Technical field
The present invention relates to leveling supporting leg technical field, specifically a kind of leveling supporting leg fold mechanism can be used for satisfying simultaneously the leveling supporting leg of liftoff requirement and angle of departure requirement, also can be used for the technical field that other need convert straight line motion to rotational motion.
Background technique
The application of engineering machinery more and more widely often all has been equipped with the leveling supporting leg, and for example engineering truck such as concrete mixer, truck with crane all is equipped with the leveling supporting leg; General leveling supporting leg is four, each side two, in order to guarantee the stability of engineering truck after leveling and the needs of gradient leveling; Must the support force of vehicle tyre fully be discharged, so that the leveling supporting leg has enough strokes, but on many cars; Receive the partly influence of the turning radius, liftoff requirement and angle of departure of dress, merely lean on the leveling supporting leg to carry out whole leveling stroke and be difficult to realize, adopt to increase cushion block or reduce angle of departure at present to guarantee that the leveling supporting leg has enough strokes more; If adopt the mode that increases cushion block; Need manually-operable, then can prolong the setup time of engineering truck leveling greatly, can not realize fast leveling; If adopt the mode that reduces angle of departure, then can reduce the passing ability of car.
Summary of the invention
For solving the problems of the technologies described above; The object of the present invention is to provide a kind of leveling supporting leg fold mechanism; Can rotate automatically and lock; To guarantee the needs of angle of departure, liftoff requirement and leveling stroke, can be used for satisfying simultaneously the leveling supporting leg of liftoff requirement and angle of departure requirement, also can be used for the technical field that other need convert straight line motion to rotational motion.
The present invention is achieved through following technological scheme.
Leveling supporting leg fold mechanism of the present invention mainly comprises base, rotating stand, rotational controller, drive pin, positioning seat, body, positioning shaft, locating stud, spring, plug screw, dish spring, induction rod, push rod and bulb; Rotational controller is installed in the lower end of body; It is whole to form a relatively-stationary rotation control unit, is used to control the rotation of rotating stand, and the leveling supporting leg inserts in the through hole that rotates control unit; Its lower end is equipped with positioning seat; Lower end at positioning seat is equipped with locating stud, spring and plug screw successively, in the upper end of positioning seat dish spring, induction rod and push rod is housed successively, and positioning seat is connected through positioning shaft with rotating stand; Drive pin is housed on the rotating stand, and the lower end of rotating stand is slidingly connected through bulb and base.
Compared with prior art, the beneficial effect that the present invention reaches is: 1. the present invention can guarantee that the leveling supporting leg can upwards lift removing the time receiving automatically, has increased the angle of departure of engineering truck, has improved the passing ability of engineering truck greatly; 2. the present invention can straighten to the leveling state automatically in the leveling process, thereby has increased the leveling stroke, reduced the leveling time; 3. the present invention is simple in structure, can change according to real needs, and installing does not have the particular location requirement, and easy to maintenance, easy operating can be widely used on the leveling supporting leg of missile truck highly versatile.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed description, but not as the foundation of the present invention being done any restriction.
Leveling supporting leg fold mechanism of the present invention mainly comprises base 1, rotating stand 2, rotational controller 3, drive pin 4, positioning seat 5, body 6, positioning shaft 7, locating stud 8, spring 9, plug screw 10, dish spring 11, induction rod 12, push rod 13 and bulb 14; Rotational controller 3 is installed in the lower end of body 6; It is whole to form a relatively-stationary rotation control unit; Be used to control the rotation of rotating stand 2, the leveling supporting leg inserts in the through hole that rotates control unit, and its lower end is equipped with positioning seat 5; Positioning seat 5 is along with the relative body 6 of leveling supporting leg can move up and down; Play the effect in joint, locating stud 8, spring 9 and plug screw 10 are housed successively, dish spring 11, induction rod 12 and push rod 13 are housed successively in the upper end of positioning seat 5 in the lower end of positioning seat 5; Positioning seat 5 is connected through positioning shaft 7 with rotating stand 2; Drive pin 8 is housed on the rotating stand 2, and the lower end of rotating stand 2 is slidingly connected through bulb 14 and base 1, plays the effect that long leg stroke, base area surface state carry out accommodation and support that adds.
The working procedure of leveling supporting leg fold mechanism of the present invention is: when the leveling supporting leg moved downward, drive pin 8 moved in the control flume of rotational controller 3, drove rotating stand 2 and rotated counterclockwise; When rotating stand 2 and body 6 in line after, locating stud 8 heads in the pit of positioning shaft 7 under the effect of spring 9; Prevent that rotating stand 2 generations from freely swinging, rotating stand 2 continues to move downward with the leveling supporting leg, after base 1 lands; Rotating stand 2 temporary transient stop motions are until the waist shaped hole of positioning shaft 7 entering positioning seats 5, because positioning shaft 7 has anti-rotating function in waist shaped hole; In a single day positioning shaft 7 gets into waist shaped hole, and rotating stand 2 lands the back under stressing conditions, will limit it and rotate; Simultaneously, positioning seat 5 also can be connected with empty leg detection device, reaches the requirement that empty leg detects through dish spring 11; Behind the stressed active force greater than dish spring 11 of supporting leg, positioning shaft 7 promotes push rod 13 and upwards produces displacement, after driving induction rod 12 produces corresponding displacement amount in the time of push rod 13 change in location; Connect empty leg signal circuit, and this signal is transmitted this corresponding controller; Supporting leg is removed and received is the inverse process that stretches out, and behind the guiding groove of the entering of the guide finger on the rotating stand 2 rotational controller 3, under the guiding of guiding groove, makes the rotating stand 2 of supporting leg upwards folding, removes receipts thereby accomplish supporting leg.
The content of not doing in this specification to describe in detail belongs to related domain professional and technical personnel's known prior art.
