Abstract
The invention relates to a power winch barrel spoke structure for a petroleum drilling machine. A power winch barrel device consists of a barrel body and a wheel hub; a circular center plate on the wheel hub adopts a topology optimized SIMP algorithm; and center plates at two ends of a barrel are similar to spokes in shape. The structure overcomes such defects in the prior art as material waste and cost increase caused by the strength of some parts far higher than the design requirement and reduction of the strength of the barrel caused by excessive removal of circular center plate materials or improper removal of parts. The circular center plate on the wheel hub adopts the topology optimized SIMP algorithm; under the precondition of satisfying the structural strength requirement, the structure is optimized, and the weight realizes reduction; and the structural size and shape of the spoke reach the matched shape and size with the change of the working conditions of the barrel, so that the device requires the fewest materials and has the highest in cost performance under the condition of satisfying working conditions.
Description
Technical field
The invention belongs to oil drilling and extracting equipment machinery manufacturing technology field, particularly to a kind of oil-well rig power
Winch drum spoke architecture.
Background technology
Winch, as the core of oil-well rig, has lifting drilling tool, send the functions such as brill.Cylinder is winch power train
The terminal of system, subjects the load that overhead traveling crane applies, so the performance of cylinder directly affects the fortune of hoisting system of rig
Line efficiency.
Before the present invention makes, barrel is made up of cylinder body and wheel hub, and the circular former on wheel hub is flat
Whole plate, its effect is to limit the axial displacement of steel wire rope and install brake gear.The minimum diameter of cylinder, cylinder
Shaft diameter and former thickness are the major parameters of roller frame design, generally use empirical equation to calculate.Especially
It is a complicated job, after obtaining former thickness, in addition it is also necessary to carry out stress for the determination of former thickness
Analyze, and the former according to said method designed, some partial intensities, far beyond design requirement, causes waste of material,
Cost increases.Part expert rule of thumb uses the method removing material to alleviate the weight of former, but to circular width
Plate material is removed too much or removal position is improper, and cylinder intensity all can be caused to reduce.
Summary of the invention
The purpose of the present invention is that and overcomes drawbacks described above, a kind of oil-well rig power winch cylinder spoke of design
Structure.
The technical scheme is that
A kind of oil-well rig power winch cylinder spoke architecture, power winch drum apparatus is by cylinder body and wheel
Hub forms, and the circular former that it is mainly characterized by wheel hub uses the SIMP algorithm of topological optimization, rolling
Cylinder two ends former be shaped like spoke-like.
The former physical dimension of described spoke-like and shape draw therewith along with the operation conditions change of cylinder
The size and shape joined.
Advantages of the present invention and effect are that oil-well rig power winch drum apparatus is by cylinder body and wheel hub
Composition.Circular former on wheel hub uses the SIMP algorithm of topological optimization, before meeting Structural strength calls
Put, its structure is optimized so that it is weight realizes lightweight.After SIMP algorithm optimization, cylinder
Two ends former be shaped like spoke-like, the physical dimension of spoke and shape are along with the change of the condition of work of cylinder
Draw the shape and size matched.By changing the planform of this cylinder two ends former, this device is made to exist
Under conditions of meeting operating mode, material requested is minimum, and cost performance is the highest.
Accompanying drawing explanation
Fig. 1 present configuration principle schematic.
In figure, each label represents that corresponding component names is as follows:
Wheel hub 1, cylinder body 2, spoke 3, steel wire rope 4.
Detailed description of the invention
As shown in Figure 1:
Winch drum is made up of the wheel hub 1 on cylinder body 2 and both sides, and casting respectively, by welding even
Being connected together, on wheel hub 1, the most circular former of spoke 3 utilizes Abaqus Topology Optimization Method to be optimized.
The application process of the present invention is described as follows:
During rig operation, when winch reaches to put forward the load limit, the power that cylinder is subject to is maximum fast line pull.At lower brill
During, fast line pull has moment of flexure, moment of torsion and the steel wire rope 4 that tightly wraps to barrel to the load that cylinder wall produces
External pressure.When transferring drill string and terminating brake, cylinder not only by the pulling force of drill string, is also stopped by dish
Big braking moment.According to above-mentioned cylinder force status, utilize the topological optimization of Abaqus, zero can be made after iteration
Piece volumes reduces, and reaches to optimize the purpose of cylinder.
This winch drum device, owing to have employed the cylinder after topological optimization, is meeting cylinder requirement of strength
On the premise of, the structure that only need to change former just can make the weight of this winch drum device be mitigated.This winch
Drum apparatus can reduce production cost, has higher market value and economy.
