[0002] The pipe segment is the main assembly component in tunnel construction and the innermost barrier of the tunnel. It is responsible for resisting soil pressure, groundwater pressure and some special loads. The quality of the pipe segment is directly related to the overall quality and safety of the tunnel, and affects the tunnel's waterproof performance and durability.

[0003] Segment transporters are specialized vehicles used to transport segments during tunnel construction. In recent years, with the increasing demand for road and railway construction, and the increasing number of tunnels being built, the demand for segment transporters has also increased. To save costs, segment transporters are now being replaced by road vehicles rather than rail vehicles. Road transporters have the advantages of not requiring track, resulting in low engineering costs and a short lead time. However, their disadvantage is that alignment between the transporter and the spreader is difficult. Since the spreader has very little left-right adjustment, the positioning of the segment transporter is highly critical. The limited space within tunnels makes adjusting the vehicle difficult, which inevitably affects work efficiency. Summary of the Invention

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] Example 1:

[0041] like Figure 1 、 2 The segment bracket shown in the figure comprises a base 1, a bracket body 2, and a driving component 3. Each component is described in detail below.

[0042] Base 1 Figure 1 In the longitudinal direction, Figure 2 The middle is its width direction. In this embodiment, a groove 10 is provided on the base 1 , and the extending direction of the groove 10 is its length direction.

[0043] The bracket body 2 is disposed on the base 1 and can slide relative to the base 1 or be fixed to the base 1. Specifically, the bracket body 2 is disposed in a groove 10. The groove 10 has a structure with high sides and a low middle, which can limit the sliding direction of the bracket body 2, so that the bracket body 2 can only slide in the longitudinal direction of the base 1, preventing the bracket body 2 from sliding out of the base 1.

[0044] In this embodiment, the bracket body 2 further includes a bracket base 20, a bracket support 21, and a bracket seat 22. The bracket base 20 is located in the groove 10, and preferably, the height of the bracket base 20 does not protrude from the groove 10; the bracket support 21 is connected to the bracket base 20.

[0045] The bracket 22 is connected to the bracket support 21. The bracket 22 adopts a hollow frame structure, which can reduce the weight of the bracket body 2. The bracket 22 is used to support the pipe segment. For this purpose, the bracket 22 has a supporting surface 220 that matches the shape of the pipe segment, which is arc-shaped in the figure. The pipe segment is supported on the supporting surface 220, and the support is more stable, and the pipe segment will not shake. In addition, there are multiple brackets 22 along the sliding direction of the bracket body 2, such as two, three, four, etc., to achieve stable support for the pipe segment.

[0046] The driving component 3 is arranged on the base 1 and connected to the bracket body 2, and is used to drive the bracket body 2 to slide on the base 1. Figure 1 In this embodiment, the driving component 3 is a hydraulic cylinder, and a balancing valve is provided on the hydraulic cylinder. The cylinder seat 30 of the hydraulic cylinder is fixed to the base 1, and the cylinder piston 31 of the hydraulic cylinder is fixed to the bracket body 2. The adjustment position of the bracket body 2 is adjusted by controlling the extension and contraction of the hydraulic cylinder.

[0047] In a preferred embodiment of this embodiment, the bracket further includes a sliding member 4, which is disposed on the base 1. Specifically, the sliding member 4 is also disposed within the groove 10. The bracket body 2 is disposed on the sliding member 4. The sliding member 4 is used to reduce the sliding resistance of the bracket body 2. In this embodiment, the sliding member 4 is a slide plate, and therefore, the material of the slide plate 4 is selected to have a low coefficient of friction. Of course, the sliding member 4 may also be other structures such as a sliding guide rail.

[0048] In a preferred implementation of this embodiment: the bracket also includes a pressure plate 5, which is connected to the base 1, and part of the pressure plate 5 extends above the groove 10 to limit the bracket bottom plate 20 from escaping from the groove 10. In the figure, the pressure plates 5 are connected on both sides of the groove 10.

[0049] The entire segment bracket can be removed and installed when needed. The installation steps are as follows:

[0050] Fix the sliding member 4 in the groove 10 of the base 1 with bolts; fix the cylinder seat 30 to the base 1 with bolts; place the bracket body 2 on the sliding member 4 and fix the bracket body 2 to the base 1 with bolts; fix the cylinder piston 31 of the hydraulic cylinder to the bracket body 2 with bolts; fix the pressure plate 5 to the base 1 with bolts; connect the hydraulic system pipeline.

[0051] Example 2:

[0052] like Figure 3The pipe segment transport vehicle shown includes a vehicle body 60, a first bracket 61, and a second bracket 62. The pipe segments are supported on the first bracket 61 and the second bracket 62 at the same time. The first bracket 61 and the second bracket 62 adopt the pipe segment bracket in Example 1. The bases 1 of the first bracket 61 and the second bracket 62 are both fixed on the vehicle body 60, and the arc-shaped supporting surfaces 220 of the brackets 22 of the first bracket 61 and the second bracket 62 are arranged relative to each other.

[0053] When the segment transport vehicle is in the transport state: the bracket body 2 is fixed to the base 1, such as by fasteners such as bolts; when the segment transport vehicle is in the segment position adjustment state: the driving component 3 drives the bracket body 2 to slide on the base 1 to adjust the position.

[0054] The following describes the steps for using this embodiment:

[0055] Place the two sets of prepared segment brackets symmetrically on the corresponding positions of the segment transport vehicle, and fix the base 1 to the vehicle body 60 with bolts; place the segments on the first bracket 61 and the second bracket 62, and try to place them in the center left and right; drive the segment transport vehicle into the tunnel and drive the segments under the hoist; observe the deviation distance between the segment center and the hoist center, and adjust the segment position if it exceeds the hoist safety distance; remove the bolts on the bracket body 2 to release the bracket body 2 from the base 1; use the hydraulic system to control the extension and contraction of the hydraulic cylinder to push the bracket body 2 to move so that the segment center coincides with the hoist center; use the hoist to lift the segment away; use the hydraulic system to control the extension and contraction of the hydraulic cylinder to push the bracket body 2 to the initial position; use bolts to fix the bracket body 2 to the base 1 again, and prepare for the next transportation.
