B, a handle portion 2C protruding from the upper surface of the tubular side wall portion, and a roller supporting leg portion 2D protruding from the right side of the tubular side wall portion. Reference numeral 2E is a shackle mounting hole that is provided on the right side portion of the cylindrical side wall portion.

Reference numeral 3 denotes a wire drum portion which is rotatably fitted from a front opening portion of the case 2, and which is a pulley body 3A.
And a ring body 3B corresponding to the inner side of the cylindrical side wall portion 2B of the case 2 that is continuously provided on the back side of the pulley body, and an internal tooth 3C engraved on the inner surface of the ring body. The wire drum portion 3 and the wire drum portion 3 are connected by a central shaft 4. Reference numeral 5 denotes a rotary shaft that penetrates through a circular hole formed on the right side of the back surface 2A of the case 2, a gear 5A meshing with the internal teeth 3C is fixed to the tip of the rotary shaft, and a rear end is provided at the rear end. Gear 5B
The handle 5C is connected via. Therefore,
When the handle 5C is rotated, the wire drum part 3 is rotated.

On the left side of the cylindrical side wall portion 2B of the case 2, there is provided a wire inlet portion 6 for introducing a wire into the pulley body 3A of the wire drum portion. The wire entrance portion 6 is composed of upper and lower horizontal rollers 6A and 6A which are horizontal with respect to the wire traveling direction, and front and rear vertical rollers 6B and 6B which are located outside the upper and lower horizontal rollers. Of the front and rear vertical rollers 6B, 6B, the front vertical roller 6B is configured to be capable of undulating with the lower end as a fulcrum. The undulating structure is used in order to insert the wire 7 into the wire inlet portion 6 from the front side.

Referring to FIG. 2, the extension of the balance line 6A1 of the load orthogonal to the horizontal roller 6A is configured to pass through the center of the shackle mounting hole, and with reference to FIG. 4, the vertical roller 6B. An extension of the balance line 6B1 of the load orthogonal to is configured to pass through the center of the central axis 4 and the center of the shackle.

Referring to FIG. 5, reference numeral 8 is a structure for engaging and disengaging with the internal teeth 3C of the case 2 by operating vertically on the front surface of the cylindrical side wall portion 2B of the case 2 around the pin 8A. With the ratchet, the operating pin 8C configured to be constantly pulled upward by a spring is connected to the connecting pin 8B that is pulled out of the case from the ratchet through the long hole opened in the cylindrical side wall portion. There is. Therefore, when releasing the ratchet, this operation pin is pushed.

Reference numeral 9 denotes a wire feeding roller portion, and as described above, a shaft rotatably supported by a bearing provided on a roller supporting leg portion 2D projecting to the right of the cylindrical side wall portion 2B of the case 2. 9A, a feeding roller 9B attached to the tip of the shaft, and a gear 9C attached to the rear end of the shaft. The gear 9C and the gear 5B mesh with each other. The position of the feeding roller 9B is configured to correspond to the front and rear position of the pulley body 3A, and a wire guiding groove 9B1 is formed in the feeding roller.

Numeral 10 is a tension roller portion, which is a link 10A supported by a roller supporting leg portion 2D so as to be vertically movable, and a tension rotatably supported at the tip of this link so as to correspond to the lower surface of the feeding roller. Laura 1
0B, and a spring 10 that causes the link to always act upward.
It is composed of C and. The above was explained using wires,
The same is true for ropes.

The present invention operates as follows.
(See FIG. 6) 1. Between the base pillar 11 and the luggage 12 that is about to be pulled toward the base pillar, the base pillar and the wire locking portion 2E in the winch of the present invention are connected by the wire 13. 2. On the other hand, after the wire 7 connected to the luggage 12 penetrates through the wire inlet portion 6 and is wound around the wire drum portion 3 several times,
It is pulled out rearward through between the feeding roller 9B and the tension roller 10B. 7A is the rear end of the wire 7. 3. When the handle 5C is rotated, the luggage is pulled toward the base pillar.

The above description has been made in the case where the luggage is placed on the horizontal plane, but the same applies to the case where the luggage is to be pulled up on an iron pole, for example. It should be noted that a known electric drill or an impact wrench can be used instead of the handle to rotate the handle.

[0015]

Since the present invention is constructed as described above, it has the following effects. 1. The conventional type requires two workers, but the present invention can be used by one person for winding work. 2. In the past, when lifting things to high places, you would use a guide wire to separate your luggage from buildings, towers, etc.
Other tools for pulling were used on the ground fulcrum such as the guide wire, but it was not easy to pull at once because the length of the wire was short. However, in the case of the present application, since the wire itself can be wound as it is, it is possible to perform a safe operation.
