Abstract
The invention discloses a lifting tool. The lifting tool comprises lifting hook assemblies. Each lifting hook assembly comprises a yoke plate, a beam and a lifting hook, wherein the lifting hook is arranged on the yoke plate, the yoke plate is arranged on the beam, and the lifting hook rotates by 360 degrees in the beam along the plumb line. A crane with the lifting tool comprises a sliding wheel set, a hanging beam, pin shafts and the lifting tool. The lifting hook assemblies are hung on the hanging beam and arranged on the hanging beam through the pin shafts. The hanging beam is connected with the sliding wheel set. The lifting hook assemblies transversely swing and rotate along the center line of the pin shafts and longitudinally swing and rotate along the axis center lines of the beams. The center lines of the lifting hooks, the axis center lines of the beams and the center lines of the pin shafts form a 90-degree angle in space. According to the lifting tool, hook heads of the lifting hooks rotate flexibly in the three-dimensional space, the safety accidents caused by slanting pulling and slanting hanging of the lifting hooks are avoided, the safety performance of the lifting tool is improved greatly, the service life of the lifting tool is prolonged, and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of hoisting crane, specifically a kind of suspender and use the hoisting crane of this suspender.
Background technology
The crane structure of general band drop in beam, when when about drop in beam, (transverse direction) is mobile, hook assembly can rotate the delayed movement of beat along the line of centers of the line of centers of crossbeam or bearing pin together with weight, when drop in beam is movable, braking time, weight and suspension hook or hook assembly are just without rotary freedom, because the direct rigidity of structural factor drives, the drop in beam of tens tons or tens tons forms powerful rigid shock, cause the beginning of fatigue failure of suspension hook, two-freedom drop in beam suspension hook lost efficacy in the past, and none is not caused by shear fatigue.
Summary of the invention
The object of the present invention is to provide a kind of suspender and use the hoisting crane of this suspender, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of suspender, comprise hook assembly, described hook assembly comprises yoke plate, crossbeam and suspension hook, and described suspension hook is arranged on yoke plate, and described yoke plate is arranged on crossbeam, described suspension hook in crossbeam along plumb bob vertical 360 ° rotation.
A kind of hoisting crane, comprise assembly pulley, drop in beam, bearing pin and described suspender, described drop in beam hangs hook assembly is set, described hook assembly is arranged on drop in beam by bearing pin, described drop in beam is connected with assembly pulley, described hook assembly is at the line of centers swing rotary laterally along bearing pin, at the shaft centre line swing rotary longitudinally along crossbeam, the three degree of freedom realizing suspension hook rotates, the line of centers of the line of centers of described suspension hook, the shaft centre line of crossbeam and bearing pin is in 90 ° mutually in space, realizes suspension hook and rotates freely three-dimensional.
As the further scheme of the present invention: described drop in beam hangs to arrange and organizes hook assembly more.
Compared with prior art, the invention has the beneficial effects as follows: by changing version crossbeam hanging suspension hook group, realize suspension hook gib head at three-dimensional flexible rotating, and then avoid suspension hook to hang generation safety misadventure because of askew skewing, substantially increase the safety performance of suspender, extend the service life of suspender, enhance productivity.
Accompanying drawing explanation
Fig. 1 is the front view of suspender and the hoisting crane using this suspender.
Fig. 2 is the left view of suspender and the hoisting crane using this suspender.
Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
Refer to Fig. 1-2, a kind of suspender, comprise hook assembly 7, described hook assembly 7 comprises yoke plate 4, crossbeam 5 and suspension hook 6, and described suspension hook 6 is arranged on yoke plate 4, and described yoke plate 4 is arranged on crossbeam 5, described suspension hook 6 in crossbeam 5 along plumb bob vertical 360 ° rotation.
A kind of hoisting crane using this suspender, comprise assembly pulley 1, drop in beam 2, bearing pin 3 and hook assembly 7, described hook assembly 7 comprises yoke plate 4, crossbeam 5 and suspension hook 6, described suspension hook 6 is arranged on yoke plate 4, described yoke plate 4 is arranged on crossbeam 5, described drop in beam 2 hangs many group hook assemblies 7, described hook assembly 7 is all arranged on drop in beam 2 by bearing pin 3, described drop in beam 2 is connected with assembly pulley 1, described suspension hook 6 in crossbeam 5 along plumb bob vertical 360 ° rotation, described hook assembly 7 is at the line of centers swing rotary laterally along bearing pin 3, at the shaft centre line swing rotary longitudinally along crossbeam 5, the three degree of freedom achieving suspension hook 6 rotates, ensure that suspension hook 6 only bears tensile stress, and without the perfect condition result of flexure stress, the line of centers of described suspension hook 6, the shaft centre line of crossbeam 5 and the line of centers of bearing pin 3 in 90 ° mutually in space, achieve suspension hook 6 to rotate freely three-dimensional, suspension hook fatigue life more than 3 times can be improved.
Principle of work of the present invention is: in shown in Fig. 1, definition left and right is laterally, front and back are longitudinally: when suspension beam of crane 2 sway, hook assembly 7 together with weight along with the sway of drop in beam 2, can along the line of centers beat of bearing pin 3, be rotate the potential energy raised by mobile kinetic transformation, the delayed mobile rigidity impulsive force reduced because drop in beam 2 sway produces of hook assembly 7 and weight, significantly decreases the lateral shear fatigue stress of suspension hook 6; When suspension beam of crane 2 moves forward and backward, weight together with hook assembly 7 along with the movable of drop in beam 2 can along the shaft centre line beat of crossbeam 5, be rotate the potential energy raised by mobile kinetic transformation, hook assembly 7 and the delayed mobile of weight reduce because of the movable rigidity impulsive force produced of drop in beam 2, equally significantly decrease the longitudinal shear fatigue stress of suspension hook 6; When suspension beam of crane 2 integral-rotation, because weight and hook assembly 7 longitudinally, laterally can rotate, can be all potential energy by mobile kinetic transformation, decrease rigid shock power, thus the significantly less synthesis fatigue stress of suspension hook 6.
The present invention is applicable to steel mill's mill, particularly often needs the busy workshop of handling sheet material and wire rod.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
