Description
Technical field
The present invention relates to a kind of from boat steel rake grab boat hydraulic system.
Background technology
There is certain defect, inefficiency at the aspect such as service behaviour, version in the existing steel rake grab boat hydraulic system of boat certainly, needs to be improved further.
Summary of the invention
It is an object of the invention to provide the steel rake grab boat hydraulic system of boat certainly using safety of a kind of favorable working performance.
The technical solution of the present invention is:
A kind of from boat steel rake grab boat hydraulic system, including hydraulic actuating mechanism, hydraulic power unit, hydraulic control system, fluid pressure line, hydraulic electric control system, it is characterized in that:
(1) hydraulic actuating mechanism includes spud gantry lifting device four set, chassis walking oil cylinder two, steel rake hauling winch one, four, windlass capstan winch；
(2) system dynamic pump assemble put as follows:
Often set lowering or hoisting gear joins the electric-motor pump group parallel connection fuel feeding of 2 22KW to hoist cylinder, and when separate unit runs, the speed of service halves, and meets an urgent need each other for i.e. two, improves the reliability of system, full ship totally 8 electric-motor pump groups；
Full ship adjusts two 4KW electric-motor pump groups to be plugging pin oil cylinder fuel feeding, opens one for one or two and with meeting an urgent need each other depending on actual condition, and because the feature of plugging pin oil cylinder is that the operation time is short, moment flow greatly, therefore sets the accumulator of 2 volume 40L in pump discharge oil circuit;
The lifting pumping source of 1# lowering or hoisting gear is held concurrently for 1# chassis oil cylinder, the lifting pump of 2# lowering or hoisting gear is held concurrently for 2# chassis oil cylinder, the lifting pumping source of 3# lowering or hoisting gear is held concurrently for hauling winch, and the lifting pumping source of 4# lowering or hoisting gear is held concurrently for 4 windlass capstan winches, and plugging pin oil cylinder pumping source provides power oil sources for 8 main pump variablees simultaneously;

(3) hydraulic control system
Chassis oil cylinder, hauling winch, windlass capstan winch control mode relatively simple, wherein four windlass capstan winches use the other hand-operated valves of machines to control, and chassis oil cylinder and hauling winch use electro-hydraulic control；
The control of lowering or hoisting gear:
Having hoist cylinder four in every covering device, and four oil need synchronization lifting, from the structure of lowering or hoisting gear, four hoist cylinders are actually mechanism and synchronize, and therefore four oil cylinders in parallel can use 1 way reversing valve to control to commutate；Due to guide pile decline and hull decline for oil cylinder be two different oil pockets by back-pressure balance control, therefore, being both needed in the total oil circuit of A, B of reversal valve, one-way balance valve is set and make back pressure control and hydraulic locking；
Owing to the mounting means of hoist cylinder is two oscillating bearing, the swing of certain amplitude is there is when oil cylinder runs, therefore the AB hydraulic fluid port of every oil cylinder is connected with house steward AB and need to use high-pressure hose transition, safety in view of system, therefore every oil cylinder is both needed to arrange hydraulic lock, there is the back pressure of one-way balance valve in the oil return of this hydraulic lock, so this hydraulic lock need to use the product that external control leaks；
In the flexible pipe anti-explosion safety item of hoist cylinder AB hydraulic fluid port, also have another kind of scheme available, it is simply that A mouth and B mouth at four hoist cylinders are all provided with fixing damping hole, cancel the hydraulic lock on single oil cylinder；Such four oil cylinders are in all the time under parallel connection and work, even if explosion occurs in a certain flexible pipe, hull at most simply declines a stroke the most lentamente；
Upper and lower two groups of totally four plugging pin oil cylinder are had in lowering or hoisting gear, often two simultaneous retractables in parallel of group, for guaranteeing the safety of system, two group oil cylinders use " P " type reversal valve to control, so two groups of latches of initial condition are all in extended position, only having one group of latch to extract during commutation, under the most any operating mode, the most at least one group of latch is in the state of stretching out, it is ensured that the safety of system；
(4) fluid pressure line and hydraulic oil
Full ship fluid pressure line is made by hydraulic system principle figure requirement by shipyard, for improving the net synchronization capability of four oil cylinders, house steward AB needs with the arm of four oil cylinders to use " centrosymmetry " stringing to be connected, the hydraulic fluid port making every oil cylinder is identical to the oil channel structures of house steward, so can improve the synchronization of oil cylinder the most further；Using No. 68 antiwear hydraulic oils, oil cleanliness is NAS8 ~ 9 grade；
(5) hydraulic electric control system
Full ship hydraulic electric control system is made up of other control chamber four part of Electric Machine at Pumping Station control chamber, PLC centralized-control box, driver's cabin centralized control panel and stake, and each several part sets following functions:
The automatically controlled control chamber of pumping plant: the star triangle on off control of 8 22KW, and 2 4KW motors directly initiate control, and set the Remote Control Interface of driver's cabin, degree of protection IP22, be arranged in pumping plant cabin；
PLC control cabinet: PLC control cabinet realizes system-wide accurate control, and alarm signal controls and interlocking, and panel sets on and off switch, and degree of protection is IP22, may be arranged at pumping plant cabin or drives indoor；
Driver's cabin centralized control panel includes:
Control on and off switch；The remote control of motor is opened and runs instruction；Hydraulic system concentrates sound and light alarm；The operation oil pressure of each pumping source shows；Level indicator；2 set chassis oil cylinders control and run instruction；1 set hauling winch controls and runs instruction；Two kinds of operating modes of main oil pump select switch；Hoist cylinder extension and contraction control, stroke show, extreme position indicates, four set lifting synchronizations of jacking up；Plugging pin oil cylinder pull pin control and snibbing position show；" audition ", " noise reduction " switch；Running status and alarm indicator use HMI to show；
