Description
Technical field
The present invention relates to a kind of handling machinery, particularly a kind of light-duty transfer crane of half draw-crab type of loading and unloading container.
Background technology
In recent years, along with the expansion of China's Foreign Trade, the fast development of freight container traffic industry has driven the technological advance and the fast development of container handling device simultaneously.Portal crane is compared with the various hoisting cranes that other industry is used, and operating efficiency is high, and energy consumption is also generally very high, realizes that therefore the energy-conservation of container handling device is very great with the reduction of discharging meaning.Along with the lasting lifting of energy prices and going deep into of energy-saving and emission-reduction policy, the lightness of container handling device and economy will become a new development tendency.
Traditional tyred container door type crane and rail-mounted gantry container crane all are the important handling equipment of container hargour; Change dominate in the harbour container stockyard in modern times; The whole world has the tyred container door type crane of 7000 all sizes runing approximately at present; Account for 90% of storage yard container handling equipment, rail-mounted gantry container crane in the application in stockyard also more and more widely in recent years.They all have the characteristics that operating efficiency height, space availability ratio are high, capacity rating is high.But the traditional tyred container door type crane and the lifting mechanism of rail-mounted gantry container crane and wheeling mechanism all are arranged on the trolley frame; Make the weight big (up to 25 tons) of dolly; Thereby increased the weight of complete machine, there are shortcomings such as wheel load is big, cost is high, daily working service cost high, energy resource consumption is big in this kind equipment.
Reach along the line in inland river, interior the process that develops to the Changjiang river in freight container traffic, a large amount of medium and small container pier storage yards and transhipment station have appearred in various places.For medium and small pier storage yard,, will cause enterprise investment increase, economic benefit to descend if indiscriminately imitate coastal professional container depot technology pattern fully.Many medium and small container depots are in the face of traditional tyred container door type crane and rail-mounted gantry container crane; All exist the problem of " cannot afford, Guan Buqi, can not use ", and general weight-lifting equipment is difficult to accomplish the job requirement of container handling, pile, carrying.Therefore, press for the economical container handling device that a kind of ability is fit to particularly medium and small container pier storage yard in all kinds of harbours and transhipment station.
Summary of the invention
The present invention is exactly the light-duty transfer crane of a kind of half draw-crab type that under the above-mentioned background technology, proposes; It is great innovation to traditional gantry container crane version; Guaranteeing on the basis of original performance, a kind of simple in structure, lightness, economical and practical fixed type or rubber-tyred or rail mounted hoisting and handling equipment are being provided.
Technical scheme of the present invention is: the light-duty transfer crane of a kind of half draw-crab type; Comprise the lifting mechanism that is installed in the structure-steel framing front side; Be installed in trolley frame and wheeling mechanism on the structure-steel framing girder track; The suspender that is connected with trolley frame through the first, second, third and the 4th steel rope, and the suspender revolution reclining device that is installed in the structure-steel framing rear side; First end of described first to fourth steel rope is connected on the reel of said lifting mechanism; Second end of described first to fourth steel rope is walked around the assembly pulley of structure-steel framing, dolly, suspender respectively, and is connected to the steel rope fixed end that suspender turns round the two ends of reclining device or directly is fixed on the structure-steel framing rear side respectively.
Described lifting mechanism is 1 cover, is installed on the structure-steel framing lower platform of front side, and the reel of said lifting mechanism is the tetrad reel, links to each other with first end of the 4th steel rope with first, second, third respectively.The reel of said lifting mechanism also can be double crosslinking drum, and totally 2 overlap, and first double crosslinking drum links to each other with first end of first and second steel ropes respectively, and second double crosslinking drum links to each other with first end of third and fourth steel rope respectively.The reel of said lifting mechanism is driven by motor and retarder, and described motor is an alternating-current variable frequency motor.Wheeling mechanism only is set on the described trolley frame, lifting mechanism is not set.
Compared with prior art; The invention has the beneficial effects as follows: 1), lifting mechanism is arranged in the structure-steel framing lower platform, has reduced the weight of dolly through special structural design; Make the top weight of hoisting crane move down; Increased complete machine stability, realized the equipment lightness, made complete machine have from characteristics such as heavy and light, reduced investment, energy consumption be low; 2) wheel forces down, and has not only reduced the stockyard infrastructure investment, and has reduced wear of wheel, saves and safeguards and use cost.
