Embodiment 1

[0032] Such as figure 1 As shown, the hollow main beam 11 between the two rails 12 of the horizontal frame is the mechanism body of the inspection car, on which a supporting traveling mechanism, a tight mechanism, a hand-held push rod 1, a measuring mechanism, a control system, a power supply 28, a display Parts and various sensors, the measuring mechanism mainly includes the gauge measuring mechanism, the mileage measuring mechanism, the height difference measuring mechanism of the two tracks, the control circuit board 27 and the power supply 28 of the control system are installed inside the main girder, and the circuit of the display part Constitute display box 13 with display screen and be installed on main girder 11, main girder is the main component that straddles on two guide rails, and its length is 1464mm, and whole volume is bigger. Its weight and strength should be considered in the design, so it is very important to choose a reasonable section. On the cross-section...

Embodiment 2

[0034] Concrete structure is the same as embodiment 1, as figure 2 As shown, the present invention adopts four idler wheels, which are tightly pressed on the inner sides of the two rails respectively, and one side thereof drives the two idler wheels with two compression springs, which can flexibly compress one side of the rails as the gauge changes. At the same time, the rollers on the same side are pressed against the inner side of the other side rail, so that the verticality of the measuring trolley structure can ensure that the main girder is perpendicular to the rail, so that the measured value reflects the true gauge of the two rails. The distance between the reference wheels is also controlled relatively small, which is required to be 225mm, so the gauge value measured is the average value of the gauge between the two wheels. Therefore, the distance between the two wheels should not be too large, otherwise there will be a large deviation between the measured gauge value...

Embodiment 3

[0036] Concrete structure is the same as embodiment 2, as figure 2 As shown, the mileage measuring wheel is installed at one end, which is equivalent to a cantilever beam, and the force is not very good, so the selection of the bearing is remedied. Double-row radial ball bearings are selected, and the contact surface between the shaft and the inner ring of the bearing is widened, so that the length of the stressed part of the shaft is increased, and it is not easy to cause the shaft to vibrate. more stable.

Abstract

The invention is a portable push-type railway track detection vehicle, which is used to detect the geometric parameters of the rail such as: gauge, superelevation, and triangular pit, including mechanical structure, power supply, induction test, control and display parts, and the mechanical structure is "I" shaped structure, three-point frame. The hollow main girder of the two rails of the horizontal frame is equipped with a supporting traveling mechanism, a tight mechanism, a hand-held push rod, a measuring mechanism, a control system, a power supply, a display box and various sensors. The three rollers and their mechanisms are both supporting and walking mechanism. One side of the abutting mechanism is a positioning roller, and the other side is a retractable pressing roller, so that the main beam is perpendicular to the track and close to the inner side of the rail. The invention not only solves the problems of convenient use, light weight, stable operation, small vibration and corrosion resistance, but also provides a new device for realizing dynamic continuous measurement, high measurement accuracy, good rigidity, and stable reference plane. The structure is light and simple, The concept is novel, the operation is convenient, and it can be put into industrial application quickly.

Description

technical field [0001] The invention relates to the installation quality detection of rails in railway transportation, mainly relates to the geometric parameter quality detection equipment of the rails, specifically a new type of portable push-type railway rail detection vehicle. Background technique [0002] The track line is the basic part of railway transportation, and its basic geometric parameters such as gauge, superelevation, and triangular pit are correct or not, which are of great significance to ensure the safety of railway traffic. [0003] Irregularity of the track can reduce the service life of the track and locomotives, reduce passenger comfort, and endanger driving safety, causing vicious driving accidents such as derailment and overturning, and bringing huge property and life losses to passengers. The major event of the day is also the top priority of the railway transportation department. [0004] The speed of railway transportation is increasing again and ...
