Abstract

The invention discloses a hydraulic folding and drawing type inner die device which structurally comprises a shell and an inner die device body mounted in an inner cavity of the shell and mechanical connected with the inner wall of the shell. Adjustability of height and width of the inner die device is realized under joint action of a folding device, a height adjusting device and a width adjustingdevice, and size of an inner die can be adjusted according to actual size needs of a die to adapt to production needs.

Description

technical field [0001] The invention is a hydraulic folding and pulling type internal mold device, which belongs to the field of bridge construction equipment. Background technique [0002] At present, most of the prefabrication yards of prefabricated bridges rely on internal formwork auxiliary construction equipment. However, the traditional prefabricated box girder internal formwork adopts the construction method of loose assembly, which is labor-intensive, inconvenient for workers to operate, and takes a long time. The operation is complicated. It needs to consume a lot of manpower and material resources, so that the cost and construction time of the construction are greatly increased, and it is inconvenient to use. [0003] The hydraulic folding and pulling type inner mold device in the prior art cannot be changed in size according to the actual demand to meet the actual production demand. Contents of the invention [0004] In view of the deficiencies in the prior art...
