Description

Technical Field

[0001] This utility model relates to the field of construction platform technology, and in particular to a power grid construction high-altitude operation platform. Background Technology

[0002] With the continuous expansion of power grid construction and the sustained growth in the demand for power facility maintenance, power grid construction and maintenance operations are becoming increasingly frequent and face numerous challenges. In traditional power grid construction operations at height, simple ladders and fixed scaffolding are often used to assist personnel in climbing.

[0003] The power grid construction aerial work platform consists of a main platform, lifting device, support structure, power system, and safety devices. During work, the platform is first moved to the work position and the outriggers are adjusted. The platform height is then adjusted using a hydraulic or electric hoist lifting system. Workers operate on the platform, which is protected by guardrails. After work, the platform is lowered, the outriggers are retracted, and safety devices ensure safety throughout the process.

[0004] Existing technologies often lack flexible height adjustment for certain construction platforms, making it difficult to complete tasks at higher positions (such as insulator maintenance on tall utility poles or high-altitude wire connections). Workers may need to use ladders or other tools to climb, increasing the risk of accidents. Climbing is also physically demanding, affecting work efficiency and increasing the risk of falls. Compared to using a lifting platform, climbing requires more physical exertion and increases the risk of slipping or missteps. Furthermore, the lack of relatively safe protective facilities at heights, similar to lifting platforms, further increases the risk of falls and injuries. Therefore, this paper proposes a power grid construction aerial work platform to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a power grid construction high-altitude operation platform, which aims to improve the problem that the existing construction platform cannot flexibly adjust its height, resulting in the need to climb ladders to work at higher positions. This not only consumes physical strength and affects work efficiency, but also increases the risk of workers falling and getting injured due to the lack of corresponding safety protection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A power grid construction platform for working at height includes a floor. An electric push rod is fixedly connected to the top of the floor. A rack is fixedly connected to the drive end of the electric push rod. Multiple fixing rings are fixedly connected to the top of the floor. Two connecting rods are fixedly connected inside each fixing ring. Gears are fixedly connected to the outside of each connecting rod, and the outside of the two gears meshes with the outside of the two racks. Multiple connecting rods are fixedly connected to the opposite sides of each connecting rod. Connecting rods are fixedly connected to the front and rear sides of each connecting rod. Sliding columns are slidably connected inside each connecting rod. Multiple support rods are fixedly connected to the top of the floor. Secondary support rods are slidably connected inside each support rod. An adjustment component for protection is fixedly connected to the top of each secondary support rod.

[0008] As a further description of the above technical solution:

[0009] The adjustment assembly includes a support plate, the bottom of which is fixedly connected to the top of a plurality of secondary support rods. An electric push rod II is fixedly connected to the top of the support plate. A connecting column is fixedly connected to the drive end of the electric push rod II. Two sliding blocks are fixedly connected to opposite sides of the connecting column. A square slider is fixedly connected to the bottom of each of the two sliding blocks. Two other sliding blocks are fixedly connected to the top of the support plate. A rotating rod I is rotatably connected inside the two sliding blocks. A rotating rod II is fixedly connected inside the other two sliding blocks.

[0010] As a further description of the above technical solution:

[0011] The outer side of one of the gears is meshed with the outer side of another gear, and the bottom inner walls of the plurality of support rods are respectively fixedly connected to the outer side of the sliding column;

[0012] As a further description of the above technical solution:

[0013] The interior of each of the multiple support rods is provided with a groove, and the exterior of each of the multiple connecting rods is slidably connected to the interior of the multiple support rods;

[0014] As a further description of the above technical solution:

[0015] The top of the first rotating rod is rotatably connected to a guardrail, and the tops of the two second rotating rods are rotatably connected to the bottom of the guardrail.

[0016] As a further description of the above technical solution:

[0017] The bottom of the floor is fixedly connected to multiple sliding wheels, and the top of the support plate has two slots.

[0018] As a further description of the above technical solution:

[0019] The top of the support plate is fixedly connected to multiple lifting rods, and the two rotating rods 2 are externally rotatably connected to the inside of the rotating rod 1.

[0020] As a further description of the above technical solution:

[0021] The tops of the plurality of lifting bars are fixedly connected to the top of the guardrail, and the bottoms of the two sliding blocks are slidably connected to the top of the support plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the electric push rod is activated, the rack moves up and down linearly. The rack drives the gear meshing with it to rotate. The connecting rod drives the connecting rod to slide inside the support rod. Multiple sets of connecting rods evenly distribute the lifting force. The sliding column slides along the groove of the connecting rod and the support rod. The elevated work platform with lifting function can be precisely adjusted to a suitable height according to actual needs, so that construction personnel can easily reach different working positions. It can adapt well to work such as installing meter boxes, repairing insulators, or connecting lines.

[0024] 2. In this utility model, the electric push rod II extends and retracts, the connecting column drives the connected sliding block to move, the square slider slides along the top of the support plate and guides the sliding block connected to the connecting column to move, causing the rotating rod I to rotate, which drives the guardrail to rotate around the bottom connection point, thereby better preventing tools from slipping and reducing safety accidents caused by tools falling, such as injuring people on the ground or damaging equipment. By adjusting the height of the guardrail to achieve a suitable protective height, the risk of people falling from the platform can be effectively reduced. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 This utility model provides an embodiment of a power grid construction aerial work platform, including a floor 1. The floor 1 serves as the foundation of the entire platform, providing a stable mounting surface for other components such as an electric push rod 2. Its bottom sliding wheels facilitate the movement of the entire platform, allowing it to flexibly relocate within the construction site to meet the needs of different work points. An electric push rod 2 is fixedly connected to the top of the floor 1. The electric push rod 2 is one of the key power sources driving the platform's lifting and lowering. It drives a rack 3 to move up and down through telescopic movement, providing the initial power input for the subsequent rotation of the gear 4 and the entire lifting and lowering action, precisely controlling the platform's ascent and descent height. The drive end of the electric push rod 2 is fixedly connected to the rack 3, which moves linearly under the drive of the electric push rod 2. Multiple fixed rings are fixedly connected to the top of the floor 1. Each fixed ring has two connecting rods 5 fixedly connected inside. The connecting rods 5 connect the gears 4 and the connecting rod 6, transmitting force. Gears 4 are fixedly connected to the outside of each connecting rod 5, and are mounted on the connecting rods 5, meshing with the rack 3 for transmission. Two gears 4 mesh with each other, enabling synchronous and stable rotation when the rack 3 moves. The outer surfaces of the two gears 4 are meshed with the outer surfaces of the two racks 3. Multiple connecting rods 6 are fixedly connected to the opposite sides of the two connecting rods 5. The connecting rods 6 are connected to the connecting rods 5 and slide within the support rod 9 under the influence of the connecting rods 5. Through the coordinated movement of multiple sets of connecting rods 6, the lifting force can be evenly distributed and transmitted, keeping the platform level during lifting and providing a safe and stable working surface for construction personnel.

[0033] Connecting rods 7 are fixedly connected to the front and rear sides of connecting rod 6, providing a sliding track for sliding columns 8. During platform lifting, the sliding columns 8 slide along the interior of the connecting rods 7, acting as guides and stabilizers to prevent the connecting rod 6 from shifting or swaying during movement, further enhancing the stability and reliability of platform lifting. Sliding columns 8 are slidably connected inside the connecting rods 7. One end of the sliding column 8 is connected to the connecting rod 6, and the other end slides within the groove of the support rod 9 and is fixedly connected to the bottom inner wall of the secondary support rod 10. During platform lifting, it not only supports the connecting rod 6 but also slides within the support rod 9 as the connecting rod 6 moves, working in conjunction with the secondary support rod 10 to complete height adjustments and ensure the structural strength of the platform. Multiple support rods 9 are fixedly connected to the top of the floor 1. These support rods 9 guide and support the sliding of the connecting rod 6. Their internal grooves cooperate with the sliding column 8, restricting the movement direction of the sliding column 8 and ensuring that the connecting rod 6 can only move vertically along the support rods 9. This ensures the stability of the entire lifting assembly's trajectory and prevents the platform from swaying or deviating during lifting. A secondary support rod 10 is slidably connected inside the support rod 9. The secondary support rod 10 is slidably connected to the support rod 9, connected at the bottom to the sliding column 8, and fixedly connected at the top to the support plate 11. Adjusting the height of the support plate 11 changes the height of the platform's working surface and provides reliable vertical support for the platform. An adjustment component for protection is fixedly connected to the top of the secondary support rod 10.

[0034] Reference Figure 3 , Figure 4The adjustment assembly includes a support plate 11, which serves as the mounting base for the adjustment assembly. The support plate 11 bears the supporting force from the secondary support rods 10 and provides a stable mounting position for components such as the electric push rod 12. The bottom of the support plate 11 is fixedly connected to the top of multiple secondary support rods 10, and the top of the support plate 11 is fixedly connected to the electric push rod 12, which acts as the power drive in the adjustment assembly. Through its telescopic movement, it pushes the connecting column 13 to move, thereby driving the sliding block 14 and other components connected to the connecting column 13 to move, thus adjusting the angle of the guardrail 19. This meets the requirements for the position and angle of the guardrail 19 in different construction scenarios, improving operational safety. The drive end of the electric push rod 12 is fixedly connected to a connecting column 13. The connecting column 13 connects the electric push rod 12 to the sliding block 14, transmitting the linear driving force of the electric push rod 12 to the sliding block 14, enabling the sliding block 14 to move in a predetermined direction and trajectory. This, in turn, drives the related components of the guardrail 19 to adjust their angles, ensuring the continuity and precision of the guardrail 19's adjustment action. Two sliding blocks 14 are fixedly connected to opposite sides of the connecting column 13. The sliding blocks 14 are divided into two groups: one group is connected to the connecting column 13, and the other group is connected to either the rotating rod 17 or the rotating rod 18. A square slider 15 is fixedly connected to the bottom of each of the two sliding blocks 14. The square slider 15 is fixed to the bottom of the sliding block 14 and slides along the top of the support plate 11 when the sliding block 14 moves, serving to guide and stabilize the movement of the sliding block 14.

[0035] Two additional sliding blocks 14 are fixedly connected to the top of each support plate 11. The interior of each sliding block 14 is rotatably connected to a rotating rod 17. The rotating rod 17 drives the guardrail 19 to rotate around its bottom connection point, thereby changing the angle of the guardrail 19 and meeting the protection requirements under different working heights and positions. The interior of each of the other two sliding blocks 14 is fixedly connected to a rotating rod 2 18. The rotating rod 2 18 works in conjunction with the rotating rod 17 to support and change the position and angle of the guardrail 19, ensuring the stability of the guardrail 19 in different states.

[0036] Reference Figures 2 to 4 One gear 4 has its outer surface meshing with the outer surface of another gear 4. The bottom inner walls of multiple support rods 10 are fixedly connected to the outer surface of sliding columns 8. The sliding columns 8 support the connecting rod 6 and can slide within the support rods 9 as the connecting rod 6 moves, working in conjunction with the support rods 10 to complete height adjustment and ensure the structural strength of the platform. Grooves are formed inside the multiple support rods 9, and the outer surfaces of multiple connecting rods 6 are slidably connected to the interiors of the multiple support rods 9. The support rods 9 thus ensure the stability of the entire lifting assembly's movement trajectory and prevent the platform from swaying or deviating during lifting.

[0037] The top of rotating rod 17 is rotatably connected to guardrail 19, jointly supporting and changing the position and angle of guardrail 19 to ensure the stability of guardrail 19 in different states. The tops of two rotating rods 18 are rotatably connected to the bottom of guardrail 19. Multiple sliding wheels are fixedly connected to the bottom of the floor 1. The top of the support plate 11 has two slots 16, which are used to cooperate with the movement and positioning of other components, ensuring the accuracy and stability of the adjustment components and ensuring the normal functioning of the platform. Multiple lifting rods 20 are fixedly connected to the top of the support plate 11. The lifting rods 20 connect guardrail 19 and support plate 11. During the angle adjustment of guardrail 19, they extend or change angle as guardrail 19 rotates, playing a role in auxiliary support and stabilization of guardrail 19, so that guardrail 19 can maintain sufficient strength and stability in different positions and angles, reliably protecting construction personnel. Two rotating rods 18 are externally rotatably connected to the inside of rotating rod 17. The tops of multiple lifting rods 20 are fixedly connected to the top of guardrail 19, which surrounds the work platform to provide fall protection for construction workers. The rotating rods 17 and 18 are connected to an adjustment assembly, allowing the angle to be adjusted according to the platform's lifting height and operational needs. This effectively prevents workers from falling from the platform edge during construction, ensuring their safety. The bottoms of both sliding blocks 14 are slidably connected to the top of the support plate 11.

[0038] Working Principle: Using the sliding wheels at the bottom of the floor 1, the aerial work platform is pushed to the required construction position. Activating the electric push rod 2 moves the rack 3 vertically. The rack 3 drives the meshing gear 4 to rotate. Because the two gears 4 mesh, the connecting rod 5 rotates synchronously. The connecting rod 5 drives the connecting rod 6 to slide within the support rod 9. Multiple sets of connecting rods 6 evenly distribute the lifting force, ensuring the platform's horizontal movement. The sliding column 8 slides along the grooves of the connecting rod 7 and the support rod 9, working in conjunction with the secondary support rod 10 to adjust the height of the support plate 11, thus changing the platform's working surface height. The aerial work platform with lifting function can be precisely adjusted to the appropriate height according to actual needs, allowing construction personnel to easily reach different working positions. Whether installing meter boxes, inspecting insulators, or connecting lines, it adapts well. The lifting aerial work platform can avoid ground obstacles or adapt to terrain with different slopes by adjusting its height.

[0039] The secondary support rod 10 transmits force to the support plate 11. The electric push rod 12 extends and retracts, pushing the connecting column 13 to move. The connecting column 13 drives the connected sliding block 14 to move. The square slider 15 at its bottom slides along the top of the support plate 11, guiding the sliding block 14 connected to the connecting column 13 to move, causing the rotating rod 17 to rotate, driving the guardrail 19 to rotate around the bottom connection point. Another set of sliding blocks 14 and the rotating rod 18 work together to change the position and angle of the guardrail 19 to adapt to different construction scenarios. The adjustable guardrail 19 can flexibly change its shape or position, such as bending the guardrail 19 inward or increasing the height of the guardrail 19, thereby better preventing tools from slipping and reducing safety accidents caused by falling tools, such as injuring people on the ground or damaging equipment. By adjusting the height of the guardrail 19 to achieve a suitable protective height, the risk of people falling from the platform can be effectively reduced.
