Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, and more specifically, to a civil engineering hoisting device. Background Art
[0002] Rebar plays an extremely important role in civil engineering. As the skeleton of concrete, it can significantly improve the bearing capacity of building structures. When concrete is subjected to external loads, the rebar can withstand tensile stress and shear stress, thereby preventing excessive deformation or damage to the structure. Therefore, when carrying out reinforced concrete construction, it is often necessary to hoist and move the rebar.
[0003] In the existing process of lifting steel bars, clamping equipment is usually used to clamp bundles of steel bars. However, when lifting steel bars, the existing clamping equipment often only adopts two-point lifting in front and behind the steel bars, resulting in the central part of the steel bars drooping due to its own gravity during lifting, affecting the stability during the lifting process, and the existing clamping equipment cannot effectively fix the clamping equipment after clamping the steel bars, making the clamping equipment easy to loosen, resulting in the steel bars easily falling during the lifting process, which will cause safety hazards.

[0030] In this embodiment, when the bundled steel bars are hoisted, the moving hand wheel 19 is rotated according to the length of the steel bars, and the moving hand wheel 19 drives the moving screw 18 to rotate, and the moving screw 18 drives the moving block 17 to move in the moving groove 16, thereby driving the fixing frame 2 to adjust the position, and the steel bars are inserted into the fixing frame 2, and the fixing ring 4 is rotated.

[0034] When the center part of the steel bar is hoisted and supported, the limit handle 25 is pulled to one side, so that the limit bar 23 leaves the ratchet gear 22 and the driving handle 15 is moved upward. The driving handle 15 drives the driving rack 14 to move upward, and drives the reset plate 27 to compress the reset spring 28. The driving rack 14 moves upward to drive the driving gear 13 to rotate. The rotation of the driving gear 13 drives the clamping plate 11 and the clamping claw 12 to move toward the center position to clamp the steel bar. After the clamping is stable, the limit handle 25 is released, the limit bar 23 is engaged with the ratchet gear 22, and the position of the driving gear 13 and the clamping screw 9 is fixed to prevent the clamping claw 12 from loosening, thereby clamping the center part of the steel bar, improving the hoisting safety.
