Description

Technical Field

[0001] This utility model relates to the field of power climbing equipment technology, specifically a power climbing device. Background Technology

[0002] Existing power line aerial work platforms typically use a lifting mechanism to raise and lower the work platform, allowing workers to reach the appropriate height for operations. These platforms are generally surrounded by protective fencing, with an entrance on one side for workers to enter and exit. However, this entrance is usually quite large and lacks a door or barrier, posing a significant safety hazard as personnel or tools may accidentally fall through.

[0003] In addition, due to the limitations of the main structure of the elevator, even when the work platform is in the lowest descending position, there is still a certain height difference between the bottom of the platform and the ground. This height difference makes it inconvenient for workers to get on or off the work platform, especially when moving equipment, carrying tools, or frequently going up and down the platform. This not only increases the difficulty of operation but also affects work efficiency. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides an electric climbing device.

[0005] The technical solution of this utility model is as follows: An electric climbing device includes a lift and a work platform mounted thereon. The work platform is equipped with a fence with an entrance. The fence includes a guardrail and a protective plate surrounding the lower part of the outer side of the guardrail. Vertically arranged slide rails are symmetrically arranged on both sides of the entrance. A first connector is provided at the lower part of the slide rail. The first connector passes through the slide rail and is connected to the protective plate. The upper part of the slide rail is detachably connected to the upper part of the guardrail through a second connector. The entrance is also equipped with a ladder, with each side of the ladder sliding to a corresponding slide rail. The top of the ladder has sliders on both sides that are adapted to the slide rails. Each slider has a locking unit, which includes a limiting member that is movably connected to the slider. The limiting member can overlap the top surface of the slide rail.

[0006] To facilitate further limiting of the lower part of the slide rail and to facilitate the connection of the lower part of the slide rail, the lower part of the slide rail is plugged into the adjacent protective plate.

[0007] The first connector serves both to connect the lower part of the slide rail to the protective plate and to limit the slider, preventing the ladder from falling off the slide rail. To this end, the vertical distance between the side of the slider away from the ladder and the bottom surface of the slide is less than the vertical distance between the axis of the first connector and the bottom surface of the slide.

[0008] The two sides of the ladder can be partially slidable into the slide rail. The ladder slides into the slide rail mainly by sliding the slider in the slide rail. The two sides of the ladder and the slide rail are left with gaps for installing the first connector. At the same time, when the slider moves above the first connector, the first connector can limit its movement.

[0009] One way to connect the limiting component and the slider is that a central shaft is provided at the center of the upper end face of the slider in the vertical direction, the cross-section of the central shaft is a T-shaped structure, and one end of the limiting component is rotatably connected to the central shaft.

[0010] To facilitate the storage of the limiting component and to ensure that it does not interfere with the sliding of the ladder and slider on the slide rail, the length of the limiting component is greater than the width of the slide rail, and the width of the limiting component is not greater than the width of the slider.

[0011] Another way to connect the limiting component and the slider is that the upper surface of the slider is higher than the top surface of the ladder, and a through hole is opened on the upper part of the slider, and the limiting component slides into the through hole.

[0012] To prevent the limiting component from sliding out of the through hole, a sliding groove is provided on the top surface of the ladder. The length direction of the sliding groove is consistent with the length direction of the through hole, and a guide rod is provided at one end of the limiting component to slide in the sliding groove.

[0013] The beneficial effects of this utility model are as follows: A vertical sliding rail and a ladder that slides along it are installed at the entrance of the fence, integrating climbing and safety protection functions into one. When the ladder is raised to the top and fixed by the limiting device, it itself constitutes a rigid barrier that can effectively close the entrance, reliably preventing workers or tools and materials from accidentally falling from the entrance, and completely eliminating the safety hazards caused by the open entrance of existing equipment. The ladder can slide smoothly down the rails. The ladder has a certain length. When the ladder slides down, it can either be reliably supported on the ground at the bottom or be higher than the ground, thus forming a stable passage from the ground to the work platform. This greatly facilitates the workers to get on and off equipment and move tools. It overcomes the disadvantages of traditional elevators where the lowest position of the work platform is still too high off the ground and it is inconvenient to get on and off. This not only improves work efficiency but also reduces safety risks during the climbing and descending process. By ingeniously designing the first connecting component, the lower part of the slide rail is fixed, and the downward limit of the slider is simultaneously limited, ensuring the stability and safety of the ladder's sliding process. The snap-fit ​​unit (limiting component) on the slider has a simple structure and is intuitive to operate. A simple rotation or sliding is all it takes to quickly switch and reliably lock the ladder between the top working position and the bottom passage position, ensuring structural stability in all states.

[0014] The slide rail is detachably connected to the existing guardrail and guard plate through the first and second connecting parts. This additional design does not require major modifications to the main structure of the work platform, making it easy to add to production or upgrade existing equipment, and has high practicality and economy. In addition, the gap design between the ladder and the slide rail avoids movement interference with the first connecting part, ensuring smooth operation. Attached Figure Description

[0016] Example 1: See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 9As shown, an electric climbing device includes a lift 1 and a work platform 2 mounted thereon. The lift 1 and the work platform 2 are existing technologies. The work platform 2 is equipped with a fence 3 having an entrance 303. The fence 3 includes a guardrail 301 and a protective plate 302 surrounding the lower part of the outer side of the guardrail 301. Vertically arranged slide rails 4 are symmetrically arranged on both sides of the entrance 303. The lower part of the slide rail 4 is provided with a first connecting member 5. The first connecting member 5 passes through the slide rail 4 and is connected to the protective plate 302. The upper part of the slide rail 4 is detachably connected to the upper part of the guardrail 301 through a second connecting member 6. The second connecting member 6 can be a hook. The hook is hung on the guardrail 301 and fixed to the guardrail 301 by bolts.

[0017] The entrance 303 is also equipped with a ladder 7. The total length of the ladder 7 is greater than the total height of the entrance 303. The two sides of the ladder 7 are respectively connected to the corresponding slide rails 4. The top of the ladder 7 is equipped with sliders 8 that are adapted to the slide rails 4. The sliders 8 are equipped with locking units. The locking units include limiting members 9 that are movably connected to the sliders 8. The limiting members 9 can overlap the top surface of the slide rails 4.

[0018] In this embodiment, a vertical slide rail 4 and a ladder 7 that slides with it are installed at the entrance 303 of the fence 3, integrating the climbing function and the safety protection function into one. When the ladder 7 is raised to the top and fixed by the limiting member 9, it itself constitutes a rigid barrier that can effectively close the entrance 303, reliably preventing workers or tools and materials from accidentally falling from the entrance 303, and completely eliminating the safety hazards caused by the open entrance 303 of the existing equipment.

[0019] See Figure 5 As shown, in order to facilitate further limiting of the lower part of the slide rail 4 and to facilitate the connection of the lower part of the slide rail 4, a slot 401 is provided on the lower part of the slide rail 4 along its length direction. The slot 401 is adapted to the protective plate 302. The lower part of the slide rail 4 is inserted and connected to the adjacent protective plate 302, and can also be used with the first connecting piece 5 to fix the lower part of the slide rail 4 on the protective plate 302.

[0020] The first connecting piece 5 serves two purposes: connecting the lower part of the slide rail 4 to the protective plate 302 and limiting the slider 8 to prevent the ladder 7 from detaching from the slide rail 4. This allows workers to quickly climb to the work platform 2 when the ladder 7 slides downwards. To this end, the vertical distance between the side of the slider 8 furthest from the ladder 7 and the bottom surface of the slide is less than the vertical distance between the axis of the first connecting piece 5 and the bottom surface of the slide. Both sides of the ladder 7 can partially slide within the slide rail 4. The sliding connection between the ladder 7 and the slide rail 4 is mainly achieved by the slider 8 sliding within the slide rail 4. Gaps are left between the sides of the ladder 7 and the slide rail for installing the first connecting piece 5. Simultaneously, the first connecting piece 5 limits the movement of the slider 8 when it moves above it.

[0021] In the above structure, the first connecting piece 5 cleverly achieves both fixing of the lower part of the slide rail 4 and limiting of the downward limit of the slider 8, ensuring the stability and safety of the ladder 7 during its sliding process. The snap-fit ​​unit (limiting piece 9) on the slider 8 has a simple structure and intuitive operation. It can quickly switch and reliably lock the ladder 7 between the top working position and the bottom passage position with just a simple rotation or sliding, ensuring the structural stability in all states.

[0022] See Figure 6 As shown, one connection method between the limiting member 9 and the slider 8 is as follows: a central shaft 10 is provided vertically at the center of the upper end face of the slider 8, and the cross-section of the central shaft 10 is a T-shaped structure. One end of the limiting member 9 is rotatably connected to the central shaft 10. To facilitate the storage of the limiting member 9 and to ensure that the limiting member 9 does not affect the sliding of the ladder 7 and the slider 8 on the slide rail 4, the length of the limiting member 9 is greater than the width of the slide rail 4, and the width of the limiting member 9 is not greater than the width of the slider 8.

[0023] Example 2: See Figure 7 and Figure 8 As shown, the difference between Embodiment 2 and Embodiment 1 lies in the connection method between the limiting member 9 and the slider 8. Due to the different connection method, the limiting member 9 in Embodiment 2 can be slightly longer than the limiting member 9 in Embodiment 1, and the slider 8 in Embodiment 2 can be slightly taller than the slider 8 in Embodiment 1, which facilitates the opening of the through hole 11. Another connection method between the limiting member 9 and the slider 8 is that the upper end surface of the slider 8 is higher than the top surface of the ladder 7, and a through hole 11 is opened in the upper part of the slider 8, with the limiting member 9 slidingly connected in the through hole 11. To prevent the limiting member 9 from sliding out of the through hole 11, a sliding groove 12 is opened on the top surface of the ladder 7, and the length direction of the sliding groove 12 is consistent with the length direction of the through hole 11. One end of the limiting member 9 is provided with a guide rod 13 that slides in the sliding groove 12.
