Auxiliary trolley for rapidly replacing motor and hydraulic pump of hydraulic station

Abstract

An auxiliary trolley for rapidly replacing a motor and a hydraulic pump of a hydraulic station comprises a base, a bracket, two supporting legs, two pulling rods and a lifting hook. Wheels are installed under the base. The bracket is fixed in a right-angle ruler shape through a cross beam and a longitudinal beam. The lower end of the longitudinal beam is perpendicularly fixed to the upper surface of the base. The two edges adjacent to the edge, where the bracket is fixed, of the base are provided with grooves penetrating through the thickness of the base correspondingly. The supporting legs are in inverted U shapes. Each supporting leg is hinged to the corresponding groove through the free end of a U-shaped arm of the supporting leg. The plane of the two supporting legs is parallel to that of the bracket after hinging. The U-shaped bottoms of the supporting legs are provided with supporting leg grooves penetrating through the thickness of the U-shaped bottoms. The lower ends of the two pulling rods are fixed to the grooves correspondingly. When the supporting legs rotate to the U-shaped bottoms along the hinge points and are in horizontal states, the upper ends of the pulling rods penetrate through the supporting leg grooves of the two supporting legs correspondingly, and the upper portions of the pulling rods are connected with nuts. A guide rail is arranged on the cross beam of the bracket. Rolling wheels are installed on the upper portion of the lifting hook. The lifting hook is connected to the guide rail on the cross beam of the bracket in a rolling mode through the rolling wheels. According to the auxiliary trolley for rapidly replacing the motor and the hydraulic pump of the hydraulic station, the motor or the pump can be rapidly replaced in a narrow space.

Description

technical field [0001] The invention relates to a trolley, in particular to an auxiliary trolley for quickly replacing a hydraulic station motor and a hydraulic pump. Background technique [0002] In the cold rolling production of metallurgical enterprises, a large number of hydraulic systems such as HGC reduction, CVC roll shifting system, bending roll and wedge adjustment system, etc. are widely used; due to the extensive use of hydraulic lubrication systems, many hydraulic stations and lubrication stations need to be configured. Take the second cooling of Handan Iron and Steel as an example: the whole plant needs 20 hydraulic stations and about 10 lubrication stations. During the long-term use of these hydraulic lubrication stations, the hydraulic pumps, motors and coupling pads need to be replaced regularly. The motor must be disassembled and assembled more than 5 times a month. Due to the large power and heavy weight of the motors of these hydraulic stations and lubric...

AI Technical Summary

Problems solved by technology

Due to the large power and heavy weight of the motors of these hydraulic stations and lubrication stations, and the small space of the hydraulic lubrication stations, it takes time and effort to move, disassemble or install the motors and hydraulic pumps, waste a lot of manpower and maintenance time, and seriously affect normal production
