Description
Technical field
The invention belongs to emergency bridge erection technique fields, and in particular to a kind of emergent bridge nose girder support cylinder buffer system
System.
Background technology
With the development of emergency bridge technology, the erection of emergent bridge and removes and receive stability, safety increasingly by user
Concern, important component of the bridge nose girder support as bridge operation of meeting an urgent need of meeting an urgent need, corresponding functional reliability becomes use
When the factor that need to be considered when, the emergent bridge of easy break-down will have a direct impact on the expansion of rescue work.The pontic of emergent bridge is by bridge
What section and nose girder formed, in erection process, bridge section is motionless, and nose girder reaches barrier distal end from pontic, and pedestal is supported on ground
Face, then bridge section the designated position in front is moved to from nose girder, bridge section will appear the case where being uneven in moving process, lead to
It is often that installation oil cylinder adjusts the lifting of pontic on nose girder, as shown in Fig. 1.In emergent bridge operation process, nose girder support oil
Cylinder is opened and termination phase is time-consuming shorter, and the piston rod of hydraulic cylinder is under hydraulic power driving, in oil cylinder stroke and terminal location
Oil cylinder internal moving parts generate collision, impact and noise with cylinder body, reduce the work of hydraulic cylinder service life and hydraulic system
Efficiency causes pontic to set up the problems such as unstable.Therefore a kind of effectively reliable support cylinder buffer system is needed, with cushion cylinder
The unnecessary mechanical collision brought when work reduces impact damage, and operating mechanism is made to more they tend to smooth motion, ensures bridge of meeting an urgent need
Required movement can be reliablely and stablely completed under various operating modes, it is ensured that emergent bridge operation can be in rescue action orderly
Feasible progress.

In view of this, the present invention provides a kind of emergent bridge nose girder support cylinder buffer system, emergent bridge can be solved and existed
Set up and remove during receiving there is oil cylinder oil leak, oil cylinder praises and acts unstable defect.
A kind of emergent bridge nose girder support cylinder buffer system, the buffer system include oil cylinder, support spring, guide rod, axle sleeve,
Ball cup and pedestal；
The oil cylinder by cylinder body in pontic below plate be fixedly connected, one end of the piston rod of oil cylinder connects with ball cup
It connects, the piston rod other end is connect with oil cylinder internal moving parts, and one end of the guide rod is fixedly connected with ball cup, and the other end is certainly
By passing through plate and top panel below pontic, it is set with axle sleeve and support spring successively on the guide rod, axle sleeve is contacted with lower face,
The upper end of support spring is contacted with pontic upper face, the support spring other end and axle sleeve contact, the ball cup and pedestal activity
Connection, pedestal are supported on road surface.
Further, the ball cup is divided into interconnecting piece and ball head, and the interconnecting piece is used to connect piston rod and guide rod,
The ball head with the spherical nest on pedestal for being flexibly connected.
Advantageous effect：
1. the buffer structure form that the present invention uses is simple, during capable of preferably solving emergent bridge nose girder cylinder efficient
The failure problems of appearance.
2. support spring and axle sleeve tandem compound that the present invention uses can be to the realizations of nose girder support cylinder impact vibration
Cushioning effect.
3. guide rod and ball cup preferably can play guiding role to cylinder movement in the present invention, ensure cylinder piston rod
There is preferable concentricity with cylinder barrel so that cylinder action is reliable and stable.

Specific implementation mode
The present invention will now be described in detail with reference to the accompanying drawings and examples.
As shown in Fig. 2 and 3, the present invention provides a kind of emergent bridge nose girder support cylinder buffer system, the buffer systems
Including oil cylinder 1, support spring 2, guide rod 3, axle sleeve 4, ball cup 5 and pedestal 6；
Oil cylinder 1 by cylinder barrel in pontic below plate be fixedly connected, one end of the piston rod of oil cylinder and 5 activity of ball cup
Connection, the piston rod other end are connect with oil cylinder internal moving parts, and one end of guide rod is fixedly connected with ball cup 5, and the other end is certainly
By passing through plate and top panel below pontic, axle sleeve 4 and support spring 2 are set on guide rod successively, axle sleeve 4 is contacted with lower face,
As shown in Fig. 4, the upper end of support spring 2 is contacted with pontic upper face, 2 other end of support spring and axle sleeve contact, ball cup 5
It is flexibly connected with pedestal 6, pedestal is supported on road surface.
Ball cup 5 divides for interconnecting piece and ball head, and interconnecting piece is for connecting piston rod and guide rod 3, and ball head is used for and bottom
Bulb is limited in the spherical nest of pedestal 6 by the spherical nest flexible connection on seat 6, bulb by snap ring so that cylinder piston rod
There is preferable concentricity with cylinder barrel.
The nose girder support cylinder of the present invention is fixed on one end of pontic end bridge section, during emergent crane span structure is set, bridge
The gradually entirety that collapses is pushed to the level land of opposite bank, and nose girder lands when falling bridge, Auxiliary support pontic.In nose girder support cylinder buffer system
When system work, it is divided into pontic and is lifted and transfers two strokes by oil cylinder.
Under emergent bridge pontic lifting state, steadily frame is placed on level land pedestal 6, and oil cylinder 1 is in emergent bridge integrated hydraulic
Under the driving of system, piston rod therein does stretching movement, and pontic is relative to the styletable 5 in guide rod assembly along the direction of guide rod 3
It is lifted upwards, the axle sleeve 4 being set on guide rod 3 during upper lift is moved together with pontic, due to guide rod assembly (guide rod 3, ball
Shape seat 5) it links together with pedestal 6, it remains stationary, therefore is sleeved on guide rod 3 and the support of rigid contact occurs with axle sleeve 4
Spring 2 can be carried off on pontic and gradually be deformed, and squeeze compression by axle sleeve 4 and pontic, buffering is lifted bridge by cylinder piston rod
Body cause impact, ensure cylinder efficient during it is reliable and stable, oil cylinder 1 drive piston rod by pontic lift is put in specified altitude assignment
Position is reliably completed on emergent bridge pontic and lifts work.
Under emergent bridge pontic decentralization state, similarly, pedestal 6 is smoothly placed on the ground, and oil cylinder 1 is in emergent bridge entirety
Under the response of hydraulic system, the piston rod in oil cylinder 1 does contractile motion, pontic relative to guide rod assembly spheric seat 5 along guide rod 3
Direction moves downward, and the axle sleeve 4 and pontic being cased on guide rod 2 in pontic decentralization process decline together, and support spring 2 is gradually released
It puts, alternating compression amount reduces, and pontic is steadily transferred, until dropping to initial position, completes bridge decentralization action of meeting an urgent need.
In conclusion the above is merely preferred embodiments of the present invention, being not intended to limit the scope of the present invention.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in the present invention's
Within protection domain.
