Description

Technical Field

[0001] The utility model relates to the field of winches, in particular to a novel hydraulic winch motor control valve group. Background Art

[0002] A winch motor control valve is a device used to regulate and control the operation of the motor in a winch. It ensures that the motor can operate smoothly and efficiently by precisely adjusting the flow and pressure in the hydraulic or pneumatic system. A winch motor control valve usually has multiple functions, such as starting, stopping, accelerating, decelerating, and emergency braking, thereby achieving precise control of the winch. This type of control valve is widely used in many fields such as construction, mining, ports, and lifting, and is an important component to ensure the safe and reliable operation of equipment.

[0003] Currently, there is a Chinese patent document CN202121752489.X for a winch hydraulic control system and a crane, which includes: an oil tank for storing hydraulic oil; an oil pump connected to the oil tank and used to move the hydraulic oil in the oil tank; an oil inlet circuit, one end of which is connected to the oil outlet of the oil pump and the other end is connected to the oil inlet of the winch motor; an oil return circuit, one end of which is connected to the oil outlet of the motor and the other end is connected to the oil tank; a control valve, which is connected to the oil inlet circuit and the oil return circuit respectively, and the control valve has an on state and a off state; when the control valve is in the on state, the oil pump stops driving the motor. When the control valve of the utility model is in the off state, hydraulic oil enters the motor through the oil pump and the oil inlet circuit, causing the motor to rotate; when the control valve is in the on state, the oil pump stops driving the motor.

[0004] However, the above patent has certain defects when in use. Since the hydraulic oil enters the motor through the oil pump and the oil inlet and the flow rate cannot be controlled, the running speed of the motor is unstable and can only be driven at a single speed. It cannot meet the needs of fine speed adjustment in different working environments, affecting working efficiency and safety.

[0005] For this reason, a new type of hydraulic winch motor control valve group is proposed here to solve the above-mentioned problems. Utility Model Content

When the sliding column electromagnetic core is in the initial position, the oil transported from the circulating oil pump 24 to the oil inlet The oil flows from the oil inlet pipe 25 into the oil inlet port 21, and then enters the interior of the electromagnetic reversing valve 13. Under the diversion of the columnar electromagnetic core, the oil will flow from the first oil delivery port 11 into the first oil circuit 8, and the first oil circuit 8 enters the hydraulic motor 7. At this time, the hydraulic motor 7 rotates forward, and then the oil flows back to the second oil delivery port 12 through the second oil circuit 9. Under the diversion of the columnar electromagnetic core, the oil from the second oil delivery port 12 flows back to the conversion pipe 28 from the second oil outlet 23, and then flows into the circulating oil pump 24. When the oil is diverted by the control board, the oil flows back to the conversion pipe 28 from the second oil outlet 23, and then flows into the circulating oil pump 24. After the electromagnetic chamber 14 is energized, the sliding column electromagnetic core is excited by the current, and the valve core 17 is subjected to thrust, causing the oil to change its flow direction. The oil in the electromagnetic reversing valve 13 will flow from the second oil delivery port 12 into the second oil circuit 9, thereby driving the hydraulic motor 7 to reverse. The oil then flows back to the first oil delivery port 11 through the first oil circuit 8. The oil in the second oil delivery port 12 flows back to the conversion pipe 28 from the second oil outlet 23 under the diversion of the column electromagnetic core, and then flows into the circulating oil pump 24 to achieve efficient energy conversion, thereby improving the overall operating efficiency.

[0040] Specifically, a control console 2 is provided on the top of the hoist body 1 , and the control console 2 is located on one side of the operating table 3 . A connecting line 15 is provided on the back of the control console 2 , and the other end of the connecting line 15 is connected to the electromagnetic chamber 14 .

[0041] In this embodiment, a connecting line 15 is provided on the back of the console 2, and the other end of the connecting line 15 is connected to the electromagnetic chamber 14. The console 2 controls the current input of the electromagnetic chamber 14 to achieve stroke control of the sliding column electromagnetic core in the electromagnetic reversing valve 13, thereby ensuring the flow rate of the oil, and further achieving the control of the forward and reverse rotation speed of the shaft 5 at the output end of the hydraulic motor 7.

[0042] Specifically, first support frames 10 are provided on both sides of the bottom of the hydraulic motor 7 , and the first support frames 10 are connected to the top of the hoist body 1 .

[0046] Specifically, the console 2 is electrically connected to the electromagnetic chamber 14 and the circulating oil pump 24 .

[0047] In this embodiment, the console 2 is electrically connected to the electromagnetic chamber 14 and the circulating oil pump 24. The console 2 controls the electromagnetic chamber 14 through the connecting line 15. When current is applied to the electromagnetic chamber 14, the control piston 16 pushes the valve core 17. The push of the valve core 17 drives multiple valve covers 18 on the valve core 17, thereby controlling the oil flow of the oil inlet 21, the first oil outlet 22, the second oil outlet 23, the first oil delivery port 11, and the second oil delivery port 12 on the electromagnetic reversing valve 13. When the console 2 de-energizes the electromagnetic chamber 14 through a command, the cylindrical electromagnetic core returns to its initial position under the action of the return spring 20. At the same time, the console 2 controls the working state of the circulating oil pump 24 to ensure smooth operation and efficient energy conversion of the entire system.

[0048] The principle of the present utility model is as follows: after the circulating oil pump 24 is started through the control console 2, the oil flows from the oil inlet pipe 25 into the oil inlet port 21, and then enters the interior of the electromagnetic reversing valve 13. Under the diversion of the columnar electromagnetic core in the initial position, the oil will flow from the first oil delivery port 11 into the first oil circuit 8, and the first oil circuit 8 enters the hydraulic motor 7. At this time, the hydraulic motor 7 rotates forward, thereby driving the traction drum 6 on the rotating shaft 5 to rotate forward, and then the oil flows back to the second oil delivery port 12 through the second oil circuit 9. Under the diversion of the columnar electromagnetic core, the oil of the second oil delivery port 12 flows back to the conversion pipe 28 from the second oil outlet 23, and then flows into the circulating oil pump 24. When the traction drum 6 needs to be reversed When the electromagnetic chamber 14 is energized through the workbench, the sliding column electromagnetic core is excited by the current, and the valve core 17 is thrust, causing the oil to change flow direction. The oil in the electromagnetic reversing valve 13 will flow from the second oil delivery port 12 into the second oil circuit 9, thereby driving the hydraulic motor 7 to reverse, and then the oil will flow back to the first oil delivery port 11 through the first oil circuit 8. The oil in the second oil delivery port 12 flows back to the conversion pipe 28 from the second oil outlet 23 under the diversion of the column electromagnetic core, and flows back to the circulating oil pump 24, forming a complete oil circuit cycle, ensuring the continuous and stable operation of the system. When the electromagnetic chamber 14 is de-energized, the column electromagnetic core returns to its initial position under the action of the reset spring 20.
