Description

Technical Field

[0001] This utility model belongs to the field of mechanical engineering technology, and in particular relates to a multi-angle drill pipe flaw detection support frame device. Background Technology

[0002] According to the published patent CN106393020A, a simple oil drill pipe support frame device includes a base, a support column, a fixing frame, and a pressure block. The fixing frame is connected to the upper surface of the base through the support column. The fixing frame has a rectangular frame structure, and a V-shaped groove is formed on the lower inner side of the fixing frame. The pressure block is connected to the upper inner side of the fixing frame through an adjustment mechanism. This device solves the problems of complex support frame structure, inconvenient adjustment, and cumbersome operation. However, it still has the following shortcomings:

[0003] The aforementioned equipment, when completed, achieved the effect of supporting drill rods of different specifications and being extremely easy to operate. However, the working environment or structural complexity of the drill rod may affect the flaw detection process. Some drill rods may develop irregular shapes due to usage or storage conditions, or the working environment may cause slight changes in the angle of the drill rod. At the same time, surface and internal defects of the drill rod may be distributed at different angles, but the aforementioned equipment cannot achieve the effect of angle adjustment. This may mean that the flaw detection equipment can only be fixed at a certain angle for detection, and cannot conduct a comprehensive inspection of the drill rod from multiple angles. As a result, some defects that are difficult to detect from a single angle are overlooked, affecting the accuracy and comprehensiveness of flaw detection. Therefore, we propose a multi-angle drill rod flaw detection support frame device. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-angle drill rod flaw detection support frame device. Through the adjustment mechanism and the fixing mechanism, it solves the problem that the above-mentioned equipment achieves the effect of supporting drill rods of different specifications and is extremely easy to operate. However, the working environment or structural complexity of the drill rod may affect the flaw detection process. Some drill rods may have irregular shapes due to usage or storage conditions, or the working environment may cause slight changes in the angle of the drill rod. At the same time, the surface and internal defects of the drill rod may be distributed at different angles. However, the above-mentioned equipment cannot achieve the effect of angle adjustment. This may mean that the flaw detection equipment can only be fixed at a certain angle for detection, and it is impossible to conduct a comprehensive inspection of the drill rod from multiple angles. As a result, some defects that are difficult to be found from a single angle are overlooked, affecting the accuracy and comprehensiveness of flaw detection.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a multi-angle drill rod flaw detection support frame device, including a base plate, a plurality of fixing plates are fixedly connected to the top outer wall of the base plate, and an adjustment mechanism is provided on the inner wall of the plurality of fixing plates.

[0007] The adjusting mechanism includes several lead screws, the outer walls of which are rotatably connected to the inner walls of fixed plates. Guide rods are fixedly connected to the inner walls of the fixed plates. Slider blocks are threadedly connected to the outer walls of the lead screws. The inner walls of the sliders are slidably connected to the outer walls of the guide rods. Connecting rods are rotatably connected to the outer walls of the sliders. Fixed frames are rotatably connected to the inner walls of the connecting rods at the ends away from the sliders. Support plates are fixedly connected to the top outer walls of the fixed frames. Ratchets are fixedly connected to the outer walls of the lead screws. Positioning plates are fixedly connected to the outer walls of the fixed plates. A fixing mechanism is provided on the top outer wall of the support plate.

[0008] Furthermore, each of the inner walls of the positioning plates is slidably connected with a pull rod, and each of the outer walls of the pull rods is fitted with a spring. The outer wall of one end of each pull rod near the lead screw is engaged with the outer wall of the ratchet.

[0009] Furthermore, the fixing mechanism includes a fixing box, the bottom outer wall of the fixing box is fixedly connected to the top outer wall of the support plate, a motor fixing plate is fixedly connected to the outer wall of the fixing box, and a first motor is fixedly connected to the outer wall of the motor fixing plate.

[0010] Furthermore, a worm gear is fixedly connected to the bottom output end of the first motor via a coupling, and several connecting plates are rotatably connected to the outer wall of the worm gear.

[0011] Furthermore, the outer walls of several connecting plates are fixedly connected to the outer wall of the fixing box, and the inner wall of the fixing box is rotatably connected with several bidirectional threaded rods.

[0012] Furthermore, the inner wall of the fixed box is fixedly connected with several limiting shafts, and the outer walls of the several bidirectional threaded rods are all threadedly connected with sliders.

[0013] Furthermore, the inner walls of several of the second sliders are slidably connected to the outer wall of the limiting shaft, and the top outer walls of several of the second sliders are fixedly connected with clamps.

[0014] Furthermore, worm gears are fixedly connected to the outer walls of several of the bidirectional threaded rods, and the outer walls of the worm gears mesh with the outer walls of the worm.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a slider. When the slider begins to move, it drives the connecting rod to rotate. At this time, the connecting rod rotates on the fixed frame, and the connecting rod lifts the support plate upward through the fixed frame, thus achieving the effect of adjusting the height of the drill rod. When the angle of the drill rod needs to be adjusted, simply pull the pull rod downward to completely disengage it from the ratchet, and then rotate the screw in the opposite direction to make one end of the support plate lower than the other end, thereby achieving the effect of angle and height adjustment. This ensures that the flaw detection equipment can effectively inspect in all directions, improving the comprehensiveness and accuracy of the detection.

[0017] 2. This utility model incorporates a worm gear. When the first motor starts running, it drives the worm gear to rotate. When the worm gear rotates, it drives the worm wheel to rotate. At this time, the worm wheel drives the two sliders to move bidirectionally through the limiting shaft. When the sliders move, they synchronously drive the clamping plate to move along the same trajectory. When the clamping plate contacts the drill rod, it achieves the effect of clamping and fixing the drill rod, ensuring that the drill rod is firmly fixed during the flaw detection process and preventing the drill rod from shaking or moving during inspection. This helps to improve the stability and accuracy of the flaw detection process and reduce errors.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5As shown, this utility model is a multi-angle drill pipe flaw detection support frame device, including a base plate 1. Several fixed plates 101 are fixedly connected to the top outer wall of the base plate 1. The fixed plates 101 are used to support and fix the device, making it more stable during use. An adjustment mechanism 2 is provided on the inner wall of the fixed plates 101. The adjustment mechanism 2 includes several lead screws 201. The outer walls of the lead screws 201 are rotatably connected to the inner walls of the fixed plates 101. Guide rods 202 are fixedly connected to the inner walls of the fixed plates 101. The lead screws 201 drive the parts to move, and the guide rods 202 assist the parts in moving in the correct direction. Slider blocks 203 are threadedly connected to the outer walls of the lead screws 201. The inner walls of the sliders 203 are slidably connected to the outer walls of the guide rods 202. Connecting rods 204 are rotatably connected to the outer walls of the sliders 203. When the sliders 203 start to move, they drive the connecting rods 204 to move along the same trajectory. Several connecting rods 204 have fixed frames 205 rotatably connected to the inner walls of their ends away from the slider 203. Support plates 206 are fixedly connected to the top outer walls of the fixed frames 205. When the connecting rods 204 move a certain distance, they will lift the support plates 206 upwards via the fixed frames 205. Ratchets 207 are fixedly connected to the outer walls of several lead screws 201. The ratchet 207, in conjunction with subsequent parts, achieves the effect of limiting the movement of the lead screws 201. Each fixed plate 101 has a positioning plate 208 fixedly connected to its outer wall. The top outer wall of the support plate 206 is provided with a fixing mechanism 3. Each positioning plate 208 has a pull rod 209 slidably connected to its inner wall. Each pull rod 209 has a spring 210 sleeved on its outer wall. The positioning plate 208 is used to support and limit the pull rod 209 to prevent it from falling off after use. The outer wall of one end of each pull rod 209 near the lead screw 201 is engaged with the outer wall of the ratchet 207.

[0029] The fixing mechanism 3 includes a fixing box 301. The bottom outer wall of the fixing box 301 is fixedly connected to the top outer wall of the support plate 206. The fixing box 301 is used to support and limit the internal parts, making them more stable during operation. A motor fixing plate 302 is fixedly connected to the outer wall of the fixing box 301. A first motor 310 is fixedly connected to the outer wall of the motor fixing plate 302. The motor fixing plate 302 is used to fix and support the first motor 310, making the first motor 310 more stable during use. The bottom output end of 310 is fixedly connected to a worm gear 303 via a coupling. Several connecting plates 304 are rotatably connected to the outer wall of the worm gear 303. When the first motor 310 drives the worm gear 303 to rotate, the worm gear 303 will rotate inside the connecting plates 304. The connecting plates 304 provide support for the worm gear 303 to prevent it from falling off during use. The outer walls of the several connecting plates 304 are fixedly connected to the outer wall of the fixed box 301. Several bidirectional threaded rods 305 are rotatably connected to the inner wall of the fixed box 301.

[0030] The inner wall of the fixed box 301 is fixedly connected with several limiting shafts 306. The outer walls of several bidirectional threaded rods 305 are threadedly connected with sliders 307. When the bidirectional threaded rods 305 start to rotate, they will drive two sliders 307 to move bidirectionally through the limiting shafts 306. The inner walls of the sliders 307 are slidably connected to the outer walls of the limiting shafts 306. The top outer walls of the sliders 307 are fixedly connected with clamping plates 308, which are used to clamp and fix the drill rod to prevent it from moving during use. The outer walls of the bidirectional threaded rods 305 are fixedly connected with worm gears 309. The outer walls of the worm gears 309 are meshed with the outer walls of the worm 303. When the worm 303 starts to rotate, it will drive the worm gears 309 to rotate. When the worm gears 309 start to rotate, they will drive the bidirectional threaded rods 305 to rotate.

[0031] One specific application of this embodiment is:

[0032] When the operator needs to use the equipment, first place the drill rod on the fixing box 301, positioning it between multiple clamping plates 308. Then, start the first motor 310 via the controller. When the first motor 310 starts running, it drives the worm gear 303 to rotate. When the worm gear 303 starts rotating, it drives the worm wheel 309 to rotate. At this time, the worm wheel 309 drives the two sliders 307 to move bidirectionally through the limiting shaft 306. When the sliders 307 start moving, they synchronously drive the clamping plates 308 to move along the same trajectory. When the clamping plates 308 contact the drill rod, the drill rod is clamped and fixed. Then, rotate the lead screw 201. When the lead screw 201 starts rotating, it drives the ratchet 207 to rotate. When the ratchet 207 starts rotating, it compresses the pull rod 209. When the pull rod 209 is compressed, it slides in the positioning plate 208. During the sliding process of the pull rod 209, it compresses the spring 210. When the ratchet 207... When the pull rod 209 is no longer compressed, the spring 210's rebound force will cause the pull rod 209 to reset. Under the action of the spring 210, the pull rod 209 intermittently engages in the tooth groove. When the lead screw 201 reverses, the teeth on the ratchet 207 will block one end of the pull rod 209. At this time, the ratchet 207 will remain stationary, thus achieving the effect of unidirectional rotation and reverse locking. When the lead screw 201 rotates, it will drive the slider 203 to move. When the slider 203 starts to move, it will drive the connecting rod 204 to rotate. At this time, the connecting rod 204 will rotate on the fixed frame 205. At this time, the connecting rod 204 will lift the support plate 206 upward through the fixed frame 205, thus achieving the effect of adjusting the drill rod angle. When the drill rod angle needs to be adjusted, simply pull the pull rod 209 downward to completely disengage it from the ratchet 207, and then rotate the lead screw 201 in the opposite direction so that one end of the support plate 206 is lower than the other end to achieve the effect of angle adjustment.
