Referring to the operation of the leveling device according to the present invention as described above is as follows.

1 and 2 show the state that the lifting plate 10 is raised by the X lever 105 of the X lever-type lifting means 100 is extended, for example, a truck having a high loading box is the ground 1 of the arrival hall. In the case of entering the postal transport cart on the lifting plate 10 in advance, elevating the lifting plate 10 to match the height of the lifting plate 10 to the bottom surface of the loading box of the truck, and then loaded in the loading box Move the mail to the cart.

In addition, when the lifting plate 10 is raised in this way, the extension plate 301 of the extension latching means 300 protrudes forward by the operation of the cylinder 306 so that the front end of the extension plate 301 is loaded with the vehicle. Since there is no space between the stacker and the lifting plate 10 because it is spread across the floor surface, the worker can work safely, and also because the safety plate 201 of the safety catching means 200 protrudes upward, the transport cart is slipped. Even when reversing, the safety plate 201 does not fall and fall, thereby enabling safe work.

In this way, after moving the postal matters to the transport cart, the cylinder 114 is reduced, and the roller 108 fixed on the upper end of the lever A 102 and the roller 110 fixed on the lower end of the other lever B 103 are elevated. One lever A 102 and the other lever B 103 are centered on the bearing portions 106 and 109 while moving forward by taking the rail 107 of the 10 and the rail 111 of the base plate 101. As it rotates in the counterclockwise direction, the X lever 105 is folded, whereby the elevating plate 10 moves downward.

As such, when the lifting plate 10 is moved downward so that the lifting plate 10 coincides with the moving road surface 2, the transport cart on the lifting plate 10 is safely transferred to the moving road surface 2 to process the mail. Mail will be carried inside the building.

In addition, when the height of the bottom surface of the loading box is the same as the moving path surface 2, the lifting plate 10 is lowered to the same height as the moving path surface 2, and the bottom surface of the loading box of the transport vehicle is performed. If the height is in the middle of the upper and lower positions of the elevating plate 10, the lifting plate 10 is adjusted to the intermediate height to carry out the mail conveying operation.

The safety locking means 200 is operated in conjunction with the lifting plate 10 by folding the X lever 105, the safety plate 201 is raised upward when the lifting plate 10 as shown in Figure 4 Will be. When the X lever 105 is further folded in the state of FIG. 4, the supporting rod 214 of the protruding length adjusting means 210 coupled to the one lever A 102 as shown in FIG. 5 is in contact with the rotation lever 203. In this case, the spring 209 is reduced. Then, when the X lever 105 is further folded, the safety plate 201 moves downward as the pivoting lever 203 is rotated by the supporting rod 214, and the X lever 105 is further folded as shown in FIG. 6. When the lower elevating plate 10 is lowered to the height of the moving path surface 2, the safety plate 201 is completely inserted into the lower portion of the elevating plate 10, thereby preventing movement of the transport cart.

In the state of FIG. 6 again, when the X lever 105 is unfolded and the lifting plate 10 is raised, the pivot lever 203 is supported by the spring 209 as the one lever A 102 rotates as shown in FIG. 5. It rotates together in contact with the rod 214, whereby the safety plate 201 protrudes upward. Subsequently, when the X lever 105 is further rotated, the safety plate 201 completely protrudes, and when the X lever 105 is further rotated, the spring 209 is extended to safely hold the safety plate 201 and as shown in FIG. 4. When the steel plate 10 rises to an upper limit position, an ascending operation is complete | finished.

Meanwhile, when the lifting plate 10 is lowered to the same height as the moving path surface 2 by being folded on the X lever 105 as shown in FIG. 6, the safety plate 201 is lowered to the inside of the lifting plate 10. By doing so, the transport cart on the elevating plate 10 is not caught when moving to the moving path surface 2, and the descending degree of the safety plate 201 is projected length adjusting means according to the height of the moving path surface 2 ( 210).

That is, the moving path surface 2 of the postal processing plant may be high or low depending on the circumstances of the site when it is based on FIG. 1, and the safety plate 201 may be used even when the height of the moving path surface 2 is different. When the lifting plate 10 is lowered is always lowered by the protrusion length adjustment means 210 is inserted below the lifting plate 10 so as not to interfere with the movement of the transport cart.

7 and 8 are views showing the action of the protruding length adjusting means, as shown in FIG. 7 by loosening the bolt 213 of the protruding length adjusting means 210 and holding the fixing plate 211 upward to fix the support rod 214. When the position is adjusted higher than FIG. 6, the pivoting lever 203 rotates clockwise to lower the height of the safety plate 201, and is supported by lowering the fixing plate 211 downward as shown in FIG. 8. When the position of the rod 214 is adjusted lower than that of FIG. 6, the rotation lever 203 is further rotated counterclockwise as much as the height of the safety plate 201 is increased.

The present invention as described above is installed at the entrance side of the moving road surface of the postal processing plant and automatically adjusts the height of the lifting plate according to the height of the loading box of the postal transport vehicle, so that the bottom surface of the loading box and the lifting plate and the moving path surface are the same. By coinciding on the plane, it is very easy and convenient to load the postal items loaded on the transport vehicle into a trolley and carry them into the building of the postal processing plant.

In addition, since the extension plate is automatically protruded from the tip of the lifting plate when the lifting plate is raised to the working position, so that there is no space between the loading box and the lifting plate, there is an advantage that the transport operation can be safely performed.

In particular, the safety plate is automatically protruded from the rear end of the elevating plate when the elevating plate is raised to the working position to prevent the transport cart from slipping and falling, there is an advantage that the carrying operation can be performed more safely.

In addition, when the stroke of the elevating plate is changed according to the height of the moving path surface of the work site on which the device is installed, the position where the safety plate is lowered and inserted is advantageously easily adjusted by the protruding length adjusting means.

Therefore, the leveling device of the present invention saves the number of people and time for mail transport and delivery work and can work very safely, thereby improving the work efficiency.
