[0002]

[Prior art and its problems]

 Conventionally, this type of connecting metal fitting has previously been connected to the hanging wire rope at its rear end side, and when unfolding the hanging wire car, it is sequentially connected to a fixed rope for towing the hanging wire car. Conventionally, the fixed rope was connected to the fixed rope by tightening bolts and the like.

However, since this connecting work is carried out at a high place of the steel tower, when it is carried out in the cold wind of winter, it is difficult and difficult to tighten the bolts and the like due to the clenching of the hands, etc. It caused a case that could not be done.

The present invention is to solve the above-mentioned problems, and an object thereof is to provide a connecting fitting for connecting a hanging wire rope and a fixed rope, which can easily perform a connecting operation with the fixed rope even in winter. And

[0005]

[Means for Solving the Problems]

 A connecting fitting according to the present invention is a connecting fitting for a hanging wire rope and a fixed rope for connecting a vertical hanging wire rope extending from a hanging wire wheel and a horizontal fixed rope for towing the hanging wire wheel. The rear end side is connected to the hanging wire rope, and the front end is provided with a hook part that can be locked to the fixed rope so as to be inverted to the rear end side, and between the rear end and the front end. A main body in which a square tubular frame portion is arranged, a holding cylinder in a substantially square tubular shape that can be externally mounted on the frame portion and the hook portion, and a rear end disposed in the main body and having the rear end of the main body. A coil spring for holding the front end on the holding cylinder and urging the holding cylinder toward the hook portion side, and the holding cylinder on the front end side, A cover part that can cover the tip of the hook part, and a coil part that extends parallel to the axial direction of the fixed rope. A holding rod that holds the tip of the spring; and a pair of claw pieces that bend inward so as to come close to each other at a portion of the rear end that faces the axial direction of the fixed rope. The distance between the tips of the pair of claw pieces is set to be slightly larger than the outer dimension of the frame portion when the pressing tube is exteriorly mounted on the frame portion, and the base of the pair of claw pieces covers the pressing tube. The dimension to the front end of the portion is longer than the dimension from the front end of the frame portion of the main body to the tip of the hook portion.

As a connection structure with the hanging wire rope on the rear end side of the main body, an insertion hole through which the hanging wire rope is inserted is formed on the rear end side of the main body, and the insertion hole is formed. A pair of locking holes are formed on the inner peripheral surface of the hole so as to face each other in the direction orthogonal to the insertion hole and extend in the axial direction of the coil spring, and the coil spring is fitted into the pair of locking holes. By locking both ends of the locking rod that holds the rear end of the knee, the hanging wire rope is inserted into the insertion hole and pressed by the locking rod, and is brought into pressure contact with the inner peripheral surface of the insertion hole. It may be connected to the rear end side of the main body.

Alternatively, a mounting piece having a mounting hole is formed on the rear end side of the main body, and a clamp member capable of holding the hanging wheel rope is attached to the mounting piece using the mounting hole. Alternatively, the hanging wire rope may be connected to the rear end side of the main body by using the clamp member.

Further, the main body frame portion and the presser cylinder have an outer periphery of the presser cylinder against the biasing force of the coil spring, and the tip of the hook and the presser cylinder cover portion. When the gap for locking the fixed rope with the hook portion is opened between the front end of the body and the holding barrel, the movement of the holding barrel due to the urging force of the coil spring is prevented between the body frame portion and the holding barrel. You may provide the through-hole which can insert the regulation rod which regulates.

[0009]

[Operation and effect of the device]

 In the connecting fitting according to the present invention, the rear end side of the main body is connected to the hanging wire rope in advance, and when the hanging wire is deployed, first, the holding cylinder is gripped to resist the biasing force of the coil spring. Move the presser tube rearward so that it will be externally attached to the main body frame, and open a gap between the tip of the main body hook and the front end of the presser tube cover so that the fixed rope can be locked to the hook. It

[0010] After that, the main body hook portion is locked to the fixed rope so that the fixed rope is inserted into the hook portion through the gap, and when the hand is released from the holding cylinder, the holding cylinder is urged by the coil spring. The hook moves to the front of the hook to cover the hook, and the fixed rope is clamped between the inner peripheral surface of the hook of the main body and the holding rod of the holding cylinder, and the connection work with the fixed rope is completed. Becomes

When the fixed rope is towed, the main body hook portion, which is a connecting portion with the fixed rope, comes ahead of the rear end side of the main body on the hanging wire rope side, and the holding rod of the presser tube becomes the fixed rope. As a result of being pushed, the axial direction of the holding cylinder is not coaxial with the axial direction of the main body frame portion, but is displaced in the towing direction of the fixed rope. In this case, the pressing cylinder should be opened in a direction that opens the space between the tip of the hook and the front end of the pressing cylinder cover, such as removing the fixed rope, that is, in the direction in which it is covered by the body frame. Will be moved to the rear.

However, in that case, the pair of claw pieces of the presser cylinder are arranged along the axial direction of the fixed rope, and the distance between the tips is set so that the frame of the presser cylinder is externally mounted. The dimensions are slightly larger than the external dimensions of the part. Therefore, the claw piece on the rear side of the towed direction of the fixed rope is inserted into the main body frame portion, and the claw piece or the peripheral edge thereof is brought into contact with the front end of the main body frame portion to restrict the movement of the holding cylinder. Furthermore, when the movement of the presser tube is restricted, make the dimension from the base of the pair of claw pieces to the front end of the presser tube cover longer than the dimension from the front end of the frame of the main body to the tip of the hook. Therefore, the presser tube keeps the condition that the hook part is exteriorized, and the fixed rope is held in the closed space surrounded by the inner peripheral surface of the hook part and the front end of the presser tube, and is fixed from the fixed rope connecting fitting. It is prevented from coming off.

Then, when the suspension wagon is withdrawn, the fixed rope is towed in the opposite direction, but at this time, the claw piece on the other side restricts the movement of the holding cylinder, and similarly to the above, the fixed rope is pulled. Can be prevented from coming off from the connecting fitting.

Therefore, the connecting fitting according to the present invention can be easily connected to the fixed rope by the operation of gripping the holding cylinder and moving it to the rear side, and then removing the hand from the holding cylinder. It is possible to easily perform the connecting work with the fixed rope even in the winter, and also to prevent the fixed rope from coming off after the connection.

When a predetermined through hole is provided in the main body frame portion and the presser cylinder, the presser tube is externally mounted on the frame part against the biasing force of the coil spring, and the tip of the hook portion and the presser cylinder are provided. After making a gap between the front end of the cover and the hook so that the fixed rope can be locked to the hook, insert a control rod into these through holes to prevent the pressing cylinder from moving due to the biasing force of the coil spring. Since it is possible to regulate, it is possible to maintain the standby state for locking to the fixed rope, and at the time of connecting work, it is convenient because the action of simply pulling out the regulating rod is sufficient.

Further, as a connection with the hanging wire rope, an insertion hole through which the hanging wire rope can be inserted is formed on the rear end side of the main body, and an inner peripheral surface of the insertion hole is orthogonal to the insertion hole. A pair of locking holes that are formed to face each other in the axial direction and extend in the axial direction of the coil spring, and lock both ends of the locking rod that holds the rear end of the coil spring into the pair of locking holes. , If the suspension wheel rope is inserted into the insertion hole and pressed against the locking rod so that it is pressed against the inner peripheral surface of the insertion hole and connected to the rear end side of the main body, When connecting to the rope, the locking rod can be moved to the front side to widen the inner diameter of the insertion hole against the biasing force of the coil spring, making it easy to insert the hanging wheel rope into the insertion hole. In addition, after inserting the hanging wagon rope into the insertion hole, if you remove your hand from the locking rod, The urging force of the il spring causes the locking rod to press the hanging wire rope into contact with the inner peripheral surface of the insertion hole, so that the hanging wire rope can be connected and the connection with the hanging wire rope is facilitated.

Further, as a connection with the hanging wagon rope, an attachment piece having a mounting hole is formed on the rear end side of the main body, and a clamp member capable of holding the hanging wagon rope is used in the mounting hole. Then, when attaching the hanging wagon rope to the rear end of the main body using the clamp member after attaching it to the mounting piece, use the clamp member even after fastening the hanging wagon with the hanging wagon rope. Then, the connecting metal fittings can be connected to the hanging wire rope, which is convenient.
