While lowering 37, the fixing means 41 is released to remove the device from the object W to be conveyed. By this removing operation, the transported object W is installed on the installation surface as it is.

[0040]

[Effect of device]

 The present invention is configured as described above, and therefore, it can be carried and moved by the wheel mechanism 1 as it is by being lifted by the jack mechanism 30 after being inserted and arranged on the bottom surface of the transported object W. There is no need for a special lifting device such as a jack device as described above, and it is easy to handle. Moreover, the lifted transported object W can be firmly fixed through the fixing means 41, and it can be easily transported or moved. It is safe because the transported object does not drop. Further, during traveling, it can be held after the traveling direction of the steering block 5 having the wheels 4 is adjusted by the direction turning holding means 20 in the wheel mechanism 1, and the setting and holding of the moving direction are reliable, and up to a predetermined installation surface. Mobile traveling can be performed easily.

That is, in this invention, in this invention, the wheel mechanism 1 having the wheels 4 that can turn in the direction and retain the direction after turning, and the predetermined object W to be conveyed are fixed. This is because it consists of a jack mechanism 30 that lifts above the installation surface and the moving surface in the above state. As in the conventional case, a so-called speed roller with a caster structure and a lifting device are separately prepared. There is no need to do it. Moreover, since a plurality of the devised devices are combined to lift and move the object W to be transported, the jack mechanism 30 needs only a small lifting capacity, and the handling as a whole is easy and the workability is greatly improved. Can be made.

Further, since the wheel mechanism 1 is provided with the base 2, the wheel portion 3, and the direction-turning holding means 20, it is possible to move the transported object W while lifting it by the wheel portion 3, and By the universal joint means 10 of the ball pair structure in the wheel portion 3, only the wheel portion 3 can be swung up and down with respect to the base 2, so that even if the conveyance surface has irregularities or the like, it can be smoothly moved. It is possible to follow, and the transferred object W can be smoothly moved and transferred without being greatly inclined.

Further, the direction-turning holding means 20 is elastically movably and swingably attached to the front portion of the steering block 5 at positions where the plurality of holding holes 21 are formed on the front edge surface of the base 2 having an arc shape. Since the engagement pin 22 of the supported swing operation lever 23 is detachably fitted, the swing operation of the swing operation lever 23 causes the engagement pin 22 and the holding hole 21 to engage or disengage and swing. By turning the steering block 5 by the motion control lever 23, the steering block 5 can be directed in an arbitrary moving direction and the turning position after setting the traveling direction can be held.

On the other hand, the jack mechanism 30 includes a lift fork plate 37 for mounting and supporting the transferred object W and a fixing means 41 for holding and fixing the transferred object W, which is moved up and down through the jack section 31 and the guide section 38. Since it is provided, the transported object W on the lift / fork plate 37 is lifted by the action of the hydraulic pressure for ascending / extending, and the transported object W is lowered by the cancellation of the ascending action after the moving / conveying, and the transported object W is placed on the installation surface. It can be installed as it is.

At this time, in the lift fork board 37, the placing portion 37A on which the transported object W is placed is on the lower side, the connecting portion 37C which is connected to the jack rod 35 of the jack portion 31 is on the upper side, and the upright standing state. -Shaped slide portions 37B are formed in an appropriately thick metal plate material having a generally S-shape when viewed from the side faces each having a central slide portion 37B, so that insertion into the bottom surface of the transported object W is facilitated, Further, the ascending action of the jack portion 31 after the insertion is smoothly performed by the slide portion 37B itself which is guided up and down by the guide portion 38.

Since the stopper body 42 of the fixing means 41 in the jack mechanism 30 is formed in a flat gate shape that is in the form of a straddle that meshes with the positions of both side edges of the mounting portion 37A of the lift fork plate 37, the stopper body 42 is conveyed. It can be adjusted to its own position corresponding to the object W and can be engaged in a projecting state on the placing portion 37A, so that the transferred object W 1 placed on the placing portion 37A can be securely engaged from inside the lower end portion thereof. Can be combined. Further, since the slide pad body 45 is connected with the press contact pad 47 via the joint of the ball-pair structure to the tip of the feed screw 46 that can advance and retreat to the slide portion 37B of the lift fork plate 37, the transported object W It can be properly fitted to both the inclined surface and the vertical surface. Therefore, in the fixing means 41, when the stopper body 42 engages the conveyed object W, the slide pad body 45 presses the conveyed object W together, so that the conveyed object W is moved to the lift fork board 37. Since the object W can be firmly fixed, there is no risk of the transferred object W falling during the transfer operation, and the transfer operation can be safely performed.
