Description

Technical Field

[0001] This utility model relates to the field of rail damage monitoring technology, specifically to a rail damage monitoring sensor installation device. Background Technology

[0002] Nearly 20% of railway-related accidents occur on turnout sections. With the advent of high-capacity, high-speed railway operations, the need for monitoring the operational conditions of railway turnouts is increasingly prominent, and it is also one of the necessary means to prevent and reduce related accidents. The location of damage to railway turnouts is variable and develops rapidly; failure to provide timely warnings and handling may even lead to major safety accidents. Therefore, real-time damage monitoring of rails using monitoring sensors is a developing trend.

[0003] The sensor installation device for railway turnout monitoring and sensing equipment needs to be able to work for a long time in harsh outdoor environments, and to firmly connect the sensor to the rail to ensure accurate acquisition and smooth signal transmission. In addition, it also needs to be easy to install and easy to replace the sensor.

[0004] However, the existing rail damage monitoring sensor installation device cannot identify the monitoring direction of the sensor, which increases the difficulty of subsequent debugging and cannot well meet the usage requirements. Utility Model Content

[0005] The purpose of this utility model is to provide a rail damage monitoring sensor installation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rail damage monitoring sensor installation device includes: a sensor housing inserted into the rail, a mounting cavity provided inside the sensor housing, a positioning key provided inside the mounting cavity, a positioning groove provided at a corresponding position of the sensor, and a mark provided on the outer circumference of the sensor housing corresponding to the position of the positioning key; a cover plate fixed to the right side of the sensor housing at the position corresponding to the mounting cavity by countersunk screws; and a connecting assembly provided on the left side of the sensor housing for fixing the sensor housing to the rail.

[0008] As a preferred embodiment, the connecting assembly includes a sensor base inserted into the rail, the sensor base having a connecting recessed hole, a connecting bolt passing through the connecting recessed hole, and the end of the connecting bolt being threadedly connected to a connecting threaded groove on the left side of the sensor housing.

[0009] As a preferred embodiment, the connecting bolt is further fitted with a set of connecting gaskets, which includes a flat washer and a sealing gasket.

[0010] As a preferred embodiment, the right side of the sensor mount is also provided with a connecting chamfer.

[0011] As a preferred embodiment, a limiting slot is provided on the right side of the sensor base, and a limiting protrusion is provided on the corresponding position on the left side of the sensor housing. The limiting protrusion is inserted into the limiting slot.

[0012] As a preferred embodiment, the sensor base is provided with an identification hole.

[0013] As a preferred embodiment, the connecting bolts are coated with anti-loosening adhesive.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: By setting a limiting protrusion in conjunction with a limiting slot and a marking hole, the sensor housing is easily positioned, ensuring that the marking direction is parallel to the extension direction of the rail. This achieves parallelism between the sensor's monitoring direction and the rail's extension direction, facilitating monitoring operations. The connecting assembly allows for easy installation of the sensor housing onto the rail, simplifying operation and facilitating assembly and disassembly. This utility model has a reasonable structure, is easy to install, and facilitates marking the sensor's monitoring direction, better meeting usage requirements. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1-6 A rail damage monitoring sensor installation device includes: a sensor housing 2 inserted into a rail 1, a mounting cavity 21 provided inside the sensor housing 2, a positioning key 22 provided inside the mounting cavity 21, a positioning groove 31 provided at a corresponding position of the sensor 3, a mark 23 provided on the outer circumference of the sensor housing 2 corresponding to the position of the positioning key 22, and a cover plate 24 fixed on the right side of the sensor housing 2 corresponding to the position of the mounting cavity 21 by countersunk screws 25; and a connecting assembly provided on the left side of the sensor housing for fixing the sensor housing to the rail. In this embodiment, the monitoring direction of the sensor 3 is on the same straight line as the positioning groove 31 and opposite to the orientation of the positioning groove 31.

[0024] The working principle of this utility model is as follows: In specific use, the sensor 3 is inserted into the mounting cavity 21, and then the cover plate 24 is fixed to the sensor housing 2 by the countersunk screw 25, thus completing the fixing of the sensor 3. Then, the sensor housing 2 is inserted into the mounting hole opened on the rail web of the rail 1. Then, the sensor housing 2 is adjusted so that the plane where the mark 23 is located is perpendicular to the extension direction of the rail, thus realizing the horizontal setting of the monitoring direction of the sensor 3. At this time, the direction corresponding to the back side of the mark 23 is the monitoring direction of the sensor 3. Finally, the sensor housing 2 is fixed to the rail 1 by the connecting component, thus completing the installation.

[0025] As a further embodiment, the connecting assembly includes a sensor base 4 inserted into the rail 1. The sensor base 4 has a connecting recessed hole 45, and a connecting bolt 41 passes through the connecting recessed hole 45. The end of the connecting bolt 41 is threadedly connected to the connecting threaded groove 27 on the left side of the sensor housing 2. In this embodiment, a connecting gasket set 411 is also fitted on the connecting bolt 41. The connecting gasket set 411 includes a flat washer and a sealing gasket. In this embodiment, the connecting bolt 41 is coated with anti-loosening adhesive.

[0026] During connection, first insert the sensor seat 4 into the mounting hole on the rail 1, then apply a layer of loosening adhesive to the connecting bolt 41, then put the connecting washer set 411 on the connecting bolt 41, then insert the connecting bolt 41 into the connecting countersunk hole 45, and rotate the connecting bolt 41 so that the end of the connecting bolt 41 is screwed into the connecting thread groove 27, thus completing the connection. By setting the anti-loosening adhesive, the connection effect can be improved.

[0027] To facilitate the insertion of the sensor base 4 into the mounting hole on the rail 1, a connecting chamfer 43 is also provided on the right side of the sensor base 4.

[0028] As a further solution, a limiting slot 44 is provided on the right side of the sensor base 4, and a limiting protrusion 26 is provided on the corresponding position on the left side of the sensor housing 2. The limiting protrusion 26 is inserted into the limiting slot 44. By setting the limiting protrusion 26 in conjunction with the limiting slot 44, the sensor housing 2 can be constrained to prevent it from rotating relative to the sensor base 4, making it easier to determine the monitoring direction of the sensor 3.

[0029] To facilitate determining the orientation of the sensor base 4, an identification hole 42 is provided on the sensor base 4. In this embodiment, a vertical positioning mark line is provided at the mounting hole position on the rail 1. The identification hole 42 and the limiting protrusion 26 are located on the same horizontal plane. During assembly, by ensuring that the identification hole 42 is vertically upward (the identification hole 42 points to the positioning mark line), the limiting protrusion 26 can be ensured to be vertically set. At this time, it can be ensured that the monitoring direction of the sensor 3 is parallel to the extension direction of the rail 1.

[0030] In this utility model, terms such as "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "side", and "bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
