Description
Technical field
The invention discloses a kind of universal moment mechanism for deck crane telescopic type anti roll device, belong to deck crane machinery anti-swinging technology field.
Background technology
When ship hoisting crane carries out relevant operation at sea, because the steel rope hanging weight belongs to flexible piece, when hoisting crane carries out the action such as luffing, revolution, weight can produce and wave; In addition, due to wind, wave, flow, to gush etc. the impact of marine environment load, boats and ships can produce rolling, pitching, yawing, swaying, surging, heave six-freedom motion, and this just more exacerbates waving of weight, almost cannot carry out operation when sea situation is severe.Make the operation of deck crane under high sea situation very difficult like this, easily safety misadventure occurs.In addition, the plant machinery degree of deck crane is low, and a lot of back work is all complete by manpower, and not only labour intensity is large, also there is larger potential safety hazard.
Summary of the invention
In order to overcome the weak point in background technology, the present invention proposes a kind of universal moment mechanism for deck crane telescopic type anti roll device.
In order to achieve the above object, the technical solution used in the present invention is:
For a universal moment mechanism for deck crane telescopic type anti roll device, it is characterized in that: this universal moment mechanism comprises hanger, simplified, damper, ball pivot, connection reinforcement plate; Hanger is positioned on cylindrical shell, is fixedly connected on crane arm top end, and connector drum; Hydraulic ram one end is connected on arm, and the other end is connected on cylindrical shell; Three dampers are fixed on cylinder inboard wall, and the end of damper expansion link is connected with the upper connecting rod of ball pivot; The lower link end of ball pivot is connected with telescopic tube, and connection reinforcement plate is fixed on the junction of ball pivot lower link and telescopic tube.
This universal moment mechanism can with telescopic type anti roll device with the use of.Structure simultaneously due to universal moment mechanism is simple, is easy to be attached on crane arm, thus this universal moment mechanism also can with other mechanical anti roll device with the use of; Also can be used alone on marine crane boom as anti roll device.
A kind of universal moment mechanism for deck crane telescopic type anti roll device, principle of work is: during crane arm lifting amplitude-change, by the telescopic adjustment of hydraulic ram, head on cylindrical shell to rotate around fulcrum (hanger and hinged place, hoisting crane top), make cylindrical shell be in state straight down all the time.During lifting weight, due to the motion of ship that wave causes, the telescopic tube be connected with universal moment mechanism will bear certain wave load, and be delivered to the ball pivot be connected with telescopic tube, now, three the damper combineds action be connected with the upper connecting rod of ball pivot, counteract the moment that telescopic tube is transmitted by ball pivot, cushion its load, reduce the swing of telescopic tube.So, by universal moment mechanism, telescopic tube and the direct rigidly connected hanger part of arm can be prevented to be subject to excessive lateral wave wave load and to be pulled off, significantly can reduce the swing of telescopic tube simultaneously, play anti-effect of shaking.
The present invention is compared with background technology, and having useful effect is:
(1) shake universal moment mechanism by this deck crane telescopic is anti-, can reduce that hoisting crane carries out the action such as luffing, revolution and sea turn, wave, the impact of flowing, to gush etc. environmental load cause boats and ships to produce the waving of weight of rolling, pitching, yawing, swaying, surging, heave six-freedom motion and then generation.
(2) universal moment mechanism is connected to arm and mechanical anti-swing mechanism cleverly, prevents boats and ships mechanical anti-swing mechanism and boom portion in six-freedom motion situation to be pulled off because directly carrying out being rigidly connected.And the structure of this universal moment is simple, only need be attached on existing crane arm head, installs cost additional low.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figures 1 and 2, a kind of universal moment mechanism for deck crane telescopic type anti roll device, is characterized in that: this universal moment mechanism comprises hanger 3.3, cylindrical shell 3.4, damper 3.5, ball pivot 3.6, connection reinforcement plate 3.2 etc.Hanger 3.3 is positioned on cylindrical shell 3.4, is fixedly connected on crane arm 1 top end, and connector drum 3.4; Hydraulic ram 2 one end is connected on arm 1, and the other end is connected on cylindrical shell 3.4; Three dampers 3.6 are fixed on cylindrical shell 3.4 inwall, and the end of damper 3.6 expansion link is connected with the upper connecting rod 3.5 of ball pivot 3.7; Lower link 3.1 end of ball pivot 3.7 is connected with telescopic tube 4, and connection reinforcement plate 3.2 is fixed on the junction of ball pivot lower link 3.1 and telescopic tube 4.
A kind of universal moment mechanism for deck crane telescopic type anti roll device, principle of work is: during crane arm 1 lifting amplitude-change, by the telescopic adjustment of hydraulic ram 2, head on cylindrical shell 3.4 to rotate around fulcrum (hanger 3.3 with hinged place, hoisting crane top), make cylindrical shell 3.4 be in state straight down all the time.During lifting weight, due to the motion of ship that wave causes, the telescopic tube 4 be connected with universal moment mechanism will bear certain wave load, and be delivered to the ball pivot 3.7 be connected with telescopic tube, now, three dampers 3.6 combined action be connected with the upper connecting rod 3.5 of ball pivot 3.7, counteracts the moment that telescopic tube 4 is transmitted by ball pivot 3.7, cushion its load, reduce the swing of telescopic tube 4.So, by universal moment mechanism, telescopic tube 4 and direct rigidly connected hanger 3.3 part of arm 1 can be prevented to be subject to excessive lateral wave wave load and to be pulled off, significantly can reduce the swing of telescopic tube 4 simultaneously, play anti-effect of shaking.
