Detailed Description

The embodiment of the application provides a pullover spare of overhead traveling crane clamp, has solved among the correlation technique overhead traveling crane clamp hoist and mount coil of strip time and has pressed against the technical problem that hurts to coil of strip inner circle.

In order to solve the technical problems, the general idea of the embodiment of the application is as follows:

the utility model provides a pullover spare of overhead traveling crane clamp, pullover spare install in the davit of overhead traveling crane clamp, and pullover spare is the arc face setting including being located the arc portion of top side, the last reason of arc portion, and overhead traveling crane clamp is used for the handling coil of strip, and arc portion is the face contact with coil of strip inner circle.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

Referring to fig. 1 to 3, the present embodiment provides a head set 10 of a crown block clamp 20, wherein the head set 10 is mounted on a boom 21 of the crown block clamp 20. The sleeve 10 includes an arc portion 110 located on the top side, the upper edge of the arc portion 110 is arranged in an arc surface, and the crown block clamp 20 is used for hoisting a steel coil. When the steel coil is hoisted on the suspension arm 21 of the crown block clamp 20, the upper edge arc surface of the arc part 110 is in surface contact with the inner ring of the steel coil, so that the adverse effect of damage to the inner ring of the steel coil caused by original line contact, particularly under the condition of extremely heavy weight of the steel coil, is improved, and the quality of cold-rolled products is favorably improved.

Preferably, the upper edge arc surface of the arc part 110 corresponds to a cross arc, and the diameter of the arc is equal to the diameter of the inner circle of the steel coil, so that the arc part 110 is in contact with the inner circle of the steel coil in a larger contact surface.

Optionally, the diameter of the upper edge arc of the arc-shaped portion 110 is smaller than the diameter of the inner ring of the steel coil, and the difference is controlled to be 0-10mm, so that the steel coil can be ensured to be in a surface contact state with the arc-shaped portion 110 after being loaded, and the adverse problem of damage to the steel coil can be solved. Wherein the diameter difference is 0-10mm, the diameter range based on the arc is 700-1536mm, and the difference is not easy to be too large, so as to avoid being unfavorable for improving the damage problem of the inner ring of the steel coil.

When the pullover 10 of the embodiment is used, the overhead traveling crane clamp 20 can be used for hoisting steel coils with different inner diameters, the pullover 10 corresponding to arcs with different diameters can be replaced, and the pullover can be mounted on the suspension arm 21.

Alternatively, the socket 10 may be adapted in such a way that only the arc portion 110 is directly bolted 400 to the upper side of the boom arm 21.

Alternatively, as shown in fig. 1 and 2, the head-sleeving part 10 can be configured as a cylinder and is mounted at the boom 21 of the crown block clamp 20 in a sleeving manner.

Alternatively, referring to fig. 1 and 2, the head unit 10 includes a barrel 100 and a bottom plate 200, the bottom plate 200 is connected to one axial end of the barrel 100, the other axial end of the barrel 100 is provided with an opening 120, and the top wall of the barrel 100 is an arc-shaped portion 110. The opening 120 provides access for the boom 21 to extend into the interior cavity of the headpiece 10, and the base 200 provides structural stability to the barrel 100.

Furthermore, the edge regions of the sleeve member 10 may be chamfered.

Optionally, referring to fig. 1 and 2, the pullover 10 further includes a pullover wheel 300, the pullover wheel 300 is rotatably mounted on the vertical outer surface of the barrel 100, and a portion of the pullover wheel 300 extends out of the geometric range of the barrel 100, specifically, out of the bottom side of the barrel 100. When the steel coil is loaded on the crane clamp 20, a stretching process is involved, the suspension arms 21 on the two sides are firstly away from each other and then close to each other, and the original sliding friction is converted into rolling friction through the sleeve head wheel 300, so that the inner ring of the steel coil is prevented from being scratched.

The wheel 300 may be made of polyurethane.

Alternatively, the headpiece 10 is made of polyurethane.

Optionally, the socket 10 is connected with the boom 21 by a bolt 400, so that the socket 10 is convenient to disassemble and assemble.

Optionally, the socket 10 is provided with a countersunk bolt hole, and the socket 10 is mounted to the boom 21 by means of the countersunk bolt cooperating with the countersunk bolt hole.

The embodiment further provides a crown block clamp 20, which comprises the sleeve head part 10 of the crown block clamp 20, and the problem of damage to the steel coil when the crown block clamps the liver to lift the steel coil is solved.
