When the first telescopic driving assembly 6 drives the second casing 31 to move, the third driving belt 77 installed on the bottom surface of the second casing 31 is released to the maximum length for driving, so that the redundant length cannot be continuously provided to compensate the length requirement of the driving belt corresponding to the movement of the second casing 31, and as the above description shows that the power requirements of the first driving mechanism, the second driving mechanism and the third driving mechanism are sequentially reduced, that is, the second telescopic driving assembly 7 can adopt the third driving motor 76 with low power, so that the third driving motor 76 has small body weight and light weight, thereby being convenient for movement.
The direct drive assembly 5 and the first telescopic drive assembly 6 are fixedly installed inside the support housing 1, as shown in fig. 6, two side walls of the support housing 1 are provided with a movable mounting seat 9 at the installation height of the second telescopic drive assembly 7, the movable mounting seat 9 is connected with a drive element 10, the second telescopic drive assembly 7 is fixedly installed on the movable mounting seat 9, and the movable mounting seat 9 is driven by the drive element 10 to move along two side walls of the support housing 1 so as to compensate the movement distance of the second cladding housing 31 driven by the first telescopic drive assembly 6.
That is, in this embodiment, the driving element 10 is used to drive the second telescopic driving assembly 7 to move along two side walls of the supporting housing 1, so as to compensate the moving distance of the first telescopic driving assembly 6 to drive the second wrapping housing 31, and after compensating the moving distance, the second telescopic driving assembly 7 drives the third wrapping housing 41 to extend to the maximum distance by using a belt transmission mode, so that the conveying belt carries out conveying work at the head end of the supporting housing 1 and the tail end of the third wrapping housing 41, and at this time, the conveying distance is the farthest.
According to the bridge frame telescopic driving mechanism of the telescopic machine, all the bridge frame telescopic driving mechanisms of the telescopic machine are arranged in the supporting shell, the working strength of the three driving assemblies is reduced, and the working frequencies of the three driving assemblies are sequentially reduced in an outward-inward mode, so that the telescopic machine which is energy-saving and stable is achieved.
