Push-pull type wellhead sealing platform device

The invention provides a push-pull type wellhead sealing platform device. The push-pull type wellhead sealing platform device comprises a plurality of sets of moving devices installed on a wellhead platform. Each set of moving device comprises a supporting base, a guide rail, a channel steel sliding groove and a push-pull type movable closed platform. The supporting base is fixed on the ground; guide rails are mounted on the upper surfaces of the supporting seat and the wellhead platform; the guide rails are in sliding connection with the push-pull type movable closed platform, meanwhile, channel steel sliding grooves are formed in the two sides of the guide rail respectively, and the inner side walls of the channel steel sliding grooves are in sliding fit with the outer side wall of the push-pull type movable closed platform; under the action of an external force, the push-pull type movable sealing platform slides in the rail setting direction of the guide rail and reciprocates between the wellhead platform
