The present invention relates to a device for accurately confirming the number of slabs hoisted during hoisting operation after the towing of the tongs of the tongs crane, and for detecting when a slab other than the hoisted object is fused below the hoisting slabs, The present invention relates to a device for checking the number of hoisting slabs and detecting the number of hoisting slabs below the hoisting slab by detecting the number of hoisting slabs and installing the device on the safety technology of the CLTS side and the trolly side. .

The barrel crane, which is used as a facility for moving slabs in a steel mill's reproducing process, as shown in FIG. Is lowered to stop at the upper part of the slab (5), and during hoisting operation of the slab (5), the hoist motor operates in the reverse direction to raise the slab (5).

As shown in Fig. 2, the number of hoisting slabs should be checked in the crane cab 6 during the slab hoisting work of less than 4 sheets in the import or charging bed, but in the related art, the driver in the cab 6 had to confirm this directly. . However, it is difficult for the driver to visually check alone, so that the number of work order data and the number of spot work generated by the slab automation frequently occurs, and the work delay is caused by the difficulty of tracking slab information. In the hoisting operation of the slab 5 which is piled up on the yard, the crane motor burns down and falls while driving due to the fall of the slab 5 which is not the hoist object fused under the actual hoisting slab. There is a big problem of the risk of large equipment accidents and safety accidents.

The present invention is to solve the conventional problems as described above, problems in confirming the number of slabs generated during the slab hoisting operation after the lowering of the barrel crane, and the risk of large-scale equipment accidents and safety accidents due to the slab fused below the work slab It is an object of the present invention to provide a device for automatic recognition of the number of barrel crane slabs and the detection of fusion occurrence that can solve the factors.

Hereinafter, the operation of the present invention.                     

Referring to FIG. 5A, the light emitting sensor 56 of the slab automatic recognition and fusion occurrence detecting device installed on the CLTS side safety deck 7 and the trolley side safety deck 7 in the rising stop position of the tongs 4 of the tongs crane. The light emitting sensor 56 and the object detecting bracket 60 are adjusted to lie in a straight line so as to detect the lower end of the supporting block 8 of the tongs 4 and simultaneously detect one slab 5. The light sensor 56, the movable motor 62, the head length sensing device 72, and the power cable 93 of the multi-stage cam 74 are connected to the control panel 91 of the electric room and the operation panel 92 inside the cab. It is.

Referring to FIG. 5B, when the tongs 4 is lowered due to the hoist motor operation of the upper crab 2 of the girder 1 of the tong screed, the movable portion connected to the hoist motor operation contact of the upper crab 2 of the girder 1 is lowered. The motor 62, the head length sensing device 72, and the multi-stage cam 74 are operated simultaneously, and the light emitting sensor 56 of the device installed on the CLTS side safety deck 7 and the trolly side safety deck 7 According to the lowering of the tongs 4, the square plate 55 of the curved movable sensor device 51 is inclined toward the tongs 4 side. When the lowering of the tongs 4 is stopped by the hoist motor stop, the movable motor 62 is stopped. , The operation of the head length detection device 72 and the multi-stage cam 74 is stopped, and when the tongs 4 is raised by the hoist motor operation, the operation is reversed to the above, and the slab ( 5) When the gripping is performed, the square plate 55 of the curved movable sensor device 51 moves to the tongs 4 side. The number of slabs 5 detected through the respective taper holes 59 of the object detecting bracket 60 of the light emitting sensor 56 while the angle of inclination of the light source is gentle is reduced to the power cable 93 and the data cable 94. Through the transmission to the control panel 91 and the operating panel 92 in the cab through the Slab (5) to display the number of digital numbers. At this time, when the number of work orders generated by slab automation and the number of work order slabs (5) generated by CLTS are different, the alarm is generated and the digital number blinks, and the maximum number of gripping slabs (5) in the barrel (4) of the barrel crane If the fusion-producing slab 5 is detected by the light emitting sensor 56 through the taper hole 59 at the lower end of the object detecting bracket 60 of the light emitting sensor 56, the up to the rising stop position of the tongs 4 is detected.
