The invention provides a supporting device for a grab bucket. The bucket section of the grab bucket is arranged on the body of an engineering plant in an opening and closing manner, and the engineering plant is used for installing the grab bucket; the supporting device comprises an oil cylinder, a supporting rod and at least one supporting base, wherein the cylinder barrel of the oil cylinder is rotatably arranged on a body; the supporting rod is rotatably arranged on the body; the first end of the supporting rod is rotatably connected with the piston rod of the oil cylinder; in an expanding and contracting process, the piston rod can drive the supporting rod to rotate; at least one supporting base is arranged on the bucket section; the second end of the supporting rod is matched with the at least one supporting base; and when the bucket section is opened to a preset position, the piston rod supports the bucket section by the supporting rod and the body. According to the invention, structural rigidity of the grab bucket can be reinforced in a more effective manner without occupying the space inside the grab bucket, thus increasing the resistance in the grabbing process of the grab bucket and interfering dumping capacity of the grab bucket can be avoided. The invention further provides the grab bucket and the engineering plant.
Description
technical field [0001] The invention relates to the field of construction machinery, in particular to a support device for a grab bucket, a grab bucket and a construction machinery. Background technique [0002] When the grab is working, the grab needs to have enough impact on the ground, and the impact may be insufficient when digging on a hard bottom surface. [0003] In order to solve the whole problem, patent CN200820155938 discloses an impact grab, which mainly includes left and right big buckets and grab supports, and at least two sets of impact teeth are installed in the left and right buckets, and these impact teeth are fixed on Grab bracket. [0004] The grab of this structure has the following disadvantages: the impact of the bucket teeth on the ground is realized solely by the teeth fixed on the grab support, and the force is small; the bucket teeth are inside the grab, and will Increase the rock entry resistance; when the grab bucket unloads soil, since this st...
