Problems solved by technology

There is a grab consisting of a bucket body and two ear plates connecting the two sides of the bucket body. The ear plate is provided with a connecting hole inlaid with a bushing. The grab is installed on the lifting machine through the ear plate. Under the gravity of the material, the lugs of the grab bucket are prone to deformation, the distance between the two lugs becomes larger, and the vertical surface of the lugs is twisted
At present, chain hoists are usually used to hook the connecting holes of the e

Example Embodiment

[0012] The present invention will be described in further detail below with reference to the embodiments of the drawings:

[0013] Such as figure 1 , figure 2 The illustrated tool for adjusting the deformation of the grab ear plate includes three screws 3 arranged at intervals. The two ends of the screw 3 are sleeved with two oppositely arranged pressure plates 1, and the screw 3 is located at the outer ends of the two oppositely arranged pressure plates 1 Nuts 2 are installed everywhere, and the middle of the pressing plate 1 is provided with a flange perpendicular to the screw 3.

[0014] When working, put the two ear plates of the grab on the middle screw 3 between the two oppositely arranged pressure plates 1 at each end. If the distance between the two ear plates becomes larger, adjust the middle screw 3 At the end of the nut 2, move the two pressing plates 1 located at the two ends of the screw 3 to the middle to compress the ear plates, adjust the two ear plates to the set di

Abstract

The invention discloses a grab bucket ear plate deformation adjusting tool and relates to the technical field of hoisting machinery maintenance. The tool comprises at least three screws arranged at intervals, wherein the same end of the screws is sleeved with two oppositely arranged press plates, nuts are arranged on the screws and located outside the oppositely arranged press plates, and a flange perpendicular to the screws is arranged in the middle of each press plate. Compared with the prior art, the grab bucket ear plate deformation adjusting tool has the advantages that two ear plates of a grab bucket are installed on the parts, between every two oppositely arranged press plates at the two ends, of a middle screw in a sleeved mode, the ear plates are pressed by the press plates by adjusting nuts of the middle screw to enable a set distance to be formed between the two ear plates, adjusting precision is high, and operation is safe; the two ear plates are fastened by every two oppositely arranged press plates located at the two ends of the screws by adjusting the nuts of the middle screw, the press plates are pushed to clamp the ear plates by adjusting nuts located on the screws on the two sides, and then the vertical planes of the ear plates are corrected to meet technical requirements.
