Description

Technical Field

[0001] This utility model relates to the field of power engineering maintenance rack technology, and in particular to a power engineering maintenance rack. Background Technology

[0002] In the field of power engineering, maintenance racks are crucial auxiliary equipment that ensures the smooth operation of power equipment maintenance and troubleshooting. With the continuous expansion of power system coverage, the demand for maintenance of equipment such as substations, transmission lines, and distribution facilities is becoming increasingly frequent, and the work scenarios are becoming more diverse, ranging from switchgear maintenance in confined indoor spaces to high-voltage equipment maintenance in complex outdoor terrain. Maintenance racks must possess stable lifting capabilities to provide workers with a safe high-altitude working platform, while also ensuring convenient transportation to facilitate rapid transfer between different maintenance sites. Therefore, the rationality and practicality of their structural design directly affect the efficiency, safety, and equipment turnover costs of power maintenance operations. Currently, most mainstream power engineering maintenance racks on the market use a scissor lift structure as their core lifting unit. The technical principle is that a drive mechanism drives two sets of cross-distributed rotating frames to perform a scissor-like telescopic movement, thereby adjusting the height of the standing platform. To ensure the safety of workers, guardrails are usually fixed to the edges of the standing platform. These guardrails are typically rigidly connected by welding or bolts, forming a protective barrier around the platform. While some maintenance racks have detachable guardrails, they still require manual removal of bolts and insertion / removal of pins to separate the guardrails from the platform for separate storage and transportation. Furthermore, the base is generally equipped with casters or fixed supports. Casters are used for short-distance position adjustments, while fixed supports extend during operation to enhance the overall stability of the maintenance rack and prevent platform swaying from affecting operation. However, existing power engineering maintenance racks still have significant limitations in practical applications, especially in equipment transportation. Because the guardrails must always protect the standing platform, existing racks either have fixed structures that cannot retract with platform height adjustments, resulting in a fixed overall height and volume; or while they are detachable, disassembly requires additional manpower and time, and the disassembled guardrails need to be packaged separately for transport, increasing the complexity of the transportation process. This causes the guardrails to significantly increase the overall space occupied by the equipment during transportation, making it difficult to fit the loading dimensions of conventional transport vehicles and increasing the risk of collisions and scrapes with other equipment, causing deformation and damage. Furthermore, the protruding structure of the guardrails hinders loading and unloading operations, reducing transportation efficiency and significantly interfering with the cross-scenario reusability of the maintenance rack. Therefore, a new power engineering maintenance rack is proposed to address these problems. Utility Model Content

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0025] A power engineering maintenance frame, referring to Figures 1-4The system includes a base plate 1, which supports the overall weight of the maintenance frame and provides a stable foundation. A rotating plate 2 is rotatably connected to the upper surface of the base plate 1, and a rotating plate 3 is slidably connected to the upper surface of the base plate 1. A linear slide rail is provided on the upper surface of the base plate 1 corresponding to the sliding position of the rotating plate 3. The bottom of the rotating plate 3 slides horizontally through a slider in cooperation with the linear slide rail. A cylinder 4 is rotatably connected to the upper surface of the base plate 1. Cylinder 4 is a standard SC series cylinder, model SC100×500, used to provide power output to the rotating plate 3, driving it to slide along the linear slide rail. Further details are omitted here. A standing platform 6 is provided on the upper surface of the base plate 1. Platform 6 is made of non-slip patterned aluminum alloy plate, providing a standing work area for maintenance personnel. The non-slip pattern increases the friction between the personnel's feet and the platform, preventing slips. A guardrail 7 is installed on the upper surface of platform 6 to prevent maintenance personnel from approaching the edge of platform 6, achieving a safety protection effect against falls from height. A lifting assembly is installed inside platform 6 to drive the guardrail 7 to rise and fall independently, meeting the protection needs of maintenance personnel of different heights or in different work scenarios. A storage assembly is installed on the upper surface of platform 6 to store maintenance tools, achieving the effect of categorized storage and convenient access to tools. The lifting assembly includes a sliding plate 8, the upper surface of which is fixedly connected to the lower surface of the guardrail 7. A cylinder 9 is fixedly connected to the bottom of the standing platform 6. Cylinder 9 is a miniature cylinder, model MGPM20-100, used to provide power to the lifting assembly and drive the connecting rod 10 to extend and retract. (Further details omitted). The output end of cylinder 9 is fixedly connected to connecting rod 10, which transmits the power from cylinder 9. A connecting rod 11 is fixedly connected to the side wall of connecting rod 10, and is perpendicularly welded to connecting rod 10. The side wall of connecting rod 11 can rotate. A gear 12 is connected to the sliding plate 8, which has a rectangular through groove inside. A rack 13 is installed inside the sliding plate 8 to mesh with the gear 12 and transmit the transmission, converting the horizontal movement of the gear 12 into vertical movement. The rack 13 is located inside the groove and slides vertically in cooperation with the groove, thus preventing the rack 13 from deviating and ensuring meshing accuracy. The rack 13 meshes with the connecting rod 11. Through the meshing transmission between the gear 12 and the rack 13, the horizontal movement of the connecting rod 11 is converted into the vertical movement of the rack 13, thereby driving the sliding plate 8 and the guardrail 7 to rise and fall. One end of rotating plate 2 is slidably connected to the bottom of the standing platform 6. A linear slide rail is also provided at the bottom of the standing platform 6 corresponding to the sliding position of rotating plate 2. The end of rotating plate 2 slides in cooperation with the slide rail through a slider. In conjunction with the rotational connection between the other end of rotating plate 2 and the base plate 1, it rotates to ensure the smooth movement of rotating plate 2. One end of rotating plate 3 is rotatably connected to the bottom of the standing platform 6. A connecting block 5 is rotatably connected to the side wall of rotating plate 3. The connecting block 5 is used to connect the output end of cylinder 4 to rotating plate 3 and transmit the thrust of cylinder 4. The output end of cylinder 4 is fixedly connected to the side wall of connecting block 5. In conjunction with the rotational connection between connecting block 5 and rotating plate 3, the linear motion of cylinder 4 is converted into the rotational motion of rotating plate 3. Reference Figure 5 and Figure 6 The storage components include a shelf 14 and a storage box 15. The shelf 14 is used to fix the storage components to the guardrail 7 and support the storage box 15. The side wall of the shelf 14 is fixedly connected to the side wall of the guardrail 7. The side wall of the storage box 15 is fixedly connected to the upper surface of the shelf 14. The storage box 15 is used as a basic storage unit to store commonly used maintenance tools, achieving the effect of convenient storage of basic tools. A storage box 2 18 is provided at the upper end of the storage box 15 to further expand the storage space. Storage box 15 has two rotating shafts 24 rotatably connected to its side wall. The shafts 24 provide rotational support points. Each shaft 24 has a toothed plate 16 fixedly connected to its side wall. The two toothed plates 16 mesh with each other, synchronously transmitting the rotational motion of one toothed plate 16 to the other, ensuring they rotate in opposite directions. This pushes storage box 2 18 outwards. Each toothed plate 16 has a connecting plate 3 25 fixedly connected to its side wall. The connecting plate 3 25 connects the toothed plates 16 to storage box 2 18, converting the rotational motion of the toothed plates 16 into the linear motion of storage box 2 18, achieving the desired effect. The plate 16 drives the storage box 2 18 to unfold outward in an arc. One end of the connecting plate 3 25 is rotatably connected to the side wall of the storage box 2 18 to reduce the frictional resistance between the connecting plate 3 25 and the storage box 2 18 and prevent movement jamming. Both connecting plates 3 25 are rotatably connected to the side walls of the connecting strip 26. One end of the connecting strip 26 is rotatably connected to the handle 17. The surface of the handle 17 is provided with anti-slip texture for maintenance personnel to grip and apply force, so as to achieve the effect of conveniently controlling the movement of the toothed plate 16. The connecting strip 26 is used to connect the connecting plate 3 25 and the handle 17, and transmit the force applied by the handle 17 to drive the toothed plate 16 to rotate around the rotating shaft 24. A connecting plate 19 is rotatably connected to the side wall of storage box 2 18. The connecting plate 19 connects storage box 2 18 to cover plate 20, and the opening and closing of cover plate 20 is driven by the expansion and contraction of storage box 2 18. One end of the connecting plate 19 is rotatably connected to the side wall of storage box 1 15, and the other end of the connecting plate 19 is rotatably connected to cover plate 20. Cover plate 20 is used to cover the opening of storage box 2 18, which not only allows maintenance personnel to see the tools inside the box, but also achieves the effect of dust prevention and preventing tools from falling. The lower end of cover plate 20 is attached to the upper end of storage box 2 18. The storage box 21 is rotatably connected to the side wall of the storage box 21. The connecting plate 21 is used to form a symmetrical support structure with the connecting plate 19. Together with the connecting plate 19, it drives the cover 20 to move, so as to avoid the cover 20 tilting and jamming due to the force on one side, and achieve a smooth opening and closing effect. One end of the connecting plate 21 is rotatably connected to the side wall of the cover 20. A buckle 22 is fixedly connected to the upper surface of one cover 20. The buckle 22 is used to cooperate with the hook 23 to lock the cover 20. A hook 23 is fixedly connected to the upper surface of the other cover 20. The hook 23 and the buckle 22 are engaged to achieve the effect of tightly locking the two covers 20, so as to prevent the cover 20 from accidentally opening and causing tools to fall when the maintenance rack moves or shakes.

[0026] Working principle: When the height of the standing platform 6 needs to be adjusted to adapt to different maintenance positions, cylinder 4 is activated. The output end of cylinder 4 pushes the connecting block 5, which is fixedly connected to it, to move. Since the side wall of the connecting block 5 is rotatably connected to the side wall of the rotating plate 3, the connecting block 5 will drive the rotating plate 3 to move synchronously. One end of the rotating plate 2 is rotatably connected to the upper surface of the base plate 1, and the other end is slidably connected to the bottom of the standing platform 6. One end of the rotating plate 3 is slidably connected to the upper surface of the base plate 1, and the other end is rotatably connected to the bottom of the standing platform 6. The two are cross-linked. When the rotating plate 3 slides along the upper surface of the base plate 1 under the driving force of cylinder 4, it will drive the rotating plate 2 to rotate around the rotation point between it and the base plate 1, forming a scissor-like telescopic motion, thereby pushing the standing platform 6 to move up or down to achieve the adjustment of the maintenance height. By activating the cylinder 2 9 fixed at the bottom of the standing platform 6, the output end of the cylinder 2 9 drives the connecting rod 10, which is fixedly connected to it, to extend and retract. Since the side wall of the connecting rod 2 11 is fixedly connected to the side wall of the connecting rod 10, the connecting rod 10 will synchronously drive the connecting rod 2 11 to move, thereby causing the gear 12, which is rotatably connected to the side wall of the connecting rod 2 11, to move together. The upper surface of the sliding plate 8 is fixedly connected to the lower surface of the guardrail 7, and the side wall slides in cooperation with the inside of the standing platform 6. The sliding groove opened inside is used to accommodate the rack 13, and the rack 13 meshes with the gear 12. When the gear 12 moves with the connecting rod 2 11, it will drive the rack 13 to slide up and down along the sliding groove through meshing transmission. The rack 13 then pushes the sliding plate 8 to slide along the inside of the standing platform 6, ultimately realizing the raising and lowering of the guardrail 7. The protection height can be adjusted according to the height of the maintenance personnel or the needs of the work scene to enhance safety. When a tool is needed, the maintenance personnel grip the handle 17 and apply downward force. Since the handle 17 is rotatably connected to the side wall of the connecting bar 26, the handle 17 will drive the connecting bar 26 to move synchronously. The other end of the connecting bar 26 is rotatably connected to the side wall of the connecting plate 25, thereby driving the toothed plate 16 to rotate around the pivot 24 on the side wall of the storage box 15. The two toothed plates 16 are fixed to the side wall of the storage box 15 via the pivot 24, and they mesh with each other. When one toothed plate 16 rotates under the influence of the connecting bar 26, it will drive the other toothed plate 16 through the meshing relationship. One toothed plate 16 rotates synchronously in opposite directions. Both toothed plates 16 have a connecting plate 25 fixedly connected to their side walls. The other end of the connecting plate 25 is rotatably connected to the side wall of the storage box 18. When the toothed plates 16 rotate, the rotational motion is converted into linear thrust through the connecting plate 25, which pushes the storage box 18 outward along the rotation direction of the connecting plate 25, thereby expanding the storage space. If the storage box 18 needs to be retracted, the handle 17 is operated in the opposite direction, and the storage box 18 is retracted to the top of the storage box 15 through the above transmission path, reducing space occupation. During the unfolding of storage box 2 18, connecting plate 1 19 and connecting plate 2 21, which are rotatably connected to its side wall, move synchronously. One end of connecting plate 1 19 is rotatably connected to the side wall of storage box 1 15, and the other end drives the cover plate 20 to rotate around the connection point. One end of connecting plate 2 21 is rotatably connected to the side wall of storage box 2 18, and the other end pushes the cover plate 20 synchronously, causing the lower end of connecting plate 2 21 of cover plate 20 to move in the direction of rotation, thus opening the cover plate 20. When storage box 2 18 is retracted, the cover plate 20 closes. At this time, by engaging the buckle 22 on the upper surface of one cover plate 20 with the hook 23 on the upper surface of the other cover plate 20, the storage components can be locked to prevent tools from falling or dust from entering.
