Description

  The present invention relates to an apparatus for securing a rope end that is configured as a part of a rope reel that winds a rope.

A long wire rope is a necessity for erection of overhead power lines.
Considering the convenience of transportation to the construction site, the wire rope is divided into lengths that are within a certain total weight, wound on a wire rope reel, and connected to multiple wires at the construction site. Used as a ruled wire rope.
Both ends of the wire rope are eye-processed by savory braids, etc., and dedicated connection fittings are used for connection.

When winding the wire rope, hang the eye processing part at one end of the wire rope on the rope end anchoring device equipped on the rope reel, and apply the necessary tension to the wire rope so that the wire rope can be wound without gaps. While rotating the rope reel with the power of a motor or the like, it is wound around the winding reel of the rope reel.
When pulling out the wire rope from the rope reel, the rope reel is gradually fed out while applying the brake so that the rope reel does not rotate freely, and the wire rope is pulled while applying tension to the wire rope.

  When connecting to the next wire rope in order to make it long, once the remaining number of times of winding of the wire rope in the winding drum section is several times, stop the pulling out operation, and attach the wire rope to a solid equipment etc. Temporarily hold the tension, make the end of the wire rope untensioned, remove it from the rope end anchoring device, connect the tip of the next wire rope to be connected with a connecting bracket, and re-tension. Pull it out.

  The tip of a wire rope that has been made into a closed loop shape by eye processing can be easily grasped and fixed, and the rotational force that tries to return to the original with the twist of the wire rope or the wire that is wound around the winding body of the rope reel Even if the repulsive force to the bending of the rope is intricately entangled and overlaps with the rope end anchoring device, it overlaps with the rope end anchoring device. An apparatus for securing a rope terminal that cannot be removed is provided.

  The present invention is not limited to a wire rope, but can also be applied to a fiber rope having an eye-finished end, an electric wire equipped with a suitable closed loop jig on the end, and the like.

  Up to now, there are many J-shaped tips with open ends, and the mounting positions vary depending on the manufacturer. In the case of deformed fittings, etc. Some of the rope's eye processed parts were easily removed.

  When winding on a rope reel, work with great care, so it was rare that problems would occur even though it was somewhat troublesome, but near the end of the wire rope when pulling out with tension during construction work, etc. When the rope end is not securely fastened, there is a concern that the wire rope may run away from the stage where the wire rope remains several times on the winding reel of the rope reel.

  For this reason, a wire rope is hung on the J-shaped rope end anchoring bracket, and a thin iron wire called a bind wire is used to prevent the wire rope from unintentionally coming out of the J-shaped rope end anchoring bracket. Measures to secure the rope-type end fittings and wire ropes were devised. However, this method is incomplete as a measure to prevent the wire rope eye processing part from coming off the rope end anchoring bracket, and the work performance of whether or not it can be firmly secured over time depends on the skill of the operator. Because it depends, there was a problem that it was not left to inexperienced workers.

  In considering a new rope end anchoring device, the wire rope that has been once sewn while being easy to attach and detach has a structure that does not come off naturally, and the size of the rope end anchoring device is the rope reel. From the viewpoint of preventing contact with the winding rope inside the edge of the rim, and from the viewpoint of preventing contact with other rope reels and equipment outside the rim, it was required to be within the edge thickness.

  In the present invention, a structure of an apparatus for securely fastening a rope end having a closed loop tip by eye processing or the like is provided by a simple procedure.

In Claim 1, the basic structure of a rope terminal anchoring device is provided.
There is a condition that the target rope has a closed loop-shaped tip by eye processing or the like, but it can be applied not only to the rope but also to electric wires etc. as long as it can process or connect a terminal with a closed loop structure similar to eye processing .

  As a basic structure, a U-shaped groove constituted by two fixed columns and a sealing part delivered so as to seal the opening of the groove are integrated. The sealing part is removed or rotated / bent to open the opening, one side of the closed loop part by rope eye processing is inserted into the groove, and the sealing part is attached, rotated, bent and fixed so as to seal the opening. After that, a structure having a function of not releasing the rope even when a normally considered tension or the like which is not excessive is applied is provided.

In claim 2, a bolt-shaped metal fitting is provided as a sealing part.
In general, various hooks equipped on cranes and the like are equipped with stoppers that are easy to close and open with springs, and work efficiency is good, but when a heavy load is applied with a thick wire rope etc. There is a concern that the sealing parts will be damaged. In that respect, if the thickness of the bolt is appropriately selected, it is possible to sufficiently withstand the load applied to the bolt body while reinforcing the strength of the column.

In claim 3, the detailed structure of the bolt provided in claim 2 is provided.
A wire rope or the like reaches the winding drum part from the rope terminal anchoring device along the edge of the rope reel, and is wound around the far side from the position in contact with the edge. In addition, since the distance between the two ropes of the closed loop portion by eye processing is larger than the thickness of the edge of the rope reel, the direction of the U-shaped groove of the rope end anchoring device is as follows. Necessary to be parallel and downward, and within the range of the thickness of the edge. Bolts as sealing parts must have sufficient and sufficient strength, and should not be extended from the thickness of the edge. There was a need. For this reason, it is convenient to omit the nut and cut the female screw directly on one of the columns, and to make the bolt head part as thin as possible and to settle on the column opposite to the female screw.

  In claim 5, as a method of giving a tightening rotational torque to a bolt as a sealing part, a hexagonal wrench that is always provided at the construction site and does not require the bolt head to be exposed outside the column. Hexagon socket head cap screws are used.

  According to the present invention, it is easy to connect a wire rope or the like to a rope end locking device of a rope reel, and prevention of disconnection of the wire rope or the like from the rope terminal locking device is ensured even for an inexperienced worker. Can be implemented.

  In addition, the rope reel and the wire rope are connected even in the unlikely event that the wire rope is accidentally run away due to unpredictable tension as the wire rope from the rope end anchoring device is reliably prevented and strong. Keeps the wire rope end free.

It is the schematic diagram of the state which started winding the rope reel 11 and the wire rope 10 grade | etc., To it. The tip of the wire rope 10 has an eye-finished closed loop, and the closed loop portion is fixed to a rope terminal anchoring device, and the wire rope 10 is wound around the winding drum portion of the rope reel 11.
