The specific embodiment
Below further specify the utility model by specific embodiment.
As shown in Figure 1, the safe Impact Bucket Grab of a kind of drop point controllable type, it comprises the grab bucket 5 of hydraulic control folding, it is characterized in that: further comprising clamping device 2, framework 1 and lead 3,
Clamping device 2 comprises oil cylinder 22, support 21, chuck 25, two connecting rods 24, two jig arm 23 and spring 26; Support 21 comprises two blocks of side plates and is symmetricly set in the location-plate of two side plate sides that symmetry offers chute on the described location-plate; Two connecting rods 24 all have an end to be connected with the telescopic end bearing pin of oil cylinder 22, and the telescopic end of oil cylinder 22 is positioned at the chute of support 21, and the other end of two connecting rods 24 is connected with the top bearing pin of two jig arm 23 respectively, and 23 bearing pins of two jig arm connect; Spring 26 two ends are fixedly connected with two jig arm 23 respectively, and spring 26 is positioned at the top of the bearing pin tie point of two jig arm 23; The bottom of two jig arm 23 is barb-like, and chuck 25 is fixedly connected on lead 3 tops, and it is barb-like that the top of chuck 25 also is, jig arm 23 and the engaged realization socket connection of chuck 25 by both barbs;
The safe Impact Bucket Grab of described drop point controllable type, be arranged with attitude correcting device 6 around the top of framework 1 outer wall and the bottom, described attitude correcting device 6 comprises top board and drives oil cylinder, the fixed end that drives oil cylinder is arranged on framework 1 outer wall, and top board is connected with the external part bearing pin that drives oil cylinder.
