Description

Technical Field

[0001] The present invention relates to the technical field of power maintenance, and particularly to a foldable power automation maintenance rack with high safety. Background Technique

[0002] At present, in order to meet various demands, the power industry in our country is in a booming development stage. Therefore, power equipment construction and maintenance generally have the characteristics of tight construction periods and heavy tasks. In addition, there are many dangerous points at the power maintenance construction sites, and the working environment often changes. This includes power equipment in old communities. These equipment are usually the first-generation products due to early installation time and technical limitations, and have a long working life, with a relatively high probability of failure. These power equipment are usually installed in the green belts of the communities. When such power equipment fails and needs to be repaired and requires climbing heights, maintenance racks or aerial ladder trucks will be used. Although the maintenance rack is less affected by the maintenance space, when it is necessary to repair the power equipment adjacent to the current power equipment, the operators need to get off the ladder, move the ladder to a suitable position and then climb the ladder again, resulting in an increase in operation time. Although the aerial ladder truck can move within a certain range and shorten the operation time, it is greatly affected by the maintenance space and is easily restricted by the lines and building distances in old communities, limiting the movement range. During the transfer process, not only the aerial ladder needs to be moved but also the vehicle, which instead increases the operation time. There are also movable maintenance racks, but most of them are supported by wheels and are greatly affected by the terrain, making it impossible to guarantee the safety of the maintenance personnel on the rack during the movement process;

[0003] For example, a new type of power maintenance rack disclosed in the publication number CN206323049U uses wheels for support and is greatly affected by the terrain. When operating in an old community, it is easily affected by the ground flatness in the green belt, making it impossible to guarantee the safety of the maintenance personnel on the working platform. A kind of outdoor power maintenance rack disclosed in the publication number CN106099725B can be applicable to maintenance operations under uneven ground conditions, but there is a problem that when it is necessary to repair the power equipment adjacent to the current power equipment, the operators need to get off the ladder, move the ladder to a suitable position and then climb the ladder again, resulting in an increase in operation time;

[0004] Therefore, a foldable power automation maintenance rack with high safety is proposed. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a foldable power automation maintenance rack with high safety, which solves the problems that when the existing maintenance rack is used and moved, the maintenance personnel need to get off the ladder, move it and then climb again, and the movable maintenance rack is supported by wheels and is greatly affected by the terrain, making it impossible to guarantee the safety of the maintenance personnel on the rack during the movement process.

[0013] Preferably, an air delivery pipe is communicated with the extension airbag, one end of the air delivery pipe is communicated with an air pump, and the air pump is fixed inside the motor cover.

[0014] Preferably, a grass separating plate is slidably inserted into the fixed rod. A second spring is installed between one end of the grass separating plate and the top of the fixed rod. The grass separating plate is arrow-shaped, and a sliding rod for adjusting the walking component is slidably inserted into the grass separating plate.

[0015] Preferably, one end of the sliding rod close to the grass dividing board is arc-shaped. A guiding column is slidably inserted into the sliding rod. An installation rod is fixed to the top of the guiding column. One end of the installation rod is magnetically attracted to the side wall of the bottom plate.

[0016] Preferably, a third spring is fixed to the bottom of the installation rod. The other end of the third spring is fixed to a power rod. A lower adjusting rod is fixed to the bottom of the power rod. A lower control switch is arranged directly below the lower adjusting rod. An upper adjusting rod is fixed to the top of the power rod. An upper control switch is arranged directly above the upper adjusting rod.

[0017] Preferably, there are two bottom plates. The two bottom plates are limited by a limiting plate. The number of the power motors is adapted to the bottom plates.

[0018] The present invention provides a foldable electric power automation maintenance rack with high safety. Compared with the prior art, it has the following beneficial effects:

[0019] (1) For the foldable electric power automation maintenance rack with high safety, by setting a climbing frame, an operation platform, a blocking block, a guardrail, an intercepting rope, a locking block, a bottom plate, a connecting block, a supporting leg, and a fixing block, when it is necessary to use the maintenance rack to maintain electric power equipment, maintenance personnel carry the parts of the maintenance rack from the substation to the electric power equipment to be maintained by a maintenance vehicle, assemble each part together to form a maintenance rack, change the four-point support of the inclined climbing frame to the four-point support of the vertical bottom plate, improve the stability of the support, make the maintenance operation safer, and after the maintenance operation is completed, by removing the climbing frame from the bottom plate and separating the two operation platforms, the operation platforms can be bent to reduce the storage space required. Further, the guardrail can be replaced with a detachable one to further reduce the storage space.

[0020] (2) For the foldable electric power automation maintenance rack with high safety, by setting a power motor, a rotating shaft, a gear, a rack, a side guiding rod, a side guiding sleeve, a first spring, an upper guiding rod, an electric push rod, a magnet, an expansion plate, an expansion air bag, an air pipe, and an air pump, when it is necessary to move the maintenance rack to maintain electric power equipment, there is no need to go down the ladder, move the ladder to a suitable position and then go up the ladder again to operate, which is time-consuming. The whole maintenance rack is driven to move by the walking component on the bottom plate. At the same time, the expansion plate will not directly contact with gravel, steps or potholes, so that when the maintenance rack passes by, the whole will not have an angular deviation. This not only increases the safety of the maintenance personnel standing on the operation platform, but also increases the application scenarios of the maintenance rack, enables the maintenance rack to operate under different working conditions, and can be folded and placed to reduce the storage space required.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 to 12 , the present invention provides the following technical solutions:

[0037] Embodiment 1: A highly safe foldable electric power automation maintenance rack, including a working platform 101 for maintenance personnel to stand on, a climbing frame 1 movably installed at the bottom of the working platform 101 through a movable shaft for maintenance personnel to climb, a guardrail 103 fixedly installed at one end of the top of the working platform 101, and an intercepting rope 104 hung on the guardrail 103 through a safety buckle. The numbers of the climbing frame 1, the working platform 101, the guardrail 103, and the intercepting rope 104 are all two. A fixed block 105 is slidably installed in one of the working platforms 101, and a fixed slot adapted to the fixed block 105 is opened in the other working platform 101. A set of blocking blocks 102 for restricting the tilting angle of the climbing frame 1 are installed on the outer walls of the two working platforms 101. A connecting block 21 is slidably installed in each of the two climbing frames 1. The bottoms of the two connecting blocks 21 are fixedly installed on the top of the same bottom plate 2. A locking block 106 for limiting is correspondingly inserted into each of the two climbing frames 1 and the two connecting blocks 21. Four uniformly distributed support legs 22 are fixedly installed at the bottom of the bottom plate 2.

[0038] During use, when it is necessary to use the maintenance rack to repair power equipment, the maintenance personnel carry the maintenance rack parts from the substation building to the power equipment to be repaired through the maintenance vehicle. After carrying the various maintenance rack parts out of the maintenance vehicle compartment, one of the working platforms 101 is slid into another working platform 101. When the sides of the two working platforms 101 are aligned, the fixing block 105 just slides to the fixing groove opened in one of the working platforms 101, and thus slides down from this working platform 101 into the fixing groove under the action of gravity to limit the space between the two working platforms 101. The blocking block 102 blocks the climbing frame 1 to prevent it from sliding outwards during climbing. The working platform 101 provides a supporting force for the guardrail 103. After the maintenance personnel climb onto the working platform, hanging the intercepting rope 104 can close the space between the working platforms, preventing the two working platforms 101 from separating from each other when the maintenance personnel stand on the combined working platform 101 for maintenance operations and causing the maintenance personnel to fall, thus improving the safety of maintenance operations;

[0039] Whether to assemble the bottom plate 2 can be selected according to the bottom support conditions of the power equipment to be repaired. If the ground under the bottom of the power equipment is slippery, the bottom plate 2 can be assembled. If the ground friction under the bottom of the power equipment is large, it can be selected not to assemble the bottom plate 2. When assembling the bottom plate 2, the bottoms of the two climbing frames 1 are snapped into the connecting block 21, and the locking block 106 is used to lock between the climbing frame 1 and the connecting block 21 to prevent the climbing frame 1 from sliding out of the bottom plate 2 during use and causing the whole maintenance rack to tip over. The support legs 22 provide a supporting force for the bottom plate 2, and the bottom plate 2 provides a supporting force for the assembled climbing frame 1 and the working platform 101, changing the inclined four-point support of the climbing frame 1 to the vertical four-point support of the bottom plate 2, improving the stability of the support and making the maintenance operation safer. After the maintenance operation is completed, by removing the climbing frame 1 from the bottom plate 2 and separating the two working platforms 101, the working platform 101 can be bent to reduce the storage space required. Further, the guardrail 103 can be replaced with a detachable one, and the climbing frame 1 can be replaced with a telescopic one to further reduce the storage space.

[0040] Embodiment 2. The technical solution of this embodiment different from that of Embodiment 1 includes: 1. A walking component for moving on uneven ground is arranged below the climbing frame 1. The walking component includes: a power motor 23, a rotating shaft 24, a gear 25, a rack 26, a side guide rod 27, a side guide sleeve 28, a first spring 29, an upper guide rod 210, an electric push rod 211, a magnet 212, an extension plate 3, an extension airbag 31, an air delivery pipe 32, an air pump 33;

[0041] The power motor 23 is a double-shaft motor. The bottom of the power motor 23 is fixedly installed at the bottom of the bottom plate 2 through a motor cover to provide power for the walking assembly. A rotating shaft 24 is fixedly installed on the output end of the power motor 23 through a coupling. A gear 25 is fixedly installed at both ends of the rotating shaft 24. A rack 26 is respectively meshed with the two gears 25. Two upper guide rods 210 are fixedly installed at the tops of the two racks 26. One ends of the four upper guide rods 210 are slidably inserted into the bottom plate 2.

[0042] One end of the side guide rod 27 is fixedly installed on the side wall of the rack 26 to guide the rack 26. A side guide sleeve 28 is slidably sleeved outside the side guide rod 27. The bottom of the side guide sleeve 28 is fixedly installed at the top of the extension plate 3. An extension airbag 31 is sleeved outside the extension plate 3. A first spring 29 is fixedly installed at the bottom of the side guide rod 27. The other end of the first spring 29 is fixedly installed at the top of the extension plate 3. Two magnets 212 are magnetically connected to the tops of the two extension plates 3 correspondingly. Four electric push rods 211 are fixedly installed at the tops of the four magnets 212. One ends of the four electric push rods 211 are fixedly installed at the bottom of the bottom plate 2. An air pipe 32 is communicated with the extension airbag 31. One end of the air pipe 32 is communicated with an air pump 33. The bottom of the air pump 33 is fixedly installed in the motor cover.

[0043] During use, when it is necessary to check the circuit when repairing power equipment with the assembled maintenance rack, there is no need to go down to the ground. Moving the maintenance rack to a suitable position and then climbing the ladder again is time-consuming. The whole maintenance rack is driven to move through the walking assembly on the bottom plate 2. The power motor 23 drives the rotating shaft 24 to rotate. The rotating shaft 24 drives the gear 25 to rotate. The gear 25 drives the rack 26 to move. The rack 26 drives the side guide rod 27 to move. The side guide rod 27 drives the side guide sleeve 28 to move. The side guide sleeve 28 drives the extension plate 3 to move. The extension plate 3 drives the extension airbag 31 to move, so that the extension plate 3 extends out of the bottom plate 2. When one end of the side wall of the side guide sleeve 28 contacts the magnet 212, the power motor 23 stops rotating. At the same time, the electric push rod 211 starts to drive the magnet 212 to move. The magnet 212 drives the extension plate 3 to move. The extension plate 3 jacks up the whole bottom plate 2. When the support leg 22 no longer provides support force for the bottom plate 2, the electric push rod 211 stops. The power motor 23 starts to drive the rotating shaft 24 to rotate in the reverse direction, so that the rotating shaft 24 drives the gear 25 to rotate. The gear 25 moves along the rack 26. The rack 26 and the upper guide rod 210 provide support force for each other. The upper guide rod 210 and the bottom plate 2 are slidably matched. When the gear 25 rotates, it can drive the rotating shaft 24, the motor cover, and the bottom plate 2 to move linearly along the rack 26 until moving to Figure 2When in the state shown, the power motor 23 stops again, and then the electric push rod 211 starts and drives the expansion plate 3 to contract towards the side where the bottom plate 2 is located through the magnet 212 until the support leg 22 touches the ground again, and reciprocates to drive the entire overhaul frame to move linearly;

[0044] When about to move, start the air pump 33. The air pump 33 transports gas into the expansion airbag 31 through the air delivery pipe 32, causing the expansion airbag 31 to expand by a certain volume. During the process of the entire overhaul frame moving forward, if there are gravel, steps or potholes on the ground;

[0045] The gravel or steps will squeeze the expansion airbag 31, causing the squeezed part of the expansion airbag 31 to contract and other parts to expand, forming a flat contact surface;

[0046] When passing through a pothole, the flat road surface will squeeze the expansion airbag 31, causing the gas in the expansion airbag 31 to gather towards the pothole, forming a flat contact surface, thereby improving the safety of the entire overhaul frame during the moving overhaul process. The expansion plate 3 will not directly contact the gravel, steps or potholes, resulting in the situation that the entire overhaul frame deflects at an angle when passing through, increasing the safety of the maintenance personnel standing on the operation platform.

[0047] Embodiment 3. The technical solution of this embodiment different from that of Embodiment 2 includes: An auxiliary component for adjusting the walking component is provided below the climbing frame 1. The auxiliary component includes: a fixed rod 4, a second spring 41, a grass separating plate 42, a sliding rod 43, a guiding column 44, a mounting rod 45, a third spring 46, a power rod 47, a lower adjusting rod 48, a lower control switch 49, an upper adjusting rod 481, and an upper control switch 491;

[0048] One end of the fixed rod 4 is fixedly installed on the top of the expansion plate 3. A grass separating plate 42 is slidably inserted into the fixed rod 4. A second spring 41 is installed between one end of the grass separating plate 42 and the top of the fixed rod 4. The grass separating plate 42 is arrow-shaped. A sliding rod 43 for adjusting the walking component is slidably inserted into the grass separating plate 42. One end of the sliding rod 43 close to the grass separating plate 42 is circularly arranged. A guiding column 44 is slidably inserted into the sliding rod 43. The top of the guiding column 44 is fixedly installed with a mounting rod 45. One end of the mounting rod 45 is magnetically attracted to the side wall of the bottom plate 2. A third spring 46 is fixedly installed at the bottom of the mounting rod 45. The other end of the third spring 46 is fixedly installed with a power rod 47. A lower adjusting rod 48 is fixedly installed at the bottom of the power rod 47. A lower control switch 49 is arranged directly below the lower adjusting rod 48. An upper adjusting rod 481 is fixedly installed at the top of the power rod 47. An upper control switch 491 is arranged directly above the upper adjusting rod 481.

[0049] During use, when starting the power motor 23 to drive the overall movement of the maintenance frame, the extension plate 3 provides a supporting force to the fixed rod 4, the fixed rod 4 provides a supporting force to the second spring 41 and the grass dividing plate 42. One end of the bottom plate 2 is magnetically attracted to the mounting rod 45, the mounting rod 45 provides a supporting force to the guide post 44, and the guide post 44 provides a supporting force to the sliding rod 43. Through the sliding fit between the sliding rod 43 and the grass dividing plate 42 and the sliding fit between the sliding rod 43 and the guide post 44, when the walking assembly is moving, when the extension plate 3 encounters green grass, surface gravel, potholes, or steps on its moving path, the sliding rod 43 can move linearly along the guide post 44;

[0050] When encountering steps, the sliding rod 43 can move upward under the extrusion of the steps and then pop downward under the action of the third spring 46 until it touches the ground. When encountering a pothole, the sliding rod 43 can pop downward under the action of the third spring 46 until it touches the bottom of the pothole and then move upward again as the walking assembly moves;

[0051] During the process, when the sliding rod 43 drives the power rod 47 to move downward synchronously, the power rod 47 drives the lower adjusting rod 48 to move, and the lower adjusting rod 48 squeezes the control button of the lower control switch 49 to start, so that the air pump 33 fills the expansion airbag 31 with gas. After the expansion airbag 31 is filled with gas, its deformation can adapt to the size of the pothole, providing stable support to the extension plate 3. When the lower adjusting rod 48 separates from the control button of the lower control switch 49, the control button of the lower control switch 49 resets under its own elastic force;

[0052] During the process, when the sliding rod 43 drives the power rod 47 to move upward synchronously, the power rod 47 drives the upper adjusting rod 481 to move, and the upper adjusting rod 481 squeezes the control button of the upper control switch 491 to start, so that the expansion airbag 31 discharges air. When the discharged expansion airbag 31 deforms when contacting gravel or steps, the amount of deformation will not be too large, resulting in an angular offset of the overall contact surface between the expansion airbag 31 and the ground. At the same time, it avoids the situation where the sharp gravel causes the expansion airbag 31 to rupture;

[0053] The grass dividing plate 42 with an arrow shape breaks the green grass encountered during the movement. The second spring 41 provides an elastic force to the grass dividing plate 42, so that the grass dividing plate 42 can still stick to the ground when the extension plate 3 is suspended. This avoids the angular offset of the overall contact surface between the extension plate 3 and the ground due to the different growth conditions of the grass in the green grass during the process of the walking assembly driving the extension plate 3 to move. At the same time, when the root of the grass is relatively hard, the grass dividing plate 42 can make a small displacement under the action of the second spring 41 to avoid this place.

[0054] In another embodiment, the installation positions and shapes of the fixed rod 4, the mounting rod 45, the upper control switch 491, the lower control switch 49, the lower adjusting rod 48, and the upper adjusting rod 481 are adjusted so that they are all located between the fixed rod 4 and the sliding rod 43. The upper control switch 491 and the lower control switch 49 are both fixedly installed on the side wall of the fixed rod 4. At the same time, the bottom of the mounting rod 45 is fixedly installed on the top of the fixed rod 4.

[0055] In another embodiment, the grass dividing board 42 is set as a steel strip with a certain elasticity, so that when the extension board 3 moves and encounters the impact force generated by the gravel on the ground, the gravel can be swept out of the traveling route of the extension board, improving the safety of the overall maintenance frame during the process. At the same time, one end of the grass dividing board 42 away from the extension board 3 is tilted upward and has a certain arc, so as to smoothly pass through some gravel or steps buried in the soil.

[0056] In another embodiment, the bottom plate 2 is also divided into two pieces. The two bottom plates 2 are limited by the limiting plate 5, and the power motor 23 is replaced with two independent motors. The position of the air pump 33 is adjusted so that after the maintenance operation is completed, after removing the climbing frame 1, the operation platform 101, and the bottom plate 2, the climbing frame 1, the operation platform 101, and the bottom plate 2 can all be folded and stored, reducing the space required for storage.

[0057] In another embodiment, two air pumps 33 are also provided. The two air pumps 33 supply air to the expansion air bags 31 on both sides respectively. A set of upper adjusting rods 481, upper control switches 491, lower adjusting rods 48, and lower control switches 49 are provided on both sides of the bottom plate 2, so that the expansion air bags 31 on both sides can be adaptively adjusted according to different situations on both sides.
