Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail with reference to the accompanying drawings.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, other ways of implementing the invention may be devised different from those described herein, and it will be apparent to those skilled in the art that the invention can be practiced without departing from the spirit and scope of the invention.

Furthermore, the references herein to "one embodiment" or "an embodiment" refer to a particular feature, structure, or characteristic that may be included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

Referring to fig. 1-2, as a first embodiment of the invention, a novel mine underground mine car is provided, which comprises a carriage 1 and a chassis 2 for mounting the carriage 1; the bottom of the chassis 2 is provided with a movable wheel 5, a rail cleaning device 6 and an inclined leg channel steel 4; a front coupler assembly 3 and a rear coupler assembly 8 are respectively arranged at the front and the rear of the chassis 2; the adjacent tramcars are connected with the front coupler assembly 3 of the next car through the rear coupler assembly 8 of the previous tramcar;

and the front car coupler assembly 3 and the rear car coupler assembly 8 are car coupler assemblies and are used for realizing automatic connection of adjacent mine cars.

Specifically, when the mine car is used, the automatic hooking and locking can be realized by the collision of front and rear adjacent vehicles.

The coupler assembly comprises a coupler head 10 and a coupler head box body 13;

a front baffle 12, a rear baffle 16 and a pull rod 14 penetrating through the front baffle 12 and the rear baffle 16 are arranged in the hook head box body 13; a spring 15 is arranged between the front baffle plate 12 and the rear baffle plate 16;

one end of the pull rod 14 is fixedly arranged at the bottom of the hook head box body 13 through a gasket 17 and a nut 18, and the other end of the pull rod is connected with the hook head 10 through a pin shaft 11;

the hook head 10 is provided with a hook tongue 9.

Specifically, the two springs 15 are respectively positioned on two sides of the pull rod 14, so that when the hook head 10 impacts, a buffering effect can be achieved, and the stress is more uniform; the separation between the hook head box body 13 and the hook head 10 can be realized by pulling out the pin shaft 11.

The front coupler assembly 3 and the rear coupler assembly 8 are respectively arranged at two ends of the central line of the chassis 2.
