The working principle of the utility model is:

Start the charging motor 3 and the main motor 13, and at the same time all the electromagnets in the system are in the power-off state, and the oil output from the oil outlets of the charging pump 2, the auxiliary pump 11, and the main pump 12 are returned to the oil through the corresponding charging pumps respectively. The electromagnetic overflow valve 21, the auxiliary pump oil return electromagnetic overflow valve 19, and the main pump oil return electromagnetic overflow valve 20 are directly returned to the oil tank 1, so as to realize the unloading start of the hydraulic pump group. 30 seconds after the oil charge motor 3 and the main motor 13 are started, the electromagnets on the oil return electromagnetic overflow valve 21 of the oil charge pump, the oil return electromagnetic overflow valve 19 of the auxiliary pump and the oil return electromagnetic overflow valve 20 of the main pump are activated, so that the above-mentioned The valve acts as a safety valve, while the charge pump 2 is in a low pressure relief state, the auxiliary pump 11 is in a constant pressure standby state, and the main pump 12 is in a load sensitive standby state.

In the manual mode of the cable storage winch, a corresponding control signal is given to the proportional directional valve 24 by manually operating the single lever to realize the two-way movement of the cable storage winch to retract and unwind the cable. Among them, the cable winding process: the pressure oil output by the main pump 12 is delivered to the P port of the proportional directional valve 24 through the main pump high pressure filter 16 and the main pump plate check valve 17, and then controlled by the serial pressure of the A port of the proportional directional valve 24 The first control main circuit 268 in the valve group 26 is delivered to the oil port A of the variable variable motor 30; the return oil flows out from the oil port B of the motor 30 and passes through the first cooling valve group interface 284 and the second cooling valve group interface 284 in the cooling valve group 28 in sequence. After cooling the oil circuit between the valve group interfaces 285 and the second control main circuit 269 in the pressure control valve group 26, it flows into the B port of the proportional directional valve 24, and then flows back to the oil tank 1 from the T port of the proportional directional valve 24, and discharges And vice versa for the cable action process.

During the cable storage and unwinding process of the cable storage winch, the proportional directional valve 24 leads the pressure and flow demand of the motor 30 to the main motor 30 through the load feedback shuttle valve 25 and the load feedback electromagnetic reversing valve 18 through its own C1 and C2 oil ports at the same time. On the load feedback oil port of the pump 13, the main pump 13 is a load feedback variable pump, which can automatically adapt to the pressure and flow requirements of the load. While the spool of the proportional directional valve 24 moves, the cartridge shuttle valve 261 on the pressure control valve group 26 passes the high-pressure oil from the first control port 57 or the second control port 58 of the pressure control valve group 26 through the gate opening valve group 32 The decompression action of the reducer is sent to the opening oil port of the reducer 31 to eliminate the mechanical braking force inside the reducer 31.

When the cable storage winch is in manual mode, the electromagnetic reversing valve 281 on the cooling valve group 28 is in a power-off state, so that the cooler 29 is placed outside the circuit, so as to prevent the high-pressure oil from causing damage to the cooler 29.

In the automatic mode of the cable storage winch, in order to ensure the moment of constant tension in the operation process, the motor 30 is always in the working condition of actively taking up the cable, that is, to ensure that the oil port A of the motor is high-pressure oil, and the oil port B of the motor is low-pressure oil, so The valve position of the proportional directional valve 24 remains at the right valve position all the time. Thus, the system take-up is an active mode, and the motor 30 is in a motor working condition, while the system unwinding is a passive way, and the motor 30 is in a pump working condition.

In the automatic mode of the cable storage winch, corresponding to the different winding layers of the steel cable, the corresponding output torque of the cable storage winch changes, and the pilot stage relief valve 265 in the pressure control valve group 26 can ensure that the oil ports A and The pressure difference between oil ports B is constant, and the displacement of the hydraulic motor is changed between different winding layers to adapt to the change of the output torque of the cable storage winch.

The support cylinder 34 is equipped with a linear displacement sensor, and according to the telescopic length of the piston rod, the winding layer of the cable on the cable storage winch can be obtained indirectly, and the relationship between the telescopic length of the piston rod and the set displacement of the motor 30 can be established. Relationship, in order to achieve the purpose of constant tension control.

The cable storage winch switches to the automatic mode, so that the pilot electromagnetic reversing valve 22, the proportional reversing valve 24, the pilot stage electromagnetic reversing valve 266 in the pressure control valve group 26, the electromagnetic reversing valve 281 in the cooling valve group 28, open The plug-in electromagnetic reversing valve 322 in the gate valve group 32 and the electromagnet on the motor 30 are powered on at the same time, and the pilot electromagnetic reversing valve 22 is powered on so that the oil output from the charge pump 2 is delivered to the charge oil of the pressure control valve group. Port 59, the proportional directional valve 24 is powered on to make the proportional directional valve 24 in the right valve position, and the pilot stage electromagnetic directional valve 266 in the pressure control valve group 26 is powered on so that the main spool 263 of the cartridge relief valve The opening pressure is determined by the set pressure of the pilot stage relief valve 265. The electromagnetic reversing valve 281 in the cooling valve group 28 is powered on so that the cooler 29 is connected in series to the low-pressure B chamber of the motor 30, and the gate valve group 32 is opened. The plug-in electromagnetic reversing valve 322 of the plug-in electromagnetic reversing valve 322 is energized so that the brake opening fluid drawn by the auxiliary pump 11 has been acting on the mechanical gate of the reducer 31 after being decompressed, so as to ensure that the mechanical braking force inside the reducer 31 is stably eliminated. At the same time, the electromagnet on the motor 30 is energized to make the displacement of the motor 30 continuously adjustable.

In the automatic mode of the cable storage winch, the oil circuit connection relationship in the active cable-winding process is roughly the same as the cable-winding action in the manual mode. The opening pressure of the core 263 is determined by the set pressure of the pilot stage relief valve 265, and the set pressure of the pilot stage relief valve 265 is lower than the set pressure of the main pump 12, so during the active cable winding process, the plug-in The main spool 263 of the type relief valve is always in a relief state, thereby ensuring that the pressure difference between the oil port A and the oil port B of the motor remains unchanged.

When the cable storage winch is in automatic mode, the connection relationship of the oil circuit in the passive cable unwinding process is roughly the same as that in the active cable take-up process. The high-pressure oil flowing out of port A overflows to the oil port B of the motor 30 through the main spool 263 of the cartridge relief valve in the pressure control valve group 26. Due to the loss of the overflow, the temperature of the overflowing oil will decrease. raised. In order to prevent the high-temperature oil from damaging the hydraulic components, a cooler 29 is connected in series to the oil port B of the motor 30 , so that the high-temperature oil is supplied to the oil port B of the motor 30 after being cooled.

During operation, through the magnetic proximity switch installed on the guide wheel, the change of the cable discharge angle is automatically detected at all times. When the change of the cable discharge angle exceeds the allowable value, the corresponding electric signal is automatically input to the three-position four-way electromagnetic reversing valve 335 , thereby controlling the quantitative motor 35 to move in the direction of reducing the change of the cable discharge angle, and the moving speed of the motor is set by the superimposed double one-way throttle valve 334 .

The main pump 12 of the cable storage winch adopts the load sensitive variable pump, and for the whole operation process, it must be in the starting state all the time. However, for the towing process of long-term operation, the motor 30 of the cable storage winch is in a locked-rotor state, and the pump source is not required to provide flow. Power off, so that the main pump 12 is in a state of constant pressure and no output flow, so as to achieve the purpose of energy saving.
