Description
Technical Field
The utility model relates to the field of steel structure construction, in particular to a crane beam circulating hoisting sling.
Background
At present, the assembled building is greatly developed in China, and the assembled factory building is widely applied. The assembled factory building adopts a bent system and a portal steel frame system, and if the factory building has a hoisting function requirement, a bent system structure is adopted, and a crane beam adopts a precast reinforced concrete crane beam or a steel crane beam. When the span of a factory building is large or the lifting capacity of a crane is large, steel crane beams are mostly adopted.
The steel crane beam is generally installed at present through the lifting lug, the lifting lug is welded with the upper flange of the steel crane beam in a penetration way, and the steel crane Liang Chongliang is large, so that the lifting lug is large in specification, the parent metal is easily damaged through flame cutting in the dismantling process, and the flatness of the upper flange cannot be guaranteed.
Through the search, CN 202609776U-a crane beam special lifting appliance, CN 203143924U-a lifting appliance for lifting a steel crane beam and CN 216141125U-a crane beam lifting special lifting appliance are all lifting appliance grooving, and the upper flange is clamped by a groove for lifting, so that the parent metal is damaged.

Detailed Description
As shown in fig. 1-4: a crane beam circulating hoisting sling comprises a base, lifting lugs and a high-strength bolt; the lifting lugs are vertically welded in the middle of the base, four connecting holes are formed in the base, and the four connecting holes are respectively formed in two sides of the lifting lugs; the base is bolted with the upper flange of the crane beam through a high-strength bolt, and the high-strength bolt adopts a large hexagon head bolt; a sand spraying layer is arranged on the friction surface of the base and the upper surface of the upper flange of the crane beam; the lifting lug and the base are welded by partial penetration or full penetration.
The application method of the utility model is as follows:
step one: the base 1 of the lifting appliance 3 is provided with a hole, the diameter of the hole=the diameter of the high-strength bolt 4+1.5mm, and the high-strength bolt is a high-strength large hexagon head bolt connection pair.
Step two: the lifting lug 2 of the lifting appliance 3 and the base 1 are welded in a partially penetration way or a full penetration way, nondestructive detection is carried out after welding, and penetration detection (PT) or ultrasonic detection (UT) can be adopted to ensure the quality of welding seams and the lifting safety. The lifting appliance 3 is analyzed by finite element software, and the strength and deformation value of the lifting appliance 3 are required to meet the related specification requirements.
Step three: the original track of the upper flange of the steel crane beam 5 is connected with a preformed hole, the lifting appliance 3 is bolted with the upper flange of the steel crane beam 5 through a high-strength bolt 4, the friction surface of the upper surfaces of the base 1 and the upper flange of the steel crane beam 5 is subjected to sand blasting treatment, and the anti-slip coefficient of the friction surface meets the related standard requirements.
Step four: after the steel crane beam 5 is lifted, the high-strength bolts 4 are loosened, the lifting appliance 3 is removed, namely the lifting appliance 3 is removed, the lifting appliance 3 is inspected regularly, and the high-strength bolts 4 cannot be reused.
Step five: repeating the first step to the fourth step, and circularly using the lifting tool 3 for lifting.
