Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tunnel signboards, in particular to a ten-meter signboard for a highway tunnel. Background Art
[0002] At present, the construction of expressways is vigorously carrying out intensive construction and standardized construction. Due to historical reasons, there are problems of multiple road closures at the same time and location during expressway construction, which has brought great inconvenience to drivers and passengers and brought more risks to the construction. This problem is particularly evident in tunnel construction. Intensive construction requires more precise points, so the installation of ten-meter tunnel signs has become a prerequisite, and the original hundred-meter signs have the following problems:
[0003] The original installation of the 100-meter sign has certain sequence requirements. If errors occur during the construction process, it will be troublesome to rework it later.
[0004] The distance between the 100-meter markers is too large to achieve refined maintenance and accurate disease location. Utility Model Content
[0005] The purpose of the utility model is to provide a ten-meter sign for a highway tunnel in view of the deficiencies in the prior art. The utility model replaces the traditional tunnel contour mark with a ten-meter sign and is supplemented with an adjustable digital turntable and a digital wheel locking structure. While achieving adjustable sign identification numbers, the digital disk can be locked to prevent the digital disk from being randomly moved by non-construction personnel after the construction is completed, thereby affecting the subsequent construction positioning.
[0006] In order to achieve the above technical purpose, the utility model adopts the following technical scheme.
[0007] A ten-meter sign for a highway tunnel comprises a sign body, wherein the sign body is installed at intervals of ten meters on the lining on both sides of the tunnel, reflective contour signs are installed on the left and right surfaces of the sign body by means of first bolts, a mounting hole is provided at each of the upper and lower ends of the front side of the sign body, which passes through to the back side of the sign body, an adjustable digital dial is provided between the two mounting holes on the front side of the sign body, a threaded rod is installed at each position corresponding to the two mounting holes on the lining, and after the mounting holes are butted against the threaded rods, the sign body is installed on the lining by means of a first nut.
[0008] Specifically, the adjustable digital turntable includes a first rotating shaft, a sleeve and a digital disc. The rotating shaft is installed inside the signboard body. Multiple digital discs are mounted on the first rotating shaft. Each digital disc is provided with sleeves on both sides. The multiple digital discs are independent of each other and can rotate around the first rotating shaft respectively.
[0009] On the basis of the above technical solution, a number wheel locking structure is also designed, which includes a lock head, a lock shaft, a first connecting rod, a gear lever, a second connecting rod and a second rotating shaft. The lock head is installed between the mounting hole on the front of the sign body and the adjustable number wheel. One end of the lock head with the lock hole faces outward, and the other end is connected to one end of the first connecting rod. The other end of the first connecting rod is hinged to one end of the gear lever, and the other end of the gear lever is hinged to one end of the second connecting rod. The other end of the second connecting rod is hinged to the second rotating shaft. When the numbers on the adjustable number wheel are adjusted, the grooves on the number wheel are aligned one by one. The staff inserts the key into the lock hole and rotates it counterclockwise, driving the lock shaft and the first connecting rod to rotate counterclockwise, so that the gear lever moves into the groove on the number wheel, jams the number wheel, and prevents it from rotating. After the key is pulled out, the number wheel can be locked to prevent non-staff from randomly dialing it.
[0010] Specifically, a gasket is provided between the first nut and the threaded rod.
[0011] Specifically, the outer ring of the number disk has 10 teeth in total, and the numbers 0-9 are arranged in sequence on the outer surfaces of the 10 teeth, and the left and right sides of each tooth are chamfered.
[0012] Specifically, the diameter of the gear lever is smaller than the width of the groove.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] The utility model replaces the traditional 100-meter signboard with a 10-meter signboard and provides an adjustable digital dial, so that the numbers can be uniformly adjusted directly after installation, thereby reducing losses during the construction process and rework due to installation errors.
[0015] The utility model is designed with a digital wheel locking structure, which can lock the digital wheel after the number is adjusted to prevent it from being randomly moved by non-construction personnel and affecting subsequent construction positioning.
[0016] The utility model has the advantages of simple structure, quick and convenient installation and easy popularization and application. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not used to limit the present invention. Example
[0026] like Figure 1-Figure 2 As shown, the utility model provides a ten-meter sign for a highway tunnel, including a sign body 1, wherein the sign body 1 is installed at intervals of ten meters on the lining 2 on both sides of the tunnel, and reflective contour signs 4 are installed on the left and right surfaces of the sign body 1 through first bolts 3, and a mounting hole 5 is respectively provided at the upper and lower ends of the front side of the sign body 1 and penetrates to the back side of the sign body 1, and an adjustable digital dial 6 is provided between the two mounting holes 5 on the front side of the sign body 1, and a threaded rod 7 is respectively installed at the position corresponding to the two mounting holes 5 on the lining 2, and after the mounting holes 5 are connected to the threaded rod 7, the sign body 1 is installed on the lining 2 through a first nut 8.
[0027] like Figure 3 As shown, the adjustable number dial 6 includes a first rotating shaft 9, a sleeve 10 and a number disc 11. The first rotating shaft 9 is installed inside the sign body 1. A plurality of number discs 11 are mounted on the first rotating shaft 9. Each number disc 11 is provided with sleeves 10 on both sides. The plurality of number discs 11 are independent of each other and can rotate around the first rotating shaft 9 respectively.
[0028] like Figure 4As shown, the outer ring of the number disk 11 has 10 teeth in total, a groove 19 is provided between two adjacent teeth, and numbers 0-9 are arranged in sequence on the outer surfaces of the 10 teeth.
[0029] Specifically, a gasket 18 is provided between the first nut 8 and the threaded rod 7 .
[0030] Installation and digital adjustment process:
[0031] First, two threaded rods 7 are fixed on the lining 2 on both sides of the tunnel at the corresponding installation positions of the signboard body 1. The installation height and spacing of the threaded rods 7 match the installation holes 5 on the signboard body 1. Then, the reflective contour signs 4 are installed on the left and right sides of the signboard body 1. After that, the installation holes 5 on the signboard body 1 are connected to the threaded rods 7, and the gaskets 18 are put on the threaded rods 7. The first nut 8 is tightened on the threaded rods 7 to complete the installation of the signboard. Finally, after all the signboards are installed, the numbers of the digital disks 11 on the adjustable digital dial 6 on the front of the signboard body 1 are uniformly adjusted so that the number on each signboard corresponds to its position. Example
[0032] In this embodiment, based on Example 1, Figure 5-Figure 6 As shown, a number wheel locking structure is also designed, which includes a lock head 12, a lock shaft 13, a first connecting rod 14, a gear lever 15, a second connecting rod 16 and a second rotating shaft 17. The lock head 12 is installed between the mounting hole 5 on the front side of the sign body 1 and the adjustable number wheel 6. The end of the lock head 12 with the lock hole faces outward, and the other end is connected to one end of the first connecting rod 14. The other end of the first connecting rod 14 is hinged to one end of the gear lever 15. The other end of the gear lever 15 is hinged to one end of the second connecting rod 16. The other end of the second connecting rod 16 is hinged to the second rotating shaft 17.
[0033] In order to make the lever 15 fit into the groove 19 better, the diameter of the lever 15 is smaller than the width of the groove 19, and both left and right sides of each tooth on the number disk 11 are chamfered.
[0034] Working process:
[0035] The installation and number adjustment process of the sign is consistent with that in Example 1, except that, when the numbers on the adjustable number dial 6 are adjusted, the grooves 19 on the number disc 11 are aligned one by one, and the construction personnel insert the key into the lock hole and rotate it counterclockwise, driving the lock shaft 13 and the first connecting rod 14 to rotate counterclockwise, so that the gear lever 15 moves into the groove 19 on the number disc 11, as shown in FIG. Figure 6As shown, the number disc 11 is stuck to prevent it from rotating. After the key is pulled out, the number disc 11 can be locked to prevent non-construction personnel from randomly turning it. When the number needs to be adjusted, Figure 7 As shown, by inserting the key into the keyhole and turning it clockwise, the lock shaft 13 and the first connecting rod 14 are driven to rotate clockwise, so that the gear lever 15 moves out of the groove 19. At this time, the construction personnel can adjust the numbers on the number disk 11 by fluctuations. After the adjustment is completed, the key is inserted into the keyhole and turned counterclockwise.
[0036] It should be understood that the above description of the preferred embodiment is relatively detailed and cannot be regarded as limiting the scope of patent protection of the utility model.
