Description

Technical Field

[0001] The invention relates to the field of tunnel construction, and in particular to a method for using a multi-curvature steel bar storage and hoisting device. Background Art

[0002] The cross-section of a high-speed railway tunnel is not necessarily the same. The high-speed railway tunnel line is long and the tunnel cross-section is large. The same line but different geological conditions and design requirements will lead to different sizes of tunnel cross-sections. Therefore, the arc requirements of the steel bars used in the tunnel support structure are different.

[0003] The curvature requirements of the steel bars used are different, and the storage of steel bars requires multiple storage racks with different curvatures. The flexibility is poor and cannot meet different construction requirements. When facing the needs of multiple curvatures of steel bars, it is necessary to prepare multiple storage racks of different specifications, and the space utilization rate is low. Due to the special nature of the storage racks, a large amount of space may be occupied by unused storage racks at certain times, while the steel bars that are really needed cannot be stored due to insufficient storage space, thereby reducing the overall storage space utilization rate. At the same time, different curvature steel bars require different lifting equipment for lifting steel bars, so that the structure of the lifting equipment can adapt to the specific curvature of the steel bars to ensure safe and effective handling. Multiple sets of lifting equipment increase the equipment cost and the difficulty of lifting equipment management. At the same time, the existing lifting equipment cannot be clamped on the storage rack, resulting in the inability to automatically lift and install the tunnel support structure, and the steel bar construction efficiency is low. For this reason, we propose a method for using a multi-curvature steel bar storage and lifting device to solve the above problems. Summary of the invention

The storage rack 7 is used to store multiple curved steel bars 8. According to the structure, a plurality of arc-shaped steel bars are placed on the storage rack 7, the rotating platform 303 of the crane 3 is driven to place the horizontal hanger 4 on the storage rack 7, the first motor 403 and the plurality of hoists 404 of the horizontal hanger 4 are driven to place the two side hangers 5 near the upper parts of the two ends of the arc-shaped steel bars 8, the middle hanger 6 is located near the upper part of the middle end of the arc-shaped steel bars 8, the second motor 606 of the middle hanger 6 is driven to rotate the arc-shaped frame 601 so that the second installation slot 607 of the arc-shaped frame 601 opens downward, the hoist 404 on the middle hanger 6 is driven so that a plurality of steel bars 8 are located on the middle hanger 6, and the second partition plate 609 of the middle hanger 6 is driven so that the middle hanger 6 clamps a plurality of steel bars 8. The side hangers 5 are manually rotated so that the hangers 501 rotate relative to the rotating seat 502, the installation slot 5011 opens downward, the hoists 404 on the side hangers 5 are driven, and the second cylinder 10 is driven so that the second installation slot 607 clamps a plurality of steel bars 8.

[0022] Drive multiple hoists 404 at the same time to raise the side hangers 5 and the middle hanger 6, drive the second motor 606 of the middle hanger 6 to make the arc frame 601 horizontal, and at the same time, multiple hangers 501 rotate relative to the rotating seat 502 to make multiple steel bars 8 horizontal, move the position of the crane 3 and the cross hanger 4 so that the multiple steel bars 8 are located above the trolley 1, and move the transverse motor on the cantilever beam 304 to make the cross hanger 4 move axially along the trolley 1.

[0023] When the horizontal hanger 4 is located at the first comb tooth groove, the partition bar 507 is raised, the second partition plate 609 of the middle hanger 6 is raised, and the loading bar 506 is pushed to move the multiple steel bars 8 horizontally, so that the end steel bars 8 are separated from the middle hanger 6, so that the end steel bars 8 are located between the pressure bar 503 and the lifting seat 504, the partition bar 507 and the second partition plate 609 are moved downward, and the first cylinder 9 and the rotating mechanism 508 are driven to move the end of the side hanger 5 clamping the steel bars 8 downward, so that the two ends of the steel bars 8 are inserted into the sleeves on both sides of the trolley 1, and the steel bars 8 are against the comb tooth grooves of the trolley 1, and the pressure is raised. The strip 503 is pushed horizontally to push the push strip 505 to move the side hanger 5 away from the steel bar 8 so that the end steel bar 8 is separated from the side hanger 5. At this time, the steel bar 8 is separated from the overall structure, and the multiple cylinders on the side hanger 5 are driven to reset the pressure strip 503, the lifting seat 504 and the push strip 505 of the side hanger 5.
