Abstract
Description
Technical Field
[0001] This invention relates to the field of mine anchoring technology, specifically to a combined pipe-slot anchor and its application method. Background Technology
[0002] Anchoring technology is an engineering technique that applies prestress by installing anchor bolts or anchor cables to improve the resistance of rock and soil to sliding and shearing. To prevent roof collapse and sidewall spalling accidents in strong mine roadways, anchor bolts are also needed at the mine roof. Slotted pipe anchors are a new type of anchor bolt that provides full-length anchoring and active reinforcement of the surrounding rock. Its three-dimensional part is a longitudinally slotted high-strength steel pipe. When installed in a borehole slightly smaller than its diameter, it immediately applies radial pressure and frictional force to the borehole wall along its entire length, preventing the surrounding rock from sliding down. Combined with the supporting force of the anchor bolt tray, this places the surrounding rock in a triaxial stress state, achieving rock strata stability.
[0003] Traditional slotted pipe anchors are typically used by directly inserting the pipe body into the top of the mine shaft to reinforce it. In this case, each slotted pipe anchor is independent of the others, which can lead to individual anchors falling off during the reinforcement process. Furthermore, workers cannot detect loosening of the anchors in time. Therefore, a combined slotted pipe anchor and its application method are proposed to address these issues. Summary of the Invention

[0008] Preferably, the first connecting plate is provided with insert plates on both the upper and lower sides, the second connecting plate is provided with insert plates on both the upper and lower sides, the end of the first connecting plate with the pin is arc-shaped, and the arc-shaped end of the first connecting plate is located inside the connecting frame.
[0009] Preferably, the detection body further includes a chassis, screws, sealing rings, and sliders. A slider is fixedly connected to the top left side of the fixed housing. The slider is set in the groove opened in the tube body. A chassis is set at the bottom of the battery. A screw threadedly connected to the fixed housing is provided through the chassis. A sealing ring is fixedly connected to the top of the chassis. There are two sealing rings in total, and both sealing rings are set at the bottom outer side of the battery. The top of the sealing rings is tightly fitted to the fixed housing.
[0010] Preferably, the pushing body further includes a push plate, a push shell, a sliding plate, a sliding rod, and a return spring. One end of the push plate is disposed inside the fixed shell, and the push shell is fixedly connected to the other end of the push plate outside the fixed shell. The push shell is slidably connected to the fixed shell. The end of the push plate away from the push shell is fixedly connected to the vertical rod. A connector is provided on the upper side of the push plate. Two sliding plates are fixedly connected to the bottom left side of the push plate in a front-to-back arrangement. A sliding rod is horizontally arranged and fixedly connected to the fixed shell through the sliding plate. A return spring is provided on the outer side of one end of the sliding rod.
[0011] Preferably, the pushing body further includes a positioning block, one side of which is fixedly connected to the vertical rod. The positioning block is positioned directly above the connector.

[0012] Preferably, the pressure sensing device includes a fixed block, a pressure sensing body, a rubber pad, and a spring. The fixed block is fixedly connected to the vertical rod. The pressure sensing body is installed inside the upper part of the fixed block. A rubber pad is installed on the top of the pressure sensing body. A spring is installed on the right side of the fixed block. A protrusion is provided at the bottom of the upper end of the spring. The horizontal plane at the top of the spring is located above the horizontal plane at the top of the second tray.
[0013] Preferably, a method for using a combined pipe joint anchor bolt includes the following steps: Step 1: Insert the pipe through the first and second pallets, and then use an impact device in conjunction with a hydraulic device to insert the pipe through the protective net into the mine. At this time, rotate the first and second pallets to adjust their angles. After adjustment, continue to insert the pipe into the mine. At this time, the pipe pushes the first pallet through the fixing ring, and the first pallet pushes the second pallet to fit against the inner wall of the mine. Step Two: The pusher plate is pushed by the push shell to slide within the fixed shell. The fixed shell pushes the slide plate to slide outside the slide rod. Simultaneously, the slide plate compresses the return spring and pushes the vertical rod to move. The vertical rod drives the connector to leave the connecting slot in the fixed shell. At this point, the vertical rod drives the positioning block and pressure sensing device into the tube body. Then, the vertical rod is inserted into the tube body. As the vertical rod moves upward, the tube body is inserted into the fixed shell. At this time, the slider slides into the tube slot in the tube body, thereby limiting the fixed block. When the bottom of the tube body enters and contacts the fixed shell... Slowly release the push shell. At this time, the return spring pushes the push plate to move. The push plate drives the pressure sensing device, positioning block and connector to move through the vertical rod. At this time, the connector is inserted into the connecting groove opened in the fixed shell, the positioning block is inserted into the positioning groove opened in the fixed shell through the insertion hole opened in the tube body, and the pressure sensing device is inserted into the slot opened in the tube body. The top of the spring of the pressure sensing device contacts the inner wall of the mine. The spring is deformed under the action of the inner wall of the mine. The protrusion of the spring squeezes the rubber pad. The rubber pad will deform and transmit the force to the pressure sensing body. Step 3: Place the battery on the chassis, then insert the battery into the fixed housing through the chassis. Install the chassis on the bottom of the fixed housing with screws. At this time, the battery sends current to the pressure sensing body through the fixed housing, connecting groove, connector, vertical rod and fixing block. The pressure sensing body senses the pressure and then sends the pressure signal to the server. When the pipe joint anchor is loose, the spring protrusion stops squeezing the rubber pad. At this time, the pressure sensing body does not sense the pressure. The staff can know the corresponding pipe joint anchor is loose in the server so that the pipe joint anchor can be maintained in time. Step 4: Rotate the first connecting plate. The first connecting plate will rotate outside the pin to adjust its angle. Then, clamp the two clip frames at the ends of the first connecting plate away from the pin. Insert the insert plate, which is fixedly connected to the two clip frames, into the limiting groove opened in the opposite clip frame. Then, thread the bolt through the insert plate and the nut fixedly connected to the top of the insert plate above to install the clip frame at the end of the first connecting plate away from the pin. Insert the second connecting plate into the end of the clip frame away from the first connecting plate. Then, install the second connecting plate at one end of the clip frame in the same way as above. At this time, continue to install the clip frame at the other end of the second connecting plate. Install the first connecting plate on the clip frame. This allows multiple first and second trays to be assembled, thereby connecting several pipe seam anchors together.
[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the pipe body, pipe groove, fixing ring, slot, support body and detection body are designed to allow the pipe body to be directly inserted into the mine. At this time, the fixing ring on the outside of the pipe body and the top of the support body fit together, so that the top of the support body fits against the inner wall of the mine, thereby anchoring the mine. Connecting multiple support bodies can make the mine anchoring more stable. At the same time, the detection body can detect the anchoring status, which makes it convenient for workers to eliminate safety hazards as soon as possible. 2. In this invention, by setting a first tray, a second tray, a support ring, a mounting plate, a clamping plate, a connecting frame, a pin, a first connecting plate, a second connecting plate, a fixing hole, a clamping frame, a limiting groove, a insert plate, a nut, a bolt, and a clamping groove, the first tray and the second tray can support the pipe when the inner wall of the mine falls off. At this time, the first tray and the second tray transmit pressure to the fixing ring, and the fixing ring transmits pressure to the pipe body. The friction between the outer wall of the pipe body and the mine prevents the pipe body from moving downward, thereby preventing the first tray and the second tray from moving downward and anchoring the mine. Then, the clamping frame is installed on the outside of the first connecting plate and the second connecting plate, and the bolt is threaded through the insert plate and connected to the nut. The insert plate and the clamping frame are installed on the outside of the first connecting plate and the second connecting plate. In this way, multiple first trays and second trays can be assembled. When one pipe body is loose, the other pipe bodies can prevent the loose pipe body from falling off, making the mine anchoring more stable. The first connecting plate can rotate outside the pin to adjust the angle of the first connecting plate, which facilitates the installation of pipe bodies at different positions in the mine. 3. In this invention, the tube body, slot, fixed shell, chassis, screw, sealing ring, battery, push plate, push shell, vertical rod, sliding plate, positioning block, fixing block, pressure sensing body, rubber pad, spring, slide rod, return spring, connector, slider, positioning groove, connecting groove, and insertion hole can push the push shell and push plate, thereby driving the vertical rod and sliding plate to move. At this time, the vertical rod moves inside the tube body, and the sliding plate compresses the return spring. Then, the fixed shell is fitted onto the outside of the tube body. After the push shell is released, the return spring pushes the push plate to return to its original position. The push plate drives the connector, positioning block, and fixing block to move through the vertical rod. At this time, the connector is inserted into the connecting groove opened in the fixed shell, and the battery connects to the pressure sensing body through the wire. The power supply and positioning block are inserted through the insertion hole in the tube body into the positioning groove in the fixed shell, thereby limiting the fixed shell and preventing it from falling off the outside of the tube body. The fixing block passes through the slot in the tube body, and the fixing block drives the spring to move. The top of the spring is in contact with the inner wall of the mine top. At this time, the spring is deformed by force, thereby pushing the rubber pad. The rubber pad squeezes the pressure sensing body, which can transmit pressure data to the server, so that the staff can know the loosening of the tube body as soon as possible and help the staff eliminate safety hazards. The battery is installed in the fixed shell. At this time, the screw can fix the chassis. The sealing ring can prevent moisture from entering the fixed shell, making the battery use more stable.

[0017] Please see Figure 1-16 The present invention provides a technical solution: A combined pipe-slot anchor bolt includes a pipe body 1, a support body 5, and a detection body 6. A pipe groove 2 is formed on the left side of the pipe body 1. A fixing ring 3 is fixedly connected to the bottom of the outer side of the pipe body 1. The detection body 6 is installed at the bottom end of the pipe body 1. The support body 5 is located on the outer side of the pipe body 1, with its bottom contacting the fixing ring 3. This design allows the pipe body 1 to be directly inserted into the mine shaft. At this point, the fixing ring 3 on the outer side of the pipe body 1 and its top are in contact with the support body 5, causing the top of the support body 5 to fit against the inner wall of the mine shaft, thus anchoring the mine shaft. Connecting multiple support bodies 5 can further stabilize the mine shaft anchorage. Simultaneously, the detection body 6 can detect the anchoring status, allowing workers to quickly eliminate potential safety hazards.
[0018] like Figure 1-7As shown, the supporting body 5 includes a first tray 51 and a second tray 52. The second tray 52 is fixedly connected to the top of the first tray 51. The tube 1 passes through the first tray 51 and the second tray 52. The bottom of the first tray 51 is convex downwards, and the convexity at the bottom of the first tray 51 fits tightly with the fixing ring 3. The supporting body 5 also includes a support ring 53, a mounting plate 54, a clamping plate 55, a connecting frame 56, a pin 57, and a connecting body 58. The support ring 53 is fixedly connected to the bottom of the first tray 51. The first tray 51 has convex-shaped slots 59 on all four sides. The clamping plate 55 is installed in the slots 59 of the first tray 51. The mounting plate 54 is fixedly connected to one side of the clamping plate 55. The end of the mounting plate 54 away from the clamping plate 55 is fixed. A connecting frame 56 is connected, and a vertically arranged pin 57 is installed through the connecting frame 56. A connecting body 58 is installed on the outside of the pin 57. The connecting body 58 includes a first connecting plate 581, a second connecting plate 582, a retaining frame 584, a limiting groove 585, a insert plate 586, a nut 587, and a bolt 588. One end of the first connecting plate 581 is located outside the pin 57. The end of the first connecting plate 581 away from the pin 57 has multiple fixing holes 583 equidistantly arranged along the length of the first connecting plate 581. The end of the first connecting plate 581 away from the pin 57 has a second connecting plate 582. Both ends of the second connecting plate 582 have multiple fixing holes 583 equidistantly arranged along the length of the first connecting plate 581. Two symmetrically arranged retaining frames 584 are provided on the outer sides of the connecting plate 581 and the second connecting plate 582, which are close to each other. An insert plate 586 is fixedly connected to one side of each retaining frame 584, and a limiting groove 585 corresponding to the insert plate 586 is provided on the other side of each retaining frame 584. An insert plate 586 is placed within the limiting groove 585 of the retaining frame 584. A nut 587 is fixedly connected to the top of the upper insert plate 586, and a bolt 588 penetrating the insert plate 586 is threaded into the nut 587. Bolts 588 are installed in one of the fixing holes 583 of both the first connecting plate 581 and the second connecting plate 582. Inserting plates 586 are provided on both the upper and lower sides of the first connecting plate 581, and inserting plates 586 are provided on both the upper and lower sides of the second connecting plate 582. The system includes an insert plate 586 and a first connecting plate 581 with an arc-shaped end containing a pin 57. This arc-shaped end of the first connecting plate 581 is positioned within the connecting frame 56. This design allows for support by the first tray 51 and the second tray 52 when the inner wall of the mine shaft detaches. The first tray 51 and the second tray 52 then transmit pressure to the fixing ring 3, which in turn transmits pressure to the pipe body 1. The friction between the outer wall of the pipe body 1 and the mine shaft prevents the pipe body 1 from moving downwards, thus preventing the first tray 51 and the second tray 52 from moving downwards and anchoring the mine shaft. Afterwards, a clip frame 584 is installed on the outside of the first connecting plate 581 and the second connecting plate 582, and a bolt 588 is threaded through the insert plate 586 and connected to a nut 587.The insert plate 586 and the clip frame 584 are installed on the outside of the first connecting plate 581 and the second connecting plate 582, thereby allowing the assembly of multiple first trays 51 and second trays 52. If one pipe 1 becomes loose, the other pipes 1 can prevent it from falling off, making the mine anchoring more stable. The first connecting plate 581 can rotate outside the pin 57, thereby adjusting the angle of the first connecting plate 581, facilitating the installation of pipes 1 at different locations within the mine.
[0019] like Figure 8-16As shown, the detection body 6 includes a fixed shell 61, a chassis 62, screws 63, a battery 65, and a pushing body 66. The battery 65 is located inside the bottom of the fixed shell 61, and the chassis 62 is located at the bottom of the battery 65. A screw 63, threadedly connected to the fixed shell 61, passes through the chassis 62. The pushing body 66 is located on one side of the fixed shell 61. The detection body 6 also includes sealing rings 64. Two sealing rings 64 are fixedly connected to the top of the chassis 62, and both sealing rings 64 are located on the outer bottom of the battery 65. The top of the sealing rings 64 are tightly fitted to the fixed shell 61. The detection body 6 also includes a slider 67. A slider 67 is fixedly connected to the left side of the top of the fixed shell 61. The slider 67 is located within the groove 2 opened in the tube body 1. The pushing body... The pusher body 66 includes a vertical rod 663, a pressure sensing device 666, and a connector 669. The connector 669 is fixedly connected to the bottom right side of the vertical rod 663. A connecting groove 69 is opened on one side of the fixed housing 61, and the connector 669 is installed in the connecting groove 69 opened in the fixed housing 61. The pressure sensing device 666 is installed at the top right side of the vertical rod 663. A slot 4 is opened on the right side of the tube body 1. The pressure sensing device 666 is located inside the second tray 52. The pusher body 66 also includes a push plate 661, a push shell 662, a slide plate 664, a slide rod 667, and a return spring 668. One end of the push plate 661 is located inside the fixed housing 61, and the other end of the push plate 661 located outside the fixed housing 61 is fixedly connected to the push shell 662. The push shell 662 is slidably connected to the fixed housing 61. The end of the push plate 661 away from the push shell 662 is fixedly connected to the vertical rod 663. A connector 669 is provided on the upper side of the push plate 661. Two sliding plates 664 arranged front and back are fixedly connected to the bottom left side of the push plate 661. A horizontally arranged sliding rod 667 is fixedly connected to the fixed shell 61 through the sliding plate 664. A return spring 668 is provided on the outer side of one end of the sliding rod 667. The push body 66 also includes a positioning block 665. One side of the positioning block 665 is fixedly connected to the vertical rod 663. The positioning block 665 is located directly above the connector 669. An insertion hole 7 is opened at the bottom right side of the tube body 1. The positioning block 665 passes through the insertion hole 7 opened in the tube body 1. A positioning groove 68 is opened on the right side of the fixed shell 61. The end of the positioning block 665 away from the vertical rod 663 is located at the groove 68 opened in the fixed shell 61. Within the positioning slot 68, the pressure sensing device 666 includes a fixing block 6661, a pressure sensing body 6662, a rubber pad 6663, and a spring 6664. The fixing block 6661 is fixedly connected to the vertical rod 663. The pressure sensing body 6662 is installed on the upper part of the fixing block 6661, and the rubber pad 6663 is installed on the top of the pressure sensing body 6662. The spring 6664 is installed on the right side of the fixing block 6661. A protrusion is provided at the bottom of the upper end of the spring 6664, and the horizontal plane at the top of the spring 6664 is positioned above the horizontal plane at the top of the second tray 52. This configuration allows the pusher shell 662 and the push plate 661 to be pushed towards the fixing shell 61, thereby driving the vertical rod 663 and the sliding plate 664 to move. At this time, the vertical rod 663 moves inside the tube body 1.The sliding plate 664 compresses the return spring 668, then mounts the fixing shell 61 onto the outside of the tube body 1. After releasing the push shell 662, the return spring 668 pushes the push plate 661 to reset. The push plate 661, via the vertical rod 663, moves the connector 669, positioning block 665, and fixing block 6661. At this time, the connector 669 inserts into the connecting slot 69 of the fixing shell 61. The battery 65 supplies power to the pressure sensing body via wires. The positioning block 665 passes through the insertion hole 7 of the tube body 1 and inserts into the positioning slot 68 of the fixing shell 61, thus limiting the fixing shell 61 and preventing it from falling off the outside of the tube body 1. The fixing block 6661 passes through the slot 4 of the tube body 1. The fixed block 6661 drives the spring 6664 to move, and the top of the spring 6664 fits against the inner wall of the mine roof. At this time, the spring 6664 deforms under force, thereby pushing the rubber pad 6663. The rubber pad 6663 squeezes the pressure sensing body 6662, which can transmit pressure data to the server. When the pressure sensing body 6662 does not detect a pressure signal, the staff will know immediately that the tube 1 is loose, so that the staff can eliminate the safety hazard and install the battery 65 into the fixed shell 61. At this time, the screw 63 can fix the chassis 62. The sealing ring 64 can prevent moisture from entering the fixed shell 61, making the battery 65 more stable.
[0020] Instructions for use: This device is powered by battery 65 or an external power source. Insert the tube 1 through the first tray 51 and the second tray 52. Then, using an impact device in conjunction with a hydraulic device, insert the tube 1 through the protective netting into the mine shaft. Rotate the first tray 51 and the second tray 52 to adjust their angles. After adjustment, continue inserting the tube 1 into the mine shaft. The tube 1 pushes the first tray 51 through the fixing ring 3, and the first tray 51 pushes the second tray 52 to fit against the inner wall of the mine shaft. Place the battery 65 on the base 62, and then insert the battery 65 into the fixed housing 61 through the base 62. Secure the base 62 to the bottom of the fixed housing 61 using screws 63. The battery 65 then passes through the fixed housing 61 and the connecting groove 69. The connector 669, vertical rod 663, and fixing block 6661 send current to the pressure sensing body 6662. The pressure sensing body 6662 senses the pressure and then sends the pressure signal to the server. When the pipe joint anchor rod loosens, the protrusion of the spring 6664 stops squeezing the rubber pad 6663. At this time, the pressure sensing body 6662 does not sense the pressure. The staff can know in the server that the corresponding pipe joint anchor rod is loose so as to maintain the pipe joint anchor rod in time. Rotate the first connecting plate 581. At this time, the first connecting plate 581 rotates outside the pin 57 to adjust the angle of the first connecting plate 581. Then, the two clips 584 are respectively locked at the ends of the first connecting plate 581 away from the pin 57. Two retaining frames 584 are fixedly connected by insert plates 586, which are inserted into the limiting grooves 585 opened in the opposite retaining frame 584. Then, bolts 588 are threaded through the bottom of the insert plates 586 and the first connecting plate 581 and are threaded into the nuts 587 fixedly connected to the top of the upper insert plate 586. This installs the retaining frame 584 at the end of the first connecting plate 581 away from the pin 57. A second connecting plate 582 is then inserted at the end of the retaining frame 584 away from the first connecting plate 581. The second connecting plate 582 is then installed at one end of the retaining frame 584 in the same manner.
