Description

Technical Field

[0001] This invention belongs to the field of power equipment technology, specifically a power operation and maintenance insulated operating platform frame. Background Technology

[0002] Power operation and maintenance refers to the maintenance of power lines, power operation and emergency repairs by professional teams. Since power systems are generally installed at high altitudes, insulated operating platforms are usually required during the implementation of power operation and maintenance.

[0003] For example, utility model publication CN214204648U discloses a power maintenance insulated operating platform frame, including a ladder frame. Two strip blocks are fixedly connected to the right side wall of the ladder frame. Limiting grooves are formed on opposite sides of each strip block. Adjustable sliding plates are slidably connected to the inner walls of the two limiting grooves. An operating platform and a first threaded adjusting rod are rotatably connected to the right side wall of each adjusting sliding plate via bearing seats. This power maintenance insulated operating platform frame, by setting up the ladder frame, strip blocks, limiting grooves, adjusting sliding plates, and operating platform, allows power maintenance personnel to stand on the operating platform to work, expanding the standing area for workers. Safety is protected by guardrails. By setting up auxiliary poles, the platform frame can be hung on the surface of building steps to prevent the ladder frame from tipping over, thus improving safety.

[0004] For example, CN115173293A discloses a power maintenance insulation operation platform frame, relating to the field of power maintenance technology. This invention includes a ladder, supporting vertical plates, and a support assembly. The support assembly is located at the front of the ladder, and a frustum plate is connected to the upper rear side of the ladder. Below the frustum plate, a ladder and two supporting vertical plates are arranged in a circular array. An L-shaped plate is connected to the lower front side of the ladder, and rollers are provided on the lower left and right sides of the ladder. A caster wheel is provided on the lower side of one side of each supporting vertical plate. This invention, by setting up the support assembly, prevents users from falling through the gap between the two horizontal plates and increases the user's range of movement on the support assembly. The addition of the ladder, supporting vertical plates, and frustum plate increases the applicable space for this power maintenance insulation operation platform frame, thereby improving its practicality. Furthermore, the L-shaped plate, caster wheel, and rollers enable the power maintenance insulation operation platform frame to transport users.

[0005] Although the above-mentioned device can perform maintenance operations on high-altitude electrical equipment by raising the platform, there are still cases in actual use where the platform plate may suddenly fall, which could lead to danger for people on the operating platform. Therefore, an insulated operating platform frame for power operation and maintenance is proposed to solve the problems mentioned in the background art. Summary of the Invention

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] This invention utilizes the cooperation between a platform plate structure, gears, cylindrical locking blocks, and elastic springs to prevent the platform plate from suddenly falling and improve safety. When the sliding block accidentally slips, its rapid descent causes the gears to rotate rapidly. This rotation generates centrifugal force, causing the cylindrical locking blocks to move outwards. Simultaneously, the elastic spring is compressed, disengaging the outer end of the cylindrical locking blocks from the gears. The cylindrical locking blocks then engage with the second toothed plate, meshing with the elastic spring. This allows the gears to contact the first toothed plate while simultaneously engaging with the second toothed plate, thus restricting the gears from rotating and preventing the sliding block and operating platform from slipping. This also prevents dangerous situations caused by the rapid fall of the operating platform.

[0022] This invention utilizes the cooperation between structures such as threaded posts, bottom pins, limiting posts, and piston plates to prevent the bottom of the frame from sliding. By engaging the top of the frame with the crossbar, and with the bottom of the frame in contact with the ground, rotating the bottom plate brings it into contact with the ground. Then, the operator rotates the threaded post, extending the length of the engagement between the threaded post and the L-shaped groove. The operator then presses the threaded post downwards, causing the L-shaped groove to sink into the ground. Simultaneously, the limiting post causes the piston plate to move downwards. At this point, the gas inside the bottom plate, located below the piston plate, enters the inner cavity at the bottom of the frame through the L-shaped groove. The device then secures the bottom of the frame, preventing it from sliding.

[0023] This invention utilizes the cooperation between the bent pipe, the first T-block, the inner rod, and the second T-block to achieve a strong fixation of the top of the frame. When gas enters the inner cavity at the bottom of the frame through the bottom plate, it pushes the first and second T-blocks on both sides of the top of the bent pipe to move towards each other. After the first and second T-blocks come into contact, the gas inside the bent pipe further pushes the inner rod into the inner cavity of the second T-block. When the magnet inside the inner rod is above the iron block, the magnetic attraction of the magnet causes the top of the outer surface of the iron block to engage with the inner cavity of the inner rod. Simultaneously, the gas inside the bent pipe, through the ventilation pipe, compresses the bottom of the iron block, making the iron block and the inner rod more securely engaged. This prevents the first and second T-blocks from falling off, thus ensuring a more stable fixation of the top of the frame. Attached Figure Description

[0034] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] like Figures 1 to 9As shown, this invention provides a power operation and maintenance insulation operating platform frame, including a frame body 1. The frame body 1 is characterized by: limiting rods 2 fixedly connected to the front and rear ends of its inner cavity; a platform plate structure 3 movably connected to the bottom of the outer surface of the limiting rods 2; a connecting protective cover 4 fixedly connected to one side of the platform plate structure 3; a power motor 5 fixedly connected to the inner cavity of the connecting protective cover 4; a first bevel gear 6 fixedly connected to the output shaft end of the power motor 5; a connecting shaft 7 movably connected to the inner cavities of the top sides of the connecting protective cover 4; gears 10 and a second bevel gear 8 fixedly connected to the front, rear, and middle portions of the outer surface of the connecting shaft 7, respectively; limiting sliders 9 movably connected to the front and rear ends of the inner cavity of the frame body 1; cylindrical locking blocks 11 movably connected at equal angles to the front and rear ends of the inner cavity of the second bevel gear 8; a spring spring 12 sleeved on the outer surface of the cylindrical locking blocks 11; and first toothed plates 13 and second toothed plates 14 fixedly connected to the sides of the inner cavities of the front and rear ends of the frame body 1. In the event of an accidental slippage of the sliding block 301, the sliding block 301... The rapid descent of 01 will cause gear 10 to rotate rapidly. This rotation will generate centrifugal force, causing the cylindrical locking block 11 to move outwards. Simultaneously, the spring spring 12 will be compressed, causing the outer end of the cylindrical locking block 11 to disengage from the gear 10. The cylindrical locking block 11 then engages with the second toothed plate 14, thus allowing gear 10 to contact the first toothed plate 13 while simultaneously engaging with the cylindrical locking block 11 and the second toothed plate 14. This restricts the rotation of gear 10 from both sides, preventing the sliding block 301 and the operating platform 302 from slipping. This also prevents people on the operating platform 302 from falling rapidly, thus improving safety during use.

[0037] like Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, the first bevel gear 6 and the second bevel gear 8 are meshed together. The outer surface of the connecting shaft 7 is movably connected to the inner cavity of the limiting slider 9. The gear 10 is meshed with the first toothed plate 13. The outer end and the inner end of the elastic spring 12 are fixedly connected to the gear 10 and the cylindrical locking block 11, respectively. The shortest distance between the gear 10 and the second toothed plate 14 is less than half the length of the cylindrical locking block 11. By running the power motor 5, the first bevel gear 6 will drive the second bevel gear 8 to rotate, which in turn will cause the limiting slider 9 to drive the gear 10 to rotate. At this time, through the cooperation between the gear 10 and the first toothed plate 13, and through the limiting action of the limiting slider 9 and the connecting protective cover 4, the platform plate structure 3 can rise and fall. At the same time, through the design of the cylindrical locking block 11, when the platform plate structure 3 has not yet fallen, the cylindrical locking block 11 and the gear 10 are prevented from contacting the second toothed plate 14, thus ensuring the normal operation of the device.

[0038] Example 2

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the inner cavity bearings at the front and rear ends of the frame 1 are connected to a base plate 15. A piston plate 16 is movably connected to the top of the inner cavity of the base plate 15. A limit post 17 is movably connected to the inner cavity of the piston plate 16. A bottom nail 18 is fixedly connected to the inner cavity of the piston plate 16 on the side away from the limit post 17. A threaded post 19 is threadedly connected to the inner cavity of the bottom nail 18. An L-shaped groove 20 is formed at the bottom of the base plate 15 on the side away from the bottom nail 18. By inserting the top of the frame 1 into the crossbar, and since the bottom of the frame 1 is in contact with the ground, rotating the base plate 15 will cause the base plate 15 to... When the threaded post 19 comes into contact with the ground, the operator rotates the threaded post 19 to extend the length of the fit between the threaded post 19 and the L-shaped groove 20. Then the operator presses the threaded post 19 down to drive the L-shaped groove 20 into the ground. At the same time, due to the limiting effect of the limiting post 17, the piston plate 16 will also move downward. At this time, the gas inside the bottom plate 15 located below the piston plate 16 will enter the inner cavity at the bottom of the frame 1 through the L-shaped groove 20. At this time, the device completes the fixation of the bottom of the frame 1, thereby preventing the bottom of the frame 1 from sliding.

[0040] It is worth noting that when electrical equipment is placed at a high place, protective structures and fixing devices are often installed on the electrical equipment. It is also reasonable to install a horizontal bar on the protective device or fixing device. In this case, the function of the horizontal bar is to facilitate the top of the frame 1 to rest on the horizontal bar, so that the horizontal bar can provide good support for the top of the frame 1.

[0041] like Figure 7 , Figure 8 , Figure 9 As shown, the front and rear ends of the inner cavity of the frame 1 are provided with bent pipes 21. The inner cavities on both sides of the top of the frame 1 are respectively movably connected to a first T-shaped block 22 and a second T-shaped block 24. The inner cavity of the first T-shaped block 22 is movably connected to an inner rod 23, and the inner cavity of the second T-shaped block 24 is movably connected to an iron block 25. The interior of the second T-shaped block 24 is provided with a ventilation pipe 26, and a magnet 27 is fixedly connected to the top of the inner cavity of the inner rod 23. When the gas inside the base plate 15 enters the inner cavity at the bottom of the frame 1, the gas will push the first T-shaped block 22 and the second T-shaped block 24 on both sides to move towards each other through the two sides of the top of the bent pipe 21. When the first T-shaped block 22 and the second T-shaped block 24 move towards each other... After block 24 comes into contact, the gas inside the bent pipe 21 will push the inner rod 23 to move into the inner cavity of the second T-shaped block 24. When the magnet 27 inside the inner rod 23 is above the iron block 25, the magnetic attraction of the magnet 27 will cause the top of the outer surface of the iron block 25 to be inserted into the inner cavity of the inner rod 23. At the same time, the gas inside the bent pipe 21 will squeeze the bottom of the iron block 25 through the ventilation pipe 26, so that the iron block 25 and the inner rod 23 are more firmly connected, thus preventing the first T-shaped block 22 and the second T-shaped block 24 from falling off, thereby making the top of the frame 1 more stable.

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the upper and lower ends of the limiting post 17 are fixedly connected to the top and bottom of the inner cavity of the base plate 15, respectively. One end of the bottom of the bottom nail 18 penetrates the bottom of the base plate 15 and extends to the bottom of the base plate 15. The bottom nail 18 is movably connected to the inner cavity at the bottom of the base plate 15. The outer surface of the threaded post 19 is movably connected to the inner cavity at the top of the base plate 15. The inner cavity of the base plate 15 is connected to the inner cavity at the top of the frame 1 through the L-shaped groove 20. Through the cooperation between the threaded post 19 and the bottom nail 18, the space occupied by the threaded post 19 and the bottom nail 18 is reduced when they are not in use.

[0043] like Figure 7 , Figure 8 , Figure 9As shown, the bent pipe 21 communicates with the inner cavity of the L-shaped groove 20 and the inner cavity of the base plate 15 through the inner cavity of the bottom of the frame 1. The outer surface of the inner rod 23 engages with the inner cavity of the second T-shaped block 24. The magnet 27 and the iron block 25 are of equal width. Through the design of the piston plate 16, when it is necessary to disconnect the connection between the top of the frame 1 and the crossbar, the operator moves the bottom nail 18 and the threaded post 19 upward, thereby reducing the pressure inside the bent pipe 21. At this time, through the action of the ventilation pipe 26, the iron block 25 will move downward, thereby releasing the iron block 25 from the engagement with the inner rod 23. Subsequently, the first T-shaped block 22 and the second T-shaped block 24 will reset due to the reduction of air pressure, thus facilitating subsequent operations by the operator.

[0044] Example 3

[0045] like Figure 1 , Figure 2 , Figure 3 As shown, the platform structure 3 includes a sliding block 301. The front and rear ends of the inner cavity of the sliding block 301 are movably connected to the outer surfaces of the front and rear limit rods 2, respectively. The top outer surface of the sliding block 301 is hinged to an operating table plate 302. The front and rear ends of the bottom of the operating table plate 302 away from the frame 1 are hinged to a first sleeve block 303. The inner cavity of the first sleeve block 303 is threadedly connected to a threaded rod 304. The front and rear ends of the bottom of the sliding block 301 away from the frame 1 are hinged to a second sleeve block 305. The second sleeve block 305 is bearing-connected to the threaded rod 304. By rotating the middle of the outer surface of the threaded rod 304, the length of the first sleeve block 303 and the threaded rod 304 will be extended or shortened due to the cooperation between them. This ensures that the operating table plate 302 remains horizontal when the frame 1 is tilted at different angles, thus facilitating its use.

[0046] Working principle and usage process of this invention:

[0047] First, the operator inserts the top of the frame 1 into the crossbar. Since the bottom of the frame 1 is in contact with the ground, the operator rotates the base plate 15 to make it contact the ground. Then, the operator rotates the threaded post 19 to extend the length of the fit between the threaded post 19 and the L-shaped groove 20. Then, the operator presses the threaded post 19 down to make the L-shaped groove 20 nail into the ground. At the same time, due to the limiting action of the limiting post 17, the piston plate 16 will also move downward. At this time, the gas inside the base plate 15 located below the piston plate 16 will enter the inner cavity at the bottom of the frame 1 through the L-shaped groove 20. At this time, the device completes the fixation of the bottom of the frame 1, thereby preventing the bottom of the frame 1 from having a good fixing effect.

[0048] When the gas inside the base plate 15 enters the inner cavity at the bottom of the frame 1, the gas will push the first T-shaped block 22 and the second T-shaped block 24 on both sides of the top of the bent pipe 21 to move towards each other. After the first T-shaped block 22 and the second T-shaped block 24 come into contact, the gas inside the bent pipe 21 will also push the inner rod 23 to move into the inner cavity of the second T-shaped block 24. When the magnet 27 inside the inner rod 23 is above the iron block 25, the magnetic attraction of the magnet 27 will cause the top of the outer surface of the iron block 25 to be stuck into the inner cavity of the inner rod 23. At the same time, the gas inside the bent pipe 21 will squeeze the bottom of the iron block 25 through the ventilation pipe 26, so that the iron block 25 and the inner rod 23 are more firmly stuck together, thereby preventing the first T-shaped block 22 and the second T-shaped block 24 from falling off, thus making the top of the frame 1 more stable.

[0049] When people are on the operating platform 302, if the sliding block 301 accidentally slips off, the rapid descent of the sliding block 301 will cause the gear 10 to rotate rapidly. The rotation of the gear 10 will generate centrifugal force, causing the cylindrical locking block 11 to move outwards. Simultaneously, the spring spring 12 will be compressed, causing the outer end of the cylindrical locking block 11 to disengage from the gear 10. The cylindrical locking block 11 then engages with the second toothed plate 14, thus meshing with the spring spring 12. This allows the gear 10 to contact the first toothed plate 13 while simultaneously engaging with the cylindrical locking block 11 and the second toothed plate 14, thereby restricting the rotation of the gear 10 from both sides and preventing the sliding block 301 and the operating platform 302 from slipping off.
