Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

As shown in fig. 1-3, a flashboard test device comprises a base 1, wherein a support 7 is arranged on the base 1, the lower end of the support 7 is fixedly connected with the base 1, the upper end of the support 7 is connected with a cross beam 8 through a bolt, a plurality of hydraulic cylinders 9 are arranged on the lower portion of the cross beam 8, the number of the hydraulic cylinders 9 can be 4, and the 4 hydraulic cylinders 9 work simultaneously. A piston rod of the hydraulic cylinder 9 is fixedly provided with a balance pressing block 10.

The upper end of the base 1 is provided with a triangular guide rail 4, the triangular guide rail 4 is provided with a movable platform 2 in a sliding mode through a roller 5, the movable platform 2 is provided with a damping spring 3 and is elastically connected with a working platform 6, a blocking disc 11 is arranged on the working platform 6, the opening end of the blocking disc 11 is provided with a sealing ring 12, a flashboard is installed on the blocking disc 11, the blocking disc 11 and the flashboard are assembled to form a sealing cavity, and the flashboard is tightly attached to the sealing ring 12 to guarantee good sealing.
