2. Description of the Related Art Conventionally, as a device for supporting a long body of this kind, as shown in FIGS.
Is provided in the vicinity of the position of the feeding portion 8.

[0003]

According to the above-described conventional device for supporting a long body, when one end of the long body 1 is pulled out through the feeding portion 8 as shown in FIG. 1 is pulled toward the feeding portion 8 side, and a part thereof assumes a posture indicated by a two-dot chain line in the figure. At this time, the elastic restoring force of the elongated body 1 acts in a direction to make the annular body K more strongly contact the lower peripheral support roller 3 as shown by an arrow in the figure, and the elongated body 1 As a result, the frictional force with the lower peripheral support roller 3 increases. As a result, there is a problem that extra resistance is applied to pull out the elongated body 1, a large pulling force is required, and it is not possible to smoothly pull out the elongated body 1.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problems and to provide a long-body support device capable of pulling out a long body with a small pulling force.

[0005]

In order to achieve this object, the present invention has a long-body supporting device which is characterized in that it has a plurality of portions at an outer peripheral portion of an annular body around which a flexible long body is wound. A plurality of outer peripheral support rollers that are separately abuttable and rotatably supported are mounted on a support frame with their rotation axes oriented in a direction along the axis of the annular body, and both end surfaces of the annular body are freely rotatable. A plurality of end surface supporting rollers, and an inner peripheral supporting roller that can be inscribed in the elongated body, with a rotation axis oriented in a direction along the axis, and a pair positioned radially below the annular body. Between the outer peripheral support rollers, in a long body support device provided with a payout portion that can feed out one end of the long body from the annular body, the inner peripheral support roller, the position of the feed portion On the other hand, at the place where it is located almost in the radially opposite part of the annular body That.

It is preferable that each of the end face supporting rollers is disposed on or substantially on radiation with respect to the axis.

[0007]

According to the characteristic structure of the long body supporting device of the present invention, as shown in the operation explanatory view of FIG. Since the one end of the elongated body 1 is pulled out through the feeding part 8 because the K is arranged almost in the radially opposed portion of K, the elongated body 1 is pulled toward the feeding part 8 side, and a part thereof is pulled out. The posture shown by the two-dot chain line in the figure is taken, and the elastic restoring force of the long body 1 acts to pull the annular body K upward, as shown by the arrow in the figure, opposite to the direction of action of gravity. Thus, the frictional force between the elongated body 1 and the lower peripheral support roller 3 can be reduced. As a result, even if the pulling force of the elongated body 1 is reduced, the elongated body 1 can be smoothly pulled out. Therefore, the overload on the lower peripheral support roller 3 is prevented, the durability of the support device S is improved, and furthermore, the occurrence of damage due to the overload on the wound elongated body 1 is prevented. It is also possible.

If each of the end face supporting rollers 5 is arranged on or substantially on the radiation with respect to the axis J of the annular body K, the end faces 4, 4 of the annular body K are connected to the end face supporting roller. When the guides are guided by 5, it is possible to abut the two 4 and 5 with the least frictional resistance, and it is possible to prevent the unnecessarily large frictional resistance from acting between the two 4 and 5. Becomes

[0009]

Therefore, according to the long body supporting device of the present invention, the wound long body can be pulled out with a small pulling force, and the operability and durability of the supporting device, and In addition, it is possible to prevent the long body from being damaged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. In the drawings, portions denoted by the same reference numerals as those of the conventional example indicate the same or corresponding portions.

In the present embodiment, a long-body support device (hereinafter simply referred to as a support device) S is used to lay a flexible long body 1 such as a resin pipe on a road. so,
Regarding a support device S for supporting the elongated body 1 in a state of being wound in a freely extendable manner, as shown in FIG. 1, a support frame 2 for supporting an annular body K around which the elongated body 1 is wound is provided. The support frame 2 is provided with a plurality of support rollers R provided so as to freely rotate and support the annular body K.

The elongated body 1 is a resin tube, has flexibility, and is set in a spirally wound state when it is set in the support device S. Put in. Here, the elongated body 1 spirally wound is referred to as an annular body K.

The support frame 2 is formed of a square pipe, and a pair of left and right main body frames 2A formed in a rectangular shape and the two are connected in a state where the support space V is secured between the pair of main body frames 2A. A plurality of connecting frames 2B, and a leg frame 2C for receiving and supporting the main body frame 2A. Each frame 2
A, 2B, and 2C are configured to be freely disassembled. Further, the leg frame 2C is provided with a slide mechanism that can be extended and contracted along its longitudinal direction, and is formed so that the distance between the legs can be changed.

The support roller R rotates a plurality of outer peripheral support rollers 3 which are individually contactable and rotatably supported at a plurality of positions on the outer peripheral portion of the annular body R, and both end faces 4 and 4 of the annular body K. A plurality of freely supporting end surface supporting rollers 5, an inner peripheral supporting roller 6 which can be inscribed in the long body 1, and a rotation of the long body 1 to a predetermined height at a portion where the long body is taken out from the supporting device S. An exit roller 7 that can be freely supported is provided. The outer peripheral support roller 3 is attached to both the main body frames 2A so that the rotation axis P is oriented in the direction along the axis J of the annular body K. Further, the plurality of outer peripheral support rollers 3
Among them, between the pair of outer peripheral support rollers 3a and 3b located diagonally downward in the radial direction of the annular body K, there is provided a feeding portion 8 capable of feeding one end of the elongated body 1 from the annular body K. It is. The end face supporting roller 5 is disposed on or substantially on the radiation with respect to the axis J of the annular body K set in a state of being in contact with each of the outer peripheral supporting rollers 3. That is, one end of the end surface supporting roller 5 is connected to the center shaft member 9 provided substantially at the position of the axis J of the annular body K.
The other end is separately connected to each corner of the main body frame 2A. The inner peripheral support roller 6 is provided across the two main body frames 3A so as to be located substantially in the radially opposite portion of the annular body K with respect to the position of the feeding portion 8.

According to the supporting device S of the present embodiment, when one end of the elongated body 1 is pulled out from the annular body K set in the support space V, the elastic restoring force of the elongated body 1 causes the annular body K to move by gravity. Acts upward to oppose the direction of action, and it is possible to reduce the frictional force between the elongated body 1 and the lower peripheral support roller 3, and smoothly pull out the elongated body 1 with a small force. Will be able to do it. As a result, the overload on the lower peripheral support roller 3 is prevented, the durability of the support device S is improved, and furthermore, the occurrence of damage due to the overload on the wound long body 1 is prevented. It is also possible to do.
