During for making support arm rise and fall, remaining to leveling work platforms, described work platforms is fixed with platform contiguous block；Described platform contiguous block is provided with the second angular transducer；
The end of described support arm has an overhanging projection；Described platform contiguous block is hinged with overhanging projection；Described support arm adjusts oil cylinder at the work platforms that is arranged below of described overhanging projection；It is hinged with the lower end of described platform contiguous block that described work platforms adjusts the valve rod of oil cylinder.
It is also preferred that the left described support arm is Multi-section telescopic support arm.
It is also preferred that the left described upper arm is Multi-section telescopic upper arm.
The invention has the beneficial effects as follows:
(1) present invention is when the folding arm of multi-joint and Multi-section telescopic arm, can realize work platforms leveling；
(2) present invention can make support arm undulation angle reach 110 °；
(3) present invention makes support arm spread length reach more than 6 meters, and outward appearance is beautiful；
(4) present invention reduces support arm elevating ram size.
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:
The platform erection mechanism as it is shown in figure 1, a kind of work high above the ground works, including support arm 1 mutually hinged and upper arm 2, the end of support arm 1 is connected to work platforms 8, and the other end of upper arm 2 is connected with principal arm 11.
It is hinged with support arm 1 that upper arm 2 has an anterior extension end 2a, anterior extension end 2a, and the pin joint A place of anterior extension end 2a and support arm 1 is hinged with an arm link 3 simultaneously, and an arm link 3 is provided with the first angular transducer 6.
Upper arm 2 is fixed with support arm and adjusts oil cylinder 4 in the lower section of anterior extension end 2a, and support arm adjusts the valve rod 4a of oil cylinder 4 and the lower hinge of an arm link 3 in B point.Propping up bottom the extending below along support arm 1 of arm link 3, the lower end of an arm link 3 is hinged with support arm elevating ram 5, and the valve rod 5a of support arm elevating ram 5 is hinged with support arm 1.
Work platforms 8 is fixed with platform contiguous block 7, and 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 adjusts oil cylinder 9 at the work platforms that is arranged below of overhanging projection 1a, and it is hinged with the lower end of platform contiguous block 7 that work platforms adjusts the valve rod 9a of oil cylinder 9.
As it is shown in figure 1, in the present embodiment, support arm 1 is two sections of telescopic boom, in other detailed description of the invention, support arm is alternatively other Multi-section telescopic support arms, such as three sections of telescopic boom, four sections of telescopic boom etc., to reach essentially identical technique effect.
In other detailed description of the invention, principal arm can be Multi-section telescopic principal arm, such 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, such as two sections of flexible upper arm, three sections of flexible upper arm, four sections of flexible upper arm etc..
Owing to the present embodiment being avoided support arm elevating ram be directly installed on upper arm, therefore avoid support arm and rise and fall 110 ° of scopes and produce support arm elevating ram and interfere, also reduce the cylinder diameter of support arm oil cylinder.
Owing to support arm elevating ram is hinged with an arm link and support arm, therefore support arm elevating ram stretches, it may be achieved support arm is 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 that brings, it is transferred to electric controller, electric controller controls support arm and adjusts the valve rod action of oil cylinder, makes support arm linkage opposite direction return positive respective angles.
In principal arm fluctuating, upper arm heave, by detecting the first angular transducer signal at an arm link place, automatically controlled support arm adjusts oil cylinder and stretches, and makes the support arm in an arm link be connected hinge " A " with upper arm and support arm adjusts oil cylinder and arm link hinge " B " line vertical ground all the time.
Do not carry out rise and fall such as support arm, work platforms just can be automatically obtained levelling function.
As support arm carries out rise and fall, by detecting the second angular transducer signal, automatically controlled work platforms leveling cyclinder stretches, and work platforms just can be automatically obtained this operating mode levelling function.
Such as principal arm fluctuating, upper arm fluctuating, support arm fluctuating composite move, respectively through detection arm link place angular transducer signal, work platforms angular transducer signal, automatically controlled support arm adjustment oil cylinder is flexible respectively, work platforms leveling cyclinder is flexible, and work platforms just can be automatically obtained this operating mode levelling function.
Obviously, no matter working arm is under which kind of action operating mode, and work platforms all can keep level.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work.Therefore, all technical staff in the art, all should in the protection domain being defined in the patent 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.
