[0032] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention. The following describes various embodiments of the present invention in detail with reference to the accompanying drawings.

[0033] Example 1

[0034] See also Figures 1 to 12The present invention preferably provides a technical solution: an automatic lifting device for urban lighting lamp poles, comprising: a step-by-step lifting frame, a pitch storage frame and a double-track reinforcement frame arranged in sequence from bottom to top, which are respectively used to realize the first-level center of gravity lifting protection, the second-level folding storage protection and the third-level retraction reinforcement protection of the lamp body; the double-track reinforcement frame includes a double transmission support rail and a flexible assembly plate installed on the double transmission support rail, wherein the flexible assembly plate can be detachably assembled with the lamp body, and when encountering a strong wind of small intensity, the flexible assembly plate can drive the lamp body to deflect with the wind, thereby reducing the wind-exposed area of ​​the corresponding surface of the lamp body; when encountering a strong wind of small or medium intensity, the double transmission support rail drives the flexible assembly plate to retract, thereby reinforcing the connection position of the flexible assembly plate with it, thereby reducing the risk of excessive shaking of the flexible assembly plate.

[0035] The step-by-step lifting frame, the pitching storage frame and the double-track reinforcement frame provided by the present invention are distributed sequentially from bottom to top and together form a lamp pole for assembling the lamp body, such as Figure 1-5 As shown, in order to enhance the protective performance of the lamp pole, especially the wind resistance, the step-by-step lifting frame, the pitch storage frame and the double-track reinforcement frame provided in the present application respectively realize the three-level protection operation of the lamp body in the form of a first-level center of gravity lifting mode, a second-level folding storage mode and a third-level inward reinforcement mode. Its core benefit is to improve the safety, portability, durability and adaptability of the lamp in many aspects and at many levels, and actively cope with different intensities of strength. It is worth noting that the present application has a built-in wind speed sensor of the prior art, which can determine the wind speed threshold to realize the activation and drive of the step-by-step lifting frame, the pitch storage frame and the double-track reinforcement frame;

[0036] First, when encountering a small strong wind, the flexible assembly plate can drive the lamp body to deflect with the wind, reducing the wind-exposed area of ​​the corresponding surface of the lamp body;

[0037] Secondly, when encountering strong winds of small to medium intensity, the dual drive rails drive the flexible assembly plate to retract, thereby reinforcing the connection between the flexible assembly plate and the rails. This increases the rigidity of the retracted flexible assembly plate, preventing the flexible assembly plate and the lamp body from shifting, loosening, or even breaking due to excessive wind.

[0038] Thirdly, when encountering moderately strong winds, the pitching storage rack can fold the double-track reinforcement frame and its components downward from the original vertical state and store them inside, greatly reducing the wind-exposed area.

[0039] When encountering strong winds, the step-by-step lifting frame is raised and lowered. It is known that lowering the center of gravity is one of the most effective means to prevent tipping over. This greatly improves the stability of the light pole in severe weather conditions such as wind and rain, and reduces damage to the light body, personal injury or other accidents caused by tipping over.

[0040] This application activates different structural designs according to the wind speed, which can significantly improve the protection performance of the device, thereby improving the durability of the device. The retraction, folding, storage and lifting of the lamp pole can improve portability by reducing the volume. At the same time, the height adjustment characteristics of the step-by-step lifting frame further meet the different installation height requirements of the lamp body and improve the applicability of the lamp pole.

[0041] Example 2

[0042] As another embodiment of the present invention, the dual transmission support rail includes an assembly vertical plate 314 connected to the pitch storage rack, a slide rail 3141 is installed on one side of the assembly vertical plate 314, and a transmission seat 315 is provided in the slide rail 3141, wherein the transmission seat 315 is fixedly connected to the flexible assembly plate; and a trapezoidal seat 317 that is slidably installed with the transmission seat 315 through slide grooves 3151 respectively provided on both sides of the transmission seat 315; and also includes a transmission component for the sliding of the trapezoidal seat 317 and the transmission seat 315.

[0043] Combine Figure 8 、 9 As shown in Figure 10, it is known that one side of the transmission seat 315 is slidably installed with the assembly vertical plate 314 through the slide rail 3141 provided on the assembly vertical plate 314, and the trapezoidal seat 317 distributed on the other side is slidably installed with the transmission seat 315 through the slide grooves 3151 respectively opened on both sides of the transmission seat 315. At the same time, the upper part of the transmission seat 315 is fixed to the flexible assembly plate, and the lower part is connected to the electric telescopic rod 324. Under the action of the transmission component, when the electric telescopic rod 324 is telescopically moved, the synchronization and relative sliding process of the transmission seat 315 and the trapezoidal seat 317 can be realized. Please refer to the following for details and will not be repeated here.

[0044] Furthermore, the transmission component includes a mounting block 320 fixed to the side of the assembly vertical plate 314 away from the slide rail 3141, and the mounting block 320 and the transmission seat 315 are respectively fixed with a first transmission member 319 and a second transmission member 316 that are relatively and staggered. Among them, the first transmission member 319 and the second transmission member 316 have the same structure. The first transmission member 319 includes a transmission plate 3191, a groove body provided on the transmission plate 3191, and the groove body includes a straight groove 3192 and a groove 3193 that are connected and connected to each other; and an extension plate 318 fixed to the side of the trapezoidal seat 317 close to the second transmission member 316, and the extension plate 318 is rotatably installed with an extension rod 321 through a rotating shaft; and also includes a second roller 322 and a first roller 323 rotatably installed at both ends of the extension rod 321, and the second roller 322 and the first roller 323 are respectively rotatably installed The wheels 323 are respectively placed inside the groove bodies where the second transmission member 316 and the first transmission member 319 are located; an electric telescopic rod 324 is also provided at the lower part of the assembly vertical plate 314 through a first fixed block, and the electric telescopic rod 324 is fixedly connected to the lower part of the transmission seat 315 through a second fixed block provided at its telescopic end. When the electric telescopic rod 324 retracts, the transmission seat 315 and the trapezoidal seat 317 first slide down synchronously. As the first roller 323 enters the groove 3193 where the first transmission member 319 is located, the transmission seat 315 continues to slide down relative to the trapezoidal seat 317, realizing the sliding and retracting process of the flexible assembly plate; when the electric telescopic rod 324 is extended, the transmission seat 315 slides up first, and when the second roller 322 enters the groove 3193 where the second transmission member 316 is located, the transmission seat 315 drives the trapezoidal seat 317 to slide up synchronously.

[0045] The first transmission member 319 and the second transmission member 316 are fixed on the mounting block 320 and the transmission seat 315 respectively and are arranged in a staggered manner relative to each other. Figure 8 、 9 As shown, the side wall of the trapezoidal seat 317 is provided with a first roller 323 and a second roller 322 through an extension plate 318 and an extension rod 321. At this time, when the electric telescopic rod 324 is Figure 8 When the transmission seat 315 is pushed upward, the second roller 322 does not enter the groove 3193 where the second transmission member 316 is located, but rolls on the surface of the straight groove 3192. At this time, the transmission seat 315 first moves upward alone. As the second roller 322 enters the groove 3193 where the second transmission member 316 is located, the trapezoidal seat 317 and the transmission seat 315 can be limited. At this time, the transmission seat 315 drives the trapezoidal seat 317 to move upward synchronously, thereby further ejecting the flexible assembly plate.

[0046] When the electric telescopic rod 324 pulls down the transmission seat 315, the transmission seat 315 and the trapezoidal seat 317 also slide down first. During this process, the first roller 323 rolls inside the straight groove 3192 where the first transmission member 319 is located. As the first roller 323 enters the groove 3193 where the first transmission member 319 is located, Figure 6 、9 As shown in the state, the position of the trapezoidal seat 317 is locked, and the transmission seat 315 continues to slide down relative to the trapezoidal seat 317, thereby Figure 8 The state is further retracted to the inside of the protective structure formed by the assembly vertical plate 314 and the trapezoidal seat 317.

[0047] Furthermore, the flexible assembly plate includes a sleeve body consisting of a flexible sleeve 411 and a rigid sleeve 413, wherein the bottom of the rigid sleeve 413 is fixed to the top of the transmission seat 315, and a fastening component is provided between its side wall and the trapezoidal seat 317; and an assembly plate body 412 embedded in the sleeve body and used for assembling the lamp body; two transverse axes 414 provided in the middle of the rigid sleeve 413; two transmission columns 415 fixed to the bottom of the assembly plate body 412, wherein the two transmission columns 415 are respectively sleeved on the two transverse axes 414 through hexagonal grooves 416 opened thereon; wedge-shaped fixing blocks 417 are respectively fixed on both sides of the bottom inner side of the rigid sleeve 413; and also includes a trapezoidal transmission block 418 installed on the bottom inner side of the rigid sleeve 413 and capable of horizontal limited sliding, wherein the trapezoidal transmission block 418 and the two wedge-shaped fixing blocks 417 on both sides thereof respectively constitute limiting grooves, each limiting groove is provided with a rolling ball 419, and the two rolling balls 419 respectively abut against the two transmission columns 415.

[0048] like Figure 10 、 11 As shown in Figure 12, the assembly plate 412 for assembling the lamp body can be embedded in the sleeve body composed of the flexible sleeve 411 and the rigid sleeve 413. At the same time, the two transmission columns 415 fixed at the bottom of the assembly plate 412 are respectively mounted on the two horizontal shafts 414 fixed at the lower part of the rigid sleeve 413 through the hexagonal grooves 416. The two transmission columns 415 are respectively in contact with the rolling balls 419 inside the two limiting grooves. It is worth mentioning that the trapezoidal transmission block 418 can slide horizontally within the bottom of the rigid sleeve 413. Therefore, when the assembly plate 412 is attacked by a small wind, the two transmission columns 415 at the bottom of the assembly plate 412 can not only shake slightly on the two horizontal shafts 414, but also can Figure 12 When it deviates left or right, its tilt angle can be adaptively adjusted according to the wind direction and automatically reset to reflect its flexible wind resistance performance.

[0049] Furthermore, the fastening assembly includes a through slot opened in the middle of the trapezoidal seat 317; and a splint 420 slidably mounted on the surface of the trapezoidal seat 317; and also includes a telescopic sleeve 421 fixed to the side wall of the rigid sleeve 413, and a telescopic column 422 is provided in the telescopic sleeve 421, wherein the outer end of the telescopic column 422 passes through the through slot and is connected to the connecting sleeve 424 fixed to the side wall of the splint 420; a spring 423 is provided on the outer wall of the telescopic column 422 between the connecting sleeve 424 and the telescopic sleeve 421.

[0050] like Figure 10 、 11As shown, since the rigid sleeve 413 is fixed to the transmission seat 315, in order to improve the connection stability between the two, the present application provides a telescopic sleeve 421 on the side wall of the rigid sleeve 413, and a telescopic column 422 is provided in the telescopic sleeve 421, the outer end of which is fixed to the connecting sleeve 424 on the side wall of the splint 420, and a spring 423 is provided in the middle thereof, as shown in FIG. Figure 11 As shown, when subjected to a certain intensity of wind attack, the electric telescopic rod 324 drives the flexible assembly plate to move downward as a whole, and at this time the splint 420 can move downward on the surface of the trapezoidal seat 317. Figure 9 As shown, they increase from top to bottom, thereby pulling the splint 420 and the rigid sleeve 413 apart. At this time, through the action of the spring 423, the rigid sleeve 413 and the splint 420 can clamp the trapezoidal seat 317, thereby strengthening the connection stability between the flexible assembly plate and the dual transmission support rail.

[0053] Furthermore, sprocket drive assemblies are symmetrically arranged on the opposite sides of the C-shaped frame 211, which are respectively used to drive the two sets of transmission rail assemblies to operate; each set of sprocket drive assemblies includes four sprocket bodies 212 rotatably mounted on the inner wall of the C-shaped frame 211; and a chain 213 sleeved on the four sprocket bodies 212, wherein the chain 213 is hinged to the second slider 217 and is divided as a whole into a vertical section on one side and an inclined upper section and a wavy lower section on the other side; it also includes a first motor 223 arranged on the outer wall of the C-shaped frame 211, and the output shaft of the first motor 223 passes through a through hole opened in the side wall of the C-shaped frame 211 and is fixed to one of the sprocket bodies 212.

[0054] In this embodiment, the two sets of transmission rail assemblies are arranged relative to each other, and the assembly riser 314 equipped with a double-track reinforcement frame can be rotatably installed with the two support plates 312 via a transmission shaft 313. The two support plates 312 are respectively fixed to one of the opposite ends of the transverse rail 216 where the two sets of transmission rail assemblies are located. At the same time, the gears 222 fixed at both ends of the transmission shaft 313 are engaged with the racks 221 where the two sets of transmission rail assemblies are located. When the two sets of transmission rail assemblies are in operation, the assembly riser 314 can be folded and stored.

Each chain 213 is divided into a vertical section on one side and an inclined upper section and a wavy lower section on the other side.

[0056] First, the rotation direction of the chain 213 of the present application is as follows Figure 7 The second slider 217 is deflected clockwise in the middle, so when the chain 213 drives the second slider 217 to pass through the vertical section where it is located, the second slider 217 can drive the horizontal rail 216 and the first slider 215 connected thereto to move upward inside the vertical rail 214.
