The first embodiment is as follows: referring to fig. 1, for the utility model discloses a coil of strip lifting hook with adjustable, including rings 1, crossbeam 2 and hook body 3, rings 1 is located 2 top surfaces of crossbeam central authorities to with 2 integrated into one piece of crossbeam. Hook body 3 has two and sets up at crossbeam 2 both ends, sliding connection sliding assembly 5 on crossbeam 2, and hook body 3 passes through hoist chain 4 to be connected on sliding assembly 5, and sliding assembly 5 adjusts the distance between two lifting hooks to adapt to the coil of strip 14 of the different width of handling.

Referring to fig. 2, the sliding assembly 5 includes a sliding groove 52, a sliding rod 53 and a sliding block 51 sliding on the sliding rod 53, wherein two sliding grooves 52 horizontally penetrating are located at the center of the cross beam 2 and extend along the length direction thereof, and the ends of the two sliding grooves 52 are not communicated. The horizontal sliding rod 53 is fixed to the center of both side walls of the sliding groove 52 in the horizontal direction, and the sliding rod 53 is slightly close to the lower surface of the groove 112. The slide block 51 is fitted to the cross member 2, the slide block 51 has a slide passage 512 through which the slide rod 53 passes in a slide portion 511 penetrating the slide groove 52, and the slide block 51 slides on the slide rod 53. The two sliding blocks 51 slide in the two sliding grooves 52 respectively, the sliding block 51 on one side does not slide to the other side of the beam 2, and a pushing block 513 is arranged above the sliding part 511.

The cross beam 2 is provided with a pushing device 6 for pushing the sliding block 51 to move, and the pushing device 6 comprises a pushing rod 61 with threads. Referring to fig. 3, a push rod 61 horizontally penetrates through a side wall of the cross beam 2 and extends into the sliding groove 52, the cross beam 2 penetrated by the push rod 61 is in threaded connection with the push rod 61, the push rod 61 is located above the sliding rod 53, one end of the push rod 61 is provided with a cylindrical bump 611 with a diameter larger than that of a rod body of the push rod 61, the surface of the bump 611 is smooth, the bump 611 is inserted into the push block 513, a cavity 514 for the bump 611 to rotate inside is formed in the push block 513, a handle 62 is fixed at the other end exposed out of the cross beam 2, the push rod 61 is rotated, the push rod 61 rotates in the push block 513, and the push rod 61 continuously pushes the sliding block 51 forwards so that the. When the push lever 61 stops rotating, the push block 513 also stops moving. Referring to fig. 4, the upper surface of the beam 2 has a semi-cylindrical flange 7 extending along the length thereof, the flange 7 has a smooth surface, the sliding block 51 has a semi-circular groove 8 corresponding to the shape of the flange 7 on the surface opposite to the upper surface of the beam 2, and the flange 7 is recessed in the semi-circular groove 8, so that the sliding block 51 is stable and reduces sliding friction when sliding.

Referring to fig. 2, the side of the beam 2 above the sliding slot 52 has a scale 9 extending along its length, and the side wall of the sliding block 51 has a pointer 10 pointing to the scale 9, and since the sliding block 51 is positioned by the pushing rod 61, the moving positions of the two sliding blocks 51 are uncertain, and if the two sliding blocks 51 are not symmetrical, the hook will tilt when the steel coil 14 is lifted. Therefore, by observing the value on the scale 9, the two sliding blocks 51 are always kept sliding equidistantly, so that the hook is balanced.

Referring to fig. 1, the bottom surface of the slide block 51 is fixedly connected with the hoist chain 4, and the hoist chain 4 is fixed on the hook body 3. The two hook bodies 3 are inserted into the centers of both end surfaces of the steel coil 14 to lift the steel coil 14 (see fig. 6). Referring to fig. 5, the buffer 11 is disposed at the vertical section of the hook body 3, and when the steel coil 14 is loaded on the hook, the two end faces of the steel coil 14 collide with the hook body 3 or incline, so that the buffer 11 reduces the damage to the end faces of the steel coil 14. Buffer 11 includes buffer board 111, and buffer board 111 is located the vertical section side of hook body 3, and the one side that two buffer boards 111 deviate from mutually is fixed with two springs 113, and the vertical section of hook body 3 has and supplies the recess 112 that buffer board 111 sinks into, and the spring 113 other end is fixed on recess 112 inner end inner wall, makes buffer board 111 can slight motion on the horizontal direction, cushions the impact to coil of strip 14.

The implementation principle of the embodiment is as follows: the crane lifts the suspension ring 1, rotates the handle 62 according to the width of the steel coil 14, pushes the sliding blocks 51, the sliding blocks 51 slide on the sliding rods 53, and observes the graduated scale 9 to enable the sliding distances of the two sliding blocks 51 to be consistent and to be symmetrical about the suspension ring 1.

The two hook bodies 3 are respectively inserted into the centers of the two end faces of the steel coil 14, the lifting hook is lifted, and the steel coil 14 is transferred and placed down, and if the steel coil 14 inclines, the buffer plate 111 abuts against the end face of the steel coil 14 and slightly shakes.

Example two: referring to fig. 7 and 8, for the utility model discloses a coil of strip lifting hook with adjustable, with the difference of embodiment one, 4 tops of lifting chain that are connected with crossbeam 2 are couple 12, and there is shackle 13 crossbeam 2 bottom surface, and couple 12 is hung on shackle 13, can realize dismantling of hook body 3. The hanging ring 1 is a chain and is fixed on the top surface of the cross beam 2.

When the steel coil 14 is narrow in width and only one hook body 3 is used for lifting the steel coil 14, the hook 12 on one hook body 3 is detached from the hook ring 13, the other hook body 3 slides to the end part of the sliding groove 52 close to the center of the cross beam 2, when the steel coil 14 is hung on the hook body 3, the lifting ring 1 is hung on a crane, the gravity center of the whole lifting hook is automatically found, the cross beam 2 can incline, but the lifting chain 4 can still keep a vertical state due to the fact that the hook 12 is hung on the hook ring 13, and the hook body 3 and the steel coil 14 keep a vertical stable state.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
