Which is the most stable?
With the rapid development of China's economy, the demand for high altitude operating vehicles is rising rapidly。 There are many kinds of lifting and lifting of the high altitude operating car, and the height of the operation is from more than ten meters to dozens of meters。 Next, I will tell you which of the most stable Guizhou high altitude operating cars。
Self leveling platform is a platform as early as the most simple structure of the platform, the center of gravity directly beneath the work platform is connected with the arm rotation hinge point, also near the bottom, so that the platform can automatically lift in any case to maintain the level of state based platform and gravity load。 This method has the advantages of simple structure, light weight, convenient maintenance and low cost, but easy to shake, especially when the position change of operating personnel in the platform when the platform moved, operators have the feeling of insecurity, so in the platform to the operation position to use locking mechanism to prevent shaking, difficult to operate, use only in the low work, high technical performance and low operation car, now has been less used。 Parallel four connecting rod leveling mechanism parallel four connecting rod leveling mechanism consists of one or more groups of parallelogram linkages。 The leveling process is continuous and has a reliable characteristic。 And in the actual application itself can be used as a side of the parallelogram, so the structure is relatively simple。 The disadvantage is that the parallel four bar linkage can only be arranged outside the arm, and the structure is not compact。 Due to the limitation of parallel four links, the working angle range between the arms is less than 180。
A chain wheel leveling mechanism chain wheel leveling mechanism is composed of parallel four link leveling mechanism evolved, when the jib luffing, chain drive forced aerial vehicle changes direction corresponding point of view, no matter how can guarantee the arm lifting platform at the state level. The working angle of the chain chain wheel leveling mechanism is larger than that of the parallel four connecting rod leveling mechanism, and the working angle between the arms is more than 180. There are also chains and sprockets which are installed inside the arm, easy to install, adjust and maintain. The leveling mechanism has the characteristics of simple structure, low price and high accuracy. It is suitable for the telescopic boom type operating vehicle. But the disadvantage is that there will be lagging phenomenon, and the lag phenomenon will be more obvious with the increase of height.
