Description

Technical Field

[0001] This utility model relates to the technical field of drill pipe sensing devices, and in particular to a power catwalk conveyor arm sensing drill pipe device. Background Technology

[0002] A powered catwalk is a device that transports drill pipe, casing, and drill collars from the surface to the drilling platform, and it is widely used in oilfields both domestically and internationally. In the development of intelligent drilling rigs, drill pipe status detection is a crucial step in achieving unmanned, one-button drilling. The entry of the drill pipe into the delivery arm is the first step in the entire automated drilling rig, and drill pipe position detection is fundamental to enabling coordinated operation and real-time data exchange among multiple devices on the drilling rig.

[0003] Most existing drill pipe detection devices use continuity sensors to detect whether the drill pipe has entered the power catwalk. However, there are generally two situations where the drill pipe has entered the catwalk: one is that the entire drill pipe has entered the catwalk, in which case the drill pipe is correctly positioned and subsequent steps can be performed; the other is that one end of the drill pipe has entered the catwalk, while the other end has not entered due to jamming or other reasons. This is an abnormal situation, and subsequent steps cannot be performed. However, existing drill pipe detection devices cannot distinguish this abnormal situation, resulting in the detection result still showing that the drill pipe has entered the catwalk, which is inaccurate. In addition, the oil carried by the drill pipe itself will stick to the continuity sensor, and long-term use will affect the sensitivity of the continuity sensor, further affecting the accuracy of the detection result.

[0004] Therefore, it is necessary to propose a power catwalk conveying arm induction drill pipe device to improve the accuracy of drill pipe detection results. Utility Model Content

[0005] The purpose of this invention is to solve the problem of inaccurate detection results of existing drill pipe detection devices, and a power catwalk conveying arm sensing drill pipe device is provided.

[0006] The technical solution of this utility model is:

[0007] A power catwalk conveying arm induction drill rod device includes a slide rail inside the conveying arm. The slide rail is laid along a V-shaped groove on the conveying arm and is located outside the V-shaped groove. At least two proximity switches are provided inside the slide rail, with the two proximity switches located at opposite ends of the V-shaped groove. The proximity switches are fixedly connected to a sliding device, which is located inside the slide rail and slidably connected to the slide rail. A limiting member is also provided inside the slide rail to limit the movement of the sliding device. When the limiting member protrudes, the sliding device is relatively fixed to the slide rail.

[0008] Furthermore, the sliding device includes a slider, a connecting flange, a nylon plate, and a sensor mounting plate. The slider is slidably connected to the slide rail, the connecting flange is fixedly connected to the slider, the nylon plate is fixedly connected to the connecting flange, the sensor mounting plate is fixedly connected to the nylon plate, and the proximity switch is fixedly connected to the sensor mounting plate. The slider sliding within the guide rail allows for easy adjustment of the proximity switch position, thus adapting to drill pipes of different lengths. The connecting flange is used to fix the slider. The nylon plate can act as a shock absorber, effectively extending the service life of the proximity switch. The sensor mounting plate is used to fix the nylon plate to the proximity switch.

[0009] Furthermore, the limiting components are evenly distributed along the slide rail, and the interval between two adjacent limiting components matches the size of the slider. When the limiting component protrudes, it can simultaneously limit the slider on both sides, thereby locking the slider and fixing the position of the proximity switch on the guide rail.

[0010] Furthermore, an oil guide groove is provided on one side of the slide rail near the bottom of the V-shaped groove. The oil guide groove is parallel to the V-shaped groove and can effectively collect the oil adhering to the drill pipe, preventing the oil from adhering to the proximity switch when it moves around randomly.

[0011] Furthermore, a collection tank is provided at one end of the oil guide tank. The collection tank is square and has an openable valve at the bottom. The collection tank is the outlet for the oil in the oil guide tank and can collect the oil in the oil guide tank. The valve can be opened to discharge the oil when there is too much oil in the collection tank.

[0012] Furthermore, a sliding oil filter plate is installed inside the oil guide groove. The oil filter plate slides along the oil guide groove and pushes the oil into the collection groove. Because the oil is viscous and the environment is relatively harsh, impurities often mix with the oil, causing the oil to solidify in the oil guide groove and eventually block it. Therefore, workers can push the oil filter plate to manually force the solidified oil in the oil guide groove to the collection groove, ensuring the cleanliness of the oil guide groove and realizing the collection of oil.

[0013] Furthermore, the oil filter plate is equipped with a brush with bristles perpendicular to the oil guide groove. The brush can reach small areas or remote crevices in the oil guide groove, thereby improving the cleaning ability of the oil filter plate.

[0014] Furthermore, the limiting component is a bolt.

[0015] Furthermore, the proximity switch is connected to a control system.

[0016] This invention relates to a power catwalk conveyor arm induction drill rod device. A proximity switch is installed at each end of the V-shaped groove. When the drill rod enters the V-shaped groove of the conveyor arm, a high-frequency magnetic field is generated in the detection coil of the proximity switch. Due to electromagnetic induction, eddy currents are generated inside the drill rod, absorbing the oscillating current of the proximity switch, causing a change in its amplitude. The connected control system immediately receives this signal and transmits the detection signal to the driller's cabin via a data transmission line. After processing by the control system, it can determine whether the drill rod has entered the V-shaped groove of the conveyor arm based on the feedback signal. When only the proximity switch at one end of the V-shaped groove generates an oscillating current, the control system will... This situation is considered abnormal and will not indicate that the drill pipe has entered the V-groove, thus effectively improving the accuracy of drill pipe detection. Furthermore, the slide rail design allows for flexible adjustment of the distance between the proximity switches at both ends of the V-groove, accommodating drill pipes of different lengths and further ensuring the accuracy of the detection results. Moreover, the proximity switches are located within the slide rail, which effectively prevents oil from the drill pipe from adhering to the switches, thus avoiding oil contamination and reduced detection accuracy. Compared to traditional technologies, this solution improves the accuracy of the drill pipe detection device and ensures the accuracy of the detection results. Attached Figure Description

[0024] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0025] Example 1:

[0026] like Figure 1 and Figure 2 As shown, this embodiment provides a power catwalk conveying arm induction drill rod device, including a slide rail 2 disposed inside the conveying arm 1. The slide rail 2 is laid along the V-shaped groove 3 on the conveying arm 1 and is located outside the V-shaped groove 3. The slide rail 2 and the V-shaped groove 3 are fixedly connected by screws. At least two proximity switches 4 are provided inside the slide rail 2. The two proximity switches 4 are respectively located at both ends of the V-shaped groove 3. The proximity switches 4 are fixedly connected to a sliding device. The sliding device is located inside the slide rail 2 and is slidably connected to the slide rail 2. A limiting member 5 is also provided inside the slide rail 2 to limit the sliding device. When the limiting member 5 protrudes, the sliding device is relatively fixed to the slide rail 2.

[0027] Preferred, such as Figure 2 As shown, the sliding device includes a slider 6, a connecting flange 7, a nylon plate 8, and a sensor fixing plate 9. The slider 6 is slidably connected to the slide rail 2, the connecting flange 7 is fixedly connected to the slider 6 with screws, the nylon plate 8 is fixedly connected to the connecting flange 7 with screws, the sensor fixing plate 9 is fixedly connected to the nylon plate 8 with screws, and the proximity switch 4 is fixedly connected to the sensor fixing plate 9 with screws. The slider 6 slides within the guide rail, which allows the proximity switch 4 to be easily adjusted to accommodate drill rods of different lengths. The connecting flange 7 is used to fix the slider 6. The nylon plate 8 can act as a shock absorber, effectively extending the service life of the proximity switch 4. The sensor fixing plate 9 is used to fix the nylon plate 8 to the proximity switch 4.

[0028] Preferred, such as Figure 1 As shown, the limiting members 5 are evenly distributed along the slide rail 2. The interval between two adjacent limiting members 5 matches the size of the slider 6. When the limiting member 5 is not protruding, the slider 6 will not be blocked and can slide in the slide rail 2. When the limiting member 5 protrudes, it can limit both sides of the slider 6 at the same time, thereby locking the slider 6 and fixing the position of the proximity switch 4 on the guide rail.

[0029] Preferred, such as Figure 3 As shown, an oil guide groove 10 is provided on the side of the slide rail 2 near the bottom of the V-shaped groove 3. The oil guide groove 10 is parallel to the V-shaped groove 3. The oil guide groove 10 can effectively collect the oil adhering to the drill rod and prevent the oil from adhering to the proximity switch 4 when it moves randomly.

[0030] Preferred, such as Figure 4 As shown, one end of the oil guide groove 10 is provided with a collection groove 11. The collection groove 11 is square and has an openable and closable valve 12 at its bottom. The collection groove 11 is the outlet of the oil in the oil guide groove 10, which can collect the oil in the oil guide groove 10. The valve 12 can be opened to discharge the oil when there is too much oil in the collection groove 11.

[0031] Preferred, such as Figure 5 As shown, an oil guide trough 10 is equipped with an oil filter plate 13 that slides along a guide rail. The oil filter plate 13 slides along the oil guide trough 10 and pushes the oil into the collection tank 11. Because the oil is viscous and the environment is relatively harsh, impurities often mix with the oil, causing the oil to solidify in the oil guide trough 10 and eventually block it. Therefore, workers can push the oil filter plate 13 to manually force the solidified oil in the oil guide trough 10 to the collection tank 11, ensuring the cleanliness of the oil guide trough 10 and realizing the collection of the oil.

[0032] Preferred, such as Figure 5 As shown, a brush 14 is fixedly installed on the oil filter plate 13 with screws. The bristles on the brush 14 are perpendicular to the oil guide groove 10. The brush 14 can brush the small parts or remote gaps in the oil guide groove 10, thereby improving the cleaning ability of the oil filter plate 13.

[0033] Preferably, the limiting element 5 is a bolt, and preferably, the proximity switch 4 is connected to the control system 15.

[0034] When using, such as Figure 6 and Figure 3 As shown, a proximity switch 4 is installed at each end of the V-groove 3. When the drill pipe enters the V-groove 3 of the conveying arm 1, a high-frequency magnetic field is generated in the detection coil of the proximity switch 4. Due to electromagnetic induction, eddy currents are generated inside the drill pipe, absorbing the oscillating current of the proximity switch 4, and its amplitude will change. The control system 15 connected to it will immediately receive this signal and then transmit the detection signal to the driller's cabin through the data transmission line. After processing by the control system 15, it can determine whether the drill pipe has entered the V-groove 3 of the conveying arm 1 based on the feedback signal. When only the proximity switch 4 at one end of the V-groove 3 generates an oscillating current, the control system 15 will determine this situation. This is an abnormal situation and will not indicate that the drill rod has entered the V-groove 3, thus effectively improving the accuracy of drill rod detection. On the other hand, the setting of the slide rail 2 can flexibly adjust the distance between the proximity switches 4 at both ends of the V-groove 3, thereby adapting to the detection of drill rods of different lengths and further ensuring the accuracy of the detection results. Moreover, the proximity switches 4 are located inside the slide rail 2, and the presence of the slide rail 2 will effectively prevent oil on the drill rod from adhering to the proximity switches 4, thereby avoiding the proximity switches 4 from being contaminated by oil and reducing their detection accuracy. Compared with traditional technology, this technical solution improves the detection accuracy of the drill rod detection device and ensures the accuracy of the detection results.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model.
