As shown in FIGS. 2 and 3, the elctic storage for a pump car according to the embodiment of the present invention comprises a main body 110 and a reinforcing plate 120.

The main body 110 is arc-shaped and bent at about 90 degrees, and has hollows at both ends thereof.

The main body 110 is made of a high-manganese (Hi-Mn) material. The high manganese is an alloy containing manganese and is widely used for storing el concrete for conveying because of its strong abrasion resistance.

In addition, a flange 111 protrudes from the outer circumferential surfaces of both ends of the body 110, and the diameter and the size of the flange 111 may be variously changed according to the use.

In addition, the main body 110 is a cast body integrally manufactured through a mold.

As shown in FIG. 3, the main body 110 is connected to a conveying pipe of a pump car, and the material such as concrete moving in the arrow direction through the conveying pipe continuously impacts on the center portion, .

The reinforcing plate 120 is mounted at the center of the inner circumferential surface of the main body 110 to prevent damage due to the impact.

The reinforcing plate 120 is made of manganese (Mn), is a casting manufactured through a mold, and has a constant thickness.

The reinforcing plate 120 is formed to have a generally half-round shape as viewed from the longitudinal section, and has both ends formed to be disposed near both ends of the main body 110, and is in surface contact with the inner peripheral surface of the main body 110.

The reinforcing plate 120 is welded to the inner circumferential surface of the main body 110 with a rim.

3, the rim of the reinforcing plate 120 and the welded portion between the rim of the main body 110 and the main body 110 are formed to have a gentle inclination so that when the concrete is moved into the main body 110, It is possible to prevent an impact from being applied to the rim portion of the plate 120 and to smooth the flow of the concrete.

In addition, the reinforcing plate 120 is formed with a reinforcing portion 121 in which metal material is melted at a high temperature and is directly bonded to a predetermined thickness.

The reinforcing portion 121 is formed by welding a metal material to a surface of the reinforcing plate 120 at a high temperature and then directly bonding the metal material to a predetermined thickness.

Here, the metal material is a wire made of manganese (Mn), and is melted by a CO2 welding method using a CO2 welding machine.

CO2 welding is a welding method in which a mixed gas of CO2 and O2 is used as a protective gas, which is excellent in weldability and excellent in antioxidant performance.

The reinforcing portion 121 has a predetermined thickness and is formed into a curved plate shape along the inner circumferential surface of the reinforcing plate 120.

The reinforcing portion 121 is once hardened after the manganese is once melted by the high heat, and the strength is greatly increased compared to the general net mans plates.

As described above, since the reinforcing plate 121 is formed by melting the metal material at a high temperature on the surface of the reinforcing plate 120 to have a predetermined thickness, the strength of the body 110 is increased, The life span can be prolonged and the ability to resist impact with the conveyed concrete material is improved.

In some cases, the reinforcing portion 121 may have a concavo-convex shape in which a plurality of protrusions 121a are spaced apart from each other in the direction of both ends of the body 110.

4 and 5, the reinforcing portion 121 is formed in a shape in which the protrusions 121a, which are elongated in the longitudinal direction of the arcs, are spaced apart from each other by a predetermined distance in the direction of both ends of the main body 110 do.

Also, the reinforcing portion 121 is formed such that a rim portion thereof is gently inclined to the surface of the main body 110 like the reinforcing plate 120.

The reinforcing portion 121 disperses an impact when the concrete material moves into the main body 110, thereby minimizing the damage to the main body 110.

In some cases, the reinforcing plate 120 may be detachably mounted to the main body 110.

6 and 7, the inner circumferential surface of the main body 110 is provided with a bolt portion 115 having a thread on the outer circumferential surface thereof.

6 is a partially cutaway view showing the inside of the main body 110. As shown in FIG.

The bolt portion 115 protrudes in a substantially cylindrical shape, and a thread is formed on the outer circumferential surface to be fastened to the nut 130.

In addition, the bolt portion 115 is formed of two pieces, and is spaced apart from both ends of the main body 110. Of course, the number and position of the bolt part 115 may be variously changed depending on circumstances.

The reinforcing plate 120 is inserted into the bolt part 115. The reinforcing plate 120 is formed with a coupling hole 125 into which the bolt part 115 is inserted.

The engaging holes 125 are formed in the thickness direction of the reinforcing plate 120 and spaced apart from the reinforcing plate 120 in the vicinity of both ends of the reinforcing plate 120 to correspond to the bolts 115.

The bolt 115 is inserted into the coupling hole 125 and the nut 130 is fastened to the bolt 115 in a state where the bolt 115 is inserted into the coupling hole 125 And the reinforcing plate 120 is detachably coupled to the main body 110.

Since the reinforcing plate 120 is detachably coupled to the bolt portion 115 with the nut 130, the reinforcing plate 120 can be easily replaced when the reinforcing plate 120 is broken, This results in a semi-permanent use without the need to replace the entire El storage.

The pump storage for the pump of the present invention having the above configuration is much higher in strength than the products having different strengths by the reinforcing portion 121 which is heated and melted by the CO2 welding machine and directly bonded to the surface of the reinforcing plate 120, The lifetime of the EL storage device can be prolonged and the ability to resist a collision with a material such as concrete moving into the main body 110 can be improved.

The present invention is not limited to the above-described embodiment, but can be variously modified within the scope of the technical idea of the present invention.
