Description
Technical Field
The utility model relates to a rig plays to rise big rope and detects technical field, concretely relates to rig plays to rise big rope detection device.
Background
The large hoisting rope of the drilling machine is used for hoisting the derrick before the drilling operation starts and lowering the derrick after the drilling operation is finished, and the diameter of the conventional large hoisting rope is between 60mm and 80mm, and the length of the conventional large hoisting rope is generally hundreds of meters. Along with the increasing depth of domestic drilling, the corresponding drilling machine capability is also increased, the drilling machine for drilling the ultra-deep well with the drilling depth of more than ten thousand meters is the current development trend, the diameter of the corresponding lifting rope also needs to be thickened, and the lifting rope with the diameter larger than 80mm is applied more and more. The hoisting rope has a severe use environment, is easy to be collided and rubbed in the transportation and use process, is limited by field operation conditions, and is difficult to carry out scientific maintenance on the hoisting rope. Once the hoisting rope is broken in the operation process, the derrick is directly collapsed, and huge property loss and casualties are caused. In order to ensure the safe and stable lifting and laying down of the drilling machine, the lifting rope is required to have reliable performance. Generally, before the derrick is lifted, a magnetic flux leakage detection means is adopted to troubleshoot the lifting large rope, and the steel wire rope with the defect exceeding the standard is replaced in time.
For steel wire ropes for elevators, wharfs and bridges in other fields in China, the diameter of the steel wire ropes is generally small and generally does not exceed 50mm, and because the steel wire ropes are long, working parts are fixed and unified, the detection requirement is large, the detection technology is mature, and the detection efficiency and the detection accuracy are high.
The large hoisting rope has the advantages of large diameter, incapability of being moved by manpower, short length, frequent disassembly and assembly, no large detection requirement of steel wire ropes for elevators, wharfs and bridges in market demands, and no reasonable detection means at present. There are four common detection methods:
firstly, a detection instrument is fixed, a hoisting rope is slowly hoisted by a crane, or a motor vehicle is adopted to slowly drag the hoisting rope, so that the hoisting rope passes through the detection instrument. The defect is that the speed and the speed uniformity can not be controlled, and the detection precision is influenced. When the defect signal needs to be rechecked in the reverse direction, the operation difficulty is high. The centering effect of the lifting large rope is poor, and the guide sleeve inside the detection instrument is easy to wear.
And secondly, the position of the detecting instrument is fixed, the detection is carried out in the lifting process of the drilling machine, and the action that a lifting large rope passes through the detecting instrument is realized by the lifting of the drilling machine. The defect is that after the detection defect is found, the lifting rope is required to be replaced according to judgment, which is more troublesome and influences the construction progress. Part of the hoisting ropes are already threaded in the derrick, and the blind end cannot be detected, so that detection leakage is caused.
And thirdly, the steel wire rope is placed on the ground, a detector holds the instrument by hand and slides on the steel wire rope, three to four persons are required to lift the lifting big rope in a matching way due to the fact that the steel wire rope is too heavy, the detection efficiency is low, the labor intensity of the detector is high, and the detector is only suitable for carrying out local detection on a certain section of the lifting big rope. The centering effect of the lifting large rope is poor, and the guide sleeve of the detection instrument is easy to wear. The speed and the speed uniformity can not be controlled, and the detection precision is influenced.
Fourthly, a plurality of motor vehicles are matched with each other to suspend and straighten the lifting large rope in sections, and a detection instrument slides on the large rope to achieve the detection purpose. The large lifting rope has large bearing capacity, cannot be absolutely straightened, has a lower trend, has poor centering effect, easily causes abrasion of a guide sleeve in the detection instrument, and has troublesome integral operation and low efficiency.
In traditional wire rope detection, the defect mainly takes local defects such as broken wire, corrosion as the main thing, and in the wire rope detection patent of retrieval, only one row of local defect magnetic leakage sensor is inside to the magnetic leakage detection part, and this row of magnetic leakage sensor comprises a plurality of probes, if the sensor damages in the testing process, or plays to rise to have interference factors such as metallic impurity on the big rope, very easily causes the erroneous judgement.
