Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.
The utility model discloses a portable laser string of a thread is used for existing line, high-speed railway switch district section (or sharp district section) work progress specially, short wave irregularity's supplementary construction tool, portable laser collimator also can be called as. As shown in fig. 1, it includes laser emission device 1, two laser targets 2, laser emission device 1 includes laser base 11, laser emitter 12 angle adjustable with laser base 11 top swing joint, laser target 2 includes target holder 21, facula receiving plate 22 is located vertical plane, facula receiving plate 22 sets up the length scale that can follow vertical direction reading or facula receiving plate 22 is provided with the sensor that can detect the facula position, laser base 11 and target holder 21 are embedded to have magnet.
The two laser targets 2 may have the same configuration, and for convenience of description, they are divided into a target 23 fixed at the detection end point and a moving target 24 moving between the detection start point and the detection end point.
The laser transmitter 12 is provided with a protective cover. The laser angle adjusting device can finely adjust the emitting angle, namely the front end of the laser emitter 12 is hinged with the laser base 11, the fine adjustment knob is arranged at the rear end of the laser emitter 12, and the height of the rear end of the laser emitter 12 can be adjusted by rotating the fine adjustment knob, so that the laser angle is adjusted. Preferably, the angle of the laser transmitter 12 can be calibrated or measured by a sensor, so that it can be used for subsequent data processing.
The laser base 11 is provided with a battery compartment, a power switch, an electric quantity display switch and an electric quantity display lamp.
A simpler structure of the spot-receiving plate 22 is: the vertical small flat plate is provided with length scales for reading along the vertical direction on the surface, and when laser spots irradiate the surface of the vertical small flat plate, the laser spots can quickly read.
The measurement of the height and the direction of the steel rail is separately carried out, the reading principle is to read the position of the center of the laser spot in the vertical direction of the scale of the laser target 2, and when the distance between the laser emitting device and the laser target 2 is too close and the center of the laser spot is difficult to identify, the numerical value of the direction of the upper edge and the lower edge of the laser spot can be taken to calculate the center position. The tedious steps of reading the bubble adjusting reference base are avoided, and the working efficiency of track switching is greatly improved. The device has the advantages of simple operation, small volume, convenient carrying, high measurement precision, reliable and simple installation and positioning and convenient use; the on-site construction is convenient, and the operation quality is ensured.
