Description

Technical Field

[0001] This invention relates to the technical field of high-voltage circuit maintenance, and more particularly to a live-line working platform for voltage levels of 220kV and below. Background Technology

[0002] In recent years, in order to effectively mitigate the risks of Level 1 and Level 2 events in power grid operation, eliminate the risks of routine substation switching operations, and reduce the heavy workload of operators, we are now gradually carrying out live-line disassembly and connection operations of busbar lead-out lines in 220kV and below substations.

[0003] In actual dismantling and erection work, due to space and environmental limitations within substations, current methods only include insulated bucket trucks with rigid ladders, insulated A-frame ladders, and insulated rigid ladders. Insulated A-frame ladders and rigid ladders are difficult to carry and install on-site due to their size and weight, especially requiring manual climbing of poles for installation and dismantling at the work site. This necessitates significant investment of manpower and resources, is time-consuming and labor-intensive, and increases construction risks. Secondly, since power grids are mostly located in mountainous areas, the use of insulated bucket trucks in such terrain is severely limited. For example, most bucket trucks cannot reach the site due to rugged and narrow terrain. Furthermore, the support legs used for reinforcement on the outside of the bucket truck often employ a disc-shaped base design. However, due to the uneven terrain, the large contact surface of the disc-shaped base makes it difficult to maintain a stable grip on irregular surfaces, posing a risk of slippage in mountainous terrain. Therefore, we propose a live-line working platform for 220kV and below voltage levels. Summary of the Invention

[0030] Example 1

[0031] Reference Figure 1This is the first embodiment of the present invention, which provides a live-line working platform with a voltage level of 220kV and below. The device includes a drive unit 100, including a drive component 101 located below, a support component 102 disposed above the drive component 101, and four sets of stabilizing components 103 disposed on both sides of the support component 102. The support component 102 and the drive component 101 are rotatably connected. The stabilizing components 103 are symmetrically disposed in pairs on both sides of the support component 102. The drive component 101 can drive the entire device to move, and the stabilizing components 103 can enhance the stability of the device when it is positioned and working at a certain location.

[0032] The support unit 200 includes a rotating component 201 located above the bearing component 102, a supporting component 202 disposed on the rotating component 201, and a work box 203 disposed at the outer end of the supporting component 202. The rotating component 201 is rotatably connected to the top of the bearing component 102 and can rotate circumferentially. The supporting component 202 can be extended according to usage requirements and is in a folded-back state in its normal state. The work box 203 provides space for workers to operate and move around. The entire unit is constructed of insulating material to effectively prevent leakage current conduction during operation, ensuring the personal safety of workers.

[0033] The reinforcement unit 300 includes a connecting member 301 located at the outer end of the stabilizing component 103, a connecting component 302 disposed below the connecting member 301, a spiral member 303 disposed between the connecting member 301 and the connecting component 302, three sets of first reinforcement components 304 disposed below the connecting member 301, a second reinforcement component 305 disposed below the first reinforcement components 304, and a return spring 306 sleeved on the spiral member 303. The connecting member 301 is connected to the outer end of the stabilizing component 103 and can move downward under the pressure of the stabilizing component 103. The spiral member 303 passes through the connecting member 301 and the connecting component 302. The two second reinforcement components 305 are connected between the connecting member 301 and the connecting component 302 and can overlap by folding inward.

[0034] During use, the entire device can be moved by the drive component 101, thus moving it to a designated working position such as a plain or mountain. Then, the stability of the device is reinforced by the expansion of the stabilizing component 103 to both sides. When the stabilizing unit 300 at the end of the stabilizing component 103 is compressed, it will contact the ground and expand outward on the ground, further increasing the stability of the device. Then, according to actual needs, the rotating component 201 is rotated to adjust the operating angle of the device. The working box 203 is then lifted to the designated working height by the extension support component 202 to further meet the working requirements.

[0035] Example 2

[0036] Reference Figure 1 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the driving component 101 enables free movement in mountainous terrain, and the large-scale support component 202 is set to meet more usage needs.

[0037] Compared to Embodiment 1, the driving component 101 further includes a driving assembly 101a located below the supporting component 102, and a motion assembly 101b sleeved on both sides of the driving assembly 101a. The motion assembly 101b is disposed outside the driving assembly 101a. The driving assembly 101a provides power for the overall movement of the driving component 101, and the driving assembly 101a is equipped with a remote control operating system. The driving component 101 can be remotely controlled by an externally connected remote control device. The motion assembly 101b is a tracked mobile structure. The tracked structure can adapt to various complex and rugged mountainous terrains, thereby better carrying out power maintenance work in mountainous areas.

[0038] The supporting component 102 includes a supporting component 102a located above the driving component 101a, and connecting ears 102b symmetrically arranged on both sides of the supporting component 102a. One end of the stabilizing component 103 is rotatably connected to the connecting ears 102b. The supporting component 102a is a transfer platform connecting the rotating component 201 and the driving component 101. The supporting component 102a and the driving component 101a are rotatably connected. The connecting ears 102b are used to connect and fix the stabilizing component 103. The inner end of the stabilizing component 103 is rotatably connected to the connecting ears 102b.

[0039] The stabilizing component 103 includes a support leg 103a connected to the connecting ear 102b, and a support cylinder 103b also connected to the connecting ear 102b and located above the support leg 103a. The support leg 103a is a rectangular structure with a bend, and the structure bends upward, forming a spider leg or crab leg structure. One end of the support cylinder 103b is rotatably connected to the connecting ear 102b, and the other end is rotatably located at the center of the upward protrusion of the support leg 103a. The support cylinder 103b can be extended and retracted.

[0040] During use, when the support cylinder 103b extends outward, its end is rotatably connected to the connecting ear 102b and is limited by the connecting ear 102b. Therefore, its top end will push the support leg 103a to move outward. The end of the support leg 103a is also limited by the connecting ear 102b. Therefore, the support leg 103a will rotate around the connection position between the bearing component 102a and the support leg 103a as the axis. With the push of the support cylinder 103b above, the support leg 103a will eventually rotate downward and the outermost end will press down on the ground. The four sets of support legs 103a press down simultaneously to form a stable structure that reinforces the stability of the device, ensuring that the device will not shift during use and further improving the safety of the device.

[0041] The rotating component 201 includes a rotating component 201a located above the bearing component 102a, and an adjusting cylinder 201b disposed on the upper side of the rotating component 201a and connected to the top of the supporting component 202. The rotating component 201a is rotatably connected to the bearing component 102a and can rotate in a circular or square manner, and has the function of adjusting the usage angle to meet more usage needs. The adjusting cylinder 201b is installed between the rotating component 201a and the supporting component 202, and can lift and move the supporting component 202 by means of support.

[0042] The support component 202 includes a support bucket arm 202a located on the side of the rotating component 201a, and an insulating arm 202b located at the other end of the support bucket arm 202a. The working bucket 203 is located at the outermost end of the insulating arm 202b. One end of the support bucket arm 202a is rotatably connected to the rotating component 201a, and the insulating arm 202b is rotatably connected to the other end of the support bucket arm 202a. The insulating arm 202b has a long insulating length of 3.4 meters, which exceeds the national standard requirements. It has a large load-bearing capacity and high insulation strength. The total length of the support bucket arm 202a and the insulating arm 202b, plus the vertical height of the drive component 101a and the load-bearing component 102a, is 14.8 meters when the support component 202 is in its maximum extended state, which can greatly meet more usage needs.

[0043] During use, the support arm 202a and the insulating arm 202b are composed of a folding structure, which can extend and expand the support length according to actual needs to adjust the vertical working position of the device, thereby meeting more usage requirements. The working bucket 203 is installed at the top of the support component 202, and its width is the maximum width of the upper conductor, ensuring the maximum safe distance between the upper device and the live parts during operation and ensuring the personal safety of the user. In conjunction with the rotating component 201a, which can rotate 360 ​​degrees continuously, the horizontal working position can be adjusted. Through the adjustment and coordination of the vertical and horizontal directions, the device can continuously complete multiple live operations in place without moving the vehicle position during use.

[0044] The remaining structure is the same as that in Example 1.

[0045] Example 3

[0046] Reference Figures 2-8 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that by increasing the number of contact points between the device and the ground through the reinforcement unit 300, the support area can be increased, the stability of the device on uneven mountainous terrain can be improved, and the risk of slippage can be reduced.

[0047] Compared to Embodiment 2, the connecting component 301 further includes a connecting frame 301a located at the outermost end of the support leg 103a, a push plate 301b disposed on one side of the connecting frame 301a, three sets of fixing ears 301c disposed on the bottom surface of the push plate 301b, and a conversion groove 301d disposed at the center of the push plate 301b. The connecting frame 301a has a triangular structure, which can better transmit the force of the device. The push plate 301b is fixedly connected to the side of the connecting frame 301a. The fixing ears 301c are disposed below the push plate 301b. The top end of the first reinforcing component 304 is rotatably connected to the fixing ears 301c. The spiral component 303 passes through the conversion groove 301d.

[0048] Furthermore, the conversion groove 301d has a structure that is large at both ends and narrow in the middle. The push disk 301b passes through it, and the spiral component 303 passes through it. The upper and lower sides of the conversion groove 301d are provided with misaligned surfaces 301d-1. The edges of the misaligned surfaces 301d-1 are smooth and have an arc-shaped cross-section. When they come into contact with the sides of the spiral component 303, the force of the spiral component 303 coming into contact with the inner side of the misaligned surface 301d-1 will be offset outward through the arc-shaped cross-section. The offset force will be directed above or below the conversion groove 301d.

[0049] The connecting component 302 includes a connecting disk 302a located outside the spiral component 303, a center of the connecting disk 302a, and three sets of connecting blocks 302c located outside the connecting disk 302a. A connecting hole 302b is fixedly located outside the connecting disk 302a. A movable groove 302c-1 is provided between every two sets of connecting blocks 302c. The end of the second reinforcing component 305 is connected to the movable groove 302c-1. Limiting grooves 302c-2 are provided on both sides of the connecting blocks 302c. The ends of the second reinforcing component 305 are rotatably connected to the limiting grooves 302c-2.

[0050] The spiral component 303 includes a spiral shaft 303a located between the connecting frame 301a and the connecting disk 302a, a cone head 303b disposed below the spiral shaft 303a, a connecting shaft 303c disposed at the top of the spiral shaft 303a, and a limiting piece 303d disposed at the top of the connecting shaft 303c. The cone head 303b is fixedly connected to the end of the spiral shaft 303a, the connecting shaft 303c is fixedly connected to the top of the spiral shaft 303a, and the limiting piece 303d is fixedly connected to the top of the connecting shaft 303c. The diameter of the connecting shaft 303c is larger than that of the fixing lug 301c and cannot pass through the conversion groove 301d. The diameter of the cone head 303b is the same as that of the connecting hole 302b and cannot pass through it. Therefore, the spiral component 303 as a whole is limited between the pushing disk 301b and the connecting assembly 302 by the cone head 303b and the connecting shaft 303c and will not detach from it.

[0051] During use, the spiral shaft 303a has an overall spiral structure with a relatively flat spiral arc. Its outer arc surface is a spirally ascending rectangular structure, referred to here as the spiral edge 303a-1. The spiral edge 303a-1 is in direct contact with the misaligned surface 301d-1 on the inner side of the conversion groove 301d. The forces between the two will interact when they come into contact. The connecting shaft 303c limits and isolates the upper half of the spiral component 303 above the push disk 301b, and the return spring 306 is sleeved on the upper part of the connecting shaft 303c, between the limiting plate 303d and the push disk 301b. The two ends of the return spring 306 are fixedly connected to the limiting plate 303d and the push disk 301b respectively. Through the tension of the return spring 306 itself, the two can be pulled closer together to achieve the purpose of reset.

[0052] The first reinforcement component 304 includes a reinforcement plate 304a located below the connecting frame 301a, a rotating shaft 304b disposed at the top of the reinforcement plate 304a, a rotating ear 304c disposed below the reinforcement plate 304a, and a first friction tooth 304d opened on one side below the reinforcement plate 304a. The inner side of the reinforcement plate 304a is provided with a groove that matches the second reinforcement component 305. The second reinforcement component 305 can be perfectly fitted and stored in the groove of the reinforcement plate 304a. When the two overlap, the ground of the two is at the same level. The rotating shaft 304b is rotatably connected in the fixed ear 301c, and the top of the second reinforcement component 305 is rotatably connected in the rotating ear 304c. The first friction tooth 304d is opened on the bottom surface of the reinforcement plate 304a to increase the friction with the ground.

[0053] Furthermore, the second reinforcing component 305 includes a base plate 305a located below the reinforcing plate 304a, a first fixed shaft 305b disposed at the lower end of the base plate 305a, a second fixed shaft 305c disposed at the top end of the base plate 305a, and a second friction tooth 305d disposed on the outer side of the base plate 305a. The first fixed shaft 305b is rotatably connected in the limiting groove 302c-2, and the second fixed shaft 305c is rotatably connected in the rotating ear 304c. The second friction tooth 305d is used to increase the friction with the ground. The first reinforcing component 304 and the second reinforcing component 305 can form a rectangular structure that can be folded together at a 90-degree angle.

[0054] During use, when the device needs to be fixed in a certain position, the support leg 103a is pressed down for positioning. The reinforcing unit 300 at the end of the support leg 103a will make contact with the ground. The cone head 303b will first make contact with the ground and will be pushed upward by the reverse force of the ground. The pushed cone head 303b will drive the spiral shaft 303a to move synchronously. The force of the spiral shaft 303a moving upward will be transmitted to the push plate 301b through the spiral edges 303a-1 on both sides. The push plate 301b will guide the upward force from the spiral component 303 into an outward offset force through the misaligned surface 301d-1 of the edge of the conversion groove 301d. In addition, the spiral shaft 303a has a threaded structure and follows the law of conservation of momentum. Finally, the upward force combined with the limiting action of the push plate 301b will cause the spiral component 303 to rotate upward while rotating. During the movement, the entire structure of the reinforcement unit 300, except for the spiral component 303, moves downwards. As the spiral component 303 rotates, a portion of the cone 303b, which is always in contact with the ground, will also penetrate into the soil. Meanwhile, the connecting component 302 above the cone 303b will come into contact with the ground and be subjected to upward pressure from the ground. Combined with the downward pressure of the connecting component 301, the first reinforcement component 304 and the second reinforcement component 305 located between the two will eventually unfold outwards. The unfolded first reinforcement component 304 and the second reinforcement component 305 form a trident structure. The trident structure has a certain degree of elasticity and deformation capability, which can adapt to different shapes and surfaces of the ground, increase stability on irregular or uneven surfaces, and thus better increase the stability of the device when used in mountainous environments.

[0055] The remaining structure is the same as that in Example 2.
