Abstract
The utility model provides a single freedom degree fine-tuning pawl for paving a rail traffic international summit (CRTS II) type ballastless track slab, which is characterized by comprising a ground angle seat, wherein the ground angle seat is provided with a slide block, the lower end of the slide block is provided with an idler wheel and is arranged on the ground angle seat in a sliding way, the upper end of the slide block is provided with a vertical screw rod, the vertical screw rod is sheathed with a square screw nut, a ballastless track slab support bracket is fixed on the vertical screw rod by the square screw nut, and the bottom of the vertical screw rod is hemispheric to be hinged with the slide block. The single freedom degree fine-tuning pawl for paving the CRTS II type ballastless track slab is reasonable in design and can be used with other fine-tuning pawls, so that the interference constraints when the track slab is finely tuned can be effectively eliminated, the labor intensity is low, the adjusting speed is fast, the adjusting precision is high, and the quantity of required operating people is small, and therefore, the single freedom degree fine-tuning pawl not only can be manually adjusted but also can be automatically adjusted.
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 single-degree-of-freedom accurate adjustment pawl of realizing that automation, mechanization are 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.
CRST II type fragment-free track slab manual setting equipment of the prior art, all manual settings are adjusted up and down and will be screwed with long-arm wrench, and have added interference constraints on four adjustment point vertical directions, can not 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 provides a kind of reasonable in design, CRTS II type fragment-free track slab pavement single-degree-of-freedom accurate adjustment pawl that can be used with other accurate adjustment pawl, interference constraints when it can effectively eliminate track slab precision adjustment, labour intensity is low, regulate the speed fast, adjustment precision height, action required personnel are few, artificial adjustment can be applied to, the automation adjustment can be realized 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 single-degree-of-freedom accurate adjustment pawl, it is characterized in that described accurate adjustment pawl comprises a ditch seat, on this ditch seat a slide block is set, this slide block lower end is provided with roller and rolls and is arranged on the seat of ditch, this upper end of slide block is provided with vertical screw rod, this a vertical screw rod and a square nut socket, and square nut is fixed on the fragment-free track slab bracing frame on the vertical screw rod, vertical screw rod bottom is a hemispherical, and is hinged with slide block.
In the specific embodiment, described slide block comprises roller support, and two rollers walk abreast and are arranged on the roller support by axle with holes, and the two ends of axle with holes are provided with fixedly uses jump ring.
In one embodiment, described axle with holes is that two ends are with holes, and this hole is the oilhole that refuel the way roller the inside.
In another embodiment, described fragment-free track slab bracing frame is the L type, is distributed in the square nut left and right sides, directly contacts with CRT II type fragment-free track slab to be connected.
In the embodiment, the lower surface of described ditch seat is provided with the base fixed part of teeth groove again.
This CRTS II type fragment-free track slab pavement single-degree-of-freedom accurate adjustment pawl utilizes roller to realize the free adjustment of the rolling member of X axis direction, adopt vertical screw rod to realize the noiseless constraint adjusting of vertical direction, can adopt servomotor control virtual displacement and is connected at vertical direction, realize adjustment freely by slide block and roller in the horizontal direction with track plate elasticity.
The beneficial effects of the utility model are, this CRTS II type fragment-free track slab pavement single-degree-of-freedom accurate adjustment pawl is reasonable in design, can be used with other accurate adjustment pawl, interference constraints when it can effectively eliminate track slab precision adjustment, labour intensity is low, regulate the speed fast, adjustment precision height, action required personnel are few, can be applied to artificial adjustment, can realize the automation adjustment again.
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
