[0003] Currently, my country's onboard track geometry measurement systems are installed on comprehensive inspection vehicles. The sensors are mounted on a crossbeam, a heavy structure that requires ensuring the relative positioning of the sensors. The crossbeam is mounted on the vehicle's underside via a crane arm. A second mounting plate is located on the underside of the crossbeam, parallel to the vehicle's underside. The sensors are mounted on the underside of the crossbeam using a surface-fit method.

[0004] However, when the sensor needs to be repaired, it needs to be removed as a whole. When it is reinstalled, the sensor angle needs to be recalibrated, making the installation and debugging of the sensor more complicated. Utility Model Content

[0024] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0025] Example 1

[0026] like Figure 1 and Figure 2 As shown, a mounted track geometry monitoring structure is provided, comprising: a track geometry acquisition sensor 1 and a sensor bracket 2;

[0027] The sensor bracket 2 is arranged on the bottom surface of the vehicle body, and an inclined surface 204 is provided on the sensor bracket 2. The inclined surface 204 is inclined from one end close to the bottom surface of the vehicle body to the other end close to the bottom surface of the vehicle body along the direction away from the middle of the sensor bracket 2. A mounting plate 203 is provided on the inclined surface 204, and the mounting plate 203 is parallel to the inclined surface 204. A mounting plate 203 is provided on the inclined surface, and a mounting screw hole is provided on the mounting plate 203. An auxiliary screw hole is provided on the surface of the track geometry acquisition sensor 1, and a mounting bolt is provided in the mounting screw hole. The mounting bolt is passed through the mounting screw hole and the auxiliary screw hole, and the mounting bolt is threadedly connected to the mounting screw hole and the hole wall of the auxiliary screw hole, so that the acquisition end of the track geometry acquisition sensor 1 faces the surface of the track.

[0028] In this embodiment, the sensor bracket 2 is mounted on the bottom surface of the vehicle body, with a sloped surface 204 provided on the side of the sensor bracket 2. The sloped surface 204 has a first end proximal to the side of the sensor bracket 2 facing the vehicle body, and a second end proximal to the side of the sensor bracket 2 facing the track. The central axis of the sensor bracket 2 is perpendicular to the side of the sensor bracket 2 facing the vehicle body. The sloped surface 204 slopes from the first end to the second end, away from the center of the sensor bracket 2.

[0029] When the sensor bracket 2 is mounted on the bottom surface of the vehicle body and the sensor bracket 2 is located between the two rails, the plane where the inclined surface 204 is located intersects with one of the rails. The mounting plate 203 is mounted on the inclined surface 204, and the mounting plate 203 is parallel to the inclined surface 204. The surface of the track geometry acquisition sensor 1 is placed against the mounting plate 203, and the acquisition end of the track geometry acquisition sensor 1 is directed toward the surface of the rail. The position of the track geometry acquisition sensor 1 is adjusted so that the auxiliary screw hole in the track geometry acquisition sensor 1 is opposite to the mounting screw hole in the mounting plate 203. The mounting bolt is passed through the mounting screw hole and the auxiliary screw hole to fix the track geometry acquisition sensor 1 to the mounting plate 203.

[0030] like Figures 3 to 5 As shown, in one embodiment, it further includes a base 8, which is arranged on the bottom surface of the vehicle body. At least two connecting grooves 802 are provided on the side of the base 8 facing away from the vehicle body, and connecting threaded holes 803 are provided at the bottom of the connecting grooves 802;

[0031] The sensor bracket 2 is arranged on the side of the base 8 facing away from the vehicle body, and the side of the sensor bracket 2 facing the base 8 is provided with at least two connecting protrusions 201, each of the connecting protrusions 201 is respectively inserted into each of the connecting grooves 802, and a connecting hole is opened inside the connecting protrusion 201, and the connecting hole passes through the surface of the sensor bracket 2. A connecting bolt 9 is passed through the connecting hole, and the bolt head of the connecting bolt 9 abuts against the second side of the sensor bracket 2. The rod body of the connecting bolt 9 passes through the connecting hole and is threadedly connected to the hole wall of the connecting threaded hole 803.

[0032] In this embodiment, a base 8 is provided on the bottom surface of the vehicle body, and at least two connecting grooves 802 are defined on the second surface of the base 8. Connecting protrusions 201 protrude from the surface of the sensor bracket 2, and the diameter of the connecting protrusions 201 is smaller than the diameter of the connecting grooves 802, allowing the connecting protrusions 201 to be inserted into the connecting grooves 802.

[0033] When connecting the sensor bracket 2 to the base 8, adjust the position of the sensor bracket 2 relative to the base 8 so that the side of the sensor bracket 2 provided with the connecting protrusion 201 is parallel to the side of the base 8 provided with the connecting groove 802. Insert the connecting protrusion 201 on the sensor bracket 2 into the connecting groove 802 of the base 8. The plug-in fit of the multiple connecting protrusions 201 and the multiple connecting grooves 802 ensures that the sensor bracket 2 and the base 8 are relatively fixed. This facilitates the docking operation of the sensor bracket 2 and the base 8. When each connecting protrusion 201 is inserted into the corresponding connecting groove 802, the connecting hole and the connecting threaded hole 803 are aligned. Insert the connecting bolt 9 into the connecting hole and the connecting threaded hole 803, and rotate the connecting bolt 9 to thread the connecting bolt 9 into the wall of the connecting hole and the connecting threaded hole 803. The screw head of the connecting bolt 9 abuts the surface of the sensor bracket 2, fixing the sensor bracket 2 to the base 8.

[0034] like Figure 1 and Figure 2 As shown, in one embodiment, three connecting protrusions 201 are provided on the sensor bracket 2, and the three connecting protrusions 201 are distributed in a herringbone shape. Three connecting grooves 802 are provided on the base 8, and the three connecting grooves 802 are distributed in a herringbone shape. The three connecting protrusions 201 are respectively inserted into the three connecting grooves 802.

[0035] In this embodiment, the three connecting protrusions 201 and the three connecting grooves 802 are arranged in a herringbone shape. When the sensor bracket 2 is connected to the base 8, the herringbone-shaped connecting protrusions 201 can make the force distribution between the sensor bracket 2 and the base 8 more uniform and the connection more stable.

[0036] like Figure 1 and Figure 2 As shown, in one embodiment, the end of the connecting protrusion 201 is spherical.

[0037] In this embodiment, the end face of the connecting protrusion 201 is set to a spherical surface. When the connecting protrusion 201 abuts against the edge of the connecting groove 802 during the docking installation of the sensor bracket 2 and the base 8, the connecting protrusion 201 is designed to be a spherical surface, so that the connecting protrusion 201 can be inserted into the connecting groove 802 more quickly, reducing the difficulty of installing the sensor bracket 2 and the base 8.

[0038] In one embodiment, the bottom surface of the connecting groove 802 is a spherical surface.

[0039] In this embodiment, the bottom surface of the connecting groove 802 is set to a spherical surface, so that the position of the connecting protrusion 201 can be quickly adjusted when the connecting protrusion 201 is inserted into the connecting groove 802.

[0040] In one embodiment, the connecting groove 802 may be a square hole groove or a round hole groove.

[0041] In this embodiment, the connecting protrusion 201 is inserted into the connecting groove 802. When the connecting groove 802 is a square hole groove, the length of the shortest side of the square hole groove is greater than the diameter of the spherical surface. When the spherical surface of the connecting protrusion 201 abuts the edge of the connecting groove 802, the curvature of the spherical surface allows the connecting protrusion 201 to automatically insert into the connecting groove 802. When the connecting groove 802 is a round hole groove, the diameter of the connecting groove 802 is greater than the diameter of the spherical surface. After the connecting protrusion 201 is inserted into the connecting groove 802, the gap between the edge of the connecting groove 802 and each side wall of the connecting protrusion 201 is smaller, thereby facilitating precise assembly between the connecting protrusion 201 and the connecting groove 802.

[0042] like Figure 5 As shown, in one embodiment, a connection surface 801 is provided on a side of the base 8 facing the vehicle body, and the connection surface 801 is in a T-shape.

[0043] In this embodiment, the connection surface 801 of the base 8 faces the bottom surface of the vehicle body and is welded to the bottom surface of the vehicle body, so that the shape of the connection surface 801 is T-shaped, so that there is a wide contact area between the connection surface 801 and the bottom surface of the vehicle body, thereby increasing the connection strength between the base 8 and the vehicle body, which is beneficial to improving the stability of the sensor after the base 8 is installed.

[0044] like Figure 1 and Figure 2 As shown, in one embodiment, it further includes a first safety rope 3 , a first end of the first safety rope 3 is connected to the sensor bracket 2 , and a second end of the first safety rope 3 is connected to the track geometry acquisition sensor 1 .

[0045] In this embodiment, a first fixing point is provided on the side of the sensor bracket 2, and a first metal block 301 is provided at the first end of the first safety rope 3. The first metal block 301 is welded to the first fixing point. A connecting ridge 101 is provided on the surface of the track geometry acquisition sensor 1, and a second metal block 302 is provided at the second end of the first safety rope 3. The rope body of the second end of the first safety rope 3 abuts the surface of the connecting ridge 101, and the second metal block 302 is fixedly connected to the connecting ridge 101. The first safety rope 3 is used to increase the connection strength between the track geometry acquisition sensor 1 and the sensor bracket 2 to prevent the track geometry acquisition sensor 1 from detaching from the sensor bracket 2 due to vehicle vibration during use.

[0046] In one embodiment, a first hanging ear is provided on the sensor bracket, a second hanging ear is provided on the track geometry acquisition sensor, a first fastener is provided at the first end of the first safety rope, and a second fastener is provided at the second end of the first safety rope. The first fastener is passed through the first hanging ear, and the first fastener is fastened to the first safety rope, and the second fastener is passed through the second hanging ear, and the second fastener is fastened to the first safety rope.

[0047] In this embodiment, the sensor bracket is provided with a first lug protruding from the surface of the sensor bracket. The first lug may be a loop. A first fastener is provided at the first end of the first safety rope. The first fastener is inserted through the opening of the first lug and, after passing through the first lug, is folded in half and fastened to the first safety rope.

[0048] The track geometry acquisition sensor is provided with a second fastener, which can be a hanging ring. A second fastener is provided at the second end of the first safety rope, which is inserted through the opening of the first hanging ear. After passing through the second hanging ear, the second fastener is folded in half and clamped or fastened to the rope body of the first safety rope.

[0049] In one embodiment, a first limiting hole is provided on the sensor bracket, a second limiting hole is provided in the track geometry acquisition sensor, a first limiting block is provided at the first end of the first safety rope, and a second limiting block is provided at the second end of the first safety rope. The first end of the first safety rope is passed through the first limiting hole, and the size of the first limiting block is larger than the size of the first limiting hole. The second end of the first safety rope is passed through the second limiting hole, and the size of the second limiting block is larger than the size of the second limiting hole.

[0050] In this embodiment, a first retaining hole is defined in the sensor bracket, and the first end of the first safety rope is inserted into the first retaining hole. A first retaining block is provided on the first end of the first safety rope, and the size of the first retaining block is larger than the size of the first retaining hole. When the first retaining block abuts against the surface of the sensor bracket, the first retaining block cannot pass through the first retaining hole, thereby preventing the first safety rope from detaching from the sensor bracket.

[0051] The track geometry acquisition sensor has a second stopper hole, into which the second end of the first safety rope is inserted. A second stopper is provided at the second end of the first safety rope, with the size of the second stopper being larger than the size of the second stopper hole. When the second stopper abuts the surface of the track geometry acquisition sensor, the second stopper cannot pass through the second stopper hole, preventing the first safety rope from detaching from the track geometry acquisition sensor.

[0052] like Figure 4 and Figure 5As shown, in one embodiment, a second safety rope 7 is further included, a first end of the second safety rope 7 is connected to the base 8 , and a second end of the second safety rope 7 is connected to the sensor bracket 2 .

[0053] In this embodiment, a second fixing point is provided on the side of the base 8. The first end of the second safety rope 7 is connected to a third metal block 702, which is welded to the fixing point. The second end of the second safety rope 7 is connected to the side of the sensor bracket 2. The second safety rope 7 provides a more secure connection between the base 8 and the sensor bracket 2, preventing the sensor bracket 2 from detaching from the base 8 due to vehicle vibration.

[0054] like Figures 2 to 5 As shown, in one embodiment, a connecting hook 701 is provided at the second end of the second safety rope 7 , a connecting ring 202 is provided on the sensor bracket 2 , and the connecting hook 701 is hung in the connecting ring 202 .

[0055] In this embodiment, a connecting hook 701 is provided on the second end of the second safety rope 7. The connecting hook 701 may be a spring hook. When connecting the second end of the second safety rope 7 to the sensor, the connecting hook 701 is hooked into the connecting ring 202 on the sensor bracket 2. The connection between the connecting hook 701 and the connecting ring 202 allows for quick connection and disconnection of the second safety rope 7 from the sensor bracket 2.

[0056] like Figure 4 and Figure 5 As shown, in one embodiment, the number of the second safety ropes 7 is at least two, and the plurality of second safety ropes 7 are respectively arranged on different sides of the sensor bracket 2 .

[0057] In this embodiment, at least two second safety ropes 7 are used to connect the sensor bracket 2 and base 8. These ropes, positioned on different sides of the base 8, evenly distribute the forces between the sensor bracket 2 and base 8, reducing pressure on a single connection point and lowering localized stress concentration. Furthermore, the use of multiple second safety ropes 7 provides a multi-layered security mechanism: even if one rope fails, the remaining ropes can still secure the sensor bracket 2 to the base 8.

[0058] like Figure 3 As shown, in one embodiment, a control box 6 and a data cable 4 are further included, and the track geometry acquisition sensor 1 is electrically connected to the control box 6 via the data cable 4 .

The control box 6 obtains the track geometry data collected by the track geometry acquisition sensor 1 via the data cable 4. Utilizing the control box 6 and the data cable 4 facilitates centralized data transmission and control, simplifying system connection and maintenance.

[0060] In one embodiment, the control box 6 is electrically connected to the track geometry acquisition sensor 1 via a wireless communication module.

[0061] In this embodiment, wireless communication modules are provided in the control box 6 and the track geometry acquisition sensor 1. The control box 6 and the track geometry acquisition sensor 1 are electrically connected through the wireless communication module. The wireless communication module can be a 4G module or a 5G module.

[0062] like Figure 3 As shown, in one embodiment, a cable bracket 5 is provided on the base 8 , and the data cable 4 is provided in the cable bracket 5 .

[0063] In this embodiment, the cable bracket 5 is used to restrain the data cable 4 to prevent the data cable 4 from moving or shifting during installation or use. At the same time, by fixing the data cable 4 on the cable bracket 5, damage to the data cable 4 caused by dragging, stepping on, or mechanical pressure can be reduced.

[0064] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described.
