The specific embodiment
Below in conjunction with accompanying drawing, the present invention is illustrated:
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 is cylindrical, crosses arm-tie 4 and is welded on arm-tie 4, and two ends are outside exposed.Lock 1 is made of base plate 3 and side plate 6, side plate 7, be welded with pipe link 16 between two side plates, both firmly connect and keep the distance with assurance, side plate 6 and side plate 7 are parallel to each other, and all vertically be fixed on base plate 3, distance between biside plate is a bit larger tham the length of bearing pin 5, thereby bearing pin 5 can be put between biside plate.at side plate 6, two inboards that side plate 7 is relative, be separately installed with riser 110, be separated with cushion block 109 between riser 110 and side plate 6 (or side plate 7), with spaced apart (if the lock size is narrower, also can remove cushion block 109 and directly riser 110 and side plate 6 or side plate 7 are affixed), be manufactured with the first glidepath 8 on riser 110, the 3rd glidepath 11, the second rising track 13, and the second glidepath 9, the first rising track 10 directly is welded on side plate 6 or side plate 7, the first glidepath 8, the second glidepath 9, the 3rd glidepath 11 can become 30～60 to spend the angle with the first rising track 10 and horizontal direction, the present embodiment preferably all becomes miter angle, the first glidepath 8, the second glidepath 9, the orbit plane of the 3rd glidepath 11 obliquely, this can guarantee bearing pin 5 smooth down sliding on orbit plane, the terminal point of the first glidepath 8 is the P point, the starting point of the second glidepath is the Q point, the Q point is positioned at below the P point, gap both is the gap of the second rising track 13 orbit plane outsides, this gap should be able to guarantee to make bearing pin 5 to rise smoothly and slip over.During work, bearing pin 5 enters between the side plate 6, side plate 7 of lock from lock 1 outside, then enters or directly enter the second glidepath 9 through the first glidepath 8, continues to drop to the below of the first rising track 10.under the orbit plane of the first rising track 10 is oblique, this can be along guaranteeing that bearing pin 5 rises smoothly along orbit plane, the first rising track 10 links together with arc bearing block 12, arc bearing block 12 is welded on side plate 6 (or side plate 7), situation shown in Figure 4 is the second glidepath 9, the first rising track 10 and arc bearing block 12 are by an one-body molded making of block plate, and be welded on 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, stop and do work, then through the 3rd glidepath 11 down slidings, extruding is hinged on arc bearing block 12 and is overlapped on preventing back sliding piece 14 and crossing and prevent back that sliding piece 14 enters the second rising track 13 on the 3rd glidepath 11.The second rising track 13 the 3rd glidepath 11 and the first glidepath 8 are connected (namely intersecting at the P point with the first glidepath 11).Be provided with dihedral projection 17 below the first rising track 10,17 1 sides of dihedral projection 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 that bearing pin 5 can descend and cross smoothly along the 3rd glidepath when being descended by arc bearing block 12 places back prevent that sliding piece 14 enters in the second rising track 13, and then bearing pin 5 can rise to the P point along the second rising track 13 and also further rise to final disengaging lock 1.The summit R of dihedral projection 17 is apart from preventing back that the hinge-point 18 horizontal distances in place of sliding piece 12 are not more than the diameter of bearing pin 5, when this can guarantee that bearing pin 5 rises along the first rising track 10, the below of hinge-point 18 can be do not swung to after crossing dihedral projection 17, thereby arc bearing block 12 places can be risen to smoothly.
When producing clamp, welding hanger 103, be hinged on arm-tie 4 on hanger 103 by bearing pin 108 through axis hole 2 on the hanging beam 102 of caliper 101, and arm-tie 4 namely can swing 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 as follows: 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 (in Fig. 6 f place), utilize overhead traveling crane to hang hanging beam 102, hanging beam 102 is passed to lock 1 by arm-tie 4 and bearing pin 5, arc bearing block 12 with pulling force, through support plate 105, caliper 101 is sling again, then caliper 101 is moved on object to be hung.Then, hanging beam 102 is moved down, through prevent back that sliding piece 14 (as shown in Figure 7) moves to g place, then hanging beam 102 rises bearing pin 5 by the f place, makes bearing pin 5 move to the b place by the g place through the h place, and then shifts out lock 1 to a place's rise, and arm-tie 4 and lock 1 disengaging contact like this.Hanging beam 102 continues to rise, thereby 106 motions of band movable pliers make pincers tooth 107 move toward one another firmly grasp and promote thing to be hung, will be after hanging thing and moving to the destination, and hanging beam 102 moves down, and thing to be hung is placed on the appointed place.Then hanging beam 102 continues to move down, make arm-tie 4 insert along a place to b place route that in lock 1, (this process is due to the swing of arm-tie, bearing pin 5 may through the first glidepath 8 also may without), then descend along the b-c-d-e place, then rise to f place stop along e-f, this moment, bearing pin 5 was stuck in again on arc bearing block 12, return to initial condition, in the process that above-mentioned hanging beam 102 descends, 106 motions of band movable pliers are opened pincers tooth 107, unclamp thing to be hung, thereby complete a working cycle.Follow-up work all repeats this circulation.
The present embodiment is that one of the present invention is illustrated and non-limiting, those skilled in the art utilize common practise or the conversion the present embodiment made without creative work still within protection scope of the present invention.
