[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a portable lifting frame for power failure repair, including a storage seat 1, a handle 2 is connected to the storage seat 1, support blocks 3 are connected to the four corners below the storage seat 1, a storage box 4 is connected inside the storage seat 1, a guide rod 5 is connected inside the storage seat 1, a motor 6 is installed on one side of the storage seat 1, a threaded rod 7 is connected to the output shaft of the motor 6, a fixed plate 8 is fixedly connected to one end of the threaded rod 7, a movable plate 9 is installed on the threaded rod 7, a threaded sleeve 10 is installed on the movable plate 9, and the threaded rod 7 is rotated to connect Connected in the storage seat 1, the threaded sleeve 10 is threadedly matched with the threaded rod 7, the fixed plate 8 and the movable plate 9 are connected with a connecting pin 11, and the fixed plate 8 and the movable plate 9 are provided with a through hole 26. The movable plate 9 slides on the guide rod 5 through the through hole 26. There are two guide rods 5 and they are respectively distributed on both sides of the threaded rod 7. When the motor 6 rotates the threaded rod 7, the movable plate 9 will move along the threaded rod 7, and the guide rod 5 can guide the movement of the movable plate 9, so that the movable plate 9 can move smoothly and avoid the movable plate 9 from deflecting when moving.

[0022] The fixed plate 8 is rotatably connected to the external rod 12 through the connecting pin 11, and the movable plate 9 is rotatably connected to the internal rod 13 through the connecting pin 11. The external rod 12 and the internal rod 13 intersect with each other, and the intersecting part of the external rod 12 and the internal rod 13 is penetrated by a fixing pin 23. One end of the internal rod 13 is connected to a connecting rod 24, and both ends of the connecting rod 24 are connected to sliders 25. The slider 25 slides in the slide groove 16, and the lifting platform 15 is pushed upward by the rotation of the external rod 12 and the internal rod 13, thereby raising the working height of the staff to facilitate the staff to inspect the lines and power equipment.

[0023] One end of the inner connecting rod 13 is connected to a fixed rod 14, and a lifting platform 15 is rotatably connected to the fixed rod 14. An anti-skid pad 21 is connected below the support block 3, and a rubber pad 22 is connected to the lifting platform 15. Both the anti-skid pad 21 and the rubber pad 22 are provided with anti-skid patterns. The anti-skid pad 21 increases the friction with the ground to prevent the storage seat 1 from sliding when the staff is inspecting, and the rubber pad 22 can prevent the staff from slipping, thereby improving the safety of work.

[0024] Slide grooves 16 are provided on both sides of the lifting platform 15, and a socket 17 is provided on the lifting platform 15. A guardrail 18 is plugged into the lifting platform 15 through the socket 17. A slot 19 is provided on the guardrail 18. The guardrail 18 is plugged with a side panel 20 through the slot 19. A reflective strip 27 is connected to the guardrail 18. A plug-in rod 28 is connected under the guardrail 18, and the plug-in rod 28 is plugged into the socket 17. Blocks 29 are connected on both sides of the side panel 20. The block 29 is T-shaped and plugged into the slot 19. The reflective strip 27 on the guardrail 18 warns the surrounding personnel and indicates the working position, while the guardrail 18 and the side panel 20 block the staff to prevent them from falling.

[0025] The working principle of the utility model is:

[0026] During operation, the threaded rod 7 is rotated by the motor 6, so that the movable plate 9 can move along the threaded rod 7 through the threaded sleeve 10. As the movable plate 9 moves, the inner connecting rod 13 will rotate to push the lifting platform 15, and the outer connecting rod 12 will also rotate, so that the slider 25 can slide in the slide groove 16, thereby raising the height of the lifting platform 15, so that the staff can take the guardrail 18 and the side panel 20 out of the storage box 4, and then insert the plug-in rod 28 into the socket 17 to fix the guardrail 18 on the lifting platform 15, and then insert the clamping block 29 into the clamping groove 19, so that the side panel 20 can be fixed between the two guardrails 18, so that the staff is blocked by the guardrail 18 and the side panel 20 to prevent the staff from falling, and then continue to raise the height of the lifting platform 15 to facilitate the staff to repair the power equipment, and after the work is completed, the staff can store the guardrail 18 and the side panel 20 in the storage box 4, and after lowering the height, the lifting platform 15 can be collected in the storage seat 1 for the staff to carry and transport.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0028] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
