It includes motor, reducing gear box and heaving pile reel, and the input shaft of reducing gear box is connected with the power take off of motor end, and a solenoid valve that can make the quick -witted circuit of stranded cable carry out the break -make is installed to the power input of the output shaft heaving pile reel of reducing gear box on the stranded cable machine, have a stopper of installing on the power input of heaving pile reel on the heaving pile reel, can make the stopper brake the heaving pile reel after the circuit disconnection of stranded cable machine. After adopting foretell structure, not only can protect the electromechanical quick -witted safety of stranded cable, can do not not burnt out with the electromechanical machine of protection stranded cable in the electromechanical source of automatic cutout stranded cable when the unexpected atress of hawser is too big, simultaneously, also can in time resume the power supply, it is out of control to be unlikely to ships and light boats, has avoided can't controing the great potential safety hazard that arouses because of ships and light boats, and its structural design is simple reasonable, can use widely in each ships and light boats army of the entire PLA, has good application prospect.

Description

Ships and light boats warping winch automaton

Technical field

The utility model relates to the control system that a kind of ships and light boats warping winch is used, specifically a kind of ships and light boats warping winch automaton.

Background technology

Ships and light boats are subject to distinguished and admirable impact in the process of pulling in to shore, and can produce drinking water and change, and cable is broken because of overload, and cable is lain in to the Mooring Arrangements on checking bollard, and management trouble, is prone to accidents, and can not meet the needs of. At present, ships and light boats army of land air force, except the canoes such as guard boat, comprises on polytype ships and light boats such as landing craft, cargo ship, towboat, tender and is all equipped with warping winch, and ships and light boats warping winch twists cable laying rope and uses while being mainly used in ships and light boats by leaving wharf. When ships and light boats alongside harbour, must first hawser be tied up on the checking bollard of harbour, then by the operation tension hawser of warping winch, and react on ships and light boats, be drawn in harbour side. Existing ships and light boats warping winch; in stranded cable process; may be because the external factor such as ships and light boats manipulation cause hawser suddenly stressed excessive; and then while causing warping winch to transship; for protection warping winch motor safety; in warping winch circuit, install fuse additional, its overload protection measure meeting automatic operation is not burnt with protection warping winch motor, and this automatic protected mode is substantially to cut off motor power as main. Although the method can be protected warping winch motor; but because warping winch power supply is now cut off; hawser is no longer stressed; cannot assist to control ships and light boats and handle action; may produce larger hidden danger to ships and light boats handling safety; therefore, the ships and light boats alongside safety guarantee based in such cases, is necessary a set of like this warping winch overload of development automatic adjustment system.

Summary of the invention

The technical problems to be solved in the utility model is to provide one not only can protect warping winch motor safety; can automatically cut off warping winch power supply when excessive and do not burnt with protection warping winch motor when hawser is suddenly stressed; simultaneously; also can restore electricity in time; be unlikely to ships and light boats out of control, avoided cannot handling because of ships and light boats the ships and light boats warping winch automaton of the larger potential safety hazard causing.

In order to solve the problems of the technologies described above, ships and light boats warping winch automaton of the present utility model, comprise motor, reduction box and warping barrel, the power shaft of reduction box is connected with the clutch end of motor, the output shaft of reduction box connects the power intake of warping barrel, a magnetic valve that can make the circuit of warping winch carry out break-make is installed on warping winch, on warping barrel, there is a brake on the power intake that is arranged on warping barrel; The circuit of warping winch can make brake brake warping barrel after disconnecting.

Adopt after above-mentioned structure, in the time warping winch circuit overloads being detected, circuit momentary interruption, avoid damage motor, now, warping winch runs out of steam, brake braking makes the rotational angular velocity of warping winch close to zero, then circuit path again, motor operation, the work of drive warping winch, meanwhile brake cuts out, monitors load again, if overload reruns said process one time, as do not transshipped, warping winch runs well, not only can protect thus warping winch motor safety, can automatically cut off warping winch power supply when excessive and do not burnt with protection warping winch motor when hawser is suddenly stressed, simultaneously, also can restore electricity in time, be unlikely to ships and light boats out of control, avoid cannot handling because of ships and light boats the larger potential safety hazard causing, its structural design advantages of simple, can promote the use of in each ships and light boats army of the entire PLA, have a good application prospect.

Fig. 2 is the flow chart of the utility model ships and light boats warping winch automaton.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, ships and light boats warping winch automatic control system of the present utility model is described in further detail.

As shown in Figure 1, ships and light boats warping winch automatic control system of the present utility model, comprise motor 2, reduction box 1 and warping barrel 3, the power shaft of reduction box 1 is connected with the clutch end of motor 2, the output shaft of reduction box 1 connects the power intake of warping barrel 3, a magnetic valve that can make the circuit of warping winch carry out break-make is installed on warping winch, on warping barrel 3, there is a brake on the power intake that is arranged on warping barrel; The momentary load when brake of installing is switched on warping winch is again unlikely to excessive, cause circuit breaker, use magnetic valve according to monitors load result, automatically open closed circuit, the circuit of warping winch can make brake brake warping barrel after disconnecting, by such structural design, can ensure ships and light boats be subject to 6 grades during with apparatus for lower wind effect (wind direction is perpendicular to hull center line) still can normally work.

Its operation principle is as follows:

As shown in Figure 2, in the time warping winch circuit overloads being detected, system makes circuit momentary interruption, effectively avoided damage motor, warping winch runs out of steam, after being pulled sky to turn around by hawser, brake starts braking makes the rotational angular velocity of warping winch close to zero, then circuit path again, motor operation, the work of drive warping winch, meanwhile brake cuts out, and monitors load again, if overload reruns said process one time, as do not transshipped, warping winch runs well.
