BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple installation type winch, for example, tow an electric wire along the upper surface of a ladder type electric line formed in a ship or a building, or tow a heavy object in a narrow space in a ship. The present invention relates to a simple installation type winch that can be easily installed at a desired position when performing the operation.

In addition to electric wires, it can be applied to pulling long objects such as pipes and optical fiber cables.

[0003]

2. Description of the Related Art For example, a winch of a fixed floor type has been conventionally used for towing an electric wire or towing a heavy object when laying an electric wire in a ship or the like.

An example of this will be explained by taking an electric wire laying operation as an example. FIG. 8 shows a fixed floor type winch 30, which has an air motor 32 and a winding drum 31 driven by the air motor 32. It is fixed to the floor surface 25 (see FIG. 7) by a mounting bolt that penetrates the mounting hole 34.
Reference numeral 33 in FIG. 8 indicates an operating lever of the air motor 32.

Then, as shown in FIG. 7, a ladder-type electric circuit
The electric wire 11 installed on the floor 25 near the lower end of the electric wire 20 and wound in the electric path 20 is wound around the winding drum 31 via the rope 28, so that the electric wire 11 is pulled to the upper surface of the electric path 20. The electric wire 11 is laid. In FIG. 7, reference numeral 26 is a floor roller, reference numeral 27 is a roller attached to the terminal end of the electric path 20, reference numeral A is a worker, and reference numeral B is a watchman. An electric winch 35 as shown in FIG. 9 may be used as the floor-fixed winch, but when the electric winch 35 is used, the electric wire pulling operation is performed by the same operation as the air motor winch described above. Is performed. Reference numeral 36 in FIG. 9 is a winding drum, and reference numeral 37.
Is an electric motor, reference numeral 38 is an operation switch, and reference numeral 39 is an installation hole.

[0006]

By the way, in the conventional electric wire laying work as described above, the rope 28 connected to the end of the electric wire 11 is passed through the roller 27 and the floor roller 26, and then the winch 30.
The rope 28 and the electric wire 11 are wound around the take-up drum 31 of FIG. 1 and operated by the operator A. In this work, the winch 30 is installed on the floor surface, and therefore the movement path of the rope 28 and the electric wire 11 is concerned. Becomes longer, so worker A
Therefore, it is difficult to accurately grasp the movement status of the electric wire and the tension status of the rope 28.

Therefore, the watchman B is required for safety, and the worker A starts and stops the winch based on the signal from the watchman B.

As a result, there is a problem that two workers are always required, and if the worker A and the watchman B do not breathe properly, the work becomes dangerous and difficult.

Further, it is difficult to fix the winch itself to the floor surface, and it is necessary to install a plurality of rollers, and further, the width of the electric line and the interval of the electric line hangers are variously changed, and the ceiling is also different. Due to changes in the height of the surface, changes in the condition of the floor, etc., it takes a lot of time to install winches and rollers, and it takes a long time to prepare for the work. Further, there is a problem that a strong winch is required due to an increase in resistance due to a plurality of rollers, which leads to an increase in size of a winch to be used. The present invention is intended to solve such a problem, and pulls an electric wire or the like. It is an object of the present invention to provide a simple installation type winch that can be easily installed in an optimum place according to the situation and can be operated by one worker.

[0010]

In order to achieve the above-mentioned object, a simple installation type winch of the present invention comprises a prime mover, a winding drum driven by the prime mover, and an engaging portion for a towed object at a tip portion thereof. And a winding wire wound around the winding drum, wherein the prime mover and the winding drum are mounted inside a main body formed of a hollow cylinder, and the one side end of the main body The take-up wire is led out, and a holding wire for attaching the main body to a fixed object is attached to the other end of the main body.

[0011]

In the above-described simple installation type winch of the present invention, when the winding wire is wound on the winding drum, the towed object engaged with the tip end portion of the winding wire is pulled.

On the other hand, since the main body of the winch is fixed to the fixed object via the holding wire, tension is generated in the holding wire when the winding wire is pulled, and the winch is predetermined by the winding wire and the holding wire. The action of holding in position is performed.
