Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a bogie for a mine car, comprising: a bogie for a mine car comprises two wheels 1, steel rails 2 are arranged on the adjacent end faces of the two wheels 1, a sliding bush 3 is arranged in the middle of each wheel 1, an axle box bearing 4 is arranged on the sliding bush 3, an axle box body 5 is arranged on the axle box bearing 4, a locking device is arranged on the axle box body 5 and comprises a locking rod 6, a working arm 7, a node 8, a driving arm 9, a connecting rod 10, a spring 11, a first stop block 12 and a second stop block 13, an axle box rotating arm is arranged on the upper side of the axle box body 5, the upper side of the axle box rotating arm is arranged on a framework, the transverse force transmission path of a bogie wheel pair is changed greatly, and when the locking device locks the inner side distance of the wheel pair, the locking device bears the function of originally bearing the transverse force of the wheel rail by the interference connection of a wheel shaft, so that the bogie wheel rail transverse force transmission function is a core component for the safe operation of the whole bogie, in order to ensure the safe operation of the mine car, after the track gauge is locked, the track gauge should be kept stable, and the condition of accidental unlocking cannot occur, so that when a locking device is designed, the upward movement of the locking rod 6 is converted into the downward movement of the driving arm 4 by adding the driving arm 4, and the spring 11 still keeps a compression state in a locking state.
Specifically, the upper side of the lock lever 6 is provided with a cylindrical key 14.
