  The present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a transporting device that can transport a heavy load with a small forklift, with few shape restrictions, and easily and inexpensively. To do.

  In order to achieve the above object, according to the first aspect of the present invention, there is provided a transport cart (2) having a pair of wheels (22) in the width direction at one place in the longitudinal direction excluding one end (25), and a transport cart (2). A first connecting member (3) provided at one end (25), and a second connecting member (4) removably attached to a lifting fork (F1) of a forklift (F). When F1) rises, this pushes up one end (25) of the transport carriage (2) through the first connecting member (3), and the second connecting member (4) is in a horizontal plane with respect to the first connecting member (3). Relative rotation is possible and relative movement in the horizontal direction is engaged in a restricted state.

  According to the first aspect of the present invention, since the load is placed on the carriage, the shape is not restricted, and even a heavy load can be easily conveyed by a small forklift. In particular, it is possible to realize a transport cart simply by using a loading platform of a used truck and providing a connecting member on it. Compared to purchasing a transport truck, etc. by connecting the transport cart with an existing forklift. Thus, the cost can be significantly reduced. In addition, the forklift and the transport cart can be rotated relative to each other in the horizontal plane and connected in a state where the relative movement in the horizontal direction is restricted, so that the forklift can be freely transported taking advantage of the running performance and turning performance of the forklift. is there. Also, if the load is placed near the wheel of the carriage, even if the load is heavy, the load applied to the lifting fork can be kept small by the lever principle, which also increases the size of the forklift. Can be avoided.

  In the second invention, in the first invention, the second connecting member (4) is engaged with the first connecting member (3) by the shaft body (33) and the connecting hole (41) into which the shaft body (33) relatively enters. According to the second aspect of the present invention, the connection structure can be easily realized.

  In the third invention, in the second invention, alignment means (42, 43) for aligning the shaft body (33) and the connecting hole (41) in the horizontal direction is provided. According to the third aspect of the invention, the forklift and the transport cart can be easily and reliably connected.

  The reference numerals in the parentheses indicate the correspondence with specific means described in the embodiments described later.

  According to the transport device of the present invention, a relatively free-form heavy object can be transported easily and inexpensively with a small forklift.

It is a whole side view of the conveyance apparatus of the state connected with the forklift which shows one Embodiment of this invention. It is a perspective view of a connection member. It is a whole side view of the conveyance apparatus at the time of package conveyance.

  FIG. 1 shows an overall side view of the transport device 1 in a state of being connected to the forklift F. The transport device 1 includes a transport cart 2, and the transport cart 2 has a rectangular shape when viewed from above. A rear end (other end) 21 of the transport carriage 2 is supported by wheels 22. In other words, a pair of wheels 22 are disposed below the rear end 21 of the transport carriage 2 in the width direction of the carriage 2, and these wheels 22 are coupled by the same axle 23. And the top part 241 of the leaf | plate spring 24 (only this side is shown) which protrudes and curves below is fixed to the both ends (front side and other side of drawing) of the axle housing (not shown), and both ends of the leaf spring 24 are fixed. 242 and 243 are fixed to and supported by the lower surface of the rear end 21 of the carriage 2. Such a transport cart 2 can be realized at low cost, for example, by reusing a truck bed that has been scrapped.

  A connecting member 3 is provided on the lower surface of the front end (one end) 25 of the transport carriage 2. The connecting member 3 has an inverted L shape in a side view, and the vertical portion 31 serves as a support leg extending downward at both ends in the width direction, and supports the front end 25 of the transport carriage 2. The height of the support leg 31 is slightly lower than the rear end 21 of the transport carriage 2. A shaft body 33 protrudes downward from the horizontal portion 32 of the connecting member 3, and an alignment pin body 34 stands at a position corresponding to the shaft body 33 on the upper surface of the horizontal portion 32. It is.

  On the other hand, a connecting member 4 is attached to the fork F1 for raising and lowering the forklift F. A perspective view of the connecting member 4 is shown in FIG. The connecting member 4 is formed into a rectangular box-shaped plate body, and a circular connecting hole 41 penetrating in the vertical direction is provided at the center of the plate surface. An alignment stand 42 is installed on the upper surface of the connecting member 4. The stand 42 is formed by bending a bar material into a substantially inverted L shape, and a chain 43 is suspended from the distal end portion 421 that has caused blood to reach the lower part thereof toward the substantial center of the connecting hole 41.

  An insertion port 44 in which guide pieces 441 protrude from both sides of the opening is opened at one side of the connecting member 4 at the left and right positions. Therefore, the horizontal portion F11 of the lifting fork F1 of the forklift F is inserted into each of the insertion ports 44 (only one lifting fork is shown in FIG. 2), and the stopper pin 45 is inserted into the hole 442 at the tip of the guide piece 441. By inserting and spanning the stopper pin 45 between the guide pieces 441, the stopper pin 45 comes into contact with the back of the lower end of the inserted lifting fork F1, and the lifting fork F1 is prevented from coming off from the insertion port 44. The In this way, the connecting member 4 is mounted on the lifting fork F1. In order to prevent the stopper pin 45 from being lost, the connecting member 4 may be provided with a storage portion and stored therein.

  When transporting a load with the transport device 1 having the above-described structure, the load W is placed on the transport cart 2 (FIG. 1) so that the connecting member 4 is positioned slightly lower than the tip of the shaft 33 of the connecting member 3. Lower the lifting fork F1. Thereafter, the forklift F is moved so that the lower end of the chain body 43 of the connecting member 4 comes to a position immediately above the pin body 34 of the connecting member 3. In this way, the position of the connecting hole 41 of the connecting member 4 and the position of the shaft body 33 of the connecting member 3 are matched in the horizontal direction. In this state, the lifting / lowering fork F1 is raised to bring the shaft body 33 into the connecting hole 41. Relatively approach (in the state of FIG. 1). As a result, the connecting members 3 and 4 are engaged with each other in a state in which the connecting members 3 and 4 can rotate relative to each other in a horizontal plane and the relative movement in the horizontal direction is restricted, and the forklift F and the transport carriage 2 are connected.

  When the lifting fork F1 of the forklift F is further raised, the horizontal portion 32 of the connecting member 3 is pushed up by the connecting member 4 as shown in FIG. 3, and the front end 25 of the transport carriage 2 is also pushed up together with this. In this process, the lower end of the support leg 31 of the connecting member 3 moves upward from the road surface. Therefore, when the forklift F is moved, the transport carriage 2 carrying the load W is also connected to the forklift F and moves.

  As described above, according to the transport device 1 of the present embodiment, since the load W is placed on the transport cart 2 soil, simple transport by the small forklift F is possible without being restricted in shape. In particular, since a transport truck 2 can be realized simply by using a loading platform of a used truck and providing a connecting member 3 on this, a transport truck or the like can be purchased by connecting the transport truck 2 to an existing forklift F. Compared with this, the cost can be significantly reduced. Further, since the forklift F and the transport carriage 2 are connected to each other in a horizontal plane and the relative movement in the horizontal direction is restricted by the shaft body 33 and the connecting hole 41, the forklift F travels. It can be transported freely utilizing its performance and turning performance. Further, if the load W is placed near the wheel 22 of the transport carriage 2, even if the load W is heavy, the load applied to the lifting fork F1 can be kept small by the lever principle. Also, an increase in the size of the forklift F can be avoided.
