Abstract
The utility model discloses an open shelves size adjustable winch drum body assembly, including the cell body, cell body and barrel fixed connection, cell body both ends apical grafting have a curb plate, have worn round coupling nut between the curb plate of every side, barrel convex shoulder, the brake disc, barrel convex shoulder position parallel arrangement at every coupling nut place has a pair of adjusting bolt, installs locknut on adjusting bolt, adjusting bolt and barrel threaded connection to adjusting bolt's inner and curb plate apical grafting. The utility model discloses the device can be according to wire rope's actual diameter and open a shelves size to the barrel assembly and adjust, guarantees wire rope marshalling in the barrel assembly, and compaction, indiscriminate, effectively solves the disorder cable problem of winch drum body assembly.
Description
Technical field
The utility model belongs to Petroleum Machinery Industry technical field, relates to a kind of drawworks drum assembly opening grade size adjustable.
Background technology
Winch is the core component of oil-well rig, cylinder disorder cable problem be always puzzlement winch normally work the most easily send out, the most generally, the most difficult chronic disease broken through.A large amount of practice shows, it is can effectively prevent cylinder disorder cable that suitable drawworks drum assembly opens a grade size, this is because: 1) barrel assembly opens the critical size that grade size is barrel assembly structure.When wirerope-winding is on barrel, barrel assembly opens the number of turns that grade size directly determines every layer of wirerope-winding.2) barrel assembly opens grade size is the critical size affecting wirerope-winding quality.For every layer of barrel assembly being wound around a fixing turn steel rope: it is bigger that barrel assembly opens grade size, and the steel rope width between centers being wrapped in barrel assembly is bigger than normal, between steel rope arrangement, there is gap, very easily occur riding rope, folder rope phenomenon; Barrel assembly opens a grade undersized, does not go, presses unreal, very easily occur rope skipping phenomenon under steel rope.3) what is more important, for the steel rope of given nominal dimension, the diameter of steel rope is not fixed value, always there is Mismachining tolerance, the wirerope diameter of different batches is often different, and the steel rope of same batch is often inconsistent at the diameter of different section, and barrel assembly to open a grade size be changeless, so often cause: certain a collection of wirerope-winding is no problem, and disorder cable occurs when changing another batch of steel rope; Disorder cable is there is not and at other layer, disorder cable occurs in the steel rope of same batch at certain one deck.4) most importantly, in rig and winch working process, constantly rub between steel rope, and rig hangs the continuous increase of drilling string load, wirerope diameter is made constantly to reduce like this, barrel assembly is opened grade size and also should be done respective change in theory, but on current winch, barrel assembly opens grade size and but can not change thereupon.
At present, after disorder cable appears in winch, often take polishing side plate to open grade size to increase or increase liner plate to reduce out these two kinds of ways of grade size, waste time and energy, inefficiency.
Utility model content
The purpose of this utility model is to provide a kind of drawworks drum assembly opening grade size adjustable, solves prior art after disorder cable appears in winch, takes polishing side plate to open grade size to increase or increase liner plate to reduce out a grade size, the problem wasted time and energy.
The technical scheme that the utility model adopts is, open a drawworks drum assembly for grade size adjustable, comprise cell body, cell body is fixedly connected with barrel, cell body two ends apical grafting has side plate, is installed with a circle coupling nut between the side plate of every side, barrel convex shoulder, brake disc;
Be arranged with a pair adjusting bolt in parallel in the barrel convex shoulder position at each coupling nut place, adjusting bolt is provided with black nut, and adjusting bolt is threaded with barrel, and the inner of adjusting bolt and side plate apical grafting.
The drawworks drum assembly opening grade size adjustable of the present utility model, is further characterized in that:
The inner beveled aperture being compressed side plate by taper face of coupling nut, the unthreaded hole that the outer end of coupling nut passes brake disc is provided with spring shim.
The beneficial effects of the utility model are, for the steel rope of different batches, different-diameter under same batch, can ensure that steel rope arrangement is overall, compress between steel rope, conscientiously; Or in oil-well rig drilling process, for the situation that steel rope in use constantly attenuates, in good time adjustment winch drum opens a grade size, ensure that steel rope arrangement is overall, compress between steel rope, conscientiously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model device;
Fig. 2 is the A place local structure schematic diagram in Fig. 1.
In figure, 1. barrel, 2. cell body, 3. side plate, 4. brake disc, 5. attaching screw, 6. coupling nut, 7. spring shim, 8. adjusting bolt, 9. black nut.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
With reference to Fig. 1, Fig. 2, the structure of the utility model device is, the structure of whole device is symmetrical mutually along barrel 1 axial line two ends, comprise cell body 2, cell body 2 is fixedly connected with barrel 1 (adopting plug welding mode), cell body 2 two ends apical grafting has side plate 3, a circle coupling nut 6 is installed with between the side plate 3 of every side, barrel 1 convex shoulder, brake disc 4, coupling nut 6 the inner compresses the beveled aperture of side plate 3 by taper face, the unthreaded hole that the outer end of coupling nut 6 passes brake disc 4 is provided with spring shim 7 and coupling nut 6, and spring shim 7 plays locking effect;
A pair adjusting bolt 8 is arranged with in parallel in the barrel 1 convex shoulder position at each coupling nut 6 place, adjusting bolt 8 is provided with black nut 9 and plays locking effect, adjusting bolt 8 is threaded with barrel 1, and the inner of adjusting bolt 8 and side plate 3 apical grafting.
The utility model device opens to barrel assembly the method that grade size adjusts, and implements (be described for A place, the left side local structure of this device, the right is similar) according to following steps:
If think that a grade size is opened in minimizing, unscrew coupling nut 6, twisted by attaching screw 5 and move right, now adjusting bolt 8 coordinates and twists and move right and hold out against side plate 3, treats that grade size of opening between two end side panels 3 arranges suitable, tightens black nut 9, coupling nut 6.
If think that a grade size is opened in increase, unscrew black nut 9, adjusting bolt 8 is twisted and is moved to the left, now tightening coupling nut 6 drives side plate 3 to move to left by attaching screw 5, treat that grade size of opening between two end side panels 3 arranges suitable, tighten coupling nut 6, black nut 9.
