The installation steps of the erection crane of the utility model are as follows:
Erection crane is lifted on Sarasota area steel box girder bridge face using tower crane discrete item and carries out assembly, and erection crane assembly is complete Bi Hou can carry out unloaded, load and synchronous progress pilot scale study.
Firstly, installation erection crane front fulcrum 100 and rear anchor point 200 are then installed on Sarasota area steel box girder bridge face Stringer 11, lower stringer 12, upright bar 13, preceding brace 14 and rear brace 15, and node structure is installed to consolidate truss structure, and Reinforcing rib 16 is installed in main couple 1 to reinforce the stability of main couple 1, then, installment work platform and lower channel 18, most Afterwards, hoisting system 2, fixed pulley group 4, electrical system 8, hydraulic system 7 and suspender 3 and running block 6 are installed.
After erection crane installs, according to progress loading test is required, the basic mechanical design feature of erection crane is examined, Purpose is to examine the structural-load-carrying capacity of erection crane and its each section, and whether the bridge floor lifting operation that verifying it will carry out may be used It leans on, to ensure the normal operation of erection crane.
No-load test is substantially carried out the following contents: (1), lifting decline, leveling test;(2), walking test;(3) raising is tried It tests.
The mesh of static test is that inspection erection crane and each structural member hold ability, such as has not seen crackle, permanent deformation, paint It peels off or does not also have appearance to loosen wound, stress least favorable point stress the performance of erection crane and the safe damage that has an impact, junction Become in specification is enclosed, then it is assumed that the result of this test is qualified.
The lifting of steel box-girder is carried out after test using erection crane, the specific steps of which are as follows:
Suspender 3 and dress segment, can 360 degree of rotations, realization suspender 3 and beam section lifting lugs using the universal rotational ear specially designed 33 quick connection avoids clamping stagnation, reduces navigation channel holding time.
Unscrew the bolt that main beam 31 is located at 32 both ends of slide, and by mobile bolt, changes the position of bolt with right The moving range of slide 32 plays limitation, then connects beam section lifting lug 33 and suspender 3, slowly tightens lifting rope 22 and each suspension centre is opened Beginning stress, it is whether horizontal with horizontal ruler measurement suspender 3, jack adjustment cunning can be adjusted by the longitudinal slope on suspender 3 if unhorizontal The position of seat 32, it is ensured that the lifting of steel box-girder level, and then guarantee each suspension centre uniform stressed.
When beam section is lifted to bridge floor, this section of steel box-girder is adjusted to having installed using the regulating device 5 on main couple 1 In good edge of steel box girder 30mm, jack 35 then is adjusted using the longitudinal slope on suspender 3 and adjusts deck profile grade, makes it and has pacified The gap width of lower interface is roughly equal on the steel box-girder corresponding position of dress;Horizontal slope is adjusted then by used left and right sides loop wheel machine Difference in height is lifted to control.
Then, it drives steel box-girder to vertically move using the vertical adjustment jack 51 of erection crane front end, makes beam section to Installation beam section is slowly drawn close, while being pulled and being arranged in longitudinal direction and oblique chain block between two beam sections, makes beam section to having installed steel Box beam is drawn close.Before the adjustment of steel box-girder axis and drift angle at left and right sides of box beam using chain block or jack using being carried out Drawing or pushing tow achieve the effect that box beam axis is adjusted afterwards.It finely tunes repeatedly, make steel box-girder and beam section corresponding position has been installed Only top plate alignment at top, bottom plate.
After the section steel box-girder is welded, the steel box-girder for installing next section can be continued, at this point, terminating main couple 1 and bridge floor Anchoring, by running gear 9 erection crane is walked, first by walking oil cylinder 91 push rail contact 93 to push master Truss 1 moves forward a stroke on the walking beam 92, then erection crane is jacked with punching top 94, at this point, bridge floor Loop wheel machine is not affixed with walking beam 92, but since left-hand thread 95 fastens rail contact 93 and walking beam 92, the two is not separated, and is then returned Indention walks oil cylinder 91, and drags the stroke that walking beam 92 is walked forward as the stroke of the movement of main couple 1, and then bounce back punching Rail contact 93 is that main couple 1 is fallen on walking beam 92, repeated the above steps by top 94, until erection crane is walked to specified Position again anchors main couple 1 after the completion of walking.
In addition, loop wheel machine by the cooperation of fixed pulley group 4 and running block 6 with hoisting sling 3, and the number of fixed pulley with The number summation of movable pulley is 14, then making the lifting speed of suspender 3 is the 1/14 of 21 lifting-speed of hoist engine, and steel box-girder 14 times of the pulling force applied with the weight of suspender 3 by hoist engine, to play the role of labour-saving.
The above is only some embodiments of the utility model, it is noted that for the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching also should be regarded as the protection scope of the utility model.
