Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described, and embodiments of the present invention include but not limited to the following example.
Embodiment
As shown in Figure 1, 2, present embodiments provide a kind of mountain area gallery truss air translation hanging apparatus, in order to solve the difficult problem that cannot use the lifting mode such as crane and pole-climbing in cliffy mountain.This hanging apparatus mainly comprises support, slippage framework, slip rope and haulage gear.Support is four column holder posts, is arranged on the two ends of mounting platform.
Slippage framework is made up of column, its structure is cuboid framework or square framework, in the present embodiment, the each 2 meters long columns of slippage framework Φ 219 steel pipe manufacturing 6 are formed, specifically, continuous three across each anchoring two in both sides, concrete support top root post, column spacing is greater than gallery truss two string width, column welded top has crossbeam, the material of crossbeam is not particularly limited, but higher intensity should be had, crossbeam two ends are apart from column 100mm place welding gusset, gusset offers the through hole passed for slip rope, during installation, slip rope is through the gusset at top, slippage framework two ends, slip rope two ends are drawn along glide direction and are anchored on the adjacent four column holder posts in two ends, first one end is fixed before slip rope is fixing, the other end adopts jack cucurbit by slip rope tensioning, after slip rope tensioning with 4 groups of buckles by slip rope fixation, when end frame is highly higher single-side stand, the anchoring angle of slip rope should be not more than 60 degree, and support 5 need make of cable wind rope and effectively draws anchor, prevent suspension cable stressed rearward end support generation capsizing case.
In the present embodiment, haulage gear includes hoist engine and fixed pulley two parts; the two is separately positioned on the support at two ends; and fixed pulley frame is arranged between two parties; make hoist engine cable traction line of force as far as possible consistent with gallery truss center line; guarantee, in gallery truss slipping, larger off normal does not occur; cause problems such as stopping cunning, grab, increase quality safety risk.
The installation of haulage gear is as follows: install on rear four column holder installing gallery truss and fix a hoist engine, as the traction power of gallery truss slippage; Front four column holder fixes a fixed pulley with wire rope, when the drag cable of hoist engine is connected with gallery truss, first the hoist cable buckle that 4.5m is long is fixed on lower edge termination, gallery truss both sides, drag cable is connected again with in the middle of the hoist cable fixed, when gallery truss is pulled stressed, truss two string will be simultaneously stressed, prevent truss skeleton deformed in tension.
Slip rope is provided with movable pulley, gallery truss is connected with slip rope by movable pulley, during construction, gallery truss on mounting platform assembled complete after, with jack cucurbit, gallery truss is connected with the movable pulley that slip rope is installed, pull jack cucurbit, slowly by unsettled for gallery truss integral about 50mm, check slip rope system frame, slip rope, jack cucurbit, whether the components such as movable pulley have distortion, the situation of loosening, to be checked errorless after to carry out forward short distance examination more sliding, again check slip rope system frame, slip rope, jack cucurbit, whether the components such as pulley have distortion, the situation of loosening.After slip rope system components to be confirmed all normally works, hand fit's hoist engine proceeds the operation of truss transitional care, in slipping when slip rope stressed downwarp radian is excessive, with jack cucurbit boist truss to adjust the height of truss, until traction slides onto steel truss installation site.
In the present embodiment, safety device mainly comprise railing post, safety rope and cable wind rope, its installation is as follows: in making, slippage, installation process, be work high above the ground, safety point danger is very large, for the execution conditions of each job step, takes safety measure targetedly.Platform make time by berm width restriction and be convenient to trussmember movement, turn to, all adopt flexible protective, namely on platform, be welded and fixed railing post every 3m, on railing post, form flexible protective railing with manila rope colligation; Before sliding construction, to highly higher single-side stand, adopt 2 road cable wind ropes to draw anchor to support, prevent single-side stand from toppling by lateral force; When slippage, installation, slippage framework sets up a safety rope, safety belt is hung thereon by slippage operating personnel.
In the present embodiment, adopt segmentation simultaneously organizing construction, hold under monolithic truss is adopted the same examination of truss hang, try sliding, check errorless after, by place for the slippage of segmentation monolithic truss.According to the position of truss center line on support and slippage framework, adjust the position of each section of monolithic truss, after adjusting to the right place, truss is done at two ends temporary fixed.Slippage is in place successively from far near for four sections of monolithic steel trusss, carries out monolithic docking after temporary fixed, then carries out the installation of upper and lower string support member by centre to two ends.
Installation is fixed and landing slab is mated formation: after truss slides onto support position, slowly loosens jack cucurbit, manually prize gallery truss apart from during post datum 100mm, and make gallery truss support bolt hole aligning capital pre-embedded bolt, the slow off the hook of jack cucurbit is in place.Suspension column surrounding adopts wedge (carving son) to hold out against, and corrects gallery truss, breaks off relations after being welded and fixed after making horizontal movement and perpendicularity deviation within specification and design allowed band.Follow-up steel platform pavement construction can be carried out after this work completes.
According to above-described embodiment, just the present invention can be realized well.What deserves to be explained is; under prerequisite based on above-mentioned design principle; for solving same technical problem; even if some making on architecture basics disclosed in this invention are without substantial change or polishing; the essence of the technical scheme adopted is still the same with the present invention, therefore it also should in protection scope of the present invention.
