Description

Technical Field

[0001] This invention belongs to the field of hydraulic equipment technology, specifically a hydraulic support for paste filling template and a leakage monitoring method. Background Technology

[0002] As one of the green mining technologies in coal mines, paste filling mining technology aims to solve the problems of coal pressure from "three downs and one up" (referring to coal mining, mining, and mining operations), achieve zero discharge of surface gangue, protect the mining environment, and improve the coal mining resource recovery rate. The low efficiency of isolation and sealing of goaf areas is an important factor restricting the efficient production of paste filling working faces. Therefore, various paste filling templates and hydraulic supports have appeared on the market.

[0003] For example, the invention with patent application number 202410587017.5 relates to the field of mine filling operation construction device, specifically disclosing a high-efficiency paste filling template hydraulic support, including: a front section of the hydraulic support and a rear section of the hydraulic support. The rear section of the hydraulic support includes a rear top beam and a rear base. The rear top beam and the rear base are detachably connected to the front section of the hydraulic support, respectively. A rear column is provided between the rear top beam and the rear base. The upper and lower ends of the rear column are detachably connected to the rear top beam and the rear base, respectively. A filling space is provided on the inner side of the rear top beam. A baffle with the same cross-sectional shape as the rear top beam is provided on the edge of the rear top beam. The baffle isolates the filling space on the inner side of the rear top beam.

[0004] However, existing hydraulic supports for paste filling templates encounter various problems during application. For example, the aforementioned high-efficiency hydraulic supports for paste filling templates require the control of multiple hydraulic devices to enable the hydraulic supports to perform various actions. This necessitates the use of multiple hoses to deliver hydraulic oil and control the hydraulic devices. Although multiple hoses can be integrated and controlled via a hydraulic integration module, it is still difficult and time-consuming for operators to inspect the connections of each hose individually to detect leaks. Summary of the Invention

[0005] To address the difficulty in detecting leaks at hose connections, this invention provides a hydraulic support for a paste filling template and a leak monitoring method.

[0006] The present invention adopts the following technical solution: a hydraulic support for a paste filling template, comprising a hydraulic support for a paste filling template and a hydraulic integrated module installed on the hydraulic support for the paste filling template, wherein the hydraulic integrated module comprises an oil circuit board and heat dissipation fins and multiple water outlet components installed on the oil circuit board; Each water outlet connection is equipped with a leak monitoring unit, which is connected to the airflow circulation system. The leakage monitoring unit includes: Support frame two is located at the bottom of the water outlet component; The sponge block is installed inside the second support frame; A thin-film humidity sensor embedded in a sponge block; The airflow circulation system includes: Air guide component five connects to all leak monitoring units; Air guide component six is ​​rotatably installed inside air guide component five, and air guide groove three is opened on its outer wall; Cooling element, embedded in the inner wall of the gas guide component; A forward and reverse motor drives the six-sided air guide component to rotate; The waste gas recovery assembly includes: Multiple air guide components seven are fixedly installed on the bottom outer side of air guide component five; The distribution box is located between adjacent air guides and has an exhaust port on the side facing the heat dissipation fins. Air guide component eight connects air guide component seven to a one-way valve; Among them, one of the three air guide channels can be connected: First location: the gas guide channel connecting the leak monitoring unit; Second position: The heat dissipation channel of the heat dissipation fins is connected through the air guide component seven and the distribution box.

[0007] In some embodiments, the leakage monitoring unit further includes: A pneumatic cylinder that drives the lifting and lowering of a thin-film humidity sensor; A thin-film humidity sensor is installed in a dry air guide channel one, which is connected to an air guide channel three.

[0008] In some embodiments, the piston end of the pneumatic cylinder is connected to the support frame four, and the thin-film humidity sensor is embedded on the outside of the support frame four; the air guide groove one is opened inside the support frame two, and its two ends are connected to the air guide component two.

[0009] In some embodiments, the airflow circulation system further includes: An inflatable expansion component that is connected to the air guide component; A three-way valve and a solenoid valve for controlling the air pressure of the inflation expansion component.

[0010] In some embodiments, the inflatable expansion member is connected to the flow box via an air guide bend; The normally closed end of the three-way valve is connected to the flow guide box, and the normally open end is connected to the air guide component five.

[0011] In some embodiments, the second support frame is magnetically fixed to the oil circuit board by an electromagnet; The sponge block is fixed inside the detachable support frame three, which is installed inside the support frame two.

[0012] In some embodiments, the electromagnet has a circular groove, and the limiting shaft is inserted into the circular groove and fixed to the support frame.

[0013] In some embodiments, an air guide groove 2 is formed on the outer wall of the air guide component 5; The top of the second air guide groove is connected to the fourth air guide component, and the bottom is connected to the seventh air guide component. After the air guide groove three is rotated 180°, it can be connected to either the air guide component four or the air guide component seven, and the airflow is guided to the exhaust port of the diversion box through the air guide component seven.

[0014] In some embodiments, an air guide groove 3 is formed on the outer wall of the air guide member 6; The outer wall of the air guide component five is provided with corresponding air guide groove two, and the airflow channel is switched by aligning the air guide groove three with the air guide groove two.

[0015] A leakage monitoring method based on a hydraulic support for a paste-filled template includes: S1. Leakage Detection: A thin-film humidity sensor embedded in a sponge block detects hydraulic oil adsorption at the connection point; an alarm is triggered and the water outlet is located based on the humidity exceeding the standard signal; S2. Thin-film humidity sensor reset and drying: The pneumatic cylinder is activated to retract, moving the thin-film humidity sensor into the air guide slot one; the forward and reverse motors are controlled to drive the air guide component six to rotate to the first position; and the air guide component five delivers a drying airflow to the air guide slot one.

Airflow mode switching: Normal mode: the air guide six rotates to the second position, and the cooling airflow of the cooling chip is directed to the heat dissipation fins; Leakage response mode: automatically switches to the first position when S2 is executed.

[0016] Compared with the prior art, the present invention has the following beneficial effects: When this application is used, the thin-film humidity sensors fixedly embedded on the four outer sides of the support frame are inserted into the inside of the sponge block. After the oil content inside the sponge block increases, the humidity value detected by the thin-film humidity sensor increases. The detection result of the thin-film humidity sensor is fed back to the controller on the hydraulic support of the paste filling template. The controller issues an alarm and displays the water outlet part number corresponding to the sponge block, reminding the staff to quickly locate and repair the potentially leaking hose, thus ensuring the safety of the hydraulic support of the paste filling template.

[0017] When using this application, after replacing the connector and hose, clean the inside of support frame two, and then install the clean support frame three inside support frame two, so that the clean sponge block comes into contact with the connection between the water outlet and the connector or the connection between the hose and the connector, thus completing the leak repair work.

[0018] When this application is used, a leak monitoring structure is quickly established at the connection between the water outlet and the connector, and at the connection between the hose and the connector through the cooperation of the support frame three, sponge block, air cylinder, support frame four, and thin film humidity sensor. This ensures that leaks in multiple hoses can be monitored and located, reducing the need for staff to locate, inspect, and replace leaking hoses. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but 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.

[0021] A hydraulic support for a paste filling template used in paste filling coal mining includes a paste filling template hydraulic support 1 and a hydraulic integrated module 2 installed on the paste filling template hydraulic support 1. The hydraulic integrated module 2 includes an oil circuit board 3, heat dissipation fins 5 and multiple water outlet components 6.

[0022] like Figure 2 and Figure 3 Support frames 4 are fixedly installed on both sides of the bottom of the hydraulic integrated module 2. The support frames 4 are used to fix the hydraulic integrated module 2 into the hydraulic support 1 of the paste filling template. Multiple heat dissipation fins 5 are fixedly installed at the bottom of the hydraulic integrated module 2. The heat dissipation fins 5 extend into the hydraulic integrated module 2 and the oil circuit board 3. The heat dissipation fins 5 guide the heat inside the hydraulic integrated module 2 and the oil circuit board 3 to dissipate. Multiple water outlets 6 are fixedly installed on one side of the oil circuit board 3. Half of the water outlets 6 are set in the upper part and the other half of the water outlets 6 are set in the lower part. The upper water outlets 6 correspond one-to-one with the lower water outlets 6. Connectors 7 are threaded inside the water outlets 6. A hose 8 is fixedly installed at one end of the connector 7. The hose 8 located at the top is a high-pressure hose and the hose 8 located at the bottom is a low-pressure hose. Multiple hoses 8 provide support for the operation of various hydraulic equipment in the hydraulic support 1 of the paste filling template.

[0023] Each water outlet component 6 is equipped with a leakage monitoring unit. The leakage monitoring unit includes: a support frame 2 11 located at the bottom of the water outlet component 6; a sponge block 14 movably installed inside the support frame 2 11; and a thin-film humidity sensor 27 embedded in the sponge block 14.

[0024] It also includes an airflow circulation system, which comprises: air guide component 5 30: connected to all leakage monitoring units, used to deliver airflow; air guide component 6 32: rotatably installed inside air guide component 5 30, with air guide groove 3 33 opened on its outer wall; cooling plate 48: embedded in the inner wall of air guide component 6 32, used to cool the airflow; forward and reverse motor 39: drives air guide component 6 32 to rotate, so that one of the air guide grooves 3 33 is connected: first position: connected to the air guide channel of the leakage monitoring unit, used for drying the thin film humidity sensor 27; second position: connected to the heat dissipation channel of the heat dissipation fin 5, used for forced heat dissipation.

[0025] The leak monitoring unit also includes: a pneumatic cylinder 23 for driving the lifting and lowering of the thin-film humidity sensor 27; and a dry air guide groove 19 for the thin-film humidity sensor 27 to be placed in.

[0026] The airflow circulation system also includes: an inflation expansion member 42 connected to the air guide member 32; and a three-way valve 47 and a solenoid valve 44 for controlling the air pressure of the inflation expansion member 42. The inflation expansion member 42 is connected to the flow guide box 43 through the air guide bend 41; the normally closed end of the three-way valve 47 is connected to the flow guide box 43, and the normally open end is connected to the air guide member 30.

[0027] In a specific embodiment, an electromagnet 9 and a support frame 2 11 are provided at the bottom of the outer side of the water outlet 6. A sponge block 14 is provided inside the support frame 2 11. A thin film humidity sensor 27 is provided on one side of each of the multiple support frames 2 11. Two air guides 3 28 are provided between two adjacent thin film humidity sensors 27 in the vertical direction. An air guide 5 30 is connected between the multiple thin film humidity sensors 27 located at the bottom. An exhaust gas utilization component is connected to the outside of the air guide 5 30. An air guide 6 32 is rotatably installed inside the air guide 5 30. Multiple cooling chips 48 are fixedly embedded inside the air guide 6 32. An air guide bend 41 is rotatably connected inside the air guide 6 32. An inflation expansion component 42 is fixedly connected to the outside of the air guide bend 41. An air supply component is provided between the air guide 5 30 and the air guide bend 41.

[0028] like Figure 5 and Figure 6As shown, the electromagnet 9 is fixedly installed on one side of the oil circuit board 3 and cannot move. Multiple circular slots 10 opened on one side of the electromagnet 9 are each fitted with a limiting shaft 12. The limiting shaft 12 is fixedly connected to the second support frame 11. The electromagnet 9 works by magnetic force attracting and fixing the iron support frame 11. At the same time, the multiple limiting shafts 12 increase the stability of the installation between the second support frame 11 and the electromagnet 9. Support frame 3 13 is movably installed inside support frame 2 11. By aligning support frame 3 13 with the preset track on support frame 2 11, support frame 3 13 can be pushed into the installed support frame 2 11. Support frame 3 13 and support frame 2 11 are in an interference fit state. Only when a certain amount of force is applied to support frame 3 13 can it move. Sponge block 14 is fixedly installed inside support frame 3 13. Sponge block 14 is set at the bottom of the connection between water outlet 6 and connector 7 and the connection between hose 8 and connector 7. The connection between water outlet 6 and connector 7 is prone to leakage due to the interaction of high-pressure hydraulic oil flow, structural aging, structural cracking, etc. The connection between hose 8 and connector 7 is prone to cracking and leakage due to the movement of hose 8. Sponge block 14 absorbs the leaked hydraulic oil, preventing hydraulic oil from flowing into the support and causing slipperiness, which would threaten the safety of workers and reduce the occurrence of accidents.

[0029] like Figure 10 As shown, the piston end of the pneumatic cylinder 23 is connected to the support frame 4 20, and the thin-film humidity sensor 27 is embedded on the outside of the support frame 4 20; the air guide groove 19 is opened inside the support frame 2 11, and its two ends are connected to the air guide component 2 16.

[0030] In specific embodiments, such as Figure 8 As shown, two air guide components 2 16 are fixedly installed on one side of the support frame 2 11. The two air guide components 2 16 are connected by an air guide component 1 15. A partition block 18 is fixedly installed inside the air guide component 1 15, which separates the interior of the air guide component 1 15. An installation pipe 21 is provided between the air guide component 1 15 and the support frame 2 11. The two air guide components 2 16 and the installation pipe 21 are respectively connected to the interior of the air guide groove 19 opened in the support frame 2 11.

[0031] The separator 18 is positioned between the two air guides 16 to prevent communication between them via the air guide 15. For example... Figure 3 , Figure 5 , Figure 7 , Figure 8 As shown, the two air guides 15 in the two adjacent leakage monitoring units in the vertical direction are connected by two air guides 28 on the left and right sides. Both air guides 16 have multiple filter screens 17 fixedly installed inside. The setting of the filter screens 17 results in a slower airflow velocity inside the air guide 16, and a slower airflow velocity into the air guide groove 19.

[0032] like Figure 7 As shown, the bottom air guide 15 is connected to the air guide 5 30 via the air guide 4 29 at its front side. After high-pressure gas is delivered into the bottom air guide 15 via the air guide 4 29, part of the gas enters the adjacent air guide groove 19 through the air guide 2 16 fixedly installed at the front side of the bottom air guide 15. The other part of the gas enters the upper air guide 15 through the air guide 3 28 at the front side, and finally enters the upper air guide groove 19 through the air guide 2 16 installed at the front side of the upper air guide 15. A one-way valve 35 is fixedly connected to the bottom rear side of the bottom air guide 15. The airflow in the two air guide grooves 19 enters the one-way valve 35 through the rear air guide 3 28 and the two air guide 2 16. Figure 11 ).

[0033] In summary, the high-speed airflow delivered from the air guide component 5 30 to the air guide component 4 29 flows through the two air guide slots 19 under the action of the two adjacent leakage monitoring units in the vertical direction, and is then discharged through the one-way valve 35. Due to the one-way conduction characteristic of the one-way valve 35, the airflow discharged through the one-way valve 35 cannot return to the air guide slot 19.

[0034] like Figure 8 , Figure 9 and Figure 10 As shown, a pneumatic cylinder 23 and a telescopic rod 24 are installed inside the mounting pipe 21. The outer shells of the pneumatic cylinder 23 and the telescopic rod 24 are fixedly connected to the air guide component 15. A support frame 5 25 is fixedly installed between the piston end of the pneumatic cylinder 23 and the piston end of the telescopic rod 24. The support frame 5 25 is fixedly connected to the support frame 4 20. The support frame 5 25 and the support frame 4 20 move synchronously. A thin-film humidity sensor 27 is fixedly embedded on the outside of the support frame 4 20 and is located inside the air guide groove 19. One end of the support frame 4 20 passes through the support frame 2 11 and the support frame 3 13, and the outside of the support frame 4 20 is in close contact with the support frame 3 13 and the support frame 2 11. During the movement of the support frame 4 20, the outer wall of the support frame 4 20 is cleaned by the support frame 3 13 and the support frame 2 11, and the outer wall of the thin-film humidity sensor 27 is cleaned by the support frame 3 13 and the support frame 2 11.

[0035] like Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, in the waste gas utilization component, multiple air guide components 34 are fixedly installed on the bottom outer side of the air guide component 30. A diversion box 37 is fixedly installed between the multiple air guide components 34. The diversion box 37 has multiple exhaust holes 38 on the side facing the multiple heat dissipation fins 5. An air guide component 36 is fixedly installed between the air guide component 34 and the adjacent one-way valve 35. The airflow discharged through the one-way valve 35 enters the interior of the air guide component 34.

[0036] Air guide component 4 29 corresponds to air guide component 7 34. Air guide component 4 29 and air guide component 7 34 are both provided with air guide groove 2 31 at the bottom and air guide groove 2 31 at the top. Air guide groove 2 31 is opened on the outside of air guide component 5 30. Air guide groove 3 33 is provided at the bottom of air guide groove 2 31 at the top. Air guide groove 3 33 is opened on the outside of air guide component 6 32. An internal thread mounting seat 40 is installed inside the hydraulic support 1 of the paste filling template by thread. A forward and reverse motor 39 is fixedly installed on the internal thread mounting seat 40. The output end of the forward and reverse motor 39 extends into the air guide component 5 30 and is fixedly connected to air guide component 6 32.

[0037] After controlling the forward and reverse motor 39 to rotate forward for a period of time, the forward and reverse motor 39 drives the air guide component 6 32 to rotate 180°. After the air guide groove 33 of the air guide component 6 32 is aligned with the upper air guide groove 2 31, the interior of the air guide component 6 32 is connected to the interior of the air guide component 4 29, and the gas inside the air guide component 6 32 enters the interior of the air guide component 4 29. After controlling the forward and reverse motor 39 to rotate in reverse for a period of time, the forward and reverse motor 39 drives the air guide component 6 32 to rotate in reverse 180°. After the air guide groove 33 of the air guide component 6 32 is aligned with the lower air guide groove 2 31, the interior of the air guide component 6 32 is connected to the interior of the air guide component 7 34, and the gas inside the air guide groove 33 directly enters the interior of the air guide component 7 34.

[0038] like Figure 12 , Figure 13 and Figure 14 As shown, one end of the air guide bend 41 extends to the outside of the air guide component 5 30. The outer wall of the air guide bend 41 is fixedly connected to the air guide component 5 30. One end of the air guide bend 41 is rotatably connected to the air guide component 6 32. Therefore, the rotation of the air guide component 6 32 will not be affected by the air guide bend 41.

[0039] The mounting box 45 is fixedly installed at one end of the air guide component 30. The mounting box 45 is fixedly installed at the normally open end of the three-way valve 47. The air pump 46 is installed inside the hydraulic support 1 of the paste filling template through a threaded structure. The three-way valve 47 is fixedly installed at the air outlet end of the air pump 46. A flow guide box 43 is fixedly installed on one side of the normally closed end of the three-way valve 47. A solenoid valve 44 is fixedly installed on one side of the flow guide box 43. One end of the air guide bend 41 is fixedly connected to the flow guide box 43.

[0040] A method for monitoring leakage in a hydraulic support for a paste filling template, comprising: S1. Leakage Detection: Hydraulic oil adsorption at the connection point is detected by a thin-film humidity sensor 27 embedded in the sponge block 14; The controller alarms and locates water outlet component 6 based on the humidity exceeding the standard signal; S2. Thin-film humidity sensor 27 Reset drying: The pneumatic cylinder 23 is activated to retract, moving the thin-film humidity sensor 27 into the air guide groove 19. Control the forward and reverse motors 39 to drive the air guide component 32 to rotate to the first position; Dry airflow is delivered to air duct 19 via air guide component 530; S3. Maintenance and Replacement: Release the magnetic attraction of electromagnet 9 to support frame 211; Disassemble and replace the support frame 313 and the sponge block 14; The control cylinder 23 extends to allow the sensor to re-insert into the sponge block 14; S4. Airflow mode switching: Normal mode: Air guide component 6 32 rotates to the second position, cooling airflow from cooling chip 48 is directed to heat dissipation fins 5; Leakage response mode: Automatically switch to the first position when executing S2.

[0041] Specifically, the safety monitoring system operates as follows: Under normal conditions, the interior of air guide component 6 32 is connected to the interior of multiple air guide components 7 34. Air pump 46 delivers high-speed gas to air guide component 5 30 and air guide component 6 32 through the normally open end of three-way valve 47 and mounting box 45. High-speed airflow is delivered to the interior of multiple air guide components 7 34 through air guide component 6 32. The high-speed gas enters multiple positions inside the distribution box 37 through multiple air guide components 7 34. Under the guidance of the distribution box 37, the high-speed airflow is discharged to multiple heat dissipation fins 5 through multiple exhaust holes 38, enhancing the heat dissipation effect of heat dissipation fins 5 on the interior of hydraulic integrated module 2. Multiple cooling plates 48 fixedly installed inside air guide component 6 32 are controlled to work for a period of time. The cooling plates 48 work to cool, and the airflow inside air guide component 6 32 is cooled down, further increasing the heat dissipation effect of hydraulic integrated module 2.

[0042] When the hydraulic integrated module 2 controls the various hydraulic devices in the hydraulic support 1 of the paste filling template, high-pressure hydraulic oil flows inside the hose 8, and the sponge block 14 is set at the connection between the water outlet 6 and the connector 7, where oil leakage is likely to occur, as well as at the bottom of the connection between the hose 8 and the connector 7.

[0043] If a leak occurs at the connection between the water outlet 6 and the connector 7, or at the connection between the hose 8 and the connector 7, where the sponge block 14 is located, the sponge block 14 absorbs the leaked hydraulic oil, increasing the oil content inside the sponge block 14. The thin-film humidity sensor 27, fixedly embedded on the outside of the support frame 4 20, is inserted into the sponge block 14. After the oil content inside the sponge block 14 increases, the humidity value detected by the thin-film humidity sensor 27 increases. The detection result of the thin-film humidity sensor 27 is fed back to the controller on the hydraulic support 1 of the paste filling template. The controller issues an alarm and displays the location of the sponge block. The water outlet part number 6 corresponding to 14 reminds the staff to quickly locate and repair the potentially leaking hose 8, ensuring the safety of the hydraulic support 1 for the paste filling template; and the air cylinder 23 on one side of the thin-film humidity sensor 27 that detects the change in humidity value works. The air cylinder 23 works and contracts, driving the support frame five 25 and support frame four 20 to move. The thin-film humidity sensor 27 enters the air guide groove one 19. The support frame four 20 is flush with the inner wall of the support frame two 11, blocking the communication between the inside of the air guide groove one 19 and the inside of the support frame two 11, and the support frame three 13 is released from fixation.

[0044] The staff, after being alerted, push the support frame 313 out of the support frame 21. If manual inspection reveals that the leak is caused by a rupture at the connection between the water outlet 6 and the connector 7 or the connection between the hose 8 and the connector 7, resulting in increased humidity in the sponge block 14, or if the hose 8 is damaged, causing some hydraulic oil to move along the outer wall of the hose 8 and be absorbed by the sponge block 14, resulting in increased humidity in the sponge block 14, then the connector 7 and the hose 8 are replaced. After cleaning the inside of the support frame 21, the clean support frame 313 is installed inside the support frame 21, so that the clean sponge block 14 comes into contact with the connection between the water outlet 6 and the connector 7 or the connection between the hose 8 and the connector 7, thus completing the leak repair work.

[0045] If the staff finds no leakage, they can install a new support frame 3 13 and a sponge block 14 on support frame 2 11.

[0046] Upon receiving the feedback detection result from the thin-film humidity sensor 27, the controller on the hydraulic support 1 of the paste filling template operates, controlling the pneumatic cylinder 23 to contract and allow the thin-film humidity sensor 27 to enter the air guide groove 19. The controller then controls the forward and reverse motors 39 to drive the air guide component 32 to rotate, connecting it to the air guide component 29. High-speed airflow from the air guide component 30 flows through the air guide groove 19, drying the thin-film humidity sensor 27 inside. The side is restored to a dry state; after the new support frame 13 and sponge block 14 are replaced, the controller controls the pneumatic cylinder 23 to work, and the thin film humidity sensor 27 is inserted into the new sponge block 14. Through the cooperation of the support frame 13, sponge block 14, pneumatic cylinder 23, support frame 20 and thin film humidity sensor 27, a leak monitoring unit is quickly established at the connection between the water outlet 6 and the connector 7 and the connection between the hose 8 and the connector 7, so as to ensure the monitoring and location of leaks in multiple hoses 8, and reduce the need for staff to locate, inspect and replace leaking hoses 8.

[0047] When the thin-film humidity sensor 27 is reset, the forward and reverse motor 39 is controlled to reverse, and the air guide 6 32 is restored to the state of being connected with the air guide 7 34.

[0048] The normally closed end of the three-way valve 47 is opened, allowing the air pump 46 to deliver gas into the guide box 43 through the three-way valve 47. The gas is then delivered to the inflation expansion member 42 through the guide box 43 and the air guide bend 41. The inflation expansion member 42 expands, filling the internal space of the air guide member 6 32 and increasing the internal air pressure. This achieves the effect of increasing the internal air pressure of the air guide member 6 32 without increasing the working power of the air pump 46. The solenoid valve 44 is then opened to release the pressure inside the inflation expansion member 42.

[0049] Separate the internal thread mounting base 40 from the hydraulic support 1 of the paste filling template, separate the air pump 46 from the hydraulic support 1 of the paste filling template, and control the multiple electromagnets 9 to stop working. Then the safety monitoring system can be separated from the oil circuit board 3, and the hydraulic integrated module 2 can be maintained according to the plan.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
