Embodiment Construction
[0009] Such as figure 1 As shown, the hoisting device for the large-scale cantilever beam structure load test of the present invention includes two parts, one part is a plate frame structure 9 with round holes on it for hanging slings and gibs; the other part is a bolt locking assembly 1 . Specifically, the upper end of the plate frame 9 is provided with an annular closed connection port A for hooking the top drive, and the lower end is provided with a connection port B for hooking up the suspension rope. The above-mentioned bolt locking assembly 1 is arranged at the notch end of the connection port B. Wherein, the bolt locking assembly 1 includes two pairs of screw rods / nuts located at the upper and lower ends of the opening of the connection port B, and a locking plate between the two pairs of screw rods / nuts. In order to ensure the strength of the plate frame, reinforcing flat irons 2 are respectively fixed on both sides of the plate body of the plate frame 9 .

The invention discloses a large cantilever beam structure loading experiment lifting device which comprises a rectangle grillage and a bolt locking module, wherein, an annular sealing connecting opening which is used to hang a top driving is arranged on the upper end of the grillage. A connecting opening which is used to hang a sling is arranged on the lower end of the grillage. The bolt locking module is arranged on the breach end of the connecting opening on the lower end. The bolt locking module comprises two pairs of bolts / nuts and a locking plate between two pairs of bolts / nuts, wherein, two pairs of bolts / nuts are fixed on the grillage and are positioned on the upper end and the lower end of the breach. Two sides of the body of the grillage are respectively fixed with a reinforcing black iron. The invention is specially used for the large cantilever beam structure loading experiment. The invention has the characteristics of lightness, conciseness and small size; therefore, the requirement of large loading lifting space limiting in the cantilever beam loading experiment can be satisfied. The effect is very prominent by the practical use.
Description
technical field [0001] The invention relates to a hoisting device used for the load test of a large cantilever beam structure, more specifically, to a hoisting special connecting tool with a load of 700-1000 tons. Background technique [0002] The large-scale cantilever beam structural load test is mainly aimed at testing the load capacity of large-load cantilever beams in shipbuilding, offshore platforms and construction fields, so as to ensure safe and reliable actual use. Usually, when carrying out the load test of a large cantilever beam structure, its load weight can reach 700-800 tons, and even the design load can reach 1000 tons. To lift such a large load, in the case of limited operating space for the cantilever beam, it is necessary to design a special lifting device for the cantilever beam load test. Especially for offshore platforms, due to the limited space in the center of the turntable and the moon pool, special devices must be designed to complete the structu...
