Abstract
The utility model discloses a double-freedom degree fine-tuning claw for paving CRTS II type ballastless track boards, which is characterized in that the fine-tuning claw comprises a pitch seat; a traverse sliding block is movably arranged on the pitch seat, is driven and connected by a traverse adjusting screw rod, and is connected with a vertical screw rod; the vertical screw rod is in sleeve joint with a square nut which is fixed on a support frame of a CRTS II type ballastless track board; the bottom of the vertical screw rod is hemispherical; and the vertical screw rod is hinged with the traverse sliding block. The double-freedom degree fine-tuning claw for paving the CRTS II type ballastless track boards is reasonable in design, low in labor intensity and high in adjusting speed and adjusting precision, needs few operating personnel, and not only can be applicable to manual adjustment, but also can realize automatic adjustment.
Description
Technical field
The utility model belongs to ballastless track of high-speed railway engineering construction adjuster, is specifically related to a kind of CRTS II type fragment-free track slab pavement double freedom accurate adjustment pawl of realizing that mechanization is regulated.
Background technology
At present, along with the develop rapidly of high-speed railway, plate-type ballastless track is widely used, and plate-type ballastless track has the comprehensive construction investment economy, manufactured precision and production efficiency height, is convenient to advantages such as control, adjustment and reparation by millworkization.Non-fragment orbit as the rich lattice plate-type ballastless track system based on Germany grows up comprises concrete bed under the plate, parts such as CA mortar bed, track plate, long rail and fastener.
CRTS II type fragment-free track slab manual setting equipment of the prior art, all manual settings, adjust up and down and will screw with long-arm wrench, and horizontal direction is adjusted into unidirectional thread screw adjustment, there is the gap in it when oppositely adjusting, particularly the error that produces because of wearing and tearing reaches several millimeters, is difficult to realize automation.There is following shortcoming at least in above-mentioned present technology: labour intensity is big, it is slow to regulate the speed, adjust that precision is low, operating personnel are many, be difficult to realize automation mechanized operation.
The utility model content
The purpose of this utility model provide a kind of reasonable in design, labour intensity is low, regulate the speed CRTSII type fragment-free track slab pavement double freedom accurate adjustment pawl fast, it adjusts the precision height, action required personnel are few, can be applied to artificial adjustment, can realize the automation adjustment again.
The purpose of this utility model is achieved through the following technical solutions:
A kind of CRTS II type fragment-free track slab pavement double freedom accurate adjustment pawl, it is characterized in that described accurate adjustment pawl comprises a ditch seat, activity is provided with a transverse slider on this ditch seat, this transverse slider is connected by a lateral adjustments screw drive, this transverse slider connects a vertical screw rod, this a vertical screw rod and a square nut socket, and square nut is fixed on the II type fragment-free track slab bracing frame, vertical screw rod bottom is a hemispherical, and is hinged with transverse slider.
In one embodiment, described lateral adjustments screw rod is arranged on the seat of described ditch, and this lateral adjustments screw rod is forward and reverse two-flight screw.
In one embodiment, the movable setting-in of described transverse slider is arranged in the chute of seat upper surface, ditch.
In one embodiment, be threaded by one group between described lateral adjustments screw rod and ditch seat, this lateral adjustments screw rod is connected by another group screw drive with slide block, and these two groups of screw threads are reverse thread.
In another embodiment, the top of described vertical screw rod is provided with a square nut, and this square nut is fixedly connected on II type fragment-free track slab bracing frame on the vertical screw rod.
In the embodiment, described II type fragment-free track slab bracing frame is shaped as the L type, is distributed in the square nut left and right sides again, directly contacts with II type fragment-free track slab to be connected.
In the another embodiment, the lower surface of described ditch seat is provided with the base fixed part of teeth groove.
This CRTS II type fragment-free track slab pavement double freedom accurate adjustment pawl can adopt forward and reverse two-flight screw straight line to regulate in the horizontal direction, eliminate the error that produces when common single thread straight line is regulated, particularly reach several millimeters error, really realized and accurately to have controlled adjustment with servomotor because of what wearing and tearing produced; Adopt regular screw threads control at vertical direction, also can drive and realize automation with servomotor.The lateral adjustments screw rod is opposite with the matching thread direction of transverse slider and base element, can realize easily the driving of transverse slider is regulated.
This CRTS II type fragment-free track slab pavement double freedom accurate adjustment pawl has significantly improved CRTS II type not to be had the laying automaticity of track plate how and lays efficient, satisfies the laying needs of high-speed railway Line for Passenger Transportation.This double freedom accurate adjustment pawl is specially adapted to not have the accurate governor motion automatically of track plate how, and the advantage that can realize that labour intensity is low, regulate the speed fast, adjust the precision height, operating personnel is few is easy to realize full-automatic the adjustment.
The beneficial effects of the utility model are, this CRTS II type fragment-free track slab pavement double freedom accurate adjustment pawl is reasonable in design, labour intensity is low, regulate the speed fast, and it adjusts the precision height, and action required personnel are few, artificial adjustment can be applied to, the automation adjustment can be realized again.
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
