Description

Technical Field

[0001] The utility model relates to the technical field of pipeline hoisting, in particular to a large-scale air duct hoisting fixed hanger. Background Art

[0002] The large rooftop air ducts are welded steel pipes. After being spliced ​​on the ground, the air ducts are hoisted from a high altitude. The conventional pipe hoisting method is to use a sling to hook the pipe wall at both ends of the round pipe and then lift it. However, this method is not suitable for air ducts with large diameters, long lengths, and multiple sections. There will be problems such as unreliable binding and unstable shaking during the hoisting project, which increases the hoisting risk.

[0003] After searching, the application with patent number CN213452065U discloses a large air duct hoisting and fixing bracket, which includes two parallel beams, and multiple connecting beams for connecting the two beams are arranged between the two beams. Two air duct support rods are arranged at intervals on the upper side of the beam along the extension direction of the beam. One end of the air duct support rod is hinged to the beam, and the other end is used to abut the air duct to be hoisted. The air duct support rod is provided with a support adjustment rod on the side opposite to the other air duct support rod. The air duct can be hoisted by two sets of lifting ears, and the two sets of support rods limit and fix the air duct, which is simple and convenient.

[0004] However, since the support rod can only limit the left and right positions of the air duct and prevent it from rolling, the air duct may tilt forward and backward due to the different front and rear gravity during the hoisting process, causing the air duct to slip off the hanger, resulting in unstable fixation and low safety. At the same time, since two sets of lifting ears are used for hoisting, the hoisting stability is low, and the hanger is prone to tilting under the action of the air duct, resulting in low hoisting safety.

[0005] Therefore, we proposed a large-scale air duct hanging and fixing hanger. Utility Model Content

[0006] In view of the deficiencies of the prior art, the present invention provides a large-scale air duct hoisting and fixing hanger, which solves the problems of unstable air duct fixation and low hoisting stability in the existing device.

[0011] Preferably, the clamping block is triangular in shape, and the oblique side of the clamping block contacts the air duct, which can improve the stability of the clamping block's limit and ensure the stability of the air duct.

[0012] Preferably, the contact surface between the support wheel and the air duct is arc-shaped, which can improve the stability of the contact surface between the support wheel and the air duct and ensure that the air duct does not shake.

[0013] Preferably, the top surface of the connecting beam is coated with an anti-slip layer, which can improve the stability of the placement of the air duct.

[0016] 2. At the same time, through the setting of the first support beam, the second support beam and the lifting ring, the diagonal lifting rings are connected by lifting ropes, and the intersection of the lifting ropes is fixedly connected, so as to ensure that the distance from the intersection to each lifting ring is the same, thereby ensuring that the hanger is hoisted.
