[0002] Tunnels are engineering structures buried in the earth's strata and are a form of human utilization of underground space. With the rapid development of the economy, highway and railway transportation have developed unprecedentedly. In order to shorten the distance and cross the terrain, various tunnels have been built in mountainous areas with complex terrain. However, during the tunnel construction process, tunnel support is required to prevent deformation or collapse of the surrounding rock.

[0003] Currently, the support structures used for tunnel inner walls generally have low stability. Although they can provide temporary support, they are still difficult to guarantee stability in the event of minor collapses. They are easily deformed by pressure, affecting the safety of use. Summary of the Invention

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0034] like Figure 1 As shown in this embodiment of the invention, a tunnel engineering support device includes: a support platform 1 and rollers 2 for controlling the movement of the support platform 1. The tunnel engineering support device further includes:

[0035] The support control component 3 is disposed on the support platform 1, and the support control component 3 is used to support the top and inner walls of the tunnel.

[0036] The compression positioning component 4 is disposed inside the support 1. The compression positioning component 4 is used to limit the position of the support control component 3 after the support control component 3 supports the inner walls on both sides of the tunnel.

[0037] When the tunnel engineering support equipment is in use, the support platform 1 is moved to the construction position by the roller 2. Then, the support control component 3 can support the inner wall of the tunnel top. Then, the compression positioning component 4 can be activated. The compression positioning component 4 will first drive the support control component 3 to support and fix the inner walls on both sides of the tunnel. After contacting the inner walls on both sides of the tunnel, it will limit the position of the support control component 3 to prevent the support control component 3 from shifting and improve the stability of the support.

[0038] like Figures 1 to 5 As shown, in this embodiment of the invention, the support control component 3 includes:

[0039] The main cylinder 31 is located inside the support 1, and the output end of the main cylinder 31 is located outside the support 1. The output end of the main cylinder 31 is connected to a rod 32, and a support plate 33 is installed at one end of the rod 32.

[0040] A side support assembly is disposed inside the support platform 1, and the side support assembly is used to support the inner walls on both sides of the tunnel.

[0041] like Figures 1 to 6 As shown, in this embodiment of the invention, the side support assembly includes:

[0042] A set of slots 34 are respectively opened on both sides of the support 1. Each set of slots 34 has a first auxiliary slot 35 and a second auxiliary slot 36 facing each other. The first auxiliary slot 35 and the second auxiliary slot 36 are respectively provided with a first auxiliary block 37 and a second auxiliary block 38.

[0043] Multiple sets of support structures are disposed inside the slot 34. The first auxiliary block 37 and the second auxiliary block 38 are respectively connected to different support structures. The support structures are used to support the tunnel inner walls with different curvatures.

[0044] like Figures 1 to 6As shown, in this embodiment of the invention, the support structure includes:

[0045] The slide plate 39 has a first sliding groove 310 and a second sliding groove 311 respectively on both sides, and a first sliding block 312 and a second sliding block 313 are respectively provided inside the first sliding groove 310 and the second sliding groove 311.

[0046] The first sliding block 312 is slidably connected to the second sliding groove 311 on the adjacent slide plate 39, and the second sliding block 313 is slidably connected to the first sliding groove 310 on the adjacent slide plate 39.

[0047] like Figures 1 to 5 As shown, in this embodiment of the invention, the extrusion positioning component 4 includes:

[0048] Motor 41 is rotatably connected to one side of the second auxiliary slot 36. The output end of motor 41 is connected to screw 42, and screw 42 is threadedly connected to the second auxiliary block 38.

[0049] A rotating rod 43 is installed on one side of the motor 41. A first bevel gear 44 and a second bevel gear 45 are rotatably connected inside the support 1. The first bevel gear 44 and the second bevel gear 45 mesh with each other. A first transmission belt 46 is sleeved between the first bevel gear 44 and the rotating rod 43.

[0050] A groove 47 is formed on the inner wall of the slot 34. A positioning rod 48 is provided inside the groove 47. A threaded column 49 is slidably connected to the positioning rod 48. A pressing plate 412 is provided on one side of the threaded column 49. A threaded collar 410 is also rotatably provided on the groove 47. The threaded collar 410 is threadedly engaged with the threaded column 49. A second transmission belt 411 is sleeved between the threaded collar 410 and the second bevel gear 45.

[0051] In this embodiment of the invention, the resistance that the motor 41 needs to overcome to rotate itself is greater than the resistance that the motor 41 needs to overcome to drive the screw 42 to rotate.

[0052] like Figure 1 As shown, in this embodiment of the invention, an electrically controlled cylinder 5 is provided on one side of the support 1, and the roller 2 is installed at one end of the electrically controlled cylinder 5.

[0053] When in use, first start the main cylinder 31, which will push the air rod 32 upward, thereby causing the support plate 33 to move upward until it contacts the inner wall of the tunnel top, thus achieving the support effect.

[0054] Then, the motor 41 is started. Since the resistance that the motor 41 needs to overcome to rotate itself is greater than the resistance that the motor 41 needs to overcome to drive the screw 42 to rotate, the operation of the motor 41 will first drive the screw 42 to rotate, pushing the second auxiliary block 38 to move outward, and then driving all the support structures to move outward. Then, the sliding plates 39 from top to bottom will contact the inner walls of both sides of the tunnel one by one. The first sliding block 312, the second sliding block 313, the first sliding groove 310, and the second sliding groove 311 can ensure the stability of the sliding plate 39 during the movement. After the bottom sliding plate 39 contacts the inner wall of the tunnel, the support effect on the inner wall of the tunnel is achieved.

[0055] Subsequently, since the bottom slide plate 39 cannot move, the second auxiliary block 38 will also be unable to move, and the guide screw 42 will not be able to rotate. At this time, the operation of the motor 41 will drive it to start rotating, and transmit the rotation to the first bevel gear 44 through the first transmission belt 46. The first bevel gear 44 will drive the second bevel gear 45 to rotate. The second bevel gear 45 will drive the threaded collars 410 on both sides to rotate through the second transmission belts 411 on both sides. The threaded engagement between the threaded collars 410 and the threaded column 49 is used to control the movement of the threaded column 49, so that the extrusion plate 412 contacts the slide plate 39 and extrudes the slide plate 39, thereby limiting the operation of the slide plate 39 and preventing the slide plate 39 from resetting.

[0056] In summary, when using the tunnel engineering support equipment, the support platform 1 is moved to the construction position by the roller 2, and then the support control component 3 can support the inner wall of the tunnel top. Then, the compression positioning component 4 can be activated. The compression positioning component 4 will first drive the support control component 3 to support and fix the inner walls on both sides of the tunnel. After contacting the inner walls on both sides of the tunnel, it will limit the position of the support control component 3 to prevent the support control component 3 from shifting and improve the stability of the support.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
