Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 4, the utility model provides a lifting hook buffer, including barrel 1, barrel 1 is cylindrical structure.

The bottom of barrel 1 is connected with the arc piece 3 that two symmetries set up, the radian of arc piece 3 and the lateral wall radian looks adaptation of barrel 1.

All be provided with the enhancement layer 2 between the lateral wall of two arcs piece 3 and barrel 1, the thickness of enhancement layer 2 is less than the thickness of arc piece 3. Specifically, the reinforcing layer 2 is welded on the cylinder body 1, then the arc-shaped sheet 3 is welded on the reinforcing layer 2, and when the arc-shaped sheet 3 is broken, deformed and the like and needs to be replaced, the reinforcing layer 2 can be directly cut, so that the cylinder body 1 can be protected from being cut and damaged, the cylinder body can be recycled, and the cost is reduced; meanwhile, the thickness of the reinforcing layer 2 is smaller than that of the arc-shaped sheet 3, so that the weight of the whole hoisting buffer is reduced, and the connection strength of the arc-shaped sheet 3 and the cylinder body 1 is enhanced.

The lower parts of the two arc-shaped pieces 3 are connected with connecting devices 4, each connecting device 4 comprises a U-shaped connecting base body 40, and the tops of two supporting legs of each U-shaped connecting base body 40 are connected with connecting rings 41 respectively. The U-shaped connection base 40 clamps the arc-shaped sheet 3 from the bottom of the arc-shaped sheet 3, and is overlapped with the holes at the corresponding positions on the arc-shaped sheet 3 through the annular holes on the two connection rings 41 and fixedly connected through connecting pieces such as bolts.

Each connecting device 4 is connected with a chain hanging ring 5, specifically, a U-shaped groove of the U-shaped connecting base body 40 of each connecting device 4 is connected with the chain hanging ring 5, and the chain hanging ring 5 is connected with a bar chain 6. The chain hanging ring 5 comprises an upper half ring 51 and a lower half ring 52, and the upper half ring 51 is connected with the lower half ring 52 through a pin shaft.

The upper half ring 51 is connected with the U-shaped connecting base body 40, and the lower half ring 52 is connected with the bar chain 6.

Two ends of the bar chain 6 are respectively connected to the connecting devices 4 connected to the lower parts of the two arc-shaped pieces 3 and used for hoisting the bars 7, so that the auxiliary hoisting effect is effectively achieved, and the problem that the long bars are easy to bend and deform at high temperature in the processing process is solved.

The welding of the top of barrel 1 has footstock 8, for the stability of being connected of reinforcing footstock 8 and barrel 1, and for preventing that footstock 8 warp, sets up four at least strengthening ribs 9, and preferred strengthening rib is 1/4 circle structure at the equal angle of the junction of the bottom outward flange of footstock 8 and barrel 1.
