Description
Technical field
But the utility model relates to a kind of " eight " font supporting leg of folding and unfolding supporting leg, particularly a kind of construction machinery and equipment of construction machinery and equipment.
Background technology
At present, on construction machinery and equipment, particularly lorry-mounted crane, locomotive crane and car hosit all are equipped with retractable supporting leg, and this supporting leg is generally " H " type supporting leg, and the effect of supporting leg is the support base that increases hoisting crane, improves load-carrying ability.Hoisting crane more than eight tons generally all is equipped with four supporting legs, all around splits.In order to compensate ground-surface inclination in operation place and injustice, increase the stability against overturning of hoisting crane, supporting leg generally can both be regulated height separately, and supporting leg requires firm reliable, acts freely.Supporting leg is overhanging during hoisting crane work lands, and hoisting crane lifts.When travelling, supporting leg is regained, reduced overall dimensions, improve crossing ability, the anti-side of " H " type supporting leg is turned round ability, complex structure, and the hydraulic actuating cylinder quantity of use is many.
The utility model content
The purpose of this utility model is to provide a kind of: it is strong that anti-side is turned round ability, simple in structure, " eight " font supporting leg of the construction machinery and equipment that the hydraulic actuating cylinder quantity of use is few.
The purpose of this utility model is achieved in that this " eight " font supporting leg comprises leg disc (1), movable arm (2), hydraulic actuating cylinder (3), strut (4), supporting leg rocking arm (5), movable arm (2) is socketed in outside the supporting leg rocking arm (5), hydraulic actuating cylinder (3) is connected in movable arm (2) and the supporting leg rocking arm (5), one end is connected with movable arm (2), the other end is connected with supporting leg rocking arm (5), the upper end of supporting leg rocking arm (5) connects to ground, strut (4) is connected between vehicle frame and the supporting leg rocking arm (5), the lower end of movable arm (2) and leg disc (1).
Beneficial effect: owing to adopted such scheme, supporting leg rocking arm, hydraulic actuating cylinder and strut to be installed in respectively on the vehicle frame, supporting leg rocking arm and movable arm are nested together, and the external part of hydraulic actuating cylinder connects movable arm and leg disc, and the other end of strut connects movable arm.The folding and unfolding action of supporting leg is finished by a hydraulic actuating cylinder; The cylinder pushes movable arm is done fore and aft motion, and in the time of motion, because of strut is connected on the movable arm, it is that radius is done spinning movement that movable arm is needed with strut length in telescopic process, to realize the composite move of entire mechanism; Leg disc is to be connected on the movable arm with articulated form in addition, and the bottom surface can contact fully with ground when leg disc lands, and improves stability.It is strong that anti-side is turned round ability, simple in structure, and the hydraulic actuating cylinder quantity of use is few, reached the purpose of utility model.Advantage: this leg structure is simple, dependable performance, and good stability, easy to operate.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model.
Fig. 2 is a motion process sketch of the present utility model.
The specific embodiment
Embodiment 1: should comprise leg disc 1, movable arm 2, hydraulic actuating cylinder 3, strut 4, supporting leg Rocker arm 5, vehicle frame 6 by " eight " font supporting leg, one end of supporting leg Rocker arm 5 is connected with vehicle frame 6, movable arm 2 is socketed in outside the supporting leg Rocker arm 5, hydraulic actuating cylinder 3 is connected in movable arm 2 and the supporting leg Rocker arm 5, one end is connected with movable arm 2, and the other end is connected with the supporting leg Rocker arm 5, and the upper end of supporting leg Rocker arm 5 connects to ground, strut 4 is connected between vehicle frame and the supporting leg Rocker arm 5, the lower end of movable arm 2 and leg disc 1.
The principle of work of " eight " font supporting leg: supporting leg rocking arm, hydraulic actuating cylinder and strut are installed in respectively on the vehicle frame, and supporting leg rocking arm and movable arm are nested together, and the external part of hydraulic actuating cylinder connects movable arm and leg disc, and the other end of strut connects movable arm.The folding and unfolding action of supporting leg is finished by a hydraulic actuating cylinder.The cylinder pushes movable arm is done fore and aft motion, and in the time of motion, because of strut is connected on the movable arm, it is that radius is done spinning movement that movable arm is needed with strut length in telescopic process, to realize the composite move of entire mechanism.Leg disc is to be connected on the movable arm with articulated form in addition, and the bottom surface can contact fully with ground when leg disc lands, and improves stability.
In Fig. 2, hydraulic actuating cylinder is fixed on the vehicle frame, and by the swing (draw in and open) of hydraulic actuating cylinder realization supporting leg, supporting leg reduces the complete machine overall dimensions near the frame beam both sides when receiving leg, improves crossing ability.Each supporting leg can both be regulated height separately during expansion, can adapt to different ground, and in addition the ability turned round of the anti-side of supporting leg of this pattern is better than H type supporting leg." eight " font leg structure is simple, and hydraulic actuating cylinder quantity is few, and dependable performance can be widely used in the various types hoisting crane.
