Description

Technical Field

[0001] The present application relates to the technical field of hydraulic support for coal mines, and in particular to an automatic measurement system for hydraulic support equipment for coal mines. Background Art

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. Underground coal mines require tunnels to be dug underground to mine coal. The scope of coal mines includes a large area above ground, underground and related facilities.

[0003] Usually, after mining, coal mines will leave a mine opening. To prevent collapse, hydraulic support equipment is needed for support and protection. Hydraulic support equipment is generally a hydraulic support, which consists of a hydraulic cylinder, a bearing structure, a push device, a control system and other auxiliary devices. The support is provided by the combined force of the supporting parts of the hydraulic support and the roof.

[0004] However, the existing hydraulic support equipment needs to be tested, including pressure testing, instrument observation, record registration, data preservation, and quality judgment. Not only does it require a large number of workers to participate, but the test results are also directly related to the workers' experience. As the hydraulic support equipment is under the action of gravity at the mine mouth, the support length, height and other directions of the hydraulic support equipment will change. If the staff cannot detect the change in support distance in time, even after discovering the change in support distance, it will still take a long time to measure, which may easily cause the support distance to reach the safety critical point and easily cause safety hazards. Summary of the invention

[0005] In order to promptly detect changes in support distance and quickly repair hydraulic support equipment, the present application provides an automatic measurement system for hydraulic support equipment for coal mines.

[0007] By adopting the above technical solution, when the hydraulic support equipment is installed, the first connecting member is parallel to the top of the hydraulic support equipment, and the first connecting member is located between the top of the mine tunnel and the hydraulic support equipment, so that the top of the hydraulic support equipment is arranged in parallel in the mine tunnel. Since the first detection member can detect the parallelism between the first connecting member and the hydraulic support equipment, when the hydraulic support equipment tilts under the gravity of the mine tunnel, the hydraulic support equipment needs to be repaired and the mine tunnel sinking data is calculated by the inclination; similarly, the second detection member can detect the verticality between the second connecting member and the hydraulic support equipment, and then it can be calculated whether the hydraulic support equipment on the second connecting member has a lateral displacement and an angle tilt. The third detection member can also detect the tilt or displacement of the first connecting member toward the direction of the third connecting member, and the shape change of the support triangle formed by the hydraulic support equipment is analyzed by the three-point force point, so as to obtain an adjustment plan for the hydraulic support equipment, so as to timely discover the change of the support distance and quickly repair the hydraulic support equipment.

[0008] Optionally, the first connecting member includes a top plate, a first abutment frame and a first reinforcement frame, the top plate is arranged on the top of the hydraulic support equipment, the first abutment frame is arranged at an end of the top plate away from the hydraulic support equipment, the first reinforcement frame is arranged at an end of the first abutment frame away from the top plate, and the first reinforcement frame is used to fill the gap between the first abutment frame and the mine tunnel; the hydraulic support equipment includes a cross beam arranged on the top, the cross beam abuts against the top plate and is parallel to each other.

[0009] By adopting the above technical solution, when installing the hydraulic support equipment, the top plate, the first abutment frame and the first reinforcement frame are placed on the top of the beam of the hydraulic support equipment from bottom to top in sequence. The first reinforcement frame is made of flexible material, which increases the friction between the first abutment frame and the top of the mine tunnel, and can facilitate the adjustment of the first abutment frame and the top plate to a state parallel to the beam at the top of the hydraulic support equipment.

In order to reduce the possibility of the first detector being crushed, the first detector can slide with the installation box, and the first elastic member enables the first detector to maintain abutment with the first abutment member and maintain a warning state. The receiving block is provided to reduce the possibility of the first receiving block falling and abutting with the first detector under the action of gravity. When the receiving block is subjected to a pressure exceeding the safe range, it separates from the top plate and falls.

[0017] By adopting the above technical solution, the side plate, the second abutment frame and the second reinforcement frame are placed on the ends of the top plate and the leveling plate from left to right in sequence. The second reinforcement frame is also made of flexible material, which increases the friction between the second abutment frame and the side wall of the mine tunnel and facilitates adjusting the second abutment frame, the top plate and the leveling plate to a vertical state.

[0018] Optionally, the third detection member includes a mounting column, a mounting block, a third detector and a positioning member, the mounting column is obliquely arranged between the top plate and the side plate, the mounting block is arranged on a side of the mounting column close to the side plate, the mounting block is slidably connected to the side plate, a positioning member is provided on the mounting block, the positioning member is used to fix the mounting block on the side plate, the third detector is arranged at one end of the mounting column close to the top plate, and the third detector is used to detect the verticality between the top plate and the side plate.
