Description

Technical Field

[0001] The utility model relates to a supporting device for disassembling and assembling a tunnel boring machine, a tunnel boring machine main machine and a tunnel boring machine, belonging to the technical field of tunnel boring equipment. Background Art

[0002] With the diversification of shield tunnel construction, more and more tunnel shield projects have put forward construction requirements for equipment disassembly and assembly periods. In slurry shield projects, the slurry shield machine includes a slurry circulation system including slurry feeding, slurry discharge, and flushing. For example, the shield machine slurry circulation system disclosed in the Chinese invention patent application with application publication number CN109209404A includes a main slurry feeding pipeline, multiple slurry feeding branches, a main slurry discharge pipeline, and multiple slurry discharge branches. Some of these pipelines need to be connected to the rear baffle of the shield body and communicate with the air cushion tank between the front and rear baffles of the shield body. Some need to pass through the rear baffle of the shield body and connect to the front baffle and communicate with the slurry tank between the cutterhead and the front baffle. Still others need to pass through the rear baffle and the front baffle of the shield body and connect to the cutterhead. Due to the large number of pipelines in the mud circulation system and the many motion control components contained in the shield body, a large number of electrical control boxes, hydraulic control valve groups, mud pipelines (some mud pipelines are directly connected to the shield rear partition, and some need to pass through the shield rear partition, but all need to be fixed) and other supporting equipment are distributed in the shield area behind the shield rear partition. These devices are often randomly fixed on site, that is, some mounting plates, support plates, pipe clamps and other fixing devices are fixed on site in suitable free positions in the shield body. The mud pipeline is fixed by the pipe clamp, and the electrical control box and hydraulic control valve group are installed and fixed by the mounting plate and support plate respectively.

[0003] However, due to space and structural limitations, workers lacked a suitable standing position during construction, making installation and disassembly operations extremely inconvenient (this includes securing fixtures such as mounting plates, support plates, and pipe clamps within the shield, as well as securing the electrical control box to the mounting plate, the hydraulic control valve assembly to the support plate, and the mud pipeline to the pipe clamps, and the same applies to disassembly). This significantly reduced construction efficiency, making it impossible to meet the required assembly and disassembly schedule. Furthermore, labor costs also contributed to high construction costs. Furthermore, for some special projects requiring the installation and disassembly of a manhole in a separate tunnel due to construction constraints, the process of securing and removing the manhole to and from the shield's rear bulkhead was also extremely inconvenient. Utility Model Content

[0004] The purpose of the present utility model is to provide a support device for disassembling and assembling a tunnel boring machine, so as to solve the problems in the prior art of inconvenience in installation and disassembly of electrical control boxes, hydraulic control valve groups, and mud pipelines on-site in the rear partition area of ​​the shield body due to space limitations, long construction period, low construction efficiency, and high construction costs; the purpose of the present utility model is also to provide a tunnel boring machine main unit and a tunnel boring machine, so as to solve the above problems.

[0005] In order to achieve the above-mentioned purpose, the supporting device for disassembling and assembling a roadheader in the present invention adopts the following technical solutions:

[0006] The support device for the disassembly and assembly of the tunnel boring machine includes a main support frame.

Bolt holes are provided on the upper connecting plates 13 so as to be fixedly connected to the shield body rear partition 100 by bolts. In addition, the two upper side beams 11 are respectively provided with first lifting ears 14 ( Figure 3 As shown), the first lifting lugs 14 constitute a lifting structure on the main support frame, and the number and fixed positions of the first lifting lugs 14 are determined according to the center of gravity of the support device.

[0074] The middle-level support beam 2 includes two parallel middle-level side beams 21 and a middle-level intermediate beam connected between the two middle-level side beams 21. The middle-level intermediate beam comprises five sections of detachably connected middle-level beam bodies 22. The middle-level beam bodies 22 at each end are fixedly connected to the two middle-level side beams 21, respectively. The middle-level beam body 22 located in the center constitutes a replaceable beam body. Except for the middle-level beam body 22, the remaining middle-level beam bodies 22 are all fixed in place with pipe clamps. The rear ends of the two middle-level side beams 21 are each provided with a middle-level connecting plate 23. The middle-level connecting plate 23 constitutes the connection structure of the middle-level support beam 2 for detachable and fixed connection with the shield body rear bulkhead 100. The middle-level connecting plate 23 is provided with bolt holes for fixed connection with the shield body rear bulkhead 100.

[0075] The lower support beam 3 comprises two parallel lower side beams 31 and a lower middle beam connected between the two lower side beams 31. The lower middle beam comprises three detachably connected lower beam sections 32. The lower beam sections 32 at each end are fixedly connected to the two lower side beams 31, while the lower beam section 32 in the middle is a replaceable section. Pipe clamps are installed on the middle lower beam section 32 and the two lower side beams 31. Lower connecting plates 33 are provided at the rear ends of the two lower side beams 31. These plates form the connection structure of the lower support beam 3 for detachable and fixed connection to the shield rear bulkhead 100. Bolt holes are provided in the lower connecting plates 33 for secure connection to the shield rear bulkhead 100.

[0076] The spacing between the two upper side beams 11 of the upper support beam 1 is smaller than the spacing between the two middle side beams 21 of the middle support beam 2. The connecting member between the upper support beam 1 and the middle support beam 2 is an upper connecting member 4. There are two upper connecting members 4 and they are arranged symmetrically. Specifically, the upper connecting member 4 includes an upper upright 41, a lower upright 42, and a cross bar 43 fixed between the upper upright 41 and the lower upright 42. The upper end of the upper upright 41 is detachably connected to the upper side beam 11, and the lower end of the lower upright 42 is detachably connected to the middle side beam 21. The upper upright 41 and the cross bar 43, as well as the lower upright 42 and the cross bar 43, are both detachably connected. Therefore, the upper upright 41 and the lower upright 42 are both replaceable.

[0077] The distance between the two lower side beams 31 of the lower support beam 3 is smaller than the distance between the two upper side beams 11 of the upper support beam 1. The connecting member between the lower support beam 3 and the middle support beam 2 is the lower connecting member 5. The lower connecting member 5 in this embodiment is a vertical column. The upper end of the vertical column is detachably connected to the middle beam body 22 of the middle support beam 2, and the lower end is detachably connected to the lower side beam 31 of the lower support beam 3, so the lower connecting member 5 is a replaceable component.

[0078] The three layers of support beams are all C-shaped, and the spacing between the side beams of each layer of support beams is different. This is to achieve the main drive 200 ( Figure 1 As shown, the main drive 200 and the mud pipelines 300 are also avoided. Because the positions of the main drive 200 and the mud pipelines 300 are pre-designed, the structure and shape of the support device can only be adapted to the layout of the main drive 200 and the mud pipelines 300. Furthermore, the position of each pipe clamp fixing point on the main support frame and the structure of the pipe clamp installed at each pipe clamp fixing point are designed to match the corresponding mud pipeline 300.

[0079] In addition, the main support frame is also provided with a mounting plate fixing position for fixing the mounting plate for the electrical control box and a support plate fixing position for fixing the support plate for the hydraulic control valve group. Multiple mounting plate fixing positions and support plate fixing positions can be provided as needed, or only one of each can be provided. The specific installation position can be determined randomly, as long as it does not affect the layout of the mud pipeline 300, such as on the upper connecting member 4, on the upper side beam 11, on the middle side beam 21, or on the upper beam body 12. Of course, in other embodiments, the mounting plate fixing position and the support plate fixing position can be omitted, and the electrical control box and the hydraulic control valve group can be directly installed on the main support frame. In this case, it is only necessary to set the control box installation position and the valve group installation position at the above-mentioned appropriate positions of the main support frame.

[0080] like Figures 2 to 4As shown, the secondary support frame 6 comprises two independently arranged independent frames. The rear end of each independent frame is fixedly connected to the main support frame. The front end of each independent frame is cantilevered and is provided with a fixing structure for removably fixing to the rear shield partition 100 of the tunnel boring machine. Specifically, each independent frame includes a crossbeam 61 extending forward and backward, a vertical connecting frame 62 fixed to the front end of the crossbeam 61, a connecting column 63 fixed to the rear end of the crossbeam 61, and a diagonal brace 64 fixed between the crossbeam 61 and the vertical connecting frame 62. The vertical connecting frame 62 is provided with bolt holes, and the vertical connecting frame 62 forms a fixing structure for removably fixing to the rear shield partition 100. The independent frames are fixed to the main support frame via the connecting column 63. The upper end of the connecting column 63 is removably connected to the crossbeam 61, and the lower end is removably connected to the upper beam body 12. Therefore, the connecting column 63 is also a replaceable component.

[0081] like Figure 12 and Figure 13 As shown in the figure, all the above-mentioned replaceable parts are marked in gray. When the support device is suitable for excavating tunnel boring machines of different diameters, the overall size of the support device can be changed by simply removing the replaceable parts and replacing them with parts of appropriate length. The support device can also be fixed to the rear partition of the tunnel boring machine's shield and to ancillary equipment such as the electrical control box, hydraulic control valve group, mud pipeline, etc., which greatly improves the versatility of the support device.

[0082] Taking into account the universal characteristics of the support device, the layout of the mud pipeline for tunnel boring machines of different excavation diameters may be different, so the position and number of pipe clamp fixing positions may change, and even some pipe clamp fixing positions may become mounting plate fixing positions or support plate fixing positions. Similarly, the original mounting plate fixing positions or support plate fixing positions may also become pipe clamp fixing positions. Therefore, it is only necessary to set more bolt mounting holes on the various components of the main support frame to realize the detachable connection of the pipe clamp, the mounting plate for the electrical control box and the support plate for the hydraulic control valve group, and randomly determine the pipe clamp fixing position, the mounting plate fixing position or the support plate fixing position according to actual needs.

[0083] Combine Figures 2 to 4 as well as Figure 5 and Figure 6As shown, the auxiliary support frame 6 is provided with a support structure for supporting the man cabin 8. In this embodiment, the support structure is a support rail 65 respectively provided on the top surface of the two cross beams 61. A plurality of guide plates 81 are fixed to the left and right sides of the man cabin 8, each of which has a groove. The man cabin 8 is clamped on the support rail 65 through the plurality of grooves, so that the support rail 65 can not only support the man cabin 8, but also guide the man cabin 8 to slide forward and backward along the excavation direction on the support rail 65. When installing the man cabin 8, the man cabin 8 can be directly hoisted onto the auxiliary support frame 6. With the support and guided sliding of the support rail 65, the man cabin 8 can be moved forward until it can be installed on the rear partition 100 of the shield body. This design is suitable for special projects that require the disassembly and assembly of the man cabin in a separate hole, making the disassembly and assembly of the man cabin more convenient.

[0084] like Figure 3 and Figure 4 As shown, each independent frame is secured to its crossbeam 61 with a second lifting lug 66. This second lifting lug 66 constitutes the lifting structure on the secondary support frame 6 for connection to the lifting equipment. When the cabin 8 is installed with the front shield rather than being disassembled separately, the connection between the connecting column 63 and the main support frame can be released, and the independent frame can then be removed using the second lifting lug 66, achieving detachment of the secondary support frame 6. Of course, even with the secondary support frame 6, the second lifting lug 66 can also be used to lift the entire support assembly. Therefore, the number and fixed positions of the second lifting lugs 66 are determined based on the center of gravity of the support assembly.

[0085] like Figure 4 、 Figure 7 and Figure 8 As shown, both the main support frame and the auxiliary support frame 6 are provided with a mounting structure for detachably mounting the personnel support platform 9. The mounting structure on the main support frame is a first mounting block 15 fixed on the upper side beam 11, and the mounting structure on the auxiliary support frame 6 is a second fixing block 67 fixed on the crossbeam 61. The number and position of the first mounting block 15 and the second fixing block 67 are determined according to needs. The structures of the first mounting block 15 and the second fixing block 67 are the same. Taking the second fixing block 67 as an example, combined with Figure 9 、 Figure 10 and Figure 11 As shown, the second fixing block 67 is provided with a socket 671 for the insertion tongue 91 on the personnel support platform 9 to be inserted from top to bottom. The second fixing block 67 is also provided with a bolt mounting hole 672 that is connected to the socket 671 and is used to install a bolt 10 to retain the insertion tongue 91. Specifically, in this embodiment, the bolt mounting hole 672 is a threaded hole, and the insertion tongue 91 is provided with a clear hole. By screwing the bolt 10, it can be inserted into the clear hole of the insertion tongue 91, thereby retaining the personnel support platform 9, preventing it from shaking or even falling out upward, and ensuring the safety of construction workers.

[0086] The use process of the support device for disassembling and assembling a roadheader in the utility model is as follows:

[0087] During installation, first, at the assembly site or factory, the pipe clamps 7, the mounting plate for the electrical control box, and the support plate for the hydraulic control valve assembly are secured to the appropriate locations on the main support frame. The corresponding mud pipelines 300 are secured using the pipe clamps 7, the mounting plate for the electrical control box, and the support plate for the hydraulic control valve assembly. Of course, for electrical control boxes and hydraulic control valve assemblies that do not require mounting plates, they are directly secured to the appropriate locations on the main support frame, securing the electrical, hydraulic, and flow-related equipment. After the mainframe's front shield, main drive, center swivel joint, and other structural components are assembled, the support assembly and its associated equipment are lowered into the well using the first lifting lug 14 or second lifting lug 66 on the support assembly. The main and auxiliary support frames are then bolted to the shield's rear bulkhead 100 on-site. After the support device is installed and secured, the first mounting block 15 and the second mounting block 67 are fixed as needed. Both mounting blocks can also be fixed in advance. Then, a personnel support platform 9 is installed on the mounting blocks to provide temporary support for personnel during equipment installation operations, such as connecting pipes and wiring. After the equipment is installed, the personnel cabin 8 is hoisted onto the secondary support frame 6. This supports and pulls the cabin forward, and finally, it is installed on the shield's rear bulkhead 100. After equipment installation is complete, the personnel support platform 9 is removed.

[0088] During the installation process, if the actual space allows and there is a suitable standing position on site, it is also possible to choose not to install the personnel support platform 9, or if the presence of the personnel support platform 9 does not affect subsequent operations, it is also possible to choose not to remove the personnel support platform 9. Of course, if the cabin 8 can be installed together with the front shield, the auxiliary support frame 6 can be eliminated to achieve the purpose of reducing the weight of the support device.

[0089] To dismantle the shield, first slowly pull out the manhole 8 using the lifting ropes, supported by the auxiliary support frame 6. Then, install the personnel support platform 9 on the appropriate mounting blocks, disconnect the equipment, and connect the support device to the lifting equipment using the lifting lugs on the main support frame or auxiliary support frame 6. Then, remove the bolts securing the support device to the shield's rear bulkhead 100, and pull out the support device along with the electrical control box, hydraulic control valve assembly, and mud pipeline. Of course, if the manhole 8 is installed with the front shield, then, after removing the auxiliary support frame 6, the manhole 8 can be removed first, followed by the removal of the support device.

[0090] The support device for disassembling and assembling a tunnel boring machine according to the utility model allows the electrical control box, hydraulic control valve group, mud pipeline and other supporting equipment to be disassembled and assembled together with the support device during disassembly and assembly. That is, the electrical control box, hydraulic control valve group, mud pipeline and other equipment that originally required on-site installation can be pre-installed on the support device. Then, as the support device is hoisted into place as a whole, the electrical control box, hydraulic control valve group, mud pipeline and other equipment can be fixed by simply fixing the support device to the rear partition of the shield body. There is no need to fix fixing devices such as mounting plates, support plates, and pipe clamps on-site, nor is there any need to fix the electrical control box to the mounting plate, fix the hydraulic control valve group to the support plate, and fix the mud pipeline to the pipe clamps on-site. This makes installation more convenient and improves construction efficiency. At the same time, since the support device is detachable, the support device and the electrical control box, hydraulic control valve group, mud pipeline and other equipment on it can be removed together during disassembly, which also improves construction efficiency. Therefore, the support device of the present invention can greatly facilitate the operation of the disassembly and assembly machine, improve construction efficiency, and thus meet the disassembly and assembly period requirements and reduce construction costs.

[0091] Example 2 of the support device for disassembling and assembling a roadheader in the present utility model:

[0092] like Figure 14 As shown, unlike Example 1, the auxiliary support frame in this embodiment is an integral frame structure, and the two independent frames are fixed by a connecting frame 68. The two independent frames can be hoisted as a whole. At the same time, the connecting frame 68 is detachably connected to the two independent frames and to the main support frame. Therefore, when it is suitable for tunnel boring machines with different excavation diameters, the connecting frame 68 needs to be replaced as a whole.

[0093] In other embodiments of the support device for disassembling and assembling a roadheader, the mounting structures for the removable personnel support platform on the main and auxiliary support frames can be directly bolted onto the holes. This means that no additional mounting blocks are required, and holes can simply be drilled directly into the corresponding beams. In other embodiments, if site space permits and a suitable standing position is available, no mounting structure of any kind may be required, meaning that a personnel support platform need not be installed.

[0094] In other embodiments of the support device for the disassembly and assembly machine of the tunnel boring machine: the lifting structure on the main support frame and the lifting structure on the auxiliary support frame can be set as hooks. Of course, there is no need to fix the components separately, but holes can be directly drilled at appropriate positions of the beam body to serve as lifting holes.

[0095] In other embodiments of the support device for the disassembly and assembly machine of the tunnel boring machine: the local structure of the main support frame can be changed, for example, some connecting beams can be added to the upper support beam to achieve that the rear end, middle part and front end of the auxiliary support frame are fixedly connected to the main support frame, or that the front and rear ends of the auxiliary support frame are fixedly connected to the main support frame, instead of the front end being overhanging.

[0096] In other embodiments of the support device for the disassembly and assembly machine of the tunnel boring machine: the support rail on the main support frame may not extend into the groove of the man cabin guide plate, but rollers are provided at the bottom of the man cabin, and raceways are provided on the support rails. The rollers move in the raceways and can also support and guide the man cabin.

[0097] In other embodiments of the support device for the disassembly and assembly machine of the tunnel boring machine: the support structure on the secondary support frame may not guide the movement of the man cabin, for example, the support structure is the top surface of the main support frame, and bolt mounting holes are provided on the top surface, and when the man cabin is hoisted onto the main support frame, the man cabin is directly fixed.

[0098] In other embodiments of the support device for the tunnel boring machine disassembly and assembly machine: when there are three layers of support beams, the lower ends of the vertical columns between the middle support beams and the lower support beams can also be fixedly connected to the middle beams of the lower support beams.

[0099] In other embodiments of the support device for the disassembly and assembly machine of the tunnel boring machine: the middle beam of the middle-level support beam can also be detachably connected by three beam sections, and in this case the middle beam section is a replaceable beam section.

[0100] In other embodiments of the support device for disassembling and assembling a tunnel boring machine: the support beam may also have only two layers, such as eliminating the lower support beam in Example 1 and retaining only the upper support beam and the middle support beam. The pipe clamp fixing positions originally set on the lower support beam can be set on the middle support beam. Of course, only the upper support beam and the lower support beam can be retained. For special projects that do not require separate in-hole disassembly and assembly of the manhole, the upper support beam can be omitted in addition to omitting the auxiliary support frame. In this case, the pipe clamp fixing positions originally set on the upper support beam can be set on the middle support beam. Of course, in this case, the lower support beam can also be omitted. All pipe clamp fixing positions are on the middle support beam, and the control box mounting position or mounting plate mounting position, valve group mounting position or support plate fixing position are also on the middle support beam.

[0101] In other embodiments of the support device for the tunnel boring machine disassembly and assembly machine: according to the specific layout of the mud pipeline on the tunnel boring machine, the side beams of each support beam can be arranged in alignment up and down, that is, the spacing between the side beams of each support beam is equal, and at this time the connecting parts between the upper and lower layers of support beams are all vertical columns.

[0102] In other embodiments of the support device for a tunnel boring machine disassembly and assembly machine: when the support beams are provided with more than two layers, the middle beam of each layer of support beams can be composed of only one section of beam body, and this section of beam body and the side beams on both sides can be detachably connected so that they can be replaced as a whole to be suitable for tunnel boring machines with different excavation diameters. Of course, they can also be welded and fixed. In this case, a support device for a tunnel boring machine disassembly and assembly machine is only suitable for one type of tunnel boring machine.

[0103] In other embodiments of the support device for the disassembly and assembly machine of the tunnel boring machine: the support beam may not be C-shaped, especially when the main support frame has only one support beam, or when there are multiple layers of support beams, the top and bottom support beams can be set to E-shaped as long as they do not interfere with other equipment. This can increase the connection points with the rear partition of the shield body and make the fixation more secure.

[0104] In the present invention, the main machine of a tunnel boring machine comprises a shield, which includes a rear baffle, and a support device removably secured to the rear baffle. This support device is identical to the support device for disassembling and assembling a tunnel boring machine described in any of the aforementioned embodiments and will not be repeated here. It should be noted that the main machine of the tunnel boring machine can be a slurry shield machine, or a dual-mode (slurry + earth pressure) or tri-mode (slurry + earth pressure + hard rock) tunnel boring machine.

[0105] The embodiment of the tunnel boring machine in the present invention comprises a main machine and supporting equipment. The main machine comprises a shield, which comprises a rear baffle. The shield further comprises a support device detachably secured to the rear baffle. The support device is identical to the support device for assembly and disassembly of the tunnel boring machine described in any of the aforementioned embodiments and will not be repeated here. It should be noted that the tunnel boring machine can be a slurry shield machine, a dual-mode (slurry + earth pressure), or a tri-mode (slurry + earth pressure + hard rock) tunnel boring machine.

[0106] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be based on the claims. Any equivalent structural changes made using the description and drawings of the present invention shall also be included in the scope of protection of the present invention.
