Description
Technical field
The utility model relates to crane field, particularly a kind of can anti-storm wind mechanism design can be utilized to topple over the harbour jenny of transfer.
Background technology
Harbour movable crane is a kind of can, at the hoisting crane of harbour, stockyard transition operation, be the focused protection equipment at harbour, and these equipment, once suffer that destruction will have a strong impact on port security and produce, even cause a few paralysis in port.Both at home and abroad because of the large-scale port 13 weight-lifting equipment capsizing case that disaster caused by a windstorm causes, mainly contain two kinds of situations: one is the attack suffering vuthan in gale forecast situation, and the protection from the wind of harbour bank crane can not resist powerful wind-force.As Port of Zhanjiang prisoner in 1996 suffers 15 typhoons and cause 16 Finishing of Machinery in Large-Scale Port complete machine unstabilitys toppling, become and lose maximum harbour disaster after the founding of the state; Two is suffer the attack without the sharp-edged gust forecast.As in July, 1991 Qingdao Harbour burst hurricane, two bank crane cards collapse, and cause harbour container loading and unloading operation to stop production half a year; Two 1880t/h grab bucket ship unloaders that Baosteel Raw Material Wharf in 2004 is working are prominent meets hurricane and bumps against and collapse.China has many because the weight-lifting equipment that causes of burst wind damages the event causing harbour to be paralysed in recent years.Therefore be that harbour or hoisting crane originating firm are all paid much attention to wind protection.China is clear stipulaties in " safety rules for lifting appliances ", and the rail mounted of outdoor work works the machine of holding, and all should install wind-proof device, comprises windproof system fixing apparatus, anti-creep device and anchor fitting.The windproof safety device that novel fluid pressure type wind-proof iron wedge drg (abbreviation wind-proof iron wedge) and hydraulic wheel rim brake (being called for short clip wheel device) etc. are more advanced was installed in recent years in crane operating unit chassis group, good windproof AsA-GSH cycle had been served to the attack of the fitful wind and vuthan of resisting large wind.In view of this, due to the needs of unloading a ship, rubber tyre gantry crane design height is very high, and especially those hoisting capacities are larger, the hoisting crane that operating radius is larger, now, hoisting crane is when harbour, stockyard transfer, impassable because of limitation in height sometimes, and when overhaul, due to highly too high maintenance difficult, easily topple when storm wind, thus design a kind of jib and tower body can be fallen necessary in the design on ground.Chinese patent ZL201120353233.1 discloses a kind of single-cantilever-crane gantry crane, comprise door frame, rotating disk, machine house, equalizing bar, lower link bar, jib and driver's cab, also comprise column, rotating disk is provided with above door frame cylinder, column is provided with above rotating disk, the top of column is provided with equalizing bar, equalizing bar is connected with jib by the lower link bar of its bottom, column is provided with machine house, the column side being positioned at jib side is provided with driver's cab, hoist rope is walked around reel and is extended to below jib front end with some pulleys and be connected with suspension hook.It is high that this patent solves the whole door of single-cantilever-crane gantry crane in prior art machine center of gravity, thus affect the defect of the stability of complete machine, simultaneously hoist rope exist when moving simultaneously two kinds around to, provide one and greatly reduce machine gravity, the single-cantilever-crane gantry crane of prolonging service life of steel wire, though it reduces center of gravity, not substantial reduction complete machine height, still has the possibility of toppling over when meeting with storm wind, Chinese patent ZL201220297801.5 discloses a kind of energy-conservation stationary crane, it comprises base, base is provided with turntable, driver's cab and upper rotary column, crane arm installed by turntable, luffing assembly pulley is arranged on crane arm, luffing mechanism installed by turntable, lifting mechanism and rotating mechanism, upper rotary column is Detachable propeller strut, lifting mechanism is arranged as two covers, it comprises electrical motor, speed reduction gearing, coupler and reel, electrical motor is connected with speed reduction gearing by coupler, speed reduction gearing connects reel, speed reduction gearing installs drg relative to the opposite side connecting reel.Above-mentioned energy-conservation stationary crane is when ensureing less afterbody radius of turn, luffing mechanism, lifting mechanism and rotating mechanism are arranged on turntable, go up rotary column simultaneously and adopt Shears form, the deadweight of hoisting crane is obviously alleviated, energy saving and cost lowering successful.But this patent has been arranged to fixed type hoisting crane in order to the problem solved by storm wind blows down, though to some extent solve stormproof technical matters, because it can not move, can make troubles when keeping in repair, Chinese patent ZL201320373958.6 discloses a kind of Multipurpose port tire crane, it comprises lifting mechanism, turntable, combustion engine, luffing mechanism, swing type mechanism, Shears, jib, driver's cab, travel control housing, cable drum or cable box, hydraulic power unit and multiway valve, steeraxle, drive axle, traveling mechanism, movable supporting legs, fixed supporting leg and underframe, described lifting mechanism overlaps by two the winch that independently hoists and forms, both can drive separately, also can drive by synchronization combining, when utilizing twin rope grab as load-engaging device, handling and the stacking operation of pier storage yard and goods yard bulk goods can be realized, when utilizing suspension hook as load-engaging device, lifting and the loading and unloading operation requirement of pier storage yard and goods yard breakbulk can be realized, but it can not be put into when pre-storm wind exists potential safety hazard, Chinese patent publication No. CN 103723627 A discloses a kind of multifunctional crane, comprise some crane girders, straight rail, crane carriage and electric power system, the quantity of described some crane girders is greater than or equal to 2, parallel placement, the quantity of described straight rail is identical with the quantity of described some crane girders, be separately fixed at the end face of described some crane girders, the described straight rail of described crane carriage contact is placed on the top of described some crane girders, and described electric power system comprises power transmission system and electrical apparatus control system.By the way, the utility model multifunctional crane has novel structure, performance is stablized at a high speed, design dexterous uniqueness, interpersonal concordance, safe and reliable, work efficiency is high, easy to use, simple operation and other advantages, market outlook are widely had popularizing of multifunctional crane, but there is mobile inconvenience equally, can not the defects such as storm wind be put.Therefore, often there is complete machine excessive height and can not prostrately put in harbor crane of the prior art, the defect such as can not to move.
