Description

Forklift charger box

The present invention relates to a forklift charger box in which a transformer-type charger is mounted for charging a forklift, and more particularly, to a forklift charger box having a prefabricated structure while providing convenience of use.

In general, forklifts are classified into forklifts that operate with an internal combustion engine and electric forklifts that are equipped with batteries and operate electrically. do.

For electric forklifts, a separate charging area with a charger must be secured. If the built-in battery is exhausted and charging is required, move the forklift to the place where the charger is installed, open the battery cover, and connect the cable formed in the charger to the forklift battery. Dock to the terminal to charge the battery.

The method of installing the charger in the charging area is to install it on a wall or shelf. In order to secure an active space in the charging area, the charger is mainly installed by attaching it to the wall.

In particular, the transformer-type charger is very heavy and bulky, so a separate equipment cost for installing the charger is excessively high. Due to the nature of manufacturing, it is manufactured by welding, so the manufacturing cost is too high, the productivity is low, and it is difficult to transport and install because the volume is too large.

In addition, the usage pattern of electric forklifts is very high risk of fire because workers in industrial sites often leave their used forklifts charged during the day, and then go to work the next day and use the charged forklifts. An automatic diffusion fire extinguishing system is installed in the charging area to prevent fire.

The automatic diffusion fire extinguishing system is mainly installed on the ceiling of the charging area. Since forklifts are mainly used in industrial sites, industrial sites often have high floor heights like factory buildings, so there is a problem that the fire extinguishing effect by the fire extinguishing system is lowered. However, in order to install the fire extinguisher near the charger, there is a problem in that the installation cost is excessively high because facilities such as a separate shelf or bracket must be installed in advance.

In particular, as long as the fire extinguishing device is installed in the building, it is impossible to move it, and if you want to change the charging place, there is inconvenience and inconvenience of having to re-install it.

In addition, if you have several or more than tens of forklifts, you need to install as many chargers as the number of forklifts. There is a difficulty in securing a large installation space.

In addition, the electric wire used in the charger may be damaged by external forces such as being dented or pressed by heavy objects due to the nature of having an exposed structure. Because it is high, there is a need to safely store the wires.

The present invention is to solve the above problems, it is possible to manufacture with a simple assembly structure, and modularize the state in which the charger and the fire extinguisher are integrally mounted, so that the ease of assembling and the installation can be varied. .

The present invention as a technical idea to achieve the above object is a forklift charger box in which a transformer-type charger for charging an electric forklift is accommodated, and the front is opened so that the charger can be accommodated. The lower plate and the side plate, The side plate and the top plate can be easily and sequentially assembled.

In addition, in a state where the charger is accommodated in the case body, an internal space is secured on the upper side, and a fire extinguishing device is mounted on the upper plate to provide a fire extinguishing function in an individual charger box without providing a separate space for installing the fire extinguishing device. did it

In addition, the upper and lower plates of the case body are formed in the same structure to enable lamination assembly using the upper plate or lower plate without structural change, and even though the case body has a stacked structure, fire extinguishing devices can be individually installed in each charging box did it

According to the forklift charging case of the present invention, it is possible to significantly improve workability and reduce manufacturing costs by standardization and simple assembly structure of assembly parts cut and bent by iron plates, and mass production is possible, and packaging of assembly parts is possible. Logistics costs are reduced because the volume is reduced and on-site installation is possible, and the distribution structure can be greatly improved because assembly and installation can be easily performed on site even by non-professionals.

In addition, since a fire extinguishing device is installed in each charging box, although it is an individual fire extinguishing method, the fire extinguisher works immediately in the inner space. Even if an external force such as pulling the cable is applied while the charger is installed, the charger is prevented from being detached and can be used stably.

In addition, since options can be diversified with various additional parts, it is possible to provide products with quality and price suitable for the needs of consumers. can be used efficiently.

In addition, it is possible to reduce the maintenance cost because it prevents damage to the electric wire and makes repairs simple by replacing only the assembly parts even if the charger box is damaged by an external force such as a collision by a forklift. Even in this case, there is no need for cumbersome procedures such as removing and re-installing the fire extinguisher, and it is possible to move and install the charging place simply by moving only the charging box.

While the charger (C) is accommodated, a fire extinguishing device (Automatic Diffusion Extinguisher) is built-in to prevent fire in the individual charger box as shown in FIG. 5 .

The case body 100 is made of a metal plate, and the side plate 120 is configured in a state in which the front is opened, but the space is configured so that the transformer type charger (C) can be accommodated, and the upper and lower ends of the side plate. It may be configured to include an upper plate 140 and a lower plate 160 coupled to finish.

The case body 100 has an open front so that the charger C can be mounted or taken out in the case body, and the charger C can be operated. , The lower plates 140 and 160 are disposed, and the edges of the upper and lower plates 140 and 160 may be assembled to the side plate 120 and finished.

As a structure for assembling the side plate 120 and the upper and lower plates 140 and 160 , the upper and lower flanges 124 and 126 are bent to overlap the edges of the upper and lower plates 140 and 160 at the upper and lower ends of the side plate 120 , respectively. can be formed, and the edges of the upper and lower flanges 124 and 126 and the upper and lower plates 140 and 160 form fastening holes 122, 142 and 162 that are fixed by at least one screw coupling method, thereby simple assembly using bolts (B). This becomes possible.

That is, the lower flange 126 of the side plate 120 is brought into contact with the upper end of the lower plate 160 and the fastener B is first assembled in the fastening holes 122 and 162, and then the upper plate is placed on the upper flange 124 of the side plate again. It is configured to assemble the fastener (B) to the fastening holes 122 and 142 by raising the 140, so that the case body 100 can be simply assembled by sequential assembling of the metal plate.

At this time, if the tabs of the spiral structure are formed in the fastening holes 122 , 142 , and 162 , assembly is performed simply by fixing the bolts without the need for a separate nut.

In addition, the side plate 120 is made of a 'C' shape in cross section of the side plate 120 so that the case body 100 has a structure in which the front is opened. Rather than consist of three separate side plates on each side, the divided structure forms one side in a straight line and the other side in a 'L' shape to facilitate bending and stand up by itself. If the straight side plate is assembled after assembling first, the side plate 120 having a structure in which the front is opened on the upper part of the lower plate 160 can be easily assembled in an upright state.

When the side plate 120 is configured separately in this way, another fastening hole can be formed by forming a bent part at the seam, and it is firmly fixed by fastening using the fastener (B).

In addition, the side plate 120 has a through hole 102 formed in the rear of the case body 100 so that an electric wire for power supply can be connected to the outside, and the through hole 102 also has a packing for protecting the covering of the electric wire. can be fitted.

At this time, the through hole 102 is formed in both the upper and lower portions of the case body 100 so that the electric wire can be selectively drawn out to the upper or lower side, and the electric wire can be drawn out in various ways depending on the conditions of the installation space. Of course, by forming a hole at the top, even if the charger generates heat, it prevents the temperature inside the charger box from rising, and by allowing the heat to escape efficiently, it can prevent fire caused by overheating and reduce charging loss due to deterioration. have.

In addition, the lower portion of the case body 100 may be provided with a leg rest 104 for maintaining the case body 100 in a floating state from the ground, and the leg rest is at the lower end of the fastening shaft while the fastening shaft has a bolt structure. A support part is formed and seated on the ground, and the upper end of the fastening shaft is assembled with the case body 100 and a double nut structure to adjust the height.

And the case body 100 has a free space formed at the upper end of the space in which the charger (C) is accommodated, so that the fire extinguishing device (A) can be easily mounted through the fastening part 144 formed on the upper plate 140, of course, Fire prevention can be achieved by detecting a fire at a close distance from the charger (C), and even if a fire occurs in the charger (C), the fire is extinguished inside the case body 100, so fire suppression can be done safely in a very short time. can be done

And the side plate 120 has a bent portion 128 formed at the front end, and bent portions 148 and 168 are formed on the upper plate 140 and the lower plate 160, respectively, and the packing ( 180) can be mounted, and the packing 180 can be easily assembled by inserting it through the bent parts as a single packing, and the corners are not exposed and the assembled state is more robust while the corners of the metal plate are not exposed. Therefore, it is possible to prevent damage to the sheath of the electric wire and use it safely.

At this time, the bent portions 148 and 168 formed on the upper and lower plates 140 and 160 may be formed by bending a portion of the upper and lower plates, but more preferably bent bars 148a and 168a that are separated from the upper and lower plates 140 and 160 . It can be installed to further improve durability due to torsion while being reinforced by load.

On the other hand, the case body 100 is formed such that the fastening holes 122 and 142 of the upper plate 140 and the lower plate 160 correspond to the same position as shown in FIGS. 6 and 7 , and the lower plate 160 is also extinguished. If a fastening part (not shown) is formed so that the device A can be mounted, it is possible to switch between the upper plate and the lower plate, so that the assembly parts can be unified, thereby reducing the manufacturing cost.

That is, when assembling the upper plate (the upper and lower plates may not be distinguished when the upper and lower plates are manufactured identically) on the upper side of the side plate 120 of the case body 100, another side plate 120 is placed on the upper part of the upper plate. By attaching and assembling at the same time using the fastener (B), it is possible to assemble in multiple layers, and even though the structure is assembled in multiple layers, the case body 100 of the upper and lower layers is connected to each other by the tightening of the fasteners. A simple lamination assembly becomes possible.

At this time, the case body 100 is connected by one plate (upper plate or lower plate) between the stacked plates. Even if configured, it is possible to provide an individual fire extinguishing function for each charger by installing a fire extinguishing device (A) on each side.

On the other hand, a hook 200 may be provided on the upper end of the case body 100 so that an electric wire can be hung and fixed. , a fastening surface 240 of a bent structure to prevent flow in the fastening state is formed and can be fixed in close contact with the upper plate 140 using the fastener (B).
