Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 and 2, an intelligent hydraulic floor door driven by a single rod in the present utility model includes a wellhead seat 1, a driving door 2, a driven guard rail 3, a linkage guard rail 4 and a hydraulic cylinder 5. The driving door 2 is hinged with one side of the derrick seat 1 through a hinge, and the driven guardrail 3 is arranged at a position opposite to the driving door and hinged with the other side of the derrick seat through a hinged seat; thereby the driving door 2 and the driven guard rail 3 can both rotate in the derrick base 1 to realize opening or closing actions.

As shown in fig. 2 to 4, between the driving door 2 and the driven fence 3, there is further provided a linkage fence 4, the linkage fence 4 including a driving side fence 41, a driven side fence 42 and a link 43, the driving side fence 41 being vertically fixed at the side of the driving door 2, the driven side fence 42 being vertically fixed at the side of the driven fence 42, one end of the link 43 being connected with the lower portion of the driving side fence 41 through a pin, and the other end being connected with the upper portion of the driven side fence 42 through a pin.
