Detailed Description
In order that the above objects, features and advantages of the present application can be more clearly understood, the present application will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, the present application may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited by the specific embodiments disclosed below.
As shown in fig. 1 and 2, the present embodiment provides a multifunctional lifting winch for manned submersible recovery operation, which includes a lifting winch assembly 103, a speed reducer 108, a hydraulic motor 109, and a hydraulic control system, wherein the speed reducer 108 and the hydraulic motor 109 connected in sequence are disposed at two ends of the lifting winch assembly 103, and the hydraulic motor 109 is connected to a first pipeline and a second pipeline of the hydraulic control system.
Specifically, the bracket 101 is mounted on a stern deck of a working mother ship on which a man-riding submersible 107 is mounted, the bracket 101 swings by a luffing cylinder 102 at the rear side thereof, the lifting winch assembly 103 is mounted on a swing hanger 104, and the swing hanger 104 is connected to a cross beam of the bracket 101 by an anti-swing device 106 to reduce the swing of the lifting winch assembly 103. A main hoist cable 105 is wound around a drum of the hoisting winch assembly 103, and a connection end of the main hoist cable 105 passes through the swing hanger 104, so that the manned submersible 107 can be hoisted by controlling the rotation of the drum.
In the laying and recovery operation of the manned submersible vehicle 107, the luffing cylinder 102 is driven by a conventional electric control system, so that the bracket 101 is swung to an outboard or inboard operating point, the lifting winch 103 is driven to receive and release the main hoisting cable 105 to hoist the manned submersible vehicle 107, and the anti-swing device 106 is used for realizing the state stabilization of the manned submersible vehicle 107 in the transfer process.
However, as the manned submersible 107 is often subjected to the combined effects of wind and wave currents during deployment and recovery, the manned submersible 107 and the mother ship have relatively large amplitude relative movements. In particular, during recovery, the cables tend to have a large impact load during the release of the submersible vehicle 107 from the sea, and therefore constant tension pretensioning of the cables in the hoisting winch is required to ensure equipment safety of the submersible vehicle 107.
In this embodiment, on the basis of a conventional electronic control system, a hydraulic control system is provided to adjust the flow rate of the hydraulic oil flowing into the hydraulic motor 109, so as to control the hoisting winch 103 and realize constant tension pre-tightening of the cable. The hydraulic control system includes: a winch control valve block 200 and an accumulator valve block 300; the winch control valve group 200 comprises an electromagnetic valve 201, a balance valve 202 and a proportional overflow valve 203, the output end of the electromagnetic valve 201 is connected to the first pipeline and the second pipeline respectively, the input end of the electromagnetic valve 201 is connected to the pressure oil pipeline P and the oil return pipeline T respectively, the electromagnetic valve 201 is used for adjusting the conduction state between the input end and the output end, and the winch control valve group 200 is used for controlling the direction and the flow of hydraulic oil flowing into the hydraulic motor 109.
Specifically, the conduction states of the solenoid valve 201 include two, and the first conduction state is: the pressure oil pipe P is communicated with the second pipe, the oil return pipe T is communicated with the first pipe, at this time, the hydraulic oil in the pressure oil pipe P flows into the port a of the hydraulic motor 109 through the second pipe, the hydraulic oil in the first pipe flows into the oil return pipe T, and the hydraulic motor performs cable retracting movement.
The second on state is: the pressure oil pipeline P is communicated with the first pipeline, the oil return pipeline T is communicated with the second pipeline, at this time, hydraulic oil in the pressure oil pipeline P flows into the port B of the hydraulic motor 109 through the first pipeline, hydraulic oil in the second pipeline flows into the oil return pipeline T, and the hydraulic motor makes cable laying movement.
In this embodiment, the balancing valve 202 is connected in series with the second pipeline, the pilot control valve of the balancing valve 202 is connected to the first pipeline, and the balancing valve 202 is used for forming a controlled flow resistance in the second pipeline to balance the weight of the load (the manned vehicle 107) when the lifting winch assembly 103 releases the main hoist cable 105, i.e. in the cable releasing condition, so as to prevent the hydraulic motor 109 from moving out of control or instability, and the balancing valve 202 is fully opened in the cable releasing condition so as to open the oil path.
In this embodiment, the proportional relief valve 203 is connected in parallel between the first pipeline and the second pipeline, and the proportional relief valve 203 is configured to dynamically adjust a relief pressure value between the second pipeline and the hydraulic motor 109 to limit a highest pressure of the a-port pipeline of the hydraulic motor 109, so as to implement constant tension control and pressure limiting protection.
Specifically, proportional relief valve 203 includes a pressure range of two gears, and the first gear is set to be a low gear pressure, such as 50-170 bar, and the second gear is set to be a high gear pressure, such as 250 bar.
When the submersible is normally lifted, the pressure set value of the proportional relief valve 203 is high-grade pressure. After the manned submersible 107 is cabled, when the constant tension cable is tightened, the proportional relief valve 203 is lowered to a low-level pressure.
By arranging the proportional relief valve 203, the overflow amount of the proportional relief valve 203 can be controlled by using a conventional electric control program and combining the gear set by the proportional relief valve 203 and the cable tension. On one hand, the overflow amount can be automatically adjusted within a selected gear range according to the sea condition or the use experience of the site.
On the other hand, the device can also be combined with a cable tension sensor or a hydraulic pressure sensor, and the overflow amount is adjusted in real time by utilizing a conventional closed-loop feedback algorithm in a gear range so as to ensure that the cable tension of the main suspension cable 105 is in a preset range, meet the cable tensioning requirement of the manned submersible vehicle 107 under different sea conditions, tighten the constant tension of the cable and ensure the equipment safety of the manned submersible vehicle 107 in the recovery process.
The conventional electric control system is utilized to carry out the operation of the lifting winch, when the lifting winch 103 is normally retracted and extended, the proportional overflow valve 203 is firstly configured to be high-grade pressure, and the displacement of the hydraulic motor is configured to be the maximum displacement. The conducting state of the electromagnetic valve 201 is adjusted through a conventional electric control system to supply oil to the hydraulic motor in different directions, and the hydraulic motor is controlled to rotate in the forward direction or the reverse direction, namely the winch 103 is lifted to release or retract cables.
If the solenoid valve 201 is configured in the first conducting state (cable releasing), the pressure oil line P is communicated with the first line, the oil return line T is communicated with the second line, and the hydraulic oil enters the port B of the hydraulic motor through the first line. At the same time, the hydraulic oil in the first line also enters the normally closed spring brake 503 via the throttle 502 of the shuttle valve 501, opening it. At this time, the conventional electronic control system controls the hydraulic motor to drive the speed reducer 108 to move, so that the hoisting winch 103 can stably unwind the cable.
If the solenoid valve 201 is configured to be in the second conduction state (cable retracting), at this time, the pressure oil pipeline P is communicated with the second pipeline, the oil return pipeline T is communicated with the first pipeline, and the hydraulic oil flows into the second pipeline through the bypass check valves arranged at the two ends of the balance valve 202 and enters the port a of the hydraulic motor, so that the oil circuit is smooth under the cable retracting working condition. At this time, the conventional electronic control system controls the hydraulic motor to drive the speed reducer 108 to move, so that the cable is stably wound on the hoisting winch 103.
When the system (lifting winch 103) is in the submersible recovery state, the proportional relief valve 203 is configured to a low range pressure, and the displacement of the hydraulic motor is configured to a smaller displacement, such as 15% to 25% displacement, which combined setting provides the high speed, low load condition requirements required for constant tension.
Further, when the system is in the submarine recovery state and it is determined that the cable tension is large, the proportional relief valve 203 is configured to be in the first gear (low-gear pressure), so that the hydraulic oil in the pressure oil line P flowing into the hydraulic motor 109 through the second line overflows from an overflow port of the proportional relief valve 203 at a predetermined flow rate (overflow amount), wherein the predetermined flow rate is determined by the pressure range corresponding to the first gear and the cable tension.
In particular, a tension sensor may be provided on an existing cable to detect cable tension. In the recovery state of the submersible, if the cable tension is too high, the hydraulic motor is required to run reversely, namely, the cable is converted from cable collection to cable discharge, and since the proportional overflow valve 203 is configured to be in the first gear and the tension of the external cable is too high, the cable is automatically dragged backwards and the hydraulic motor 109 is caused to run reversely. The tension sensor is arranged on the cable, the tension of the cable is introduced in real time, the set value of the proportional overflow valve 203 is finely adjusted in a closed loop mode, and the constant tension of the cable is accurately controlled.
Hydraulic oil between the port A of the hydraulic motor and the balance valve 202 flows out through the proportional overflow valve 203, the winch is lifted to quickly release the cable until the tension is reduced to a required range, and meanwhile the accumulator 303 supplies oil to the port B of the hydraulic motor to prevent the motor from being damaged due to air suction.
In this embodiment, the accumulator valve block 300 is used for supplementing oil to the first pipeline and the second pipeline, wherein the accumulator valve block 300 includes: a pressure reducing valve 301, a sequence valve 302 and two accumulators 303 arranged in parallel; one end of the pressure reducing valve 301 is connected to an oil supplementing pipeline S of the system, the other end of the pressure reducing valve 301 is connected to an oil inlet end of the sequence valve 302, the sequence valve 302 is used for supplementing oil to the accumulator 303 in an under-pressure state, and the under-pressure state of the accumulator 303 can be determined by measuring the pressure in the accumulator 303 through a pressure sensor arranged in the accumulator 303.
The outlet end of the sequence valve 302 is connected to an accumulator 303 provided in parallel, and the accumulator 303 is connected to one end of the hydraulic motor 109 after being connected to a check valve 305 and a stop valve 304 in series in this order.
Specifically, the oil supplementing pipeline S continuously supplements oil for the energy accumulator 303 through the pressure reducing valve 301 and the sequence valve 302 to ensure that the energy accumulator 303 is in an available state at any time, and the energy accumulator 303 and the check valve 305 supplement oil for the first and second pipelines (the pipelines between the hydraulic motor and the balance valve 202) to reduce the influence caused by leakage and suction of the hydraulic motor and ensure that the load (the hoisting winch 103) is controlled and stable. The shut-off valve 304 is only used to isolate the accumulator 303.
Further, the system further comprises: a normally closed spring brake 503, a throttle valve 502, and a shuttle valve 501; a normally closed type spring brake 503 is connected in series between the speed reducer 108 and the hydraulic motor 109, and the control end of the normally closed type spring brake 503 is connected to the output end of the shuttle valve 501 through a throttle valve 502; the shuttle valve 501 is connected in parallel between the first and second lines.
Specifically, a normally closed spring brake 503 is used as a brake device of the hydraulic motor 109, and forms a brake circuit together with the throttle valve 502 and the shuttle valve 501. When the winch performs the reversing operation of receiving/releasing, pressure oil in the pressure oil pipeline P is introduced into the brake loop, so that the brake opening function is ensured to be available.
When the manned submersible vehicle 107 is recovered, after the cable (the main suspension cable 105) is hung by a frogman and the manned submersible vehicle 107, the cable is in a loose and tensioning alternate state under the influence of wind waves in the stage before the manned submersible vehicle 107 goes out of water, and at the moment, the constant tension tightening operation of the cable is carried out, so that the cable is prevented from being broken due to huge impact caused by direct hoisting, and the possibility of damaging equipment of the manned submersible vehicle 107 exists. After the constant tension of the mooring rope is tightened, when the manned submersible 107 and the mother ship are influenced by sea waves and move relatively greatly, the winch (the hoisting winch assembly 103) can realize rapid retraction and release actions under the action of the proportional overflow valve 203 at a low gear, and the constant tension of the mooring rope is maintained along with the relative movement of the two. For example, when manned submersible 107 is pushed up by ocean waves, the cable is slack and the tension is reduced, the winch can quickly tighten the cable; when the manned submersible 107 descends along with sea waves and the cable is tight and the tension is suddenly increased, the winch can quickly release the cable, so that the tension of the cable is kept stable, and the cable is prevented from breaking.
The proportional relief valve 203 is in the low gear position, and the hydraulic motor 109 is simultaneously set to the low displacement. When the hydraulic motor 109 is in low discharge capacity, the rotating speed of the motor can be greatly increased by hydraulic oil with the same flow, and the response capability of the winch is improved when the high-speed cable winding and unwinding is realized. Meanwhile, after the proportional overflow valve 203 is in a low gear, the lifting force of the mooring rope becomes low, only is 1/5-1/8 normal, and the mooring rope can be tightened but the submersible cannot be lifted away from the water surface. When the submersible descends, the tension of the cable is increased, the hydraulic motor 109 stops cable winding and reversely rotates to passively release the cable under the action of external load tension, the pressure in the second pipeline exceeds the gear setting of the proportional overflow valve 203, and oil brought by the reverse rotation of the hydraulic motor 109 overflows through the proportional overflow valve 203, so that the tension is kept stable during cable releasing of the cable.
When deploying the manned submersible 107, the proportional relief valve 203 is kept at the high-range pressure, and the hydraulic motor 109 is simultaneously set to the high displacement, so that the cable is slowly lowered.
Further, at manned submersible retraction work's in-process, the hoist winch trouble that probably takes place, at this moment, in order to guarantee manned submersible's equipment safety and personnel's safety, need carry out emergent the retrieving to manned submersible, consequently, should promote the winch and include two sets of hydraulic control system, the symmetry sets up in hydraulic motor 109's both sides, hydraulic control system still includes the emergent operation valves 400 that two sets of symmetries set up, emergent operation valves 400 includes: four longitudinal shut-off valves 401 and one transverse shut-off valve 402; the transverse shutoff valve 402 is connected in parallel between the first pipeline and the second pipeline; two liang of back of establishing ties of four vertical stop valves 401 are established ties in first pipeline and second pipeline respectively, are connected with first emergent pipeline 403 between two vertical stop valves 401 of establishing ties in first pipeline in two sets of emergent operating valves 400, are connected with second emergent pipeline 404 between two vertical stop valves 401 of establishing ties in the second pipeline in two sets of emergent operating valves 400.
Specifically, in order to deal with the problem that the hydraulic motor on one side of the hoisting winch and the winch control valve group 200 fail accidentally to cause the fault of the hoisting winch 103 and realize the emergency recovery operation of the manned submersible, an emergency operation valve group 400 is introduced into the system, at the moment, the system comprises two groups of symmetrically arranged hydraulic control systems and two groups of symmetrically arranged emergency operation valve groups 400, wherein the emergency operation valve group 400 is connected in series between a first pipeline and a second pipeline.
When the single-side winch control valve group fails, after the failure winch control valve group is determined, the two lower parts of the four longitudinal stop valves connected in series on the failure valve group side are closed, the failure winch control valve group is isolated from the hydraulic motor, and the hydraulic motor is supplied with hydraulic oil through the winch control valve group on the other side, so that the full-function operation of the hoisting winch is realized. At this time, it should be noted that, considering the valve bank and the pipeline overflow capacity, the maximum hoisting speed of the winch should be reduced to 50% -70%.
