Detailed implementation manners

[0025] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0027] As Figure 1 And Figure 2 shown, a structural diagram of a searchlight traffic warning light for a tunnel 1 provided by an embodiment of the present invention includes:

[0028] A guide rail bracket 2 fixedly arranged on the top of the tunnel body of the tunnel 1, the guide rail bracket 2 is of an arc-shaped structure, and both ends of the guide rail bracket 2 extend to both sides of the tunnel 1, and further includes:

[0029] The mounting frame 3 is slidably arranged on the guide rail frame 2. The mounting frames 3 are located on both sides of the tunnel body. On the side of the mounting frame 3 facing the inside of the tunnel 1, an indicator light 4 is arranged. The indicator lights 4 on both sides correspond to the positions of the lanes respectively. The two mounting frames 3 are fixedly connected through a connecting frame 5 located inside the guide rail frame 2.

[0030] The driving unit 6 is arranged at both ends of the guide rail frame 2 and is located on both sides of the tunnel body of the tunnel 1. A pull wire 601 located inside the guide rail frame 2 is arranged at the output end of the driving unit 6. The pull wires 601 of the driving units 6 on both sides are respectively connected to the mounting frames 3 on both sides. The driving unit 6 is used to reel in the pull wire 601 inside the corresponding side of the guide rail frame 2, so that the mounting frames 3 on both sides move towards one end on the guide rail frame 2.

[0031] In an embodiment of the present invention, when the present invention is in use, the mounting frames 3 on both sides form an integral body through the connecting frame 5. When the indicator lights 4 are normally put into use, the pull wires 601 on both sides can be controlled by the driving units 6 on both sides, and the positions of the indicator lights 4 on both sides can be adjusted. When the indicator lights 4 need to be maintained or replaced, by controlling the driving unit 6 on one side, the pull wire 601 will drive the mounting frame 3 to move towards this side. This operation can be carried out on both sides of the tunnel 1, and it can be selected according to the actual situation. When the mounting frame 3 moves to one side of the tunnel 1, due to the characteristics of its own shape, the mounting frame 3 will also lower its height, so that the maintenance work can be carried out conveniently, and it will not affect the driving in the tunnel 1 and will not have an impact on the traffic.

[0032] In an example of the present invention, as Figure 3 shown, the driving unit 6 includes a box body 602 fixedly connected to both ends of the guide rail frame 2. A driving shaft 603 is horizontally arranged and rotatably connected to the bottom of the box body 602. A first handle 604 is fixedly connected to the end of the driving shaft 603 located outside the box body 602. A lock box 605 is fixedly connected to one side of the box body 602. The first handle 604 is located inside the lock box 605. The pull wire 601 is wound around the driving shaft 603, and a round hole is opened at the top of the box body 602. The pull wire 601 is slidably arranged in the round hole. When the indicator light 4 needs to be maintained, the driving shaft 603 is controlled to rotate through the first handle 604, so that the pull wire 601 is wound around the driving shaft 603. At this time, the pull wire 601 will drive the mounting frame 3 to move towards this side, and the height of the indicator light 4 can be reduced, which is convenient for the maintenance. A box door 606 is rotatably arranged on the side of the lock box 605 far away from the box body 602. A switch lock is arranged on the box door 606, so that the lock box 605 cannot be opened casually, and only professional personnel can perform this operation.

[0033] As Figure 3 and Figure 4As shown, as a preferred embodiment of the present invention, a locking unit 7 is provided on the top of the box body 602 , and the locking unit 7 is used to fix the pull wire 601 .

[0034] In one case of the present embodiment, the pull wire 601 can be clamped and fixed by setting a locking unit 7. When the pull wires 601 on both sides are fixed, the position of the indicator light 4 on the top of the tunnel 1 is fixed. The locking unit 7 includes a clamping plate 701 rotatably connected to the top of the box body 602. The clamping plates 701 are located on both sides of the pull wire 601. A vertically arranged mounting rod 702 is fixedly connected to the top of the box body 602. A push plate 703 is slidably arranged at the bottom of the mounting rod 702. The push plate 703 is located between the clamping plates 701. An elastic member 704 is fixedly connected between the push plates 703 on both sides. The elastic member 704 can be a spring, and of course, an elastic air cushion can also be used. The width of the push plate 703 on one side of the clamping plate 701 is smaller than the width on the other side. An adjusting screw 705 is provided on the side wall of the box body 602, one end of the adjusting screw 705 is rotatably connected to the push plate 703, the other end of the adjusting screw 705 is located in the lock box 605, and the end of the adjusting screw 705 is fixedly connected to the second handle 706, and the adjusting screw 705 is driven to rotate by the second handle 706, and the push plate 703 can only move laterally under the restriction of the mounting rod 702, at this time, it will push the splints 701 on both sides to open, so that the pull wire 601 can move smoothly, and the first handle 604 can control the movement of the mounting frame 3, and after the push plate 703 is reset, the elastic member 704 will pull the splints 701 on both sides together, and the splints 701 can clamp the pull wire 601 from both sides, so that the pull wire 601 will not move easily.

[0035] like Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, the guide rail frame 2 includes guide bars 201 located on both sides of the mounting frame 3, the guide bars 201 are fixedly connected to the inner wall of the tunnel 1, and a guide groove 202 is opened on the side of the guide bar 201 facing the other side of the guide bar 201, the mounting frame 3 slides and is clamped in the guide grooves 202 on both sides, the pull wire 601 is located in the guide groove 202 of the guide bar 201 on one side, the pull wire 601 is wrapped around the side of the drive shaft 603 close to the first handle 604, and the side of the drive shaft 603 away from the first handle 604 is wrapped with a cable 8, the other end of the cable 8 is fixedly connected to the mounting frame 3, and the cable 8 is located in the guide groove 202 of the guide bar 201 on the other side.

[0036] In a case of this embodiment, the cable 8 and the stay wire 601 are respectively arranged in the two side guide grooves 202, which can ensure that during the movement of the mounting frame 3, the cable 8 and the stay wire 601 will not fall off the guide rail frame 2, avoiding the situation that affects the operation of the vehicle. And setting the cable 8 in the same form as the stay wire 601 can enable the moving indicator light 4 to be powered on and work at any time. Wear-resistant protective layers are provided outside both the cable 8 and the stay wire 601. Because during the movement of the mounting frame 3, the stay wire 601 and the cable 8 will inevitably rub against the guide rail frame 2, the existence of the wear-resistant protective layer can prevent the stay wire 601 and the cable 8 from being damaged.

[0037] As Figure 5 and Figure 6 shown, as a preferred embodiment of the present invention, a telescopic structure 9 is provided on the connecting frame 5. The telescopic structure 9 is used to adjust the length of the connecting frame 5, and the indicator light 4 is rotatably arranged on the mounting frame 3.

[0038] In a case of this embodiment, a locking structure 10 is provided at the connection between the mounting frame 3 and the indicator light 4. The locking structure 10 is used to limit the rotation of the indicator light 4. The connecting frame 5 includes an arc-shaped sleeve 901 fixedly connected to one side mounting frame 3 and an arc-shaped inner tube 902 fixedly connected to the other side mounting frame 3. The arc-shaped sleeve 901 is slidably sleeved outside the arc-shaped inner tube 902. The telescopic structure 9 includes an adjusting screw rod 903 cooperatively connected to the arc-shaped sleeve 901. The adjusting screw rod 903 is located between the guide rail strips 201. The adjusting screw rod 903 can press the arc-shaped inner tube 902 in the arc-shaped sleeve 901, so that the length of the connecting frame 5 is fixed. Through the above structure, the distance between the two side indicator lights 4 can be adjusted. The mounting frame 3 and the indicator light 4 are connected by a turntable, and the locking structure 10 can adopt a locking bolt arranged on the turntable. Rotating the locking bolt can clamp the turntable, so that the indicator light 4 is fixed. Through the above structure, the angle between the mounting frame 3 and the indicator light 4 can be adjusted. After the distance between the mounting frames 3 and the indicator lights 4 can be adjusted, through the cooperation of the driving unit 6 and the two side stay wires 601, the positions of the two side indicator lights 4 in the tunnel 1 can be adjusted, which is convenient for flexible adjustment.
