Abstract
The invention relates to an auxiliary tool and a method for replacing a wire rope of a bridge crane. A gantry frame is manufactured on a cover plate on the upper part of a fixed pulley block of a drum of a bridge crane trolley; lifting rings are arranged on the two sides of the gantry frame; a chain hoist and a fixed pulley are arranged on the lifting rings on the two sides respectively; thus the old wire rope is replaced by a new one. Compared with the prior art, the auxiliary tool and the method have the advantages that: after the device is used, the time for replacing the wire rope is greatly shortened each time, the personal safety of construction personnel is guaranteed, the labor intensity of workers is relieved, the labor productivity is improved, and smooth running of workshop production is guaranteed.
Description
Technical field
The present invention relates to the accessory machinery field of tool, relate in particular to a kind of traverse crane more accessory appliances and the method for change steel rope.
Background technology
Crane in bridge type is that modern industry is produced indispensable equipment, be widely used in the operation such as lifting, transportation, loading and unloading, installation of various materials, alleviate physical labor intensity greatly, improved labor efficiency, finished the work that the people can't finish sometimes.Steel rope is as the spare part that directly bears weight, and its degree of wear has reached the standard of scrapping of steel rope, just should in time change, otherwise will produce the serious person and equipment breakdown.When the crane in bridge type steel cable is changed at present, what in most cases adopt is that chaining hangs and fixed pulley on the monorail crane of factory building girder, finish the replacing of dismounting, installation and the new and old rope of forehead, because this upkeep operation one is to be subjected to environmental constraints: the stop position of hoisting crane must be that two winding drum is aligned monorail crane and main house beam below, and manufacturing line is stopped production; The 2nd, need to creep on 40 meters high of frame workers' the factory building girder on distance ground, will overhaul with chain hoist and fixed pulley and hang on the girder, cause work efficiency low, dangerous big, although take safety measures, also be difficult to guarantee workmen's personal safety.
Summary of the invention
Purpose of the present invention provides a kind of lifting tonnage in the traverse crane more than hundred tons more accessory appliances and the method for change steel rope, and is easy and safe to operate, increases work efficiency.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of traverse crane is the accessory appliances of change steel rope more, it is characterized in that, makes a door type frame on the cover plate of the fixed pulley group top of OTC's trolley reel, and the door type frame both sides are provided with suspension ring; On the suspension ring of both sides, be respectively equipped with chain hoist and fixed pulley.
The traverse crane of the described accessory appliances of employing claim 1 is the method for change steel rope more, it is characterized in that this method comprises the steps
1) with chain hoist the forehead of old steel cable is pinned and mention, remove the connecting link pin of forehead and equalizing bar, this end that makes old steel cable is a free end;
2) the dismantle forehead of old steel cable is with the fag end of new steel cable and the fag end solder together of old steel cable;
3) reel forward scrolling is brought new steel cable into the fixed pulley group with old steel cable, after with several circles of new steel cable winding reel, new steel cable and old steel cable weld is cut off, and with clamp new steel cable fag end is locked on the OTC's trolley car body;
4) the reverse scrolling of reel puts down old steel cable and fag end is untied from reel;
5) new steel cable fag end is fixed on the reel;
6) scrolling reel on reel, is put new steel cable to movable pulley with the new steel cable of the other end and to be cut off after equalizing bar length, loads onto forehead at new steel cable fag end, mentions to the equalizing bar place;
7) with chain hoist forehead is pinned, the connecting link pin of forehead and equalizing bar is installed.
Compared with prior art, the invention has the beneficial effects as follows: after utilizing this device, shortened the time of each replacing steel cable greatly, workmen's personal safety is guaranteed, alleviate worker's labour intensity, raised labour productivity, guaranteed the direct motion of Workshop Production.
Description of drawings
Fig. 1 is the more scheme drawing of change steel rope of traverse crane.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:
A kind of traverse crane is the accessory appliances and the method for change steel rope more, comprises the steps
1) make a door type frame 1 on the fixed pulley group 12 top cover plates 3 of OTC's trolley reel 11, door type frame 1 both sides respectively are provided with two suspension ring 2;
2) chain hoist 4 and fixed pulley 5 are hung on the suspension ring 2;
2) with chain hoist 4 forehead 6 of old steel cable is pinned and mention, remove the connecting link pin 8 of forehead 6 and equalizing bar 7; This step is that the side fag end with old steel cable becomes free end;
3) coir rope 9 one ends are connected with forehead 6, and the other end is walked around fixed pulley 5 and hung down to ground, and the ground staff slowly loosens coir rope 9, and forehead 6 and old steel cable 10 are fallen to the ground, and writes down the number of turns of old steel cable on the reel 11 this moment;
4) the dismantle forehead 6 of old steel cable is with the fag end of new steel cable 10 and the fag end solder together of old steel cable;
5) reel 11 forward scrollings are brought new steel cable 10 into fixed pulley group 12 after with 11 liang of circles of new steel cable 10 winding reels with old steel cable, and new steel cable 10 and old steel cable weld are cut off, and with clamp new steel cable fag end are locked on the OTC's trolley car body;
6) reel 11 reverse scrollings put down old steel cable and fag end is untied from reel;
7) new steel cable 10 fag ends are fixed on the reel 11;
8) the scrolling reel 11, with new steel cable 10 on the reel set by step 3) remember the number of turns, the new steel cable of the other end is put to movable pulley to equalizing bar is cut off after 7 length, load onto 6 of volumes at new steel cable 11 fag ends, mention to equalizing bar 7 places with coir rope 9;
9) with chain hoist 4 forehead 6 is pinned, the connecting link pin 8 of forehead 6 and equalizing bar 7 is installed.
The application of this device has solved that the hoisting crane stop position was limited in the past, cause manufacturing line to stop production, when workmen's chain type hoisting crane and fixed pulley, a difficult problem of creeping on the factory building girder that need are 40 meters high on distance ground has guaranteed worker's personal safety, reduce labour intensity, raise labour productivity, chassis maintenance or repairing are changed steel cable simultaneously, and another hoisting crane normally moves, the assurance continuous casting line is produced, for the production direct motion provides condition.
