Description

Technical Field

[0001] This invention relates to the field of TBM dismantling technology, and more specifically to a hoisting system for non-destructive dismantling of TBMs. Background Technology

[0002] Typically, after completing the tunneling task of one section, the TBM will be transported to another section for tunneling. Due to the huge size of the TBM, it needs to be disassembled before it can be transported to the next construction section.

[0003] Currently, there are several methods for dismantling TBMs inside the tunnel. The first method is shell-based dismantling without a dedicated dismantling chamber. This involves destructively removing the shield inside the excavated tunnel to ensure the integrity of major components such as the drive unit. This method is labor-intensive, time-consuming, and results in a low integrity rate for the TBM main unit, leading to significant economic losses. The second method involves excavating a dismantling chamber at one end of the tunnel before the TBM reaches its destination. A hoisting system is then installed inside the dismantling chamber to complete the dismantling. This method maintains the integrity of the TBM main unit and is currently the most widely used method for TBM dismantling.

[0004] As TBMs are gradually applied in mining, pumped storage and other fields, the on-site working conditions are becoming more and more complex. Some projects cannot meet the conditions for early excavation and dismantling of the machine chamber. Therefore, the TBM main unit can only be destructively dismantled, resulting in a low integrity rate of the TBM main unit. Summary of the Invention

[0005] The purpose of this invention is to provide a hoisting system for non-destructive dismantling of TBMs, in order to solve the technical problem in the prior art that, in situations where it is impossible to excavate the dismantling chamber, the only option is to perform destructive dismantling of the TBM main unit, resulting in a low integrity rate of the TBM main unit.

[0006] To achieve the above objectives, the technical solution of the TBM non-destructive dismantling hoisting system of the present invention is as follows:

[0007] The TBM non-destructive dismantling hoisting system includes a first track beam and a second track beam for fixing to the tunnel roof. Both the first track beam and the second track beam extend along the front-rear direction of the tunnel and are located on the front and rear sides of the corresponding shields, respectively. A first lifting device is slidably mounted on the first track beam along the front-rear direction of the tunnel, and a second lifting device is slidably mounted on the second track beam along the front-rear direction of the tunnel. The TBM non-destructive dismantling hoisting system also includes a top block bracket for suspending on the first and second lifting devices to support the top blocks of the corresponding shields.

[0008] The beneficial effects are as follows: During the dismantling of a TBM inside a tunnel, the primary problem is the lifting height, followed by the transfer and unloading. In this invention, the lifting height problem is solved by using a lifting device combined with a top block bracket to lift TBM components; suspending the lifting device on a track beam allows for forward and backward movement, thus solving the transfer and unloading problem. This ensures damage-free dismantling of the TBM inside the tunnel, solving the problems of large workload, long construction period, and high cost caused by the need to excavate large dismantling chambers in conventional TBM dismantling methods. It also overcomes the drawbacks of low equipment integrity and significant component loss caused by shell-dismantling methods, ultimately achieving economical and efficient TBM dismantling.

[0009] As a further improvement, at least two of the first track beams and / or the second track beams are arranged at intervals along the left and right directions of the tunnel.

[0010] The beneficial effect is that this design ensures the stability of the component to be lifted during the lifting process.

[0011] As a further improvement, two of the first and second track beams are arranged at intervals along the left and right directions of the tunnel. The TBM non-destructive dismantling hoisting system includes a third and a fourth hoisting device for connecting to the tunnel roof. The third and fourth hoisting devices are located on the front and rear sides of the respective shields, respectively. The third hoisting device is located between the two first track beams in the left and right directions of the tunnel, and the fourth hoisting device is located between the two second track beams in the left and right directions of the tunnel.

[0012] The beneficial effects are: since the first and second lifting devices need to travel on the corresponding track beams, the first and second lifting devices cannot swing at too large an angle. The setting of the third and fourth lifting devices facilitates the lifting of the main drive and the shield side blocks.

[0013] As a further improvement, at least two of the third and / or fourth lifting devices are arranged at intervals in the left and right directions of the tunnel.

[0014] The beneficial effect is that this design ensures the stability of the component to be lifted during the lifting process.

[0015] As a further improvement, the TBM non-destructive dismantling lifting system also includes a main drive bracket for suspending on the third and fourth lifting devices to support the main drive.

[0016] The beneficial effect is that setting up a main drive bracket facilitates the lifting of the main drive.

[0017] As a further improvement, the distance between the first track beam and the second track beam in the front and rear directions of the tunnel is greater than twice the axial width of the corresponding shield.

[0018] The beneficial effect is that this design allows the top block of the shield to be hoisted onto the transport vehicle without moving other parts of the shield, thus improving hoisting efficiency.

[0019] As a further improvement, the third and fourth lifting devices are positioned between the first and second track beams in the longitudinal direction of the tunnel.

[0020] The beneficial effect is that this design can reduce the length of the main drive bracket.

[0021] As a further improvement, the top block bracket includes a base and columns fixed on the base. At least two sets of columns are arranged at intervals in the front-back direction, and each set of columns is provided with a supporting crossbeam. The base is provided with base lifting lugs.

[0022] The beneficial effects are: this design makes the structure of the top block bracket simpler and helps to reduce the number of suspension points.

[0023] As a further improvement, both the first track beam and the second track beam include a traveling beam and at least two sets of hangers. The hangers include anchors for fixing to the tunnel wall and connectors provided on the anchors. The traveling beam is fixed to the anchors by the connectors.

[0024] The beneficial effect is that this design ensures the stability of the traveling beam fixed to the anchor.

[0025] As a further improvement, both the first and second lifting devices include a traveling trolley and a lifting hoist.

[0026] The beneficial effect is that this design enables automatic hoisting. Attached Figure Description

[0041] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0042] Example 1 of the TBM non-destructive dismantling hoisting system of the present invention:

[0043] like Figure 1 and Figure 2 As shown, the TBM non-destructive dismantling hoisting system includes a first track beam 16 and a second track beam 17 for fixing to the top wall of the tunnel 10. The first track beam 16 and the second track beam 17 both extend along the front and rear directions of the tunnel 10 and are located on the front and rear sides of the respective shields.

[0044] In this embodiment, the TBM is a dual-shield TBM, meaning the two shields are a support shield and a front shield. For example... Figure 2 As shown, the support shield includes a top support shield block 11, a left support shield block 12, a bottom support shield block 13, and a right support shield block 14; as Figure 5 As shown, the front shield includes a front shield top center block 26, a front shield top left block 27, a front shield bottom left block 28, a front shield bottom center block 29, a front shield bottom right block 30, and a front shield top right block 31. The front shield top center block 26, the front shield top left block 27, and the front shield top right block 31 together constitute the front shield top block 38, and the front shield bottom left block 28, the front shield bottom center block 29, and the front shield bottom right block 30 together constitute the front shield bottom block 39.

[0045] In this embodiment, a first lifting device 33 is slidably mounted on the first track beam 16 along the front-rear direction of the tunnel, and a second lifting device 34 is slidably mounted on the second track beam 17 along the front-rear direction of the tunnel; the TBM non-destructive dismantling lifting system also includes a top block bracket suspended from the first lifting device 33 and the second lifting device 34 to support the corresponding shield top blocks. In this embodiment, as... Figure 1 As shown, the top block bracket supporting the shield top block 11 is the first top block bracket 15; as Figure 8 As shown, the top block bracket supporting the front shield top block 38 is the second top block bracket 32.

[0046] like Figure 1 and Figure 2 As shown, the first top block bracket 15 includes a base 23 and columns 25 fixed on the base 23. Two sets of columns 25 are arranged at intervals in the front-rear direction. Each set of columns 25 is equipped with a supporting crossbeam 24. The two supporting crossbeams 24 are used to support the top block 11 of the shield. The base 23 is equipped with base lifting lugs, and a first lifting device 33 and a second lifting device 34 are respectively connected to the corresponding base lifting lugs. As shown... Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the first top block bracket 15 and the second top block bracket 32 ​​have the same overall structure, with the only difference being: 1) the base 23 in the first top block bracket 15 is relatively longer, while the base 23 in the second top block bracket 32 ​​is relatively shorter; 2) the two sets of columns 25 in the first top block bracket 15 have the same height, while the two sets of columns 25 in the second top block bracket 32 ​​have a height difference.

[0047] like Figure 2 As shown, two first track beams 16 are arranged at intervals along the left and right directions of the tunnel 10, and each first track beam 16 is equipped with the aforementioned first lifting device 33; two second track beams 17 are arranged at intervals along the left and right directions of the tunnel 10, and each second track beam 17 is equipped with the aforementioned second lifting device 34. This design ensures that the two first lifting devices 33 and the two second lifting devices 34 are respectively hooked onto the base lifting lugs at the four corners of the base 23, guaranteeing the stability of the first top block bracket 15. The second top block bracket 32 ​​is the same.

[0048] In this embodiment, the distance between the first track beam 16 and the second track beam 17 in the front and rear directions of the tunnel 10 is greater than twice the axial width of the corresponding shield.

[0049] like Figure 8 and Figure 9As shown, the TBM non-destructive dismantling lifting system includes a third lifting device 36 and a fourth lifting device 37 fixed to the top wall of tunnel 10. The third lifting device 36 and the fourth lifting device 37 are located on the front and rear sides of the front shield, respectively. The third lifting device 36 is positioned between two first track beams 16 in the left-right direction of tunnel 10, and the fourth lifting device 37 is positioned between two second track beams 17 in the left-right direction of tunnel 10. Since the first lifting devices 33 and 34 need to travel on the corresponding track beams, they cannot sway too much. The arrangement of the third lifting device 36 and the fourth lifting device 37 facilitates the lifting of the main drive 35.

[0050] In this embodiment, the TBM non-destructive dismantling lifting system also includes a main drive bracket 41 for suspending the main drive 35 on the third lifting device 36 and the fourth lifting device 37. The main drive bracket 41 includes transverse H-beams arranged along the left-right direction of the tunnel 10 and longitudinal H-beams arranged along the front-back direction of the tunnel 10. Two transverse H-beams are spaced apart along the front-back direction, and the two ends of the longitudinal H-beams are fixed above the transverse H-beams. Each transverse H-beam has H-beam lifting lugs on both the left and right sides of the longitudinal H-beams.

[0051] In this embodiment, two third lifting devices 36 and two fourth lifting devices 37 are arranged at intervals in the left and right directions of the tunnel 10. This design ensures that the two third lifting devices 36 and the two fourth lifting devices 37 are hooked onto the lifting lugs of the corresponding transverse I-beams, thus guaranteeing the stability of the main drive bracket 41.

[0052] In this embodiment, the third lifting device 36 and the fourth lifting device 37 are positioned between the first track beam 16 and the second track beam 17 in the front-rear direction of the tunnel 10. This design can reduce the length of the main drive bracket 41.

[0053] In this embodiment, the first track beam 16 and the second track beam 17 have the same structure, both including a traveling beam 20 and at least two sets of hangers. Taking the first track beam 16 as an example, as follows... Figure 3 As shown, the hanger includes anchor bolts 18 for fixing to the top wall of tunnel 10 and steel cylinders 19 welded to the anchor bolts 18, the lower end of the steel cylinders 19 being a closed structure; the traveling beam 20 is made of I-beams or H-beams, and the traveling beam 20 is welded to the anchor bolts 18 via the steel cylinders 19. The anchor bolts 18 constitute the anchoring element, and the steel cylinders 19 constitute the connecting element. In other embodiments, the anchoring element can be an anchor cable.

[0054] In this embodiment, the first lifting device 33, the second lifting device 34, the third lifting device 36, and the fourth lifting device 37 have the same structure. Taking the first lifting device 33 as an example, as follows... Figure 4As shown, the first lifting device 33 includes a traveling trolley 21 and a lifting hoist 22, which enables automatic lifting. The lifting hoist can be an electric hoist, a pneumatic hoist, or a manual hoist, etc.

[0055] During the dismantling of a TBM in a blind tunnel, the primary issue is the lifting height, followed by the transfer and unloading problem. In this invention, the lifting height problem is solved by using a lifting device in conjunction with a top block bracket to lift TBM components; the transfer and unloading problem is solved by suspending the lifting device on the track beam, allowing it to move back and forth.

[0056] The specific disassembly steps of the TBM non-destructive disassembly hoisting system of this invention are as follows:

[0057] (1) Remove main unit accessories: Remove the protective cover between the front shield and the support shield, the top propulsion cylinder, the main drive motor and other accessories.

[0058] (2) Remove the supporting shield top block: such as Figure 1 and Figure 2 As shown, disconnect the connecting bolts between the top block 11 of the support shield and the left side block 12 and the right side block 14 of the support shield, and cut open the weld between the top block 11 of the support shield and the left side block 12 and the right side block 14 of the support shield; install the first top block bracket 15 on the first lifting device 33 and the second lifting device 34, and move the top block 11 of the support shield backward through the first top block bracket 15 and place it on the flatbed transport vehicle, support it with square timber, and then transport it out of the hole.

[0059] (3) Remove the left and right side blocks and the bottom block of the support shield: disconnect the connecting bolts between the bottom block 13 of the support shield and the left side block 12 and the right side block 14 of the support shield, and cut open the weld between the bottom block 13 of the support shield and the left side block 12 and the right side block 14 of the support shield; use the first and second lifting devices to lift the left side block 12, the right side block 14 and the bottom block 13 of the support shield respectively and move them to the flatbed transport vehicle to remove the remaining parts of the support shield.

[0060] (4) Remove the top block of the front shield. For example... Figure 6 and Figure 7 As shown, the front shield top block 38 is lifted by the front shield lifting cylinder, the front shield top block 38 is fixed by the anchor rod, the front shield bottom block 39 and the main drive 35 are moved forward as a whole, and the second top block bracket 32 ​​is hoisted by the first lifting device 33 and the second lifting device 34 to lower the front shield top block 38 onto the flatbed transport vehicle, and after being supported by square timber, it is transported out of the tunnel.

[0061] (5) Remove the front shield bottom block. Move the front shield bottom block 39 and the main drive 35 as a whole to the rear. Use the third lifting device 36 and the fourth lifting device 37 to lift the main drive bracket 41 to lift the main drive 35, so that the main drive 35 is separated from the front shield bottom block 39. After the front shield bottom block 39 is removed from under the main drive 35, it is transferred to a flatbed transport vehicle and transported out of the tunnel.

[0062] (6) Remove the main drive. For example... Figure 8 and Figure 9 As shown, the main drive transport vehicle is moved to the bottom of the main drive 35, the main drive 35 is placed on the main drive transport vehicle, and the main drive 35 is transported out of the cave as a whole.

[0063] This invention ensures that TBMs can be dismantled without damage in blind tunnels, solving the problems of large workload, long construction period, and high cost caused by the need to excavate large dismantling chambers in conventional TBM dismantling methods. It also solves the drawbacks of low equipment integrity and large loss of equipment parts caused by shell disposal dismantling methods, ultimately achieving economical and efficient TBM dismantling.

[0064] Example 2 of the TBM non-destructive dismantling hoisting system of the present invention:

[0065] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, two first track beams and two second track beams are arranged at intervals along the left and right directions of the tunnel. In this embodiment, only one first track beam and one second track beam are arranged and located at the top of the tunnel. To ensure balance, each lifting device is equipped with two lifting points connected to the top block bracket.

[0066] Example 3 of the TBM non-destructive dismantling hoisting system of the present invention:

[0067] The difference between this embodiment and Embodiment 1 is that, in Embodiment 1, the TBM non-destructive dismantling lifting system includes a third and a fourth lifting device for connecting to the tunnel roof. In this embodiment, the third and fourth lifting devices are not provided; the first and second lifting devices are still used to lift the remaining components of the TBM.

[0068] Example 4 of the TBM non-destructive dismantling hoisting system of the present invention:

[0069] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, two third and four lifting devices are arranged at intervals in the left-right direction of the tunnel. In this embodiment, one third and one fourth lifting device are arranged and located at the top of the tunnel. To ensure balance, each lifting device is provided with two lifting points connected to the main drive bracket.

[0070] Example 5 of the TBM non-destructive dismantling hoisting system of the present invention:

[0071] The difference between this embodiment and Embodiment 1 is that, in Embodiment 1, the TBM non-destructive dismantling lifting system also includes a main drive bracket for suspending on the third and fourth lifting devices to support the main drive. In this embodiment, instead of a main drive bracket, lifting lugs are provided on the main drive, and the third and fourth lifting devices lift the main drive through these lugs.

[0072] Example 6 of the TBM non-destructive dismantling hoisting system of the present invention:

[0073] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the hanger includes an anchor rod 18 and a steel cylinder 19 welded to the anchor rod 18, and the traveling beam 20 is welded and fixed to the anchor rod 18 via the steel cylinder 19, wherein the steel cylinder 19 constitutes a connecting member. In this embodiment, as...
