Figure 3 is a schematic diagram of the structure of the adjustment mechanism in the first embodiment, Figure 4 yes Figure 3 The enlarged view of the local structure at B, Figure 5 It is a schematic diagram of the disassembled structure of the pipeline support pipe in the first embodiment.

[0032] The present invention provides a pipeline reinforcement structure for tunnels under road bridges: comprising a base plate 101, two pipeline support tubes 102 and four adjustment mechanisms, each of the adjustment mechanisms comprising a mounting rail 103, a positive and negative threaded rod group, two sliding seats 104 and two connectors 105, each of the positive and negative threaded rod group comprising a bidirectional drive motor 106, a first threaded rod 107, a second threaded rod 108 and two ball screw nut pairs 109, and each of the pipeline support tubes 102 comprising a first tube body 110 and a second tube body 111. The above-mentioned scheme solves the problem that the triangular support block in the existing pipeline reinforcement structure for tunnels under municipal road bridges is fixedly arranged on the side of the support tube, the position of the triangular support block cannot be adjusted, and the fixing effect is not ideal when a longer support tube is fixed by the triangular support block. It can be understood that the above-mentioned scheme can be used in the structure of the pipeline reinforcement component for tunnels under municipal road bridges.

[0033] According to this specific embodiment, two pipeline support pipes 102 are arranged in parallel on the base plate 101, and a connecting column 112 is fixedly arranged between the two pipeline support pipes 102. Two fixing parts 113 are arranged on both sides of each pipeline support pipe 102. The pipeline support pipe 102 is fixed to the base plate 101 by the fixing parts 113, and the pipeline passing through the tunnel under the road bridge is supported by the pipeline support pipe 102. The setting of the connecting column 112 makes the overall structure of the entire reinforced structure more solid.

[0034] Wherein, the side of each pipeline support tube 102 is provided with the adjustment mechanism, four first T-slots 114 are provided on the base plate 101, and the first T-slots 114 are located on the side of the corresponding pipeline support tube 102, and second T-slots 115 are provided on both sides of the top of each pipeline support tube 102, one end of the fixing member 113 is slidably connected to the first T-slot 114, and the other end of the fixing member 113 is slidably connected to the second T-slot 115, and the mounting rail 103 is fixedly installed on the base plate 101 and is located on the side of the corresponding pipeline support tube 102, and the positive and negative threaded rod group is arranged inside the mounting rail 103, and two sliding seats 104 are slidably arranged on the mounting rail 103, and the two output ends of the positive and negative threaded rod group are respectively connected to the two sliding seats 104, and each The connecting piece 105 is installed on each sliding seat 104, and each connecting piece 105 is connected to the corresponding fixing piece 113. When the pipeline support tubes 102 of different lengths are used to support the pipeline, the forward and reverse screw groups are started to drive the corresponding two sliding seats 104 to slide toward or away from each other on the mounting guide rail 103, so as to adjust the positions of the two sliding seats 104 on the mounting guide rail 103. Since the connecting piece 105 arranged on the sliding seat 104 is connected to the fixing piece 113, the two fixing pieces 113 are adjusted to the appropriate position to complete the fixation of the pipeline support tube 102. With the above structure, the position of the fixing piece 113 is adjusted by setting the adjusting mechanism, so that when the fixing piece 113 is used to fix the pipeline support tubes 102 of different lengths, the fixing effect is better.

[0035] Secondly, the bidirectional drive motor 106 is installed in the middle of the mounting guide rail 103, and the two output ends of the bidirectional drive motor 106 are respectively provided with the first threaded rod 107 and the second threaded rod 108, the first threaded rod 107 and the second threaded rod 108 have opposite spirals, and the first threaded rod 107 and the second threaded rod 108 are both provided with the ball screw nut pair 109, and the ball screw nut pair 109 is connected to the corresponding sliding seat 104, and the bidirectional drive motor 106 is started to drive the first threaded rod 107 and the second threaded rod 108 to rotate synchronously. Since the ball screw nut pair 109 is connected to the sliding seat 104, and the thread on the first threaded rod 107 is opposite to the thread on the second threaded rod 108, the two sliding seats 104 move toward or away from each other on the mounting guide rail 103.

[0036] At the same time, the first tube body 110 and the second tube body 111 are both arranged in an inverted U-shaped structure, and the first tube body 110 and the second tube body 111 are fixed by a connecting mechanism. Each of the pipeline support tubes 102 is composed of the first tube body 110 and the second tube body 111, and the connection between the first tube body 110 and the second tube body 111 is completed by the setting of the connecting mechanism.

[0037] In addition, each of the connecting mechanisms includes an external fixing component 116 and an internal fixing component 117. The first tube body 110 and the corresponding second tube body 111 are connected via the external fixing component 116 and the internal fixing component 117. The connection between the first tube body 110 and the second tube body 111 is completed by the cooperation of the external fixing component 116 and the internal fixing component 117. Here, the external fixing component 116 and the internal fixing component 117 are both existing technologies and are not described in detail.

[0038] In addition, each of the sliding seats 104 is provided with sliding feet 118 on both sides, and each of the mounting rails 103 is provided with sliding grooves 119 on both sides.

[0039] When using a road bridge under-tunnel pipeline reinforcement structure of this embodiment, the pipeline support pipe 102 is fixed to the base plate 101 by the fixing member 113, and the pipeline under the road bridge under-tunnel is supported by the pipeline support pipe 102. The overall structure of the reinforcement structure is more solid by the setting of the connecting column 112, and when the pipeline support pipe 102 of different lengths is used to support the pipeline, the positive and negative threaded screw group is started to drive the corresponding two sliding seats 104 on the mounting guide rail 103. The two sliding seats 104 can slide toward or away from each other, thereby adjusting the positions of the two sliding seats 104 on the mounting guide rail 103. Since the connecting member 105 arranged on the sliding seat 104 is connected to the fixing member 113, the two fixing members 113 are adjusted to the suitable position to complete the fixation of the pipeline support tube 102. With the above structure, the position of the fixing member 113 can be adjusted through the setting of the adjusting mechanism, so that when the fixing member 113 is used to fix the pipeline support tubes 102 of different lengths, the fixing effect is better.

[0042] The present invention provides a road bridge under-tunnel pipeline reinforcement structure which also includes a plurality of auxiliary support members 201 .

[0043] According to this specific embodiment, each of the first threaded rods 107 and each of the second threaded rods 108 is provided with the auxiliary support member 201 at one end away from the corresponding bidirectional drive motor 106, one end of the auxiliary support member 201 is fixed inside the mounting guide rail 103, and the other end of the auxiliary support member 201 is arranged on the outside of the corresponding first threaded rod 107 and the second threaded rod 108. The auxiliary support member 201 is used to auxiliary support the first threaded rod 107 and the second threaded rod 108, so that the structure of the first threaded rod 107 and the second threaded rod 108 is more stable when the first threaded rod 107 and the second threaded rod 108 rotate.

[0044] Among them, each of the auxiliary support members 201 is provided with a rotating bearing 202, and each of the first threaded rod 107 and the corresponding second threaded rod 108 is provided with a rotating head 203 at one end away from the corresponding bidirectional drive motor 106, and the rotating head 203 is embedded in the corresponding rotating bearing 202. Through the setting of the rotating bearing 202 and the rotating head 203, the ends of the first threaded rod 107 and the second threaded rod 108 rotate more smoothly when they rotate on the auxiliary support member 201.

[0045] Secondly, each of the sliding seats 104 is provided with a through groove 204, and each of the through grooves 204 is provided with a protective plate 205. The end of the protective plate 205 is connected to the side of the end of the corresponding mounting guide rail 103. Through the setting of the protective plate 205, the end face of the mounting guide rail 103 is protected to prevent the external environment from affecting the operation of the positive and negative screw rod group.

[0046] At the same time, fixing blocks 206 are provided on both sides of the end of each protective plate 205, and the fixing blocks 206 are connected to the side surfaces of the corresponding end of the mounting rail 103. The installation of the protective plate 205 is completed by the setting of the fixing blocks 206.

[0047] When using a pipeline reinforcement structure for a road bridge under a tunnel of this embodiment, the auxiliary support member 201 is used to auxiliary support the first threaded rod 107 and the second threaded rod 108, so that the structure of the first threaded rod 107 and the second threaded rod 108 is more stable when they rotate, and the setting of the rotating bearing 202 and the rotating head 203 makes the ends of the first threaded rod 107 and the second threaded rod 108 rotate more smoothly when they rotate on the auxiliary support member 201, and the setting of the protective plate 205 protects the end face of the mounting guide rail 103 to prevent the external environment from affecting the operation of the positive and negative thread rod group.

[0048] The working / implementation / use principle of the present invention is: the pipeline support pipe 102 is fixed to the base plate 101 by the fixing piece 113, and the pipeline passing through the tunnel under the road bridge is supported by the pipeline support pipe 102. The overall structure of the entire reinforcement structure is more solid by the arrangement of the connecting column 112. When the pipeline support pipes 102 of different lengths are used to support the pipeline, the positive and negative threaded screw groups are started to drive the corresponding two sliding seats 104 to slide toward or away from each other on the mounting rail 103, thereby adjusting the positions of the two sliding seats 104 on the mounting rail 103. Since the connecting piece 105 arranged on the sliding seat 104 is connected to the fixing piece 113, By adjusting the two fixing members 113 to the suitable position, the pipeline support tube 102 is fixed. The above structure is adopted and the position of the fixing member 113 is adjusted through the setting of the adjustment mechanism, so that when the fixing member 113 is used to fix the pipeline support tubes 102 of different lengths, the fixing effect is better, and the auxiliary support member 201 is used to auxiliary support the first threaded rod 107 and the second threaded rod 108, so that the first threaded rod 107 and the second threaded rod 108 have a more stable structure when rotating. Through the setting of the protective plate 205, the end face of the mounting guide rail 103 is protected to prevent the external environment from affecting the operation of the positive and negative thread rod group.
