Circuit, buzzer sends out alarm；
The foreign steamer of interior driving wheel can drive fixed link rotatable in rotation by the second transmission belt, make the second folded arm to
Upper pressure makes the second folded arm that second hinge arm be pushed to turn right, and the second slide bar is pushed to act upwards, and the second slide bar is made to push lift
It rises arm to rise, lift arm is made to be rotated along drive ball, lift arm can be hit when rotating to the first cam, the second cam simultaneously, make the
One cam, the second cam up rotate, and strike the first promotion ball, the second promotion ball, the first lift lever, the second lift lever are carried
It rises, air bag is elevated, expose composite shell, share the pressure from rubber link block, telescopic mast, make device by slow
Punching, and the alarm acoustic energy sent out is that people have found to handle in time, improves the safety of bridge.
A kind of bridge pedestal telescopic device based on municipal science of bridge building of the present invention, by equipped with overload protection alarm fill
Set, certain cushioning effect can be played when the pedestal of bridge overloads, and send out alarm, enable people to and
When make other safeguard measures, reinforce the safety of entire bridge, enable more to pacify by the vehicle of bridge and crowd
Entirely.

When being docked to bridge pedestal, the pedestal of bridge and rubber link block 1 can be linked together, work as bridge
When being given a shock, pedestal can be also given a shock, and the vibrations of generation can be transmitted downwards from top to bottom to be urged on telescopic mast 2, is made
Telescopic mast 2 moves up and down under the action of driving motor 5, when the shaking force that the pedestal of bridge is subject to is too strong,
2 downward vigorous motion of telescopic mast can be such that telescopic mast 2 is pressed onto by pressure arm 315, allowing and be carried out along gland 316 by pressure arm 315
Rotation, the first folded arm 314 is pulled down, makes pendulum spring 313, first axle arm 312 while moving downward, pendulum spring
313 can reset equipment, when how first axle arm 312 rotates down, can make first by the first slide bar 317 to downslide
Slide bar 317 pushes interior sliding shoe 322, when interior 322 slide downward of sliding shoe, takes advantage of a situation and pushes away cursor 324, linking arm 326 down,
Cursor 324, linking arm 326 is set to move in a circle along center driving wheel 325, center driving wheel 325, which rotates, to be passed through
Transmission belt 337 drives belt pulley 333 to rotate, and the rotation of belt pulley 333 drives the orbit rotation wheel 331 on its surface to rotate, track
Rotating wheel 331 can release drive link 334 when turning to belt pulley 333, so that drive link 334 is released passive pushing block 336, quilt
Dynamic pushing block 336 is slided along sliding rail 335, strikes outer push rod 341, so that outer push rod 341 is pushed and is squeezed inner push-rod 343, inner push-rod
343 squeeze compression reseting spring 344, and lower platen 346 is released, and lower platen 346 is made to be rotated along hinged seat 347, and compression resets
Spring 344 plays the role of reset with hanger spring 345, and lower platen 346 can hit semicircle tooth plate 353 after rotating, and make half
Round tooth plate 353 is rotated around fast pulley 352, and the sawtooth of 353 outer surface of semicircle tooth plate makes external gear 355 rotate, outside
Gear 355 makes the axis wheel 356 on its surface rotate when acting, and axis wheel 356 drives rotor plate 362 by the first transmission belt 361
Rotation, since rotor plate 362 is fixed in outer limitting casing 363 by hinge axis, so rotor plate 362 will not be touched when rotating
To outer limitting casing 363, outer limitting casing 363 can release lift lever 364 when turning to top, and lift lever 364 is made to connect by activity
Bar 365 proceeds by circular motion, and taking advantage of a situation to push on outer driving wheel 366 rotates, and outer driving wheel 366 can drive interior driving wheel in rotation
367 and interior driving wheel 367 foreign steamer, interior driving wheel 367 rotation when, can drive transmission wheel 371 rotation, transmission wheel 371 drive it is small
External gear 373 rotate, small external gear 373 rotation when can by it at the top of upper tooth plate 375 release, upper tooth plate 375 can strike
Piezoelectric patches 376 inside body case of annunciator 377, makes the piezoelectric element on piezoelectric patches 376 be under pressure electric, charge transport is given
Transmission line 379 makes transmission line 379 that the circuit inside buzzer 378, buzzer 378 be activated to send out alarm；
The foreign steamer of interior driving wheel 367 can be driven fixed connecting rod 369 to rotate by the second transmission belt 368, make second in rotation
Folded arm 3611 is pressed upwards, makes the second folded arm 3611 that second hinge arm 3612 be pushed to turn right, and pushes the second slide bar 3613
Action upwards makes the second slide bar 3613 that lift arm 381 be pushed to rise, and so that lift arm 381 is rotated along drive ball 382, lift arm
It can be hit simultaneously to the first cam 383, the second cam 387 when 381 rotation, the first cam 383, the second cam 387 is made up to rotate,
It strikes the first promotion ball 384, second and promotes ball 388, the first lift lever 386, the second lift lever 389 are elevated, by substitute
Capsule 3811 is elevated, and is exposed composite shell 39, is shared the pressure from rubber link block 1, telescopic mast 2, device is made to be buffered,
And the alarm acoustic energy sent out is that people have found to handle in time, improves the safety of bridge.
Problems solved by the invention is that the prior art can directly collapse under pressure when the pressure that bridge pedestal is subject to is too big, is not had
Defence and safeguard measure, make pedestal deform and are not enough to supporting bridge, bridge is easy to happen crack and deformation, influences on bridge
The safety of pedestrian and vehicle, safeguard measure is relatively low, and the present invention is combined with each other by above-mentioned component, occurs in the pedestal of bridge
Certain cushioning effect can be played when load, and sends out alarm, enable people to make other safeguard measures in time,
The safety for reinforcing entire bridge enables more safe by the vehicle of bridge and crowd.
