DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] After mining, the ore inside the mine needs to be transported to the ground by mine cars. Compared with trackless mine cars, rail mine cars can move along a predetermined track and can realize large-scale ore transportation.

[0023] However, due to the type of ore and the structure of the surrounding rocks, some mines have small tunnel sizes and can only lay one set of tracks. During the ore transportation process, only one set of mine cars can move one-way on the track, affecting the efficiency of mine ore transportation.

[0024] In order to solve the above problems, refer to the attached Figure 1 -Attached Figure 5 A mine roadway right distribution device, the mine roadway includes an ascending channel 200 and a descending channel 300, an avoidance chamber 100 is arranged between the ascending channel 200 and the descending channel 300, an ascending track 220 is installed in the ascending channel 200, and a descending track 320 is installed in the descending channel 300, and an avoidance device connecting the ascending track 220 and the descending track 320 is installed in the avoidance chamber 100. By setting the avoidance device, two groups of relatively moving rail mine cars can be accommodated, so that the relatively moving rail mine cars can pass through the avoidance chamber 100 in turn, and the rail mine cars are controlled to avoid each other in the avoidance chamber 100, so that the mine cars moving in opposite directions can move in an orderly manner in the mine, which greatly improves the efficiency of mine car transportation.

[0025] Specifically, the avoidance device includes a first avoidance track 500 and a second avoidance track 600 arranged in parallel, and a track changing device 700 is installed at the connection between the first avoidance track 500 and the second avoidance track 600 and the ascending track 220 and the descending track 320. The track changing device 700 is used to control the rail mine car to move through the first avoidance track 500 or the second avoidance track 600; the track changing device 700 is controlled to be in a first posture, which can guide the rail mine car to the surface of the first avoidance track 500, and the track changing device 700 is controlled to be in a second posture, which can guide the rail mine car to the surface of the second avoidance track 600; when the mine cars moving towards each other meet in the avoidance chamber 100, one group of mine cars is controlled to move to the surface of the second avoidance track 600, and can be staggered from the ascending track 220 and the first avoidance track 500, to ensure that the other group of mine cars can normally pass through the first avoidance track 500 for continuous transportation.

[0026] An indication device 400 is also installed in the avoidance chamber 100. The indication device 400 sends indication signals in the direction of the ascending track 220 and the descending track 320. The rail-mounted mine car chooses to move or stop according to the indication signals. By setting the indication device 400, indication signals can be sent to the mine cars in the ascending channel 200 and the descending channel 300, and the rail-mounted mine cars in the ascending channel 200 and the descending channel 300 can be directed to move according to a predetermined trajectory, and the two groups of rail-mounted mine cars can be controlled to pass through the avoidance chamber 100 in an orderly manner to avoid the occurrence of safety accidents.

[0027] In summary, through the above-mentioned structural design, the spatial volume in the avoidance chamber 100 can be effectively utilized, and only one set of tracks is still arranged in the ascending channel 200 and the descending channel 300. The first avoidance track 500 and the second avoidance track 600 arranged in parallel in the avoidance chamber 100 can control the two groups of mine cars moving in opposite directions to avoid each other, and move safely and orderly in the mine tunnels, greatly improving the efficiency of mine transportation.

[0028] A first detection device 210 is installed on the inner wall of the ascending channel 200, and a second detection device 310 is installed on the inner wall of the descending channel 300. The first detection device 210 and the second detection device 310 are used to detect the expected time for the rail mine car to arrive at the avoidance chamber 100, that is, to determine which group of the two groups of rail mine cars arrives at the avoidance chamber 100 first. The first detection device 210 and the second detection device 310 are electrically connected to the indication device 400 for adjusting the indication signal.

[0029] For example, when the descending rail mine car in the ascending channel 200 reaches the avoidance chamber 100 earlier than the ascending rail mine car in the descending channel 300, an indication signal is sent to the indication device 400 through the first detection device 210 and the second detection device 310, commanding the descending rail mine car in the ascending channel 200 to move normally to the surface of the second avoidance track 600 in the avoidance chamber 100, and an indication signal is sent to the ascending rail mine car in the descending channel 300, commanding the rail mine car in the descending channel 300 to slow down or stop; until the descending rail mine car is completely offset from the first avoidance track 500, the descending channel 300 is directed to move upward, pass through the first avoidance track 500, enter the ascending channel 200, and offset from the descending rail mine car; after the ascending rail mine car moves and offsets, the descending rail mine car in the second avoidance track 600 is controlled to move to the descending channel 300.

[0030] Through the above-mentioned structural design, it is possible to realize automatic detection of the movement of the mine car, automatically judge the remaining time for the mine car to reach the avoidance chamber 100, and realize automatic adjustment and control; the first detection device 210 and the second detection device 310 here can be selected as existing speed sensors, and the speed sensor is used to judge the movement rate of the mine car. When the remaining distance is fixed, the expected time for the mine car to reach the avoidance chamber 100 can be accurately determined.

[0031] Specifically, the indicating device 400 includes an indicating terminal 410, and the indicating terminal 410 includes a prohibiting light source 411 and a passing light source 412 arranged in parallel. The prohibiting light source 411 and the passing light source 412 are selected as signals with different light sensations, which can send different signals toward the descending channel 300 and the ascending channel 200 to realize command and control.

[0032] The prohibiting light source 411 and the passing light source 412 here can be designed with reference to traffic lights, and the prohibiting light source 411 is set to emit a red or yellow light source, and the passing light source 412 is controlled to emit a green light source.

[0033] Furthermore, the prohibiting light source 411 and the passing light source 412 are both projection light sources, and a shielding device 440 is installed on the outer side of the indicating end 410. The shielding device 440 is located on the side close to the ascending channel 200 and the descending channel 300. By setting the prohibiting light source 411 and the passing light source 412 as projection light sources, the range of receiving command signals in the ascending channel 200 and the descending channel 300 can be increased, and its conspicuousness can be improved to ensure that the rail mine car receives it in time; by setting the shielding device 440, it can be located in the middle position to divide the prohibiting light source 411 and the passing light source 412, so as to avoid different types of light sources from influencing each other and affecting the judgment of the rail mine car driver.

[0034] Please refer to the attached Figure 5The indicating device 400 also includes a positioning rod 430, the lower end of the positioning rod 430 is electrically rotatably connected to the mounting platform 420, and two groups of indicating terminals 410 are installed at the lower end of the mounting platform 420. The shielding device 440 is located on the moving path of the indicating terminal 410, and a cleaning device is installed inside the shielding device 440. The positioning rod 430 here can be installed at a position that avoids the top of the inner wall of the chamber 100. The mounting platform 420 here is internally installed with an electric rotating element, which can control the directional rotation of the mounting platform 420 relative to the positioning rod 430. In the process of controlling the directional rotation of the mounting platform 420, the position of the prohibition light source 411 and the passing light source 412 can be switched to realize the switching of the indication signal.

[0035] In addition, the surface of the indicating terminal 410 can be cleaned by a cleaning device, and can adapt to the high humidity and dusty environment underground. During the rotation of the mounting platform 420, the signal can be switched and the surface of the indicating terminal 410 can be automatically cleaned, thereby ensuring the stability and effectiveness of the light source and reducing the work efficiency of the staff.

[0036] It should be noted that the two groups of indicator terminals 410 are as follows: Figure 5 As shown, they are arranged alternately; by rotating the mounting platform 420, the light source 411 can be controlled to be prohibited, or the light source 412 can be located on the left or right side, and different signals can be sent into the ascending channel 200 or the descending channel 300 to adaptively command and control the railcars in the ascending channel 200 or the descending channel 300.

[0037] Two groups of first conductive ends 421 electrically connected to the indicating ends 410 are installed on the upper end of the mounting platform 420, and a second conductive end 431 is fixed to the outer wall of the positioning rod 430. The second conductive end 431 is arc-shaped and is located near the ascending channel 200 and the descending channel 300. When the first conductive end 421 and the second conductive end 431 are in contact, the two are controlled to be in a conductive state, and the conductive prohibiting light source 411 and the through light source 412 on the second conductive end 431 side can be controlled to be in a conductive state to realize signal control; when the corresponding prohibiting light source 411 or the through light source 412 rotates to a side away from the second conductive end 431, the corresponding prohibiting light source 411 or the through light source 412 is controlled to be in a power-off state; the above-mentioned mechanical structure can realize adaptive automatic control, realize automatic on-off control, and improve control efficiency.

[0038] A third detection device 610 electrically connected to the indicator device 400 and the track changing device 700 is installed on the outside of the second avoidance track 600. The third detection device 610 can detect whether the rail mine car has completely entered the second avoidance track 600. When the rail mine car has completely entered the second avoidance track 600, the control indicator device 400 changes the signal to control the outer rail mine car to move through the first avoidance track 500.

[0039] A fourth detection device electrically connected to the indicator device 400 and the track changing device 700 is installed on the outer side of the first avoidance track 500. By setting the fourth detection device, it can be detected whether the rail mine car moves through the first avoidance track 500. When the rail mine car completely moves away from the surface of the first avoidance track 500, the signal of the indicator device 400 is adjusted while adjusting the guiding posture of the track changing device 700 to control the mine car on the surface of the second avoidance track 600 to move normally in the tunnel.

[0040] Please refer to the attached Figure 4 Specifically, the track-changing device 700 includes a guide assembly 720 located on the inner side and a track-changing assembly 710 located on the outer side. The track-changing assembly 710 is electrically controlled to move away from or close to the second avoidance track 600. By controlling the track-changing assembly 710 to be located on the side close to the ascending track 220, the wheelset at the lower end of the rail-mounted mine car can be guided, and the rail-mounted mine car can be controlled to move to the surface of the first avoidance track 500, so as to realize continuous movement between the ascending track 220 and the descending track 320; the track-changing assembly 710 is controlled to be located on the side away from the ascending track 220. At this time, the track-changing assembly 710 will not guide the wheelset, and the mine car can move from the ascending track 220 to the surface of the second avoidance track 600, and the mine car can move to the surface of the second avoidance track 600 for avoidance.

[0041] Through the structural design of the first avoidance track 500, the second avoidance track 600 and the track changing device 700, two groups of mine cars moving towards each other can avoid each other in an orderly and safe manner in the avoidance chamber 100, realizing the efficient allocation of road rights in mine tunnels. At the same time, through the above-mentioned structural design, the rail mine car entering the second avoidance track 600 does not need to return, and it can complete continuous transportation by continuing to move forward, which greatly improves the efficiency of mine transportation.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
