Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention will be more clearly and clearly defined.
Referring to fig. 1-2, the mining narrow gauge track terminal car stopper of the invention comprises:
the upper surface of the base plate 1 is provided with a track 2, and a mining vehicle 3 runs on the track 2;
a fixing plate 4 mounted on the base plate 1 and located at a middle position of the rail 2;
a connecting seat 5 fixedly connected to the upper surface of one side of the fixing plate 4;
the car stopping claw 6 comprises a connecting section 61 and a car stopping section 62, the bottom of one side of the car stopping section 62 is connected with the connecting section 61, the connecting section 61 is rotatably connected with the connecting seat 5 through a connecting pin 7, and the bottom of the other side of the car stopping section 62 is provided with a boss 63;
one end of the damping buffer spring 8 is connected with the boss 63, and the other end of the damping buffer spring 8 is connected with the upper surface of the other side of the fixed plate 4;
wherein the floor position of the mining vehicle 3 corresponds to the lower position of the stopper section 62.
In the invention, when the mining vehicle 3 runs to a line terminal of the track 2 to impact the car stopping claw 6, the bottom plate of the mining vehicle 3 is in contact with the lower part of the car stopping section 62 of the car stopping claw 6, the car stopping section 62 is pushed to rotate around the connecting seat 5, and the car stopping section 62 is driven to buffer and damp the mining vehicle 3 under the elastic acting force of the damping buffer spring 8, so that the mining vehicle 3 is decelerated and stopped, and the purposes of not damaging the mining vehicle and ensuring safe driving and braking are achieved. The invention has reasonable structure and convenient use, can effectively prevent the derailment of the vehicle and ensure the safe transportation; in addition, the method has the advantages of simple process, low cost, high yield and long service life.
Specifically, in the invention, one side of the car stopping section 62 facing the mining vehicle 3 is provided with a first inclined plane section 621, a second inclined plane section 622 and an arc section 623 which are sequentially connected, the position of the first inclined plane section 621 corresponds to the position of the bottom plate of the mining vehicle 3, an included angle between the first inclined plane section 621 and the second inclined plane section 622 is an obtuse angle, and the arc center angle of the arc section 623 is smaller than 90 °. In the invention, when the mining vehicle 3 runs to the line terminal of the track 2 to impact the car stopping claw 6, the bottom plate of the mining vehicle 3 is firstly contacted with the first inclined surface section 621, the car stopping section 62 is pushed to rotate around the connecting seat 5, the mining vehicle 3 is decelerated under the elastic acting force of the damping buffer spring 8, then, along with the propulsion of displacement, the bottom plate of the mining vehicle 3 is in contact transition from the first inclined surface section 621 to the second inclined surface section 622, and because the included angle between the first inclined surface section 621 and the second inclined surface section 622 is an obtuse angle, the second inclined surface section 622 accelerates the deceleration of the mining vehicle 3 under the effect of ensuring enough flexible buffering. When the speed of the mining vehicle 3 is too high and the first inclined surface section 621 and the second inclined surface section 622 are difficult to decelerate and do not achieve the parking effect, the arc section 623 can slide into the bottom of the mining vehicle 3, and the deceleration effect is always guaranteed on the premise that the mining vehicle 3 is not damaged, so that the purpose of final parking is achieved.
Preferably, the second ramp section 622 is angled from 105 to 135 degrees from horizontal. In the present invention, if the angle between the second inclined surface section 622 and the horizontal plane is too large, the buffering and deceleration effect is greatly reduced, and if the angle between the second inclined surface section 622 and the horizontal plane is too small, the included angle between the first inclined surface section 621 and the second inclined surface section 622 is too small, and the mining vehicle 3 generates an obvious impact shock during the deceleration transition process, so that the mining vehicle 3 is easily damaged.
Preferably, in order to reduce interference when the catch pawl 6 is rotated, the side wall of the catch section 62 facing away from the mining vehicle 3 is plane and is flush with the outer side of the connecting section 61.
Preferably, the bottom surface of the stopper section 62 is a flat surface, and when the shock absorbing buffer spring 8 is in the initial state, the bottom surface of the stopper section 62 is parallel to the upper surface of the fixing plate 4. This allows the floor position of the mining vehicle 3 to maintain an optimal contact position with the catch segment 62.
The above is only a specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
