Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of shield construction, and particularly relates to a safety auxiliary device for quick installation of a shield machine equipment oil filter shell. BACKGROUND

[0002] As important equipment for modern tunnel construction, a shield machine is a comprehensive device integrating multiple functions, and its interior contains numerous complex mechanical systems and components, and it integrates multiple functions such as excavation, unearthing, support, grouting, and guidance in the construction process. For the shield machine, the construction process is also a process of reasonable use of these functions.

[0003] The shield machine relies on a hydraulic transmission system for transmission to realize the functions of propulsion and excavation, and the hydraulic transmission system is an important power source of the shield machine and is a key system for providing power for main execution elements of the shield machine.

[0004] As a key component of the hydraulic system of the shield machine, the hydraulic oil filter plays a crucial role, and its main function is to filter solid impurities and pollutants in the hydraulic oil through the built-in filter screen to ensure the normal operation of the hydraulic system. The filter generally consists of a shell, a filter core, and a valve core.

[0005] Periodic replacement of the filter core is an important work content in the daily maintenance process of the shield machine to ensure the filtering effect of the filter, prevent damage to the hydraulic system caused by impurities, ensure safe and efficient operation of the shield machine, and make the intact rate and utilization rate of the equipment reach a high level.

[0006] The conventional operation for replacing the filter core is as follows: close the core valve 3 to reduce the pressure, unscrew the filter shell 1, replace the filter core 2, screw back the filter shell 1, and open the core valve 3 to pressurize.

[0007] With the increasing diameter of the shield machine and the increasing power of the system at the present stage, the size of the hydraulic oil filter is also increasing, and the conventional operation of replacing the filter core is gradually becoming dangerous. In the past two years, maintenance personnel have been injured in the hands and feet, and the main reasons are as follows: first, the filter shell is made of steel, has a diameter of 30-40 cm, a height of 60-80 cm, and a weight of 20-30 kg, and the size and weight are large, and 2-3 people need to operate simultaneously; second, the outer surface of the filter is smooth, and it is more slippery if there is oil on the surface; third, there are many devices on the shield machine trolley, and the space is small, which causes great difficulty in the combined efforts of the maintenance personnel, and once a mistake is made, the personnel are easily injured; and fourth, since the filter shell needs to store a certain amount of oil, the shell is generally below the core valve, needs to be installed from the bottom to the top, and the threads are fine and difficult to accurately align the thread port.

[0008] The main means of replacing the shell at present is still the combined installation of 2-3 maintenance personnel, one person holds up with both hands 5, one person fixes with both hands 6, and one person tightens with both hands 7, which has great cooperation risk and consumes long time, and generally needs at least 2 hours.
