The working principle of the modularization fast obstacle bridge section:

The modularization bridge section is loaded on erecting device, and there are two bridge section unit 1, stacked on top arrangements altogether；It, can before erection Become ramp and is in unfolded state.When the obstacle that front encounters is smaller, two bridge section units can separate without connection and set up two bridges Beam.

When the obstacle that front encounters is larger, two bridge section units need to be connected, form a longer bridge to overcome Obstacle；The connection procedure of two bridge section units is specific as follows:

1) the bridge section unit being located above moves forward, and underlying bridge section unit is lifted upwards, so that two bridge sections Unit alignment, is placed one after the other, and the variable ramp 2 of two bridge section units is positioned opposite；It is hydraulic in two bridge section units 28 piston rod of cylinder starts to bounce back, and drives swing rod 6 to rotate, while hydraulic cylinder 28 is also started turning itself, and then 6 band of swing rod It moves hydraulic cylinder 1 fixed thereto to rotate around swing rod rotation center, at the same time, one 7 piston rod of hydraulic cylinder first bounces back to be stretched again Out, it drives variable ramp 2 to slide along circular arc slideway 1g, and then realizes the gathering in variable ramp 2, expose female fitting 1e, convex connect Head 1f and connecting hook 5.

2) two bridge section units are close to each other, and pushing-type electromagnet 38 is started to work, and the armature of pushing-type electromagnet 38 is pushed outwardly, Driven rod 2 33 rotates down, and then driven rod 1 moves downward, so that tension spring 35 is stretched, bar 1 drives hanger plate 28 It is rotated down around axis 29, guarantees that hook 3 and hanger plate 28 will not interfere in two bridge section unit approach process in this way；Two bridge sections Unit is close to close to continuing after the contact of two hook bolts 9, and the interactions of two hook bolts 9 is so that hook bolt 9 is rotated around coupler knuckle pin 10, when turning When moving latched position, since the hook bolt closing piece 11d of the effect coupler knuckle lock 11 of gravity is fallen on from the coupler knuckle lock slide surface 9b of hook bolt 9 In lock slots 9c, to prevent hook bolt 9 from turning round, the locking of connecting hook 5 is realized, the convex joint 1f of each bridge section unit is protruded at the same time To inside the female fitting 1e of opposite bridge section unit；Then, pushing-type electromagnet 38 stops working, under the action of tension spring 35, bar two 33 are rotated up, and driven rod 1 moves upwards, and then hanger plate 28 is driven to be rotated up, so that hook 3 catches on hanger plate 28 Spacer pin rotate down hanger plate 28 will not easily and due to the effect of tension spring 35, make hook 3 and hanger plate 28 Connect rigid connection that is more reliable, and then realizing two bridge section units；Wherein, the effect of female fitting 1e and convex joint 1f are subject to bridge The pressure of junction, the effect of connecting hook 5 are subject to the good rear axle section unit bottom of bridge erection at the top of the good rear axle section unit of erection The pulling force of portion junction.Hook 3 is when carrying out bridge erection after the completion of two bridge section units connect, to prevent with the effect of hanger plate 28 Only two bridge section units are detached from.

After bridge withdrawal, the separation process of two bridge section units is specific as follows: pushing-type electromagnet 38 is started to work, hook 3 It is separated with the spacer pin of hanger plate 28；Pull-type electromagnet 25 is started to work, and the armature retraction of pull-type electromagnet 25 drives hook shadoof 23 rotations, move upwards so that lock be pulled to mention 16, and then coupler knuckle lock 11 is pulled to be detached from the lock slots 9c of hook bolt 9, realize connecting hook 5 Unlock, two bridge section units can be smoothly detached；During coupler knuckle lock 11 above mentions, the coupler knuckle lock pusher dog 11c and hook of coupler knuckle lock 11 Tongue pushes away the coupler knuckle lock effect end in contact of iron 12, and after the separation of two bridge section units, coupler knuckle lock pusher dog 11c pushes hook bolt to push away 12 turns of iron Dynamic, the hook bolt effect end that hook bolt pushes away iron 12 pushes the arc acting surface of hook bolt 9, so that hook bolt 9 is flared out with respect to coupler body 13；With Afterwards, pull-type electromagnet 25 stops working, and the armature of pull-type electromagnet 25 stretches out, simultaneously because the effect of gravity, coupler knuckle lock 11 Hook bolt closing piece 11d is fallen on the coupler knuckle lock slide surface 9b of hook bolt 9, and lock mentions 16 lower parts and enters in the coupler body square hole 13b of coupler body 13, even It connects hook 5 and connecting hook unlocking mechanism 40 is returned to initial position, the hanger plate 28 that stops working of pushing-type electromagnet 38 returns to initial bit It sets, is ready for connection next time.
