Description

Technical Field

[0001] This invention relates to the field of hydraulic fracturing technology, specifically a fracturing pipeline system for detecting the effect of hydraulic fracturing in coal mines. Background Technology

[0002] Hydraulic fracturing in coal mines involves drilling boreholes into rock formations underground or on the surface, and then using a high-pressure pump to inject fracturing fluid into the boreholes through a high-pressure fracturing pipeline system. This forces the fluid to create fractures and open up the rock. The fracturing pipeline system is the core construction carrier for achieving high-pressure fluid transport and completing underground fracturing modifications. Monitoring the distribution of fractures during fracturing is crucial. To monitor the fracture distribution in real time, the industry commonly employs microseismic monitoring technology. This involves using seismic detectors in conjunction with intelligent monitoring units. The seismic detectors are connected to the intelligent monitoring units to monitor the process. The seismic detectors are fixed to the rock wall to collect microseismic signals from the fracturing process. These signals are then transmitted to an intelligent monitoring unit, which in turn transmits the information to a ground-based monitoring host. The host uses specialized software to pick up, identify, locate, and invert the signals, automatically calculating the fracture conditions during the fracturing process and dynamically evaluating the fracturing effect. However, multiple seismic detectors need to work together in a spatial array to accurately invert the location and morphology of the fractures. They are usually arranged in a rectangular array. The seismic detectors are typically fixed to the rock wall using supports to keep them horizontal. Installation is usually done manually, which is a cumbersome and inconvenient process. Summary of the Invention

[0003] The purpose of this invention is to provide a fracturing pipeline system for detecting the effect of hydraulic fracturing in coal mines, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A fracturing pipeline system for detecting the effect of hydraulic fracturing in coal mines, comprising: The system includes a mobile platform, a U-shaped frame, multiple support mechanisms for installation on the rock surface, an adjustment mechanism for adjusting the height of the support mechanisms, and multiple installation mechanisms to assist in the installation of the support mechanisms. The mobile platform has multiple casters on its bottom surface. One end of each arm of the U-shaped frame is fixedly connected to the top surface of the mobile platform. Slide grooves are provided on opposite sides of the U-shaped frame. The adjustment mechanism is located on one side of the U-shaped frame and includes a moving frame with guide grooves on opposite sides. Multiple adjustment components are vertically arranged sequentially on opposite sides of the moving frame. Multiple installation mechanisms are located between the two arms of the U-shaped frame, and each installation mechanism is located between two adjacent adjustment components on the same side of the moving frame. Multiple support mechanisms correspond one-to-one with multiple installation mechanisms. Each support mechanism includes an L-shaped plate with multiple circular holes on one side of its short arm. A collar is rotatably fitted inside each of the circular holes, and a positioning screw is movably inserted into each collar. A seismic detector is fixedly installed on one side of the long arm of the L-shaped plate.

[0005] Furthermore, the adjustment components include: The system consists of two frames, four sliding plates, and sliding blocks. Two positioning plates are fixedly fitted inside each of the two vertically arranged frames. Rotating rods connect the two positioning plates on the same frame. Worm gears are fixedly fitted onto the outer walls of the two rotating rods, and main screws are fixedly connected to both ends of the two rotating rods. The four sliding plates are slidably fitted onto both ends of the two frames. An internally threaded cylinder is fixedly fitted onto one end of each of the four sliding plates, and the four internally threaded cylinders are screwed onto the four main screws. A locking block is rotatably connected to one end of one of the two sliding plates closest to the U-shaped frame, and a guide rod is fixedly connected to the other end of the other side of each sliding plate. The two locking blocks are slidably engaged inside adjacent slide grooves. Sleeve holes are opened at the other ends of the two sliding plates furthest from the U-shaped frame. The sliding blocks are located on one side of the two sliding plates furthest from the U-shaped frame, and are slidably engaged inside adjacent guide grooves. Two connecting shafts are fixedly connected to one side of each sliding block, and the two connecting shafts are rotatably fitted into the two sleeve holes.

[0006] Furthermore, worm gears are rotatably connected between the two opposing inner sidewalls of the two sleeves, and one end of each worm gear passes through the adjacent sleeve and is fixedly connected with a screw head. Both worm gears mesh with the adjacent worm wheel.

[0007] Furthermore, the mobile platform has two fixed rails fixedly connected to its two long sides on the top surface, and each fixed rail has a sliding table slidably engaged inside it. Each sliding table has a rail fixedly connected to its top surface, and each rail has a motor box slidably engaged inside it. Each motor box contains a servo motor, and each servo motor shaft is fixedly connected to a retaining sleeve. Each retaining sleeve has a sleeve slidably engaged on its outer wall, and each sleeve is movably engaged with an adjacent screw head.

[0008] Furthermore, the internal cross-section of the sleeve is hexagonal.

[0009] Furthermore, the installation mechanism includes: The system consists of a plate, multiple motor boxes, and two guide rails. The plate is located on the short arm side of the corresponding L-shaped plate. The multiple motor boxes correspond one-to-one with the positioning screws on the adjacent L-shaped plates. Each motor box contains a drive motor, and the motor ends of each drive motor are fixedly connected to a magnetic cylinder. One end of the positioning screw has a notch, and one end of the magnetic cylinder is fixedly connected to a protrusion. The protrusion is movably engaged with the adjacent notch. One end of the positioning screw is movably inserted into the adjacent magnetic cylinder. One end of each of the two guide rails is fixedly connected to one side of the plate. The multiple motor boxes are fixedly connected to the adjacent guide rails via brackets.

[0010] Furthermore, both ends of the plate are rotatably connected to support arms, and one end of each support arm is rotatably connected to a guide plate. Each guide plate has two sliding holes on one side, and the two adjacent guide rods located in the two adjustment components are slidably sleeved inside the two sliding holes. Each adjacent sliding plate located in the two adjustment components is fixedly connected to the guide plate with a tension spring.

[0011] Furthermore, there are two columns fixedly connected between the top surface of the U-shaped frame and the top surface of the mobile platform, and pressure plates are fixedly connected between the two guide rails. The two guide rails are slidably engaged with locking cylinders. The two columns are slidably sleeved inside the two locking cylinders. A push plate is provided on one side of the pressure plate, and multiple insert rods are fixedly connected to one side of the push plate. One end of each insert rod passes through the pressure plate, and multiple springs are fixedly connected between the pressure plate and the push plate.

[0012] Furthermore, the mobile platform has multiple connecting frames fixedly connected to its top surface, and multiple placement frames are fixedly connected to one side of each connecting frame. Each placement frame is equipped with a hydraulic cylinder. One connecting frame is equipped with a fixed plate, and the movable ends of multiple hydraulic cylinders on one connecting frame are fixedly connected to the fixed plate. The push plates on multiple mounting mechanisms are also fixedly connected to the fixed plate. The movable ends of the hydraulic cylinders on other connecting frames are fixedly connected to the mobile frame.

[0013] Furthermore, the top surface of the mobile platform is fixedly connected to multiple slide rails, and each slide rail has a slider that is slidably engaged inside it. All sliders are fixedly connected to the bottom surface of the mobile frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are: By using support mechanisms to support the seismic detector, multiple support mechanisms are placed on installation mechanisms at different heights. Then, the spacing between the installation mechanisms is adjusted to regulate the height of the installation mechanisms and ensure that they are equidistantly distributed, thus aligning the support mechanisms with their pre-installation positions on the rock wall. The installation mechanisms are then used to move the support mechanisms to their pre-installation positions at different heights on the rock wall, with varying movement distances to accommodate the unevenness of the rock wall. Finally, the installation mechanisms are used to fix the support mechanisms to their pre-installation positions on the rock wall, thereby improving the installation efficiency of the seismic detector and facilitating its use.

[0015] By drilling holes at pre-installation positions on the rock wall and installing pre-embedded screw sleeves inside the holes at the pre-installation positions, the pre-installation positions on the rock wall are distributed in a rectangular array. Then, the seismic detector is fixed to the long arm of the L-shaped plate, and the positioning screw is passed through the collar on the short arm of the L-shaped plate. The opposing nut is screwed on the positioning screw to fix the collar by clamping the opposing nut, thereby fixing the relative position of the positioning screw and the L-shaped plate. Then, the notched end of the positioning screw is inserted into the magnetic cylinder on the adjacent installation mechanism, so that the notch engages with the protrusion on the magnetic cylinder. The hydraulic cylinder is activated to move the moving frame, which in turn moves all the sliding blocks synchronously. The sliding blocks then rotate against the rod-shaped members on the adjacent adjusting components, which consist of a sleeve and two adjacent sliding plates. This causes the two rod-shaped members on the adjusting components to open in a V-shape. By adjusting the moving distance of the moving frame, the opening angle of the rod-shaped members on the adjusting components is controlled. Two adjacent adjusting components on the same side of the moving frame are connected by guide plates on adjacent mounting mechanisms. When the two rod-shaped members on multiple adjusting components have the same V-shaped opening angle, the opening of the rod-shaped members automatically lifts multiple mounting mechanisms and distributes them equidistantly. Furthermore, the screw head can be engaged with the sleeve, and then the servo motor drives the screw head to rotate through the sleeve and the sleeve. The screw head drives the adjacent main screw to rotate through the worm and turbine. This causes the main screw to move synchronously towards or away from the two sliding plates inside the sleeve, in conjunction with the internal threaded cylinder. This controls the total length of the sliding plates and the sleeve. When the moving frame moves the same distance, the longer the total length of the sliding plates and the sleeve, the smaller the opening angle of the two rod-shaped members on the adjusting components. After multiple installation mechanisms are aligned with the pre-installation points at different heights on the rock wall using the adjustment mechanism, the hydraulic cylinder can be activated to move the fixing plate, which in turn moves multiple push plates. This causes the push plates to move multiple plates in parallel. The plates are limited by the vertical sliding of the clamping cylinder on the column and the translational movement of the clamping cylinder inside the guide rail, preventing the plates from tilting. The plates are also pulled by the support arm to the adjacent tension spring. When the rock wall is uneven at different heights, the pre-installation point on the more protruding rock wall can first contact the positioning screw on the adjacent installation mechanism. As the fixing plate continues to move, the push plate compresses the adjacent rebound spring, causing the other plates to continue moving. This allows the pre-installation point on the more concave rock wall to contact the positioning screw on the adjacent installation mechanism. Then, the drive motor is activated to rotate the adjacent magnetic cylinder, causing the magnetic cylinder to screw the positioning screw into the pre-embedded screw sleeve to complete the installation.

[0018] 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.

[0019] Please see Figures 1-9 In this embodiment of the invention, a fracturing pipeline system for detecting the effect of hydraulic fracturing in coal mines includes: The system comprises a mobile platform 100, a U-shaped frame 200, multiple support mechanisms 500 for installation on the rock surface, an adjustment mechanism 300 for adjusting the height of the support mechanisms 500, and multiple installation mechanisms 400 for assisting in the installation of the support mechanisms 500. The mobile platform 100 has multiple casters mounted on its bottom surface. One end of each arm of the U-shaped frame 200 is fixedly connected to the top surface of the mobile platform 100. The U-shaped frame 200 has sliding grooves on both opposite sides. The adjustment mechanism 300 is located on one side of the U-shaped frame 200 and includes a movable frame 310, with guide grooves on both opposite sides. Multiple adjustment components are arranged vertically on both sides. Multiple installation mechanisms 400 are located between the two arms of the U-shaped frame 200. The installation mechanisms 400 are located between two adjacent adjustment components on the same side of the movable frame 310. Multiple support mechanisms 500 correspond one-to-one with multiple installation mechanisms 400. The support mechanism 500 includes an L-shaped plate 510. Multiple circular holes are opened on the short arm side of the L-shaped plate 510. A collar 530 is rotatably sleeved inside each of the multiple circular holes. A positioning screw 531 is movably inserted inside each collar 530. A seismic detector 520 is fixedly installed on the long arm side of the L-shaped plate 510.

[0020] Specifically, the seismic detector 520 is supported by a support mechanism 500, and the seismic detector 520 is fixed to the rock wall by installing the support mechanism 500 onto the rock wall. During use, holes are manually drilled at predetermined installation positions in a rectangular array on the rock wall, and pre-embedded threaded sleeves are installed inside the holes. The moving platform 100 is moved to the single-row pre-installation position at the predetermined installation position. Then, multiple seismic detectors 520 are fixed to multiple L-shaped plates 510 using connectors. Finally, the positioning screw 531 passes through the collar 530 and is screwed on with two opposing nuts to ensure proper alignment. The nut clamps the collar 530, thereby fixing the position of the collar 530 and the adjacent positioning screw 531. Then, multiple L-shaped plates 510 are placed on multiple mounting mechanisms 400 respectively. Then, the height of multiple mounting mechanisms 400 is adjusted by the adjusting mechanism 300 so that the L-shaped plates 510 on multiple mounting mechanisms 400 are aligned with the pre-installation positions at different heights on the single row of pre-installation positions. Then, the positioning screws 531 on the L-shaped plates 510 are screwed into the pre-embedded screw sleeves in the corresponding pre-installation positions. This can improve the installation efficiency of the seismic detector 520 and facilitate its use by the user. Example 1

[0021] like Figures 2-4 As shown, in this embodiment, the adjustment assembly includes two sleeve frames 320, four sliding plates 330, and sliding blocks 340. Two positioning plates are fixedly fitted inside each of the two vertically arranged sleeve frames 320. Rotating rods 321 are rotatably connected between the two positioning plates on the same sleeve frame 320. Worm gears are fixedly fitted onto the outer walls of the two rotating rods 321, and main screws 322 are fixedly connected to both ends of the two rotating rods 321. The four sliding plates 330 are slidably fitted onto both ends of the two sleeve frames 320. An internally threaded cylinder 331 is fixedly fitted onto one end of each of the four sliding plates 330, and the four internally threaded cylinders 331 are respectively connected to the four main screws 340. The screws 322 are screwed together. The two sliding plates 330 near the U-shaped frame 200 are rotatably connected to one end of each side with a locking block 332 and a guide rod 333 is fixedly connected to the other end of each side. The two locking blocks 332 are slidably engaged in the interior of adjacent sliding grooves. The two sliding plates 330 away from the U-shaped frame 200 are provided with sleeve holes at the other end. The sliding block 340 is located on the side of the two sliding plates 330 away from the U-shaped frame 200. The sliding block 340 is slidably engaged in the interior of adjacent guide grooves. Two connecting shafts 341 are fixedly connected to one side of the sliding block 340. The two connecting shafts 341 are rotatably engaged in the interior of the two sleeve holes respectively.

[0022] In this embodiment, two adjustment components located on the same side of the moving frame 310 and close to each other are connected by adjacent mounting mechanisms 400. Any one of the frames 320 and the sliding plates 330 at both ends of the adjustment components constitute a rod-like member. The two rod-like members and the sliding block 340 in the adjustment components constitute a linkage structure, such that when the moving frame 310 moves the sliding block 340, the two rod-like members connected to the sliding block 340 can open in a V-shape. The locking block 332 located at the bottom of the slide groove is always positioned at the bottom of the slide groove due to the overall weight of the multiple mounting mechanisms 400 and the adjustment mechanism 300. When the moving frame 310 moves, it can... The sliding blocks 340 on all the adjustment components move synchronously, so that the multiple adjustment components are distributed in a V-shape. Since the sliding blocks 340 move the same distance and the locking blocks 332 all move inside the slide groove, the opening angles of the two rod-shaped members of the multiple adjustment components are consistent. The rod-shaped members drive the mounting mechanisms 400 between the adjustment components to move upward by the same distance, so that the multiple mounting mechanisms 400 are evenly distributed. This makes it easy for the multiple mounting mechanisms 400 to be aligned with the single row of pre-installation positions. The distribution spacing of the mounting mechanisms 400 can be adjusted by controlling the opening angle of the two rod-shaped members on the adjustment components, thereby adjusting the height of the multiple mounting mechanisms 400.

[0023] like Figure 1 , Figure 4 and Figure 9 As shown, in this embodiment, worm gears 323 are rotatably connected between the two opposing inner sidewalls of the two sleeve frames 320, and one end of each worm gear 323 passes through the adjacent sleeve frame 320 and is fixedly connected with a screw head. Both worm gears 323 mesh with adjacent worm wheels. Fixed rails 140 are fixedly connected to the two long sides of the top surface of the moving platform 100, and slides are slidably engaged inside the two fixed rails 140. Rails 141 are fixedly connected to the top surfaces of the two slides, and motor boxes 142 are slidably engaged inside the two rails 141. Servo motors are installed inside the two motor boxes 142, and the motor shafts of the two servo motors are fixedly connected to sleeves 143. Sleeves 144 are slidably sleeved on the outer sidewalls of the two sleeves 143, and both sleeves 144 are movably engaged with adjacent screw heads. The internal cross-section of the sleeves 144 is hexagonal.

[0024] In specific implementation, the two servo motors are equipped with a synchronous control system. The servo motors and their supporting synchronous control system are existing technologies and will not be described in detail here. When the two sleeves 320 on the multiple adjustment components are stacked flat, the fixed rail 140 can be moved, and the sleeve 144 can be slid to fit the adjacent hexagonal screw heads. Then, the servo motor is started to drive the adjacent screw heads and worm 323 to rotate through the sleeve 144. This causes the worm 323 to drive the adjacent rotating rod 321 to rotate through the worm wheel. This causes the rotating rod 321 to drive the two adjacent main screws 322 to rotate synchronously. When the main screws 322 rotate, they drive the two sliding plates 330 inside the sleeve 320 to move synchronously towards or away from each other through the engaged internal threaded cylinder 331. This adjusts the total length of the sliding plate 330 and the sleeve 320. When the moving frame 310 moves the same distance, the opening angle of the two rod-shaped parts on the adjustment component can be adjusted by adjusting the total length of the sliding plate 330 and the sleeve 320, thereby assisting in controlling the distribution spacing of the installation mechanism 400.

[0025] like Figures 1-2 and Figures 5-8 As shown, in this embodiment, the mounting mechanism 400 includes a plate 410, multiple motor boxes 420, and two guide rails 440. The plate 410 is located on the short arm side of the corresponding L-shaped plate 510. The multiple motor boxes 420 correspond one-to-one with the positioning screws 531 on the adjacent L-shaped plates 510. Each of the multiple motor boxes 420 is equipped with a drive motor, and the motor ends of the multiple drive motors are fixedly connected to magnetic cylinders 421. One end of the positioning screw 531 has a notch, and one end of the magnetic cylinder 421 is fixedly connected to a protrusion. The protrusion is movably engaged with the interior of the adjacent notch. One end of the positioning screw 531 is movably inserted into the interior of the adjacent magnetic cylinder 421. One end of each of the two guide rails 440 is fixedly connected to one side of the plate 410. The multiple motor boxes 420 are fixedly connected to the adjacent guide rails 440 through brackets. Both ends of the plate 410 are rotatably connected to support arms 430, and one end of each support arm 430 is fixedly connected to the support arms 430. A guide plate 431 is rotatably connected. Two sliding holes are opened on one side of the guide plate 431. Two adjacent guide rods 333 located on the two adjustment components are slidably sleeved inside the two sliding holes. Two adjacent sliding plates 330 located on the two adjustment components are fixedly connected to the guide plate 431 with tension springs 432. Two columns 460 are fixedly connected between the inner top surface of the U-shaped frame 200 and the top surface of the moving platform 100. A pressure plate 442 is fixedly connected between the two guide rails 440. A locking cylinder 441 is slidably engaged inside the two guide rails 440. The two columns 460 are slidably sleeved inside the two locking cylinders 441. A push plate 450 is provided on one side of the pressure plate 442. Multiple insertion rods 451 are fixedly connected to one side of the push plate 450. One end of each insertion rod 451 passes through the pressure plate 442. Multiple rebound springs 452 are fixedly connected between the pressure plate 442 and the push plate 450.

[0026] In practical implementation, the two sliding holes on the guide plate 431 are respectively slidably engaged with two adjacent guide rods 333 on two adjacent adjustment components, so that the guide plate 431 acts as a connector between the two adjustment components. The inner wall of the magnetic cylinder 421 has a magnetic layer, which can attract and fix the positioning screw 531. When in use, the positioning screw 531 is inserted into the magnetic cylinder 421, so that the notch on the positioning screw 531 is embedded in the protrusion of the magnetic cylinder 421. When the adjustment mechanism 300 is used to adjust multiple installation mechanisms 400 The height is adjusted so that multiple installation mechanisms 400 are equidistantly distributed. By moving the push plates 450 on the multiple installation mechanisms 400, the push plates 450 abut against the pressure plates 442 and the plate body 410, moving synchronously towards the rock wall. When the plate body 410 moves, the support arm 430 pulls two adjacent guide plates 431 to move towards each other. Due to the limiting effect of the guide rail 440, the clamping cylinder 441, and the column 460, the plate body 410 always moves along the path of the guide rail 440 and is not easily tilted. Due to the different rock walls... The height of the rock face is uneven. As multiple push plates 450 move synchronously, the positioning screw 531 on the mounting mechanism 400 where the rock face is located contacts the pre-embedded screw sleeve in the adjacent pre-installation location. Then, as the push plates 450 continue to move, they compress the adjacent return spring 452, causing the plates 410 on other mounting mechanisms 400 to continue moving until the positioning screw 531 on the mounting mechanism 400 where the rock face is located contacts the pre-embedded screw sleeve in the adjacent pre-installation location. Then, multiple drive motors are activated, causing the drive motors to... The magnetic cylinder 421 is rotated, which in turn drives the positioning screw 531 to rotate via the convex strip. The positioning screw 531 is then screwed into the pre-embedded screw sleeve, thereby installing multiple support mechanisms 500 onto the rock wall. When the support mechanism 500 is installed onto the rock wall, the long arm of the L-shaped plate 510 and the seismic detector 520 remain parallel to the horizontal plane. When multiple push plates 450 are reset, the tension spring 432 will pull the adjacent plate 410 to reset, so that the plate 410 and the adjacent support arm 430 are arranged parallel to each other.

[0027] like Figure 1 As shown, in this embodiment, multiple connecting frames 110 are fixedly connected to the top surface of the mobile platform 100, and multiple placement frames 120 are fixedly connected to one side of each of the multiple connecting frames 110. Each placement frame 120 is equipped with a hydraulic cylinder. One connecting frame 110 is equipped with a fixing plate 401. The movable ends of multiple hydraulic cylinders on one connecting frame 110 are fixedly connected to the fixing plate 401, and the push plates 450 on multiple mounting mechanisms 400 are fixedly connected to the fixing plate 401. The movable ends of the hydraulic cylinders on the other connecting frames 110 are fixedly connected to the mobile frame 310.

[0028] In specific implementation, multiple hydraulic cylinders on one connecting frame 110 are equipped with a synchronous control system, and multiple hydraulic cylinders on other connecting frames 110 are also equipped with a synchronous control system. The hydraulic cylinders and their associated synchronous control systems are existing technologies and will not be described in detail here. Multiple hydraulic cylinders on one connecting frame 110 can drive multiple push plates 450 to move synchronously through the fixed plate 401, while the hydraulic cylinders on other connecting frames 110 can drive the moving frame 310 to move. Example 2

[0029] Based on Embodiment 1, a slide rail 130 is provided to facilitate the movement of the movable frame 310.

[0030] like Figures 1-2 As shown, in this embodiment, the top surface of the mobile platform 100 is fixedly connected to multiple slide rails 130, and each slide rail 130 has a slider that is slidably engaged inside it. The sliders are all fixedly connected to the bottom surface of the mobile frame 310.

[0031] In practice, the sliding frame 310 is limited by the slide rail 130 and the slider, and the weight of the sliding frame 310 is supported, so that the sliding frame 310 is more stable when it moves along the slide rail 130.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
