Description
Technical field
The present invention relates to a kind of ship loop wheel machines.
Background technology
Ship loop wheel machine is the machinery that cargo ship is served only for cargo lifting, handling, it is the important component of ship, because
Limited space on ship, various to be arranged closely using equipment and Ship Structure, the direct shadow of stability of ship loop wheel machine work
Ring the safety to carrying cargo.The considerations of for safety factor, each ship are limited by installation position and attached in ship loop wheel machine
In the case of nearly fixation or on-fixed obstacle, it is necessary to increase enforceable automatic spacing function, function, which is divided into, to be entirely limited and area
Domain limits two kinds.It is exactly loop wheel machine under any operating condition to be entirely limited, and does not allow access into the limitation of the rotary area;Region
It is limited to only when the loop wheel machine arm support elevation angle is higher than a certain angle, can just rotate into the limitation in region, and after entering the region, arm
The frame elevation angle cannot be below condition height.Existing limit realization method is according to hull layout drawing, and advance correspondence is having obstacle
Spacing zone welded limiting baffle, and hydraulic pressure or electric limiting switch induction region boundary are selected, realize that limit stops function.
Spot ship loop wheel machine is divided into folding-jib loop wheel machine and straight arm type loop wheel machine by structure type.The arm of folding-jib loop wheel machine without using
When be in folded state, be in extended configuration when use, it is flexible convenient to have the characteristics that, but load capacity is poor;Straight arm type loop wheel machine
Arm always is longitudinally disposed, has the characteristics that overload capacity is strong, but underaction is convenient.Folding-jib loop wheel machine and straight arm type are hung
The function of machine is all relatively simple, and the handling situations of each self application are limited.Especially ship loop wheel machine is required to need to revolve in handling goods
Turn and span it is larger when, not only unable to do what one wishes, ship is influenced by the huge lateral torque of suspension bridge and generates apparent shaking.
In order to improve the Stability and dependability of ship loop wheel machine delivery, there is higher requirement to ship loop wheel machine.
Invention content
For the above situation, the present invention provides a kind of telescopic single armed tower crane of freighter, and usually it is shelved on arm shelf,
When work, it is not limited with region by being entirely limited, and can be increased and the self-balancing type boom assembly rotated and movement therein
Formula hoisting mechanism, can direct small, large span handling goods, dependence of the elimination to wharf crane between ship and harbour.
The invention is realized in this way:The telescopic single armed tower crane of freighter is characterized in:Telescopic single armed self-balancing tower crane is hung
Arm shelf is located on freighter, and usually the self-balancing type boom assembly in telescopic single armed self-balancing tower crane is shelved on arm shelf
On;
The telescopic single armed self-balancing tower crane, telescopic base assembly are mounted on freighter, the rotation in telescopic base assembly
Turn to dispose self-balancing type boom assembly on assembly;
The top surrounding of the telescopic base assembly, support arm sets top sheave device, and the lower part surrounding of inner support sets cunning
Wheel apparatus, inner support are nested in support arm;Inner support is driven to make elevating movement by lift assembly, in this way, telescopic pedestal is total
Achievement can be lifted quick smoothly.
Self-balancing type boom assembly includes the hammerhead carriage amplitude varying horizontal arm support that crane arm is connected with counter-jib, is risen
It sets mobile hoisting mechanism in weighing arm, in mobile hoisting mechanism or sets lifting, mobile instrument.
It is set in telescopic base assembly including height limiting device, amplitude limiter, slewing limiter.
It is set in self-balancing type boom assembly including load lifting limiter, shackle bolt lock device, Anti-breaking rope device.
The present invention effect be:
(1) its telescopic base assembly of is placed on the deck of freighter, usually certainly flat in telescopic single armed self-balancing tower crane
Weighing apparatus formula boom assembly is shelved on arm shelf, is not take up bin location.
It at work, using telescopic base assembly can with quick and stable lift and rotation assembly can with 360 ° revolve
The function of turning, self-balancing type boom assembly and mobile hoisting mechanism therein are not limited with region by being entirely limited, can be in ship
Direct small, large span handling goods between oceangoing ship and harbour eliminates the dependence to wharf crane, solves conventional tower crane descending operation
Complicated, quite time-consuming problem.
(3) its self-balancing type boom assemblys of eliminate ship by the rolling that the huge lateral torque of suspension bridge is influenced and is generated
It is dynamic.
(4) a series of its protective devices of enable it to limited space aboard ship, various to use equipment and Ship Structure cloth
It sets in freighter closely and applies.
(5) in mobile hoisting mechanisms or set lifting, mobile instrument, this addresses the problem length of steel rope distance be laid with easily by
Windage and the problem of rock unstability.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the schematic diagram of the telescopic single armed tower crane of freighter of the present invention.
Fig. 2 is the telescopic base assembly schematic diagram in the telescopic single armed tower crane of freighter of the present invention.
In figure:1. telescopic base assembly, 2. self-balancing type boom assemblys, 3. arm shelves, 4. freighters are sliding on 5.
