Shield duct piece steel mould end side plate full-automatic open-close device

Abstract

The invention relates to a shield duct piece steel mould end side plate full-automatic open-close device comprising a turnplate, two pairs of joint levers, one pair of side palte joint levers, two side plates, one pair of end plate joint levers, two end plates, a pedestal, end plate and side plate translational lead rails, and the like, wherein the turnplate is connected with the pedestal by a revolute pair and then is respectively connected with the two pairs of joint levers by revolute pairs; the two pairs of joint levers are respectively connected with the two pairs of side plate joint levers and the two pairs of end plate joint levers, which are fixed on the two side plates and the two end plates by revolute pairs; and the four revolute pairs on the turnplate can be on the same circleand not on the same circle. The device has simple structure, easy manufacture and simple and convenient operation, can realize automatic open and close and enhances the efficiency of duct piece manufacture.

Description

technical field [0001] The invention relates to a fully automatic opening and closing device for the end and side plates of a shield segment steel mold, in particular to provide an efficient automatic opening and closing device for the opening and closing of the end plate or side plate of a steel mold for concrete segment steel mold production device. Background technique [0002] The steel mold used to make tunnel concrete segments is mainly composed of base, two side plates, two end plates and their auxiliary parts (embedded device, opening and closing device, locking mechanism, core mandrel, cover plate) Among them, the side plate, end plate, and base (commonly known as: three major pieces) are connected into one body through locking mechanism, and the inner cavity space formed is the actual shape and size of the segment. After the concrete is poured and formed in the cavity space of the steel mold and reaches the specified strength, the side plates and end plates can be...

Problems solved by technology

[0003] Since the angle between the side plate and the base is a right angle, if the hinged opening and closing is adopted, the angle of the hinge will be affected by the angle when the hinge is opened and rotated, which will easily cause the concrete to "gnaw the edge" and damage the segment; and because the volume and weight of the side plate are relatively large, in order to It reduces labor intensity and is easy to operate. Therefore, the opening and closing of the side plate generally adopts the roller translation type. The current general method is to manually pull the side plate to the outside to move a certain distance to complete the opening action. When closing the mold, the side plate is also manually pushed. Move inward to the positioning position

The patent application document [200810022436.5] discloses a translational opening and closing device for the side plate of the tunnel concrete segment steel formwork. The device is manually pushed and pulled to complete the internal and external movement of the side plate. The application document [200820215742.6] discloses an automatic opening and closing device for the side plate translation of the steel formwork of the tunnel concrete segment. Since the screw transmission device is easy to wear when it bears a large load, it is difficult to guarantee the accuracy of the concrete segment, and the opening and closing speed is slow. Therefore, it is necessary to provide efficient, reliable and capable end plates and side plates (hereinafter referred to as: plate) translational automatic opening and closing device
