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 it is to solve the problems, such as that the steel strand wires gone out at present to tensioning in tension steel strand are unprotected and design.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 of lower frame and right relief angle, 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 shields, 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 axis pin；Upper ledge is equipped with handrail.Advantage is to protect the steel strand wires that tensioning goes out.
Description
Technical field：
The present invention relates to a kind of protective devices of Bridge Rotation Construction Technique steel strand wires.
Background technology：
All it is then two tensioning by being arranged symmetrically by steel strands wound on turntable in existing highway bridge rotator construction
Jack tension steel strand wires realize turntable rotation to realize bridge rotating.In tension steel strand, steel that usually tensioning is gone out
Twisted wire does not carry out necessary protection, and there are two the drawbacks of doing so, first, if fracture of wire, steel occur in steel strand wires in stretching process
Twisted wire 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 on the ground,
Ground can be inserted into due to steel strand wires end influences stretch-draw effect to influence Bridge Rotation Construction Technique.For the second situation, sometimes
Steel plate can be opened in stretching process middle berth one prevents steel strand wires to be inserted into ground on the ground, although doing so can avoid steel strand wires from being inserted into
Ground, but since there are frictional force between steel strand wires and steel plate, steel strand wires forward movement can be influenced, to influence bridge rotating
Stretching construction.
Invention content：
Technical problem to be solved by the invention is to provide one kind can guarantee steel strand tension construction safety in Bridge Rotation Construction Technique,
Ensure the protective device of the Bridge Rotation Construction Technique steel strand wires of Bridge Rotation Construction Technique quality.
What above-mentioned purpose was realized in：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
The both ends of brace and the second brace, the first brace are respectively welded at the left-front corner of lower frame and right relief angle, 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 shields, front apron, rear baffles, under the lower ends of two side shields, front apron
End 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；Further include cover board, cover board passes through
The top that axis pin is mounted on rear baffle is just placed on two side shields when the closure is closed；Upper ledge is equipped with handrail.
It is an advantage of the invention that：When construction, open cover board, steel strand wires be put into device, cover cover board, steel strand wires be from
Gap between front apron and cover board passes through, and with the progress of tensioning, steel strand wires push protective device slowly to move forward, until bridge
After the angle stopping tensioning for turning design, device also stops moving.After turntable sealing is good, you can fill steel strand wires from protection
Middle taking-up is set, device remains to reuse.
The present apparatus can protect the steel strand wires that tensioning goes out, it is ensured that steel strand tension is constructed in Bridge Rotation Construction Technique
Safety, simultaneously because its own, with wheel, can flexibly move, reduce between steel strand wires and ground under external force
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.
Description of the drawings：
Fig. 1 is the main structure diagram of the present invention；
Fig. 2 is the A-A views of Fig. 1；
Fig. 3 is the side structure schematic view of the present invention.
Specific implementation mode：
Below according to Fig. 1-3, the present invention will be further described；
It includes frame, and frame includes lower frame 1 and upper ledge 2, and four traveling wheels 3 are mounted on the four of lower frame by respective axis respectively
On a angle；Lower frame is welded by two sheer poles and two lower vertical bars, further includes the first brace 4 and the second brace 5, and
The both ends of one brace are respectively welded at the left-front corner of lower frame and right relief angle, and the both ends of the second brace are respectively welded at lower frame
Right anterior angle and left rear corner；Upper ledge is welded by two cross tubes and two upper vertical bars；Upper ledge and lower frame pass through several upright bars 6
And several braces 7 link together；
Bottom plate 8 is placed on lower frame, further includes two side shields 9, front apron 10, rear baffle 11, the lower end of two side shields, front
The lower end of plate 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；Further include cover board 12,
The top that cover board is mounted on rear baffle by axis pin is just placed on two side shields when the closure is closed；Upper ledge is equipped with and helps
Hand 13.
