The specific embodiment

Below in conjunction with accompanying drawing, the utility model is specified:

Arm-tie 4 is made by bar steel plate, and an end is provided with axis hole 2, is provided with limiting stopper 15 in axis hole 2 both sides, and the other end is equipped with bearing pin 5, and bearing pin 5 be cylindrical, crosses arm-tie 4 and is welded on the arm-tie 4, and two ends expose outside.Lock 1 is made up of base plate 3 and side plate 6, side plate 7; Be welded with pipe link 16 between two side plates; To guarantee that the two firmly connects and keeps the distance, side plate 6 is parallel to each other with side plate 7, and all vertical fixing on base plate 3; Distance between the biside plate is a bit larger tham the length of bearing pin 5, thereby can bearing pin 5 be put between the biside plate.In two relative inboards of side plate 6, side plate 7; Be separately installed with riser 110, be separated with cushion block 109 between riser 110 and the side plate 6 (or side plate 7), with spaced apart (narrower as if the lock size; Also can remove cushion block 109 and directly riser 110 is pasted with side plate 6 or side plate 7 mutually); Be manufactured with first glidepath 8, the 3rd glidepath 11, the second rising track 13 on the riser 110, and second glidepath 9, the first rising track 10 be welded on directly on side plate 6 or the side plate 7, first glidepath 8, second glidepath 9, the 3rd glidepath 11 can become 30～60 degree angles with the first rising track 10 and horizontal direction; Present embodiment preferably all becomes miter angle; The orbit plane of first glidepath 8, second glidepath 9, the 3rd glidepath 11 obliquely, this can guarantee bearing pin 5 on orbit plane smoothly to lower slider, the terminal point of first glidepath 8 is the P point; The starting point of second glidepath is the Q point; The Q point is positioned at P point below, and the slit between the two is the exterior slits of the second rising track, 13 orbit planes, and this slit should be able to guarantee to make bearing pin 5 to rise smoothly and slip over.During work, bearing pin 5 is between the outside side plate 6 that gets into lock of lock 1, the side plate 7, gets into or direct entering second glidepath 9 through first glidepath 8 then, continues to drop to the below of the first rising track 10.The orbit plane of the first rising track 10 is oblique down; This can be along guaranteeing that bearing pin 5 rises along orbit plane smoothly; The first rising track 10 links together with arc bearing block 12, and arc bearing block 12 is welded on the side plate 6 (or side plate 7), and situation shown in Figure 4 is that second glidepath 9, the first rising track 10 and arc bearing block 12 are by the one-body molded making of a block plate; And be welded on the side plate 6 (or side plate 7); During work, bearing pin 5 slides to arc bearing block 12 places on the first rising track 10, stops and acting; Then through the 3rd glidepath 11 to lower slider, extruding is hinged on the arc bearing block 12 and overlap joint prevent back sliding centering block 14 and crossing and prevent back sliding the centering block 14 entering second rising track 13 on the 3rd glidepath 11.The second rising track 13 the 3rd glidepath 11 and first glidepath 8 are connected (promptly intersecting at the P point) with first glidepath 11.Below the first rising track 10, be provided with dihedral protruding 17; Protruding 17 1 sides of dihedral are the 3rd glidepath 11; Another side is perpendicular to base plate 3; Its role is to guarantee that bearing pin 5 rises to arc bearing block 12 smoothly through the first rising track 10; Guaranteeing simultaneously can descend to also crossing smoothly when bearing pin 5 is descended by arc bearing block 12 places along the 3rd glidepath prevents back that sliding centering block 14 gets in the second rising track 13, and bearing pin 5 can rise to the P point and further rise to final disengaging lock 1 along the second rising track 13 then.The summit R of dihedral protruding 17 belongs to the diameter that horizontal distance is not more than bearing pin 5 apart from the hinge-point of preventing back sliding centering block 12 18; When this can guarantee that bearing pin 5 rises along the first rising track 10; Can not swing to the below of hinge-point 18 after crossing dihedral protruding 17, thereby can rise to arc bearing block 12 places smoothly.

When producing clamp, welding hanger 103 is hinged on arm-tie 4 on the hanger 103 through bearing pin 108 through axis hole 2 on the hanging beam 102 of caliper 101, and arm-tie 4 promptly can be swung front and back, and limiting stopper 15 can prevent that the arm-tie amplitude of fluctuation is excessive.The base plate 3 of lock 1 is welded on the support plate 105 of caliper 101, and the position is corresponding with arm-tie 4.

The clamp working process is following: when initial; Arm-tie 4 is positioned at lock 1; This moment, bearing pin 5 two ends were stuck in arc bearing block 12 places (f place among Fig. 6), utilized overhead traveling crane to hang hanging beam 102, and hanging beam 102 is passed to lock 1 through arm-tie 4 and bearing pin 5, arc bearing block 12 with pulling force; Through support plate 105 caliper 101 is sling again, caliper 101 is moved to wait to hang on the object then.Then, hanging beam 102 is moved down, then bearing pin 5 prevents back that by f place warp sliding centering block 14 (as shown in Figure 7) moves to the g place, and hanging beam 102 rises then, makes bearing pin 5 move to the b place by the g place through the h place, and then lock 1 is shifted out in rise to a place, and arm-tie 4 is got in touch with lock 1 disengaging like this.Hanging beam 102 continues to rise, and makes pincers tooth 107 move toward one another promptly and promote thing to be hung thereby drive tong arm 106 motions, will thing hung move to the destination after, hanging beam 102 moves down, and thing to be hung is placed on the appointed place.Hanging beam 102 continues to move down then, make arm-tie 4 along a place to the b place route insert in the lock 1 (this process is because the swing of arm-tie, bearing pin 5 maybe through first glidepath 8 also maybe without); Descend along the b-c-d-e place then, rise to the f place along e-f again and stop, this moment, bearing pin 5 was stuck in again on the arc bearing block 12; Return to initial condition, in the process that above-mentioned hanging beam 102 descends, drive tong arm 106 motions pincers tooth 107 is opened; Unclamp thing to be hung, thereby accomplish a working cycle.Follow-up work all repeats this circulation.

Present embodiment is that to the utility model specifies and non-limiting, those skilled in the art utilize common practise or the conversion present embodiment made without creative work still within the protection domain of the utility model.
