Description
Technical field
This utility model is related to main cable saddle of suspension bridge, specifically a kind of main cable saddle pushing tow position limiting structure.
Background technology
In suspension bridge construction project, the especially construction of large-scale suspension bridge construction project, in order to ensure king-tower can be steady
Gravity fixed, that reliably carrying main push-towing rope is transmitted, needs are carried out the main cable saddle arranged at the top of king-tower necessarily in During Initial Stage Construction
Pre- deviator process, will the pre- deviator that set toward end bay side on its base of main cable saddle saddle body process；With construction
Progress, by making pre- deviator of the saddle body on base by successive elimination across the progressively pushing tow of side in saddle body, until being built
Into suspension bridge engineering main cable saddle can meet design requirement stand on king-tower top, and then guarantee that king-tower can be located all the time
In the stress of design requirement, while also ensuring that the stress of main push-towing rope is in poised state.
It is not in place etc. in interior complicated factor based on weather conditions, construction organization however, in the construction of suspension bridge
Impact, may there is the potential safety hazard that in across side displacement increases suddenly, or even meeting during pushing tow in the saddle body of main cable saddle
Make saddle body off-design position and in impinging upon on the baffle plate of side, cause the serious consequence that cannot be estimated.In view of this, outstanding
It is shown in Figure 1 in the structure design of cable bridge main cable saddle, it usually needs design pushing tow position limiting structure, traditional main cable saddle pushing tow limit
Bit architecture includes saddle body 1 and the base 2 for matching, and is respectively welded in the bottom of the both sides of saddle body 1 and is provided with the spacing company in a saddle side
Block 11 is connect, is also respectively welded in the both sides of bottom deck 22 of base 2 and is provided with the spacing contiguous block 21 of a base side, the every side of main cable saddle

Mother is locked on the spacing contiguous block 11 in saddle side and the spacing contiguous block 21 of base side, and the nut on limit pull rod 3 is with pushing tow position
The progress of shifting and controllable progressively unscrew high-volume, it is ensured that pushing tow of the saddle body on base can be controllable, stable, reliably and securely
Carry out.
In contrast traditional main cable saddle pushing tow position limiting structure can take king-tower top originally narrow space, be unfavorable for construction
Operation, so as to occur in that the pushing tow position limiting structure on the basis of main cable saddle end bay side end, such as Chinese patent in prior art
" main cable saddle pushing reaction device " disclosed in document（Publication number：CN 204780603, publication date：On November 18th, 2015）.Should
Although technology can realize the pushing tow position limiting structure on the basis of main cable saddle end bay side end, it needs the base in main cable saddle
Upper individually to increase the big pushing reaction device of design complexity, manufacture difficulty, it is present, and profiled part is more, manufacturing cost is high, molding
The problems such as difficulty is big, practicality and reliability it is poor.
The content of the invention
Goal of the invention of the present utility model is：For above-mentioned the deficiencies in the prior art, make main cable saddle pushing tow is not affected
On the premise of industry, there is provided a kind of simple structure, save king-tower top construction space, reduce profiled part, lower molding difficulty and
The main cable saddle pushing tow position limiting structure of cost.
The technical scheme that this utility model is adopted is：A kind of main cable saddle pushing tow position limiting structure, including saddle body and base, institute
The top surface for stating base is provided with the reaction frame of at least one pushing tow, and the saddle body is provided with and reaction frame phase towards the end of reaction frame
The spacing contiguous block in corresponding saddle side, the reaction frame is used as the spacing contiguous block of base side on base, corresponding saddle side
At least one limit pull rod is provided between spacing contiguous block and the spacing contiguous block of base side.
Preferably, the reaction frame of the base top surface is two of interval and separate arrangement, and the two are anti-
Power frame is respectively as the spacing contiguous block of base side on base.Further, the reaction frame on the base is gridiron.
Preferably, the front portion of the reaction frame is provided with jack stand, and the jack stand is in spacing drawing
The lower section of bar.Further, the jack stand is gridiron.
The limit pull rod is locked respectively by nut on the spacing contiguous block in saddle side and the spacing contiguous block of base side.
Preferably, the spacing contiguous block in the saddle side is the end floor itself on saddle body.
The beneficial effects of the utility model are：Above-mentioned pushing tow position limiting structure is with itself existing counter-force on main cable saddle base
On the basis of frame, carried out with pushing tow displacement of the main cable saddle end bay side end to saddle body on base effectively and reliably spacing, it is not only
The pushing tow operation of main cable saddle is not interfered with, and its design structure is simple, can effectively save the construction space at the top of king-tower,
While the profiled part of position limiting structure can be efficiently reduced, and then the molding difficulty and manufacturing cost of main cable saddle are reduced, reliable,
It is practical.
