Detailed description of the invention
The invention discloses a kind of Deep-foundation grab crane, be to fetch earth for grabbing soil during Construction of Deep Foundation
The professional equipment of design, is not limited by construction depth, is had the advantages that unearthed efficiency is high.
In order to make it easy to understand, existing technical term the present invention program related to is explained as follows:
Deep foundation: deep foundation is that buried depth is relatively big, using bottom firm stratum or rock stratum as the basis of supporting course,
Its effect is the deep layer load born relatively centrally being delivered to ground, and unlike shallow foundation,
Be by the bottom of foundation the load diffusion profile born in the shallow-layer of ground.Therefore, building yard is worked as
Shallow-layer soil property can not meet the building requirement to ground bearing capacity, and don't suitably use ground
It is necessary to be considered as deep foundation scheme during base treatment measures, 20 meters the most deeper.
Grab bucket: with the bucket capturing silt and various bulk goods can open and close.Hydraulic pressure can be divided into by type of drive
Formula grab bucket and mechanical type grab bucket two big classes.Fluid pressure type grab bucket itself, equipped with opening-closing structure, typically uses hydraulic oil
Cylinder drives；Mechanical type grab bucket itself is configured without opening-closing structure, is generally driven by rope or connecting rod external force.
Hydraulic crawler crane: be the mobile crane of a kind of high-building construction.It it is a kind of profit
With track-type swing arm revolving crane.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the present invention, and
It is not all, of embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing
Go out the every other embodiment obtained under creative work premise, broadly fall into the scope of protection of the invention.
Refer to the structural representation of the Deep-foundation grab crane that Fig. 1, Fig. 1 provide for the embodiment of the present invention.
The Deep-foundation grab crane that the embodiment of the present invention provides, its core improvement is, including crawler belt
Running gear 1, stage apparatus 2, winding plant, jib group 5 and grab mechanisms 7, this winding plant bag
Include the master winch device for promoting grab mechanisms 7, and for providing the secondary winding plant closing bucket pulling force,
The secondary hoisting rope 3 of major-minor rolling control and master winch steel wire rope 4 are as shown in Figure 1.
From above-mentioned technical scheme it can be seen that the embodiment of the present invention provide Deep-foundation grab crane,
Car load integrates crawler crane and grabs bucket, and has the design of installing additional of crawler crane, ground connection ratio
Pressing little, stability is strong, and the fast lifting for a large amount of soil provides solid architecture basics, advanced practical；
Grab mechanisms is promoted by elevator structure, compared with the grab bucket of existing mechanical type, it is possible to reach deeper to capture
The degree of depth (40～50 meters are deep), elevator structure can provide superpower hoisting power and Grasping skill simultaneously, from
And accelerate to promote speed (50～60m/min can be reached), strengthen soil ability of grabbing, grab soil reaching raising
The purpose of soil extracting efficiency.It is big that this programme complete machine has dipper capacity, easy to operate, multi-functional, low cost
Feature.
As preferably, master winch device and secondary winding plant are controlled by variable dual-pump general power in parallel.Total work
Rate controls, it is simply that needing smaller power at a pump, the most remaining power can be used for another pump, in pole
In the case of end, each pump can provide peak power, and in most cases, major-minor elevator is all for this car
Needing different power, it is possible to achieve energy-efficient, power utilization maximizes.
Further, master winch device and secondary winding plant are respectively used to control main winch motor and secondary elevator
Motor, it is possible to realize double hoisting by design of Hydraulic System and synchronize.Double hoisting synchronizes, currently available technology
Being realized by electronic control technology, cost is high, and the design uses simple design of Hydraulic System, it is achieved double
Elevator synchronizes.
The Deep-foundation grab crane that the embodiment of the present invention provides, its secondary winding plant uses 4 multiplying power pulleys
Group design.Major-minor elevator list rope tension can reach 10T, has superpower hoisting power, closes bucket employing 4
Multiplying power assembly pulley designs, and closes bucket power and can reach 40T, has superpower Grasping skill.
In this programme preferred embodiment, the grab mechanisms 7 stable dress by slide block type pulley block structure
Put 6 and be connected to jib group 5.In the prior art, stability devices is trolley type, it is simply that leading of dolly
Rail is placed on above jib or the rigid guideway on ground, length limited system, poor stability；And the present invention
Then the steel wire rope having made flexibility into creative for rigidity with movable slider, and multiplying power can be increased at any time,
Increase rope capacity, after reaching four or five ten meters of degree of depth, still can arrive good stabilization,
Its structure chart is as shown in Figure 1.The grab bucket using slide block type pulley block structure that the present invention implements to provide is stablized
Device is advanced, and simple and practical, stability is superior.
In order to optimize above-mentioned technical scheme further, the deep foundation grab bucket lifting that the embodiment of the present invention provides
Machine, its complete machine uses crawler-type telescopic chassis, improves job stabilization.
In sum, the Deep-foundation grab crane in this programme, car load uses tracked hydraulic crane
Installing design additional, grounding pressure is little, and stability is strong；Major-minor elevator is controlled by variable dual-pump general power in parallel,
Controlling major-minor hoist motor respectively, it is achieved double hoisting synchronizes, master winch promotes grab bucket, and secondary elevator provides and closes
Bucket pulling force, major-minor elevator list rope tension can reach 10T, has superpower hoisting power, closes bucket employing 4
Multiplying power assembly pulley designs, and closes bucket power and can reach 40T, has superpower Grasping skill；Grab bucket uses slide block
Formula assembly pulley stabilising arrangement, simple and practical, stability is superior.
The Deep-foundation grab crane that the embodiment of the present invention provides, has the advantage that
1, speed is promoted fast, 50～60m/min；
2, capturing the degree of depth deep, 40～50 meters deep；
3, grab bucket stabilising arrangement is advanced, and stablizing effect is good；
4, complete machine is hydraulically operated, and has the advantages that impact Grasping skill is strong；
5, complete machine uses crawler-type telescopic chassis, good stability；
6, the grab bucket of complete machine collection and hydraulic crawler crane and one, advanced practical；
7, complete machine has dipper capacity greatly, easy to operate, multi-functional, low cost feature.
In this specification, each embodiment uses the mode gone forward one by one to describe, and each embodiment stresses
Being the difference with other embodiments, between each embodiment, identical similar portion sees mutually.
