Description

Technical Field

[0001] This invention relates to the field of hoisting sling technology, specifically to an adaptive protective hoisting device for street light pole slings that prevents scratches. Background Technology

[0002] Lifting slings are specialized flexible load-bearing components used in lifting operations to bind, suspend, and pull heavy objects. They are often used in conjunction with cranes and hoists to effectively distribute stress, stably support heavy objects, prevent slippage and swaying during lifting, and ensure operational safety. They are widely used in engineering infrastructure, factory handling, equipment installation, warehousing and logistics, and are an indispensable basic safety accessory for lifting operations.

[0003] When installing streetlight poles, slings are often used for hoisting. Traditional construction methods involve directly binding and wrapping the slings around the upper outer wall of the streetlight pole for lifting. This process easily abrades the surface of the streetlight pole, and there is a risk of the pole slipping during hoisting. Existing technologies, such as CN202220537395.9, which describes a streetlight hoisting device for partial installation on the streetlight pole, still have the following problems:

[0004] 1) The hoisting system is only compatible with a small range of street light pole diameters, making it difficult to adapt to street light poles with larger or more varied diameters;

[0005] 2) The existing abutment part is a direct connection, which can easily cause surface friction during hoisting, thus wearing down the surface of the street light pole;

[0006] To address this, we propose an adaptive protective lifting device for street light pole slings that prevents scratches. Summary of the Invention

[0007] (a) Technical problems to be solved

[0008] To address the shortcomings of existing technologies, this invention provides an adaptive protective lifting device for street light pole slings that prevents scratches. This solves the problems of traditional construction methods that involve directly binding and wrapping slings around the upper outer wall of the street light pole for lifting operations, which easily abrades the surface of the street light pole during operation and poses a risk of slippage during the lifting process.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, the present invention provides the following technical solution: a scratch-resistant adaptive protective hoisting device for streetlight poles, comprising a hoisting rope, the lower end of which is provided with a hoisting assembly. The hoisting assembly includes a first clamp and a second clamp, which are arranged in a clamping pattern during use, both being semi-circular arcs, enclosing the streetlight pole body. Anti-slip pads are installed on the inner sides of both the first and second clamps. A retaining rod is alternately installed on the side of the first and second clamps that is close to each other. A stop bar is installed at one end of the retaining rod on the second clamp, supporting the hoisting rope. Sleeve blocks are installed on the side of the first and second clamps that are far apart from each other, through which the hoisting rope alternately passes. The lifting rope is equipped with a limiting block, which abuts against a sleeve block on the first clamping plate. A locking mechanism is provided below the second clamping plate, and a stabilizing component is installed at the upper end of the lifting rope. The first and second clamping plates are interlocked and surround the light pole through staggered clamping rods. With the cooperation of the lifting rope and the sleeve block, it can adaptively adapt to the upper dimensions of street light poles with different outer diameters and tapered structures that are thinner at the top and thicker at the bottom. It has a good fit and strong versatility. At the same time, anti-slip pads are provided on the inner side of the clamping plates. During hoisting, the clamping plates and the pole body are flexibly fitted, avoiding direct hard friction and compression of the outer wall of the street light pole by the lifting rope. This effectively prevents scratches, indentations and surface damage to the pole body paint, protects the appearance of the street light pole and the integrity of the anti-corrosion coating, and is suitable for hoisting operations of various types of street light poles.

[0011] Preferably, the locking mechanism includes a carrier plate installed below the second clamping plate. Two guide wheels are rotatably connected to the surface of the carrier plate. The center of each guide wheel is recessed inward. The lifting rope passes through the two guide wheels and is adapted to the recessed area of ​​the guide wheels. The locking mechanism utilizes the guide wheels, ratchet, and control rod to rotate the torsion block, which drives the guide wheels to rotate in one direction and tightens the lifting rope, realizing automatic clamping and positioning of the clamping plate. The recessed area of ​​the guide wheel is provided with a circumferential array of protruding teeth, which can bite the lifting rope and greatly reduce the risk of slippage and loosening of the lifting rope. The stop bar provides support and limit for the lifting rope, further improving the stability of the clamping structure. It is not easy to shift or slip during the lifting process, and the operation is highly safe.

[0012] Preferably, an "L"-shaped positioning frame is installed on the side of the carrier plate near the guide wheel, one end of the positioning frame extends to the front of one of the guide wheels, and a ratchet is installed on the side of the positioning frame away from the carrier plate. A control rod is installed inside the ratchet, the control rod passes through the positioning frame and is connected to the axis of one of the guide wheels.

[0013] Preferably, a torsion block is installed at the end of the control rod away from the carrier plate. The side wall of the torsion block is provided with anti-slip grooves. Rotating the torsion block drives the guide wheel to rotate in one direction through the control rod, which can tighten the lifting rope. The clamping rods on the first clamping plate and the second clamping plate are interlocked to surround the street light pole and form a tight connection. Through two sets of lifting components, two areas on the upper part of the street light pole are positioned simultaneously, which effectively reduces the possibility of the street light pole becoming loose and ensures the safety of the lifting process.

[0014] Preferably, the guide wheel recess area has multiple sets of protruding teeth arranged in a circumferential array. By embedding the protruding teeth into the lifting rope, the probability of the lifting rope slipping is reduced. The lifting rope is passed through the recess areas of the two guide wheels and adapted to fit them. By rotating the torsion block, one of the guide wheels is driven by the control rod to rotate unidirectionally with the ratchet. The protruding teeth of the circumferential array in the guide wheel recess bite the lifting rope, and the lifting rope is gradually wound and tightened. This causes the first clamp and the second clamp to continuously hug the street light pole inward, achieving adaptive fitting and locking, and preventing the clamps from loosening or shifting during the hoisting process.

[0015] Preferably, there are two sets of lifting ropes and lifting components. The two sets of lifting ropes and lifting components are stacked in an alternating manner. The two sets of lifting ropes and lifting components are arranged in an alternating manner to surround and position two areas on the upper part of the street light pole. The force is evenly distributed, which effectively suppresses the swaying and tilting of the light pole during the lifting process, avoids the risk of tipping due to unbalanced force on one side, and ensures the stability of the entire process of lifting, erecting and positioning.

[0016] Preferably, the stabilizing component includes a mounting plate located above the suspension rope. A pull block is installed at the upper end of the suspension rope. A threaded cylinder is rotatably connected to the inner wall of the mounting plate. A threaded rod is installed at the upper end of the pull block, and the threaded rod is threaded into the threaded cylinder. A lifting ring is installed at the middle of the upper end of the mounting plate. The top stabilizing component can be rotated and adjusted by the threaded cylinder, threaded rod, and adjusting sleeve to finely adjust the tension height of the two sets of suspension ropes, thereby adjusting the suspension ropes on both sides to a uniform tension. The adjusting sleeve and the end face of the retaining ring are larger than the diameter of the position hole to form an axial limit, preventing the threaded cylinder from coming out. The adjustment stroke is stable and reliable, and the posture of the street light pole can be accurately corrected, so that it remains vertical during the hoisting process, facilitating precise alignment and installation.

[0017] Preferably, the pull block is truncated cone-shaped, with its outer diameter gradually decreasing from top to bottom. Two sliding rods are mirror-mounted on the upper end of the pull block, and the sliding rods are slidably connected to the inner wall of the mounting plate. Limiting plates are installed on the upper ends of the sliding rods and threaded rods, and the sliding rods are slidably engaged with guide holes opened in the mounting plate to provide radial guidance for the threaded rods and pull block, preventing deflection and jamming during the adjustment process. The limiting plates, together with the retaining rings, form bidirectional limiting, ensuring smooth operation and reliable positioning of the adjustment structure. It is not prone to loosening or failure after long-term use and has a long service life.

[0018] Preferably, there are two threaded cylinders and two threaded rods, which are mirror images of each other on both sides of the lifting ring. The upper end of the lifting rope is connected to a stabilizing component. The lifting ring is used to connect to external lifting equipment for lifting. Rotating the adjusting sleeve can drive the threaded cylinder to rotate. Through the threaded transmission of the threaded cylinder and the threaded rod, the extension height of the threaded rod is adjusted, thereby adjusting the tension of the two sets of lifting ropes respectively, adjusting the lifting ropes on both sides to a uniform tension, correcting the posture of the street light pole, and ensuring that the light pole is always vertically suspended. The end face size of the adjusting sleeve and the retaining ring at the end closest to each other is larger than the diameter of the position hole, forming an axial anti-disengagement limit to prevent the threaded cylinder from coming out and failing. The limiting plate limits the stroke of the sliding rod and the threaded rod to ensure a smooth and stable leveling process, ensuring that the posture of the street light pole is stable, safe and reliable throughout the entire process of lifting, transporting and installing.

[0019] Preferably, an adjusting sleeve is installed at the upper end of the threaded cylinder, and a retaining ring is installed at the lower end of the threaded cylinder. The end face dimensions of the adjusting sleeve and the retaining ring at their respective close ends are both larger than the diameter of the position hole. Rotating the adjusting sleeve can drive the threaded cylinder to rotate, thereby adjusting the height of the threaded rod and adjusting both sets of suspension ropes to a taut state to ensure that the street light pole is in a stable and vertical state during hoisting.

[0020] An installation method for a scratch-resistant adaptive protective lifting device for street light pole slings includes the following steps:

[0021] Step 1: Lay the protective cloth flat on the ground, place the street light pole on its side on the protective cloth, and use the flange plate at the end to tilt the whole thing and make the street light pole tilt and hang in the air.

[0022] Step 2: Place the two sets of hoisting components on the upper part of the street light pole, and use the first and second clamps, which are arranged in a mirror shape and are semi-circular arcs, to surround and fit against the outer wall of the street light pole, with the anti-slip pads on the inside facing the street light pole.

[0023] Step 3: The hoisting rope alternately passes through the outer sleeve block of the first clamping plate and the second clamping plate, and the limiting block on the hoisting rope abuts against the sleeve block;

[0024] The hoisting rope shall wrap around the first and second clamps at least once and abut against the side rails of the second clamp.

[0025] Tighten the suspension rope to make the anti-slip mat press against the outer wall of the street light pole;

[0026] Step 4: Pass the end of the suspension rope through the recessed area of ​​the two guide wheels and fit it snugly.

[0027] Step 5: After releasing the ratchet restriction, rotate the torsion block, which drives one of the guide wheels and the ratchet to rotate via the control lever. The convex teeth of the inner circumferential array of the guide wheel engage the suspension rope, gradually winding and tightening the suspension rope to ensure that the first clamp and the second clamp continuously hug the street light pole inward, achieving adaptive fitting and locking; rotate until the control lever can no longer be rotated, and lock the ratchet to prevent rotation.

[0028] Step 6: Hoist and install a single set of street light poles. After installation, release the ratchet restraint, rotate the control lever in the opposite direction to remove the end of the hoisting rope, and then pull the hoisting rope to detach from each sleeve block in sequence. Release the clamps of the first and second clamps so that the overall structure is detached from the street light pole, thus completing the installation of the street light pole.

[0029] In summary, the technical effects and advantages of this invention are as follows:

[0030] 1. The first and second clamping plates of this invention interlock and surround the light pole through staggered clamping rods. With the cooperation of the hoisting rope and the sleeve block, it can adaptively adapt to the upper dimensions of street light poles with different outer diameters and tapered structures that are thinner at the top and thicker at the bottom. It has good clamping fit and strong versatility. At the same time, the inner side of the clamping plate is provided with anti-slip pads. During hoisting, the clamping plate and the pole body are flexibly fitted together, avoiding direct hard friction and compression of the outer wall of the street light pole by the hoisting rope. This effectively prevents scratches, indentations and surface damage to the pole body paint, protects the appearance of the street light pole and the integrity of the anti-corrosion coating, and is suitable for hoisting operations of various types of street light poles.

[0031] 2. The locking mechanism of the present invention utilizes a guide wheel, a ratchet, and a control rod. Rotating the torsion block drives the guide wheel to rotate in one direction and tighten the hoisting rope, thereby achieving automatic clamping and positioning of the clamping plate. The recessed area of ​​the guide wheel is provided with a circumferential array of protruding teeth, which can bite the hoisting rope and greatly reduce the risk of the hoisting rope slipping or loosening. The stop bar provides support and limit for the hoisting rope, further improving the stability of the clamping structure. It is not easy to shift or slip during the hoisting process, and the operation is highly safe.

[0032] 3. This invention uses two sets of lifting ropes and lifting components arranged in an alternating manner, and simultaneously surrounds and positions two areas on the upper part of the street light pole, so that the force is evenly distributed, effectively suppressing the swaying and tilting of the light pole during the lifting process, avoiding the risk of tipping due to unbalanced force on one side, and ensuring the stability of the entire process of lifting, erecting and positioning.

[0033] 4. The present invention uses a top stabilizing component that is adjusted by rotating a threaded cylinder, a threaded rod, and an adjusting sleeve. The tension height of the two sets of suspension ropes can be finely adjusted separately, and the suspension ropes on both sides can be adjusted to a uniform tension. The adjusting sleeve and the end face of the retaining ring are larger than the diameter of the position hole to form an axial limit, preventing the threaded cylinder from coming out. The adjustment stroke is stable and reliable, and the posture of the street light pole can be accurately corrected, so that it remains vertical during the hoisting process, which is convenient for accurate alignment and installation.

[0034] 5. This invention uses a sliding fit between the slide rod and the inner wall of the mounting plate to form a radial guide for the threaded rod and the pull block, avoiding deflection and jamming during the adjustment process. The limiting plate and the retaining ring form a bidirectional limit, ensuring smooth operation and reliable positioning of the adjustment structure. It is not easy to loosen or fail after long-term use and has a long service life. Attached Figure Description

[0045] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] refer to Figures 1-7The diagram illustrates an adaptive protective lifting device for scratch-resistant streetlight pole slings, comprising a sling 1. A lifting assembly 2 is mounted at the lower end of the sling 1. The lifting assembly 2 includes a first clamping plate 21 and a second clamping plate 22, which are mirror images of each other and are both semi-circular in shape. Anti-slip pads 23 are installed on the inner sides of both the first clamping plate 21 and the second clamping plate 22. A retaining rod 24 is alternately installed on the side of the first clamping plate 21 and the second clamping plate 22 where they are close to each other. A stop bar 25 is installed at one end of the retaining rod 24 on the second clamping plate 22, providing support for the sling 1. Sleeve blocks 27 are installed on the side of the first clamping plate 21 and the second clamping plate 22 where they are far apart. The sling 1 alternately passes through the sleeve blocks 27. Limiting blocks 2 are installed on the sling 1. 6. The limiting block 26 abuts against the sleeve block 27 on the first clamping plate 21. A locking mechanism is provided below the second clamping plate 22. A stabilizing component 3 is installed at the upper end of the lifting rope 1. The first clamping plate 21 and the second clamping plate 22 are interlocked and surround the lamp post by staggered clamping rods 24. With the cooperation of the lifting rope 1 and the sleeve block 27, it can adapt to the upper size of street lamp posts with different outer diameters and tapered structures with a thinner upper part and a thicker lower part. It has a good fit and strong versatility. At the same time, the inner side of the clamping plate is provided with anti-slip pads 23. During hoisting, the clamping plate and the pole body are flexibly fitted, avoiding the lifting rope 1 from directly and hard rubbing and squeezing the outer wall of the street lamp post. It effectively prevents scratches, indentations and surface damage to the paint surface of the pole body, protects the appearance of the street lamp post and the integrity of the anti-corrosion coating, and is suitable for hoisting operations of various types of street lamp posts.

[0047] The locking mechanism includes a carrier plate 28 installed below the second clamping plate 22. Two guide wheels 210 are rotatably connected to the surface of the carrier plate 28. The center of the guide wheel 210 is recessed inward. The lifting rope 1 passes through the two guide wheels 210 and is adapted to the recessed area 215 of the guide wheel 210. The locking mechanism uses the guide wheel 210, ratchet 212 and control rod 214 to cooperate. Rotating the torsion block 213 can drive the guide wheel 210 to rotate in one direction and tighten the lifting rope 1, so as to realize the automatic clamping and positioning of the clamping plate. The recessed area 215 of the guide wheel 210 is provided with a circumferential array of protruding teeth 211, which can bite the lifting rope 1, greatly reducing the risk of slippage and loosening of the lifting rope 1. The stop bar 25 provides support and limit for the lifting rope 1, further improving the stability of the clamping structure. It is not easy to shift or slip during the lifting process, and the operation is highly safe.

[0048] An "L"-shaped positioning frame 29 is installed on the side of the carrier plate 28 near the guide wheel 210. One end of the positioning frame 29 extends to the front of one of the guide wheels 210. A ratchet 212 is installed on the side of the positioning frame 29 away from the carrier plate 28. A control lever 214 is installed inside the ratchet 212. The control lever 214 passes through the positioning frame 29 and is connected to the axis of one of the guide wheels 210.

[0049] Among them, a torsion block 213 is installed at the end of the control rod 214 away from the carrier plate 28. The side wall of the torsion block 213 is provided with anti-slip grooves. Rotating the torsion block 213 drives the guide wheel 210 to rotate in one direction through the control rod 214, which can tighten the hoisting rope 1. The first clamping plate 21 and the second clamping plate 22 are interlocked with the holding rod 24 to surround the street light pole and form a tight connection. Through the two sets of hoisting components 2, the two areas on the upper part of the street light pole are positioned at the same time, which effectively reduces the possibility of the street light pole loosening and ensures the safety of the hoisting process.

[0050] The guide wheel 210 has a circumferential array of multiple sets of protruding teeth 211 in the recessed area 215. The protruding teeth 211 are embedded in the lifting rope 1 to reduce the probability of the lifting rope 1 slipping. The lifting rope 1 is passed through the recessed areas 215 of the two guide wheels 210 and fits and conforms to them. The torsion block 213 is rotated, and the control rod 214 drives one of the guide wheels 210 to rotate in one direction with the ratchet 212. The protruding teeth 211 in the circumferential array of the recessed area of ​​the guide wheel 210 bite the lifting rope 1 and gradually wind and tighten the lifting rope 1. This makes the first clamp 21 and the second clamp 22 continuously hug the street light pole inward, achieving adaptive fitting and locking, and preventing the clamps from loosening or shifting during the hoisting process.

[0051] The system consists of two sets of hoisting ropes 1 and two sets of hoisting components 2. The two sets of hoisting ropes 1 and hoisting components 2 are stacked in an alternating manner. The two sets of hoisting ropes 1 and hoisting components 2 are arranged in an alternating manner to surround and position two areas on the upper part of the street light pole. The force is evenly distributed, which effectively suppresses the swaying and tilting of the light pole during hoisting and avoids the risk of tipping over due to imbalance of force on one side. This ensures that the entire process of hoisting, erecting, and positioning is stable.

[0052] The stabilizing component 3 includes a mounting plate 31 located above the suspension rope 1. A pull block 32 is installed at the upper end of the suspension rope 1. A threaded cylinder 37 is rotatably connected to the inner wall of the mounting plate 31. A threaded rod 33 is installed at the upper end of the pull block 32 and is threaded into the threaded cylinder 37. A lifting ring 36 is installed at the middle of the upper end of the mounting plate 31. The top stabilizing component 3 can be adjusted by rotating the threaded cylinder 37, the threaded rod 33, and the adjusting sleeve 38 to finely adjust the tension height of the two sets of suspension ropes 1. This allows the suspension ropes 1 on both sides to be adjusted to a uniform tension. The adjusting sleeve 38 and the retaining ring 39 have an axial limit formed by the end face size being larger than the diameter of the position hole, preventing the threaded cylinder 37 from coming out. The adjustment stroke is stable and reliable, and the posture of the street light pole can be accurately corrected, ensuring that it remains vertical during the hoisting process and facilitating precise alignment and installation.

[0053] The pull block 32 is truncated cone-shaped, with its outer diameter gradually decreasing from top to bottom. Two slide rods 34 are mirror-mounted on the upper end of the pull block 32. The slide rods 34 are slidably connected to the inner wall of the mounting plate 31. A limit plate 35 is installed on the upper end of the slide rods 34 and the threaded rod 33. The slide rods 34 are slidably engaged with the guide holes opened in the mounting plate 31, forming a radial guide for the threaded rod 33 and the pull block 32, preventing deflection and jamming during the adjustment process. The limit plate 35, together with the retaining ring 39, forms a bidirectional limit, ensuring smooth operation and reliable positioning of the adjustment structure. It is not easy to loosen or fail after long-term use and has a long service life.

[0054] The system includes two threaded cylinders 37 and two threaded rods 33, which are mirror images of each other on both sides of the lifting ring 36. The upper end of the lifting rope 1 is connected to the stabilizing component 3. The lifting ring 36 is used for lifting with external lifting equipment. Rotating the adjusting sleeve 38 can drive the threaded cylinder 37 to rotate. Through the threaded transmission between the threaded cylinder 37 and the threaded rod 33, the extension height of the threaded rod 33 is adjusted, thereby adjusting the tension of the two sets of lifting ropes 1. The lifting ropes 1 on both sides are adjusted to a uniform tension state, correcting the posture of the street light pole and ensuring that the light pole is always vertically suspended. The end face size of the adjusting sleeve 38 and the retaining ring 39 is larger than the diameter of the position hole, forming an axial anti-detachment limit to prevent the threaded cylinder 37 from coming off and failing. The limiting plate 35 limits the travel of the sliding rod 34 and the threaded rod 33 to ensure a smooth and stable leveling process, ensuring that the posture of the street light pole is stable, safe and reliable throughout the entire process of lifting, transporting and installing.

[0055] The upper end of the threaded cylinder 37 is equipped with an adjusting sleeve 38, and the lower end of the threaded cylinder 37 is equipped with a retaining ring 39. The end face dimensions of the adjusting sleeve 38 and the retaining ring 39 at their respective close ends are both larger than the diameter of the position hole. Rotating the adjusting sleeve 38 can drive the threaded cylinder 37 to rotate, thereby adjusting the height of the threaded rod 33 and adjusting both sets of suspension ropes 1 to a taut state to ensure that the street light pole is in a stable and vertical state during hoisting.

[0056] Installation method of the present invention:

[0057] Step 1: Lay the protective cloth flat on the ground, place the street light pole on its side on the protective cloth, and use the flange plate at the end to tilt the whole thing and make the street light pole tilt and hang in the air.

[0058] Step 2: During the hoisting operation, the two sets of hoisting components 2 are respectively placed on the upper part of the street light pole. The first clamping plate 21 and the second clamping plate 22, which are arranged in a mirror shape and are semi-circular arc, are used to surround and fit against the outer wall of the street light pole. The anti-slip pads 23 set on the inner side of the clamping plates are in direct flexible contact with the pole body to avoid the hoisting rope 1 directly rubbing and squeezing the light pole, thus playing a protective role against scratches and indentations.

[0059] Step 3: The hoisting rope 1 alternately passes through the sleeve block 27 on the outside of the first clamping plate 21 and the second clamping plate 22. The limiting block 26 on the hoisting rope 1 abuts against the sleeve block 27 to form an axial limit on the hoisting assembly 2, so as to prevent the clamping plate from sliding along the hoisting rope 1 at will during the operation.

[0060] Step 4: Pass the suspension rope 1 through the recessed area 215 of the two guide wheels 210 and fit it to fit;

[0061] Step 5: Release the ratchet 212 restriction and separate the pawl 216 from the ratchet, allowing the ratchet to rotate; rotate the torsion block 213, and through the control lever 214 drive one of the guide wheels 210 to rotate unidirectionally with the ratchet 212. The protruding teeth 211 of the inner circumferential array of the guide wheel 210 engage with the lifting rope 1, gradually winding and tightening the lifting rope 1, so that the first clamp 21 and the second clamp 22 continuously hug the street light pole inward, achieving adaptive fitting and locking, and preventing the clamps from loosening or shifting during the hoisting process;

[0062] The device is equipped with two sets of lifting ropes 1 and lifting components 2, arranged in a staggered and overlapping manner. This allows for simultaneous and synchronized positioning of two areas on the upper part of the streetlight pole, ensuring even force distribution and effectively reducing the risk of the pole loosening or tipping due to unilateral stress, thus improving overall lifting stability. The lifting ropes 1 wrap around the first clamping plate 21 and the second clamping plate 22 at least once, and abut against the side retaining strips 25 of the second clamping plate 22. The ratchet is locked, with the pawl 216 engaging with it to lock the ratchet and prevent rotation. The pawl... Figure 8 As shown, the pawl shaft is connected to the positioning frame and rotates on the positioning frame. A fixing plate 217 is installed on the pawl shaft and is fixedly connected to the positioning frame. A drive motor 218 is installed on the fixing plate 217. The drive motor 218 has a stop self-locking function and drives the pawl to separate from the ratchet when working.

[0063] Step 6: The upper end of the lifting rope 1 is connected to the stabilizing component 3. The lifting ring 36 is used for external lifting equipment. Rotating the adjusting sleeve 38 can drive the threaded cylinder 37 to rotate. Through the threaded transmission between the threaded cylinder 37 and the threaded rod 33, the extension height of the threaded rod 33 is adjusted, thereby adjusting the tension of the two sets of lifting ropes 1 respectively. The lifting ropes 1 on both sides are adjusted to a uniform tension state, correcting the posture of the street light pole, so that the light pole is always kept vertically suspended. The end face size of the adjusting sleeve 38 and the retaining ring 39 is larger than the diameter of the position hole, forming an axial anti-detachment limit to prevent the threaded cylinder 37 from coming out and failing. The limiting plate 35 limits the stroke of the sliding rod 34 and the threaded rod 33 to ensure that the leveling process is smooth and stable, and to ensure that the posture of the street light pole is stable, safe and reliable throughout the entire process of lifting, transporting and installing.
