Description

Indoor GIS equipment transfer trolley

technical field

The utility model relates to a construction tool for a substation installation project, in particular to an auxiliary tool for indoor GIS equipment transfer.

Background technique

GIS equipment (gas insulated closed combined electrical appliances) transfer trolley installation usually uses a truck crane for component transfer, but in indoor GIS equipment installation, it is often impossible to use a truck crane to place it directly at the installation location due to limited space, and it needs to be placed outdoors After the equipment is unloaded, it is transferred to the installation location by an indoor aerial crane. In the traditional construction method, when the equipment is unloaded and then transferred to the indoor aerial crane for lifting, due to the narrow space, it usually requires multiple repositioning of the truck crane to achieve it. The construction efficiency is low, the steps are complicated, and the safety risk is high. The use of GIS equipment to process the trolley can reduce the risk during the transfer process, and the operation is simple, saving machinery and labor costs.

It also has a track made of inner channel steel.

The front wheel is a universal load-bearing wheel, and the rear wheel is an axial load-bearing wheel.

The two transverse channel steels of the trolley base are provided with support frame adjustment mounting screw holes for adjusting the distance between the two support frames.

Compared with the prior art, the utility model has the following characteristics and advantages:

1. There is no need for the crane to move multiple times to cooperate with the equipment transfer. The crane only needs to unload the equipment outdoors, which reduces the cost of machinery and improves the efficiency of equipment transfer.

2. There is no need for a crane or jib to enter the room, reducing safety risks.

3. The base of the trolley is equipped with multiple load-bearing wheel fixing holes and support frame fixing holes, which can be adjusted according to the size and weight of the suspended equipment to meet the transfer needs of various equipment.

4. The track is used to control the moving direction of the trolley, and the friction between the trolley and the ground is reduced. It can be easily pushed and pulled in place with a small amount of manpower, reducing labor costs and greatly improving work efficiency.

5. The utility model has the characteristics of simple structure, low manufacturing cost, fast installation and removal, safety and reliability.

Detailed ways

Fig. 1, Fig. 2, Fig. 3 show, this indoor GIS equipment transfer trolley, trolley base 1 is welded between two transverse channel steels by a longitudinal channel steel; The rear part is provided with a pair of front wheels and a pair of rear wheels respectively; two transverse channel steels on the trolley base 1 are provided with two support frames 2 with the same structure, and the support frames 2 are welded by the same type of channel steel. The structure is: the same left and right vertical plates 2b are welded on the bottom plate 2a, the connecting plate 2c (set in the horizontal direction) is welded at the middle position between the two vertical plates 2b, and the right oblique plate 2e is welded at the middle of the connecting plate 2c And between the top of the right vertical plate 2b, the left and right inclined plates are symmetrically arranged left and right, and the upper surfaces of the left and right inclined plates are covered with a cushion layer 2f, and the middle part of the bottom surface of the connecting plate 2c and the bottom plate of the support frame (Welded horizontally on the two long channel steels of the trolley base) A vertical support plate 2d is welded between them; the above two support frames 2 are fixed to the trolley base 1 by bolts through the screw holes on the bottom plate 2a of the support frame 2 On the two transverse channel steel. The track is made of channel steel. The convex surface of the channel steel is placed on the ground, and the opening of the channel steel is upward. The front wheel is a universal load-bearing wheel 3, and the rear wheel is an axial load-bearing wheel 4.

Referring to Fig. 2, the two transverse channel steels on the base of the trolley are provided with support frame adjustment mounting screw holes 5 for adjusting the distance between the two support frames 2 (opening holes as required).

Example:

The GIS equipment transfer trolley is mainly assembled by base, track, support frame, support and fixing equipment, and large load-bearing rollers (see attached drawing 1 for details).

The trolley base (see attached drawing 2 and attached drawing 3) is composed of two long channel steels ([14 channel steels) and three fixed short channel steels. Vertical, and the connection method between each other is welding. Different positions on the long channel steel of the base are provided with screw holes for adjusting the mounting screw holes 5 and load wheel screw holes 6 for adjusting the positions of the two support frames and the load wheel positions. The track of the trolley is made of [10 channel steel, which is composed of multiple channel steel welded according to the actual length, and fixed by welding with threaded steel bars.
