Abstract
Description
Technical Field
[0001] This utility model relates to the field of tunnel construction, and in particular to a TBM lane anti-collision device. Background Technology
[0002] TBM, or Tunnel Boring Machine, is a high-efficiency tunneling machine used in tunnel construction projects such as long-distance water diversion projects. During TBM tunneling, heavy-duty transport vehicles continuously deliver materials such as tunnel segments, gravel, and cement mortar into the tunnel. Frequent passage of heavy-duty vehicles easily leads to collisions, affecting construction safety and efficiency. Especially in downhill sections of TBM tunneling, the frequent transport of materials by heavy-duty vehicles in the roadway poses a significant safety hazard. If out of control, it can cause serious accidents to workers ahead of the TBM and to the TBM itself, with extremely severe consequences. Therefore, installing a final safety device in the TBM roadway to ensure the safety of construction personnel and equipment is crucial.
[0003] The common anti-rollover device for TBM material transport vehicles is called a wheel stop, which typically uses triangular wooden blocks or parking wedges. These are placed behind the wheels when the vehicle is stationary to prevent them from rolling. This device is simple in structure and easy to use, but it can only be used when the vehicle is stationary and cannot be used in emergency situations where the vehicle is out of control. Lane safety barriers, on the other hand, provide collision protection and cushioning for moving vehicles. Existing lane safety barriers are usually made of traditional welded steel. While the welding method is simple, most have structural design flaws, resulting in low energy absorption efficiency. They are prone to damaging vehicles upon collision, cannot effectively absorb kinetic energy, and require replacement if the lane safety barrier beam is damaged, affecting material transport and severely impacting project progress.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0006] A TBM lane collision avoidance device, characterized in that it comprises:
[0007] The first and second supports, arranged at intervals on the left and right, are both used for installation on the trailer attached to the TBM.
[0008] The protective frame has one end that can rotate laterally and is connected to the first support, and the back of the other end abuts against the second support; the upper and lower parts of the front of the protective frame are respectively detachably provided with a number of composite anti-collision buffer strips, and the middle part of the front of the protective frame is detachably provided with a number of composite rubber spring buffer blocks.
[0009] Preferably, the composite anti-collision buffer strip includes a first spring and an arc-shaped metal strip, the two ends of which are detachably fixed to the protective frame, and the first spring is located between the back of the middle part of the metal strip and the front of the protective frame.
[0010] Preferably, the composite rubber spring buffer block includes a rubber block, a second spring, and a base. The second spring is embedded in the rubber block, the rubber block is fixed on the base, and the base is detachably mounted on the protective frame.
[0011] Preferably, the composite rubber spring buffer blocks are multiple and distributed at intervals along the left-right direction.
[0012] Preferably, the upper and lower parts of the protective frame are provided with a plurality of composite anti-collision buffer strips, and the composite anti-collision buffer strips are arranged at intervals along the left and right directions.
[0013] Preferably, the height of the composite rubber spring buffer block protruding from the front of the protective frame is greater than the height of the composite anti-collision buffer strip protruding from the front of the protective frame.
[0014] Preferably, the protective frame includes two horizontal beams arranged at intervals and multiple vertical beams located between the two horizontal beams and connecting the two horizontal beams. Each of the vertical beams is arranged at intervals in the left-right direction. The composite anti-collision buffer strip is disposed on the two horizontal beams, and the composite rubber spring buffer block is disposed on the vertical beam.
[0015] Preferably, a rubber buffer pad is provided on the front of the second support, and the protective frame abuts against the rubber buffer pad.
[0016] Preferably, the protective frame is detachably mounted on the first support.
[0017] Preferably, the protective frame is rotatably connected to the first support via a self-lubricating bearing.
[0018] The beneficial effects of this utility model are as follows: This utility model can be installed on the trailer attached to the TBM using the first and second supports. In use, the protective frame can be rotated to abut against the second support. When a collision occurs due to vehicle slippage or other reasons, the composite anti-collision buffer strip and composite rubber spring buffer block can absorb energy and buffer against the collision with the vehicle, effectively improving the buffering performance and preventing injury to the TBM head and workers. Furthermore, since the composite anti-collision buffer strip and composite rubber spring buffer block are detachable and mounted on the protective frame, they can be directly and quickly replaced after being damaged in a collision without replacing the entire TBM lane anti-collision device. This effectively shortens the replacement period, reduces the impact on the construction progress, and facilitates maintenance. Moreover, when not in use, the protective frame can be rotated around the first support to avoid personnel or equipment, further facilitating its use. Attached Figure Description

[0026] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0028] Reference Figures 1 to 4 A preferred embodiment of this utility model discloses a TBM lane collision avoidance device, characterized in that it includes: a first support 11 and a second support 12 arranged at intervals on the left and right sides, both for installation on the rear trailer of the TBM; a protective frame 20, one end of which is rotatably connected to the first support 11, and the back of the other end abutting against the second support 12; a plurality of composite anti-collision buffer strips 30 are detachably provided on the upper and lower parts of the front of the protective frame 20, and a plurality of composite rubber spring buffer blocks 40 are detachably provided on the middle part of the front of the protective frame 20. This utility model can be installed on the trailer attached to the TBM via the first support 11 and the second support 12. In use, the protective frame 20 can be rotated to abut against the second support 12. When a collision occurs due to vehicle slippage or other reasons, the composite anti-collision buffer strip 30 and the composite rubber spring buffer block 40 can absorb energy and buffer against the collision with the vehicle, effectively improving the buffering performance and preventing injury to the TBM head and workers. Furthermore, since the composite anti-collision buffer strip 30 and the composite rubber spring buffer block 40 are detachable and mounted on the protective frame 20, they can be directly and quickly replaced after being damaged in a collision without replacing the entire TBM lane anti-collision device, effectively shortening the replacement period, reducing the impact on the construction progress, and facilitating maintenance. Moreover, when not in use, the protective frame 20 can be rotated around the first support 11 to avoid personnel or equipment, effectively facilitating use.
[0029] As a preferred embodiment of this utility model, it may also have the following additional technical features:
[0030] In this embodiment, the composite anti-collision buffer strip 30 includes a first spring 31 and an arc-shaped metal strip 32. The two ends of the metal strip 32 are detachably fixed to the protective frame 20. The first spring 31 is located between the back of the middle portion of the metal strip 32 and the front of the protective frame 20, providing excellent energy absorption and effectively improving the buffering effect. It is also easy to manufacture. In other embodiments, the composite anti-collision buffer strip 30 can also adopt other commonly used composite buffer structures. For example, the first spring 31 can be replaced with a rubber pad or other commonly used buffer structures, or the metal strip 32 can be made of other suitable materials or replaced with movable parts. In this embodiment, the metal strip 32 is made of high-strength metal, preferably steel, and the first spring 31 is also a high-strength spring to meet the energy absorption needs of heavy-duty vehicle collisions.
[0031] In this embodiment, the composite rubber spring buffer block 40 includes a rubber block 41, a second spring 42, and a base 43. The second spring 42 is embedded within the rubber block 41, and the rubber block 41 is fixed to the base 43. The base 43 is detachably mounted on the protective frame 20. The structure is simple and reliable, convenient for processing, manufacturing, and assembly, and has excellent energy absorption performance. In other embodiments, the composite rubber spring buffer block 40 may also employ other suitable composite structures including springs and rubber, and is not limited to this. In this embodiment, the rubber block 41 is cylindrical, easily adapting to the shape of the second spring 42, resulting in more even force distribution. The second spring 42 also uses a high-strength spring, capable of meeting the energy absorption needs of heavy-duty vehicle collisions.
[0032] In this embodiment, both ends of the metal strip 32 of the composite anti-collision buffer strip 30 are detachably fixed to the protective frame 20 by two screws, and the base 43 of the composite rubber spring buffer block 40 is also detachably fixed to the protective frame 20 by multiple screws. The structure is simple, the connection is firm, and it is convenient to assemble and disassemble. In other embodiments, the composite anti-collision buffer strip 30 and the composite rubber spring buffer block 40 can also be detachably installed on the protective frame 20 by other commonly used connection structures such as bolt assemblies, rivet assemblies, buckles, and clips, and are not limited to these.
[0033] In this embodiment, there are multiple composite rubber spring buffer blocks 40 and they are distributed at intervals along the left and right directions. This ensures that the composite rubber spring buffer blocks 40 can contact the colliding vehicle when a collision occurs, and also improves the energy absorption effect.
[0034] In this embodiment, multiple composite anti-collision buffer strips 30 are provided on both the upper and lower parts of the protective frame 20, and each composite anti-collision buffer strip 30 is arranged at intervals along the left and right directions. This can also ensure that the composite anti-collision buffer strips 30 can contact the colliding vehicle when a collision occurs, and can also improve the energy absorption effect.
[0035] In this embodiment, the height of the composite rubber spring buffer block 40 protruding from the front of the protective frame 20 is greater than the height of the composite anti-collision buffer strip 30 protruding from the front of the protective frame. This ensures that in the event of a collision, the composite rubber spring buffer block 40 can make contact with the colliding vehicle first, reducing damage to the vehicle. In the event of a more severe collision, the composite anti-collision buffer strip 30 then makes contact with the colliding vehicle, ensuring the safety of the TBM equipment.
[0036] In this embodiment, the protective frame 20 includes two horizontal beams 21 arranged vertically at intervals and multiple vertical beams 22 located between and connecting the two horizontal beams 21. The vertical beams 22 are arranged at intervals in the left-right direction. Composite anti-collision buffer strips 30 are disposed on the two horizontal beams 21, and composite rubber spring buffer blocks 40 are disposed on the vertical beams 22. The structure is simple, robust, and easy to manufacture. In this embodiment, the two horizontal beams 21 are hollow beams, and both the horizontal beams 21 and the vertical beams 22 are made of high-strength metal, which can reduce weight to a certain extent while ensuring structural strength. The horizontal beams 21 and vertical beams 22 are preferably made of high-strength steel and are fixed together by welding; however, other suitable materials and connection methods can also be used.
[0037] In this embodiment, a rubber buffer pad is provided on the front of the second support 12, and the protective frame 20 abuts against the rubber buffer pad, which can reduce the impact damage between the second support 12 and the protective frame 20 during use, and also help to further improve the buffer energy absorption effect and ensure construction safety.
[0038] In this embodiment, the protective frame 20 is detachably mounted on the first support 11 for easy disassembly and maintenance. In this embodiment, the protective frame 20 is rotatably connected to the first support 11 via a self-lubricating bearing 13, facilitating the unfolding and retraction of the protective frame 20 and simplifying maintenance. In application, the protective frame 20 can be detachably mounted on the first support 11 using common detachable structures such as bolt assemblies or retaining rings; those skilled in the art can choose flexibly. In this embodiment, both the first support 11 and the second support 12 are made of high-strength metal, which helps to improve structural strength.
[0039] Without causing conflict, those skilled in the art can freely combine and use the above-mentioned additional technical features.
[0040] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
