[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a maintenance auxiliary platform, which includes a frame 10, a support platform 20, a support member 30, and a limiting structure 40. The frame 10 has a plurality of pedals 11 spaced apart from top to bottom. The support platform 20 is hinged to the frame 10 and has a retracted position that is retracted to the frame 10 and an unfolded position that is unfolded relative to the frame 10. The support member 30 is movably connected to the frame 10 and the support platform 20 respectively. The limiting structure 40 includes a fixed limiting protrusion 41 and a movably disposed limiting member 42. The limiting member 42 is provided with a limiting groove. When the support platform 20 is in the retracted position and the unfolded position, the limiting protrusion 41 is inserted into the limiting groove.

[0027] The maintenance auxiliary platform, utilizing the technical solution of this utility model, includes a frame 10, a support platform 20, a support member 30, and a limiting structure 40. When it is necessary to disassemble electrical components, the frame 10 is placed in the power distribution room, and the support platform 20 is adjusted from a retracted position relative to the frame 10 to an unfolded position relative to the frame 10. The support member 30 supports the support platform 20 between the frame 10 and the support platform 20. The limiting protrusion 41 is inserted into the limiting groove of the limiting member 42 to limit the support platform 20 in the unfolded position. The operator can climb onto the frame 10 by stepping on multiple foot pedals 11, remove the electrical components, and place them on the support platform 20, making the support of the electrical components more stable, thereby reducing the risk of equipment falling and personnel injury in confined spaces.

[0028] In this embodiment, in order to make the maintenance auxiliary platform more stable in the power distribution room, when the support platform 20 is adjusted to the unfolded position, the front end of the support platform should be supported on the wall of the power distribution room.

[0029] Specifically, when the support platform 20 is in the retracted position, the limiting structure 40 is positioned between the frame 10 and the support member 30; when the support platform 20 is in the extended position, the limiting structure 40 is positioned between the support member 30 and the support platform 20. The frame 10 and the support platform 20 may each be provided with a limiting protrusion 41, and the support member 30 may be provided with a limiting member 42. Alternatively, the frame 10 and the support platform 20 may each be provided with a limiting member 42, and the support member 30 may be provided with a limiting protrusion 41.

[0030] In this embodiment, limiters 42 are hinged to the frame 10 and the support platform 20, respectively, and limit protrusions 41 are provided on the support member 30. This structure offers advantages such as simple structure and ease of processing and operation.

[0031] like Figure 1 As shown, the support member 30 includes a support rod, and a sliding groove 21 is provided on the support platform 20. The upper end of the support rod is slidably disposed in the sliding groove 21, and the lower end of the support rod is hinged to the frame 10. A limiting protrusion 41 is provided at the upper end of the support rod. With the above structure, the frame 10 and the support platform 20 are supported by the support rod, which has the advantages of simple structure and easy processing.

[0032] In other embodiments, the slide 21 may be provided on the frame 10.

[0033] like Figure 1 As shown, the support platform 20 includes a support plate 22 and a side plate 23 connected to the side of the support plate 22, with a slide groove 21 disposed on the side plate 23. Using the aforementioned support platform 20, electrical components can be supported using the support plate 22, and the slide groove 21 is disposed on the side plate 23, offering advantages such as simple structure and ease of processing.

[0034] like Figure 1 As shown, there are two support rods, one on each side of the support platform 20. Each side of the support platform 20 has a sliding groove 21, and the two support rods are slidably positioned within their respective grooves 21. This structure allows the support platform 20 to be supported by two support rods, making the support more stable.

[0035] In this embodiment, a reinforcing plate is also connected between the two support rods, which can not only make the movement of the two support rods more synchronized, but also strengthen the connection between them, making the support of the two support rods more stable.

[0036] like Figure 1As shown, the frame 10 includes a climbing frame 12 and a handrail frame 13 connected to the upper end of the climbing frame 12. Multiple foot pedals 11 are installed on the climbing frame 12, and a limiting member 42 is installed on the handrail frame 13. A support platform 20 is hinged to the upper end of the climbing frame 12. Using the above-described frame 10, the climbing frame 12 facilitates climbing for the operator, and the handrail frame 13 facilitates handholds for the operator, thus ensuring the operator's personal safety.

[0037] In order to enable the limiting member 42 to cooperate with the limiting protrusion 41, the limiting member 42 is set on the handrail frame 13.

[0038] like Figure 1 As shown, a vertical plate 24 is provided at the end of the support platform 20 away from the frame 10, and a limiting member 42 is hinged to the vertical plate 24. The vertical plate 24 facilitates the support platform 20 to be close to the inner wall of the power distribution room for support, and the limiting protrusion 41 can also be provided on the vertical plate 24, which has the advantage of simple structure.

[0039] like Figure 1 As shown, the upper surface of the support platform 20 is provided with two positioning plates 25. The two positioning plates 25 are spaced apart along the hinge axis of the frame 10 and the support platform 20. The inner sidewalls of the two positioning plates 25 and the upper surface of the support platform 20 together form a positioning groove. By placing electrical components in the positioning groove, the positioning groove can be used to limit the electrical components and prevent them from falling off the support platform 20.

[0040] In this embodiment, the positioning plate 25 is provided with a through groove, which can cooperate with the protrusion of the electrical component to make the electrical component more securely positioned.

[0041] like Figure 1 As shown, the limiting member 42 includes a hinged limiting hook with a limiting groove, and the limiting protrusion 41 includes a fixed limiting pin. The limiting hook can hook onto the limiting pin. The combination of the limiting hook and the limiting pin has the advantages of simple structure and easy operation.

[0042] like Figure 1 As shown, the maintenance auxiliary platform also includes a hydraulic rod 50, with both ends of the hydraulic rod 50 hinged to the support platform 20 and the frame 10, respectively, to allow the support platform 20 to switch between the retracted and deployed positions. The hydraulic rod 50 provides assistance, reduces the operator's workload, and enhances the platform's flexibility and convenience.

[0043] The support platform 20 provided in this embodiment is made of high-strength material and has good load-bearing capacity. Its surface is designed with an anti-slip texture to prevent workers or equipment from slipping during maintenance. The dimensions of the support platform 20 are rationally designed to adapt to different types of electrical distribution rooms.

[0044] The maintenance assistance platform provided in this embodiment has the following advantages:

[0045] 1) Stable positioning and cooperation mechanism

[0046] Both the unfolding and retraction positions are equipped with a stable engagement between the limiting hook and the limiting post. This mechanism can effectively prevent the device from unfolding or folding on its own, thereby significantly improving the structural stability and safety of the device and ensuring that no accidental deformation or collapse will occur during use.

[0047] 2) Foldable support platform design

[0048] The addition of a foldable support platform 20 further enhances the platform's load-bearing capacity and overall stability. The design of the support platform 20 provides additional support when unfolded, ensuring that the platform has sufficient support strength during maintenance.

[0049] 3) Retractable support rod function

[0050] The platform features a telescopic support rod design, which makes the height adjustment more flexible and can adapt to the maintenance needs of different equipment and environments. By adjusting the length of the support rod, users can use it flexibly in different scenarios.

[0051] 4) Robust connection structure

[0052] The frame 10, support platform 20, and support rod are connected by bolts to ensure the stability of the overall structure and the firmness of the connection. This design ensures that the connection between all components is tight and not easy to loosen during use, thereby improving the safety of use.

[0053] 5) Convenient storage and securing

[0054] The design takes into account the storage of the device when not in use; the folded platform occupies little space and is easy to store. This feature not only improves the convenience of the device but also meets the needs of use in environments with limited space.

[0055] 6) Enhanced security design

[0056] Safety is taken into account in the overall structure during folding and unfolding. All connections and supports are carefully designed to ensure that they will not cause injury to personnel during use, and that the device can provide sufficient protection during maintenance operations.
