Description

Technical Field

[0001] This invention belongs to the field of lighting device technology, and specifically relates to a street light pole that is easy to maintain. Background Technology

[0002] Streetlight poles are vertical supporting steel structures that carry streetlights, cables, and maintenance electrical components in urban roads, parks, rural roads, scenic areas, and other lighting scenarios. They are the basic supporting facilities for outdoor road lighting systems, playing a core role in fixing lighting sources, laying power supply lines, and raising the lamps to achieve large-area uniform lighting. The main body of streetlight poles is mostly made of hot-dip galvanized steel pipes, aluminum alloys, stainless steel, etc., and undergoes bending and welding, overall hot-dip galvanizing for corrosion protection, and outdoor powder coating for rust prevention. According to the structure, they are divided into single-arm, double-arm, high and low arm, courtyard irregular shape, and integrated smart streetlight poles.

[0003] When carrying out high-altitude maintenance work on street light poles and their associated lighting accessories, workers need to carry various maintenance tools and replacement parts while climbing the poles. The extra weight changes the center of gravity of the workers, increasing the risk of imbalance and falls from heights, and making the work more difficult. At the same time, existing street light poles do not have dedicated storage structures for tools and accessories. Once operators reach the high-altitude work position, there is no reliable place to put things, making it inconvenient to retrieve and replace tools and accessories. This increases the difficulty and safety hazards of high-altitude street light maintenance work. Summary of the Invention

[0004] The purpose of this invention is to provide a street light pole with a simple structure and reasonable design that is easy to maintain in order to solve the above problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A light pole designed for easy maintenance includes a pole body. A power distribution box for distributing power is fixedly connected to the surface of the pole body. The power distribution box integrates a controller, including but not limited to a PLC or other control module. A support device is provided on one side of the pole body. The support device includes a support plate mounted on one side of the pole body as a platform. An outer frame is mounted on one side of the support plate. Assembly cavities are formed on the side surfaces of both the support plate and the outer frame. A connecting arm is rotatably connected to the inner wall of each assembly cavity. The connecting arm connects the outer frame and the support plate, allowing the outer frame to be unfolded or folded by an operator. A sliding connection is also provided to the inner wall of the assembly cavity. A positioning pin is fixedly connected to the assembly cavity by a spring. A square groove is opened on the side of the connecting arm facing the positioning pin, and the positioning pin is inserted into the inner wall of the square groove. A protective steel cable is installed between the pallet and the outer frame. The protective steel cable is made of materials such as 316 stainless steel to adapt to long-term outdoor use. The cooperation between the protective steel cable and the outer frame can form a shielding structure above the pallet, thereby restricting the range of movement of tools and accessories placed on the pallet. A protective cover is fixedly connected to the distribution box and the pole. The protective cover can protect the folded load device and prevent the load device from being unfolded by non-operators.

[0007] As a further optimization of the present invention, a rotating shaft is rotatably connected to the side of the connecting arm away from the outer frame. A limiter is fixedly connected to the end of the rotating shaft away from the connecting arm. The rotating shaft can support the position of the limiter and guide the rotation direction of the limiter. A load-bearing plate is slidably sleeved on the surface of the rotating shaft. A top rod is fixedly connected to both ends of the load-bearing plate. The load-bearing plate can synchronously drive the top rods on both sides to move. A pressure sleeve adapted to the limiter is fixedly connected to the surface of the load-bearing plate.

[0008] As a further optimization of the present invention, the end of the positioning pin away from the spring is an insertion part, which is square in shape. Under the action of the spring, the positioning pin can be inserted into the square groove and lock the position of the connecting arm so that the connecting arm supports the unfolded outer frame. The end of the assembly cavity near the connecting arm is a square cavity that adapts to the insertion part of the positioning pin.

[0009] As a further optimization of the present invention, the limiter is provided with a boss on the side near the rotating shaft. The boss is V-shaped. The surface of the pressure sleeve is provided with a groove that matches the boss. The boss is inserted into the groove. The top rod slides through the connecting arm. The cooperation between the pressure sleeve and the boss allows the operator to lock the position of the load-bearing plate under the operator's operation when folding the outer frame later.

[0010] As a further optimization of the present invention, a connecting device is provided between the rod and the tray. The connecting device includes a connecting frame installed on one side of the rod. A strong magnet is fixedly connected to the inner wall of the connecting frame. A cover plate is fixedly connected to the inner wall of the connecting frame. The cooperation between the cover plate and the connecting frame can protect the strong magnet. A limiting shaft is rotatably connected to the inner wall of the connecting frame. A mounting frame is fixedly connected to the surface of the limiting shaft. The mounting frame is fixedly connected to the surface of the tray. The cooperation between the connecting frame, the limiting shaft, and the mounting frame allows the tray to rotate around the limiting shaft to change the folding state of the tray. A positioning frame is slidably connected to the inner wall of the mounting frame. A strong magnet adapted to the strong magnet is fixedly connected to the inner wall of the positioning frame.

[0011] As a further optimization of the present invention, the inner wall of the mounting frame is provided with a sliding groove, and a slider is fixedly connected to the side surface of the positioning frame. The slider is slidably connected to the sliding groove. The cooperation between the sliding groove and the slider can constrain the position of the positioning frame within the mounting frame and limit the moving distance of the mounting frame, so as to avoid the positioning frame from moving excessively or deviating when moving.

[0012] As a further optimization of the present invention, the side of the connecting frame away from the rod body is arc-shaped, the cover plate abuts against the surface of the first strong magnet, the positioning frame is inserted into the inner wall of the connecting frame, and the first strong magnet and the second strong magnet are magnetically connected. After the positioning frame is inserted into the connecting frame, the position of the mounting frame and the tray can be locked, so that the tray is kept in the unfolded state, so as to facilitate the operator to place tools and accessories.

[0013] As a further optimization of the present invention, an adjustment device is provided on one side of the rod. The adjustment device includes a guide frame fixed to the side of the rod. The connecting frame is slidably mounted on the guide frame. The guide frame can guide the movement direction of the connecting frame, thereby ensuring the stability of the connecting frame during movement. A guide component is provided at the upper end of the guide frame. A shell is fixedly connected to the side of the rod. A side cover is fixedly connected to the surface of the shell. A support shaft is rotatably connected to the shell and the side cover. A cable is fixedly connected between the support shaft and the connecting frame. When the operator rotates the support shaft, the support shaft winds the cable and pulls the connecting frame, thereby driving the supporting device to move along the vertical direction of the rod. A guide disc is fixedly connected to the surface of the support shaft. The guide disc is spiral-shaped and can guide the cable when the support shaft winds the cable, so that the cable can be distributed more evenly on the support shaft. A motor is fixedly connected to the surface of the shell. The output end of the motor is fixedly connected to the support shaft.

[0014] As a further optimization of the present invention, the guiding assembly includes a guide wheel rotatably mounted inside a guide frame. Two guide rollers are rotatably connected inside the guide frame, distributed on both sides of the cable to ensure stable guidance of the cable. A bracket is fixedly connected to the back of the guide frame, and a second guide roller is rotatably connected to the bracket. A third guide roller is rotatably connected between the outer shell and the rod. The guide wheel, guide rollers one, two, and three are all in contact with the surface of the cable. The cooperation of the guide wheel, guide rollers one, two, and three can guide the cable when the support shaft winds the cable, avoiding the problem of accelerated wear caused by hard contact between the cable and different structures during movement.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. By using the support device and connecting device installed on the side of the pole, when operators carry out high-altitude maintenance work, they can quickly deploy the support device through the connecting device to build a stable platform on the side of the pole. Various maintenance tools and replacement parts can be placed stably on the platform. When not in use, it can be folded up and fitted to the pole, without occupying space or affecting the overall appearance and normal use of the street light. This avoids the problem that operators do not have a reliable place to put their items after arriving at the high-altitude work position, making it inconvenient to retrieve and replace tools and parts, which increases the difficulty of high-altitude maintenance work and increases safety hazards.

[0017] 2. By installing an adjustment device on the pole, operators can flexibly raise and lower the support device according to the actual height of the current maintenance point when carrying out high-altitude maintenance of street lights. This allows the platform for carrying tools and accessories to be precisely aligned with the working height, and tools and accessories can be placed nearby in a position that is easy for operators to access. This eliminates the need to repeatedly raise or bend over to retrieve tools or accessories, reducing the intensity of high-altitude operations and improving maintenance convenience.

A support device 5 is provided on one side of the pole body 1. The support device 5 includes a support plate 51 installed on one side of the pole body 1. An outer frame 53 is installed on one side of the support plate 51. Assembly cavities are formed on the side surfaces of both the support plate 51 and the outer frame 53. A connecting arm 52 is rotatably connected to the inner wall of the assembly cavity. The connecting arm 52 is used to connect the outer frame 53 and the support plate 51, so that the outer frame 53 can be changed to an unfolded or folded state by the operator. A positioning pin 55 is slidably connected to the inner wall of the assembly cavity. A spring 55 is fixedly connected between the positioning pin 55 and the assembly cavity. 6. A square groove is provided on the side of the connecting arm 52 facing the positioning pin 55. The positioning pin 55 is inserted into the inner wall of the square groove. A protective steel cable 54 is installed between the pallet 51 and the outer frame 53. The protective steel cable 54 is a flexible structure and is made of materials such as 316 stainless steel to adapt to long-term outdoor use. The cooperation between the protective steel cable 54 and the outer frame 53 can form a shielding structure above the pallet 51, thereby restricting the range of movement of tools and accessories placed on the pallet 51. A protective cover 8 is fixedly connected to the distribution box 2 and the pole 1. The upper and lower ends of the protective cover 8 are open to prevent rainwater from accumulating in the protected area of ​​the protective cover 8. The protective cover 8 can protect the folded support device 5 and prevent the support device 5 from being unfolded by non-operators. The distribution box 2, controller, monitoring probe 3 and LED light 4 are all existing technologies and will not be described in detail here.

[0035] Please see Figure 6 and Figure 7 A rotating shaft 57 is rotatably connected to the side of the connecting arm 52 away from the outer frame 53. A limiter 58 is fixedly connected to the end of the rotating shaft 57 away from the connecting arm 52. The rotating shaft 57 can support the position of the limiter 58 and guide the rotation direction of the limiter 58. A load plate 59 is slidably sleeved on the surface of the rotating shaft 57. A top rod 510 is fixedly connected to both ends of the load plate 59. The load plate 59 can synchronously drive the top rods 510 on both sides to move. A pressure sleeve 511 adapted to the limiter 58 is fixedly connected to the surface of the load plate 59.

[0036] Please see Figure 7The end of the positioning pin 55 away from the spring 56 is an insertion part, which is square. The end of the assembly cavity near the connecting arm 52 is a square cavity that adapts to the insertion part of the positioning pin 55, so as to guide the movement direction of the positioning pin 55. Under the action of the spring 56, the positioning pin 55 can be inserted into the square groove and lock the position of the connecting arm 52, so that the connecting arm 52 locks and supports the unfolded outer frame 53. The locking and unlocking structures such as the positioning pin 55, the spring 56, the load plate 59, and the top rod 510 can be selected in appropriate quantities according to actual requirements.

[0037] Please see Figure 8 The limiter 58 has a boss on the side near the rotating shaft 57. The boss is V-shaped. The surface of the pressure sleeve 511 has a groove that matches the boss. The boss is inserted into the groove. The top rod 510 slides through the connecting arm 52. The cooperation between the pressure sleeve 511 and the boss allows the operator to lock the position of the load plate 59 under the operator's operation when folding the outer frame 53 later.

[0038] Please see Figure 5 and Figure 9 A connecting device 6 is provided between the rod body 1 and the support plate 51. The connecting device 6 includes a connecting frame 61 installed on one side of the rod body 1. A strong magnet 62 is fixedly connected to the inner wall of the connecting frame 61. A cover plate 63 is fixedly connected to the inner wall of the connecting frame 61. The cooperation between the cover plate 63 and the connecting frame 61 can protect the strong magnet 62. A limiting shaft 65 is rotatably connected to the inner wall of the connecting frame 61. A mounting frame 64 is fixedly connected to the surface of the limiting shaft 65. The mounting frame 64 is fixedly connected to the surface of the support plate 51. The cooperation between the connecting frame 61, the limiting shaft 65 and the mounting frame 64 allows the support plate 51 to rotate around the limiting shaft 65 to change the folding state of the support plate 51. A positioning frame 68 is slidably connected to the inner wall of the mounting frame 64. A strong magnet 69 adapted to the strong magnet 62 is fixedly connected to the inner wall of the positioning frame 68.

[0039] Please see Figure 9 The inner wall of the mounting bracket 64 is provided with a sliding groove 66, and the side surface of the positioning bracket 68 is fixedly connected with a slider 67. The slider 67 is slidably connected to the sliding groove 66. The cooperation between the sliding groove 66 and the slider 67 can constrain the position of the positioning bracket 68 within the mounting bracket 64 and limit the movement distance of the mounting bracket 64 to prevent the positioning bracket 68 from moving excessively or deviating when moving.

[0040] Please see Figures 9-11The connecting frame 61 is arc-shaped on the side away from the rod 1. The cover plate 63 abuts against the surface of the strong magnet 62. The positioning frame 68 is inserted into the inner wall of the connecting frame 61. The strong magnet 62 and the strong magnet 69 are magnetically connected. After the positioning frame 68 is inserted into the connecting frame 61, the position of the mounting frame 64 and the tray 51 can be locked, so that the tray 51 is kept in the unfolded state, so as to facilitate the operator to place tools and accessories.

[0041] Please see Figure 4 , Figure 5 , Figure 12 , Figure 13 and Figure 14 An adjustment device 7 is provided on one side of the rod body 1. The adjustment device 7 includes a guide frame 71 fixed to the side of the rod body 1. A connecting frame 61 is slidably mounted on the guide frame 71. The guide frame 71 can guide the movement direction of the connecting frame 61, thereby ensuring the stability of the connecting frame 61 during movement. A guide assembly 72 is provided at the upper end of the guide frame 71. A housing 74 is fixedly connected to the side of the rod body 1. A side cover 75 is fixedly connected to the surface of the housing 74. A support shaft 76 is rotatably connected to the housing 74 and the side cover 75. A cable 73 is fixedly connected between the support shaft 76 and the connecting frame 61. The cable 73 is made of materials such as 316 stainless steel to adapt to long-term outdoor use. In the external operating environment, when the operator rotates the support shaft 76, the support shaft 76 winds the cable 73 and pulls the connecting frame 61, thereby driving the support device 5 to move in the vertical direction of the rod 1. A guide disc 77 is fixedly connected to the surface of the support shaft 76. The guide disc 77 is spiral in shape and can guide the cable 73 when the support shaft 76 winds the cable 73, so that the cable 73 can be distributed more evenly on the support shaft 76. A motor 78 is fixedly connected to the surface of the outer shell 74. The output end of the motor 78 is fixedly connected to the support shaft 76. The motor 78 is a self-locking motor 78, including but not limited to servo motors, etc. The motor 78 is existing technology and will not be described in detail here.

[0042] Please see Figure 12 and Figure 13The guide assembly 72 includes a guide wheel 721 rotatably mounted inside the guide frame 71. A guide roller 722 is rotatably connected inside the guide frame 71. There are two guide rollers 722, which are distributed on both sides of the cable 73 to ensure stable guidance of the cable 73. A bracket 723 is fixedly connected to the back of the guide frame 71. A guide roller 724 is rotatably connected to the bracket 723. A guide roller 725 is rotatably connected between the outer shell 74 and the rod 1. The guide wheel 721, guide roller 722, guide roller 724 and guide roller 725 are all in contact with the surface of the cable 73. The cooperation of the guide wheel 721, guide roller 722, guide roller 724 and guide roller 725 can guide the cable 73 when the support shaft 76 winds the cable 73, avoiding the problem of accelerated wear caused by hard contact between the cable 73 and different structures during movement.

[0043] It should be noted that when performing maintenance work on the pole body 1, monitoring probe 3, or LED light 4, the motor 78 is started by the switch in the distribution box 2. The motor 78, together with the support shaft 76, winds the cable 73. The cable 73 pulls the connecting frame 61. The connecting frame 61, together with the guide frame 71, moves the supporting device 5 out of the protective cover 8. When the supporting device 5 is completely moved out of the protective cover 8, the outer frame 53 is pulled outward. The outer frame 53 is guided and unfolded by the connecting arm 52. The protective steel cable 54 is simultaneously pulled open to form a side protective barrier. When the outer frame 53 is fully unfolded to a horizontal state, the square groove of the connecting arm 52 rotates to align with the positioning pin 55. The positioning pin 55 loses the squeezing constraint of the side wall of the connecting arm 52. The spring 56 rebounds and pushes the positioning pin 55 into the square groove, automatically locking the position of the connecting arm 52 and completing the unfolding and locking of the outer frame 53.

[0044] Then, the tray 51 is flipped upwards. The tray 51 rotates around the limiting shaft 65 of the connecting frame 61 via the mounting frame 64. When the tray 51 is flipped to the horizontal unfolded state, the positioning frame 68 in the mounting frame 64 is aligned with the insertion position of the connecting frame 61. The strong magnet 62 attracts the strong magnet 69, which drives the positioning frame 68 to slide into the interior of the connecting frame 61, realizing the magnetic self-locking of the tray 51 in the horizontal state. The tray 51 and the unfolded outer frame 53 together form an expanded bearing platform, completing the full unfolding operation of the carrying device 5.

[0045] After the support platform is unfolded, the maintenance toolbox and spare parts are placed on the pallet 51; the motor 78 is started, and the motor 78 rotates the support shaft 76 under the control of the controller. When the support shaft 76 rotates, the cable 73 is evenly wound around the guide plate 77. After the cable 73 is guided in multiple directions by the guide wheel 721, guide roller 1 722, guide roller 2 724, and guide roller 3 725, it smoothly pulls the connecting frame 61 to slide vertically upward along the guide frame 71, thereby lifting the entire support device 5.

[0046] When motor 78 is turned off, motor 78 locks the support shaft 76 to rotate, and the support device 5 is stably locked at the target height. Maintenance personnel can then climb up and use the platform to carry out maintenance work on streetlights and monitoring probes 3. Disassembled parts can be temporarily placed on the support plate 51.

[0047] After the maintenance work is completed and the operator returns to the ground, the motor 78 is started to reverse, the support shaft 76 releases the cable 73, and the connecting frame 61 slides smoothly down the guide frame 71 along the support device 5 and the weight of the tool. After it reaches the lowest position, the motor 78 is turned off.

[0048] After removing the tools and accessories from the tray 51, pull the positioning frame 68 outward to disengage the second strong magnet 69 from the first strong magnet 62. The positioning frame 68 then exits the connecting frame 61 and is unlocked. Flip the tray 51 downward to complete the folding and resetting process. Next, press the load plate 59, and at the same time, the boss disengages from the groove. Push the positioning pin 55 inward through the top rod 510 to compress the first spring 56, causing the positioning pin 55 to disengage from the square groove of the connecting arm 52 and unlock the outer frame 53. Rotate the limiter 58 to move the boss to the end face of the pressure sleeve 511, keeping the load plate 59 in the unlocked state. Then, flip the outer frame 53 inward to complete the entire storage operation. In actual operation, the entire unfolding, adjustment, and storage process can be completed in just a few steps.

[0049] With the support device 5 and connecting device 6 installed on the side of the pole 1, when operators carry out high-altitude maintenance work, they can quickly unfold the support device 5 through the connecting device 6 to build a stable platform on the side of the pole. Various maintenance tools and replacement parts can be placed stably on the platform. When not in use, it can be folded up and attached to the pole 1, without occupying space or affecting the overall appearance and normal use of the street light. This avoids the problem that there is no reliable place to put things after the operators arrive at the high-altitude work position, making it inconvenient to retrieve and replace tools and parts, which increases the difficulty of high-altitude maintenance work and increases safety hazards.

[0050] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
