Auxiliary crank arm device for moving diesel generator in workshop

Abstract

The invention relates to an auxiliary crank arm device for moving a diesel generator in a workshop, which comprises a base, a vertical support frame and a cross beam, the lower end of the vertical support frame is connected to the base, the upper end of the vertical support frame is connected with the cross beam, the cross beam extends downwards to form a connecting block, and a pin hole is formed in the connecting block. The four auxiliary crank arm devices are installed at the four corners of the diesel generator, the lifting lugs at the four corners of the diesel generator are connected with the pin holes through the pins, the hydraulic jack is arranged below the base, and the auxiliary crank arm devices and the diesel generator are lifted together through the hydraulic jack. And therefore, the diesel generator can be moved to the sliding rail after being jacked, and the diesel generator can be conveniently moved out of the workshop subsequently. The auxiliary crank arm device is formed by welding the steel plates, the structure is simple and stable, the diesel generator with the weight of 30 tons can be borne, use is convenient and fast, and the diesel generator in a plant can be conveniently moved.

Description

technical field [0001] The invention relates to an auxiliary device for a mobile diesel generator, in particular to an auxiliary crank arm device for a mobile diesel generator in a workshop. Background technique [0002] The first phase of Shandong Haiyang Nuclear Power Plant has 2 units, and there are 4 spare diesel generators on site. If the diesel generator fails and cannot be repaired on site, it needs to be returned to the factory for repair, so the diesel generator must be disassembled. In nuclear power plants, diesel generators are generally stored in the factory building. The space of the factory building is small, and the diesel generator equipment is relatively large. At the same time, there is no design for driving in the factory building of general nuclear power plants. In addition, diesel generators used in nuclear power plants generally weigh up to 30 tons. However, the load on the lifting point above the diesel generator is only 2 tons. Not feasible. Conten...
