Description

Technical Field

[0001] This utility model relates to the field of railway testing technology, specifically to a novel air testing robot. Background Technology

[0002] With the development of railway transportation, the requirements for the length, weight, and load capacity of traction trains are constantly increasing, and train speeds are also continuously rising. Braking safety is the prerequisite and foundation for safe train operation, and the train inspection brake air test is directly related to train operation safety. The main purpose of conducting an automatic brake test on a train is to inspect the entire braking system. Before a train departs, or when a train stops at an intermediate station for more than twenty minutes, a train air test is required to confirm that the entire air duct is unobstructed and the braking system is functioning properly.

[0003] Currently, train inspection and air release tests mainly rely on manual labor. This manual work requires traversing tracks or crawling under the train to visually inspect whether the braking components are functioning properly during the air release test, which is prone to personal injury accidents and poses a safety hazard. Furthermore, the risk of missed inspections is also influenced by the individual's sense of responsibility and physical condition. Utility Model Content

[0004] The first aspect of this utility model aims to solve the technical problems of safety hazards and missed detections in the existing technology of conducting train air testing by manual operation, and provides a novel air testing robot that is installed at the bottom of the train and performs moving detection with the help of auxiliary tracks. The main concept is as follows:

[0005] A novel air-testing robot includes an air-testing track and a traveling mechanism that slides along the track. The air-testing track is installed parallel to the middle of the railway. The traveling mechanism includes a guide car and a detection component housed inside the guide car. The detection component is used to identify the condition of the train's underside. This solution sets the air-testing track in the middle of the railway, allowing the traveling mechanism to slide along it. The detection component, which monitors and detects the train's underside braking equipment, is mounted on the guide car of the traveling mechanism. By driving the guide car, the detection component can perform comprehensive inspections along the train's underside. The air-testing robot can operate inside the railway, avoiding interference and obstruction caused by the train's structure, obstacles on both sides of the track, and inclement weather. This ensures clear, efficient, and accurate acquisition of the working status of each component, improving inspection efficiency and avoiding the safety risks associated with manual inspection.

[0006] Preferably, the test track has an I-shaped structure, comprising an upper leg, a lower leg, and a waist section, with the upper and lower legs connected by the vertically arranged waist section. Choosing an I-shaped track provides high strength and rigidity, reduces material usage, and offers strong resistance to bending and torsion, making it less prone to deformation. This improves the load-bearing capacity of the test track and increases the stability of the ride.

[0007] The second aspect of this utility model aims to solve the technical problem that a guided vehicle is prone to derailment due to vibration or impact during operation. Further, the guided vehicle includes rollers and auxiliary wheels. The rollers abut against the upper leg of the test track. The auxiliary wheel is positioned at the waist of the test track via a bending member, and the upper leg is located above the auxiliary wheel. By adding an auxiliary wheel at the waist of the test track through a bending member at the engagement position of the guided vehicle and the test track, and by constraining the vertical upward movement of the auxiliary wheel through the upper leg, the guided vehicle runs on the test track via the rollers. When the guided vehicle tends to deviate upwards due to vibration or other reasons, the action of the auxiliary wheel and the waist of the test track prevents derailment. Furthermore, the auxiliary wheel is connected to the bending member via a pivot, allowing the auxiliary wheel to roll against the bottom of the upper leg, preventing jamming during auxiliary wheel positioning and improving the stability of the guided vehicle's operation.

[0008] Preferably, the test track is installed in the middle of the railway via a track mounting structure. The track mounting structure includes a fastening mechanism and a positioning mechanism. Two positioning mechanisms are symmetrically arranged above the fastening mechanism. The fastening mechanism is connected to a sleeper in the middle of the railway, and the positioning mechanisms are used to position and install the test track. This design places the structure for installing the test track on a sleeper in the middle of the railway. Compared to placing it on the ballast bed in the middle of the railway, the sleeper has better stability and support strength, resulting in a better installation effect for the test track.

[0009] The third objective of this invention is to address the technical problem that an excessively high placement of the air-testing robot beneath a train could interfere with its normal operation. Further, the fastening mechanism includes an upper pressure plate, a lower pressure plate, and threaded connecting rods. The upper and lower pressure plates are fastened together around their perimeter by the threaded connecting rods. The upper pressure plate has multiple mounting holes for installing a positioning mechanism. This solution places the fastening mechanism on the railway sleeper. By tightening the threaded connecting rods, the upper and lower pressure plates are wrapped around the sleeper, eliminating the need for drilling or mechanical deformation of the sleeper. This does not affect the strength of the railway structure or the sleeper. Furthermore, by pressing the threaded connecting rods against the four corners of the upper and lower pressure plates, a central mounting position is provided for the positioning mechanism above the fastening mechanism. This controls the overall installation height of the track installation structure, preventing the air-testing robot from interfering with train operation due to excessive height.

[0010] Preferably, the positioning mechanism includes positioning plates, and the adjustable base has a positioning groove for accommodating and positioning the test air track. Positioning plates are provided on both sides of the positioning groove. The positioning plates on both sides of the positioning groove press the lower part of the test air track firmly.

[0011] The fourth aspect of this utility model aims to solve the technical problem that the positioning mechanism cannot be adaptively adjusted. Preferably, the adjustable base has a first strip-shaped hole and a pressure plate connecting hole. The adjustable base is connected to the mounting hole of the upper pressure plate by bolts. The installation position of the adjustable base is adjusted through the first strip-shaped hole and the bolts. The positioning pressure plate has a second strip-shaped hole. The positioning pressure plate is connected to the pressure plate connecting hole of the adjustable base through the second strip-shaped hole. The installation position of the positioning pressure plate is adjusted through the second strip-shaped hole and the bolts. This solution, by setting the first strip-shaped hole and the second adjustment hole, allows the adjustable base and the positioning pressure plate to be adaptively adjusted in two directions above the fastening mechanism. The position of the adjustable base on the fastening mechanism is adjusted through the first strip-shaped hole, so that the positioning groove of the adjustable base accurately accommodates the test air track. Then, the positioning pressure plates on both sides of the positioning groove are adjusted through the second strip-shaped hole, so that the positioning pressure plates are pressed tightly against the lower part of the adjustable track along the bottom surface of the adjustable base. Through adaptive adjustment, it can adapt to the installation of different models of test air tracks.

[0012] Preferably, the detection component includes an image recognition module, a vehicle number recognition module, and a communication module. The image recognition module is used to acquire images of key structures of the train, the vehicle number recognition module is used to locate the rear of the train, and the communication module is used to send information from the image recognition module to the central control console.

[0013] The beneficial effects of this utility model are as follows:

[0014] This solution involves setting up a test track in the middle of the railway, allowing a traveling mechanism to slide along it. A detection component capable of monitoring and inspecting the train's undercarriage braking equipment is mounted on a guide vehicle of this traveling mechanism. Driving the guide vehicle enables the detection component to perform comprehensive inspections along the train's undercarriage. The test robot can operate on the inside of the railway, avoiding interference or obstruction caused by the train's structure, obstacles on both sides of the track, and adverse weather conditions. This ensures clear, efficient, and accurate acquisition of the working status of each component, improving inspection efficiency and avoiding the safety risks associated with manual inspection.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0022] It should be noted that all actions involving the acquisition of signals, information, or data in this application are carried out in compliance with the relevant local data protection regulations and with authorization from the owner of the relevant device.

[0023] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not imply sequence or importance.

[0024] Example 1:

[0025] like Figures 1-3 As shown, this embodiment provides a novel air testing robot, including an air testing track 1 and a walking mechanism 2 that slides along the air testing track 1. The air testing track 1 is installed parallel to the middle position of the railway. The walking mechanism 2 includes a guide car 21 and a detection component 3 disposed inside the guide car 21. The detection component 3 is used to identify the state of the bottom of the train from the top.

[0026] The test track 1 is installed in the middle of the railway, allowing the installation of a traveling mechanism 2 that can slide along the test track 1. The detection component 3, which can monitor and detect the braking equipment at the bottom of the train, is set on the guide car 21 of the traveling mechanism 2. By driving the guide car 21, the detection component 22 can perform a comprehensive inspection along the bottom of the train. The test robot can operate on the inside of the railway, avoiding the adverse effects of interference and obstruction caused by factors such as the train's own structure, obstacles on both sides of the track, and bad weather on the video acquisition of the test operation. This ensures that the working status of each component can be clearly, efficiently, and accurately collected, improving the efficiency of the inspection and avoiding the safety risks caused by manual inspection.

[0027] Preferably, the detection component 3 includes an image recognition module, a vehicle number recognition module, and a communication module. The image recognition module is used to acquire images of key structures of the train, the vehicle number recognition module is used to locate the rear of the train, and the communication module is used to send information from the image recognition module to the central control console.

[0028] After the test robot is activated, the walking mechanism 2 travels on the test track 1. Using the image recognition module of the detection component 3 mounted on the guide vehicle 21, it scans upwards until it reaches the rear of the train, then reverses direction. The vehicle number recognition module reads the vehicle number of the last car, and a 3D camera scans and inspects the ductwork and brake chain status. Furthermore, the 3D camera collects the outline data of the ductwork and air cylinders, and the lidar collects the distance data between the robot and key structures of the train, enabling precise positioning of the guide vehicle 21 on the test track 1.

[0029] Finally, after the test air robot stops below the cylinder brake lever, it sends a braking command to the driver. When the driver brakes, the equipment takes a video of the brake lever to confirm the test results. After the operation is completed, the test air robot automatically generates a test air operation report and uploads it to the station server using the communication module.

[0030] Example 2:

[0031] As in body 1- Figure 3 As shown, the test track 1 in this embodiment has an I-shaped structure. The test track 1 includes an upper leg 11, a lower leg 12, and a waist section 13. The upper leg 11 and the lower leg 12 are connected by the vertically arranged waist section 13. Choosing an I-shaped track for the test track 1 is advantageous because the I-shape offers high strength and rigidity, reduces material usage, and has strong resistance to bending and torsion, making it less prone to deformation. This improves the load-bearing capacity of the test track 1 and increases the stability of the ride.

[0032] The guide vehicle 21 includes rollers 211 and auxiliary wheels 212. The guide vehicle 21 abuts against the upper leg 11 of the test air track 1 through the rollers 211. The auxiliary wheels 212 are set in the waist 13 of the test air track 1 through bending parts 213. The upper leg 11 is located above the auxiliary wheels 212.

[0033] By adding an auxiliary wheel 212 to the waist 13 of the test track 1 through a bending member 213 at the matching position of the guide car 21 and the test track 2, and by constraining the vertical upward movement direction of the auxiliary wheel 212 through the upper leg 11, the guide car 21 runs on the test track 1 through the roller 211. When the guide car 21 tends to deviate upward due to vibration or other reasons, the auxiliary wheel 212 and the waist 13 of the test track 1 can prevent the guide car 21 from derailing. Furthermore, the auxiliary wheel 212 and the bending member 213 are connected by a pivot, which also allows the auxiliary wheel 212 to roll in contact with the bottom end of the upper leg 11, which can prevent jamming when the auxiliary wheel 212 is positioned, thus improving the stability of the guide car 21.

[0034] In this embodiment, the guide vehicle 21 is an AGV (Automated Guided Vehicle). The AGV is equipped with a vehicle controller, a motor driver, a battery, etc. The vehicle controller receives information from the navigation system and the sensor system, controls the motor driver to realize the movement of the vehicle, and the battery provides power to the AGV.

[0035] Example 3:

[0036] like Figures 4-5As shown, in this embodiment, the test track 1 is installed in the middle of the railway via a track mounting structure 4. The track mounting structure 4 includes a fastening mechanism 41 and a positioning mechanism 42. Two positioning mechanisms 42 are symmetrically arranged above the fastening mechanism 41. The fastening mechanism 41 is connected to the sleeper in the middle of the railway, and the positioning mechanism 42 is used to position and install the test track 1. This solution places the structure for installing the test track 1 on the sleeper in the middle of the railway. Compared to placing it on the ballast bed in the middle of the railway, the sleeper has better stability and support strength, resulting in a better installation effect for the test track 1.

[0037] The fastening mechanism 41 includes an upper pressure plate 411, a lower pressure plate 412, and a threaded connecting rod 413. The upper pressure plate 411 and the lower pressure plate 412 are fastened together around their perimeter by the threaded connecting rod 413. The upper pressure plate 411 has multiple mounting holes for mounting the positioning mechanism 42. In this design, the fastening mechanism 41 is installed on the railway sleeper. By tightening the threaded connecting rod 413, the upper pressure plate 411 and the lower pressure plate 412 are covered over the sleeper. The fastening mechanism 41 can be installed on the sleeper without drilling or mechanical deformation, and it will not affect the strength of the railway body or the sleeper. Furthermore, by pressing the four corners of the upper pressure plate 411 and the lower pressure plate 412 with the threaded connecting rod 413, a middle mounting position is reserved for the installation of the positioning mechanism 42 above the fastening mechanism 41. This controls the overall installation height of the track installation structure 4 and prevents the test robot from interfering with train operation due to excessive height.

[0038] In this embodiment, the bottom of the threaded connecting rod 413 is fixedly connected to the lower pressure plate 412. The threaded connecting rod 413 is fixed around the lower pressure plate 412. Positioning holes are opened around the upper pressure plate 411. The positioning holes are coaxially arranged with the threaded connecting rod 413. The upper pressure plate 411 and the lower pressure plate 412 are placed on the upper and lower positions of the railway sleeper, respectively. The threaded connecting rod 413 is inserted into the positioning holes and aligned. The tightening nut is placed on the threaded part above the threaded connecting rod 413 above the upper pressure plate 411. The nut is rotated and tightened so that the upper pressure plate 411 is pressed against the sleeper.

[0039] To prevent the nut from coming loose during use, a double-ended nut is used for tightening.

[0040] The positioning mechanism 42 includes an adjustable base 421 and a positioning plate 422. The adjustable base 421 has a positioning groove 425, which is used to accommodate and position the test air track 1. Positioning plates 422 are provided on both sides of the positioning groove 425. The positioning plates 422 on both sides of the positioning groove 425 are used to press the lower part 12 of the test air track 1 firmly.

[0041] The test air robot integrates the detection component 3 onto the guide vehicle 21, and the overall height of the test air robot's national highway installation structure 4 is compressed through reasonable layout. The overall structure of the test air robot is flat, compact, and ultra-thin. Including the height of the test air track 1 required for operation, the overall height does not exceed 25 mm above the track surface, so it will not affect the train's operation.

[0042] like Figure 5 As shown, the adjustable base 421 has a first strip-shaped hole 423 and a pressure plate connecting hole. The adjustable base 421 is connected to the mounting hole of the upper pressure plate 411 by bolts. The installation position of the adjustable base 421 is adjusted by bolts through the first strip-shaped hole 423. The positioning pressure plate 422 has a second strip-shaped hole 424. The positioning pressure plate 422 is connected to the pressure plate connecting hole of the adjustable base 421 by the second strip-shaped hole 424. The installation position of the positioning pressure plate 422 is adjusted by bolts through the second strip-shaped hole 424.

[0043] This solution allows the adjustable base 421 and positioning plate 422 to be adaptively adjusted in two directions above the fastening mechanism 41 by setting a first strip hole 423 and a second adjustment hole 424. The position of the adjustable base 421 on the fastening mechanism 41 is adjusted by the first strip hole 423 so that the positioning groove 425 of the adjustable base 421 accurately accommodates the test air track 1. Then, the positioning plates 422 on both sides of the positioning groove 425 are adjusted by the second strip hole 424 so that the positioning plates 422 are pressed against the lower foot 12 of the adjustable track 1 along the bottom surface of the adjustable base 421. Through adaptive adjustment, it can adapt to the installation of different models of test air tracks.

[0044] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
