Abstract

A traveling crane auxiliary device is provided that prevents an object from rotating or swinging when the object is lifted and moved by a traveling crane. A hitch ball 9, which is a connecting ball, is provided at both ends of a balance bar that lifts an object, a guide post 8 that encloses the hitch ball and slides it vertically, and a guide wire 6 that translates the guide post. It is a traveling crane auxiliary device. The guide wire is formed by connecting one wire in a loop shape, but since it intersects at one point, it moves in the same direction as the balance rod 3 at the position 10 attached to the guide post. Although the suspension from the traveling crane is a single wire, the object can be safely moved without rotating. [Selection drawing] Fig. 1

Description

In the present invention, when an object suspended by a traveling crane, especially a roll-shaped object such as thread, cloth, paper, or a plastic sheet, is used to lift and move both ends of the shaft that is the core of the roll, the roll rotates. It is about preventing it from shaking and moving it stably.

Lifting and moving an object with a traveling crane installed in the ceiling or hollow is an effective means for saving labor at the production site. The object is lifted and lowered by winding devices such as wires and chain blocks, which are suspended from rails and move horizontally along the rails to move and store the objects or place them on production equipment. ..
For roll-shaped objects, it is necessary to hang both ends of the shaft that penetrates the center of the roll so as not to damage the load. Hang and move.

The problem that this case is trying to solve

As long as there is only one wire from the winder, horizontal rotation and shaking of the object will occur. If the object rotates or shakes while moving, it will interfere with surrounding equipment and buildings, damaging the load and causing safety problems. Therefore, measures such as suspending the object to move it and surrounding the moving range of the object with an iron frame in order to stably place it on the predetermined position and production equipment are taken, but it is extremely large as a device. It has become.

Means to solve problems

The present invention assists the object suspended by the balance rod to be stably translated along the traveling crane without rotating while using one traveling crane rail and one winding wire. It is a device. It is easy to configure and install and costs less to solve the problem.

The object to be suspended is a heavy object, but the load rests on the take-up device installed in the traveling crane. The guide wire used in the present invention bears only a small load to suppress the rotation of the suspended object.

The guide wires used in the present invention and fastened to both ends of the balance pole are arranged on the left and right sides of the balance pole in parallel with the rail of the traveling crane, but one wire is formed into one loop while changing the direction by the pulley.
The guide wires that are loops are not always parallel on the left and right, but are crossed at one place so that they move in the same direction at the balance rod mounting part. As the traveling crane moves, the balance pole moves in parallel without rotating. The movement of the balance pole is carried out by the traveling device of the traveling crane, and the guide wire moves by being dragged by the balance rod.

The present invention assists the parallel horizontal movement of an object suspended by a traveling crane. The balance pole that lifts the object is raised and lowered by the winding device. Since the hitch ball, which is a connecting ball attached to the left and right of the balance pole, moves up and down in the guide post, the balance pole does not rotate.
When connecting the guide post and the guide wire, it is desirable to take a long mounting contact with the guide wire in order to prevent the guide post from swinging like a pendulum.
When the take-up device attached to the traveling crane operates, the hitch balls at both ends of the balance rod move up and down in the guide post, and when the traveling crane operates, the balance rod moves the guide post back and forth using the hitch balls at both ends. ..

Hereinafter, an embodiment will be described with reference to [FIG. 1] according to the attached drawings. Reference numeral 1 is a roll-shaped object having a shaft 2 at the center of the axis. To lift the object without damaging it, suspend the shaft 2 or the periphery of the shaft using the lifting bands 5 at both ends of the balance rod 3, and lift the center of the balance rod 3 using a wire 4 such as a chain block using a winder. Hitch balls 10 are attached to both ends of the balance rod 3 and are stored in the guide post 9. When the winding device is activated and the balance rod 3 moves up and down, the hitch ball 10 moves up and down in the guide post 9 to assist the vertical movement of the balance rod 3. The upper part of the guide post 9 is attached to the guide wire 6 and moves in conjunction with the horizontal movement of the balance rod 3. The guide wire 6 is connected as one loop by a pulley 7, but moves in conjunction with the balance rod 3 because a part of the guide wire 6 is interlaced. [Fig. 2] and [Fig. 3] supplementarily explain the guide post and the attachment portion of the guide post and the guide wire.

In the embodiment of the present invention, although the lifting wire 4 for lifting the balance rod 3 is one, the balance rod 3, that is, the lifting object 1 can move without rotating or shaking.
