Description

Special folding trolley suitable for relay protection maintenance work

Technical field:

The invention relates to a special folding trolley suitable for relay protection maintenance work.

Background technique:

In the prior art, there is no special place for test equipment and maintenance tools. After being unloaded from the engineering vehicle, they are randomly stacked and moved at the work site without taking into account the protection of special items. Therefore, for these test equipment, maintenance tools There are hidden dangers such as damage and loss of tools. At the same time, because the different switch cabinets that need to be tested are distributed in different positions in the protection room, the test equipment and maintenance tools are short in wiring, heavy in weight, and inconvenient to move. Scattered placement also causes inconvenient movement of equipment and tools, wastes manpower and increases working hours.

Relay protection testing work is a kind of electrical work that requires high standard operation. Irregular placement will easily reduce the safety awareness of the staff, thereby increasing the probability of safety accidents. Therefore, the use of testing equipment and maintenance tools more safely, rationally and efficiently has been mentioned as an urgent need for improvement and attention.

Invention content:

In order to overcome the defects of the prior art, the purpose of the present invention is to provide a special folding trolley suitable for relay protection maintenance work, which is a kind of relay protection testing equipment and maintenance tools, which is convenient to move overall, rich in functions and can be Folding trolley.

The present invention solves technical problem and adopts following technical scheme:

A special folding trolley suitable for relay protection maintenance work, including:

The car floor and the lockable universal wheels arranged on the bottom surface of the car floor;

A column bracket that is detachably connected to the vehicle floor, and a folding shelf is detachably connected to the top of the column bracket;

A foldable handle is arranged at one end of the car body of the trolley, and a cable reel socket and a cable reel take-up box are arranged on the foldable handle.

The folding shelf has a rectangular outer frame, and an insulating rod placing frame is provided outside the long side of the rectangular outer frame, and the insulating rod placing frame is elongated and has a semicircular cross section.

The vehicle floor is divided into a large current generator placement area, a toolbox placement area, a wiring placement area and a debris placement area.

The folding shelf is provided with a plurality of rectangular frames, which are in turn a data box placement frame, a relay protection calibrator placement frame, a computer placement frame, a label inspection machine placement frame and a calibrator wire rod placement frame.

Compared with the prior art, the beneficial effects of the present invention are reflected in:

Both the column support and the shelf can be disassembled from the vehicle floor, which is convenient for the staff to carry with the engineering vehicle. The test equipment and maintenance tools can be placed in the fixed position of the trolley, which can protect the special items and is not easy to lose. When operating at different positions on the job site, the overall movement of the trolley is convenient, and the universal wheels can be locked and fixed when reaching the designated position.

detailed description:

Embodiment: In combination with Figures 1-4, the special folding trolley suitable for relay protection maintenance work in this embodiment includes:

The vehicle floor 1 and the lockable universal wheels 5 arranged on the bottom surface of the vehicle floor; the column support 4 connected with the vehicle floor in a detachable manner, and the top of the column support is detachably connected with a folding shelf 2; in practical applications, The column bracket, the vehicle floor and the folding shelf can be connected by plugging methods such as mortise and tenon.

A foldable handle 3 is provided at one end of the car body of the trolley. The cable reel socket 6 and the cable reel take-up box 7 are arranged on the foldable handle 3. The foldable handle 3 is a round rod, which can also be connected by plugging and unplugging. on the column bracket.

The folding shelf 2 has a rectangular outer frame, and an insulating rod placement frame 8 is arranged outside the long side of the rectangular outer frame. There are a plurality of rectangular frames, which are successively a data box placement frame 13, a relay protection calibrator placement frame 14, a computer placement frame 15, a ticket inspection machine placement frame 16, and a calibrator wire rod placement frame 17. The vehicle floor 1 is divided into a large current generator placement area 9 , a toolbox placement area 10 , a wiring placement area 11 and a debris placement area 12 .

When receiving and carrying, the foldable handle 3 and the column support 4 of the trolley can be removed and placed on the vehicle floor 1, and the folding shelf 2 can also be removed and placed on the vehicle floor.

At the work site, test instruments and tools can be placed in the corresponding partitions on the vehicle floor 1 and folding shelf 2, and the whole trolley can be moved when testing at different positions on the work site.
