Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting frames, and in particular relates to a hoisting frame for a prefabricated hollow slab beam reinforcement cage. Background Art

[0002] When most hollow slab beams are hoisted, the protruding steel bars are often used as the fixing points of the hoisting hooks. This hoisting method can easily cause deformation of the steel cage and damage to the binding points and welding points. It is very unfavorable for the overall quality control of the steel cage, increases the maintenance cost after transportation, and it is difficult to ensure safety during the hoisting process. The steel cage hoisting frame consists of longitudinal I-beams and transverse I-beams. The longitudinal I-beam is the main load-bearing component, and the top is welded with a lifting lug for easy lifting. The bottom of the longitudinal I-beam is welded to the transverse I-beam through a rib plate to form a whole. The support rod is inserted into the steel cage, and the support rod and the transverse I-beam are connected by a sling. The support rod is directly in contact with the longitudinal steel bars of the steel cage, and the entire steel cage is lifted. The device is easy to process and easy to operate.

[0003] The existing prefabricated hollow slab beam reinforcement cage hoisting frame has the following defects when hoisting the hollow slab beam reinforcement cage: (1) Since the position of the transverse I-beam on the longitudinal I-beam is welded and fixed and cannot be adjusted, the support rod inserted into the reinforcement cage cannot be guaranteed to be directly below the transverse I-beam, resulting in the center of gravity shifting during hoisting, making the reinforcement cage hoisting unstable and tilted. For this reason, we propose a prefabricated hollow slab beam reinforcement cage hoisting frame. Utility Model Content

[0004] The purpose of the utility model is to provide a prefabricated hollow slab beam reinforcement cage hoisting frame to solve the problem proposed in the above background technology that the prefabricated hollow slab beam reinforcement cage hoisting frame is easily restricted by position and causes unstable hoisting and tilting.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a prefabricated hollow slab beam reinforcement cage lifting frame, comprising a longitudinal I-beam, a lifting lug and a transverse I-beam, the longitudinal I-beam being connected with a movable frame by sliding, the movable frame being inlaid with a screw barrel by rotation, the interior of the screw barrel being penetrated by a screw rod, and the screw rod and the screw barrel being connected by a thread, both ends of the screw rod being fixed with a mounting frame, the mounting frame being fixed on the surface of the longitudinal I-beam, and the transverse I-beam being fixed on the bottom surface of the movable frame.

[0006] Preferably, a spherical groove is provided on the surface of the movable frame, and a ball is embedded in the spherical groove.

[0007] Preferably, the cross section of the screw barrel is an I-shaped structure, and the longitudinal section of the screw barrel is a circular structure.

[0008] Preferably, the longitudinal section of the screw is a circular structure, and the central axes of the barrel and the screw coincide with each other.

[0009] Preferably, the outer walls of both ends of the screw barrel are sleeved with anti-slip sleeves.

[0010] Preferably, the mounting frame and the surface of the longitudinal I-beam are connected together with a rib plate, and the cross section of the rib plate is a triangular structure.

[0011] Preferably, a sling is provided on the transverse I-beam, and a support rod is provided at the bottom end of the sling.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) Through the designed movable frame, screw, screw barrel and mounting frame, the horizontal I-beam used for lifting the steel bars is fixed at the bottom of the movable frame, and the movable frame is slidably installed on the longitudinal I-beam. During lifting, the screw barrel is rotated, and the screw barrel and the screw are screwed to drive the movable frame to move and adjust the position. At the same time, the threaded connection has a self-locking feature, which locks the position of the movable frame and lifts the horizontal I-beam in the best lifting position to improve the lifting stability. The designed ball plays a lubricating role and reduces the friction resistance between the surface of the movable frame and the I-beam when the movable frame moves. The designed anti-slip sleeve is installed on the screw barrel to increase the friction coefficient of the screw barrel surface, which makes it easier to rotate the screw barrel. The designed rib plate reinforces the connection between the mounting frame and the longitudinal I-beam to prevent cracking. BRIEF DESCRIPTION OF THE DRAWINGS

The transverse I-beam 5 is fixed to the bottom surface of the movable frame 3. A spherical groove is provided on the surface of the movable frame 3, and a ball 11 is embedded in the spherical groove.
