Description

Technical Field

[0001] This utility model relates to a maintenance rack, and more particularly to an electrical maintenance insulation maintenance rack. Background Technology

[0002] In the operation and maintenance of power systems, insulated inspection racks are indispensable and crucial equipment. Their main function is to provide maintenance personnel with a safe and stable high-altitude working platform while ensuring sufficient insulation distance from live equipment. Traditional insulated inspection racks are typically made of insulating materials such as fiberglass or epoxy resin, which effectively prevents current conduction and protects the personal safety of maintenance personnel.

[0003] Since power maintenance work is often carried out at heights of several meters or even tens of meters, the overall center of gravity of the maintenance scaffold is raised accordingly. This makes the insulated maintenance scaffold highly susceptible to tipping over when encountering lateral winds or personnel movement, especially when working on uneven ground, where the stability of the scaffold is even more difficult to guarantee. In order to achieve stability, traditional maintenance scaffolds often adopt a design with an enlarged base, which makes the equipment bulky and inconvenient to move, thus affecting work efficiency. Utility Model Content

[0004] This utility model addresses the shortcomings of the prior art mentioned above by providing an electrical maintenance insulation inspection frame that can improve stability.

[0005] The technical solution is as follows: A power maintenance insulation inspection frame, comprising a movable base, a mounting base, a hydraulic base, and a support frame; further comprising: a hydraulic system fixedly connected to the mounting base, the hydraulic system being connected to the hydraulic base; a controller fixedly connected to the mounting base, the controller being connected to the hydraulic system; a bidirectional hydraulic rod disposed on the movable base, the hydraulic system being connected to the bidirectional hydraulic rod; mounting plates fixedly connected to the two control ends of the bidirectional hydraulic rod; a guide rod disposed between the mounting plate and the bidirectional hydraulic rod, the guide rod being fixedly connected to the mounting plate and slidably connected to the bidirectional hydraulic rod; hydraulic columns fixedly connected below the mounting plates, each mounting plate having two sets of hydraulic columns symmetrically distributed on both sides of the mounting plate, the hydraulic system being connected to the hydraulic columns; and footings disposed at the bottom of the control ends of the hydraulic columns.

[0006] Furthermore, the maintenance frame also includes: a motor fixedly connected to the movable base, a controller connected to the motor; a rotary table rotatably connected to the movable base, the output end of the motor being fixed to the rotary table, and a bidirectional hydraulic rod fixedly connected to the rotary table.

[0007] Furthermore, the maintenance frame also includes: ball bearings embedded in the rotary table, the ball bearings being disposed on the contact surface between the rotary table and the movable base.

[0008] Furthermore, the maintenance frame also includes: a rotating shaft fixedly connected to the bottom of the control end of the hydraulic column, with a foot rotatably connected to the rotating shaft; and a torsion spring fixedly connected between the foot and the rotating shaft.

[0009] Furthermore, the maintenance frame also includes a friction pad that is fixedly connected to the bottom surface of the base.

[0010] Furthermore, the inspection frame also includes a supplementary light fixedly connected to the mounting plate.

[0011] The beneficial effects are as follows: By increasing the number of support points and expanding the footprint of this utility model, the center of gravity height is lowered, improving the stability of its use. This utility model maintains the original transportation flexibility while improving support safety and stability, thus resolving the contradiction between transportation flexibility and support stability in existing technologies. Furthermore, by setting the angle of the footings, this utility model can automatically adjust according to ground undulations, allowing each footing to independently adapt to different slopes, ensuring optimal support in various complex terrain conditions, thereby improving the terrain adaptability of this maintenance frame.

Detailed Implementation

[0017] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Example: An insulated inspection rack for power maintenance, such as Figures 1-2As shown, it includes: a movable base 1, which enables the free displacement of this maintenance frame; a mounting base 2 fixedly installed on the movable base 1; a hydraulic base 3 fixedly installed on the mounting base 2; and a support frame 5 fixedly installed on the control end of the hydraulic base 3, which provides a working platform for workers.

[0019] like Figures 1-2 As shown, this maintenance frame also includes: a hydraulic system 4 fixedly installed on the mounting base 2, the hydraulic system 4 being connected to the hydraulic base 3 to control the up-and-down movement of the hydraulic base 3 and the support frame 5; a controller 6 fixedly installed on the mounting base 2, the controller 6 being connected to the hydraulic system 4 to control the operation of the hydraulic system 4; a bidirectional hydraulic rod 9 fixedly installed on the rotary table 8, the hydraulic system 4 being connected to the bidirectional hydraulic rod 9 to control the synchronous extension and retraction of the two control ends of the bidirectional hydraulic rod 9; mounting plates 10 fixedly installed on the two control ends of the bidirectional hydraulic rod 9 respectively; a guide rod 11 disposed between the mounting plate 10 and the bidirectional hydraulic rod 9, the guide rod 11 being fixedly installed with the mounting plate 10 and slidably installed with the bidirectional hydraulic rod 9; hydraulic columns 12 fixedly installed below the mounting plate 10, each mounting plate 10 being provided with two sets of hydraulic columns 12, the two sets of hydraulic columns 12 being symmetrically distributed on both sides of the mounting plate 10, the hydraulic system 4 being connected to the hydraulic columns 12 to control the up-and-down displacement of the control ends of the hydraulic columns 12, each hydraulic column 12 independently controlling its own control end; and feet 13 disposed at the bottom of the control ends of the hydraulic columns 12.

[0020] After moving the maintenance frame to the working position, the bidirectional hydraulic rod 9 is first activated to drive the two mounting plates 10 to move outward and unfold. Then, each hydraulic column 12 is activated to control the feet 13 to move down smoothly. After the feet 13 are in full contact with the ground, the hydraulic system 4 is shut off. Therefore, by increasing the support points and expanding the floor area of ​​the maintenance frame, the center of gravity of the maintenance frame is lowered, thus improving the stability of the maintenance frame. The maintenance frame can maintain the original transportation flexibility while improving the support safety and stability, thereby solving the contradiction between transportation flexibility and support stability in the existing technology.

[0021] like Figure 1 , Figure 2 and 4As shown, this maintenance rack also includes: a motor 7 fixedly installed in the movable base 1, a controller 6 connected to the motor 7 to control the operation of the motor 7; a rotary table 8 rotatably installed on the movable base 1, the output end of the motor 7 fixed to the rotary table 8 to control the free rotation of the rotary table 8, a bidirectional hydraulic rod 9 fixedly installed on the rotary table 8; an anti-collision pad 18 fixedly installed on the mounting base 2, the anti-collision pad 18 reducing the impact force caused by accidental installation of the mounting base 2 during the rotation of the rotary table 8, thereby improving the operational safety of this maintenance rack; and ball bearings 17 embedded in the rotary table 8, the ball bearings 17 being disposed on the contact surface between the rotary table 8 and the movable base 1, the ball bearings 17 being used to reduce the friction between the rotary table 8 and the movable base 1, and to improve the smoothness of the rotation of the rotary table 8.

[0022] After moving the maintenance frame to the working position and before controlling the foot 13 to contact the ground, start the motor 7 to drive the rotary table 8 to adjust the orientation of the foot 13, optimize the selection of the support point position, avoid areas with uneven ground or insufficient load-bearing capacity, until the optimal support point position is determined, and then control the foot 13 to contact the ground, thereby improving the support effect of the foot 13 and further improving the support stability of the maintenance frame.

[0023] like Figures 1-4 As shown, this maintenance frame also includes: a rotating shaft 14 fixedly installed at the bottom of the control end of the hydraulic column 12, and a foot 13 rotatably installed on the rotating shaft 14; a torsion spring 15 fixedly installed between the foot 13 and the rotating shaft 14, the torsion spring 15 being sleeved on the rotating shaft 14; and a friction pad 16 fixedly installed on the bottom surface of the foot 13, the friction pad 16 being used to increase the friction between the foot 13 and the ground, thereby enabling the foot 13 to provide stable support.

[0024] When the foot 13 contacts the ground under the drive of the hydraulic column 12, the foot 13 will be able to automatically rotate around the pivot 14 according to the undulation of the ground, and the torsion spring 15 will be twisted, so that each foot 13 can independently adapt to different slopes, ensuring that the maintenance frame can obtain the best support state under various complex terrain conditions, thereby improving the terrain adaptability of the maintenance frame; after the foot 13 is retracted upward, the torsion spring 15 automatically rotates the foot 13 back.

[0025] like Figures 1-4 As shown, this maintenance rack also includes: a supplementary light 19 fixedly installed on the mounting plate 10; the supplementary light 19 is used to provide a better visual environment, enabling workers to clearly identify the ground conditions, so as to help workers better determine the support position of the foot 13 and improve the use effect of this maintenance rack.

[0026] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
