Description

Technical Field

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

[0002] A coal mine is an area where humans mine coal resources in coal-rich mining areas, generally divided into underground coal mines and surface coal mines. Underground coal mines need to dig roadways underground to extract coal, and the scope of a coal mine includes a large area above and below the ground and related facilities.

[0003] Generally, after coal mining, a mine opening will be left. To prevent collapse, hydraulic support equipment is required for support and protection. The hydraulic support equipment is generally a hydraulic support, which consists of a hydraulic cylinder, a load-bearing structural member, a pushing device, a control system, and other auxiliary devices, and supports through the combined force of each supporting member of the hydraulic support and the action of the roof.

[0004] When the existing hydraulic support equipment is being detected, in terms of pressure testing, instrument observation, record registration, data storage, and quality judgment, not only are there a large number of workers involved, but also the test results are directly related to the experience of the workers. Under the gravity of the hydraulic support equipment at the mine opening, the hydraulic support equipment will undergo changes in directions such as support length and height. If the staff cannot detect the change in the support distance in time, even after detecting the change in the support distance, it still takes a long time to measure, which is likely to cause the support distance to reach the safety critical point and easily lead to potential safety hazards. Summary of the Invention

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

[0006] The automatic measurement system for coal mine hydraulic support equipment provided by this application adopts the following technical solutions:

The first detection component is arranged at the top of the hydraulic support equipment, the second detection component is arranged at the bottom of the hydraulic support equipment, and the third detection component is arranged on one side of the hydraulic support equipment. The first detection component includes a first connecting piece and a first detection piece. The first connecting piece is arranged at the top of the mine roadway, and the first detection piece is arranged between the first connecting piece and the hydraulic support equipment. The first detection piece is used to detect the parallelism between the first connecting piece and the hydraulic support equipment. The second detection component includes a second connecting piece and a second detection piece. The second connecting piece is arranged at the bottom of the mine roadway, and the second detection piece is arranged between the second connecting piece and the hydraulic support equipment. The second detection piece is used to detect the perpendicularity between the second connecting piece and the hydraulic support equipment. The third detection component includes a third connecting piece and a third detection piece. The third connecting piece is located on the same side as the first connecting piece and the second connecting piece, and the third detection piece is arranged between the third connecting piece and the hydraulic support equipment. The third detection piece is used to detect the perpendicularity between the first connecting piece and the third connecting piece.

[0008] By adopting the above technical solution, when installing the hydraulic support equipment, the first connecting piece is parallel to the top of the hydraulic support equipment, and the first connecting piece is located between the top of the mine roadway and the hydraulic support equipment, so that the top of the hydraulic support equipment is arranged parallel in the mine roadway. Since the first detection piece can detect the parallelism between the first connecting piece and the hydraulic support equipment, when the hydraulic support equipment tilts under the gravity of the mine roadway, the hydraulic support equipment needs to be overhauled and the sinking data of the mine roadway can be calculated through the tilt degree. Similarly, the second detection piece can detect the perpendicularity between the second connecting piece and the hydraulic support equipment, so that it can be calculated whether the hydraulic support equipment on the second connecting piece has lateral displacement and angular tilt. The third detection piece can also detect the situation of tilt or displacement of the first connecting piece in the direction towards the third connecting piece. Through the three-point method, the force point analysis of the shape change of the support triangle formed by the hydraulic support equipment is carried out, so as to obtain the adjustment plan of the hydraulic support equipment, so as to timely detect the change of the support distance and quickly repair the hydraulic support equipment.

[0009] Optionally, the first connecting piece includes a top plate, a first abutting frame and a first reinforcing frame. The top plate is arranged at the top of the hydraulic support equipment, the first abutting frame is arranged at the end of the top plate away from the hydraulic support equipment, and the first reinforcing frame is arranged at the end of the first abutting frame away from the top plate. The first reinforcing frame is used to fill the gap between the first abutting frame and the mine roadway. The hydraulic support equipment includes a cross beam arranged at the top, and the cross beam abuts against the top plate and is parallel to each other.

[0010] 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.

[0011] Optionally, the first detection member includes a mounting box, a first detector, a receiving block and a first abutment. A clearance groove is provided at one end of the top plate close to the first detection member, the mounting box is arranged in the clearance groove, an opening is provided at the top of the mounting box, the first detector is arranged in the mounting box and close to the opening of the mounting box, a first elastic member is provided between the first detector and the mounting box, the first abutment is rotatably connected to the cross beam, and the end of the first abutment away from the cross beam can abut against the first detector.

[0012] By adopting the above technical solution, when the first detector is abutted by the first abutment member, the first detector sends a signal to notify the inspection personnel to inspect the hydraulic support equipment. In order to reduce the possibility of the first detector being crushed, the first detector can slide along 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. At this time, the first detector abuts against the first abutment member to generate an alarm, which promptly and effectively reminds the maintenance personnel to perform maintenance.

[0013] Optionally, the second connecting member includes a leveling plate and a base plate, the leveling plate is arranged on the ground, the base plate is arranged on the leveling plate, both the base plate and the leveling plate are provided with fixing parts, the fixing parts are used to fix the leveling plate and the base plate in the mine tunnel, a plurality of limiting protrusions are provided at one end of the base plate close to the leveling plate, the plurality of limiting protrusions face in the same direction, and a plurality of limiting grooves matching the limiting protrusions are provided on one side of the leveling plate close to the limiting protrusions.

[0014] By adopting the above technical solution, when installing the hydraulic support equipment, the leveling plate and the bottom plate are sequentially placed on the ground of the mine roadway, and both the leveling plate and the bottom plate are placed horizontally. Subsequently, fixing members are used to fix the leveling plate and the bottom plate. At the same time, the limiting protrusions are located in the limiting grooves, thereby increasing the tightness of the bottom plate on the leveling plate. Only when the force borne by the hydraulic support equipment exceeds the safe range, the limiting protrusions on the bottom plate will deform in the limiting grooves, causing the bottom plate to displace on the leveling plate and touch the second detection member, reminding the maintenance personnel that the hydraulic support equipment exceeds the safe support range and promptly performing maintenance on it.

[0015] Optionally, there are at least two second detection members. The at least two second detection members are respectively located at both ends of the bottom plate. The second detection member includes a mounting plate and a second detector. The mounting plate is slidably connected to the bottom plate. A receiving groove is formed below the bottom plate near the mounting plate. A second elastic member is provided in the receiving groove. The second elastic member is used to push the mounting plate towards the bottom plate. The second detection member is provided at one end of the mounting plate close to the bottom plate. The second detection member is used to detect the lateral displacement distance of the bottom plate.

[0016] By adopting the above technical solution, the second detection member detects both ends of the bottom plate. When the bottom plate touches the second detector, the second detector emits an alarm, reminding the maintenance personnel to perform maintenance. The second detector is slidably connected to the bottom plate, reducing the possibility of damaging the second detector when the second detector abuts against the bottom plate. And the second elastic member enables the second detector to keep abutting against the bottom plate and continuously generate an alarm until the maintenance personnel complete the maintenance of the hydraulic support equipment.

[0017] Optionally, the third connecting member includes a side plate, a second abutting frame, a second reinforcing frame and a fastener.

The fastener is used to fix the side plate, the second abutting frame and the second reinforcing frame on the side wall of the mine roadway.

[0018] By adopting the above technical solution, the side plate, the second abutting frame and the second reinforcing frame are sequentially placed at the ends of the roof and the leveling plate from left to right. The second reinforcing frame is also made of a flexible material, improving the friction between the second abutting frame and the side wall of the mine roadway and facilitating the adjustment of the second abutting frame, the roof and the leveling plate to a vertical state.

[0019] Optionally, the third detector includes a mounting post, a mounting block, a third detector, and a positioning member. The mounting post is inclined between the top plate and the side plate.

[0020] By adopting the above technical solution, the mounting post is inclined and installed under the top plate to monitor the angle between the top plate and the side plate. When the positioning member fixes the mounting block, the third detector is horizontally located under the top plate. When the top plate tilts, it abuts against the third detector, and the third detector emits a signal to remind the maintenance personnel to perform maintenance.

[0021] Optionally, a sliding groove is formed at one end of the side plate close to the mounting block. The positioning member is located in the sliding groove. The positioning member is located at the bottom of the mounting block. The positioning member includes a support rod and a third elastic member. One end of the support rod abuts against the mounting block, and the other end abuts against the side plate. The support rod is an elastic support rod. The third elastic member is disposed in the sliding groove, and both ends of the third elastic member abut against the side plate of the mounting block respectively.

[0022] By adopting the above technical solution, when the third detector is under pressure, the mounting post and the mounting block move downward together. The third elastic member and the support rod support the mounting block. When the mounting block moves downward, the third elastic member and the support rod are squeezed, reducing the possibility of damage to the third detector.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:
