Description

Method for dismounting is supported in the crane barge revolution

Technical field:

The present invention relates to a kind of crane barge revolution and support method for dismounting.

Background technology:

At present; The maintenance method is supported in revolution for crane barge, is with top rotating part complete removal, revolution is supported maintained then; Because the weight of each parts of rotating part is big; 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 deformation to member.

Summary of the invention:

The objective of the invention is in order to overcome above deficiency, provide a kind of easy to operate, time saving and energy saving, safe and reliable crane barge revolution to support method for dismounting.

The object of the invention is realized by the following technical programs: method for dismounting is supported in a kind of crane barge revolution; 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; Remove cylinder inner cable, tube connector then: 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 crossbeam of reversing chassis center the cable fag end fixing; Then with flameproof fabric etc. with the protection of cable parcel, prevent damage in the construction; Tube connector in the centre collector ring is pulled down; Earlier tube connector and reversing chassis junction are severed during dismounting; Must not injure the reversing chassis mother metal when severing; After severing tube connector and shaft coupling connecting bolt are removed, then tube connector are placed on the centre collector ring support and fix, with protective cloth with centre collector ring parcel protection (as shown in Figure 1); Remove inclined ladder, roller and rolling wheel support: remove roller and rolling wheel support on the corresponding lower railway of reversing chassis front and back support rail beam gap; Winching to the appointed place then also notes protecting; Treat all to restore (as shown in Figure 2) after revolution support replacing finishes; Inclined ladder is removed, and treats to restore (as shown in Figure 3) after revolution support replacing finishes; Build the slide rail platform, on the standing part cylinder, build technique platform and slide rail (as shown in Figure 4); To turn round and support jacking, shift out: remove the bolt that is connected between the bolt (as shown in Figure 5) that is connected between oil groove on the revolution bracing frame, bearing outer ring bearing and the reversing chassis, revolution bracing frame and the turntable; After disassembling bolts between bearing outer ring bearing and the central shaft connecting plate finishes, the bearing outer ring bearing is ejected (as shown in Figure 6) from the central shaft connecting plate with jack; Old revolution supporting traction to slide rail, is moved on to the outside, lift ground (as shown in Figure 7) then; New revolution support is 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:

Through the method crane barge revolution support is removed, practiced thrift human and material resources, financial resources greatly, and saved valuable time.

Label among the figure: 1-connection pipe, 2-centre collector ring, 3-slide rail platform, the old revolution of 4-are supported, 5-newly turns round support.

The specific embodiment:

In order to deepen to understanding of the present invention, will combine embodiment that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification 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 cylinder inner cable, connection pipe 1 etc. again; To draw from reversing chassis and be installed on the centre collector ring 2 cable and remove; And from cylinder revolution bracing frame, all move the cable fag end to reversing chassis center crossbeam internal fixation; 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, earlier connection pipe and reversing chassis junction are severed during dismounting, must not injure the reversing chassis mother metal when severing; After severing connection pipe and plunging joint tie bolt are removed; Be placed into connection pipe on the centre collector ring support then and fix; With protective cloth the centre collector ring parcel is protected; Remove inclined ladder, roller and rolling wheel support again, roller and rolling wheel support before and after the dismounting reversing chassis on the cooresponding lower railway of support rail beam gap winch to the appointed place then and attention protects, and wait to turn round support and change the whole recoveries in the back that finishes; Inclined ladder is removed, and treats to restore after revolution support replacing finishes; Build slide rail platform 3, on the fixed part cylinder, build technique platform and slide rail; To turn round and support jacking, shift out: remove bonded assembly bolt between oil groove, outside race bearing and the reversing chassis on the revolution bracing frame earlier, turn round bonded assembly bolt between bracing frame and the turntable; After disassembling bolts between outside race bearing and the center shaft connecting panel finishes, the outside race bearing is ejected from the center shaft connecting panel with jack; Again old revolution is supported 4 and be drawn on the slide rail, move on to the outside, lift ground then; New revolution is supported 5 lift on the slide rail, be drawn to the installation site, be in place.

Use this method to carry out the crane barge pivoting support and not only practiced thrift great amount of manpower and material resources, financial resources, and avoided deformation of members.
