Automatic bolt mechanism of telescopic movable bridge

Abstract

The invention relates to an automatic bolt mechanism of a telescopic movable bridge. The automatic bolt mechanism comprises a power assembly, a support assembly and a connecting assembly, wherein thepower assembly is connected with the support assembly through the connecting assembly; a pin shaft assembly is assembled in the connecting assembly; the support assembly is fixedly arranged on a fixedbridge frame of the movable bridge through bolts; a bolt assembly is arranged in the support assembly; the power assembly is used for outputting driving force; the pin shaft assembly is used for transmitting driving force; and the bolt assembly is used for receiving driving force to achieve translational telescopic motion. Compared with the prior art, based on the safety of the opening and closing processes of the movable bridge, the driving force is provided by a motor, and a bolt is driven by the transmission of a gear and a rack to perform translational telescopic motion between collisionpoint grooves; and the automatic bolt mechanism has the advantages of being simple to operate, reliable in transmission and capable of effectively assisting in locking a bridge frame.

Description

technical field [0001] The invention relates to the technical field of a telescopic opening bridge, in particular to an automatic latch mechanism of a telescopic opening bridge. Background technique [0002] Compared with the bridge whose main girder cannot move, the open bridge can shorten the length of the approach bridge, reduce the amount of embankment engineering, and reduce the height of the pier. You need to build a bridge. The telescopic opening bridge is a new type of opening bridge designed for the purpose of increasing the safety of opening, reducing the scale of opening machinery and creating a new opening appearance. Compared with the traditional opening bridge, the telescopic opening bridge is to make the bridge span structure and The bridge deck is displaced along the longitudinal axis of the bridge, that is, the opening of the bridge is realized by means of translation and expansion. [0003] At present, a bolt mechanism is usually installed between the fix...

AI Technical Summary

Problems solved by technology

[0003] At present, a bolt mechanism is usually installed between the fixed bridge frame and the movable bridge frame of the telescopic open bridge. The opening and closing of the bridge needs to be completed by the bolting and pulling operations of the bolt mechanism. The actual operation needs to be done manually, and there are certain operations In addition, the existing latch mechanism cannot effectively lock the movable bridge frame, making the open bridge vulnerable to external force or misoperation and misoperation, which is likely to cause safety accidents
