Line is connected, and anticreep stomidium is placed on the anticreep neck of the leveling end plate of clamping device and prevents it from falling off.Connection sleeve to clamp
Device each section can form an entirety, and flexural pivot closed protective is got up, and prevent dirt from entering and influence flexural pivot rotation.
The leveling end plate is by flexural pivot pedestal, anticreep neck and bearing end board group at flexural pivot pedestal and the ball for adjusting long screw
The stomidium set of the connection sleeve of hinge head formation spherical hinge structure, anticreep neck and clamping device is even to which formation can turn in a certain range
Dynamic entirety, the loading end for carrying end plate is the rough surface of the forms such as embossing, to increase the frictional resistance with structure stress face.
Provided by the present invention for the clamping device that ballastless track structure is laterally rectified a deviation, realized using sleeve-screw structure
The length adjustment of clamping device can adapt to the variation and chucking power of counterforce structure (position limiting structure) and track structure spacing
Variation.Realizing clamping device using spherical hinge structure can freely adjust the angle in a certain range, can adapt to clamping device
The not parallel operating condition of structure on two sides stress surface.The design combined using multi-part, significantly reduces execute-in-place workload.Lightly
And compact structure reduces weight under the premise of assurance function, improves operation ease.
In conclusion the clamping device of the present invention laterally rectified a deviation for ballastless track structure, for no tiny fragments of stone, coal, etc. rail
Have the characteristics that economical and efficient, safe and reliable, tissue is flexible when the correction of road structure, it is ensured that peace of driving a vehicle during Deviation Correction Construction
Complete and equipment safety, application prospect are good.

Specific embodiment
With reference to the accompanying drawings by specific embodiment, the device of offer of the invention is further illustrated.
The clamping device provided in an embodiment of the present invention laterally rectified a deviation for ballastless track structure includes adjusting long sleeve 1, adjusting
Long screw 2, connection sleeve 3 and leveling end plate 4.
Before implementing ballastless track structure and laterally rectifying a deviation, four parts of the clamping device are subjected to assembly and connection.
Specific assembly and connection mode are as follows: by the inner thread sleeve 1-2 for adjusting long sleeve 1 and the external screw thread screw rod 2-1 of long screw 2 is adjusted to pass through silk
Button connection；The connection external screw thread 2-3 of long screw 2 will be adjusted to pass through screwed connection with the connection internal screw thread 3-1 for connecting sleeve 3；It will be even
The anticreep stomidium 3-2 of female connector cylinder 3 is placed at the anticreep neck 4-2 of leveling end plate 4, then carries out the anticreep neck of leveling end plate 4
The weldering of the carrying end plate 4-3 of 4-2 and leveling end plate 4 connects.
It, will even when needing to carry out track structure laterally clamping limit during implementing ballastless track structure and laterally rectifying a deviation
It is connected in whole clamping device to be put between counterforce structure and track structure, adjusts long sleeve 1 and tune long screw 2 to be formed by screwing
Sleeve-screw structure adjustment clamping device length, make adjust long sleeve 1 carrying end plate 1-1 act on counterforce structure work
On face, while the carrying end plate 4-3 for leveling end plate 4 being made to act on track structure side.
Two spanners are separately mounted on the outer-hexagonal head 2-2 for adjusting the bayonet 1-3 of long sleeve 1 and tune long screw 2, are passed through
Artificial reinforcing is adjusted in length and chucking power of the spanner to clamping device, presss from both sides to realize to the transverse direction of ballastless track structure
Hold constraint.
When the track structure side of counterforce structure working face and corresponding position is not parallel and in a certain angle, long screw is adjusted
The angle for the spherical hinge structure meeting adjust automatically clamping device that 2 flexural pivot head 2-4 and the flexural pivot pedestal 4-1 of leveling end plate 4 are formed, from
And it is anti-to keep adjusting the working face of the carrying end plate 1-1 of long sleeve 1 and the carrying end plate 4-3 of leveling end plate 4 and two sides to be clamped
Power structure and track structure acting surface come into full contact with, and keep uniform force, and stress concentration is avoided to lead to clamped works coagulation
Soil damage and clamping device hold curved damage.
After correction section ballastless track structure permanently restores track structure lateral stability, the clamping dress under disassembly
It sets wait reuse.
