Disclosure of Invention
The to-be-solved problem of the utility model is to above not enough and provide one kind and adopt the sola steel sheet book to make when whole circle at large-scale thin wall penstock, solve because of the unable self weight that supports of the rigidity of steel sheet, appear collapsing down, bend, the uneven scheduling problem of tile both ends atress. The technical scheme is as follows:
a single-wheel pulley is hoisted on a main hook of a gantry crane through a hoisting ring, a hoisting rope penetrates through a pulley of the single-wheel pulley, shackles are fixed at two ends of the hoisting rope respectively, and the shackles are connected with a whole-circle tile of a thin-wall steel pipe through a locking device.
The locking device adopts a T-shaped locking device, and the front end of the T-shaped locking device is provided with a hoisting hole. When the steel pipe tile with the grouting holes in the pipe wall of the steel pipe is rolled, the T-shaped locking device penetrates through the grouting hole closest to the end part from the inner side of the tile, and penetrates through the hoisting hole in the T-shaped locking device at the outer side by using the shackle to form a hoisting point.
The ingot locking device can also adopt a bolt ingot locking device, and the bolt ingot locking device is characterized in that screw hole plates vertical to the groove-shaped plate are respectively arranged on the left side and the right side of the groove-shaped plate.
The lower end of the trough plate is provided with a clamping groove, and the upper end of the trough plate is provided with a lifting hole.
The screw hole plate is provided with a screw thread hole, and a bolt is matched in the screw thread hole.
Compared with the prior art, the utility model discloses the beneficial effect who has is:
the automatic balance auxiliary system comprises the portal crane, the lifting ring and the pulley, after one section of circular arc is pressed and rolled at the two ends of the tile, the portal crane, the automatic balance system and the steel plate locking device are used, external force is given from the two ends of the tile, the tile is prevented from collapsing downwards when being rolled, bending occurs, the two ends of the tile are stressed evenly under the automatic balance stress system, rolling of the large-sized thin-wall pressure steel pipe full-circle tile is achieved, investment and field use of large-sized special auxiliary equipment are reduced, and construction cost is reduced.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in figure 1, the utility model discloses a hoist and mount single round coaster 3 through rings 2 on door owner's hook 1, have lifting rope 4 to pass on single round coaster 3's the pulley, and 4 both ends of lifting rope are fixed respectively and are broken out 5, and break out 5 is connected through the locking spindle device with thin-walled steel pipe full circle tile 7.
As shown in fig. 2 and 4, the locking device adopts a T-shaped locking device 6, and a hoisting hole 6.1 is formed at the front end of the T-shaped locking device. When the steel pipe tile with the grouting holes in the pipe wall of the steel pipe is rolled, one end, with the hoisting hole, of the T-shaped locking device penetrates through the grouting hole 7.1 closest to the end part from the inner side of the tile, and penetrates through the hoisting hole 6.1 in the T-shaped locking device at the outer side by using the shackle 5, so that a hoisting point is formed.
As shown in fig. 3 and 5, the locking device can also adopt a bolt locking device 9, and the bolt locking device 9 is characterized in that screw hole plates 9.1 vertical to the slotted plate are respectively arranged at the front and the back of the slotted plate 9.3.
The lower end of the groove-shaped plate 9.3 is provided with a clamping groove 9.31, and the upper end is provided with a lifting hole 9.32.
The threaded hole plate 9.1 is provided with a threaded hole, and a bolt 9.2 is matched in the threaded hole.
When steel pipe tiles without grouting holes on the pipe wall of the steel pipe are rolled, clamping grooves 9.31 of the bolt locking device vertically clamp the tiles 7 from two sides of the tiles at a position 1-1.5 m away from the end parts of the tiles 7, then the bolts 9.2 are screwed, and shackles 5 penetrate through lifting holes 9.32 on the bolt locking device; and a steel wire rope is used for connecting the two locking ingot devices at the same end, and a lifting point is formed on the width center of the tile.
As shown in fig. 6, after the two ends of the steel pipe tile are rolled to form a section of arc length, the shackle 5 of the auxiliary system is connected with a hanging point formed by the locking device, the main hook 1 of the gantry crane is lifted, so that the two ends of the tile 7 are stressed by tension, under the action of the pulleys, the two ends of the steel wire rope are always stressed the same, and the length is automatically adjusted along with the change of the height difference of the two ends of the tile, so that the two ends of the tile are stressed uniformly. In the rolling process, the change conditions of the increase of the rolling arc length and the left and right length at the two ends of the tile are observed, the position of a gantry crane and the height of a main hook are adjusted in time, so that a gantry crane lifting hook is in a vertical stress state, and when the two ends of the tile do not collapse obviously, rolling is continued until the rolling of the full-circle tile is finished.
In the figure 8, a plate bending machine is shown.
