Embodiment
Electricity coaling wharf screening system mounting process, construction procedure is followed successively by: sieves installation, the sizing screen equipment hoisting of tower steel construction and scrapes trigger and installs,
(1) installation of tower steel construction is sieved:
A. the lifting of steel post: prepare before post lifting: treat that spot inspection is qualified, after stacking and traffic route are determined, namely embedded board is checked, the axis of pre-embedded bolt, planeness, absolute altitude, examine, measure qualified after, base nut under post is screwed on pre embedded bolt, with spirit-leveling instrument base nut leveling to same level, and suitably fixed, automobile is adopted to lift with rotational method during lifting, after the front preparation work of lifting is ready, first carry out examination to hang, sling when one end height is 100 200 and stop hanging, check the verticality of rigging stability and crane stability and steel post, then crane is commanded slowly to decline, with two transit instruments centrally axis become 90 degree of placements, adjustment position is also debugged, to correct post position and verticality, slowly transfer after column base plate and embedded board cross centre line position alignment, control post verticality and off centering with transit instrument simultaneously, operator winch to after above bolt at steel post, stand separately good position, hold suspension column by the pre-opened hole alignment bolt on suspension column plate, it is inserted into, the ditch that falls is stopped when pillar is down on setting nut, pillar is prized with crowbar, make its center line alignment basis center line, and tighten suspension column nut, reach secure side and can extract suspension hook. for the column of single root unstable structure, wind cable temporary protection measure must be added. lifting group must be divided the work clearly before lifting, and utensils such as measuring, lift, be fastening is complete, and each one does his duty for each quality safety slip-stick artist of crane, commander, measurement, contraposition, colligation and site operation, and to reduce idler close as far as possible.
B. the lifting of girder steel: after steel post has lifted, before steel girder erection, reply beam check, distortion, defect overproof time, could install after process. Remove the greasy dirt on crane girder surface, silt, dust and other impurities, before lifting, tied up centre of gravity adjustment balance with wireline, and tied up at the both ends rope made of hemp, as pining down the adjustment direction slipping and restricting. After the front preparation work of lifting is ready, first carries out examination and hang, stop hanging when height of lift is 100 200, check rigging stability and crane stability. Through confirm errorless after crane can be commanded slowly to rise, when at the bottom of beam higher than bracket face 150～200, adjustment beam at the bottom of with bracket face two reference line reach accurate position, commander's crane decline is in place, girder steel is hung on vertical rear placement bracket face, crane girder is reinforced temporarily, reach secure side and can pluck hook. Steel beam lifting adopt monolithic lifting, before lifting on request prepare adjustment plate, bolt and draw cable rope at two ends. Should be connected with bolt in time after hoisted in position, and by beam between edge with post web plate be connected, align with water level gauge and band line, after meeting specification, bolt tightened, main lifting operation is: post, beam pack, stops an inspection, lifting, beam and support are installed, quality inspection, and steel ladder platform plate is installed.It is assembled that Steel Structure Installation adopts sheet frame ground to expand, the method that combined hanging and single Components installation combine, and installs secondary beam, connection beam, support afterwards, and stay according to the requirement of equipment hoisting and establish indivedual walking beam, fastening again after equipment is installed. Frame installation order is upper strata after first lower floor; First main structure, rear aggregated(particle) structure; The inside structure is first installed, the outer bilge construction of rear installation. The first primary member of the fastening order of component, rear secondary member. The fastening order of each beam on same framework is: first fastening upper node, more fastening bottom node, last fastening middle part node. The installation method adopting single-column single-beam is installed in screening tower workshop, it may also be useful to 2 25 tons are hung machine and coordinate installation. First steel post low for dedusting platform is filled during installation, pull on guy, and be linked to be entirety with crossbeam, then hoisting machine room main post, now uses two to hang machine and coordinates, an installation column, one crossbeam is installed, it is ensured that column installs rear frame member and also can connect immediately, makes to be linked to be between column entirety. Machine room inner funnel, end to end cylinder support, cylinder all should be placed in machine room with erection schedule end to end, otherwise subsequent installation is very difficult.
(2) sizing screen equipment hoisting: the installation order of vibratory screening apparatus is: basis checks, basis line, the lower chute of sieve is installed, vibratory screening apparatus bearing is installed, spring is connected with bearing, vibratory screening apparatus is in place in supporting, drive unit support and drive unit installation; Basis checks: check outside surface do not have crackle, hole, peel off and the phenomenon such as reinforcing bar is exposed; Check physical dimension and the position on basis; Check surface level; Check reserved bolt relative deviation; Basis line: with reference to drawing, marks the longitudinal cenlerline of vibratory screening apparatus to sieve tower column axis as benchmark; Mark the longitudinal and transverse medullary ray of vibratory screening apparatus bearing and drive unit support; Fundamentals of Measurement absolute altitude; The permissible variation that vibratory screening apparatus bearing is installed: levelness: 2/1000, checks with water level gauge; Diagonal lines deviation: 1/1000, checks with dipstick metering; Relative level is poor: 2mm, checks with spirit-leveling instrument; Holding spring support to install: should fully contacting with upper undersetting, spring should be contour, entering discharge end must not more than 5mm with the end contour deviation of spring, and each spring verticality is no more than the 25/1000 of spring height. The hoisted in position of vibratory screening apparatus: vibratory screening apparatus is in place, due to the volume of vibratory screening apparatus bigger and heavier, so the lifting of vibratory screening apparatus can according to on-site actual situations, first it is discharged at smooth good equipment after sizing screen equipment to goods and stacks field, steel construction hangs with 200T crane master after possessing lifting condition, and 50T crane coordinates transhipment with flat-bed trailer. 200T crane first time lifts 2 sizing screens in 2 positions, station, axis southern side, first fills 2,1-3 axle, and then 200T crane lifts 2 sizing screens in 4 positions, station, axis southern side two times. Scrape trigger segmentation 50T crane and winch to 3rd floors planes, the mode installation in position gathered mutually with thick stick and jack.
(3) installation of trigger is scraped: scrape trigger erecting equipment and mainly contain drive unit, head, tail and equipment box, after civil engineering completes, line setting by drawing, based on 5 tons of stable cars, in conjunction with 3 tons of chain blocks, all devices lifting is put in place, install according to drawing again, when medial launder is installed, install successively by the sequence number (SN) outside medial launder. When chain assembles, by vertical for chain link cup soldering opening upwards, flat boxing interface is to chain medullary ray. Upwards, plane is downward for shack boss. Scrape to be arranged on by flap type again after trigger installs and scrape above trigger outlet.
