Abstract

The invention provides a method and device for detecting the steel rail linetype of a railway line. The device can be used for assisting the detection of the linetype of steel rail components of a line. The method for detecting the steel rail linetype of the railway line comprises the following steps: respectively arranging and fixing a cord positioning device and a cord tensioning device on two ends of a steel rail to form two fulcrums for fixing a cord; after the distance from the cord to a steel rail head is adjusted well, tensioning the cord to form a straight line under the tensile force action of a cord wheel, wherein the straight line is used as a reference for detecting straightness; and adjusting the straightness of the steel rail by taking the cord as the reference. The device for detecting the steel rail linetype of the railway line comprises the cord positioning device and the cord tensioning device respectively arranged on the two ends of the steel rail, the cord positioning device and the cord tensioning device are positioned on the two ends of the steel rail by arranging clamps on the bottom of the rail for positioning and adopting three-claw-positioning threaded lead screw for clamping. By means of the method and device provided by the invention, the problem of larger arcs formed during long-distance measurement is solved, and the measurement precision is greatly improved.

Description

Rail track rail line style detection method and checkout gear
Technical field
The invention belongs to field of measuring technique, particularly rail track rail line style detects isolated plant.
Background technology
Along with the continuous development of China railways cause, train running speed is greatly improved.Safe, steady, comfortable in order to ensure train operation just must have high requirement to the line style of rail in the process of deployment of circuit.Article one, rail track be by some rail by being connected and fixed of fastener and switch tie, make it constitute an integral body.In this process, just need some auxiliary checkout equipments, cooperate site operation to lay, rail can be designed with the requirement laying of relevant examination criteria according to drawing finish.Therefore, this checkout equipment is the precision prescribed height on the one hand, requires easy to use and carry on the other hand.In practice of construction in the past, normally with the method detection of straight lines degree or the circular arc degree of backguy rope, this detection means meets requirement easy to use and carry fully, but owing in fixing, do not select suitable benchmark and reliable positioner, thereby locate not accurate enough, and construction time out of doors, owing to the Material Selection of cotton rope and the reason of stretching distance, under the influence of natural wind, it can't be tightened, form big camber line and cause the testing result deviation big, influence quality and efficient that rail track is laid.
Summary of the invention
The object of the invention provides a kind of rail track rail line style detection method and checkout gear, but this device auxiliary detection circuit rail spare line style.
Rail track rail line style detection method, it is to install and fix two cotton ropes of naming a person for a particular job of cotton rope positioner and cotton rope take-up device formation respectively to fix at the two ends of rail, adjust cotton rope after the distance of rail head of rail, under the online tension of taking turns, cotton rope is pulled into a straight line, as the benchmark of detection of straight lines degree, rail is a benchmark with this cotton rope, adjusts the rail straightness accuracy.
Rail track rail line style checkout gear, it is to be made of cotton rope positioner that is installed in the rail two ends respectively and cotton rope take-up device, and cotton rope positioner and cotton rope take-up device all with the flange of rail location that is installed, and adopt three to grab the location and clamp with threaded screw rod in the location at the two ends of rail.
This device is selected for use cotton rope, mainly from cotton rope light weight, little, big 3 considerations of intensity of diameter, finally select the high strength cotton rope for use, pulling force can reach 58.9kg, under the state of tightening, hundred meters maximum actions have solved the big camber line problem that forms when long range measurements in the 3-4mm scope, certainty of measurement is enhanced; Aspect the location,, adopt three to grab the location and clamp with threaded screw rod with the flange of rail location that is installed; Three stability of grabbing have guaranteed the reliable of clamping, and accurate positioning and reliable has been guaranteed in the clamping of threaded screw rod; The tension of cotton rope is that the rotation of armrest handle drive line wheel makes cotton rope reach tension, in the process of backguy, cotton rope is in vacant state not on lateral frame, so just avoid the wearing and tearing of cotton rope on the branch line seat, improved the application life of cotton rope and the degree of tension of cotton rope greatly.
The technology for detection parameter of this device: 100 meters of the longest effective detection distances; The minimum detection precision is less than 0.5mm.
