Description

Technical Field

[0001] This invention relates to the field of lighting equipment technology, and in particular to a street light pole with a quick-change street light head. Background Technology

[0002] Streetlights are lighting fixtures that provide illumination to roads. They generally refer to lighting fixtures within the road surface lighting range in traffic lighting. Streetlights are widely used in various places that require lighting.

[0003] Modern city roads cannot function without streetlights, especially at night when pedestrians need illumination. After prolonged use, some streetlight heads become damaged, requiring aerial work platforms to transport people to the top of the streetlight pole to remove the damaged head for replacement. This process is slow and inconvenient. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a street light pole for quick replacement of street light heads, which solves the technical problem of slow street light head replacement speed.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0008] This invention provides a street light pole for quick replacement of street light heads, comprising a lower section of the pole vertically supported on the ground, an upper section of the pole rotatably connected to the top of the lower section, and a mounting bracket disposed on the top of the upper section for mounting the street light head. The top of the lower section is rotatably connected to the middle of the upper section. A steel wire rope is disposed at the bottom side of the upper section, and a fixed pulley is rotatably disposed at the bottom side of the lower section. The steel wire rope is wound around the fixed pulley. Slowly rotating the fixed pulley releases the steel wire rope and causes the upper section to rotate from a vertical to an inclined position.

[0009] This invention proposes a streetlight pole for quick replacement of streetlight heads. The streetlight pole is divided into two parts: a lower section is vertically fixed to the ground, while an upper section is rotatably connected to the top of the lower section. When a streetlight head needs replacement, the upper section can be rotated to an inclined or horizontal position for easy replacement on the mounting bracket. However, due to the greater mass of the upper section, rotation can cause it to rotate rapidly, potentially leading to damage and safety issues. This invention addresses this by connecting a steel wire rope to the bottom of the upper section and installing a fixed pulley on the side of the lower section. The other end of the steel wire rope is fixed to the side of the pulley and winds around it as the pulley rotates. This steel wire rope limits the rotation of the upper section, allowing for slow rotation of the pulley and thus the upper section to rotate more slowly, making the process more convenient and safer.

[0010] Optionally, a speed reducer is arranged on the side end of the lower section of the lamp post on one side of the fixed pulley to limit the rotational speed of the fixed pulley.

[0011] By installing a speed reducer on the side of the lower section of the light pole, the rotation of the fixed pulley is restricted, making the rotation of the fixed pulley slower and thus making the process of replacing the street light head more convenient and safer.

[0012] Optionally, the reducer includes a rotating seat disposed on the side end of the lower section of the light pole and located on both sides of the fixed pulley, a speed reduction plate rotatably disposed on the rotating seat at the end away from the lower section of the light pole, and a speed reduction rubber sheet disposed on the speed reduction plate near the end face of the lower section of the light pole. One end of the speed reduction plate is suspended on the side of the fixed pulley away from the lower section of the light pole, and the speed reduction rubber sheet rotates with the speed reduction plate and abuts against the fixed pulley.

[0013] With the support of the rotating seat, the speed reduction plate and the speed reduction rubber plate are located on the side of the fixed pulley away from the lower section of the light pole. At this time, the speed reduction plate can be pressed on the side of the fixed pulley, so that the speed reduction rubber plate is pressed against the fixed pulley, allowing the fixed pulley to rotate at a slower speed, which is safer and more convenient. At the same time, the whole process is very easy to operate.

[0014] Optionally, the deceleration rubber sheet abuts against one end of the fixed pulley, which is an inclined deceleration end face, and the inclination direction of the deceleration end face is opposite to the rotation direction of the fixed pulley.

[0015] The end face of the deceleration rubber sheet that abuts against the fixed pulley is set in an inclined direction, and the inclined direction of the deceleration rubber sheet is opposite to the rotation direction of the fixed pulley. This allows the deceleration rubber sheet to gradually increase its contact area with the fixed pulley as the abutting force increases, thereby making the deceleration effect of the deceleration rubber sheet on the fixed pulley more controllable and convenient.

[0016] Optionally, the end face of the speed reducer away from the speed reducer rubber sheet is provided with multiple mutually limiting strips at an angle, and the mutually limiting strips on the two speed reducers are arranged facing each other and interlocked.

[0017] When the deceleration rubber plate is pressed against the fixed pulley, as the upper section of the lamp post rotates from a vertical to a horizontal position, the driving force of the fixed pulley will increase. At this time, the fixed pulley will apply a large force to the two sets of reducers in a direction away from each other. If the force received is too large, it can easily cause the reducers to loosen. In this solution, mutual limiting strips are set on one end face of the deceleration plate, so that the mutual limiting strips on the two deceleration plates are interlocked. This allows the two sets of mutual limiting strips to interact when the two deceleration plates are subjected to forces moving away from each other, thus making the two deceleration plates more firmly maintained in their positions and safer.

[0018] Optionally, the lower section of the lamp post is horizontally slidably provided with a limiting plate that drives the two sets of reducers to simultaneously press against and restrict the rotation of the fixed pulley. The end of the mutual limiting strip away from the reducer is rotatably provided with a roller. One end face of the limiting plate abuts against the roller. The rollers on the two sets of mutual limiting strips roll in opposite directions as the limiting plate moves.

[0019] By rotating the connecting roller at the end of the interlocking strip away from the speed reducer, when the street light head needs to be moved, the limiting plate can be slid horizontally so that the limiting plate abuts against the roller on the interlocking strip. Continuing to move the limiting plate, the roller rolls against one end of the limiting plate. At this time, the two sets of interlocking strips are inserted deeper into each other, and the speed reduction rubber plates of the two sets of speed reducers will gradually press against the fixed pulley, thereby reducing speed. This scheme allows the two sets of speed reducers to be controlled together by a single limiting plate, which is more convenient.

[0020] Optionally, a driven gear is coaxially arranged on the shaft of the fixed pulley, and a set of torque transmission gears is rotatably embedded inside the lower section of the lamp post. One gear in the torque transmission gear set meshes with the driven gear. A rotating handle for driving the torque transmission gear set is provided on the side of the lower section of the lamp post away from the fixed pulley. The rotating handle is detachably connected to the torque transmission gear set.

[0021] After the street light head is replaced, the upper section of the light pole needs to be rotated to a vertical position. At this time, the steel wire rope needs to be rotated and wound up to the fixed pulley. In this solution, a rotating handle is connected to the other end of the lower section of the light pole. By rotating the handle, the torque transmission gear set inside the lower section of the light pole is rotated, which in turn drives the driven gear to rotate, and finally drives the fixed pulley to rotate, so as to complete the winding of the steel wire rope. At the same time, the upper section of the light pole can be rotated to a vertical position manually. When the fixed pulley rotates to extend the steel wire rope, the internal torque transmission gear set can also apply a certain resistance to the rotation of the fixed pulley to cooperate with the use of the reducer, which is more convenient.

[0022] Optionally, the upper section of the light pole includes a first pole located at the top and vertically oriented, a second pole vertically disposed at the lower end of the first pole, and a third pole vertically disposed at the end of the second pole away from the first pole. The third pole is parallel to the first pole, the second pole is rotatably connected to the top of the lower section of the light pole, the first pole is coaxial with the lower section of the light pole, and the third pole abuts against and is detachably fixed to the side end of the lower section of the light pole.

[0023] By dividing the upper section of the light pole into three parts, the second pole is rotatably connected to the top of the lower section of the light pole, the first pole is connected to the top of the lower section of the light pole, thus forming a complete street light pole. The third pole can reduce the impact on the normal operation of the fixed pulley and the reducer, and can also balance the gravity of the first pole when it rotates, making the entire upper section of the light pole rotate more smoothly.

[0024] Optionally, a fixing member is provided at the lower end of the lower section of the lamp post away from the fixed pulley. The fixing member includes a first fixing plate horizontally fixed to the side end of the lower section of the lamp post and abutting against the lower end of the third pole, and a second fixing plate rotatably connected to the end of the first fixing plate away from the lower section of the lamp post. The rotation axis of the second fixing plate is horizontal, and the second fixing plate abuts against and is fixed to the side end of the third pole away from the lower section of the lamp post by bolts.

[0025] When the upper section of the light pole is rotated to a vertical position, the first fixing plate abuts against the lower end of the third pole. Then, the second fixing plate is rotated to a vertical position, abutting against the side end of the third pole. The third pole and the second fixing plate are then fixed together with bolts, thus limiting the position of the third pole and fixing the entire upper section of the light pole. When it is necessary to replace the light head, simply loosen the bolts and rotate the second fixing plate to a vertical downward position, at which point the upper section of the light pole can be rotated, making it more convenient.

[0026] Optionally, the rotating handle abuts against the same side end of the third rod and the lower section of the lamp post and is fixed by bolts.

[0027] The third pole and the lower section of the light pole are fixed by turning the handle. When the light head needs to be replaced, the handle can be removed and the replacement can be carried out. After the replacement is completed, the wire rope is wound up by turning the fixed pulley by turning the handle. Finally, the handle is fixed to the side of the third pole and the lower section of the light pole, which is more convenient.

[0028] (III) Beneficial Effects

[0029] The beneficial effects of this invention are as follows: The streetlight pole with quick-change streetlight head allows for easy replacement of the streetlight head by simply rotating the upper section of the pole to an inclined or horizontal position. However, due to the large mass of the upper section, rotating it would cause it to rotate rapidly, potentially leading to damage and safety issues. This invention connects a steel wire rope to the bottom of the upper section of the pole and installs a fixed pulley on the side of the lower section. The other end of the steel wire rope is fixed to the side of the pulley and winds around it as the pulley rotates. This steel wire rope limits the rotation of the upper section of the pole, allowing for slow rotation of the pulley when the streetlight head needs to be replaced, thus making the process more convenient and safer.

[0036] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] The street light pole for quick replacement of street light heads proposed in this invention allows for easy replacement of street light heads simply by rotating the upper section of the pole to an inclined or horizontal position. However, due to the significant weight of the upper section, rotation can cause it to rotate rapidly, potentially leading to damage and safety issues. This invention addresses this by connecting a steel wire rope to the bottom of the upper section and installing a fixed pulley on the side of the lower section. The other end of the steel wire rope is fixed to the pulley and winds around it as the pulley rotates. This steel wire rope limits the rotation of the upper section, allowing for slow rotation of the pulley and thus making the upper section of the pole more convenient and safer when replacing the street light head.

[0038] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0039] Reference Figure 1 and Figure 2 A street light pole for quick replacement of street light heads includes a lower section light pole 1 vertically supported and fixed to the ground, an upper section light pole 2 rotatably connected to the top of the lower section light pole 1, and a mounting base 3 fixed to the top of the upper section light pole 2 by bolts for mounting street light heads.

[0040] The top of the lower section lamp post 1 is integrally and parallelly provided with two parallel connecting plates 11. The two connecting plates 11 are arranged at intervals and form a rotating slot 12 between the two connecting plates 11. The upper section lamp post 2 includes a first rod 21 located at the top and vertically oriented, a second rod 22 vertically arranged at the lower end of the first rod 21, and a third rod 23 vertically arranged at the end of the second rod 22 away from the first rod 21. The third rod 23 is parallel to the first rod 21. The second rod 22 is inserted into the rotating slot 12 and is rotatably connected to the two connecting plates 11 by a rotating shaft. The first rod 21 is coaxial with the lower section lamp post 1. The third rod 23 abuts against and is fixed to the side end of the lower section lamp post 1. The rotation position of the second rod 22 is located at the upper side of the rotating slot 12, so that the upper section lamp post 2 can rotate normally.

[0041] The bottom side of the third pole 23 is fixed with a steel wire rope 4 by bolts. The bottom side of the lower section of the light pole 1 is rotatably connected to a fixed pulley 13 by a rotating shaft. The rotating shaft of the fixed pulley 13 is horizontal. The other end of the steel wire rope 4 is fixed to the side of the fixed pulley 13 by bolts and wrapped around the circumference of the fixed pulley 13, so that when the upper section of the light pole 2 needs to be rotated, the fixed pulley 13 needs to be rotated to gradually release the steel wire rope 4.

[0042] See Figure 3 and Figure 4 A speed reducer 14 is arranged on the side end of the lower section of the lamp post 1 to limit the rotational speed of the fixed pulley 13. The speed reducer 14 includes a rotating seat 141 fixed to the side end of the lower section of the lamp post 1 by bolts and located on the upper and lower sides of the fixed pulley 13, a speed reduction plate 142 rotatably connected to the rotating seat 141 at the end away from the lower section of the lamp post 1 by a rotating shaft, and a speed reduction rubber sheet 143 bonded to the end face of the speed reduction plate 142 near the lower section of the lamp post 1. One end of the speed reduction plate 142 is suspended on the side of the fixed pulley 13 away from the lower section of the lamp post 1. The speed reduction rubber sheet 143 rotates with the speed reduction plate 142 and abuts against the end face of the fixed pulley 13, thereby reducing the speed of the fixed pulley 13.

[0043] The deceleration rubber sheet 143 abuts against the fixed pulley 13 at one end, which is an inclined deceleration end face 1431. The inclination direction of the deceleration end face 1431 is opposite to the rotation direction of the fixed pulley 13. When the deceleration rubber sheet 143 is pressed against the fixed pulley 13, the contact area between the deceleration rubber sheet 143 and the fixed pulley 13 can be gradually increased with the pressing force, thereby making the deceleration effect of the deceleration rubber sheet 143 on the fixed pulley 13 controllable.

[0044] Multiple mutually limiting strips 1421 are welded at an angle to the end face of the speed reducer 142 away from the speed reducer rubber sheet 143. The multiple mutually limiting strips 1421 are arranged at intervals. The mutually limiting strips 1421 on the two speed reducers 142 are arranged facing each other and interlocked. The mutually limiting strips 1421 on the two speed reducers 142 are interlocked, so that when the two speed reducers 142 are subjected to forces moving away from each other, the two sets of mutually limiting strips 1421 can interact with each other, so that the two speed reducers 142 can be more firmly maintained in their own positions.

[0045] A sliding sleeve 15 is horizontally bolted to the side of the lower light pole 1 furthest from the third pole 23. A limiting rod 151 is horizontally slidably inserted into the sliding sleeve 15. A limiting plate 152 is bolted to the end of the limiting rod 151 near the fixed pulley 13. The limiting plate 152 is parallel to the fixed pulley 13 and located on the side of the fixed pulley 13 furthest from the lower light pole 1. The limiting plate 152 slides horizontally with the limiting rod 151. A roller 1422 is rotatably mounted on the end of the mutual limiting insert 1421 furthest from the deceleration plate 142 via a rotating shaft. One end face of the positioning plate 152 abuts against the roller 1422. The rollers 1422 on the two sets of mutual limiting strips 1421 roll in opposite directions as the limiting plate 152 moves to the lower section of the lamp post 1, thereby driving the two sets of mutual limiting strips 1421 to interlock. The two sets of mutual limiting strips 1421 interlock deeper, and the deceleration rubber plates 143 of the two sets of reducers 14 will gradually press against the fixed pulley 13 to decelerate. Thus, the two sets of reducers 14 can be controlled by a single limiting plate 152, which is more convenient.

[0046] A driven gear 131 is coaxially keyed to the shaft of the fixed pulley 13. A set of torque transmission gears 16 is rotatably embedded inside the lower section of the lamp post 1. One gear in the torque transmission gear set 16 meshes with the driven gear 131. A rotating handle 17 is inserted at the end of the lower section of the lamp post 1 away from the fixed pulley 13 to drive the torque transmission gear set 16 to rotate. By rotating the handle 17, the torque transmission gear set 16 inside the lower section of the lamp post 1 is driven to rotate, which in turn drives the driven gear 131 to rotate, and finally drives the fixed pulley 13 to rotate, so as to complete the winding of the wire rope 4. At the same time, it can be used to manually rotate the upper section of the lamp post 2 to a vertical position. When the fixed pulley 13 rotates to extend the wire rope 4, the torque transmission gear set 16 inside can also apply a certain resistance to the rotation of the fixed pulley 13 to cooperate with the use of the reducer 14.

[0047] See Figure 2 and Figure 4 After the handle 17 is disassembled, it can be directly attached to the same side of the third pole 23 and the lower section of the lamp post 1 and fixed with bolts.

[0048] See Figure 1 A fixing member 18 is provided at the lower end of the lower section of the lamp post 1 away from the fixed pulley 13. The fixing member 18 includes a first fixing plate 181 horizontally welded to the side end of the lower section of the lamp post 1 and abutting against the lower end of the third rod 23, and a second fixing plate 182 rotatably connected to the end of the first fixing plate 181 away from the lower section of the lamp post 1 via a rotating shaft. The rotating shaft of the second fixing plate 182 is horizontal. The second fixing plate 182 abuts against and is fixed to the side end of the third rod 23 away from the lower section of the lamp post 1 by bolts.
