Particularly, this system also comprises: the first bi-bit bi-pass solenoid directional control valve 3 and the second bi-bit bi-pass solenoid directional control valve 5, the oil inlet P 3 of the first bi-bit bi-pass solenoid directional control valve 3 is communicated with the oil outlet A2 of hand change over valve 2, the oil outlet A3 of the first bi-bit bi-pass solenoid directional control valve 3 is communicated with the oil inlet P 4 of two position, three-way electromagnetic change valve 4, the oil inlet P 5 of the second bi-bit bi-pass solenoid directional control valve 5 is communicated with the oil inlet P 2 of hand change over valve 2 with the oil outlet A1 of the first check valve 1 respectively, the oil outlet A5 of the second bi-bit bi-pass solenoid directional control valve 5 is communicated with the oil inlet P 4 of two position, three-way electromagnetic change valve 4 with the oil outlet A3 of the first bi-bit bi-pass solenoid directional control valve 3 respectively.
Particularly, when the first bi-bit bi-pass solenoid directional control valve 3 is not energized, oil inlet P 3 is communicated with oil outlet A3, and after energising, oil inlet P3 is not communicated with oil outlet A3; When second bi-bit bi-pass solenoid directional control valve 5 is not energized, oil inlet P 5 is not communicated with oil outlet A5, and after energising, oil inlet P5 is communicated with oil outlet A5.Windlass casts anchor speed control system when normally working, the first bi-bit bi-pass solenoid directional control valve 3 and the second bi-bit bi-pass solenoid directional control valve 5 no power.
In actual applications, if do not want to come hydraulic ram 9 injection liquid force feed by hand change over valve 2, can adopt and make the method for the first bi-bit bi-pass solenoid directional control valve 3 and the energising of the second bi-bit bi-pass solenoid directional control valve 5 to realize same function simultaneously.Particularly, hand change over valve 2 is switched to right position mode of operation and two position, three-way electromagnetic change valve 4 no energising, the hydraulic oil entered by system oil inlet can enter in hydraulic ram 9 along the circuit of P-P1-A1-P2-A2-P4-A4-P8-A8-P9; If the first bi-bit bi-pass solenoid directional control valve 3 and the second bi-bit bi-pass solenoid directional control valve 5 are energized simultaneously, now, two position, three-way electromagnetic change valve 4 is energising no, the hydraulic oil entered by system oil inlet can be entered in hydraulic ram 9 along the circuit of P-P1-A1-P5-A5-P4-A4-P8-A8-P9, completes the work to compressing cylinder 9 injection liquid force feed.

Particularly, the pressure that by pass valve 6 sets is less than the pressure that windlass is in hydraulic oil when freely casting anchor state in hydraulic ram 9.Wherein, windlass is in the freely state of casting anchor and refers to that stop mechanism 10 does not provide the state of casting anchor when braking restriction to windlass.
In actual applications, the excessive velocities of casting anchor that can prevent windlass is set like this.Particularly, when windlass cast anchor excessive velocities time, two position, three-way electromagnetic change valve 4 can be energized, to be switched to right position mode of operation.The pressure set due to by pass valve 6 is less than windlass and is in the pressure of hydraulic oil when freely casting anchor state in hydraulic ram 9, section hydraulic oil in hydraulic ram 9 can flow into the return opening of system along the circuit of P9-A8-P8-A4-T4-P6-A6-T, the pressure that the pressure of the hydraulic oil in hydraulic ram 9 and by pass valve 6 are set is consistent, this pressure can only ensure that application force that hydraulic ram 9 is supplied to stop mechanism 10 opens the part brake restriction of stop mechanism 10 pairs of windlass, makes windlass be in half braking state.Owing to there is the effect of a part of brake weight, the speed of casting anchor can progressively reduce.
In actual applications, the pressure that by pass valve 6 sets can be 1.2MPa.Above-mentioned numerical value is only citing, and conduct is not to restriction of the present utility model, and the setting of pressure value can also carry out selection setting according to actual conditions.
The principle of work of oil cylinder hydraulic brake system is sketched below in conjunction with Fig. 1 and Fig. 2:
In Fig. 1, the oil outlet A7 of the second check valve 7 is communicated with the oil outlet A3 of the first bi-bit bi-pass solenoid directional control valve 3 with the oil inlet P 4 of two position, three-way electromagnetic change valve 4 respectively.
Under conventional sense, hand change over valve 2 is in left position mode of operation, two position, three-way electromagnetic change valve 4, first bi-bit bi-pass solenoid directional control valve 3 and the second bi-bit bi-pass solenoid directional control valve 5 all do not have energising, hydraulic oil in hydraulic ram 9 flows into the return opening of system under the effect of spring 94 along the circuit of P9-A8-P8-A4-P4-A3-P3-A2-T2-T, hydraulic ram 9 is in contraction state, push rod 95 provides application force to stop mechanism 10, make stop mechanism 10 be in complete braking state, windlass cannot action.
When windlass prepares to start to cast anchor, manually hand change over valve 2 is switched to the work of right position, now, two position, three-way electromagnetic change valve 4, first bi-bit bi-pass solenoid directional control valve 3 and the second bi-bit bi-pass solenoid directional control valve 5 all do not have energising, and the hydraulic oil entered by system oil inlet can enter hydraulic ram 9 along the circuit of P-P1-A1-P2-A2-P3-A3-P4-A4-P8-A8-P9.When injection liquid force feed reaches a certain amount of, hydraulic oil can promote piston 92, the effect making piston 92 overcome spring 94 is moved to the second cavity 93 direction, push rod 95 also setting in motion under the drive of piston 92, and provide application force for stop mechanism 10, stop mechanism 10 is opened limit the brake of windlass, until windlass is in open braking state completely, and then make windlass can start freely to cast anchor.
When windlass prepares to start to cast anchor, the method that the first bi-bit bi-pass solenoid directional control valve 3 and the second bi-bit bi-pass solenoid directional control valve 5 are energized simultaneously can also be adopted.Now, manually hand change over valve 2 is in the work of left position, two position, three-way electromagnetic change valve 4 is energising not, and the hydraulic oil entered by system oil inlet can be entered in hydraulic ram 9 along the circuit of P-P1-A1-P5-A5-P4-A4-P8-A8-P9, makes windlass prepare to start to cast anchor.Specific works process illustrates above, is not repeating here.
After windlass starts to cast anchor, if cast anchor excessive velocities, more than the first setting speed (size of this speed can select setting according to the actual requirements), two position, three-way electromagnetic change valve 4 can be energized, to be switched to right position mode of operation.The pressure set due to by pass valve 6 is less than windlass and is in the pressure (1.2MPa is less than 2.1MPa) of hydraulic oil when freely casting anchor state in hydraulic ram 9, section hydraulic oil in hydraulic ram 9 can flow into the return opening of system along the circuit of P9-A8-P8-A4-T4-P6-A6-T, the pressure that the pressure of the hydraulic oil in hydraulic ram 9 and by pass valve 6 are set is consistent (namely remaining on 1.2MPa), this pressure can only ensure that application force that hydraulic ram 9 is supplied to stop mechanism 10 opens the part brake restriction of stop mechanism 10 pairs of windlass, windlass is made to be in half braking state.Owing to there is the effect of a part of brake weight, the speed of casting anchor can reduce.
After windlass starts to cast anchor, if think emergency brake, hand change over valve 2 can be switched to left position mode of operation.Now, two position, three-way electromagnetic change valve 4, first bi-bit bi-pass solenoid directional control valve 3 and the second bi-bit bi-pass solenoid directional control valve 5 all do not have energising, the hydraulic oil be in hydraulic ram 9 can flow into the return opening of system along the circuit of P9-A8-P8-A4-P4-A3-P3-A2-T2-T, along with the pressure of the fluid oil in hydraulic ram 9 declines gradually, the brake weight of stop mechanism 10 pairs of windlass can be increasing, until windlass is in complete braking state.
Cast anchor in process at windlass, because the hydraulic oil in hydraulic ram 9 can leak into the reason of the second cavity 93 from the first cavity 91 by piston 92, the pressure of the hydraulic oil of hydraulic ram 9 can decline gradually, and the brake weight that stop mechanism 10 is provided is increasing, and the speed goes that casts anchor is slow.When the speed of casting anchor is lower than the second setting speed (size of this speed can select setting according to the actual requirements), two position, three-way electromagnetic change valve 4 power-off is to switch back left position mode of operation, the hydraulic oil entered by system oil inlet just can be supplemented and enter oil cylinder 9, to recover the application force of hydraulic ram 9 pairs of stop mechanisms 10, the brake weight of stop mechanism 10 pairs of windlass is reduced, and then increases the speed of casting anchor of windlass.
From the above, windlass cast anchor speed control system define a closed loop control system (namely hydraulic oil windlass cast anchor speed control system Inner eycle utilize), and this system reaches dynamical equilibrium, namely windlass windlass cast anchor speed control system effect under the most of the time be in half braking state, the speed of casting anchor of windlass maintains between the first setting speed and the second setting speed.So just can realize automatically regulating windlass speed of casting anchor, by the speeds control that casts anchor in certain scope, in order to avoid anchor chain descending speed too fast and stop suddenly time the enormous impact power damage that windlass itself or deck in ship structure are caused that produces.
In addition, in actual applications, the oil outlet A7 of the second check valve 7 can also be communicated with the oil inlet P 3 of the first bi-bit bi-pass solenoid directional control valve 3 with the oil outlet A2 of hand change over valve 2 respectively, when emergency brake thought by windlass, hand change over valve 2 can be switched to left position mode of operation, now, two position, three-way electromagnetic change valve 4, first bi-bit bi-pass solenoid directional control valve 3 and the second bi-bit bi-pass solenoid directional control valve 5 all do not have energising, and the hydraulic oil be in hydraulic ram 9 can flow into the return opening of system along the circuit of P9-A8-P8-A4-P4-A2-T2-T.Other principle of work of this mode of communicating are identical with above-mentioned principle, do not repeating here.
The utility model forms windlass by hydraulic ram, stop mechanism, the first check valve, hand change over valve, two position, three-way electromagnetic change valve, by pass valve and one-way throttle valve and to cast anchor speed control system, when windlass casts anchor excessive velocities, regulate two position, three-way electromagnetic change valve that hydraulic ram is communicated with by pass valve, the brake weight of stop mechanism to windlass is increased, with the speed of casting anchor of the windlass that slows down by the pressure of hydraulic oil in regulator solution compressing cylinder; When the speed of casting anchor of windlass is crossed slow, by two position, three-way electromagnetic change valve, the oil inlet of system is communicated with hydraulic ram, reduces the brake weight of stop mechanism to windlass by the hydraulic oil in replenisher compressing cylinder, to increase the speed of casting anchor of windlass.So both can prevent from anchor chain from exceeding the speed limit under self gravitation effect decline and damage windlass or deck in ship structure, the efficiency of casting anchor of windlass can have been ensured again; In addition, this system architecture is simple, and reliability is high, less demanding to operating personal, convenient operation librarian use.
