[0032] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0033] Mine cars, as the main means of transportation in mines, play an indispensable role. However, after the mine cars have completed material transportation, how to unload the materials efficiently and safely has become a major challenge facing the industry.

[0034] like Figure 1 As shown, the present invention provides a unloading mine car, comprising:

[0035] The crawler chassis assembly 1 parallel to the ground is the core foundation of the entire mine car and carries the mine car body and other parts. In the embodiment of the present invention, the crawler chassis assembly 1 is made of high-strength material, has good wear resistance and impact resistance, and can travel stably in complex terrain.

[0036] The mine car body 2 is fixedly connected to the crawler chassis assembly 1, and the mine car body 2 adopts a lightweight design to ensure that the overall driving performance is not affected while the load-bearing capacity is improved.

[0037] The gripper bracket 3 is connected to the mine car body 2 and can be raised and lowered as needed to facilitate the grabbing and unloading of materials.

[0038] The unloading assembly 4 is detachably connected to the gripper bracket 3, and the unloading assembly 4 can conveniently unload the materials after grabbing them.

[0039] The drive assembly 5 is fixedly connected to the crawler chassis assembly 1, and the input end of the drive assembly 5 is communicatively connected to the output end of the communication module. In one embodiment of the present invention, the drive assembly 5 uses a motor and transmission technology to provide power output for the mining vehicle to drive the crawler chassis assembly 1 to operate.

[0040] The control module is communicatively connected to the input end of the driving component 5 , and the control module controls the driving direction of the mining vehicle by communicating with the driving component 5 .

[0041] In some embodiments, Figure 2 As shown, the crawler chassis assembly 1 includes: a driving gear 6, a driven gear 7, a crawler 8 and a first connecting member 9. The first connecting member 9 is provided with a transition gear 10 on one side close to the ground in the vertical direction. The gear teeth of the transition gear 10 are consistent with the size of the driving gear 6 and the driven gear 7, that is, the transition gear 10 is meshed with the driving gear 6 and the driven gear 7. The gear teeth of the three are adapted to the size of the through hole 31 provided on the crawler 8. The transition gear 10 is used to fix the position of the crawler 8 to prevent the crawler 8 from deviating from the original running direction. The design of the transition gear 10 fully considers the mechanical principle, so that the meshing between the gears is more stable. One end of the first connecting member 9 in the horizontal direction is rotatably connected to the axis of the driving gear 6, so that the first connecting member 9 and the driving gear 6 can work together to realize the transmission of power in the horizontal direction. The first connecting member 9 is fixedly connected to the driving gear 6 at the rotation connection. The driving assembly 5 is used to provide a stable driving force during the operation of the equipment to ensure the good performance of the equipment under various working conditions. The first connecting member 9 is rotatably connected to the axis of the driven gear 7 at one end away from the driving gear 6 in the horizontal direction. The driven gear 7 works in coordination with the driving gear 6, so that the device has better movement performance in the horizontal direction.

[0042] like Figure 6 As shown, the crawler 8 includes a crawler shoe 29 and a crawler pin 30. Two adjacent crawler shoes 29 are movably connected via the crawler pin 30. This design enables the crawler 8 to move flexibly under various terrain conditions. The crawler shoe 29 is provided with through holes 31 corresponding to the gear teeth of the driving gear 6 and the driven gear 7, so that good meshing between the crawler 8 and the driving gear 6 and the driven gear 7 can be ensured. A protrusion 33 is provided on the side of the crawler shoe 29 away from the first connecting member 9. By providing the protrusion 33, the bite force between the mine car and the ground can be increased, making the mine car travel more stable.

[0043] In a specific implementation, the driving assembly 5 includes: a motor and its accessories, such as bolts for fixing the motor to the connecting piece, and an accessory gear matched with the driving gear 6. The accessory gear is fixedly connected to the output end of the motor, and the motor rotates to drive the accessory gear to rotate, thereby driving the driving gear 6 to rotate, and then driving the mine car to travel. The motor can rotate forward and reverse, thereby controlling the mine car to move forward and backward, etc. The motor can be a J series motor, or a motor of other series.

[0044] In some embodiments, Figure 3 As shown, the mining car body 2 includes: a base 11 fixedly connected to the first connecting member 9, a communication box 12, an oppositely arranged cable drum fixing frame 13 and a liftable component 14 are fixedly arranged on the side of the base 11 away from the crawler chassis component 1; the control module is arranged inside the communication box 12, the cable drum 15 is clamped in the middle of the cable drum 15 fixing frame 13, and a gripper bracket 3 is fixed on the end of the liftable component 14 away from the base 11.

[0045] In a specific implementation, in the crawler chassis assembly 1 described in the present invention, the base 11 is tightly fixed together with the first connecting member 9, and forms a closed loop for the crawler 8 to pass through. On the side of the base 11 facing away from the crawler chassis assembly 1, a communication box 12, an oppositely arranged cable drum fixing frame 13 and a liftable assembly 14 are fixedly arranged. The communication box 12 includes: a communication module, a control module, a gravity block and a power supply. The gravity block is at the bottom of the communication box and is used to balance the mine car. The communication module is responsible for receiving and sending various information and communicating with the control module. The power supply is used to provide power to various parts of the mine car, and the power supply can be a lithium battery or other types of batteries. The control module can use a control chip such as PLC, STM32, etc. to control the communication module to send a signal, thereby realizing the rotation of the control motor, drive assembly, electric motor and other parts.

[0046] In the specific implementation, the communication box 12 is moderately sized, which is convenient for operators to check and maintain at any time. The communication box 12 is located on the side of the base 11 away from the crawler chassis assembly 1, which does not affect the overall appearance and can effectively avoid damage during driving.

[0047] In specific implementation, the cable drum 15 can be clamped in the middle of the fixing frame 13, which is convenient for operators to take and put cables. This design not only saves space, but also greatly improves work efficiency. On the other side of the base 11, a lifting component 14 is set, which can be raised or lowered when needed, increasing the adaptability and flexibility of the equipment.

[0048] In specific implementation, Figure 8As shown, the liftable assembly 14 includes a first column 34 and a second column 35. The first column 34 is a hollow tube. The second column 35 is sleeved inside the first column 34, and the second column 35 can rotate inside the first column 34. The second column 35 of the liftable assembly 14 is away from the end of the base 11, and the gripper bracket 3 is cleverly fixed. The second column 35 drives the gripper bracket 3 to rotate by rotating. The design of the gripper bracket 3 fully considers the principle of mechanics. In the process of lifting or lowering, it can stably support various weights, ensuring the safety and stability of the mine car.

[0049] In some embodiments, Figure 4 As shown, the gripper bracket 3 includes: a first support member 16 and a second support member 17 , both of which are located on the same side of the liftable component 14 away from the base 11 , for providing support for the cable 20 and the electric motor 18 .

[0050] In specific implementation, Figure 7 As shown, a motor is fixedly installed in the second column 35 of the liftable component 14, and the output end of the motor is fixedly connected to the first gear 32 to convert electrical energy into mechanical energy. The first support member 16 and the second support member 17 are close to one end of the liftable component 14, and are provided with gear teeth meshing with the first gear 32, thereby enhancing the transmission stability between the first support member 16 and the second support member 17 and the first gear 32, ensuring that the second support member 17 can operate stably and reliably during the lifting process. After the first support member 16 and the second support member 17 are virtually extended, the angle between the two is greater than 90 degrees.

[0051] In a specific implementation, an electric motor 18 is fixed to one end of the first support member 16 away from the liftable assembly 14. The input end of the electric motor 18 is communicatively connected to the output end of the control module, so that the mine car can be remotely controlled, which improves the convenience of operation. The output end of the electric motor 18 is fixedly connected to the cable drum 15, which is responsible for retracting and releasing the cable 20.

[0052] Furthermore, the cable 20 can be connected to the cable drum 15 in such a way that one end of the cable 20 bypasses the electric motor 18 and is fixed to the column in the middle of the cable drum 15, or in such a way that one end of the cable 20 bypasses the electric motor 18 and is fixed to the circular railings on both sides of the cable drum 15.

[0053] In a specific implementation, one end of the second support member 17 away from the lifting component 14 is fixedly connected to the fixed pulley 19, and one end of the cable 20 away from the electric motor is fixedly connected to the unloading component 4 via the fixed pulley 19. The central axis of the first gear 32 is fixedly connected to the output end of the motor fixed inside the second column. The first gear 32 is meshed with the gear teeth of the first support member 16 and the second support member 17, and is used to control the position of the first support member 16 and the second support member 17 in a direction perpendicular to the ground.

[0054] In some embodiments, Figure 4 As shown, the unloading assembly 4 includes: a cable 20 and a gripper 21. One end of the cable 20 is fixedly connected to the cable drum 15, which is convenient for the storage and management of the cable 20. The cable drum 15 plays a supporting and tidying role, so that the cable 20 can be stored in an orderly manner when not in use, avoiding a messy situation, and improving the neatness and service life of the equipment. The other end of the cable 20 passes through the fixed pulley 19 and is fixedly connected to the gripper 21. The fixed pulley 19 plays a conducting and regulating role.

[0055] In some embodiments, Figure 5 As shown, the gripper 21 comprises:

[0056] A first fixing member 22 fixedly connected to one end of the cable 20, the first fixing member 22 firmly fixes the cable 20 on the second connecting member 24 to ensure that it will not loosen or fall off during operation;

[0057] The second connecting member 24 is detachably connected to the first fixing member 22 through the locking shaft pin 23, so that it can be quickly and conveniently disassembled when maintenance or replacement of parts is required. The second connecting member 24 is provided with a second fixing member 25 and a third fixing member 26 on the side away from the first fixing member 22. The second fixing member 25 and the third fixing member 26 are movably connected through a rotating assembly. The input end of the rotating assembly is communicatively connected with the output end of the communication module, so that the gripper 21 can receive and transmit information in real time during operation;

[0058] A first bucket 27 is provided at one end of the second fixing member 25 away from the rotating assembly, and a second bucket 28 having the same shape and size as the first bucket 27 is provided at one end of the third fixing member 26 away from the rotating assembly, so that the rotating assembly is operated and the second fixing member 25 and the third fixing member 26 are controlled to move so that the first bucket 27 and the second bucket 28 are closed, that is, when the gripper 21 grabs an object, such as fine particles such as sand, a closed space can be formed to prevent the material from falling.

[0059] During specific implementation, an angle sensor is provided in the gripper bracket 3, and the angle sensor is used to measure the rotation angle of the gripper bracket 3 in the horizontal direction; the angle sensor is communicated with the control module, and the user sets the starting and ending angles of the gripper bracket 3 and the opening and closing of the loading and unloading assembly through the control module to realize automatic loading and unloading of materials in the mine car. Preferably, the control module can record the starting and ending angles of the gripper bracket 3 and the opening and closing of the loading and unloading assembly, including: when the second support member 17 runs to the starting angle, the user controls the control module to record the current angle, the control module controls the electric motor 18 to rotate, puts down the gripper 21, controls the rotating assembly to open the second fixing member 25 and the third fixing member 26, and grabs the material, the control module controls the electric motor 18 to rotate in the opposite direction, lifts the gripper 21, and the control module further controls the first gear 32 to rotate. When the second support member 17 runs to the ending angle, the user controls the control module to record the current angle, the control module controls the electric motor 18 to rotate, puts down the gripper 21, controls the rotating assembly to open the second fixing member 25 and the third fixing member 26, and unloads the material. The control module controls the first gear 32 to rotate between two fixed angles to realize automatic material loading and unloading.

[0060] In some embodiments, the control module controls the rotation speed of the electric motor 18 via the communication module. A speed sensor is installed in the electric motor 18. The speed sensor measures the rotation speed of the electric motor 18 in real time and sends the rotation speed to the control module through the communication module. The control module calculates the acceleration of the electric motor 18 based on the received rotation speed at the previous moment and the real-time rotation speed. When the acceleration is equal to 0, the electric motor 18 will not trigger the cable reel 15 to rotate. When the acceleration is not 0, that is, when the cable 20 has an obvious acceleration, the electric motor 18 is controlled to trigger the cable reel 15 to reverse and retract the cable 15.

[0061] An angle sensor is provided in the gripper bracket of the present invention, and the angle sensor is used to measure the rotation angle of the gripper bracket 3 in the horizontal direction; the angle sensor is connected to the control module in communication, and the user sets the start and end angles of the gripper bracket 3 and the opening and closing of the loading and unloading assembly through the control module to realize automatic loading and unloading of materials by the mine car. The present invention increases the contact area with the ground by setting a crawler chassis assembly 1 parallel to the ground, and sets a protrusion 33 on the side where the crawler 8 contacts the ground, thereby increasing the bite force between the mine car and the ground, and effectively avoiding the phenomenon of the mine car slipping or even overturning due to a small contact area or insufficient bite force.
