[0029] 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.
[0030] Please refer to the attached Figures 1 to 4 , the open-pit coal mine cable car 100 and the mining and loading system according to the embodiment of the present invention are described in detail.
[0031] The mining and loading system of the embodiment of the present invention includes an electric shovel 200 and an open-pit coal mine cable car 100 .
[0032] The open-pit coal mine cable car 100 of the embodiment of the present invention includes a car body 1, a main cable winding device 2, a compensation cable winding device 3, a machine room 4, a control system 5 and a power system 6.
[0033] The vehicle body 1 has a mounting platform 11, and the upper surface of the mounting platform 11 is a platform surface. The main cable winding device 2 and the compensation cable winding device 3 are respectively located on both sides of the mounting platform 11. The main cable winding device 2 is wound with a main cable 21, and one end of the main cable 21 is used to connect to the power supply. The main cable winding device 2 can accommodate a rubber-sheathed cable with a diameter of 57 to 60 mm and a length of ≥300 m. The compensation cable winding device 3 is wound with a compensation cable 31, and one end of the compensation cable 31 is connected to the electric shovel 200. The compensation cable winding device 3 can accommodate a rubber-sheathed cable with a diameter of 57 to 60 mm and a length of ≥100 m.
[0034] The machine room 4 is arranged in the middle of the installation platform 11. The control system 5 and the power system 6 are arranged in the machine room 4. The control system 5, the other end of the main cable 21 and the other end of the compensation cable are all connected to the power system 6. The control system 5 is connected to the main cable winding device 2 to control the retraction and extension of the main cable 21, and the control system 5 is connected to the compensation cable winding device 3 to control the retraction and extension of the compensation cable 31.
[0035] When the mining and loading system of the embodiment of the present invention is in use, the electric shovel 200 moves forward to mine, the cable car 100 follows behind the electric shovel 200, the main cable 21 is connected to the power supply, and the compensation cable is connected to the electric shovel 200, thereby supplying power to the electric shovel 200. When the electric shovel 200 moves forward, the cable tension increases, and the compensation cable winding device 3 passively releases the cable. When the electric shovel 200 moves backward, the cable tension decreases, and the compensation cable winding device 3 actively retracts the cable.
[0036] When the electric shovel 200 is within the telescopic range of the compensating cable winding device 3, the stationary cable car 100 can move autonomously, and the compensating cable 31 on the compensating cable winding device 3 can be automatically retracted and released; when releasing the cable at any time, the number of remaining circles on the cable drum must not be less than 5 circles, otherwise an alarm will be triggered; the effective use range of the compensating cable 31 is 30 meters to 70 meters.
[0037] When the cable car 100 moves forward and backward, the main cable winding device 2 and the compensation cable winding device 3 automatically retract and release the cable. At any time when releasing the cable, the number of remaining turns on the cable drum must not be less than 5 turns, otherwise an alarm will be triggered; when the main cable winding device 2 retracts the cable, it must be manually operated to retract and release the cable when it is 20 meters away from the cable joint. In the automatic state, the cable is retracted and released by torque control. At this time, the cable joint will be pulled due to the action of the holding torque of the drum.
[0038] Therefore, the cable car 100 of the embodiment of the present invention can move with the electric shovel 200, ensure the power supply to the electric shovel 200, and realize the automatic cable retraction and release of the main cable 21 and the compensation cable 31. The degree of automation is high, thereby reducing the labor intensity of personnel, improving the efficiency of cable retraction and release, and thus improving mining efficiency.
[0039] The vehicle body 1 is a crawler chassis vehicle body 1. The crawler chassis has a large ground contact area, can provide better grip and stability in an open-pit coal mine environment, adapts to steep slopes and poorly flat ground, can reduce the risk of sliding and rollover during operation, helps to improve the efficiency of coal mining operations, and reduces downtime caused by poor ground conditions.
[0040] The upper end surface of the crawler chassis body 1 is a mounting platform 11 .
[0041] In some embodiments, the main cable winding device 2 includes a main drum 22, a first motor 23, a first reducer 24 and a first automatic cable arrangement mechanism 25. The main drum 22 is wound with a main cable 21. The first motor 23 is connected to the first reducer 24. The first reducer 24 is connected to the side of the main drum 22 to drive the main drum 22 to rotate. The first automatic cable arrangement mechanism 25 is arranged on the side of the main drum 22 away from the compensation cable winding device 3. The first motor 23 and the first reducer 24 are both connected to the control system 5.
[0042] The first motor 23 is a variable frequency speed regulating motor, Siemens brand, with a power of 5.5KW.
[0043] The main cable reel 2 is driven by a variable frequency speed regulating motor connected to a reducer to rotate the reel. A high voltage collector ring and a cable coupler interface are installed inside the main reel 22 to facilitate cable replacement. The cable access port on the reel is a waterproof structure. Four manholes are provided at one end of the main reel 22 for maintenance personnel to enter and exit. The manholes are provided with sealed and waterproof manhole covers.
[0044] In some embodiments, the main cable winding device 2 further includes a clamping mechanism 26, which includes a clamping roller 261, a clamping bracket 262 and a support 263, wherein the support 263 is perpendicular to the mounting platform 11, the clamping roller 261 is located on the clamping bracket 262 and is pivotally connected to the clamping roller 261, and the clamping bracket 262 is rotatably connected to the support 263 to maintain contact with the cable reel. The clamping mechanism 26 can press the main cable 21 wound on the main reel 22, and can ensure the neat arrangement of the main cable 21 on the main reel 22, and ensure the smoothness of the main cable 21 when it is retracted and released.
[0045] In some embodiments, the compensating cable winding device 3 includes a compensating drum 32, a second motor 33, a second reducer 34, and a second automatic cable arrangement mechanism 35. The second motor 33 is connected to the second reducer 34. The second reducer 34 is transmission-connected to the side of the compensating drum 32 to drive the compensating drum 32 to rotate. The second automatic cable arrangement mechanism 35 is arranged on the side of the supplementary drum away from the main drum 22. The second motor 33 and the second reducer 34 are both connected to the control system 5.
[0046] Specifically, the second motor 33 is a servo motor, and the second motor 33 is a Siemens brand with a power of 4KW. During operation, the compensation cable 31 is always in a tensioned state. When the electric shovel 200 moves forward, the cable is automatically released when the tension of the compensation cable 31 is greater than the stall torque. When the electric shovel 200 moves backward, the cable is automatically retracted when the cable tension is less than the stall torque, ensuring that the cable is always kept tensioned and close to the suspended state, so it will not be pressed by the cable car 100 itself or the electric shovel 200, so there is no need for a cable bracket to pick up the cable and put it on the side of the car. When the electric shovel 200 moves forward to the point where the remaining cable on the drum is less than the set value, an alarm is issued to prompt the driver to stop moving forward.
[0047] The compensating cable winding device 3 further includes an external high-voltage collector ring cabinet 36, which is connected to the other end of the compensating cable 31 and is connected to the power system 6. The high-voltage collector ring cabinet 36 is externally arranged on the outside of the compensating drum 32, which can reduce the demand for the internal space of the compensating drum 32 and make the layout more reasonable.
[0048] Specifically, counting sensors are provided on the main reel 22 and the compensation reel 32, and the counting sensors are connected to the control system 5. The counting sensors are used to monitor the number of rotations of the reels.
[0049] The first automatic cable arranging mechanism 25 and the second automatic cable arranging mechanism 35 both include a cable arranging motor, a lead screw, a column, a cable arranging device and a limit sensor. The cable arranging motor drives the lead screw through a reducer to drive the cable arranging device to move along the lead screw. Both ends of the lead screw are pivotally connected to the column respectively. The column is connected to the mounting platform 11 and is located next to the cable reel. The limit sensor is located on the column to detect the position of the cable arranging device.
[0050] The counting sensor on the reel will transmit the sensed quantity to the control system 5, and the control system 5 will calculate the command value and transmit it to the corresponding automatic cable arrangement mechanism's cable arrangement motor. The cable arrangement motor drives the lead screw through the reducer to make the cable arrangement device move at a constant speed of one wire diameter per one circle of the cable reel, ensuring that the cable reel is neatly placed. The cable arrangement speed can be changed at any time according to different cable diameters on the touch screen setting in the low-voltage control room.
[0051] Furthermore, a limit sensor is installed on the column. When the limit sensor detects that the cable arranging device is approaching, a signal is transmitted to the control system 5. The control system 5 instructs the cable arranging motor to reverse and realize reciprocating motion. When the cable arranging device stops at any position, the control system 5 can automatically memorize the direction of travel (it can also remember the direction after shutdown and power failure), and ensure the correct direction of movement when restarting. Unless the mode is switched to manual mode manually, the position of the cable arranging device and the direction of travel can be adjusted separately, and the cable can be manually retracted and released.
[0052] Specifically, the cable arrangement motor is a servo motor.
[0053] In some embodiments, a low-voltage room 41 is provided in the machine room 4, and the control system 5 includes a low-voltage control cabinet 51, a PLC controller, a touch screen, a low-voltage switch, a relay, a first remote control and a second remote control. The low-voltage control cabinet 51 is arranged in the low-voltage room 41, and a PLC controller is arranged in the low-voltage control cabinet 51. The PLC controller is connected to the touch screen, and the touch screen is arranged on the low-voltage control cabinet 51, and the main cable winding device 2 and the compensation cable winding device 3 are connected. The first remote control and the second remote control are both connected to the PLC controller. The first remote control controls the retraction and extension of the main cable winding device 2, and the second remote control controls the retraction and extension of the compensation cable winding device 3.
[0054] The PLC controller is the control part of the control system 5. The PLC controller is connected to the first motor 23, the first reducer, the second motor 33, the second reducer 34, the counting sensor and the limit sensor. The PLC controller controls the walking and steering of the vehicle body 1, controls the cable retracting and releasing of the main cable winding device 2, controls the automatic cable arrangement of the first cable arrangement mechanism, controls the cable retracting and releasing of the compensation cable winding device 3, and controls the automatic cable arrangement of the second cable arrangement mechanism.
[0055] The touch screen has the functions of indicating the equipment running status, setting equipment operating parameters and setting equipment basic parameters.
[0056] The vehicle operation mode is divided into remote control and manual control. The remote control can be operated by remote control on the electric shovel 200 or on the ground; the manual wire control operation handle is set on the control platform of the cable car 100. A wireless remote control mutual protection switch is configured in the cab of the electric shovel 200, and a mutual protection release switch is configured on the operating platform of the tail line cable retracting and releasing vehicle. The switching time of the wireless mutual protection switch is less than 20mS.
[0057] The remote control should be used in an environment of ±40℃ and a remote control distance of ≥200 meters. Each reel-and-unreel remote control can only control one device, and no signal interference should occur.
[0058] A high voltage chamber 42 and a resistance chamber 43 are provided in the machine room 4 . The power system 6 includes a transformer and a high voltage switch cabinet 61 . The transformer and the high voltage switch cabinet 61 are provided in the high voltage chamber 42 . A brake resistor is provided in the resistance chamber 43 .
[0059] Specifically, the machine room 4 is provided with insulation panels on the inner wall and ceiling of the low-pressure chamber 41, which can reduce the heat exchange between the external environment and the low-pressure chamber 41. In addition, an air conditioner is installed in the low-pressure chamber 41. When the ambient temperature is high, the air conditioner refrigeration ensures that the temperature in the low-pressure room is lower than 30°. When the temperature is low in winter, the auxiliary heating function is activated to ensure that the temperature in the low-pressure room is higher than 10°, thereby ensuring the normal operation of the electrical control components.
