Two sets of centre hole jacks (1) and a jack (2) are used as vertical lifting equipment. Two sets of horizontal jacks (7), a jack (8) and a counter-force frame (6) are used as horizontal pushing equipment. The two sets of centre hole jacks (1) and the jack (2) are erected on a steel corbel (3) formed by I-beam in a welding mode. A hanging frame (4) is welded on a steel frame. The upper end of a steel wire rope (5) for lifting penetrates through the centre hole jacks (1), and the lower end of the steel wire rope (5) is fixed on the hanging frame (4) on the steel frame. By in-turn lifting of the two sets of centre hole jacks (1) and the jack (2), the steel structure frame is lifted to the mounting elevation.
Description
Technical field
The utility model relates to the construction tool of building operations, especially a kind of large-scale steel structure framework integral lifting apparatus.
Background technology
Overweight in the building operations, heavy-gauge steel structural framing lifting is a difficult problem always, is subject to the restriction of conventional lifting appliance, and crane capacity and precision control all can not apply to the installation exercise of this special component.As adopt many large-tonnage tower cranes or mobile crane, satisfy crane capacity, but aspect economy then far away not as good as native system.
Because steel structure frame adopts square steel column, beam, four limits all need be welded, as adopting again welding behind steel column, the beam segmented in-position, one side then with just can't welding that structure fits, cause constructional difficulties.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, proposes a kind of large-scale steel structure framework integral lifting apparatus.Concrete technical scheme is:
A kind of large-scale steel structure framework integral lifting apparatus adopts 2 groups of centre-hole jacks 1 and jack 2 as vertical-lift equipment, adopts 2 groups of level jack 7, jack 8 and reaction frame 6 as horizontal incremental launching device.
Described 2 groups of centre-hole jacks 1 and jack 2 are erected on the steel corbel 3 that i iron is welded, at steel frame welding suspension bracket 4, lifting is passed centre-hole jack 1 with wire rope 5 upper ends, the lower end is fixed on the suspension bracket 4 on the steel frame, in turn lifting by two groups of centre-hole jacks 1 and jack 2 is promoted to installed height mark with steel structure frame;
After steel structure frame is promoted to installed height mark, described reaction frame 6, jack 7 and jack 8 are installed, push steel structure frame to structural column, the oil cylinder height of meanwhile finely tuning centre-hole jack 1 and jack 2 is adjusted steel structure frame and is reached accurate installation site, at last steel structure frame and structural column are fixed, finished lifting.
Further, above-mentioned reaction frame 6 is to transmit horizontal thrust, and the level when in place as steel structure frame and the parts of vertically-guided.
Further, above-mentioned 2 groups of jack 7 and jack 8 employings are pushed up in turn the mode of stretching and are pushed steel structure frame to the agent structure post.
This device can lift the Huge Steel Open structural framing safely, efficiently, economically and put in place, and is convenient to the accurate adjustment installation site, can not affect steel structure frame assembly unit quality and intensity, also can not affect the construction that is connected and fixed of steel structure frame and agent structure.

Fig. 2 is the positive facade of large-scale steel structure framework integral lifting apparatus.
Fig. 3 is the top view of large-scale steel structure framework integral lifting apparatus.
The specific embodiment
Such as Fig. 1, Fig. 2 and shown in Figure 3, it is the structural representation of the utility model large-scale steel structure framework integral lifting apparatus.
A kind of large-scale steel structure framework integral lifting apparatus adopts 2 groups of centre-hole jacks 1 and jack 2 as vertical-lift equipment, adopts 2 groups of level jack 7, jack 8 and reaction frame 6 as horizontal incremental launching device.
Above-mentioned 2 groups of centre-hole jacks 1 and jack 2 are erected on the steel corbel 3 that i iron is welded, at steel frame welding suspension bracket 4, lifting is passed centre-hole jack 1 with wire rope 5 upper ends, the lower end is fixed on the suspension bracket 4 on the steel frame, in turn lifting by two groups of centre-hole jacks 1 and jack 2 is promoted to installed height mark with steel structure frame;
After steel structure frame is promoted to installed height mark, described reaction frame 6, jack 7 and jack 8 are installed, push steel structure frame to structural column, the oil cylinder height of meanwhile finely tuning centre-hole jack 1 and jack 2 is adjusted steel structure frame and is reached accurate installation site, at last steel structure frame and structural column are fixed, finished lifting.
Concrete form of construction work is:
1. at structural column steel corbel 3 is installed according to actual weight and the length of hoisting steel structure, and at steel corbel two groups of hydraulic feed-through jacks 1 and jack 2 is installed.
2. the steel structure frame that need lift is finished in installation on ground frame welding assembly unit after transporting the scene to, at the hoisting point position mounting suspension 4 of steel structure frame, can adopt and weld or the bolt connection.
3. hydraulic feed-through jack 1 and jack 2, lower end and suspension bracket 4 fixations are passed in the wire rope upper end.Wire rope quantity and specification are chosen according to actual slinging matter weight.
4. the wire rope that will pass first group of hydraulic feed-through jack 1 is fixed, and the beginning jacking is to the movable height of oil cylinder.In this step, the wire rope of second group of hydraulic feed-through jack 2 should unclamp.
5. the wire rope that will pass second group of hydraulic feed-through jack 2 is fixed, and the beginning jacking is to the movable height of oil cylinder.In this step, the wire rope of first group of hydraulic feed-through jack 1 should unclamp.
6. repeated for the 4th, the 5th step until steel structure frame reaches predetermined absolute altitude.
7. reaction frame 6 and two groups of level jack 7 and 8 are installed.
8. first group of jack 7 jacking, second group of jack 8 keeps motionless.After first group of jack 7 jacking puts in place, between second group of jack 8 and reaction frame, place the power transmission cushion block, second group of jack 8 of subsequently jacking regained the oil cylinder of first group of jack 7 simultaneously.
9. after second group of jack 8 jacking puts in place, place the power transmission cushion block between first group of jack 7 and reaction frame, first group of jack 7 of subsequently jacking regained the oil cylinder of second group of jack 8 simultaneously.
10. repeated for the 8th, the 9th step until steel structure frame is pushed to the installation site.
11. by fine setting hydraulic feed-through jack 1 and jack 2, and level jack 7 and 8, so that the steel work accurate positioning is constructed in order to weld with high-strength bolt.
The utility model device construction is simple, and equipment is easy to buying, and hoisting power is strong, and the correction precision is high, and the Huge Steel Open structural framing lifts by crane after assembly unit is finished on the ground support, has avoided segmental hoisting rear welding procedure in place dead angle.Adopt this scheme can lift by crane 400 tons of gross weights, wide 30 meters, high 35 meters steel frames, as increasing suspension centre and equipment, then can lift by crane the steel member of larger weight and size.
