Example (b):
in engineering practice, because the actual track gauge of the rail is not completely consistent with the theoretical value, and the error range is generally +/-5-10 mm, in order to enable the rail inspection vehicle 100 to normally run, the distance between the limiting mechanisms on the left side and the right side must be at least 10mm smaller than the theoretical distance. The design enables the track inspection vehicle 100 to pass through smoothly without being stuck when the actual track gauge is the minimum value of-10 mm.
However, in general, the distance between both sides of the rail detecting vehicle 100 is smaller than the actual gauge, that is, there is always a gap between the limiting mechanism on both sides of the rail detecting vehicle and the inner side of the rail 200. The above-mentioned gap causes the position of the rail detecting vehicle 100 on the two rails 200 to change at any moment; that is, it may be left or right. The detecting instrument carried on the vehicle body can move left and right. It is because the measurement reference time of the detection instrument varies, and the error of the detection result is relatively large. Therefore, the present embodiment provides a novel rail inspection vehicle 100, the measurement reference of which can be kept unchanged; and thus measurement errors can be reduced.
Referring to fig. 1, the present embodiment provides a track inspection vehicle 100 for inspecting the state of a track 200 while traveling on the track 200; the rail inspection vehicle 100 includes a frame 110 and a running assembly 120, wherein the running assembly 120 includes a first running wheel 121 and a second running wheel 140, and the two running wheels are respectively disposed on two sides of the frame 110 for cooperating with two rails 200. And, the running wheels on one side are obliquely arranged, so that the track inspection vehicle 100 has a tendency of deviating to the left or the right when running along the track 200, and the running wheels of the track inspection vehicle 100 can run close to the inner side of the track 200 on one side.
Referring to fig. 2 to 6, the frame 110 of the rail inspection vehicle 100 includes a frame body 113, a first mounting member 111 and a second mounting member 112, wherein the frame body 113 is a bar-shaped structure, and the first mounting member 111 and the second mounting member 112 are arc-shaped rod structures; the middle portions of the first and second mounting members 111 and 112 are respectively coupled to both ends of the frame body 113. Both ends of the first mounting member 111 and the second mounting member 112 are used for mounting running wheels. Other instruments for rail 200 detection are provided on the frame 113, and a detailed description thereof will not be given since they can be directly purchased.
The running assembly 120 comprises two first running wheels 121 and two second running wheels 140, wherein the two first running wheels 121 are rotatably connected to both ends of the first mounting member 111 via a first axle 124, respectively, and the two second running wheels 140 are rotatably connected to both ends of the second mounting member 112 via a second axle, respectively.
Further, the running assembly 120 further includes a first coupling plate 122, a mounting hole is formed at an end of the first mounting member 111, one end of the first axle 124 is rotatably connected to the first running wheel 121 through a bearing, and the other end is fixedly connected to the first mounting member 111 through the first coupling plate 122.
Specifically, the first adapter plate 122 is connected to the first mounting member 111 by screws, and the first axle 124 is fixedly connected to the first adapter plate 122 by hexagonal nuts. Further, a gasket 123 is disposed between the mating surfaces of the first adapter plate 122 and the first mounting member 111; the shim 123 causes the mating surface of the first axle 124 with the first mounting member 111 to no longer be vertically disposed, but rather the first axle 124 tilts rearward in the horizontal plane, thereby causing the front portion of the first wheel to tilt leftward. The design makes the rail detecting vehicle 100 have a tendency of left deviation when running along the rail 200, so that the first running wheels 121 closely cling to the inner side surface of the left rail 200 to run. That is, the track inspection vehicle 100 runs with the left track 200 as a reference, which provides a certain reference for data inspection, and thus can improve the accuracy of measurement. In this embodiment, the shim 123 is a wedge-shaped shim 123, and the wedge-shaped shim 123 is sleeved on the rotating shaft, so that the wedge-shaped shim 123 is prevented from falling off; the inclination angle of the first running wheel 121 is 1.2 °.
The second running wheel 140 is mounted in a similar manner to the first running wheel 121, except that the second adapter plate is not provided with a shim 123 with the second mounting member 112 and the second axle is provided perpendicular to the mating surface of the second mounting member 112.
In addition, guide wheels 125 are provided on both the first mounting member and the second mounting member.
In other embodiments, the first axle 124 may also be tilted forward by using the shim 123. At this time, the front portion of the first wheel is inclined to the right, and the rail detecting vehicle 100 tends to be inclined to the right, so that the second running wheel 140 runs closely to the inner side surface of the right rail 200. In addition, the first and second running wheels of the first and second running wheels 121 and 140 in the present application are only for convenience of description, and are not particularly limited to the left-side running wheels or the right-side running wheels. In this embodiment, the first running wheels 121 are left running wheels.
In addition, in other embodiments, the track-inspecting vehicle 100 may be provided with only one first running wheel 121 and only one second running wheel 140.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
