Description

[Detailed Description of the Invention] This invention relates to a stopper device for a bogie for fixing a bogie placed on a rail.

For example, in a power supply device in which a rectifier and a storage battery are housed in a housing, the storage battery is placed on a trolley to facilitate loading and unloading of the storage battery into the housing, and the battery is placed on a rail installed inside the housing. is stored inside the casing.

Conventionally, in this type of power supply device, a cart is simply placed on a rail inside the housing, so the cart carrying the storage battery tends to move easily when moving the housing, resulting in various problems.

This invention was made in order to improve the above-mentioned drawbacks, and provides a stopper device for a cart that is configured so that a stopper for preventing movement of the cart can be easily attached to a rail installed in a housing. be.

Hereinafter, one embodiment of this invention will be described in detail based on the attached drawings.

FIG. 1 shows a casing 1 of a power supply device, with reference numeral 2 a front door, 3 a ceiling plate, and 4 a hanging bolt for hoisting the casing 1 when moving it.

At the bottom of the casing 1, there is a U-shaped cross-sectional rail 5 made of a steel plate with an interval corresponding to the width d of the moving wheels 6a attached to the trolley 6 on which a plurality of storage batteries 9 are mounted. They are installed in two horizontal parallels.

A wheel stopper 7 is fixed to the rear end of the rail 5 at a position where the rear wheels of the trolley 6 come into contact, and the front door 2 side has a wheel stopper 7 fixed to the rear end of the rail 5.
When the wheels 6a of the truck 6 are inserted into the U-shape of the rail 5 and the truck 6 is pushed into the housing 1, and the rear wheels contact the wheel chocks 7, the front wheels of the truck 6 will stop. Recessed portions 5a are cut out in both side walls of the rail 5.

FIG. 3 shows a U-shaped stopper 8 in which a protrusion 8b is formed by bending both ends of a flat plate member, and a concave notch 5 in a rail 5.
Half-tapered grooves 8a that fit into the grooves 8a are formed at intervals equal to the intervals between the side walls 5a of the rail 5.

The recessed groove 8a is formed on the lower surface of a U-shape in a single-tapered shape with only the inner edge sloping, thereby facilitating fitting of the rail 5 into the recessed portion 5a.

The protrusion 8b of the stopper 8 connects the stopper 8 to the rail 5.
When the stopper 8 is installed, the stopper 8 is disposed opposite to the outer surface of both side walls 5a of the rail 5 to prevent the stopper 8 from escaping and to increase the strength of the stopper 8.

The stopper 8 of the truck 6 is attached to and removed from the rail 5 formed as described above as shown in FIGS. 4 and 5.

That is, a wheel stopper 7 is fixed to a rail 5 installed in the housing 1, and a recess 5a into which a stopper 8 fits is formed, so a cart 6a on which a storage battery is mounted is inserted into the rail 5 and the housing 1 is moved. Push it inside and store it.

Therefore, the recess i8a of the stopper 8 may be fitted into the recess 5a of the rail 5 after the rear wheel of the truck 6 contacts the wheel stopper 7.

Therefore, the trolley 6 can be safely and reliably fixed within the rails of the housing 1.

As explained in detail above, according to this invention, the bogie can be safely and reliably fixed with a very simple structure, and the stopper can be easily attached to the recess of the rail, making it practical. It is very effective.
