[CN 201610650190.0] Hydraulic motorized beam jaw locking device


[CN 201610650190.0] Title of a hydraulic motor beam jaw locking device: Application number of a hydraulic motor beam jaw locking device: CN 201610650190.0 Applicant: Hefei University of Technology Application Date: 2016-8-10 Patent Type: Invention Application The present invention discloses a hydraulic motor beam jaw locking device, which includes a stretching mechanism, a locking mechanism and a plate cover. The plate cover is of U-shaped structure, two symmetrical plate cover openings are designed on two sides. The locking mechanism includes an upper jaw, a lower jaw and a spring. The upper jaw includes an upper body and a limit block. The upper body is connected to the plate cover through a pin shaft B. The upper jaw can rotate around the pin shaft B. The lower jaw includes a lower body and a U-shaped opening. The lower body is connected to the plate cover through a pin shaft c. The lower jaw can rotate around the pin shaft c, the stretching mechanism includes a hydraulic cylinder and a cylindrical pin. One end of the hydraulic cylinder is connected to the plate cover through the pin axis a, and the other end of the hydraulic cylinder is connected to the upper jaw of the locking mechanism through the cylindrical pin. The invention has simple structure, small space occupation, light weight and reliable locking effect.
