as shown in fig. 14 to 16, this embodiment relates to a dual-purpose rail vehicle having substantially the same structure as that of embodiment 1, except that: the periphery of the axle shaft 24 of the split axle is provided with a protection mechanism 26 near one end of the axle main body 22, and the protection mechanism 26 comprises an outer sleeve 27 fixedly connected to the axle shaft 24 and an inner sleeve 28 sleeved on the outer sleeve 27; the spring 29 is arranged between the inner side surface of the inner sleeve 28 and the outer side surface of the outer sleeve 27, the springs 29 are uniformly distributed on the outer side surface of the inner sleeve 28, the inner sleeve 28 is in threaded connection with the end part of the outer sleeve 27, specifically, the end part of the inner sleeve 28 is provided with external threads, and the end part of the outer sleeve 27 is provided with internal threads, so that the threaded connection between the inner sleeve 28 and the outer sleeve 27 is realized. The above arrangement can effectively protect the axle shaft 24 when an impact is applied to the axle shaft 24 from the outside.
Example 3:
as shown in fig. 17, this embodiment relates to a dual-purpose rail vehicle having substantially the same structure as that of embodiment 1, except that: one end of a handle 33 of the tractor snow removing device 40 is connected with an up-and-down driving device 38 arranged on the side surface of the outer cylinder 30 through a connecting block 37, the handle 33 is detachably connected with the connecting block 37, and the handle 33 is connected with the connecting block 37 through a bolt 39. The up-down driving device 38 may be an electric push rod, an oil cylinder, an air cylinder, or the like. When the snow removing device is used, the positioning pin 34 is detached, and the handle 33 is driven to move up and down by the up-and-down driving device 38, so that the positions of the inner cylinder 31 and the snow removing plate 32 are adjusted, and the automatic adjustment of the position of the snow removing plate 32 is realized. When the upper and lower driving device 38 is damaged or cannot be started due to other reasons, the lower bolt 39 can be detached, the handle 33 is separated from the upper and lower driving device 38, the position of the snow removing plate 32 can be adjusted by manually adjusting the handle 33, and after adjustment, the snow removing plate is fixed through the positioning pin 34, so that the automatic adjustment and the manual adjustment are switched, and the normal operation of the work is ensured.
The foregoing embodiments are merely examples of the present invention, and the scope of the present invention includes, but is not limited to, the forms and styles of the foregoing embodiments, and any suitable changes or modifications made by those skilled in the art, which are consistent with the claims of the present invention, shall fall within the scope of the present invention.
