Description
Technical field
The utility model relates to anchor head traction dresses after suspension bridge construction technical field more particularly to a kind of suspension bridge dorsal funciculus
It sets.
Background technique
Suspension bridge also known as suspension bridge, refer to main push-towing rope two sides (or bridge both ends) are hung and be anchored in by Sarasota as
The bridge of the main supporting member of superstructure.Its cable geometry is determined by the equilibrium condition of power, normally close to parabola.From
Cable hangs down many sunpenders, and bridge floor is hung, and sets up between bridge floor and sunpender and sets stiff girder, forms combined system with cable,
To reduce deflection deformation caused by load.
The sequence of construction of suspension bridge totality can be divided into following steps: installation saddle, dragline cross river, installation hauling rope, installation
Cat road rope, installation main push-towing rope trailer system, sets up main push-towing rope, installation lock and hoist cable, sets up stiff girder installation cat road.It is setting up at present
When main push-towing rope, main cable erection is generally carried out using PPWS method, i.e., erection construction is drawn using Prefabricated parallel stranded metallic cable.It is general next
Say, every main push-towing rope by it is tens of it is up to a hundred formed with strand, main cable erection, be by strand one by one erection complete.
For there was only the suspension bridge of single span, main cable strand is all made of elongated strand, i.e. the rear anchor head of strand is fixed on
On the anchorage of side, preceding anchor head is drawn and is fixed on by traction mechanism on the anchorage of second side.For multispan suspension bridge, such as twin spans
For suspension bridge or three across suspension bridge, dorsal funciculus can be also arranged other than using elongated strand to carry out to end bay main push-towing rope in main push-towing rope
Reinforce, i.e. the equal length of dorsal funciculus length and end bay main push-towing rope, and be in general divided into two kinds of situations when carrying out dorsal funciculus erection,
The first is that the rear anchor head of dorsal funciculus is fixed on the anchorage of the first side, the preceding anchor head of dorsal funciculus drawn by traction mechanism and be fixed on from
On the nearest saddle of first side anchor heavy stone used as an anchor；It is for second that the preceding anchor head of dorsal funciculus needs to be fixed in the anchoring of second side, rear anchor head needs
It is fixed on the saddle nearest from second side anchorage.In the dorsal funciculus erection process of second situation, the preceding anchor head meeting of dorsal funciculus
First being drawn, current anchor head crosses the saddle nearest from the first side anchor heavy stone used as an anchor, and the rear anchor head of dorsal funciculus will leave the anchorage of the first side,
And anchor head moves together before following, until preceding anchor head moves to the anchorage of second side, rear anchor head is moved to from second side anchorage most
Close saddle, traction mechanism just stop the traction to preceding anchor head.In this process, the rear anchor head of dorsal funciculus will at least cross one
Sarasota and at least through an anchorage door frame, cat road door frame and tower top portal, and current rear anchor head suspension arrangement, are passing through
It will receive obstruction when crossing the guide wheel group of each door frame, dorsal funciculus caused to set up inefficiency.By three across suspension bridge for, in across portion
Point main push-towing rope be a vertex parabola directed downwardly, then dorsal funciculus in process across when, just have one section and be completely in lower ramp shaped
The distance of state, so due to its own gravity of dorsal funciculus, in the distance by this descending, dorsal funciculus is easy uncontrolled
The pendant of the fast ski-running on cat road idler pulley, influence suspension bridge building security.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide anchor heads after a kind of suspension bridge dorsal funciculus to lead
Leading-in device can make anchor head after dorsal funciculus smoothly pass over the guide wheel group of each door frame, and be avoided that dorsal funciculus it is uncontrolled
Fast ski-running pendant on cat road idler pulley.
The purpose of this utility model adopts the following technical scheme that realization:
Anchor head traction device after a kind of suspension bridge dorsal funciculus, comprising: triangle frame body and rope-grippers；The triangle frame body packet
Include the first connector, the second connector and third connector；First connector is set along the direction parallel with hauling rope
Set, and the both ends of first connector are provided with the rope-grippers, the rope-grippers include fixed part and with the fixation
Clamping part portion connection and extended along the circumferential direction of hauling rope；The fixed part is connect with first connector, the folder
The portion of holding is connected on hauling rope to clamp hauling rope.
Further, anchor head traction device further includes balancing pole after the suspension bridge dorsal funciculus, balancing pole one end setting
In the junction of second connector and the third connector, anchor head is connected after dorsal funciculus is provided in the middle part of the balancing pole
The second end of plate, the balancing pole is provided with clump weight.
Further, the clamping part includes the first holding claw and the second holding claw；First holding claw and second armful
Pawl is retractable structure.
Further, the clamping part is provided with guide part, the guide part first along the both ends of hauling rope axial direction
End is fixedly connected with the clamping part, and the guide part second end is tip, and tip is arranged towards hauling rope axial direction.
Further, first connector is channel steel, and the both ends of first connector offer through-hole, described logical
Sleeve is connected in hole, the fixed part secure fit of the rope-grippers is in the sleeve, and the clamping part is from the sleeve
It stretches out.
Further, the first connecting hole is offered in second connecting rod, begins with second in the third connecting rod
Connecting hole, the balancing pole passes through the first connecting hole and the second connecting hole is connect with connecting second connecting rod with third
Bar.
Compared with prior art, the utility model has the beneficial effects that: by anchor head connecting plate after setting dorsal funciculus, dorsal funciculus
Anchor head can be connect with anchor head connecting plate after dorsal funciculus afterwards, so not only the preceding anchor head of dorsal funciculus and the hauling rope of traction mechanism
Connection, and the rear anchor head of dorsal funciculus is also connect with the hauling rope of traction mechanism, then dorsal funciculus in process across when, even if dorsal funciculus is complete
The full state for being in descending, dorsal funciculus can also be drawn well by hauling rope, and it is uncontrolled in cat road idler pulley to avoid dorsal funciculus
Upper fast ski-running pendant, ensure that the building security of suspension bridge, also, such mode compared with the prior art in directly use tower top
Door frame hoist engine is easily more to dorsal funciculus progress reverse drawing, also more cost-effective.And the first connector, the second connector and
Third connector connects into triangle frame body, is because triangle frame body itself just has good stability, this is also ensured that
Reliability when being drawn to anchor head after dorsal funciculus.It is connect with fixed part and in addition, stating rope-grippers and having along the circumferential direction of hauling rope
The clamping part of extension, clamping part are connected on hauling rope to clamp hauling rope, i.e., the utility model is particular by clamping part
Clamping action makes after anchor head traction device draws dorsal funciculus after suspension bridge dorsal funciculus anchor head as the hauling rope of traction mechanism is synchronous
