Connecting base structure of hydraulic cylinder of material rake of material taking machine

Abstract

The invention discloses a connecting base structure of a hydraulic cylinder of a material rake of a material taking machine. The connecting base structure comprises a girder, a fixing base, a connecting base and the hydraulic cylinder, wherein the middle portion of the hydraulic cylinder is fixedly arranged on the lower portion of the connecting base, the hydraulic cylinder can move in a reciprocating mode along the axial direction of the hydraulic cylinder, the connecting base is fixedly arranged on the fixing base, the fixing base is fixedly arranged on one side of the girder, a protruding portion and a concave portion are arranged on contact surfaces between the connecting base and the fixing base respectively, and the protruding portion and the concave portion are matched with each other. The connecting base structure of the hydraulic cylinder of the material rake of the material taking machine is convenient to manufacture, can be replaced separately during maintenance and can effectively reduce the shearing force of the reciprocating motion of the hydraulic cylinder on connecting bolts of the hydraulic cylinder simultaneously.

Description

technical field [0001] The invention relates to a coupling seat structure of a material rake hydraulic cylinder of a reclaimer. Background technique [0002] Currently used reclaimer, the middle part of its hydraulic cylinder is installed in the lower part of the connecting seat, and the connecting seat is connected with the fixed seat by bolts, and the fixed seat is welded on the side of the main girder. The head of the hydraulic cylinder is assembled with the material rake of the reclaimer, and the reciprocating movement of the material rake is realized through the reciprocating movement of the hydraulic cylinder. During the working process, the connecting seat and the fixed seat are constantly subjected to back-and-forth impacts from the hydraulic cylinder, causing the fastening bolts to be constantly subjected to back-and-forth shearing force. [0003] In the above structural design, the fastening bolts of the fixed seat and the connecting seat need to be reamed hole (t...

AI Technical Summary

Problems solved by technology

During the use of the equipment, once any part of the fixing seat and the connecting seat is damaged, the two parts must be replaced at the same time, which increases the maintenance cost, especially the fixing seat must be cut and removed from the main beam, which is very difficult and greatly affects repair progress

In addition, during production, the bolt holes on the two parts are processed by high-precision machine tools, which greatly increases the production cost.
