Description

[Detailed description of the invention] (a) Industrial application field The present invention is convenient for transporting heavy objects, and can be applied to both large and small objects. The structure is simple and strong, so it has excellent durability and does not break down, and for large machines, three or more parts can be distributed on the floor and connected to the bottom of the machine, making it easy to transport. Therefore, small and heavy objects can be easily transported by this method.

(b) Prior Art and Problems There are many conventional devices for transporting heavy objects, but most of them are moved by a drive chain, and are therefore easily damaged and expensive. Cart-type carts also exist, but they require a lot of manpower to load heavy objects and have the disadvantage of being easily damaged. For example, Jitko No. 50-8854 or Jitko No. 47-
It is like No. 37505.

(c) Structure of the present invention In the present invention, a central partition wall 2 is provided between the left and right side walls 1, 1 of a rectangular box-shaped frame made of iron material and parallel to the left and right side walls 1, 1. Then, shaft through holes 3, 3 perpendicular to the left and right side walls 1, 1 and the central partition wall 2 are bored at a predetermined interval to allow the plurality of rotating shafts 4, 4 to pass through them, respectively. (This required spacing is a distance that allows the wheels 6, 6 to be wrapped and fixed integrally with the rotating shafts 4, 4 to rotate freely.) The rotating shafts 4, 4 are Bearings 5 provided in each hole 3 allow for free rotation.

The rotating shafts 4, 4 are provided with four peripheral walls, each having a wheel 6, which is integrally wrapped and fixed with the rotating shaft 4, between the left and right side walls 1, 1 and the partition wall 2, respectively, so as to be rotatable together with the shaft. The outer periphery of the wheel should protrude from the lower end. The wheels 6 are integrally wrapped with metal and fixed to the rotary shaft 4, and rotate together with the rotary shaft 4. However, when the surface of the wheels 6 is wrapped with polyurethane rubber 19, it is possible to reduce noise and improve the floor surface when transporting heavy objects. It has the effect of not harming others.

Further, in either one of the rotating shafts 4, 4, an end portion 7 extending outward of the side wall 1 is formed into a hexagonal to octagonal chamfered portion 8. (Insert the ratchet handle into this to start the machine.) In addition, a fitting hole 10 is provided in the center of the top plate 9, which is the bottom of the box shape, and a support shaft 12 is hung down in the center of a rotary plate 11 provided separately. It is rotatably inserted into the insertion hole 10, and a screw hole 13 for a bolt is formed in the support shaft 12 of the rotary disk 11.

Furthermore, one of the front and rear side walls 14, 14 has a fitting hole 1.
This relates to the structure of a heavy object transfer device characterized in that a required number of tongue rods 16 having a diameter of 5 are protruded.

(d) Operation and effect of the present invention The structure of the present invention is made of iron materials and formed into an inverted box shape with left and right side walls 1, 1, front and rear side walls 14, 14, and a top plate 9, and a central partition wall 2 is provided, and the left and right side walls are Shaft through holes 3, 3 perpendicular to the central partition wall are bored at required intervals, and a plurality of rotating shafts 4, 4 are passed through these, respectively, and rotatable by bearings 5 provided in the shaft through holes, Left and right rotation shafts 4, 4 between the left and right side walls and the partition wall
Since the wheel 6 is made of a steel plate of the required thickness that is integrally wrapped and fixed to the rotating shaft by welding or the like, there is no risk of breakage during use as with conventional drive chain type and other structures.
It has the characteristics of high durability and can be manufactured at low cost.

When the wheels 6 are wrapped with polyurethane rubber 19 on their surfaces, there is an effect of muffling noise and preventing damage to floors and other surfaces when transporting heavy objects. And wheels 6
Since the outer periphery of the wheel protrudes from the lower end of the four peripheral walls, there is no problem with rotational transfer.

Furthermore, when transporting a large machine, use three or more of the proposed products at the same time, and insert the bolts 18 into the base bolt holes of the machine frame 17 as shown in Figure 4.
Insert these bolts 18 into the main turntable 1.
1, the bolts are inserted into the bolt insertion holes 13 and tightened to stabilize the heavy object and prepare for transport.

In the case of small and heavy items, it is often possible to make do with just one item.

Therefore, in order to transfer a heavy object, it is necessary to start the present invention, but either one of the rotary shafts 4, 4 of the present invention has an end 7 extending outward of the side wall 1 with a hexagonal or octagonal surface. Since the ratchet handle has a chamfered part 8, when the insertion part of the ratchet handle is inserted into the chamfered part 8 of the end part 7 and rotated, the device supporting the heavy object will start, and all that is left is to push the heavy object itself. There are characteristics that can be obtained by transport.

Furthermore, in this case, a required number of tongue rods 16 having insertion holes 15 are protruded from one of the front and rear side walls 14, 14, so that a strong rope or the like is inserted into the insertion holes 15 to continue towing and transporting. There are characteristics that can be used.

In addition, this proposal has an insertion hole 10 in the center of the top plate 9 in the shape of an inverted box.
A support shaft 12 is provided in the center of the rotary disk 11 so as to hang down and be rotatably inserted into the center of the rotary disk 11.
Since a screw hole 13 for a bolt is provided inside, a screw hole 13 for supporting a heavy object to be transferred can be inserted into the rotary plate 1.
It has a feature that it can be screwed in smoothly by turning 1.

In addition, when using this device, when changing its direction, insert a jack next to the device and lift the transferred object, and the device will be lifted at the same time. As it rotates, the jack is then removed, and in the same way, the other side of the object to be transferred is lifted, the main part attached to the other side is turned in the same direction as the main part on the one side, and then the object to be transferred is lowered to the floor. By pushing the object again, the direction can be changed in the desired direction, making it extremely suitable as a heavy object transfer tool.
