Description

Technical Field

[0001] The utility model relates to the technical field of slings, in particular to a tower crane standard section sling tooling used in conjunction with a hook. Background Art

[0002] The tower crane standard section introduction hoist is one of the important components of the tower crane. The standard section is introduced into the climbing frame and cooperates with the climbing frame to realize the jacking operation of the entire tower crane. The tower crane standard section hoist tooling used with the hook is a tooling equipment designed for tower cranes. It is used to cooperate with the hook to carry out the hoisting operation of the standard section. The rationality and efficiency of the hoisting structure determine whether the jacking operation can be carried out smoothly. However, the existing hoisting tools still have defects and deficiencies to a certain extent that need to be improved:

[0003] For example, the application number is CN201420761250.2: a tower crane standard section combined lifting device, including a hook I, a hook II, and a rib plate, the hook I is in an "L" shape, one end of the hook I is bent into a lifting ring, and the other end is a straight edge, the rib plate is located at the angle of the hook I to connect the two sides of the hook I, one end of the hook II is bent into an upper lifting ring, and the other end is bent into a lower lifting ring, the lifting ring and the upper lifting ring are at the same height, the straight edge of the hook I can be inserted into the lower lifting ring of the hook II, the hook I The angle formed by the two sides is less than 90°, the inner diameter of the lower lifting ring is equal to the diameter of the straight side, the hook of the accumulation and release conveying system is used to hook the lifting ring and the upper lifting ring at the same time, and the straight side hangs the standard section by passing through the standard section connecting sleeve on the main chord of the standard section. The standard section combined sling composed of hook I, hook II and rib plate has a simple structure and is easy to use. The sling not only has a strong carrying capacity and good safety performance, but also does not block the workpiece when in use, and does not require patching and spraying, which saves labor costs and improves production efficiency.

[0004] The slings in the above documents directly connect the hook head with the lifting point on the sling through ropes. There is a lifting point corresponding to the width of the hook head at the center of the sling structure. The hook head pulls the sling in the vertical direction through the rope. It is only applicable to the working condition where the hook head range is larger than the distance between the lifting points on the sling. When the center distance between the lifting points on the sling is larger than the hook head size, the sling rigging is tilted, which will generate horizontal tension and cause unstable lifting;

[0005] The moving position of the hoist in the above-mentioned document cannot be located. When the hoist is working, due to external factors such as wind force, the hoist may tilt when hoisting the standard section, posing a safety hazard.

[0006] Therefore, we propose a tower crane standard section lifting tooling used in conjunction with a hook to solve the above-mentioned problems. Utility Model Content

[0037] The carrier 3 forms a traction structure with the winder 7 through a main pull rope 12 , and the main pull rope 12 is fixedly connected to one end of the stabilizing frame 14 that is fixedly connected to the carrier 3 .

[0038] The staff can start the winder 7 to make the winder 7 wind up the main pull rope 12. At this time, the main pull rope 12 is subjected to tension and synchronously pulls the carrier 3 upward under the action of the main pulley 10, thereby completing the lifting of the sling.
