Description
Technical field
U-turn construction method is rotated integrally the invention belongs to technical field of bridge construction, on specifically a kind of Bridge Erector bridge.
Background technique
For equilibrium set a roof beam in place progress and consider set a roof beam in place apart from the problems such as, Liang Chang is generally disposed at bid section center, elder generation's frame when setting a roof beam in place
If uplink direction or downlink direction, other direction is set up again after Bridge Erector is driven into the u-turn of beam field opening again later
Box beam.Then at least need to build connection ramp according to the mode that tradition drives into Liang Chang u-turn, cost is huge.
It is provided with cross traveling trolley on general Bridge Erector and 1, No. 2 purlin vehicle, Bridge Erector lower part are mounted on front leg strut, middle vehicle
And in rear car.If can use Bridge Erector itself makes rotation u-turn, working efficiency can be not only improved, engineering can be also saved
Expense.
Summary of the invention
The present invention provides to solve the problems, such as that Bridge Erector turns to and rotates integrally u-turn constructing device on a kind of Bridge Erector bridge
And method.
The present invention takes following technical scheme: u-turn construction method, including following step are rotated integrally on a kind of Bridge Erector bridge
It is rapid:
S100~selection Bridge Erector rotation position, the position of Bridge Erector rotation are adjacent box beam seam crossing;
S200~support top Bridge Erector, beam car back carries Bridge Erector on the back and reaches Bridge Erector rotation position, with vehicle in infrared detection
Stress point and the longitudinal and transverse range deviation of beam face hard point make it be no more than 1cm, integral lifting beam car, until front outrigger for bridge girder erection machine
With rear car and beam identity distance from until reaching 120cm, front leg strut steel pier support pad, rear car sleeper and rail support pad, beam car are carried on the back
1# carries beam on the back and is driven out to Bridge Erector;
S300~rotating device is assembled;
S400~assembly nose girder support frame;
S500~weighing levels Bridge Erector;
S600~connection drive system and preliminary operation;
S700~rotation u-turn;Speed and rotation angle are set, and Bridge Erector slowly revolves under the drive of rotating mechanism
Turn until stopping after 180 degree, by the way that rotation sensor reading data on the spinning device are arranged, determining rotation to 180 degree stops
Only, rotational time is greater than 15 min;
S800~Bridge Erector dropping place.
In the step S300, rotating device includes bracket, bottom bracket and swivel bearing, and bottom bracket is set at four angles
It is equipped with fixation hole, swivel bearing is installed in the middle part of bottom bracket, bracket is installed on the upside of swivel bearing, the setting of bracket two sides is useful
The middle vehicle fixing end of vehicle in fixation, No. 1 purlin vehicle of Bridge Erector hangs bottom bracket in two panels box beam seam crossing, wherein 4 fixations
Hole is overlapped with box beam lifting hole(eyelet), and hanging beam sunpender is respectively penetrated in fixation hole, and 4 screw jack are straight in the jacking of bottom bracket quadrangle respectively
Reach horizontality to subiculum top of support, 80X80cm gravity flowing levelling mortar is perfused respectively around 4 fixation holes, thickness is not less than
5cm is bolted between swivel bearing and bracket again with No. 1 purlin vehicle lifting swivel bearing, bracket and middle vehicle, in
It is bolted between vehicle and bracket, the middle vehicle, bracket and the swivel bearing that unify finally is hung to subiculum with No. 1 purlin vehicle
It on frame, is bolted between swivel bearing and bottom bracket, removes beam car, drop Bridge Erector support, support middle vehicle and nose girder
Frame is interlockingly connected, and nose girder support frame is inverted triangular structure, and nose girder support frame lower part is fixed in bracket, nose girder support frame top
Both ends are fixed with Bridge Erector nose girder, and Bridge Erector is in front leg strut, middle vehicle and rear car supported at three point state at this time.
In the step S400, measure nose girder between bracket at a distance from, front leg strut and rear height are adjusted, with the purlin 1#
Vehicle electric block spelling nose girder support frame is simultaneously bolted fastening with nose girder gusset piece.
The step S500 the following steps are included:
S501, side leveling, Bridge Erector transverse structure are symmetrically, to be laterally substantially at equilibrium state, pass through No. 1 purlin
Cross traveling trolley left and right displacement, that is, levelling on vehicle, No. 2 purlin vehicles, after leveling, cross traveling trolley is fixed.
S502, front truck weighing leveling, Bridge Erector vertical structure be it is asymmetric, need to have been calculated according to distribution of weight level work
The off-position point of No. 1 purlin vehicle, No. 2 purlin vehicles, respectively sets a pressure sensor in two nose girder support frame lower ends, passes through mobile two and rises
Weight purlin truck position is leveled, and when leveling, first uses jack raising front leg strut, then remove a section steel buttress, later again slowly under
Jack is put, hanging 2~5 cm of front leg strut is made, reads sensing data.
S503, rear car weighing leveling, rear car leveling is identical as front truck leveling method, and rear support leg is vacantly not more than when weighing
5cm。
S504, after leveling weighing, No. 1 purlin vehicle of forward and backward movement, No. 2 purlins truck position keep forward and backward nose girder support frame counter-force poor
Within the scope of stationary value, that is, it is less than 500kN;Lateral accurate leveling is moved left and right using cross traveling trolley, and subiculum top of support is made to incline
Angle transducer X axis value is less than 2mm, bundlees No. 1 purlin vehicle, No. 2 purlin vehicles and nose girder after Bridge Erector leveling and fastens, No. 1 purlin vehicle, 2
Locking, cross traveling trolley positioning pin are lockked and are welded before and after the vehicle traveling wheel group rail clamping device of number purlin.
The step S600 clears up the barrier in rotating range, measures live wind speed, and variable-frequency electric is arranged according to wind speed
Machine running frequency, frequency is set as 20Hz when 5.5 ~ 7.0m/s, and frequency is set as 5Hz when 2.5 ~ 3.0m/s, is rotated clockwise 5
Degree, 10 degree, rotate counterclockwise 5 degree, 10 degree.
The step S800, Bridge Erector are rotated in place, and front leg strut and rear car respectively use two bottle gouards moved by hands and beam face pre-buried
Reinforcing bar connection tenses, firm with sleeper and steel pier support pad respectively by front leg strut and rear car raising under jack cooperation, it is ensured that in
Vehicle is separated with nose girder, removes bottom bracket and swivel bearing is connected bolt, rotating device is slid out Bridge Erector respectively with coaster,
Vehicle traveling wheel group and be driven to position of setting a roof beam in place in installation, remove front leg strut and rear car buttress and wind cable, make Bridge Erector nose girder with
Middle vehicle is interlockingly connected, until Bridge Erector is in the state of setting a roof beam in place of supported at three point.
Compared with prior art, the present invention is not required to build ramp, is also not required to dismantling Bridge Erector, rotates u-turn dress using bridge floor
It sets and completes u-turn on bridge.And it has the advantages that
1, structure is simple: used rotating mechanism is divided into three parts, i.e., upper and lower bracket and swivel bearing, and is respectively
Independent monoblock type.
