Description

Technical Field

[0001] This invention relates to the field of tunnel construction equipment technology, specifically to a tunnel pipe roof construction guidance and correction device. Background Technology

[0002] Advanced pipe roof support technology, as an important pre-support method, can effectively control the deformation of surrounding rock during tunnel excavation, ensuring construction safety and project quality. It has been widely used in various tunnel construction projects, including railway tunnels, highway tunnels, and urban rail transit tunnels. The tunnel cross-section pipe roof drilling device, as the core equipment for realizing advanced pipe roof support, directly determines the support effect of the pipe roof through its drilling accuracy, and has a crucial impact on the overall construction progress and structural stability of the tunnel.

[0003] Currently, the existing tunnel cross-section pipe roof drilling devices on the market are subject to a combination of factors during construction, and the actual drilling angle of the drill bit is very likely to deviate from the preset angle. If the drilling angle deviation cannot be corrected in a timely and effective manner, the angle deviation will continue to accumulate as the drilling depth increases, eventually causing the actual laying position of the advanced pipe roof to deviate seriously from the design axis.

[0004] Meanwhile, due to the depth requirements of the pipe roof design, longer drill rods are required during construction. As a slender rod, the drill rod is prone to sagging in the middle under gravity, causing the entire drill rod to bend elastically. This bending deformation directly changes the stress state and drilling trajectory of the drill rod, making it impossible for the front drill bit to drill strictly along the preset axis, thus causing deviation in the drilling angle.

[0005] Therefore, the present invention provides a tunnel pipe roof construction guidance and correction device to solve the above problems. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, the present invention provides a tunnel pipe roof construction guidance and correction device, which effectively solves the problem that the actual drilling angle of the drill bit is very easy to deviate from the preset angle. If the drilling angle deviation cannot be corrected in a timely and effective manner, the angle deviation will continue to accumulate as the drilling depth increases, eventually causing the actual laying position of the advanced pipe roof to deviate seriously from the design axis.

[0010] Preferably, the end of the correction support plate away from the angle adjustment push block is fixedly connected to a reset extension plate that cooperates with the correction control ring.

[0011] Preferably, the sleeve connection structure includes a sleeve connection bushing, which is fixedly connected between the two control support sleeves. The sleeve connection bushing has a plurality of support grooves distributed along the circumferential direction of the control support sleeve.

The sleeve connecting bushing is provided with an unlocking structure for controlling the self-locking slider to move away from the self-locking groove.

[0012] Preferably, the unlocking structure includes a sliding groove formed inside the support groove. Multiple inclined guide grooves are formed on both sides of the sliding groove, and these guide grooves are arranged parallel to each other. An unlocking slider is slidably connected inside the sliding groove. Multiple guide shafts, each slidably connected to the guide grooves, are fixedly connected to both sides of the unlocking slider. A control plate that cooperates with the unlocking slider is slidably connected up and down inside the control slider. A return spring is provided between the control plate and the control slider. A trapezoidal unlocking plate is fixedly connected to the end of the unlocking slider away from the self-locking groove. Pulling blocks that cooperate with the unlocking plate are fixedly connected to both ends of the control plate. A drill rod connecting sleeve is slidably connected inside the sleeve connecting sleeve. The drill rod connecting sleeve is used to connect the drill rod.

[0017] The beneficial effects of this invention are as follows: This invention addresses the problem that the actual drilling angle of the drill bit is easily deviated from the preset angle. If the drilling angle deviation cannot be corrected in a timely and effective manner, the angle deviation will continue to accumulate as the drilling depth increases, eventually leading to a serious deviation of the actual laying position of the advanced pipe roof from the design axis. By adding a sleeve connecting bushing, support groove, support plate, control slider, connecting rod, self-locking slider and spring, the problem of the drill rod being a slender structure and prone to unavoidable sagging in the middle of the rod under the action of gravity is solved. This causes the drill rod to bend elastically as a whole. This bending deformation will directly change the stress state and drilling trajectory of the drill rod, making it impossible for the front drill bit to drill strictly along the preset axis, thus causing the drilling angle deviation problem. This invention can effectively monitor and adjust drill pipe offset in real time, and quickly adjust its angle. Attached Figure Description

[0025] Furthermore, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0026] Example 1, refer to the appendix of the instruction manual. Figure 1-15 A tunnel pipe roof construction guidance and correction device includes a track frame 1, a drilling sliding frame 2 slidably connected to the track frame 1, a threaded rod rotatably connected to the track frame 1, the threaded rod and the drilling sliding frame 2 being threadedly connected, multiple drill rods 3 connected end to end on the drilling sliding frame 2, and a drilling drive device for controlling the rotation of the drill rods 3 on the drilling sliding frame 2. The drilling drive device is driven by a motor, and in use, the drill rods 3 are rotated by the motor. A drill bit 4 is provided at the end of the drill rod 3 away from the drilling sliding frame 2. A control support sleeve 5 is sleeved on the outside of the drill rod 3. The control support sleeves 5 are connected to each other by a sleeve connection structure. The control support sleeves 5 and the drill bit 4 are connected by a correction connecting bushing 6. The control support sleeves 5 and the correction connecting bushing 6 are fixedly connected by bolts. The correction connecting bushing 6 and the drill bit 4 are slidably connected. In use, when the control support sleeves 5 are pulled to move closer to or away from the drill bit 4, the correction connecting bushing 6 moves synchronously to move closer to or away from the drill bit 4.

[0027] One end of the correction support plate 7 is rotatably connected to the correction connecting bushing 6, and the other end of the correction support plate 7 is fixedly provided with an angle adjustment push block 8. The angle adjustment push block 8 is set as a right trapezoid and is located on the side of the correction support plate 7 close to the drill rod 3. The drill pipe 3 is equipped with a wired guide instrument to detect the levelness; during use, the drilling angle of the drill pipe 3 is monitored in real time through the wired guide instrument.

[0028] Inside the correction connecting bushing 6, there is a drill connecting bushing 9 that is slidably connected. On the drill connecting bushing 9, there is a correction control ring 10 that cooperates with the angle adjustment push block 8. Both sides of the correction control ring 10 are provided with chamfers.

[0029] In use, when the wired guide detects that the drill bit 4 has deviated, the control support sleeve 5 is rotated so that the correction support plate 7 is in the direction of the drill bit 4's deviation. Then, the control support sleeve 5 is pushed to move closer to the drill bit 4, and the correction connecting sleeve 6 moves synchronously closer to the drill bit 4. At this time, the inclined surfaces of the correction control ring 10 and the angle adjustment push block 8 come into contact. Then, the correction control ring 10 pushes the angle adjustment push block 8 to move away from the drill rod 3, thereby pushing the drill bit 4 back to the predetermined position. For example, when the drill bit 4 deviates upward, the control support sleeve 5 is rotated so that the correction support plate 7 is above the correction connecting sleeve 6. The correction control ring 10 pushes the angle adjustment push block 8 to move away from the drill rod 3, thereby pushing the drill bit 4 downward and returning the drill bit 4 to the predetermined position.

[0030] The drilling sliding frame 2 is provided with a correction control structure for driving the control support sleeve 5 to rotate and slide; the correction control structure includes a control slide 11 slidably connected to the drilling sliding frame 2, the control slide 11 and the control support sleeve 5 are rotatably connected, a correction rotation gear 12 is fixedly connected to one end of the control support sleeve 5 near the drilling sliding frame 2, a rotation motor 13 is fixedly connected to the control slide 11, and a correction drive gear 14 that meshes with the correction rotation gear 12 is fixedly connected to the shaft end of the rotation motor 13; When the drill bit 4 deviates during use, the rotating motor 13 drives the correction drive gear 14 to rotate, which in turn drives the correction rotating gear 12 to rotate. The correction rotating gear 12 then drives the control support sleeve 5 to rotate, which in turn drives the correction connecting shaft sleeve 6 to rotate. During installation, a mark is set on the correction rotating gear 12 so that the mark on the correction rotating gear 12 corresponds to the correction support plate 7, thereby facilitating the control of the position of the correction support plate 7.

[0031] A sliding control hydraulic cylinder 15 is installed on the drilling sliding frame 2, and the extended shaft end of the sliding control hydraulic cylinder 15 is fixedly connected to the control sliding frame 11.

[0032] In use, the sliding control hydraulic cylinder 15 pulls the control slide 11 to move closer to or further away from the drill bit 4.

[0033] The end of the correction support plate 7 away from the angle adjustment push block 8 is fixedly connected to a reset extension plate 16 that cooperates with the correction control ring 10.

[0034] When the drill bit 4 returns to the predetermined position, the sliding control hydraulic cylinder 15 controls the support sleeve 5 to pull the correction connecting sleeve 6 away from the drill bit 4. The correction connecting sleeve 6 simultaneously drives the correction support plate 7 to move, so that the correction control ring 10 and the reset extension plate 16 come into contact. Thus, the reset extension plate 16 pushes the correction support plate 7 into the correction connecting sleeve 6, which facilitates the control of the drill bit 4 and drill rod 3 to be pulled out from the borehole.

[0035] In embodiment two, the sleeve connection structure includes a sleeve connection bushing 17, which is fixedly connected between two control support sleeves 5. The sleeve connection bushing 17 has multiple support grooves 18 distributed along the circumference of the control support sleeves 5. One end of a support plate 19 is rotatably connected inside each support groove 18. A control slider 20 is slidably connected inside the support groove 18. A connecting rod 21 connects the control slider 20 and the support plate 19. A reinforcing support block 38 is provided at the swing end of the support plate 19 to reinforce the support plate 19.

[0036] The support groove 18 has self-locking grooves 22 on both sides. The control slider 20 has a self-locking slider 23 slidably connected inside. One end of the self-locking slider 23 is fixedly connected to a locking tooth 24 that cooperates with the self-locking groove 22. The cross sections of the self-locking groove 22 and the locking tooth 24 are set as right triangles. A spring is provided between the self-locking slider 23 and the control slider 20. In the initial state, the spring pushes the self-locking slider 23 toward the self-locking groove 22, thereby pushing the locking tooth 24 into the self-locking groove 22; When in use, push the control slider 20 away from the drill bit 4. At this time, the connecting rod 21 drives the support plate 19 to open, so that the open end of the support plate 19 supports the inner wall of the borehole, thereby supporting the sleeve connecting bushing 17. This is to prevent the drill rod 3 from bending and deforming due to its long length. When the control slider 20 slides away from the drill bit 4, the inclined edge of the locking tooth 24 contacts the inclined edge of the self-locking groove 22. After being guided by the inclined edge of the self-locking groove 22, the locking tooth 24 is pushed away from the self-locking groove 22. When the control slider 20 is pushed to the appropriate position, the connecting rod 21 drives the support plate 19 to the limit position, so that the opened end of the support plate 19 contacts the inner wall of the borehole. At this time, the straight edge of the self-locking groove 22 and the straight edge of the locking tooth 24 are in contact, so that the self-locking groove 22 restricts the locking tooth 24 to the current position and prevents the control slider 20 from sliding closer to the drill bit 4.

[0037] The sleeve connecting bushing 17 is provided with an unlocking structure for controlling the self-locking slider 23 to move away from the self-locking groove 22; the unlocking structure includes a sliding groove 25 opened inside the support groove 18, and multiple inclined guide grooves 26 are opened on both sides of the sliding groove 25. The multiple guide grooves 26 are arranged in parallel. An unlocking slider 27 is slidably connected inside the sliding groove 25. Multiple guide shafts 28 that are slidably connected to the guide grooves 26 are fixedly connected on both sides of the unlocking slider 27. In use, the unlocking slider 27 is pushed to slide inside the sliding groove 25, and the unlocking slider 27 is controlled to slide closer to or further away from the control slider 20 by sliding inside the guide groove 26 via the guide shaft 28.

[0038] The control slider 20 is internally connected to a control plate 29 that cooperates with the unlocking slider 27. A reset spring is provided between the control plate 29 and the control slider 20. The end of the unlocking slider 27 away from the self-locking groove 22 is fixedly connected to a trapezoidal unlocking plate 30. Both ends of the control plate 29 are fixedly connected to a pull block 31 that cooperates with the unlocking plate 30. A drill rod connecting sleeve 32 is slidably connected inside the sleeve connecting sleeve 17. The drill rod connecting sleeve 32 is used to connect the drill rod 3. An unlocking control ring 33 is fixedly connected to the drill rod connecting sleeve 32. The lower end of the unlocking slider 27 is fixedly connected to a drive board 34 that cooperates with the unlocking control ring 33.

[0039] In the initial state, the control plate 29 is pushed away from the control slider 20 by the action of the reset spring; In use, push the control support sleeve 5 away from the drill bit 4, which simultaneously moves the casing connecting sleeve 17. The unlocking control ring 33 and the drive plate 34 come into contact. When the casing connecting sleeve 17 moves, the unlocking control ring 33 restricts the drive plate 34. The unlocking slider 27 moves upward under the action of the guide groove 26. The unlocking slider 27 pushes the control plate 29 upward. At this time, the pull blocks 31 on both sides of the control plate 29 come into contact with the unlocking plate 30. The inclined edge of the pull block 31 and the inclined edge of the unlocking plate 30 are in contact. When the control plate 29 slides upward to the limit position, the pull block 31 pulls the unlocking plate 30 to move closer to the unlocking slider 27. At this time, the self-locking slider 23 drives the locking tooth 24 to move away from the self-locking groove 22, so that the locking tooth 24 and the self-locking groove 22 are separated. At this time, the control slider 20 can move freely, and the support plate 19 can return to the initial position.

[0040] A support adjustment slider 35 is slidably connected to the upper end of the control slider 20, and a compression spring is installed between the support adjustment slider 35 and the control slider 20. In the initial state, under the action of the compression spring, the support adjustment slider 35 is pushed to move to the extreme position in a direction away from the control slider 20.

[0041] A support control frame 36 is fixedly connected to one end of the track frame 1 near the drill bit 4. A control ring 37 that cooperates with the support adjustment slider 35 is provided on the support control frame 36. The end of the support adjustment slider 35 away from the control slider 20 is set as a hemisphere to facilitate its cooperation with the control ring 37.

[0042] During use, the drilling sliding frame 2 is pushed to perform drilling operations. Simultaneously, the drilling sliding frame 2 drives the control support sleeve 5 to move, causing the sleeve connecting bushing 17 to pass through the control ring 37. The end of the support adjusting slider 35 away from the control slider 20 contacts the inner wall of the control ring 37. Then, the control support sleeve 5 is pushed further. Under the action of the compression spring, the support adjusting slider 35 drives the control slider 20 to slide away from the drill bit 4. Through the control slider 20 and the connecting rod 21, the support plate 19 is opened until the opened end of the support plate 19 contacts the inner wall of the borehole. At this point, the support plate 19 can no longer be opened, and the control slider 20 can no longer slide. At this time, the control support sleeve 5 is pushed further, and the control ring 37 presses the support adjusting slider 35 downward until the support adjusting slider 35 passes through the control ring 37. Under the action of the compression spring, the support adjusting slider 35 is pushed back to its original position.

[0043] A stabilizing plate 39 is fixedly connected to one end of the track frame 1 near the drill bit 4. A ball bearing 43 is provided on the reinforcing support block 38. During use, the stabilizing plate 39 fits against the tunnel end face to improve the stability of the track frame 1. The ball bearing 43 is used to reduce friction.

[0044] In embodiment 3, both ends of the drill rod connecting sleeve 32 are fixedly connected with sleeve connecting rings 40. The sleeve connecting rings 40 are provided with multiple locking grooves 41 distributed along the circumference of the sleeve connecting rings 40. Both ends of the drill rod 3 are fixedly connected with multiple locking blocks 42 that cooperate with the locking grooves 41.

[0045] In use, the bushing connecting rings 40 at both ends of the drill rod connecting bushing 32 are inserted into the beginning and end ends of two adjacent drill rods 3 respectively, and the snap-fit ​​block 42 is snapped into the snap-fit ​​groove 41. Then, the drill rod 3 is fixed on the drill rod connecting bushing 32 by fixing bolts, thereby connecting multiple drill rods 3 through the drill rod connecting bushing 32.

[0046] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
