Description

Technical Field

[0001] The invention belongs to the technical field of manned track inspection, and in particular relates to a portable manned track inspection device. Background Art

[0002] So far, the operating mileage of electrified railways in China has reached 141,400 kilometers, including 36,000 kilometers of high-speed railways. The safe operation of railways is inseparable from reliable bow-net relations, smooth tracks, and decades of repair and maintenance by railway workers. In order to solve the problems of workers walking long distances and carrying tools during maintenance, many small vehicles for carrying people and goods have been put into operation. In order to regularly and comprehensively understand the parameters of the track or contact network, large contact network operation vehicles and track inspection vehicles have emerged in an endless stream. Compared with large track inspection vehicles or contact network inspection vehicles, portable small inspection vehicles with the same functions have also been put into operation. All large or small vehicles are used in the same period, that is, the "window period". During the "window period", the large or small vehicles in working state do not have a unified working or non-working display status on the track. Common small inspection equipment does not have a unified track status display, resulting in a chaotic state and inconvenience in regularization; small vehicles with detection functions cannot carry people and goods, and people are prone to fatigue during long-distance follow-up inspections; large track inspection vehicles cannot inspect working areas such as multiple turnouts. Therefore, there is an urgent need for a manned multifunctional inspection vehicle that can display working or non-working status on track as an inspection device.

[0003] China's patented railway infrastructure detection system CN201910851582.7 discloses a railway infrastructure detection system, which includes: a positioning and synchronization subsystem, and a track geometry detection subsystem, a track profile detection subsystem, a track state detection subsystem, a wheel-rail detection subsystem, a contact network geometry parameter detection subsystem, and a pantograph current collection parameter detection subsystem that communicate with the positioning and synchronization subsystem.

[0004] However, in this solution, large inspection vehicles can only conduct regular inspections and lack mobility and real-time performance.

[0005] Chinese patent CN201921520705.0, a vehicle-mounted bow-net dynamic detection platform, discloses a vehicle-mounted bow-net dynamic detection platform, including a detection mounting platform, the detection mounting platform is a rectangular parallelepiped with a hollow middle part, the bottom step of the detection mounting platform is connected and fixed to the top of the car with punched bolts, and the detection mounting platform is provided with a number of threading elbow holes that pass through the top of the car; it also includes a geometric parameter measurement unit, a pantograph dynamic detection unit, a contact network suspension imaging unit, a bow-net infrared temperature measurement unit, a contact network wear detection unit, a wireless communication device, a trigger device, and a power control box that are fixed to the detection mounting platform by bolts. The above-mentioned equipment is connected to the control and processing system in the car by cables through the threading elbow holes.

[0006] However, the small and medium-sized inspection vehicles in this solution do not have the function of carrying people and goods, and do not display the on-road working status. Summary of the invention
