Description
Technical field
The utility model relates to a kind of super large heavy-duty hoisting equipments, belong to technical field of crane equipment.
Background technique
With the fast development of international energy and petrochemical industry project construction field, modularization, enlargement and integration in engineering
Lifting requirements are continuously improved, and to crane facility lifting capacity and hoisting moment, more stringent requirements are proposed.But super large shape rises and resets
Standby use is often several typical large-scale operating conditions, and frequency of use is not high in real work；And super-big and overweight part lifts
When ground grounding pressure (grounding pressure: refer to and the vertical load born on the unit area of ground contact object) larger, ground
Base processing cost is higher.Therefore, cost is reasonable, dismounts convenience, and element usage is high, and grounding pressure is small, while can satisfy again
The lifting equipment of certain super large duty requirements requires higher and higher.
Super large heavy-duty hoisting equipment is a kind of crane of new model, with the big advantage of lifting capacity and hoisting moment, often
It is used as the lifting of super-big and overweight part.With the fast development of international energy and chemical field, the construction of super-big and overweight part part is more next
It is more.Under the premise of considering that cost and dismounting are convenient, increase substantially the elevating capacity of lifting equipment, reduce grounding pressure and
Collecting the higher lifting equipment of utilization rate is trend of the times.Traditional ring rail crane structure is illustrated as shown in Figure 1, Full Rotary
The counterweight of ring rail crane is fixed on platform, and the variation of complete machine hoisting moment is by adjusting ring rail diameter with reality
Existing, entire conversion process is extremely complex, the counterweight of half rotary ring rail crane is placed on the ground, and complete machine front chassis is around counterweight
Center steering, balance position can not move.The variation of such mode ring rail crane hoisting moment be by adjusting front chassis with
What the distance between counterweight was realized, entire conversion process is extremely complex.
The prior art one, ring rail crane shown in FIG. 1, circular orbit are inside and outside double rail type, and counterweight is fixed on platform,
It is irremovable, generally realized by increasing platform balance weight, reinforcing complete machine structure or adjustment adjustment race way diameter size.
Complete machine does not have deformation function, and the adjusting of elevating capacity is only capable of through reinforced structure part ability, increases counterweight quantity or adjustment
The adjusting of race way diameter, elevating capacity is limited, and is limited by the limitation of traffic condition, and structural member is also impossible to unconfined add
By force.
The prior art two: the super large heavy-duty hoisting equipment of counterweight variable width shown in Fig. 2, be by the technology of ring rail crane with
The super-starting balance weight technology of crawler crane combines, and improves rising for complete machine by changing counterweight quantity and the amplitude of suspended counterweight
Gravitational moment.Removing suspended counterweight can be changed to traditional ring rail crane shown in FIG. 1.The adjusting of elevating capacity is except through scheme
One form can also be adjusted, but the adjusting of performance is subject to outside being adjusted by way of increasing suspended counterweight
The limitation of complete vehicle structure part bearing capacity.If bearing capacity when complete vehicle structure part is according to suspended counterweight matches, when whole
When vehicle works without suspended counterweight, structural member bearing capacity surplus capacity is larger, and holding for vehicle can be reduced when especially cantilever crane is heavier
Loading capability；If bearing capacity when complete vehicle structure part is according to without with suspended counterweight matches, when vehicle band suspended counterweight work
When making, structural member bearing capacity is insufficient, and the bearing capacity of vehicle gets a promotion limited.And complete machine will guarantee to hang during the work time
Extension counterweight is liftoff, and otherwise lifting equipment not can be carried out revolution operation.This requires during design and use, lifting appliance and
The weight and its work range of its work range and suspended counterweight exact matching, to keep the whole machine balancing of system.And work as
When heavy-duty machine working condition changes, such as lifting weight amplitude is changed, it is necessary to be adjusted the quantity of suspended counterweight at any time, be carried out
The increase or reduction of counterweight quantity, thus guarantee that suspended counterweight is liftoff, large labor intensity, low efficiency.And when not hanging load, it hangs
Hanging counterweight all can be on whole pressure ground, and lifting equipment can not be turned round at this time, needs all to remove suspended counterweight at this time,
Host is turned back to suitable position, and whole suspended counterweights is then moved to corresponding position again using auxiliary hoist, from
It is newly assembled, inefficiency, greatly reduces the practical performance of crane.When lifting appliance is increasing, suspended counterweight
Weight and amplitude can all increase therewith, realize the liftoff of suspended counterweight, will greatly increase the negative of mast, mast and host
Lotus, the stability to vehicle are also serious prepare for the postgraduate qualifying examination.The ground flat degree and ground loading ability of suspended counterweight are parked simultaneously
Also it to meet the requirements.
Therefore, scheme one and two whole bearing capability of scheme are promoted limited, cannot carry out phase according to actual lifting demand
The adjusting answered, the trolley being less able to achieve in the utility model become the function of two trolleys；Vehicle grounding pressure is larger, over the ground
The requirement for bearing capacity of base is higher；Vehicle utilization rate is not high.

It is smaller；When lift it is relatively light when, can split into two independent equipment carry out using.The transformation of big trolley is only needed track
It is simply adjusted, the structural members such as principal arm, mast is split, mapping mode is simple, and element usage is high.
Principal arm operating condition is only embodied in the technical program, it is equally applicable for auxiliary operating condition etc..This programme middle mast and flat
Using suspension pulling plate connection between platform, can also be attached using mast, mast can also decompose and be assembled into two
Set is independent to be used；Cantilever crane in this programme is A arm frame, not limited to this, is also possible to parallel both arms frame etc.；In this programme
Schematic diagram only indicates principle, it is not limited to this, three trolleys, four trolleys etc. can also be split into simultaneously.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
It also should be regarded as the protection scope of the utility model into deformation.
