The present invention relates to a overhead crane magnet beam moving device, and more particularly, a magnet beam for attaching a heavy plate transported onto the bed so as to be cut to meet the demand of the demand, and a thick plate attached thereto, each width center being in the longitudinal direction thereof. This invention relates to an overhead crane magnet beam shifting device that allows the longitudinal width center of the thick plate to be easily fitted with the traveling center of the gas cutter when seated on the bed.

In general, products with thicker than 20mm thickness or special steels cannot be sheared in the shearing process, so they are transferred to the cutting bed equipped with a gas cutter through the transfer facility during the operation and cut into dimensions that meet the demands of the demand. do.

At this time, the transport facility used, as shown in Figure 1a, consists of a magnet beam 11 which is raised and lowered by the wire rope 14 and a magnet port 12 connected to the bottom surface of the magnet beam 11 As a result, the magnet port 12 is attached to the rear plate 13 and then transported onto the bed 122.

However, when the thick plate 13 is attached to the magnet port 12 during the thick plate transfer process, a phenomenon in which the thick plate 13 and the magnet beam 11 are displaced in parallel to each other in the longitudinal direction is caused by various factors. As the seat 122 is seated on the bed 122, the longitudinal center line of the rear plate 13 and the traveling line of the gas cutter 121 do not coincide, which causes a problem of cutting failure.

In order to solve this problem, conventionally, when the rear plate is received on the cutting bed 122, the operator pushes the end of the rear plate 13 by a manpower using a lever or has a weight that the operator cannot do. In the case of the rear plate 13, the lift magnet 1 port or the end port of the overhead crane is attached and slightly lifted, and then the rear plate 13 is used to align the longitudinal center line of the rear plate 13 with the running side center line of the gas cutter 121. In the process of pushing and pulling, the steel plate and the rear plate 13 on the bed 122 are rubbed, causing scratches, and of course, a safety accident may occur while the worker corrects the center line using the lever. There was a problem that can cause a delay.

In solving the problems as described above, the present invention provides a thick plate and to prevent damage to the product and safety accidents or work delay that may occur when the center line of the bed and the center line of the back plate does not coincide when wearing the thick plate on the bed.

Pinion gear 23 gear-coupled to the rack gear 24 is composed of a reduction gear 22 shaft-coupled, and a drive motor 21 shaft-coupled to the reduction gear 22 again.

In addition, the magnet beam moving unit 20 includes a pair of limit switches 28a formed on the touch bar 29 formed at the other center portion of the sheave moving piece 26 and the stoppers 27a and 27b on one side of the guide 27. It is composed of a, 28b, the touch bar 29 formed on the sheave moving piece 26 is configured to operate the limit switch (28a, 28b) in close proximity to the stopper (27a, 27b) on one side of the guide (27).

The center display unit 40 is composed of two left and right center sensing bars 35a which contact the side edges of the rear plate 13 when the rear plate is attached to the magnet beam 11.

The center sensing bar 35a is connected to the center sensing bar support 35b to be drooped downward by its own load based on the bar operating point 36, and the weight of each of the left and right center sensing bars 35a is the same. do. The upper portion of the center sensing bar (35a) is configured to be rotatably wound around the center indicator (37) via the turning roll (31) from one side to the other side using the center moving rope (32a).

As shown in FIG. 3B, a groove is formed in the center base 33 so that the weight piece 33a is inserted and movable up and down, and a cover for preventing the weight piece 33a from being separated out of the groove ( 33b) is fastened by the fastening bolt 39b. A disc shaped sieve type center indicator 37 is fitted to the indicator shaft 34 attached to the weight piece 33a so that it can be rotated clockwise or counterclockwise. 38) is provided so that the center is aligned when the direction of the center indicator 38 is vertical.

In addition, the graduation luminaire 47 is for accurately seating the magnet beam 11 on the rear plate 13, the lens 43 can be inserted into the lamp 42 in the luminaire shade 41 and the distance is adjustable And a display film 44 having a ruler drawn thereon on the front surface of the lens.

The ruler portion of the display film 44 is drilled to allow light to pass through, and the remaining portion is made of a translucent material so that when the lamp 42 is illuminated on the surface of the thick plate 13, the translucent portion of the display film 44 represents a circle of the whole. Displayed in a circle, the shadow of the perforated ruler is configured so that the brightness of the light is different from that of the circular shadow.

Hereinafter, the operation of the present invention will be described in detail.

As shown in Figures 2 to 4 explored while explaining the above configuration, the magnet beam moving device of the overhead crane constituting the present invention, when the power is supplied to the crane, using the graduation luminaire 47 The magnet beam 11 is attached to the thick plate 13 by aligning the center position with the magnet beam 11 in the light of the thick plate 13.

When power is supplied to the drive motor 21 of the attached magnet beam moving unit, the pinion gear 23 rotates through the reduction gear 22 axially coupled to the drive motor 21,

When the rack gear 24 geared to the pinion gear 23 reciprocates, the sieve moving piece 26 moves back and forth while the sheave 15 fixed on the sieve moving piece 26 moves. .

When the touch bar 29 is close to the stoppers 27a and 27b while the sieve moving piece 26 moves, the limit switches 28a and 28b attached to the stoppers 27a and 27b are operated. Accordingly, the power is cut off and the mobile device is stopped.

The driving motor 21 is rotated when the left moving device is set to be backward when the right moving device is moved forward.                     

When the magnet beam 11 is attached to the rear plate 13, the magnet beam moving device moves back and forth by the driving motor 21 to drive the center display unit 40.

The center sensing bar 35a in the center display unit 40 is lowered before the rear plate 13 is attached, and the center sensing bar is located at the uppermost end of the inner groove of the center base 33. 35a is lifted upward so that the center indicator 37 moves downward in the inner groove of the center base 33,
