Abstract

The utility model relates to a sling with a self-hanging and self-unloading hanging shear, which can adopt the gravity and the effect of the component to realize the self-hanging, hoisting, loading and self-unloading of the component through the hook lifting and falling operation of the crane operator. The appearance of the sling is in the scissors shape. The sling can be used for hoisting I-shaped or T-shaped components, and improve the safety and efficiency of the component hoisting operation. The sling comprises a shear arm (1) with a slide groove, a shear arm (2) with a positioning groove, a central shaft (3), a self-locking device (7) arranged on a hanging shear (1), and a shift lever (6) arranged on a hanging shear (2). The utility model adopts the relative rotation of the shear arms to change the length of the self-locking device, so that the shear arms maintain the relative movement restricted or unrestricted, thereby achieving the self-hanging and self-unloading purpose.

Description

A kind ofly hang and cut from hanging self lighting type

Technical field

The utility model belongs to a kind of lifting device, has the function from extension, self-unloading.

Background technology

At present, the structure manufacture of the fabrication and installation of steel structure, building field install and the loading-unloading vehicle process of goods transport in, often to use the suspender that is similar to scissors as I shape or T type member, be commonly called as " hang and cut ".This suspender is practical convenience under the lower situation of primary structural component or sling height.When running into heavier member because suspender stressed bigger, hang to cut and correspondingly also will do greatlyyer, hang cut and pluck when cutting more painstaking; And when sling height was higher, the people must climb up the member operation, even also there is certain danger in little suspender, if suspender is more dangerous just bigger, and efficient is also low.Become a safe dead angle of above industry.

Summary of the invention

In order to overcome the used above shortcoming of cutting of hanging at present, the utility model provide a kind of can be by the effect of gravity own and member, move the instrument that carries out the hanging certainly of member, lifting, off the hook and self-unloading work by craneman's the off the hook that rises.

A kind ofly hang and cut from hanging self lighting type, outer image scissors, two arm front ends respectively have an inside crotch; It is cutting arm (1), have cutting arm (2), center shaft (3), be installed in the self-locking device of cutting on the arm (1) (7) and be installed in the driving lever (6) cut on the arm (2) and constituting of positioning groove by the band deep-slotted chip breaker; It is characterized in that: the end that driving lever (6) is gone up the band inclined-plane is positioned at the deep-slotted chip breaker of cutting arm (1), can with inclined-plane, the movable termination slide relative that is installed in the self-locking device of cutting on the arm (1) (7).

The technical scheme that its technical matters that solves the utility model adopts is: outside hanging the middle pivot of cutting, one cut on the arm driving lever is installed, another is cut a self-locking device is installed on the arm, make to hang to cut and before dropping to member, be in open configuration, when after cutting the inboard contact member of arm, continuing to fall, because the upwards application force of gravity of self and member, make two to cut arm and open certain angle again, remove self-locking state; Cut when being sling when hanging, owing to draw on the lifting rope and hang the effect of cutting self gravitation, cut that arm just draws in to the inside and member clamped and hook, thereby realized hanging certainly the purpose of cutting, lifting by crane; After member is winched to the desired location, along with hanging falling, loosen and continuing descending of cutting, when after cutting the inboard contact member of arm, continuing to fall, because the upwards application force of gravity of self and member, make two to cut arm and open certain angle again, cut when being sling once more when hanging, cutting arm just draws in to the inside, cut when being continued to sling distance member certain altitude when hanging, owing to draw, hang the effect of cutting self gravitation and self-locking device on the lifting rope, enter self-locking state once more, cut and be in open configuration thereby make to hang, and ready for hang member next time.

The beneficial effects of the utility model are to increase work efficiency, to reduce the generation of worker's labour intensity, minimizing safety misadventure.

The specific embodiment

Cut arm (1,2) and be linked together the cultrate suspender of structure of common formation for two among Fig. 1, be hung on the suspension hook by lifting rope (4) again by axle (3).

As can be seen, hang the subtended angle maximum of cutting when hanging to cut to be in when opening unlocked position from Fig. 1, Fig. 4 and Fig. 7, the length of self-locking device (7) is the shortest; When the length of hanging self-locking device (7) when being in latched position (Fig. 2, Fig. 5, Fig. 8) is the longest, stretch in the positioning groove (8), two cut arm retrains mutually; To cut the length that is in lifting control position self-locking device (7) when (Fig. 3, Fig. 6, Fig. 9) shorter when hanging, and is not higher than the inside face of cutting arm (1), and two cut arm is free from each other mutually.

Fig. 4,5, the 6th, the constructional drawing of embodiment.One end of driving lever (6) is positioned at the inside of cutting arm (2), and the other end is the inclined-plane, stretches out and be positioned at the arc groove (9) of cutting arm (1) from the inside face of cutting arm (2), but slide relative.One end of self-locking device (7) is fixed in to be cut in the arm (1), but other end self-locking reduction, its termination are and the cooresponding inclined-plane of driving lever to carry out slide relative with driving lever (6), under the situation of self-locking or release, the movable end of self-locking device (7) is hidden in or stretches out the inside face of cutting arm (1).

Concrete course of action is described below:

1, when cutting arm (1) and (2) when being in position (Fig. 2,5,8), self-locking device (7) is in the unlocked position, its movable end is inserted in the positioning groove (8) of cutting arm (2), has limited the clip of cutting arm (1) and (2) and has dwindled direction and relatively rotate, and has played the blocked effect of cutting of hanging.

2, when cutting arm (1) and (2) gravity and the direction that enlarges to clip under to its antagonistic force of member (5) when relatively rotating the position that is flared to shown in the figure (1,4,7) at self, slide relative is made with the inclined-plane of cutting the last self-locking device (7) of arm (1) in the inclined-plane, outer end that is positioned at the driving lever (6) of cutting arm B (2), and the movable end of self-locking device (7) clamp-oned cut in the arm (1), hang to cut and also be in maximum subtended angle position (Fig. 1), self-locking device (7) is changed to self-locking by release.

3, will hang by lifting rope (4) and cut when slinging, because the gravity of self cuts arm (1) and (2) relatively rotate to the direction that clip dwindles, self-locking device (7) is by self-locking, its head is restricted to be cut in the arm (1), do not retrain cutting arm (2), hang the subtended angle of cutting and diminish and hook member automatically member is sling.As figure (3,6,9)

4, when being winched to, member continues to fall to hanging after the desired location falls to cut, cutting arm (1) and (2) relatively rotates and is flared to figure (1 in self gravity and the direction that enlarges to clip again under to its antagonistic force of member (5), 4, during position 7), slide relative is made once more with the inclined-plane of cutting the last self-locking device (7) of arm (1) in the inclined-plane, outer end that is positioned at the driving lever (6) of cutting arm (2), and the movable end of self-locking device (7) clamp-oned cut in the arm (1), hang to cut and also be in maximum subtended angle position (Fig. 1,4,7), self-locking device (7) is changed to release by self-locking, its movable termination is stretched out and is inserted in the positioning groove (8) of cutting arm (2), two cut arm constraint mutually once more, hang to cut and locked once more, for get ready from hanging up to hang next time.
