Problems solved by technology
The opening and closing process of the bottom mold is the key link in the vertical movement of the mobile formwork. The bottom mold of the mobile formwork in the prior art is generally fixed on the steel beam or hanging beam of the mobile formwork by bolts and screw tops. The installation and mold opening The construction needs enough space, and the mold opening operation is complicated, and the main girder or hanging girder of the formwork needs to be moved as a whole, which cannot be applied to the narrow space under the bridge body and on both sides

The invention provides a bottom die automatic opening-closing system of an upstream moving mould base and a bottom die automatic opening-closing method. The opposite suspended beam automatic opening-closing of the bottom die can be realized without the artificial auxiliary. The bottom die automatic opening-closing system of the upstream moving mould base comprises a bottom die, an automatic pulling mechanism for driving the bottom die to be forward and backward moved along the bottom of a suspended beam, and a bottom die back pressure mechanism and a bottom die hanging wheel component which are coordinated to keep the balance in the opening-closing process of the bottom die. The bottom die and the suspended beam are installed independently. One end of the bottom die handing wheel component is in the sliding fit with the bottom of the bottom die, and the other end of the bottom die handing wheel component is connected with the bottom of a slide rail of the suspended beam. One end of the bottom die back pressure mechanism is connected with the bottom of the bottom die, and the other end of the bottom die back pressure mechanism is in the sliding fit with the slide rail of the suspended beam. One end of the automatic pulling mechanism is connected with the slide rail of the suspended beam, and the other end of the automatic pulling mechanism is connected to the bottom die back pressure mechanism by a driving cylinder.
Description
Technical field [0001] The invention relates to a bottom mold opening and closing system, in particular to an upward moving mold base bottom mold automatic opening and closing system and a bottom mold automatic opening and closing method, belonging to the technical field of bridge building. Background technique [0002] The mobile formwork is a kind of self-contained formwork. It uses the platform or pier column as the support to cast the bridge on-site. It is widely used in the construction of cast-in-place beams of highway bridges and railway bridges. It has short construction period and operation Simple, safe and reliable construction, simple and civilized on site. The opening and closing process of the bottom mold is the key link in the longitudinal movement of the mobile mold base. The bottom mold of the mobile mold base in the prior art is generally fixed to the steel beam or hanging beam of the mobile mold base by bolts and screw tops. The installation and mold opening En...
