[0049] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0050] The traction machine and its driving system according to the present invention will be described below with reference to the accompanying drawings.

[0051] like Figure 1 As shown, it is a structural schematic diagram of a traction machine provided according to an embodiment of the present invention; Figure 2 As shown, it is a structural schematic diagram of a rotary drive member 10 provided according to an embodiment of the present invention; Figure 3 , which is a structural block diagram of a driving system provided according to an embodiment of the present invention.

[0052] The traction machine of the embodiment of the present invention includes a traction wheel assembly 70 and a drive system, and the drive system includes:

[0053] The rotary drive member 10 is drivingly connected to the traction wheel assembly 70;

[0054] A drive control device (not shown in the figure), which is electrically connected to the rotary drive member 10 and is used to control the start and stop of the rotary drive member 10;

[0055] The energy storage device 30 stores energy and includes a first energy storage mechanism and a second energy storage mechanism. The first energy storage mechanism and the second energy storage mechanism are both electrically connected to the drive control device. The drive control device is configured as follows:

[0056] Determine whether the traction wheel assembly 70 is in working condition;

[0057] When the traction wheel assembly 70 is in the working state, the first energy storage mechanism and / or the second energy storage mechanism is controlled to supply energy to the rotary drive member 10 .

[0058] The traction wheel assembly 70 of the traction machine can pull or release the rope to transport wires, cables, traction ropes, etc. The traction wheel assembly 70 is driven by a drive system, which includes a rotating drive member 10 (such as a motor), an energy storage device 30 and a drive control device (such as a motor drive controller). Among them, the rotating drive member 10 is connected to the traction wheel assembly 70 by driving, the energy storage device 30 stores energy and is used to supply energy to the rotating drive member 10, and the drive control device is electrically connected to the rotating drive member 10 and can control the start and stop of the rotating drive member 10. The energy storage device 30 includes a first energy storage mechanism and a second energy storage mechanism, and the first energy storage mechanism and the second energy storage mechanism can supply energy to the rotating drive member 10 separately or simultaneously, so that the rotating drive member 10 rotates and drives the traction wheel assembly 70 to work. Compared with the traditional high-power diesel engine driving the traction wheel assembly 70 through a hydraulic system, the first energy storage mechanism and the second energy storage mechanism of the present invention directly supply energy to the rotating drive member 10, with lower energy loss and lower noise.

[0059] In one embodiment, the first energy storage mechanism and the second energy storage mechanism are a battery module 31 and a range extender mechanism 32, respectively. The battery module 31 can store electrical energy, and can directly provide electrical energy to the rotary drive member 10, and can recover energy when the motor rotates passively. The range extender mechanism 32 can be a diesel engine, a gasoline engine, a hydrogen engine, etc. The range extender mechanism 32 can provide additional electrical energy, thereby extending the endurance of the rotary drive member 10 or increasing the electrical power input to the rotary drive member 10. Compared with the combined drive of a high-power diesel engine and a hydraulic system, the structure provided by the embodiment of the present invention is more energy-saving and environmentally friendly, has lower noise, and optimizes the working environment of the traction machine.

[0060] In one embodiment, the drive control device includes: a drive module 21, which is electrically connected to the battery module 31 and the range extender 32, and the drive module 21 is used to obtain the power demand of the rotating drive member 10 and send a power demand signal; a main control module 22, which is electrically connected to the drive module 21 and is used to control the connection and disconnection between the battery module 31 and the drive control device and the connection and disconnection between the range extender 32 and the drive control device according to the power demand signal. The main control module 22 is the control center of the traction machine. The drive module 21 can be electrically connected to the battery module 31 and the range extender 32, and can obtain the power demand of the rotating drive member 10, and send the power demand to the main control module 22. The main control module 22 can control the battery module 31 and / or the range extender 32 to supply energy to the rotating drive member 10 according to the power demand. With the above-mentioned drive control device, the battery module and the range extender 32 can be started to supply energy in a targeted manner in combination with the power demand of the rotating drive member 10, which can not only save energy, but also prevent the insufficient power of the rotating drive member 10, causing the traction wheel assembly 70 to be unable to rotate normally.

[0061] In one embodiment, Figure 4 As shown, it is a schematic diagram of the energy supply mode of the drive system provided according to an embodiment of the present invention. The main control module 22 is further configured to: determine the driving load of the rotating drive member 10 according to the power demand signal; obtain the remaining power of the battery module 31; when the remaining power of the battery module 31 is greater than the first preset power threshold and the driving load is less than the preset load threshold, control the battery module 31 to provide energy for the rotating drive member 10 alone; when the remaining power of the battery module 31 is greater than the second preset power threshold and the driving load is greater than the preset load threshold, control the battery module 31 and the range-extending mechanism 32 to provide energy for the rotating drive member 10 at the same time, wherein the first preset power threshold is greater than the second preset power threshold; when the remaining power of the battery module 31 is greater than the second preset power threshold and less than the first preset power threshold, and the driving load is equal to the preset load threshold, the range-extending mechanism 32 provides energy for the rotating drive member 10 alone; when the remaining power of the battery module 31 is less than the second preset power threshold, the range-extending mechanism 32 provides energy for the rotating drive member 10 alone.

[0062] The main control module 22 can determine the driving load of the rotating drive member 10 according to the power demand signal sent by the main control module 22. The main control module 22 can also determine the energy supply mode of the drive system according to the size of the driving load and the remaining power of the battery module 31. When the driving load of the rotating drive member 10 is large, the battery module 31 and the range extension mechanism 32 are required to supply energy to the rotating drive member 10 at the same time, otherwise it will cause insufficient power of the rotating drive member 10 and the rotating drive member 10 cannot work normally. When the power of the battery module 31 is less than a certain power value, the main control module 22 of the present invention can give priority to using the range extension mechanism 32 to supply energy to the rotating drive member 10, so that the power of the battery module 31 is kept at a high state, to prevent the battery from failing to work due to insufficient power when the load of the rotating drive member 10 is high, thereby causing the rotating drive member 10 to fail to work normally. When the power of the battery module 31 is greater than a certain power value, the main control module 22 of the present invention can give priority to using the battery module 31 to supply energy to the rotating drive member 10, because the battery module 31 is more energy-saving and has lower noise than the range extension mechanism 32. Among them, the first preset power threshold is greater than the second preset power threshold. When the power of the battery module 31 is greater than the first preset power threshold, the remaining power of the battery module 31 is in a relatively sufficient state; when the power of the battery module 31 is less than the first preset power threshold and greater than the second preset power threshold, the remaining power of the battery module 31 is insufficient; when the power of the battery module 31 is less than the second preset power threshold, the battery module 31 is in a low-power state or a state where it cannot discharge.

[0063] Specifically, Figure 4 As shown, when the driving load is greater than the first preset load threshold, the battery module 31 and the range-extending mechanism 32 need to simultaneously supply energy to the rotating drive member 10 to meet the power demand of the rotating drive member 10. When the driving load is less than the first preset load and the power of the battery module 31 is greater than the first preset power threshold, the battery module 31 is used to supply energy to the rotating drive member 10 alone. Among them, the required power corresponding to the first preset load threshold is the maximum discharge power of the battery module, and the required power corresponding to the second preset load threshold is the maximum output power of the range-extending mechanism 32. When the remaining power of the battery module 31 is less than the first preset power threshold and the driving load is less than the second preset load threshold, the range-extending mechanism 32 charges the battery module 31 while driving the rotating drive member 10. When the remaining power of the battery module 31 is less than the first preset power threshold and the load is zero, the range-extending mechanism 32 outputs energy to charge the battery module 31. When the remaining power of the battery module 31 is less than the first preset power threshold and the driving load is equal to the second preset load threshold, the range-extending mechanism 32 drives the rotating drive member 10 alone. When the power level of the battery module 31 is less than the second preset load threshold and the driving load is greater than the second preset load threshold, the traction machine stops operating.

[0064] In one embodiment, the traction machine further includes a human-machine interaction module 40 electrically connected to the main control module 22, and the main control module 22 is further configured to: obtain control instructions input by the human-machine interaction module 40; and adjust the energy supply mode of the rotating drive member 10 according to the control instructions. In some special cases, the energy supply mode of the rotating drive member 10 requires a specific energy supply mode. Therefore, the traction machine provided by the embodiment of the present invention further includes a human-machine interaction module 40 electrically connected to the main control module 22. The human-machine interaction module 40 can transmit user instructions to the main control module 22. After the main control module 22 obtains the control instructions input by the human-machine interaction module 40, it can adjust the energy supply mode of the drive system according to the control instructions. For example, the noise generated when the battery module 31 supplies energy is less than the noise generated when the range extender mechanism 32 supplies energy. When constructing in a residential area, a quiet environment needs to be maintained. The user controls the drive mechanism through the human-machine interaction module 40 to always use the battery module 31 to supply energy to the rotating drive member 10.

[0065] In one embodiment, Figure 3 As shown, the drive system also includes a power management module 50 electrically connected to the drive module 21, and the power management module 50 is used to convert the energy generated by the first energy storage mechanism and the second energy storage mechanism and transmit it to the drive module 21. The power management module 50 can convert the energy transmitted from the first energy storage mechanism and the second energy storage mechanism, and transmit the converted energy to the drive module 21. For example, the first energy storage mechanism is a battery module 31, the second energy storage mechanism is an extended-range mechanism 32, the rotating drive member 10 is a motor, and the drive module 21 is a motor drive module 21. The power management module 50 can adjust the electric energy transmitted by the battery module 31 and the extended-range mechanism 32 so that the voltage and current of the adjusted electric energy can be safely transmitted to the motor drive module 21. By using the above-mentioned power management module 50, the energy transmitted by the first energy storage mechanism and the second energy storage mechanism can be converted and transmitted, so that the energy transmission process of the traction machine is safer and smoother.

[0066] In one embodiment, Figure 2As shown, the rotary drive member 10 also includes a reducer 11 and a brake 12 coaxially connected to the reducer 11, and the drive system also includes an auxiliary hydraulic module 60 for controlling the braking or release of the brake 12. The tractor needs to brake during the traction process and after the traction is completed. The brake 12 can be coaxially connected to the reducer 11 of the rotary drive member 10, and the rotary drive member 10 can be braked when the brake 12 stops rotating. The brake 12 is controlled by the auxiliary hydraulic module 60, and the main control module 22 can be electrically connected to the auxiliary hydraulic module 60 and send a control signal to the auxiliary hydraulic module 60. When the auxiliary hydraulic module 60 receives the control signal, it can control the brake 12 to brake or release. With the above-mentioned drive system, the traction wheel assembly 70 can be braked or released in time, so that the tractor can be braked and released more timely.

[0067] In one embodiment, Figure 5 As shown, it is a schematic diagram of the hydraulic principle of the auxiliary hydraulic module 60 provided according to an embodiment of the present invention. The auxiliary hydraulic module 60 includes a main pump 61, which supplies oil to the brake 12 through an oil supply oil circuit.

The auxiliary hydraulic module 60 includes a main pump 61, a multi-way valve 62 and a brake valve 63. The main pump 61 is used to provide power for the hydraulic oil in the auxiliary hydraulic module 60 and transmit the hydraulic oil to the oil supply oil circuit. The multi-way valve 62 and the brake valve 63 can adjust the flow direction and on-off of the hydraulic oil on the oil supply oil circuit, thereby controlling the brake 12 to perform braking or release. By adopting the above-mentioned auxiliary hydraulic module 60, the brake 12 can be controlled through the hydraulic oil circuit, and the control method is reliable and efficient. The setting of the auxiliary hydraulic module 60 can make the braking torque of the brake 12 more stable when performing braking.

[0068] In one embodiment, Figure 2 As shown, the rotary drive member 10 includes a drive motor 13, a reducer 11 and a first gear 14 connected in a coaxial driving manner, and the traction wheel assembly 70 includes two spaced traction wheels 71, each traction wheel 71 is provided with a traction rope around its outer periphery, and the axial ends of the two traction wheels 71 are provided with a second gear 15, and the first gear 14 is meshed with the outer peripheries of the two second gears 15. A reducer 11, a first gear 14 and a second gear 15 are arranged between the drive motor 13 and the traction wheels 71, and the reducer 11 can transmit torque, adjust the rotation rate and increase the transmission torque, and the reducer 11 is coaxially connected to the brake 12, and the brake 12 can control the brake of the reducer 11 to brake the traction wheel 71. The first gear 14 is meshed with the second gears 15 of the two traction wheels 71, and when the reducer 11 drives the first gear 14 to rotate, the first gear 14 can drive the two second gears 15 to rotate synchronously in the same direction, thereby causing the two traction wheels 71 to rotate synchronously in the same direction to achieve the winding or unwinding of the traction rope.

[0069] In the above-mentioned driving system of the traction machine, the driving system includes a rotating driving member 10, a driving control device and an energy storage device 30, wherein the energy storage device 30 includes a battery module 31 and a range-extending mechanism 32. The driving module 21 in the driving control device can obtain the power demand of the rotating driving member 10 and send a power demand signal to the main control module 22. The main control module 22 can determine whether the battery module 31 and / or the range-extending module provide energy for the rotating driving member 10 according to the load of the rotating driving member 10 and the remaining power of the battery module 31. The power management module 50 in the driving system can convert the energy in the battery module 31 and the range-extending mechanism 32, and transmit the converted energy to the driving module 21. The use of the above-mentioned driving system of the traction machine can reduce the energy loss of the traction machine, reduce the noise of the traction machine, and optimize the working environment near the traction machine.
