Also be provided with and drive the actuating device that angle changes between the column that main terraced lower plate 21 and main terraced upper plate 22 make winner's ladder lower plate 21, main terraced upper plate 22 and switching bracing frame 11, main terraced lower plate 21 and the terraced upper plate 22 of master are set in parallel;
Also be provided with main ladder round adapter plate 23, be fixed with main ladder round 24 on the main ladder round adapter plate 23, the upper end of main ladder round adapter plate 23 is hinged on the main terraced upper plate 22, the lower end of main ladder round adapter plate 23 is hinged on the main terraced lower plate 21, and main ladder round adapter plate 23 is set in parallel with the column of switching bracing frame 11.
Main ladder round adapter plate 23 is vertical setting with main ladder round 24.On main terraced lower plate 21, be fixed with main terraced guardrail 25.Bottom surface at switching bracing frame 11 is equipped with road wheel 13.
On main terraced lower plate 21, be provided with telescopic oil cylinder 33, on main terraced upper plate 22, slide and be overlapped with aerial ladder lower plate 31, main terraced upper plate 22 is parallel with aerial ladder lower plate 31, and the piston rod of telescopic oil cylinder 33 is hinged on the aerial ladder lower plate 31, and aerial ladder lower plate 31 is provided with aerial ladder upper plate 32;
Also be provided with the aerial ladder adapter plate 34 of marking time, aerial ladder is marked time and is fixed with aerial ladder on the adapter plate 34 and marks time 35, the mark time upper end of adapter plate 34 of aerial ladder is hinged on the aerial ladder upper plate 32, the mark time lower end of adapter plate 34 of aerial ladder is hinged on the aerial ladder lower plate 31, and aerial ladder lower plate 31 is set in parallel with aerial ladder upper plate 32, and aerial ladder lower plate 31 is hinged on the aerial ladder pedestal 36 with the flexible end of aerial ladder upper plate 32;
Also be provided with and drive aerial ladder change that aerial ladder lower plate 31 and aerial ladder upper plate 32 make that angle changes between aerial ladder lower plate 31, aerial ladder upper plate 32 and the aerial ladder pedestal 36 oil cylinder 37 of marking time, the hinge-point line of aerial ladder lower plate 31, aerial ladder upper plate 32 and aerial ladder pedestal 36 and the aerial ladder adapter plate 34 of marking time is set in parallel.
Mark time adapter plate 34 and aerial ladder of aerial ladder marked time and 35 is vertical setting.On aerial ladder lower plate 31, be fixed with aerial ladder guardrail 38.Turret is provided with roller 39 on aerial ladder lower plate 31.
Aerial ladder lower plate 31, aerial ladder upper plate 32 are set in parallel with the hinge-point line of aerial ladder pedestal 36 and the column of switching bracing frame 11.
Drive angle changes between the column that main terraced lower plate 21 and main terraced upper plate 22 make winner's ladder lower plate 21, main terraced upper plate 22 and switching bracing frame 11 actuating device and be the main terraced change oil cylinder 26 of marking time, the piston rod that main ladder becomes the oil cylinder 26 of marking time is hinged on the main terraced lower plate 21, and the afterbody that main ladder becomes the oil cylinder 26 of marking time is hinged on the column of switching bracing frame 11.
During work, become the flexible of the oil cylinder 26 of marking time, make that angle changes between the column of winner's ladder lower plate 21, main terraced upper plate 22 and the bracing frame 11 of transferring by main ladder.Because main terraced lower plate 21 is set in parallel with main terraced upper plate 22, and main ladder round adapter plate 23 is set in parallel with the column of switching bracing frame 11, so main terraced lower plate 21, main terraced upper plate 22, main ladder round adapter plate 23 is hinged to a parallelogram with the column of switching bracing frame 11, when becoming oil cylinder 26 work of marking time, main ladder makes winner's ladder lower plate 21, when angle changes between the column of main terraced upper plate 22 and switching bracing frame 11, main ladder round adapter plate 23 is parallel all the time with the column of switching bracing frame 11, and because the column of switching bracing frame 11 is fixing all the time, so main ladder round adapter plate 23 is parallel with switching bracing frame 11 all the time, again owing to be fixed with main ladder round 24 on the main ladder round adapter plate 23, main ladder round 24 and main ladder round adapter plate 23 vertical settings, so, main ladder round 24 column with switching bracing frame 11 all the time is vertical, when the column of bracing frame 11 of promptly transferring was vertical, main ladder round 24 was horizontally disposed with all the time.It is flexible when marking time oil cylinder 37 work that aerial ladder becomes, and makes aerial ladder lower plate 31 and aerial ladder upper plate 32 stretch out or indentation master ladder upper plate 21, realizes the Telescopic of aerial ladder, and the principle of work of marking time of aerial ladder is identical with the principle of work of above-mentioned main ladder round.
After main ladder becomes oil cylinder 26 startups of marking time, main terraced lower plate 21, main terraced upper plate 22 changes with the column angle of switching bracing frame 11, meanwhile, aerial ladder lower plate 31, aerial ladder upper plate 32 also changes synchronously with the hinge-point line of aerial ladder pedestal 36 and the angle of aerial ladder lower plate 31 or 32 formation of aerial ladder upper plate, because main terraced upper plate 22 is parallel with aerial ladder lower plate 31, aerial ladder lower plate 31, aerial ladder upper plate 32 is set in parallel with the hinge-point line of aerial ladder pedestal 36 and the column of switching bracing frame 11, again because aerial ladder lower plate 31, the hinge-point line of aerial ladder upper plate 32 and aerial ladder pedestal 36 and the aerial ladder adapter plate 34 of marking time is set in parallel, so aerial ladder is marked time adapter plate 34 also with the switching bracing frame 11 column be set in parallel, the column of switching bracing frame 11 is parallel with main ladder round adapter plate 23, adapter plate 34 is parallel with main ladder round adapter plate 23 so aerial ladder is marked time, so, main ladder round 24 and horizontal surface angulation, aerial ladder is marked time and 35 is depended on they and the angulation of the adapter plate of marking time separately with the horizontal surface angulation, when main ladder round 24 vertical with main ladder round adapter plate 23, aerial ladder is marked time and 35 is marked time adapter plate 34 when vertical with aerial ladder, main ladder round 24 and horizontal surface angulation, it is 35 identical with horizontal surface angulation size that aerial ladder is marked time, so, main ladder swing, when aerial ladder stretched, the levelness of marking time above them was consistent.Promptly when the column of switching bracing frame 11 when vertical, main ladder round 24 and aerial ladder mark time 35 when work complete level.
