Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0025] This embodiment provides a slide guide mechanism for the bridge span of an emergency mechanized bridge. The guide roller assembly is rotatably connected to the support fixed on the bridge span, and the limit groove I and the limit groove II are set on the support. The switching between the horizontal state and the vertical state of the guide roller assembly is realized, the use of bolts is reduced, the process of pulling out and inserting the bolts is also omitted, and the operation is convenient.

[0026] like figure 1 As shown, a row of guide mechanisms 13 are respectively installed on both sides of the bridge span beam, such as figure 2 As shown, each guide mechanism 13 includes: guide pin shaft 1, guide roller 2, self-lubricating bearing 3, retaining ring 4, positioning pin shaft I5 and support 7;

[0027] The guide pin shaft 1 is a stepped s...

Abstract

The invention discloses a slideway guide mechanism for a bridge span of an emergency mechanized bridge. The slideway guide mechanism comprises a guide roller assembly and supports, the supports are fixed to the two sides of a bridge span cross beam, and the upper surfaces of the supports are provided with limiting grooves I and limiting grooves II in the direction away from the sliding ways. The whole guide roller assembly is cylindrical, one end of the guide roller assembly is provided with a kidney-shaped hole and rotationally connected to the support, a limiting shaft is arranged on the guide roller assembly, and when the guide roller assembly rotates to the position where the axial direction of the guide roller assembly is perpendicular to the plane where the sliding way is located, the limiting shaft falls into the limiting groove I, and vertical locking is achieved; when the guide roller assembly rotates until the axial direction of the guide roller assembly is parallel to the plane where the sliding way is located, the limiting shaft falls into the limiting groove II, and horizontal locking is achieved.

Description

technical field [0001] The invention relates to the technical field of emergency mechanized bridges, in particular to a slide guide mechanism for spans of emergency mechanized bridges. Background technique [0002] The emergency mechanized bridge for emergency rescue and disaster relief can ensure that emergency equipment, construction machinery, small cars, motorcycles and pedestrians pass through obstacles such as small rivers and valleys. During operation, the bridge span slide guide mechanism can make the bridge span be pushed out smoothly according to the direction of the track, and erected to the opposite bank. Bridge span erection operations are more efficient and widely used. [0003] The existing guide mechanism completes the vertical positioning of the guide roller by placing the pin and the wire rope to assist, and then realizes the guiding function; after the guiding operation is completed, the pin is pulled out, and the guide roller is either in a free and unre...
