Multi-degree-of-freedom suspension device for double-hinged oil cylinder of roller press

The utility model discloses a multi-degree-of-freedom suspension device for a double-hinged oil cylinder of a roller press, which is respectively arranged in the middle positions of two sides of the double-hinged oil cylinder and consists of an angular bracket, a suspension rod, a support shaft and a rolling bearing, the angular bracket is fixed on an upper cross beam of a rack of the roller press, and fisheye joint bearings are respectively arranged at two ends of the suspension rod. The fisheye knuckle bearing at the lower end of the suspender is hinged to the double-hinge oil cylinder, the fisheye knuckle bearing at the upper end of the suspender is hinged to the supporting shaft, the rolling bearings are installed at the two ends of the supporting shaft respectively, and the two rolling bearings are arranged on the plane of the angular support, so that the suspender freely swings within a certain range. On the premise that deflection of the oil cylinder is not affected, extrusion force exerted on the oil
