Description

Technical Field

[0001] This invention belongs to the technical field of drilling and splitting equipment, specifically relating to an integrated drilling and splitting system capable of handling pressure chamber obstacles under pressure. Background Technology

[0002] Currently, there are two main methods for handling boulders during tunnel boring machine (TBM) excavation, both domestically and internationally: The first is blasting, where the amount of explosives used per borehole is calculated based on the size of the boulder, and then blasting is carried out through drilling. The second method involves using a drilling rig on the ground to drill through and remove the boulder, followed by backfilling. For larger boulders, an inclined shaft is excavated for removal. In some cases, hydraulic breakers or similar devices are installed around the cutterhead to break up the boulders. However, based on actual construction cases and relevant literature, both methods have significant limitations.

[0003] Blasting isolated boulders requires precise calculation of the explosive charge and can interfere with the surrounding rock and strata during the blasting process, leading to poor feasibility. While drilling rigs on the ground causes less interference with the surrounding rock and strata, the drilling rigs operate under pressure. However, leaks frequently occur at the connection between the tunnel boring machine (TBM) and the drilling rig during drilling, affecting the TBM's sealing performance and reducing the efficiency of boulder removal.

[0004] The problem to be solved by the present invention is to provide a drilling and splitting integrated system that can handle pressure chamber obstacles under pressure, in order to solve the problem that the drilling rig cannot drill and split the isolated rock under pressure when the tunnel boring machine encounters it during the tunneling process. Summary of the Invention

[0005] This invention provides an integrated drilling and splitting system capable of handling pressure chamber obstacles under pressure, thereby solving at least some of the aforementioned technical problems.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A drill-and-split integrated system for handling pressure chamber obstacles under pressure includes a frame mounted on the cutterhead of a tunnel boring machine (TBM), a sliding mechanism slidably mounted on the frame, a drill-and-split mechanism mounted on the sliding mechanism and capable of drilling and splitting boulders through the TBM cutterhead, and a sealing mechanism mounted on the frame and slidably connected to the drill-and-split mechanism for sealing the drill-and-split mechanism.

[0007] Furthermore, the sealing mechanism includes a cutter barrel mounted on the frame and connected to the cutterhead of the tunnel boring machine, a high-pressure ball valve located inside the cutter barrel, and a blowout prevention mechanism located inside the cutter barrel and connected to the high-pressure ball valve. The drilling and splitting mechanism is slidably installed inside the high-pressure ball valve and the blowout prevention mechanism and passes through the cutter barrel.

[0008] Furthermore, the blowout preventer includes a blowout preventer mounting housing disposed on the high-pressure ball valve, and a sealing sleeve disposed on the blowout preventer mounting housing and in contact with the drilling and splitting mechanism.

[0009] Furthermore, the sliding mechanism includes a sliding seat slidably mounted on the frame, a sliding mounting seat slidably mounted on the sliding seat and connected to the drilling and splitting mechanism, and a driving mechanism mounted on the sliding seat and connected to the sliding mounting seat for driving the sliding mounting seat to reciprocate.

[0010] Furthermore, a clearance groove is provided on the sliding seat, and the driving mechanism includes a reducer provided on the sliding seat, a hydraulic pump provided on the reducer and connected to the input end of the reducer, and a transmission mechanism rotatably provided in the sliding seat and connected to the output end of the reducer. The sliding seat passes through the clearance groove and is connected to the transmission mechanism.

[0011] Furthermore, the transmission mechanism includes a transmission shaft rotatably mounted on a sliding seat and connected to the output end of a reducer, a drive sprocket mounted on the transmission shaft, several mounting shafts mounted in the sliding seat, driven sprockets mounted on the mounting shafts, and a chain mounted between the drive sprocket and the driven sprocket. A connecting block is provided on the sliding mounting seat, and the connecting block passes through a clearance groove and connects to the chain.

[0012] Furthermore, the frame is provided with two sets of mirror-symmetrically arranged sliders A, and sliding plates A are provided on both sides of the sliding base, with the sliding plates A slidably installed inside the sliders A.

[0013] Furthermore, the frame is provided with a mounting base, the sliding base is provided with a connecting base, and a hydraulic cylinder is provided between the mounting base and the connecting base.

[0014] Furthermore, the top of both sides of the sliding seat is provided with a sliding plate B, and the bottom of the sliding mounting seat is provided with a slider B, which is slidably mounted on the sliding plate B.

[0015] Furthermore, the drilling and splitting mechanism includes an anchoring rotary device mounted on a sliding mechanism, a splitting rod mounted on the output end of the anchoring rotary device and slidably passing through a sealing mechanism, and a drill bit mounted at the end of the splitting rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention has a simple structure, a scientific and reasonable design, and is easy to use. The present invention can seal the drilling and splitting mechanism through the sealing mechanism, thereby enabling the drilling and splitting mechanism to operate under pressure, which facilitates the drilling and splitting mechanism to drill and split isolated rocks. At the same time, when the drilling and splitting mechanism is running, it can drill holes in isolated rocks first and then split them, thereby improving the processing effect of isolated rocks.

[0017] During the process, it can simultaneously drill holes and split boulders, thereby increasing the tunneling speed of the tunnel boring machine.

[0018] 2. The sliding mechanism of the present invention is slidably mounted on the frame, so that the hydraulic cylinder can drive the sliding mechanism to move on the frame, thereby realizing the first-level movement of the drilling and splitting mechanism. At the same time, the sliding mechanism can also drive the drilling and splitting mechanism to move again, so that the drilling and splitting mechanism can move a second time. In the above way, the drilling and splitting depth of the drilling and splitting mechanism can be increased, thereby facilitating the drilling and splitting mechanism to drill holes and split boulders.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] Example 1, such as Figure 1-7 As shown, the present invention provides a drilling and splitting integrated system for handling pressure chamber obstacles under pressure, including a frame 2 mounted on a shield machine cutterhead 1, a sliding mechanism slidably mounted on the frame 2, a drilling and splitting mechanism mounted on the sliding mechanism and capable of passing through the shield machine cutterhead 1 to drill and split boulders, and a sealing mechanism mounted on the frame 2 and slidably connected to the drilling and splitting mechanism for sealing the drilling and splitting mechanism.

[0031] This invention can seal the drilling and splitting mechanism through a sealing mechanism, thereby enabling the drilling and splitting mechanism to operate under pressure. This facilitates the drilling and splitting mechanism to drill and split boulders. At the same time, the drilling and splitting mechanism can drill holes and split boulders simultaneously during operation, thereby increasing the tunneling speed of the tunnel boring machine.

[0032] In this invention, a sliding mechanism is slidably mounted on the frame 2, so that the hydraulic cylinder 24 can drive the sliding mechanism to move on the frame 2, thereby realizing the first-stage movement of the drilling and splitting mechanism. At the same time, the sliding mechanism can also drive the drilling and splitting mechanism to move again, so that the drilling and splitting mechanism can move a second time. In this way, the drilling and splitting depth of the drilling and splitting mechanism can be increased, thereby facilitating the drilling and splitting mechanism to drill holes and split boulders.

[0033] Example 2, as Figure 1-7As shown, the present invention provides a drilling and splitting integrated system for handling pressure chamber obstacles under pressure, including a frame 2 mounted on a shield machine cutterhead 1, a sliding mechanism slidably mounted on the frame 2, a drilling and splitting mechanism mounted on the sliding mechanism and capable of passing through the shield machine cutterhead 1 to drill and split boulders, and a sealing mechanism mounted on the frame 2 and slidably connected to the drilling and splitting mechanism for sealing the drilling and splitting mechanism.

[0034] The sealing mechanism includes a cutter barrel 3 mounted on the frame 2 and connected to the cutterhead 1 of the tunnel boring machine, a high-pressure ball valve 4 located inside the cutter barrel 3, and a blowout prevention mechanism located inside the cutter barrel 3 and connected to the high-pressure ball valve 4. The drilling and splitting mechanism slides through the high-pressure ball valve 4 and the blowout prevention mechanism and passes through the cutter barrel 3.

[0035] This embodiment 2 provides a more detailed structure of the sealing mechanism based on embodiment 1. The sealing mechanism includes a cutter barrel 3 located on the frame 2 and connected to the cutterhead 1 of the tunnel boring machine, a high-pressure ball valve 4 located inside the cutter barrel 3, and a blowout prevention mechanism located inside the cutter barrel 3 and connected to the high-pressure ball valve 4. The drilling and splitting mechanism slides through the high-pressure ball valve 4 and the blowout prevention mechanism and passes through the cutter barrel 3.

[0036] The cutter barrel 3 of this invention is mounted on the frame 2 and connected to the cutter holder 1 of the tunnel boring machine. The high-pressure ball valve 4 is located inside the cutter barrel 3. During use, when the drilling and splitting mechanism is running, the high-pressure ball valve 4 is in the open state. At this time, the cutter barrel 3 is sealed by the blowout prevention mechanism. At the same time, when the drilling and splitting mechanism is located inside the cutter barrel 3, the high-pressure ball valve 4 can be closed, thereby further improving the sealing of the cutter barrel 3.

The blowout preventer includes a blowout preventer mounting housing 5 disposed on the high-pressure ball valve 4, and a sealing sleeve 6 disposed on the blowout preventer mounting housing 5 and in contact with the drilling and splitting mechanism.

[0041] When this invention is used, the sealing sleeve 6 contacts the outer wall of the splitting rod 28 to achieve a seal on the splitting rod 28 (this is a dynamic seal) to prevent the leakage of mud or groundwater in the boulder, which would affect the sealing performance of the tunnel boring machine, thereby enabling the drilling rig to operate under pressure.

[0048] The sliding mechanism includes a sliding seat 9 slidably mounted on the frame 2, a sliding mounting seat 10 slidably mounted on the sliding seat 9 and connected to the drilling and splitting mechanism, and a driving mechanism mounted on the sliding seat 9 and connected to the sliding mounting seat 10 for driving the sliding mounting seat 10 to reciprocate.

[0049] The sliding seat 9 has a clearance groove 11. The drive mechanism includes a reducer 12 on the sliding seat 9, a hydraulic pump 13 on the reducer 12 and connected to the input end of the reducer 12, and a transmission mechanism rotatably disposed in the sliding seat 9 and connected to the output end of the reducer 12. The sliding seat 9 passes through the clearance groove 11 and is connected to the transmission mechanism.

[0050] This embodiment 5 provides a more detailed structure of the drive mechanism based on embodiment 4. The sliding seat 9 is provided with a clearance groove 11. The drive mechanism includes a reducer 12 provided on the sliding seat 9, a hydraulic pump 13 provided on the reducer 12 and connected to the input end of the reducer 12, and a transmission mechanism rotatably provided in the sliding seat 9 and connected to the output end of the reducer 12. The sliding seat 9 passes through the clearance groove 11 and is connected to the transmission mechanism.

[0051] The hydraulic pump 13 of this invention is connected to the hydraulic station on the tunnel boring machine. When in use, the hydraulic pump 13 is started, the hydraulic pump 13 drives the reducer 12 to run, the reducer 12 drives the transmission mechanism to run, and the transmission mechanism drives the sliding seat 9 to move synchronously, thereby enabling the drilling and splitting mechanism to move synchronously, thereby adjusting the drilling depth of the drilling and splitting mechanism, which facilitates the drilling and splitting mechanism to drill holes and split boulders.

[0052] Example 6, as Figure 1-7 As shown, the present invention provides a drilling and splitting integrated system for handling pressure chamber obstacles under pressure, including a frame 2 mounted on a shield machine cutterhead 1, a sliding mechanism slidably mounted on the frame 2, a drilling and splitting mechanism mounted on the sliding mechanism and capable of passing through the shield machine cutterhead 1 to drill and split boulders, and a sealing mechanism mounted on the frame 2 and slidably connected to the drilling and splitting mechanism for sealing the drilling and splitting mechanism.

A connecting block 19 is provided on the sliding seat 9, and the connecting block 19 passes through a relief groove 11 and connects to the chain 18.

[0056] This embodiment 6 provides a more detailed structure of the transmission mechanism based on embodiment 5. The transmission mechanism includes a transmission shaft 14 rotatably mounted on the sliding seat 9 and connected to the output end of the reducer 12, a drive sprocket 15 mounted on the transmission shaft 14, several mounting shafts 16 mounted in the sliding seat 9, driven sprockets 17 mounted on the mounting shafts 16, and a chain 18 mounted between the drive sprocket 15 and the driven sprockets 17.

Since the connecting block 19 is installed on the chain 18, the chain 18 drives the connecting block 19 to move synchronously. The connecting block 19 drives the sliding seat 9 to slide on the sliding seat 9, so that the sliding seat 9 can drive the drilling and splitting mechanism to move, thereby facilitating the adjustment of the drilling and splitting distance of the drilling and splitting mechanism.

[0066] The hydraulic cylinder 24 of this invention is connected to the hydraulic station on the tunnel boring machine. When in use, the hydraulic cylinder 24 is started, and the hydraulic cylinder 24 pushes the connecting seat 23 to move. The connecting seat 23 drives the sliding seat 9 to move synchronously, and drives the sliding seat 9 to move, thereby facilitating the adjustment of the position of the drilling and splitting mechanism.

[0067] Example 9, as Figure 1-7 As shown, the present invention provides a drilling and splitting integrated system for handling pressure chamber obstacles under pressure, including a frame 2 mounted on a shield machine cutterhead 1, a sliding mechanism slidably mounted on the frame 2, a drilling and splitting mechanism mounted on the sliding mechanism and capable of passing through the shield machine cutterhead 1 to drill and split boulders, and a sealing mechanism mounted on the frame 2 and slidably connected to the drilling and splitting mechanism for sealing the drilling and splitting mechanism.

[0068] The sliding mechanism includes a sliding seat 9 slidably mounted on the frame 2, a sliding mounting seat 10 slidably mounted on the sliding seat 9 and connected to the drilling and splitting mechanism, and a driving mechanism mounted on the sliding seat 9 and connected to the sliding mounting seat 10 for driving the sliding mounting seat 10 to reciprocate.

[0069] The top of both sides of the sliding seat 9 is provided with a sliding plate B25, and the bottom of the sliding mounting seat 10 is provided with a slider B26, which is slidably mounted on the sliding plate B25.

[0070] Based on embodiment 4, this embodiment 9 provides a more detailed connection structure for the sliding seat 9 and the sliding seat 9. The top of both sides of the sliding seat 9 is provided with a sliding plate B25, and the bottom of the sliding mounting seat 10 is provided with a slider B26. The slider B26 is slidably mounted on the sliding plate B25.

[0071] In this invention, two sliders B26 are respectively disposed on the top sides of the sliding seat 9 and are integral with the sliding seat 9. The sliders B26 are slidably mounted on the sliding plate B25. The cooperation between the sliders B26 and the sliding plate B25 can effectively reduce the friction of the sliding seat 9 during sliding.

[0072] Example 10, as Figure 1-7 As shown, the present invention provides a drilling and splitting integrated system for handling pressure chamber obstacles under pressure, including a frame 2 mounted on a shield machine cutterhead 1, a sliding mechanism slidably mounted on the frame 2, a drilling and splitting mechanism mounted on the sliding mechanism and capable of passing through the shield machine cutterhead 1 to drill and split boulders, and a sealing mechanism mounted on the frame 2 and slidably connected to the drilling and splitting mechanism for sealing the drilling and splitting mechanism.

[0073] The drilling and splitting mechanism includes an anchoring rotary device 27 mounted on a sliding mechanism, a splitting rod 28 mounted on the output end of the anchoring rotary device 27 and slidably inserted into a sealing mechanism, and a drill bit 30 mounted at the end of the splitting rod 28.

[0074] This embodiment 10 provides a more detailed structure of the drilling and splitting mechanism based on embodiment 1. The drilling and splitting mechanism includes an anchoring rotator 27 disposed on the sliding mechanism, a splitting rod 28 disposed on the output end of the anchoring rotator 27 and slidably inserted into the sealing mechanism, and a drill bit 30 disposed at the end of the splitting rod 28.

[0075] In this invention, the anchoring rotary device 27 and the splitting rod 28 are respectively connected to the hydraulic station on the tunnel boring machine. During use, when drilling a boulder, the anchoring rotary device 27 is activated, which drives the splitting rod 28 to rotate. The splitting rod 28 drives the drill bit 30 to rotate synchronously, thereby drilling a hole in the boulder. After drilling is completed, the anchoring rotary device 27 stops rotating, and the splitting rod 28 is activated to split the boulder. This achieves both drilling and splitting of the boulder, improving the efficiency of boulder processing.

[0076] In order to completely conceal the top post 29 within the splitting rod 28, the top of the top post 29 is arc-shaped, thereby allowing the sealing sleeve 6 to fit snugly against the splitting rod 28 and improving the sealing performance of the sealing sleeve 6 against the splitting rod 28.

[0077] The splitting rod used in this invention is existing technology and can be purchased and used directly on the market.

[0078] Working principle: When using this invention, the hydraulic cylinder 24 is activated, which pushes the connecting seat 23 to move. The connecting seat 23 drives the sliding seat 9 to move synchronously, and drives the sliding seat 9 to move, making an initial adjustment to the position of the drilling and splitting mechanism. Then, the hydraulic pump 13 is activated, which drives the reducer 12 to run. The reducer 12 drives the transmission shaft 14 to rotate, and the transmission shaft 14 drives the drive sprocket 15 to rotate. The drive sprocket 15 drives all the driven sprockets 17 to rotate synchronously through the chain 18. Since the connecting block 19 is installed on the chain 18, the chain 18 drives the connecting block 19 to move synchronously. The connecting block 19 drives the sliding seat 9 to slide on the sliding seat 9, so that the sliding seat 9 can drive the drilling and splitting mechanism to move. Then, the high-pressure ball valve 4 is opened, so that the drill bit 30 comes into contact with the boulder. When drilling into the boulder, the anchoring rotary device 27 is activated, which drives the splitting rod 28 to rotate. The splitting rod 28 drives the drill bit 30 to rotate synchronously, thereby drilling into the boulder. After drilling into the boulder, the anchoring rotary device 27 stops rotating, and the splitting rod 28 is activated. The splitting rod 28 drives the top column 29 to move outward, thereby splitting the boulder through the top column 29, which facilitates the splitting of the boulder.

[0079] The high-pressure ball valve 4, reducer 12, hydraulic pump 13, hydraulic cylinder 24 and anchoring rotary device 27 used in this invention are existing technologies and can be purchased and used directly on the market. Therefore, the structure, circuit and principle of the high-pressure ball valve 4, reducer 12, hydraulic pump 13, hydraulic cylinder 24 and anchoring rotary device 27 will not be described in detail here.
