Description

Technical Field

[0001] The present invention relates to the technical field of mine car deceleration control, and more specifically to a dual-material rail surface steel rail structure and a method thereof. Background Art

[0002] The ring-shaped yard is a fixed mine car transporting ore in a circular single-lane manner at the shaft entrance, connecting the shaft and external transportation in underground mining. The heavy mine car loaded with ore in the ring-shaped yard at the bottom of the shaft is lifted to the ring-shaped yard at the shaft entrance by a cage, and the empty mine car unloaded in the ring-shaped yard at the shaft entrance returns to the cage to load ore.

[0003] The circular car is used to make the mine car slide by itself. Figure 1 The A, B, C, D and E sections of the track have a certain slope according to on-site adjustment so that the mine cars can slide to each process point.

[0004] Existing problems: The mine car slides down the sloping track. Due to the acceleration, the speed of the slide becomes faster and faster, so that when it reaches each process point, the mine car hits the car blocker or the mine car waiting for the tank due to the excessive inertia force, causing the mine car to derail. There is a safety hazard. It is particularly difficult to deal with heavy vehicles derailing, which seriously restricts the production progress. Summary of the invention

[0047] The surface of the rail 2 is provided with a pressure-resistant rubber component 3, and the side of the rail 2 is provided with a connection hole 201, and a fixing bolt 202 is installed in the connection hole 201. The pressure-resistant rubber component 3 is assembled with the rail 2 through the fixing bolt 202;

[0048] The pressure-resistant rubber component 3 is composed of a base 301, a rubber block 302, and a rib plate 303. A positioning hole 304 is provided on the surface of the base 301. The fixing bolt 202 passes through the positioning hole 304 and the connecting hole 201 in sequence and is fixed to the rail 2 and the pressure-resistant rubber component 3.

[0049] A rubber block 302 is disposed on the upper surface of the base 301 , and both side ends of the rubber block 302 are chamfered at 30 degrees so that the mining car 5 can be pressed against the rubber block 302 stably. Ribs 303 are disposed at both ends and the middle of the base 301 .

[0050] The first straight segment 101 , the first direction-changing segment 102 , the second straight segment 103 , the second direction-changing segment 104 and the third straight segment 105 of the surface circular parking lot 1 all have a certain slope.

[0053] The mine car 5 loaded with ore is a heavy car, and the mine car 5 after unloading is an empty car; the process of the self-sliding process of the surface circular parking lot 1 is:

[0054] The heavy vehicle is lifted from the cage 106 to the surface wellhead; the pusher 109 on the third straight section 105 pushes the empty vehicle to push the heavy vehicle out of the cage 106, and the heavy vehicle runs along the first straight section 101 to the tipper 107; the pusher 109 on the first straight section 101 pushes the heavy vehicle into the tipper 107, and the tipper 107 drives the heavy vehicle to tip over and unload the ore; the pusher 109 on the first straight section 101 pushes the next sequence of heavy vehicles into the tipper 107 and pushes out the unloaded empty vehicle at the same time; the empty vehicle enters the first reversing section 102 and the second straight section 103 in turn and slides to the plate chain climber 108, and the plate chain climber 108 makes the empty vehicle climb the slope for height compensation and pass through the second reversing section 104 and the third straight section 105 to reach the wellhead waiting tank; the pusher 109 on the third straight section 105 pushes the empty vehicle into the cage to push out the heavy vehicle in the tank, so that the empty vehicle goes down to the well.

When the pressure-resistant rubber component 3 is fastened to the rail 2 by the fixing bolts 202, the lower bevel of the rib plate 303 cooperates with the upper bevel of the base of the rail 2 so that the upper bevel of the base of the rail 2 can reliably support the rib plate 4.

[0057] Example 2

[0058] from Figure 14-15 It can be seen that in the method of a dual-material rail surface steel rail structure of the present embodiment: a mining car 5 is carried on the steel rail 2, the steel rail 2 is regarded as a steel rail surface, the rubber block 302 is regarded as a soft material rail surface, the upper end surface of the soft material rail surface is higher than the upper end surface of the steel rail surface by a dimension a, the length dimension of the rubber block 302 is b, the width dimension of the rubber block 302 is c, and the thickness dimension of the rubber block 302 is d.

[0059] The steel rail surface and the soft material rail surface are combined to form a dual-material rail surface;

[0060] The mining car 5 slides along the inclined surface circular parking lot 1, and travels on the dual-material rail surface. The soft material rail surface is higher than the steel rail surface. The wheels are first pressed into the soft material rail surface, and the wheels press into the rubber block 302 along the driving direction, so that the pressured part of the rubber block 302 is deformed, and the rubber block generates resistance to stop the wheel, thereby effectively reducing the running speed of the wheel;

[0061] When the wheel is pressed down by an amount equal to a, the wheel reaches the steel rail surface, and the steel rail surface supports the wheel, and the soft material rail surface is no longer further compressed. The support of the steel rail surface can ensure that the mine car 5 still has enough inertia to continue to slide after deceleration.

[0062] According to the actual self-sliding speed of the mine car 5 on site, the height difference between the soft rail surface and the steel rail surface, as well as the length and hardness of the soft rail surface are adjusted to control the self-sliding speed of the mine car 5 so that the mine car can slide smoothly into the process point.

[0063] The present invention effectively controls the speed of the mine car before entering the process point, so that the mine car can enter the process point at a stable speed, avoids the occurrence of collision accidents, ensures the safe operation of the circular parking lot, and effectively improves safety protection;

[0064] The mine car 5 in the surface circular parking lot 1 slides into the dual-material track surface section by itself, effectively reducing the excessive self-sliding speed of the mine car 5. The mine car 5 can slide smoothly to each process point, avoiding the occurrence of collisions and derailment accidents, making the working environment safer, improving the production safety factor, ensuring the safe operation of the surface circular parking lot 1, and effectively improving production efficiency. It reduces the cost of manpower, time, and material resources for handling mine car derailment and equipment failures, reduces equipment failures, and makes production safer and smoother.

Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
