Description

Lifting lug device for jacket pocket crane Technical Field The utility model relates to the field of jacket hoisting, in particular to a lifting lug device for jacket pocket hoisting. Background The installation technical requirement of the jacket in the construction of the offshore wind farm is high, and the jacket is a key factor in the construction process of the wind farm. The weight of the jacket structure in the deepwater area is more than kiloton, the weight of the shackle used for hoisting is correspondingly increased, and the shackle and the lifting lug are more difficult to install when the jacket is hoisted by a crane ship due to the comprehensive influence of factors such as weather, waves, water flow and tides, so that the hoisting efficiency of the jacket can be effectively improved by selecting a proper installation mode. For the construction conditions of severe sea conditions, limited mechanical equipment and high labor cost, the lifting mode can be used for lifting in a mode of hanging the shackle and the pocket crane, wherein the shackle is long in construction period, poor in sea condition adaptation capability, high in labor cost and low in safety coefficient, and the construction period of the project is seriously influenced. In order to improve the offshore construction efficiency, accelerate the construction progress and ensure the construction safety, the lifting lug device of the jacket pocket crane is urgently needed to be developed for lifting. Disclosure of utility model The utility model mainly aims to provide a lifting lug device for a jacket pocket crane, which adopts a pocket crane mode, is higher than the traditional process, has a simple using method and safer operation, and solves the problem of safety risk caused by shaking of a lifting hook when a person hangs a lifting rigging during the traditional jacket lifting. In order to solve the technical problems, the lifting lug device for the jacket pocket crane comprises a jacket, wherein the jacket is provided with a plurality of main legs, one side of each main leg is provided with a plurality of main shafts, one end of each main shaft is provided with an outer ear plate and an inner ear plate, and the outer circle of the other side of each main shaft is uniformly provided with a plurality of stiffening plates; A gap is arranged between the outer ear plate and the inner ear plate, a plurality of penetrating pin holes are formed in the surface of the outer ear plate, a plurality of penetrating threaded holes are formed in the surface of the inner ear plate, and the pin holes correspond to the threaded holes one by one. In the preferred scheme, be equipped with detachable round pin axle between outer ear board and the inner ear board. In the preferred scheme, one end of the pin shaft is provided with a threaded part, and the threaded part is used for being meshed with the threaded hole. In the preferred scheme, the main legs are arranged in A, B, C, D directions of the jacket and are arranged in square vertex directions. In the preferred scheme, the main shafts are arranged on two sides of the main legs, and an included angle F is formed between the main shafts on two sides. In a preferred embodiment, the degree of the included angle F is 120-150 degrees. In the preferred scheme, a hanging strip is further arranged in a gap between the outer ear plate and the inner ear plate, and finally the hanging strip is gathered at the E point on the jacket; the pin shaft is used for pressing the hanging belt between the outer ear plate and the inner ear plate to prevent unhooking. In the preferred scheme, the stiffening plate is welded with the main leg. The utility model provides a lifting lug device for a jacket pocket crane, which has the following beneficial effects: 1. The structure is simple, the device is manufactured in factories, the processing precision is high, and the work efficiency of installing the hanging belt is higher than that of the traditional process, and the use method is simple; 2. The problem of finished product protection during jacket installation is fully solved, and the hanging strip cannot damage the transitional section platform structure and corrosion resistance of the jacket under the condition of poor sea conditions; 3. the jacket hook is safer to operate, compared with the existing hanging and shackle process, the jacket hook adopts a pocket hanging mode, and the safety risk caused by shaking of the hanging hook when a constructor hangs a hanging rigging is greatly reduced.
