Description

Metal armored switch special maintenance transfer vehicle

technical field

The utility model relates to an auxiliary device for a 10KV metal armored switch, in particular to a special maintenance transfer vehicle for a metal armored switch.

Background technique

At present, most substations in my country generally install 10KV metal armored removable switchgear. The handcarts in this metal armored switchgear need to be carried by specially configured transfer vehicles for assembly and maintenance of the switchgear. Chinese Utility Model Patent Publication Document CN202508128U discloses a metal armored removable switchgear special circuit breaker transfer trolley, this transfer trolley is mainly connected between the vehicle floor and the roof frame by the vehicle floor, the roof frame and the support. Composed of four columns, rollers are installed under the vehicle floor. In order to save materials and reduce costs, this kind of transfer trolley has low space utilization in its on-site application, because there is not enough space on the car body to place maintenance tools, so that the staff have to use the tools used for maintenance during maintenance operations. All kinds of tools are carried with you, but the tools that everyone carries are limited. In many cases, the shaker and some maintenance accessories that need to be used in the maintenance process need to be used repeatedly by the staff, which is very inconvenient to use and increases the work. Labor intensity of personnel.

Detailed ways

The specific embodiment of the utility model is described in detail below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, the car body of the metal armored switch special maintenance transfer vehicle of the present invention includes a rectangular frame surrounded by the top plate 1, the bottom plate 2 and the left and right side plates 3, and the top plate 1 is located in the rectangular frame. There are two layers of storage pallets 6 at the upper and lower intervals between the base plate 2, and each storage pallet 6 is guided and slidably installed on the left and right side plates 3 through the two-way slide rails 12 provided on the left and right sides that can be pulled back and forth. inside. Folding workbenches are respectively installed on the left and right outer sides of the top of the rectangular frame. The foldable workbenches include hinged left and right worktables, and the axis of the hinge shaft between the left and right workbenches and the rectangular frame extends forward and backward. Therefore, the left and right worktables respectively have a working position in a horizontal state after being opened and a folding position vertically pasted outside the left and right side panels 3 after being folded. Folding support plates distributed at intervals for supporting and fixing the left and right workbenches at the working position, each folded support plate is rotatably assembled on the corresponding left and right side plates 3 through the hinge shaft extending vertically from the rotation axis. In this embodiment, the specific structure of the folding workbench is described by taking the folding workbench arranged on the right side as an example. The platen 7 is rotatably assembled on the outer plate surface of the right side plate 3 through two horizontal hinges 10 arranged at intervals in the front and back of the bottom edge. 7. The two horizontal hinges 10 can be turned up and down. On the right side panel 3 below the right worktable 7, two vertical hinges 11 arranged at vertical intervals are installed with two folding support plates 8 at intervals. , the two folded support plates 8 are right-angled triangle structures, and the two right-angled sides of the two folded support plates 8 are respectively attached to the bottom surface of the right table plate 7 and the right side plate 3 when they are in a supporting state. When it is necessary to overhaul the equipment, turn the right workbench 7 up to the horizontal working position, and turn the two folded support plates 8 to the support position vertical to the right side plate 3 and the right workbench 7 through the vertical hinge 11 , the right worktable 7 is fixed in the working position through the two folded support plates 8 arranged at intervals before and after and provides stable support for the right workbench 7. 8 Turn to the position where it fits the outer surface of the right side plate 3, so that it is separated from the support of the right workbench 7, and at the same time, turn the right workbench 7 downwards through the horizontal hinge 10 so that it is in contact with the right side plate 3 fit together to complete the folding of the folding workbench. In order to facilitate the operation of the staff during the maintenance process, in this embodiment, the above-mentioned left and right worktables are flush with the top plate 1 when they are in the horizontal working position. In addition, the outer edges of the left and right worktables adopt arc-shaped structures, so that the overhaul transfer trolley forms an oblong structure during the overhaul process, thereby avoiding injuries to the nearby staff during the overhaul operation and improving Safety of maintenance work.

In addition, in order to avoid the displacement of the maintenance transfer trolley during the maintenance operation and endanger the safety of the equipment, in this embodiment, universal wheels with brake mechanisms are respectively installed on the four corners of the bottom plate 2, which can be used as the hand of the metal armored switch cabinet. After the car moves to the maintenance transfer trolley, the position of the trolley can be fixed by using the brake mechanism of the universal wheel, and the brake mechanism is released after the maintenance is completed to facilitate the movement of the trolley. This universal wheel with a brake mechanism is a prior art and will not be described in detail here.

In order to facilitate the matching of the maintenance transfer trolley with different types of switch cabinets, in this embodiment, it is also equipped with a handcart receiving plate 5 on the top plate 1 through adjustable feet 4 . The height and level of the handcart receiving plate 5 can be fine-tuned by the adjustable legs 4, which is convenient for connecting with handcarts of different heights.

To facilitate the movement of the maintenance transfer trolley, handles 13 are respectively fixed on the front and rear sides of the rectangular frame top of the car body.
