The realization of the object of the invention, functional characteristics and advantage will in conjunction with the embodiments, are described further with reference to accompanying drawing.
Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Referring to figs. 1 through Fig. 3, in this preferred embodiment, a kind of four machines lift installation method, comprise the following steps:
Step S10, connects a secondary hanging beam 2 by below every two drivings 1 in four drivings 1, and connect a main hanging beam 3 below two secondary hanging beam 2, described main hanging beam 3 is provided with multiple suspension centre 4;
Step S20, according to treating that the weight of hanging device selects the suspension centre 4 on described main hanging beam 3, being connected by many steel ropes and treating the hanger on hanging device and the suspension centre 4 on main hanging beam 3;
Step S30, control four drivings 1 and hook up simultaneously, make to treat that hanging device slowly leaves ground, after being lifted into installation position, slow dropping place carries out the assembling of miscellaneous equipment again.
Particularly, secondary hanging beam 2 and driving 1 between and all adopt pinned connection between main hanging beam 3 and secondary hanging beam 2.When treating hanging device and unloading, first should reconnoitre and enter route, note installation site and the installation direction of equipment, guarantee in installation across being no longer shifted, turning to, to realize shortest distance lifting.
Further, with reference to Fig. 1, also comprised before step S10:
Four adjacent anticollision devices in driving 1 two ends are removed and draw close multiple described driving 1, connecting adjacent driving 1 with shaped steel by step S01, make four drivings 1 be linked to be an entirety.
Four drivings 1 are linked to be an entirety, thus ensure that the synchronism of four drivings 1.
Further, when control four driving 1 hooks up simultaneously, the same signal channel of remote controller furnishing of every two drivings 1 is operated two remote controllers with realization and controls four drivings 1.
The detailed process of lifting appliance is as follows:
(1) lifting of large of 30MN stretcher
1) adopt bearing pin to be connected to by suspender in driving 1, use the hanger on four steel rope connecting devices and the suspension centre 4 on main hanging beam 3.
2) control four that uses a teleswitch driving 1 hooks up simultaneously, makes equipment slowly leave ground, and when distance ground 200mm height, stop hoisting, four drivings 1 run simultaneously, and by equipment hoisting to installation position, slow dropping place, assembles with road wheel.
3) according to weight of equipment and the driving 1 hoisting capacity difference of each lifting, in hoisting process, different suspension centres 4 is selected.
4) diameter phi 75 steel rope that steel rope adopts 6 × 37 is lifted, 2 of long 2.8m, 2 of long 8.5m, 2 of long 6.5m.
5) head, tail frame carries out tensile beam lifting and other equipment hoistings, assembling after having lifted.
(2) lifting of large of 100MN stretcher
1) adopt bearing pin to be connected to by suspender in driving 1, use the hanger on four steel rope connecting devices and the suspension centre 4(on main hanging beam 3 as shown in Figure 2).
2) control four that uses a teleswitch driving 1 hooks up simultaneously, makes equipment slowly leave ground, and when distance ground 200mm height, stop hoisting, four drivings 1 run simultaneously, and by equipment hoisting to installation position, slow dropping place, assembles with stretcher road wheel.
3) different according to the weight of equipment of each lifting, and driving 1 hoisting capacity is different, selects different suspension centre 4(as shown in Figure 3 in hoisting process).The upper and lower of the stretcher headstock 5, stretcher tailstock 6 is measure-alike, and lifting mode is identical.
4) when the bottom lifting of the 100MN stretcher headstock 5, stretcher tailstock 6 puts in place, lift the dividing plate drawn high in beam and head, tail frame after assembling with road wheel, then lift the 100MN stretcher headstock 5, tailstock top.
5) diameter phi 80 steel rope 2 2.8m that steel rope adopts 6 × 37 are lifted, diameter phi 80 steel rope 2 3.2m of 6 × 37, diameter phi 80 steel rope 2 3.3m of 6 × 37.
6) head, tail frame carries out after having lifted drawing high beam lifting and other equipment hoistings, assembling.
Four machines that the present invention proposes lift installation method, adopt four machines to lift and can complete the lifting of many cover overweight equipments, the process of hoisting large-size equipment is simple and convenient, change techniques such as in the past adopting the lifting of large-tonnage wheel crane, hydraulic pressure lift lifting, there is easy to operate, that safety is high advantage, not only significantly can shorten installation period, reduce lifting cost simultaneously to a great extent and use.
These are only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure transformation utilizing specification sheets of the present invention and accompanying drawing content to do, or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
