Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine technology, and in particular to a translation device for the main control room. Background Technology

[0002] As the core equipment in tunnel construction, the main control room of the tunnel boring machine (TBM) plays a crucial role in operation and control during construction. However, in actual construction, due to the size constraints of the launching shaft, the initial installation location of the main control room often encroaches on safety passages and the working space of the inner segment hoist. This not only hinders the safe passage of construction personnel but also affects the normal hoisting of segments, potentially leading to serious safety hazards, especially during the transportation of large segments.

[0003] To address these issues, the industry typically employs a phased deployment approach: during the initial launch phase, the main control room is temporarily fixed to the side of the launch shaft. Once the tunnel boring machine (TBM) enters the tunnel, the main control room's position is adjusted to create space for a safe passage and segment hoisting. While this approach ensures subsequent construction efficiency and safety, it places high demands on the reliability and ease of use of the main control room relocation device.

[0004] In existing technologies, the main control room relocation is mainly carried out in the following two ways:

[0005] 1. Screw-type movement, which achieves the displacement of the main control room through threaded transmission, can achieve precise control, but it suffers from slow movement speed and low work efficiency. In addition, this method lacks stability under tunnel boring machine vibration conditions, posing a safety hazard.

[0006] 2. Roller-type movement, which uses a combination of tracks and rollers, can increase the speed of movement, but it is prone to tipping over in confined spaces due to a shift in the center of gravity, especially when moving on uneven surfaces in tunnels.

[0007] In summary, existing translation technologies all have significant limitations and cannot simultaneously meet the multiple requirements of construction efficiency, ease of operation, and safety and stability. Therefore, there is an urgent need to develop a tunnel boring machine main control room displacement device capable of achieving rapid, stable, and reliable translation to ensure construction safety and improve operational efficiency. Summary of the Invention

[0008] This application provides a main control room translation device that ensures a smooth and reliable translation process.

[0010] A towing mechanism that travels on a ground track in the construction area;

[0011] The support structure includes multiple parallel support members fixed to the front to rear sides of the bottom of the main control room; wherein, the support members include a first support member respectively disposed on the front and rear sides of the bottom of the main control room, and a second support member disposed between the front and rear sides of the bottom of the main control room; along the length direction of the support member, the first support member has multiple sets of first fixing holes.

[0012] A fixed support is fixed to the towing mechanism and correspondingly connected to the first support member. The fixed support has multiple sets of second fixing holes that are adapted to the first fixing hole.

[0013] A sliding support is fixed to the towing mechanism and correspondingly connected to a second support member. The sliding support is constructed with a sliding limiting groove, and the second support member is slidably connected in the sliding limiting groove, with the sliding direction set to the length direction of the support member.

[0014] When the main control room is in a moving state, the second support member slides in the sliding limit groove;

[0015] When the main control room is stationary, the second fixing hole is fixedly connected to the first fixing hole by fasteners.

[0016] In some feasible embodiments, the support is constructed of H-beams, with the upper flange plate fixed to the bottom of the main control room and the lower flange plate connected to a fixed support or a sliding support.

[0017] In some feasible embodiments, the first fixing hole is formed on the lower flange of the first support member, and each set of first fixing holes includes two first fixing holes symmetrically located on both sides of the web.

[0018] In some feasible implementations, the fixed support is constructed of H-beams, and the second fixing hole is formed on the upper flange plate.

[0019] In some possible implementations, the first support member is connected to at least two fixed supports, and the second fixing hole on each fixed support corresponds to a portion of the first fixing hole.

[0020] In some feasible implementations, the length of the line connecting the at least two fixed supports is not less than half the length of the first support member.

[0021] In some feasible embodiments, the sliding support includes a support body and a guide rail component. The support body is constructed of H-beams, and the guide rail component includes a first track structure and a second track structure fixed to the upper flange of the support body. The first track structure and the second track structure form a sliding limiting groove.

[0022] In some feasible implementations, the width of the sliding limiting groove is adapted to the width of the lower flange of the central support.

[0023] In some feasible embodiments, at least two sliding supports are connected to the second support member, and each sliding support member has a third fixing hole on its first track structure and second track structure for the anti-slip member to pass through, the anti-slip member restricting the sliding of the second support member.

[0024] In some feasible implementations, a limiting hole is formed between the first end track structure and the second track structure, the width of which is adapted to the web of the middle support member.

[0025] Beneficial effects: This utility model achieves the translation of the main control room by setting a support structure at the bottom of the main control room and setting fixed supports and sliding supports on the rear trailer. The second support member is slidably connected to the sliding support, and the first support member is fixedly connected to the fixed support to reliably fix the position of the main control room after translation. The above structure can realize the rapid and stable translation of the main control room, and ensure that there is no deviation or overturning during the translation and sliding process. After the movement, the position of the main control room can be reliably fixed, avoiding shaking caused by vibration during construction, improving the construction efficiency of the tunnel boring machine, and ensuring construction safety.

[0040] Generally, the main control room 1 is the central system for the operation and monitoring of the entire tunnel boring machine. In this embodiment, the main control room 1 is a movable functional cabin with independent space. Therefore, the main control room 1 needs the stability of a "building-like structure" in terms of function, but it must also achieve stable and safe mobility during construction. This is the core contradiction that existing technologies struggle to balance.

[0041] This embodiment provides a main control room 1 translation device, which is installed at the bottom of the main control room 1, such as... Figure 1-8 As shown, the system includes a towing mechanism, a support structure, a fixed support 200, and a sliding support 300. The towing mechanism travels on a ground track in the construction area, providing structural support for the main control room 1. The towing mechanism remains stationary when the main control room 1 is moved. The support structure is located at the bottom of the main control room 1. The fixed support 200 and the sliding support 300 are fixed to the towing mechanism. The main control room 1 is moved by sliding the support structure on the sliding support 300. Simultaneously, the support structure and the fixed support 200 are connected and fixed to lock the main control room 1 after the movement.

[0042] For example, a rear-mounted trailer with a towing mechanism assembled from structural components is generally used for equipment installation, material transportation, and personnel passage.

[0043] Among them, such as Figure 1 As shown, the support structure includes multiple parallel support members fixed to the bottom of the main control room 1 from the front to the rear. For example, the support members extend along the left-right direction of the main control room 1, that is, perpendicular to the front-back direction. In this structure, the translation direction of the main control room 1 is set to left-right translation.

[0044] Specifically, the support components include a first support component 2 and a second support component 3. For example... Figure 3-6 As shown, there are at least two first support members 2, with at least one on the front side and at least one on the rear side of the bottom of the main control room 1. Furthermore, there are at least two second support members 3, evenly distributed within the area between the first support members 2 and the rear side of the bottom of the main control room 1. Based on the arrangement of the first support members 2 and the second support members 3, the bottom surface of the main control room 1 forms a large-area support structure composed of multiple first support members 2 and second support members 3. Because the support members are distributed from the front to the rear of the main control room, the provided support force is more comprehensive and stable, and it is less prone to shaking.

[0045] In addition, the towing mechanism is equipped with a fixed support 200 and a sliding support 300. The fixed support 200 is connected to the first support member 2, and the sliding support 300 is connected to the second support member 3. For example... Figure 2As shown, the first support member 2 has multiple sets of first fixing holes 4 along its length, and the fixed support 200 has multiple sets of second fixing holes 5 that are adapted to the first fixing holes 4. The sliding support 300 is constructed with a sliding limiting groove 304, and the second support member 3 is slidably connected in the sliding limiting groove 304, and the sliding direction is set to the length direction of the support member.

[0046] Based on the connection relationship between the fixed support 200 and the sliding support 300 and the first support 2 and the second support 3 respectively, when the main control room 1 is in a moving state, the second support 3 can slide in the sliding limiting groove 304. The sliding limiting groove 304 can limit the sliding range of the first support 2 to the length direction of the support, that is, the left and right direction in this embodiment, to avoid shaking during the sliding of the main control room 1. When the main control room 1 is stationary, the first fixing hole 4 on the first support 2 and the second fixing hole 5 on the fixed slide are fixedly connected by fasteners, which ensures the stability of the main control room 1.

[0047] To prevent friction between the first support member 2 and the fixed support 200 during the translation of the main control room 1, lubricating oil is filled on the sliding contact surface of the first support member 2 and the fixed support 200 to reduce wear caused by friction and extend the service life.

[0048] Specifically, all supporting components are constructed of H-beams. Therefore, the upper flange of the supporting component is fixed to the bottom of the main control room 1, and the lower flange is connected to the fixed support 200 or the sliding support 300. In other words, the H-beams are all horizontally arranged. For example, the upper flange of the H-beam is welded to the bottom of the main control room 1.

[0049] Regarding the arrangement of the first fixing hole 4, the first fixing hole 4 is opened on the lower flange plate of the first support member 2, and each set of first fixing holes 4 includes two first fixing holes 4 symmetrically located on both sides of the web plate. In this way, after the first support member 2 and the fixed support 200 are fixedly connected, the force on both sides of the web plate of the first support member 2 is even, avoiding tilting.

[0050] Correspondingly, such as Figure 4 , 5 As shown, the fixed support 200 is constructed as an H-beam. The second fixing hole 5 is opened on the upper flange plate of the H-beam of the fixed support 200. The first support member 2 and the lower flange plate correspond to and contact the upper flange plate of the fixed support 200. The positions of the first fixing hole 4 and the second fixing hole 5 are matched. The first support member 2 and the fixed support 200 can be fixed by fasteners.

[0051] The number of mating parts between the first support member 2 and the fixed support 200 is not specifically limited, as long as the mating between the fixed support 200 and the first support member 2 ensures the stability of the main control room 1 during both the translation process and the static state. For example, each first support member 2 is connected to at least two fixed supports 200, and the second fixing hole 5 on each fixed support 200 corresponds to a portion of the first fixing hole 4.

[0052] To ensure the stability of the main control room 1 on the fixed support 200 via the first support member 2, the length of the line connecting at least two fixed supports 200 shall not be less than half the length of the first support member. On this basis, the supporting force of all fixed supports 200 on the main control room 1 can cover more than half of the bottom surface of the main control room 1, so as to prevent the main control room 1 from tilting or even overturning during the sliding and translation process.

[0053] Specifically, all fixed supports 200 can be constructed to have the same or different lengths based on the above-mentioned settings. It is conceivable that the longer the fixed support 200, the more stable the supporting force it provides. In this embodiment, there are two fixed supports 200 with different lengths. The fixed support 200 closer to the center of gravity of the main control room 1 is longer, ensuring that the line connecting the centers of the two fixed supports 200 is greater than half the length of the first support member 2, thus placing the center of gravity of the main control room 1 above the two fixed supports 200.

[0054] The same applies to the sliding support 300, so it will not be elaborated here.

[0055] As one example, each first support member 2 is provided with 7 sets of first fixing holes 4, such as Figure 2 As shown, two sets of first fixing holes 4 are located at the first end of the first support member 2 (e.g., the left side of the main control room 1), another two sets of first fixing holes 4 are located at the second end of the first support member 2 (e.g., the right side of the main control room 1), and the remaining three sets are located in the middle of the first support member 2. Correspondingly, each fixed support 200 is provided with two sets of second fixing holes 5. With this arrangement, when the main control room 1 slides to the left, the two sets of first fixing holes 4 at the second end of the first support member 2 and the two sets of first fixing holes 4 in the middle can be aligned with a total of four sets of second fixing holes 5 on the two fixed supports 200, and then connected and fixed by fasteners; when the main control room 1 slides to the right, the two sets of first fixing holes 4 at the first end of the first support member 2 and the two sets of first fixing holes 4 in the middle can be aligned with a total of four sets of second fixing holes 5 on the two fixed supports 200, and then connected and fixed by fasteners. It can be imagined that when the main control room 1 slides to either side, its bottom has more than half of its area supported, which can ensure the overall stability of the main control room 1.

[0056] The method for determining whether the first fixing hole 4 and the second fixing hole 5 are aligned can be to measure the relative distance between the edge of one side of the main control room 1 and the towing mechanism to determine the initial position of the main control room 1. When it is moved to the required size, observe whether the first fixing hole 4 on the first support member 2 is aligned with the second fixing hole 5 of the fixed support 200.

[0057] For example, the second fixing hole 5 can be configured as a waist-shaped hole.

[0058] like Figure 6-8 As shown, the structure of the sliding support 300 and its cooperation with the second support member 3 will be described below.

[0059] The sliding support 300 includes a support body 301 and a guide rail component. The support body 301 is constructed of H-shaped steel. The guide rail component includes a first track structure 302 and a second track structure 303 fixed on the upper flange plate of the support body 301. The first track structure 302 and the second track structure 303 form a sliding limiting groove 304.

[0060] like Figure 7 As shown, the first track structure 302 and the second track structure 303 are arranged opposite to each other and symmetrical about the centerline of the sliding support 300. Specifically, the cross-sections of the first track structure 302 and the second track structure 303 are both right-angled polygonal shapes. The first end of the right-angled polygonal shape is welded to the support body 301, and the second end points to the other track structure. The two together form a receiving space for the lower flange plate of the second support member 3. The width of this receiving space is adapted to the width of the lower flange plate of the second support member 3 and is a clearance fit. Therefore, the lower flange plate of the second support member 3 can be translated along the length of the support member under the guidance of the sliding limiting groove 304, which restricts the sliding direction of the main control room 1 and prevents it from deviating.

[0061] Since the second support member 3 is made of H-beam, to further ensure reliable sliding, the sliding limiting groove 304 must also consider that the connection between the web of the second support member 3 and the lower flange plate should not hinder the sliding of the second support member 3. In this embodiment, a limiting hole 305 is formed between the second end of the first track structure 302 and the second end of the second track structure 303, and the width of the limiting hole 305 is adapted to the web of the second support member 3. When the width of the limiting hole 305 and the width of the web of the second support member 3 are in clearance fit, it can further limit the sliding direction and prevent the occurrence of displacement.

[0062] Based on this, the height of the sliding limit groove 304 is matched with the height of the lower flange of the second support member 3 to ensure that the main control room 1 will not shake during translation.

[0063] At least two sliding supports 300 are connected to the second support member 3. Each sliding support 300 has a third fixing hole 306 on its first track structure 302 and second track structure 303 for the anti-slip member 307 to pass through. The anti-slip member 307 restricts the sliding of the second support member 3. The anti-slip member 307 can be a screw. The third fixing hole 306 is a screw hole. When the screw is screwed into the screw hole, it presses against the lower flange of the second support member 3, which can fix the second support member 3 and prevent it from sliding unnecessarily. After the first support member 2 is fixedly connected to the fixed support 200, the position of the main control room 1 is further ensured.

[0064] like Figure 9-10 As shown, when the main control room 1 needs to be moved, the fasteners on the first support member 2 and the fixed support 200 below the main control room 1 are removed; the anti-slip member 307 on the sliding support 300 is loosened appropriately, allowing the second support member 3 to slide in the sliding limit groove 304 on the sliding support 300. The concave structure prevents the main control room 1 from tipping over during sliding. After sliding to the desired position, the fasteners on the first support member 2 and the fixed support 200 are installed and tightened, and the anti-slip member 307 on the sliding support 300 is pressed down to reliably fix the main control room 1. The above process enables the rapid and safe movement of the main control room 1, improves the construction efficiency of the tunnel boring machine, and ensures construction safety.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
