[0031] In order to make the drawing simple, only the part related to the utility model is shown in each drawing, which does not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the components with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also can mean "more than one" situation.

[0032] Referring to Figures 1 to 8 , the embodiment provides a seamless line steel rail displacement rapid detection device, including double track mobile platform 1, displacement detection device and control module 3.

[0033] The dual-track mobile platform 1 is configured to be assembled onto the rail 4 and to be movable along the rail 4. Specifically, when in use, the dual-track mobile platform 1 can be installed on the seamless track rail 4 (hereinafter referred to as the rail 4) that needs to be inspected, and after being started, it can move on and along the rail 4; when not in use, the dual-track mobile platform 1 can be removed from the seamless track rail 4.

[0034] The displacement detection device includes two displacement detection modules 2, and the two displacement detection modules 2 correspond to the two rails 4 respectively, and the displacement detection modules 2 correspond to the main line and the switch area on the corresponding rail side. The two displacement detection modules 2 are installed on the double-track mobile platform 1, and each displacement detection module 2 includes three shooting components, which are respectively used to shoot labels on the rails 4, shoot labels on the main line, and shoot labels set in the switch area. Among them, for the convenience of description, the shooting component used to shoot labels on the rails 4 is called a rail shooting component, the shooting component used to shoot labels on the main line is called a main line shooting component, and the shooting component used to shoot labels in the switch area is called a switch shooting component. Specifically, the shooting component includes a camera and a light source, and the light source is used to illuminate the shooting area of ​​the camera in the same shooting component.

[0035] Preferably, the two displacement detection modules 2 are symmetrical about a symmetry plane when they are arranged, and the symmetry plane is a vertical plane parallel to or coincident with the travel direction of the dual-track mobile platform 1 on the rails 4 .

[0036] The two displacement detection modules 2 can be respectively installed on the dual-track mobile platform 1 through mounting structures, and the two mounting structures are symmetrical about the symmetry plane. Specifically, the mounting structure includes a support base 5 and a crossbeam. The crossbeam is connected to the top of the support base 5, and the bottom of the support base 5 is connected to the dual-track mobile platform 1. One end of the crossbeam extends out of the area directly above the dual-track mobile platform 1, and the corresponding displacement detection module 2 is installed on the extended area. Each displacement detection module 2 includes a rail shooting component, a mainline shooting component, a switch shooting component and a mounting base. The mounting base is installed on the corresponding crossbeam, and the rail shooting component, the mainline shooting component and the switch shooting component are respectively installed on the mounting base.

[0037] The two beams in the mounting structure are first beam 6 and second beam 7, respectively. They are arranged along the same straight line. Their mutually adjacent ends are fixedly connected by a connecting structure, while their mutually distal ends are used to mount corresponding displacement detection modules 2. Displacement detection modules 2 are heavy, and since they are mounted at the ends of the beams, connecting the two beams together balances the torque caused by the weight of the displacement detection modules 2.

[0038] Specifically in the embodiment, the connecting structure comprises at least one set of first connecting parts and second connecting parts. The first connecting part comprises a positioning hole 9 and a positioning column 8; the end surface of the first cross beam 6 facing the second cross beam 7 is a first connecting surface, and the end surface of the second cross beam 7 facing the first cross beam 6 is a second connecting surface; the first connecting surface and the second connecting surface are respectively provided with a positioning hole 9 and a corresponding positioning column 8, and the positioning column 8 extends into the positioning hole 9. The second connecting part is connected with the first cross beam 6 and the second cross beam 7 respectively, and is used to press the first connecting surface and the second connecting surface tightly to lock the relative position of the first cross beam 6 and the second cross beam 7. Specifically, the second connecting part comprises two ear plates 10, a connecting piece 11 and a connecting pin 12, the two ear plates 10 are connected with the first cross beam 6 and the second cross beam 7 respectively, one end of the connecting piece 11 is rotatably connected with one of the ear plates 10, the other end of the connecting piece 11 is provided with a connecting hole, and the connecting pin 12 penetrates through the two connecting holes, so as to press the first connecting surface and the second connecting surface tightly. Of course, other connecting structures can also be used in other embodiments, which are not limited here.

[0039] A handle 13 can also be arranged on the top of the first cross beam 6 and the second cross beam 7 respectively, so as to facilitate lifting and carrying the first cross beam and the second cross beam 7. The fixed connection between the support base 5 and the double-track moving platform 1 can be detachable connection such as bolt connection, so that when the device is not used, the first cross beam 6 and the second cross beam 7 can be detached from the double-track moving platform 1 and stored separately.

[0040] The double-track moving platform 1 is provided with a mileage meter device for measuring the distance traveled by the double-track moving platform 1 on the steel rail 4, and the control module 3 is installed on the double-track moving platform 1 and is signal-connected with the mileage meter device and the two displacement detection modules 2, so as to control the shooting assembly in the displacement detection module 2 to shoot according to the measurement data of the mileage meter device.

[0041] Specifically, the double-track moving platform 1 has wheels for rolling on the steel rail 4 to drive the double-track moving platform 1 to move on the steel rail 4; the mileage meter device is a mileage encoder arranged on the axle of the wheel. Of course, other mileage meter devices capable of obtaining the distance traveled by the double-track moving platform 1 on the steel rail 4 can also be used in other embodiments, which are not limited here.

[0042] On the seamless line steel rail 4, a label is arranged on the steel rail 4 and the main line / switch area at each position to be detected, that is, four labels are arranged at each position to be detected (two labels on the steel rail 4 and two labels on the main line on both sides, or two labels on the steel rail 4 and two labels on the switch area on both sides).

[0043] The control module 3 controls the camera assembly to take photos based on the distance the dual-track mobile platform 1 has traveled on the rails 4. Specifically, the distance traveled can be used to determine whether the platform is on the mainline or in the switch area. When on the mainline, the mainline camera assembly and the rail camera assembly are controlled to take photos continuously. When in the switch area, the switch camera assembly and the rail camera assembly are controlled to take photos continuously. In this embodiment, the cameras in the camera assembly can be triggered by pulses to take photos continuously. During the photo taking process, two sets of mainline camera assemblies and two sets of rail camera assemblies are controlled to take photos simultaneously, or two sets of switch camera assemblies and two sets of rail camera assemblies are controlled to take photos simultaneously. This means that four photos taken at the same time are obtained each time. If two of the four photos taken at the same time have corresponding labels on the photos taken by the rail camera assemblies and at least one of the mainline camera assembly and the switch camera assembly, the four photos in that group are considered valid photos and are referred to as a valid photo group. Measurements and calculations are performed on the valid photo group to determine the displacement of the two rails 4 at the detection location.

[0044] Preferably, all four photos in the valid photo group are valid photos. At this time, the photos taken of the labels of the rail 4 and the main line / switch area on the same side are divided into a group, and the two valid photos in the same group are compared respectively. The label on the main line / switch area is used as the benchmark, and the displacement of the label on the rail 4 compared with the label on the main line / switch area is measured and calculated. When the displacement difference exceeds the safety threshold, it means that the displacement of the rail 4 corresponding to the detection position is too large and needs to be paid special attention. Paying special attention means that it may need to be repaired later.

[0045] However, during the actual shooting process, the labels on the main line or the labels on the switch area may not be clearly photographed because they are far away from the displacement detection equipment. At this time, another method of measuring and calculating the displacement can be used: taking the label on the effective photo taken by one of the main line shooting components / switch shooting components as the benchmark, the labels on the effective photos taken by the two rail shooting components are compared with the labels used as the benchmark, and the displacement of the label on the rail 4 compared to the label on the main line / switch area is measured and calculated respectively. When the difference in displacement exceeds the safety threshold, it means that the displacement of the rail 4 corresponding to the detection position is too large and needs to be paid special attention.

[0046] As to how to process the photographed photos to obtain the displacement, the photos can be processed manually, and the displacement is obtained by manual calculation. However, the manual calculation is inefficient and inaccurate, and errors are prone to occur. Therefore, the manual method is not usually used in practical applications. Alternatively, after the seamless rail track displacement rapid detection device completes the inspection of the entire seamless rail track 4, the data obtained during the inspection, such as the photos, are migrated to an external computer, and the external computer performs identification, analysis, processing, and the like of the photographed photos, and then determines which positions have displacement exceeding the safety threshold and need to be processed. And the like.

[0047] In this embodiment, a processor, i.e., an industrial computer, is arranged in the control module 3 to process each group of obtained photos in real time. When it is detected that the group of photos is a valid photo group, the displacement is calculated and recorded. Figure 8 For a feasible electrical schematic diagram of this embodiment, the control module 3 includes the above-mentioned industrial computer, a voltage conversion circuit board card, a distribution control box, a speed mileage calculation board card, and the like, to complete the functions of trigger control (specifically, controlling the corresponding photographing assembly to take photos according to the mileage), data acquisition, speed display (the display screen used for display can be installed above the double-track mobile platform 1 to facilitate the observation of the staff), and the like.

[0048] During the running and detection of the seamless rail track displacement rapid detection device on the entire seamless rail track 4, a ledger is automatically generated in the industrial computer of the control module 3. When the displacement at a certain detection position exceeds the safety threshold, special marks and summaries are made on the ledger, so that the rail track 4 sections that need to be focused on can be checked after the detection is completed. Of course, when the displacement difference exceeds the safety threshold, a warning action such as sound and light can be performed, and then the staff on the double-track mobile platform 1 can manually record the rail track 4 sections that need to be focused on. The present application does not limit this. The ledger of the device is a tool or system for automatically recording and managing related information of the device by using information technology means, and can usually collect, organize, store, and analyze data in real time. How to design software and hardware to realize the function of the ledger has developed into a mature and widely used existing technology system, and how to design the ledger is not the focus of this embodiment. Therefore, this embodiment will not be described in detail.

[0049] The seamless rail track displacement rapid detection device provided in this embodiment is installed on the double-track mobile platform 1, and the displacement detection device and the control module 3 are installed on the double-track mobile platform 1. The displacement of the seamless rail track 4 is obtained by detecting the displacement observation marks (referred to as tags) arranged on the rail track 4 and the main line / switch region.

[0050] The seamless line rail displacement rapid detection device provided by the embodiment can control the displacement detection device to carry out image acquisition through the control module 3, and can carry out displacement amount calculation and display, and can record and alarm the displacement observation points (that is, the positions corresponding to the labels) exceeding the threshold value, so as to improve the detection efficiency and reduce the labor of the workers.

[0051] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments. Even if various changes are made to the utility model, provided that the changes belong to the range of the utility model claims and equivalent technologies, they still fall within the protection scope of the utility model.
