Maintenance auxiliary equipment for large hydraulic cylinder

Abstract

The invention provides maintenance auxiliary equipment for a large hydraulic cylinder. The maintenance auxiliary equipment comprises a base and self-locking universal wheels. A lifting table is fixed to the upper surface of the base. The self-locking universal wheels are symmetrically fixed to the bottom of the base. A turnover device is fixed to the top of the lifting table. A translation stretching device is fixed to the upper end of the turnover device. According to the maintenance auxiliary equipment, the turnover device is driven by the lifting table to ascend and descend, the angle is adjusted through the turnover device, the length is adjusted through the translation stretching device, a first clamping device and a second clamping device are driven to move to proper positions, the oil cylinder to be maintained is clamped, and people can safely disassemble the oil cylinder; the oil cylinder can be rotated through the first clamping device and the second clamping device, and the maintenance auxiliary equipment can be conveniently matched with maintenance personnel for work; a piston rod of the oil cylinder can be pulled out through the translation stretching device, the piston rod is pulled out stably, and damage to the oil cylinder is relieved; and by adjusting the height of a second clamping roller, the maintenance auxiliary equipment can adapt to oil cylinders in different diameters.

Description

technical field [0001] The invention relates to the technical field of hydraulic equipment, in particular to a maintenance auxiliary equipment for a large hydraulic cylinder. Background technique [0002] Hydraulic equipment is a device that transmits pressure through hydraulic oil. Hydraulic equipment is the carrier of the hydraulic system. A complete hydraulic system consists of five parts, namely power components, actuators, control components, auxiliary components and hydraulic oil. Hydraulic equipment is a combination of parts. Hydraulic equipment has a large transmission force, is easy to transmit and configure, and is widely used in industrial and civil industries. The function of hydraulic cylinder and hydraulic motor, the actuators of the hydraulic system, is to convert the pressure energy of the liquid into mechanical energy to obtain the required linear reciprocating motion or rotary motion. According to the action you want to design, you can modify the compon...

AI Technical Summary

Problems solved by technology

[0003] In some large-scale hydraulic equipment, hydraulic cylinders are frequently used actuators. When large-scale hydraulic cylinders are damaged, people need to disassemble and repair the hydraulic cylinders. The existing disassembly is assisted by cranes for disassembly, assembly, movement, etc. Operation, during the hoisting process of the crane, it is easy to hurt the maintenance personnel, which is very dangerous, and it is easy to cause damage to the piston rod and other components of the hydraulic cylinder;

[0004] When the hydraulic cylinder is being maintained, it is inconvenient to rotate the hydraulic cylinder, and it is inconvenient to cooperate with the maintenance personnel to work;

[0005] When disassembling the piston rod and casing of the hydraulic cylinder, the piston rod is also pulled by the crane, which is easy to damage the piston rod and casing
