Description

[0001] The present invention relates to a tong crane apparatus equipped with a self-centering wire breakaway prevention module,

More particularly, the present invention relates to a self-centering wire detachment prevention module, and more particularly, to a self-centering wire detachment prevention module having self-contained wire detachment preventing means mounted on a transfer means having a wire rope fastening structure, And more particularly, to a bucket cranage device equipped with a departure prevention module.

Various objects manufactured in the industrial field should be transferred by the transfer means to the post-process depending on the purpose. The most commonly used transport means is a barrel crane. In the case of slabs, they are manufactured through a casting process and are carried or loaded in a gripped state by a conveying means such as a barrel crane. Conventional barrel cranes transport the gripped slab from the playing process, where the destination is from a short distance to a relatively long distance. In order to improve workability and productivity during the transportation process, slab gripping of the crane should be performed quickly.

And the crane is engaged by the wire between the pick-up means and the crane when transported by a predetermined pickup means after the barrel grips the slab. Here, when the crane is fed through the pick-up means, the wire between the pick-up means and the crane is shaken in a specific direction due to the load applied to the crane and the slab gripped by the crane, . Further, when the slab, which is the object to be conveyed, is to be quickly transferred to various positions, the swinging on the crane is relatively large from the pick-up means, and as a result, the wire breakage occurs in the wire- .

Various attempts have been made in order to prevent the wire from escaping. However, most of them have a problem in that it is not effective enough to achieve the purpose of preventing wire deviation, and the installation cost is high, resulting in inefficiency.

Therefore, there is a disadvantage that effective and stable operation of the conveying means for conveying the object is not easy.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a front view of a barrel crane apparatus 100 mounted with an automatic wire breakaway prevention module according to an embodiment of the present invention. FIG. 2 is a perspective view of a barrel- A side view of the crane apparatus 100 is shown. FIG. 3 shows a state in which the guide plate unit 130 and the wire W of the barrel crane apparatus 100 equipped with the self-centering wire deviation prevention module shown in FIG. 1 are flowing. FIG. 4 is a partially enlarged view of a stopper S of the crane unit 100 with the self-centering wire detachment prevention module shown in FIG. 1 mounted thereon. 5 to 7 show a state in which the wire W is guided by the guide plate unit 130 of the barrel crane apparatus 100 equipped with the self-centering wire detachment prevention module according to FIG.

1 to 7, a crane unit 100 having a self-centering wire detachment prevention module according to an embodiment of the present invention includes a base body 110, a sheave unit, (130), and a binding unit (140).

The base body 110 receives various fixtures for binding the wire W between the sheave unit 120, the guide plate unit 130, the binding unit 140, and the transfer means. The size and shape of the base body 110 may be appropriately adjusted.

The sheave unit 120 is formed with a groove for mounting the wire W at the peripheral edge thereof. Here, the width and shape of the groove are variously formed according to the wire (W) standard. The sheave unit 120 is provided on the base body 110 so as to be rotatable on a predetermined axis.

When the plurality of sheave units 120 are provided, the plurality of sheave units 120 may be arranged in parallel with each other, and may be rotated coaxially with respect to one another.

The guide plate unit 130 is positioned on at least one side of both sides of the sheave unit 120 to prevent the wire W mounted on the sheave unit 120 from being detached. The guide plate unit 130 is provided adjacent to the sheave unit 120 on the base body 110 so as to guide the displacement flow of the wire W mounted on the sheave unit 120 . The guide plate unit 130 has a semi-closed loop shape and has at least a pair of mutually opposed faces.

The guide plate unit 130 is positioned to face at least one side of the sheave unit 120 and one or more guide members 131 for guiding the outside of the wire W are formed. That is, when the wire W flows toward the outside of the sheave unit 120, the guide plate unit 130 moves from the predetermined first position corresponding to the wire W to the predetermined second position Flow. Thereafter, the wire W is pulled inward of the sheave unit 120 by its own weight and returned to the first position.

Here, the pair of guide plate units 130 are each formed in a ring shape that is rounded from the outside to the inside on at least one side of the sheave unit 120, and are provided to be symmetrical to each other.

More specifically, the one end of the guide plate unit 130 is connected to the binding member 140 and is formed in a substantially C shape toward the center axis of the sheave unit 120. The other end of the guide plate unit 130 may protrude toward the outside of the sheave unit 120.

The guide plate unit 130 may be provided on either side of each of the sheave units 120 or on both sides thereof. When the guide plate is provided on both sides of the sheave unit 120, the guide plate unit 130 is engaged with the sheave unit 120.

Here, the guide plate unit 130 is bound to the guide member 131 with each other. The guide member 131 is formed with a groove for receiving the wire W, similar to the sheave unit 120. The guide member 131 may include a roller or the like. The guide member moves the guide plate unit 130 in accordance with the flow of the guide member due to the displacement flow of the wire W,

The binding member 140 is provided on the base body so that the guide plate unit 130 can constantly flow in response to the displacement flow of the wire W mounted on the sheave unit 120, And is coupled to the plate unit 130.

The binding member 140 is provided with a stopper S for restricting the guide plate unit 130 from flowing above a predetermined angle corresponding to the displacement flow of the wire W. [ The stopper S may be provided to support the guide plate unit 130 between one end of the guide plate unit 130 and the binding opening 140.

The guide plate unit 130 may have a separate depressed portion so that the guide plate unit 130 can smoothly flow toward the sheave unit 120. In addition, a predetermined protrusion may be formed to allow the guide plate unit 130 to flow more rapidly than the binding port 140.

The stopper (S) can adjust the thickness and height of the wire (W) so as to suitably restrict the displacement flow of the wire (W). However, the stopper S is not limited to being positioned only between the guide plate unit 130 and the binding hole 140, and may be applied in various modifications to the flow of the guide plate unit 130 .

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
