Abstract
Description
Technical Field
[0001] This utility model belongs to the field of track detection technology, specifically relating to an intelligent track detector. Background Technology
[0002] Trains run on tracks, and the condition of the tracks plays a crucial role in the train's operation. To improve safety, the tracks are usually inspected regularly by testing devices.
[0003] Existing technologies, such as Chinese Patent No. CN218298127U, disclose a track surface defect detection device that uses a mobile device to move a camera along the track to detect track surface defects. While this technology can identify track surface defects, when a defect is encountered, its location is typically displayed on an external computer. The location is then manually recorded before the user moves to the defect location for repair. However, manually recording the location usually involves pre-recording track segments and then moving to those segments to find the defect, which is difficult to do quickly and efficiently.
[0004] Therefore, a smart track detector is needed to solve the above problems. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a track intelligent detector that, by setting a marking component, enables a person to identify the defect location at a glance when walking to the corresponding track segment so as to repair the track.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] This utility model provides a track intelligent detector, including a mobile trolley capable of moving along the track. The mobile trolley includes a top plate disposed above the track, with a gap between the top plate and the top of the track. A detection element for detecting track surface defects is installed on the top plate near the head of the track. A marking assembly is disposed on the top plate on one side of the detection element. The marking assembly includes a drive mechanism fixedly connected to the top plate. The output end of the drive mechanism is fixedly connected to the marking element. The drive mechanism is used to output linear motion to move the marking element to the top wall of the head of the track to make a mark.
[0008] Furthermore, a sleeve is fixedly connected to the output end of the drive mechanism, the marker is slidably connected inside the sleeve, and a spring is fixedly connected between the marker and the inner wall of the sleeve.
[0009] Furthermore, the top plate is provided with a through hole, and the sleeve is slidably connected in the through hole.
[0010] Furthermore, the drive mechanism is fixedly connected to the top wall of the top plate by bolts, and the output end of the drive mechanism extends into the through hole and is fixedly connected to the sleeve.
[0011] Furthermore, a connecting plate is keyed inside the sleeve, the spring is fixedly connected between the top wall of the sleeve and the connecting plate, and the marking element is threadedly connected to the connecting plate.
[0012] Furthermore, the connecting plate is threadedly connected to a screw on the side away from the spring, and the marking element is provided with a threaded groove that mates with the screw thread.
[0013] Furthermore, the diameter of the marking element is consistent with the inner diameter of the sleeve.
[0014] Furthermore, the detection device includes a camera.
[0015] Furthermore, the detection device includes an electromagnetic ultrasonic probe.
[0016] The beneficial effects of this utility model are as follows:
[0017] This invention uses a marker to mark the track head when a defect is detected on the track surface. This allows the marker to be moved to the top wall of the track head by a drive mechanism, making a mark so that manual maintenance personnel can quickly locate the defect when they reach the corresponding track segment.
[0018] Other advantages, objectives, and features of this invention will be set forth in the following description and will be apparent to those skilled in the art to some extent, or may be learned by practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0023] like Figures 1-2 As shown, this utility model provides a track intelligent detector, including: a mobile trolley 1 capable of moving along a track, the mobile trolley 1 including a top plate 3 disposed above a track 2, a detection element 4 for detecting track surface defects installed on the top plate 3 near the track head 201, two connecting plates 5 respectively extending to the track waist 202 fixedly connected to the top plate 3, and a moving wheel 6 that fits against the track waist 202 disposed on the connecting plate 5 near the track waist 202. The method of the mobile trolley 1 moving stably along the track is a conventional technical means in the art and will not be described in detail here. A marking assembly is disposed on the top plate 3, the marking assembly including a drive mechanism 7 fixedly connected to the top plate 3, a marking element 701 fixedly connected to the output end of the drive mechanism 7, the drive mechanism 7 being used to output linear motion to move the marking element 701 to the track head 201 to make a mark.
[0024] In this scheme, the detection component 4 is electrically connected to an external computer via a control system, enabling the external computer to acquire detection information through the detection component 4. When the detection component 4 detects a defect on the track surface, the external computer controls the moving trolley 1 to stop moving and activates the drive mechanism 7, driving the marker 701 to move closer to the track head 201. When the marker 701 contacts the track head 201, it leaves a mark on the track head 201. Then, the computer control system controls the marker 701 to return to its original position and controls the moving trolley 1 to continue moving along the track 2. The control principle of the control system is a conventional technique in this field and will not be elaborated here. The detection component 4 can be a camera, which captures an image of the track 2 surface and transmits it to a computer for image recognition to determine the presence of defects. Alternatively, the detection component 4 can be an electromagnetic ultrasonic (EMAT) probe, which uses transverse waves introduced into the track 2. When the wave encounters a material interface or defect, some energy is reflected back. By analyzing the intensity, time, and phase characteristics of these reflected signals, the presence of cracks or other defects inside the track can be accurately determined. The detection principle of electromagnetic ultrasonic probes is a conventional technique in this field and will not be elaborated upon here. This solution improves detection efficiency and accuracy by using four detection components for intelligent detection of defects on the track surface, while reducing errors from manual inspection.
[0025] In one embodiment of the present invention, the output end of the drive mechanism 7 is fixedly connected to a sleeve 702, the marker 701 is slidably connected inside the sleeve 702, and a spring 703 is fixedly connected between the marker 701 and the inner wall of the sleeve 702.
[0026] In this design, the drive mechanism 7 is an electric cylinder for outputting linear motion. The model of the electric cylinder can be selected according to actual needs. The marking element 701 can be a marker pen. In the initial state of the marking element 701, the distance between the top of the marking element 701 and the top of the track head 201 is less than the output distance of the electric cylinder. This setting ensures that after the electric cylinder moves the marking element 701, after the marking element 701 abuts against the top of the track head 201, the electric cylinder continues to move to compress the spring 703, increasing the pressure of the marking element 701 on the track head 201, which facilitates marking. It also avoids damage to the marking element 701 due to excessive output displacement of the electric cylinder, and prevents the marking element 701 from failing to mark the top of the track head 201 due to insufficient output displacement of the electric cylinder. This design allows for quick manual detection of defects by marking the top of the track head 201. After the mark is found, the defective location is repaired and the mark is wiped off.
[0027] In one embodiment of the present invention, the top plate 3 is provided with a through hole 301, the sleeve 702 is slidably connected in the through hole 301, the driving mechanism 7 is fixedly connected to the top wall of the top plate 3 by bolts, and the output end of the driving mechanism 7 extends into the through hole 301 and is fixedly connected to the sleeve 702.
[0028] In this design, a through hole 301 is provided to ensure the stability of the sleeve 702 during the sliding process, and the drive mechanism 7 is located on the top wall of the top plate 3 for easy disassembly.
[0029] In one embodiment of the present invention, a connecting plate 704 is keyed to the inner sleeve 702, the spring 703 is fixedly connected between the inner top wall of the sleeve 702 and the connecting plate 704, and the marking member 701 is threadedly connected to the connecting plate 704.
[0030] In this design, the connecting plate 704 is threadedly connected to a screw 705 on the side away from the spring 703, and the marking member 701 is provided with a threaded groove 706 that is threadedly engaged with the screw 705, so that the marking member 701 can be connected to or disconnected from the connecting plate 704 by rotating the thread, which facilitates the replacement of the marking member 701.
[0031] In one embodiment of the present invention, the diameter of the marking member 701 is the same as the inner diameter of the sleeve 702, so as to facilitate the alignment of the threaded groove 706 and the screw 705.
[0032] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
