Description
Technical field
The present invention relates to a kind of methods for replacing metallurgical bridge crane wirerope, belong to lifting equipment maintaining method
Technical field.
Background technique
In iron and steel enterprise, metallurgical bridge crane carries the transport of molten iron and molten steel, and work frequent and environment
Temperature is high.Metallurgy uses two-fold cylinder, double flat balance beam and four wirerope, process of the wirerope in handling molten steel with bridge crane
In play an important role.Since wirerope is three big important components (brake, wirerope and suspension hook) of overhead traveling crane safety in production
One of, using frequent, wear more, it is therefore desirable to often be replaced, to guarantee to keep the safety in production, avoid the generation of accident.
Currently, there is the following aspects in metallurgical bridge crane more change steel rope:
First, metallurgical bridge crane shares four, wirerope, and the length of every wirerope is about 300 meters.Changing rope every time
Before new rope is put well need in advance, four 300 meters of steel wire rope releasing is the very big work of workload, need a large amount of manpower,
It is also required to occupy very big place.
Second, the connection of new old wire rope is problematic, in the past by new and old rope end directly with welding together, in raising
Connecting portion is harder in the process, the bending of wirerope easily occurs, turns round strength phenomenon.
One end of third, the installation of wedge joint, the rope end of four wirerope is fixed with wedge joint, in the past connects wedge shape
Head, which unloads, places ground, is successively pulled with 5 tons of guide chains and accomplishes fluently connector, time-consuming and laborious.
Problem existing for metallurgical bridge crane more change steel rope is efficiently solved at present, to production
Detrimental effect is gone on smoothly, it would be highly desirable to be improved.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of methods for replacing metallurgical bridge crane wirerope.It is this
Method can reduce the place that wirerope occupies in replacement process, and the discounting, bending after being effectively prevented from wirerope connection are existing
As shortening replacing construction, mitigating the labor intensity of worker.
The technical solution for solving above-mentioned technical problem is:
A method of replacement metallurgical bridge crane wirerope, it is carried out using following steps:
A. new wirerope is placed on rope support, four rope supports for placing new wirerope are placed individually into below overhead traveling crane；
B. suspension hook is fallen, it is it is steady, be securely placed on ground, make pulley vertically upward；
C. the old wire rope lower end respectively by two wedge joints connection on two equalizer bars is successively cut off, and reserves rope end, together
When overhead traveling crane main carriage on staff connector rope clamp is dismantled, the drift of the wedge joint on aerial equalizer bar is removed；
D. with the rope end of the new old wire rope of nut-welding, the nut of new old wire rope is connected by rope clamp；
E. lifting mechanism is started, new wirerope is driven with old wire rope, old wire rope is rolled on reel, when new wire rope roll arrives
Reel 3 stops when enclosing, and unclamps rope clamp, new wirerope is temporarily tied up on the suitable position of trolley, is then driven old wire rope
Rope end is dropped down into ground by the hole under equalizer bar；
F. it by rope end that four old wire ropes are fallen and after being fixed respectively with the other end of four new wirerope with rope clamp, then opens
Four new wirerope are mounted respectively to wedge when the other end of four new wirerope rises to equalizer bar position by dynamic lifting mechanism
In shape connector, each connector rope clamp is successively accomplished fluently, after the rope end of four new wirerope is installed to four wedge joints, then
Slow raising is accomplished fluently four wedge joints of equalizer bar using the gravity of wirerope；
G. two reels are rotated further by, four old wire ropes are dropped down into ground respectively, have all been fallen to old wire rope, by old wire rope
Pressing plate dismantle, old wire rope all unloads, then successively uses be fixed temporarily four new wirerope on two reels respectively
Pressing plate presses, and the both ends of four new wirerope all fix；
H. lifting mechanism is started, reel winds new wirerope, and raising suspension hook, all more change jobs end.
The method of above-mentioned replacement metallurgical bridge crane wirerope, the rope support of the new wirerope of placement in the step a by
Bracket and wirerope cheese composition, bracket are welded by channel steel and I-steel, and bracket is fixed on two opposite bearings
Seat, rotation axis are mounted between two bearing blocks, and wirerope cheese covers on the rotating shaft, the length of the wirerope of wirerope cheese
For the length needed to change.
The method of above-mentioned replacement metallurgical bridge crane wirerope, in the step d, the spiral shell of new old wire rope both ends welding
Parent phase pair is each passed through new old wire rope both ends nut using wirerope lantern ring, and the both ends of wirerope lantern ring are connected solid by rope clamp
It is fixed.
The beneficial effects of the present invention are:
The present invention places new wirerope using rotatable wirerope cheese, and occupied ground when avoiding new steel wire rope releasing is adopted
The time is saved with scale rope, and alleviates the labor intensity of worker；Steel wire is used after the rope end welded nut of new old wire rope
Rope sling is connected with rope clamp, is realized new old wire rope and is directly flexible coupling, and the torsion strength in old wire rope will not pass to new wirerope
On, it ensure that the use of new wirerope, and avoid and be obstructed when passing through pulley；Wedge joint on equalizer bar penetrates new steel
After cord, wedge joint is accomplished fluently using the gravity of wirerope, the time is greatly saved in this way, alleviates labor intensity.
The present invention is to replace initiating for metallurgical bridge crane wirerope method, operatively solves wirerope and is replacing
In the process the problem of the discounting after occupied ground, wirerope connection, bending, replacing construction is significantly shortened, rope technique is put and saves
10 people 6 hours, the installation of wedge joint saved 8 people 4 hours, and alleviate the labor intensity of worker.The present invention realizes
Metallurgical bridge crane wirerope changes the optimization of rope technique, optimizes the connection type of new and old steel wire rope, extends wirerope
Service life.
