(5) specific embodiment

Also in conjunction with the accompanying drawings the utility model is further specified below by example:

As Fig. 1, Fig. 2, shown in Figure 3, iron tower of the present utility model is installed with two swing arm loop wheel machines and is comprised base (7), base (7) is gone up body of the tower (10) is installed, body of the tower (10) is by passing through bolted standard knot successively, body of the tower (10) bottom cover one jacking stock (9), be provided with on the jacking stock (9) and also overlapping some frames (11) that adhere on two jacking cylinders (38), adhere to frame (11) by adhering to connecting rod (11) and outer attached building (37) and flexibly connect or being rigidly connected, body of the tower (10) top installs back rotation mechanism (15), swing type mechanism (15) drives by rotary motor, swing type mechanism (15) is gone up the arm (20 and 21) that two symmetric arrangement are installed, and tower cap (30) is installed in the middle of the swing type mechanism (15).

As shown in Figure 5, the luffing steel rope is through luffing deflection sheave (31 and 32), luffing assembly pulley (3) and assembly pulley (13 and 14) many multiplying powers between the assembly pulley (22 and 25) of the assembly pulley (33 and 34) at tower cap (30) top and arm head wear around, realize arm (20) and arm (21) luffing.

As shown in Figure 4, hoist rope is by the deflection sheave that hoists (16,17,18,19,23,26), and lifting pulley group (2) and assembly pulley (13 and 14) are at last at arm (20) and arm 21) between the assembly pulley (24 and 27) of head and the lifting hook pulley group (28 and 29) many multiplying powers wear around.

The swing type mechanism of loop wheel machine (15) adopts the swing type mechanism of common tower machine, can pass through electro-motor or fluid motor-driven.

The jacking stock (9) of loop wheel machine comprises the jacking framework, hydraulic lifting oil cylinder (38), support claw (39), and supporting pumping plant, lifting body adopts the two-sided jacking of common tower machine, can make the loop wheel machine jacking safer, jacking base of frame and base pass through bolted connection, during jacking, start oil cylinder (38) and make and also be provided with on the jacking crossbeam (41) of oil cylinder (38) end on the jacking piece that anchor plate is bearing in the body of the tower outside, make oil cylinder (38) stretch out certain-length, promote a standard pitch from, at this moment support claw (39) can be bearing on following second group of jacking piece of standard knot, regain oil cylinder, this action that circulates is until making whole loop wheel machine upwards promote the distance of a standard knot, by being installed in the standard knot sliding rail (8) on the base (7), standard knot is introduced, connected with the nethermost standard knot of body of the tower (10).Operation can promote a plurality of standard knots successively.

Loop wheel machine is installed: at concrete foundation (1) pre-embedded anchoring bolts and the pre-embedded steel slab of realizing cast, holding-down bolt is connected with base (7), base (7) is connected with jacking stock (9) with body of the tower (10), and pre-embedded steel slab and luffing and deflection sheave group (the 2 and 3) support that hoists are welded to connect.Body of the tower (10) is connected successively by standard knot, body of the tower (10) top is connected by high strength bolt with swing type mechanism (15), body of the tower (10) middle part is installed and is hoisted and luffing deflection sheave group (13 and 14), swing type mechanism (15) is connected with arm (the 20 and 21) bearing pin of symmetric arrangement, be connected with tower cap (30) bearing pin, the luffing steel rope is by the deflection sheave group (3) on basis, the deflection sheave group (13 and 14) at body of the tower middle part, deflection sheave on the tower cap (31 and 32), between the assembly pulley (22 and 25) of the assembly pulley (33 and 34) of tower crown portion and arm head, wear at last around, when realizing luffing and jacking arm (20 and 21) is packed up and close tower cap (30).Hoist rope is through the deflection sheave group (2) on the basis, the deflection sheave group (13 and 14) on the body of the tower, the deflection sheave (16 and 17) on the swing type mechanism (15), the deflection sheave (23 and 26) on the arm, between the assembly pulley (24 and 27) of arm head and lifting hook pulley group (28 and 29), wear at last around.The loop wheel machine jacking, by lifting body whole loop wheel machine promote a standard pitch from, draw and be connected being placed on standard knot on base (7) the standard knot introduction track (8) in advance with body of the tower.It is changeless adhering to during jacking, similar to the lifting principle of common internally climbing tower crane.

Loop wheel machine work: two arms (20 and 21) symmetric arrangement, mutual balance, can hoist synchronously, also can hoist separately, (winch 4 that hoists is two reels, independent drive) also can hoist separately, luffing also can synchronous amplitude, also luffing (luffing winch 5 is two reels, independent drive) makes the installing component of iron tower (37) easier to be in place separately, and revolution can realize that positive and negative 90 degree luffings are in place.

Loop wheel machine dismounting: can be during the loop wheel machine dismounting arm (20 and 21) to tower cap (30) close (iron tower upper opening space is little), start lifting body and fall tower, fall to run in the tower process and adhere to frame (11) dismounting, arm (20 and 21) is luffing by a small margin, can be with suspension hook adhesion frame (11) (adhering to frame can decompose) with adhere to connecting rod (12) and be put into ground, other loop wheel machine that usefulness is installed compared with iron tower is more convenient, can reduce and remove the risk that annex is adhered in the personal height dismounting.Loop wheel machine falls joint until dropping to the body of the tower minimum constructive height, removes with the auxiliary loop wheel machine in ground.The dismounting of two swing arm loop wheel machines can be avoided the risk of high-altitude dismantling arm and tower cap, has solved the difficult problem of other iron tower construction loop wheel machine high-altitude dismountings, improves the work efficiency of the dismounting of loop wheel machine.
