Abstract
The invention discloses a marine jib crane luffing structure. Three booms are arranged at the front end of a platform through rotating shafts, three tripods are arranged at the rear end of the platform, a winding drum which is powered by a motor is arranged at the top end of each tripod, a steel rope on the winding drum is fixedly connected with the top end of each boom, three bottom sliding mechanisms are arranged in the middle of the platform, and are connected with telescopic oil cylinders through rotating shafts, and the top end of each telescopic oil cylinder is connected with the middle of each boom correspondingly one by one. According to the marine jib crane luffing structure disclosed by the invention, a steel rope luffing mechanism and a telescopic cylinder luffing mechanism are matched with each other for use, so that relatively light objects can be lifted by directly using the steel rope luffing mechanism when a crane lifts the relatively light objects, and when the lifted objects are overweight, firstly the telescopic cylinder luffing mechanism can be used for luffing lifting, and then the steel rope luffing mechanism is appropriately adjusted to be matched with the telescopic cylinder luffing mechanism, so as to avoid the excessive wear of a steel rope.
Description
Technical field
The present invention relates to a kind of arm derrick crane luffing structure peculiar to vessel.
Background technology
Luffing is a most important functions of arm derrick crane, so-called luffing, just refers to that crane arm support is changing lifting goods radius perpendicular to carrying out angle change in plane.At present, nearly following three classes of the luffing of deck crane:
1. utilize electrical motor by reductor or hydraulic actuator band movable reel, steel rope pull crane arm support front end to carry out luffing, this hoisting crane is again electronic or hydraulic pressure cable lift; Cable wire arm derrick crane cost is high, needs a large amount of steel ropes, the easy abrasion of steel rope, complex structure, easily uncertain fault occurs, maintenance difficult, Heavy Weight, bulky, expensive.
2. utilize hydraulic ram telescopic band swing arm frame to carry out the hydraulic arm gantry crane of luffing, hydraulic lift cost is high, and efficiency is low, complex structure, easily uncertain fault occurs, and volume is large, and price is more expensive.
3. another crane arm support is cantilever, can not luffing, but on jib, hang an electric block, on jib, lifting goods radius is changed as longitudinal travel by electric block, this hoisting crane is again electronic cantilever derrick, and electronic cantilever derrick volume is comparatively large, Heavy Weight, price are higher.
Therefore existing hoisting crane all can not meet the use needs of existing people work, and how designing a kind of durable, economic variable amplitude mechanism for crane becomes people's problem anxious to be resolved.
Summary of the invention
The present invention is directed to the proposition of above problem, and a kind of arm derrick crane luffing structure peculiar to vessel of research and design, in order to solve existing variable amplitude mechanism for crane, cable wire arm derrick crane steel cable serious wear, Hydraulic for lifting load engine efficiency is low, electronic cantilever derrick costly, can not meet the shortcoming of the use needs of people.The technological means that the present invention adopts is as follows:
A kind of arm derrick crane luffing structure peculiar to vessel, comprises steel cable luffing mechanism and telescoping cylinder luffing mechanism; Described steel cable luffing mechanism comprises: spider, reel and steel cable; Described telescoping cylinder luffing mechanism comprises: basal sliding mechanism, turning cylinder and telescopic oil cylinder; The front end of platform is provided with three jibs by turning cylinder, rear end is provided with three spiders, the top of each described spider is provided with the reel being provided power by motor, steel cable on reel and the top of jib are connected and fixed, the middle part of described platform is provided with three basal sliding mechanisms, described basal sliding mechanism is connected with telescopic oil cylinder by turning cylinder, and the top of each described telescopic oil cylinder connects one to one with the middle part of each jib respectively.
Be multi-stage expansion oil cylinder as preferred described telescopic oil cylinder.
Bottom as preferred three described jibs is provided with suspender mechanism, and described suspender mechanism is fixedly connected with jib top by steel cable.
Compared with the prior art, arm derrick crane luffing structure peculiar to vessel of the present invention, use steel cable luffing mechanism and telescoping cylinder luffing mechanism two kinds of luffing mechanisms simultaneously, steel cable luffing mechanism and telescoping cylinder luffing mechanism with the use of, hoisting crane can be allowed when hanging the object of lighter in weight, direct use steel cable luffing mechanism lifts by crane, when the object of lifting is overweight, first can carry out luffing lifting by telescoping cylinder luffing mechanism, then coordinate at suitable adjustment steel cable luffing mechanism, avoid the undue wear of steel cable, and be provided with basal sliding mechanism bottom telescoping cylinder luffing mechanism, make people can according to the distance angle of telescoping cylinder luffing mechanism and jib, adjust a suitable position, again telescopic oil cylinder is acted on, jib is regulated, this luffing mechanism control process can be made more laborsaving.
