[0024] See Figures 1 to 2 , an embodiment of the present invention provides a track detection beam, comprising a device installation beam 1, both ends of the device installation beam 1 are constructed with a quick installation structure;

[0025] The quick installation structure includes a quick adjustment joint 2, one end of the quick adjustment joint 2 is fixedly connected to the end of the device mounting beam 1, and the other end of the quick adjustment joint 2 is fixedly connected to the mounting seat 3, and the device mounting beam 1 is installed with a detection device. This technical solution connects the device mounting beam through the quick adjustment joint 2, which can be quickly disassembled from the quick adjustment joint 2, and can be easily disassembled and carried, solving the problem of being affected by the installation space under the vehicle bottom of different operating vehicles and having to redesign and process the track detection beam each time. The installation position and size of the track detection beam can be adjusted according to the actual installation space through the quick adjustment joint 2, which can adapt to the installation environment under the vehicle bottom of different vehicles. It can be quickly disassembled from the quick adjustment joint 2, which is easy to disassemble and carry, thereby improving the reuse rate of the track detection device and facilitating the later maintenance and disassembly of the various sensors of the track detection device. The device mounting beam 1 can be separated from the mounting seat 3 by the quick adjustment joint 2, so that the device mounting beam 1 can be moved out of the quick adjustment installation detection equipment.

[0026] In some embodiments, the quick adjustment joint 2 includes an outer sleeve 21 and a first screw, and inner plugs 22 are provided at both ends of the outer sleeve 21. The inner plugs 22 are respectively inserted into a port of the outer sleeve 21, and the inner plugs 22 at both ends of the outer sleeve 21 are respectively fixedly connected to the mounting seat 3 and the end of the device mounting beam 1. A plurality of first threaded holes 23 are provided on the inner plug 22 along the direction of insertion into the outer sleeve 21, and sockets 24 that cooperate with the first threaded holes 23 are provided on the side walls at both ends of the outer sleeve 21. The first screw is screwed into the first threaded hole 23 from the socket 24 to fix the inner plug 22. The quick adjustment joint 2 is matched by inserting the inner plug 22 into the outer sleeve 21, which is easy to dock when installing the device mounting beam 1, and the position of the device mounting beam 1 can be easily adjusted by simply adjusting the insertion depth of the inner plug 22 and selecting the corresponding first threaded hole 23.

[0027] In some embodiments, the outer sleeve 21 has two tube sections, each of which is mated with an inner plug 22. The two tube sections are fixedly connected at one end and are arranged vertically. When in use, the mounting base 3 is fixed to the bottom of the vehicle's compartment. The two tube sections of the outer sleeve 21 are arranged vertically. During installation, one section is connected to the mounting base 3, while the other section faces downward. This allows installation of the device mounting beam 1 by simply lifting it upward and pointing the inner plugs 22 at both ends of the device mounting beam 1 upward. Alignment only requires moving the outer sleeve 21, eliminating the need to move the heavy device mounting beam 1. Furthermore, the device mounting beam 1 is easy to disassemble; after loosening the first screw, the device mounting beam 1 falls under the influence of gravity.

[0028] In some embodiments, the insertion hole 24 is a bar-shaped hole, and the insertion hole 24 is parallel to the insertion direction of the inner plug 22 that matches the end of the outer sleeve 21. The bar-shaped insertion hole 24 provides greater flexibility for adjusting the position of the device mounting beam 1.

[0029] In some embodiments, the outer sleeve 21 is further provided with a reinforcing rib 25 , which is fixed at the connection between the two sections of the outer sleeve 21 , and both sections of the outer sleeve 21 are fixedly connected to the reinforcing rib 25 . The reinforcing rib 25 strengthens the strength of the outer sleeve 21 .

[0030] In some embodiments, the device mounting beam 1 is provided with a first quick-fixing structure, comprising a clamp 4 and a second screw. The clamp 4 has an opening, and first fixing holes 41 are provided at the ends of the clamp 4 on both sides of the opening. The device mounting beam 1 is provided with a second threaded hole that cooperates with the first fixing hole 41. The second screw is screwed from the first fixing hole 41 into the second threaded hole to fix the clamp 4 to the device mounting beam 1, so that the clamp 4 fixes the detection device to the device mounting beam 1. A method for installing and fixing the detection device on the device mounting beam 1 is provided, wherein the clamp 4 is used to hold the detection device on the device mounting beam 1, and the clamp 4 is fixed to the device mounting beam 1 by screws, which facilitates installation and disassembly.

[0031] In some embodiments, a second quick fixing structure is provided on the device mounting beam 1, and the second quick fixing structure includes a fixing plate 5 and a third screw. A second fixing hole is provided on the fixing plate 5, and a third threaded hole matching the second fixing hole is provided on the device mounting beam 1. The third screw is screwed from the second fixing hole into the third threaded hole to fix the fixing plate 5 to the device mounting beam 1. The fixing plate 5 is fixedly connected with a mounting plate 6 at an angle, and the detection device is fixed on the mounting plate 6. A method for installing and fixing the detection device on the device mounting beam 1 is provided. The tilted fixed mounting plate 6 is suitable for installing directional detection equipment, such as lasers, cameras and other track detection equipment. When in use, the fixing plate 5 is fixed to the bottom of the device mounting beam 1 so that the detection device points to the detection track.

[0032] In some embodiments, the device mounting beam 1 is provided with a third quick-fixing structure, which is a slot 7. The slot 7 is fixed to the device mounting beam 1 and cooperates with the detection device to clamp the detection device within the slot 7. This provides a method for mounting and fixing the detection device on the device mounting beam 1. The slot 7 engages with the detection device, making installation and removal simple and easy.

[0033] During use, the inertial package assembly, acceleration sensor assembly, laser, and camera assembly structure located in the detection beam of the prior art are respectively installed on the device mounting beam 1 through the first quick fixing structure, the second quick fixing structure, and the third quick fixing structure. The inertial package assembly, acceleration sensor assembly, laser, and camera assembly structure are placed outside the device mounting beam 1 to facilitate the subsequent maintenance and disassembly of the corresponding components.

[0034] In existing technology, the inertial package assembly primarily consists of a built-in battery, a data acquisition card, a gyro sensor, an inclination sensor, and a track orientation sensor. Its primary functions are to power the detection device, collect sensor data, and transmit the resulting data over the network. The data acquisition card utilizes Altai's PCI8622 acquisition module to collect and condition the analog signals from all sensors. The inclinometer and gyroscope measure the high- and low-frequency angles of the track inspection beam relative to the earth, respectively, establishing an inertial reference. This allows the angle of the rail plane relative to the earth to be calculated, thereby enabling the calculation of horizontal and superelevation values. The inertial package assembly is fixed to the device mounting beam 1 via a first fast-fixing structure.

[0035] The lateral acceleration sensor on the mounting beam 1 measures the beam's lateral acceleration. The lateral displacement of the mounting beam 1 relative to the track centerline is calculated through double integration. The left and right 2D measurements measure the horizontal displacement of the mounting beam 1 relative to the track. Combined with the inertial package data for attitude compensation, the track direction data can be inferred. The accelerometer assembly tooling, comprised of quartz servo accelerometers, measures the displacement of the left and right track inspection beams relative to the earth through double integration. Combined with the left and right 2D distances from the rail top and the track inspection beam attitude compensation, the left and right height values ​​can be calculated. The accelerometer is fixed to the mounting beam 1 via a third fastener.

[0036] The laser and camera assembly uses non-contact measurement to monitor the left and right rails in real time, capturing characteristic points 16 mm from the top of the rail to determine the rail's real-time status. Utilizing the principle of laser triangulation, a 2D laser sensor scans the rail surface, inner rail waist, and rail base. High-speed image processing technology extracts and analyzes the contour curve. Combined with the distance between the left and right 2D laser sensors, a dynamic track gauge value is calculated, resulting in the track gauge change rate. The laser and camera assembly is secured to the device's mounting beam 1 via a second fastener.

[0037] The quick adjustment joint 2 connecting device mounting beam can be quickly disassembled from the quick adjustment joint 2, which is convenient for disassembly and carrying. The quick adjustment joint 2 can be adjusted according to actual conditions, thereby improving the reuse rate of the track detection device and facilitating the later maintenance and disassembly of the sensors of the track detection device.

[0038] The above description is intended to be illustrative rather than restrictive, and those skilled in the art may make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present disclosure. Furthermore, the above examples (or one or more of them) may be used in combination with each other, and it is contemplated that these embodiments may be combined with each other in various combinations or permutations.
