Fixing structure of two-leg shield type hydraulic support four bar mechanism

The utility model discloses a fixing structure of a two-leg shield type hydraulic support four bar mechanism. A front connecting rod and a rear connecting rod are arranged on the two sides of the hydraulic support respectively, the upper ends and the lower ends of the front connecting rod and the rear connecting rod are hinged to a caving shield and a base respectively, the front connecting rod arranged on one side of the hydraulic support is detached, and the hinge point of the upper end of the rear connecting rod on the side and the caving shield is detached and then installed in the position of the hinge point of the upper end of the original front connecting rod and the caving shield. The fixing structure of the two-leg shield type hydraulic support four bar mechanism has the advantages that the fixing structure can be applied to the fixing of the four bar mechanism used in the balance mechanism extrinsic load tests of all two-leg shield type hydraulic supports, the use is flexible, the operation is convenient, and an external tool is not needed to be added.
