Description

Technical Field

[0001] This invention relates to a detection system for high-speed railway platforms, and more particularly to a detection system for safety control parameters of high-speed train passage on high-speed railway platforms. Background Technology

[0002] With the continuous growth of my country's high-speed rail operating mileage and high frequency of train services, the number of platforms and the workload of inspections have increased dramatically. Traditional manual inspections are insufficient to cover the regular inspection needs of the massive number of stations. High-speed rail operates at high speeds, and even minor deviations in parameters such as track gauge, platform clearance, canopy clearance, and tunnel clearance can lead to accidents. Therefore, regular inspections of high-speed rail platform clearance, canopy clearance, and other clearance parameters are necessary, in accordance with the requirements of the railway's integrated "human, physical, and technical" safety assurance system.

[0003] Currently, track gauge is measured manually using mechanical or digital gauge rulers; platform clearance is checked using digital clearance rulers or aluminum alloy rulers, with horizontal distances (from track center to platform edge) and heights (from track surface to platform surface) measured point by point. Canopy clearance and tunnel clearance can be measured using laser measuring instruments. Using different instruments not only results in low inspection efficiency but also requires recording measurement data after each measurement, making the process prone to errors. Furthermore, the accuracy of manually measured data needs further improvement. (Invention Content) The purpose of this invention is to address the deficiencies of the existing technology by providing a high-speed rail platform train passage safety control parameter detection system. This system can quickly detect the distance from a point on the side elevation of the high-speed rail platform to the perpendicular bisector of the rail surface, the distance from a point on the edge of the platform top surface to the rail surface, and the dimensions of the canopy and tunnel clearance, thereby effectively improving detection efficiency and accuracy.

[0004] The technical solution adopted by this invention to achieve the above objectives is as follows: a high-speed rail platform train passage safety control parameter detection system, comprising a crossbeam and a longitudinal beam connected to one end of the crossbeam. The front and rear sides of the bottom end of the longitudinal beam are respectively connected to fixed-end traveling wheels via inverted U-shaped brackets I.

[0006] A further technical solution of the present invention is as follows: the push-pull mechanism includes a push-pull handle, a push-pull shaft, and a push-pull rod. The push-pull handle is located on the upper surface of the crossbeam, and one end of the push-pull handle is connected to the push-pull shaft. The middle part of the push-pull rod is located on the upper surface of the crossbeam, and both ends of the push-pull rod extend downward and are respectively connected to the sliders on both sides of the crossbeam. The middle part of the push-pull rod is provided with a positioning hole that cooperates with the push-pull shaft. The push-pull shaft passes through the positioning hole at the end away from the push-pull handle, and the end of the push-pull shaft away from the push-pull handle is provided with a boss. By pushing or pulling the push-pull handle, the push-pull rod can push or pull the sliders on both sides of the crossbeam to move relative to the guide rail, thereby adjusting the position of the moving end traveling wheel and the moving end positioning wheel on the lower side of the slider.

[0007] A further technical solution of the present invention is: a top rod is provided on one side of the pivot seat on the upper surface of the crossbeam, the bottom end of the top rod is hinged to the upper surface of the crossbeam on one side of the pivot seat, the top end of the top rod is hinged to the vertical rod, and when the vertical rod is erected in the pivot seat, the top rod is supported between one side of the vertical rod and the upper surface of the crossbeam. The upper surface of the crossbeam is also provided with a limiting seat for supporting the end of the vertical rod when the vertical rod is folded in the pivot seat and parallel to the upper surface of the crossbeam.

[0008] A further technical solution of the present invention is: the inner wall surface of the inverted U-shaped bracket I is connected with two vertically downward extending connecting rods at intervals, and the bottom end of each connecting rod is connected to a fixed end positioning wheel for positioning on the inner wall of the rail.

[0009] A further technical solution of the present invention is as follows: the bottom end of the connecting plate to which the two sliders are connected is vertically connected to a mounting plate, and two inverted U-shaped brackets II are connected to the bottom surfaces of the front and rear ends of the mounting plate.

[0012] A further technical solution of the present invention is that a battery pack is also provided on the upper surface of the crossbeam.

[0013] The high-speed rail platform train passage safety control parameter detection system of the present invention has the following beneficial effects: 1. This invention, by setting a fixed-end positioning wheel inside the fixed-end traveling wheel and a movable-end positioning wheel and a movable-end measuring wheel inside the movable-end traveling wheel, can quickly detect the track gauge. The platform clearance measurement sensor connected to the vertical rod can quickly measure the distance from a point on the side facade of the high-speed railway platform to the perpendicular bisector of the rail surface, and the distance from a point on the edge of the platform top surface to the rail surface. The canopy clearance mounting base is equipped with a canopy and tunnel clearance measurement device, which can directly measure the canopy and tunnel clearance dimensions. The measurement parameters can be transmitted to a computer in real time via Bluetooth, realizing multi-parameter integrated synchronous detection. This solves the defects of traditional equipment, such as step-by-step detection, low efficiency, and poor data correlation, and improves detection efficiency and data accuracy.

[0014] 2. In this invention, the platform clearance measurement sensor on the vertical pole can be installed at different positions on the vertical pole. In conjunction with the guide rail sliders set on both sides of the crossbeam of the movable measuring end, the movable end traveling wheel, movable end positioning wheel, and movable end measuring wheel of the movable measuring end can move together with the slider relative to the guide rail as a whole, realizing rapid switching detection between high-speed rail high platforms and ordinary low platforms without the need to replace the sensor. The movable end positioning wheel and the tightening spring are designed to adapt to different track gauges, solving the problem of poor versatility of traditional equipment and reducing equipment investment.

[0015] 3. Because the vertical rod adopts a foldable structure, combined with the platform clearance measurement sensor and angle encoder, the present invention can achieve seamless switching between platform and tunnel scenarios; the vertical rod can be laid flat in the tunnel to complete the cross-section scanning, contour generation and distance calculation, solving the problems of large size and poor adaptability of traditional equipment, and improving the flexibility and accuracy of detection.

[0016] 4. Because the present invention has a walking drive mechanism on the outside of the longitudinal beam that can drive the fixed end walking wheel to rotate, the detection system can achieve automatic movement. The detection vehicle moves automatically and records the mileage without manual pushing. The control system of the tablet computer is set to set the alarm light to flash when the parameters exceed the limit and can accurately locate the over-limit position. Combined with the integrated operation of the tablet computer, the process is simplified, the threshold is lowered, and the intelligent upgrade of detection is realized.

[0017] 5. This invention uses line laser sensors to measure the clearance dimensions of platforms; spot laser sensors and angle encoders to measure the clearance dimensions of canopies and tunnels; electronic rulers to measure track gauge; and tilt sensors to measure superelevation. The data is digitally transmitted to a tablet computer. By digitally collecting the measurement data, traceability of operation and maintenance is achieved.

Based on the trolley's mileage, the corresponding out-of-tolerance location is also located, enabling rapid identification and handling of out-of-tolerance locations. Inside the tunnel, the vertical rod 11 can be laid flat. Clicking on "Tunnel Clearance Measurement" on the tablet computer causes a laser to rotate and scan around the tunnel cross-section, forming the tunnel cross-sectional profile. The distance from each point to the track center is calculated using the encoder angle.
