Description

Technical Field

[0001] The invention relates to the technical field of electric power maintenance, in particular to a foldable electric power automation maintenance frame with high safety. Background Art

[0002] At present, in order to meet the needs of all aspects, my country's electric power industry is in a stage of vigorous development. Therefore, the construction and maintenance of power equipment generally have the characteristics of tight schedule and heavy tasks. In addition, there are many dangerous points at the power maintenance construction site, and the working environment often changes. This includes the power equipment in old communities. These devices are usually first-generation products with a long service life due to their early installation time and technical limitations, and the probability of failure is high. These power equipment are usually installed in the green belts of the community. When such power equipment fails and needs to be repaired and needs to be climbed, a maintenance rack or a ladder truck 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 operator needs to get off the ladder, move the ladder to a suitable position, and then go up again to work, which increases the working time. Although the ladder truck can move within a certain range to shorten the working time, it is greatly affected by the maintenance space and is easily restricted by the lines and building distances in the old community. In the process of transfer, not only the ladder but also the car need to be moved, which increases the working time. There are also movable maintenance racks, but most of them are supported by wheels and are greatly affected by the terrain, so the safety of the maintenance personnel on the rack cannot be guaranteed during the movement. For example, a new type of power maintenance rack disclosed in announcement number CN206323049U is supported by wheels, which is greatly affected by the terrain. If the operation is carried out in an old residential area, it is easily affected by the flatness of the ground in the green belt, so that the safety of the maintenance personnel on the working platform cannot be guaranteed. A field power maintenance rack disclosed in announcement number CN106099725B can be used for 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 operator needs to get off the ladder, move the ladder to a suitable position, and then go up the ladder again to work, which increases the working time; Therefore, a foldable electric power automation maintenance frame with high safety is proposed. Summary of the invention

[0013] The present invention provides a foldable electric power automation maintenance frame with high safety. Compared with the prior art, it has the following beneficial effects: (1) The highly safe foldable electric automation maintenance frame is provided with a climbing frame, an operating platform, a blocking block, a guardrail, an intercepting rope, a locking block, a base plate, a connecting block, a supporting leg, and a fixing block. When the maintenance frame is needed to perform maintenance on the electric equipment, the maintenance personnel carry the maintenance frame parts from the station building to the electric equipment to be maintained by a maintenance vehicle, assemble the parts together to form the maintenance frame, and change the inclined four-point support of the climbing frame to a vertical four-point support of the base plate, thereby improving the stability of the support and making the maintenance work safer. After the maintenance work is completed, the climbing frame can be removed from the base plate and the two operating platforms can be separated so that the operating platform can be bent to reduce the storage space required.

When the maintenance frame is used to repair the electric equipment and needs to be moved, there is no need to get off the ladder, move the ladder to a suitable position, and then go up the ladder again to work, which wastes time. The maintenance frame is driven to move as a whole through the walking assembly on the bottom plate. At the same time, the expansion plate will not directly contact with gravel, steps or potholes, causing the maintenance frame to shift in angle as a whole when passing by. This not only increases the safety of maintenance personnel standing on the working platform, but also increases the application scenarios of the maintenance frame, so that the maintenance frame can operate under different working conditions and can be folded and placed, reducing the space required for storage.

[0015] (3) The foldable electric automation maintenance frame with high safety is provided with a fixed rod, a second spring, a grass dividing plate, a sliding rod, a guide column, a mounting rod, a third spring, a power rod, a lower adjustment rod, a lower control switch, an upper adjustment rod, an upper control switch, and a limit plate. When the power motor is started to drive the overall movement of the maintenance frame, the sliding rod and the grass dividing plate slide together, and the sliding rod and the guide column slide together. When the walking component encounters green grass, surface gravel, potholes, and steps on the moving path of the expansion plate during the movement process, the expansion degree of the expansion airbag can be adaptively adjusted to avoid the expansion airbag from over-expanding or under-expanding, causing the support surface to tilt and causing the support to be unstable, thereby improving the stability, automation, and safety of the overall movement of the maintenance frame.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 12 , the present invention provides the following technical solutions: Embodiment 1: A foldable electric automation maintenance frame with high safety, comprising a work platform 101 for maintenance personnel to stand on, a climbing frame 1 movably mounted at the bottom of the work platform 101 through a movable shaft for maintenance personnel to climb, a guardrail 103 fixedly mounted at one end on the top of the work platform 101, and an interception rope 104 hung on the guardrail 103 through a safety buckle, the climbing frame 1, the work platform 101, the guardrail 103, and the interception rope 104 are all in two pieces, one of which is slidably mounted in the work platform 101. 105, a fixing groove matched with the fixing block 105 is opened in the other working platform 101, a group of blocking blocks 102 for limiting the inclination 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 base plate 2, a locking block 106 for limiting is correspondingly inserted in the two climbing frames 1 and the two connecting blocks 21, and four evenly distributed supporting legs 22 are fixedly installed at the bottom of the base plate 2.

[0020] When the maintenance rack is needed to repair the power equipment, the maintenance personnel carry the maintenance rack parts from the station to the power equipment to be repaired by the maintenance vehicle. After the maintenance rack parts are moved down from the maintenance vehicle, one of the work platforms 101 is slid into the other work platform 101. When the sides of the two work platforms 101 are aligned, the fixing block 105 just slides to the fixing groove provided in one of the work platforms 101, so that the work platform 101 slides out of the work platform 101 under the action of gravity. The climbing frame 101 is blocked by the blocking block 102 to prevent sliding outwards during climbing. The working platform 101 provides support for the guardrail 103. After the maintenance personnel climb to the working platform, the interception rope 104 is hung to close the working platforms, so as to prevent the two working platforms 101 from separating from each other when the maintenance personnel stand on the combined working platform 101 to perform maintenance work, causing the maintenance personnel to fall, thereby improving the safety of the maintenance work; 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 at the bottom of the power equipment is slippery, the bottom plate 2 can be assembled. If the ground friction at the bottom of the power equipment is large, the bottom plate 2 can be selected not to be assembled. When assembling the bottom plate 2, the bottoms of the two climbing frames 1 are inserted into the connecting block 21, and the locking block 106 is used to lock the climbing frame 1 and the connecting block 21 to prevent the climbing frame 1 from sliding off the bottom plate 2 during use and causing the maintenance frame to fall over as a whole. The supporting legs 22 provide support to the bottom plate 2, and the bottom plate 2 is provided with support force. The plate 2 provides support for the assembled climbing frame 1 and the working platform 101, and changes the inclined four-point support of the climbing frame 1 to the vertical four-point support of the base plate 2, thereby improving the stability of the support and making the maintenance work safer. After the maintenance work is completed, the climbing frame 1 can be removed from the base plate 2 and the two working platforms 101 can be separated, and the working platform 101 can be bent to reduce the space required for storage. The guardrail 103 can be further replaced with a detachable one, and the climbing frame 1 can be replaced with a retractable one to further reduce the storage space.

[0021] Embodiment 2, the technical solutions of this embodiment are different from those of Embodiment 1 and include: 1. A walking assembly for moving on uneven ground is arranged below the climbing frame 1, and the walking assembly 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 spring 29, an upper guide rod 210, an electric push rod 211, a magnet 212, an expansion plate 3, an expansion airbag 31, an air pipe 32, and an air pump 33; The power motor 23 is a dual-axis motor. The bottom of the power motor 23 is fixedly mounted on the bottom of the base plate 2 through a motor cover to provide power to the walking assembly. A rotating shaft 24 is fixedly mounted on the output end of the power motor 23 through a coupling. A gear 25 is fixedly mounted on both ends of the rotating shaft 24. A rack 26 is meshed with each of the two gears 25. Two upper guide rods 210 are fixedly mounted on the tops of the two racks 26. One end of the four upper guide rods 210 is slidably penetrated in the base plate 2. One end of the side guide rod 27 is fixedly mounted on the side wall of the rack 26 for guiding 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 mounted on the top of the expansion plate 3, an expansion airbag 31 is arranged outside the expansion plate 3, a spring 29 is fixedly mounted on the bottom of the side guide rod 27, the other end of the spring 29 is fixedly mounted on the top of the expansion plate 3, the tops of the two expansion plates 3 are magnetically connected to two magnets 212, four electric push rods 211 are fixedly mounted on the tops of the four magnets 212, one end of the four electric push rods 211 are fixedly mounted on the bottom of the base plate 2, an air pipe 32 is connected to the expansion airbag 31, one end of the air pipe 32 is connected to an air pump 33, and the bottom of the air pump 33 is fixedly mounted in the motor cover.

[0022] When in use, when the assembled inspection frame is used to repair the power equipment and the line needs to be checked, there is no need to go down to the ground, move the inspection frame to a suitable position and then go up the ladder again to work, which wastes time. The inspection frame is driven to move as a whole by the walking assembly on the bottom plate 2, and the rotating shaft 24 is driven to rotate by the power motor 23, and the rotating shaft 24 drives the gear 25 to rotate, and the gear 25 drives the rack 26 to move, and the side guide rod 27 is driven to move by the rack 26, and the side guide rod 27 drives the side guide sleeve 28 to move, and the side guide sleeve 28 drives the expansion plate 3 to move, and the expansion plate 3 drives the expansion airbag 31 to move, so that the expansion plate 3 extends outward from the bottom plate 2, and the side wall of the side guide sleeve 28 is connected with the magnet 21 2, the power motor 23 stops rotating, and the electric push rod 211 starts to drive the magnet 212 to move, and the magnet 212 drives the expansion plate 3 to move, and the expansion plate 3 lifts up the bottom plate 2 as a whole, so that the support leg 22 no longer provides support force to the bottom plate 2. When the electric push rod 211 stops, the power motor 23 starts to drive the rotating shaft 24 to rotate in the opposite direction, so that the rotating shaft 24 drives the gear 25 to rotate, and the gear 25 moves along the rack 26. The rack 26 and the upper guide rod 210 provide support force to each other, and the upper guide rod 210 and the bottom plate 2 are slidably matched, so that when the gear 25 rotates, it can drive the rotating shaft 24, the motor cover, and the bottom plate 2 to move in a straight line along the rack 26 until it moves to Figure 2In the state shown, the power motor 23 stops again, and then the electric push rod 211 starts and drives the expansion plate 3 to retract toward the side close to the bottom plate 2 through the magnet 212 until the support leg 22 touches the ground again, thereby reciprocatingly driving the maintenance frame as a whole to move linearly; When the maintenance rack is about to move, the air pump 33 is started, and the air pump 33 delivers gas into the expansion airbag 31 through the air delivery pipe 32, so that the expansion airbag 31 expands to a certain volume. When the maintenance rack is moving as a whole, if there are gravels, steps or potholes on the ground; The gravel or steps will squeeze the expansion airbag 31, causing the squeezed part of the expansion airbag 31 to shrink and the other parts to expand, thus forming a flat contact surface; 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 at the pothole to form a flat contact surface, thereby improving the safety of the entire maintenance frame during the mobile maintenance process. The expansion plate 3 will not directly contact gravel, steps or potholes, causing the overall angle of the maintenance frame to shift when passing by, thereby increasing the safety of maintenance personnel standing on the work platform.

[0023] Embodiment 3, the technical solution of this embodiment is different from that of embodiment 2 in that: an auxiliary component for adjusting the walking component is arranged below the climbing frame 1, and the auxiliary component includes: a fixed rod 4, a second spring 41, a grass dividing plate 42, a sliding rod 43, a guide column 44, a mounting rod 45, a third spring 46, a power rod 47, a lower adjustment rod 48, a lower control switch 49, an upper adjustment rod 481, and an upper control switch 491; One end of the fixed rod 4 is fixedly installed on the top of the expansion plate 3, and a grass dividing plate 42 is slidably inserted into the fixed rod 4, and a spring 2 41 is installed between one end of the grass dividing plate 42 and the top of the fixed rod 4, and the grass dividing plate 42 is set in an arrow shape, and a sliding rod 43 for adjusting the walking component is slidably inserted into the grass dividing plate 42, and the sliding rod 43 is set in an arc shape near one end of the grass dividing plate 42, and a guide column 44 is slidably inserted into the sliding rod 43, and a mounting rod 45 is fixedly installed on the top of the guide column 44, and one end of the mounting rod 45 is magnetically attracted to the side wall of the bottom plate 2, and a spring 3 46 is fixedly installed on the bottom of the mounting rod 45, and a power rod 47 is fixedly installed on the other end of the spring 3 46, and a lower adjusting rod 48 is fixedly installed on the bottom of the power rod 47, and a lower control switch 49 is set directly below the lower adjusting rod 48, and an upper adjusting rod 481 is fixedly installed on the top of the power rod 47, and an upper control switch 491 is set directly above the upper adjusting rod 481.

[0024] During use, when the power motor 23 is started to drive the overall movement of the inspection frame, the expansion plate 3 provides support for the fixed rod 4, the fixed rod 4 provides support for the spring 2 41 and the grass dividing plate 42, and the bottom plate 2 is magnetically attracted to one end of the mounting rod 45, the mounting rod 45 provides support for the guide column 44, and the guide column 44 provides support for the sliding rod 43. Through the sliding cooperation between the sliding rod 43 and the grass dividing plate 42, and the sliding cooperation between the sliding rod 43 and the guide column 44, when the walking component is moving, when the moving path of the expansion plate 3 encounters green grass, surface gravel, potholes, and steps, the sliding rod 43 can move in a straight line along the guide column 44; When encountering a step, the sliding rod 43 can move upward under the pressure of the step, and then pop up downward under the action of the spring 3 46 until it touches the ground. When encountering a pothole, the sliding rod 43 can pop up downward under the action of the spring 3 46 until it touches the bottom of the pothole and move upward again with the movement of the walking assembly. During the process, when the power rod 47 is driven to move downward synchronously by the sliding rod 43, the power rod 47 drives the lower adjustment rod 48 to move, and the lower adjustment rod 48 squeezes the control button of the lower control switch 49 to start, so that the air pump 33 replenishes gas into the expansion airbag 31, so that the expansion airbag 31 after replenishing gas can adapt to the size of the pit after deformation, providing stable support for the expansion board 3, and when the lower adjustment rod 48 is separated from the control button of the lower control switch 49, the control button of the lower control switch 49 is reset under the action of its own elastic force; During the process, when the sliding rod 43 drives the power rod 47 to move upward synchronously, the power rod 47 drives the upper adjustment rod 481 to move, and the upper adjustment rod 481 squeezes the control button of the upper control switch 491 to start, so that the expansion airbag 31 exhausts gas outward, so that when the expansion airbag 31 after exhausting gas contacts with gravel or steps and deforms, the deformation amount will not be too large to cause the angle deviation of the contact surface between the expansion airbag 31 and the ground as a whole, and the situation that the expansion airbag 31 is broken due to sharp gravel is avoided; The grass dividing board 42 arranged in an arrow shape is used to break up the green grass encountered during the movement, and the spring 2 41 provides elastic force to the grass dividing board 42, so that the grass dividing board 42 can still stick to the ground when the expansion board 3 is suspended in the air, to avoid the angle deviation of the contact surface between the expansion board 3 and the ground as a whole due to the different growth of grass in different parts of the green grass when the walking component drives the expansion board 3 to move. At the same time, when the root of the grass is harder, the grass dividing board 42 can be slightly displaced under the action of the spring 2 41 to avoid it.

[0025] 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 adjustment rod 48, and the upper adjustment 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 mounted on the side wall of the fixed rod 4, and the bottom of the mounting rod 45 is fixedly mounted on the top of the fixed rod 4.

[0026] In another embodiment, the grass dividing plate 42 is configured as a steel bar with a certain elasticity, so that when the expansion plate 3 encounters gravel on the ground during movement, the impact force generated can sweep the gravel out of the expansion plate's travel route, thereby improving the overall safety of the maintenance frame during operation. At the same time, the end of the grass dividing plate 42 away from the expansion plate 3 is tilted upward and has a certain curvature, so that it can smoothly pass through gravel or steps that are partially buried in the ground.

[0027] In another embodiment, the base plate 2 is also divided into two parts, and the two base plates 2 are limited by a limit plate 5, and the power motor 23 is replaced with two independent motors, and the position of the air pump 33 is adjusted, so that after the maintenance work is completed, the climbing frame 1, the working platform 101, and the base plate 2 can be dismantled, and the climbing frame 1, the working platform 101 and the base plate 2 can all be folded and stored to reduce the space required for storage.

[0028] In another embodiment, two air pumps 33 are also provided, and the two air pumps 33 supply air to the expansion airbags 31 on both sides respectively. A group of upper adjustment rods 481, upper control switches 491, lower adjustment rods 48 and lower control switches 49 are provided on both sides of the bottom plate 2, so that the expansion airbags 31 on both sides can be adaptively adjusted according to different conditions on both sides.
