Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically to a tunnel support device. Background Technology

[0002] Tunnels are engineering structures buried underground, representing a form of human utilization of underground space. They are frequently involved in road and bridge construction. The advent of tunnel construction has played a significant role in the development of transportation engineering. Mountains that are otherwise inaccessible can be traversed more quickly and conveniently through tunnels, and rivers and seas that are otherwise impassable can be directly accessed via tunnels. During tunnel construction, to prevent collapse due to structural instability, support devices are used for reinforcement.

[0003] Existing tunnel collapse prevention support devices are mainly simple support structures, primarily constructed from steel bars or wood. While these structures are relatively simple and inexpensive, they cannot be adjusted according to the actual tunnel diameter. This results in a very narrow range of applications for these devices, limiting their flexibility in support work. Furthermore, since the typical tunnel curvature is meticulously designed, different tunnels may employ different inner wall curvatures. Consequently, the support points of existing devices cannot fit well against the tunnel's inner wall, affecting the support effect and creating certain safety hazards. Utility Model Content

[0004] To address the aforementioned technical problems, a tunnel support device is provided. This technical solution solves the problem that existing tunnel anti-collapse support devices, as mentioned in the background, are mainly simple support structures, primarily constructed from steel bars or wood. While these structures are relatively simple and inexpensive, they cannot adapt to changes in the support position based on the actual tunnel diameter during practical use. This results in a very narrow applicability range for such devices and an inflexible support function. Furthermore, since the general arc shape of tunnels is meticulously designed and studied, different tunnels may employ different inner wall curvatures. Consequently, the support points of existing support devices cannot fit well against the inner wall of the tunnel, affecting the support effect and creating certain safety hazards.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A tunnel support device includes a mounting plate, a support frame fixedly mounted at the bottom end of the mounting plate, a hydraulic rod provided at the top end of the mounting plate, and a support mechanism provided at the movable end of the hydraulic rod.

[0007] The support mechanism includes a mounting block, and a slider is movably mounted on the top of the mounting block via a connecting rod. The slider is slidably mounted on the outer surface of one side of the mounting frame. Two sets of fixing blocks are provided at the bottom of the front and rear ends of the mounting frame. A lead screw is rotatably mounted on the inner side of one set of fixing blocks, and a guide rod is provided on the inner side of the other set of fixing blocks.

[0008] Preferably, there are two sets of sliders, both sets of sliders are threadedly connected to the outer surface of the lead screw, and both sets of sliders are also slidably mounted on the outer surface of the guide rod.

[0009] Preferably, two sets of connecting rods are movably mounted at the bottom of both sets of sliders.

[0010] Preferably, the two sets of threads on the outer surface of the lead screw have opposite directions of rotation, and the output end of the motor is fixedly installed at one end of the lead screw.

[0011] Preferably, the mounting block is provided with the same support mechanism on both the left and right sides.

[0012] Preferably, the front side of the mounting plate is provided with several sets of warning lights.

[0013] Preferably, a support plate is fixedly installed at the top of the mounting bracket.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] First, by setting up hydraulic rods and support mechanisms, the support position of the support device can be flexibly adjusted. The movable end of the hydraulic rod is connected to the support mechanism, and the position of the support mechanism can be changed by adjusting the length of the hydraulic rod according to the actual tunnel diameter and needs, thus greatly expanding the applicability of the support device. Second, by driving the lead screw to rotate through the output end of the motor, two sets of sliders can move simultaneously in opposite or the same direction along the outer surface of the lead screw, realizing flexible adjustment of the support mechanism in the horizontal direction and ensuring that the support mechanism can fit tightly against the inner wall of the tunnel. In addition, the same support mechanism is set on both the left and right sides of the mounting block. Through the combined action of the support mechanisms on both sides, tunnel collapse accidents can be more effectively prevented, improving construction safety. Attached Figure Description

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] Reference Figure 1-4 As shown, the device includes a mounting plate 1, a hydraulic rod 4 at the top of the mounting plate 1, a support mechanism 5 at the movable end of the hydraulic rod 4, and a mounting block 501. A slider 503 is movably mounted on the top of the mounting block 501 via a connecting rod 502. There are two sets of sliders 503, and both sets of sliders 503 are threadedly connected to the outer surface of the lead screw 507. Two sets of connecting rods 502 are movably mounted on the bottom of both sets of sliders 503.

[0025] In this scheme, the mounting block 501 is movably connected to the slider 503 via the connecting rod 502, and both sets of sliders 503 are threadedly connected to the outer surface of the lead screw 507. The two sets of threads on the outer surface of the lead screw 507 rotate in opposite directions, so that when the output end of the motor 509 drives the lead screw 507 to rotate, the two sets of sliders 503 can move closer to each other or further away from each other at the same time, effectively enhancing the adjustment range of the support mechanism 5.

[0026] Reference Figure 1-4 As shown, two sets of sliders 503 are also slidably mounted on the outer surface of the guide rod 508. The sliders 503 are slidably mounted on one side of the outer surface of the mounting bracket 504. A support plate 505 is fixedly mounted on the top of the mounting bracket 504. Two sets of fixing blocks 506 are provided at the bottom of the front and rear ends of the mounting bracket 504. A lead screw 507 is rotatably mounted on the inner side of one set of fixing blocks 506. Two sets of threads on the outer surface of the lead screw 507 have opposite directions of rotation, and the output end of the motor 509 is fixedly mounted on one end of the lead screw 507. A guide rod 508 is provided on the inner side of the other set of fixing blocks 506. In this solution,

[0027] In this scheme, two sets of sliders 503 are slidably mounted on the outer surface of the guide rod 508. The guide rod 508 plays the role of guiding the sliders 503 to move linearly, ensuring the stability and accuracy of the sliders 503 during the movement. The sliders 503 are slidably mounted on one side of the outer surface of the mounting bracket 504, while the support plate 505 at the top of the mounting bracket 504 provides an additional support surface, further enhancing the structural strength of the entire support mechanism 5.

[0028] Reference Figure 1-3 As shown, the same support mechanism 5 is provided on both the left and right sides of the mounting block 501.

[0029] In this design, the same support mechanism 5 is provided on both the left and right sides of the mounting block 501, which improves the overall structural balance and allows the support mechanism 5 to distribute the load more evenly.

[0030] Reference Figure 1 As shown, several sets of warning lights 3 are provided on the front side of the mounting plate 1, and a support frame 2 is fixedly installed at the bottom of the mounting plate 1.

[0031] In this solution, the warning light 3 on the mounting plate 1 provides a clear visual warning during operation, enhancing safety performance. Secondly, the support frame 2 fixed at the bottom of the mounting plate 1 ensures the stability of the entire structure.

[0032] The working principle of this utility model is as follows: First, several sets of warning lights 3 are installed on the mounting plate 1. These warning lights 3 provide clear visual signals during operation, alerting operators to safety. Simultaneously, the support frame 2 fixed to the bottom of the mounting plate 1 ensures the stability of the entire device, preventing it from shaking or tipping over during operation. Second, the extension and retraction of the hydraulic rod 4 drives the support mechanism 5 to adjust up and down. The output end of the motor 509 drives the lead screw 507 to rotate. Because the two sets of threads on the outer surface of the lead screw 507 rotate in opposite directions, the two sets of sliders 503 connected to them can... Simultaneously moving towards the center or away from the outside, and guided by the guide rod 508, the stability of the slider 503's movement is ensured. The slider 503 is movably connected to the mounting block 501 via the connecting rod 502, allowing the mounting block 501 and other components on it to be adjusted. Furthermore, the support plate 505 at the top of the mounting frame 504 increases the support area, enhancing the strength and stability of the structure. Finally, the same support mechanism 5 is configured on both the left and right sides of the mounting block 501, improving the overall structural balance, distributing the load more evenly, and enhancing the load-bearing capacity of the support mechanism 5.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
