Device.
Background technology
900t Bridge Erectors have Multiple Type, such as SPJ900/32 types, TLJ900 types, integration of transporting and building type, 900t Bridge Erectors
It can set up bridge of the weight in below 900t, and own wt is in more than 500t, because own wt is big, therefore the row under supporting leg
It is double or multiple rows of to sail wheel, is adapted in level land or light grade road surface or bridge floor traveling, and the country uses 900t bridges at present
Circuit is generally typically high-speed railway, and ruling grade is below 25 ‰, therefore, and the Bridge Erector of various models is very suitable for setting up.
But during girder erection by bridging machine, be frequently encountered need reverse end for end situation, and Bridge Erector u-turn need it is flat and
There is the place of enough area, traditional method is, by the lower bridge floor of Bridge Erector traveling, to exist in Liang Chang u-turns, or by means of special rotating disk
Reversed end for end on bridge, Bridge Erector is placed on rotating disk and rotates 180 degree i.e. cocoa and completes to reverse end for end, it is convenient and swift, but by Bridge Erector from bridge floor
The process that platform reaches turret table is then very difficult, because the double or many skate under Bridge Erector supporting leg is not appropriate on ramp
Traveling, directly then has the risk toppled by ramp driving up to turret table face.Usual top rotary table flat surface need to take loss of weight
Measure, or body frame is dismantled, then the assembly on rotating disk table top, by taking SPJ900/32 type Bridge Erectors as an example, then need to prop up before Bridge Erector
Bale handle gantry crane on leg, Bridge Erector nose girder etc. is dismantled, and is mitigated and is travelled up gradient again after weight, but no matter loss of weight or dismounting,
It is cumbersome, big and the shortcomings of waste time and energy using crane, cost in the presence of constructing, therefore, study a kind of overall upper mounting plate of Bridge Erector
Servicing unit is particularly important.

Inverted " L " type hole, snap through inverted " L " type hole and hang on projection.
Further, offset screw rod bottom is fixed by latch with lifting platform.
The operation principle of the present apparatus is：The present apparatus 4 is one group, is respectively placed in and adds in bridge machine under rear support leg tire, by frame
Bridge machine is run on present apparatus lifting platform, one group of device motor of synchronous averaging, and motor tilts spiral shell by gearbox driving lifting
Mother's rotation, the lifting of the rotation nut that inclines drives offset screw rod to rise, so as to drive lifting platform to rise, bridge formation function is integrally hung down
It is straight to rise.
The beneficial effects of the utility model are as follows：
1. the utility model makes the overall vertical ascent of bridge formation, it is not required to dismounting front leg strut and lifts gantry crane loss of weight；
2. can flexibly walk, adapt to Bridge Erector and enter various work condition environments；
3. improve efficiency of construction；
Compared with other traditional ramps, Bridge Erector is lifted by driving into traditional ramp, it is necessary to by bridge formation loss of weight or dismounting
There is cumbersome, the problems such as cost is high, the engineering time is long of constructing, the utility model is safe and reliable, whole in platform over-assemble again afterwards
Body lifting Bridge Erector is not required to loss of weight or dismounting, and the utility model conveniently moving, road wheel of the present utility model is built bridge in lifting
It is pressed into supporting leg, is stretched out under the action of the spring outside supporting leg during walking during machine, is not required to separately operate road wheel.
