Further, as shown in fig. 2 and 4, the fitting mechanism 3 may further include a collection tray 33, the collection mechanism 4 may be mounted on the collection tray 33, thereby further improving the stability of the acquisition mechanism 4, and in the process of assembling the data acquisition mechanism 4, the acquisition mechanism 4 can be connected to the acquisition bracket 33 first, then the two components are integrally and fixedly connected with two base frames 32 in the matching mechanism 3, the collecting bracket 33 can be made of hard materials such as metal and the like to ensure that the collecting bracket has higher structural strength and structural stability, furthermore, the collecting bracket 33 and the two base frames 32 can be fixedly connected together by welding, and the two base frames 32 are movably connected with the mounting frame 1 by the pressing part 2, so that the collecting bracket 33 can move relatively with the mounting frame 1 in the telescopic direction of the pressing part 2. In addition, in order to further improve the accuracy and the definition of the acquired data, it is preferable that, as shown in fig. 3, the acquisition mechanism 4 is centered with respect to the roller along the axial direction of the roller, specifically, the lens of the camera 41 is centered with respect to each of the engagement portions 31, in which case, the image acquired by the camera 41 can be relatively wider, and the definition of the acquired data such as the image can be higher and is not easily distorted.

Preferably, as shown in fig. 2, the embodiment of the present invention provides a data acquisition device further comprising a rotating shaft 6, wherein the rotating shaft 6 is used to form a rotating connection relationship between the acquisition bracket 33 and the mounting bracket 1 during the process of connecting the acquisition bracket 33 and the mounting bracket 1, and further during the working process of the data acquisition device, when the press-fit device is moved to the junction of the inlet section 91 and the horizontal section 92 in the third rail 9, or the junction of the horizontal section 92 and the outlet section 93, it can be ensured that the press-fit device is more rapid, and more stably forms a mutually perpendicular relationship with the third rail 9.

For example, during the process of the data acquisition equipment entering the horizontal segment 92 from the inlet segment 91, the engaging portion 31 located in front will move from the inlet segment 91 to the horizontal segment 92 earlier than the engaging portion 31 located in rear, because the inlet segment 91 is raised above the horizontal segment 92, and thus, under the influence of the structure of the third rail 9 itself, the engaging portion 31 located in front will exert a certain downward pressure on the pressing portion 2, so that its position is lower than that of the engaging portion 31 located in rear, and both engaging portions 31 are fixed relative to the acquisition bracket 33 through the corresponding base frames 32, at this time, because the acquisition bracket 33 and both mounting frames 1 are connected through the rotating shaft 6, when the engaging portion 31 located in front moves onto the horizontal segment 92, and the height of the engaging portion 31 located in front is unchanged, the height of the engaging portion 31 located in rear continues to decrease, therefore, the whole collecting bracket 33 can generate a certain rotation angle relative to the mounting frame 1, and further the stable close fit relation between the matching part 31 positioned at the rear and the third rail 9 can be ensured, and the orientation of the collecting mechanism 4 can be kept vertical to the inlet section 91 of the third rail 9 as far as possible until the matching part 31 positioned at the rear moves to the horizontal section 92, and the orientation of the collecting mechanism 4 can be completely vertical to the horizontal section 92.

Specifically, the base frame 32 may include two portions, one portion may be provided with a through hole to be sleeved on the guide rod, and the matching portion 31 may be installed on the other portion of the base frame 32, and the collecting bracket 33 may be fixedly connected between the respective other portions of the two base frames 32, and a rotation connection relationship may be formed between the two portions of the base frame 32 through the rotation shaft 6, so as to ensure that the collecting bracket 33 can rotate relative to the mounting frame 1. More specifically, as shown in fig. 2, the axial direction of the rotating shaft 6 and the extending and contracting direction of the pressing portion 2 may be made perpendicular to each other.

As described above, in the process of moving the whole matching mechanism 3 from the inlet section 91 to the horizontal section 92 and from the horizontal section 92 to the outlet section 93, it still inevitably happens that the acquisition mechanism 4 cannot be completely perpendicular to the partial structure of the third rail 9 opposite to itself, but considering that the moving speed of the train or the running gear driving the data acquisition mechanism 4 is relatively fast and the distance between the two matching portions 31 located in front and behind is relatively small compared with the length of the third rail 9, the time for the acquisition mechanism 4 to be incompletely perpendicular to the third rail 9 is relatively short and almost negligible.

In order to further reduce the adverse effect of the foregoing process on the data acquisition result, preferably, in the process of designing and producing the data acquisition device, under the condition that the acquisition mechanism 4 is ensured to have an acquisition angle meeting the requirement, the distance between the two matching parts 31 can be made as small as possible, so as to further shorten the length of the path (or time) of the acquisition mechanism 4 which is not completely perpendicular to the third rail 9, and further improve the overall accuracy and definition of the acquired data.

In the description of the present invention, it should be noted that the terms "upper", "lower", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
