Description

[Detailed explanation of the idea] The present invention relates to an improvement of a mobile trolley.

Generally, the mounting platform of a mobile cart such as a traverser or lifter on which drawer-type electrical equipment stored in a switchboard is placed has a guide to guide the drawer-type electrical equipment installed on the floor of the switchboard. A pair of guide rails with the same width as the rails are installed so that draw-out electrical equipment can easily enter and exit the switchboard.

The width of this guide rail varies depending on the type, capacity, etc. of the drawer-type electrical device.

Normally, switchboards are often installed as multi-sided panels,
Various drawer-type electrical devices are housed inside the panel.

In such cases, conventionally, separate movable carts were prepared for each type of drawer-type electrical equipment, or a movable cart provided with a pair of variable arms on which guide rails were installed.

However, in the former case, it is necessary to prepare a number of movable carts depending on the type of guide rail pitch, and the preparation costs are high.In the latter case, one movable cart can be used, but the The drawback is that the arm adjustment machine is complicated and expensive.

One device of the present invention can be used in many types of drawer-type electrical equipment.

To provide a mobile cart with a simple structure and low cost.

An embodiment of the present invention will be explained with reference to the drawings in the case of a lifter underground.

Reference numeral 1 denotes a mobile trolley used as a lifter, which includes a mounting table 4 on which drawer-type electrical equipment 3 stored in a switchboard 2 is placed when people come out, a frame 5 vertically connected to the mounting table 4, and a frame. A column 6 that slidably holds the column 5, a base 7 that supports the column 6, wheels 8 for transportation installed at the bottom of the base 7, and a lifting device that connects the platform 4 with a rope 9 and raises and lowers it. 10. Operates the elevating device 10...consists of a handle 11, etc.

A large number of fitting holes 12 are bored in the mounting table 4, and by fitting a plurality of fitting pins 14 protruding from a pair of guide rails 13 into predetermined fitting holes 12, a drawer-type electric device can be mounted. A pair of guide rails 13 are set at positions corresponding to 3.

The movable trolley configured in this way can be used with other drawer-type electrical equipment 3.
If applicable to a, the guide rail 13 set on the mounting table 4 may be reset to a position corresponding to the drawer-type electric device 3a.

Similarly, when the present invention is applied to electric appliances 3b, 3c, etc. (not shown), the guide rails 13 may be reset to corresponding positions.

In other words, guide rails 1 are installed depending on the type of drawer-type electrical equipment that is housed in several switchboards arranged in one electrical facility.
If the fitting hole 12 of the mounting table 4 is fitted in such a manner that 3 can be set, it is only necessary to prepare one movable cart 1.

It should be noted that if the setting positions of the guide rails 13 corresponding to each of the electric devices 3, 3a, 3b, 3o, etc. are clearly indicated on the mounting table 4 as shown in FIG. This is convenient when changing the settings of the guide rail 13.

According to the present invention, as many fitting holes as necessary are drilled in the mounting table and a single row of guide rails with protruding fitting pins are used, so that a single unit can handle a large number of fitting holes. Applicable to various types of drawer-type electrical equipment.

A mobile cart with a simple structure and low cost can be obtained.
