The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is further described.
As shown in Figure 1, a kind of Automobile manufacturing suspender, comprise suspension rod and in order to the suspension hook of hook workpiece, suspension rod totally assumes diamond in shape, it comprises and is cross-shaped hinged left suspension rod 11, right suspension rod 12, accordingly, suspension hook comprises left suspension hook 21 and right suspension hook 22, and the lower end of left suspension rod, right suspension rod connects respectively left suspension hook and right suspension hook.Left suspension rod upper end is hinged with the lower end of a left connecting rod 31, similar ground, right suspension rod upper end is hinged with the lower end of a right connecting rod 32, and the upper end of left connecting rod and right connecting rod then is hinged with an oblong hanging block 4, also be provided with lifting hole(eyelet) on this hanging block, in order to be connected with lifting appliance.
Left suspension hook and right suspension hook comprise vertical riser 23, are arranged on the hook section 24 of riser one side lower part and are arranged on two juts 25 that riser the same side upper lateral is arranged.The lower end of left suspension rod, right suspension rod is straight down bending and extension formation gripping section 13 respectively, thereby makes the structure of a similar arched door of bottom formation of left suspension rod, right suspension rod, to hold the workpiece of lifting.The gripping section end of left suspension rod, right suspension rod is fixedly connected with respectively rotation seat 5 to be used for being rotationally connected suspension hook, and rotation seat is the horizontally disposed flange of an axial line; Accordingly, a upper lateral part relative with jut is provided with the turning cylinder 26 of level on the riser of left suspension hook and right suspension hook, this turning cylinder is a stepped shaft, comprise and the auxiliary section 261 of axis hole 51 normal-running fiies of rotation seat and the head 262 of reduced, thereby form a shaft shoulder between head and auxiliary section, left suspension hook and right suspension hook are rotatably connected in the axis hole of rotation seat by turning cylinder.
In addition, be fixedly connected with the friction disc 27 of the flange face of being close to rotation seat near the tail end of riser at turning cylinder, the head of turning cylinder passes the axis hole of rotation seat, two anti-rotation grooves 263 that the head side is provided with outside thread and is arranged symmetrically with vertically, and be connected and fixed nut 64 at head successively sheathed flat shim 61 and anti-rotation pad 62 rear threads, after captive nut was tightened, flat shim was close to the shaft shoulder, deviate from from rotation seat to avoid turning cylinder.In addition, the interior bore edges of anti-rotation pad is provided with two and the adaptive spacing preiection 63 of anti-rotation groove, thereby the anti-rotation pad rotates together in the time of can avoiding turning cylinder to rotate, and guarantees that becoming flexible can not appear in captive nut.Captive nut can adopt hexagon slotted nut, in order to further strengthen its self-locking effect.Certainly the length of auxiliary section should be longer than the length of rotation seat, can guarantee that like this turning cylinder can rotate freely.
Further, be connected with respectively extension spring 9 between left connecting rod and the left suspension rod and between right connecting rod and the right suspension rod, extension spring can drive left and right suspension rod near left and right connecting rod, thereby the left suspension hook and the right suspension hook that are connected to left suspension rod, right suspension rod lower end are opened naturally laterally, be convenient to the hook workpiece and separate with workpiece, thereby make things convenient for the lifting of workpiece.
The excessive clamping of workpiece is caused the damage of surface of the work for fear of left and right suspension hook, can be positioned at prong below the jointed shaft between cross one another left suspension rod, the right suspension rod and arranging the limiting bracket 10 of an A font, one side of this limiting bracket is welded on left suspension rod or the right suspension rod, when the lifting workpiece, left suspension rod, right suspension rod are mutually close, this moment, limiting bracket can limit the size of left suspension rod, the right suspension rod prong opening angle below jointed shaft, made to keep a rational minor increment between the left and right suspension hook.
At last, left suspension rod or right suspension rod have the first handrail 7 at the above partial fixing of jointed shaft, and are fixed with the second handrail 8 at right suspension rod or the left suspension rod gripping section of the following the same side of jointed shaft.The first handrail is roughly L-shaped, its traversing section 71 is used for and is connected the connection of suspension rod or right suspension rod, the handling section that directly can be used as operating personal to section 72 straight down, the end of traversing section is bent to extend to form three square rings 73, one side wherein is welded and fixed with left suspension rod or right suspension rod, in order to make the first handrail have higher Joint strenght.And the second handrail roughly takes the shape of the letter U, and its unsettled two ends are welded on the gripping section up and down, and the intermediate portion then becomes vertical handling section.Certainly, for ease of operation, we also can arrange respectively the first handrail and the second handrail in the both sides of suspension rod, and like this, no matter operating personal all can control suspension bracket easily in which side of workpiece.
The utility model is when the lifting workpiece, lifting appliance is descending, make a left side that is in open configuration, right suspension hook is fallen the both sides of workpiece, it is left that the first handrail can be used for control, the position that right suspension hook falls, then promote the second handrail, make a left side, it is mutually close that right suspension hook overcomes the resistance of extension spring, hook section catches on workpiece, and jut is then pushed down the location with workpiece, and lifting appliance is up, because the effect of workpiece self gravitation, make and be connected to left suspension rod, the left suspension hook of right suspension rod lower end and right suspension hook be inward collapsible naturally, thereby with Workpiece clamping, when the parallel motion workpiece, can utilize first, the second handrail is the workpiece held stationary, avoids occurring swag phenomenon.After workpiece is hung assigned address, being about to workpiece under the lifting appliance is placed into assigned address, at this moment, because workpiece no longer produces application force to left and right suspension rod, therefore under the effect of extension spring, left and right suspension rod is close to left and right connecting rod, and left and right sides suspension hook then naturally outwards opens with workpiece and separates, then lifting appliance is up, can finish the lifting of workpiece.
