Description

The telescopic both arms tower crane of freighter
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 both arms 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 run-in index self-balancing type boom assembly that rotates and wherein Linkage mobile hoisting mechanism, can between ship and harbour direct small, large span handling goods, eliminate to wharf crane It relies on.
The invention is realized in this way:The telescopic both arms tower crane of freighter is characterized in:Telescopic both arms self-balancing tower crane is hung Arm shelf is located on freighter, and usually the run-in index self-balancing boom assembly in telescopic both arms self-balancing tower crane is shelved on arm and puts On frame;
The telescopic both arms self-balancing tower crane, telescopic base assembly are mounted on freighter, the rotation in telescopic base assembly Turn to dispose the double boom assemblys of run-in index self-balancing on assembly;It sets in the double boom assemblys of run-in index self-balancing and is limited including lifting capacity Device, shackle bolt lock device, hoisting mechanism linkage;
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.
The double boom assemblys of run-in index self-balancing include the tup that two crane arms disposed in parallel are connected with counter-jib Formula carriage amplitude varying horizontal arm support, all sets mobile hoisting mechanism in crane arm, in mobile hoisting mechanism or sets lifting, shifter Tool.
It is set in telescopic base assembly including height limiting device, amplitude limiter, slewing limiter.The effect of the present invention It is:
(1) its telescopic base assembly of is placed on the deck of freighter, usually parallel in telescopic both arms self-balancing tower crane The double boom assemblys of formula self-balancing are shelved on arm shelf, are 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 Directly small, large span loads and unloads large cargo between oceangoing ship and harbour, eliminates the dependence to wharf crane, solves conventional tower crane lifting Complicated for operation, quite time-consuming problem.
(3) its run-in index self-balancing type boom assemblys of eliminate ship and are influenced and generated by the huge lateral torque of suspension bridge Shaking.
(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 both arms tower crane of freighter of the present invention.
Fig. 2 is the telescopic base assembly schematic diagram in the telescopic both arms tower crane of freighter of the present invention.
Fig. 3 is the run-in index self-balancing type boom assembly schematic diagram in the telescopic both arms tower crane of freighter of the present invention.
In figure:1. telescopic base assembly, 2. run-in index self-balancing type boom assemblys, 3. arm shelves, 4. freighters, 5. top sheave device, 6. rotation assembly, 7. inner supports, 8. support arms, 9. lift assemblies, 10. lower pulley apparatus.
