[0010] The stand posture warning system receives data from the pressure monitoring system and the posture monitoring system, and compares and analyzes these actual data with the standard parameters in the model constructed by the stand posture model building system;

[0011] The posture adjustment system determines the part that needs to be adjusted and the direction of adjustment according to the warning information, and adjusts the bracket through the posture adjustment system;

[0012] The top beam, shielding beam, connecting rod and base of the bracket are all provided with inclination sensors. A protective shell is fixedly installed on the outside of the bracket, and a buffer spring is fixedly installed on the inner wall of the protective shell. The buffer spring is rotatably installed on the outside of the inclination sensor. The inclination sensor is arranged inside the protective shell. The buffer spring can effectively slow down and weaken the vibration of the protective shell.

[0013] Furthermore, a pressure rod is rotatably installed on the outside of the inclination sensor, and a disk is fixedly installed on the outside of the pressure rod. A circular through hole is opened on the disk, and the disk is slidably installed on the inner wall of the sealing cylinder. The sealing cylinder is rotatably installed on the outside of the protective shell. When the circular through hole moves, the air in the sealing cylinder will pass through the circular through hole to generate a damping force, and the generation of the damping force will slow down the movement of the pressure rod.

[0014] Furthermore, there are four buffer springs, which are evenly distributed at the upper left corner, lower left corner, upper right corner and lower right corner of the inclination sensor, so that vibrations generated in different directions to the protective shell can be mitigated and weakened by the buffer springs.

[0015] Furthermore, a temperature sensor is fixedly installed on the outside of the protective shell, and the temperature sensor is electrically connected to the inclination sensor through connecting wires. Temperature data is monitored by the temperature sensor, and the data is transmitted to the inclination sensor through the connecting wires, and the temperature and inclination data are transmitted to the terminal together.

[0016] Furthermore, the protective shell is also provided with a heat dissipation mechanism, which includes a heat dissipation port, and the heat dissipation port is opened on the right side of the protective shell to improve the working efficiency of the tilt sensor and avoid overheating.

[0017] Furthermore, an inner concave fixing plate is fixedly installed on the outside of the sealing cylinder, a sliding iron ring is slidably installed on the inner concave fixing plate, a pull rod is hinged on the outside of the sliding iron ring, and the outside of the pull rod is hinged to the transverse sliding plate.

[0018] Furthermore, a transverse slide groove is provided on the inner wall of the protective shell above the heat dissipation port, and the transverse slide plate is slidably installed in the transverse slide groove. A cleaning brush is fixedly installed on the outside of the transverse slide plate. The cleaning brush is arranged near the entrance and exit of the heat dissipation port, and the movement of the cleaning brush will clean and scrape away impurities accumulated at the heat dissipation port.

[0019] Furthermore, the transverse skateboard is also provided with an auxiliary mechanism, which includes a semicircular protrusion, and the semicircular protrusion is fixedly installed on the outside of the transverse skateboard.

[0020] Furthermore, a rubber push rod is fixedly installed on the outside of the pull rod, and the outermost end of the rubber push rod is arranged close to the outside of the semicircular protrusion.

[0021] Furthermore, the outermost end of the rubber push rod is set to be spherical, and the cleaning brush can achieve a self-cleaning effect, thereby improving the overall heat dissipation efficiency.

[0022] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0023] 1. The present invention is provided with a buffer spring and a disc, and four buffer springs in different directions, so that the vibrations generated in different directions of the protective shell can be slowed down and weakened by the buffer springs. When the circular through hole moves, the air in the sealing cylinder passes through the circular through hole to generate a damping force. The damping force slows down the movement of the pressure rod, and further slows down the displacement of the inclination sensor, achieving a secondary buffering effect. The buffering effect is improved by two bufferings, which improves the overall applicability and effectively protects the safety and stability of the inclination sensor during the working process of the bracket.

[0024] 2. The present invention is provided with a heat dissipation mechanism, and the movement of the sliding iron ring will drive the end of the pull rod close to the sliding iron ring to move, so that the other end of the pull rod will pull the horizontal slide plate to move, so that the horizontal slide plate will move along the horizontal slide groove, and the movement of the horizontal slide plate will drive the cleaning brush to move, and the following movement of the cleaning brush will clean and scrape the impurities accumulated at the heat dissipation port, thereby improving the ventilation flow rate of the heat dissipation port, while avoiding the long-term adhesion of dust and preventing blockage, thereby improving the heat dissipation efficiency;

[0025] 3. The present invention is provided with an auxiliary mechanism. When the rubber push rod rotates upward, the spherical end of the rubber push rod will be squeezed with the semicircular protrusion. First, the rubber push rod will hit the semicircular protrusion to generate vibration. Then, the rubber push rod will slide, rub and squeeze on the semicircular protrusion, thereby generating multiple friction and squeezing vibrations. The vibration will be transmitted to the nearby cleaning brush, causing the cleaning brush to vibrate, thereby causing impurities attached to the cleaning brush to fall off.

[0026] 4. The present invention arranges an auxiliary mechanism on the cleaning brush to prevent impurities from accumulating on the cleaning brush when the cleaning brush is moving for cleaning, thereby preventing the cleaning efficiency from being affected. If too much impurities accumulate, the impurities on the cleaning brush may easily attach to the heat dissipation port for a second time, affecting the heat dissipation efficiency. The cleaning brush can achieve a self-cleaning effect, thereby improving the overall heat dissipation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0038] like Figures 1 to 8 As shown, the present invention includes a bracket 1, and further includes:

[0039] The support posture model building system constructs an initial support posture model based on the design parameters, mechanical principles and ideal working state information of the support 1;

[0040] The pressure monitoring system measures the pressure inside the oil cylinder by installing a pressure sensor. The pressure sensor is installed in the inner cavity of the oil cylinder, usually on the top or side of the oil cylinder. The pressure sensor converts the measured pressure signal into an electrical signal and transmits it to the controller or data acquisition device of the monitoring system through cables or wireless communication.

[0041] The posture monitoring system uses the inclination sensor 3 to collect the real-time posture data of the bracket 1 and monitor the posture changes of the whole process when the bracket 1 moves;

[0042] The posture warning system receives data from the pressure monitoring system and the posture monitoring system, and compares and analyzes these actual data with the standard parameters in the model constructed by the support 1 posture model building system;

[0043] The posture adjustment system determines the part that needs to be adjusted and the direction of adjustment according to the warning information, and adjusts the support 1 through the posture adjustment system. According to the posture warning information, the staff derives the control strategy, controls the posture control jack on the support 1, and uses the electro-hydraulic controller to adjust the flow direction and pressure of the hydraulic oil to control the extension or retraction of the jack, thereby realizing the adjustment of the posture of the hydraulic support;

[0044] The bracket 1 includes structures such as a top beam 101, a shielding beam 102, a connecting rod 103 and a base 104, and the top beam 101, the shielding beam 102, the connecting rod 103 and the base 104 of the bracket 1 are all provided with an inclination sensor 3. A protective shell 2 is fixedly installed on the outside of the bracket 1, and a buffer spring 4 is fixedly installed on the inner wall of the protective shell 2. The buffer spring 4 is externally rotatably installed on the outside of the inclination sensor 3. There are four buffer springs 4, which are evenly distributed at the upper left corner, lower left corner, upper right corner and lower right corner of the inclination sensor 3. The inclination sensor 3 is arranged inside the protective shell 2, and a pressure rod 5 is rotatably installed on the outside of the inclination sensor 3. A disk 6 is fixedly installed on the outside of the pressure rod 5, and a circular through hole 7 is opened on the disk 6. The disk 6 is slidably installed on the inner wall of a sealing cylinder 8, and the sealing cylinder 8 is externally rotatably installed on the inner wall of the protective shell 2. A temperature sensor 9 is fixedly installed on the outside of the protective shell 2, and the temperature sensor 9 is electrically connected to the inclination sensor 3 through a connecting wire 10.

[0045] In the above technical solution, first, the support posture model establishment system is run, and based on the design parameters, mechanical principles and ideal working state information of the support 1, an initial support posture model is constructed, which includes the position relationship, angle relationship and corresponding pressure range and other parameters of each component (such as top beam, side guard plate, push rod, etc.) of the support when it is working normally. Then the pressure monitoring system and the posture monitoring system are started almost at the same time, and the pressure sensor and the inclination sensor 3 are used to monitor the data. The inclination sensor 3 is arranged inside the protective shell 2, so that the protective shell 2 can protect the inclination sensor 3. When the support 1 is working in the coal mine, During operation, the vibration generated by the operation will drive the protective housing 2 to vibrate together. However, since a buffer spring 4 is provided between the inclination sensor 3 and the protective housing 2, the buffer spring 4 can effectively slow down and weaken the vibration of the protective housing 2. At the same time, since four buffer springs 4 are provided in different directions, the vibrations generated in different directions on the protective housing 2 can be slowed down and weakened by the buffer spring 4, so as to achieve all-round effective buffering, thereby reducing the vibration damage of the inclination sensor 3. At the same time, the buffer spring 4 cannot isolate the vibration, so the inclination sensor 3 will still move under the buffering of the buffer spring 4. When the inclination sensor 3 When the inclination sensor 3 is displaced, the inclination sensor 3 will pull the pressure rod 5 to move, and the pressure rod 5 will drive the disc 6 to follow the movement, and the disc 6 will slide on the inner wall of the sealing cylinder 8. Since the movement of the disc 6 will drive the circular through hole 7 to follow the movement, the circular through hole 7 will allow the air in the sealing cylinder 8 to pass through the circular through hole 7 when it moves, thereby generating a damping force. The generation of the damping force will slow down the movement of the pressure rod 5, and further slow down the displacement of the inclination sensor 3, achieving a secondary buffering effect. Moreover, since the sealing cylinder 8 is rotatable, the damping force generated by the pressure rod 5, the disc 6 and the circular through hole 7 can be applied to The inclination sensor 3 is adapted to be displaced in different directions to improve the overall applicability. The inclination sensor 3 monitors the inclination data, and the temperature sensor 9 monitors the temperature data. By connecting the wire 10, the temperature sensor 9 transmits the temperature data to the inclination sensor 3, and the inclination sensor 3 transmits the temperature and inclination data to the terminal together. Finally, by providing the buffer spring 4 and the disc 6, the buffer effect is improved by buffering twice, and the buffer springs 4 in four directions and the rotatable sealing cylinder 8 are used to achieve all-round buffering, thereby improving the overall applicability and effectively protecting the safety and stability of the inclination sensor 3 during the working process of the bracket 1.

[0046] like Figure 8 As shown in the figure, after receiving the data from the pressure monitoring system and the posture monitoring system, it will enter the posture warning system, which includes:

[0047] By setting up pressure sensors and monitoring data including side guard pressure analysis, top plate pressure analysis and push rod 105 pressure analysis;

[0048] The first section, side guard pressure analysis and side guard travel analysis:

[0049] Side guard pressure analysis: in the control system, set the normal range of side guard pressure;

[0050] When the collected side guard pressure data is greater than the set normal pressure upper limit, it is determined that the pressure is too high, triggering the rack squeeze warning. The warning signal is displayed through the underground sound and light alarm and monitoring system to remind the staff to pay attention to the possible rack squeeze between the supports. By installing a pressure sensor near the hydraulic cavity inside the side guard plate of the support, the pressure sensor converts the measured pressure signal into an electrical signal, and the converted electrical signal is transmitted to the data acquisition device through a shielded cable;

[0051] Side guard travel analysis: Similarly, set the normal range of side guard travel;

[0052] When the monitored side guard stroke data exceeds this normal range, it is determined to be abnormal and the center distance warning is triggered. This warning information will inform the staff that the center distance between the brackets may be abnormal and needs to be checked and adjusted. The displacement sensor is installed on the side guard plate to ensure that it can directly measure the stroke of the side guard plate. The displacement sensor converts the physical displacement of the side guard stroke into an electrical signal, which is transmitted to the data acquisition equipment via a cable to perform data monitoring range analysis.

[0053] Section 2, roof pressure analysis:

[0054] The top plate pressure threshold is set. According to the design parameters and working requirements of the hydraulic support, the two key top plate pressure thresholds, the initial support pressure and the upper limit of the fluid replenishment, are set. The setting of the initial support pressure is based on the initial support requirements of the hydraulic support for the top plate. The relationship between the initial support pressure Ptop (top plate initial support pressure) and the cylinder internal pressure Pcylinder (cylinder initial support internal pressure) can be calculated through the structural parameters of the support:

[0055] If the hydraulic support has n columns and the piston area of ​​each column is A, then

[0056] P top initial = n × A × P cylinder initial;

[0057] For the upper limit of liquid replenishment, there is also a similar relationship. Let the upper limit pressure of the top plate liquid replenishment be Ptop replenishment, and the upper limit internal pressure of the oil cylinder liquid replenishment be Pcylinder replenishment, then Ptop replenishment = n×A×Pcylinder replenishment;

[0058] Roof pressure judgment and warning: when the collected roof pressure data is less than the initial support pressure, an underpressure warning is triggered; if the roof pressure is greater than the upper limit of the fluid replenishment, an overpressure warning is triggered;

[0059] Compare the standard frame state with the frame states on both sides. After the underpressure warning is triggered, compare the posture data of the current support with the standard frame state data. If the posture meets the normal standard but the pressure is underpressure, this may mean that there is an empty top or insufficient top connection, triggering an empty top or insufficient top connection warning;

[0060] After the overpressure warning is triggered, if the posture is still in compliance, there may be a risk of top break or top leakage, triggering a top break or top leakage warning;

[0061] Calculate the difference in mining height between adjacent supports. When the difference in mining height is too large, trigger the frame bite warning. Install displacement sensors on the supports to obtain the mining height data of each support. Then subtract the mining height of one support from the mining height of the adjacent support to get the mining height difference. Set a threshold for the mining height difference in the control system. When the calculated mining height difference exceeds this threshold, the system will trigger the frame bite warning.

[0062] When the tilt sensor 3 detects an abnormal roll angle, a rollover warning is triggered.

[0063] Section 3: Pushrod 105 Pressure Analysis:

[0064] Push rod pressure threshold setting: set the push rod protection pressure threshold according to the push rod design and working requirements;

[0065] Push rod pressure judgment and warning: when the collected push rod pressure data is greater than the protection pressure, an overpressure warning is triggered.

[0066] When the warning signal is issued, the type of warning, occurrence time, bracket number involved and other information are recorded in the monitoring system. After receiving the warning, the staff can confirm the warning situation through the monitoring system and turn off the sound and light alarm to indicate that they are aware of the warning content. According to the type of warning, the staff will take corresponding adjustment measures.

[0067] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in the present invention, a heat dissipation mechanism is also provided, which includes a heat dissipation port 11, and the heat dissipation port 11 is opened on the right side of the protective shell 2. An inner concave fixing plate 12 is fixedly installed on the outside of the sealing cylinder 8, and a sliding iron ring 13 is slidably installed on the inner concave fixing plate 12. The material used for the disk 6 is a magnetic material of a magnet, so that the movement of the disk 6 can be synchronously displaced with the sliding iron ring 13. A pull rod 14 is hinged on the outside of the sliding iron ring 13, and the pull rod 14 is hinged on the outside of the transverse slide 15. A transverse slide groove 16 is opened on the inner side wall of the protective shell 2 above the heat dissipation port 11, and the transverse slide groove 16 is slidably installed in the transverse slide groove 16, and a cleaning brush 17 is fixedly installed on the outside of the transverse slide 15, so that the transverse slide 15 can drive the cleaning brush 17 to work together when moving, and the cleaning brush 17 is arranged near the entrance and exit of the heat dissipation port 11.

[0068] In the above technical scheme, when the bracket 1 is working and vibrates, the inclination sensor 3 pulls the pressure rod 5 to move, and the pressure rod 5 drives the disc 6 to follow the movement. The disc 6 will pull the sliding iron ring 13 on the concave fixed plate 12 to follow the movement through the magnetic attraction, and the sliding iron ring 13 will slide on the concave fixed plate 12. The movement of the sliding iron ring 13 will drive the end of the pull rod 14 close to the sliding iron ring 13 to follow the movement, so that the other end of the pull rod 14 will pull the transverse slide plate 15 to move, so that the transverse slide plate 15 will move along the transverse slide groove 16, and the movement of the transverse slide plate 15 will drive the cleaning brush 17 to follow the movement, and the following movement of the cleaning brush 17 will clean and scrape the impurities accumulated at the heat dissipation port 11, thereby improving the ventilation flow rate of the heat dissipation port 11, while avoiding the long-term adhesion of dust and preventing blockage, thereby improving the heat dissipation efficiency.

[0069] like Figure 6 and Figure 7 As shown, in the present invention, an auxiliary mechanism is also provided on the transverse skateboard 15, and the auxiliary mechanism includes a semicircular protrusion 19, and the semicircular protrusion 19 is fixedly installed on the outside of the transverse skateboard 15. A rubber push rod 18 is fixedly installed on the outside of the pull rod 14. The outermost end of the rubber push rod 18 is set to be spherical to facilitate friction and extrusion. The outermost end of the rubber push rod 18 is set close to the outside of the semicircular protrusion 19.

[0070] In the above technical solution, since the displacement of the sealing cylinder 8 is omnidirectional, when the displacement of the sealing cylinder 8 includes movement in the up and down directions, the sealing cylinder 8 will drive the concave fixed plate 12 to move along, and the concave fixed plate 12 will drive the sliding iron ring 13 to move along and along, and the sliding iron ring 13 will drive the pull rod 14 to rotate upward or downward, so that the pull rod 14 will drive the rubber push rod 18 to rotate upward or downward, and when the rubber push rod 18 rotates upward, the rubber push rod 18 will cause its own spherical end to be squeezed with the semicircular protrusion 19, and first the rubber push rod 18 will collide with the semicircular protrusion 19, and then the rubber push rod 18 will slide, rub and squeeze on the semicircular protrusion 19, thereby generating multiple friction and squeezing vibrations, and the vibrations will be transmitted to the nearby cleaning brush 17, causing the cleaning brush 17 to vibrate, thereby allowing impurities attached to the cleaning brush 17 to fall off, avoiding the accumulation of impurities on the cleaning brush 17 when the cleaning brush 17 is moving for cleaning, affecting the cleaning efficiency, and if the impurities accumulate too much, it is easy to cause the impurities on the cleaning brush 17 to attach to the heat dissipation port 11 for the second time, affecting the heat dissipation efficiency. Finally, the cleaning brush 17 can achieve a self-cleaning effect, thereby improving the overall heat dissipation efficiency.

[0071] To sum up, by providing the buffer spring 4 and the disc 6, the buffer effect is improved through double buffering, and the buffer springs 4 in four directions and the rotatable sealing cylinder 8 are used to achieve all-round buffering, thereby improving the overall applicability, effectively protecting the safety and stability of the inclination sensor 3 during the operation of the bracket 1, and at the same time improving the heat dissipation efficiency through the heat dissipation mechanism and the auxiliary mechanism, thereby improving the overall working efficiency in the coal mine.

[0072] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
