Abstract

The utility model relates to a lifting device, particularly to a multifunctional and L-shaped lifting device for repair and installation, which mainly solves the technical problem in the prior art that the big labor intensity and the unsafety are caused because only a hoister can be utilized to be lifted if a traveling crane can not be lifted when the device is repaired. The utility model has the technical scheme that the utility model is in an L-shaped steel frame construction, a universal lifting head is installed at the end of a short arm of the L-shaped lifting device, and a special-purpose fixing device is fixed on the universal lifting head; the ratio of the short arm to a long arm is 1/ 2 to 1/3, the tail end of the long arm is provided with a balancing weight, and a plurality of lifting rings are arranged on the long arm. The utility model is suitable for a plurality of situations in which the traveling cranes can not be directly lifted, such as cold-rolling mills, hot-rolling mills, etc. In addition, the utility model can be disassembled and assembled once.

Description

Multi-functional L type maintenance of equipment hanging apparatus

Technical field: the utility model relates to a kind of hanging apparatus, particularly a kind of multi-functional L type maintenance of equipment hanging apparatus.

Background technology: also more and more higher along with the raising day by day of steel industry degree of automation to the requirement of the maintenance of equipment, accelerate inspection speed as far as possible, reduce the on-bne repair time, be the target that service work is pursued.In present service work, particularly when some important complex apparatus of maintenance, handling mounting or dismounting equipment needs a large amount of time, especially the occasion that can't directly lift by crane in many drivings, usually adopt a plurality of chain blocks to carry out handling, labour intensity is big, also has very big potential safety hazard.For example change the frame main shaft is overhauled the workman and is thought the most time-consuming thing of having a headache most at every turn, a main shaft needs four crane mans and other auxilian help at least, because travelling crane hook can't directly vertically lift by crane, have to adopt a plurality of cucurbits, draw as hanging of nonstandard place such as pipe-line equipment and tracheae fraisings in place, many places in frame, there are a lot of potential safety hazards and damage equipment, the steel rope that is suspended on the crane rubs very dangerous on the fast mouth of the backplate of frame always, also must pull out the connection backstop of transmission shaft could piecemeal transmission shaft to be lent, change needs 6 people and worked 8 hours.

Summary of the invention: the purpose of this utility model provides a kind of multi-functional L type maintenance of equipment hanging apparatus, solves low, the technical problem of poor safety of present hanging apparatus overhaul efficiency.Its technical solution is: a kind of multi-functional L type maintenance of equipment hanging apparatus, be L shaped steel shelf structure, and an omnipotent head that hangs is installed in the galianconism end of L type device, omnipotent hanging is fixed with special fixing device on the head.Galianconism and long-armed ratio are 1: 2～1: 3, at long-armed afterbody clump weight are arranged, and are provided with a plurality of suspension ring on long-armed.The beneficial effects of the utility model are: owing to adopted the hanging device of L type, make hang head can be than being easier near hanging the equipment of tearing open, according to lever principle, long-armedly played equilibrium activity, making hanging of equipment tear open can steadily carry out.Adopt this device to compare to improve work efficiency several times even tens of times with traditional dismounting handling, and convenient and swift, safe and reliable.

Description of drawings:

Fig. 1 is the utility model structural representation

Fig. 2 the utility model embodiment 1 special fixing device left view

Fig. 3 is the utility model embodiment 3 lifting scheme drawings

Among the figure: the 1-galianconism, 2-is long-armed, the omnipotent head that hangs of 3-, 4-suspension ring, 5-special fixing device, 6-clump weight.

The specific embodiment:

Embodiment 1, with reference to accompanying drawing 1,2, described L shaped steel shelf structure is that to cut into L type thickness by three be 2.5cm, and width is 22cm, and length is that the steel plate of 550cm is connected with riveted and fixed through full weldering, its interior face down bonding a slice band steel sheet in order to strengthen its tensile strength, galianconism 1 and long-armed 2 ratios are 1: 2, are fixed with clump weight at long-armed afterbody, and the profile of special fixing device 5 is prepared according to hanging device.When changing the frame main shaft, special fixing device 5 is a U type anchor fitting, and its closed end has an adapter plate to be fixed by bolts to omnipotent hanging on 3, be provided with fixed orifice at open end, during the dismounting main shaft, spindle nose is snapped in anchor fitting, fix in the fixed orifice inserting bolt.The hoist cable of driving is fixed in the suspension ring 4, can hangs and tear open.Faster 5 times than the time of utilizing the cucurbit dismounting originally, greatly improved overhaul efficiency, safety also is greatly improved.

Embodiment 2, with reference to Fig. 1, Fig. 3, hanging of quadrant torn open, when carrying out the dismounting of reeler quadrant at ordinary times, because the suspension hook of driving can't hang the inside, only hang the pickpocket and draw cucurbit batching the top, traditional way is to be hung with chain block bit by bit toward lira by driving earlier again, also there are many potential safety hazards in time-consuming like this effort again, and adopting traditional Hoisting Program to change four quadrants originally needs 4 lifting works of 3 pincers worker 12 hours.Use the utility model device, galianconism 1 and long-armed 2 ratios are 1: 2.5, omnipotent hang be fixed with on 3 one with long-armed parallel mechanical arm special fixing device 5, the bottom surface of mechanical arm is provided with two set collars, quadrant is fixed on just can conveniently hang on the mechanical arm by hoist cable tears open, only need 1 lifting of 2 pincers worker task of just in 4 hours, just can finishing the work with this device now, can improve work efficiency more than 7 times, and guaranteed safety, can well reach the maintenance requirement of high quality and high efficiency.All the other are identical with embodiment 1.

Embodiment 3, and with reference to Fig. 1, Fig. 3 tears open hanging of roller-way, when adopting the lifting roller-way of traditional scheme, be by several chain blocks and driving, and under the help of 4 crane mans, piecemeal pulling outward, pincers worker just can be finished the task of maintenance, and is very painstaking.Adopt the utility model, galianconism 1 and long-armed 2 ratios are 1: 3, only need the cooperation of the crane man task of just can finishing the work down, improve work efficiency more than 10 times, and are very laborsaving, conveniently, and safety.All the other are identical with embodiment 2.
