Description

Technical Field

[0001] This invention relates to the field of street light installation technology, and more specifically to a street light installation auxiliary device. Background Technology

[0002] Streetlights generally refer to the lighting fixtures within the road surface lighting range of traffic lighting. This includes not only sidewalk lights but also streetlights along both sides of the motor vehicle lanes. These lights are generally installed at a relatively high height, and the height of streetlights in the same area has a uniform specification, but they are generally over six meters. To facilitate the installation and maintenance of streetlights by streetlight management personnel, steps are usually installed on the streetlight poles, while streetlights without steps are installed or maintained using ladder trucks.

[0003] When streetlights are damaged during use, as they are extremely important public facilities for assisting nighttime driving, staff must promptly dismantle the damaged streetlights and install new ones. However, streetlights are generally quite large, and climbing up the poles via steps to operate them would be extremely dangerous. Therefore, ladder trucks are used in such cases. Current ladder trucks generally consist of two parts: a vehicle and a platform. The platform is then raised to the designated height using a lifting arm.

[0004] While existing aerial ladder trucks can assist workers in climbing, the platforms they transport are typically made up of multiple connecting booms, which are then linked by various hydraulic actuators. This necessitates complex control by workers when lifting the platform, requiring them to skillfully manage the actuators between the booms. This significantly increases the difficulty of training street light maintenance personnel. Furthermore, the large size of the booms in traditional aerial ladder trucks necessitates larger transport vehicles, which can easily cause road congestion during maintenance. Therefore, this invention proposes an auxiliary device for street light installation. Summary of the Invention

[0020] Beneficial effects

[0021] The technical solution provided by this invention has the following advantages compared with known public technologies:

[0022] 1. This invention is equipped with a drive mechanism. In addition to using only a single motor to drive the device, which makes it easier for operators to operate, the drive mechanism also allows multiple sleeves to unfold sequentially through the cooperation of the first magnet, the second magnet, the pressing rod, the locking block, the turntable, and the coil spring. This transfers part of the friction between the external and internal threads during the ascent to the locking block and the first magnet, effectively reducing the wear of the external and internal threads and increasing the service life of the device. At the same time, because the ascent structure can be folded up, the space occupied by this device is only slightly larger than that of a passenger basket. It can be put into use by simply placing it under the lamp post and occupying a small area, thus reducing the obstruction of traffic caused by street light maintenance.

[0023] 2. This invention is equipped with a clamping mechanism. After being raised, the clamping mechanism in this device will clamp onto the outside of the street light pole, creating a connection between the device and the pole. This not only prevents the pole from swaying under stress when installing large components such as lamp covers on it, but also improves the stability of the device itself through the cooperation of the pole groove, the concave surface of the carrying basket, and the clamping plate. Furthermore, this structure makes it easier for workers to find the placement position of the device more quickly, making the raised carrying basket position more convenient for workers to install the street light.

[0024] 3. The present invention is provided with a round rod, sleeve rods and insert rods on each sleeve rod. With the cooperation of these structures, the round rod is the last to rise when the basket is raised and the round rod is the first to retract when the basket is lowered. The other sleeve rods can also change from the outside to the inside when the basket is raised and from the inside to the outside when the basket is lowered. This ensures that the clamping action of the clamping plate occurs when the basket is raised to its highest point and makes contact with the clamping plate at the first moment when the basket is lowered. The design is ingenious. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] A street light installation auxiliary device, reference Figure 1-12 It includes a mobile seat 1, on which a passenger basket 2 is provided, which is used to carry street light management personnel;

[0041] The front wall of the passenger basket 2 has an entrance 36, and a movable door 37 is hinged to the lower part of the entrance 36. Multiple steps 38 are evenly fixed to the rear wall of the movable door 37. When the movable door 37 is opened, the steps 38 resemble a standard staircase, facilitating the movement of personnel. A groove 39 is provided on the lowest step 38, allowing personnel to pull up the movable door 37 after entering the passenger basket 2. A fixed frame 40 is fixed to one side of the front wall of the passenger basket 2. The fixed frame 40 has a U-shaped structure. A side plate 42 is elastically connected to the inner wall of the fixed frame 40 away from the movable door 37 via multiple return springs 41. Multiple baffles 43 are evenly fixed to the side wall of the side plate 42 near the movable door 37. The end of the baffle 43 near the movable door 37 has a sloping structure and penetrates the fixed frame 40. The inner wall extends to the outside. The baffle 43 is slidably connected to the fixed frame 40. The rear wall of the baffle 43 is pressed against the front wall of the movable door 37. When the front wall of the baffle 43 near the movable door 37 is pressed, it will drive the side plate 42 to retract into the fixed frame 40. Then the movable door 37 is embedded in the entrance 36. The baffle 43 will pop out and lock the movable door 37 under the action of the return spring 41. The top surface of the moving seat 1 is provided with a door groove 44 that is inserted and matched with the upper end of the movable door 37. The door groove 44 is used to limit the movable door 37 and provide support for it, preventing the movable door 37 from loosening due to long-term stepping. Two safety bars 49 are symmetrically fixed inside the man-carrying basket 2 near the bar groove 48. Workers can fix the safety rope to the safety bar 49 to achieve the protection effect after climbing.

[0042] Two rollers 46 are symmetrically rotatably connected to the outer walls of both sides of the mobile seat 1. Multiple fixing rings 47 are evenly fixed on the front wall of the mobile seat 1. The fixing rings 47 can be used as trailer rings or to help workers climb the mobile seat 1. A pole groove 48 is opened on the side of the mobile seat 1 near the clamping mechanism 13. The outer wall of the person-carrying basket 2 near the pole groove 48 has a semi-circular concave structure coaxial with the pole groove 48. The pole groove 48 and the concave surface of the person-carrying basket 2 are both for embedding the lamp pole of the street light. This is to facilitate the clamping mechanism 13 to clamp the lamp pole and to limit the position of the device so that the device is located in the most convenient place for workers to carry out street light installation operations.

[0043] The bottom surface of the passenger basket 2 is equipped with a drive mechanism 3, which includes a motor 4. The motor 4 is fixedly connected to the bottom surface of the passenger basket 2. The output end of the motor 4 is coaxially fixedly connected to a rotating shaft 5. Multiple sleeves 6 are coaxially arranged inside the rotating shaft 5. The dimensions of the multiple sleeves 6 increase sequentially from the inside to the outside. The relationship between any two adjacent sleeves 6 is similar to the relationship between any two adjacent rods in a multi-section telescopic rod. That is, the rotating shaft 5, the multiple sleeves 6, and the threaded rod 7 together constitute a multi-section telescopic rod that needs to be driven to extend and retract. The bottom surfaces of the multiple sleeves 6 and the bottom surface of the rotating shaft 5 are all located on the same plane. The bottom surface of the innermost sleeve 6 is coaxially equipped with a threaded rod 7. A shaft groove 45 is provided at a position relative to the rotating shaft 5. The lower end of the threaded rod 7 is connected and fixed to the bottom surface of the shaft groove 45. External threads 8 are provided on the outer walls of multiple sleeves 6. Internal threads 9 are provided on the inner walls of the rotating shaft 5 and multiple sleeves 6. The external threads 8 are threadedly connected to the internal threads 9 adjacent to their outer sides. The threaded rod 7 is threadedly connected to the innermost internal thread 9. Two locking blocks 10 are symmetrically and elastically connected to the upper ends of the other sleeves 6 except the outermost sleeve 6. Two block grooves 14 are provided at the upper ends of the threaded rod 7 and the upper ends of multiple sleeves 6 located on the inner side at positions relative to the locking blocks 10. The inner ends of the locking blocks 10 are elastically connected to the inner walls of the block grooves 14 through compression springs 15. The locking blocks 10 are located in the passenger basket 2. When not raised, it is compressed by the inner wall of the innermost sleeve 6 and stored in the block groove 14. The two locking blocks 10 are arranged in a centrally symmetrical structure. The outer ends of the top surfaces of the locking blocks 10 and the first magnet 11 are both inclined. A pressing rod 16 is slidably connected to the middle of the top surface of the through-hole 12. The upper and lower ends of the pressing rod 16 are both hemispherical structures. The outer ends of the locking blocks 10 and the first magnet 11 are pressed and engaged with the lower ends of the corresponding pressing rods 16. In order to better compress the pressing rods 16, the top inclined surfaces of the locking blocks 10 and the first magnet 11 are inclined on one side of the outer wall of the locking blocks 10. This inclined surface will be squeezed by the side wall of the through-hole 12 when the drive mechanism 3 retracts. The pressure allows the locking block 10 to retract into the slot 14, while the other side, corresponding to the inclined surface, remains a flat structure. This design is to prevent the locking block 10 from being squeezed into the slot 14 when the drive mechanism 3 raises the manned basket 2. The upper end of each sleeve 6 is symmetrically connected to two first magnets 11, and the lower part of each sleeve 6 is symmetrically provided with two through holes 12. The through holes 12 are respectively connected to the interior of the corresponding sleeve 6. The locking block 10 engages with its corresponding through hole 12. When the locking block 10 or the first magnet 11 is engaged in the through hole 12, the threaded rod 7 or the sleeve 6 connected to the first magnet 11 will be fixed together with the moving seat 1 and will not be able to rotate relative to it.

[0044] A groove 17 is provided on the upper part of the sleeve 6 relative to the position of the first magnet 11. The first magnet 11 is slidably connected to the groove 17. Two T-shaped blocks are symmetrically fixed on both sides of the first magnet 11. The inner wall of the groove 17 is provided with a T-shaped groove that slides with the T-shaped blocks. This restricts the position of the first magnet 11 to only move inward and outward and prevents it from detaching from the groove 17. A circular cavity 18 is provided between the two grooves 17. The circular cavity 18 is a T-shaped cylindrical structure that is smaller at the top and larger at the bottom. Two fixing plates 19 are symmetrically fixed on the top surface of the circular cavity 18. The fixing plates 19 are arc-shaped structures. A turntable 20 is provided at the lower part of the circular cavity 18. A fixing rod 21 is coaxially fixed on the top surface of the turntable 20. A coil spring 22 is sleeved on the fixing rod 21. The outer end of the coil spring 22 is connected and fixed to the inner wall of one of the fixing plates 19. This structure allows the turntable 20 to... The rotating disk 20 has four second magnets 23 fixed on its top surface in a ring-shaped, equally spaced structure. The S pole of the first magnet 11 faces the direction of the cavity 18. Two of the second magnets 23 are positioned opposite the slide groove 17 and their S poles face the direction of the slide groove 17. The inner walls of the sleeves 6 and the inner walls of the rotating shaft 5 are provided with fixing grooves 50 at positions opposite to the second magnets 23. The second magnets 23 are inserted into the corresponding fixing grooves 50. The two magnets are in a repulsive state with the first magnet 11. Therefore, the outer end of the first magnet 11 extends outside the slide groove 17 and is inserted into the fixing groove 50. In this way, under the action of the first magnet 11, the multiple sleeves 6 will be fixed to each other and fixed to the rotating shaft 5. When the motor 4 drives the rotating shaft 5 to rotate, the multiple sleeves 6 will also rotate.

[0045] The other two second magnets 23 are located on the outer sides of the two fixed plates 19, with their S poles facing the fixed plates 19. Multiple second magnets 23 slide in contact with the upper inner wall of the circular cavity 18 and the outer wall of the fixed plate 19. The upper end of the extrusion rod 16 extends through the bottom surface of the circular cavity 18 into its interior. An arc groove 24 is formed on the bottom surface of the turntable 20 relative to the upper end of the extrusion rod 16. The arc groove 24 has a quarter-circle arc structure, and the two arc grooves 24 are centrally symmetrical. The top surface of the arc groove 24 gradually rises from the end near the extrusion rod 16 to the end away from the extrusion rod 16. The upper end of the extrusion rod 16 is pressed against the top surface of the arc groove 24. When the extrusion rod 16 is pressed upwards by the clamping block 10, the extrusion rod 16 will pass through the arc groove 24. The structure of 4 causes the turntable 20 to rotate. Due to the design of the arc groove 24, the turntable 20 will rotate 90 degrees. In this way, the other two second magnets 23 will correspond to the inner ends of the two first magnets 11 respectively. Then, because the S poles of the other two magnets 11 are facing inward, their N poles will correspond to the S poles of the first magnets 11. Then, the first magnets 11 will be pulled inward by the attraction between them and the second magnets 23, and will be completely submerged in the slide groove 17 and no longer inserted into the fixed groove 50. In this way, the innermost sleeve 6 is no longer connected and fixed to the adjacent sleeve 6. Under the action of the locking block 10, the innermost sleeve 6 is now fixed to the moving seat 1. Thus, the motor 4 continues to drive the rotating shaft 5 to rotate. When in motion, the sleeve 6 adjacent to the innermost sleeve 6 will move upward along the threaded connection of the two sets of threads. At the start, because of the obstruction of the locking block 10, the pressing rod 16 will not fall, so the pressing rod 16 always keeps the position of the second magnet 23 in the rotated state. When the position of the locking block 10 on the innermost sleeve 6 corresponds to the position of the through hole 12 on the outer sleeve 6, the corresponding locking block 10 will lock the through hole 12. Then, the same action will be produced under the same principle. In this way, the manned basket 2 can be continuously raised by the drive of a motor 4. When descending, the locking block 10 will be squeezed into the block groove 14 first due to the inclined structure of the side wall. This design allows multiple openings with external threads 7 to be made. The sleeves 6 rise sequentially under the action of the threads. Because they need to overcome not only the friction between the threads but also gravity during the rising process, the wear between the threads will be more severe. With this design, the multiple sleeves 6 on the upper side can be connected by the second magnet 23. The force generated by the rotation will act on the second magnet 23, while the threaded rod 7 on the lower side and the sleeves 6 that have risen to their maximum extent will be fixed by the locking block 10. The force will act on the locking block 10, which effectively improves the service life of the two threaded structures. Compared with the unrestricted connection of multiple threaded columns, this method can maximize the use of the driving force of the motor 4, reduce energy consumption, and also reduce the operation difficulty of this device.

[0046] A clamping mechanism 13 is provided on one side of the bottom surface of the manned basket 2, and the clamping mechanism 13 clamps on the upper part of the street lamp pole. Four round rods 51 are respectively fixed at the four corners of the bottom surface of the manned basket 2, a plurality of sleeve rods 25 are sequentially sleeved outside the round rods 51, and the outermost sleeve rod 25 is inserted on the moving base 1. A through hole 26 is formed in the lower part of the inner wall of each of the remaining sleeve rods 25 except the outermost sleeve rod 25, the through hole 26 is in a cylindrical structure with a middle narrowed shape, an insertion rod 27 is arranged inside the through hole 26, the outer end of the insertion rod 27 is of a hemispherical structure and is in press fit with the edge of the open end of the sleeve rod 25 on its outer side, the inner end of the insertion rod 27 is of a T-shaped structure and extends through the round rod 51 into the sleeve rod 25, and the outer end of the insertion rod 27 is elastically connected with the inner wall of the through hole 26 through a first tension spring 28. When the plurality of sleeve rods 25 are retracted together, the first tension spring 28 will be in a stretched state. Slots 29 in insertion fit with the inner end of the insertion rod 27 are formed at the lower ends of the outer walls of the remaining sleeve rods 25 except the two outermost sleeve rods 25 and at the lower end of the outer wall of the round rod 51. Under such a structure, the second sleeve rod 25 from the outside to the inside is not restricted in the initial state, so it will be pulled out first. When the position of the insertion rod 27 is higher than the top surface of the outermost sleeve rod 25, the insertion rod 27 will move outward under the action of the first tension spring 28, so that the inner end of the insertion rod 27 will move out of its corresponding slot 29, the restriction on the sleeve rod 25 it restricts will be released, then the third sleeve rod 25 from the outside to the inside will be pulled out, and the subsequent operation follows the same principle. During retraction, due to the restriction between the outer end of the insertion rod 27 and the open end of the sleeve rod 25, and the plurality of first tension springs 28 are set to have sequentially increasing toughness from the inside to the outside, the round rod 51 will be retracted into the sleeve rods 25 first during retraction, and the plurality of sleeve rods 25 elastically connected with the insertion rod 27 will be sequentially retracted into the lower sleeve rods 25 from top to bottom, which avoids the problem that the insertion rod 27 moves inward first before the sleeve rod 25 is retracted, and prevents the device from jamming.

[0047] The clamping mechanism 13 includes two symmetrically arranged clamping plates 30, which are slidably connected to the bottom surface of the manned basket 2. The end of the clamping plate 30 away from the motor 4 has a quarter-circle structure. A compression pad 31 is fixedly provided on the inner wall of the clamping plate 30. A side groove 32 is opened on the inner wall of the clamping plate 30 near the motor 4. A second tension spring 33 is fixedly provided between the two side grooves 32. The second tension spring 33 is stretched in the initial state. The outer walls of the two innermost sleeve rods 25 on the side near the clamping plate 30 are hinged to the outer wall of the clamping plate 30. The two rotating rods 34 are arranged in a figure-eight structure with the upper part larger than the lower part. Under this structure, when the most When the inner sleeve rod 25 moves down, the rotating rod 34 tends to be flat, and the clamping plates 30 will move closer to each other and clamp the lamp post. With the compression pad 31, the clamping plates 30 can clamp the lamp post more firmly, thereby enhancing the stability of the lamp post and the device itself. When retracting, the round rod 51 is the first to be retracted, and the distance between the passenger basket 2 and the innermost sleeve rod 25 becomes smaller. Therefore, the clamping plates 30 will open first, preventing damage caused by the clamping plates 30 not opening when the device descends. Except for the innermost sleeve rod 25, the upper ends of the other sleeve rods 25 are provided with adaptation grooves 35 at the position relative to the rotating rod 34.

[0048] Working principle: Workers can connect an external traction rope to the fixing ring 47 of this device, and then use the traction rope to fix the moving seat 1 to the traction vehicle. Then, the vehicle can move this device to the lamp post of the street light to be replaced. The size of this device is comparable to the climbing platform of a traditional ladder truck. Both the moving seat 1 and the personnel basket 2 have recesses that match the lamp post, so this device can be placed next to the street light and occupy a small space. Afterwards, workers can climb to the top of the moving seat 1 through the fixing ring 47, and then use the steps 38 on the movable door 37 to enter the personnel basket 2. Workers can use a safety rope to connect themselves to the safety bar 49 of this device to ensure personal safety after climbing. Then, the movable door 37 is pulled up by the pull groove 39, and the driving mechanism 3 is operated to raise the personnel basket 2 to the street light position. After being raised, the clamping mechanism 13 in this device will clamp onto the outside of the street light pole, so that the device and the lamp post are connected. This can prevent the lamp post from shaking under force when installing the lamp cover and also improve the stability of the device.
