[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] To ensure reliable operation of electric locomotives, a roof inspection system is installed to regularly inspect the roof of the locomotive. This system typically checks for cracks and defects in the carbon sliding strips of the pantograph, loose fasteners on key components, foreign objects on the roof, missing important components, and severe deformation of the pantograph. The inspection system includes an inspection camera, whose angle and position significantly influence inspection accuracy.

[0030] The present application provides a connection device for connecting a detection camera of a vehicle roof detection system. As shown in the figure, the connection device includes: a fixing mechanism 100, a first adjustment mechanism 200, a second adjustment mechanism 300, and a third adjustment mechanism 400.

[0031] The fixing mechanism 100 is fixedly installed and serves as the installation basis of the entire connecting device.

[0032] The first adjustment mechanism 200 is connected to the fixing mechanism 100 and can move relative to the fixing mechanism 100 along the X direction. The X direction is a horizontal direction, for example, the longitudinal direction or the transverse direction of the electric locomotive.

[0033] The second adjustment mechanism 300 is connected to the first adjustment mechanism 200 and can move relative to the first adjustment mechanism 200 along the Y direction. The Y direction is a horizontal direction perpendicular to the X direction.

[0034] The third adjustment mechanism 400 is connected to the second adjustment mechanism 300 and can rotate relative to the second adjustment mechanism 300 about the X direction. In other words, the rotation centerline of the third adjustment mechanism 400 extends along the X direction.

[0035] The inspection camera is connected to the third adjustment mechanism 400. When the third adjustment mechanism 400 rotates in the X direction, the inspection camera rotates accordingly, thereby changing the inspection camera's pitch angle. When the second adjustment mechanism 300 moves in the Y direction, the third adjustment mechanism 400 connected thereto also moves in the Y direction, driving the inspection camera in the Y direction, thereby changing the inspection camera's Y position. When the first adjustment mechanism 200 moves in the X direction, the first adjustment mechanism 200 connected thereto also moves in the X direction, driving the second adjustment mechanism 300, the third adjustment mechanism 400, and the inspection camera in the X direction, thereby changing the inspection camera's X position.

[0036] By using this connecting device to connect the detection camera, the pitch angle and horizontal position of the detection camera can be flexibly adjusted according to different detection positions, thereby ensuring the imaging quality of the detection camera, and thus improving the detection accuracy of the roof detection system of the electric locomotive.

[0037] In the illustrated embodiment, a top beam 01 is provided, and during the inspection, the electric locomotive is located below the top beam 01. The fixing mechanism 100 achieves fixed installation by clamping the top beam 01, so that the installation reliability is high and it is not easy to loosen or deflect. Specifically, a top beam clamping arm 101 is provided, and the top beam clamping arm 101 is used to clamp the two sides of the top beam 01, and the top beam clamping arm 101 and the top beam 01 are locked by the first threaded fastener 701. In the figure, the top beam clamping arms 101 on both sides are connected to form an integral top beam clamping part by a connecting arm 102. The top beam clamping part is formed by welding plates and is provided with weight-reducing holes, so that it is lighter. The cross-sectional area of the top beam clamping arm 101 gradually increases along the X direction from a position away from the top beam 01 to a position close to the top beam 01, so that the connection reliability with the top beam is higher.

[0038] In the illustrated embodiment, the connection structure between the fixing mechanism 100 and the first adjustment mechanism 200 is as follows: the fixing mechanism 100 is provided with two elongated holes A extending along the X-direction, staggered in a vertical direction perpendicular to the horizontal plane. The first adjustment mechanism 200 comprises a U-shaped connecting plate 201. The two longitudinal portions of the U-shaped connecting plate 201 engage with either side of the fixing mechanism 100. Each of the two longitudinal portions is provided with a set of connecting holes B, each aligned and communicating with a respective elongated hole A. The positions of the elongated holes A and B can be reversed, that is, the elongated holes A can be provided in the first adjustment mechanism 200 and the connecting holes B in the fixing mechanism 100. A set of second threaded fasteners 702 is connected to one set of connecting holes B and one elongated hole A, while another set of second threaded fasteners 702 is connected to the other set of connecting holes B and the other elongated hole A, thereby locking the fixing mechanism 100 and the first adjustment mechanism 200. This connection structure has few components, is easy to assemble, and provides a reliable connection. Of course, the connection structure between the fixing mechanism 100 and the first adjustment mechanism 200 is not limited thereto, for example, a structure in which the slide rail and the slider are adapted to be snap-fitted is also acceptable.

[0039] When the X-direction position of the inspection camera needs to be adjusted, the second threaded fastener 702 is loosened, and then the first adjustment mechanism 200 is moved along the X-direction to drive the inspection camera to move along the X-direction; after the inspection camera is moved to the target position along the X-direction, the second threaded fastener 702 is tightened. After the second threaded fastener 702 is tightened, the position of the first adjustment mechanism 200 is fixed and can no longer move along the X-direction relative to the fixing mechanism 100, thereby stabilizing the X-direction position of the inspection camera.

[0040] In the illustrated embodiment, the connection structure between the second adjustment mechanism 300 and the first adjustment mechanism 200 is as follows: the first adjustment mechanism 200 is provided with a first sleeve 202 extending in the Y direction. One end of the first sleeve 202 is connected to the transverse portion of the U-shaped connecting plate 201, and the other end is connected to the longitudinal portion of the U-shaped connecting block 302 described below. Ribs 203 are provided at the connection points. The second adjustment mechanism 300 is provided with a second sleeve 301 extending in the Y direction. The second sleeve 301 is adaptably plugged into the first sleeve 202 and can move relative to the first sleeve 202 in the Y direction. The first sleeve 202 and the second sleeve 301 are non-circular tubes (square tubes in the figure). Therefore, once plugged into the first sleeve 202, the second sleeve 301 cannot rotate relative to the first sleeve 202 in the Y direction, eliminating the need for a separate rotation-limiting component. The walls of both the first sleeve 202 and the second sleeve 301 are provided with connection holes for connecting the third threaded fastener 703. The first sleeve 202 and the second sleeve 301 are locked together by a third threaded fastener 703. With this connection structure, the wiring harness of the roof detection device can pass through the sleeve, which not only connects the harness but also protects and routes the wiring. Of course, the connection structure of the first adjustment mechanism 200 and the second adjustment mechanism 300 is not limited to this; for example, a structure in which the slide rail and slider are adapted to snap together can also be used.

[0041] When it is necessary to adjust the Y-direction position of the inspection camera, loosen the third threaded fastener 703, and then move the second adjustment mechanism 300 along the Y-direction to drive the inspection camera to move along the Y-direction; after the inspection camera is moved to the target position along the Y-direction, tighten the third threaded fastener 703. After the third threaded fastener 703 is tightened, the position of the second adjustment mechanism 300 is fixed and can no longer move along the Y-direction relative to the first adjustment mechanism 200, thereby stabilizing the Y-direction position of the inspection camera.

[0042] In the illustrated embodiment, the third adjustment mechanism 400 connects to the inspection camera 02 by clamping it. This ensures a highly reliable connection with the inspection camera and is less likely to loosen or deflect. Specifically, a camera clamping arm 401 is provided to clamp both sides of the inspection camera 02. In the figure, the two arms 401 are connected by a support arm 402 to form a single, integrated camera clamping unit. Furthermore, the camera clamping arm 401 and / or the support arm 402 are secured to the inspection camera 02 via a fourth threaded fastener 704.

[0043] In the illustrated embodiment, the third adjustment mechanism 400 is rotatably connected to the second adjustment mechanism 300 via a rotating shaft and an axis slot. Specifically, the second adjustment mechanism 300 includes a U-shaped connecting block 302. One longitudinal portion of the U-shaped connecting block 302 is connected to one end of the second sleeve 301 (in the figure, the second sleeve is inserted into the first sleeve 202). The other longitudinal portion is provided with a U-shaped notch, with sidewalls 302a formed on either side of the notch. The sidewalls 302a on either side of the notch are provided with first axis slots. Rotating shafts extending along the X-direction are provided on either side of the third adjustment mechanism 400. The third adjustment mechanism 400 is at least partially mounted within the U-shaped notch, with the rotating shafts on either side being mounted in the first axis slots on the same side and capable of rotating in the X-direction within the first axis slots. The positions of the first axis slots and the rotating shaft are reversible; that is, the first axis slot can be provided in the third adjustment mechanism 400, while the rotating shaft can be provided in the second adjustment mechanism 300. The first axis slot has a notch on one side, which facilitates the installation of the rotating shaft. Of course, the second adjustment mechanism 300 and the second connection structure are not limited thereto. For example, the first shaft groove may be replaced by a shaft hole.

[0044] In the illustrated embodiment, a first limiting mechanism 500 and a second limiting mechanism 600 are further provided. When the third adjusting mechanism 400 drives the detection camera to rotate around the X direction to the target angle, the first limiting mechanism 500 and the second limiting mechanism 600 are used to doubly lock the third adjusting mechanism 400, so that the detection camera will not loosen due to the running vibration of the electric locomotive.

[0045] Specifically, the first limiting mechanism 500 is provided with a second shaft groove adapted to the above-mentioned rotating shaft, and the first limiting mechanism 500 is locked with the mechanism provided with the above-mentioned first shaft groove (the second adjustment mechanism 300 in the figure) through the fifth threaded fastener 705.

[0046] When the angle of the inspection camera needs to be adjusted, the fifth threaded fastener 705 is loosened, and the third adjustment mechanism 400 is rotated around the X direction to move the inspection camera to the target angle. When the inspection camera is rotated to the target angle, the fifth threaded fastener 705 is tightened. At this time, the second shaft groove and the first shaft groove clamp the rotating shaft, so that the third adjustment mechanism 400 can no longer rotate around the X direction, thereby stabilizing the inspection camera at the target angle.

[0047] Specifically, a portion of the second limiting mechanism 600 (one end of the second limiting mechanism 600 in the figure) is provided with a limiting hole E, and another portion of the second limiting mechanism 600 (the other end of the second limiting mechanism 600 in the figure) is locked to the second adjustment mechanism 300 via a sixth threaded fastener 706. The third adjustment mechanism 300 is provided with a limiting shaft D that is compatible with the limiting hole E. The limiting shaft D extends along the X-direction and is a non-circular shaft (a square shaft in the figure, i.e., a square cross-section). The limiting shaft D cooperates with the limiting hole E to limit the rotation of the third adjustment mechanism 400 about the X-direction. The positions of the limiting hole E and the limiting shaft D can be reversed, that is, the limiting hole E can be provided in the third adjustment mechanism 400, and the limiting shaft D can be provided in the second limiting mechanism 600.

[0048] Specifically, the hole in the third adjustment mechanism 400 for connecting to the sixth threaded fastener 706 can be an arcuate hole C, so that the sixth threaded fastener 706 can slide along the arcuate hole C during the third adjustment mechanism 400's rotation in the X-direction. This design allows the third adjustment mechanism 400 to rotate in the X-direction by loosening the sixth threaded fastener 706 without removing it, further enabling stepless adjustment of the detection camera angle. The connection hole F in the second limiting mechanism 600 for connecting to the sixth threaded fastener 706 can be an elongated hole.

[0049] Specifically, the limiting shaft D and the mechanism provided with the limiting hole E (the second limiting mechanism 600 in the figure) can be locked by the seventh threaded fastener 707 to prevent the limiting shaft D and the limiting hole E from being separated. Specifically, the threaded section of the seventh threaded fastener 707 passes through the limiting hole E and is tightened into the threaded hole at the end of the limiting shaft D. The head of the seventh threaded fastener 707 directly presses against the mechanism provided with the limiting hole E or indirectly presses against it via a pressure plate 708 (the head of the seventh threaded fastener 707 presses against the second limiting mechanism 600 via the pressure plate 708 in the figure).
