Description
Technical field
The utility model relates to a kind of rail bending offset distance and gage line linearity laser assisted detector that is used for rail bending offset distance and the detection of gage line linearity, belongs to rail bending offset distance and gage line linearity detector and makes the field.
Background technology
Form in the rail spare of track switch, remove guide rail and straight stock rail, institute's rail spare all need carry out bending.Track switch is produced and is adopted the manual stretch-draw string of a musical instrument (shown in the graticule in the accompanying drawing 2) to detect the method for rail bending offset distance (as y value in the accompanying drawing 2) at present, carry out rail spare bending offset distance and repair accent, rail bending segment length is in less than the 5m scope, detecting error is ± 3mm, rail bending segment length is in less than the 10mm scope, and the detection error is ± 5mm.Its weak point: background technology adopts by hand carries out big, the inefficient defective of stretch-draw string of a musical instrument error, and not only detection means is backward, efficient is low, error is big, and can't satisfy the especially batch production requirements of large size code channel trouble of existing track switch.
Summary of the invention
Purpose of design of the present utility model is: by improving existing detection method, develop novel rail spare bending and prop up the pick-up unit that device for detecting distance substitutes existing backwardness, reach and enhance productivity, the purpose of the product quality of keeping under strict control.
Design proposal of the present utility model is: a novel rail bending top device for detecting distance distribution injection device of development, receive (with reading) device two parts, emitter utilizes optical principle, with the rail flat segments is benchmark, launch the parallel beam parallel with datum line, after by the receiving trap that is installed in bending segment this light source being handled, the place draws reading at the digital display vernier, its generating laser is fixed on the pedestal, the parallel beam that emission is parallel with rail flat segments 3, after the light source processing of receiving trap to parallel beam, the angle of regulating receiving trap vernier guide rail according to the light source result is fixing to vertical back with parallel beam, draws reading according to the digital display vernier.
Technical scheme: rail bending offset distance and gage line linearity laser assisted detector, constitute by laser beam emitting device and laser pick-off and reading device, generating laser in the laser beam emitting device is fixed on the generating laser pedestal, light beam in the laser receiver receives the digital display vernier and is enclosed within on the vernier guide rail, and the guide rail axis of rotation during the vernier guide rail passes guide rail level angle adjusting gear and is fixed on the laser receiver pedestal is connected and can carries out the horizontal direction rotation to be adjusted to the vernier guide rail vertical with parallel beam.
The utility model is compared with background technology, and the one, the rail bending offset distance detection applicable to the various form of fractures in home and abroad is applicable to the detection of rail flatness simultaneously; The 2nd, it is low fundamentally to have solved the manual string of a musical instrument detection method efficient that background technology exists, and the shortcoming that error is big can be brought up to accuracy of detection ± 0.5mm by ± 5mm; The 3rd, convenient reading, simply should operate, can realize one man operation.
Description of drawings
Fig. 1 is the structural representation of rail bending offset distance and gage line linearity laser assisted detector.
Fig. 2 is the structural representation of background technology.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.Rail bending offset distance and gage line linearity laser assisted detector are made of laser beam emitting device 2 and laser pick-off and reading device 1, generating laser 2-2 in the laser beam emitting device 2 is fixed on the generating laser pedestal 2-1, is equipped with magnet at generating laser pedestal 2-1 and the rail web of the rail, rail's end portion contact site.Light beam in the laser receiver 1 receives digital display vernier 1-1 and is enclosed within on the vernier guide rail 1-2, vernier guide rail 1-2 passes the lower end digital display vernier base 1-3 and is connected with guide rail axis of rotation 1-4 and can carries out horizontal direction and rotate and to be adjusted to vernier guide rail 1-2 and parallel beam 5 vertical (rail bends offset distance check point 6), and the laser receiver pedestal 1-3 and the rail web of the rail, rail's end portion contact site are equipped with magnet.That is to say that laser beam emitting device and laser receiver all adopt magnetic to fix, after earlier emitter being fixed, the back draws reading after receiving end is regulated receiving trap, can realize one man operation.Its detection method: laser beam emitting device 2 is adsorbed on the rail flat segments 3 by the magnet of its generating laser base bottom, laser receiver 1 is adsorbed on the rail bending segment 4 by the built-in magnet of its laser receiver pedestal 1-3, the parallel beam 5 that generating laser 2-2 in the laser beam emitting device 2 emission and rail flat segments 3 are parallel, light source by 1 pair of parallel beam 5 of laser receiver is handled automatically, according to the light source result, angle and the vertical back with parallel beam of regulating vernier guide rail 1-2 in the laser receiver are fixing, the digital display vernier can draw the detection reading, it detects the offset distance scope is 0.5～350mm, horizontal range 0～30m detects error and is ± 0.5mm can examining in the scope.
What need understand is: though the foregoing description is to the utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
