Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a laser positioning device for a tunnel waterproof gasket. Background Art

[0002] Tunnel waterproofing is a key component of the tunnel structure. Its construction quality is a crucial factor in determining the effectiveness of tunnel waterproofing, and the smoothness of its installation is crucial for the density of the lining structure. During the installation process, ensuring uniformity in the placement of the gaskets and the fixing points of the waterproofing is the most direct and effective way to control its construction quality.

[0003] When using traditional manual marking, there will be accumulated errors in the manual measurement process, resulting in low accuracy in the placement of gaskets. It is difficult to form a large-area, high-precision gasket array, and the overall construction time is long.

[0004] A flashlight-type starry sky laser light is used to arrange the gasket array. The light is projected by a light source, which causes the distance between the laser points projected onto the wall to increase from the middle to the periphery. The distance between each adjacent laser point is inconsistent, making it impossible to arrange a large area of ​​regular gaskets. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0026] like Figure 1-8 As shown, a laser positioning device for a tunnel waterproof gasket includes a support rod 1, a laser box 2, and a laser lamp A arranged inside the laser box 2. Several laser boxes 2 are inserted into the support rod 1, and the support rod 1 is supported on a stand B. The stand B is a frame structure and is movably arranged inside the tunnel. The laser box 2 is composed of a support plate I 21 and a support plate II 22. The support plate I 21 and the support plate II 22 are connected by bolts. A transparent connecting plate 23 is provided on the support plate II 22. The support plate I 21, the support plate II 22 and the connecting plate 23 are enclosed into a box shape. An adjustment component 3 is rotatably provided inside the laser box 2. The adjustment component 3 is connected to the laser lamp A. The rotation of the adjustment component 3 changes the angle of the laser lamp A.

[0027] Example 1

[0028] like Figure 1-4As shown, the adjustment assembly 3 includes a gear 31 and a rack 32 meshing with the gear 31. The rack 32 is arc-shaped. The laser lamp A is connected to the rack 32, and the laser lamp A is set toward the connecting plate 23. The gear 31 is rotatably arranged between the support plate I21 and the support plate II22. The gear 31 is connected to an adjusting rod for driving the gear 31 to rotate. The adjusting rod passes through the laser box 2. The adjusting rod includes a connecting rod 34 and a knob 33 connected to one end of the connecting rod 34. The connecting rod 34 is connected to the gear 31. An arc-shaped slide groove 321 is provided on the support plate II22. A slider 322 is provided at one end of the arc-shaped rack 32. The slider 322 extends into the slide groove 321. When the knob 33 is turned, the knob 33 drives the connecting rod 34 to rotate, and the connecting rod 34 causes the gear 31 to rotate. Since the gear 31 is meshed with the rack 32, the rack 32 slides along the slide groove 321 during the rotation of the gear 31, thereby changing the angle of the laser lamp A.

[0029] Example 2

[0030] like Figure 1 、 2 As shown in Figures 5 and 6, the adjustment component 3 includes an adjusting rod and a connecting block 35 fixedly connected to the adjusting rod. One end of the adjusting rod passes through the support plate I 21, and the adjusting rod is rotatably connected to the laser box 2. The adjusting rod includes a connecting rod 34 and a knob 33 connected to one end of the connecting rod 34. The connecting rod 34 is connected to the connecting block 35. The knob 33 is set on the outside of the support plate I 21. The laser lamp A is connected to one end of the connecting block 35. The laser lamp A is set toward the connecting plate 23. When the knob 33 is turned, the knob 33 drives the connecting rod 34 to rotate. When the connecting rod 34 rotates, the connecting block 35 rotates synchronously, so that the angle of the laser lamp A changes.

[0031] Example 3

[0032] like Figure 1 、 2As shown in Figures 7 and 8, the adjustment assembly 3 includes a connecting rod 37 and an adjusting rod. A rotating shaft 37 is provided on the support plate II 22. One end of the connecting rod 36 is connected to the rotating shaft 37. The laser lamp A is provided at the other end of the connecting rod 36. The adjusting rod is provided in the middle of the connecting rod 36. An arc-shaped groove 211 is provided on the support plate I 21. The adjusting rod includes a connecting rod 34 and a knob 33 provided at one end of the connecting rod 34. The connecting rod 34 is fixedly connected to the connecting rod 36, and the connecting rod 34 is provided in the groove 211. The knob 33 is set on the outside of the support plate I 21. The knob 33 and the connecting rod 34 are connected by a thread. The sliding knob 33 causes the connecting rod 34 to slide along the groove 211. During the sliding process, the connecting rod 34 drives the connecting rod 36 to rotate with the rotating shaft 37 as the center, so that the angle of the laser lamp A changes. When the laser lamp A reaches the specified position, the knob 33 is rotated to move toward the support plate I 21 and tightly adhere to the surface of the support plate I 21 to prevent the laser lamp A from angular deviation.

[0033] In order to avoid the laser being blocked by stand B, the laser device is installed on the outside of the flange of stand B to facilitate the projection and illumination of the laser on the arch wall. Depending on the size of the tunnel section and the size of stand B, the number of laser lights A installed on each layer of stand B is also different. When installing the device, the three-dimensional orientation principle of the total station is used to fix each device on stand B at the same mileage and elevation, so that the laser device can be accurately positioned. The laser points projected by the precisely positioned laser light A can also form an accurate matrix of light points on the tunnel arch wall. During construction, workers install waterproof gaskets along the laser points, and the array of gaskets arranged can achieve the effect of being straight in the circumferential and longitudinal directions and in a fixed relationship with the center line of the tunnel. For subsequent construction, it is only necessary to turn on the power to project all the gasket points onto the tunnel arch wall at once, which is convenient and quick. By adjusting the distance of the laser box 2 and the irradiation angle of the laser lamp A, the distance of the projected light spot can be adjusted at will, ensuring the accuracy of the light spot array. In addition, the entire device is small in size, simple in structure, easy to produce and process, flexible to install on the stand, not easy to be damaged after installation, and simple to maintain.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
