Abstract
Description
Technical Field
[0001] This utility model relates to the field of toolbox technology, specifically a toolbox for power maintenance. Background Technology
[0002] In the daily maintenance and repair work of power systems, maintenance ladders and power maintenance toolboxes are essential equipment for working at heights. Maintenance personnel need to carry various tools with them to the work site. Currently, the common practice is to hang the toolbox directly on the crossbar or frame of the maintenance ladder, or have the workers carry it on their backs.
[0003] However, both methods have the following problems: First, directly suspended toolboxes are unstable and are prone to swaying or even falling off when workers move or encounter wind, posing a safety hazard of falling objects from heights; their position and angle are fixed and cannot be adjusted according to the real-time position and posture of workers, making it inconvenient to retrieve tools.
[0004] Secondly, carrying a toolbox increases the workload of workers, leading to faster physical exertion, and also prevents flexible adjustment of the toolbox angle to achieve the optimal retrieval position. Therefore, in view of the shortcomings of the existing technology, this utility model provides a toolbox for power maintenance to solve the above problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a power maintenance toolbox. By using a limiting seat and a rotatably connected clamp on the side of the toolbox body, combined with a clamping mechanism within the clamp and an angle positioning mechanism acting on the clamp's rotating shaft, the toolbox body can be securely locked onto the maintenance ladder frame via the clamping mechanism. This effectively prevents the toolbox from shaking or falling during operation, improving safety during high-altitude work. Simultaneously, the angle positioning mechanism can adjust and reliably lock the rotation angle of the clamp, allowing the toolbox body to be adjusted to the optimal angle for easy tool access according to the operator's actual needs, thus meeting the usage requirements of power maintenance toolboxes on high-altitude maintenance ladders.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a toolbox for power maintenance, comprising a toolbox body disposed on the side of a maintenance ladder frame, a lid on the top of the toolbox body, an inner cavity for placing power maintenance tools, a limiting seat on the side of the toolbox body, and a clamping seat rotatably connected to the side of the limiting seat; The clamping seat is equipped with a clamping mechanism inside, and a positioning wheel is provided on the rotating shaft of the clamping seat; The limiting seat is equipped with an angle positioning mechanism for limiting the position of the positioning wheel.
[0007] Preferably, the clamping mechanism includes: The first screw is threaded onto the clamp. The clamping block is rotatably connected to the end of the first screw and slidably connected to the surface of the clamping seat.
[0008] Preferably, a rubber block is provided on the side of the clamping block away from the first screw.
[0009] Preferably, the tilt positioning mechanism includes: The second screw is threaded onto the limiting seat; The extrusion block is slidably connected inside the limiting seat and rotatably connected to the end of the second screw.
[0010] Preferably, the extrusion block is provided with a rubber pad on the side near the positioning wheel.
[0011] Preferably, the first screw is provided with a first handle.
[0012] Preferably, the second screw is provided with a second handle.
[0013] The technical effects and advantages of this utility model are as follows: This power maintenance toolbox, through a limiting seat and a rotatably connected clamp on the side of the toolbox body, combined with a clamping mechanism within the clamp and an angle positioning mechanism acting on the clamp's rotating shaft, allows the toolbox body to be securely locked onto the maintenance ladder frame via the clamping mechanism. This effectively prevents the toolbox from shaking or falling during operation, improving the safety of high-altitude operations. At the same time, the angle positioning mechanism can adjust and reliably lock the rotation angle of the clamp, allowing the toolbox body to be adjusted to the optimal angle for easy tool access according to the actual needs of the operators, thus meeting the usage requirements of power maintenance toolboxes on high-altitude maintenance ladders.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] This embodiment discloses a toolbox for power maintenance, according to the appendix. Figure 1 To be continued Figure 5 As shown, the toolbox body 10 is provided on the side of the maintenance ladder frame 60. The top of the toolbox body 10 is provided with a box cover 11. The inner cavity of the toolbox body 10 is used to place electrical maintenance tools. The side of the toolbox body 10 is provided with a limiting seat 20. The side of the limiting seat 20 is rotatably connected to a clamping seat 30. The clamping seat 30 is provided with a clamping mechanism 40 inside. The clamping seat 30 is provided with a positioning wheel 31 on its rotating shaft. The limiting seat 20 is provided with an angle positioning mechanism 50 for limiting the position of the positioning wheel 31 inside.
[0019] According to the appendix Figure 2 As shown, the clamping mechanism 40 includes a first screw 41 and a clamping block 42. The first screw 41 is threadedly connected to the clamping seat 30, and the clamping block 42 is rotatably connected to the end of the first screw 41 and slidably connected to the surface of the clamping seat 30. By rotating the first screw 41, the clamping block 42 can be driven to move linearly, thereby achieving clamping or releasing operations. Furthermore, a rubber block 43 is provided on the side of the clamping block 42 away from the first screw 41 to increase friction and prevent damage to the maintenance ladder frame 60.
[0020] According to the appendix Figure 3 and attached Figure 5As shown, the tilt positioning mechanism 50 includes a second screw 51 and a pressing block 52. The second screw 51 is threadedly connected to the limiting seat 20, and the pressing block 52 is slidably connected inside the limiting seat 20 and rotatably connected to the end of the second screw 51. By rotating the second screw 51, the pressing block 52 can be pushed to move, thereby pressing or releasing the positioning wheel 31. Furthermore, a rubber pad 53 is provided on the side of the pressing block 52 near the positioning wheel 31 to increase friction and prevent wear on the positioning wheel 31.
[0021] According to the appendix Figure 4 As shown, the positioning wheel 31 is fixed on the rotating shaft of the clamp 30 and rotates with the clamp 30. Its outer circumferential surface contacts the extrusion block 52, and the angle is fixed by the clamping force of the tilt positioning mechanism 50.
[0022] According to the appendix Figure 1 To be continued Figure 5 As shown, the first screw 41 is provided with a first handle, which facilitates manual rotation of the first screw 41 to adjust the clamping force; the second screw 51 is provided with a second handle, which facilitates manual rotation of the second screw 51 to adjust the tilt angle lock.
[0023] According to the appendix Figure 1 To be continued Figure 5 As shown, it is particularly important to emphasize that the clamping mechanism 40, through the cooperation of the first screw 41 and the clamping block 42, can adapt to the maintenance ladder frame 60 of different sizes, and the rubber block 43 provides soft contact to protect the surface of the frame; the tilt positioning mechanism 50, through the cooperation of the second screw 51 and the pressing block 52, can continuously lock the positioning wheel 31, realize the stepless adjustment of the clamping seat 30 at multiple angles, and ensure the stable placement of the toolbox body 10.
[0024] According to the appendix Figure 1 To be continued Figure 5 As shown, it is particularly important to note that the limiting seat 20 has a sliding groove inside, which is used to guide the linear movement of the extrusion block 52 and prevent rotation; the rotating connection between the clamp 30 and the limiting seat 20 is provided with a bearing to ensure smooth rotation.
[0025] Example 1: This example uses the fixed toolbox to the maintenance ladder frame 60 as an example, combined with the attached... Figure 1 To be continued Figure 5 Detailed workflow description: The workflow is as follows: Place the clamp 30 in a suitable position on the maintenance ladder frame 60, rotate the first handle on the first screw 41 to drive the clamp 42 to move toward the frame, and clamp the frame by the rubber block 43.
[0026] Adjust the toolbox body 10 to the desired angle, rotate the second handle on the second screw 51, push the extrusion block 52 to press the positioning wheel 31, and lock the angle using the friction of the rubber pad 53.
[0027] Open the box cover 11 to take out tools for maintenance work, and close the box cover 11 after use.
[0028] After the maintenance is completed, loosen the second screw 51 and the first screw 41, and remove the toolbox.
[0029] Example 2: This example uses adjusting the toolbox angle as an example, combined with the attached... Figure 1 To be continued Figure 5 Detailed workflow description: The workflow is as follows: When it is necessary to change the angle of the toolbox during maintenance, first rotate the second handle on the second screw 51 to disengage the pressing block 52 from the positioning wheel 31 and release the angle lock.
[0030] Manually rotate the clamp 30 to a new angle to position the toolbox body 10 in the optimal access position.
[0031] Rotate the second handle on the second screw 51 to make the pressing block 52 press the positioning wheel 31 again and fix the new angle.
[0032] If the dimensions of the maintenance ladder frame 60 change, the clamping mechanism 40 can be adjusted simultaneously and the first screw 41 can be rotated to re-clamp.
[0033] In summary, this power maintenance toolbox, through the limiting seat 20 located on the side of the toolbox body 10 and the rotatably connected clamp 30, combined with the clamping mechanism 40 within the clamp 30 and the tilt positioning mechanism 50 acting on the rotation axis of the clamp 30, allows the toolbox body 10 to be firmly locked onto the maintenance ladder frame 60 by the clamping mechanism 40. This effectively prevents the toolbox body 10 from shaking or falling during operation, improving the safety of high-altitude operations. At the same time, the tilt positioning mechanism 50 can adjust and reliably lock the rotation angle of the clamp 30, allowing the toolbox body 10 to be adjusted to the optimal angle for easy tool access according to the actual needs of the operators, thereby meeting the usage requirements of power maintenance toolboxes on high-altitude maintenance ladders.
