Detailed ways

The technical solutions of the present utility model will be further described in detail below in conjunction with the specific embodiments, but do not constitute any limitation to the present utility model.

Referring to FIGS. 1 to 7 , a hanger of the present invention includes a hook 1 and a base 2 that is adapted to the top surface of the part 13 to be lifted. The hook 1 is symmetrically installed at both ends of the base 2 , and the middle part of the hook 1 is rotatably connected with the end of the base 2, the hook 1 is provided with a clamping block 3, the clamping block 3 is provided with a clamping slot 31, and the base 2 is also rotatably connected with a clamping slot 31 that can be clamped inside the clamp 4. When lifting the part, the bottom surface of the base 2 is pressed against the top surface of the part 13 to be lifted, the hooks 1 at both ends of the base 2 are clamped on the bottom surface of the part, and the hoisting tool is lifted by the crane 14 to lift the part. When the empty spreader is hoisted, the clamping rod 4 rotatably connected with the base 2 is clamped in the clamping slot 31 on the clamping block 3, so that the hook 1 is kept in an open state, avoiding the need for the spreader to be hoisted onto the part. The hook 1 interferes with the lifting position of the part.

Preferably, two mounting plates 5 are symmetrically arranged at both ends of the base 2, the hook 1 is eccentrically hinged with the two mounting plates 5 on the base 2 through the rotating shaft 6, and the center of gravity of the hook 1 is located inside the center of its rotation. , so that when the spreader is in a free state, the hook 1 is in an open state under the action of gravity.

Preferably, a fixing plate 7 is provided on the base 2 inside the mounting plate 5 , and the clamping rod 4 is hingedly connected to the fixing plate 7 through a connecting rod 8 .

Preferably, the rotation trajectory of the clamping rod 4 intersects with the rotation trajectory of the clamping slot 31 , and the intersection point of their rotation trajectories is located above the inner side of the fixing plate 7 . When the crane 14 is used to lift the empty spreader, the rotation trajectories of the hook 1 and the clamping rod 4 are different, and the clamping rod 4 and the lower side of the clamping slot 31 are stuck and cannot rotate, so that the hook 1 can be in an open state .

Preferably, the clamping slot 31 is a conical opening, so that the clamping rod 4 can be easily clamped in the clamping slot 31 .

Preferably, one end of the hook 1 on the outer side of the base 2 is U-shaped, so that when the part is hoisted, the bottom of the hook 1 can be clamped on the bottom surface of the part.

Preferably, the hook 1 includes a first side plate 9, a second side plate 10, and a first middle plate 11 and a second middle plate 12 connecting the two. The first side plate 9 is provided with a hoisting hole 9a, the fixing plate 7 is located between the first side plate 9 and the second side plate 10, and the clamping block 3 is installed on the first side plate 9, so that when the empty spreader is hoisted, , the acting forces of the crane 14 and the clamping rod 4 both act on the first side plate 9, which avoids the phenomenon of instability caused by the dispersion of the force when the empty spreader is hoisted.

Preferably, the length of the base 2 is greater than the length of the part 13 to be lifted, which can effectively protect the machined surface of the part 13 to be lifted.

Preferably, the base 2 is provided with a weight reduction groove 2a, which can reduce the weight of the spreader.

When the above-mentioned spreader is in use, the hook on the crane 14 is hooked into the lifting hole 9a. At this time, the hook 1 is in an open state under the action of gravity, and the clamping rod 4 is manually rotated to the clamping slot 31 of the clamping block 3. Then, the hoisting crane 14 lifts the spreader, and the crane 14 lifts it from the storage place to the part 13 to be lifted. At this time, the clamping rod 4 is clamped in the clamping slot 31 on the clamping block 3, and the hook 1 remains open state. Lift the spreader to the top of the part 13 to be lifted, then put the spreader on the top surface of the part, loosen the hook of the crane 14, manually rotate the clamping rod 4 to leave the clamping slot 31 on the clamping block 3, and then lift the crane 14 At this time, the hook 1 is in a hooked state under the pulling force of the hook of the crane 14. Continue to lift the hook of the crane 14 until the connecting parts of the spreader are hoisted together for hoisting. After the hoisting to the destination, lower the hook of the crane 14 to In the relaxed state, turn the clamping rod 4 into the clamping slot 31 on the clamping block 3, and then lift the crane 14 to hoist the spreader. At this time, the clamping rod 4 is clamped in the clamping groove 31 of the clamping block 3, and the hook 1 Keep the open state and continue to lift the crane 14 so that the spreader leaves the part to complete the lifting process. When the hanger is hoisting the parts, the base 2 is pressed against the top surface of the part, and the clamping position of the hook 1 is the bottom surface of the part, which can effectively avoid damage to the parts whose top surface is the machined surface. When the spreader is hoisted, the hook 1 can be kept in an open state, which effectively avoids the interference between the hook 1 and the hoisting position of the part when the spreader is hoisted to the part.

The above are only preferred embodiments of the present invention, and any modifications, equivalent replacements and improvements made within the spirit and principle scope of the present invention should be included within the protection scope of the present invention.
