Abstract

The utility model discloses a hydraulic energy-storing emergency device and a field movable boarding ladder using the same. The hydraulic energy-storing emergency device is characterized by consisting of a hydraulic energy-storing device (1), a pressure relay (2), a one-way valve (3) and an electromagnetic change valve or a combination valve set (4), wherein an oil path between a pump end (P) and the energy-storing device (1) is provided with the one-way valve (3); the installation direction of the one-way valve allows the liquid-charging oil flow to unidirectionally pass from the pump end (P) to the energy-storing device; the pressure relay (2) is connected with an oil path which is directly communicated with the energy-storing device; and the electromagnetic change valve or a combination valve set (4) is connected between the energy-storing device and a load end (L). The hydraulic energy-storing emergency device can provide the stored hydraulic energy to a prime motor which needs emergency action when stopping working; and the field movable boarding ladder using the hydraulic energy-storing emergency device can complete the emergency action running away from the cabin when stopping working.

Description

A kind of hydraulic energy-accumulating emergency device and use the portable boarding ladder in place of this device
Technical field
The equipment that the present invention relates to stop prime mover work but still can make emergency reaction has especially referred to use the portable boarding ladder in place of accumulation of energy emergency device.
Background technique
Upper and lower visitor such as roll-on-roll-off ship uses a kind of boarding ladder that has from the mechanism of walking, and becomes the portable boarding ladder in place.After ladder hangs up hatch door, motor is turned off, not only energy-conservation but also can avoid the passenger of waste gas and the upper and lower ship of noise effect, but must when the appearance of accidents such as Dragging, make boarding ladder break away from ship, this just must provide energy to come execution.
Summary of the invention
The invention provides a kind of hydraulic energy-accumulating emergency device, it is characterized in that, this emergency device is by hydraulic accumulator (1), pressure relay (2), one-way valve (3) and solenoid directional control valve or combination valve group (4) constitute, on the oil circuit between pump end (P) and the accumulator (1) one-way valve (3) is installed, its installation direction allows pump end (P) to unidirectional the passing through of accumulator topping up oil stream, on the oil circuit that pressure relay (2) is connected with accumulator directly communicates, solenoid directional control valve or combination valve group (4) are connected between accumulator and the load end (L).
Described hydraulic energy-accumulating emergency device is characterized in that, its electromagnetic switch combination valve group (4) is made up of with the Pilot operated check valve that this valve is controlled a guide's Solenoid ball valve (4.1).
The portable boarding ladder in described a kind of place is characterized in that this equipment adopts above-mentioned hydraulic energy-accumulating emergency device.
In this programme, the hydraulic energy-accumulating emergency device is prime mover when needing emergency action when quitting work, and the hydraulic pressure energy of storage is provided; And the portable boarding ladder in the place of using the hydraulic energy-accumulating emergency device can be finished the action of emergent disengaging cabin when shutting down.
Description of drawings
Fig. 1 is a hydraulic schematic diagram of the present utility model;
Fig. 2 is another hydraulic schematic diagram of the present utility model.
Embodiment
In order to describe implementation methods of the present utility model in detail, see accompanying drawing 1.
This is the hydraulic principle schematic representation of the hydraulic energy-accumulating emergency device of an example.
This installs by hydraulic accumulator (1), pressure relay (2), and one-way valve (3) and solenoid directional control valve or combination valve group (4) constitute.One-way valve (3) P end links to each other with pumping source, and solenoid directional control valve is located cut-off state usually, and it has completely cut off the pressure of accumulator and load end (L).Before prime mover stall, pumping source fills pressure oil by one-way valve (3) to hydraulic accumulator (1), and when treating that pressure rises to setting value, pressure relay (2) sender makes control system stop pumping source to the accumulator topping up.At this moment, if be necessary to make prime mover to quit work.Solenoid directional control valve and one-way valve make accumulator be in packing state.Solenoid directional control valve is optional with the leakage rate of Solenoid ball valve when reducing packing state.When leakage causes accumulator place pressure to descend, can make prime mover start the fluid infusion of rear driving oil hydraulic pump, the pressure of accumulator is maintained in the scope of setting all the time.
When packing state, when the situation that occurs meeting an urgent need, send instruction by controller, make solenoid directional control valve change conducting into by ending.The pressure oil of accumulator is just emergent to the load end fuel feeding by solenoid directional control valve like this.
Above-mentioned combination valve group can be that the main valve of a pilot valve and pilot valve control constitutes.The through-current capacity of main valve is more greatly to satisfy actual demand.
Indicated in the accompanying drawing 2 also is the schematic diagram of a hydraulic energy-accumulating emergency device, and its electromagnetic switch combination valve group is made up of with the Pilot operated check valve (4.2) of this valve control a guide's Solenoid ball valve (4.1).Through-flow the reaching by and dead electricity electric by getting of this valve coil of this Solenoid ball valve realized state exchange.
For example when electric, this Solenoid ball valve is through-flow, makes the pressure oil of accumulator supply with Pilot operated check valve as pilot pressure oil, and it is opened, and makes pressure oil that accumulator is store by this valve passing through of big flow be arranged, confession load emergency.When dead electricity, this Solenoid ball valve ends, and the pilot pressure oil of supplying with Pilot operated check valve is because by the rapid pressure release of this valve earial drainage, Pilot operated check valve is closed rapidly and owing to be one-way valve, has minimum leakage rate, and pressurize is very effective during to the accumulator topping up.Pressurize when so just having satisfied topping up, the function of voltage supply when emergent.
Use the portable boarding ladder in place of above-mentioned accumulation of energy emergency device, when ladder with after cabin docks, ladder must together drift with ripple with ship, drifts in certain scope but must monitor it.When ship owing to during accident (for example dragging of anchor), can cause ladder to drift and exceed normal range (NR), for preventing boarding ladder that ship-dragging the connects safety zone of drifting, disengaging ship in the time of just should making ladder drift to limit position.
On-board and off-board have the quite a while because boats and ships docks afterwards with ladder, for energy-conservation and avoid the waste gas and the noise effect passenger of motor, the scheme that employing kills engine.Simultaneously, adopt above-mentioned accumulation of energy emergency device to stock the hydraulic pressure energy in advance again, cause drifting of ladder to transfinite when drifting of boats and ships transfinites, in the time of must breaking away from boats and ships, above-mentioned accumulation of energy emergency device just can provide the hydraulic pressure energy, by hydraulic control device, finishes disengaging work.
Realized energy-conservationly, safety and passenger are not subjected to the purpose of the influence of engine exhaust and noise.
