DETAILED DESCRIPTION

[0026] The present application will be further described below with reference to the drawings.

[0027] Railway safety is the fundamental prerequisite and foundation of high-speed railway transportation, and the pros and cons of the state and performance of the rail itself are directly related to the stability and safety of train operation. As one of the important components of track structure, the smoothness of the rail itself is very important for the maintenance of the line. The rail is in direct contact with the train wheel, and its state directly affects the safety and stability of the train. If the rail profile is poor, it will inevitably cause the mismatch of wheel-rail contact, intensify the snake movement of the vehicle, produce lateral acceleration alarm, and cause strong vibration and noise of the wheel-rail system. Effective control of the state of railway rail and corresponding effective maintenance and repair to improve the wheel-rail contact relationship have become the focus of railway maintenance work.

[0028] With the operation and development of China's railways, some diseases of the rail, such as rail welding joint irregularity, periodic irregularity of rail top surface, abnormal wheel-rail contact light strip, and abnormal wear of rail profile, have occurred and their development has become increasingly prominent. The consequences of such track conditions not only cause abnormal wheel-rail contact, increase of track additional dynamic load, damage of track and vehicle parts, and increase of track maintenance cost, but also significantly reduce the train operation quality, i.e. train operation stability and comfort index. In recent years, with the development of rail repair technology, rail grinding and milling have been introduced, digested, tested, and widely applied and become a routine maintenance. The measurement technology and evaluation technology of the required rail technical parameters have also followed the development. Rail profile detection has developed from manual point-type side grinding and vertical grinding detection to static rail profile electronic detector detection, rail straightness detection has developed from manual one-meter straight steel ruler detection to electronic rail straightness detector detection, and rail light strip measurement has developed from manual ruler measurement and manual visual method to automatic detection method based on machine vision, which provides help for the accuracy and depth of rail state analysis, but they all cannot meet the development needs of today's high-speed railways and have certain shortcomings and defects. The current domestic and foreign equipment for collecting and evaluating the state of the rail, whether single-function or multi-function superimposed instruments, cannot efficiently, quickly, and timely evaluate the detected line perfectly. There are a lot of collected data to be sorted out, slow speed of issuing evaluation and analysis report, and difficult cooperation with grinding operation, etc.

[0029] For a long time, China's railway adopts very simple manual detection tools for rail profile and rail wear detection, and most of them are detected by static contact or non-contact detection, which has low detection efficiency; some use non-contact handcart to detect rail quality state, but the function is relatively single, the detection efficiency is low, and only about 6km test line can be completed in a skylight, and the overall analysis and inspection of the rail quality state cannot be carried out; at present, it is loaded on a large track inspection vehicle, and the installation scheme is changed with the attitude of the vehicle, which leads to poor precision of the detection equipment and cannot effectively guide the rail grinding or post-grinding acceptance evaluation. Based on this, the embodiment of the present application provides a rail profile and wear detection device and system, which can at least solve the above technical problems.

[0030] Please refer to Figure 1 , a rail profile and wear detection device is provided, and the rail wear detection device 101 (hereinafter referred to as the detection device 101) comprises: a transverse moving assembly 1, a detection unit 2 and a longitudinal moving assembly 3, wherein the bottom of the transverse moving assembly 1 is used to be installed on the rail to be detected 100, and the transverse moving assembly 1 is configured to be movable along the first direction of the rail to be detected 100; the detection unit 2 is connected with the transverse moving assembly 1, and the detection surface of the detection unit 2 is opposite to the rail to be detected 100; the longitudinal moving assembly 3 is connected with the top of the transverse moving assembly 1, and the longitudinal moving assembly 3 is configured to be movable along the second direction of the rail to be detected 100, and the first direction is perpendicular to the second direction.

[0031] In a preferred embodiment, the detection unit 2 can adopt the existing profile and wear detection device 101, such as a rail profile (wear) measuring instrument.

[0032] Please refer to Figure 2 , in a preferred embodiment, the transverse moving assembly 1 comprises: a first connecting plate 11, a first sliding part and a first driving part; the top of the first connecting plate 11 is connected with the longitudinal moving assembly 3; the first sliding part is slidingly connected with the bottom surface of the first connecting plate 11; the first driving part is connected with the first sliding part, and the first driving part is used to drive the first sliding part to slide on the first connecting plate 11 along the first direction; the detection unit 2 is connected with the first sliding part.

[0033] The top of the first connecting plate 11 is provided with a connecting rod, and the connecting rod is connected with the longitudinal moving assembly 3; when the longitudinal moving assembly 3 connection moves along the first direction (the up-down direction when the detection device 101 is placed and used), since the longitudinal moving assembly 3 connection is connected with the transverse moving assembly 1 through the connecting rod and the first connecting plate 11, the transverse moving assembly 1 can be driven to move up and down.

[0034] In a preferred embodiment, the device provided by the embodiment of the present application further comprises a position sensor arranged on the longitudinal moving assembly 3 and the transverse moving assembly 1. Further, the position sensor is arranged on the first sliding part of the transverse moving assembly 1. By acquiring the position information of the first sliding part, the movement of the first sliding part is controlled, the efficiency of the position adjustment of the detection unit 2 is improved, and the detection accuracy is further improved.

[0035] In a preferred embodiment, the device provided by the embodiment of the present application further comprises a stop sensor 8 arranged on one side of the detection unit 2. The stop sensor 8 can prevent the excessive movement of the detection unit 2 and cause damage to the detection unit 2.

[0036] In a preferred embodiment, the first sliding part comprises a slide rail 12 and a slide block 13. The slide rail 12 is arranged on the bottom surface of the first connecting plate 11, and the slide block 13 is in sliding connection with the slide rail 12. The first driving part is connected with the slide block 13, and the detection unit 2 is connected with the slide block 13.

[0037] The number of slide rails 12 can be two, i.e., two slide rails 12 are arranged on the two sides of the bottom surface of the first connecting plate 11, respectively. The detection unit 2 is connected with the slide block 13, and when the slide block 13 moves along the second direction (the width direction of the steel rail 100 to be detected), the detection unit 2 is connected with the slide block 13. Therefore, the detection unit 2 moves together with the slide block 13, and the position between the detection unit 2 and the steel rail 100 to be detected is adjusted, so as to improve the detection accuracy.

[0038] In a preferred embodiment, the first driving part comprises a first stepping motor 14, a first screw rod, and a first push rod. The first stepping motor 14 is connected with the first screw rod, the first screw rod is connected with the first push rod, and the first push rod is connected with the first slide block 13.

[0039] The first stepping motor 14 generates a rotating power after being started, and the power is transmitted to the first push rod through the first screw rod (a transmission device). The first screw rod converts the rotating motion of the first stepping motor 14 into a linear motion, so as to realize the reciprocating motion of the first push rod. The reciprocating motion of the first push rod drives the reciprocating motion of the first slide block 13, and further realizes the reciprocating motion of the detection unit 2. The position and speed of the first push rod can be accurately controlled, and the position and speed of the detection unit 2 are further controlled, so as to improve the detection accuracy.

[0040] Please refer to Figure 3 In a preferred embodiment, the longitudinal moving assembly 3 comprises a second connecting plate 31, a second sliding part, and a second driving part. One end of the second sliding part is connected with the second connecting plate 31, and the other end is connected with the transverse moving assembly 1. One end of the second driving part is connected with the second connecting plate 31, and the other end is connected with the transverse moving assembly 1. The second driving part is used to drive the transverse moving assembly 1 to slide along the first direction.

[0041] It can be understood that when the second driving part directly drives the lateral moving assembly 1 to move along the first direction (up and down direction when the detection device 101 is used), the gravity of the lateral moving assembly 1 is all concentrated on the second driving part, which increases the burden of the second driving part and accelerates the damage of the second driving part. Therefore, the second sliding part is arranged in the embodiment of the application, one end of the second sliding part is connected with the second connecting plate 31, and the other end is connected with the lateral moving assembly 1, that is, a part of the gravity of the lateral moving assembly 1 is shared, and the second sliding part has the function of sliding along the second direction, that is, the lateral moving assembly 1 is driven to rise and fall along the first direction when the second driving part moves, so that the burden of the second driving part is reduced, and the service life of the detection device 101 is improved.

[0042] In a preferred embodiment, the second sliding part comprises at least two sliding assemblies, and each sliding assembly comprises a sliding sleeve 32 and a sliding rod 33; one end of the sliding sleeve 32 is connected with the second connecting plate 31, and the other end is slidably connected with the sliding rod 33; the sliding rod 33 is connected with the lateral moving assembly 1; and the two sliding assemblies are located on both sides of the second driving part.

[0043] The two sliding assemblies in the embodiment of the application are arranged on both sides of the second driving part, and the gravity of the lateral moving assembly 1 is evenly shared.

[0044] In a preferred embodiment, the second driving part comprises a second stepping motor 34, a second screw rod and a second push rod; the second stepping motor 34 is connected with the first screw rod, the second screw rod is connected with the second push rod; and the second push rod is connected with the lateral moving assembly 1.

[0045] The second stepping motor 34 generates rotary power after starting, and the power is transmitted to the second push rod through the second screw rod (transmission device). The second screw rod converts the rotary motion of the second stepping motor 34 into linear motion, so as to realize the reciprocating motion of the second push rod. The reciprocating motion of the second push rod drives the reciprocating motion (up and down direction when the detection device 101 is used) of the lateral moving assembly 1, and further realizes the reciprocating motion of the detection unit 2. The position and speed of the lateral moving assembly 1 can be accurately controlled, and the position and speed of the detection unit 2 can be further controlled, so as to improve the detection precision.

[0046] Please refer to Figure 4 In a preferred embodiment, the detection device 101 further comprises a lifting mechanism 4; the lifting mechanism 4 is rotatably connected with the longitudinal moving assembly 3, and the lifting of the lifting mechanism 4 drives the longitudinal moving assembly 3 to move along the second direction.

[0047] The lifting mechanism 4 provided by the embodiment of the present application can be manually rotated, and when the longitudinal moving assembly 3 fails, the lifting mechanism 4 can be rotated, and when the lifting mechanism 4 is lifted, the detection unit 2 connected with the transverse moving assembly 1 is also lifted, so that a distance for safe driving is reserved between the detection device 101 and the rail 100 to be detected.

The rotating part 42 can be a rotating ring in a circular shape, which is connected with the worm shaft 44. Since the rack on the worm shaft 44 is engaged with the rack on the worm wheel 43, and the worm wheel 43 is connected with the longitudinal moving assembly 3 through the worm wheel 43 axis, i.e. the worm wheel 43 is connected with the motor housing 5 of the second step motor 34 through the worm wheel 43 axis, when the longitudinal moving assembly 3 fails, the rotating part 42 can be manually rotated, and when the longitudinal moving assembly 3 is lifted, the transverse moving assembly 1 connected with the longitudinal moving assembly 3 is also lifted, and the detection unit 2 connected with the transverse moving assembly 1 is also lifted, so that a distance for safe driving is reserved between the detection device 101 and the rail 100 to be detected.
