Technical Field

[0001] The utility model relates to the technical field of T-beam casting, in particular to a railway T-beam steel bottom plate side mold quick-disassembly pull rod structure. Background Art

[0002] The side mold of the railway T-beam steel bottom plate is a mold used for the railway T-beam steel bottom plate. The T-beam steel bottom plate is an important component on the railway track, used to support the rails and bear the train load. In order to ensure the quality and precision of the T-beam steel bottom plate, a mold is required for manufacturing. After pouring, the mold on the T-beam needs to be removed from the side, and the side mold quick-release pull rod mechanism is required.

[0003] The existing T-beam side formwork quick-release mechanism is not fast and simple enough to fix the side formwork, and the stability is not enough, which easily causes the side formwork to slip when being taken out or fall after being taken out, which is very dangerous. In addition, the quick-release mechanism is not stable enough, and the service life of the hydraulic telescopic rod is short. Therefore, those skilled in the art provide a railway T-beam steel bottom plate side formwork quick-release pull rod structure to solve the problems raised in the above background technology.
