Figure 5 is an exploded perspective view showing the horizontal correction means, Figure 5 is a longitudinal sectional view showing a state of use of the horizontal correction means shown in FIG.

As shown in the present invention, a pair of ridges 52 are formed along the long axis at the center of the upper surface, and a guide plate 54 for guiding the mobile rack 2 on the outer side of the ridges 52 is raised. A plate-shaped steel rail base 50 which protrudes integrally while being symmetric about 52 is included.

Here, the ridge 52 is preferably formed to have a cross-section with a rounded corner as shown in Figure 3, the guide plate 54 on both sides of the ridge 52 is configured to have an inward flange by bending the upper end It is desirable to.

Of course, the guide plate 54 is for guiding the rack wheels installed in the lower portion of the mobile rack, not shown, so as to form an inward flange as shown, it is possible to more fully guide both sides of the rack wheels.

And, the subject innovation is installed along the longitudinal direction of the ridge 52, as shown in Figure 3, the upper portion between the pair of ridge 52 formed in the rail base 50, the vertical through the top at equal intervals It has a plurality of bolt insertion holes 62, the lower outer peripheral surface includes a rail rod 60 is formed with a nut insertion groove 64 along the axial direction.

At this time, the bolt insertion hole 62 was formed by forming a tapered expansion groove on the top as shown in Figure 3 and 4, so that the head portion of the pin bolt 70 to be described later, the nut insertion groove 64 Was configured to have a width slightly larger than the diameter of the nut 80 so that the nut 80 to be described later is inserted and rotated.

In addition, the present invention, as shown in Figure 4, is inserted into the bolt insertion hole 62 of the rail rod 60, the pin bolt 70 and the rail rod 60 is formed with a male screw in the middle portion of the axial direction The nut 80 is inserted into the nut insertion groove 64 of the nut and screwed with the male screw of the pin bolt 70 to fix the pin bolt 70 to the rail rod 60.

Of course, the head portion of the pin bolt 70 is inserted into the upper end of the bolt insertion hole 62 as described above, and concealed to the inside of the rail rod 60 as shown in Figure 3, the male screw of the middle portion of the bolt The lower portion of the insertion hole 62, that is, protrudes into the nut insertion groove 64 and screwed with the nut 80.

In addition, the present invention includes a horizontal correction means for correcting the horizontal level of the rail rod 60 by raising and lowering the rail rod 60 with respect to the rail base 50.

Such a horizontal correction means is, for example, as shown in Figures 3 and 4, the longitudinal direction of the plurality of nut holes 56 vertically penetrated in the upper surface between the raised pair of the ridge 52 formed in the rail base 50 The lifting nut 90 is formed at equal intervals along the way and has a square inner circumferential surface as shown in FIG. 4, and a male screw is formed on the outer circumferential surface by screwing into the nut hole 56. A square rod 72 inserted into the inner circumferential surface of the nut 90 extends to the lower end of the pin bolt 70 so that the lifting nut 90 rotates together with the pin bolt 70. By rotating by), while lifting the lifting nut 90 along the nut hole 56 was configured to correct the horizontal of the rail rod (60).

At this time, the male screw formed on the outer circumferential surface of the lifting nut 90, when the pin bolt 70 rotates in the engagement direction with the above-described nut 80, the lifting nut 90 is raised along the nut hole 56, the pin It should be formed in the opposite direction of the male screw formed on the outer peripheral surface of the bolt (70).

That is, the lifting nut 90 rises along the nut hole 56 when the pin bolt 70 and the square bar 72 rotate in the tightening direction, and descend when the pin bolt 70 and the square bar 72 rotate in the opposite direction.

In this way, the lifting lifting nut 90 is screwed to the nut hole 56 formed in the rail base 50, it can be separated from the rail base 50 as necessary.

In addition, the pin bolt 70 is inserted into the inner circumferential surface of the lifting nut 90 in the lower square bar 72 by the spline coupling method, it can be separated above the lifting nut 90 if necessary.

On the other hand, the present invention is installed integrally with the rail base 50 on the outside of the guide plate 54 formed in the rail base 50, non-slip 102: fine projections as shown, for example, but not shown send paper And a side slope plate 100 of a hard metal material such as aluminum having a surface thereof.

At this time, the rail base 50 is protruded upwardly spaced apart from the guide plate 54 at the outside of the guide plate 54, extends from the rail base 50 and protrudes, the spherical fitting projection (58a) at the top A joint piece 58 having a hemispherical fitting groove 104a engaged with the fitting protrusion 58a formed on the joint piece 58 of the rail base 50 on a lower surface of the side slope plate 100. The joint rib 104 having it was formed integrally, and the rail base 50 and the side inclined plate 100 were integrally coupled by the joint piece 58 and the joint rib 104.

That is, the fitting protrusion 58a and the fitting groove 104a of the joint piece 58 and the joint rib 104 are coupled in a ball joint manner, whereby the rail base 50 and the side slope plate 100 are integral with each other. Achieve.

Such, the fitting groove 104 should be formed to be a little smaller than the outer diameter of the fitting protrusion (58a) to ensure the elastic force, and thus the fitting groove (104a) is coupled to the fitting protrusion (58a) by interference fit.

Of course, the fitting groove 104a is expanded with its own elastic force when the fitting protrusion 58a is coupled, and when the fitting protrusion 58a is inserted, the fitting protrusion 58a is pressed by the secured elastic force.

Therefore, the fitting protrusion 58a is firmly coupled by the pressing force of the fitting groove 104a, and thus the joint piece 58 and the joint rib 104 maintain an integrated state.

Thus, the side inclined plate 100 coupled to the outside of the rail base 50 can be installed in a conventional rail base 50 formed differently from the illustration.

That is, unlike the illustrated in the common rail base (not shown) mounted on the rail rod, the joint piece 58 as shown, and the side slope plate 100 having a joint rib 104 according to the present invention ) Can be installed.

In other words, the joint pieces 58 having spherical fitting protrusions 58a formed on the upper ends of the joint rails 58, which are not shown, are formed to extend upwardly, as in the present invention. What is necessary is just to couple the fitting groove | channel 104a of the joint rib 104 formed in the side slope board 100 of this invention to the fitting protrusion 58a.

Then, the side inclination plate 100 of the present invention is integrally coupled to both side surfaces of the conventional rail base by the joint piece 58 and the joint rib 104.

Thus, the side slope plate 100 according to the present invention can be applied to a conventional rail base that is not provided with the nut 80 and the horizontal correction means, which are the components of the present invention.

Here, for example, if the joint piece 58 according to the present invention is formed on both sides of the conventional rail base 12 shown in Fig. 1, the conventional rail base 12 is also according to the present invention. The side slope plate 100 can be installed as described above.

On the other hand, in the present invention, reference numeral 52a in the drawing is a hollow for connecting pin insertion formed in the rail base 50, and inserts the connecting pin (not shown) in the hollow 52a to form another rail base 50. Can be connected continuously.

Further, another reference numeral 104 'is a reinforcing rib for supporting the side slope plate 100 in the long axis direction.

According to the present invention configured as described above, the rail base 50 is fixed to the ground with anchor bolts (not shown), and then the lifting nut 90 is screwed into the nut hole 56 formed on the rail base 50.

Then, the pin bolt 70 is inserted into the through hole 62 of the rail rod 60 to fix the pin bolt 70 with the nut 80, and then the rail rod 60 to which the pin bolt 70 is fixed. Is placed between the ridges 52 of the rail base 50.

At this time, the rail bar 60 should be arranged while inserting the square bar 72 of the pin bolt 70 to the inner peripheral surface of the lifting nut (90).

Then, the pin bolt 70 and the lifting nut 90 are splined by the respective square bars 72 and the inner circumferential surface thereof.

Thus, when the rail rod 60 is arrange | positioned to the rail base 50 as shown in FIG. 3, installation of the rail for a mobile rack is completed.

However, since the rail base 50 and the rail rod 60 where the ground is uneven in the ground cannot be kept horizontal due to the curvature of the ground, the lifting nut 90 is adjusted (rotated) by the pin bolt 70. The horizontal is corrected while raising and lowering?) As shown in FIG.

In more detail, by inserting a driver (not shown) into the screw groove formed on the top of the pin bolt 70 to rotate in the forward direction, the pin bolt 70 rotates the square bar 72 while idling in conjunction.

Of course, the pin bolt 70 is fastened to the lower side, and is idling by the nut 80, which rotates in the nut insertion groove 64 of the rail rod 60.

Then, the lifting nut 90 spline-coupled by the square bar 72 of the pin bolt 70 to be rotated as shown in Figure 5, the rising lifting nut 90 and the pin bolt 70 and Push the combined nut 80 upwards.

Therefore, the nut 80 pushes the rail rod 60 upward, and thus the rail rod 60 is horizontally corrected.

Of course, when the driver rotates in the reverse direction, the pin bolt 70 also idles in the reverse direction, so that the lifting nut 90 descends.

That is, the level of the rail rod 60 is correct | amended by rotating the pin bolt 70 by lifting up the lifting nut 90 with a driver.

As such, as the level of the rail bar 60 is corrected by the lifting nut 90, the rack wheel of the mobile rack not shown may smoothly move along the rail bar 60 maintaining a straight line. It is not separated from the rail rod 60 as shown.

On the other hand, when the horizontal correction of the rail rod 60 disposed on the rail base 50 is completed, the side slope plate 100 is installed on both sides of the rail base 50.

At this time, the side slope plate 100 is easily installed by the joint ribs 104 of the lower surface and the joint pieces 58 of the rail base 50.

Therefore, the mobile rack user is prevented from being caught by the rail base 50 due to the side inclination plate 100, and if the cart is used to transport the goods stored in the mobile rack, the cart is the side inclination plate 100 You can move over to the opposite side of the rail.

As described above, the rail of the present invention is horizontally corrected by the operation of the pin bolt 70 and the lifting nut 90, and the side slope plate 100 is easily installed by the joint rib 104 and the joint piece 58. Can be.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and the scope of application of the present invention is not limited thereto, and may be appropriately changed within the scope of the same idea.

Therefore, the shape and structure of each component shown in the embodiment of the present invention can be carried out by modifying, it is natural that the modification of the shape and structure belong to the utility model registration claims of the present invention attached.

The rail for the mobile rack according to the present invention as described above can easily correct the horizontal level of the rail bar by the lifting and lowering lifting nut, thereby preventing the rack wheel installed in the lower part of the mobile rack from being separated from the rail bar. As the rack wheel moves smoothly along the rails as it is level, the mobile rack can be moved with a small external force.

In addition, since the side slope cover can be easily and conveniently installed on the rail base by the joint pieces and the joint ribs of the rail base and the side slope cover, there is an effect that the workability of the rail can be improved.
