[0002] Traffic lights at intersections on city roads direct traffic, providing clear guidance for vehicles and pedestrians crossing the road and effectively preventing traffic accidents.

[0003] Existing traffic light poles, such as the intelligent traffic light pole for easy climbing and maintenance disclosed in announcement number CN210529536U and another intelligent traffic light pole for easy climbing and maintenance disclosed in announcement number CN216287072U, both employ a fixed high-level erection method for horizontally mounted poles. Ladders or steps are then used to facilitate workers' access to the high-level poles for inspection and maintenance. However, working at heights presents inherent risks and significantly complicates maintenance and safety procedures. While existing methods utilize movable horizontal bars, these horizontally extended bars, while possessing considerable weight, also need to support numerous traffic light devices. The single-point connection between the horizontal bar and the vertical pole makes it extremely difficult to ensure installation stability. Furthermore, raising and lowering the heavy horizontal bar is time-consuming and labor-intensive. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Reference Figures 1-4The adjustable traffic light pole includes a base 1 with multiple through holes for mounting screws to facilitate fixed installation on the ground. A hollow load-bearing guide rod 2 is integrally connected to the base 1. Multiple circumferentially equidistant reinforcing ribs are provided on the base 1 to enhance the installation stability of the load-bearing guide rod 2. A controller 3 is fixedly installed on the load-bearing guide rod 2, and a vertically lifting platform 4 is movably mounted on the load-bearing guide rod 2. It should be noted that guide rails 201 for the sliding assembly of the lifting platform 4 are symmetrically welded to the front and rear sides of the load-bearing guide rod 2, and guide holes 202 for the sliding assembly of the lifting platform 4 are symmetrically provided on the left and right sides of the load-bearing guide rod 2, making the lifting platform 4 a double-layered structure to enhance its connection with the load-bearing guide rod 2.

[0034] A traction mechanism is provided between the controller 3 and the lifting platform 4. Please refer to the instruction manual for details. Figure 3 With appendix Figure 4 The traction mechanism includes a traction roller 7 rotatably mounted on the load-bearing guide rod 2 and controlled to rotate by the controller 3. A fixed pulley block 8 is fixedly installed inside the top of the load-bearing guide rod 2, and the lifting platform 4 is integrally connected to the connecting frame 10 located inside the load-bearing guide rod 2 through the guide elongated hole 202. A movable pulley block 9 is fixedly connected to the connecting frame 10. A traction rope 11 is fixedly connected between the traction roller 7 and the fixed pulley block 8 through the movable pulley block 9. The controller 3 controls the traction roller 7 to rotate in both directions to wind up or release the traction rope 11. The winding operation can vertically lift the lifting platform 4, so that the light pole group 6 is raised synchronously. The releasing operation can vertically lower the lifting platform 4, so that the light pole group 6 is lowered synchronously, so that the workers on the ground can carry out maintenance, thereby avoiding high-altitude operations.

[0035] Further explanation:

[0036] First, the fixed pulley block 8 includes a first clamping plate 801. The first clamping plate 801 is symmetrically welded with a first upper hook 802 and a first lower hook 803 at its upper and lower ends. The first clamping plate 801 is rotatably mounted with a first upper pulley 804 and a first lower pulley 805 distributed from top to bottom.

[0037] Second, the movable pulley block 9 includes a second clamping plate 901. The upper and lower ends of the second clamping plate 901 are symmetrically welded with a second upper hook 902 and a second lower hook 903. The second clamping plate 901 is rotatably mounted with a second upper pulley 904 and a second lower pulley 905 distributed from top to bottom.

[0038] Third, the fixed pulley block 8 is fixedly connected to the top of the load-bearing guide rod 2 through the first upper hook 802, and the fixed pulley block 8 is fixedly connected to one end of the traction rope 11 through the first lower hook 803, and the other end of the traction rope 11 is fixedly connected to the traction roller 7.

[0039] It is worth noting that the first upper pulley 804 and the second lower pulley 905 are both large pulleys with a diameter of 15cm, while the first lower pulley 805 and the second upper pulley 904 are both small pulleys with a diameter of 10cm. This ensures that the traction rope 11 still has gap space after repeated winding, thus avoiding confusion between them.

[0040] Fourth, the movable pulley block 9 is fixedly connected to the connecting frame 10 via the second lower hook 903.

[0041] Fifth, please refer to the appendix of the instruction manual for details. Figure 4 The traction rope 11 passes sequentially from the traction roller 7 through the first upper pulley 804, the second lower pulley 905, the first lower pulley 805, the second upper pulley 904, and finally to the first lower hook 803. By increasing the number of turns of the traction rope 11, multiple layers of force are distributed, thereby achieving a labor-saving effect.

[0042] Lifting boxes 5 are fixedly installed on the front and rear sides of the lifting platform 4. The lifting boxes 5 can accommodate one person, so as to support maintenance personnel to lift the platform to a certain height and observe the top part of the load-bearing guide rod 2.

[0043] The right side of the lifting platform 4 is fixedly equipped with a light pole assembly 6, please refer to the instruction manual for details. Figure 1 - Appendix Figure 3 The lamp post assembly 6 includes a crossbar 601 and a traction rod 602 fixedly installed on the right side of the lifting platform 4. A connecting rod 603 is fixedly connected to the free end of the crossbar 601. The connecting rod 603 is threadedly connected to a threaded hole connecting plate 604. A threaded sleeve 605 that rotatably connects to the traction rod 602 is threadedly installed at the other end of the threaded hole connecting plate 604. The threaded sleeve 605 is rotated in the threaded hole connecting plate 604 with the traction rod 602 as the force point, so that the traction rod 602 can provide traction to the end of the crossbar 601 away from the lifting platform 4, ensuring the stability of the horizontal extension of the crossbar 601.

[0044] It should be noted that the specific model and specifications of controller 3 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0045] The functional principle of this utility model can be explained through the following operation methods:

[0046] When the light pole assembly 6 needs to be inspected, the controller 3 drives the traction roller 7 to rotate, so as to release the traction rope 11 in an orderly manner. The moving pulley assembly 9 and the connecting frame 10 drive the lifting platform 4 to move vertically down along the guide rail 201 and the guide elongated hole 202 to the inspection height position.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
