Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hanging device in a lifting and transporting device.

Most conventional devices for lifting objects independently operate a hook or other hanging device.
Therefore, when an object to be transported is suspended at multiple locations due to its shape or other characteristics and transported horizontally, each hook is operated independently to hang the object. Therefore, the hanging work was time-consuming and required at least two workers.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to enable two hooking tools to be moved by one operation, thereby speeding up and simplifying the hanging work and saving labor.

The present invention achieves the above object by movably disposing two carts each having a hook on the frame, and imparting elastic pulling force to each cart to draw it toward the end of the frame, while also allowing the carts to move freely relative to the frame. A handle is provided on the handle, a pulley is provided on the handle,
The hanging device consists of connecting each end of a cable to the opposing ends of each truck, and winding the cable around a pulley on the handle via a pulley provided approximately at the center of the frame.

EMBODIMENT OF THE INVENTION Hereinafter, one Example of the hanging device based on this invention is demonstrated based on drawing.

FIG. 1 shows a schematic perspective view of a hanging device according to an embodiment, FIG. 2 shows the front, FIG. 3 shows a plan view, FIG. are shown on each side.

The frame 1 is composed of two guide frame members 2a, 2b made of channel steel or the like that face each other, and coupling frame members 3a, 3b that connect both ends of the guide frame members 2a, 2b. Two hook carts 4a, 4b are mounted between the guide frame members 2a, 2b via attached wheels, and are slidable in the longitudinal direction of the guide frame members 2a, 2b. Hook trolley 4
Hooks 5a and 5 are placed on a and 4b facing each other.
b is installed. Wheels 6a and 6b are attached to the upper surface of the frame 1 at symmetrical positions with respect to its longitudinal center, and these wheels 6a and 6
b, the frame 1 is suspended from frame members 7a, 7b on the transport device side. frame 1
A horizontal member 8a and a vertical member 8b are provided on the side surface of one end.
An angular support arm 8 consisting of is stretched, and a handle 10 is provided on the vertical member 8b so as to be movable up and down while being guided by guide rollers 9. Reference numeral 11 denotes a grip portion provided on the handle 10.
An actuating pulley 12 is provided at the center of one side of the handle 10, and pulleys 13a and 13b are provided at the intersection of the horizontal member 8a and the vertical member 8b in the support arm 8 at different positions left and right and up and down. ing.
Further, near the joint portion of the support arm 8 with the frame 1, two independently rotatable pulleys 14a and 14b for changing direction are provided above and below.
A horizontal frame member 15 is passed between the guide frame members 2a and 2b in the longitudinal center of the frame 1, and the intersection of the horizontal frame member 15 and the guide frame member 2a has two independently rotatable directions. Pulleys 16a and 16b for changing are provided above and below. Also, near the center of the horizontal frame member 15, there are two central pulleys 1 that are rotatable independently.
7a and 17b are provided above and below. Automatic rewinding devices 18a, 18b using springs are provided on the joint frame members 3a, 3b at both ends of the frame 1, and the center of the outer end of each automatic rewinding device 18a, 18b and each hook truck 4a, 4b. part and wire 19
a, 19b are connected via pulleys 20a, 20b, and an elastic tensile force is always applied to the hook carts 4a, 4b in the direction of pulling them toward the end of the frame 1. Each end of a wire 21 as a cable is connected to the center of the inner end of the hook carts 4a, 4b, and the wire 21 is connected to the upper and lower center pulleys 17a, 17.
b from different sides, and pulley 1
6a, 16b, 14a, 14b, 13a, 13b
The actuating pulley 12 is wound around the handle 10 through the actuating pulley 12. Therefore, when the operator grasps the grip portion 11 and pulls down the handle 10, the operating pulley 1
2 pulls down the wire 21, and the two hook carts 4a, 4b move closer to each other toward the center of the frame 1. At this time, the wires 19a, 1
9b is pulled out from automatic rewind devices 18a and 18b. When the pull-down force of the handle 10 is released, the wires 19a, 19b are rewound by the unwinding force of the automatic unwinding devices 18a, 18b, and the hook carts 4a, 4b are pulled back to the frame 1 end on each side.

Next, the hanging operation of this hanging device is carried out in the sixth stage.
An explanation will be given by taking as an example the suspension of cabs on the truck assembly line shown in FIGS.

When the cab 22 sent on the conveyance line reaches a predetermined position, the hoisting device is lowered by the operation of the lifting device in the conveying device, and the hooks 5a and 5b are attached to the roof side portion 23 of the cab 22.
It descends until it is below a and 23b. At this time, the hook carts 4a and 4b are operated by the automatic rewinding device 18.
a and 18b, respectively, and are located at the rearward end (frame 1 end) (indicated by solid line A in FIG. 6).

Next, the operator grasps the grip portion 11 and presses the handle 10.
When pulled downward, the hook carts 4a and 4b move toward the center of the frame 1, and the hooks 5a and 5b touch the roof side portions 23a and 23b, as shown by the two-dot chain line B in FIG. Stop at.

In this state, when the lifting device of the transportation device is operated to raise the roof side portion 23, the hooks 5a and 5b move upward.
a, 23b, the hooks 5a, 5b are fixed by frictional force with the roof side portions 23a, 23b, making it possible to lift the cab 22 (indicated by two-dot chain line C in FIG. 6).

When lowering the cab 22 onto a truck or vehicle frame at another location, the hoisting device is lowered by the lifting device, and the cab 22 is further lowered from the position where it is placed on the truck or the like. Since the hooks 5a, 5b are located below the roof side parts 23a, 23b, the fixing force of the hooks 5a, 5b due to frictional force is eliminated, and the wires 19a, 19b are not wound by the rewinding action of the automatic rewinding devices 18a, 18b. The hooks 5a, 5b are returned to the side of the cap 22 together with the hook carts 4a, 4b.

Thereafter, the lifting device raises the hanging device, and the transportation device returns to its original position and waits.

This hanging device can cope with the case where the center of the hanging device and the center of the cab 22, which is the object to be transported, are misaligned. In other words, it has a self-aligning function. As shown in FIG. 7, if the center O ₂ of the cab 22 is offset from the center O ₁ of the hanging device, hold the hooks 5a and 5b below the roof side parts 23a and 23b. When the handle 10 is pulled down by holding the part 11, the two hook carts 4a and 4b move toward each other, but
As shown by the solid line in FIG. 7, while one hook 5a is in contact with the roof side portion 23a, the other hook 5b is still in a position away from the roof side portion 23b. When the handle 10 is further pulled down from this state, only the portion of the wire 21 that is still movable and connected to the hook truck 4b is pulled down, and the hook truck 4b moves and the hook 5b is moved to the roof side portion as shown by the two-dot chain line in FIG. It stops when it hits 23b. Thereafter, lifting and transportation is performed in the same manner as in the previous example.

In the above embodiment, the hook carts 4a, 4b are moved closer by lowering the handle 10, but by moving the handle 10 upward, laterally or in other directions, the hook carts 4a, 4b are moved closer to each other.
It is also possible to make b move toward each other. Moreover, hooks 5a, 5 provided on the hook carts 4a, 4b
One or more b are provided depending on the object to be transported.

As explained in detail based on one embodiment above,
According to the hanging device according to the present invention, since two hooks can be moved with one action of moving the handle, hanging work becomes easy.
In addition, since the hanging work can be carried out by one worker, labor can be saved. Furthermore, since the hanging device according to the present invention has a self-centering function, it can cope with the case where the center of the object to be transported is shifted from the center of the hanging device.
