Problems solved by technology

[0002] The existing mechanized bridge erection mechanism can realize the mechanized erection of the bridge span, but it does not have the function of driving the bridge span to expand laterally. When the bridge span width needs to be adjusted, it is often adjusted through a manual adjustment device installed on the bridge span, or Setting the widening part on the bridge span can solve the problem of span width adjustment, but it has the disadvantages of low operating efficiency and difficult adjustment

Embodiment 1

[0036] Embodiment 1: see attached Figures 1 to 13 , an erecting mechanism for a width-adjustable mechanized bridge, comprising: a chassis vehicle, a sub-frame 1, a front transverse bridge spreading mechanism 2, a stabilizing outrigger assembly 3, an erecting frame assembly 4, a rear transverse spreading bridge mechanism 5, folding Pull rod 6, tongue arm assembly 7, hydraulic system and electrical control system;

[0037] The sub-frame 1 is a side-beam frame structure, which is directly fixed on the girder of the chassis vehicle. The upper part of the front end of the sub-frame 1 is provided with an outer arm 8 of the front transverse bridge extension mechanism along the transverse direction;

[0038] The front transverse bridge expansion mechanism 2 includes: the front transverse bridge expansion telescopic arm 9 and the telescopic oil cylinder 10; the two front transverse bridge expansion telescopic arms 9 are symmetrically installed in the outer arm 8 of the front transvers...

Embodiment 2

[0045] Embodiment 2: see attached Figures 14 to 21 , a method for erecting a width-adjustable mechanized bridge, which uses the erection mechanism of a width-adjustable mechanized bridge as described in Embodiment 1, comprising the following steps:

[0046] Step 1: Lock the bridge span on the tongue arm assembly 7, transport the erection mechanism and bridge span of the width-adjustable mechanized bridge to the predetermined erection position through the chassis vehicle, and complete the bridge erection preparation;

[0047] Step 2: The left outrigger 14 and right outrigger 12 of the stabilizing outrigger assembly 3 swing into place and reliably support the ground, loosen the locking bridge mechanism on the tongue-shaped arm assembly 7, and then operate the front transverse bridge spreading mechanism 2 and the rear The horizontal bridge extension mechanism 5 acts synchronously with the horizontal stabilizer on the bridge span, adjusts the width of the bridge span to the requi...

Abstract

The invention belongs to the technical field of mechanized bridges, in particular to a width-adjustable erecting mechanism and method for a mechanized bridge. The technical scheme of the width-adjustable erecting mechanism for the mechanical bridge is characterized in that the width-adjustable erecting mechanism comprises a chassis car, an auxiliary car frame (1), a front horizontal bridge-expanding mechanism (2), a support leg stabilizing assembly (3), an erection rack assembly (4), a back horizontal bridge-expanding mechanism (5), a folding pull rod (6) and a tongue-shaped arm assembly (7),a hydraulic system and an electric control system. During operation, the hydraulic system is adopted to drive the front horizontal bridge-expanding mechanism to automatically finish adjusting the width of a bridge span according to the type of travelling equipment as needed. Therefore, travelling requirements for different types of equipment can be met without needing a manual-operated width adjusting device and a widening part of the mechanical bridge. The trafficability, maneuverability, working efficiency and adaptability are all improved. The width-adjustable erecting mechanism and methodfor the mechanized bridge are adapted for multiple operation scenarios including natural disaster rescue such as anti-seismic and flood-fighting efforts and defense efforts of troops.

Description

technical field [0001] The invention belongs to the technical field of mechanized bridges, in particular to a mechanism and method for erecting mechanized bridges. Background technique [0002] The existing mechanized bridge erection mechanism can realize the mechanized erection of the bridge span, but it does not have the function of driving the bridge span to expand laterally. When the bridge span width needs to be adjusted, it is often adjusted through a manual adjustment device installed on the bridge span, or Setting the widening part on the bridge span for adjustment can solve the problem of bridge span width adjustment, but it has the disadvantages of low operating efficiency and difficult adjustment. Contents of the invention [0003] The object of the present invention is to provide an erection mechanism for a width-adjustable mechanized bridge, which can drive the bridge span to expand and retract horizontally as required during the mechanized erection operation,...
