The specific embodiment
In order to understand the utility model better, below in conjunction with embodiment and accompanying drawing the technical solution of the utility model is described further, referring to Fig. 1 to 3:
A kind of activity operations platform that is used for fast processing steel case beam end opening weld seam by the utility model enforcement, it includes box-shaped service platform 3 and lifting appliance, box-shaped service platform 3 is by framework 12, base plate 11 and safety rope 10 are formed, framework 12 usefulness Φ 35 * 4 steel pipe field welding groups are to forming, framework 12 long 1500mm, wide 1000mm, high 1000mm, framework 12 bottom laying depths are that the steel plate of 4mm is as base plate 11,12 4 sides of framework are that the seizing wire of 9mm connects and to surround safety rope 10 with diameter, be used for support personnel's safety, steel rope one end is fixed, blue bolt and tension are spent in one end utilization.The staff is equipped with operation tool, in box-shaped service platform 3 to constructions such as main weld 6 processing.
Box-shaped service platform 3 then relies on lifting appliance to realize from ground to the lifting of steel case beam 7 lower edges, the top of box-shaped service platform 3 is connected with lifting hook pulley 8, lifting appliance comprises regulates tubing string 5, dead sheave 1, hoist cable 4 and winch 2, regulates steel case beam 7 lower edges that tubing string 5 is arranged on main weld 6 two.Because steel case beam 7 bridges are supported by column truss type 9, when tubing string 5 is regulated in welding, only need operating personal just can arrive the target location by column truss type 9, easy construction need not additionally to set up construction equipments such as scaffold.Regulate tubing string 5 and use as the bracing frame of dead sheave 1, its intensity must meet the demands, so what regulate that tubing string 55 selects for use is the steel pipe of Φ 219 * 8.Regulate the dead sheave 1 of 3 tons of captive joints on the tubing string 5.In order to make box-shaped service platform 3 lifting more steady, hoist cable 4 is all passed in box-shaped service platform 3 both sides, and every side is provided with two lifting hook pulleys 8, and this also just makes adjusting tubing string 5 numbers of 6 liang of head ends of main weld be respectively two.Hoist cable 4 should satisfy requirement of strength, must possess elasticity again, so what hoist cable 4 adopted in the present embodiment is the fiber steel rope, hoist cable 4 head ends are fixed, terminal pile warp dead sheave 1 back be arranged on ground-surface winch 2 and be connected, winch 2 starts the hoist cable 4 of just can reeling, thereby with 3 liftings of box-shaped service platform.In order to improve operating efficiency, a winch 2 lifts by crane three box-shaped service platforms 3 simultaneously, is that 3 tons of winchs 2 are to guarantee enough output torques so winch 2 selects for use.When box-shaped service platform 3 reaches with lifting hook pulley 8 steel case beams 7 lower edges, hoist cable 4 basic maintenance levels, and the length direction that is parallel to steel case beam 7 end opening weld seams 6, by the operation of staff to lifting hook pulley 8, box-shaped service platform 3 can slide along hoist cable 4 front and back, to carry out the processing to whole piece main weld 6, what lifting hook pulley 8 was selected for use is 0.5 ton of pulley of remaining silent.
The utility model use is: the workmen is with equipment to enter box-shaped service platform 3, the terrestrial operation employee starts winch 2, the end of coiling hoist cable 4, hoist cable 4 shrinks box-shaped service platform 3 is risen to construction height, the workmen handles main weld 6 in box-shaped service platform 3, and utilizes lifting hook pulley 8 to slide on hoist cable 4 with processing whole piece weld seam 6, after weld seam 6 disposes, the terrestrial operation employee starts winch 2 hoist cable 4 that comes up, and returns ground.The utility model operation is just clean, easy to use, needs material few, and is safe and reliable, can satisfy main tank beam bottom weld seam 6 fast processing operatings needs.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalence of being done according to the utility model claim changes, and still belongs to protection domain of the present utility model.
