Technical field
The utility model relates to construction machinery and equipment, crane facility field, particularly a kind of counterweight self-disassembly and assembly device and the hoisting crane of this counterweight self-disassembly and assembly device is housed.
Background technology
Movable crane need be used counterweight and come balance lifting weight to keep stable in use.Along with the increase of movable crane tonnage, corresponding counterweight weight also increases thereupon.Owing to the qualification of complete vehicle weight, for the ease of using, counterweight has to make removable moving counterweight, and promptly counterweight is only installed when hoisting crane hangs the work of carrying on demand.Therefore, realize counterweight from dismounting, promptly do not need other hoisting crane or lifting device to assist, hoisting crane self just can be accomplished the counterweight dismounting important that seems.Simultaneously, along with the increase of counterweight weight, also increasingly high to the security requirement of counterweight self-disassembly and assembly device.
In the prior art, most of counterweight self-disassembly and assembly device mainly draws high counterweight to the installation site through the oil cylinder that is installed on the turntable.During work, rely on oil cylinder and hold counterweight and keep balance position constant.The problem that the method exists is that along with the increase of counterweight weight, after counterweight was in place, the weight of counterweight all was added on the oil cylinder, made oil cylinder bear very big load always, occurred safety problem easily.Other method is; There is few part counterweight self-disassembly and assembly device that elevating ram is installed in the counterweight the inside; The oil cylinder that dependence is installed in the counterweight the inside arrives turntable to the counterweight jacking, holds counterweight with the jacking cylinder cylinder barrel then, and oil pressure is reduced significantly; But this method need connect counterweight elevating ram hydraulic pipe at every turn when counterweight being installed, install extremely inconvenient.
In the hoisting crane self-disassembly and assembly device of some prior aries, be provided with the counterweight blocking device.But these counterweight blocking devices are not the weight of bearing counterweight, but the position of counterweight is limited, and main counterweight weight is still is born by oil cylinder.
The utility model content
To the problem that exists in the above-mentioned prior art, the utility model provide a kind of with mechanical caging the counterweight self-disassembly and assembly device and the hoisting crane of this counterweight self-disassembly and assembly device is housed.The counterweight self-disassembly and assembly device of this band mechanical caging is easy for installation, and can bear counterweight weight, discharges oil cylinder load, improves reliability.
The utility model is realized through following technical scheme: a kind of counterweight self-disassembly and assembly device comprises: turntable; Elevating ram, upper end are fixed on the turntable, and lower ends downward is extended; The counterweight axle sleeve is connected to the lower end of elevating ram with counterweight, and balancer shaft puts and is provided with first locking part; Blocking device is fixed on the turntable, and it is provided with second locking part, and second locking part can cooperate locking with first locking part.
Further, second locking part is that along continuous straight runs extends and clamp movably.
Further, first locking part is horizontally disposed annular groove.
Further, blocking device comprises locked cylinder, and locked cylinder is fixed on the turntable, and the piston rod of locked cylinder is connected with clamp.
Further, locked cylinder vertically is provided with, and blocking device has pipe link, and first end of pipe link and the piston rod of locked cylinder are hinged, and second end and the clamp of pipe link are hinged.
Further, locked cylinder and pipe link are hinged through bearing pin.
Further, locked cylinder is horizontally disposed with, and the piston rod of locked cylinder and clamp direct connection.
And a kind of hoisting crane is equiped with the counterweight self-disassembly and assembly device, and the counterweight self-disassembly and assembly device is above-mentioned counterweight self-disassembly and assembly device.
Through technique scheme, the major advantage of the utility model is: in the counterweight self-disassembly and assembly device, increase mechanical locking, the method for comparing oil cylinder pulling counterweight is safer; And features simple structure, make counterweight more convenient from dismounting.
Description of drawings
The accompanying drawing that constitutes the part of the utility model is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 shows the scheme drawing of counterweight self-disassembly and assembly device of an embodiment of the utility model; And
Fig. 2 shows the scheme drawing of mechanical locking part of counterweight self-disassembly and assembly device of an embodiment of the utility model;
The specific embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
The counterweight self-disassembly and assembly device of an embodiment of the utility model has been shown among Fig. 1.Comprise: turntable 1; Elevating ram 2, upper end are fixed on the turntable 1, and lower ends downward is extended; Counterweight axle sleeve 4 is connected to the lower end of elevating ram 2 with counterweight 5, and counterweight axle sleeve 4 is provided with first locking part; Blocking device 3 is fixed on the turntable 1, and it is provided with second locking part, and second locking part and first locking part are used.
When counterweight 5 was installed, counterweight axle sleeve 4 passed the hole on the counterweight 5, fuses each clump weight; Elevating ram 2 inserts counterweight axle sleeve 4 internal fixation; Promote counterweight to desired location, this moment, turntable 1 upper plate 11 lower planes withstood plane on the counterweight axle sleeve 4, made axle sleeve 4 stop to move up.
The counterweight self-disassembly and assembly device of an embodiment of the utility model has been shown among Fig. 2, mainly is the detail view of blocking device 3 parts.In the present embodiment, second locking part be along continuous straight runs extend and movably clamp 31, the first locking parts be horizontally disposed annular groove 41.Preferably, blocking device 3 also comprises locked cylinder 35, and locked cylinder 35 is fixed on the turntable 1, the hinged pipe link 33 of the piston rod of locked cylinder, and the other end of pipe link 33 and clamp 31 are hinged.Preferably, locked cylinder 35 is hinged through bearing pin 34 with said pipe link 33.The connecting panel 32 that on clamp, also is connected, pipe link 33 is hinged on the clamp 32 through bearing pin 34.Piston rod forms a lever construction between pipe link 33 and the clamp 31.
The operational process of blocking device 3 is following: the clamp 31 that annular groove 41 is aimed on the blocking device 3 on the counterweight axle sleeve 4; The piston rod of locked cylinder 35 elongation then; Promote clamp 31 through pivotally attached connecting rod 33 and get in the annular groove 41, make clamp 31 block counterweight axle sleeve 4, the load that act on the counterweight elevating ram 2 this moment is all born by clamp 31; Elevating ram 2 pressure releasves, locked cylinder 35 lockings.When counterweight 5 was pulled down, at first, elevating ram 2 rod chambers were communicated with oil pressure, made elevating ram 2 hold counterweight axle sleeve 4; Then, the withdrawal of locked cylinder 35 cylinder bars, pulling connecting rod 33 drives clamp 31 and leaves annular groove 41; Then, elevating ram 2 slowly puts down counterweight, and in axle sleeve, produces; Completion is from disassemble and assemble work.
