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 main body of the inspection vehicle, on which the supporting walking mechanism, the abutting mechanism, the hand-held push rod 1, the measuring mechanism, the control system, the power supply 28, and the display are installed. Part 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 beam, and the circuit of the display part The display box 13 formed with the display screen is installed on the main beam 11, the main beam is the main part spanning two guide rails, its length is 1464mm, and the whole volume is relatively large. The weight and strength must be considered in the design, so it is very important to choose a reasonable secti...

Embodiment 2

[0034] The specific structure is the same as in embodiment 1, such as figure 2 As shown, the present invention adopts four supporting wheels, which are respectively tightly pressed on the inner side of two steel rails, one side of which is driven by two compression springs, which can stretch and contract one side of the steel rail with the change of the gauge. At the same time, the wheel on the same side is pressed against the inner side of the rail on the other side, so that the verticality of the trolley structure can be measured to ensure that the main beam 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 to be relatively small, which is required to be 225mm, so the measured gauge value is the average of the gauge between the two wheels. Therefore, the distance between the two supporting wheels cannot be too large, otherwise the measured gauge value and the mileage po...

Embodiment 3

[0036] The specific structure is the same as in embodiment 2, such as figure 2 As shown, the mileage measuring wheel is installed at one end, which is equivalent to a cantilever beam, and the stress is not very good, so remedial measures are taken in the selection of the bearing. Double-row radial ball bearings are selected to widen the contact surface between the shaft and the inner ring of the bearing, so that the length of the stressed part of the shaft is increased, and it is not easy to cause the shaft to vibrate, which ensures that the mileage measuring wheel does not jump when it is rotating, and the trolley is running China is more stable.

Abstract

This invention relates to a portable pushing car for checking railway, with such geometric parameter as railway gage, cant, triangle pit, including mechanical structure in I-shaped and three-point framework, electric source, induction testing, controlling and displaying sections. The bearing bogie structure, closing structure, hand button rod, measuring mechanism, controlling system, electric source, displaying box and various sense organs are mounted on main beam crossed on two-railway, three rollers and their mechanism which is both bearing and bogie. On one side of closing mechanism there is position closing wheel, on the other side there is retractable pressure resistant wheel used to make king piece and railway erect, and close to the inside of the railway. This advantages are light weight, stability, slight shaking and corrosion resistance.

Description

Technical field [0001] The invention relates to the installation quality detection of rails in railway transportation, and mainly relates to the geometric parameter quality detection equipment for the rails, and specifically, it is a new type of portable and push-type railway track detection vehicle. Background technique [0002] Track line is the basic part of railway transportation, and its basic geometric parameters such as: gauge, superelevation, and triangle pit are correct or not to ensure the safety of railway traffic. [0003] The unevenness of the track can reduce the life of the track and rolling stock, reduce the comfort of passengers, and endanger the driving safety, causing derailment, subversion and other vicious driving accidents, causing huge loss of property and life to passengers, which is a life-threatening situation. The major event of the sky is also the top priority of the railway transportation department. [0004] The speed of railway transportation is inc...
