Description

Technical Field

[0001] The utility model relates to the field of steel cage lifting construction, in particular to a steel cage lifting device. Background Art

[0002] The Chinese invention patent application publication number CN 115893182 A discloses a steel cage lifting device and lifting method for stable transportation. It includes a crane, a winch installed on the crane, a mounting pipe for placing the steel cage, a seal installed at one end of the mounting pipe and detachably connected to the mounting pipe, and a lifting assembly for making the steel cage abut against the seal under the drive of the crane and the winch. The traction rope of the winch passes over the front end of the crane boom and hangs down, and the lifting assembly is connected to the traction rope. When lifting the steel cage, the steel cage is easily affected by wind force because the lifting rope is too long and soft, and the shaking amplitude is too large, which is easy to cause safety accidents. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a steel cage lifting device, which has good wind resistance during lifting, is not easy to shake, and can lift more stably.

[0004] In order to solve the above problems, a steel cage lifting device is adopted, which comprises:

[0005] A cross body, which includes four I-beam branches and a central part, and the four I-beam branches are fixed on the central part in a cross-shaped form;

[0006] Lifting lugs, which are fixed to the four I-beam branches;

[0007] The slider is slidably arranged on both sides of the I-beam branch, close to the web and upper and lower flanges of the I-beam. The slider is provided with holes for the suspension rod to pass vertically, and the upper end of the suspension rod is tightened on the slider through a nut;

[0008] A U-shaped hoop, which is arranged at the lower end of the suspension rod;

[0009] A lead screw, the thread of which passes through the slider and is rotatably connected to the central portion;

[0010] A hand crank, which is mounted on the end of the lead screw;

[0011] The support is fixed on the flange of the I-beam branch and rotatably mounts the end of the lead screw.

[0012] With this structure, when a crane is lifting a steel cage, the lifting rod is more wind-resistant than the lifting rope. After turning the lead screw, the slider can be adjusted to move along the I-beam branch. After moving, the radius can be easily adjusted to accommodate lifting steel cages of different radii.

[0013] As a further improvement of the present invention, the hand crank is Z-shaped, and the corners are right angles.

[0014] Such a structure makes it convenient to manually rotate the lead screw.

[0015] As a further improvement of the utility model, the U-shaped hoop includes a U-shaped rod and a bolt and nut kit for closing the U-shaped rod. After the U-shaped rod passes through the two holes opened at the lower end of the hanger, it is clamped on the hooks of the vertical steel bars of the steel cage, and then tightened and closed by the bolt and nut kit.

[0016] With such a structure, the U-shaped hoop is tightened by means of a bolt and nut set, so that the hooks of the hanger rod and the vertical steel bars of the steel cage are connected, making lifting easier.

[0017] As a further improvement of the utility model, a rubber sleeve is provided on the hand crank.

[0018] With this structure, the rubber sleeve is used to protect the hand.

[0019] As a further improvement of the utility model, the suspension rod is extended by a sleeve.

[0020] Adopting such a structure makes it easy to extend the boom.

[0021] As a further improvement of the utility model, the slider includes a top plate close to the upper flange of the I-beam branch, a bottom plate close to the lower flange of the I-beam branch, a vertical plate close to the web of the I-beam branch, and a rib plate located between the top plate, the bottom plate and the vertical plate. The vertical plate fixes the top plate and the bottom plate, the rib plate fixes the top plate, the bottom plate and the vertical plate, the top plate cantilevers out the upper flange, and has holes for the hanger to pass through, the holes are evenly spaced, and the vertical plate is for the lead screw to pass through in a threaded connection manner.

[0022] With such a structure, the slider can be lightweight, and the ribs can prevent the top plate from bending.

[0023] The utility model has good wind resistance effect during lifting, is not easy to shake, and lifts more steadily. BRIEF DESCRIPTION OF THE DRAWINGS
