Abstract
The invention discloses a standard joint combined type hanger of a tower crane. The standard joint combined type hanger comprises a lifting hook I, a lifting hook II and a rib plate, wherein the lifting hook I is L-shaped; one end of the lifting hook I is bent into a lifting ring and the other end of the lifting hook I is a straight edge; the rib plate is located at the included angle of the lifting hook I and is connected with the two edges of the lifting hook I; one end of the lifting hook II is bent to form an upper lifting ring and the other end of the lifting hook II is bent to form a lower lifting ring; the lower lifting ring and the upper lifting ring are at the same height; and the straight edge of the lifting hook can be inserted into the lower lifting ring. The standard joint combined type hanger of the tower crane is simple in structure and convenient to operate; a workpiece is not shielded in a use process, and supplemented spraying is not required; and the appearance quality of a standard joint is improved and the safety performance is high.
Description
Technical field
The present invention relates to a kind of Combined type sling, particularly a kind of tower machine standard knot Combined type sling.
Background technology
During the application of tower machine, need be hanging on aerial free parking type delivery system walking dolly by framing member by suspender, framing member is delivered to each station by walking dolly again.Standard knot is tower machine important component part, the main chain sling mode that adopts carries out hanging standard knot at present, first chain is wound on main chord of standard section, and then by chain suspension on walking dolly, this kind of suspending way exists drawback, the position spray that chain is wound around is less than paint, need carry out making up a deficiency spraying, not only use inconvenience, add labor strength and productive costs, also have a strong impact on product design.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of structure simple, easy to operate, not blocking workpiece in use procedure, without the need to making up a deficiency spraying, improving standard knot presentation quality and the high tower machine standard knot Combined type sling of safety performance.
To achieve these goals, the technical solution used in the present invention is: a kind of tower machine standard knot Combined type sling, comprise suspension hook I, suspension hook II, gusset, suspension hook I is L-shaped, and one end of suspension hook I bends to suspension ring, the other end is straight flange, gusset is positioned at the both sides of the angle connecting shackle I of suspension hook I, and suspension hook II one end bends to upper lift ring, and the other end bends to lower lift ring, suspension ring and upper lift ring are in sustained height, and the straight flange of suspension hook I can insert in the lower lift ring of suspension hook II.
Further, the angle that the both sides of suspension hook I form is less than 90 °;
Further, the internal diameter of lower lift ring equals the diameter of straight flange;
Further, free parking type delivery system suspension hook is used for catching on suspension ring and upper lift ring simultaneously;
Further, straight flange is used for hanging standard knot;
Further, straight flange is by hanging standard knot through the standard knot adapter sleeve on main chord of standard section.
The invention has the beneficial effects as follows: the standard knot Combined type sling be made up of suspension hook I, suspension hook II, gusset, structure is simple, easy to use, and suspender not only load-carrying capacity is comparatively strong and high safety performance is good, workpiece is not blocked during use, without the need to making up a deficiency spraying, saving labour turnover, enhancing productivity.

Detailed description of the invention
Below in conjunction with
accompanying drawingthe invention will be further described.
as Fig. 1shown in-4, a kind of tower machine standard knot Combined type sling, comprise suspension hook I1, suspension hook II2, gusset 3, suspension hook I1 is L-shaped, one end of suspension hook I1 bends to suspension ring 1-1, the other end is straight flange 1-2, gusset 3 is positioned at the both sides of the angle connecting shackle I1 of suspension hook I1, suspension hook II2 one end bends to upper lift ring 2-1, the other end bends to lower lift ring 2-2, suspension ring 1-1 and upper lift ring 2-1 is in sustained height, the straight flange 1-2 of suspension hook I1 can insert in the lower lift ring 2-2 of suspension hook II2, this tower machine standard knot Combined type sling structure is simple, suspension hook I1, suspension hook II2 is removable, the angle that gusset 3 is positioned at suspension hook I1 strengthens suspender load-carrying capacity, suspension hook II2 plays lock hook effect, further enhancing safety performance.
The angle that the both sides of described suspension hook I1 form is less than the steadiness that 90 ° strengthen suspension hook I1 further.
The internal diameter of described lower lift ring 2-2 equals the diameter of straight flange 1-2, and straight flange 1-2 can to insert in suspension ring 2-2 and not interspace, and enhances safety performance.
Described free parking type delivery system suspension hook 5 is used for catching on suspension ring 1-1 and upper lift ring 2-1 simultaneously, strengthens the load-carrying capacity of suspender further.
Described straight flange 1-2 is used for hanging standard knot.
Described straight flange 1-2 is by hanging standard knot through the standard knot adapter sleeve 4-1 on main chord of standard section 4.During use, the straight flange 1-2 of suspension hook I1 is inserted in standard knot adapter sleeve 4-1, the lower lift ring 2-2 of suspension hook II2 is enclosed within straight flange 1-2, upper lift ring 2-1 and suspension ring keep sustained height, during by accumulating, standard knot is hung on aerial free parking type delivery system walking dolly by delivery system suspension hook 5, under the effect of standard knot gravity and free parking type delivery system suspension hook 5, suspension hook II2 and suspension hook I1 is fully seated, avoids unhook situation occurs in operational process.
