Also propose on the other hand a kind of construction machinery and equipment, comprised above-mentioned supporting leg.
Further, supporting leg is fixed on the chassis tail end of construction machinery and equipment.
Supporting leg of the present utility model and construction machinery and equipment, adopt a driving cylinder to realize telescopic boom and folding arm sequentially-operating.And the prior art supporting leg generally need to adopt two driving cylinders to realize that telescopic boom is flexible and folding arm is folding.Therefore the utility model supporting leg not only structure is ingenious, and has saved productive costs, supporting leg is fully flexible and launch bottom-to-top-height and descend, and has met the construction machinery and equipment installation requirement, prevents that supporting leg from stopping that construction machinery and equipment walks on stage and bring potential safety hazard.Adopt inhibiting device to define the end position of telescopic boom, realized that telescopic boom is flexible and folding arm is folding and launched sequentially-operating.Adopt driving cylinder and crossbeam and folding arm two hinge-point lines to be parallel to telescopic arm structure, can solve driving cylinder and drive the flexible power of telescopic boom to reduce, reached energy-conservation purpose.Adopt two fixed arms all to tilt to form the splayed structure to the crossbeam outside, can solve the construction machinery and equipment Area of bearing, increased the engineer machinery operation safety zone.
The accompanying drawing explanation
The accompanying drawing that forms a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the complete deployed condition schematic diagram of supporting leg of the present utility model;
Fig. 2 is the complete contraction structure schematic diagram of supporting leg of the present utility model;
The limit device structure schematic diagram that Fig. 3 is Fig. 1.
The specific embodiment
It should be noted that, in the situation that do not conflict, embodiment and the feature in embodiment in the utility model can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As shown in Figure 1, a kind of supporting leg comprises crossbeam 1, bilateral symmetry at crossbeam 1 is furnished with fixed arm 2, telescopic boom 3, folding arm 4, driving cylinder 5, fixed arm 2 one ends are fixed on crossbeam 1, one end of telescopic boom 3 is positioned at fixed arm 2 inner chambers, and telescopic boom 3 can slide by the length direction along fixed arm 2 in fixed arm 2 inner chambers, and folding arm 4 is hinged with telescopic boom 3, driving cylinder 5 one ends and crossbeam 1 are hinged, and the other end and folding arm 4 are hinged.Natch, telescopic boom 3 also can slide along fixed arm 2 outsides.Driving cylinder 5 can be oil cylinder, can be also cylinder.
When driving cylinder 5 shrinks, supporting leg suspension chassis and upper dress Action of Gravity Field, telescopic boom 3 shrinks to fixed arm 2 inner chambers, break away from ground fully until retract, folding arm 4 is folding to the inside, after folding arm 4 folds into end position, supporting leg is in complete contraction state, as shown in Figure 2.
As shown in Figure 2, when driving cylinder 5 elongation, folding arm 4 launches laterally, and after folding arm 4 is deployed into end position, telescopic boom 3 is under the effect of driving cylinder 5, and telescopic boom 3 stops after extending out to end position.Supporting leg is in complete deployed condition, as shown in Figure 1.
The utility model adopts a driving cylinder 5 to realize the sequentially-operating of telescopic boom 3 and folding arm 4.And the prior art supporting leg generally need to adopt two driving cylinders to realize that telescopic boom is flexible and folding arm is folding.Therefore the utility model supporting leg not only structure is ingenious, and has saved productive costs, supporting leg is fully flexible and launch bottom-to-top-height and descend, and has met the construction machinery and equipment installation requirement, prevents that supporting leg from stopping that construction machinery and equipment walks on stage and bring potential safety hazard.
In order to increase the engineer machinery operation safety zone, two fixed arms 2 of supporting leg are outward-dipping formation splayed structure all.Make the Area of bearing of supporting leg increase, thereby increased the engineer machinery operation safety zone.
As depicted in figs. 1 and 2, when folding arm 4, in launching end position, folding arm 4 aligns with telescopic boom 3, and driving cylinder 5 is parallel to telescopic boom 3 with two hinge-point lines of crossbeam 1 and folding arm 4.Make the force direction of driving cylinder 5 consistent with the flexible direction of telescopic boom 3, prevented from occurring between telescopic boom 3 and fixed arm 2 situation of eccentric wear.
In order to have realized that telescopic boom 3 is flexible and folding arm 4 is folding and to have launched sequentially-operating, inhibiting device 6 is installed on fixed arm 2.As shown in Figure 3, inhibiting device 6 comprises body 60, fixed block 61, movable block 62, set screw 64, spring 63, fixed block 61 is arranged on the inboard of fixed arm 2, for limiting the limit retracted position of telescopic boom 3, body 60 is arranged on fixed arm 2, be provided with groove on telescopic boom 3, movable block 62 1 ends are resisted against in this groove; Spring 63 is positioned at body 60, one ends and is resisted against on movable block 62, and the other end is resisted against on set screw 64.Fixed block 61 is mainly used in stoping telescopic boom 3 to continue to move to fixed arm 2 inner chambers.Carry out the thrust of regulating spring 63 by set screw 64, the order when pressure energy that makes movable block 62 compress telescopic boom 3 guarantees to launch.
The utility model also provides a kind of construction machinery and equipment, as concrete pump truck etc., above-mentioned supporting leg is arranged on the tail end of construction machinery and equipment, because the supporting leg bottom-to-top-height is little, met the construction machinery and equipment installation requirement, prevented that supporting leg from stopping the potential safety hazard that construction machinery and equipment is walked on stage and brought.
