[0016] The mine track type mobile support detection device has the following beneficial effects:

[0017] 1. This mine tracked mobile support and detection device uses the rotation of a cam to drive the docking housing and piercing pins to reciprocate, allowing several piercing pins to pierce and break up the compacted soil on the track. The ends of the piercing pins are tapered, making it easier for them to penetrate the compacted soil and break it up.

[0018] 2. This mine tracked mobile support and detection device utilizes the horizontal plate to ensure the state of the piercing pins. The interaction between the connecting shaft and the adjusting groove allows the piercing pins to initially move vertically, achieving a vertical piercing effect on compacted soil. Subsequently, the adjusting groove drives the connecting shaft to move the horizontal plate horizontally, which in turn causes several piercing pins to swing. This swinging motion of the piercing pins causes them to swing laterally, creating horizontal grooves in the compacted soil and further improving the breaking effect.

[0019] 3. This mine tracked mobile support and detection device utilizes the expansion plates on the puncture pin. When the puncture pin swings, the adjusting shaft slides in the drive groove, driving the adjusting shaft and the docking column to move downwards. This causes the expansion plates on both sides of the puncture pin to expand outwards. The expansion of the expansion plates supports the compacted soil, increases the size of the groove during lateral swing, and makes it easier for the compacted soil on the track to break and detach.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] This invention has developed a tracked mobile support detection device for mining, which has the following characteristics:

[0034] 1. This device is used for support in tunneling and fully mechanized mining faces to prevent roof collapse and roadway disintegration, protecting the personal safety of workers during support operations. The walking mechanism consists of tracked wheels 5, allowing for tracked movement. The uprights 2 have internal hydraulic rods 24, or oil cylinders, which can extend and retract vertically. Protective frames 25 are provided on the left, right, and front of the support frame 4 to protect operators. The power system can use power modules, a fully mechanized mining face emulsion pump station, or a pneumatic motor, and can also be used in conjunction with a tunneling machine. The operating system can use a remote controller and manual operation. Remote operation can also connect to a ground control station via network signal, enabling intelligent unmanned operation. All of the above are existing technologies; those skilled in the art can select according to actual needs. A mobile monorail can also be installed on the support frame 4 to assist in equipment maintenance and cargo lifting (not shown in the figure). This is existing technology; those skilled in the art can select and install it according to actual needs. The use of this device can prevent various roof falls, disintegrations, and harmful gas accidents in coal mine tunneling roadways.

[0035] 2. A pressure sensor 23 is installed to detect the pressure at the top of the working face in the coal mine tunnel. When the pressure at the top exceeds the set value, the monitoring system will automatically issue an early warning to remind workers to take personal protective measures and reinforce the tunnel. When the pressure exceeds the limit value, the support of each working part will automatically shut down and lock to prevent the tunnel from collapsing, and at the same time remind workers to evacuate.

[0036] 3. Provide real-time early warning of roadway sidewall pressure and collapse. When the sidewall pressure is too high and there is a risk of collapse, issue an early warning signal in a timely manner to remind front-line workers to take preventive measures in advance.

[0037] 4. Each pressure-bearing system is equipped with a pressure display system, which can check the pressure changes in various parts of the roadway at any time.

[0038] 5. Equipped with humidity and various harmful gas detection systems, the system analyzes humidity conditions through overall technology. When the humidity exceeds the previous average, the system will remind you to pay attention to the hydrological situation. When various harmful gases exceed the standard, the system will also issue an early warning.

[0039] 6. This mobile detection platform can transmit the detected data to the ground control room in real time for data collection and analysis. The sensing devices, display devices, early warning devices, power systems and operating systems mentioned above are all existing technologies. The specific operation procedures will not be elaborated here.

[0040] Based on this, the inventors further propose the following technical solutions.

[0041] Example 1, please refer to Figures 1 to 11 A mine tracked mobile support detection device includes a walking unit, on which columns 2 are provided on both sides of the top. A support frame 3 is slidably arranged inside the column 2. A support frame 4 is installed on the top of the support frame 3. The walking unit includes a support housing 1 fixedly connected to the column 2 and track wheels 5 installed inside the support housing 1. It also includes a pressure sensor 23, which is installed on the top of the support frame 4 for detecting the support force. A connecting sleeve 6 is fixedly installed on the inner wall of the supporting housing 1. A lifting rod 7 is slidably arranged inside the connecting sleeve 6. A connecting spring 8 is provided between the connecting sleeve 6 and the lifting rod 7 to enable it to return to its original position. A docking housing 9 is fixed to the end of the lifting rod 7. A swing groove 16 is formed on the inner surface of the docking housing 9, and a piercing pin 15 for removing soil clumps from the track wheel 5 is installed in the swing groove 16; a cam 10 is fitted to the outer surface of the docking housing 9, and a drive motor 11 is installed on the outer wall of the cam 10; a hydraulic rod 24 is fixedly installed inside the column 2, and the end of the hydraulic rod 24 is fixedly connected to the support frame 3; a protective frame 25 is installed on the outer side of the support frame 4. First, by controlling the movement of the hydraulic rod 24 installed inside the column 2, the hydraulic rod 24 is fixedly connected to the support frame 3. When the hydraulic rod 24 moves inside the column 2, it will simultaneously drive the support frame 3 to move upward. Each column 2 is equipped with a hydraulic rod 24, which can synchronously drive the support frame 3 to move upward. The upward movement of the support frame 3 drives the support frame 4 to move upward synchronously, supporting the roof of the mine working face. The pressure sensor 23 can detect the roof pressure value. By setting the trigger value of the pressure sensor, when various roof falls or collapses occur in the mine, the pressure sensor can detect them in time and trigger an automatic warning to remind the staff to take personal protective measures and reinforce the roadway. Furthermore, humidity and various harmful gas detection devices can be installed on the column 2 to monitor the humidity and various harmful gases in the mine tunnel, thereby improving the safety of operators. A protective frame 25 is also rotatably installed on the support frame 4. When the roof support is not needed, the height can be adjusted appropriately, and the protective frame 25 can be rotated and rotated to a vertical position. Then, the workers can lock multiple sets of protective frames 25 with wires, etc., and place a support mesh plate on the support frame 4 so that the operators can stand on the mesh plate laid on the support frame 4 and use this device as a lifting platform. When the device needs to move, the track wheel 5 is driven to rotate, which drives the device to move forward or backward. The track wheel 5 is existing technology, and those skilled in the art can select it according to actual needs. It will not be described in detail here. When the track wheel 5 moves in the mine and the hardened soil on the track needs to be cleaned, the drive motor 11 inside the support housing 1 is controlled to rotate. The drive motor 11 is fixedly connected to the cam 10, which drives the cam 10 to rotate inside the support housing 1. The cam 10 is in close contact with the docking housing 9. When the cam 10 rotates, it causes the docking housing 9 to move downward. The docking housing 9 is provided with several piercing pins 15, which causes the docking housing 9 to drive the several piercing pins 15 to approach the track. The front end of the piercing pin 15 is tapered. This design makes it easier for the piercing pin 15 to penetrate the hardened soil on the track, and to break up the hardened soil. This makes it easier for the hardened soil on the track to disperse and detach, thus cleaning the hardened soil on the track. The outer wall of the docking housing 9 is also equipped with a lifting rod 7. When the cam 10 rotates, it will exert a downward pressure on the docking housing 9, causing the docking housing 9 to drive the lifting rod 7 to slide inside the connecting sleeve 6. A connecting spring 8 is provided between the connecting sleeve 6 and the lifting rod 7. When the lifting rod 7 moves downward, it will compress the connecting spring 8 at the same time. Then, the subsequent return spring force of the connecting spring 8 will drive the docking housing 9 and the piercing pin 15 to reset. Through the cooperation of the cam 10 and the connecting spring 8, the docking housing 9 and the piercing pin 15 can move up and down reciprocally, so as to achieve the effect of piercing, breaking and cleaning the soil hardened on the track.

[0042] Example 2 is an improvement on Example 1. The track has protrusions and grooves. When the puncture pin 15 contacts a protrusion, the same puncture distance can cause the puncture pin 15 to collide with the track protrusion, leading to bending and damage. For details, please refer to [link to relevant documentation]. Figures 1 to 11 The cam 10 includes a hard wheel 101, an elastic bladder 102, and a wear-resistant layer 103. The elastic bladder 102 is provided on the outer side of the hard wheel 101, and the wear-resistant layer 103 is wrapped around the outer side of the elastic bladder 102. The wear-resistant layer 103 is made of rubber, and the wear-resistant layer 103 is bonded to the hard wheel 101. When the docking housing 9 drives the puncture pin 15 to move downward, after the puncture pin 15 contacts the hard protrusion on the track, the cam 10 still tends to drive the docking housing 9 and the puncture pin 15 to move downward. At this time, due to the influence of the hard protrusion on the track, the puncture pin 15 is difficult to continue to move downward. As the cam 10 continues to rotate, the elastic bladder 102 and wear-resistant layer 103 sleeved on the outside of the hard wheel 101 will undergo a certain deformation. By utilizing the deformation of the elastic bladder 102 and wear-resistant layer 103, the docking housing 9 and the puncture pin 15 can still ensure the normal rotation of the cam 10 when they stop moving downward. Through this setting, the puncture pin 15 is protected and the bending and damage of the puncture pin 15 are avoided. Furthermore, the wear-resistant layer 103 provided on the outside of the elastic bladder 102 protects the elastic bladder 102, improves the wear resistance of the cam 10, and avoids damage to the elastic bladder 102 due to prolonged use. The elastic bladder 102 is hollow, and a medium can be injected into the elastic bladder 102 to change the expansion hardness of the elastic bladder 102. The medium can be air, and the hardness of the elastic bladder 102 can be changed by adjusting the amount of air injected into the elastic bladder 102. This, in turn, adjusts the amount of compressive force that triggers the deformation of the elastic bladder 102 and the wear-resistant layer 103 to achieve buffer protection for the puncture needle 15. This allows operators to select an appropriate buffering force to protect the puncture needle 15 according to actual needs and the hardness of the compacted soil.

[0043] Example 3 is an improvement on Example 1. When using only the piercing pin 15 to break up the soil, the spacing between the piercing pins 15 can easily cause some compacted soil to remain intact after piercing, making it difficult to break up and detach. For details, please refer to [link to example]. Figures 1 to 11 A horizontal plate 12 is movably installed inside the docking housing 9. The horizontal plate 12 is sleeved on the outside of the puncture needle 15 to restrict the state of the puncture needle 15. A docking shaft 13 is fixedly installed on the outer wall of the horizontal plate 12. An adjustment groove 14 is opened inside the docking housing 9 to restrict the movement of the docking shaft 13. The adjustment groove 14 includes a vertical groove 141 and an inclined groove 142 connected in sequence. As the cam 10 drives the docking housing 9 downward, the docking housing 9 simultaneously drives the docking shaft 13, which is slidably disposed inside, downward. The docking shaft 13 is slidably disposed inside the adjusting groove 14. As the docking housing 9 drives the docking shaft 13 downward, the docking shaft 13 will first slide inside the vertical groove 141. A horizontal plate 12 is fixed to the end of the docking shaft 13, and the horizontal plate 12 is sleeved on the outside of the piercing pin 15. The horizontal plate 12 and the docking shaft 13 are used to ensure the stability of the piercing pin 15 during piercing, so that the piercing pin 15 can pierce the compacted soil vertically downward. As the docking housing 9 drives the piercing pin 15 to continue moving, the piercing pin 15 will penetrate into the compacted soil while the docking shaft 13 continues to slide inside the vertical groove 141. When the piercing pin 15 is about to contact the track, as the docking housing 9 continues to move, the docking shaft 13 will slide from the vertical groove 141 into the inclined groove 142, and the docking shaft 13 will exert a lateral pull on the horizontal plate 12, causing the horizontal plate 12 to slide inside the docking housing 9. As the horizontal plate 12 slides laterally inside the docking housing 9, and the piercing pin 15 is rotated and set inside the swing groove 16, as the horizontal plate 12 moves laterally, several piercing pins 15 will swing slightly. Through this setting, the piercing pin 15 vertically penetrates the compacted soil and then swings laterally, creating a horizontal groove on the compacted soil, further achieving the effect of breaking up the compacted soil on the track, effectively avoiding the situation where the compacted soil remains intact and difficult to remove after piercing.

[0044] Example 4 is an improvement upon Example 3, further enhancing the breaking effect on compacted soil. For details, please refer to [link / reference]. Figures 1 to 11An adjusting shaft 17 is movably installed inside the puncture needle 15. A drive groove 18 for driving the adjusting shaft 17 is opened inside the docking housing 9. A docking post 19 is fixed at the end of the adjusting shaft 17. The docking post 19 is slidably disposed inside the puncture needle 15. A movable head 21 is movably connected to the end of the docking post 19. A movable ball 22 is fixedly disposed at the end of the movable head 21. An expansion plate 20 is slidably disposed on the inner side of the puncture needle 15. The expansion plate 20 and the movable ball 22 are rotatably connected. There are two expansion plates 20 symmetrically arranged about the docking column 19. The expansion plates 20 are used to support the clump of soil. The drive groove 18 is an arc-shaped groove. The center of the drive groove 18 is not concentric with the rotation center of the piercing pin 15. When the puncture needle 15 rotates on the swing groove 16, the drive groove 18 opened inside the docking housing 9 is used, and the adjusting shaft 17 is slidably set inside the drive groove 18. When the puncture needle 15 swings, it will synchronously drive the adjusting shaft 17 to slide inside the drive groove 18. Because the center of the drive groove 18 is not concentric with the rotation center of the puncture needle 15, as the puncture needle 15 rotates and the drive groove 18 restricts it, the adjusting shaft 17 will slide down slightly inside the puncture needle 15. When the adjusting shaft 17 slides down, it will synchronously drive the docking post 19 to slide down. When the docking post 19 slides down, it will drive the movable head 21 set at the end to move synchronously. A movable ball 22 is fixed to the end of the movable head 21, and the movable ball 22 is rotatably connected to the expansion plate 20. Through the setting of the drive groove 18 and the movable head 21, the expansion plate 20 slides inside the piercing pin 15, so that the expansion plates 20 on both sides expand on the piercing pin 15. In the process of the piercing pin 15 swinging laterally to open the transverse groove of the compacted soil, the expansion movement of the expansion plate 20 is used to generate an outward compressive force on the compacted soil, thereby making the distance between the soil on both sides of the transverse groove greater, further improving the crushing effect of the compacted soil, making it easier for the compacted soil to be removed from the track, and improving the cleaning effect of the compacted soil on the track. It should be noted that the expansion movement of the expansion plate 20 is during the swinging process of the piercing pin 15. Therefore, when the piercing pin 15 is vertically inserted into the soil, the expansion plate 20 will not expand, so as to avoid the expansion plate 20 not being able to fully contact the compacted soil and affecting the expansion and crushing effect of the compacted soil.

[0046] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
