Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet movement assisting device, and more particularly to a pallet movement assisting device which is inserted into an opening of a pallet and inserted into a ring at a hand portion of the pallet moving assisting device, whereby the entire pallet moving assisting device is raised. The present invention relates to a pallet movement assisting device capable of moving a load along with a pallet while the load is placed on the pallet with the handle attached to a handle insertion pipe at a hand portion.

[0002]

2. Description of the Related Art Expressways have been developed and distribution routes throughout the country have been improved.
Transportation work is taking place. When loading and unloading luggage in trucks and warehouses in conjunction with the increase in transportation and hauling operations, luggage is piled up on wooden or plastic pallets, and loaded with luggage. At present, pallets are loaded and unloaded using forklifts and cranes, and the packages are now loaded on trolleys and carried manually.

[0003]

However, when working with a heavy pallet on which a load is placed using a forklift or a crane, the work space is limited or the work place faces the road. For example, when working with a forklift, it is necessary to work while avoiding other passing vehicles and passers-by, and it is necessary to unload efficiently in as short a time as possible. Also, when the truck carrying the load is a hood or a truck with an aluminum enclosure, it is sometimes difficult to use a forklift. Further, at the time of unloading, depending on the parking situation of the truck, it is often the case that the truck can be unloaded only from one side or the rear of the truck. In the case of a truck having a deep bed and a long bed, luggage at a position where the tip of the forklift does not reach must be manually moved from the tip of the bed, and the labor of the operator is enormous.
In addition, the worker needs a great deal of labor to subdivide the unloaded luggage and carry it in manually, or to load the luggage on a trolley and change the luggage while pushing the trolley manually. In addition, not only unloading from trucks, but also movement of luggage on pallets loaded in warehouses had to be carried on a trolley and carried in manually each time. Therefore, the emergence of a pallet movement aid that can easily move a load on a heavy pallet on a truck bed or in a warehouse is strongly desired at present.

2, the wheel covers 31a are connected to the receiving shafts 30a, 30a.
a. And the wheel covers 31a, 31
Wheels 29a, 29a are mounted in a. The lower portions of the wheels 29a, 29a are formed so as to be located below the center of the recessed center portion of the wheel cover 28a. That is, the wheels 29a, 29a are configured to be in contact with the ground, but the central concave portion of the wheel cover 28a is configured not to be in contact with the ground. In the above embodiment, the configuration of the hand portion of the wheel portion of the pallet movement assisting device has been described. As shown in FIG. 10, the wheels 2
The wheel covers 31b, 31b to which 9b, 29b are attached are integrally formed by direct welding or the like.

(Function 1) Opening 36 of double-sided pallet 34
When the auxiliary tool is inserted into the opening 36a of the double-sided pallet 34, the opening of the auxiliary tool from the tip of the auxiliary tool is made in a state where the auxiliary tool is tilted sideways in advance when the auxiliary tool is inserted into the opening 36a of the double-sided pallet 34 because the a and b are formed in the horizontally long slots. The auxiliary tools are inserted from 36a, 36a, and when the tips of the auxiliary tools come out of the openings 36b, 36b, both the auxiliary tools are erected as shown in FIG. At this time, both wheels 12a, 1
2b is adhered to the ground, but the connecting pipe 24 is located at approximately the middle of the height between the openings 36a and 36b of the double-sided pallet 34. Then, the crank handle 37 is inserted into the rings 25, 25 at the hand of the auxiliary tool and rotated. Then, the screw rod 16 rotates with the rotation of the ring 25 and rises from the inside of the square screw cylinder. At this time, by bevel gear transmission,
Since the rod 22 fixed to the bevel gear 21a rotates, the bevel gear transmission mechanism at the tip of the assisting tool also operates, and the screw rod 2
7 also rises inside the square screw cylinder at the same time, and both cases are raised upward. Then, if the connecting pipe 24 stops against the upper part of the opening of the double-sided pallet 34 and stops rotating the crank handle 37 when the double-sided pallet is pushed upward, as shown in FIG. 34 is lifted from the ground. Then, both vertical portions of the handle 33 are inserted into the handle insertion tubes 26, 26, and the pallet can be moved with the load placed on the double-sided pallet 34 manually. The handle 33
The width of both vertical parts of the handle is 2
The center of the handle 33 can be adjusted to extend and contract in the horizontal direction so as to have the same width as that of the handles 6 and 26.

(Function 2) A state of use of a pallet movement assisting tool used for a pallet without a lower surface and a net pallet according to the second embodiment of the present invention will be described. Since the heights of the openings 36a and 36b of the pallet 35 having no lower surface are low, in the case of this auxiliary tool, both wheels are attached to both sides of the case, respectively, and there is no lower surface from the tip portion even if the auxiliary device is not turned sideways. It only has to be inserted into the opening 36a of the pallet 35,
When the tip of the assisting tool comes out of the opening 36b, the ring 25 is rotated by the crank handle 37 to simultaneously raise the hand case 1a and the tip case 1b of the assisting tool so that the upper surface of the connecting pipe 24 has the lower surface. No pallet openings 36a, 36
If the auxiliary tool lifts the pallet 35 against the upper surface of the pallet 35b, the handle 33 is inserted into the handle insertion tube 26, and the pallet 35 is moved with the luggage placed thereon manually. This is the same as the case of the operation 1.

Using the aid of the present invention to arrive at the destination,
After moving the pallet and unloading the load, the auxiliary tool is lowered by rotating the ring again with the crank handle and lowering the screw rod. It is detached from the upper surface of the opening of the pallet, extracted from the pallet, and used for the next pallet.

[0014]

According to the present invention, a bevel gear is meshed with the auxiliary tool having a vertical ascending / descending function so as to be perpendicular to the wheel shaft, and the bevel gear transmission mechanism can be securely fixed in the auxiliary tool insertion port of the pallet. The pallet can be easily moved with the aid of the present invention simply by being inserted, and there is no need to use a forklift or a trolley as in the related art. No special equipment or external power source is required, so there is no cost. Since it is a lightweight and compact pallet movement aid, it can also be used in warehouses with limited working space and in loading platforms such as trucks. Further, when unloading from a truck as in the prior art, there is no need to carry the luggage on the pallet in small portions, and the work labor can be greatly reduced.
