Description
Technical field
The utility model relates to be used for science of bridge building prestress wire lashing auxiliary device field, specially a kind of steel is twisted
Line auxiliary traction head.
Background technique
In science of bridge building, in order to avoid twisted wire caused by single lashing is mutually wound in steel stranded wire penetrating adapter construction, cause
Twisted wire stress is seriously uneven when tensioning, is both needed to carry out lashing using whole beam lashing mode, steel stranded wire penetrating adapter is all made of in steel at present
Twisted wire end setting drawing head is carried out by way of wire rope traction.Wherein the setting direct relation steel of steel strand wires traction end twists
The smooth degree of line lashing, it is conventional using modes such as steel strand wires welding bunchy, steel strand wires snap ring bunchys, but fiber crops are operated with upper type
It is tired, it constructs more difficult, and quality is difficult to ensure.
There is presently no the tractions that the drawing head of a effective simplicity can efficiently be used for steel strand wires end, cause construction not
Just.
Summary of the invention
In order to solve the problems, such as that the processing of current steel stranded wire penetrating adapter traction end end is more difficult, the utility model aim is to provide one
Kind steel strand wires auxiliary traction head, facilitates steel stranded wire penetrating adapter to construct, and improves construction efficiency.
The utility model adopts the following technical scheme that realization:
A kind of steel strand wires auxiliary traction head, including cone sleeve and traction screw；The traction screw passes through cone sleeve,
Described traction screw one end is installed with traction end, and the cone segments that cone sleeve is located on the traction screw are screwed with movable screw
It is female, be equipped with fixture nut and disc core positioned at the socket end of cone sleeve, the disc core surrounding is axially arranged with steel wire trough.
Using principle, steel strand wires take the steel wire trough that disc core is caught in after process wire pier nose, are driven by twisting traveling nut
Disc core enters inside cone segments, and steel strand wires are fixed with anchor.Traction rope is fixed on traction end head and drives entire drawing head device and then band
Dynamic steel strand wires.
When work, combing is arranged it after steel wire, is cut each bitter end head of the end steel strand wires with abrasive cutoff saw
20~30cm, but retain that root diameter of phi 5mm steel wire of center, central hair is penetrated into button head machine, heading diameter is greater than in drawing head
The diameter in core plug hole (steel wire trough in disc core), to meet the requirement that steel wire trough can block main steel strand wires.
Each slot is away from slightly larger than with steel wire diameter, the steel strand wires after heading are caught in the steel wire of disc core among steel strand wires in disc core
In slot, the traveling nut on screw rod is twisted by spanner, drives disc core to enter cone sleeve inner, steel strand wires is drawn by disc core
Central hair is caught in inside cone segments, and steel strand wires are locked.
Breechblock draws end and connects traction by the wirerope on hoist engine.Steel strand wires end before steel stranded wire penetrating adapter (including cut
Cut part) it must be wound and be protected with adhesive tape, prevent steel strand wires end during lashing from dissipating rope.It is slowly drawn when lashing by hoist engine whole
Whole beam lashing is completed in the translation of bundle strand line.
The utility model is ingenious in design rationally, easy to operate, can be widely applied in the bridge prestress work such as highway, railway
Journey construction, has good practical application and promotional value.

Specific embodiment
Specific embodiment of the utility model is described in detail with reference to the accompanying drawing.
A kind of steel strand wires auxiliary traction head, as shown in Figure 1, 2, 3, including cone sleeve 1 and traction screw 2；Traction screw 2
Across cone sleeve 1,2 one end of traction screw is installed with traction end 3, and the cone segments that cone sleeve 1 is located on traction screw 1 are revolved
There is traveling nut 4, be equipped with fixture nut 5 and disc core 6 positioned at the socket end of cone sleeve 1,6 surrounding of disc core is axially arranged with steel wire trough
7。
As shown in figure 4, arrange it combing after 8 blanking of steel strand wires, with abrasive cutoff saw by each bitter end head of the end steel strand wires
20~30cm is cut, but retains 5 steel wire of that root of center Φ, central hair is penetrated into button head machine, 9 diameter of heading is greater than drawing head inner core
The diameter of consent (steel wire trough in disc core), to meet the requirement that steel wire trough can block main steel strand wires.
As shown in Figure 5,6, in disc core 6 each steel wire trough 7 slot away from slightly larger than among steel strand wires with steel wire diameter, after heading
Steel strand wires 8 be caught in the steel wire trough 7 of disc core 6, by spanner twist screw rod on traveling nut 4, drive disc core 6 enter cone
Inside sleeve 1, steel strand wires central hair is drawn by disc core 6 and is caught in inside the cone segments of cone sleeve 1, steel strand wires 8 are locked.
The traction end 3 for drawing breechblock 2 connects traction by the wirerope on hoist engine.Steel strand wires end before steel stranded wire penetrating adapter
(including cut portion) must be wound with adhesive tape and be protected, and prevent steel strand wires end during lashing from dissipating rope.Delayed when lashing by hoist engine
Slowly it draws whole bundle strand line translation and completes whole beam lashing.
The utility model has filled up the blank currently without a kind of auxiliary traction head dedicated for steel strand wires traction, passes through
Simple pier nose processing to steel strand wires, keeps steel strand wires auxiliary traction head lashing convenient, improves construction efficiency.Pass through control simultaneously
Auxiliary traction head diameter and the setting of head taper also have good guarantee to the smooth degree of lashing.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and replacement can also be made, these change
It also should be regarded as the protection scope of the utility model into replacement.
