Description

Technical Field

[0001] This utility model relates to a layout template for tunnel construction, specifically a rapid layout template suitable for tunnel perimeter openings, belonging to the field of tunnel construction technology. Background Technology

[0002] In tunnel blasting, the role of peripheral holes is to blast out a relatively flat tunnel cross-section outline. Peripheral holes are arranged around the tunnel perimeter and usually employ smooth blasting techniques to reduce disturbance to the surrounding rock and maintain its original bearing capacity. The accurate layout of peripheral holes is of vital importance to the tunnel forming quality, over-excavation and under-excavation control, and construction safety.

[0003] However, traditional layout methods usually involve manually using measuring instruments to lay out the perimeter eye positions point by point. This is not only time-consuming, but also easily affected by human factors, such as measurement errors and inaccurate markings. It has problems such as cumbersome operation, low efficiency, and difficulty in guaranteeing accuracy.

[0004] To address these issues, we provide a rapid layout template suitable for tunnel perimeter eyes. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a rapid layout template suitable for tunnel perimeter openings, with the specific technical solution as follows:

[0006] A rapid layout template suitable for tunnel perimeter eyes includes a support frame. Multiple positioning marker modules are connected within the support frame. Each positioning marker module includes a fixed block. A first push cylinder is connected to the side end of the fixed block. A lateral moving block is connected to the driving end of the first push cylinder. A second push cylinder is connected to the upper end of the lateral moving block. A vertical moving block is connected to the driving end of the second push cylinder. A laser pointer is connected within the vertical moving block. A lateral ranging mechanism is connected between the fixed block and the lateral moving block. A vertical ranging mechanism is connected between the lateral moving block and the vertical moving block. An intelligent control box is connected to the lower end of the support frame.

[0007] Preferably, the support frame is made of a corrosion-resistant, high-strength, lightweight alloy material, and the support frame has an arc-shaped structure similar to the cross-section of a tunnel. The positioning mark modules are evenly distributed within the support frame.

[0008] Preferably, the intelligent control box is connected to all the positioning marker modules via wires.

[0009] Preferably, the fixing block is connected within the support frame, the first push cylinder is horizontally positioned, the second push cylinder is vertically positioned, and the laser pointer is capable of illuminating a non-divergent laser beam.

[0010] Preferably, the horizontal ranging mechanism has the same structure as the vertical ranging mechanism. Taking the horizontal ranging mechanism as an example, it includes: a sleeve, a support rod inserted into the sleeve, and a ranging pen connected to the side end of the support rod.

[0011] Preferably, a support frame is connected to the side end of the vertical moving block, and a protective cover is rotatably connected to the side end of the support frame. The protective cover is located at the emitting head of the laser pointer. A third push cylinder is rotatably connected to the upper end of the vertical moving block, and the driving end of the third push cylinder is rotatably connected to the protective cover.

[0012] Preferably, a fourth push cylinder is connected to the lower end of the support frame, a movable base is connected to the lower end of the fourth push cylinder, a roller is provided at the lower end of the movable base, a fifth push cylinder is connected to the side end of the movable base, and a fixed toothed plate is connected to the driving end of the fifth push cylinder.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This rapid layout formwork for tunnel perimeter holes is equipped with a positioning mark module, which can mark and locate the drilling positions of perimeter holes. It can locate all perimeter hole positions at once. Specifically, by controlling one positioning mark module, its internal laser pointer illuminates the positioning laser at the determined drilling position of a perimeter hole. Then, the remaining positioning mark modules will automatically adjust their positions according to the construction drilling drawings. Each positioning mark module corresponds to a drilling point, thus marking and locating the drilling positions of all perimeter holes. Its operation is simple and highly automated, and it can quickly locate the positions of all perimeter holes, greatly improving construction efficiency. Moreover, the device automatically positions itself according to the construction drawings, and its positioning accuracy is high, which can effectively reduce the errors caused by manual positioning.

[0015] 2. This rapid layout template for tunnel perimeter eyes is equipped with a horizontal distance measuring mechanism and a vertical distance measuring mechanism, which correspond to the horizontal and vertical movement of the laser pointer, respectively. The laser pointer moves inside the sleeve, and its measuring laser is not interfered with by external dust. In this way, the movement of the laser pointer can be accurately measured, which facilitates precise adjustment of the movement of the laser pointer.

[0016] 3. This rapid layout template for tunnel perimeter holes is equipped with a protective cover. When drilling is completed and blasting is required, the third pusher cylinder is activated, which will drive the protective cover to rotate, thereby covering the front end of the laser pointer's transmitter head. This prevents dust generated by the explosion from contaminating or damaging the laser pointer's transmitter head, thus extending its service life. Attached Figure Description

[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] Please see Figure 1 — Figure 5 The system includes a support frame 1, which is made of corrosion-resistant, high-strength, lightweight alloy material to ensure its structural strength and service life. The support frame 1 is an arc-shaped structure similar to the tunnel cross-section. Multiple positioning marker modules 2 are connected inside the support frame 1. The positioning marker modules 2 are evenly distributed inside the support frame 1, and each positioning marker module 2 corresponds to a peripheral eye. An intelligent control box 11 is connected to the lower end of the support frame 1. The intelligent control box 11 is connected to all the positioning marker modules 2 through wires. The intelligent control box 11 adjusts each positioning marker module 2 according to the construction drawings.

[0025] A fourth push cylinder 15 is connected to the lower end of the support frame 1. The fourth push cylinder 15 is used to adjust the height of the support frame 1. A movable base 16 is connected to the lower end of the fourth push cylinder 15. The movable base 16 is equipped with rollers at the lower end to facilitate the movement of the device. A fifth push cylinder 17 is connected to the side end of the movable base 16. A fixed toothed plate 18 is connected to the driving end of the fifth push cylinder 17. After the position of the device is determined, the fifth push cylinder 17 is activated, which will push the fixed toothed plate 18 to connect with the inner wall of the tunnel, thereby fixing the device in the tunnel.

[0026] The positioning marker module 2 includes a fixing block 3, which is connected to the support frame 1. A first push cylinder 4 is connected to the side end of the fixing block 3. The first push cylinder 4 is horizontally set. A transverse moving block 5 is connected to the driving end of the first push cylinder 4. The first push cylinder 4 is used to adjust the horizontal position of the transverse moving block 5. A second push cylinder 6 is connected to the upper end of the transverse moving block 5. The second push cylinder 6 is vertically set. A vertical moving block 7 is connected to the driving end of the second push cylinder 6. The second push cylinder 6 is used to adjust the height of the vertical moving block 7. A laser pointer 8 is connected inside the vertical moving block 7. The laser pointer 8 can irradiate a non-divergent light beam to ensure its accuracy. The light beam is a positioning laser, which irradiates the tunnel rock wall that needs to be blasted.

[0027] A support frame 12 is connected to the side of the vertical moving block 7. A protective cover 13 is rotatably connected to the side of the support frame 12. The support frame 12 is used to support and connect the protective cover 13. The protective cover 13 is located at the emitting head of the laser pointer 8. A third push cylinder 14 is rotatably connected to the upper end of the vertical moving block 7. The driving end of the third push cylinder 14 is rotatably connected to the protective cover 13. Activating the third push cylinder 14 will drive the protective cover 13 to rotate, so that the protective cover 13 can cover the emitting head side of the laser pointer 8 to protect it.

[0028] A horizontal ranging mechanism 9 is connected between the fixed block 3 and the horizontal moving block 5. The horizontal ranging mechanism 9 is used to determine the horizontal position of the laser pointer 8. A vertical ranging mechanism 10 is connected between the horizontal moving block 5 and the vertical moving block 7. The vertical ranging mechanism 10 is used to determine the height position of the laser pointer 8. The horizontal ranging mechanism 9 and the vertical ranging mechanism 10 have the same structure. Taking the horizontal ranging mechanism 9 as an example, it includes: a sleeve 901, a support rod 902 inserted into the sleeve 901, and a ranging pen 903 connected to the side end of the support rod 902. The ranging pen 903 always moves within the sleeve 901. The sleeve 901 can prevent external dust from affecting the ranging of the ranging pen 903, thereby facilitating precise adjustment of the movement of the laser pointer 8.

[0029] In this application, the first pusher cylinder 4, the second pusher cylinder 6, the third pusher cylinder 14, the fourth pusher cylinder 15, and the fifth pusher cylinder 17 are all common electrical devices in the prior art. This application will not elaborate on their models or internal structures, and they can also be replaced by other power sources.

[0030] In use, this invention works as follows: First, a positioning marker module 2 is remotely controlled, causing its internal laser pointer 8 to irradiate a designated drilling position for a peripheral eye. Specifically, a first pusher cylinder 4 moves a horizontal moving block 5, thereby adjusting the horizontal position of the laser pointer 8. A second pusher cylinder 6 moves a vertical moving block 7, thereby adjusting the height of the laser pointer 8. This allows the laser pointer 8 to move in the vertical plane, ensuring that the positioning laser emitted by the laser pointer 8 irradiates the designated drilling position for the peripheral eye. After determining the drilling position, using the position of the laser pointer 8 as a base point, the intelligent control box 11 determines the drilling positions for the remaining peripheral eyes based on the construction drilling drawings. Then, the intelligent control box 11 controls the movement of the other laser pointers 8, ensuring that each laser pointer 8 moves to its corresponding position, thereby performing laser positioning for all peripheral eye drilling positions.
