2, the large-scale truss deadweight needing lifting is excessive, and the handling ability of loop wheel machine cannot be born.
3, the suspension centre needing the large-scale truss of lifting is limited by execution conditions, is positioned at the position that loop wheel machine cannot be reached.
Even if lifting construction can be carried out by loop wheel machine, after large-scale truss is in place, still need to immediately it be fixed temporarily, generally adopt welded still pipe or set up the mode of scaffold, not only work consuming consuming time time fixing, after truss structure is finally fixing, the synchronization unloading of temporary support, synchronization are removed and are also bothered very much.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that the tool-type lifting of a kind of large-scale truss structure and discharge mechanism, can be made by batch production, tool degree is high, install, dismantle quick facility, construct simple and convenient, and can repeatedly recycle.
The purpose of this utility model is achieved in that tool-type lifting and the discharge mechanism of a kind of large-scale truss structure, props up support component including one group of main arm of cruciform shape with four groups that are fixed on concrete capital;The main arm of described cruciform shape includes two root length I-steel and four groups of pulleys, and the two perpendicular arranged crosswise of root length I-steel also fix connection, and four groups of pulleys are connected to four ends of the main arm of cruciform shape; Four groups support modular support in the lower section of the main arm of cruciform shape, often group support component all includes short pair of I-steel of a joint and two endowels, the upper end of two endowels is all welded with short pair of I-steel, four groups are propped up wherein two short pair of I-steel of joint and root length I-steel connection in support component, and other two short pair of I-steel of joint are connected with another root length I-steel.
Operating procedure:
The operating procedure of tool-type lifting:
1, astrosphere bearing being fixed on capital, in astrosphere bearing surrounding, four groups of n shapes prop up the angle steel of 8 foothold places pre-buried certain altitudes respectively of support component (a short pair of I-steel of joint and two endowels form n shape)
2, prop up support component first with four groups of n shapes of tower crane handling, the tubing string that each n shape props up support component is inserted in pre-buried angle steel respectively, makes n shape prop up support component and be fixed
3, the recycling tower crane main arm of handling cruciform shape props up on support component to four groups of n shapes, the I-steel of four direction is respectively rested on each n shape prop up support component top spacing in, meanwhile, prop up both support components laminating position high-strength bolt in the main arm of cruciform shape and n shape to fix
4, being put down by the steel wire rope on pulley, one end fixes with the large-scale truss that need to lift, and the hoist engine that the other end controls with computer fixes
5, make each pulley work by computer Synchronization Control hoist engine, operator and truss are promoted to around astrosphere bearing together, truss is respectively welded with astrosphere bearing and is connected, so far complete hanging of truss is risen and be connected
Tool-type unloading and the operating procedure removed:
1, truss welding acceptance(check), reaches off-loadable condition
2, with Calculation Anaysis for Tunnel Structure for foundation, by computer Synchronization Control, slow releasing hoist engine carries out substep unloading
3, after having unloaded, first remove the main arm of cruciform shape and n shape and prop up support component and respectively fit the high-strength bolt at position, hang successively according still further to order from top to down and tear the main arm of cruciform shape open and four groups of n shapes prop up support component, finally cut off pre-buried angle steel
By above operation, this utility model has the following characteristics that
1, itself is namely as lifting device, again as discharge mechanism, decreases much unnecessary input, simplifies operation routine, remarkable in economical benefits
2, batch production processing, it is to avoid what on-the-spot processing brought manually have high input, makes place takies space, job site, many, the problem such as waste of material is serious consuming time
3, tool assembles, and structural safety is reasonable, and lifting is quick convenient, and recycling rate of waterused is high
4, replaced traditional artificial lifting jack unloading by the unloading of computer Synchronization Control, in place precisely, safe and efficient.
As improvement of the present utility model, at four angle welding angle steel that two root length I-steel intersect, to strengthen its globality.
As further improvement of the utility model, above two root length I-steel infalls, weld a mast post, weld oblique tubing string to four ends of the main arm of cruciform shape respectively at the top of mast post, be similarly its globality of reinforcement.
As further improvement of the utility model, all welding a pair limit steel bar at the upper surface often saving short pair of I-steel, long I-steel is spacing to be arranged between every pair of limit steel bar. Ensure that the main arm of cruciform shape when mounted can be precisely in place, stop to prop up support component and the main arm of cruciform shape due to n shape and be not reliably connected and the serious problems that cause a support arrangement unstability to be decayed.
As further improvement of the utility model, often transverse weld reinforced steel between two endowels of group support component, strengthens n shape and props up the globality of support component.
