| titleOfInvention | Measuring trolley for railway platform clearance |
| abstract | The utility model discloses a be used for railway platform limit to measure dolly, this measurement dolly essential element is by the wheel pair, press from both sides tight centering mechanism, the bearing support, the aluminium alloy connecting piece, gasoline generator device, synchronous belt drive, including a motor, an end cap, a controller, and a cover plate, seat, basic brake mechanism, laser and grating sensor device, the display screen, the pneumatic cylinder is constituteed, wherein press from both sides tight centering mechanism by the contact wheel, the contact wheel pin, the catch bar, basic brake mechanism is by the brake shoe, the brake shoe cover, the brake beam, the brake pull rod, the roll axis, lower depression bar, fixed pivot is constituteed. When the platform clearance is measured, a non-contact space measurement scheme is adopted, the laser sensor is used for realizing distance measurement, the grating is used for realizing angle measurement, the horizontal and vertical distances of the railway platform clearance are obtained by utilizing a trigonometric function, the measurement mode is improved substantially, the measurement efficiency and the measurement precision are greatly improved, the operation is convenient, and the automation degree is high. |
