BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire drawing tool and a trolley capable of supporting a steel wire such as a steel stranded wire and extending the wire and also serving as a trolley to be transported to an appropriate place. .

[0002]

2. Description of the Related Art Stranded steel wires have excellent strength, but due to the characteristics of steel wires, there are some problems in handling such as splashing at the time of cutting or handling of drawn wires and collapse of the drum.
In consideration of the repulsive force and the like due to the rigidity of the steel stranded wire, various wire pedestals for the steel stranded wire have been considered. These are made by winding steel strands around a drum supported on a base, braking the rotation of this drum, while inserting one end of the steel strands wound from this drum in the unwinding direction and in the opposite direction. It is stopped by passing it through a steel wire fitting that can be stopped.

[0003]

However, in order to mount the drum having the steel strands wound around the outer periphery on these wire reels or carriages, the operator lifts these drums and fits them on a vertical support shaft. Since it has to be mounted on a horizontal shaft and the drum around which these steel strands are wound is quite heavy and requires a lot of labor, at least two workers are required.

This invention was made in view of the above points, and a drum around which a steel wire such as a heavy steel twisted wire is wound can be mounted on a carriage very easily by one worker. Also, it is easy to carry, and provides a wire drawing tool / carriage that can reliably brake the rotation of the drum and grip the steel wire even when the steel wire is transported or drawn against the repulsive force due to the rigidity of the steel wire. By doing so, the above problem is solved.

[0005]

In order to solve the problems, the invention of claim 1 is arranged such that a drum around which a steel wire is wound is rotatably passed through a shaft provided with a brake device on one side, and the shaft on the other side of the drum is further passed through. , The brake device and the drum are abutted against each other to be detachably fixed through a collar that stops the movement in the axial direction,
A projecting arm that can be engaged with a nut projecting to the outer surface of the flange of the drum is provided so as to project from the brake wheel of the brake device.

On the other hand, a support body composed of a frame-like frame is provided, and bearings having grooves on the upper edges are provided on both sides of one end of the support body, and the drum, the brake drum and the collar are mounted in the grooves of these bearings. Both ends of the shaft are inserted so that the shaft is rotatably supported by these bearings. Further, one end of a brake rod is supported on the side of the support opposite to the bearing so that the length thereof can be adjusted, and the other end of the brake rod is connected to the brake device. A brake wire may be used for this brake rod.

[0007] Further, a steel wire threading metal fitting through which one end of the steel wire of the drum is inserted, which can be inserted in the feeding direction and which can be locked in the opposite direction, is slidably and rotatably provided on the support.
A wheel that supports the support is provided below both ends of the support having the bearings. According to the invention of claim 2, in the above structure, the other end of the support is provided with an extendable handle.

According to a third aspect of the present invention, in the above construction, the steel wire threading fitting is provided with a tapered hole on one side of the tubular main body, the tapered bore of which gradually becomes narrower toward one end surface of the tubular main body. A tube body is provided that slidably penetrates both end surfaces of the tubular body through the tapered hole, and between the flange fixed to the outer periphery of the tube body and one end surface of the tubular body opposite to the tapered hole. Provided on the outer circumference of the tube is a spring spring biased to push the brim into the taper hole, and in the taper hole, a ball whose one side can be fitted into a long hole drilled at an appropriate location on the outer circumference of the tube. It is configured to be inserted freely.

[0009]

In order to mount the drum around which the steel wire is wound on the carriage, the shaft having the brake device fixed to one side is passed through the drum, and the collar is mounted to the shaft on the opposite side of the drum. . At this time, the brake device and the drum are brought into contact with each other to stop their axial movement. In this way, the shaft is horizontally passed through the drum, and the drum is placed on the ground or floor in this state.

Then, the worker carries the trolley to the drum portion, puts one end of the support having wheels on the side of the drum, tilts the support so that the support is erected, and the shafts protruding from both sides of the drum are attached. Fit the shaft of the drum into the groove of each bearing by scooping with the bearings on both ends of the support. As a result, the shaft of the drum is rotatably supported by the bearings of the support.

Further, the other end of the brake rod connected to the brake device is supported by a support body such that its length can be adjusted. As a result, if the length of the brake rod is adjusted to be short, the braking force of the brake device will be large. Therefore, adjust the length of the brake rod so that the drum does not rotate. Then, one end of the steel wire wound around the drum is passed through the steel wire fitting.

As a result, when the drum is about to rotate,
The nut protruding from the outer surface of the flange of the drum hits the protruding arm protruding from the adjacent brake device, and the rotation of the brake wheel is suppressed by the tension of the brake rod, so that the rotation of the drum is also suppressed. By adjusting the tension of the brake rod in this manner, rotation braking of the brake wheel and the drum that is locked and integrated with the brake wheel is performed. Further, one end of the steel wire wound around the drum is held by the steel wire threading fitting. When the extendable handle is provided at the other end of the support according to the second aspect, an operator can extend the handle and use it when transporting the support.

Further, in the steel wire threading fitting according to the third aspect of the present invention, when the steel wire is passed through the pipe body and the steel wire is pulled in the unwinding direction of the steel wire of the drum, the pipe is pulled from the long hole of the pipe body. Each ball whose one side protrudes into the body rotates due to the sliding of the steel wire, and each ball moves to the large diameter side in the tapered hole by pushing the flange of the outer circumference of the tube against the force of the spring spring. Therefore, each ball slightly floats from the elongated hole formed on the outer circumference of the tube. Therefore, the steel wire slides smoothly inside the pipe.

On the other hand, when the steel wire passed through the tubular body of the steel wire passing fitting is pulled in the winding direction of the steel wire around the drum, the balls partially contacted with the outer periphery of the steel wire through the elongated hole of the tubular body are made of this steel. It rotates by sliding the wire and moves inside the tapered hole to the smaller diameter side. At that time, the flange of the tube guides the movement of the ball by the force of the spring. The other side of the ball, which is in contact with one side of the tapered hole, gradually enters deep into the elongated hole of the tubular body and presses the outer circumference of the steel wire. As a result, the outer circumference of the steel wire is pressed by a plurality of balls, and movement of the steel wire is blocked.
