Description

Electric hydraulic wheel puller Technical Field The utility model relates to the field of wheel pullers, in particular to an electro-hydraulic wheel puller. Background In the process of equipment maintenance or replacement, a worker often needs to detach a belt pulley, a gear or other rotating parts from a motor shaft, smoothly and safely detach the rotating parts from the motor, and conventionally, when pulling out the wheel, the rotating parts are usually pried by using tools such as a wrench manually to separate the rotating parts from the motor shaft. In the current maintenance workshop, a relatively common wheel pulling mode generally requires 2-3 people to use tools such as a wrench in a matching manner to pull wheels, and operators are required to apply larger physical force, so that the efficiency of pulling wheels in the workshop is reduced while muscle fatigue damage is easily caused. Therefore, for the wheel pulling device by using tools such as a wrench manually, an electric hydraulic wheel pulling device can be designed, and the wheel pulling device is set to be driven by electric hydraulic pressure, so that the traditional manual wheel pulling mode is abandoned, and the problem is solved conveniently. Disclosure of utility model In order to overcome the problems that in the existing maintenance workshop, a relatively common wheel pulling mode is generally required to be carried out by 2-3 persons in cooperation with tools such as a wrench, and an operator is required to apply a relatively large physical force, so that muscle fatigue damage is easily caused, and meanwhile, the efficiency of wheel pulling in the workshop is also reduced.
