Abstract
The utility model discloses a kind of movable mast formula hoisting crane, comprise the derrick crane main body, the footing foundation that by arm, Shears, base, winch and electric system, are formed, also comprise ballast and oil cylinder, on footing foundation, lay slide rail, base bottom is provided with the chute matching with this slide rail, and base is placed on slide rail; Ballast is configured in base rear portion; Oil cylinder one end is fixed on footing foundation, and the other end is connected with base; Oil cylinder telescopic boom is parallel with slide rail direction on footing foundation, and oil cylinder drives base move and then drive crane main body to slide along slide rail.Basis of the present utility model does not need pre-embedded anchoring bolts, but on basis, arrange several square steel tracks, hoist base is placed directly on basis, thereby base track-movable certain distance under the effect of oil cylinder is adjusted hoisting crane work scope, to adapt to the transhipment work of different goods, the utlity model has novel structure, with low cost, be convenient to install the advantage such as operating range is large.
Description
Technical field
The utility model relates to a kind of hoisting crane, belongs to hoisting crane technical field.
Background technology
Derrick crane have make simple, mounting or dismounting are convenient, hoisting capacity is large, is subject to workyard to limit little feature, hoisting large-size member and while lacking large scale hoisting machinery particularly, more aobvious its preceence of this class weight-lifting equipment.But this large-scale derrick crane need be established more cable wind rope, all face a kind of difficult awkward situation that moves, majority has fixing anchor foundation (as shown in Figure 1), the non-anchoring hoisting crane of minority also just increases counterweight merely but hoisting crane itself is also immovable, and only derrick crane need to be moved forward and backward to the transhipment that several meters of distances can solve some large-scale components in the on-the-spot a lot of situations of transhipment, but because limited these large-scale members that cause of operating range that fixed mast hangs cannot be transported, cause huge economic loss.And its lifting radius of this class is little, very flexible.Therefore, derrick crane is generally used for that member is heavier, hoisting engineering is relatively concentrated, workyard is narrow, and while lacking other suitable large scale hoisting machinery.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and a kind of novel movably derrick crane is provided.
For solving this technical matters, the utility model provides a kind of movable mast formula hoisting crane, comprise the derrick crane main body, the footing foundation that by arm, Shears, base, winch and electric system, are formed, also comprise ballast and oil cylinder, on described footing foundation, lay slide rail, the bottom of base is provided with the chute matching with this slide rail, and base is placed on slide rail; Described ballast is configured in base rear portion; One end of described oil cylinder is fixed on footing foundation, and the other end is connected with base; The telescopic boom of described oil cylinder is parallel with the slide rail direction on footing foundation, and oil cylinder drives base to move and then drives derrick crane main body to slide along the slide rail on footing foundation.
Slide rail on described footing foundation is square steel track.
Slide rail on described footing foundation is many square steel tracks.
Beneficial effect: basis of the present utility model does not need pre-embedded anchoring bolts, but on basis, arrange several square steel tracks, hoist base is placed directly on basis, thereby base track-movable certain distance under the effect of oil cylinder is further adjusted hoisting crane work scope, to adapt to the transhipment work of different goods, be more suitable for growing transhipment or lifting demand, the utlity model has novel structure, with low cost, be convenient to install the advantage such as operating range is large.
Accompanying drawing explanation
Fig. 1 is the derrick crane structural representation of prior art;
Fig. 2 is structural representation of the present utility model.
In figure: 1 arm, 2 Shearves, 3 bases, 4 winchs, 5 ballasts, 6 oil cylinders, 7 footing foundations.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is specifically described.
Figure 2 shows that structural representation of the present utility model.
The utility model bag is drawn together derrick crane main body, footing foundation 7, ballast 5 and the oil cylinder 6 consisting of arm 1, Shears 2, base 3, winch 4 and electric system.
The utility model does not need to make basis and carrys out anchoring derrick crane, but lay slide rail on footing foundation 7, this slide rail can be square steel track, and the number of square steel track is according to calculating concrete layout, and the direction that slide rail is laid is parallel with the direction that needs derrick crane to move.
The bottom of described base 3 is provided with the chute matching with this slide rail, and base 3 is directly placed on slide rail, the friction force while reducing crane movable.
Described ballast 5 is configured in base 3 rear portions, and ballast 5, along with base 3 moves together, occurs toppling while preventing derrick crane work.
One end of described oil cylinder 6 is fixed on footing foundation 7, and the other end is connected with base 3, and type of drive is hydraulic-driven.
The telescopic boom of described oil cylinder 6 is parallel with the slide rail direction on footing foundation 7, and when needs movable mast formula hoisting crane, oil cylinder 6 drives base 3 to move and then drives derrick crane main body to slide along the slide rail on footing foundation 7.
Basis of the present utility model does not need pre-embedded anchoring bolts, but on basis, arrange several square steel tracks, hoist base is placed directly on basis, thereby base track-movable certain distance under the effect of oil cylinder is further adjusted hoisting crane work scope, to adapt to the transhipment work of different goods, be more suitable for growing transhipment or lifting demand.The utlity model has novel structure, with low cost, be convenient to install the advantage such as operating range is large.
The above-mentioned embodiment of the utility model, just casehistory, is not only, all within the scope of the utility model or the change being equal in scope of the present utility model all by the utility model, surrounded.
