Abstract
The utility model relates to a swing type outrigger for an automobile crane. The end surface of an outrigger bracket of the automobile crane is welded with a horizontal outrigger shaft forming hinging connection with a vertical outrigger, the periphery of the end surface of the horizontal outrigger shaft is provided with four horizontal outrigger grooves which are uniformly divided, and the periphery of the end surface of the vertical outrigger is provided with eight vertical outrigger grooves which are uniformly divided; a handlebar is provided with four lock ears which are uniformly distributed, the lock ears can be matched with the vertical outrigger grooves and the horizontal outrigger grooves, and the horizontal outrigger shaft can be mutually fixed and locked with a vertical outrigger shaft. When the automobile crane works, the vertical outrigger shaft can be vertically extended. When the automobile runs, the vertical outrigger shaft can be backwards rotated at 45 DEG and then retracted. The vertical outrigger increases the gap with the ground, and greatly improves the road passing ability of the whole automobile.
Description
Affiliated technical field
The utility model relates to a kind of supporting leg on the car hosit, especially a kind of oscillating type supporting leg of car hosit.
Background technology
At present, the supporting leg of hoisting crane is the vertical takeoff and landing (VTOL) formula, does not possess swing ability forward or backward, and the ground Clearance is little, and this has influenced the road through performance of car load greatly.
Summary of the invention
In order to overcome present little shortcoming of car hosit vertical leg ground Clearance, the utility model provides a kind of car hosit oscillating type supporting leg, this oscillating type supporting leg can rotate forward or backward to be packed up fixingly, can increase the ground Clearance greatly, improves the road through performance of car load greatly.
The technical scheme that its technical matters that solves the utility model adopts is: be welded with horizontal support legs axle (9) on the end face that props up leg support (11) of car hosit, it twists with vertical leg (1) and is connected, twice cannelure (6) is arranged on the axial plane circumference of horizontal support legs axle (9), with a bolt (12) is installed on the corresponding vertical leg of cannelure (6) (1), one end of bolt (12) sinks in the groove, can prevent that vertical leg (1) and horizontal support legs axle (9) break away from, on the end face circumference of horizontal support legs axle (9), the horizontal support legs groove (2) that has four roads to divide equally, on the end face circumference of vertical leg (1), the vertical leg groove (5) that has eight roads to divide equally, vertical leg groove (5) can overlap with horizontal support legs groove (2), the uniform lock ear (13) in four roads is arranged on the handle (3), lock ear (13) can match with vertical leg groove (5) and horizontal support legs groove (2), when horizontal support legs groove (2) and vertical leg groove (5) when overlapping, lock ear (13) is by the pressure of spring (8), can embed in the four road grooves, make horizontal support legs axle (9) and vertical leg axle (1) interfix locked, during the car hosit operation, can make vertical leg axle (1) vertical elongated, when this car travels, vertical leg axle (1) 45 that rotates backward is fixedly packed up.
The beneficial effects of the utility model are: owing to adopted such scheme, vertical leg of the present utility model is increased and ground-surface gap, improve the capacity of road of car load greatly, enlarge its range of use, and the utlity model has simple to operate, reliably reach the labour-saving advantage, and manufacturing process is also simple.
