[Detailed explanation of the idea] A. Purpose of the invention (1) Industrial application field The present invention relates to a long object transport device.

(2) Prior Art Conventionally, cargo has been transported by being placed directly on the receiving frame of a pallet handling loader, but it has not been possible to transport long cargo that protrudes from the receiving frame.

(3) Problems to be solved by the invention It would be convenient if long objects could be easily transported using a conventional cargo handling loader.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a long object transporting device that can easily transport long objects.

B. Structure of the invention (1) Means for solving the problem The device of the present invention for achieving the above-mentioned purpose includes a cargo handling loader that has a cargo receiving frame and is movable, and a cargo handling loader that cooperates with the cargo receiving loader to handle long objects. It is equipped with a plurality of auxiliary transport vehicles for transportation, and each of the auxiliary transport vehicles has a mounting plate that receives the bottom surface of the end of the long object protruding from the cargo receiving frame, and a center portion of the mounting plate. and at least three casters attached to the mounting plate near each vertex of the enclosing triangle, and the mounting plates of the auxiliary transport vehicle are removably connected to each other at a predetermined interval. The invention is characterized in that it is provided with a connecting mechanism.

(2) Operation With one end of the long object placed on the receiving frame of the cargo handling loader and the other end of the long object protruding from the receiving frame placed on the placement plate of the auxiliary transport vehicle, When the cargo handling loader is run, the auxiliary transport vehicle also follows the long object and can transport the long object.

In particular, according to the above-described arrangement of the three casters on the mounting plate of the auxiliary transport vehicle, the mounting plate can be supported independently and stably by the casters alone, and can also be turned freely relative to the ground. Therefore, the ability of the auxiliary transport vehicle to follow the turning of the cargo handling loader is improved.

Moreover, since there are a plurality of such auxiliary transport vehicles, and their mounting plates are connected to each other at predetermined intervals, the bottom surface of a long object can be stably covered over a wide range by the group of auxiliary transport vehicles. Supportable. Furthermore, even if a larger moving force is transmitted to some of the multiple auxiliary transport vehicles than the long object due to centrifugal force etc. during turning, it is ensured that the force is transmitted to the other auxiliary transport vehicles via the coupling mechanism. Since it is possible to accurately move and turn each auxiliary transport vehicle in the same direction by transmitting the information to the loader, the turning followability of each auxiliary transport vehicle with respect to the cargo handling loader is further improved. Furthermore, the number of auxiliary transport vehicles to be connected can be determined as appropriate depending on the form of the long object.

(3) Embodiment Below, an embodiment of the present invention will be explained with reference to the drawings. First, in FIGS. 1 and 2, a long object 1 is transported by a pallet handling loader 2 and a pair of left and right auxiliary transport vehicles 3. It is carried along.

The pallet handling loader 2 is a conventionally known one, and includes a single cargo receiving frame 4 in the shape of a long frame, and a front running wheel 5 supported on the tip of the cargo receiving frame 4 so as to be able to rise and fall.
, a base 7 having three caster-type rear running wheels 6 , 6 , 6 , a hydraulic lifting means 9 interposed between the connecting frame 8 standing up from the rear end of the cargo receiving frame 4 and the base 7 , It consists of a raising and lowering operation means (not shown) for raising and lowering the front running wheels 5 according to the raising and lowering of the cargo receiving frame 4 by the operation of the hydraulic raising and lowering means 9, and an operation handle 10 connected to the base 7.

This pallet handling loader 2 can be lifted by inserting a receiving frame 4 into a pallet (not shown), and in the lifted state, it can be moved manually by pushing or pulling the operating handle 10, thereby lifting the pallet on the pallet. It is used to transport cargo, and when transporting long objects 1, it is used with the cargo receiving frame 4 raised.

In Figures 3 and 4, each auxiliary transport vehicle 3
, three casters 12 are mounted on a disc-shaped mounting plate 11,
12, 12 are attached. That is, each caster 12, 12, 12 is rotatably attached to the mounting plate 11 by a plurality of balls 13 near the apex of an imaginary equilateral triangle whose center is located at the center of the mounting plate 11.

A circular recess 14 is provided at the center of the upper surface of the mounting plate 11, and a plurality of, for example, six, connecting grooves 15 extend radially outward from the recess 14.
...are provided radially. Moreover, a through hole 16 is bored in the center of the recess 14, and each connecting groove 15...
As shown in FIG. 5, a plurality of through holes 16 are formed at intervals in the longitudinal direction.

Each connection groove 15... and each through hole 16... are for connecting the auxiliary transport vehicles 3 to each other, and both ends of the connection member 17 as shown in FIG. 6 fit into the connection groove 15, and the through hole 16.

That is, the connecting member 17 is made of a rod having a diameter that allows it to fit into the connecting groove 15, and has engaging portions 18 bent at right angles at both ends that can be inserted into the through holes 16. Therefore, the connecting member 17,
The connecting groove 15 and the through hole 16 cooperate with each other to constitute a connecting mechanism J of the present invention that removably connects the mounting plates 11 of the plurality of auxiliary transport vehicles 3 to each other.

Further, in order to increase the friction coefficient, it is desirable to adhere, for example, a synthetic resin sheet with irregularities to the upper surface of the mounting plate 11.

Next, to explain the operation of this embodiment, when transporting a long object 1, the receiving frame 4 of the pallet handling loader 2 is placed on the loading plate 11 of the auxiliary transport vehicle 3.
The long object 1 is raised to the same level as the upper surface, and one end of the long object 1 is placed on the receiving frame 4.
The other end is connected to each mounting plate 11 of a pair of left and right auxiliary transport vehicles 3.
Place it on top.

In this state, when the pallet handling loader 2 is driven by input by pushing or pulling the operation handle 10, each auxiliary transport vehicle 3 follows and travels through the long object 1, thereby transporting the long object 1. I can do it.

In the above embodiment, two auxiliary transport vehicles 3 are used, but when the width of the long object 1 is particularly large as shown in FIG. , 3 may be connected to each other by a connecting mechanism J, and the other end of the elongated object 1 may be placed on these auxiliary transport vehicles 3, 3, 3. In this way, the long object 1 can be placed stably, and the turning ability of the long object 1 during transportation is excellent.

As shown in FIG. 7, if a pallet receiving loader 2' having a pair of left and right receiving frames 4, 4 extending in parallel is used, one end of the long object 1 can be placed and transported more stably. .

C. Effects of the invention As described above, the device of the present invention includes a cargo handling loader that has a receiving frame and can travel, and a plurality of auxiliary transport vehicles that cooperate with the receiving loader to transport long objects. Each of the auxiliary transport vehicles includes a mounting plate that receives the bottom surface of the end of the long object protruding from the cargo receiving frame, and is attached to the mounting plate near each vertex of a triangle surrounding the center of the mounting plate. The auxiliary transport vehicle has at least three casters, and a connecting mechanism is provided between the mounting plates of the auxiliary transport vehicle to removably connect them at a predetermined interval. Long objects can be easily transported by simply disabling an auxiliary transport vehicle.

In particular, by arranging the casters as described above on the mounting plate of the auxiliary transport vehicle that is driven by the cargo loader via a long object, the mounting plate can be supported independently and stably by the casters, and it can be easily supported against the ground. Since it can be turned freely, it is possible to improve the ability of the auxiliary transport vehicle to follow the turning of the cargo handling loader. Furthermore, since there are a plurality of such auxiliary transport vehicles and their mounting plates are connected to each other at predetermined intervals, the bottom surface of the long object can be supported over a certain wide range by the group of auxiliary transport vehicles. Therefore, even if the long object is wide, it can be placed and transported in an extremely stable manner. Furthermore, even if a larger moving force is transmitted to some of the multiple auxiliary transport vehicles than the long object due to centrifugal force etc. during turning, it is ensured that the force is transmitted to the other auxiliary transport vehicles via the coupling mechanism. Since it is possible to accurately move and turn each auxiliary transport vehicle in the same direction, the ability of each auxiliary transport vehicle to follow the turning of the cargo handling loader is further improved.
There is no possibility that the relative positional relationship between the plurality of auxiliary transport vehicles will change. Furthermore, since the number of auxiliary transport vehicles to be connected can be appropriately determined depending on the form of the long object, it is possible to select the most efficient and optimal usage mode according to the form of the long object.
