Detailed Description
For the purpose of enhancing the understanding of the present invention, the present invention will be further described in detail with reference to the following examples and the accompanying drawings, which are only used for explaining the present invention and are not to be construed as limiting the scope of the present invention.
As shown in fig. 1-2, the gravity lowering control system of the boat lifting device comprises a pump station 1, a multi-way valve 2, a console 3, a hydraulic winch 4, an energy accumulator 5, an oil cylinder 6, a bracket 7, a binding device 8, a pressure gauge 9, a stop valve iii 10, a stop valve ii 11, an overflow valve 12, a check valve 13, a stop valve i 14, a brake 15, a hydraulic reversing valve 16, a throttle valve 17, a shuttle valve 18 and a pressure reducing valve 19.
The pump station 1 provides power sources for the retraction and release of a hydraulic winch 4, the pressurization of an energy accumulator 5 and the expansion and contraction of an oil cylinder 6 of the boat lifting device. The directions of the two actions are controlled by a multi-way valve 2 arranged on an operating platform 3 through the direction of a hydraulic handle, and the speeds of the two actions are controlled by the opening size of the hydraulic handle of the multi-way valve 2. When the boat sling is in an initial storage state, the boat is stored on the boat sling bracket 7 and is fixed by the binding device 8 so as to prevent the boat from being damaged by collision and friction when the ship runs. At this time, the piston rod of the oil cylinder 6 is in a retracted position, and the steel wire rope of the hydraulic winch 4 is also in an unloading state. When the boat needs to be released, the binding device 8 is firstly opened, all obstacles are removed, then the power supply is switched on, the hydraulic pump station 1 is started, and the pump station 1 supplies hydraulic oil with certain pressure and flow to the hydraulic system. Then the handle of the oil cylinder 6 of the multi-way valve 2 arranged on the control console 3 is pushed forwards, the piston rod of the oil cylinder 6 extends out, and the boat lifting device connected with the boat is turned out. And then, a handle of a hydraulic winch 4 of the multi-way valve 2 arranged on the control console 3 is pushed forwards, the hydraulic winch 4 rotates reversely, and the boat is lowered to the water surface, so that the boat releasing process is completed. When the boat lifting device is used each time, whether the pressure of hydraulic oil in the energy accumulator 5 is within a required range or not needs to be checked, and preparation is made for using the gravity of the energy accumulator 5 to lower the boat in an emergency. If the pressure of the hydraulic oil in the energy accumulator 5 is lower than the required value, the hydraulic oil is supplemented to the energy accumulator 5 (hereinafter referred to as charging), namely the hydraulic pump station 1 is started, and the handle of the oil cylinder 6 of the multi-way valve 2 is pulled backwards to charge the energy accumulator 5. When the ship is in an emergency condition of power loss, the energy accumulator 5 filled with hydraulic oil in advance serves as a power source, the hydraulic oil in the energy accumulator 5 firstly enters a rodless cavity of the oil cylinder 6, the boat lifting device connected with the boat is turned out of the ship, then the hydraulic winch 4 is started, the brake 15 of the hydraulic winch 4 is opened, the hydraulic winch 4 is in a floating state, the hydraulic winch 4 rotates reversely under the self weight of the boat, and the boat falls to the water surface.
When the accumulator 5 needs to be charged, firstly, the power supply is switched on, the hydraulic pump station 1 is started, then the handle of the oil cylinder 6 of the multi-way valve 2 is pulled backwards, and hydraulic oil enters the rod cavity of the oil cylinder 6 from the port B1 and simultaneously enters the accumulator 5 through the one-way valve 13. The hydraulic oil entering the rod cavity of the oil cylinder 6 retracts the piston rod of the oil cylinder 6, and when the piston rod retracts to the right position, the hydraulic oil flows into the energy accumulator 5 completely to charge the energy accumulator 5. The check valve 13 only allows hydraulic oil to enter the energy accumulator 5, and is stopped reversely, so that the hydraulic oil in the energy accumulator 5 is prevented from flowing back, and pressure is maintained for the energy accumulator 5. The pressure of the hydraulic oil in the energy accumulator 5 can be checked through a pressure gauge 9 arranged on the energy accumulator 5, when the pressure of the hydraulic oil in the energy accumulator 5 reaches a required value and the operator continues to perform the pressurizing misoperation, the overflow valve 12 overflows the redundant hydraulic oil to the oil tank at the moment so as to prevent the hydraulic system from being damaged by high pressure. The set value of the relief valve 12 may be adjusted according to the specific value of the charging pressure of the accumulator 5, and is generally set to +1 of the charging pressure of the accumulator 5. If the energy accumulator 5 needs to be overhauled, the pressure oil in the energy accumulator 5 is discharged firstly, the pressure oil cannot be overhauled under pressure, and the stop valve II 11 is the oil drainage stop valve for overhauling the energy accumulator 5.
Under the condition of power loss, the stop valve III 10 is opened firstly, then the handle of the oil cylinder 6 of the multi-way valve 2 arranged on the control console 3 is pushed forwards, hydraulic oil in the energy accumulator 5 enters a rodless cavity of the oil cylinder 6, and a piston rod of the oil cylinder 6 extends out to drive the boat lifting device connected with a boat to rotate out of a board. Then the stop valve I14 is opened, and the hydraulic oil in the energy accumulator 5 enters the hydraulic winch 4. The hydraulic oil acts on the hydraulic reversing valve 16, the hydraulic reversing valve 16 is reversed, the AB ports of the hydraulic winch 4 are communicated through the throttle valve 17, meanwhile, the brake 15 is opened through the shuttle valve 18 by the hydraulic oil, the hydraulic winch 4 is in a floating state, and the hydraulic winch 4 rotates reversely to lower the boat under the action of the self weight of the boat. At this time, the hydraulic oil in the hydraulic winch 4 flows into the hydraulic winch 4 again through the port B, the throttle valve 17, the hydraulic reversing valve 16 and the port A, and circulation is achieved. However, because of leakage of hydraulic winch 4, less and less hydraulic oil circulates, and accumulator 5 is needed to replenish hydraulic winch 4 with oil. The accumulator 5 supplies oil to the hydraulic winch 4 through the pressure reducing valve 19, and the hydraulic winch 4 is prevented from being damaged due to air suction. When the boat is transferred by the gravity of the hydraulic winch 4, the throttle valve 17 plays a role in back pressure, so that the boat is prevented from being dangerous due to the fact that the releasing speed of the boat is too high.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
