Description

Technical Field

[0001] This invention relates to the field of aerial work platform technology, and in particular to an aerial work platform for ultra-high voltage transmission line engineering. Background Technology

[0002] In the 21st century, developing clean energy, addressing environmental issues, responding to climate change, and pursuing sustainable development have become a global consensus. As a crucial link in energy supply, the power grid plays a vital role in solving these problems. The power industry is the lifeblood of the national economy, playing a vital role in my country's economic development, national security, social stability, and quality of life. With the continuous development of the world economy and the ongoing progress of human civilization, energy demand continues to grow, environmental protection issues are becoming increasingly severe, and people have higher and higher requirements for the power grid. Power grid construction is facing unprecedented challenges, while its construction and maintenance equipment also face enormous challenges and significant opportunities.

[0003] In existing UHV transmission line projects, maintenance and repair work typically involves workers walking along the transmission lines or using simple suspended pulleys to move along them. While these pulleys are simple in structure and lightweight, they generally suffer from inherent drawbacks such as insufficient stability and difficulty in adjusting the working height. This not only limits their adaptability to different environments but also poses significant safety risks to workers at height. Therefore, this invention proposes an aerial work platform for UHV transmission line projects to address the aforementioned problems. Summary of the Invention

[0004] The purpose of this application is to provide an aerial work platform for ultra-high voltage transmission line engineering, in order to solve the inherent defects of the pulleys mentioned in the background art, which, although simple in structure and lightweight, generally suffer from insufficient stability and difficulty in adjusting the working height. This not only limits their adaptability to different environments, but also brings significant safety risks to personnel working at height.

[0005] To achieve the above objectives, this application provides the following technical solution: an aerial work platform for ultra-high voltage transmission line engineering, comprising:

[0006] The base has a moving mechanism installed on its top. The moving mechanism includes four brackets, four guide wheels, four auxiliary wheels, two steel cables, and four drive motors. The brackets are fixedly installed on the top of the base, and the guide wheels and auxiliary wheels are rotatably connected to the brackets.

[0007] The stabilizing mechanism is used to stabilize the position of the base.

[0008] Lifting mechanism, used to adjust the height of staff;

[0009] Support structure, used to support the height of the staff;

[0010] Safety agencies are responsible for ensuring the safety of their staff.

[0011] There are two sets of stabilizing mechanisms. The stabilizing mechanism works in conjunction with the support frame and steel cable. The lifting mechanism and support mechanism work in conjunction with the base. The safety mechanism works in conjunction with the lifting mechanism.

[0012] By integrating a moving mechanism, a stabilizing mechanism, a lifting mechanism, a supporting mechanism, and a safety mechanism, a multifunctional composite system is constructed using the above structure. The moving mechanism enables the platform to move along the power transmission line, the stabilizing mechanism ensures overall stability during movement and operation, the lifting and supporting mechanisms enable flexible adjustment and reliable locking of the working height, and the safety mechanism provides direct protection for personnel. This system comprehensively solves the problems of insufficient stability, difficulty in height adjustment, and poor safety of traditional suspended trolleys.

[0013] Preferably, the stabilizing mechanism includes: two bonding frames, a connecting rod, and two first electric push rods;

[0014] The bonding frame is fixedly installed on the top of the connecting rod, and the bonding frame slides in contact with the steel cable. The first electric push rod is fixedly connected to the bracket, and the output shaft of the first electric push rod is fixedly connected to the connecting rod.

[0015] Furthermore, the stabilizing mechanism drives the connecting rod and the bonding frame through the first electric push rod, so that the bonding frame can be tightly pressed onto the steel cable, increasing the contact area and friction between the platform and the load-bearing steel cable, effectively suppressing the swaying and sliding of the platform under wind or operating load, and significantly improving the overall stability and safety during high-altitude operations.

[0016] Preferably, the lifting mechanism includes: a platform, a guardrail, a frame door, two support rods, two suspension ropes, two winding rollers, two winding frames, and two winding motors;

[0017] The platform is slidably connected to the inside of four supports. The guardrail is fixedly installed on the top of the platform. The frame door is installed on the platform and the guardrail. Two support rods are fixedly installed on the top of the platform. Two suspension ropes are fixedly installed on the top of the guardrail. The suspension ropes pass through the support rods and are wound around the take-up roller. The take-up roller is rotatably connected to the take-up frame. The take-up frame is fixedly installed on the top of the base. The take-up motor is fixedly installed on the take-up frame. The output shaft of the take-up motor is fixedly connected to the take-up roller.

[0018] Furthermore, the lifting mechanism controls the winding roller to wind and unwind the hoisting rope via a winding motor, thereby smoothly raising or lowering the platform with guardrails. This enables precise electric adjustment of the workers' working height, allowing the platform to adapt to maintenance work needs at different heights and replacing the limitations of traditional methods that require climbing or have difficulty adjusting the height.

[0019] Preferably, the support mechanism includes: four positioning rods, four positioning frames, two connecting plates, two driving plates, a control plate, a second electric push rod, a push rod, a sliding rod, and a cooperating rod;

[0020] Four positioning rods are fixedly installed on two support rods respectively. Four positioning frames are slidably connected to the bottom of the platform. Two connecting plates are fixedly connected to the four positioning frames respectively. Two driving plates are fixedly connected to the two connecting plates respectively. The control plate is fixedly connected to the driving plate located on the right side. The second electric push rod is fixedly installed at the bottom of the platform. The output shaft of the second electric push rod is fixedly connected to the control plate. The push rod is rotatably connected to the sliding rod and the control plate respectively. The sliding rod is slidably connected to the bottom of the platform. The sliding rod is vertically connected to the bottom of the platform. The sliding rod cooperates with the mating rod. The mating rod is fixedly connected to the driving rod located on the left side.

[0021] Furthermore, the support mechanism drives the control board and the drive plate via the second electric push rod. When the output shaft box of the second electric push rod extends to the left, it directly pushes the control board and the drive plate located on the right to move to the left. The drive plate located on the right will drive the connecting plate and the two positioning frames located on the right to move to the left. The positioning frames disengage from the positioning rods, unlocking the right side of the platform. Then, the control board pushes the push rod, which pushes the sliding rod downward. The sliding rod squeezes the mating rod, the drive rod located on the left, and the connecting rod through the round block, which can drive the two positioning frames located on the left to disengage from the two positioning rods, unlocking the left side of the platform. This allows the platform to rise and fall freely. When the output shaft of the second electric push rod retracts, it will also link multiple positioning frames and their insertion rods to insert into the insertion slots of the positioning rods. This can provide additional mechanical locking and support after the platform is raised and lowered to the target height, sharing the load of the hoisting ropes and greatly enhancing the platform's load-bearing capacity and wind load resistance during static operation.

[0022] Preferably, the safety mechanism includes: a safety bar, straps, safety vest, insertion frame, insertion sleeve, two fitting blocks, two blocking blocks, an unlocking frame, and a control block;

[0023] The safety bar is fixedly connected to the guardrail, the straps are fixedly connected to the guardrail, the straps are fixedly connected to the insertion frame, the outer side of the insertion frame slides in contact with the inner wall of the insertion sleeve, both fitting blocks are fixedly connected to the insertion frame, the tops of both fitting blocks slide in contact with the inner wall of the insertion sleeve, the insertion sleeve is fixedly connected to the safety vest, both blocking blocks are rotatably connected to the top of the insertion frame, the bottom of the blocking blocks slides in contact with the top of the insertion sleeve, the unlocking frame is vertically connected to the top of the insertion frame, and the control block is fixedly installed on the top of the unlocking frame.

[0024] Furthermore, the safety agency provides a convenient and reliable second layer of personal protection for workers by quickly inserting the insertion sleeve on the safety suit into the insertion frame connected to the strap on the platform railing and using the blocking blocks for automatic locking. Even if the platform shakes unexpectedly, the personnel can be protected by the safe connection to the platform, reducing the risk of falling from height. After pushing the control block on the insertion frame, the control block can drive the unlocking frame to move downwards. The unlocking frame can then use two round rods to push the two blocking blocks to disengage from the insertion sleeve, unlocking the insertion frame and allowing the insertion frame and safety suit to be separated.

[0025] Preferably, the top and bottom of the two support rods are provided with rectangular through holes, and the number of rectangular through holes is four. The inner side of the rectangular through holes is an arc-shaped structure, and the two suspension ropes slide in contact with the inner walls of the four rectangular through holes respectively.

[0026] Furthermore, the arc-shaped rectangular through holes at the top and bottom of the support rod provide a smooth guiding and limiting channel for the hoisting rope, reducing friction and wear during the hoisting rope's raising and lowering process, while preventing the hoisting rope from coming off or interfering with the surrounding structure, thus ensuring smooth and safe lifting and lowering operations.

[0027] Preferably, each of the four positioning frames is fixedly equipped with an insertion rod, and each of the four positioning rods has multiple insertion slots arranged at equal intervals, with the outer side of the insertion rod sliding in contact with the inner wall of the insertion slot.

[0028] Furthermore, the insertion rods on the positioning frame cooperate with the equidistantly arranged insertion slots on the positioning rods to provide multiple selectable locking positions for the support mechanism, enabling the platform to obtain rigid support and locking at multiple preset heights, adapting to the height fixing requirements of different work tasks, and enhancing the applicability of the work platform.

[0029] Preferably, a circular block is fixedly installed on the rear side of the left end of the sliding rod, and the outer side of the circular block is slidably connected to the inner wall of the mating rod.

[0030] Furthermore, the circular block at the left end of the sliding rod is slidably connected to the inner wall of the mating rod, converting the linear motion of the sliding rod into a drive for the left driving plate, realizing the linkage between the left and right sides of the support mechanism, ensuring that the support points on both sides of the platform can move synchronously, and maintaining the balance and symmetry of the support force.

[0031] Preferably, the bottom of the unlocking frame is fixedly equipped with two symmetrically arranged round rods, and the outer sides of the two round rods slide in contact with the top inner walls of the two blocking blocks respectively.

[0032] Furthermore, the two round rods at the bottom of the unlocking frame slide in contact with the top inner walls of the two blocking blocks respectively. When the unlocking frame is pulled down, the round rods can simultaneously squeeze the two blocking blocks, causing them to disengage from the locking of the insertion sleeve, thereby realizing quick one-handed unlocking of the safety connection device, which is convenient to operate.

[0033] Preferably, a torsion spring is fixedly installed at the bottom of each of the two blocking blocks, and the bottom end of each torsion spring is fixedly connected to the top of the insertion bracket.

[0034] Furthermore, the torsion springs installed at the bottom of the two blocking blocks provide them with a continuous elastic locking force, ensuring that after the insertion bracket and the insertion sleeve are connected, the blocking blocks can automatically pop up and lock the insertion sleeve, achieving reliable locking. This automatic locking function improves the convenience and reliability of the safety mechanism.

[0035] In summary, the technical effects and advantages of this invention are as follows:

[0036] 1. The stabilizing mechanism drives the connecting rod and the bonding frame through the first electric push rod, so that the bonding frame can be tightly pressed onto the steel cable, increasing the contact area and friction between the platform and the load-bearing steel cable, effectively suppressing the swaying and sliding of the platform under wind or operating load, and significantly improving the overall stability and safety during high-altitude operations.

[0037] 2. The lifting mechanism controls the winding roller to wind up and unwind the hoisting rope through the winding motor, thereby smoothly raising or lowering the platform with guardrails. This enables precise electric adjustment of the working height of the staff, allowing the platform to adapt to maintenance work needs at different heights, replacing the limitations of traditional methods where personnel have to climb or where the height is difficult to adjust.

[0038] 3. The support mechanism drives the control board and the drive plate via the second electric push rod. When the output shaft box of the second electric push rod extends to the left, it directly pushes the control board and the drive plate located on the right to move to the left. The drive plate located on the right will drive the connecting plate and two positioning frames located on the right to move to the left. The positioning frames disengage from the positioning rods, unlocking the right side of the platform. Then, the control board pushes the push rod, which pushes the sliding rod downward. The sliding rod squeezes the mating rod, the drive rod located on the left, and the connecting rod through the round block, which can drive the two positioning frames located on the left to disengage from the two positioning rods, unlocking the left side of the platform. This allows the platform to rise and fall freely. When the output shaft of the second electric push rod retracts, it will also link multiple positioning frames and their insertion rods to insert into the insertion slots of the positioning rods. This can provide additional mechanical locking and support after the platform is raised and lowered to the target height, share the load of the hoisting rope, and greatly enhance the load-bearing capacity and wind load resistance of the platform during static operation.

[0039] 4. The safety mechanism provides workers with a convenient and reliable second line of defense by quickly inserting the insertion sleeve on the safety suit into the insertion frame connected to the strap on the platform railing and automatically locking it with the blocking blocks. Even if the platform shakes unexpectedly, the personnel can be protected by the safe connection to the platform, reducing the risk of falling from height. After pushing the control block on the insertion frame, the control block can drive the unlocking frame to move downward. The unlocking frame can then use two round rods to push the two blocking blocks to disengage from the insertion sleeve, unlocking the insertion frame and allowing the insertion frame and safety suit to be separated.

[0040] This invention integrates a moving mechanism, a stabilizing mechanism, a lifting mechanism, a supporting mechanism, and a safety mechanism to construct a multifunctional composite system. The moving mechanism enables the platform to move along the power transmission line, the stabilizing mechanism ensures overall stability during movement and operation, the lifting and supporting mechanisms enable flexible adjustment and reliable locking of the working height, and the safety mechanism provides direct protection for personnel. This invention comprehensively solves the problems of insufficient stability, difficulty in height adjustment, and poor safety of traditional suspended trolleys. Attached Figure Description

[0052] 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.

[0053] Example

[0054] refer to Figure 1-10 This embodiment proposes an aerial work platform for ultra-high voltage transmission line engineering, comprising:

[0055] The base 1 has a moving mechanism installed on its top. The moving mechanism includes four brackets 2, four guide wheels 3, four auxiliary wheels 4, two steel cables 5, and four drive motors 39. The brackets 2 are fixedly installed on the top of the base 1. The guide wheels 3 and auxiliary wheels 4 are rotatably connected to the brackets 2.

[0056] The stabilizing mechanism is used to stabilize the position of base 1;

[0057] Lifting mechanism, used to adjust the height of staff;

[0058] Support structure, used to support the height of the staff;

[0059] Safety agencies are responsible for ensuring the safety of their staff.

[0060] There are two sets of stabilizing mechanisms. The stabilizing mechanism works in conjunction with the support frame 2 and the steel cable 5. The lifting mechanism and the supporting mechanism work in conjunction with the base 1. The safety mechanism works in conjunction with the lifting mechanism.

[0061] By integrating the above structure with a moving mechanism, a stabilizing mechanism, a lifting mechanism, a supporting mechanism, and a safety mechanism, a multifunctional composite system is constructed. The moving mechanism enables the platform 6 to move along the power transmission line, the stabilizing mechanism ensures overall stability during movement and operation, the lifting and supporting mechanisms enable flexible adjustment and reliable locking of the working height, and the safety mechanism provides direct protection for personnel. This comprehensively solves the problems of insufficient stability, difficulty in height adjustment, and poor safety of traditional suspended trolleys.

[0062] As a preferred embodiment of this invention, the stabilizing mechanism includes: two bonding frames 10, a connecting rod 11, and two first electric push rods 12;

[0063] The bonding frame 10 is fixedly installed on the top of the connecting rod 11. The bonding frame 10 slides in contact with the steel cable 5. The first electric push rod 12 is fixedly connected to the bracket 2. The output shaft of the first electric push rod 12 is fixedly connected to the connecting rod 11. The stabilizing mechanism drives the connecting rod 11 and the bonding frame 10 through the first electric push rod 12, so that the bonding frame 10 can be tightly pressed onto the steel cable 5, increasing the contact area and friction between the platform 6 and the bearing steel cable 5, effectively suppressing the swaying and sliding of the platform 6 under wind or operating load, and significantly improving the overall stability and safety during high-altitude operations.

[0064] In a preferred embodiment of this invention, the lifting mechanism includes: a platform 6, a guardrail 7, a frame door 8, two support rods 13, two suspension ropes 14, two winding rollers 15, two winding frames 16, and two winding motors 17.

[0065] Platform 6 is slidably connected to the inside of four supports 2. Guardrail 7 is fixedly installed on the top of platform 6. Frame door 8 is installed on platform 6 and guardrail 7. Two support rods 13 are fixedly installed on the top of platform 6. Two hoisting ropes 14 are fixedly installed on the top of guardrail 7. Hoisting ropes 14 pass through support rods 13 and are wound around take-up roller 15. Take-up roller 15 is rotatably connected to take-up frame 16. Take-up frame 16 is fixedly installed on the top of base 1. Take-up motor 17 is fixedly installed on take-up frame 16. The output shaft of take-up motor 17 is fixedly connected to take-up roller 15. The lifting mechanism controls take-up roller 15 to take up and release hoisting rope 14 through take-up motor 17, thereby smoothly raising or lowering platform 6 with guardrail 7. This achieves electric and precise adjustment of the operator's working height, enabling platform 6 to adapt to maintenance work needs at different heights, replacing the limitations of traditional methods that require personnel to climb or have difficulty adjusting the height.

[0066] As a preferred embodiment of this example, the support mechanism includes: four positioning rods 18, four positioning frames 19, two connecting plates 21, two driving plates 22, a control plate 23, a second electric push rod 24, a push rod 25, a sliding rod 26, and a cooperating rod 27.

[0067] Four positioning rods 18 are fixedly installed on two support rods 13 respectively. Four positioning frames 19 are slidably connected to the bottom of the platform 6. Two connecting plates 21 are fixedly connected to the four positioning frames 19 respectively. Two driving plates 22 are fixedly connected to the two connecting plates 21 respectively. The control plate 23 is fixedly connected to the driving plate 22 located on the right side. The second electric push rod 24 is fixedly installed on the bottom of the platform 6. The output shaft of the second electric push rod 24 is fixedly connected to the control plate 23. The push rod 25 is rotatably connected to the sliding rod 26 and the control plate 23 respectively. The sliding rod 26 is slidably connected to the bottom of the platform 6. The sliding rod 26 is vertically connected to the bottom of the platform 6. The sliding rod 26 cooperates with the mating rod 27. The mating rod 27 is fixedly connected to the driving rod located on the left side. The support mechanism drives the control plate 23 and the driving plate 22 through the second electric push rod 24. When the output shaft box of the second electric push rod 24 extends to the left, it will directly push the control plate 23 and the driving plate 22 located on the right side. The drive plate 22 moves to the left, and the drive plate 22 on the right side will drive the connecting plate 21 and the two positioning frames 19 on the right side to move to the left. The positioning frames 19 disengage from the positioning rods 18, unlocking the right side of the platform 6. Then the control plate 23 will push the push rod 25, which will push the sliding rod 26 downward. The sliding rod 26 will squeeze the mating rod 27, the drive rod and the connecting rod 11 on the left side through the round block 28, which will drive the two positioning frames 19 on the left side to disengage from the two positioning rods 18, unlocking the left side of the platform 6. This allows the platform 6 to rise and fall freely. When the output shaft of the second electric push rod 24 retracts, it will also link multiple positioning frames 19 and their insertion rods 20 to insert into the insertion slots of the positioning rods 18. This will provide additional mechanical locking and support after the platform 6 is raised and lowered to the target height, sharing the load of the hoisting rope 14 and greatly enhancing the load-bearing capacity and wind resistance stability of the platform 6 during static operation.

[0068] As a preferred embodiment of this example, the safety mechanism includes: a safety bar 9, a strap 29, a safety vest 30, an insertion frame 31, an insertion sleeve 32, two fitting blocks 33, two blocking blocks 34, an unlocking frame 35, and a control block 38.

[0069] Safety bar 9 is fixedly connected to guardrail 7, strap 29 is fixedly connected to guardrail 7, strap 29 is fixedly connected to insertion frame 31, the outer side of insertion frame 31 slides in contact with the inner wall of insertion sleeve 32, two fitting blocks 33 are fixedly connected to insertion frame 31, the tops of the two fitting blocks 33 slide in contact with the inner wall of insertion sleeve 32, insertion sleeve 32 is fixedly connected to safety vest 30, two blocking blocks 34 are rotatably connected to the top of insertion frame 31, the bottom of blocking block 34 slides in contact with the top of insertion sleeve 32, unlocking frame 35 is vertically connected to the top of insertion frame 31, control block 38 is fixedly installed on the top of unlocking frame 35, safety mechanism By quickly inserting the insertion sleeve 32 on the safety vest 30 into the insertion frame 31 connected to the strap 29 on the guardrail 7 of the platform 6, and automatically locking it with the blocking block 34, a convenient and reliable second personal fixation connection is provided for the workers. Even if the platform 6 shakes unexpectedly, the personnel can be protected by the safe connection with the platform 6, reducing the risk of falling from a height. After pushing the control block 38 on the insertion frame 31, the control block 38 can drive the unlocking frame 35 to move downward. The unlocking frame 35 can then use the two round rods 37 to squeeze the two blocking blocks 34 to disengage from the insertion sleeve 32, unlocking the insertion frame 31 and allowing the insertion frame 31 and the safety vest 30 to be separated.

[0070] In this embodiment, rectangular through holes are provided at the top and bottom of both support rods 13, and there are four rectangular through holes. The inner side of the rectangular through holes is an arc-shaped structure. The two suspension ropes 14 slide in contact with the inner walls of the four rectangular through holes respectively. The arc-shaped rectangular through holes at the top and bottom of the support rods 13 provide a smooth guide and limiting channel for the suspension ropes 14, reducing the friction and wear of the suspension ropes 14 during the lifting and lowering process, and preventing the suspension ropes 14 from coming off or interfering with the surrounding structure, thus ensuring the smoothness and safety of the lifting and lowering operation.

[0071] In this embodiment, each of the four positioning frames 19 is fixedly equipped with an insertion rod 20, and each of the four positioning rods 18 has multiple insertion slots arranged at equal intervals. The outer side of the insertion rod 20 slides in contact with the inner wall of the insertion slot. The insertion rod 20 on the positioning frame 19 cooperates with the insertion slots arranged at equal intervals on the positioning rod 18, providing multiple selectable locking positions for the support mechanism. This allows the platform 6 to obtain rigid support and locking at multiple preset heights, adapting to the height fixing requirements of different work tasks and enhancing the applicability of the work platform 6.

[0072] In this embodiment, a circular block 28 is fixedly installed on the rear side of the left end of the sliding rod 26. The outer side of the circular block 28 is slidably connected to the inner wall of the mating rod 27. The circular block 28 at the left end of the sliding rod 26 is slidably connected to the inner wall of the mating rod 27, which converts the linear motion of the sliding rod 26 into driving the left driving plate 22, realizing the linkage between the left and right sides of the support mechanism, ensuring that the support points on both sides of the platform 6 can move synchronously, and maintaining the balance and symmetry of the support force.

[0073] In this embodiment, two symmetrically arranged round rods 37 are fixedly installed at the bottom of the unlocking frame 35. The outer sides of the two round rods 37 slide in contact with the top inner walls of the two blocking blocks 34 respectively. When the unlocking frame 35 is pulled down, the round rods 37 can simultaneously squeeze the two blocking blocks 34, causing them to disengage from the locking of the insertion sleeve 32, thereby realizing the quick one-handed unlocking of the safety connection device, which is convenient to operate.

[0074] In this embodiment, torsion springs 36 are fixedly installed at the bottom of both blocking blocks 34. The bottom ends of both torsion springs 36 are fixedly connected to the top of the insertion frame 31. The torsion springs 36 installed at the bottom of the two blocking blocks 34 provide them with a continuous elastic locking force, ensuring that after the insertion frame 31 and the insertion sleeve 32 are docked, the blocking blocks 34 can automatically pop up and lock the insertion sleeve 32, thus achieving reliable locking. This automatic locking function improves the convenience and reliability of the safety mechanism.

[0075] Working Principle: By integrating a moving mechanism, a stabilizing mechanism, a lifting mechanism, a supporting mechanism, and a safety mechanism, the stabilizing mechanism drives the connecting rod 11 and the bonding frame 10 through the first electric push rod 12, allowing the bonding frame 10 to be tightly pressed onto the steel cable 5. This increases the contact area and friction between the platform 6 and the load-bearing steel cable 5, effectively suppressing the swaying and sliding of the platform 6 under wind or operational loads, significantly improving the overall stability and safety during high-altitude operations. The supporting mechanism drives the control board 23 and the drive plate 22 through the second electric push rod 24. When the output shaft box of the second electric push rod 24 extends to the left, it directly pushes the control board 23 and the drive plate 22 located on the right to move to the left. The drive plate 22 located on the right will then drive the drive plate 22 located on the right to move to the left. The connecting plate 21 and the two positioning frames 19 move to the left, disengaging the positioning frames 19 from the positioning rods 18, unlocking the right side of the platform 6. Then, the control plate 23 pushes the push rod 25, which in turn pushes the sliding rod 26 downward. The sliding rod 26, through the circular block 28, actuates the mating rod 27, the driving rod on the left side, and the connecting rod 11, thereby disengaging the two positioning frames 19 from the two positioning rods 18 and unlocking the left side of the platform 6. This allows the platform 6 to be raised and lowered freely. The lifting mechanism controls the winding roller 15 to wind and unwind the hoisting rope 14 via the winding motor 17, thus smoothly raising or lowering the platform 6 with the guardrail 7. This achieves precise electric adjustment of the worker's working height, enabling the platform 6 to adapt to inspections at different heights. The system addresses maintenance needs, overcoming the limitations of traditional methods that require personnel to climb or have difficulty adjusting the height. After adjustment, the second electric push rod 24 is activated. When the output shaft of the second electric push rod 24 retracts, it also triggers multiple positioning frames 19 and their insertion rods 20 to insert into the insertion slots of the positioning rod 18. This provides additional mechanical locking and support after the platform 6 is raised or lowered to the target height, sharing the load of the hoisting rope 14 and greatly enhancing the load-bearing capacity and wind resistance stability of the platform 6 during static operations. The safety mechanism quickly connects the insertion sleeve 32 on the safety vest 30 to the insertion frame 31 connected to the strap 29 on the platform 6 guardrail 7, and automatically locks it using the blocking block 34, providing workers with a convenient and reliable second layer of personal protection. Even if the platform 6 accidentally shakes... The system allows personnel to be protected through a secure connection with platform 6, reducing the risk of falls from heights. After pushing control block 38 on insertion frame 31, control block 38 can drive unlocking frame 35 to move downwards. Unlocking frame 35 can then use two round rods 37 to push two blocking blocks 34 to disengage from insertion sleeve 32, unlocking insertion frame 31 and allowing insertion frame 31 and safety clothing 30 to be separated. This creates a multi-functional composite system. The moving mechanism allows platform 6 to move along the power transmission line, the stabilizing mechanism ensures overall stability during movement and operation, the lifting and supporting mechanism enables flexible adjustment and reliable locking of working height, and the safety mechanism provides direct protection for personnel. This system comprehensively solves the problems of insufficient stability, difficulty in height adjustment, and poor safety of traditional suspended pulleys.
