Specific embodiment
With reference to the accompanying drawings and examples the invention will be further described, and embodiments of the present invention are included but is not limited to
The following example.
Embodiment
As shown in Figure 1, 2, a kind of mountain area gallery truss air translation hanging apparatus are present embodiments provided, to solve
Cliffy mountain cannot use a difficult problem for the lifting mode such as crane and pole-climbing.The hanging apparatus mainly include support, sliding framework, cunning
Rope and haulage gear.Support is four column holder posts, is arranged on the two ends of mounting platform.
Sliding framework is made up of column, and its structure is cuboid framework or square framework, in the present embodiment, sliding framework
Constituted with each 2 meters long columns of 219 steel pipe manufacturings of Φ 6, specifically, continuous three at the top of concrete support both sides respectively anchor
Two root posts, column spacing is more than the chord width degree of gallery truss two, and the material that column welded top has crossbeam, crossbeam does not make especially limit
It is fixed, but there should be higher intensity, and crossbeam two ends are welded gusset at column 100mm, offer on gusset and worn for slip rope
The through hole crossed, during installation, slip rope draws along glide direction and is anchored on two through the gusset at the top of sliding framework two ends, slip rope two ends
Hold on adjacent four column holders post, slip rope first fixes one end before fixing, and the other end is tensioned slip rope using jack cucurbit, treats slip rope
With 4 groups of buckles by slip rope fixation after tight, when end frame is the higher single-side stand of height, the anchoring angle of slip rope is preferably not
More than 60 degree, and support 5 need to make of cable wind rope and effectively draw anchor, prevent suspension cable stress rearward end support from capsizing case occurring.
Haulage gear includes hoist engine and fixed pulley two parts in the present embodiment, and the two is separately positioned on the support at two ends
On, and fixed pulley frame is centrally located, and makes hoist engine cable traction line of force try one's best with gallery truss center line consistent, it is ensured that corridor
There is no larger off normal in road truss slipping, cause the problems such as stopping cunning, grab, increase quality safety risk.
The installation of haulage gear is as follows：Install on the column holder of rear four for installing gallery truss and fix a hoist engine,
As the traction power of gallery truss sliding；A fixed pulley, the traction of hoist engine are fixed on the column holder of front four with steel wire rope
When rope and gallery truss connect, first the hoist cable buckle of 4.5m length is fixed on into gallery truss both sides lower edge termination, hauling rope is again
It is connected with the hoist cable centre for fixing, when gallery truss is drawn stress, the string of truss two will be while stress, prevents truss skeleton
Deformed in tension.
Movable pulley is installed, gallery truss is connected by movable pulley with slip rope on slip rope, during construction, gallery truss is being installed
On platform after the completion of assembly, gallery truss is connected with the movable pulley installed on slip rope with jack cucurbit, pulls jack cucurbit, slowly
Slowly by gallery truss integrated hanging 50mm or so, the components such as slip rope system frame, slip rope, jack cucurbit, movable pulley are checked whether
Have deformation, a loosening situation, it is to be checked it is errorless after carry out short distance examination further along and slide, check again for slip rope system frame, slip rope, fall
Whether the components such as chain block, pulley have deformation, loosening situation.After the equal normal work of slip rope system components to be confirmed, manually match somebody with somebody
Close hoist engine and proceed the continuous sliding operation of truss, in slipping when slip rope stress downwarp radian is excessive, use jack calabash
Reed boist truss is to adjust the height of truss, until draw sliding onto steel truss installation site.
Safety devices mainly include railing post, safety rope and cable wind rope in the present embodiment, and its installation is as follows：Make,
Work high above the ground is in sliding, installation process, safety point danger is very big, for the execution conditions of each job step, takes targetedly
Safety measure.Restricted and be easy to the movement of trussmember, turned to by berm width when platform makes, using flexible anti-
Shield, i.e., be welded and fixed railing post on platform every 3m, and flexible protective railing is formed on railing post with manila rope colligation；
Before sliding construction, the single-side stand higher to height carries out drawing anchor using 2 road cable wind ropes to support, prevents single-side stand from receiving side force
Topple；When sliding, installation, a safety rope is set up on sliding framework, sliding operating personnel be hung on safety belt
Thereon.
In the present embodiment, using segmentation while organizing construction, holds the same examination of truss and hang, try under monolithic truss is adopted
It is sliding, after inspection is errorless, will segmentation monolithic truss sliding in place.According to the position of truss center line on support and sliding framework, adjust
The position of whole each section of monolithic truss, after being adjusted in place, interim fixation is done by truss at two ends.Four sections of monolithic steel truss are from far near
Successively sliding in place, fix temporarily after monolithic docking is carried out, then carries out upper and lower string support member installation from centre to two ends.
Fixed and landing slab is installed to mat formation：Truss is slid onto after support position, away from post datum level 100mm when the loosening that blows slowly fall
Chain block, manually prizes gallery truss, makes gallery truss support bolt hole be directed at capital pre-embedded bolt, the slow off the hook of jack cucurbit
It is in place.Suspension column surrounding is held out against using wedge (carving son), and gallery truss is corrected, and makes horizontal displacement and perpendicularity deviation in rule
Break off relations after being welded and fixed after within model and design allowed band.Can carry out follow-up steel platform and mat formation after the completion of this work to apply
Work.
According to above-described embodiment, the present invention just can be well realized.What deserves to be explained is, before above-mentioned design principle
Put, be to solve same technical problem, even if some made on architecture basics disclosed in this invention are without substantial
Change or polish, the essence of the technical scheme for being adopted is still as the present invention, therefore it should also be as the protection model in the present invention
In enclosing.
