SU1530655A1 - Gantry pier of powered bridge - Google Patents

Abstract

The invention relates to collapsible mechanized bridges and can be used in the construction of mechanized bridges through sukholy watercourses. The aim of the invention is to provide installation of the support at the depths of obstacles of a large range while maintaining the transport dimensions of the support. The gantry support includes an upper girder 1 pivotally connected to four telescopic sliding struts, each of which consists of an upper two-leg part with upwardly diverging part 2, middle @ -shaped two-tube part 3 and lower rod part 4. At the lower ends of part 4 Multilink support plates 5 are fastened. The branches of the upper part 2 of each rack are interconnected between the upper 6 and lower 7 posts. The middle part 3, consisting of two lower connected lower bolt 8 pipes 9, is provided with a locking device for fixing part 3 relative to part 2. The lower part 4 of the column is fixed relative to its middle part 3 by a locking mechanism. Folding the gantry support is carried out by means of a cable block system 31. 6 Il.

Because of the varying length, it is made telescopic, using the square section of the pipe 27 and the corresponding square tip 28 of the shaft extension.

For the drive of the shaft 26 serves as a power cylinder} | dr 29, acting through a new lever 30 mounted on the upper stitch 7 of the upper part 2 of the rack.

The kozlov onor is established as follows.

Paved onto a non-flying structure (not shown) on unlocked unlocked locking devices are laid out in the working position and set on the ground. At the depths of the bottom, the middle part 3 with respect to the top 2 is fixed by the anchor device 13, and the relative separation occurs under the action of the force. The fixing of the lower part 5 occurs by twisting the nut 10 from the action of the power cylinder 29.
