Abstract
A wind-up method for the main cable used for suspension bridge features that its reel is a combined one, which is composed of a front end cover, a back end cover, and several horizontal arc plates between said front and back end covers and with one front end fixed to said front end cover and one back end hinged to said back end cover. There is a gap between adjacent two arc plates. After said main cable is fully wound, the front end cover is detached and the arc plates are gathered up to become a conic shape, so unloading the wound cable easily.
Description
Technical field
The present invention relates to a kind of method for tightening main cable of new type suspension bridge.Be mainly used in the receipts rope of main rope of suspension bridge strand.Belong to the bridge construction technical field.
Background technology
Traditional suspension bridge main cable rope retracting mode when setting up, is transported to set up scene and expansion with the strand that twists on the steel disk for strand is received on the axis steel disk vertical with the strand direction.Because in transportation and setting up, strand all is wrapped on the steel disk, therefore, its packing cost is higher, and oad is bigger, and for the bridge in some high mountain gorge areas, strand can't be transported to the camp site.
ZL00127808.8 discloses a kind of method for coiling or decoiling bunch of parallel steel wires, and it is on a shaft center line is vertical turntable, to carry out, and the reel of a scalable adjusting diameter is arranged on the turntable; During rolling; The parallel wire unit thigh vertical row coil of wire behind reel, is shunk reel, take parallel wire unit thigh circle away; And with the tread flaking packaged, set up at the scene of being transported to.Mainly there is following deficiency in it:
1, vertically places owing to reel; In receipts rope process from bottom to top; Can't realize the orderly arrangement of strand on the reel, cause main rope of suspension bridge strand fall into disarray, in the main cable strand erection process; Occur phenomenons such as strand intersection, sleave, filoselle easily, influence the quality of main rope of suspension bridge strand.
2, receive in the rope process,, cause the zinc pull-up of strand to fall, have a strong impact on the surface quality of strand because the total weight of strand was pressed on the strand of having packed up afterwards.
Summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of strand of realizing to arrange, guarantee the strand quality in order, and can realize the method for tightening main cable of new type suspension bridge of non-blank package.
The objective of the invention is to realize like this: a kind of method for tightening main cable of new type suspension bridge is characterized in that: the rolling steel disk is arranged to the compound type steel disk, and this compound type steel disk comprises front shroud, back shroud and arc; Said arc has some; Be horizontally placed between front shroud and the back shroud, leave the gap between the adjacent arc, each arc rear end and back shroud are hinged; Front end is captiveed joint with front shroud, forms the flute profile reel.When receiving rope; The main rope of suspension bridge strand is wound on the flute profile reel of horizontal compound type steel disk, behind the receipts hitch bundle, earlier the compound type steel disk is vertically placed; Front shroud is removed; Inwardly draw arc in the formation swift around its lower end again, again strand is deviate from from swift at last, and with the tread flaking packaged.
Compare with existing suspension bridge main cable rope retracting, the present invention has following advantage:
1, receives in the rope process, utilize horizontal reel, realized the orderly arrangement of strand, avoided the zinc pull-up of strand to fall, in main rope of suspension bridge strand erection process, avoided the phenomenons such as intersection, sleave of strand, guaranteed the quality of strand.
2, can dwindle the oad of main rope of suspension bridge strand,, can realize the transportation of strand and set up for the bridge in some high mountain gorges area.
3, realize no steel disk non-blank package, can reduce the packing cost of main rope of suspension bridge strand.

Among the figure: support 1, transmission center shaft 3, compound type steel disk 2, motor 7, miniature gears 6, big gear wheel 4, finger 5, anchor bolt 21, front shroud 22, back shroud 23, arc 24, insulated column 25, latch 26.
The specific embodiment
Referring to Fig. 1, Fig. 1 is a kind of suspension bridge main cable rope retracting device for the present invention adopts, and mainly is made up of support 1, compound type steel disk 2, transmission center shaft 3, canine tooth axle 4, finger 5, miniature gears 6 and motor 7.Said transmission center shaft 3 lateral means are on support 1, and compound type steel disk 2 is placed on the transmission center shaft 3; Said motor 7 mouths link to each other with miniature gears 6, miniature gears 6 and big gear wheel 4 engagements, and big gear wheel 4 is fixedly connected on the transmission center shaft 3, and finger 5 one end devices are in big gear wheel 4 inboards, and the other end inserts in the compound type steel disk 2.
Referring to Fig. 2～3, said compound type steel disk 2 mainly is made up of anchor bolt 21, front shroud 22, back shroud 23, arc 24, insulated column 25 and latch 26.Said arc 24 has some (having 6 among the figure); Be horizontally placed between front shroud 22 and the back shroud 23; Leave the gap between the adjacent arc 24, each arc 24 rear end is hinged with latch 26 and back shroud 23, and front end is captiveed joint with front shroud 22 with anchor bolt 21; Form the flute profile reel, insulated column 25 is vertically packed in the hole of arc 24.
When receiving rope, according to the strand length of required formation, the insulated column 25 of on the flute profile reel of compound type steel disk 2, packing into earlier twists in the main rope of suspension bridge strand on the horizontal flute profile reel, like Fig. 4; After receiving the hitch bundle, earlier compound type steel disk 2 is vertically placed, like Fig. 5; And then with front shroud 22 dismountings, and remove insulated column 25, and inwardly draw arc 24 in the formation swift around its lower end, like Fig. 6, again strand is deviate from from swift at last, and with the tread flaking packaged, like Fig. 7.
