Abstract
The utility model discloses an offshore gantry lifting device with high and low legs, and relates to the field of bridge structure component lifting and mounting devices. The lifting device comprises a low leg system, a high leg system, a truss system and a lifting system, the low leg system is positioned on a bridge floor, the high leg system is positioned in water, the truss system is positioned between the upper ends of the high and low legs, and the lifting system is positioned on the truss system. A needed component is lifted by the aid of the lifting system of the lifting device, horizontally shifted to a position above the bridge floor by the aid of a rail on a Bailey truss and movement of the lifting system and then placed on the bridge floor after reaching the height of the bridge floor, so that the mounting operation of lifting the component from a position under a bridge to the bridge floor is finished, efficiency can be effectively improved, and construction quality and safety can be ensured.
Description
Technical field
The utility model relates to a kind of novel marine height leg gate-type crane gear, especially under the adverse environment condition, will make up by lift up rapidly on ground or the water surface to bridge floor, and can effectively guarantee construction quality and safe equipment.
Background technology
In recent years, along with the continuous increase of national basis construction dynamics, the Oversea bridge construction was also increasing, in the bridge superstructure construction, usually adopt tower crane or bridge floor lifting appliance, construction material is worked winching to bridge floor to satisfy the construction demand, there is following problem in this job practices:
Small-sized tower crane is difficult to satisfy in the Superstructure Construction large member, such as suspension cable, concrete slab etc., the lifting requirement, large-scale tower crane buy or lease expenses all higher, economy is lower.
The safety assurance coefficient is low, and when adopting the bridge floor lifting appliance to play the suspension bridge lower member, the driver is in the sight line blind area, need to command by the commanding, and the boom bridge floor of encorbelmenting is operated, and efficient is lower and have the potential safety hazard that can not estimate.
The bridge floor lifting appliance need to toss about in bed to seek more excellent position at bridge floor and be convenient to retry, and this suitable heavy duty is mobile at bridge floor, easily makes bridge floor produce the crack, even can threaten the structure of bridge, is unfavorable for bridge structure safe.
Therefore, in conjunction with the existing equipment material, produce a kind of novel marine height leg gate-type crane gear according to past construction experiences, with the raising efficiency of construction, and guarantee structural safety and construction quality.
The utility model content
Main purpose of the present utility model is for background present situation situation, provide that a kind of efficiency of construction is high, in the guaranteed bridge construction process of safe mass structural element by the machinery that is transferred under the bridge on the bridge, to guarantee that the bridge lower member is transferred in the bridge floor process, can safely, conveniently lift by crane operation
The utility model mainly comprises following components:
A kind of marine height leg gate-type crane gear is characterized in that, comprises following part:
1) is positioned at low leg system on the bridge floor;
2) the high leg system that is in water;
3) trussing: two ends are positioned over respectively low leg system and high leg system upper end; And
4) tackling system: be located on the trussing and also can walk along trussing.
In preferred embodiment of the present utility model, described trussing is formed by double-deck shellfish thunder spelling.
In preferred embodiment of the present utility model, described high pin system comprises the high leg on the basis and the water surface in the water.
In preferred embodiment of the present utility model, foundation length is 20-30 rice in the water, and the high pin on the water surface is greater than 50 meters.
The utility model is to form an effective integral lifting erection equipment by low leg system, high leg system, trussing and tackling system, finish member by the work progress that is transferred under the bridge on the bridge floor, can effectively raise the efficiency and guarantee construction quality and safety.

The specific embodiment
Referring to Fig. 1 to Fig. 3, the marine height of the utility model leg gate-type crane gear mainly comprises following components:
1) low leg system 1: be positioned at the supporting system on the bridge floor in the door type structure, adopt many steel pipes 11 to be made, an end is anchored on the bridge floor 6, and the other end is used for lattice system 3;
2) high leg system 2: being in water in the door type structure connects high supporting system, is comprised of high leg 21 on basic (not shown) and the water surface in the water.Wherein about 25 meters of foundation length in the water highly reach more than 50 meters more than the water surface, have enough rigidity and supporting capacity, and an end is in water, and the other end is used for lattice system 3;
3) trussing 3: trussing 3 is formed by double-deck shellfish thunder spelling, and two ends are positioned over respectively in low leg system 1 and the high leg system 2, are used for the supporting tackling system and satisfy the demand that the tackling system direction across bridge moves, and guarantee that member can move to the bridge floor top;
4) tackling system 4: a kind of structural element vertical lifting device possesses enough crane capacities and horizontal locomotor activity.
Assembling process of the present utility model is as follows:
(1) utilizes respectively respective material, to basis in the water, connect high leg and low leg carries out blanking.
(2) make low leg 1, and the low leg of moulding and bridge floor are carried out anchoring.
(3) set up basis in the water, then connect high leg 2.
(4) the spelling Bailey truss 3, and with the trussing of spelling moulding respectively with low leg system be connected the leg system and be connected.
(5) tackling system 4 and carry out corresponding debugging and loading test is installed.
(6) member is transferred to door type structure and transfers, utilize tackling system 4 hoisting components to the bridge floor height, then by transverse shifting member is moved to the bridge floor top, then transfer member and make it arrive the bridge floor position.
Single lifting component construction is finished.Repeat (6) step, finish the lifting construction of all the other members.
Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
