Description

Technical Field

[0001] This invention relates to the field of rail inspection technology, and in particular to a multi-machine cooperative monorail rail service condition inspection device. Background Technology

[0002] With the rapid development of railways, the weight of trains and the density of traffic are constantly increasing, and the working time and frequency of railway tracks are also increasing accordingly. Tracks that have been in service for a long time may suffer from varying degrees of damage, threatening traffic safety. In order to ensure that the tracks can be used normally and to guarantee railway safety, regular inspection and maintenance of the tracks are essential. The increase in railway operating lines and the increase in traffic density have placed higher demands on railway track inspection equipment and technology.

[0003] Currently, rail inspection is mainly carried out using vehicle-mounted inspection vehicles. While large track inspection vehicles are efficient and reliable, they are costly and place significant pressure on transportation and scheduling. Portable track inspection trolleys, on the other hand, are easy to operate and have lower costs, providing strong support for large track inspection vehicles and making them easier to adopt in railway track inspection.

[0004] The monorail inspection method is a new type of inspection device proposed by researchers in recent years. Compared with the traditional dual-rail inspection trolley, the monorail inspection trolley is smaller, lighter, and more portable. Under the condition of similar inspection performance, the monorail inspection trolley can better adapt to inspection sections that need to be changed frequently, and has higher work efficiency.

[0005] Currently, there is no existing technology that can efficiently and conveniently detect the condition of rails using a monorail inspection-type online rail condition monitoring trolley. Summary of the Invention

[0030] To facilitate understanding of the embodiments of the present invention, the following will provide further explanation and description with reference to the accompanying drawings and several specific embodiments. These embodiments do not constitute a limitation on the embodiments of the present invention.

[0031] This invention provides a multi-machine cooperative monorail rail service condition detection device. The device adopts a modular design, featuring a simple structure, small size, light weight, and easy assembly and maintenance. After simple installation, it can stably stop and run on the monorail. Simultaneously, the device has a certain degree of flexible adjustment capability, enabling it to adapt to complex conditions such as curved tracks. This device not only achieves online detection of rail service condition but also effectively controls the size and weight of the track assembly.

[0032] A structural diagram of a multi-machine cooperative monorail rail service status device provided in this embodiment of the invention is shown below. Figure 1a , Figure 1b and Figure 1c As shown, it includes a drive wheel system, a support wheel system, a housing structure, a limiting structure, an electrical mounting plate, and an installation and disassembly structure.

[0033] The support wheel system includes front and rear support wheels 15, front and rear support wheel axles 16, bearings, couplings 17, and encoders 18, as well as a housing structure for fixing the various devices. The support wheel system does not have a power system; it only performs mileage measurement and load-bearing. The front and rear support wheel axles 16 are connected to the encoders 18 via couplings 17 for mileage measurement.

[0034] The housing structure includes an outer shell structure 5, a fixed plate 4, a movable plate 2, and a sensor mounting bracket 3. The movable plate 2 is connected to the drive wheel system and the limiting mechanism by bolts. The fixed plate 4 is connected to the drive wheel system, the limiting mechanism, the encoder 17, and the motor bracket 25 by bolts.

[0035] The outer casing structure 5 includes a front plate, a rear plate, and two side support plates. The front plate of the outer casing structure 5 is connected to the sensor mounting bracket 3 by bolts, and an infrared ranging device can be installed on the sensor mounting bracket 3.

[0036] The drive wheel system includes a drive motor 26, a winding coupling 24, a tapered rubber wheel 22, bearings, a drive wheel shaft 23, a driven wheel shaft 20, and a drive wheel frame 21, a driven wheel frame 19, a motor bracket 25, and a housing structure that support the above-mentioned devices.

[0037] In the drive wheel system, the left rear conical rubber wheel is fixed to the movable plate 2 of the housing via drive wheel shaft 23, bearings, and drive wheel frame 21. Drive wheel shaft 23 is connected to drive motor 26 via winding coupling 24 to transmit power. Drive motor 26 is fixed to the housing mounting plate via motor bracket 25. The remaining conical rubber wheels are fixed to the housing via driven wheel shaft 20, bearings, and driven wheel frame 19. After the device is installed, the conical rubber wheel 22 is in close contact with the rail head and drives the device to operate under the action of drive motor 26.

[0038] The limiting mechanism comprises a limiting wheel 27, a limiting wheel axle 28, a needle roller bearing, a fixed frame 29 supporting the device, and a housing structure. The limiting wheel axle 28 is fixed to the fixed frame 29 by bolts, and the limiting wheel 27 and the needle roller bearing are sequentially installed on the limiting wheel axle 28. The limiting wheel 27 is shaped to conform to the bottom surface of the rail head and has a certain gap, so it will not affect the normal movement of the device and prevent the device from tipping over.

[0039] The electrical mounting plate 9 is fixedly connected to the top of the housing support plate. Infrared ranging devices 11 are mounted on the electrical mounting plate 9 in four directions (front, back, left, and right) via bolts and ranging brackets 10. A detection camera 6 is connected to the front end of the electrical mounting plate 9 via a lens mounting base 8 and a lens movable base 7. The electrical mounting plate 9 has internal space for mounting sensors such as distance sensors, positioning systems, and gyroscopes.

[0040] The installation and disassembly structure includes positioning posts 14, limiting posts 13, flat fasteners 12, and a housing structure supporting the aforementioned device. One side of the drive wheel system and the limiting wheel system is fixedly connected to the movable plate 2. Similarly, four positioning posts 14 are also located on one side of the movable plate 2, used to position the movable plate 2 relative to the housing shell 5 during installation. Three limiting posts 13 are fixedly connected to the housing shell 5. After initial positioning, a portion of the limiting posts 13 will protrude from the movable plate. Fastening the flat fasteners 12 restricts the movement of the movable plate. The flat fasteners 12 are connected by springs, thus completing the installation of the trolley on the rails. During disassembly, removing the flat fasteners 12 from the movable plate disassembles the entire device, facilitating the installation and separation of the platform from the rails.

[0041] Figure 2 This is a schematic diagram illustrating a collaborative measurement implementation method for a multi-machine cooperative monorail rail service status detection device provided in this invention. The multi-machine cooperative process of this device includes: the device detects the rail spacing using a distance sensor; the device can also be equipped with sensors such as a positioning system and a gyroscope to identify the rail's geographical location and track deformation; the device can perform online or offline detection of the rail surface condition using a detection camera 6 and an infrared ranging device 11 to identify surface defects; then, it uses an encoder 17 and a positioning system to achieve positioning and mileage recording; upon receiving fault information from the detection system, it records the location information of the fault point. Information such as rail service status, mileage, and fault point location can be transmitted to the user terminal in real time via radio, realizing online detection of the rail service status.

[0042] In the multi-machine collaboration process of the above-mentioned devices, a wireless networking method is used to realize the linkage between multiple devices. Each device can measure different rail data and integrate the data to a PC through wireless networking, thereby realizing multi-machine collaboration.

[0043] In summary, the multi-machine cooperative monorail rail service condition detection device of the present invention has the following beneficial effects:

[0044] (1) It adopts a single-rail drive self-propelled mode, which has high detection efficiency, simple structure, reasonable space allocation, and small size, making it easy to transport and carry.
