Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire drawing vehicle capable of automatically passing through a tow clamp attached to an electric wire to be drawn and a rigid body portion such as a protector used as a protective cover thereof.

[0002]

2. Description of the Related Art As a conventional rigid body automatic passage type drawing vehicle, for example, JP-A-4-91605 and JP-A-4-916.
No. 06 etc. are known. These rigid body automatic passage type extension vehicles are capable of passing the rigid body portion while supporting the rigid body portion by means of a passage support attached to the shoe chain. There is. As a result, although the wire drawing work can be greatly streamlined, there is a problem that the wire drawing vehicle becomes considerably heavier and larger than the conventional one.

For example, as shown in FIGS. 5 and 6, the rigid body automatic passage type extended wheel vehicle disclosed in Japanese Patent Laid-Open No. 4-91606 is provided with an attaching / detaching device 50. The supporting members 51c and 51w are automatically attached to the shoe chain 53 of the shoe chain drum 52 in a predetermined relationship, and the rigid portion is supported by the pair of passing supporting members 51c and 51w attached to the shoe chain 53. It is designed to allow the passage of.

The attachment / detachment device 50 has four attachment / detachment hands (attachment / detachment means) 54 (54a, 54) corresponding to the provision of two to four passage supporters 51c, 51w, 51c, 51w.
b, 54c, 54d). Each detachable hand 54 is directly equipped with a hydraulic cylinder 54p, and each hydraulic cylinder 54p is configured to independently perform a back-and-forth movement as indicated by arrow Y. The individual pieces can be integrally moved by a slide mechanism 56 such as a feed screw as shown by an arrow X. That is, the removable hand 50
Normally, the positioning is performed with the reference position S as the end, but when performing the attachment / detachment work, the X position is used to selectively position the mounting position A and the removal position B, and the Y motion is used to position each position. In A and B, while advancing and retreating with respect to the shoe chain drum 52, the passage support tools 51 held by the shoe chain drum 52 are attached to and detached from the shoe chain 53.

As described above, the rigid body automatic passage type rolling stock is
Since a passage support and an attachment / detachment device for attaching / detaching it are added, it is unavoidable that the weight will increase and the size will increase to some extent as compared with the conventional wire drawing vehicle, but the extent of increase in size is a problem. Becomes In this regard, in the above-mentioned rigid body automatic passage type extended vehicle, the detachable hand is directly moved back and forth by the hydraulic cylinder, but this is largely related to the increase in weight and the increase in size. There is. That is, since the hydraulic cylinder is used in a direct connection type, a space corresponding to the length of the hydraulic cylinder itself is required as a space for moving the detachable hand back and forth in addition to the space for the back and forth stroke. Therefore, the weight is increased and the size is increased because a guide mechanism for moving back and forth is complicated and has high precision.

[0006]

SUMMARY OF THE INVENTION The present invention has been made against such a background, and an object of the present invention is to reduce the size and weight of a rigid body automatic passage type wire drawing vehicle.

[0007]

To achieve the above object, in the present invention, in order to pass a continuous linear body to which an electric wire is connected via rigid bodies at both ends thereof, the rigid body, Along with at least one pair of passage support tools for supporting the rigid body, which are paired for the wire side and for the wire side,
Each passing support is equipped with a detachable hand for automatically attaching and detaching these passing supports to and from the shoe chain. Mounted on and removed from the shoe chain while the forward / backward movement unit moves the shoe chain drum forward and backward while it is positioned at a predetermined position in the direction. In a rigid body automatic passage type extended vehicle that allows a rigid body portion to pass through while being supported by a passage support device, a left-right movement unit including a moving plate configured to move in the left-right direction by a sliding means. One end is rotatably connected to the detachable hand and the other end is rotatably connected to the moving plate so as to be parallel to each other. A number of parallel link members and a telescopic actuator rotatably supported by the moving plate and having a tip rotatably connected to an intermediate portion of one of the parallel link members. Accordingly, a forward / backward movement unit is provided in which each parallel link member is moved around the connection portion to the moving plate as a fulcrum to move the detachable hand back and forth.

[0008]

As described above, as a result of changing the expansion / contraction motion of the expansion / contraction actuator such as a hydraulic cylinder to the forward / backward movement of the detachable hand via the parallel link member, the operation mechanism such as the expansion / contraction actuator or the parallel link member. The member can be stored in an empty space in the height direction, and as a space in the length direction for allowing the detachable hand to move back and forth, only the space for the stroke of the detachable hand is sufficient.
The overall length can be shortened and the weight can be reduced as compared with the conventional structure which requires a space corresponding to the length of the hydraulic cylinder itself.

[0009]

EXAMPLES Examples of the present invention will be described below. In the following description, the parts common to the above-described conventional wire drawing vehicle are not shown and described, and the attachment / detachment device and the passage support, which are the main parts of the present invention, are mainly described. .

As shown in FIGS. 1 and 2, the attachment / detachment device 1 includes two to four passage support members 2 (2c, 2w) and an attachment / detachment hand 3 for each passage support member 2. ing. Here, the reason why the pair of passing support members 2 is two is that the two protectors simultaneously pass through the shoe chain drum in relation to the length of the split wire interposed between the electric wires connected in series. This is to deal with the situation.

As shown in FIG. 3, each attachment / detachment hand 3 has a pair of holding plates which are opened and closed by facing each other as indicated by an arrow Z by an opening / closing drive means 4 having a feed screw structure provided at the base end. 5, a holding portion 6 for holding the passage support tool 2 is formed at the tip of the holding plate 5.

Further, a back-and-forth moving unit 7 is provided corresponding to each attaching / detaching hand 3, and each of the back-and-forth moving units 7 can independently perform a movement as shown by an arrow Y, and four units. Attaching / detaching hand 3 moves left / right unit 8
Thus, the movement as shown by the arrow X (FIG. 2) can be integrally performed.

The forward / backward movement unit 7 includes four parallel link members 10 and a hydraulic expansion / contraction actuator, that is, a hydraulic cylinder 11.
Has become The four parallel link members 10 have one end rotatably connected to the detachable hand 3 so as to be parallel to each other and the other end by a bearing portion 13 provided on a moving plate 12 of a left-right movement unit 8 described later. It is rotatably supported. On the other hand, in the hydraulic cylinder 11, an intermediate portion thereof is rotatably supported by the moving plate 12 and the tip of the piston rod 11L has two front parallel link members 1.
It is rotatably connected to the middle portion of 0. Therefore, when the hydraulic cylinder 11 expands and contracts, the parallel link members 10 correspondingly rotate about the bearing 13 as a fulcrum while keeping the parallel state, and the detachable hand 3 moves back and forth. Become.

The forward / backward moving unit 7 having a structure using such a parallel link mechanism is the attaching / detaching device 5 shown in FIGS.
When the attachment / detachment device 1 is installed at the same position as 0, its mechanical member can be accommodated in an empty space in the height direction (the lower side of the attachment / detachment device 50 in FIG. 6), and the attachment / detachment hand 3 moves back and forth. As the space in the longitudinal direction for performing the above-mentioned operation, only the space for the forward / backward movement stroke of the detachable hand 3 is sufficient, which leads to shortening of the total length of the wire drawing vehicle and weight reduction.

The left-right moving unit 8 includes a moving plate 12,
It comprises a slide means 14, a pair of guide bodies 15 provided so as to sandwich the slide means 14, and a base plate 16 for fixing these in a predetermined arrangement.

A feed screw mechanism is used for the slide means 14, and the moving plate 12 is moved in the X direction together with the female screw member 18 attached to the lower surface thereof in accordance with the rotational driving of the male screw member 17 fixed to the base plate 16. I am supposed to do it.

Each guide body 15 includes a guide receiving member 19 attached to the lower surface of the moving plate 12 and the base plate 1.
6, a rail member 20 is fixed to the guide member 6, and the guide receiving member 19 receives a sliding guide by the rail member 20 when the moving plate 12 moves in the X direction.

The attaching / detaching hand 3 capable of the X movement and the Y movement as described above is normally positioned with the reference position S shown in FIG. 5 as an end. The X-movement selectively positions the mounting position A and the removal position B, and the Y-movement advances and retracts with respect to the shoe chain drum 52 at each of the positions A and B, while passing the support 2 (2c, 2c).
Perform the attaching / detaching operation of w).

Here, the mounting position A is a portion where the passing support 2 is mounted on the shoe chain 53, and corresponds to the wire-entry side of the shoe chain drum 52. Specifically, in FIG. The second roll from the bottom corresponds to that. Further, the removal position B is a portion where the passage support tool 2 is removed from the shoe chain 53, and corresponds to the wire outlet side of the shoe chain drum 52. Specifically, the second winding from the upper end in FIG. Applicable

As shown in FIG. 4, the pair of passage support members 2c and 2w have the same shape, and are mounted on the shoe chain 53 only by changing their directions. Incidentally, this figure shows a case where the protector P on the tip side of the electric wire C is supported, and the shoe chain drum 52
The electric wire C is on the inlet side (left side in the figure) of the and the split wire W is on the outlet side (right side in the figure).

The above-described embodiment is an example in which the specifications can be applied even when two protectors pass through the shoe chain drum at the same time. Therefore, two pairs of pass-through support tools and corresponding pairs are provided. The structure is equipped with 4 attachment / detachment hands and a mechanism attached to it, but if the specifications are such that only one pass protector is required, the weight of the entire pass can be reduced by using a pair of pass supports. Try to
