[0033] like Figure 3 As shown, the first crawler mobile platform 101 of this embodiment includes a driving station support platform 1011, a first track 1012 installed on the upper side of the driving station support platform 1011, a first crawler driving device 1013 installed on the lower side of the driving station support platform 1011, a first lifting member 1015 installed at the bottom diagonal of the driving station support platform 1011, and a first support seat 1014 installed at the output end below the first lifting member 1015. The driving station support platform 1011 is provided with docking holes on both sides, and the first track 1012 is provided on both sides. Two driving devices 102 are symmetrically arranged, and the two driving devices 102 are correspondingly connected with a hydraulic tensioning device 103, wherein the first lifting member 1015 drives the first support seat 1014 to be raised and lowered. On the one hand, the first support seat 1014 can be in better contact with the ground when assembling the track, thereby ensuring the stability of the first crawler mobile platform 101 during operation; on the other hand, the first support seat 1014 can be lifted up during transportation, so as to facilitate the first crawler driving device 1013 to drive the driving station support platform 1011 to be transported and moved.

[0034] like Figure 2 As shown, the driving device 102 of this embodiment includes a support frame 1021 that is slidably matched on the upper side of the driving station support platform 1011, a motor 1022 installed on the upper side of the support frame 1021, and a driving wheel 1023 installed on the output end below the motor 1022; the hydraulic tensioning device 103 includes two slide rails 1031 installed on the upper side of the driving station support platform 1011, a slider 1032 that is slidably matched on the two slide rails 1031 and fixedly connected to the bottom of the support frame 1021, and a hydraulic telescopic push rod 1033 installed on the upper side of the driving station support platform 1011 and fixedly connected to the support frame 1021 at the output end; the material transport vehicle 3 includes a plurality of carriage bodies 301 that are connected in sequence and correspond to the first rail 1012 and the second rail 203, and a driving plate 302 that is installed on both sides of the plurality of carriage bodies 301 and corresponds to the driving wheel 1023.

[0035] The motor 1022 provides power to the driving wheel 1023, and the driving wheel 1023 rubs the driving plates 302 on both sides of the material transport vehicle 3 to provide power to the material transport vehicle 3. The electro-hydraulic telescopic push rod 1033 of the hydraulic tensioning device 103 is connected to the support frame 1021, which can drive the support frame 1021 and the motor 1022 and driving wheel 1023 installed on the support frame 1021 to move back and forth through the relative movement of the slider 1032 on the slide rail 1031, so that the motor 1022 keeps in contact with the driving plate 302 of the car body 301 and has a certain clamping force. At the same time, the hydraulic tensioning device 103 adjusts the clamping force between the driving wheel 1023 and the driving plate 302 by adjusting the output force.

[0036] like Figure 4 As shown, the mobile folding track station 2 of this embodiment includes a second crawler mobile platform 201, a plurality of track support frames 202 installed on the upper side of the second crawler mobile platform 201 and foldably connected, and a second track 203 respectively installed on the upper side of the plurality of track support frames 202 and corresponding to the first track 1012. A supporting telescopic component 4 is installed between the plurality of track support frames 202. Both ends of the track support frames 202 are provided with docking interfaces. When the plurality of track support frames 202 are unfolded, the docking interfaces of adjacent track support frames 202 are docked, and the docking holes can be manually connected with plug rods to improve the stability of the dynamic track formed by the second track 203 after unfolding.

[0037] like Figure 3-Figure 6As shown, in this embodiment, the second crawler mobile platform 201 includes a track support platform 2011, a second crawler drive device 2012 installed on the lower side of the track support platform 2011, the track support frame 202 includes a fixed track support frame 2021 and a plurality of movable track support frames 2022, the fixed track support frame 2021 is installed on the track support platform 2011, the support telescopic assembly 4 includes a rotating connection member 401 installed between two adjacent track support frames 202 and at least one group of hydraulic rods 402, the hydraulic rods 402 between the two ends of the fixed track support frame 2021 and the adjacent movable track support frames 2022 are arranged at the sides of the two, the fixed end of the hydraulic rod 402 at the connection between the two movable track support frames 2022 is arranged at the rotating connection member 401, and the telescopic end of the hydraulic rod 402 is arranged on the movable track support frame 2022.

[0038] The fixed ends of the hydraulic rod 402 between the two ends of the fixed track support frame 2021 and the adjacent movable track support frame 2022 are arranged on the side of the fixed track support frame 2021, and the telescopic ends are arranged on the side of the movable track support frame 2022 at the corresponding end. In this embodiment, the rotating connecting member 401 can be a hinge in the prior art.

[0039] Multiple track support frames 202 are connected by rotating connectors 401 and hydraulic rods 402, driving multiple movable track support frames 2022 to extend and retract toward the fixed track support frame 2021 through the rotating connectors 401. The number of movable track support frames 2022 on both sides of the fixed track support frame 2021 is generally set to be consistent, and can be spliced ​​and extended as needed. The track layout can be flexibly adjusted according to mining needs, which can significantly improve transportation efficiency.

[0040] The second crawler mobile platform 201 of the present embodiment includes a track support platform 2011, a second crawler drive device 2012 installed on the lower side of the track support platform 2011, a second lifting member 2013 installed at the diagonal lower side of the track support platform 2011, and a second support seat 2014 installed at the output end below the second lifting member 2013, wherein the second lifting member 2013 drives the second support seat 2014 to be lifted and lowered, and its action on the first lifting member 1015 is consistent. On the one hand, it can adapt to the ups and downs of the ground. When installed on the dynamic track line, the second support seat 2014 can be better contacted with the ground to ensure that the material transport vehicle 3 runs stably and reliably on the dynamic track line. On the other hand, during transfer, the second support seat 2014 can be lifted to facilitate the second crawler drive device 2012 to move horizontally on the ground.

[0041] The first lifting member 1015 at the bottom of the driving station support platform 1011 and the second lifting member 2013 under the track support platform 2011 have the same structural setting, and can adopt an electric telescopic rod or a bolt and nut mechanical lifting mechanism. The electric telescopic rod or the bolt and nut mechanical lifting mechanism are both existing conventional lifting mechanism forms, and their principles will not be repeated here.

[0042] When mining operations are being carried out, there will generally be scenes where it is necessary to go deeper and change the transportation direction. At this time, the dynamic rail transportation system of the present invention will come into play. When it is necessary to change the position or direction, the first lifting member 1015 and the second lifting member 2013 of the first crawler mobile platform 101 and the second crawler mobile platform 201 drive the first support seat 1014 and the second support seat 2014 to rise off the ground, and the first crawler drive device 1013 and the second crawler drive device 2012 carry the first crawler mobile platform 101 and the second crawler mobile platform 201 to change the position or direction. When transferring to the target position, the multiple foldable and movable track support frames 202 are unfolded by the hydraulic rod 402, and the movable track support frames 2022 are unfolded along both sides of the fixed track support frames 2021 to connect the second track 203. The unfolded track support frames 202 are flush with the drive station support platform 1011, and the first track 1012 and the second track 203 are connected. The docking holes at the junction of the drive station support platform 1011 and the track support frames 202, as well as the docking holes between adjacent track support frames 202 are manually fastened by inserting rods to ensure the stability of the track.

[0043] The width and height of the tunnel for transferring materials in mines are limited. Since the mobile drive station 1 needs to set two sets of drive devices 102 on the first track 1012 to drive the material transport vehicle 3, the width of the drive station support platform 1011 along the direction perpendicular to the dynamic track line is wider than the width of the active track line. The track shoe direction of its first crawler drive device 1013 is arranged below the drive station support platform 1011 along this direction. When transfer is required, the first crawler drive device 1013 drives the drive station support platform 1011 to rotate 90 degrees, and rotates the drive station support platform 1011 on the wider side along the direction of the tunnel track line, thereby making it easier for the mobile drive station 1 to transfer in the tunnel.

[0044] The first track 1012 of the mobile driving station 1 is a fixed track of an inclined street.

[0045] In practical applications, a mobile drive station 1 can be connected to a mobile folding track station 2 to form a short-line dynamic track line, or multiple mobile drive stations 1 and mobile folding track stations 2 can be connected to form a long-distance dynamic track line. According to actual needs, modular combination and assembly can be performed.

[0046] like Figure 2 , 5 As shown, the first crawler drive device 1013 and the second crawler drive device 2012 of this embodiment both include track shoes, driving wheels, induction wheels and front and rear road wheels, which drive the mobile drive station 1 and the mobile folding track station 2 to move, thereby realizing the transfer and docking of dynamic tracks.

[0047] A mine rail transport line includes a transport track, the transport track includes the above-mentioned dynamic track line, the transport track and the dynamic track line form a rail transport line, and the transport track is a fixed mine transport track. The dynamic track line composed of a mobile drive station 1 and a mobile folding track station 2 can be flexibly connected to the fixed transport track for track extension application.

[0048] The present invention is not limited to the above-mentioned embodiments. Anyone should be aware that any structural changes made under the enlightenment of the present invention, and any technical solutions that are the same or similar to the present invention, fall within the protection scope of the present invention.
