Description

Cross arm open / cross display device for barrel crane

The present invention relates to an open-cross display device of a cross-screw for cross-screws that can check the open or cross state of the cross-arms installed in the lower portion of the through-screw moving the slab.

In general, slabs produced in hot rolling mills of steel mills are moved by gripping cranes.

Conventionally, when the slab is moved by the barrel crane, after confirming information such as the width and weight of the slab displayed on the terminal installed in the cab, the cross arm installed at the lower portion of the barrel crane according to the width or weight of the slab is opened and crossed. The driver in the cab is manipulating the crossarm to grip the slab.

However, when the slab is moved by the conventional barrel crane, information such as the width and weight of the slab can be accurately obtained through the terminal installed in the cab, but the cross arm is installed at the lower part of the barrel crane to hold and move the slab. Alternatively, the cross state, that is, the degree of opening is performed by visual confirmation of the driver who is driving. Therefore, it is impossible to confirm the correct opening degree and the work is made according to the skill of the driver. Since the work of the slab to move a lot of work time, there was a problem such as excessive power consumption according to the work.

The present invention is devised to solve the above problems, the present invention is the cross-arm for the cross-screw crane can move the slab quickly and easily by the operator of the cab to check the opening degree of the cross-arm by the display unit installed in the barrel screen Its purpose is to provide an open, cross-display of.

The present invention for achieving the above object is in the barrel of the cross-screw holding the slab while moving open or cross, the rack fixed to one side of the cross-arm installed in the lower portion of the barrel, the rack and the rack A drive shaft having a pinion gear-coupled thereto and having a first bevel gear fixed to the other side thereof, a second bevel gear geared to the first bevel gear fixed thereto and a rotating shaft having a third bevel gear fixed thereto; It consists of a display needle provided with a fourth bevel gear coupled to the third bevel gear, and a display plate marked on the back of the display needle.

Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 3.

1 is a perspective view of a barrel crane provided with a display device according to the present invention, Figure 2 is a front view of a barrel crane equipped with a display device according to the present invention, Figure 3 is an enlarged perspective view of the main portion of the display device according to the present invention, The invention is a plurality of links (1) is provided on both sides of the barrel crane (A), respectively, and the upper frame (2) and the lower frame (3) are respectively installed on the upper and lower portions of the link (1) and the upper frame ( 2), a first roller 2b wound around the first wire 2a is provided, and a second roller 3b wound around the second wire 3a is provided on the lower frame 3.

The rack 10 is fixed to one side of the cross arm 4 installed at the lower part of the link 1 by a fixing bolt 11, and one side of the rack 10 is inserted into the upper frame 3. The pinion 21 geared to the rack 10 is fixed to the drive shaft 20 inside the upper frame 3.

Meanwhile, the first bevel gear 22 is fixed to the other side of the drive shaft 20, and the second bevel gear 31 is gear-coupled to the first bevel gear 22, which is fixed by the rotation shaft 30. have.

A third bevel gear 32 is fixed to the other end of the rotation shaft 30, and a fourth bevel gear 41 is gear-coupled to the third bevel gear 32 and the fourth bevel gear 41 is coupled to the third bevel gear 32. Is fixed to the lower portion of the indicator needle 40.

The display panel 50 positioned behind the display needle 40 is installed on the upper frame 3, and a scale is displayed on the front of the display panel 50.

The present invention configured as described above, after confirming information such as the width and weight of the slab (5) displayed on the terminal installed in the cab and operating the cylinder crane (A), installed on the upper frame (2) of the cylinder crane (A) As the first wire 2a and the second wire 3a provided on the upper frame 3 move up and down, the cross arm 4 holding the slab 5 is opened or crossed.

Accordingly, when the cross arm 4 is opened or crossed, the rack 10 fixed to the side of the cross arm 4 by the fixing bolt 11 is moved together so that the pinion 21 is geared to the rack 10. ), And the rotational force of the pinion 21 is transmitted to the first bevel gear 22 fixed to the other side thereof through the drive shaft 20.

When the first bevel gear 22 rotates, the second bevel gear 31 geared thereto rotates, and this rotational force is transmitted to the rotating shaft 30 to which the second bevel gear 31 is fixed, thereby rotating the shaft. The third bevel gear 32 fixed to 30 is rotated.

When the third bevel gear 32 rotates, the fourth bevel gear 41 geared thereto rotates, and at the same time, the display needle 40 on which the fourth bevel gear 41 is fixed rotates.

Therefore, the driver of the cab can grasp the slab 5 while checking the opening degree of the cross arm 4 according to the scale displayed by the indicator needle 40.

As described above, the present invention is a simple operation of checking the scale of the display panel 50 indicated by the indicator needle 40, so that the degree of opening of the cross arm 4 for moving the slab 5 can be accurately determined, and thus the working time. In addition to shortening the power consumption of the work can be minimized.
