The hydraulic pump station 1 is connected to the tailstock motor 21 through an oil pipe, the tailstock motor 21 is connected to the take-up tailstock 22, the capstan rope 23 is wound around the take-up tailstock 22, the head end of the capstan rope 23 extends out of the take-up tailstock 22, the capstan rope 23 is also wound around the drum 241 of the capstan 24, the speed sensor 25 is arranged on the capstan 24, and the tension sensor 26 is installed on the capstan rope 23. The speed sensor 25 and the tension sensor 26 are electrically connected to the hydraulic pump station 1, the speed sensor 25 is used to detect the rotation speed of the capstan 24, the hydraulic pump station 1 is used to control the action of the tailstock motor 21 according to the rotation speed detected by the speed sensor 25, and adjust the driving oil pressure of the tailstock motor 21 according to the tension detected by the tension sensor 26.

[0025] In the present invention, the hydraulic pump station 1 is connected to the tailstock motor 21 through an oil pipe. The hydraulic pump station 1 drives the tailstock motor 21 to move. The tailstock motor 21 is connected to the take-up tailstock 22. The tailstock motor 21 drives the take-up tailstock 22 to rotate. The winch rope 23 is wound around the take-up tailstock 22. The head end of the winch rope 23 extends out of the take-up tailstock 22 and then winds around the drum 241 of the winch machine 24. By arranging a speed sensor 25 on the winch machine 24 and installing a tension sensor 26 on the winch rope 23, the speed sensor 25 detects the rotation speed of the drum 241 in real time. The tension sensor 26 detects the tension of the capstan rope 23 in real time. The speed sensor 25 and the tension sensor 26 are electrically connected to the hydraulic pump station 1. The hydraulic pump station 1 adjusts the action of the tailstock motor 21 according to the speed detected in real time by the speed sensor 25, thereby achieving real-time adjustment of the speed of the take-up tailstock 22, so that the take-up tailstock 22 and the capstan 24 are kept synchronized. At the same time, the driving oil pressure of the capstan working mechanism 2 is adjusted according to the tension detected by the tension sensor 26, so that the capstan rope 23 always maintains a constant pressure, which is more efficient and safer.

[0026] In some embodiments, as Figure 2 and Figure 3As shown, the hydraulic pump station 1 includes a frame 11 and a driving member 12, a hydraulic pump 13, an oil tank 14, a control box 15 and a centralized control valve group 16 arranged on the frame 11. The driving member 12 and the hydraulic pump 13 are arranged on the lower left side of the frame 11, the oil tank 14 is arranged on the right side of the frame 11, and the centralized control valve group 16 and the control box 15 are arranged at the front of the frame 11. By reasonably arranging various devices on the frame 11, the overall structure of the hydraulic pump station 1 is more compact, the footprint is smaller, and the movement of the hydraulic pump station 1 is convenient; the driving member 12 can be a diesel engine or a diesel engine, etc. The driving member 12 is connected to the hydraulic pump 13, and the hydraulic pump 13 is connected to the oil tank 14 and the centralized control valve group 16 through an oil pipe. The hydraulic The pressure pump 13 is actuated, and the hydraulic pump 13 delivers the oil in the oil tank 14 to the centralized control valve group 16. The centralized control valve group 16 is connected to the tailstock motor 21 through an oil pipe. The control box 15 is electrically connected to the speed sensor 25, the tension sensor 26 and the centralized control valve group 16. The control box 15 receives the speed signal from the speed sensor 25, and then adjusts the flow of the hydraulic oil in the centralized control valve group 16 according to the speed signal. The flow rate of the hydraulic oil in the centralized control valve group 16 determines the speed of the tailstock motor 21, and the tailstock motor 21 drives the take-up tailstock 22 to move. Therefore, by adjusting the flow rate in the centralized control valve group 16, the speed of the take-up tailstock 22 can be adjusted to ensure synchronization with the winch grinder 24. The tension can be pre-set in the control box 15, for example, 100 kg. The tension sensor 26 detects the actual tension of the winch rope 23 in real time. When the actual tension is inconsistent with the preset tension, the control box 15 controls the centralized control valve group 16 to operate, and the total oil pressure inside the centralized control valve group 16 changes, that is, the driving oil pressure of the tailstock motor 21 is changed, so that the constant tension is always maintained on the winch rope 23.

[0027] In some embodiments, as Figure 2 、 Figure 5 and Figure 6As shown, the centralized control valve group 16 includes an oil distribution valve block 161 and a working valve block 162. The oil distribution valve block 161 is connected to the hydraulic pump 13 and the oil tank 14 through an oil pipe. The oil distribution valve block 161 is communicated with the working valve block 162. The oil distribution valve block 161 is used to distribute oil to each working valve block 162. One working valve block 162 is correspondingly connected to one tailstock motor 21. Each working valve block 162 is provided with two working oil ports 1621, which are respectively connected to the oil inlet and oil return port of the tailstock motor 21. The working valve block 162 is provided with a solenoid valve 163, which is connected to the control box 15. The solenoid valve 163 is used to adjust the oil pressure inside the working valve block 162. The control box 15 adjusts the valve opening of the solenoid valve 163 on the corresponding working valve block 162 according to the speed signal fed back by the speed sensor 25. After the valve opening changes, the oil pressure in the corresponding working valve block 162 also changes accordingly. After the oil pressure in the working valve block 162 changes, the speed of the tailstock motor 21 also changes accordingly. The tailstock motor 21 drives the take-up tailstock 22 to move. Therefore, the speed of the take-up tailstock 22 is adjusted by changing the valve opening of the solenoid valve 163. The entire adjustment process does not require manual operation, saving manpower, and the synchronization accuracy of the winch grinder 24 and the take-up tailstock 22 is higher, safer and more reliable.

[0028] In some embodiments, as Figure 2 、 Figure 5 and Figure 6 As shown, the hydraulic pump station 1 also includes a pressure gauge 17. The oil distribution valve block 161 is provided with a main oil inlet 1611, a main oil return port 1612, and a pressure measuring port 1613. The main oil inlet 1611 is connected to the oil outlet of the hydraulic pump 13 via an oil pipe, the main oil return port 1612 is connected to the oil inlet of the oil tank 14 via an oil pipe, and the pressure measuring port 1613 is connected to the pressure gauge 17 via an oil pipe. The pressure gauge 17 is used to detect the oil pressure inside the oil distribution valve block 161. The pressure gauge 17 allows staff to directly observe the oil pressure inside the oil distribution valve block 161, that is, the total oil pressure of the centralized control valve group 16, which facilitates monitoring of the oil pressure in the centralized control valve group 16 and prevents excessive oil pressure from causing safety accidents.

[0029] In some embodiments, as Figure 5As shown, the oil distribution valve block 161 is provided with an overflow port 1614, to which a overflow valve 166 is connected. Overflow valve 166 is a proportional overflow valve and is further connected to the oil tank 14 via an oil pipe. Relief valve 166 is also electrically connected to the control box 15. Relief valve 166 is used to output the hydraulic oil in the oil distribution valve block 161 to the oil tank 14 to adjust the driving oil pressure for the tailstock motor 21. Relief valve 166 receives a control signal from the control box 15 and outputs excess hydraulic oil to the oil tank 14, thereby maintaining a constant oil pressure in the oil distribution valve block 161. The oil pressure in the oil distribution valve block 161 is also the driving oil pressure of the tailstock motor 21. Therefore, the driving oil pressure of the tailstock motor 21 can be kept stable, and the tension on the winch rope 23 can be maintained constant.

[0030] In some embodiments, as Figure 5 and Figure 6 As shown, the centralized control valve assembly 16 also includes an operating handle 164, which is located on the front side of the working valve block 162 and connected to the solenoid valve 163. The operating handle 164 is used to manually control the valve opening of the solenoid valve 163. Under normal circumstances, the valve opening of the solenoid valve 163 is controlled by the control box 15, thereby controlling the oil pressure in the working valve block 162. In some emergency situations, the operator can directly operate the operating handle 164 to control the valve opening, which is more convenient.

[0031] In some embodiments, combined Figure 2 and Figure 6 As shown, the centralized control valve group 16 is also provided with an oil drain port 165, which is connected to the oil inlet of the oil tank 14 through an oil pipe. The oil drain port 165 can drain excess internal leakage oil inside the centralized control valve group 16 to the oil tank 14 to maintain the stability of the oil pressure in the centralized control valve group 16.

[0032] The driving member 12 can be directly connected to the municipal power supply for use, but when the hydraulic capstan unit is used in some field locations with poor power supply conditions, there is usually no municipal power supply available nearby, which limits the use scenarios of the hydraulic capstan unit.

[0033] In some embodiments, as Figure 2 and Figure 3 As shown, the hydraulic pump station 1 further includes a power supply 18, which can be a battery or a storage battery. The power supply 18 is disposed adjacent to the driving member 12 and is connected to the driving member 12. The power supply 18 supplies power to the driving member 12, allowing the driving member 12 to operate normally even in field locations with poor power supply conditions, thereby enhancing the maneuverability of the hydraulic capstan unit and making it more convenient to use.

[0034] In some embodiments, as Figure 2As shown, the hydraulic pump station 1 also includes a first starting switch 19, which is connected to the power supply 18 and is used to control the on / off state of the power supply 18. During operation, the first starting switch 19 must be turned on before the power supply 18 begins supplying power to the drive 12. During non-operation, the first starting switch 19 must be turned off, and the power supply 18 stops supplying power to the drive 12. The provision of the first starting switch 19 improves the safety of the hydraulic capstan unit.

[0035] In some embodiments, as Figure 2 As shown, the hydraulic pump station 1 further includes a second starting switch 10, which is connected to the driving member 12 and is used to control the operation of the driving member 12. The driving member 12 starts to operate when the second starting switch 10 is turned on, and stops when the second starting switch 10 is turned off. By providing the second starting switch 10 to control the start and stop of the driving member 12, operation is safer.
