Description
Technical field
The utility model relates to the high-altitude operation platform field, particularly a kind of fly jib of high-altitude operation platform and levelling gear.
Background technology
In modern society, aerial lift device is widely used in the harbour, harbour, and municipal administration, aspects such as infrastructure construction are served the high-altitude with the people and are carried out that street lamp maintenance, high building are cleaned, people etc. is rescued in the high-altitude.The junction of jib and aerial lift device workplatform is installed a fly jib system sometimes, is a kind of small-sized back work arm (abbreviation fly jib), can handle workplatform and do up-and-down movement by a small margin, makes descending operation more accurately, flexibly.Fly jib need be connected with leveling system.Principal arm and fly jib can cause the workplatform run-off the straight when luffing, the safety that reduces operational comfort and threaten operating personal.Therefore, the aloft work vehicle in use need guarantee in real time that the angle of inclination of workplatform is controlled in the scope of correlation standard.Common fly jib and levelling gear are seen Fig. 1,2.
Fig. 1, Fig. 2 are the parallelogram fly jib mechanisms of common band levelling function.The two ends of fly jib can be reduced to four connecting rods, and these connecting rods constitute parallelogram.When 16 elongations of fly jib amplitude oil cylinder, promote boxed rod and rotate up, luffing thereby the drive fly jib makes progress; In like manner, when fly jib amplitude oil cylinder 16 shortens, the downward luffing of fly jib.In the amplitude changing process, workplatform 18 remains level.What Fig. 1 adopted is the tri-joint mechanism levelling gear, and the cylinder barrel end of leveling cyclinder 12 connects jib, and the cylinder bar connects hinge under the fly jib, and when jib made progress luffing, leveling cyclinder 12 shortened respective distance, makes workplatform 18 maintenance levels.What Fig. 2 adopted is four connecting rod levelling gears, and the cylinder barrel end of leveling cyclinder 12 connects jib, and the cylinder bar connects connecting rod 19, and an end of connecting rod 20 connects connecting rod 19, and the other end connects hinge under the fly jib.When jib made progress luffing, leveling cyclinder 12 shortened respective distance, makes workplatform 18 maintenance levels.
The version of this fly jib and levelling gear is fairly simple, and weight is lighter.But this structure is subjected to the restriction of parallelogram principle, has increased considerably the car load length of aerial lift device.In addition, levelling range is limited, generally at 90 °～100 °.
Summary of the invention
The utility model purpose: the purpose of this utility model provides a kind of fly jib system that is applied to the band levelling gear of aerial lift device, can go back to the principal arm bottom, and luffing does not take car load length simultaneously in the larger context.
Technical scheme: a kind of formula of turning back fly jib system with levelling function is provided.The fly jib steel structure of the described formula fly jib system of turning back is point articulated in the upper end of platform Connection Block by the R on it, the lower end of platform Connection Block and rod hinge connection are in the A1 point, the other end of connecting rod and connecting plate are articulated in the A2 point, the other end of connecting plate and fly jib steel structure are articulated in the Q point, hinged and the O point of one end of leveling cyclinder and fly jib steel structure, the other end and connecting plate are articulated in the A3 point, and an end of fly jib amplitude oil cylinder connects jib, and the other end and fly jib steel structure are articulated in the P point.
Wherein, on the platform of the described formula fly jib system of turning back angular transducer and leveling control module are set; Described leveling control module control leveling cyclinder is flexible.
The levelling gear scope of fly jib of the present utility model mechanism surpasses 170 ° (as Fig. 3, Fig. 5), has covered 100 ° and 70 ° of telescopic boom luffing of fly jib luffing.For make leveling cyclinder easily layout in the box-structure of fly jib, and the stroke with minimum satisfies very big leveling angle, therefore adopt connecting plate to replace connecting rod mechanism, shortened the stroke of leveling cyclinder, satisfy the needs of big leveling angle with little stroke, the maximum weighted of leveling cyclinder and field of load is less, pendulum angle is less in the whole leveling process, help the oil cylinder raising in service life, and can seal as far as possible the less box-structure that makes of the influence of fly jib box-structure, the fly jib stability of structure significantly improves.
Beneficial effect: the utility model compact conformation, fly jib can be gone back to the principal arm bottom under the state that returns the vehicle to the garage and knock off, and makes full use of the space, helps shortening car load length, is applicable to the in-vehicle aerial lift device that is subjected to limitation of length.
