Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cable pulling machine that can easily center a long body, and more specifically, the present invention relates to a cable pulling machine that can easily center a long body. This invention relates to a centering device for a long object take-up machine that can center the long object with a simple operation by opening and closing the interval between the long object traveling paths.

Conventionally, long object pulling machines used to pull long objects such as ropes and cables use a pair of endless track bands that open and close vertically to prevent excessive force from being applied to the endless track band. He held the body in his arms and tried to take it away.

However, such a pulling machine equipped with a vertical open/close endless track belt has the disadvantage that it is difficult to attach and detach the elongated body, resulting in poor workability and difficulty in handling.

On the other hand, in the case of a pulling machine equipped with a horizontally opening/closing endless track belt, the contact point between the long body and the endless track belt changes depending on the diameter of the long body, and unreasonable force is applied to the endless track belt. As a result, the track belt may stretch or come off one side, which poses a practical problem.

For this reason, a method has been proposed in which the distance between the under roller and the pair of side rollers is adjusted by moving a frame equipped with an under roller that is slidably fitted into the inclined guide rod. Since the assembly is formed by moving the assembly, there are problems in that the assembly accuracy is poor and the levelness is also poor, making it difficult to move smoothly and making adjustment work difficult.

The present invention has been made in view of the above-mentioned conventional circumstances, and the present invention has been made by adjusting the size of a long body traveling path formed by a pair of endless track belts and a guide roller by adjusting the movement of a movable frame and the movement of a guide plate. The object of the present invention is to provide a centering device for a long body take-up machine that can center a long body by adjusting the sliding motion.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

In FIGS. 1 to 3 showing one embodiment of the present invention, numeral 1 denotes a long object take-up machine, and a stationary body equipped with a pair of endless track bands 2, 2 disposed with running surfaces 2a facing each other.

The feed device 17 has a feed shaft 19 rotatably supported by bearings 18, 18 provided at both ends of the base 2, and a feed base 20 screwed onto the feed shaft 19 between the bearings 18, 18, which is attached to a movable frame. A feed handle 2 fixed to the lower surface of 4 and provided at the end of the feed shaft 19
By rotating the frame 1, the movable frame 4 reciprocates left and right on the base 2.

Further, the guide plate 7 is formed in a substantially concave shape, and has a vertically elongated hole 7a at the end on the side of the movable frame 4.
However, two parallel inclined holes 7b are formed at the side end of the fixed frame 3, and the fixed frame 3
Two guide pins 8 protruding from the movable frame 4 and one guide pin 8 protruding from the movable frame 4 are slidably fitted into the inclined elongated hole 7b and the vertical elongated hole 7a, respectively.
It is designed to move up and down as the movable frame 4 moves.

The inclined elongated hole 7b has a 1/2 slope (≒26.5°) so that the movable frame 4 moves up and down by 1/2 of the horizontal movement.
It is formed on the slope of

Further, the guide pin 8 has a screw portion formed at its tip that is screwed into both the frames 3 and 4, and a head 8a is formed at the end that engages with both the elongated holes 7a and 7b. , 7b is designed to prevent the guide plate 7 from coming off.

Further, the guide roller 6 has an upper end of its outer peripheral surface projecting upwardly from the upper end of the guide plate 7, and is provided at the center of the upper part of the guide plate 7 so as to be freely rotatable in the horizontal direction.

Next, its effect will be explained.

First, after passing a long object such as a rope or cable through the long object running path P formed between the pair of endless track bands 2, 2, the feed handle 21 is rotated to move the movable frame 4 left and right. It moves, adjusts the size of the traveling path P, and sandwiches the elongated body between the endless track bands 2, 2.

At this time, as the movable frame 4 moves from side to side,
The guide plate 7 is guided by both elongated holes 7a and 7b and moves across the movable frame 4 (moves up and down), and the guide roller 6 provided on the guide plate 7 also moves up and down, so that the lower surface of the elongated body They come into contact with each other and sandwich the elongated body together with the pair of endless track bands 2, 2.

In this case, when the movable frame 4 is moved left and right by a distance d, since the inclined elongated hole 7b has a 1/2 slope, the guide roller 6 moves upward by d/2, and the elongated body is moved to the center of the traveling path. hold in position.

It should be noted that even if the guide plate 7 has a vertically elongated hole 7a on the fixed frame 3 side and an inclined elongated hole 7b on the movable frame 4 side, contrary to the above embodiment, it will have the same effect as in the above embodiment. be able to.

Furthermore, the fixed frame 3 may be used as a movable frame, and the movable frame 4 may be used as a fixed frame.

As explained above, in the centering device according to the present invention, a pair of endless track bodies are arranged relative to each other with their running surfaces facing each other, each supported via a fixed frame and a movable frame.
These fixed frames and movable frames are provided on a base, and the movement of the movable frame with respect to the fixed frame allows a long body traveling path formed between a pair of endless track bodies to be opened and closed in the horizontal direction. In the long body pulling machine, a guide plate facing the ends of the fixed frame and the movable frame is disposed at the end of the long body traveling path in the longitudinal direction, and the guide plate is provided with a guide plate facing the ends of the long body traveling path. A guide roller is attached that intersects with the guide plate, and the end portions of the above-mentioned frames are connected to each other by moving the guide roller in a direction intersecting with the elongated body traveling path due to the movement of the movable frame. In order to adjust the width of the passage, these two frame ends are engaged with each other through a guide pin formed relative to the guide plate, a vertical elongated hole, and a plurality of oblique elongated holes having a 1/2 slope. It is characterized in that the guide plate is slidably supported by both frames.

The centering device of the present invention having such a configuration can adjust the size of the elongated object traveling path by moving the movable frame left and right by simply rotating the feed handle and moving the guide rollers up and down in conjunction with each other.

Therefore, regardless of the diameter of the elongate body, the elongate body can always be accurately and easily positioned and held in the center of the elongate body travel path.

Moreover, since it is sandwiched between the pair of endless track belts and the guide roller, deformation and damage such as twisting and bending during the take-up operation is less likely to occur, and unreasonable force is not applied to the endless track belt. , it is possible to obtain strong pulling power.

Further, the endless track belt can be of a type that opens and closes in a non-vertical direction, and in this case, the elongated body can be easily attached and detached, and the space required is small, so that work efficiency is improved.
