Further, the rope chain bar 27 of stretching is provided with chain detection apparatus；The chain detection apparatus can real-time detection phase The state of chain is closed, when related chain occurs fracture or exceeds default loosening value, which can send alarm signal, come true with this The safety in utilization of the flexible transmission component 2 is protected, and then guarantees the personal safety of operator and other related personnel.Specifically , chain detection apparatus can be located at and stretch one end that rope chain bar 27 is connected with basic arm 21.

Preferably, the basic arm 21, two joint arms 22 and three joint arms 23 are all preferably hollow structure, certainly, described basic Arm 21, two joint arms 22 and three joint arms 23 are not limited to internal for hollow structure, and which is alternatively its that can realize meeting aforementioned condition His structure.

Further, the hollow structure inside of the basic arm 21, two joint arms 22 and three joint arms 23 constitutes telescopic cavity, described Telescopic oil cylinder 24, the first sprocket wheel 25, the second sprocket wheel 26, stretch rope chain bar 27 and return rope chain bar 28 all in the telescopic cavity；Its Can make the more compact structure of this flexible transmission component 2, and then reduce the abrasion of associated components and slow down which is aging, extend its use Life-span, and also maintenance and frequency of maintenance can be reduced, while keeping in repair, safeguarding more convenient, maintenance and maintenance cost are relatively low, separately Outward, can also reduce to a certain extent making related personnel's to touch injured probability by mistake because above-mentioned associated components expose outside.When So, by telescopic oil cylinder 24, the first sprocket wheel 25, the second sprocket wheel 26, stretch rope chain bar 27 and return the part such as rope chain bar 28 and be located at telescopic cavity (i.e. on the outer wall of basic arm 21, two joint arms 22 and three joint arms 23) is also feasible outward.

To sum up, as expansion link 242 is affixed on basic arm 21, therefore when by appropriate liquid media drive cylinder barrel When 241, cylinder barrel 241 can drive two joint arms 22 to move (on the basis of the direction that relevant drawings in Figure of description are put) in the lump upwards It is dynamic, so that two joint arms 22 are stretched out from the upper end of basic arm 21, and then by stretching the gearing of rope chain bar 27 and the first sprocket wheel 25 Three joint arms 23 are pulled to stretch out from the upper end of two joint arms 22, with infusion fluid medium is continued in cylinder barrel 241, two joint arms 22 and three are saved Arm 23 can continue upward end and extend, until it reaches required shift motion or maximum preset stroke；Wherein, in this process, One sprocket wheel 25 is equivalent to a movable pulley so that three joint arms 23 are equal to 241 shift motion of cylinder barrel relative to the displacement of basic arm 21 2 times of (i.e. displacement of two joint arms 22 relative to basic arm 21), so have and are easy to a certain degree improving flexible stroke.

When 244 oil-feed of rod chamber in cylinder barrel 241 is made by the hollow structure 247 in expansion link 242,241 meeting of cylinder barrel Two joint arms 22 are driven to move down in the lump, so that two joint arms 22 are retracted from the upper end of basic arm 21, and then by returning rope chain bar 28 And second the gearing of sprocket wheel 26 three joint arms 23 can be pulled to bounce back in two joint arms 22, enter with lasting in expansion link 242 Oil, two joint arms 22 can continue to lower end to bounce back with three joint arms 23, until it reaches required retraction degree is fully retracted in place；Its In, in this process, the second sprocket wheel 26 is equivalent to a movable pulley so that three joint arms 23 are equal to relative to the displacement of basic arm 21 2 times of 241 shift motion of cylinder barrel (i.e. displacement of two joint arms 22 relative to basic arm 21).

Specifically, comprehensive Fig. 1 and other relevant drawings, the three joint arms 23 are real with operating board 3 by expansion joint assembly 5 Now it is hinged, i.e., three joint arms 23 are hinged with the outer arm 51 on expansion joint assembly 5, the inner arm 52 and operation on expansion joint assembly 5 Platform 3 connects, the expansion joint assembly 5 have be easy to operating board 3 further realize in the horizontal direction it is a certain degree of extension and Retraction；The basic arm 21 is hinged with car body 1 by support arm 4, i.e., basic arm 21 is hinged with support arm 4, support arm 4 and car body Associated components on 1 are flexibly connected；In addition, amplitude oil cylinder 6 is provided between basic arm 21 and support arm 4, which can cause basic arm 21st, support arm 4 and the amplitude oil cylinder 6 being connected with each other with which also constitute a stable triangular structure, and then cause the high-altitude Job platform is in operation with higher stability and safety.

When aerial work platform need to rise arm operation, two joint arms 22 in the flexible transmission component 2 of control are stretched with three joint arms 23 Go out, now, synchronously can stretch out under the drive of three joint arms 23 with the operating board 3 of the connection of flexible transmission component 2, meanwhile, it is also controllable Make related amplitude oil cylinder 6, support arm 4 and expansion joint assembly 5 to adjust extension angle or the position of associated arm, until operation Platform 3 reaches default operating position or maximum extension stroke.

In the same manner, two joint arms 22 and three joint arms when aerial work platform need to receive arm operation, in the flexible transmission component 2 of control 23 retractions, now, synchronously can be bounced back under the drive of three joint arms 23 with the operating board 3 of the connection of flexible transmission component 2, meanwhile, also Can control related amplitude oil cylinder 6, support arm 4 and expansion joint assembly 5 to adjust angle or the position of associated arm, until operation Platform 3 bounces back to default operating position or original non-extension state.

Additionally, referring to accompanying drawing 20, another embodiment of aerial work platform of the present utility model, the reality are there is disclosed The difference that example is applied with above-described embodiment is：Support member between the flexible transmission component 2 and expansion joint assembly 5 is Amplitude oil cylinder 57, i.e., substitute the one-level leveling associated components in above-described embodiment with the amplitude oil cylinder 57；The 3rd leveling oil Cylinder 58 is provided with the angular transducer 59 coordinated with the 3rd leveling cyclinder 58 using electric leveling mode, the oscillating cylinder 33, Hydraulic leveling mode in above-described embodiment in two grade leveling is substituted with the electric leveling mode.

During work, can be by the flexible come real of the amplitude oil cylinder 57 between the flexible transmission component 2 and expansion joint assembly 5 The luffing up and down of existing expansion joint assembly 5；Can be by the flexible leveling to realize operating board of the 3rd leveling cyclinder 58, it is ensured that behaviour Make platform and be in horizontality all the time.

Specifically, a certain position of operating board 3 is preset as zero-bit by the angular transducer 59 on oscillating cylinder 33, In 5 amplitude changing process of expansion joint assembly, the angular transducer 59 can transmit the signal of telecommunication to corresponding controller, and controller receives letter Corresponding control instruction can be sent after number, to control the 58 flexible leveling so as to realize operating board of the 3rd leveling cyclinder, i.e. control behaviour Make platform 3 and be in default zero-bit all the time.

Although having been illustrated with some exemplary embodiments of the present utility model above, those skilled in the art will Understand, in the case of without departing from principle of the present utility model or spirit, these exemplary embodiments can be made a change, this The scope of utility model is limited by claim and its equivalent.
