Description

Technical Field

[0001] The invention belongs to the technical field of bridge construction equipment, and in particular relates to a method for turning over an articulated short bridge. Background Art

[0002] A modular bridge is a flexible bridge structure that can be erected as a single unit or by longitudinally splicing two units to form a composite bridge. In this bridge structure, the rut is a key structural component. It is laid within the range of the wheels and tracks and its main function is to carry the load of the vehicle. In the design of modular bridges, the rut can be further divided longitudinally into long ruts and short ruts. When building a modular composite bridge, two sets of long and short ruts are usually arranged in a centrally symmetrical form. The two sets of ruts are connected by a hinge at the bottom, allowing them to rotate around the hinge point. This design allows the rut to adapt to different usage requirements. For example, at the shore end of the bridge, the short rut can be rotated to be flush with the long rut at the bottom; and at the connection between the two bridges, the short rut can be rotated to be flush with the long rut at the top.

[0003] During the erection of the combined bridge, an operation step is required to flip the short rut upward around the hinge point. The current short rut rotation and lifting method is to set a pair of rotatable rods with hooks on the ends on the erection vehicle, and to equip the oil cylinder with the rod in a herringbone shape. The oil cylinder is extended and retracted to drive the rod to rotate and lift. The hook of the rod is hung on the cross tube of the bottom structure of the short rut, thereby supporting the short rut structure to rotate and lift. When the rod rotates downward, the short rut rotates downward at the same time due to its own gravity. This lifting method involves multiple components, including rotatable rods, hooks, cylinders, etc. The assembly and debugging process of these components is relatively complicated, which increases the construction difficulty and time cost.

[0006] Preferably, the upper parts of the long rut and the short rut are connected via an upper joint pin, and the lower parts of the long rut and the short rut are connected via a bridge joint connecting pin.

[0007] Preferably, the vehicle body includes a deck, the guide blocks and pads are arranged on the deck, a vehicle body is arranged below the deck, and a track-driven chassis is arranged below the vehicle body.

[0015] The beneficial effects brought by the present invention are as follows:

[0016] The short rut is flipped by utilizing the translational action of the erection structure on the entire rut. The erection structure mainly relies on pads to support the short rut. The pads have a simple structure and are easy to move and install by manpower, rather than a mechanism fixed on the entire rut to complete the flipping of the short rut, thereby reducing the overall weight of the bridge frame, saving space, and saving production costs. It can be seen from the above scheme that an embodiment of the present invention provides a method for flipping an articulated short bridge. BRIEF DESCRIPTION OF THE DRAWINGS
