Description

Technical Field

[0001] This invention relates to the field of light pole lifting technology, specifically to an automatic lifting device for urban lighting poles. Background Technology

[0002] The automatic lifting function of urban lighting poles is mainly for the purpose of facilitating maintenance, improving efficiency, and ensuring safety. However, in extreme weather, such as during typhoons, the poles are easily damaged or collapsed by strong winds. Lowering the height can reduce the impact of strong winds to some extent. However, considering the different wind strengths, simply adjusting the height to deal with the wind will limit lighting and make it difficult to guarantee the service life. Therefore, an automatic lifting device for urban lighting poles is designed. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic lifting device for urban lighting poles. This device employs a three-tiered protective system, progressively activating the flexible assembly plate, dual-drive support rails, tilt and storage rack, and lifting frame under varying wind intensities. This addresses the adverse effects of different wind conditions. Furthermore, from preventing tipping and providing cushioning during use to reducing wind exposure area, to facilitating storage and transportation, it effectively reduces the probability of accidental damage to the light pole during its lifespan, thereby extending the overall service life of the device and reducing maintenance and replacement costs due to damage.

[0032] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. The various embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0033] Example 1

[0034] Please see Figures 1 to 12The present invention preferably provides the following technical solution: an automatic lifting device for urban lighting poles, comprising: a progressively lifting frame, a tilting and retracting frame, and a double-track reinforcement frame arranged sequentially from bottom to top, respectively used to achieve primary center of gravity lifting protection, secondary folding and retracting protection, and tertiary inward retraction reinforcement protection for the lamp body; the double-track reinforcement frame includes double drive rails and a flexible assembly plate installed on the double drive rails, wherein the flexible assembly plate can be detachably assembled with the lamp body. When encountering a weak wind, the flexible assembly plate can cause the lamp body to tilt with the wind, reducing the wind-exposed area of ​​the corresponding surface of the lamp body; when encountering a moderate to strong wind, the double drive rails cause the flexible assembly plate to retract inward, reinforcing the connection position between the flexible assembly plate and the pole, thereby reducing the risk of excessive swaying of the flexible assembly plate.

[0035] The progressively lifting frame, tilting and storing frame, and double-track reinforcing frame of this invention are arranged sequentially from bottom to top and together form a lamp post for lamp body assembly, such as... Figure 1-5 As shown, in order to enhance the protective performance of the light pole, especially its wind resistance, the application provides a three-level protective operation for the light body by means of a first-level center of gravity lifting method, a second-level folding storage method, and a third-level inward reinforcement method. The core advantage is that it improves the safety, portability, durability and adaptability of the light fixture in many aspects and at many levels, and actively responds to different strengths. It is worth mentioning that the application has a built-in wind speed sensor of the prior art, which can determine the wind speed threshold to realize the activation drive of the step-by-step lifting frame, the tilting storage frame and the double-track reinforcement frame.

[0036] First, when encountering strong winds of low intensity, the flexible assembly plate can cause the lamp body to tilt with the wind, thereby reducing the wind-exposed area of ​​the corresponding surface of the lamp body.

[0037] Secondly, when encountering strong winds of moderate to low intensity, the dual-drive support rails reinforce the connection between the flexible assembly plate and the flexible assembly plate by causing the flexible assembly plate to retract inward. This increases the rigidity of the retracted flexible assembly plate and prevents the flexible assembly plate and the lamp body from shifting, loosening, or even breaking due to excessive wind force.

[0038] Furthermore, when encountering moderate to strong winds, the tilting and retracting rack can fold down the originally vertical double-track reinforcement frame and its components and store them inside, significantly reducing the wind-exposed area.

[0039] When encountering strong winds, the step-by-step lifting frame operates, which is known to be one of the most effective means of preventing tipping. This greatly improves the stability of the light pole in severe weather conditions such as wind and rain, and reduces the risk of damage to the light pole itself, personal injury or other accidents caused by the tipping of the light body.

[0040] This application utilizes different structural designs based on wind speed to significantly improve the protective performance of the device, thereby enhancing its durability. The inward retraction, folding, and lifting of the light pole further reduce its size and improve portability. Meanwhile, the height adjustment feature of the progressively lifting frame further meets the different installation height requirements of the light body, expanding the applicability of the light pole.

[0041] Example 2

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

[0043] Combination Figure 8 , 9 As shown in Figure 10, it is known that the transmission seat 315 is slidably installed on one side of the assembly vertical plate 314 via the slide rail 3141 provided on the assembly vertical plate 314, and the trapezoidal seat 317 distributed on the other side is slidably installed on the transmission seat 315 via 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 extends and retracts, the synchronous and relative sliding process of the transmission seat 315 and the trapezoidal seat 317 can be realized. For details, please refer to the following text, which will not be repeated here.

[0044] Furthermore, the transmission components include a mounting block 320 fixed to the side of the mounting vertical plate 314 away from the slide rail 3141. The mounting block 320 and the transmission seat 315 are respectively fixed with opposing and staggered first transmission members 319 and second transmission members 316. The first transmission members 319 and second transmission members 316 have identical structures. The first transmission member 319 includes a transmission plate 3191 and a groove formed on the transmission plate 3191. The groove includes a straight groove 3192 and a recessed groove 3193 that are interconnected and communicate with each other. An extension plate 318 is fixed to the trapezoidal seat 317 near the second transmission member 316. The extension plate 318 is rotatably mounted with an extension rod 321 via a rotating shaft. The components also include a second roller 322 and a first roller 323 rotatably mounted at both ends of the extension rod 321. Wheels 323 are respectively placed inside the grooves where the second transmission member 316 and the first transmission member 319 are located; the lower part of the assembly vertical plate 314 is also provided with an electric telescopic rod 324 through the first fixing block. The electric telescopic rod 324 is fixedly connected to the lower part of the transmission seat 315 through the second fixing block 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 retraction process of the flexible assembly plate; when the electric telescopic rod 324 extends, the transmission seat 315 first slides up. 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 component 319 and the second transmission component 316 are respectively fixed on the mounting block 320 and the transmission seat 315 and are arranged in a staggered manner relative to each other, such as... Figure 8 , 9 As shown, the trapezoidal base 317 has a first roller 323 and a second roller 322 installed on its side wall via an extension plate 318 and an extension rod 321. When the electric telescopic rod 324 is in the... Figure 8 When the transmission seat 315 is pushed up, at this time, the second roller 322 is not in the groove 3193 where the second transmission member 316 is located and is rolling on the surface of the straight groove 3192. At this time, the transmission seat 315 moves up on its own first. 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 up synchronously to push the flexible assembly plate out further.

[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. 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, as... Figure 6 ,9 As shown in the diagram, the trapezoidal seat 317 is locked in position, while the transmission seat 315 continues to slide down relative to the trapezoidal seat 317, thereby placing the flexible assembly plate as... Figure 8 The state is further recessed to the interior of the protective structure formed by the assembly of vertical plate 314 and trapezoidal seat 317.

[0047] Furthermore, the flexible assembly plate includes a sleeve body composed 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 horizontal shafts 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 horizontal shafts 414 through hexagonal slots 416 opened thereon; wedge-shaped fixing blocks 417 are respectively fixed on both sides of the bottom of the rigid sleeve 413; and a trapezoidal transmission block 418 installed in the bottom of the rigid sleeve 413 and capable of horizontally limiting and sliding, wherein the trapezoidal transmission block 418 and the two wedge-shaped fixing blocks 417 on both sides respectively form limiting grooves, each limiting groove is provided with a ball 419, and the two 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 inside the sleeve composed of the flexible sleeve 411 and the rigid sleeve 413. Simultaneously, two transmission columns 415 fixed at the bottom of the assembly plate 412 are respectively sleeved on two horizontal shafts 414 fixed at the lower part of the rigid sleeve 413 through hexagonal slots 416. The two transmission columns 415 also contact the rolling balls 419 inside the two limiting slots. It is worth noting that the trapezoidal transmission block 418 can slide horizontally and limit its movement at the bottom of the rigid sleeve 413. Therefore, when the assembly plate 412 is subjected to a small-intensity wind, the two transmission columns 415 at the bottom of the assembly plate 412 can not only sway slightly on the two horizontal shafts 414, but also... Figure 12 When it shifts 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 groove formed in the middle of the trapezoidal seat 317; a clamping plate 420 slidably mounted on the surface of the trapezoidal seat 317; and a telescopic sleeve 421 fixed to the side wall of the rigid sleeve 413. The telescopic sleeve 421 is provided with a telescopic post 422, wherein the outer end of the telescopic post 422 passes through the through groove and is connected to a connecting sleeve 424 fixed to the side wall of the clamping plate 420; a spring 423 is sleeved on the outer wall of the telescopic post 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, this application provides a telescopic sleeve 421 on the side wall of the rigid sleeve 413. The telescopic sleeve 421 contains a telescopic post 422, the outer end of which is fixed to the connecting sleeve 424 on the side wall of the clamping plate 420. A spring 423 is provided in the middle of the post. Figure 11 As shown, when subjected to wind of a certain intensity, the electric telescopic rod 324 drives the flexible assembly plate to move downward as a whole. At this time, the clamping plate 420 can move downward on the surface of the trapezoidal seat 317. Since the transverse diameter of the trapezoidal seat 317 is as shown... Figure 9 As shown, the number of plates increases sequentially from top to bottom, thus pulling the clamping plate 420 apart from the rigid sleeve 413. At this time, through the action of the spring 423, the rigid sleeve 413 and the clamping plate 420 can clamp the trapezoidal seat 317, thereby strengthening the connection stability between the flexible assembly plate and the double drive support rail.

[0051] Example 3

[0052] In another embodiment of the present invention, the tilt storage rack includes a U-shaped frame 211 fixed to the lifting end of the step-by-step lifting frame, and transmission rail assemblies are symmetrically arranged on opposite sides of the U-shaped frame 211; each transmission cabinet assembly includes a vertical rail 214 fixed to the U-shaped frame 211, a first slider 215 slidably installed inside the vertical rail 214, and a horizontal rail 216 fixed on the first slider 215, wherein a support plate 312 is fixed to one end of the horizontal rail 216, a second slider 217 is arranged inside the horizontal rail 216, and an elongated groove 218 is opened on its top. The transmission block 219 is internally located in the long slot 218, and the vertical bar 220 is fixed to the top of the transmission block 219. The rack 221 is horizontally fixed to the top of the vertical bar 220. The pitch storage rack also includes a transmission shaft 313 and a connecting block 311 respectively set on the opposite surfaces of the two support plates 312. The transmission shaft 313 is rotatably installed with the two support plates 312, and its middle part is fixedly connected to the mounting vertical plate 314. Two gears 222 that mesh with the two racks 221 are fixed at both ends.

[0053] Furthermore, sprocket drive assemblies are symmetrically arranged on opposite sides of the U-shaped frame 211, respectively used to drive the two sets of drive rail assemblies; each set of sprocket drive assemblies includes four sprocket bodies 212 rotatably mounted on the inner wall of the U-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 into a vertical section on one side and an inclined upper section and a wave-shaped lower section on the other side; it also includes a first motor 223 disposed on the outer wall of the U-shaped frame 211, the output shaft of the first motor 223 passing through a through hole opened in the side wall of the U-shaped frame 211 and fixed to one of the sprocket bodies 212.

[0054] In this embodiment, the two sets of transmission rail assemblies are distributed opposite to each other, and the assembly vertical plate 314 equipped with the double track reinforcement frame can be rotatably installed with the two support plates 312 via the transmission shaft 313. The two support plates 312 are respectively fixed to one opposite end of the horizontal 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 mesh with the racks 221 where the two sets of transmission rail assemblies are located. When the two sets of transmission rail assemblies are running, the folding and storage process of the assembly vertical plate 314 can be realized.

[0055] Specific examples Figure 7 As shown, the vertical rails 214 and horizontal rails 216 of each group of transmission rail assemblies are arranged in a cross shape. The first slider 215 inside the horizontal rail 216 is fixed to the vertical rail 214. The second slider 217 inside the horizontal rail 216 is hinged to the chain 213 of the corresponding sprocket transmission assembly. Each chain 213 is divided into a vertical section on one side and an inclined upper section and a wave-shaped lower section on the other side.

[0056] First, the rotation direction of chain 213 in this application is as follows: Figure 7 The chain 213 deflects clockwise, so when the second slider 217 passes through its vertical section, the second slider 217 can drive the horizontal rail 216 and the first slider 215 connected to it to move upward inside the vertical rail 214. During this process, it can drive the assembly vertical plate 314 to move upward, realizing the assembly of the lamp body. Figure 7 As shown;

[0057] Subsequently, if a strong wind of a certain intensity is encountered, chain 213 will... Figure 7 If the rotation continues clockwise, the chain 213 causes the second slider 217 to move to the right inside the horizontal rail 216 while simultaneously driving the first slider 215 to move downwards on the vertical rail 214. During this process, as the second slider 217 drives the transmission block 219, rack 221, and gear 221 to move to the right and downwards, the two racks 221 can respectively drive the two meshing gears 222 to deflect clockwise, thereby causing the mounting vertical plate 314 to...

[0059] In another embodiment of the present invention, the step-by-step lifting frame includes a base plate 111, a first rod sleeve 112 disposed on the surface of the base plate 111, and a winding and unwinding roller; and a second rod sleeve 113, a third rod sleeve 114, and a fourth rod sleeve 115 disposed inside the first rod sleeve 112 and sequentially sleeved from bottom to top, with rectangular grooves 116 respectively opened on one side of the second rod sleeve 113, the third rod sleeve 114, and the fourth rod sleeve 115; it also includes a transmission roller frame and a pull rope 119 respectively disposed between the first rod sleeve 112 and the second rod sleeve 113, between the second rod sleeve 113 and the third rod sleeve 114, and between the third rod sleeve 114 and the fourth rod sleeve 115, wherein the pull rope 119 is disposed between the first rod sleeve 112 and the second rod sleeve 113. A pull rope 119 passes over the transmission roller on the first sleeve 112 and acts between the take-up / unwind roller and the bottom of the second sleeve 113. A pull rope 119 placed between the second sleeve 113 and the third sleeve 114 has one end connected to the transmission roller frame on the first sleeve 112 via the first connector 122, and the other end passes over the transmission roller on the second sleeve 113 and is fixed to the bottom of the third sleeve 114. A pull rope 119 placed between the third sleeve 114 and the fourth sleeve 115 has one end connected to the transmission roller frame on the second sleeve 113 via the second connector 123, and the other end passes over the transmission roller on the third sleeve 114 and is fixed to the bottom of the fourth sleeve 115.

[0060] like Figure 1-5 As shown, the first rod sleeve 112, the second rod sleeve 113, the third rod sleeve 114, and the fourth rod sleeve 115 are distributed sequentially from bottom to top and from outside to inside. The first rod sleeve 112, the second rod sleeve 113, and the third rod sleeve 114 are respectively provided with transmission rollers. The second rod sleeve 113, the third rod sleeve 114, and the fourth rod sleeve 115 are respectively connected to the take-up and release rollers, the transmission rollers provided on the second rod sleeve 113, and the transmission rollers provided on the third rod sleeve 114 through the pull rope 119.

[0061] Specifically, such as Figure 4 , 5 As shown, when the winding roller winds up the upper pull rope 119, the second sleeve 113 can be raised inside the first sleeve 112. At this time, due to the raising of the second sleeve 113, the transmission roller on the first sleeve 112 remains stationary. Therefore, when the second sleeve 113 drives the third sleeve 114 inside it to rise, one end of the pull rope 119 inside the third sleeve 114 is connected to the transmission roller on the first sleeve 112 and remains stationary. The other end can further pull the third sleeve 114 relative to the second sleeve 113 to rise further during the process of the third sleeve 114 following the second sleeve 113. Thus, the first sleeve 112, the second sleeve 113, the third sleeve 114 and the fourth sleeve 115 are raised step by step.

[0062] Furthermore, the transmission roller frame includes a U-shaped frame 117, with U-shaped grooves respectively formed at both ends of the U-shaped frame 117. Each U-shaped groove is rotatably mounted with a transmission wheel 118 via a pin. Figure 5 As shown.

[0063] Furthermore, the take-up and unwinding roller includes a motor base fixed to the surface of the base plate 111, on which a second motor 120 is mounted; and a roller body 121 fixed to the output end of the second motor 120, wherein a pull rope 119 placed between the first sleeve 112 and the second sleeve 113 is fixedly connected to the roller body 121, and the take-up and unwinding process of the pull rope 119 can be realized when the second motor 120 is driven to run.
