Abstract
The utility model discloses a combination type pressure bar hanger which comprises an upper pressure bar group. The upper pressure bar group is articulated with a lower pressure bar group, an upper hanging point is arranged on the upper pressure bar group, and a lower hanging point is arranged on the lower pressure bar group. The pressure bar hanger turns the force of slant steel cables between the hanging points and hanging hooks to the inner shaft pressure of a bar member by the way that a hanger with a frame structure is formed by the upper pressure bar and the lower pressure bar which are articulated together, thereby lowering the structure height of the hanger and reducing the structure weight of the hanger and simplifying the bearing force of the hanger. The hanging weight and the hanging height of the hanger are greatly increased, and the safety of hanger installation is greatly improved. Meanwhile, due to the replacement of the middle segment of the pressure bar, the structure improvement of the hanger can be rapidly achieved so as to adapt to the hanging requirement of girder segments with different specifications.
Description
Technical field
The utility model belongs to hanging apparatus, is specifically related to the big segment lifting of a kind of bridge construction middle girder.
Background technology
Traditional truss structure suspender such as Fig. 1 are adopted in beam section lifting at present, and there is following difficulty in it:
One, truss structure suspender require beam section suspension centre quantity many, to adapt to the stressed needs of truss structure.But the many suspension centres that will cause of suspension centre quantity connect difficulty, and unbalance stress, have a strong impact on structure stress safety.
Its two, large-block beam section installation site height adopts the truss structure suspender, it is very little that domestic existing crane barge hangs high affluence.Consider the wave effect that shippping traffic produces, guarantee to lift safety, should reduce spreader height.
Its three, the about 1300t of large-block beam section maximum weight, and the truss structure suspender nearly 300t that conducts oneself with dignity adds up to the nearly 1600t of lift heavy.Near the maximum lift heavy of domestic existing 1600t crane barge, guarantee to lift safety, should alleviate hanger structure weight.
Its four, large-block beam section totally 9 classes, 18, length is 16m～60m, beam segment length and suspension centre arrange and can't unify that the truss structure suspender can't satisfy different size beam section lifting requirements.
Summary of the invention
The purpose of this utility model is to provide a kind of hanger structure height little compound type depression bar suspender, to address the above problem at the defective of above-mentioned truss structure existence.
The technical solution of the utility model is: compound type depression bar suspender, and it comprises the upperpush rod group, the down-pressed pole group that is articulated and connected between the upperpush rod group is established suspension centre on the upperpush rod group, sets suspension centre on the down-pressed pole group.
The described suspension centre of going up is provided with 4 groups, and following suspension centre is provided with 8 groups.
Upperpush rod is connected and composed by at least two pole spares.Down-pressed pole is connected and composed by at least two pole spares.
The utility model is formed the framed structure suspender by the upper and lower depression bar of pivotally attached, and bevelled steel cable force between suspension centre and the suspension hook is converted into axle pressure in the rod member, thereby reduces the hanger structure height, alleviate dead load, and stressed also the obtaining of suspender simplified.The lift heavy of crane barge and hang high affluence and be improved, the lifting safety significantly promotes.Simultaneously, by replacing depression bar interstitial segment, but at high speed is finished the hanger structure transformation, adapts to different size beam section lifting needs.
Description of drawings
Fig. 1 has truss structure suspender scheme drawing now.
Fig. 2 compound type depression bar suspender schematic top plan view.
Fig. 3 compound type depression bar suspender interarea scheme drawing.
Scheme drawing is looked on Fig. 4 compound type depression bar suspender left side.
Fig. 5 upperpush rod and the down-pressed pole scheme drawing that is articulated and connected.
The specific embodiment
As shown in Figure 2, the upperpush rod group is made of two upperpush rods that are parallel to each other 1, and upperpush rod 1 is to be connected to form by bolt 2 by three pair rod spare.Down-pressed pole 3 is made of four down-pressed poles that are parallel to each other 3; Down-pressed pole is connected to form by bolt 4 by three pair rod spare.Down-pressed pole 3 two ends are articulated and connected with two upperpush rods 1 respectively, constitute framed structure.
Shown in Fig. 3,5, establish engaging lug 5 on the upperpush rod 1, set engaging lug 6 on the down-pressed pole 3, be connected hinging supporting shaft 7 between last engaging lug 5 and the following engaging lug 6.Following engaging lug 6 bottoms are provided with down hangs axle 8, is provided with here and hangs axle 8 under two, forms suspension centre down.
As shown in Figure 4, establish the described suspension centre of going up on the upperpush rod 1 and comprise the last hanging scroll of establishing on the upperpush rod 19, link stopper 10 is established at last hanging scroll 9 two ends.
Here go up suspension centre 11 and have 4 groups, following suspension centre 12 has 8 groups.
Compound type depression bar suspender use principle is: arrange cable wire on the upperpush rod suspension centre, be intersected in suspension hook, the down-pressed pole suspension centre is connected with beam section suspension centre, after suspension hook promotes, cable wire around last suspension centre rotate, upperpush rod rotates around down-pressed pole, the inclination angle that cable wire produces between self adaptation suspension centre and the suspension hook.Beam section weight passes to suspension hook by suspender, because the suspender employing is hinged, only has axle pressure in the last down-pressed pole.
Compound type depression bar suspender using method is: combination bolt different length depression bar adapts to different beam section sizes and suspension centre thereof and arranges; Suspender placed treat on the hanging beam section, utilize crane barge to be hooked in tying up rope between suspension centre for a short time, be intersected on the suspension hook; Crane barge plays hook, promotes cable wire, and cable wire rotates around last suspension centre, and upperpush rod rotates around down-pressed pole; Connect suspension centre and beam section suspension centre down, tighten up repeatedly and slightly loosen suspension hook, adjust hoist cable and make each suspension centre stressed even, the lifting beam section is to the installation site then.
This suspender is used for bridge large-block beam section lifting construction, and it is simple in structure, light and handy, stressed clear and definite, but Rapid Combination adapts to the lifting of different size beam section, lifts safe.
