In order to ensure the reliable operation of the electric locomotive, a roof detection system is arranged to periodically detect the roof condition of the electric locomotive, generally detect whether a roof pantograph carbon slide bar is cracked and damaged, detect whether a key part fastener is loosened, detect whether a roof has a foreign body, detect whether an important part is lost, detect whether the whole pantograph is seriously deformed, and the like. The detection system comprises a detection camera, and the angle and the position of the detection camera have great influence on the detection precision.
The application provides a connecting device for connecting a detection camera of a vehicle roof detection system. As shown, the connecting device includes: a fixing mechanism 100, a first adjustment mechanism 200, a second adjustment mechanism 300, and a third adjustment mechanism 400.
The fixing mechanism 100 is fixedly installed as an installation base of the entire connection device.
The first adjustment mechanism 200 is connected to the fixing mechanism 100 and is movable in the X direction relative to the fixing mechanism 100. The X direction is a horizontal direction, and may be a longitudinal direction or a transverse direction of the electric locomotive, for example.
The second adjustment mechanism 300 is connected to the first adjustment mechanism 200 and is movable in the Y direction relative to the first adjustment mechanism 200. The Y direction is a horizontal direction perpendicular to the X direction.
The third adjustment mechanism 400 is connected to the second adjustment mechanism 300 and is rotatable about the X direction with respect to the second adjustment mechanism 300, in other words, a rotation center line of the third adjustment mechanism 400 extends along the X direction.
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, so that the tilt angle of the inspection camera can be changed. When the second adjusting mechanism 300 moves along the Y direction, the third adjusting mechanism 400 connected to it also moves along the Y direction, so as to drive the detecting camera to move along the Y direction, thereby changing the Y position of the detecting camera. When the first adjusting mechanism 200 moves along the X direction, the first adjusting mechanism 200 connected to the first adjusting mechanism will move along the X direction, so as to drive the second adjusting mechanism 300, the third adjusting mechanism 400 and the detection camera to move along the X direction together, thereby changing the X direction position of the detection camera.
The connecting device is connected with the detection camera, and the pitching angle and the horizontal position of the detection camera can be flexibly adjusted according to different detection positions, so that the imaging quality of the detection camera can be guaranteed, and the detection precision of a roof detection system of the electric locomotive can be improved.
In the embodiment shown, a top beam 01 is provided, and during the detection, the electric locomotive is positioned below the top beam 01. The fixing mechanism 100 is fixedly installed by clamping the top beam 01, so that the installation reliability is high, and the looseness or deflection is not easy to happen. The method comprises the following steps: the top beam clamping arms 101 are arranged, the two sides of the top beam 01 are clamped by the top beam clamping arms 101, and the top beam clamping arms 101 and the top beam 01 are locked through first threaded fasteners 701. In the figure, top beam clamping arms 101 on both sides are connected into an integral top beam clamping part through connecting arms 102. The top beam clamping part is formed by welding plate pieces and is provided with lightening holes, so that the weight is light. The cross-sectional area of the top beam clamping arm 101 gradually increases from a position far away from the top beam 01 to a position close to the top beam 01 along the X direction, so that the connection reliability with the top beam is higher.
In the illustrated embodiment, the connection structure of the fixing mechanism 100 and the first adjusting mechanism 200 is: the fixing mechanism 100 is provided with two elongated holes a extending in the X direction, and the two elongated holes a are arranged in a staggered manner in the vertical direction perpendicular to the horizontal plane. The first adjusting mechanism 200 includes a U-shaped connecting plate 201, two longitudinal portions of the U-shaped connecting plate 201 are clamped on two sides of the fixing mechanism 100, two longitudinal portions are respectively provided with a group of connecting holes B, and the two groups of connecting holes B are respectively aligned and communicated with one strip-shaped hole a. The positions of the elongated hole a and the connection hole B may be reversed, that is, the elongated hole a may be provided in the first adjusting mechanism 200, and the connection hole B may be provided in the fixing mechanism 100. One set of second threaded fasteners 702 is coupled to one set of attachment holes B and one elongated hole a and the other set of second threaded fasteners 702 is coupled to the other set of attachment holes B and the other elongated hole a to thereby lock the securing mechanism 100 to the first adjustment mechanism 200. The connecting structure has the advantages of few parts, easy assembly and reliable connection. Of course, the connecting structure of the fixing mechanism 100 and the first adjusting mechanism 200 is not limited to this, and for example, the slide rail and the slide block may be adapted to be snapped together.
When the position of the detection camera in the X direction needs to be adjusted, the second threaded fastener 702 is loosened, and then the first adjusting mechanism 200 is moved in the X direction to drive the detection camera to move in the X direction; when the detection camera is moved to the target position along the X direction and then the second threaded fastener 702 is tightened, the position of the first adjusting mechanism 200 is fixed and cannot move along the X direction relative to the fixing mechanism 100 any more after the second threaded fastener 702 is tightened, so that the position of the X direction of the detection camera is stabilized.
In the illustrated embodiment, the connection structure between the second adjustment mechanism 300 and the first adjustment mechanism 200 is: the first adjusting 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 lateral portion of the U-shaped connecting plate 201, the other end is connected to the longitudinal portion of a U-shaped connecting block 302 described below, and a rib plate 203 is provided at the connection point. The second adjusting mechanism 300 is provided with a second sleeve 301 extending along the Y direction, and the second sleeve 301 is fittingly inserted into the first sleeve 202 and can move along the Y direction relative to the first sleeve 202. The first sleeve 202 and the second sleeve 301 are non-circular tubes (square tubes in the figure), so that the second sleeve 301 cannot rotate around the Y direction relative to the first sleeve 202 after being inserted into the first sleeve 202, and no rotation limiting component is required to be additionally arranged. The pipe wall of the first sleeve 202 and the pipe wall of the second sleeve 301 are provided with connecting holes for connecting the third threaded fasteners 703. The first sleeve 202 and the second sleeve 301 are locked by a third threaded fastener 703. By adopting the connecting structure, the wiring harness of the roof detection device can pass through the sleeve, and the sleeve plays a role in connecting and simultaneously plays a role in protecting the wiring harness and routing. Of course, the connecting structure of the first adjusting mechanism 200 and the second adjusting mechanism 300 is not limited to this, for example, the slide rail and the slide block may be adapted to be snapped together.
When the Y-direction position of the detection camera needs to be adjusted, the third threaded fastener 703 is loosened, and then the second adjustment mechanism 300 is moved along the Y-direction to drive the detection camera to move along the Y-direction; when the detection camera is moved to the target position along the Y direction and then the third threaded fastener 703 is tightened, the position of the second adjusting mechanism 300 is fixed after the third threaded fastener 703 is tightened, and the detection camera cannot move along the Y direction relative to the first adjusting mechanism 200 any more, so that the Y position of the detection camera is stabilized.
In the illustrated embodiment, the third adjustment mechanism 400 is connected to the inspection camera by clamping the inspection camera 02, so that the connection with the inspection camera is highly reliable and is not easily loosened or deflected. The method comprises the following steps: the detection camera clamping arms 401 are arranged, the two sides of the detection camera 02 are clamped by the detection camera clamping arms 401, and in the figure, the detection camera clamping arms 401 on the two sides are connected into an integral detection camera clamping part through a supporting arm 402. And, the inspection camera arm 401 and/or arm 402 are locked to the inspection camera 02 by a fourth threaded fastener 704.
In the illustrated embodiment, the third adjustment mechanism 400 is rotatably connected to the second adjustment mechanism 300 via a shaft and a shaft groove. Specifically, the second adjusting mechanism 300 is provided with a U-shaped connecting block 302, one longitudinal portion of the U-shaped connecting block 302 is connected to one end of a second sleeve 301 (in the figure, the second sleeve is inserted into the first sleeve 202), and the other longitudinal portion is provided with a U-shaped notch, and two sides of the U-shaped notch form notch side walls 302 a. The notch side walls 302a on two sides are provided with first shaft grooves, the two sides of the third adjusting mechanism 400 are provided with rotating shafts extending along the X direction, at least part of the third adjusting mechanism 400 is arranged in the U-shaped notch, and the rotating shafts on two sides are respectively arranged in the first shaft grooves on the same side and can rotate around the X direction in the first shaft grooves. The positions of the first shaft groove and the rotating shaft can be reversed, that is, the first shaft groove can be arranged on the third adjusting mechanism 400, and the rotating shaft can be arranged on the second adjusting mechanism 300. The first shaft groove is provided with the notch at one side, so that the rotating shaft is convenient to install. Of course, the connecting structure of the second adjusting mechanism 300 and the second adjusting mechanism is not limited to this, and for example, the first shaft groove may be replaced with a shaft hole.
In the illustrated embodiment, a first limiting mechanism 500 and a second limiting mechanism 600 are further provided, and after the third adjusting mechanism 400 drives the detection camera to rotate to the target angle around the X direction, the third adjusting mechanism 400 is locked by the first limiting mechanism 500 and the second limiting mechanism 600, so that the detection camera cannot be loosened due to the operation vibration of the electric locomotive.
Specifically, the first limiting mechanism 500 is provided with a second axial slot adapted to the rotating shaft, and the first limiting mechanism 500 is locked with the mechanism (in the figure, the second adjusting mechanism 300) provided with the first axial slot through a fifth threaded fastener 705.
When the angle of the detection camera needs to be adjusted, the fifth threaded fastener 705 is loosened, the third adjustment mechanism 400 is rotated around the X direction to drive the detection camera to a target angle, after the detection camera rotates to the target angle, the fifth threaded fastener 705 is screwed, and at this time, the second shaft groove and the first shaft groove clamp the rotating shaft, so that the third adjustment mechanism 400 cannot rotate around the X direction any more, and the detection camera is stabilized at the target angle.
Specifically, a position 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 the other position of the second limiting mechanism 600 (the other end of the second limiting mechanism 600 in the figure) is locked with the second adjusting mechanism 300 through a sixth threaded fastener 706. The third adjusting mechanism 300 is provided with a limit shaft D adapted to the limit hole E. The limiting shaft D extends along the X direction and is a non-circular shaft (a square shaft in the drawing, i.e., the cross section is a square surface), and the limiting shaft D and the limiting hole E are matched to limit the third adjusting mechanism 400 to rotate around the X direction. The positions of the limiting hole E and the limiting shaft D can be exchanged, that is, the limiting hole E can be arranged in the third adjusting mechanism 400, and the limiting shaft D is arranged in the second limiting mechanism 600.
Specifically, the hole of the third adjustment mechanism 400 for connecting the sixth threaded fastener 706 may be an arc-shaped hole C, so that the sixth threaded fastener 706 can slide along the arc-shaped hole C during the rotation of the third adjustment mechanism 400 in the X direction. With this arrangement, loosening the sixth threaded fastener 706 allows the third adjustment mechanism 400 to rotate about the X-direction without removing the sixth threaded fastener 706, and stepless adjustment of the angle of the detection camera can be achieved. The connection hole F of the second limiting mechanism 600 for connecting the sixth threaded fastener 706 may be an elongated hole.
Specifically, the limiting shaft D and the mechanism (in the figure, the second limiting mechanism 600) provided with the limiting hole E may be locked by a 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 may pass through the limiting hole E and then be screwed into the threaded hole at the end of the limiting shaft D, and the head of the seventh threaded fastener 707 directly abuts against the mechanism provided with the limiting hole E or indirectly abuts against the mechanism provided with the limiting hole E through the pressing plate 708 (in the figure, the head of the seventh threaded fastener 707 abuts against the second limiting mechanism 600 through the pressing plate 708).
