【発明の詳細な説明】 ［産業上の利用分野］ 電線の延線作業に於いて、鉄塔から懸垂する金車に駆

することを目的としたものである。[Detailed description of the invention] [Industrial application field] In wire drawing work, a driving force is applied to a wheel train suspended from a steel tower, thereby providing facilities for sending out the wire and winding the other end. The purpose of the present invention is to make a part of the work unnecessary and reduce the work area.

である。[Prior Art] In the wire drawing work, a large work area is required at a place where the electric wire is sent out and at a take-up place at a terminal end. As a countermeasure in this case, Japanese Patent Application Laid-Open No. 64-26315 is known. An electric wire is sandwiched between a pair of caterpillars opposed to each other in a horizontal plane, and this is used as an auxiliary driving force, thereby eliminating the necessity of a brake truck and a trailing wind pulling truck at a delivery site. However, in this device, each segment of the track is supported on a vertical axis. For this reason, support rollers are arranged before and after the tracks to adjust the vertical position of the electric wire when passing through the tracks. In other words, there is a problem that the supporting roller must be placed above or below the electric wire in accordance with the height position of the adjacent steel tower, and must be properly used each time. When the support roller is on the upper side, it is not allowed to reverse the caterpillar for adjusting the sag. This is because the electric wires may fall off from the caterpillar.
電線は対向するキャタピラが形成する垂直２平面間で
挾持するので、電線の送入送出には常時強い挾持力を必
要とする。このため接続クランプ、延線クランプ等大径
のものを通過させる場合、挾持力は過大となり、装置に
支障を来すことも起こる。Since the electric wire is clamped between two vertical planes formed by the opposing caterpillars, a strong clamping force is always required for sending and receiving the electric wire. For this reason, when a large-diameter member such as a connection clamp or a wire clamp is passed through, the clamping force becomes excessive, which may cause trouble for the device.
［問題点解決の手段］ 前記の問題点はすべて対向する垂直２平面間で電線を
挾持することに起因する。このため本発明では垂直面内
を水平移動するキャタピラで電線を支持し、これを上方

記の問題点はすべて解決される。[Means for Solving the Problems] All of the above problems are caused by clamping the electric wire between two opposed vertical planes. For this reason, in the present invention, an electric wire is supported by a caterpillar that moves horizontally in a vertical plane, and is pressed down from above by a pressing roller. This solves all of the above problems.

を副枠２の下端部3c（第３図）に固着されている。Example A drawing will be described. The main frame 1 is formed by binding four vertical members arranged in a rectangular shape at the top 1a, and is suspended by a steel tower.
The sub-frame 2 is disposed below each of the vertical members. This sub-frame is connected to a vertical member by a hinge 2a in a right row in a rectangular arrangement as shown in FIG. 2 and FIG.
Thereby, it is detachable from the vertical member. The guide frame 3 is formed by connecting a symmetrical triangular plate 1 having a convex arc shape at its upper part to a connecting member 3a, inserted between the front and rear rows of the vertical member, and connecting the front and rear surfaces to the lower end 3c (second end) of the sub-frame 2. 3).

を形成する。The chain 5 engages with the sprocket 4 and is movable along the guide edge 3b via a segment 6 described below. The segment 6 has a V-shaped groove on the surface, and both legs 6a project from the rear surface, and engage with the chain 5 to form a caterpillar.

てもよい（図示せず）。The V-shaped groove supports the electric wire at the bottom and can support a large-diameter one such as a connection clamp at the center. The segments are provided on both sides with rollers 6b, which roll on guide edges 3b. The pressing frame 7 has a concave arc shape on the lower surface, includes a pressing roller 8 capable of pressing down the electric wire E on the caterpillar, and a pressing hydraulic device C is provided. If necessary, a plurality of pressing rollers 8 may be connected by a chain and may be rotatable by another hydraulic motor (not shown).

も不要となる。[Operation] The present apparatus is configured as described above. The sub-frame is rotated by the hinge, and the electric wire E is positioned on the segment and closed. When the hydraulic motor M and the hydraulic device C are operated, the present device assists the operation of the reel winder at the end of the wire extension, and eliminates the need for a tow truck at the same. Further, since the electric wire coming out of the drum is braked by the present device, a braking vehicle at the starting point of the extension line is not required.

とが可能である。[Effect] Since the electric wire moves on the caterpillar while being pressed down by the roller, it is not necessary to provide a conventional support roller at the entrance and the exit of the apparatus. Even if the wire becomes loose, it will not fall from the device. By appropriately setting the V-shaped groove of the segment, a large diameter connection clamp or the like can be easily passed.
