Meropodium 6 is set up on the bridge pier 8 for waiting to set a roof beam in place at 10, and the front portion of girder 3 is additionally provided with the supporting leg 7 that can be moved along its length, preceding
Guide pillar 4 and BB1 2 specifically can use telescopic oil cylinder, girder 3 and two hanging beam dollies 1 is done lifting fortune
It is dynamic, realized with this and treat rising and falling for the new beam of frame.
With reference to shown in figure 3 to Fig. 5, during via, the frong guide column 4 and BB1 2 of Bridge Erector shrink, and two on girder 3 hang
Beam dolly 1, which is supported on, both set a roof beam in place on bridge floor, and bridge floor is left in the bottom of frong guide column 4 and BB1 2, hanging beam dolly 1 drive girder 3 to
Preceding movement, hanging beam dolly 1 pass through the moveable supporting leg 7 of the front end of girder 3 first during driving girder 3 moves forward
It is supported on bridge pier 8, so that the front end of girder 3 obtains temporary support, until frong guide column 4 and BB1 2 are moved respectively to set a roof beam in place
The top of two bridge piers 8 of opening position, frong guide column 4 and BB1 2 stretch out and are supported on two bridges of opening position of setting a roof beam in place still further below
On pier 8, girder 3 is propped up upwards.
With reference to shown in figure 6 to Fig. 8, when setting a roof beam in place, two hanging beam dollies 1 are moved to the rear end of girder 3, coordinate two one by one
Transport beam dolly 9 and carry out feeding beam, two hanging beam dollies 1 will be after the new beam of frame be hoisted to above position of setting a roof beam in place, frong guide column 4 and BB1
2 shrink, and treat that the new beam of frame together falls with girder 3, on final erection to bridge pier 8.
The mutual cooperation that this erecting machine is only relied between three supporting legs 7 can complete the overall via of equipment, simple to operate, step
It is rapid clear and definite, the equipment via time is greatly reduced, improves via efficiency.In addition, pass through liftable frong guide column 4 and BB1
2, the overall landing of equipment can be achieved, make to change beam process is not influenceed by natural conditions such as wind-force, will not make to fall beam to cause a deviation,
Improve and change beam efficiency；Furthermore it is also possible to effectively reduce the lifting altitude of equipment in work progress, realizing is having track clearance
It is required that operating mode under smoothly complete T-shaped beam change beam operation, it is ensured that do not cause any unnecessary influence on former line facility
Under the premise of, that completes whole hole simple supported T-beam safe efficiently in " skylight point " changes frame construction.
In certain embodiments, the bottom of frong guide column 4 and BB1 2 is equipped with runners, and runners can increase frong guide column 4 with after
The support strength and stability of guide pillar 2, and runners cross-sectional area is preferably greater than the cross-sectional area of frong guide column 4 and BB1 2, so
The lifting surface area of support is bigger, and support is more steady.
The system also includes two rows of tracks and multiple loop wheel machine sleeper beams, multiple loop wheel machine sleeper beams are erected at the T for changing beam position both sides
On type beam bridge, two tracks are respectively erected on multiple loop wheel machine sleeper beams of both sides to be changed of setting a roof beam in place, and two tracks are each fortune beam special train
And the dedicated track of fortune beam dolly 9.
Further, the both ends of multiple loop wheel machine sleeper beams extend the both sides of errant, for supporting frong guide column 4 and BB1
2, the material of loop wheel machine sleeper beam is firm, sets steady, to first upside-down mounting gantry, second upside-down mounting gantry and can change erecting machine and is formed surely
Fixed support.
With reference to shown in figure 3 and Fig. 4, originally changing erecting machine preferably also includes two cushion blocks 5, and two activity mats of cushion block 5 are located at two
The lower section of platform hanging beam dolly 1, i.e., in via, when the frong guide column 4 and BB1 2 of Bridge Erector shrink, two on girder 3 are hung
Beam dolly 1 is supported on by a cushion block 5 both set a roof beam in place on bridge floor respectively, and the pad that on the one hand can so increase girder 3 sets height,
On the other hand, during hanging beam dolly 1 drives girder 3 to move forward, when supporting leg 7 is supported on bridge pier 8, now girder
3 is less positioned at the part at the rear of hanging beam dolly 1, and has reached the rear end of girder 3 by the latter hanging beam dolly 1, this
When the dismountable cushion block 5 by the lower section of the latter hanging beam dolly 1, the hanging beam dolly 1 is moved forward along girder 3, and girder 3 then leads to
Cross the support by previous hanging beam dolly 1 and supporting leg 7 and by being continued to move along by the driving of previous hanging beam dolly 1.
In addition, the lower section of hanging beam dolly 1 is preferably also provided with hoist engine, i.e. hanging beam dolly 1 will be treated by the hoist engine of lower section
10 bindings set a roof beam in place thereunder, and during via, the binding that hanging beam dolly 1 can be by the hoist engine of lower section with both having set a roof beam in place
To increase the stability of hanging beam dolly 1.
With reference to shown in Fig. 1 and Fig. 2, the embodiment of the present invention additionally provides a kind of erecting machine that changes of double-T shaped beam bridge, girder 3
Both lateral sides have the edge of a wing 14；Hanging beam dolly 1 includes moving cart 12 and is provided with and master across beam 13, the top of moving cart 12
The driving wheel that the top side on the edge of a wing 14 of the both sides of beam 3 coordinates, the i.e. top of moving cart 12 have two row's driving wheels, and moving cart 12 is led to
Cross the cooperation of two row's driving wheels and 3 liang of side wing edges 14 of girder and hang and be located on girder 3, the driving wheel is used to drive moving cart 12
Moved along the length direction of girder 3；The bottom side of hanging beam dolly 1 is provided with mounting groove, is arranged in mounting groove and passes through across beam 13
Drive mechanism is provided with hoist engine, the lift rope 11 of hoist engine treats frame for binding relative to the transverse shifting of girder 3 across beam 13
New beam or old beam to be replaced, by the contraction of lift rope 11, the new beam of frame or old beam being bundled under girder 3 tightly will be treated
Side, and then by the transverse shifting across beam 13 relative to girder 3, realize that the bias of T-shaped beam is risen and fallen, so as to realize T-shaped beam bridge
The replacing of upstream side and downlink side roof beam structure.
In summary, it is proposed by the present invention change erecting beam construction technology can ensure not cause existing line it is any unnecessary broken
On the premise of bad, frame construction is changed in the whole hole that freely-supported " T " beam on existing line is safely and fast completed in " skylight point ", effectively
Ground solves the problem of current cost height, workload during changing erecting beam construction, long-term closed-loop, is available for road bureau's permanent-way technology
It is equipped with and uses.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
The present invention is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：It still may be used
To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic；
And these modification or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and
Scope.
