Abstract

The utility model relates to a through shaft assembling/disassembling tool for a cooling bed lifting draw bar through shaft. The tool comprises a drawing head, a claw hammer, and a button pole, wherein one end of the drawing head is connected with the button pole, the claw hammer is arranged between the drawing head and the button pole, and a groove is formed in the middle of the outer side of the claw hammer. Compared with the prior art, the tool provided by the utility model has the following beneficial effects that: the through shaft assembling/disassembling tool for the cooling bed lifting draw bar through shaft has the characteristics of simple structure, reasonable design, convenient replacement, and strong practicability, effectively ensures the matching precision between the draw bar through shaft and a crank hole, reduces the difficulty in disassembling the draw bar through shaft and the labor intensity of a worker, improves the working reliability of a cooling bed lifting block in driving the draw bar through shaft, reduces the time for replacing the through shaft, simultaneously improves working efficiency and reduces the cost of an equipment spare part.

Description

A kind of cold bed lifter drawing bar is worn a dismantling device of wearing of axle

Technical field

The utility model relates to field of metallurgical machine, and particularly a kind of cold bed lifter drawing bar is worn a dismantling device of wearing of axle.

Background technique

Cold bed is one of visual plant of continuously hot rolling seamless steel pipe unit, the height of cold bed equipment availability directly influences steel pipe's production output, but it is very high that the critical component pull bar of this system is worn a rate of fault, when replacing is worn spool because compact equipment, the upkeep operation narrow space, crank throw is worn a serious wear, dismantle very difficult, cause the repair time long, need carry out destructive situation of removing happens occasionally, cause crank throw, wear axle, joint shaft bearing, the waste of spare parts such as rod head, the method of once taking a tolerance to strengthen is handled, though but made things convenient for through finding after actual use a period of time to change, the axis hole serious wear can not guarantee life cycle.Both wasted standby redundancy, cause overhaul efficiency low again, labor strength is big, therefore is necessary the cold shaft portion of wearing of wearing the elevator system is improved, and to the choose understanding of method of blind hole axle, study and survey and draw in conjunction with on-the-spot actual conditions and designed novel axle and the special-purpose dismantling device worn, use this cover instrument, not only can avoid choosing in the past and wear the axle difficulty, defectives such as efficient is low, and can also guarantee the spare part serviceability rate, reduce spare unit greatly, the loss of spare part.

Summary of the invention

The purpose of this utility model provide a kind of simple in structure, reasonable in design, guarantee to wear the dismantling device of wearing that axle can choose fast.

For achieving the above object, the utility model is realized by the following technical solutions:

A kind of cold bed lifter drawing bar is worn a dismantling device of wearing of axle, comprises the draw head, pulls out hammer and dead man, and the first end of described draw is connected with dead man, is provided with between draw head and the dead man and pulls out hammer.

The described outer middle side part of hammer that pulls out is provided with groove.

Compared with prior art, the beneficial effects of the utility model are:

A kind of cold bed lifter drawing bar is worn a dismantling device of wearing of axle, have characteristics simple in structure, reasonable in design, that replacing is convenient, practical, guaranteed that effectively pull bar wears axle and the quality of fit in crank throw hole, reduce pull bar and worn difficulty and the working strength of workers that axle is dismantled, improve cold bed elevator driving pull bar and worn a functional reliability, reduce the replacing time of wearing axle, also improved working efficiency simultaneously, reduced the equipment and spare part expense.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further specified:

As Fig. 1, Fig. 2 and shown in Figure 3, a kind of cold bed lifter drawing bar of the utility model is worn a dismantling device of wearing of axle, comprises draw head 2, pulls out hammer 3 and dead man 4, and described draw head 2 one ends are connected with dead man 4, be provided with between draw head 2 and the dead man 4 and pull out hammer 3, pull out hammer 3 outer middle side parts and be provided with groove 7.

As shown in Figure 4, wear a main body 1 one ends and be provided with two or more draw mouths 5, wear a main body 1 inside and be provided with hydraulic fluid port 6, when needs are worn axle when extracting with pull bar, at first an end of draw head 2 is connected with draw mouth 5 on wearing a main body 1, the pulling end faces that pull out hammer 3 bump dead mans 2 will be worn axle and extract continuously then.

Above described only be basic principle of the present utility model, be not that the utility model is imposed any restrictions, everyly according to the utility model it is carried out equivalent variations and modification, all within the category of the art of this patent protection scheme.

Claims
