Embodiment 1

[0025] refer to figure 1 In this embodiment, the working control system of the windlass windlass includes a servo pump station PS and a plurality of first direction switching valves. Each first direction switching valve corresponds to a winch or windlass. Specific instructions are given below.

[0026] Corresponding to the first direction switching valve 210 of windlass W1, its first oil port 211 and second oil port 212 are connected to the oil outlet of the servo pump station PS, and the third oil port 213 and fourth oil port 214 are connected to the servo pump station The oil return port of PS, the fifth oil port 215 is connected to the first oil port 811 of the first controller 810 and the first oil port 821 of the second controller 820 on the motor of the windlass W1, and the sixth oil port 216 is connected to the anchor The second oil port 812 of the first controller 810 and the second oil port 822 of the second controller 820 on the motor of machine W1.

Embodiment 2

[0036] refer to figure 2 In this embodiment, the working control system of the windlass windlass includes a servo pump station PS, five first direction switching valves, multiple second direction switching valves and multiple authority selection valve groups. The connection relationship and working principle of the servo pump station PS and the first direction switching valve are similar to the fifth embodiment above, the difference is that each second direction switching valve group and each authority selection valve group correspond to a winch or anchor machine.

[0037] Corresponding to the second direction switching valve 310 of windlass W1, the first oil port 311 and the second oil port 312 are connected to the oil outlet of the servo pump station PS, and the third oil port 313 and the fourth oil port 314 are connected to the servo pump station The oil return port of PS corresponds to the authority selection valve group of windlass W1, which includes a two-position six-...

Embodiment 3

[0049] refer to image 3 , the work control system of the anchor winch in this embodiment includes a servo pump station PS, 5 first direction switching valves, 5 second direction switching valves and 5 authority selection valve groups, and each authority selection valve group includes a two-position six-way reversing valve. Among them, the connection relationship and working principle of the servo pump station PS, the first direction switching valve, the second direction switching valve, and the two-position six-way switching valve are similar to those in the sixth embodiment above. The difference is that each authority selection valve group also includes The first sequence valve 902 , the first one-way valve 901 , the second sequence valve 904 and the second one-way valve 903 .

[0050] Fig. 7a is an enlarged schematic diagram of part M of the authority selection valve group provided by the embodiment shown in Fig. 7 . Referring to Figure 7a and in combination with Figure 7...

Abstract

The invention discloses a work control system of anchor and mooring machines, and belongs to the technical field of the anchor and mooring machines of a transportation ship. The work control system of the anchor and mooring machines comprises a servo pump station and a plurality of first direction switching valves, wherein the first direction switching valves correspond to all the anchor and mooring machines one to one, a first oil port and a second oil port of each first direction switching valve are connected with an oil outlet of the servo pump station, a third oil port and a fourth oil port of each first direction switching valve are connected with an oil return port of the servo pump station, a fifth oil port of each first direction switching valve is connected with a first oil port of a first controller and a first oil port of a second controller of a motor of the corresponding anchor and mooring machine, and a sixth oil port of each first direction switching valve is connected with a second oil port of the first controller and a second oil port of the second controller of the motor of the corresponding anchor and mooring machine. The work control system of the anchor and mooring machines only needs the first direction switching valves to control the anchor and mooring machines to work, is simple in structure, and is low in cost. In addition, the work control system of the anchor and mooring machines does not involve an electric part, and only involves the mechanical motions of the first direction switching valves, thereby being high in reliability.

Description

technical field [0001] The invention relates to the technical field of anchor winches for transport ships, in particular to a state control system for anchor winches. Background technique [0002] The anchor winch is an important deck equipment on a transport ship, which is related to the safety of the ship, so it needs to have high reliability, especially for large liquefied natural gas (LNG) carriers, the maneuverability of the anchor winch more demanding. There are many windlasses or winches scattered on the transport ship (the following windlasses or winches are collectively referred to as windlasses). On the transport ship, due to the large number of windlasses and scattered layouts, in order to expand the operator's sight of windlass operations , so that the operator can control the anchor winch more reliably. The existing anchor winch work control system generally uses local control plus remote centralized control to control the working state (forward or reverse) of ...
