Abstract

The invention relates to a bridge construction, namely, devices for installation of supports for collapsible bridges, intended for temporary use when blocking shallow watercourses or drywaters. The purpose of the invention is to reduce the time and labor costs in the production of works. The device for mounting the support 1, hingedly attached to the mounted span 2 and horizontally located during transportation along it under it, includes a sling beam 3 installed with the possibility of longitudinal translation along the upper over the mounted span 2 with a trolley. The support 1 is suspended to the sling beam 3 by means of flexible t g 7, and at the level of the lower self-supporting span 2 with additional t g 9, which are placed along the axis of the support 1 and made in the form of guides with a slider moving in them rigidly attached to the mounted span structure 2. Each additional ha 9 has a hinge axis at the end for fastening a special gripper to the support 1 with the possibility of rotation relative to the pull 9 of the support 1 from the horizontal to the vertical position. A winch with bypass blocks and a flexible cable 16 is connected to the sling beam 3, which connects the sling beam 3 to the electric power source of the crane 17, which is used to assemble the span 2 of the bridge. 4 il.

The invention relates to a bridge construction, namely, devices for installing supports for collapsible bridges, intended for temporary use when blocking shallow watercourses or drifts.

The purpose of the invention is to reduce the time and labor costs in the production of works.

FIG. 1 shows a general view of the device with a support in a horizontal position. The device for installation of the support 1 operates as follows.

The crane 17 with the mounted mounted span 2 and laid down longitudinally beneath it in a horizontal position with the support 1 moves the mounted span 2 to the place of its installation. A winch 15 located on the moving sling beam 3 is driven, and the flexible rods 7 are elongated, translated

After installation of the support 1 on the ground in the design position with the help of a rigidly mounted on the mounted span j J DCHL JUJ P ri I V-i / l JLVili- l.rb. j --.-, /

the mounted span 2 is mounted strictly along the axis of support 1.
