[0047] In the oil rig system, it is necessary to prevent the traveling block from colliding with other components. Often when using a mechanical anti-collision structure, it is also necessary to determine the position of the traveling block through calculation, so as to achieve anti-collision control.

[0048] In the prior art, the change in wire rope length is calibrated by detecting the rotation of the drum, thereby creating a corresponding relationship with the change in height of the traveling block. However, in the existing height judgment, the calibration value of the previous test is often used for matching. Once the suspended weight on the traveling block changes, the calculated height and the actual height will not match, and the correct position cannot be obtained.

[0049] The invention provides a traveling carriage system of an oil drilling rig, comprising a drum, a rope, a traveling carriage system and a controller; one end of the rope is wound around the drum; and the traveling carriage system is connected to the other end of the rope.

[0050] In the height detection method of the traveling carriage system of the oil drilling rig provided by the present invention, the extended or retracted length of the rope is calculated according to the number of rotations of the drum, and the calculated height of the traveling carriage system after following the activity is calculated. At this time, the calculated height is only an ideal situation in which the rope is not deformed. Therefore, it is also necessary to obtain the compensation coefficient of the traveling carriage system and determine the actual height of the traveling carriage based on the compensation coefficient.

[0051] It should be noted that, in this embodiment, the number of rotations of the drum is determined by an encoder.

[0052] Furthermore, the traveling block system includes a traveling block, a lower coupling and an elevator which are arranged in sequence from top to bottom; the oil drilling rig traveling block system also includes a visual detection device for detecting the top height of the lower coupling. In this embodiment, the visual detection device detects the position of the lower coupling, and then the position of the lowest point of the traveling block system can be obtained by subtracting the height of the lower coupling and the height of the elevator, so as to judge whether the traveling block system will cause a collision.

[0053] In this embodiment, the visual detection device is a camera.

[0058] The actual height of the traveling block is determined according to the calculated height and the compensation coefficient.

[0059] Optionally, determining the telescopic length of the rope according to the number of rotations of the drum includes:

[0060] obtaining the overall height of the drum and the rope, the rope diameter of the rope, and the number of stacked layers of the rope;

[0061] Obtaining the actual diameter of the drum according to the overall height, the rope diameter and the number of stacked layers;

[0062] The telescopic length of the rope is determined according to the actual diameter and the number of rotations.

[0063] Optionally, the obtaining the compensation coefficient includes:

[0064] Obtaining the current load of the traveling carriage system and the test load during the test;

[0065] Obtaining a load factor of the rope according to the current load and the test load;

[0067] The compensation coefficient is obtained according to the elastic variation coefficient and the load system.

[0068] Optionally, the elastic variation coefficient of the rope is obtained by the following steps:

[0069] After the oil rig test begins, determining the test telescopic length of the rope according to the test rotation number of the drum;

[0070] According to the test telescopic length and the transmission distance coefficient of the rope, the test calculated height of the traveling carriage system is obtained;

[0071] Obtaining the actual test height of the traveling carriage system;

[0072] The elastic variation coefficient of the rope is determined according to the test calculated height and the test actual height.

[0073] Optionally, the traveling block system includes a traveling block, a lower coupling and an elevator arranged in sequence from top to bottom;

[0074] The step of obtaining the actual test height of the traveling carriage system comprises:

[0075] Obtaining the coupling length and the elevator length of the lower coupling and the elevator respectively;

[0076] identifying the top height of the lower coupling;

[0077] The bottom end height of the traveling block system is determined according to the top end height, the coupling length and the elevator length, and the bottom end height is used as the actual height.

[0078] Optionally, the oil rig traveling system includes a visual detection device;

[0079] The step of identifying the top height of the lower coupling comprises:

[0080] The top height of the lower coupling is obtained by the visual detection device.

[0081] According to the above oil rig traveling block system, please refer to Figure 1 The present invention also provides a method for detecting the height of a traveling carriage system of an oil drilling rig, the method comprising the following steps:

[0082] S10, after the oil drilling rig starts working, determining the telescopic length of the rope according to the number of rotations of the drum;

[0083] The rope is wound around the drum, and the rope can be released or reeled in by rotating the drum, thereby changing the telescopic length of the rope, thereby controlling the traveling vehicle system on the rope.

[0084] S20, obtaining a calculated height of the traveling carriage system according to the telescopic length and the transmission distance coefficient of the rope;

[0085] The telescopic length of the rope and the height calibration of the traveling carriage system are calculated. The height of the traveling carriage system can be accurately calculated by only obtaining the telescopic length of the rope.

[0086] S30, obtaining a compensation coefficient of the traveling block system;

[0087] S40, determining the actual height of the traveling carriage system according to the calculated height and the compensation coefficient.

[0088] The present invention provides a method for detecting the height of a traveling carriage system of an oil drilling rig. After the oil drilling rig starts working, the extended or retracted length of the rope is calculated according to the number of rotations of the drum. Due to the winding method between the rope and the traveling carriage system, a conversion amount will be generated when the extension and contraction length of the rope drives the traveling carriage system to move. Therefore, according to the transmission distance coefficient of the rope, the calculated height of the traveling carriage system after following the activity can be calculated. At this time, the calculated height is only an ideal situation in which the rope is not deformed. Therefore, it is also necessary to obtain the compensation coefficient of the traveling carriage system and determine the actual height of the traveling carriage according to the compensation coefficient.

[0089] Furthermore, S10 includes:

[0090] S11, obtaining the overall height of the drum and the rope, the rope diameter of the rope, and the number of stacked layers of the rope;

[0091] The rope is wound around the drum, and the ropes are stacked and wound around the drum. Since the length needs to be determined based on the rotation of the drum, the diameter of the drum needs to be obtained.

[0092] S12, obtaining the actual diameter of the drum according to the overall height, the rope diameter and the number of stacked layers;

[0093] Among them, the height occupied by the telescopic device is obtained by the rope diameter and the number of stacking layers, and then the actual diameter of the drum is obtained by subtracting the occupied height from the overall height. Only the overall height needs to be measured, and the measurement method is simple.

[0094] S13. Determine the telescopic length of the rope according to the actual diameter and the number of rotations.

[0095] According to the actual diameter, the circumference of the drum can be calculated, and according to the corresponding rotation relationship, the extension and contraction length of the rope during the rotation of the drum can be calculated. The calculation method is simple, and the length of the rope can be obtained only according to the number of rotations, which is convenient for obtaining the length change of the rope in real time.

[0096] It should be noted that step S20 calculates the calculated height of the traveling carriage system according to the telescopic length, obtains the displacement distance of the traveling carriage system relative to the initial position according to the rope length of the rope, and then obtains the calculated height; wherein, the method of obtaining the calculated height through the telescopic length of the telescope already exists in the prior art and will not be repeated here.

[0097] On the other hand, step S30 includes:

[0098] S31, obtaining the current load of the traveling carriage system and the test load during the test;

[0099] Among them, since the rope will undergo elastic deformation, it is necessary to obtain the deformation under different loads according to different loads. A test is first performed, and the test load during the test is used as a basis to compare the current load with the test load, so as to determine the load factor of the rope in proportion.

[0100] S32, obtaining a load factor of the rope according to the current load and the test load;

[0101] S33, obtaining the elastic variation coefficient of the rope;

[0102] The rope itself has a certain elastic variation coefficient. When a load is pulled, elastic deformation will occur. The difference between theory and practice needs to be taken into account. Therefore, the actual elastic variation coefficient needs to be obtained.

[0103] S34. Obtain the compensation coefficient according to the elastic variation coefficient and the load system.

[0104] In this embodiment, the compensation system is comprehensively acquired based on the elastic variation coefficient and the load system, so as to compensate the calculated height according to the compensation coefficient to determine the actual height of the traveling block system.

[0105] Furthermore, the elastic variation coefficient of the rope is obtained by the following steps:

[0106] S331, after the oil rig test starts, determining the test telescopic length of the rope according to the test rotation number of the drum;

[0107] During the test, the length of the rope is also determined by the number of rotations. The expansion and contraction change of the rope can be determined by measuring the rotation of the drum, and the detection method is simple.

[0108] S332, obtaining a test calculation height of the traveling carriage system according to the test telescopic length and the transmission distance coefficient of the rope;

[0109] The telescopic length of the rope and the height calibration of the traveling carriage system are calculated. The height of the traveling carriage system can be accurately calculated by only obtaining the telescopic length of the rope.

[0110] S333, obtaining the actual test height of the traveling carriage system;

[0111] S334. Determine the elastic variation coefficient of the rope according to the test calculated height and the test actual height.

[0112] In the present application, the actual test height of the traveling car system is obtained, and the elastic variation coefficient of the rope is calculated based on the comparison between the test calculated height and the actual test height, and the law satisfied by the normal deformation of the rope under the test conditions is determined, so as to obtain the elastic variation coefficient.

[0113] In this application, step S333 includes:

[0114] S3331, respectively obtaining the coupling length and the elevator length of the lower coupling and the elevator;

[0115] Since the traveling block system includes a traveling block, a lower coupling and an elevator which are arranged in sequence from top to bottom, the elevator is actually the lowest point of the traveling block system. In order to ensure that no collision occurs at the lowest point, it is necessary to obtain the lengths of the lower coupling and the elevator so as to calculate the lowest point.

[0116] S3332, identifying the top height of the lower coupling;

[0117] Among them, what is identified is the top height of the lower coupling, that is, the lower end of the traveling block. It is easy to identify here, and there is an obvious staggered seam for identification. At the same time, it is only necessary to eliminate the influence of the lower coupling and the hanging card, and there is less error interference.

[0118] S3333. Determine the bottom end height of the traveling block system according to the top end height, the coupling length and the hanging card length, and use the bottom end height as the actual test height.

[0119] In this embodiment, the height of the lowest point of the traveling block system is obtained by subtracting the coupling length and the elevator length from the top height, and this is used as the actual height.

[0120] Specifically, in this embodiment, the identifying the top height of the lower coupling comprises:

[0121] The top height of the lower coupling is obtained by the visual detection device.

[0122] The height position is determined by visual recognition, which is simple to operate and mature in technology. It only requires image analysis and will not be elaborated here.

[0123] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
