[0022] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0023] like Figure 1As shown, the mine transportation system 100 of the embodiment of the present invention includes a winch 1, a material cart 2 and a detection device (not shown in the figure), the winch 1 includes a driving device and a traction rope 12, the material cart 2 includes a frame 21 and wheels, the wheels are rotatably connected to the frame 21, one end of the traction rope 12 is connected to the frame 21, the detection device is connected to the frame 21 or the wheel, the detection device is used to detect the rotation speed of the wheel, and the detection device is electrically connected to the driving device.

[0024] In the mine transportation system 100 of the embodiment of the present invention, when the detection device detects that the wheel speed exceeds a preset value, the detection device can generate an abnormal electrical signal and send it to the driving device, and control the running speed of the winch 1 through the driving device, so as to control the running speed of the material vehicle 2 when the material vehicle 2 goes downhill, thereby preventing the material vehicle 2 from damaging the protective device and reducing the risk of the material vehicle 2 falling off the road, thereby improving the safety of mine transportation.

[0025] It is understandable that the mine transportation system 100 is provided with a corresponding control console so that the operator can remotely control the mine transportation system 100, and the detection device and the driving device are electrically connected through the control console; for example, the detection device sends an electrical signal to the control console, and the driving device is controlled by the control console.

[0026] Optionally, the detection device is a wheel speed sensor, and the wheel speed sensor is installed on the wheel.

[0027] The wheel speed sensor can measure the wheel speed in real time and accurately, so as to transmit the signal to the drive device in time when the wheel speed exceeds the preset value, thereby controlling the speed of the material vehicle 2.

[0028] As an example, Figure 1 As shown, the winch 1 is an endless rope winch, and the winch 1 also includes a drum 11, a traction rope 12 is wound around the drum 11, and one end is connected to the frame 21; the wheels of the material cart 2 cooperate with the track 3, and multiple material carts 2 are connected in sequence, each material cart 2 corresponds to at least one detection device, and the material cart 2 located at the end is connected to the traction rope 12; the driving device is used to control the rotation of the drum to generate traction on the frame 21 through the traction rope 12, thereby controlling the material cart 2 to travel along the track 3 in the tunnel.

[0029] like Figure 1 As shown, the downhill section of the track 3 is provided with a plurality of gate-type vehicle-blocking brakes 31 arranged along the extension direction of the track 3. The gate-type vehicle-blocking brakes 31 can block the material vehicle 2 to prevent the material vehicle 2 from sliding down the slope, so that the material vehicle 2 can stop in the downhill section.

[0030] Optionally, a front camera is provided on the front side of the material vehicle 2, and a rear camera is provided on the rear side. The front camera and the rear camera display monitoring images through a console, and the operation of the material vehicle 2 is controlled based on the monitoring images.

[0031] The road conditions can be monitored in real time through the monitoring images of the front camera and the rear camera. When the material vehicle 2 enters complex sections such as bends, forks, downhills, etc., the console sends a signal to the drive device to control the material vehicle 2 to slow down, so that the material vehicle 2 passes smoothly, thereby improving the safety of mine transportation.

[0032] In some embodiments, Figure 2 As shown, the mine transportation system 100 further includes a brake assembly 4 , which includes a brake disc 41 and a brake caliper for clamping the brake disc 41 . The brake disc 41 is connected to the wheel, and the brake caliper is connected to the vehicle frame 21 .

[0033] When the material vehicle 2 is going downhill at a fast speed, the rotation speed of the brake disc 41 can be adjusted by adjusting the clamping force of the brake caliper on the brake disc 41, and then the rotation speed of the wheel can be adjusted to achieve the deceleration and parking action of the material vehicle 2, so that the material vehicle 2 can go downhill smoothly, thereby further reducing the risk of the material vehicle 2 derailing and improving the safety of mine transportation.

[0034] As an example, Figure 1 and Figure 2 As shown, each material cart 2 is provided with four wheels, which are respectively a first wheel 22, a second wheel 23, a third wheel 24 and a fourth wheel 25. The first wheel 22 and the second wheel 23 are coaxially arranged and respectively matched with two tracks 3. The first wheel 22 and the second wheel 23 are connected by an axle 27, the third wheel 24 and the fourth wheel 25 are coaxially arranged and respectively matched with two tracks 3. The third wheel 24 and the fourth wheel 25 are also connected by the axle 27, and the axle 27 is rotatably connected to the frame 21; wherein, the first wheel 22 and the third wheel 24 correspond front to back, and the second wheel 23 and the fourth wheel 25 correspond front to back.

[0035] The brake assembly 4 corresponds to the wheel one by one and is arranged on the inner side of two coaxially arranged wheels. The brake disc 41 is disc-shaped and coaxially sleeved on the wheel axle 27. The brake disc 41 rotates synchronously with the wheel axle 27. When the brake caliper clamps the brake disc 41, the material vehicle 2 can be decelerated and stopped.

[0036] In some embodiments, Figure 3 and Figure 4 As shown, the brake caliper includes a first clamping member 42 and a second clamping member 43, which are respectively arranged on both sides of the brake disc 41 and are movably connected to the frame 21. The brake assembly 4 also includes a driving assembly 5 for driving the first clamping member 42 and the second clamping member 43 to move relative to each other.

[0037] The first clamp 42 and the second clamp 43 are controlled to be relatively close or relatively far away by the driving assembly 5, thereby adjusting the friction between the first clamp 42 and the second clamp 43 and the brake disc 41. As the friction between the first clamp 42 and the second clamp 43 and the brake disc 41 increases, the braking force of the brake assembly 4 on the material vehicle 2 gradually increases, so that the speed of the material vehicle 2 gradually decreases, thereby maintaining the smooth transportation of the material vehicle 2 during the downhill process of the material vehicle 2, and improving the safety of mine transportation. When the friction between the first clamp 42 and the second clamp 43 and the brake disc 41 increases to a certain value, the material vehicle 2 stops.

[0038] Optionally, friction pads are provided on the sides of the first clamping member 42 and the second clamping member 43 that are close to each other.

[0039] Thereby, the friction between the brake caliper and the brake disc 41 can be increased to achieve a rapid deceleration effect, thereby causing the material vehicle 2 to decelerate or stop quickly and improving the deceleration efficiency.

[0040] As an example, Figure 4 and Figure 5 As shown, the first clamping member 42 and the second clamping member 43 are both rectangular in shape, and are respectively arranged on both sides of the brake disc 41 along the axial direction of the wheel axle 27; the upper side surface of the first clamping member 42 is connected to the first slider 421, and the upper side surface of the second clamping member 43 is connected to the second slider 431, and the lower side of the frame 21 is connected to the connecting frame 26, and the lower side surface of the connecting frame 26 has a slide groove 261, and the first slider 421 and the second slider 431 are both slidably matched with the slide groove 261, so as to realize the connection between the first clamping member 42 and the second clamping member 43 and the frame 21, and the first clamping member 42 and the second clamping member 43 can be arranged to slide along the axial direction of the wheel axle 27.

[0041] In some embodiments, Figure 4 As shown, the driving assembly 5 includes a first driving member 51, a first connecting rod 52, a second driving member 53 and a second connecting rod 54. The first driving member 51 is rotatably connected to the frame 21, one end of the first connecting rod 52 is hinged to the first driving member 51, and the other end is hinged to the first clamping member 42, so that the first driving member 51 is rotated to drive the first clamping member 42 to move; the second driving member 53 is rotatably connected to the frame 21, one end of the second connecting rod 54 is hinged to the second driving member 53, and the other end is hinged to the second clamping member 43, so that the second driving member 53 is rotated to drive the second clamping member 43 to move.

[0042] Through the above arrangement, the first driving member 51, the first connecting rod 52 and the first clamping member 42 form a crank slider mechanism, and when the first driving member 51 rotates, the first clamping member 42 can be driven to slide; similarly, the second driving member 53, the second connecting rod 54 and the second clamping member 43 also form a crank slider mechanism, and when the second driving member 53 rotates, the second clamping member 43 can be driven to slide; thus, by controlling the first driving member 51 and the second driving member 53 to rotate in opposite directions, the first clamping member 42 and the second clamping member 43 can be controlled to be relatively close to or relatively far away from each other.

[0043] Optionally, when the drive assembly 5 in the embodiment of the present invention is working, the first drive member 51 and the second drive member 53 do not need to rotate 360 ​​degrees. The first drive member 51 and the second drive member 53 can both rotate back and forth within a certain angle range to clamp or release the brake disc 41, thereby reducing the range of movement of the first drive member 51 and the second drive member 53 and reducing the installation space of the drive assembly 5 to facilitate the installation of the drive assembly 5.

[0044] In some embodiments, a linkage assembly 6 is provided between the first driving member 51 and the second driving member 53 , and the first driving member 51 and the second driving member 53 are connected via the linkage assembly 6 so that the first driving member 51 and the second driving member 53 rotate in opposite directions.

[0045] By providing the linkage assembly 6 , the synchronous rotation of the first driving member 51 and the second driving member 53 can be achieved, so that the control of the first driving member 51 and the second driving member 53 is simpler.

[0046] In some embodiments, Figure 3 As shown, the linkage assembly 6 includes a first gear 61 and a second gear 62, the first gear 61 is connected to the first driving member 51, the second gear 62 is connected to the second driving member 53, and the first gear 61 and the second gear 62 are meshed; or, a plurality of linkage gears 63 are provided between the first gear 61 and the second gear 62, the number of the linkage gears 63 is an even number, and the first gear 61 and the second gear 62 are connected through the linkage gears 63.

[0047] Through the above arrangement, when the first gear 61 and the second gear 62 are meshed, the rotation directions of the first gear 61 and the second gear 62 are opposite; when the first gear 61 and the second gear 62 are transmitted through the interlocking gear 63, the number of the interlocking gears 63 is an even number, and the rotation directions of the first gear 61 and the second gear 62 are still opposite; thereby, the rotation directions of the first driving member 51 and the second driving member 53 can be kept opposite.

[0048] Alternatively, if Figure 3As shown, the first gear 61 and the first driving member 51 are connected through the first driving shaft 55, the second gear 62 and the second driving member 53 are connected through the second driving shaft 56, and the first driving shaft 55 and the second driving shaft 56 are both rotatably connected to the connecting frame 26 through a support, so that stable installation of the linkage assembly 6 can be achieved.

[0049] In some embodiments, Figure 5 As shown, the mine transportation system 100 also includes a power member 64, which is connected to the frame 21; when the first gear 61 is meshed with the second gear 62, the power member 64 is used to drive the first gear 61 or the second gear 62 to rotate; when the first gear 61 and the second gear 62 are connected through the connecting gear 63, the power member 64 is used to drive the connecting gear 63 to rotate.

[0050] The power member 64 is more conducive to controlling the rotation of the first driving member 51 and the second driving member 53, and further controlling the relative movement of the first clamping member 42 and the second clamping member 43.

[0051] Optionally, the power member 64 is electrically connected to a control console of the mine transportation system 100 .

[0052] Alternatively, if Figure 5 As shown, the power member 64 is a motor, which is connected to the connecting frame 26 through a support, and the motor output shaft is connected to one of the linkage gears 63.

[0053] Thus, the motor can drive the connecting gear 63 to rotate, and the connecting gear 63 drives the first gear 61 and the second gear 62 to rotate synchronously, and then drives the first clamping member 42 and the second clamping member 43 to move relative to each other through the first driving member 51 and the second driving member 53 to achieve clamping or loosening of the brake disc 41.

[0054] As an example, Figure 5 As shown, Figure 3 and Figure 5 As shown, two interlocking gears 63 are arranged between the first gear 61 and the second gear 62, and a support is fixedly connected to the lower side of the connecting frame 26, and the two interlocking gears 63 are rotatably connected to the support, thereby realizing the connection between the interlocking gears 63 and the frame 21. A power member 64 is installed on the support, and the output shaft of the power member 64 is connected to one of the interlocking gears 63, which can control the interlocking gear 63 to rotate forward, reverse and stop.

[0055] In some embodiments, the power member 64 is electrically connected to the detection device.

[0056] By electrically connecting the power member 64 with the detection device, when the detection device detects that the wheel speed exceeds the preset value, the detection device can simultaneously send an abnormal electrical signal to the driving device and the power member 64. On the one hand, the driving device controls the running speed of the winch 1 to reduce the speed of the material vehicle 2; on the other hand, the power member 64 controls the rotation of the first gear 61 and the second gear 62, and then drives the first clamping member 42 and the second clamping member 43 to be relatively close through the first driving member 51 and the second driving member 53. The first clamping member 42 and the second clamping member 43 are clamped on the brake disc 41, and the friction between the first clamping member 42 and the second clamping member 43 and the brake disc 41 can achieve deceleration of the material vehicle 2.

[0057] Therefore, the above two aspects can achieve the deceleration of the material vehicle 2, so that the material vehicle 2 can run smoothly in complex road conditions such as downhill and turning, thereby improving the safety of mine transportation.

[0058] In some embodiments, Figure 3 As shown, the brake assemblies 4 correspond one-to-one to the wheels. The brake assembly 4 corresponding to the first wheel 22 is the first brake assembly, and the brake assembly 4 corresponding to the second wheel 23 is the second brake assembly. The first driving member 51 of the first brake assembly and the first driving member 51 of the second brake assembly are both connected to the first driving shaft 55, and the two first driving shafts 55 are transmission connected.

[0059] By connecting the two first drive shafts 55 in transmission, the first brake assembly and the second brake assembly can be operated synchronously. The first brake assembly and the second brake assembly are braked simultaneously from positions close to the first wheel 22 and the second wheel 23 respectively. The first wheel 22 and the second wheel 23 are subjected to uniform force, so that the material vehicle 2 maintains good stability, thereby further improving the stability of the mine material vehicle 2 during the downhill process.

[0060] In some embodiments, Figure 3 As shown, a transmission assembly 7 is provided between the first driving member 51 and the second driving member 53. The transmission assembly 7 includes a transmission shaft 71 and a bevel gear pair 72. The transmission shaft 71 is rotatably connected to the frame 21. There are two bevel gear pairs 72. Both ends of the transmission shaft 71 are connected to the two first driving shafts 55 through two bevel gear pairs 72 respectively.

[0061] The first driving member 51 and the second driving member 53 are connected by two bevel gear pairs 72, which has the characteristics of high transmission efficiency, strong bearing capacity and small space occupation.

[0062] As an example, Figure 2 and Figure 3As shown, the transmission shaft 71 is rotatably connected to the frame 21 through a support, and the bevel gear pair 72 includes two bevel gears meshing with each other. The two bevel gears are respectively sleeved on the transmission shaft 71 and the first drive shaft 55. The bevel gear sleeved on the first drive shaft 55 rotates synchronously with the first drive shaft 55, and the bevel gear sleeved on the transmission shaft 71 rotates synchronously with the transmission shaft 71; the two bevel gear pairs 72 are respectively arranged on both sides of the transmission shaft 71, thereby realizing the transmission of the two first drive shafts 55.

[0063] like Figure 3 As shown, the two brake discs 41 corresponding to the first wheel 22 and the third wheel 24 correspond front to back, and the two first driving members 51 on one side of the two corresponding brake discs 41 are connected to the same first driving shaft 55, and the first gear 61 is sleeved on the first driving shaft 55 and rotates synchronously with the first driving shaft 55; the two second driving members 53 on the other side of the two corresponding brake discs 41 are connected to the same second driving shaft 56, and the second gear 62 is sleeved on the second driving shaft 56 and rotates synchronously with the second driving shaft 56.

[0064] Thereby, the four brake assemblies 4 can be operated synchronously, thereby achieving the deceleration of the front and rear wheels at the same time, so that the four wheels are evenly stressed, thereby improving the stability of the deceleration process of the material vehicle 2, thereby improving the stability of the material vehicle 2 during the downhill process.

[0065] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments by those of ordinary skill in the art are all within the scope of protection of the present invention.
