Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, specifically a hydraulic support for mine shafts. Background Technology

[0002] Hydraulic supports are important mechanical equipment used in underground coal mines, mainly for supporting and protecting the coal mining face. Their specific structure includes a base arranged on the roadway surface, a hydraulic lifting device mounted on the base, and a support platform on top of the lifting device. In use, the base is moved to the required position, the hydraulic lifting device is raised, and the support platform is placed under the surrounding rock at the top of the roadway to prevent the surrounding rock from settling and to block the broken and falling parts of the surrounding rock. At the same time, it can control the mine pressure and distribute the pressure to various parts of the support to ensure the stability of the coal mining face.

[0003] As the coal mining face advances, the hydraulic supports need to be moved in a timely manner. The usual method of moving the supports is to connect the base of the hydraulic supports to the coal mining machine. As the coal mining machine advances, it drives the hydraulic supports to move. In order to reduce the pressure on the roadway surface, the bottom surface of the coal mining support base is flat. Therefore, the hydraulic supports are dragged during the moving process.

[0004] The following problems exist during the relocation process: it is usually required that there are no residual coal or rocks on the top support surface of the hydraulic support during the relocation, but the height space of the roadway is limited, making it inconvenient for workers to clean.

[0005] Chinese patent discloses a hydraulic support for coal mines (authorization announcement number CN221973562U). This patented technology uses a lifting structure to lift the base of the hydraulic support forward and upward, so that the front end of the base is removed from the pit. At the same time, the overall center of gravity shifts after lifting, causing the front end of the hydraulic support to fall to the outside of the pit, and then the hydraulic support moves forward as a whole. Repeating this step can gradually move the hydraulic support out of the pit, so that the hydraulic support can be moved normally and smoothly.

[0006] At the same time, when the lifting structure is raised, the support surface on the hydraulic support tilts, and the gravel and coal on it roll off, eliminating or reducing the need for manual cleaning. The structure is ingeniously designed, provides good support, and is stable in terms of overall stress and pressure on the ground.

[0007] However, it has certain drawbacks: it allows loose gravel to slide off by its own weight by adjusting the posture of the support platform, but it is almost ineffective against stubborn debris (such as caking coal slag and rock fragments embedded in the cracks) and dust layers that are adhered to the surface of the support platform due to moisture, oil stains or mechanical compression. Furthermore, when there is a lot of accumulated gravel and dust, adjusting the posture of the support platform alone is not enough to achieve a good cleaning effect. Therefore, in actual operation, manual secondary sweeping is still required, which is not only inefficient, but also forces personnel to frequently work under the roof of narrow roadways, facing major safety hazards such as roof collapse and side fall.

The entire cleaning process is fully automated, requiring no manual operation, and the cleaning effect is good. The powerful airflow can remove most of the gravel and dust.
