Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic drive mechanisms, and particularly relates to a hydraulic drive mechanism. Background Art

[0002] A hydraulic drive mechanism is composed of components such as a hydraulic pump, a hydraulic cylinder, a hydraulic motor, a control valve, an oil tank, and pipelines. It is a system that transmits power and motion through the pressure and flow rate of hydraulic oil. It is widely used in various mechanical equipment, such as excavators, hydraulic cranes, numerical control machine tools, etc. Its main advantages include large output force, smooth movement, fast response speed, and easy implementation of automatic control, etc.

[0003] During the maintenance work of a mine shaft opening, it is necessary to build a maintenance platform. Maintenance personnel can perform maintenance on the shaft opening on the built platform. However, the method of temporarily building the platform will take a long time, be time-consuming and laborious. It not only increases the workload of the maintenance personnel, but also has an adverse impact on the progress of the maintenance work. Based on these problems, Chinese Patent CN220101681U discloses a hydraulic drive mechanism for a maintenance platform. Through the designed hydraulic cylinder and hydraulic rod, it can provide the power for the opening and closing of the cover plate, and uses a connecting plate, a connecting structure and a fixing structure to connect the cover plate and the hydraulic rod. When maintenance is required, the cover plate can be automatically closed to form a maintenance platform. The advantage of this design is that there is no need to build the platform manually, which saves time and effort and is conducive to the smooth progress of the maintenance work.

[0004] The hydraulic cylinder in this hydraulic drive mechanism is not fixed together with the guide rail assembly. Therefore, the hydraulic cylinder and the guide rail assembly in this hydraulic drive mechanism need to be installed separately in sequence. This process not only wastes the time of the staff, but also hinders the normal installation of the hydraulic cylinder due to the uneven terrain. Summary of the Utility Model
