[0041] The following further elaborates on the detailed implementation manners of the present invention in conjunction with the accompanying drawings.

[0042] As Figure 1 、 Figure 2As shown, a pressure-maintaining test control system for multiple types of pressure monitoring instruments for mining is provided. As an independent pressure-maintaining measurement and control system, this system is separately set up as a mining pressure instrument test center, and its operating area should be about 200 square meters to 300 square meters. This system includes at least two sets of cabinet-type pressure-maintaining devices 1, and each set of cabinet-type pressure-maintaining devices 1 is respectively installed with 40 mining pressure instruments III 15 and 40 mining pressure instruments IV 16. The open side of the cabinet-type pressure-maintaining device 1 without a sealed plate is placed against the wall, and the side with the side door faces inward. The cabinet-type pressure-maintaining device 1 is provided with a connecting pipeline 101 and a bench pipeline 103, wherein the pipe valve oil pipe access end of the bench pipeline 103 connected to the cabinet-type pressure-maintaining device 1 is opposite to the system power source, namely the hydraulic pump station 2 and the electro-hydraulic control platform 3. The hydraulic pump station 2 and the electro-hydraulic control platform 3 are arranged side by side along the wall in the left and right directions, and at least two sets of office operation platforms 4 are arranged along the wall on the right side of the electro-hydraulic control platform 3. At least two sets of frame-type pressure-maintaining support devices 5 and mobile pressure-maintaining support devices 6 are arranged in parallel in the left and right directions on the right side of the platform 4. The frame-type pressure-maintaining support devices 5 and the mobile pressure-maintaining support devices 6 are used in pairs. The mobile pressure-maintaining support device 6 is located on the side and lower side of the frame-type pressure-maintaining support device 5. A mine pressure meter I8 is installed on the mobile pressure-maintaining support device 6, and mine pressure meters II9 of different models are installed on the frame-type pressure-maintaining support device 5. When the mobile pressure-maintaining support device 6 is connected to the mine pressure meter I8, it can be moved a proper distance to facilitate the installation of the meter. After the interface is fixed, it can be pushed into the side and lower side of the frame-type pressure-maintaining support device 5 by a push wheel to effectively utilize the space area and increase the channel area.

[0043] In order to facilitate the connection of external connection pipelines, the cabinet-type pressure-maintaining device 1, the frame-type pressure-maintaining support device 5 and the mobile pressure-maintaining support device 6 are placed side by side horizontally, and are respectively connected to the hydraulic pipeline system 7 on the outside. The other end of the hydraulic pipeline system 7 is connected to the hard pipe hydraulic pipeline of the seamless pipe from the pipeline interface of the hydraulic pump station 2 and the electro-hydraulic control platform 3. The hard pipe is arranged along the wall to the branch pipeline of each pressure-maintaining device, and then connected to the straight or three-way valve interface of each support through a hose connection pipeline. The pipeline direction is arranged on the bottom side of the support or equipment and facilities as much as possible, avoiding the main passage of the working area. The hydraulic pump station 2, the electro-hydraulic control platform 3, and the office operation platform 4 are placed side by side against the wall inside the frame-type pressure-maintaining support device 5, which is conducive to the operation and control of the main process, convenient for pipeline connection, and also conducive to the effective use of the working area.

[0044] The hydraulic pipeline system 7 refers to the pipeline connection between the hydraulic pump station 2, the electro-hydraulic control platform 2 and each support and bench test instrument in the system, including the hard connection pipeline part and the soft connection pipeline part. The hard connection pipeline mainly uses seamless stainless steel pipes, and the soft connection pipeline mainly uses high-pressure hydraulic rubber hoses, as well as welded joints, butt screw heads, quick-change joints, control valves, etc. in the pipeline. For those that can be controlled together in multiple paths, series branches are adopted, and for those that are controlled separately in multiple paths, parallel branches are adopted. Except for the monitoring instruments on the console, high-precision electronic test instruments are also installed at the terminals of the connecting pipelines. The hard connection pipeline is laid at the bottom of the device near the wall in a position that is not easy to move, and the soft connection pipeline is connected to the straight-through or three-way valve position on the side of the support device. The hard pipe and the rubber hose are connected through a connecting butt screw head, and a sealing ring is added for sealing.

[0045] On the inner side of the wall opposite to the wall where the hydraulic pump station 2 is set, a dressing cabinet 13, a washbasin 12 and a product turnover and test area 17 are arranged in sequence from left to right. The product turnover and test area 17 includes a turnover trolley 11 and a customized shelf 10; a mine pressure instrument test and sorting platform 14 is installed between the two walls. In this embodiment, two mine pressure instrument test and sorting platforms 14 are placed side by side, with a length of 2.5 meters. Their main functions are to sort and use the instruments after pressure relief or temporarily place the test instruments to be connected. They are placed in a position with a relatively spacious flat space, and cannot affect the normal connection, testing, disassembly of instruments, etc. of each support device. Sufficient working space should be left around them, generally not less than 0.5 meters, and cannot affect the circulation of the main passage in the operation area. The product turnover and test area 17 is located at an appropriate distance from the frame-type pressure-holding support device 5, about 1 meter, and is arranged against the wall. The temporarily stored turnover trolley 11 and customized shelf 10 are placed 2 - 6 pieces according to the number of production and test instruments. In this embodiment, 4 pieces are placed on the turnover trolley 11 and 4 pieces are placed on the customized shelf 10; the dressing cabinet 13 and the washbasin 12 are arranged on both sides of the indoor entrance of the test site, and the quantity is configured according to the need to facilitate the use during the test work.

[0046] Such as Figure 3As shown in the figure, the frame-type pressure-holding support device 5 includes a frame-type pressure-holding support 501 and a support pipeline 502 installed on the frame-type pressure-holding support 501 through a snap ring fixing seat. The frame-type pressure-holding support 501 is welded by ordinary metal square pipes with a size of 40 mm x 40 mm, and the control structure size is 2.5 m x 0.66 m x 1.2 m to meet the requirements of a certain number of test instruments, and at the same time, it is convenient for testers to access and disassemble the instruments in a standing state. The stable placement of the instruments, the cleanliness and recycling of hydraulic oil are considered, and a high-precision electronic display instrument is configured to facilitate the accurate control of data during the pressure-holding test stage. A concave groove plate is welded in the upper middle part of the frame-type pressure-holding support 501 to facilitate the collection and recycling of dripping and leaking hydraulic oil; a movable acrylic protective cover is arranged at the top of the pressure-holding support 501, which is beneficial to the cleanliness of the oil, the observation of the measurement and control instruments during the test, and the safety and hygiene of the test site. For the convenience of operation, the protective cover is designed into a square groove shape or a semi-circular shape according to the outer top structure of the pressure-holding support 501, and according to the actual situation of the site, a hydraulic cylinder or a gas circuit is used to control the lifting to reduce the manpower. The support pipeline 502 is a hydraulic hose assembly that matches the number of test instruments. It is connected to the metal hard pipe through a connecting screw head, and then the hydraulic pipeline is fixed on the frame-type pressure-holding support 1 through a snap ring fixing seat (8 pieces / 4 pieces on each side).

The left-side oil pipe assembly 503 and the right-side oil pipe assembly 504 are made of stainless steel seamless steel pipes, with holes drilled in the pipe walls and welded and matched with connecting transition screw heads. The ends of the left and right stainless steel seamless steel pipes are welded and sealed with steel plates. The longitudinal hydraulic hose assembly 506 is matched with the transition screw head through a threaded connection; the longitudinal hydraulic hose assembly 506 and the ends of the left-side oil pipe assembly 503 and the right-side oil pipe assembly 504 are respectively installed with three-way valve joints, and the two three-way valves are connected together through a high-pressure hose 507. The entire support pipeline is fixed on the frame-type pressure-holding support 501 through a pipe clamp support. One end of the transverse hydraulic hose assembly 507 of the support pipeline is provided with a quick connector, and the quick connector is connected to the access mine pressure instrument II 9. After the connection is in place, the quick connector is fixed to the access mine pressure instrument II through a mining U-shaped card 505, and all the connected mine pressure instruments II 9 are sequentially placed on the U-shaped groove card plate on the upper part of the frame-type pressure-holding support 501. In this implementation case, the U-shaped groove card plate is a steel plate bending part, and the mining U-shaped card 505 is an externally purchased standard part. An external high-pressure hose is installed at the lower joint of the three-way valve joint.

The cabinet-type pressure maintaining bench 102 adopts a box-frame structure and also includes a platform frame assembly, a side door, a support plate, a baffle, and a bottom plate. The platform frame is welded with 40 mm x 40 mm square pipes, and the support plate is bent from a metal thin plate with holes drilled on the upper plane. The size, quantity, connection method of the holes are matched with the mine pressure instruments of the corresponding pressure measurement types. This implementation case is a drilled cabinet-type pressure maintaining bench 102. The bench pipeline includes a hydraulic oil dredging pipe, a hydraulic hose assembly, a straight-through valve, a three-way valve, a pipe joint, a precision digital display instrument, and mining U-shaped clamps and pipe clamp supports. The connecting pipeline 101 is fixedly connected to the profile side wall inside the box frame of the cabinet-type pressure maintaining bench 102 by a pipe clamp support in a welded manner. A quick-connector part is arranged on the connecting pipeline 101, and the quick-connector part is connected to the transition connector of the hole on the upper panel of the cabinet-type pressure maintaining bench 102. Among them, the box frame is assembled and welded with 40 mm x 40 mm metal square pipe profiles, and the hydraulic oil pipe of the bench pipeline is laid on the inner side wall of the metal square pipe profile through a pipe clamp support. A connecting joint 104 is arranged above the cabinet-type pressure maintaining bench 102, and the connecting joint 104 is welded to the port of the drilled wall of two metal pipes of the bench pipeline 103. In this implementation case, there are two rows of 20 connecting joints 104 arranged above the cabinet-type pressure maintaining bench 102. Each row of 10 pieces is respectively connected to a hydraulic oil metal pipe on the bench pipeline 103 in a welded form. To ensure the smooth flow of the oil circuit, there are holes in the middle of the connecting joint 104, and the holes in the middle of the connecting joint 104 are connected to the drilled holes at the welding place of the hydraulic oil metal pipe. The other end of the connecting joint 104 is connected to the high-pressure hose quick-connector through a control joint 105. The bench pipeline 103, the connecting joint 104, and the control joint 105 are connected to the corresponding interfaces of the external connecting pipeline and the hydraulic pump station 2. An active acrylic protective cover is arranged at the top of the cabinet-type pressure maintaining bench 102, which is beneficial to the cleanliness of the oil fluid, also beneficial to observing the measurement and control instruments during the test, and also beneficial to the safety and hygiene of the test site. For the convenience of operation, the protective cover is designed into a square groove shape or a semi-circular arc shape according to the external top structure of various cabinet-type pressure maintaining benches 102.

The pipeline assembly 602 is connected to the accessed mine pressure instrument I 8 through a quick connector, and the oil cylinder 603 is connected to the electro-hydraulic control platform 3. The basic structure and material selection of the mobile pressure-holding support 601 and the pipeline assembly 602 of the mobile pressure-holding support device are basically the same as those of the frame-type pressure-holding support 501 and the support pipeline 502, except that the external dimensions are adjusted, and a universal wheel mechanism with a locking mechanism is installed at the bottom of the mobile pressure-holding support 601 to facilitate the flexible movement of the support. The mobile top shield 604 is made of acrylic high-transparency board, which is not only beautiful and tidy, but also convenient for observation during the instrument test, and is also beneficial to the cleanliness of the hydraulic oil remaining on the panel. The mobile top shield 604 is lifted and opened through the oil cylinder 603. Before and after the mine pressure instrument I 8 is accessed, the lifting and lowering of the oil cylinder 603 are controlled by the oil circuit valve on the electro-hydraulic control platform 3. The electro-hydraulic control platform 3 is provided with a multi-way control valve, and each pressure-holding support device can control the number of test instruments connected to the system by setting on-off valves at different positions in the hydraulic pipeline connected to it. By opening and closing different control valves, the hydraulic oil flows into different numbers of pressure-holding instrument interfaces, realizing the flexible control of the number of measurement and control instruments to meet the temporary, emergency, and variable measurement and control situations of certain instruments during production and sales processes.

[0050] As Figure 8 shown, the hydraulic pump station 2 selects an upper-mounted vertical medium and small-sized hydraulic pump station, which includes a channel-shaped plate 201. A fuel tank 202 is arranged on the channel-shaped plate 201. At one end of the top surface of the fuel tank 202, an inverted motor assembly 208 is arranged. The bottom of the motor assembly 208 passes through the fuel tank 202 through a coupling assembly 207 and is connected to a filter and oil pump assembly 203. The motor assembly 208 is vertical and is placed on the top surface of the fuel tank 202. At the other end of the top surface of the fuel tank 202, an oil circuit valve block assembly 205 is arranged. The oil circuit valve block assembly 205 is connected to an electric contact pressure gauge 206 through a pipeline. A liquid level gauge 204 is arranged on the front side of the fuel tank 202. The channel-shaped plate 201 at the bottom of the hydraulic pump station 2 is made into a channel shape and is welded to the four peripheral plates of the fuel tank 202, which is convenient for the collection, recovery, and temporary storage of dripping and leaking oil during the pipeline disconnection and connection process, and is convenient for ground cleaning. The fuel tank 202 is made of Q235A steel plates with a thickness of 3 mm and welded together. A circular hole with a diameter of φ350 mm is opened on one side, and it is threadedly connected to the side vertical plate of the fuel tank 202 through a circular flange plate, which is convenient for cleaning, washing, and rapid discharge of the oil medium in the fuel tank 202. Oil ports are arranged at the corners of the upper plane of the fuel tank 202, and filter meshes are placed, and quick-turning snap covers are used. The oil circuit valve block assembly 205 is connected to the corresponding interfaces of the electro-hydraulic control platform 3 for each oil circuit interface. For the convenience of operation, a manual regulating valve is provided as a spare on the top surface of the hydraulic pump station.

[0051] To ensure the stable performance of the system during long-term operation, a tubular water cooler is used for circulating cooling of the hydraulic oil temperature control in the hydraulic pump station 2. The oil supply of the hydraulic pump station 2 is regulated by an adjustable overflow valve to adjust the system pressure, and the pressure gauge shows the pressure value until the working requirements are met. The solenoid valve realizes functions such as boosting pressure, returning stroke, and pressure relief through commutation to meet the requirements of various working conditions. The overflow valve plays a reliable overload protection role to ensure that the hydraulic pipeline and the motor are not damaged due to pressure overload. The unit of the pressure gauge indication is MPa / KN. The outer circle of the pressure gauge dial is 0 - 60 MPa, corresponding to an approximate outer circle indication of 0 - 300 KN, which is convenient for querying, displaying, or comparing the parameters of different indication units in system measurement and control. The operator adjusts according to needs. When the return magnet is energized, the pressure shown on the pressure gauge is the actual working pressure. Turning the handwheel of the overflow valve clockwise increases the system pressure, and vice versa, the system pressure decreases. When adjusting, the handwheel should be turned slowly to prevent damage to the components of the pressure system.
