DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winch device for winding and feeding a linear body such as a rope and a wire by a single drum.

[0002]

2. Description of the Related Art Conventionally, as a tow of a heavy object, as shown in FIG. 4, the end of a linear body is wound around one drum in a different winding direction, and the linear body is wound by rotating the drum. ,
A winch device that performs feeding simultaneously is known, but in such a device, when winding and feeding, the winding directions of the respective wire members are different, so that the wire members interfere with each other, and the wire members are twisted or wound. And the linear body was easily damaged. Conventionally, as shown in FIG. 4, a mechanism for applying tension to the linear body is separately provided outside the winch device, so that the structure is complicated and maintenance is difficult. In addition, as this type of winch device, there is

Are disclosed.

[0003]

The problem to be solved by the present invention is to solve the above-mentioned problems, to eliminate the interference between the winding and feeding linear members, to prevent the linear members from being damaged, and to prevent the linear members from being damaged. It is an object of the present invention to provide a winch device capable of smoothly performing a body operation and a winch operation, and further having a linear tensioner pulley built into the device to realize a simplified operation system.

[0004]

Means for Solving the Problems The structure of the present invention which has solved the above problems is as follows: 1) A linear body such as a wire rope is wound on one drum winding drum surface.
The outer periphery of the drum is composed of a surface so that
And a take-up part and an extension part in the middle of the drum winding drum surface.
And a partition wall that separates
It is rotatable in parallel with the drum and urges in the tension direction of the linear body.
And a linear body is formed from the winding section and the feeding section of the drum.
Pull it out, wind it around the tension pulley,
Endless connection of the linear material that is fed out and wound from the outside
Urging the winch device 2) tension pulley, wherein the tension direction of the linear body
The tension pulley is supported by a torsion spring as a means.
The winch device according to the above 1) .

[0005]

In the winch device according to the present invention, both ends of the linear body having the load attached to the winding drum surface portion sandwiching the intermediate partition wall of the drum are wound in a fixed number of turns by changing the winding directions with respect to each other. When the motor of the winch device is operated, the drum rotates, and the linear body is wound and fed simultaneously at the two winding drum surface portions, and the load is towed and moved. Since the winding and unwinding are performed at separate portions divided by the partition wall, no interference of the linear body occurs.

In a configuration in which a tensioner pulley of a linear body is provided in a winch device, the linear body is endless, and the linear body is hung on a tensioner pulley located between a winding side and an unwinding side to connect both sides. Since the tension of the linear body is maintained inside the winch device, there is no need to separately provide a tension mechanism for the linear body outside.

In a configuration using a torsion spring as a biasing means for the tensioner pulley, both ends of the fixed torsion spring are
The urging force is the force of the torsion spring coil portion passing through the rotating shaft drawn to the drum side to return, and a reliable tension of the linear body can be obtained with a compact configuration.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described with reference to the following drawings. This embodiment is an embodiment of a winch device provided with a tensioner pulley urged by a torsion spring in the device. FIG.
Is an explanatory diagram showing an operating system using the winch device of the embodiment,
FIG. 2 is a side view showing a main part of the embodiment, and FIG.
FIG. 4 is an explanatory view showing an operation system using a conventional winch device. The winch device 1 of this embodiment is a rope 1
The winding drum surface 3 of the drum 2 around which 1 is wound is divided into two by a partition wall 4. Below the drum 2 is a tensioner pulley 5 attached to a rotating shaft 6 slidably supported by a bed 9 up and down. The tensioner pulley 5 is located just below the partition wall 4 to provide tension to the rope 11. On both sides of the rotating shaft 6 of the tensioner pulley 5, torsion springs 7, which have different winding directions,
8 are respectively extrapolated, and both ends of the torsion springs 7 and 8 pulled upward together with the tensioner pulley 5 and the rotating shaft 6 by the rope 11 are held by spring supporting portions 9a of the bed 9, and the torsion springs 7 are held. , 8 generate a force to return to the original state, which is used as the urging force of the tensioner pulley 5. A motor 10 with a speed reducer for rotating the drum 2 is provided on the side of the drum 2. The rope 11 is wound around the two winding drum surfaces 3 of the drum 2 after the tension is adjusted by the tensioner pulley 5, and extends therefrom to support the load 12 and is endless in shape. ing. In the method of use of the present embodiment, the motor 10 with the speed reducer is rotated forward and reverse in accordance with the direction in which the load 12 is towed, and the rope 11 is wound and fed to move. Since the tension of the rope 11 is automatically adjusted by the biased tensioner pulley 5 in the winch device 1, there is no need to provide an external adjusting means.

[0009]

According to the present invention, by employing the above-described structure, the winding portion and the feeding portion of the linear body are separated on the drum to prevent interference, so that the linear body is twisted or irregularly wound. Winding and unwinding work can be performed without causing any damage, and the service life of the linear body can be extended, and winch work can be performed smoothly, and workability is good.

If a structure in which a tensioner pulley is provided in the apparatus is employed, there is no need to provide a linear body tension adjusting mechanism externally, so that the entire operation system can be made simple and advantageous in terms of cost and maintenance. Becomes

In the configuration using a torsion spring as the urging means of the tensioner pulley, the linear tensioning is automatically adjusted with a simple and compact configuration, so that the entire winch device can be made compact and can be installed and installed. easy.
