Abstract
The invention discloses a floating crane revolving support dismounting method, which comprises the following steps of: firstly making a preparation before dismounting, then dismounting cables and connecting pipes inside a cylinder; dismounting an inclined ladder, a roller and a roller support, establishing a slide rail platform, establishing a process platform and a slide rail on the fixed cylinder, lifting up and moving out the revolving support, dragging the revolving support on the slide rail, moving to the outer side, hoisting to the ground, hoisting a new revolving support onto the slide rail, dragging to an installation position, and installing. The dismounting method provided by the invention is convenient to operate, is safe and reliable, and is used to save labor and time.
Description
Technical field
The present invention relates to a kind of floating crane revolving support dismounting method.
Background technology
At present, the maintenance method is supported in revolution for crane barge, with top rotating part complete removal, then revolution is supported and maintained, because the weight of rotating part all parts is large, the dismounting slinger makes comparisons heavy, the not only waste of manpower of this kind method, financial resources, material resources, and also the lifting meeting causes certain distortion to member.
Summary of the invention
The objective of the invention is provides a kind of easy to operate, time saving and energy saving, safe and reliable floating crane revolving support dismounting method in order to overcome above deficiency.
Purpose of the present invention is achieved through the following technical solutions: a kind of floating crane revolving support dismounting method, may further comprise the steps: at first carry out the preparation before removing: jib is placed on the jib shelf, to turn round anchor and put down, the anti-piece of carving that inclines between structure and the revolution support lower railway in front portion will be carved tightly; Then remove cylinder inner cable, connection pipe: will draw the cable that is installed on the centre collector ring from reversing chassis and remove, and from cylinder revolution bracing frame, all move in the reversing chassis center crossbeam cable fag end fixing, then with asbeston etc. with the protection of cable parcel, prevent damage in the construction; Connection pipe in the centre collector ring is pulled down, first connection pipe and reversing chassis junction are cut open during dismounting, must not injure the reversing chassis mother metal when cutting open, after cutting open connection pipe and plunging joint tie bolt are removed, then connection pipe is placed on the centre collector ring support and fixes, with protective cloth with centre collector ring parcel protection (as shown in Figure 1); Remove inclined ladder, roller and rolling wheel support, roller and rolling wheel support are positioned on lower railway corresponding to reversing chassis front and back support rail beam gap, then winching to the appointed place also notes protecting, support replacing complete rear whole recoveries (as shown in Figure 2) until revolution, inclined ladder is removed, and supports until revolution and changes complete rear recovery (as shown in Figure 3); Build the slide rail platform, build technique platform and slide rail (as shown in Figure 4) at the fixed part cylinder; To turn round and support jacking, shift out: remove the bolt (as shown in Figure 5) that is connected between the bolt that is connected between oil groove on the revolution bracing frame, outside race bearing and the reversing chassis, revolution bracing frame and the turntable, after disassembling bolts between outside race bearing and the center shaft connecting panel is complete, with jack the outside race bearing is ejected (as shown in Figure 6) from the center shaft connecting panel; Old revolution support is drawn on the slide rail, moves on to the outside, then be lifted into ground (as shown in Figure 7); To newly turn round support and be lifted on the slide rail, be drawn to the installation site, be in place (as shown in Figure 8).
The present invention compared with prior art has the following advantages:
By the method floating crane revolving support is removed, greatly saved human and material resources, financial resources, and saved the valuable time.

The specific embodiment:
In order to deepen the understanding of the present invention, the invention will be further described below in conjunction with embodiment, and this embodiment only is used for explaining the present invention, does not consist of the restriction to protection domain of the present invention.
A kind of specific embodiment of unit assembling method of large-size gantry crane of the present invention may further comprise the steps:
Preparation before at first removing is placed into jib on the jib shelf, will turn round anchor and put down, and the anti-piece of carving that inclines between structure and the revolution support lower railway in front portion is carved tightly; Remove again cylinder inner cable, connection pipe 1 etc., to draw the cable that is installed on the centre collector ring 2 from reversing chassis removes, and from cylinder revolution bracing frame, all move in the reversing chassis center crossbeam cable fag end fixing, then with asbeston etc. with the protection of cable parcel, prevent damage in the construction; Connection pipe 1 in the centre collector ring 2 is pulled down, first connection pipe and reversing chassis junction are cut open during dismounting, must not injure the reversing chassis mother metal when cutting open; After cutting open connection pipe and plunging joint tie bolt are removed; Then connection pipe is placed on the centre collector ring support and fixes; With protective cloth the centre collector ring parcel is protected; Remove again inclined ladder, roller and rolling wheel support, remove roller and rolling wheel support on lower railway corresponding to reversing chassis front and back support rail beam gap, then winch to the appointed place and also note protecting, support the complete rear whole recoveries of replacing until revolution; Inclined ladder is removed, and supports until revolution and changes complete rear recovery; Build slide rail platform 3, build technique platform and slide rail at the fixed part cylinder; To turn round and support jacking, shift out: remove first the bolt that is connected between the bolt that is connected between oil groove on the revolution bracing frame, outside race bearing and the reversing chassis, revolution bracing frame and the turntable; After disassembling bolts between outside race bearing and the center shaft connecting panel is complete, with jack the outside race bearing is ejected from the center shaft connecting panel; Again old revolution is supported 4 and be drawn on the slide rail, move on to the outside, then be lifted into ground; To newly turn round support 5 and be lifted on the slide rail, be drawn to the installation site, be in place.
Use this method to carry out floating crane revolving support and not only saved a large amount of human and material resources, financial resources, and avoided the distortion of member.
