The present invention relates to a conveying device for a heavy object such as a bridge. In general, when constructing a railway bridge over a river or a valley, a concrete foundation is built in the river, a bridge is laid on the foundation, and a rail facing the rail on the ground is provided on the bridge. The bridge is very heavy by weight, so when it is laid on the foundation of concrete, it has to be moved from the ground to the foundation in the longitudinal direction, or assembled on the foundation and then pushed from the side to the position opposite the ground rail. Is considered. Therefore, in the case of moving a heavy object of such a bridge to, for example, a hydraulic system, the hydraulic system must be supported on the side opposite to the heavy object as a reaction thereof. Although it can be seen from Japanese Patent Publication No. 50-5123, etc., all of these devices have a disadvantage in that they are complicated in structure, difficult to design, disadvantageous in terms of production, and also have insufficient gripping force.

In addition, conventionally known heavy structures are moved by interposing a roller and a bogie on a moving main road of the heavy structure, allowing the heavy structures to be placed on the rollers and the bogie, and winding a rope connected to the heavy structure by a winch. This heavy structure is to be conveyed by putting in. However, in this kind of conveying method, since several rollers and trolleys must be arranged on the moving main road, and a large winch must be used, the facility itself becomes extremely large and disadvantageous in terms of cost. Moving heavy structures between the rollers and the bogie has the disadvantage that the direction is not determined.

For this reason, in order to solve such a conventional fault, the conveyance apparatus of the heavy material of Japanese Unexamined-Japanese-Patent No. 56-17242 is known, for example. The conveying device connects a hydraulic cylinder to one end of the shoe, and a gripping device to the other side of the hydraulic cylinder. The gripping device includes a holding cylinder standing on a support plate, and a rotating cylinder supported on both sides of the holding cylinder. The hook-shaped hook and the operation cylinder supported by the holding cylinder and connected to the hook are operated to operate the two holding cylinders and the operation cylinder so that the hooks can be attached to and detached from the H-shaped rail pulley. When the hydraulic cylinder is extended, the shoe moves in the longitudinal direction. However, while the conveying apparatus of such a heavy object has a large holding force and a high pressure, a rail having an H cross section is required to support the hook-shaped hook, and the rail needs to use a durable member by increasing its strength. In addition, since the seat height of the rail requires a seat height enough to be hooked, the structure of the rail itself is complicated, material costs are increased, and production is disadvantageous in many cases. In addition, the hook-shaped hook and its driving device are complicated in structure, and there are many parts, and there is a problem to be improved in workability or economy.

It is therefore an object of the present invention to provide a conveying apparatus for heavy materials which is simple in structure, excellent in workability, economical efficiency, and has sufficient gripping force, which can be conveyed not only on flat ground but also on slope.

In order to achieve this object, the present invention stands up the connecting plates on both sides of the rail, and forms the connecting portions formed by grooves or holes in the connecting plates at arbitrary intervals, while supporting the supporting cylinders to convey the heavy materials. The stopper and the stopper driving drive stopper cylinder are installed in this support part, and when the stopper is moved through the stopper cylinder, the stopper is attached to and detached from the edge part.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The heavy weight conveying apparatus 1 according to the best embodiment of the present invention comprises a rail 2, a connecting plate 3 standing on either side or one side of the rail 2, and a conveying member for conveying the heavy weight 4; In Shu (5), Shu. The conveyance cylinder 6 and the engaging part 7 which support the base end of the conveyance cylinder 6 to the connecting plate 3 for detachable material are comprised.

The rail 2 is formed by fixing a slide plate 9 made of stainless steel or the like on an upper surface of a plate 8 made of a thin metal or the like, and connecting plates 3 are erected on both sides of the plate 8 in a longitudinal direction. In this connecting plate 3, connecting grooves 1, which are several connecting portions, are formed at arbitrary intervals, for example, at equal intervals.

The shoe 5 forms two fitting grooves 12 in the center of the lower end of the rectangular main body 11, and fits the spacer 13 and the supporter 14 to the fitting grooves 12, and supports them. The slide plate 15 which is smoothed with Teflon or the like is supported on the lower surface of the ash 14 so that the shoe 5 slides in the longitudinal direction on the rail 2 via the slide plate 15. At this time, both side surfaces of the shoe 5 are guided to the connecting plate 3 so as not to derail laterally from the rail 2.

The heavy material 4 is placed on the upper surface of the shoe 5, and the heavy material 4 is also transferred in the same direction as the shoe 5 moves. In addition, it is preferable to install the same catching part as the catching part 7 which is connected to the connecting groove 10 with a detachable material at the side or front end of the shoe 5, for example.

A bracket 16 protrudes from the right end of the shoe oil 5, and a piston rod 17 of the transfer cylinder 6 is connected to the bracket 16 via an eye 18. The conveying cylinder 6 is comprised of the cylinder 19 and the piston rod 17 slidingly inserted through the piston in the cylinder 19, and the inside of the cylinder 19 is divided into two pressure chambers separated by the piston. The pressure chambers are connected to the hoses 20 and 21 so that a pressure source such as oil or air is supplied to and discharged from one of the pressure chambers.

The support part 22 is fixed to the right end of the cylinder 19, and the stopper cylinder 23 is supported to the right end of this support part 22 in the vertical direction. A groove 24 is formed in the center of the outer circumference of the support portion 22, and the locking piece 7 is supported in the groove 24. The locking part 7 is composed of a support plate 26 and a connecting member 25 having a bifurcated shape as a stopper. The connecting member 25 extends horizontally from the supporting plate 26 so that an end thereof is a piston of the stopper cylinder 23. Coupled to the rod 27, the support plate 26 is guided to the groove 24 to move up and down in accordance with the expansion and contraction of the stopper cylinder (23).

A step portion 28 is formed on the bottom surface of the outer end of the support plate 26, and when the support plate 26 is lowered, the step portion 28 is in contact with the bottom surface of the connecting groove 10.

Next, the operation will be described.

Assume that the conveying cylinder 6 is now being compressed. In this state, the heavy material 4 to be conveyed is placed on the shoe 5, and the stopper cylinder 23 is compressed to engage the support plate 26 with the connecting groove 10. Next, when the conveying cylinder 6 is extended, the piston rod 17 pushes the shoe 5 to the left, and the shoe 5 advances on the rail 2 with the heavy material 4 loaded thereon. Is equal to the amount of extension of the piston rod 17. Moreover, when the shoe 5 advances, the reaction force acts on the conveying cylinder 6, but since the base end of the conveying cylinder 6 is supported by the support plate 26 via the connecting groove 10, this reaction force is a rail ( 2), the cylinder 19 of the transfer cylinder 6 does not move.

Next, the stopper cylinder 23 is extended, the support plate 26 is peeled off from the connecting groove 10, and the transfer cylinder 6 is compressed. At this time, the shoe 5 is stopped on the rail 2 by the weight 4 and its own weight, and the cylinder 19 and the engaging parts 7 are pulled to the left and left. In the case where the heavy material 4 is left in this position, the stopper cylinder 23 may be compressed, the support plate 26 may be lowered to fit the connecting groove 10, and the conveying cylinder 6 may be extended again.

That is, the conveyance of a heavy object may repeat the expansion | contraction of the conveyance cylinder 6, and the attachment / detachment operation of the support plate 26 with respect to the connection groove 10. FIG. In addition, when the same catching parts as the catching parts 7 are installed in the shoe 5 and the catching parts are operated synchronously, the cylinders 19 and the catching parts 7 are pulled to the left. Since the engaging parts on the side of the shoe 5 are supported by the connecting groove 10 of the connecting plate 3, the cylinder 19 and the like can be pulled out with the shoe 5 completely stopped. The catching part on the shoe 5 side is installed on the shoe side to be stretched in the horizontal direction by a cylinder or the like, and may be synchronized with the catching part 7 on the conveying cylinder side or operated independently, or by manual operation. You can do it.

Next, FIGS. 4 to 6 relate to a conveying device of a heavy product according to another embodiment of the present invention.
