Description

Detachable crane motion monitoring system and method {DETACHABLE SYSTEM AND METHOD FOR MONITORING MOTION OF HEAVY MACHINERY}

The present invention relates to a detachable crane operation monitoring system and method.

In general, a crane is a mechanical device that is widely used to perform operations such as loading, unloading, and loading of objects such as coils at industrial sites. These cranes perform hoisting and hoisting work in order to lift or lower an object.

At this time, the hoisting operation means a crane lifting the object. When a crane performs an operation of loading an object on the ground to a ship, the object is placed on a pallet installed on the ground. The crane performs hoisting work by lowering the hoist toward an object placed on a pallet and raising the hoist when the object is coupled to the hoist. Further, the unloading operation means a crane lowering an object. When a crane performs an operation of loading an object on the ground to a ship, the crane performs an unloading operation by lowering the hoist to which the object is coupled to the ship.

On the other hand, the work using such a crane has a risk of collision with adjacent cranes and surrounding structures, and when a collision with adjacent cranes and surrounding structures occurs, it leads to a large-scale accident. Accordingly, there is an increasing demand for a monitoring device capable of preventing safety accidents by measuring the swing of a crane, rotation of a rotating part such as a trolley, hook drum, etc. during crane operation.

However, since cranes are expensive, leased cranes are mainly used at construction sites. At this time, since the structure of the crane is different depending on the manufacturer of the leased crane, there is a problem in that it is difficult to install the monitoring device on the crane because it is difficult to arbitrarily modify the crane even though the installation of the monitoring device is required.

Therefore, there is a need for research into a technology that can be easily installed in cranes of various structures and conveniently and accurately measure the rotation of the crane.

In this case, the extension part 1113 may extend from the end of the coupling part 1111 to have a wider width than the width of the end of the coupling part 1111 . Accordingly, at least one second insertion hole 1113a may be spaced apart from each other along the width direction of the extension part 1113 . In this case, the distance between the second insertion holes 1113a located at the outermost side of the extension 1113 in the width direction may be substantially the same as the distance between the pair of first bars 121 . In addition, the distance between the second insertion hole 1113a located at the center of the extension part 1113 in the width direction and the first insertion hole 1111a of the coupling part 1111 is the distance between the pair of first bars 121. may be substantially the same as

Meanwhile, a direction in which the coupling body 111 is connected to the first bar 121 may be determined based on the structure of the rotating part 21 . For example, as shown in FIG. 3 , in a state in which the extension direction of the coupling part 111 is substantially horizontal to the extension directions of the third bar 141 and the fourth bar 143, the pair of first One bar 121 may be fastened to the coupling part 1111. In this case, the pair of first bars 121 may be inserted into the second insertion holes 1113a, respectively. The fixing unit 190 is fitted to the outer circumferential surface of the first bar 121 inserted into the second insertion hole 1113a, and the fixing unit 190 and the coupling body ( 111) is fastened, the first bar 121 may be fixed to the coupling body 111.

Accordingly, when an external force is applied to the first cover part 131 , the first cover part 131 may move along the extension direction of the first bar 121 and the second bar 123 . At this time, when the encoder 163 is in close contact with the rotating part 21, the movement of the first cover part 131 is completed, and the fixing unit 190 can be fitted into the outer circumferential surface of the second bar 123. . In this case, since the fixing unit 190 and the first cover part 131 are fastened through a separate fastening means and the second bar 123 is fixed to the first moving member 130, the first cover part 131 can no longer be moved.
