(3) the present invention makes support arm spread length reach more than 6 meters, and outward appearance is beautiful;
(4) the present invention reduces support arm fluctuating cylinder sizes.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the electric control theory figure of the embodiment of the invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, a kind of aloft work work platform leveling mechanism, comprise support arm 1 hinged each other and upper arm 2, the end of support arm 1 is connected with workplatform 8, and the other end of upper arm 2 is connected with principal arm 11.
Upper arm 2 has an anterior extension end 2a, anterior extension end 2a and support arm 1 hinged, the hinge-point A place of anterior extension end 2a and support arm 1 is hinged with support arm connecting rod 3 simultaneously, support arm connecting rod 3 is provided with the first angular transducer 6.
Upper arm 2 is fixed with support arm adjustment oil cylinder 4 in the below of anterior extension end 2a, the support arm adjustment valve rod 4a of oil cylinder 4 and the lower hinge of support arm connecting rod 3 are in B point.The bottom of support arm connecting rod 3 extends along the below of support arm 1, and the lower end of support arm connecting rod 3 is hinged with support arm elevating ram 5, and valve rod 5a and the support arm 1 of support arm elevating ram 5 are hinged.
Workplatform 8 is fixed with platform contiguous block 7, platform contiguous block 7 is provided with the second angular transducer 10.The end of support arm 1 has an overhanging projection 1a, and platform contiguous block 7 is hinged with overhanging projection 1a, and support arm 1 is provided with workplatform adjustment oil cylinder 9 in the below of overhanging projection 1a, the valve rod 9a of workplatform adjustment oil cylinder 9 and the lower end of platform contiguous block 7 hinged.
As shown in Figure 1, in the present embodiment, support arm 1 is two sections of telescopic boom, and in other detailed description of the invention, support arm also can be other Multi-section telescopic support arms, as three sections of telescopic boom, four sections of telescopic boom etc., to reach substantially identical technique effect.
In other detailed description of the invention, principal arm can be Multi-section telescopic principal arm, as two sections of flexible principal arms, three sections of flexible principal arms, four sections of flexible principal arms etc.; Upper arm 2 can be Multi-section telescopic upper arm, as two sections of flexible upper arm, three sections of flexible upper arm, four sections of flexible upper arm etc.
Owing to avoiding support arm elevating ram to be directly installed on upper arm in the present embodiment, therefore avoid support arm and rise and fall 110 ° of scopes and produce the interference of support arm elevating ram, also reduce the cylinder diameter of support arm oil cylinder.
Due to support arm elevating ram and support arm connecting rod and support arm hinged, therefore support arm elevating ram stretches, and can realize support arm at-44 ° ~+66 ° range of motion.
As depicted in figs. 1 and 2, at principal arm or/and when upper arm rises and falls, the first angular transducer detects principal arm or/and upper arm the rises and falls angle signal brought, is transferred to electric controller, electric controller controls the valve rod action of support arm adjustment oil cylinder, makes support arm connecting rod mechanism reversing sense return positive respective angles.
In principal arm fluctuating, upper arm heave, by detecting the first angular transducer signal at support arm connecting rod place, automatically controlled support arm adjustment oil cylinder stretches, and makes the support arm on support arm connecting rod be connected hinge " A " with upper arm and support arm adjusts oil cylinder and support arm connecting rod hinge " B " line vertical ground all the time.
As support arm does not carry out rise and fall, workplatform just can realize levelling function automatically.
As support arm carries out rise and fall, by detecting the second angular transducer signal, automatically controlled workplatform leveling cyclinder stretches, and workplatform just can realize this operating mode levelling function automatically.
As principal arm fluctuating, upper arm fluctuating, support arm fluctuating composite move, respectively by detection support arm connecting rod place angular transducer signal, workplatform angular transducer signal, automatically controlled support arm adjustment oil cylinder is flexible respectively, workplatform leveling cyclinder is flexible, and workplatform just can realize this operating mode levelling function automatically.
Obviously, no matter working arm is under which kind of action operating mode, and workplatform all can keep horizontality.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technical personnels in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
