Abstract
The protective device of Bridge Rotation Construction Technique steel strand wires is related to a kind of protective device of Bridge Rotation Construction Technique steel strand wires.Mainly designed to solve the problems, such as unprotected to the steel strand wires of tensioning out in tension steel strand at present.It includes frame, and frame includes lower frame and upper ledge, and traveling wheel is by axis on lower frame；Lower frame is welded by two sheer poles and two lower vertical bars, further includes the first brace and the second brace, and the both ends of the first brace are respectively welded at the left-front corner and right relief angle of lower frame, and the both ends of the second brace are respectively welded at the right anterior angle and left rear corner of lower frame；Upper ledge is welded by two cross tubes and two upper vertical bars；Upper ledge and lower frame are linked together by upright bar and brace；Bottom plate is placed on lower frame, and the lower end of the lower end of two side baffles, the lower end of front apron and rear baffle is all fixed with bottom plate, and cover board is mounted on the top of rear baffle by pin shaft；Upper ledge is equipped with handrail.Advantage is that the steel strand wires that can go out to tensioning protect.
Description
Technical field:
The utility model relates to a kind of protective devices of Bridge Rotation Construction Technique steel strand wires.
Background technique:
It is all then to pass through two be arranged symmetrically by steel strands wound on turntable in existing highway bridge rotator construction
Stretch-draw jack tension steel strand realizes turntable rotation to realize bridge rotating.In tension steel strand, usually tensioning is gone out
Steel strand wires the drawbacks of not carrying out necessary protection, doing so there are two, first is that if steel strand wires break in stretching process
Silk, steel strand wires can scurry out, and be easy to cause safety accident；Second is that in stretching process, since the steel strand wires that tensioning goes out are placed directly in
On the ground, stretch-draw effect can be influenced to influence Bridge Rotation Construction Technique due to steel strand wires end insertion ground.For second situation,
Steel plate is opened on the ground to prevent steel strand wires to be inserted into ground, although steel strand wires can be avoided by doing so in stretching process middle berth one sometimes
It is inserted into ground, but since there are frictional force between steel strand wires and steel plate, will affect steel strand wires forward movement, to influence bridge
Turn stretching construction.
Summary of the invention:
The technical problem to be solved by the utility model is to provide one kind can guarantee steel strand tension in Bridge Rotation Construction Technique
Construction safety, it is ensured that the protective device of the Bridge Rotation Construction Technique steel strand wires of Bridge Rotation Construction Technique quality.
Above-mentioned purpose is achieved in that it includes frame, and frame includes lower frame and upper ledge, and four traveling wheels pass through respectively
Respective axis is mounted on four angles of lower frame；Lower frame is welded by two sheer poles and two lower vertical bars, further includes first
Brace and the second brace, the both ends of the first brace are respectively welded at the left-front corner and right relief angle of lower frame, the second brace
Both ends be respectively welded at the right anterior angle and left rear corner of lower frame；Upper ledge is welded by two cross tubes and two upper vertical bars；On
Frame and lower frame are linked together by several upright bars and several braces；
Bottom plate is placed on lower frame, further includes two side baffles, front apron, rear baffles, the lower end of two side baffles, front apron
Lower end and the lower end of rear baffle all fixed with bottom plate, the height of front apron is less than the height of rear baffle；It further include cover board, cover board
It is mounted on the top of rear baffle by pin shaft, when the closure is closed, is just placed on two side baffles；Upper ledge is equipped with handrail.
The utility model has the advantages that: when construction, cover board is opened, steel strand wires are put into device, cover board, steel strand wires are covered
It is that gap between front apron and cover board passes through, with the progress of tensioning, steel strand wires push protective device slowly to move forward, until
After the angle of bridge rotating to design stops tensioning, device also stops moving.It, can be by steel strand wires from anti-after turntable sealing is good
It is taken out in protection unit, device remains to reuse.
The steel strand wires that the present apparatus can go out tensioning protect, it is ensured that steel strand tension is constructed in Bridge Rotation Construction Technique
Safety, simultaneously because its own, with wheel, can flexibly move under external force, reduce between steel strand wires and ground
Frictional force, it is ensured that the quality of Bridge Rotation Construction Technique.And it is easy for installation, it is easy to operate, it can reuse, economize on resources.
Detailed description of the invention:
Fig. 1 is the schematic view of the front view of the utility model；
Fig. 2 is the A-A view of Fig. 1；
Fig. 3 is the side structure schematic view of the utility model.
Specific embodiment:
It is described further below according to 3 pairs of the utility model of Fig. 1-；
It includes frame, and frame includes lower frame 1 and upper ledge 2, and four traveling wheels 3 are mounted on lower frame by respective axis respectively
Four angles on；Lower frame is welded by two sheer poles and two lower vertical bars, further includes the first brace 4 and the second brace
5, the both ends of the first brace are respectively welded at the left-front corner and right relief angle of lower frame, and the both ends of the second brace are respectively welded at down
The right anterior angle and left rear corner of frame；Upper ledge is welded by two cross tubes and two upper vertical bars；Upper ledge and lower frame pass through several
Upright bar 6 and several braces 7 link together；
Bottom plate 8 is placed on lower frame, further includes two side baffles 9, front apron 10, rear baffle 11, the lower end of two side baffles,
The lower end of front apron and the lower end of rear baffle are all fixed with bottom plate, and the height of front apron is less than the height of rear baffle；It further include lid
Plate 12, cover board are mounted on the top of rear baffle by pin shaft, when the closure is closed, are just placed on two side baffles；On upper ledge
Equipped with handrail 13.
