[0055] The utility model concept of the utility model is further explained below in conjunction with some specific implementation methods.

[0056] The utility model provides a track monitoring device and a monitoring system.

[0057] like Figures 1 to 9 As shown, an embodiment of the track monitoring device and monitoring system of the present utility model is proposed.

[0058] See also Figures 1 to 8 , a track monitoring device, the track 10 includes a track bed 20 and two rails 30 spaced apart along the extension direction of the track 10, and an avoidance space 40 is formed between the two rails 30;

[0059] The track monitoring device includes a base 100, a driving mechanism 200, a detection mechanism 300 and a self-propelled mechanism 400. The base 100 is arranged in the avoidance space 40. A first installation position 110 is formed on the upper surface of the base 100, and a second installation position 120 is formed on the side of the base 100 away from the first installation position 110. The driving mechanism 200 is installed at the first installation position 110. The detection mechanism 300 is installed on the driving mechanism 200. The driving mechanism 200 can drive the detection mechanism 300 to extend out of the avoidance space 40 and detect each rail 30. The driving mechanism 200 can also drive the detection mechanism 300 to retract and be accommodated in the avoidance space 40 and make the top surface of the driving mechanism 200 and the detection mechanism 300 lower than the upper surface of the rail 30. The self-propelled mechanism 400 can be accommodated in the avoidance space 40 so that the top surface of the self-propelled mechanism 400 is lower than the upper surface of the rail 30. The self-propelled mechanism 400 includes a fixed component 410 and at least two self-propelled components 420. The fixed component 410 can extend out of the avoidance space 40 and be adsorbed and snap-connected with the upper surface of the bottom of at least one rail 30 away from the avoidance space 40, so as to fit the base 100 to the rail bed 20. At least two self-propelled components 420 are paired in pairs and are arranged on both sides of the base 100 facing the two rails 30. Each of the self-propelled components 420 can extend out of the avoidance space 40 and contact the rail 30 on the corresponding side to drive the base 100 to move along the track 10 when the fixed component 410 is detached from the rail 30.

[0060] In this embodiment, when in use, by setting the base 100, the driving mechanism 200, the detection mechanism 300 and the self-propelled mechanism 400, when in use, the base 100 is set in the avoidance space 40, so that the fixing component 410 can extend out of the avoidance space 40 and be adsorbed and snapped with the upper surface of the rail bottom of at least one rail 30 away from the avoidance space 40, so that the base 100 is attached to the rail bed 20, so that the driving mechanism 200 installed on the base 100 can drive the detection mechanism 300. The avoidance space 40 is extended relative to the base 100 and each rail 30 is inspected, so as to realize the function of automatically inspecting the rail 30; at the same time, the driving mechanism 200 can drive the inspection mechanism 300 to retract and be accommodated in the avoidance space 40, and the top surface of the driving mechanism 200 and the inspection mechanism 300 is lower than the upper surface of the rail 30, and the self-propelled mechanism 400 can be accommodated in the avoidance space 40, and the top surface of the self-propelled mechanism 400 is lower than the upper surface of the rail 30, so that the utility model The new type can avoid a train that is in operation and passing through the avoidance space 40 between the two rails 30; on this basis, the self-propelled component 420 is extended out of the avoidance space 40 and contacts the rail 30 on the corresponding side to drive the base 100 to move along the track 10 when the fixed component 410 is detached from the rail 30, so that the utility model can drive the base 100 and the driving mechanism 200 installed on the base 100 to move along the track 10 through the walking function of the self-propelled component 420, and there is no need for operators to drive or drive related equipment to walk on the track 10 when the track 10 traffic is not in operation, thereby avoiding manpower loss and improving the monitoring and detection efficiency. At the same time, since the track 10 monitoring device provided in the utility model has the self-propelled and avoidance functions, the utility model does not need to monitor and detect the track 10 in operation during the set skylight time when in use, thereby improving the monitoring and detection efficiency.

[0061] It should be particularly and clearly stated that the driving mechanism 200 exemplified in this embodiment may be, but is not limited to, a device or equipment that can drive the detection mechanism 300 to extend out of the avoidance space 40 and perform detection operations on the rail 30 on the corresponding side. Such a device or equipment may be a device or equipment that can be used in the prior art, or may be a device or equipment with driving and extension functions developed in the future. In this embodiment, the driving mechanism 200 exemplified is preferably a robotic arm with multiple flexible joints.

[0062] In some specific embodiments, the exemplary detection mechanism 300 should include an infrared detector 310 and an ultrasonic detector 320 , and the driving mechanism 200 can drive the infrared detector 310 and the ultrasonic detector 320 to extend out of the avoidance space 40 and detect each rail 30 respectively.

[0063] In this embodiment, the detection mechanism 300 is configured to include an infrared detector 310 and an ultrasonic detector 320, so that when the utility model is in use, the set driving mechanism 200 can be used to drive the infrared detector 310 and the ultrasonic detector 320 to extend out of the avoidance space 40 and detect each rail 30 respectively, so that when the utility model is in use, the set infrared detector 310 can be used to perform infrared detection on each rail 30 on the track 10 and the components (such as fasteners, etc.) matched with each rail 30 to determine whether they are loose or have defects. At the same time, the ultrasonic detector 320 of the dormitory is used to perform ultrasonic detection on the rail 30, so as to detect the structural state between the rail 30 and its components to determine whether there are defects such as wear or crack damage on the rail 30 and between the rail 30 and the corresponding components.

[0064] It should be particularly and clearly stated that in this embodiment, the exemplified infrared detector 310 and ultrasonic detector 320 preferably adopt existing devices or equipment in the prior art that can realize relevant detection functions. In this embodiment, they are only applied and their specific structures are not improved or designed, so they will not be described one by one here.

[0065] In some specific embodiments, the driving mechanism 200 includes two first robotic arms 210, which are installed at intervals at the first installation position 110, and both of the first robotic arms 210 can rotate relative to the base 100. An infrared detector 310 is installed at one end of one of the first robotic arms 210 away from the base 100, and can drive the infrared detector 310 to extend out of the avoidance space 40 and detect each rail 30; an ultrasonic detector 320 is installed at one end of the other first robotic arm 210 away from the base 100, and can drive the ultrasonic detector 320 to extend out of the avoidance space 40 and contact any rail 30 to detect the corresponding rail 30.

[0066] In this embodiment, two first robotic arms 210 are provided, and the infrared detector 310 and the ultrasonic detector 320 are respectively installed on one of the two robotic arms, so that when in use, the utility model can utilize the two provided robotic arms to respectively drive the infrared detector 310 and the ultrasonic detector 320 to extend out of the avoidance space 40, thereby realizing the functions of performing infrared detection operations and ultrasonic detection operations on the track 10 respectively, and improving the flexibility of the utility model.

[0067] It should be particularly and clearly stated that the first robotic arm 210 illustrated in the present embodiment is a robotic arm having at least three degrees of freedom, preferably a robotic arm having five degrees of freedom or seven degrees of freedom.

[0068] In some specific embodiments, the fixing component 410 includes a first telescopic member 411 and a snap-on assembly 412, the two ends of the first telescopic member 411 are respectively a first connecting end 211 and a first telescopic end 212, the first connecting end 211 is rotatably mounted at the second mounting position 120, the first telescopic end 212 can extend in the direction of the bottom of any rail 30, the snap-on assembly 412 is mounted at the first telescopic end 212, the first telescopic member 411 can drive the snap-on assembly 412 to extend along any gap between the same rail 30 and the rail bed 20 to below the bottom of the rail, so that the snap-on assembly 412 can be detachably snap-on to the bottom of the rail.

[0069] In this embodiment, by setting a first telescopic member 411 and a clamping assembly 412, the first telescopic member 411 is used to drive the clamping assembly 412 installed on its first telescopic end 212 to extend in the direction of the bottom of any rail 30, so that the clamping assembly 412 is extended to the bottom of the rail along any gap between the rail bed 20 and the same rail 30, and the clamping assembly 412 can be detachably clamped to the bottom of the rail, thereby realizing the function of connecting the base 100 with the rail 30, avoiding the shaking of the track 10 early warning monitoring device caused by the train when avoiding the track 10 passing through its position, and also avoiding the track 10 early warning detection device being carried away by the wind generated by the train, thereby improving the stability of the track 10 early warning monitoring device when it is housed in the track 10.

[0070] It should be particularly and clearly stated that the clamping assembly 412 includes a connecting plate 412a, a second telescopic member 412b and a first clamping block 412c, one end of the connecting plate 412a is connected to the first telescopic end 212, the second telescopic member 412b is installed on the side of the connecting plate 412a facing the sleeper, the second telescopic member 412b can drive the connecting plate 412a to rise until it contacts the lower surface of the rail bottom, the first clamping block 412c is installed on the end of the connecting plate 412a away from the first telescopic end 212, and the slot opening direction of the first clamping block 412c is set toward the direction of the upper surface of the rail bottom on the side of the rail 30 away from the avoidance space 40; the first telescopic member 411 can drive the connecting plate 412a to retract when the second telescopic member 412b drives the connecting plate 412a to contact the lower surface of the rail bottom, so that the first clamping block 412c is adsorbed and clamped to the upper surface of the rail bottom on the side of the rail bottom away from the avoidance space 40.

[0071] In this embodiment, the clamping assembly 412 is configured to include a connecting plate 412a, a second telescopic member 412b and a first clamping block 412c. When in use, the second telescopic member 412b drives the connecting plate 412a to rise to contact the lower surface of the rail bottom, and at the same time, the first telescopic member 411 can drive the connecting plate 412a to retract toward the base 100 when the second telescopic member 412b drives the connecting plate 412a to contact the lower surface of the rail bottom, so that the first clamping block 412c is adsorbed and clamped with the upper surface of the rail bottom away from the avoidance space 40 on the side of the rail bottom, so that the utility model can utilize the cooperation of the first clamping block 412c, the connecting plate 412a and the first telescopic member 411 to connect the base 100 with the rail bottom of the rail 30 when in use, thereby improving the stability of the track 10 early warning monitoring device when it is accommodated in the accommodating space.

[0072] It should be particularly and clearly stated that, in order to make the clamping between the first clamping block 412c and the bottom of the rail 30 more stable, the notch shape of the first clamping block 412c in the example should be adapted to the cross-sectional shape of the side of the bottom of the rail away from the avoidance space 40. In addition, in order to ensure the clamping effect when the first clamping block 412c is clamped with the bottom of the rail, an elastic buffer pad is provided on the side of the first clamping block 412c facing the notch. When in use, the clamping function can be achieved through the cooperation between the provided elastic buffer pad and the connecting plate 412a and the upper surface of the bottom of the rail.

[0073] Of course, in order to further ensure the clamping effect between the connecting plate 412a and the first clamping block 412c and the rail bottom, an electromagnet 70 can be set on the side surface of the connecting plate 412a facing the rail bottom. When the connecting plate 412a contacts the lower surface of the rail bottom, the electromagnet 70 is energized and magnetically attracted to the corresponding rail 30, thereby further improving the fixing effect between the clamping assembly 412 of the example of the utility model and the rail 30.

[0074] Of course, in some preferred embodiments, the connecting plate 412a is also provided with a universal wheel 412d that can drive the connecting plate 412a to move along the sleeper, and the height of the second telescopic member 412b in the retracted state is lower than the height of the universal wheel 412d, and the height of the universal wheel 412d is lower than the gap between the rail 30 and the rail bed 20.

[0075] In this embodiment, a universal wheel 412d is provided on the connecting plate 412a, and the height of the second telescopic member 412b in the retracted state is lower than the height of the universal wheel 412d, and the height of the universal wheel 412d is lower than the gap between the rail 30 and the rail bed 20, so that the utility model can contact the sleeper through the universal wheel 412d when in use, thereby avoiding the wear of the connecting plate 412a caused by direct contact between the connecting plate 412a and the sleeper, and improving the service life of the connecting plate 412a.

[0076] It should be particularly and clearly stated that, in this embodiment, the example universal wheels 412d should have at least two, and the multiple universal wheels 412d should be paired in pairs and arranged on both sides of the extension direction of the connecting plate 412a. Through this arrangement, the utility model can occupy a shorter height space, and improves the smoothness of the clamping assembly 412 passing through any gap between the rail bed 20 and the same rail 30.

[0077] In some preferred embodiments, the snap-in assembly 412 also includes a third telescopic member 412e and a second snap-in block 412f. The third telescopic member 412e is installed on a side of the connecting plate 412a close to the first telescopic end 212. The third telescopic member 412e extends along the connecting plate 412a in a direction away from the first telescopic end 212. The second snap-in block 412f is installed on the first telescopic end 212 of the third telescopic member 412e. The slot opening direction of the second snap-in block 412f is set toward the direction of the upper surface of the rail bottom of the rail 30 close to the avoidance space 40.
