Description

[0001] DETECTING TYPE CRANE APPARATUS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a detaching type cranes, and more particularly, to a detaching type cranes which can easily detect slip gripping of the gripping means to enable more stable operation of the cranes.

The object to be manufactured through a predetermined process in the industrial field must necessarily have a means for transferring from a small size to a large size for mass production. For example, slabs are also manufactured through a casting process and transported or loaded in a ripped state by conveying means such as a barrel crane.

Typically, the barrel cranes are transported to a post-process as required in the performance process, and the destination is not only a short distance but also a relatively long distance. Therefore, the operator manipulates the slabs of the barrel cranes to quickly grip the barrel cranes in order to improve workability and productivity in the process of transporting the slabs to the destination.

However, in this process, the barrel cranes are conveyed toward the destination in a state in which the slab is not completely gripped, and the slabs are caused to flow due to sagging of the slabs, or the slabs are crashed.

Therefore, it is not easy to stably operate the slab for the slip cranes.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification. Throughout the specification, when an element is referred to as "comprising ", it means that it can include other elements as well, without excluding other elements unless specifically stated otherwise. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic front view of a crane unit 100 mounted with a gripping unit of a detecting type according to an embodiment of the present invention. 2 to 4 show a front view of a detaching type slave crane apparatus 100 according to Fig. FIG. 5 is a cross-sectional view of the contact unit 123 among the structures of the detaching type detaching type crane apparatus 100 according to the present invention shown in FIG.

Referring to FIG. 1, a detaching type cranage apparatus 100 according to an embodiment of the present invention includes a gripping unit 110, a control unit, a drive unit 120, and a guide member 130 do. The driving unit 120 includes a link unit 122, a rod L and a contact unit 123. The contact unit 123 includes a first body part 123a and a second body part 123b. 123b, and a sensing unit 123c.

The gripping unit 110 is provided on at least one pair of clamps on the barrel cranes to grip the slab S. The side surface of the slab S is gripped by the grip unit 110 and the upper surface of the slab S is brought into contact with the guide member 130.

The control unit controls the overall operation of the slaughter cranes. In particular, when the slaughter cranes descend, the control unit responds to the operation of the slaughtering unit 110 (e.g., the gripping speed, the gripping unit 110 ), The operation of the drive unit 120 (e.g., the operation of the cylinder unit 121, the advance and retreat of the contact unit 123, etc.), the operation of the guide member 130 (E.g., a win or a down). The operation of the grip unit 110, the driving unit 120, and the guide member 130 may be sequentially performed.

The driving unit 120 is embedded in at least one of the pair of gripping units 110 so as to detect whether the gripping unit 110 grips the slab S or not. The driving unit 120 is operated so as to be movable forward and backward on a region where the slab S on the gripping unit 110 is gripped.

The driving unit 120 is provided with a driving unit 120 that projects longitudinally on the one area of the grip unit 110 to detect whether the slab S is being gripped according to the operation of the vat crane Ready state. Therefore, the slab S is eventually ripped by the process shown in Figs. 2 to 4.

On the other hand, the cylinder unit 121 of the driving unit 120 allows the binding object to reciprocate. Here, the binding object corresponds to the link unit 122, and the link unit 122 is constantly flowed from the cylinder unit 121 to flow the contact unit 123.

The link unit 122 is interlocked with the cylinder unit 121 and is initially seated in a predetermined guide pin P in the grip unit 110 and is based on the operation of the cylinder unit 121 And is discharged from the guide pin (P) and flows toward the inside of the grip unit (110).

The contact unit 123 is located at an end of the link unit 122 and is advanced or retracted on the one area of the grip unit 110 according to the flow of the link unit 122, Lt; / RTI >

The contact unit 123 is configured to move from the inside of the gripping unit 110 to the outside of the gripping unit 110 based on an operation of the link unit 122 being separated from the guide pin P and directed toward the inside of the gripping unit 110 Respectively. The link unit 122 is rotatably engaged with the fastening member B in the grip unit 110 in the longitudinal direction.

5 to 6, the first body part 123a of the contact unit 123 is formed in a predetermined shape and is coupled to the first body part 123a, (E.g., a tubular body or the like).

The second body part 123b is coupled to the first body part 123a so as to be able to move forward and backward by an elastic restoring force via a rod L in the longitudinal direction. The second body part 123b is engaged with the first body part 123a and has a shape suitable for the flow of the rod L (e.g., a cylindrical body).

Here, the second body 123b is provided with a roller 123d at the longitudinal end thereof in contact with the slab portion at the time of gripping the slipping portion of the gripping unit 110. [ Therefore, when the second body part 123b comes into contact with the side surface of the slab part, the friction due to the flow is minimized, so that damage between the slab part and the grip unit 110 can be prevented.

The sensing unit 123c senses whether or not the slab S of the grip unit 110 is gripped through the rod L accommodated in the second body part 123b and flowing through the first body part 123a. Lt; / RTI > That is, the rod L is retracted to the rear end of the first body part 123a when the second body part 123b is retreated, based on the gripping of the slab S of the grip unit 110 Respectively. The sensing unit 123c senses whether the slip S of the grip unit 110 is gripped by detecting the rod L which is retreated to a predetermined region.

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.
