Abstract

A method for installing the gantry crane features that in the procedure of lifting up the large steel beam, the rigid legs and flexible legs are also lifting. It includes such steps as in-situ assembling master steel beam, hanging the carrier and maintenance hoist from the master beam, standing up two lifting towers, hydraulic lifting while segmenting assembling rigid legs and flexible legs, installing the running mechanism to the legs, and structural installation.

Description

The installation method of transfer crane
Technical field
The present invention relates to a kind of installation method of transfer crane.
Background technology
Transfer crane is mainly used in the shipbuilding industry, and its installation method also is various at present.General method is earlier whole rigidity leg to be erect, and crossbeam is promoted to put in place again, so the center of gravity of this method rigidity leg when crossbeam is installed is difficult to adjust poor stability; The Important Project accident took place in so-and-so factory in the past, with its method for improving very big relation was arranged.
Summary of the invention
The object of the present invention is to provide a kind of new installation method, improve safety, agility and the reliability of transfer crane installation process.
For reaching above-mentioned purpose, the present invention uses two pairs " door " font pylon for promoting pylon, and the steel structure crossbeam is made at installation on ground, and segmentation of rigidity leg and flexible leg are hinged on the crossbeam.In the process of integrally hoisting steel structure crossbeam, rigidity leg and flexible leg put in place along with the lifting of crossbeam promotes together, realize whole transfer crane once-forming, safety, quick, reliable.
Preceence of the present invention is: the first, use the two secondary pylons that promote, and the guy adjustment reduces, and is safe and reliable; The second, rigidity leg and flexible leg are in place gradually along with the lifting of crossbeam, have reduced the work capacity of independent installation rigidity leg and flexible leg; The 3rd, use elevating ram stretch-draw pylon guy, guy is stressed accurately, and is easy to adjust.
Description of drawings
Fig. 1 arranges for the transfer crane elevator system.
Fig. 2 is a rigidity leg erection plan.
Fig. 3 is flexible leg erection plan.
The specific embodiment
In conjunction with the accompanying drawings the present invention is further described.See also shown in Fig. 1,2,3, the present invention is made up of crossbeam 1, rigidity leg 2, hinge JX 3, slide block 4, hinge JS 5, elevating ram 6, cat head gantry beam 7, pylon 8, traveling gear 9, A prefix 10, hinge JB 11, hinge JA 12, flexible leg cross sill 13, flexible leg 14 and slippage dolly 15 etc.
Installation method:
One, the installation of pylon and cat head gantry beam
The present invention uses two secondary tower framves 8 for promoting pylon, and the usable height of pylon 8 generally can be up to more than 100 meters according to the difference of concrete transfer crane and different, 4 meters in section, steel pipe cancelled structure, pylon 8 bottoms and basis, ground use bolted connection.Cat head gantry beam 7 is a box-structure.The load capacity of every pair of pylon reaches more than 2,000 ton.2 tower center distances across transfer crane crossbeam 1 are tens meters, and the cat head gantry beam that is provided with box-structure at the top of two pylons promptly promotes crossbeam, and elevating ram 6 is placed on cat head gantry beam 7, sees shown in Figure 2.After pylon 8 and beam 7 installations of cat head gantry, use the squareness of theodolite calibration pylon, after meeting the demands, they are fixed, and use chuck that the head-clamp alive of cable wind rope is tight with cable wind rope.
Two, the lifting of crossbeam
After cat head gantry beam 7 installations of pylon 8, the lifting of beginning crossbeam 1.Promote for the 1st time, hoisting depth is decided according to specific circumstances, stops when being approximately ten meters left and right sides, loads onto rigidity leg 2 topsides and flexible leg A prefix 10, calibrates its level attitude, and is fixed.Before promoting for the 2nd time, use hinge JS 5 that rigidity leg 2 one ends are linked on the crossbeam 1, the other end of rigidity leg 2 then is placed on 2 slippage dollies 15.Like this, rigidity leg 2 just promotes autofitting with crossbeam 1.After in place, calibrate axis, connect with electric welding.Simultaneously, before the 2nd lifting, use hinge JA 12 to link on the A prefix 10 flexible leg 14, crossbeam 1 puts in place like this, flexible leg 14 autofittings.
Three, Fig. 2 is seen in the installation of rigidity leg.The first step, the desired location is placed in 2 segmentations of rigidity leg, uses hydraulic jack to adjust the two ends upper-lower position, connects hinge JS 5 and hinge JX 3.In second step, one section of rigidity leg 2 segmentation promote with crossbeam rises, and the other end then uses the winch traction, to overcome horizontal friction force.The 3rd the step, with the traveling gear 9 that has assembled slowly push rigidity leg 2 below.At last, crossbeam 1 descends, with the calibration of segmentation place interface, welding.
Four, Fig. 3 is seen in the installation of flexible leg.After gantry hanging beam 1 promoted for the first time, the hinge JA 12 of symmetry was established in the both sides, A prefix 10 lower end of flexible leg, each one of both sides.The first step, flexible leg 14 keeps flat, and leg Guan Yiduan links to each other with A prefix 10 with hinge JA 12, and the other end links to each other with traveling gear with hinge JB 11.In second step, crossbeam 1 promotes, and flexible leg 14 follows naturally, on the horizontal direction of flexible leg walking mechanism, applies a horizontal drag force, can reduce vertical-lift power.In the 3rd step, crossbeam 1 puts in place, and flexible leg 14 incision positions close up naturally.
Because rigidity leg of the present invention is that segmentation progressively promotes, so well solved the problem of crank, add and use elevating ram stretch-draw pylon guy, can adjust and measure the stressed problem of guy accurately.The present invention has obtained very big success through test in the application of the whole lifting of two 600 tons * 182 meters gauntry cranes engineering.Therefore, this method has the characteristics and the significant advance of essence.
