft is disassembled, the collision process is controllable, the operation is strong, the accident of hurting people can not occur, and the safety and the reliability are realized. In the conventional operation mode, in the process of hammering the pin shaft by personnel, because the mass ratio of the large hammer to the pin shaft is small, the impact effect is greatly influenced by the difference of the swinging skills of the large hammer by the operating personnel, and the hammering efficiency is low. The special trolley mode is adopted to knock out the pin shaft, so that the defects of the conventional operation mode are avoided.
(3) The special trolley for disassembling and assembling the plate hook pin shaft of the steelmaking metallurgical crown block reduces the labor intensity of operators, shortens the working period by 50 percent and obviously improves the labor productivity.
