Description

[0001] Crane monitoring apparatus [

The present invention relates to a crane monitoring apparatus, and more particularly, to a crane monitoring apparatus mounted on a crane driver's seat.

Currently, various crane devices are used for loading and unloading loads inside the factory or in ports. In the case of a port cranes to which heavy loads are transferred, as disclosed in Japanese Laid-Open Patent Publication No. 2011-0083249, a plurality of rails and a trolley for moving the lane image are mounted, a cabin is mounted on the top of the trolley, And a structure for adjusting the entire apparatus in the cabin.

Also, in the case of a crane used in a factory or the like, the port cranes differ in the structure that grips the load, and both have a similar structure in terms of the overall structure and the operation method.

On the other hand, the crane is constituted to include a device for sensing the weight of the loaded load, since the weight of the loaded load becomes an important factor for determining the safety of the entire device. The load sensing device can be implemented in various ways, but typically a load cell is used. For example, Japanese Laid-Open Patent Publication No. 2012-0040982 discloses a load cell unit for a knuckle crane having a boom rotating and deflecting in multiple stages and a grapple mounted on the boom to grasp and grasp the collected objects, An upper bracket coupled thereto; A lower bracket that is proximate to and spaced from the upper bracket and coupled to the grapple; And a load cell coupled to the lower bracket for measuring a load acting on the grapple by pressing the upper bracket.

In addition, Japanese Laid-Open Patent Publication No. 1999-0034688 discloses a load cell fixing bracket including a lower bracket extending around an upper portion of a load cell fixing bracket, an upper pin bracket inserted into the lower bracket and extending to a bottom portion of the upper crown, And a wire rope for connecting the wire rope to each of the wire ropes.

In addition, Japanese Unexamined Patent Application Publication No. 2011-0019242 discloses a crane equipped with a load cell capable of hanging a heavy object on a hook block and capable of measuring the load of the heavy object, ; A wireless communication unit for receiving the electric signal measured by the load cell and transmitting the electric signal to the receiving unit; And a self-generating unit adapted to supply electric power to the radio communication unit.

In the case of a large-capacity crane, as described above, a trolley for moving along a plurality of rails and a cabin mounted on the upper end of the trolley are installed. A load monitoring system for detecting a load of a heavy object is installed in the cabin. So that the weight of the weight to be loaded can be recognized.

At this time, the load monitoring system recognizes the deformation signal detected by the load cell or the like and informs the operator of the deformation signal, and a processing device for sensing the load using the signal of the load cell is generally built in the kevin.

On the other hand, in the case of a large crane installed on a yard, etc., it is an important factor to judge not only the weight of the load but also the stability of the wind direction and the wind speed. Therefore, a guide device for installing a wind direction anemometer on the outside of the cabin or trolley and guiding the wind direction wind speed according to the signal of the wind direction anemometer is also mounted inside the kevin so that the operator can recognize the wind direction wind speed, And load monitoring system are separately constructed and two display devices are installed in the inside of the kevin. However, since the conventional Kevin is manufactured with a very narrow inside, two display devices can not be arranged on the front surface of the kevin, and the display device of the load monitoring device is attached to the rear end and the display device for the wind directional speed is arranged Therefore, there is a disadvantage in that the operator can not recognize the wind speed and working load at one time, and the measured wind speed and working load can not be stored as one data.
