Detailed Description

The present invention will be described in further detail below by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not to be construed as limiting the present invention.

As shown in fig. 1, in the embodiment, a tail-sliding lifting lug 1 is fixedly installed at the position 10m away from the bottom of the tail part of a tubular pile 5, two main lifting lugs are fixedly installed at the upper part of the tubular pile 5, the tail-sliding lifting lug 1 is fixedly welded on a perpendicular bisector of a connecting line of the two main lifting lugs, and annular plates 11 are respectively and fixedly installed around lifting lug holes at two sides of the tail-sliding lifting lug 1, so that the rigidity of the tail-sliding lifting lug 1 at the lifting hole is enhanced, and the tail-sliding lifting lug 1 is prevented from being deformed due to pressure concentration in the lifting and turning processes; two reinforcing plates 12 are fixedly mounted on two sides of the tail sliding lifting lug 1 respectively, so that the capability of the tail sliding lifting lug 1 for resisting transverse deformation is enhanced, the effective contact with the pile body of the tubular pile 5 is enhanced, and the safety of the tail sliding lifting lug 1 in the hoisting process is improved. In this embodiment, the lug 1 is made of DH36 steel, the diameter of the lug hole is 170mm, the lug 1 is welded to the annular plate 11, the lug 1 is welded to the reinforcing plate 12, and the reinforcing plate 12 is welded to the tubular pile 5.

In this embodiment, the material of shackle 2 is alloy steel, shackle 2 is connected with swift current tail lug 1 and suspender 3 on the tubular pile 5, shackle 2 has shackle body 21 and horizontal round pin 22 of shackle, horizontal round pin 22 of shackle inserts in the lug hole of swift current tail lug 1, the head fixed mounting of horizontal round pin 22 of shackle has a pull ring 221, be connected through 6 safety links with anti-fall rope 23 on the pull ring 221, the other end of anti-fall rope 23 is fixed on shackle body 21 through 6 safety links, it loses to avoid breaking out horizontal round pin 22 after deviating from in shackle body 21 with horizontal round pin 22 of shackle. The pull ring 221 is connected with a pull rope 4 through a safety catch 6, so that a worker can conveniently pull the pull rope 4 at a safe position after completing the hoisting, and the shackle cross pin 22 is separated from the shackle body 21, thereby disconnecting the tubular pile 5 from the crane. In the embodiment, the anti-falling rope 23 is a steel wire rope, the pull rope 4 is a nylon rope with a steel wire core, the length of the pull rope 4 is about 20m, and the safety catch 6 is a galvanized double-safety catch.

In this embodiment, still be connected with suspender 3 on shackle 2, suspender 3 is the synthetic fiber suspender 3 of wide 10mm for connect shackle 2 and construction vessel auxiliary crane lifting hook, and synthetic fiber suspender 3's quality is lighter, makes things convenient for the workman to hang and gets.

In this embodiment, a groove is formed in the head of the shackle cross pin 22 along the axial direction of the shackle cross pin 22, and a slide bar is mounted in the groove and is capable of moving axially along the shackle cross pin 22 in the groove. The inner wall of the groove is provided with a clamping groove 222, the sliding rod is provided with a clamping block 226 matched with the clamping groove 222, and the clamping block 226 can move in the clamping groove 222 and is used for limiting the sliding rod to prevent the sliding rod from moving out of the groove. One end of the sliding rod, which is arranged in the groove, is connected with the bottom of the groove through an extension spring 225 and is used for retracting the sliding rod when the sliding rod is stopped to be pulled after the sliding rod is pulled out to the maximum displacement.

In this embodiment, a through hole is formed in the outer wall of the shackle transverse pin 22 near the tail of the groove, a vertical pin 223 is installed in the through hole, and a baffle 224 matched with the inner wall of the groove is fixedly installed at one end of the vertical pin 223 installed in the groove, so as to prevent the vertical pin 223 from falling from the through hole. A guide slope for the movement of the vertical pin 223 is also provided on the slide bar for allowing the vertical pin 223 to move outward of the shackle lateral pin 22 through the guide slope when the slide bar is retracted inward.

The use principle of the utility model is as follows: when the slide bar moves to the outermost position of the slot 222, the stopper 224 at the lower end of the vertical pin 223 is disengaged from the slide bar, and the vertical pin 223 falls into the groove of the shackle lateral pin 22 by gravity. At this time, the shackle cross pin 22 is inserted into the shackle body, the pull rope is loosened, the slide rod moves towards the inside of the groove under the action of the extension spring 225, the vertical pin 223 gradually moves towards the outer side of the shackle cross pin 22 under the action of the slide rod guide slope matched with the vertical pin 223 direction baffle 224, and finally the shackle cross pin 22 is locked, so that the problem that the shackle cross pin 22 falls off in the working process is solved. When the shackle needs to be disassembled, the pull rope is pulled to enable the slide rod to move outwards from the groove to the outermost position of the clamping groove 222, the baffle 224 at the lower end of the vertical pin 223 is not matched with the slide rod, the vertical pin 223 falls into the groove of the shackle transverse pin 22 under the action of gravity, the vertical pin 223 loses the function of locking the shackle transverse pin 22, the pull rope is continuously pulled, and the shackle transverse pin 22 is synchronously pulled out of the shackle under the limiting function of the clamping groove 222 on the groove of the shackle transverse pin 22 and the clamping block 226 on the slide rod. The slide bar will return to the shackle cross pin 22 recess under the influence of the tension spring 225 without further pulling of the pull cord.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
