Abstract
The utility model relates to a railway line steel rail line type detection device which is convenient to carry, detect and has relatively high detection precision, which comprises an active line adjusting clamping mechanism and a passive line adjusting clamping mechanism, wherein the active line adjusting clamping mechanism winds one end of a cotton rope on a line wheel, tightens the line wheel through rotary winding, and is positioned at a position where the steel rail head is reduced by 14-18mm through the support of a line adjusting rod, and simultaneously adjusts the distance between the cotton rope and the steel rail head; one end of the cord is fixed by the passive cord adjusting and clamping mechanism and is positioned at the position where the rail head of the steel rail is lowered by 14-18mm through the support of the cord adjusting rod, and meanwhile, the distance between the cord and the rail head of the steel rail is adjusted. The advantages are that: firstly, the problem of a large arc line formed in long-distance measurement is solved because the wire rope is a high-strength wire rope, and the measurement precision is greatly improved; and secondly, manufacturing a clamping head according to the outline of the rail head of the steel rail, clamping the clamping head on the rail head by using a fastening shaft when the clamping is installed, and arranging a wire rope adjusting rod on the side surface.
Description
Technical field
The utility model relates to and a kind ofly both being convenient for carrying, and is convenient to again to detect and rail track rail line style inspection checkout gear that accuracy of detection is high relatively, belongs to field of measuring technique, and 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.
The utility model content
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 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.
The utility model is compared 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.
