Fig. 2 is the structural representation that the present invention uses state.
Fig. 3 is clamping device clamped condition schematic diagram of the present invention.
Fig. 4 is that clamping device of the present invention gets loose view.
Detailed description of the invention
The present invention is further illustrated below by way of specific embodiment.
As it is shown in figure 1, a kind of safe Impact Bucket Grab of drop point controllable type, it includes 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 includes oil cylinder 22, support 21, chuck 24, two jig arm 23 of 25, two connecting rods and spring 26；Support 21 includes two blocks of side plates and is symmetricly set in the location-plate of two pieces of side plate sides, and on described location-plate, symmetry offers chute；Two connecting rods 24 all have one 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 fixing with two jig arm 23 respectively to be connected, and spring 26 is positioned at the top of the bearing pin junction 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 top, and the top of chuck 25 is also in barb-like, and jig arm 23 realizes socket connection with chuck 25 by both the engaged of barb；
Framework 1 body interior hollow, being formed around support beam, framework 1 center of inside is provided with at least one pair of directive slide track parallel to each other 4, lead 3 be positioned at framework 1 and with directive slide track 4 interference fits；Lead 3 inner hollow, the end that lead 3 is located in grab bucket 5, it is internal that the hydraulic control unit 51 of grab bucket 5 is located at lead 3；Clamping device 2 is located at framework 1 center of top.
The described safe Impact Bucket Grab of drop point controllable type, the top of framework 1 outer wall and the surrounding of bottom are arranged with attitude rectification device 6, described attitude rectification device 6 includes top board and drives oil cylinder, drives the fixing end of oil cylinder to be arranged on framework 1 outer wall, and top board is connected with the external part bearing pin driving oil cylinder.
The described safe Impact Bucket Grab of drop point controllable type, the end of directive slide track 4 is provided with stopping means.
The described safe Impact Bucket Grab of drop point controllable type, the end of directive slide track 4 is provided with buffer gear.
The described safe Impact Bucket Grab of drop point controllable type, the top of lead 3, the inwall of framework 1 are provided with the position sensor that coupling uses.
The present invention uses above-mentioned design, directive slide track 4 to coordinate the use of lead 3 so that the falling direction of Impact Bucket Grab becomes it can be appreciated that simultaneously, special clamping device has dual holding function, it is ensured that the clamping reliability of Impact Bucket Grab.
Specifically, as shown in Figure 1 and Figure 2, it is directed to during use that post 3 and chuck 25 is fixing to be connected, then makes the jig arm 23 of the held mechanism of chuck 25 2 clamp, thus reach the purpose of fixed guide post 3, owing to there is spring 26 and the double reaction plus of oil cylinder 22, therefore, actual had two active forces to be directed to post 3 to fix to clamp fixing, so within the same time, play the effect of dual fail-safe, thus improve the safety in utilization of Impact Bucket Grab；As shown in Figure 3, Figure 4, during action, the oil cylinder 22 of clamping device 2 receives action command and shrinks, effect lower spring 26 at connecting rod 24 compresses, jig arm 23 is opened, and chuck 25 departs from, and lead 3 leads fallen downward directive slide track 4, the Impact Bucket Grab 5 making lead 3 end finally falls on predetermined impact point, thus also improves the accuracy of Impact Bucket Grab；Meanwhile, framework 1 outer wall is provided with attitude rectification device 6, when finding that hole off-design requires, can carry out the attitude of coordinating frame by the dilatability between regulation different driving oil cylinder and reach perpendicular to the ground or other design requirement.In sum, instant invention overcomes the whereabouts existing for the grab bucket of existing conventional impact uncontrollable, the use of the low grade of entrapment, design defect.
