This utility model utilizes a gripping mechanism to fix the light pole, and a traction mechanism to pull the lifting rod to rotate around the support crossbar, thus lifting a horizontally placed light pole to a vertical position. This significantly reduces the need for manual lifting or the use of other auxiliary equipment, lightens the workload of workers, has a high safety factor, and greatly improves work efficiency.

[0003] The aforementioned disclosure describes how a traction mechanism pulls a lifting rod around a supporting horizontal plate to lift a horizontally placed light pole into a vertical position. Currently, light poles are typically lifted by attaching ropes to the end of the pole and pulling it upwards until it is vertically suspended. When the light pole is vertically suspended, the ropes will swing, posing a risk of collision with workers and creating a safety hazard. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lifting device for traffic signal poles. It solves the problem that the lifting of light poles typically involves attaching ropes to the end of the pole and pulling it upwards until it is vertically suspended. However, when the light pole is vertically suspended, the ropes swing, which poses a risk of collision with workers and creates a safety hazard.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for traffic signal poles, comprising a support frame, a lifting frame slidably connected between the four uprights of the support frame, a first fixing device rotatably connected to the bottom of the lifting frame for clamping one end of the pole, a guide device movably mounted on the bottom of the support frame, a lifting device slidably connected to the upper surface of the guide device, a second fixing device rotatably connected to the top of the lifting device for clamping and fixing the other end of the pole, and a lifting device fixedly mounted on the top of the support frame for driving the lifting frame to move up and down.

[0006] Preferably, the lifting device includes a winding reel, and a lifting cable is provided between the winding reel and the lifting frame.

[0007] Preferably, the lifting frame includes two connecting rods, a connecting plate is fixedly connected between the two connecting rods, the first fixing device is rotatably connected to the bottom of the connecting plate, a first T-shaped block is fixedly connected to the end of the connecting rod, and a first T-shaped groove matching the first T-shaped block is opened on the upright of the support frame.

[0008] Preferably, the first fixing device includes a first sleeve and a second sleeve, which are fixedly connected by multiple safety connecting slings, and the second fixing device includes a third sleeve.

[0009] Preferably, the first sleeve, the second sleeve, and the third sleeve are all threaded with multiple adjusting bolts on their periphery, and the ends of the adjusting bolts extend into the first sleeve, the second sleeve, and the third sleeve respectively and are rotatably connected to a pressing block.

[0010] Preferably, the guiding device includes a guide rail, the upper surface of the bottom of the support frame is provided with a groove that matches the guide rail, the bottom of the lifting device is rotatably connected with multiple rollers, and the upper surface of the guide rail is provided with a guide groove that matches the rollers.

[0011] Preferably, a second T-shaped block is fixedly connected to the side of the guide rail, and a second T-shaped groove matching the second T-shaped block is formed on the inner wall of the slide. Beneficial effects

[0012] This utility model provides a lifting device for traffic signal poles. Compared with the prior art, it has the following advantages:

[0013] (1) The lifting equipment for traffic signal poles, by setting a first fixing device, the end of the pole is fitted into the first sleeve, and the first sleeve is rotatably connected to the lifting frame, so that the lifting frame rises and can pull and drive the pole to rotate into a vertical state. The lifting frame replaces the rope to drive the end of the pole to move upward, and the end of the lifting frame is slidably connected to the upright of the support frame, so that the upright can limit the lifting frame and prevent it from swaying left and right, so that when the pole is suspended in the air, there will be no large-scale swaying.

[0014] (2) When the lifting equipment for traffic signal poles is used to lift the pole, if the other end of the pole is displaced and slides during the lifting process due to its own tilt, the other end of the pole is supported on the lifting device, and the lifting device moves under the action of the rollers, which can reduce the friction between the pole and the ground, thereby reducing the damage of the pole to the ground. Moreover, due to the limit of the guide rail, when the pole is suspended and swaying, it can only sway in the direction guided by the guide rail, so that the pole will not sway irregularly and reduce the risk of accidents.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a lifting device for traffic signal poles, including a support frame 1, a lifting frame 2 slidably connected between the four uprights of the support frame 1, a first fixing device 4 rotatably connected to the bottom of the lifting frame 2 to clamp one end of the light pole, a guide device 5 movably installed at the bottom of the support frame 1, a lifting device 6 slidably connected to the upper surface of the guide device 5, a second fixing device 7 rotatably connected to the top of the lifting device 6, the second fixing device 7 being used to clamp and fix the other end of the light pole, and a lifting device 3 fixedly installed at the top of the support frame 1 to drive the lifting frame 2 to move up and down.

[0023] Specifically, the support frame 1 supports the lifting frame 2. To facilitate the movement of the support frame 1, casters can be installed at the bottom of the support frame 1. The first fixing device 4 is sleeved and clamped on one end of the lamp post, and the second fixing device 7 is sleeved and clamped on the other end of the lamp post. When the lifting frame 2 moves upward, the first fixing device 4 drives one end of the lamp post to tilt up until the other end of the lamp post is suspended in the air. The second fixing device 7 is set on the lifting device 6. The lifting device 6 is slidably connected to the guide device 5, so that when one end of the lamp post tilts up and drives the other end of the lamp post to slide, it can slide under the action of the lifting device 6, avoiding direct friction between the end of the lamp post and the ground, thus preventing damage to the ground.

[0024] The lifting device 3 includes a winding reel 31, and a lifting cable is provided between the winding reel 31 and the lifting frame 2.

[0025] Specifically, the winding reel 31 winds up the sling, thereby causing the lifting frame 2 to move upward.

[0026] The lifting frame 2 includes two connecting rods 21, and a connecting plate 22 is fixedly connected between the two connecting rods 21. The first fixing device 4 is rotatably connected to the bottom of the connecting plate 22. The end of the connecting rod 21 is fixedly connected to a first T-shaped block 211. The upright of the support frame 1 is provided with a first T-shaped groove 11 that matches the first T-shaped block 211.

[0027] Specifically, the cooperation of the first T-shaped block 211 and the first T-shaped groove 11 allows the lifting frame 2 to slide up and down between the uprights on the support frame 1 without any left or right deviation or swaying. This allows the light pole to be pulled when it is suspended and swaying, thus preventing it from swaying significantly.

[0028] The first fixing device 4 includes a first sleeve 41 and a second sleeve 42, which are fixedly connected by multiple safety connecting slings 43. The second fixing device 7 includes a third sleeve 71.

[0029] Specifically, the first hoop 41 is fitted onto one end of the light pole, the third hoop 71 is fitted onto the other end of the light pole, and the second hoop 42 is fitted onto the perimeter of the light pole. The safety connecting sling 43 works in conjunction with the second hoop 42 to provide safety protection when lifting the light pole. This prevents the light pole from falling directly to the ground and causing a safety accident if the light pole comes off the first hoop 41 during lifting.

[0030] The first sleeve 41, the second sleeve 42, and the third sleeve 71 are all threaded with multiple adjusting bolts 72. The ends of the adjusting bolts 72 extend into the first sleeve 41, the second sleeve 42, and the third sleeve 71 respectively and are rotatably connected to the pressing blocks 73.

[0031] Specifically, rotating the adjusting bolt 72 causes the pressing block 73 to move and press the periphery of the lamp post, thus fixing the position of the lamp post.

[0032] The guide device 5 includes a guide rail 51. The upper surface of the bottom of the support frame 1 is provided with a groove 12 that matches the guide rail 51. The bottom of the lifting device 6 is rotatably connected with multiple rollers. The upper surface of the guide rail 51 is provided with a guide groove 52 that matches the rollers.

[0033] Specifically, when suspending the light pole, the lifting height of the light pole is controlled so that while the light pole is suspended in the air, the rollers on the lifting device 6 do not disengage from the guide groove 52. The rollers roll in the guide groove 52, reducing the friction between the lifting device 6 and the guide rail 51. The guide groove 52 can limit the movement direction of the lifting device 6, so that it can only move back and forth along the guide groove 52. Thus, when the light pole is suspended in the air, the swaying of the light pole can only be guided by the guide groove 52.

[0034] The guide rail 51 is fixedly connected to the side of the second T-shaped block 53, and the inner wall of the slide groove 12 is provided with a second T-shaped groove that matches the second T-shaped block 53.

[0035] Specifically, the second T-shaped block 53 and the second T-shaped groove enable the guide rail 51 to be stably connected to the bottom of the support frame 1 and to be easily disassembled.
