Embodiment Construction

[0027] A hydraulic station 2 is installed on the lower part of one side of the body 1, and a control room 3 is arranged on the upper part. A push-pull cylinder 4 in the Y direction is installed on one side of the body 1. The push-pull cylinder 4 in the Y direction and the push-pull cylinder 6 in the X direction pass through the ejector rod. 5 installation, the push-pull cylinder 6 placed horizontally in the X direction is connected to the vertical jacking cylinder 8 through the mounting ear 7.1 of the connecting part 7.

[0028] In order to improve the stability of the equipment after repair and ensure the production progress, the solution adopted is to replace the driving wheel connecting rod and related bearings to allow the driving wheel connecting rod to complete the driving work; to replace the oil cylinder seal and explosion-proof valve group so that the hydraulic cylinder can perform the descending action smoothly .

Abstract

The invention proposes a maintenance method for a marine hydraulic jacking device. Repair process: Including the hydraulic system, replace all damaged valve groups. Reset and install the oil tank of the hydraulic station, and replace the high-pressure retaining ring and high-pressure sealing ring at the joint after the pipeline is disassembled. Replace the damaged high and low pressure oil pipes. Maintenance of traveling mechanism and jacking mechanism. The present invention takes maintenance measures after analyzing the system failure of the hydraulic jacking device, so that the integrity rate of the hydraulic jacking device can be guaranteed, and the hydraulic jacking device can operate safely and without failure. It is suitable for application as a method for repairing failures of hydraulic jacking devices.

Description

technical field [0001] The invention proposes a maintenance method for equipment faults in the mechanical field, specifically a maintenance method for a marine hydraulic jacking device. Background technique [0002] Ports and wharves have a large demand for the frequent application of jacking devices. According to the actual working conditions of the company, the use of this type of equipment in each branch factory is facing aging to varying degrees, and there are many failures. Considering the production progress, it is often It is a minor illness and minor repair. When the equipment fails to operate, it has to be shut down. In fact, this kind of equipment usage is quite detrimental to the service life of the equipment. [0003] The damage of the oil cylinder is reflected in the serious damage or aging of the pump unit, seal, and stop valve, which leads to the bending of the connecting rod and the failure to complete the normal driving work.
