[Industrial applications]

 The present invention relates to a material hoisting device that can hoist a load while correcting misalignment of a plurality of hoisting loads, and that can quickly unload the material at a transport position.

[0002]

[Prior art]

 At the recent building construction site, in order to streamline the loading work, for example, beam members, floor slabs, etc. are collectively lifted and loaded in 3 to 4 pieces. In this hoisting work, the hoisted load is surrounded by a pair of hoisting wires, and each hoisting wire is slung on the hook of the crane wire to hoist it. Therefore, if 3 to 4 pieces are hoisted together, the appearance of the hoisting load is unstable. Since there is a risk that they will fall apart and fall, in the past, the pieces were connected by bolts or nuts or fixed in a tight state with a band and then lifted.

[0003]

[Problems to be solved by the device]

 However, although this method has certainty for preventing a fall accident, it does not necessarily lead to the rationalization and speeding up of the work, because the work of unpacking the work after it has been brought into the field is troublesome and requires manpower. In particular, recently, automated machines such as auto clamps and auto claws have been introduced at construction sites as well, and the rapidness of unpacking work is required to increase the operating rate of these machines.

The present invention solves the above problems, and an object thereof is to lift a load while correcting a load shift of the load without restraining a plurality of load by a fixing means. It provides a lifting device for materials that can be unloaded quickly at a position.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a pallet in which a vertical frame and a horizontal frame are combined in a rectangular shape, and a suspension ring having one end locked at both ends of each horizontal frame and a suspension ring provided at the other end. A hanging jig made of a belt and a steel material having a length equal to the distance between the horizontal frames, and provided with a hanging wire locking portion at both ends of the steel material and a pair of hooks for locking the hanging ring on both sides of the locking portion. And with.

[0006]

[Action]

 According to the above configuration, when a plurality of suspended loads are loaded on the pallet and the suspension rings of the belts are locked to the hooks at both ends of the suspension jig, the suspension is ready for suspension.

If the hanging jig is lifted through the hanging wire in this state, each belt is tensioned and presses the side surface of the hanging load to be in a so-called belt lashing state, which is a case where the belt is in a piled state. Corrects the suspended load to the correct packaging and restrains the surroundings.

When the pallet is installed at the carrying position and the tension of the belt is released, the unloading is completed by removing the hanging ring from the hook.

[0009]

【Example】

 An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows a material lifting apparatus according to the present invention, which includes a pallet 1 formed in a vertically long rectangular frame shape, four lifting belts 2 having one end fixed to four corners of the pallet 1, and a lifting tool. It is composed of a tool 3.

The pallet 1 is composed of a pair of vertical frames 1a arranged in parallel, a pair of horizontal frames 1b which are also arranged in a line orthogonal to the vertical frame 1a, and a reinforcing member which is surrounded by these and obliquely arranged inside. It consists of 1c. Although not shown, if a girder material is fixed to the lower part of the pallet 1 to form a gap that can be lifted by a forklift, it can be adapted to a transfer work by a fork or the like.

A rubber plate 4 for cushion is arranged on the upper surface of each horizontal frame 1b. A pair of brackets 5 are fixed to both ends of each horizontal frame 1b by welding or the like, and each bracket 5 is provided with a shaft 6 that connects the base ends of the suspension belts 2 in a loop.

The hanging belts 2 are all formed to have the same length, and a hanging ring 7 that is detachably connected to the hanging jig 3 is fixed to the free end side.

The hanging jig 3 is made by welding a hanging wire locking portion 10 having locking holes 9 at both ends of an H-shaped steel 8 having a length equal to the length between the horizontal frames 1b. A pair of hooks 11 are integrally provided on both sides of the. A retaining metal 11a is tiltably attached to the inner circumference of each hook 11. Further, both ends of the suspension wire 12 suspended from the crane hook F 1 are connected to the locking portion 10 in an annular shape.

In the above-described configuration, for example, as shown in FIG. 2A, when the short floors 14 are stacked and suspended as three loads on the pallet 1 at the transfer standby position, 2B, first, the hanging jig 3 is positioned on the uppermost short floor 14, and then the hanging belt 2 is turned up, as shown in FIG. 2B. The suspension ring 7 is locked to the hook 11.

Next, when the hanging wire 12 is slung on the crane hook F and the hoisting operation is performed, the belt 2 is pulled up, and a tension force in the direction of the arrow to form a triangle is created between the belt 2 and the hanging jig 3, and this belt rush causes As a result of pressing each short floor 14 toward the center side of the pallet 3, as shown in FIG. 2 (c), the short floors 14 are rectified in an orderly stacked state, and the safety at the time of lifting is improved. Reserved. In this state, each slab 14 is lifted in the air while being restrained by the suspension belts 2 on both sides, so that each slab 14 is safely transported to the intended loading position and lands there.

After landing, the unloading work is completed immediately by removing the suspension ring 7 from the hook 11. The suspending jig 3 may be common to each pallet 1, and the pallet 1 on which the short floor 14 is placed may be reciprocated to the transfer standby position again with the loading position, or the pallet in an empty state. It is also possible to suspend 1 and return to the transport standby position.

[Effect of device]

 As described above in detail with reference to the embodiments, in the material hoisting device according to the present invention, a plurality of hoisting loads are loaded on the pallet, and the hook ring of each belt is engaged with the hooks at both ends of the hoisting jig. When stopped, the machine is ready for hoisting, and when the hoisting jig is hoisted, each belt becomes tense and presses the side of the hoisted load into what is called a belt lashing state. Since the suspended loads are corrected to the correct packaging and restrained, multiple suspended loads can be safely transported without the need for binding means.

Further, when the pallet is installed at the transport position and the tension of the belt is released, the unloading can be completed by removing the suspension ring from the hook, so that there is an advantage that the unloading work can be performed quickly.
