Description
Technical field
The present invention relates to technical field of engineering machinery, especially relate to the getting off of bridge formation unit of a kind of anti-hypsokinesis
System and utilize its method carrying out building bridge.
Background technology
Bridge formation unit is mainly made up of the system of getting on the bus and the system of getting off.System of getting on the bus mainly by bridge owner's structure and
Beam-hanging traveling crane forms, and system of getting off is held concurrently by tire type beam conveying vehicle and worked as.Get on the bus and the system of getting off complement one another use,
Its step set a roof beam in place is as follows:
1st step, is shown in that Fig. 1-1, the bridge machine system of getting on the bus become back boom feeding beam state, and rear end walking supporting leg is backward
Tilting, load-bearing rear support leg shrinks, and system of getting off (i.e. tire type beam conveying vehicle) ships beams of concrete from rear
And it being sent into below system back boom of getting on the bus, this process is referred to as " feeding beam ".
2nd step, is shown in Fig. 1-2, and after beam car feeding beam puts in place, system of getting on the bus load-bearing rear support leg falls to prop up and stands on
On the horizontal bearing beam in rear portion of system of getting off, and connect.
3rd step, is shown in that Fig. 1-3, former the portable supporting leg stood on middle bridge pier are advanced to front square pier Zhi Li,
Making Bridge Erector become two straddle mounting beam-like states, beams of concrete is sling from beam car by two overhead traveling cranes.
4th step, is shown in Fig. 1-4, on two beam-hanging traveling crane handling beams of concretes of system of getting on the bus to bridge opening position
Side.
5th step, is shown in Fig. 1-5, and two beam-hanging traveling cranes of system of getting on the bus beam that fallen by beams of concrete is in place.
Said process the 3rd, 4 steps, two supporting legs one of Bridge Erector stand on front square pier, a Zhi Li
On the horizontal bearing beam in the rear portion of the system of getting off.Just from beam car, lift by crane concrete when forward and backward beam-hanging traveling crane simultaneously
Liang Shi, the load capacity on the horizontal bearing beam in beam car rear portion reaches maximum, and beam car front end is as being loaded
Bearing capacity on the horizontal bearing beam of the front fulcrum of beams of concrete is but delivered on bridge main beam by front hanging beam dolly,
Now (former the portable supporting leg stood on middle bridge pier is advanced to the horizontal bearing beam in beam car front end vanishing load
Front square pier Zhi Li).Then, the instant load state of tire type beam conveying vehicle be front light after weight, extremely uneven,
There is the possibility tumbled backward around rear end in vehicle.

Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the present invention is further elaborated.Should be appreciated that this
Specific embodiment described by place, only in order to explain the present invention, does not limit the present invention.
For reaching above-mentioned purpose, the embodiment of the present invention be the technical scheme is that the tire of the system of getting off
Formula is got off car body front end and being tied with special detachable crab-bolt mechanism between frame beams of concrete beam head,
Make to set a roof beam in place after generation is on car body when starting and go all out to be resisted by the deadweight of frame beams of concrete；That is to say will
The car body front end of tire type beam conveying vehicle is anchored on frame beams of concrete beam head, and anchoring mechanism system utilizes dexterously
Set a roof beam in place original hanging beam hole reach detachable anchoring purpose.
Concrete technical measures are to manufacture and design two set detachable crab-bolt mechanisms to be hingedly connected to beam car car body master
Both sides, beam front end, enable the position of detachable crab-bolt mechanism and car body main beam pivot at beam car feeding beam
Para-position is just alignd with original hanging beam hole on frame beams of concrete head after stopping, and then anchor pole is penetrated hanging beam
Hole, anchor nut of screwing on.Crab-bolt mechanism still falls within flexible anchor Chain System, and non-rigid anchor pole generally
Structure, the most only can produce pulling force, will not produce moment of flexure, and mechanical behavior is good.
As shown in Figure 2,3, the present embodiments relate to the system of getting off of the bridge formation unit of a kind of anti-hypsokinesis,
Including: it is arranged on the system of getting off and gets off the detachable crab-bolt mechanism of both sides, car body front end, described crab-bolt mechanism master
Including: anchor chain 1, anchor pole 2, bracket 3, concave surface packing ring 4, convex surface packing ring 5, anchor nut 6, anchor
Shackle 1-2 under shackle 1-1, anchor chain on chain；Wherein, anchor pole 2 upper end is forged into snakehead eye plate, passes through anchor chain
Lower shackle 1-2 is connected with the lower end of anchor chain 1；Anchor pole 2 lower end is threaded, and bracket 3 is packed into anchor pole 2,
It is connected with anchor nut 6 after adding upper recess surface packing ring 4 and convex surface packing ring 5, just constitutes a special dress
Chai Shi crab-bolt mechanism.One piece of otic placode 9-1 with holes is respectively welded in the both sides, vehicle frame main beam 9 front end of the system of getting off,
With shackle 1-1 on anchor chain, anchor chain 1 upper end is connected, then detachable crab-bolt mechanism is just arranged on the system of getting off
The both sides of vehicle frame main beam 9 front end.
The system of getting off of above-mentioned bridge formation unit carries out the method built bridge, and comprises the steps:
Step S101, the bridge machine system of getting on the bus becomes back boom feeding beam state, and rear end walking supporting leg tilts backward, holds
Weight rear support leg shrinks, and system of getting off i.e. tire type beam conveying vehicle ships beams of concrete be sent into get on the bus from rear and is
Below system back boom, this process is referred to as " feeding beam ".
Step S102, when beam car feeding beam para-position, should make beam car is also the system of getting off of bridge formation unit
The both sides, front end of vehicle frame main beam 9 install the position of detachable crab-bolt mechanism just with set a roof beam in place 8 both sides, front
Align in hanging beam hole 7, as shown in Figure 2,3；
Step S103, the anchor pole 2 of detachable crab-bolt mechanism is pierced into set a roof beam in place 8 hanging beam hole, both sides 7, use
Under anchor chain, shackle 1-2 by anchor pole 2 upper end and installs in the both sides, vehicle frame main beam 9 front end of the system of getting off
Anchor chain 1 lower end couples together, then anchor pole 2 lower end pierced in hanging beam hole 7 is packed into bracket 3, concave surface
Packing ring 4, convex surface packing ring 5 and anchor nut 6, i.e. complete whole anchoring operation.So, when getting on the bus it is
When the beam-hanging traveling crane of system lifts by crane beams of concrete from beam car, beam car just can never be occurred to tumble backward
Phenomenon, and ensure that the pitch metacentric stability that beam car that is bridge formation unit are got off.
As can be seen from the above-described embodiment, the present invention utilizes deadweight and the hanging beam hole thereof of frame beams of concrete, logical
Cross crab-bolt mechanism to be anchored at beam car front end and set a roof beam in place on head, thus reached to get off when bridge formation unit is set a roof beam in place
System will not occur to tumble backward, it is ensured that the pitch metacentric stability of system of getting off, have features simple structure, performance safety,
The advantage of cost economy, is that a kind of high-speed railway is accompanied with bridge formation unit general inside and outside frame, tunnel, is state
An inside and outside pioneering new technique.
Obviously, those skilled in the art can carry out various change and modification without deviating from this to the present invention
Bright spirit and scope.So, if the present invention these amendment and modification belong to the claims in the present invention and
Within the scope of its equivalent technologies, then the present invention is also intended to comprise these change and modification.
