Embodiment Construction

[0029] Such as figure 1 As shown, when lifting the net, the high-pressure oil enters the hydraulic motor (3, 12) through the proportional reversing valve to drive the hydraulic winch to rotate forward and lift the net. When the external load increases, the pressure of the hydraulic system increases, and the pulling force of the wire mesh machine increases. When the proportional directional control valve is in the left or right position, it can stabilize the pressure difference between the inlet and outlet ports of the proportional directional control valve by changing its own flow rate, avoiding the influence of load changes on the flow control, thereby realizing proportional flow control. In the neutral position, the valve is in the zero position when it is not in action, so the pressure oil flows out from the neutral oil return port of the manual reversing valve, and returns to the oil tank through the oil return pipe. At this time, the system is in an unloaded state, and th...

Abstract

The invention discloses a fishing boat trawl winch tension control system. A first oil pressure sensor is arranged on a hauling side oil way of a first hydraulic motor; an oil inlet of a first pilot valve is connected with a remote control port of a first overflow valve; an outlet of the first pilot valve is connected with an oil tank; an oil inlet of the first overflow valve is connected with a hauling side oil port of the first hydraulic motor; the hauling side oil port of the first hydraulic motor is connected with a port A of a first proportional reversing valve; a shooting side oil port of the first hydraulic motor is connected with a port B of the first proportional reversing valve; the port A of the first proportional reversing valve is connected with an oil return port of a first balance vale; an oil return port of the first proportional reversing valve is connected with the oil tank; an oil inlet of the first balance valve is connected with the hauling side oil port of the first hydraulic motor; a control oil port of the first balance valve is connected between the port A of the first proportional reversing valve and the hauling side oil port of the first hydraulic motor; and the first overflow valve and the first pilot valve are respectively connected between the hauling side oil port and the shooting side oil port of the first hydraulic motor in parallel.

Description

technical field [0001] The invention belongs to the technical field of fishing equipment, in particular to a fishing boat trawl winch tension control system. Background technique [0002] The trawl winch is the most important equipment in the fishing operation of the trawler. During the trawling process, the heave motion of the hull caused by the waves or the steering of the fishing boat will cause the tension fluctuation on the drag line of the net gear, which has a great influence on the performance and life of the drag line winch. In addition, excessive fluctuations in the tension of the trawl net will also affect the expansion of the trawl net opening and the deformation of the net opening, resulting in low fishing efficiency. Therefore, it is of great significance to control the tension of the trawl winch. Contents of the invention [0003] The purpose of the present invention is to provide a tension control system of a trawl winch, which is used to solve the control...
