Description

Technical Field

[0001] The utility model relates to the technical field of traffic planning signal lights, in particular to a fixing device for traffic planning signal lights. Background Art

[0002] In the increasingly complex environment of modern urban transportation systems, traffic lights are like the "commanders" of the traffic network, playing a key role in maintaining efficient and orderly traffic order. The importance of the fixtures used to carry and install traffic lights is self-evident. Traffic light fixtures must not only ensure stable and reliable operation under various harsh weather conditions such as storms, scorching sun, and freezing cold, but also need to balance efficiency and accuracy during the installation process. They must also be easy for staff to operate during subsequent maintenance. A well-designed traffic planning signal light fixture can greatly improve the working efficiency of traffic lights in the entire traffic network and reduce traffic congestion caused by equipment failure or improper installation.

[0003] In the prior art, the installation method of signal lights is relatively traditional. Usually, the signal light group is directly fixed to the mounting frame by bolts. Specifically, in the initial stage of installation, the staff needs to first lift the signal light group to the corresponding position of the mounting frame, and then use tools to pass multiple bolts through the pre-designed mounting holes on the signal light group and the mounting frame in sequence. After the bolts are passed through, the nuts need to be tightened on the other side of the mounting frame. In this process, since the number of bolts and nuts is usually large, the staff needs to spend a lot of time and energy to ensure that each bolt is tightened in place, which further increases the difficulty and time cost of installation.

[0004] However, this traditional installation method has obvious disadvantages. The most prominent problem is that the installation process is complicated and tedious. From preparing the installation tools and carrying the signal light group to installing the bolts one by one, adjusting the position of the signal lights and finally tightening all the nuts, the whole process takes a lot of time and manpower. In addition, due to the numerous installation steps, human errors are prone to occur, such as inconsistent tightening of bolts or inaccurate adjustment of the signal light position. These factors combined lead to very low installation efficiency of the signal lights, seriously affecting the deployment speed of traffic lights in the entire traffic network, and thus causing certain obstacles to the implementation of traffic planning. Therefore, a fixing device for traffic planning signal lights is proposed to solve the above problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1 and Figure 4 - Figure 6The utility model provides an embodiment: a fixing device for a traffic planning signal light, including a cantilever 1, which is made of a hollow rectangular steel tube. The inner and outer walls of the steel tube are rust-proofed. This structure not only reduces the weight but also ensures sufficient strength. A support component is provided on one side of the cantilever 1. The support component is used to maintain the stability of the overall structure. A fixing bolt 2 14 is fixedly connected inside the cantilever 1, and one end of the fixing bolt 2 14 is fixedly connected to a mounting frame 12. The mounting frame 12 is a frame structure made of high-strength aluminum alloy material. It has good stability and corrosion resistance. The mounting frame 12 is fixedly connected with a reinforcing rib 13. The reinforcing rib 13 is to enhance the overall strength of the mounting frame 12. These reinforcing ribs 13 can effectively improve the bearing capacity of the mounting frame 12, so that it can bear the weight of the signal light group 10. The inner wall of the mounting frame 12 is slidably connected with a back plate 11. The back plate 11 is made of stainless steel plate. Its surface is smooth and wear-resistant, which can ensure smooth sliding in the slide rail. The side wall of the back plate 11 is fixedly connected with the signal light group 10. The side wall of the back plate 11 is provided with a lock hole 15. The mounting frame 12 and the back plate 11 are slidably connected with an extension rod 17, and the extension rod 17 is fixedly connected to a limit rod 18 inside. The extension rod 17 and the limit rod 18 can rotate inside the back plate 11 in cooperation with the rotating handle 16. The side wall of the extension rod 17 is fixedly connected to a top rod 19, and the side wall of the top rod 19 is fixedly connected to the rotating handle 16. The outer wall of the top rod 19 is provided with a base 21, and the top rod 19 is slidably connected to the inner wall of the base 21. A spring 20 is provided between the top rod 19 and the base 21, and the spring 20 is used to limit the top rod 19 and the base 21. When pressed down, it can play the role of rebounding and resetting the rotating handle 16. The two ends of the spring 20 are respectively fixed to the outer walls of the top rod 19 and the base 21. The support assembly includes a base 9. The base 9 is a reinforced concrete structure with high stability, good durability and relatively low maintenance cost. The top of the base 9 is fixedly connected to a base column 8, and the top of the base column 8 is fixedly connected to a top column 7. The base column 8 and the top column 7 are both made of steel material with high strength and can withstand the weight of the signal light equipment as well as external forces such as wind and vibration, thereby ensuring the stability of the signal light in various environments;

[0035] Specifically, when the signal light group 10 needs to be installed, the staff can first manually place the signal light group 10 into the mounting bracket 12. At this time, the back panel 11 of the side wall of the signal light group 10 will slide to its bottom along the slide rail inside the mounting bracket 12. The staff further holds the rotating handle 16 to place the locking device into the lock hole 15 opened on the back panel 11 and the side wall of the mounting bracket 12. The shape of the lock hole 15 is consistent with the cross-sectional status of the extension rod 17 and the limit rod 18. The extension rod 17 and the limit rod 18 can be extended into the interior of the back panel 11 along this specific shape. The rotating handle 16 is injection molded with engineering plastic and has anti-slip texture on the outside to facilitate the staff to hold and operate. At this time, the rotating handle 16 can be manually pressed down and rotated. The displacement of the rotating handle 16 compresses the spring 20. 20 is made of highly elastic alloy steel wire, and has long-lasting elasticity and good fatigue resistance. At the same time, the rotation of the rotating handle 16 drives the top rod 19 to rotate, which in turn causes the extension rod 17 to rotate and drives the limit rod 18 to rotate inside the back plate 11. There is a space inside the back plate 11 that can just accommodate the height of the limit rod 18. After releasing the handle, the spring 20 rebounds, so that the limit rod 18 is stuck in the space inside the back plate 11, thereby achieving the effect of quickly fixing the signal light group 10. In actual use, the signal light may need to be replaced due to failure or upgrade. The traditional installation method usually requires the use of tools for tedious screw removal and installation operations, and this detachable design can realize the rapid replacement of the signal light module without the aid of complex tools, greatly improving the efficiency of installation and maintenance.

[0036] Reference Figure 2 and Figure 3 , the outer wall of the top column 7 is provided with a card slot 23, the card slot 23 is used to cooperate with the card block 22 to fix the entire device, the top column 7 top column 7 side wall sliding connection with the connecting plate 5, the connecting plate 5 left and right side walls are rotatably connected to the fixing ring 6, the connecting plate 5 and the fixing ring 6 are made of high-strength alloy steel with good corrosion resistance, the side wall of the fixing ring 6 is fixedly connected with a connecting block 24, the connecting block 24 is used to cooperate with the fixing bolt three 25 to lock the fixing ring 6 on both sides, the fixing ring 6 and the side wall of the connecting plate 5 are fixedly connected with the card block 22, the card block 22 also adopts It is made of the same high-strength alloy steel as the connecting plate 5. The clamping block 22 is slidably connected to the inside of the clamping groove 23. A fixing bolt 3 25 is provided between the connecting blocks 24. The fixing bolt 3 25 is slidably connected to the inside of the connecting block 24. The side wall of the connecting plate 5 is fixedly connected to the fixing plate 4. The side wall of the fixing plate 4 is slidably connected to the base plate 2. The function of the base plate 2 is to transfer the weight generated by the signal light device to the fixing plate 4. A fixing bolt 1 3 is provided between the base plate 2 and the fixing plate 4. The fixing bolt 1 3 is slidably connected to the inside of the base plate 2 and the fixing plate 4.

[0037] Specifically, when installing the cantilever 1, the staff first expands the fixing rings 6 on both sides of the connecting plate 5 located on the side wall of the fixing plate 4 outward in a direction perpendicular to the connecting plate 5, and then lifts the entire device and places it horizontally in the pre-designed slot 23 on the outer wall of the top column 7. During the placement process, the block 22 on the inner wall of the connecting plate 5 is accurately stuck in the inside of the slot 23 along the entrance direction of the slot 23. Then, the staff closes the fixing ring 6 in a direction opposite to the expansion direction, so that the block 22 on the inner wall of the fixing ring 6 is also stuck in the inside of the slot 23 along the direction of the slot 23. The design of the slot 23 and the block 22 enables the components to be quickly initially positioned. This initial positioning can greatly save installation time and improve work efficiency. At the same time, the slot 23 and the block 2 2 The design can evenly distribute the weight of the cantilever 1 and the external force to the supporting structure through the contact surface of the card slot 23 and the card block 22. For example, when the cantilever 1 is subjected to wind force, the force will be evenly transmitted to the column through the card slot 23 and the card block 22, avoiding the problem of local stress concentration. Subsequently, the staff picked up the fixing bolt 3 25, put it inside the connecting block 24, and then used a tool to tighten it by rotating it clockwise. After fixing this part, the base plate 2 is placed horizontally on the other side of the fixing plate 4 so that their mounting holes are aligned. Then, the staff picked up the fixing bolt 1 3 and passed it through the inside of the fixing plate 4 and the base plate 2 in turn. Then, the staff also used a tool to tighten it by rotating it clockwise. Through this operation, the effect of quickly installing the cantilever 1 is achieved.

[0038] Working principle: When the signal light group 10 needs to be installed, the staff can first manually place the signal light group 10 into the mounting frame 12. At this time, the back plate 11 of the side wall of the signal light group 10 will slide to its bottom along the slide rail inside the mounting frame 12. The staff further holds the rotating handle 16 to place the locking device into the lock hole 15 opened on the back plate 11 and the side wall of the mounting frame 12. At this time, the rotating handle 16 can be manually pressed down and rotated. The displacement of the rotating handle 16 compresses the spring 20. At the same time, the rotation of the rotating handle 16 drives the rotation of the top rod 19, which in turn causes the extension rod 17 to rotate and drives the limit rod 18 to rotate. After releasing the hand, the spring 20 rebounds, causing the limit rod 18 to lock. Inside the back plate 11, the signal light group 10 is quickly fixed. When installing the cantilever 1, the staff first unfolds the fixing rings 6 on both sides of the connecting plate 5 on the side wall of the fixing plate 4, and then places the entire device in the slot 23 on the outer wall of the top column 7, so that the block 22 on the inner wall of the connecting plate 5 is stuck in the inside of the slot 23, and then close the fixing ring 6 so that the block 22 on the inner wall of the fixing ring 6 is also stuck in the inside of the slot 23, and then manually put the fixing bolt three 25 inside the connecting block 24 and tighten it. After fixing it, place the base plate 2 on the other side of the fixing plate 4, and manually put the fixing bolt one 3 inside the fixing plate 4 and the base plate 2 and tighten it, so as to achieve the effect of quickly installing the cantilever 1.
