Description

Device for conversion of direction for heavy articles

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a device for turning heavy materials that must be cast to finish the surface, and more particularly to a device for turning heavy materials during the processing of large weights such as ship propellers.

When casting heavy materials like conventional ship propeller and then finishing the surface, the direction of the object should be rotated for the machining of the difficult or impossible part such as the back or side after processing the front side. Because of its large size and weight, it was impossible to move or change direction manually. Therefore, such a large and heavy object should be lifted by a crane and then turned in the desired direction and placed on the machining platform, thus occupying enormous force and large space. It was also flawed, inefficient, and risk-prone, with damage to the surrounding equipment and the weight to be machined, or the risk of an accident.

Therefore, as a device capable of facilitating the finishing process while switching the direction of the heavy material to be processed by eliminating the above-mentioned drawbacks, as shown in FIG. 3, the central axis 10 (10) of the center 10 `) A plurality of support devices (30) (30`) consisting of a pair of male and female support arms (20, 20`), the lower end of which is coupled to the teeth (50) ( 50 '(50') teeth (50) (50 ') of the toothed guide plate 40 (40`) etched wheels 70, 70a, 70' (70a ') to engage the handle (60, 60a) The heavy material 70 to be processed is rotated back and forth about the central axis 10 (10 ') while moving in the circumferential direction by (60') (60a ') on one side of the support arm (20). In order to work on the surface of one side and to process the surface on the opposite side, the support arm 20` of the other side is rotated toward the one side of the support arm 20 so that the weight 70 can be completely loaded. After gripping, it can be rotated to the other side to process the opposite side of the weight to be processed, but in the case of this device, the support arms 20 (20`) should be collected to one side about the central axis (10) (10`) and moved to the other side. Therefore, in addition to the load of the support arms 20, 20`, as well as the load of the workpiece, all the centers of gravity are concentrated on the central axes 10, 10` and the central axes 10, 10` and the support arms ( 20) (20 '), teeth 50 (50') of toothed guide plate 40 (40 ') and toothed wheel (70) of handle (60) (60a) (60') (60a ') (70a) (70 ') (70a') is a defect that is prone to wear, damage and bending due to the concentrated load.

The present invention improves the shortcomings of the direction changer for the processing of the large-scale processing of the conventional large-weight as described above, easy to mount the weight of the workpiece to be processed, and can be processed while easily changing the direction of the heavy processing weight by the vertical direction change It will be described in detail with reference to the accompanying drawings to provide a direction change device for processing a heavy object as follows.

Vertical supports 11, 11` are provided on both sides of the substrate 10, and large horizontal rotating gears 1, 1` are mounted on the upper inner wall of the support and rotated back and forth by the gears. Vertical rotating arms (4) and (4`) are installed so that one end of the vertical rotating arm (2) and (2`) horizontally rotates the inner end of the horizontal rotating arms (3) and (3`) horizontally from side to side. To the other end of the vertical rotation arm (4) and (4 ') to secure the detachable pin (7) (7`) for inserting the gripping groove (8) (8') of the outer end of the horizontal rotation arm When the pins 7 (7`) and the gripping grooves (8) (8`) are engaged, the caps (9) (9`) for preventing their release are inserted thereon and the horizontal rotary arm (3) (3`) At the center of the heavy material grip portion 5, 5, which is concave with a flat upper end, which is raised and lowered while being guided by a hydraulic or pneumatic cylinder 14, 14 'and guide rods 13, 13'. ') Is mounted face up and down Location close to the amount of vertical support (10) is configured to be a spring device (12, 12`) that elastically beneath the outer surface of the horizontal rotating arm (3) (3`) mounted.

The heavy object rotating device for processing according to the present invention configured as described above is formed by casting a heavy object such as a ship propeller, and then flips the upper horizontal rotating arm 3 of the present rotating device by the rotation of the small horizontal rotating gear 2 to the side. After the upper part of the device is opened, the heavy object propeller, etc. to be processed is lifted by a crane and placed on the heavy material holding part 5 'of the horizontal rotating arm 3' positioned at the lower part of the horizontal rotating arm 3 Guide the upper heavy gripping portion (5) to the guide rod (13), lift it slightly with the cylinder (14), place it in the center of the upper part of the flopella, and then lower the cylinder (14) again to fully retract the horizontal rotating arm (3). When the propeller is gripped, the gripping groove 8 'formed at the outer end of the horizontal rotating arm 3 is inserted into the detachable pin 7' formed on the vertical rotating arm 4 '. Wear) When the pin (7 ') is inserted, the cap (9) is attached to it and the horizontal rotating arm (3) is fixed to fix the propeller, and then the surface visible from the front of the propeller is processed. Rotating the vertical rotating arms (4) and (4 ') up and down by the rotary gears (1) and (1') changes the position of the upper and lower horizontal rotating arms (3) and (3 ') so that the upper horizontal rotating arm (3) is lowered. Go to the lower horizontal rotary arm (3 ') is going up to reverse the propeller, so the front and rear of the propeller is changed to be able to process the unprocessed portion of the rear from the front.

In the rotating apparatus for heavy object processing of the present invention, the horizontal rotating apparatus (3) (3 ') and the vertical rotating apparatus (4) (4') are formed by the small and small horizontal rotating gears (1) (1 ') (2) (2'). Since it is easy to rotate while maintaining balance, there is an advantage that it is easy to change the direction in order to process one side by mounting the weight.
