Abstract
The invention relates to an anti-collision device for a dock. The anti-collision device for the dock comprises a plurality of double-acting single-piston type oil cylinders (2) mounted in a dock docking shore (1), a piston rod (3) of each double-acting single-piston type oil cylinder (2) is capable of extending out of the front side wall of the docking shore (1), an anti-collision cushion (4) is fixed at the outer end of each piston rod (3), and each double-acting single-piston type oil cylinder (2) is controlled by a hydraulic system to control the stretch of each piston rod (3). When a ship is close to the shore, the oil cylinders work ahead of time, the piston rods extend outwardly so as to enable the anti-collision cushions at the outer ends of the piston rods contact with the ship body, resistance is improved properly, and the ship speed is reduced gradually so as to safely arrive on the shore; and in addition, each oil cylinder is controlled by the hydraulic system to control the stretch of each piston rod, so that the automatic control is realized conveniently.
Description
Technical field
The present invention relates to crashproof cushion technique field, relate in particular to a kind of collision proof device for wharf.
Background technology
The place of stopping at shipping harbour, fishing port, boats and ships, impaired in order to prevent that ship and harbour from bumping against, conventionally the tire of fixedly scrapping on harbour stop bank sidewall or other rubber object are as anticollision device, collision-prevention device, and this anticollision device, collision-prevention device has certain safety protection function to hull, and cost is low.But utilize junked tire also to have a lot of defects; 1, in the time that boats and ships pull in to shore; because hull is also in motion; and junked tire is fixed; hull only has while approaching bank soon; junked tire just plays a protective role; hull is very large to the impact force of tire; between junked tire and hull, also can produce larger friction; still can cause damage to hull surface; protective effect fixing and that the boats and ships of quick landing pier are played is limited, and when ship is stopped excessive velocities, manpower cannot be protected its hull.2, comparatively difficulty of the maintenance work of the anticorrosion anti-salt of rubber fender.3, junked tire outward appearance is ugly, affects waters view around.
If an application number is the Chinese invention patent " a kind of dock crash-proof cushion " of ZL200710157055.3 (notification number is CN101168960A), the patent No. is the Chinese utility model patent " a kind of dock crash-proof cushion " of ZL200720191425.0 (notification number is CN201172811Y), and the patent No. is that the Chinese utility model patent " Collsion proof dampener of wharf " of ZL200620021006.8 (notification number is CN2911005Y) has disclosed various relatively improved collision proof device for wharfs.
But they are the device that is fixed on bank, be all passive crashproof, and can only when hull almost pulls in to shore, just work, the impact force that hull and device are subject to is all very large.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of collision proof device for wharf that reduces ship's speed and hull is pulled in to shore rallentando that can move for above-mentioned prior art present situation before hull pulls in to shore prerequisite soon, it can better guarantee that hull pulls in to shore safely, installs in addition as realizing automation control possibility is provided.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of collision proof device for wharf, it is characterized in that: comprise that being arranged on harbour stops multiple double acting list ram cylinder in bank, the piston rod of each double acting list ram cylinder can stretch out the front side wall of stopping bank outward, the outer end of piston rod is fixed with bumper, and described each double acting list ram cylinder is stretching with control piston bar by HYDRAULIC CONTROL SYSTEM.
Above-mentioned hydraulic system comprises 3-position 4-way solenoid operated directional valve and controls the computer processor of 3-position 4-way electromagnetic switch valve events, the oil-in of this 3-position 4-way solenoid operated directional valve is communicated with oil pump, oil return opening is communicated with oil sump tank, the first hydraulic fluid port is communicated with the rod chamber of single ram cylinder, and the second hydraulic fluid port is communicated with the rodless cavity of single ram cylinder.It is few that this hydraulic system relates to parts, simple in structure, passes through in addition the oil-feed of the switching controls oil cylinder of 3-position 4-way solenoid operated directional valve gear
Above-mentioned oil pump is communicated with the oil-in of 3-position 4-way solenoid operated directional valve by choke valve.Choke valve is set and can allows piston rod slowly flexible, when hull touches after the bumper of piston rod outer end, piston rod slowly inside contracts, and makes hull slowly near stopping bank, further guarantees to stop safety.
Above-mentioned choke valve is variable throttle valve.
Above-mentioned bumper is rubber anti-collision pad or silica gel bumper.This bumper material can better be protected hull surface.
The dismountable outer end that is connected to piston rod of above-mentioned bumper.Be convenient to like this change bumper.
Also comprise multiple in order to detect hull offshore distance and the laser displacement sensor of the speed of pulling in to shore, described computer processor has signal input part and signal output part, the signal output part of this laser displacement sensor is connected with the signal input part of computer processor, and the signal output part of computer processor is connected with the control end of 3-position 4-way solenoid operated directional valve.
It is a kind of this anticollision device, collision-prevention device concrete mode of control automatically that realizes, laser displacement sensor imports the signals such as hull distance, speed into computer processor, by the working position of computer processor control 3-position 4-way solenoid operated directional valve, the piston rod that 3-position 4-way solenoid operated directional valve is realized the single ram cylinder of control according to different operating position is flexible again.
Compared with prior art, the invention has the advantages that: in the time that hull soon pulls in to shore, oil cylinder is worked in advance, piston rod is overhanging, allows the bumper of piston rod outer end contact with hull, and improves suitable resistance, reduce gradually the speed of boats and ships, pull in to shore with the safety that realizes boats and ships; In addition oil cylinder by HYDRAULIC CONTROL SYSTEM flexible with control piston bar, be convenient to realize automation control.
