Thrust pushes forward blocking box, to stop the impact force of automobile, and is projected backward by rear clump weight, and rear clump weight can be to recoil
One forward reaction force of device makes automobile finally stop and reduces to bridge equally to the impact force for stopping automobile
Damage.
2, multiple countercheck rods are set for stopping automobile, after car hit is on buffer bar, buffer bar are helped to offset first
The impact force of automobile reduces the damage to bridge, and buffering wheel can also help the impact force of buffer bar reduction automobile.
3, after explosive charge, clump weight can be projected by the strength of explosive, and stretch cord can haul clump weight, not allow counterweight
Block arbitrarily collides, and the elastic force of stretch cord can be with the strength of dampened counterweight.
4, shield can protect mounting rod, then protects striker and explosive, makes striker in the external force situation by very little
Under be not easy trigger explosive.

It is connected with buffering tension spring 14；Buffering 14 upper end of tension spring is fixedly connected with buffer bar 15；Upper 15 upper end of buffer bar is fixedly connected with
Stop box 16；Stop 16 rear end face of box to be provided with and stops slot 17；Stop 17 Inner Front End face of slot corresponding with 9 front end of mounting rod；Stop box
16 lower end surfaces rear portion are fixedly connected with tilting bar 18；18 lower end of tilting bar pass through placing groove 3, and with 1 upper end surface rear end of fixed bin
It is fixedly connected；Upper connecting rod 19 is provided in the middle part of upper buffer bar 15；Lower 13 top of buffer bar, lower part be disposed with middle connecting rod 20,
Lower link 21；19 right end of upper connecting rod passes through 15 middle part of upper buffer bar, and be fixedly connected in the middle part of upper buffer bar 15；Middle connecting rod 20 is right
End is fixedly connected across lower 13 top of buffer bar, and with lower 13 top of buffer bar；21 right end of lower link passes through under lower buffer bar 13
Portion, and be fixedly connected with lower 13 lower part of buffer bar；
Between the adjacent upper connecting rod 19 in every left and right, between the middle connecting rod 20 that every left and right is adjacent, the lower link that every left and right is adjacent
It is fixedly connected between 21；Per between neighbouring upper connecting rod 19 and middle connecting rod 20, per neighbouring middle connecting rod 20 and under
Between connecting rod 21, it is fixedly connected to several fixed links 22；Several buffering wheels 23 are mounted in fixed link 22；Counterweight afterwards
6 rear end face lower part of block is fixedly connected to stretch cord 24；24 other end of stretch cord, which is fixed with corresponding 1 rear end face of fixed bin, to be connected
It connects；Recoil 4 front end face of device is fixedly installed with shield 25.
When the present invention uses:
Fixed bin 1 can be fixedly mounted on the step of bridge marginal position to (can be screw fixed form) in automobile
It collides when on upper buffer bar 15 and lower buffer bar 13, firstly, countercheck rod 2, buffering wheel 23 can block automobile, to offset automobile
Impact force.
When automobile cannot stop, the impact force of automobile can be such that buffer bar 15 and lower buffer bar 13 is bent, and arc-shaped
Shape stops automobile to fly out along upper buffer bar 15 and lower buffer bar 13, and buffering pressure spring 12 can withstand lower buffer bar 13, lead to
The elastic force for crossing down the transmitting buffering pressure spring 12 of buffer bar 13, offsets the impact force of automobile, buffers tension spring 14, can also stop lower buffer bar
13 and upper buffer bar 15 be bent, to offset the impact force of automobile.
When automobile still cannot stop, it can impinge upon on tilting bar 18, after automobile overcomes the resistance of tilting bar 18, tilting bar
18 can move backward, and the blocking box 16 of the upper end of tilting bar 18 can also move backward, and the front end of recoil device 4 is made to enter resistance
In retaining groove 17, then, the front end of mounting rod 9 first can be crashed shield 25 with blocking 17 Internal back end face contact of slot, extruding,
With mounting rod 9 is pushed, i.e., striker 10 can be hit makes explosive 26 explode on explosive 26, and front-end weight block 7, rear clump weight 6 is fast
Rapid fire goes out, and front-end weight block 7, which injects, to be stopped in box 16, and is push and stopped box 16 to 16 1 forward power of box are stopped, to support
Disappear the impact force of automobile backward, after then clump weight 6 quickly projects, can give recoil 4 one forward reaction forces of device, same to use
The impact force of automobile backward is offset, after rear clump weight 6 projects backward, stretch cord 24 hauls rear clump weight 6, does not allow rear counterweight
Block 6 arbitrarily projects, and the elastic force of stretch cord 24 can slow down the impact force of rear clump weight 6.
Using the buffer function of multiple buffer units, to slow down the impact force of automobile.
Under normal circumstances, upper buffer bar 15, lower buffer bar 13 height can be higher than the height of automobile, and some oversize vehicles
Center also can be on the lower side, or more buffer bar 15, lower buffer bar 13 can also stop some oversize vehicles.
There are certain frictional force all between mounting groove 5 for front-end weight block 7, rear clump weight 6, can make front-end weight block 7, match afterwards
Pouring weight 6 will not be slided arbitrarily, and be also at certain frictional force between mounting rod 9 and triggering slot 8, and mounting rod 9 will not be slided arbitrarily
It is dynamic.
The explosive 26 of two sides connects together, i.e., after the explosive 26 of triggering side, the explosive 26 of two sides can explode.
26 dose of explosive contacted with rear clump weight 6 is more than 26 dose of explosive that front-end weight block 7 contacts, so explosive 26
After blowing, the strength that explosive 26 is applied to rear clump weight 6 is bigger than the strength for being applied to front-end weight block 6, clump weight 6 after institute
It is bigger to the reaction force of recoil device 4 than front-end weight block 7 to the reaction force of recoil device 4, so after explosive 26 is blown, recoil
Device 4 is whole to will receive forward reaction force, for offsetting the impact force of automobile.
