Embodiment Construction
[0024] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0025] Such as Figure 1 to Figure 8 As shown, a self-stabilizing hydraulic grab device includes a mobile frame 1, four self-stabilizing branch chains 2 and a grasping branch chain 3, and the four self-stabilizing branch chains 2 are symmetrically installed on the mobile machine by bolts. The two sides of the frame 1; the grasping branch chain 3 is located between the four self-stabilizing branch chains 2, and the grasping branch chain 3 is welded on the lower end of the mobile frame 1.
[0026] Such as Figure 2 to Figure 4As shown, the mobile frame 1 includes a fixed platform 11,...

The invention relates to a self-stabilizing type hydraulic grab bucket device which comprises a moving rack, four self-stabilizing branched chains and a material grabbing branched chain. The self-stabilizing branched chains are symmetrically installed on the two sides of the moving rack through bolts, and the material grabbing branched chain is welded to the lower end of the moving rack; the moving rack comprises a fixing platform, an installation platform, two T-shaped sliding grooves, two T-shaped sliding rails, a front fixing block, a back fixing block, a first hydraulic telescopic rod, a first lug base, a material grabbing base block and four fixing lugs; each self-stabilizing branched chain comprises an installation block, an upper support rod, a lower support rod, a second lug base, a third lug base, a hydraulic cylinder, a self-stabilizing base block and a connecting spring; the material grabbing branched chain comprises a second hydraulic telescopic rod, an upper fixing sleeve, a lower fixing sleeve, a limit spring and two material grabbing mechanisms. The self-stabilizing type hydraulic grab bucket device can achieve the stable and shakeless material grabbing function, solves the problem that the phenomenon that materials drop or a worker is hurt is caused by existing grab bucket equipment shakes in the material grabbing process, and has the advantages of being good in stabilizing performance, small in material grabbing shake, good in safety performance, high in working efficiency and the like.
Description
technical field [0001] The invention relates to the technical field of grabbing machinery manufacturing, in particular to a self-stabilizing hydraulic grab device. Background technique [0002] The grab is a kind of spreader that mainly depends on the opening and closing of two left and right combined buckets or multiple jaw plates to grab and discharge bulk materials. The grab can be divided into two types: hydraulic grab and mechanical grab according to the driving mode. Large category, the hydraulic grab itself is equipped with an opening and closing structure, generally driven by a hydraulic cylinder, and the hydraulic grab is widely used in hydraulic special equipment, such as hydraulic excavators, hydraulic lifting towers, etc.; and the mechanical grab itself There is no opening and closing structure, and it is usually driven by the external force of a rope or a connecting rod. According to the operating characteristics, it can be divided into a double-rope grab and a ...
