Description

[Detailed explanation of the idea] The present invention relates to a block reversing device.

When processing blocks such as steel structures, it is necessary to transport the blocks and turn them over for processing such as welding on both the front and back sides.
As shown in the perspective view of FIG. 1, in order to invert a relatively large block made up of a large number of shaped steels 02 with thin plates 01 attached, in the past, hanging pieces 03 were attached at 4 to 8 locations on the shaped steel 02 in advance. After welding and using this to turn it over using a crane, this hanging piece 03 is removed by gas cutting.

If the block is heavy or has a large shape, two cranes are used to reverse the block, first the block is hoisted horizontally with the surface facing up using the main crane and the sub crane, and then
After loosening the slave crane and attaching the slave crane to the back side of the block with the block lifted only by the main crane, drive the slave crane again and lift it until it is horizontal with the back side facing up. The crane is gently loosened at the same time, and the block is lowered to the ground while keeping it level. Therefore, in order to safely carry out the above-mentioned reversal work, a highly skilled worker is required, and it also requires a lot of time and effort. It's hanging.

The present invention has been proposed in view of the above circumstances, and aims to provide a labor-saving inversion device which can invert blocks safely and quickly without requiring a highly skilled worker, and which comprises a rectangular inversion frame formed by connecting the front ends and rear ends of a pair of equal-length horizontal members to each other at the front and rear of vertical members each having a plurality of stopper holes drilled at appropriate vertical intervals and arranged side by side in the front-to-rear direction, a bearing base which pivots one of the horizontal members, an eye plate protruding from the other horizontal member, and a bearing support which supports the upper and lower flanges of the H-shaped steel of each of the vertical members. a pair of front and rear movable horizontal members each having a grooved roller inserted between a pair of guide rails extending along the vertical member and pivotally mounted at both ends thereof and supported so as to be movable in parallel along the vertical member; two pairs of front and rear support arms each protruding opposite each other in the front-rear direction at both ends of each of the movable horizontal members and sandwiching the front and rear ends of the inverted block between the vertical members, respectively; and a stopper bolt which can be freely inserted and removed, which passes through a stopper hole formed at each end of each of the movable horizontal members and a stopper hole formed in each of the vertical members.

An embodiment of the present invention will be explained with reference to the drawings.
FIG. 2 is a plan view thereof, FIG. 3 is an enlarged side view of FIG. 2, and FIG. 4 is a sectional view taken along the line 〓--〓 of FIG.

In the above figure, 1 is a horizontal H-shaped steel 10 of approximately equal length, which connects both ends and the center of two longitudinal H-shaped steels 3, 3 of equal length parallel to each other with an appropriate interval.
A rectangular inverted frame body formed by connecting 10 and 10′,
4, 4 are longitudinal guide rails protruding along the upper and lower opposing surfaces of the inner flanges of the left and right vertical H-beams 3, 3, respectively, and 5 are the flanges of the left and right vertical H-beams 3, 3, respectively. A plurality of stopper holes drilled at regular intervals and distributed in the longitudinal direction,
6 and 6 are square tubular left and right gripping jigs, respectively.
Rollers 8, 8, which are externally inserted opposite to each other on the left side and right side of the vertical H-shaped steels 3, 3, respectively, and are pivotally connected to ear shafts 9, 9 that protrude inside the vertical H-shaped steels 3, It is attached movably along the guide rails 4, 4 of No. 3. Reference numeral 7 denotes a stopper hole drilled in each gripping jig 6, which corresponds to the stopper hole 5 drilled in the flange of the vertical H-shaped steel 3. 11 is the horizontal H-shaped steel 1 at the left end of the inversion frame 1
0, an eye plate 14 is established on the floor and has a pin shaft 15 at its upper end to pivot the right end of the reversing frame 1; 12 is a pair of left and right gripping jigs 6, 6, respectively; The lateral reinforcing members 13, 13 for fixing the lateral reinforcing members 13, 13 to each other are support arm members protruding from opposite surfaces of the lateral reinforcing members 12, 12 of the opposing gripping members 6, 6, respectively.

In such a device, first, a block that needs to be reversed is placed on the reversing frame 1, and when the reinforcing material portions of the gripping jigs 6, 6 are pushed manually, the gripping jigs 6, 6 are placed on the reversing frame 1. The block is run by rollers 8 on rails 4 provided in the block, and support arm members 13, 13 of opposing gripping jigs 6 sandwich the block.

Next, at this position, the stopper hole 7 of the gripping jig 6 is
and the stopper hole 5 of the reversing frame 1, and fix the gripping jig 6 to the reversing frame 1 with bolts and nuts.

Once the grasping jigs 6 on both sides have been set on the block in this way, a hanging device such as a shackle is attached to the eye plate 11, and the reversing frame 1 is lifted and suspended by a crane or the like, so that the reversing frame 1 can be secured to the pins of the bearing stand 14. Flip around axis 15.

When the reversal is completed, the bolts and nuts are unfastened, the gripping jig 6 is moved, and the blocks are disengaged.

According to such a device, there is no need for a plurality of hanging pieces that are conventionally welded to the block to be reversed as appropriate, and the man-hours required for their attachment, welding, and repair are also eliminated.

In this embodiment, the engaging portion is fixed, but if it is of a sliding type, it can be made to correspond to the size of the block.

In short, according to this device, a plurality of stopper holes are drilled at appropriate intervals in the vertical direction, and the front ends and rear ends of the vertical members made of left and right pairs of equal length H-beams are arranged side by side in the front and back direction. A rectangular inverting machine frame connected by horizontal members of equal length, a bearing stand for pivotally supporting one of the horizontal members, an eye plate protruding from the other of the horizontal members, and an H of each of the vertical members. A pair of front and rear movable rollers each having grooved rollers fitted between a pair of guide rails extending respectively along the upper and lower flanges of the shaped steel are pivoted at both ends and supported so as to be movable in parallel along the vertical member. a horizontal member, two pairs of front and rear support arms protruding from opposite ends of each of the movable horizontal members in the front-rear direction and sandwiching the front and rear ends of the block to be inverted between the vertical member; Reversal of the block for cost reduction by providing stopper holes drilled at both ends of the movable horizontal member and stopper bolts that can be inserted and removed freely through the stopper holes drilled in each of the vertical members. The present invention is industrially very useful because it provides a device.
