Description
Technical field
The present invention relates to a kind ofly both be convenient for carrying, be convenient to again to detect and rail track rail line style inspection checkout gear and detection method that accuracy of detection is high relatively, belong 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 through 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 accomplish.Therefore, this checkout equipment precision prescribed on the one hand is high, 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 localization device; Thereby locate not accurate enoughly, in and construction time out of doors, is owing to the Material Selection of cotton rope and the reason of stretching distance; Under the influence of natural wind; Can't it 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
Purpose of design: provide a kind of and both be convenient for carrying, be convenient to again to detect and rail track rail line style checkout gear and detection method that accuracy of detection is high relatively, but this device auxiliary detection circuit rail spare line style.
Design scheme: the application is a benchmark with tested rail two ends, through the adjusting of adjusting rod, cotton rope is equated with the distance of rail two ends rail head, is benchmark with this cotton rope then, through the distance of adjustment rail and cotton rope, and control rail line style.On structure design, this covering device is to be made up of active line transfer clamping mechanism and passive line transfer clamping mechanism, and two parts constitute; Be mounted on the two ends of rail respectively, form two cotton ropes of naming a person for a particular job and fix, under the final 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.The setting drawing of two covering devices is seen Fig. 2 and Fig. 3 respectively.Selecting for use of cotton rope mainly from cotton rope light weight, little, big 3 considerations of intensity of diameter, finally selected the high strength cotton rope for use, and pulling force can reach 58.9kg, and under the state of tightening, hundred meters maximum actions are in the 3-4mm scope.
Technical scheme: rail track rail line style inspection checkout gear; Initiatively line transfer clamping mechanism and passive line transfer clamping mechanism constitute; Initiatively the line transfer clamping mechanism on the line wheel, twines an end of cotton rope it is tightened through rotation, and the support through the line transfer bar; Make it be in rail head of rail and reduce 14-18mm place, the distance of regulating cotton rope and rail head of rail simultaneously; Passive line transfer clamping mechanism is fixed an end of cotton rope and the support through the line transfer bar, makes it be in rail head of rail and reduces 14-18mm place, the distance of regulating cotton rope and rail head of rail simultaneously.Detection method: this checkout gear is by mechanism 1 and mechanism's 2 common detections of accomplishing the rail line style.In the mechanism 1, the line wheel is connected with the hole spot welding of ratchet adopting process, and the synchronizing wire winding wheel shaft rotates, and utilizes the characteristics of the unidirectional positioning of rotating of ratchet device, and cotton rope is tightened.Fixed connection plays in 2 pairs of another terminations of cotton rope in mechanism.Adopt backguy to detect the principle that the rail line style has been selected 2 definite straight lines for use; With two ends, rail district to be detected is benchmark; Respectively at two ends definite from the equidistant space of rail head of rail 2 points; Forming straight line in the space, is benchmark with this straight line at last, confirms the rail line style according to the distance between rail head of rail and the cotton rope.The detection step is following:
The first step, mechanism 1,2 is installed on the two ends place in rail zone to be detected respectively;
Line wheel in second step, the rotating mechanism 1 makes cotton rope be in tight state;
Adjusting rod on the 3rd step, the guiding mechanism 1,2 makes two fixed end cotton ropes and rail head of rail reduce 16mm place distance and equates;
The 4th step, detect cotton rope with board foot and reduce 16mm place distance, adjust the rail line style with rail head of rail.
The present invention compares with background technology, and the one, because cotton rope adopts the high strength cotton rope, solved the big camber line problem that when long range measurements, forms, certainty of measurement is enhanced; The 2nd, aspect the location, make dop according to the rail head of rail profile, when being installed, utilize fastener shaft that dop is clamped on the rail head, the cotton rope adjusting rod is arranged in the side, make cotton rope be in rail head of rail and reduce the 16mm place; The 3rd, the application has realized the longest 100 meters of the distances that effectively detect; The minimum detection precision is less than 0.5mm.
