The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1,, a kind of fast from tower crane is installed, comprise metal construction, driver train, safety guard, hydraulic jacking system and electric control system, described metal construction comprises underframe 1, tower body 2, cocked trailer 3, rotating disk 4, tower cap 5, crane arm 6 and equilibrium arm 7, described underframe 1 is fixed on the bottom of tower body 2, tower body 2 one sides are articulated with the end of cocked trailer 3, when tower body 2 is holded up, underframe 1 contacts with ground, and after tower body 2 falls, the liftoff tower body 2 of underframe 1 was horizontal on cocked trailer 3; Described rotating disk 4 is fixed and tower body 2 tops, and described tower cap 5 is fixed on rotating disk 4 tops, and described crane arm 6 and equilibrium arm 7 are articulated with respectively rotating disk 4 both sides, between crane arm 6 and tower cap 5, are connected by front tension bar 8, between equilibrium arm 7 and tower cap 5, are connected by back stay 9; Described tower cap 5 is the mode that the hinged opposite side of a side locks by bearing pin with rotating disk 4 fixed forms, the hinged side of described tower cap 5 and equilibrium arm 7 the same sides, and the hinge-point of equilibrium arm 7 is positioned at the below of tower cap 5 hinge-points.Described tower body 2 is telescopic structure, has three joints.Described underframe 1 is ballast formula rood beam structure.Between described tower body 2 and cocked trailer 3, be provided with overturning oil cylinder 10.
As shown in Figure 2, for the utility model tower body 2 shrinks folding horizontal structural representation on cocked trailer 3, hinge-point by tower body 2 and cocked trailer 3 under the effect of overturning oil cylinder 10 tower body 2 accumbency on cocked trailer 3, equilibrium arm 7 upsets are shelved on tower body 2, and 5 upsets of tower cap are shelved on equilibrium arm 7.
