Description

Technical Field

[0001] This application relates to the field of engineering testing equipment technology, and in particular to a testing device. Background Technology

[0002] Drill pipe is a hollow tubular component in drilling operations that connects surface equipment to downhole drilling tools. It is used to transmit power, transport drilling media, extend drilling depth, and support downhole tools. Before being lowered into the well, drill pipe undergoes internal inspection to determine if it contains foreign objects or damage. Furthermore, an industrial endoscope is typically used to inspect the inner wall of the drill pipe. A probe is inserted into the inner wall channel via a cable, allowing the probe to acquire images of corrosion, cracks, and other defects on the inner wall.

[0003] Because the drill pipe is long and slender, the required endoscope cable is also quite long. Longer cables are prone to tangling and twisting, which can lead to cable malfunction or jamming, preventing the endoscope from properly performing its internal wall examinations. Summary of the Invention

[0004] The purpose of this application is to provide a detection device to improve or solve the aforementioned technical problems existing in the prior art.

[0005] This application provides a detection device for detecting a test piece. The detection device includes a base, an endoscope, a first drive member, a second drive member, a first brake member, a second brake member, a cable storage reel, and a control member. The first drive member, the second drive member, and the cable storage reel are mounted on the base. The endoscope includes a body and a cable connected to each other. The cable is electrically connected to the body. The first drive member drives the cable to move the body. The first brake member is disposed between the cable storage reel and the first drive member and is used to release or brake the cable. The cable storage reel is rotatably disposed relative to the base and is used to store the cable. The second drive member drives the cable storage reel and the second brake member is used to release or brake the cable storage reel. The control member is electrically connected to the first drive member, the second drive member, the first brake member, and the second brake member.

[0006] The technical solution adopted in this application achieves the following beneficial effects: the control unit electrically connects to and controls the first driving unit, the second driving unit, the first braking unit, and the second braking unit. The driving unit and the cable storage tray are mounted on the base. The endoscope includes an interconnected body and cables. The first driving unit drives the cables to move the body, ensuring that the body can move to a deeper level inside the object under test. The body can acquire image information inside the object under test, and the cable storage tray can store the cables. When the first driving unit drives the cables, the cables can extend from the cable storage tray to drive the body's movement. At the same time, the cable storage tray can also avoid problems such as cable tangling when idle.

[0007] Compared to existing technologies, the first and second braking components of this application can brake the cable and the cable storage reel respectively. This redundancy prevents cable loosening or tangling due to the failure of either component. During use, the first and second braking components can be released simultaneously to ensure smooth cable delivery by both the first and second driving components. After detection, the first and second driving components synchronously drive the cable to smoothly reel it onto the cable storage reel. During this process, the first braking component brakes the cable, while the second driving component continues to drive the cable storage reel to tighten it. This gradual tightening prevents every loop of cable on the reel from being taut, thus avoiding tangling or twisting. Attached Figure Description

[0011] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0012] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0013] In existing technologies, long cables are prone to problems such as tangling and twisting. This is because cables are flexible wire bundles that are wound around a reel. If the previous loop of cable is not tightly wound and becomes misaligned, the subsequent loops of cable will overlap with the previous loop, leading to tangling and twisting. This can cause the cable to malfunction or become stuck, preventing the endoscope from performing its internal wall inspection work properly.

[0014] This application provides a detection device 100; please refer to [link / reference]. Figure 1 The detection device 100 is used to detect the part to be tested. The part to be tested includes, but is not limited to, drill pipes, delivery pipes, etc. The detection device 100 includes a base 110, an endoscope 120, a first drive component 130, a second drive component 140, a first brake component 150, a second brake component 160, a wire storage reel 170, and a control component. The first drive component 130, the second drive component 140, the first brake component 150, the second brake component 160, and the wire storage reel 170 are mounted on the base 110. The first drive component 130 is drive-connected to the endoscope 120, and the second drive component 140 is drive-connected to the wire storage reel 170.

[0015] The control unit is electrically connected to the first drive unit 130, the second drive unit 140, the first brake unit 150, and the second brake unit 160. The control unit can control the first drive unit 130, the second drive unit 140, the first brake unit 150, and the second brake unit 160. The controller may include a processor and a memory. The processor may include a processing chip or a microcontroller, and the memory stores control instructions for the processor to execute control operations.

[0016] Please see Figure 2 The endoscope 120 includes a body 121 and a cable 122 connected to each other. The cable 122 is electrically connected to the body 121. A first drive member 130 drives the cable 122 to move the body 121. The cable 122 may be flexible, allowing it to drive the body 121 into the object to be inspected. The body 121 includes an illumination module and a camera module. The illumination module includes a light-emitting chip and illuminates the interior of the object to be inspected. The camera module can acquire image information from within the object. The body 121 is provided with a detection head and a protective part disposed on the detection head. The protective part may be a metal part with wear resistance and surrounds the periphery of the detection head to prevent friction or collision between the detection head and the inner wall of the object to be inspected. Simultaneously, the protective part supports the detection head so that it is positioned on the central axis of the object to be inspected. After excessive wear of the protective part, only the protective part needs to be replaced, reducing replacement costs.

[0017] Please refer to the previous document. Figure 1A first braking element 150 is disposed between the cable storage reel 170 and the first driving element 130, and is used to release or brake the cable 122. The cable storage reel 170 is rotatably disposed relative to the base 110 and is used to store the cable 122. The cable 122 can be wound around the cable storage reel 170. A second driving element 140 is drively connected to the cable storage reel 170, and a second braking element 160 is used to release or brake the cable storage reel 170. The driving element and the cable storage reel 170 are mounted on the base 110. The endoscope 120 includes a body 121 and a cable 122 connected to each other. The first driving element 130 is used to drive the cable 122 to move the body 121, ensuring that the body 121 can move to a deeper part of the object to be inspected. The cable storage reel 170 can store the cable 122. When the first drive member 130 drives the cable 122, the cable 122 can extend from the cable storage reel 170 to drive the body 121 to move. At the same time, the cable storage reel 170 can also avoid problems such as the cable 122 getting tangled when idle.

[0018] Understandably, the first braking element 150 and the second braking element 160 can brake the cable 122 and the cable storage reel 170 respectively. This redundancy prevents the cable 122 from becoming loose or tangled due to the failure of either the first or second braking element 150. During use, the first and second braking elements 150 and 160 can be released simultaneously to ensure that the first and second driving elements 130 and 140 can smoothly deliver the cable 122. After the test is completed, the first and second driving elements 130 and 140 synchronously drive the cable 122 so that it can be smoothly coiled onto the cable storage reel 170. During this period, the first braking element 150 brakes the cable 122, and the second driving element 140 continues to drive the cable storage reel 170 to tighten the cable 122. This allows the cable 122 on the cable storage reel 170 to gradually tighten, preventing each loop of cable 122 on the reel from being taut and avoiding problems such as tangling or twisting.

[0019] In the embodiments of this application, please refer to Figure 3The first driving component 130 may include a first driving unit 131, a first conveying unit 132, and a second conveying unit 133. The first conveying unit 132 and the second conveying unit 133 are movably mounted on the base 110, forming a first channel for the cable 122 to pass through. The first driving unit 131 is driven by at least one of the first conveying unit 132 and the second conveying unit 133, and drives the body 121 to move through friction transmission with the cable 122 via the first and second conveying units 132 and the second conveying unit 133. By utilizing friction to transmit the power of the first driving unit 131 to the cable 122, stable driving of the body 121 can be achieved without additional clamping and fixing structures. During the transmission process, no hard damage will be caused to the cable 122. At the same time, it adapts to the friction transmission requirements of cables 122 of different diameters, ensuring the reliability of power transmission.

[0020] Please continue reading. Figure 3 At least one of the first conveying unit 132 and the second conveying unit 133 includes a first drive shaft 134, a second drive shaft 135, and a first transmission belt 136. For ease of understanding, the following description uses the first conveying unit 132 as an example. At least one of the first drive shaft 134 and the second drive shaft 135 is connected to the first drive unit 131. The first transmission belt 136 is connected between the first drive shaft 134 and the second drive shaft 135 and makes frictional contact with the cable 122. The first drive shaft 134 drives the second drive shaft 135 through the first transmission belt 136 and synchronously drives the cable 122. In other words, the first drive shaft 134 and the second drive shaft 135 are linked by the first transmission belt 136, and the transmission belt makes direct frictional contact with the cable 122. When the first drive unit 131 drives the first drive shaft 134 to rotate, the transmission belt synchronously drives the second drive shaft 135 to rotate, so that the contact area between the transmission belt and the cable 122 forms a uniform and continuous driving force. This avoids the problem of uneven force on the cable 122 caused by single-point drive, significantly improves the stability and smoothness of the cable 122 driving process, and reduces the phenomenon of cable 122 deviation or jamming. While increasing the contact area, this also has the function of calibrating the cable 122, preventing the cable 122 from twisting or bending.

[0021] In another implementation, please refer to [link / reference needed]. Figure 3The first driving component 130 also includes a third conveying unit 137 and a fourth conveying unit 138, which are movably mounted on the base 110. The third and fourth conveying units 137 and 138 abut against the cable 122 in a direction of mutual proximity. The third and fourth conveying units 137 and 138 abut against the cable 122 along its first diameter, while the first and second conveying units 132 and 133 abut against the cable 122 along its second diameter. The first and second diameters intersect. Through bidirectional abutment in different diameter directions, a closed-loop limiting effect is formed on the cable 122, enabling real-time correction of the cable 122's spatial orientation. This ensures the cable 122 remains vertical, preventing bending or deviation due to its own flexibility or external forces. It also ensures tight contact between the cable 122 and the friction transmission surface of the conveying unit, eliminating transmission failure caused by cable bending.

[0022] Please see Figure 4At least one of the first braking element 150 and the second braking element 160 includes a mounting bracket 151, a first clamping part 152, a second clamping part 153, and a second drive unit 154. The second drive unit 154 can be a cylinder or a drive motor, etc., and is not limited thereto. For ease of understanding, the following description uses the first braking element 150 as an example. The second drive unit 154 is mounted on the mounting bracket 151. A second channel for the cable 122 to pass through is formed between the first clamping part 152 and the second clamping part 153. At least one of the first clamping part 152 and the second clamping part 153 is slidably disposed relative to the mounting bracket 151 and is driveably connected to the second drive unit 154. Driven by the second drive unit 154, the first clamping part 152 and the second clamping part 153 are moved closer to or further away from each other. In one case, the second drive unit 154 can be a cylinder, and the mounting bracket 151 is provided with an air passage and connected to an external air pump, etc. The airway has a first branch and a second branch, which are respectively connected to the two ends of the second drive unit 154. Exemplarily, the airflow within the first and second branches drives the second drive unit 154 to move in two opposite directions, thereby driving at least one of the first clamping portion 152 and the second clamping portion 153. Alternatively, the second drive unit 154 can be an air pump, allowing the airflow within the airway to directly act on one of the first clamping portion 152 and the second clamping portion 153. In yet another case, the second drive unit 154 can be a drive motor, connected to at least one of the first clamping portion 152 and the second clamping portion 153 via gears, belt drive, or screw drive. The first clamping portion 152 is slidably disposed relative to the mounting bracket 151, and the second clamping portion 153 is fixedly disposed relative to the mounting bracket 151. By driving the first clamping portion 152 with the second drive unit 154, the first clamping portion 152 and the second clamping portion 153 can be moved closer to or further away from each other. Of course, in another embodiment, both the first clamping part 152 and the second clamping part 153 are slidably disposed relative to the mounting bracket 151. The first clamping part 152 and the second clamping part 153 are linked together by means of lead screw connection or other means. The second drive unit 154 drives the first clamping part 152, and the second clamping part 153 will also move synchronously. The second drive unit 154 drives at least one of the clamping parts to slide, so that the first clamping part 152 and the second clamping part 153 move closer or further away from each other. When the first clamping part 152 and the second clamping part 153 move closer to each other, the clamping force forms a braking constraint on the cable 122. When the first clamping part 152 and the second clamping part 153 move further away from each other, the cable 122 is released to restore its degree of freedom of movement. The structure is simple and the response is fast, which can accurately realize the braking and release control of the cable 122.

[0023] In the embodiments of this application, please refer to Figure 5The cable storage reel 170 and the second drive unit 140 can be connected via a belt drive. Please refer to [link / reference]. Figure 6 The cable storage reel 170 has a cable receiving groove 171 for accommodating the cable 122. The cable storage reel 170 includes a first wall 172 and a second wall 173, which are respectively located on opposite sides of the cable receiving groove 171. A second braking element 160 is used to release or brake the first wall 172. The second braking element 160 achieves braking by acting on the first wall 172, which can disperse braking pressure, improve braking stability and reliability, and at the same time, it does not need to directly act on the cable 122 in the cable receiving groove 171, avoiding damage to the cable 122 during the braking process, thus realizing convenient braking control of the cable storage reel 170.

[0024] Preferably, the width of the cable tray 171 can be 1 to 1.5 times the diameter of the cable 122, such as 1, 1.25, or 1.5 times, and is not limited thereto. The width of the cable tray 171 should not be too narrow or too wide. If the width of the cable tray 171 is too narrow, the cable 122 cannot be wound inside the cable tray 171. If the width of the cable tray 171 is too wide, the outer cable 122 may enter the inner cable 122, and the two may become entangled. A suitable width of the cable tray 171 ensures that the cable 122 can be wound smoothly inside the cable tray 171, and that the cables 122 do not become entangled with each other.

[0025] Please see Figure 7 The surface of the first wall 172 away from the second wall 173 is provided with a clamping portion 1721, and the second braking member 160 can brake or release the clamping portion 1721. The clamping portion 1721 of the first wall 172 can be integrally formed or detachably connected. The diameter of the clamping portion 1721 is larger than that of the second wall 173. The detection device 100 also includes a protective cover 174, which covers the second wall 173 and covers the cable receiving groove 171. The protective cover 174 has an opening 1741 through which the cable 122 extends to the first driving member 130. The protective cover 174 covers the second wall 173 of the cable storage tray 170 and covers the cable receiving groove 171, allowing the cable 122 to extend to the first driving member 130 only through the pre-set opening 1741. The protective cover 174 prevents external debris from entering the cable tray 171 and contaminating the cable 122. It also restricts the movement of the cable 122, preventing it from detaching from the cable tray 171 during storage or release. This effectively prevents the cable 122 from becoming entangled outside the cable storage reel 170 or with other components, ensuring the neatness of the cable 122's storage and its safety during use. Furthermore, the first wall 172 can be located outside the protective cover 174, while the second braking component 160 can still function normally, ensuring safe operation.

[0026] Please see Figure 8The cable storage reel 170 includes a drive shaft 175 and a main body 176. The main body 176 is rotatably engaged with the drive shaft 175. A cable receiving groove 171 is formed on the main body 176. The drive shaft 175 is mounted on a base 110. The main body 176 is connected to a second driving member 140, so that the second driving member 140 drives the main body 176 to rotate around the drive shaft 175 to achieve the function of winding the cable 122. The main body 176 is provided with a rotating part, which drives the movement of the main body 176. The main body 176 of the cable storage reel 170 is rotatably engaged with the drive shaft 175. The cable receiving groove 171 is used to store the cable 122. The rotating part on the main body 176 provides a force application point for manual operation. The operator can directly drive the main body 176 to rotate around the drive shaft 175 through the rotating part, and can manually control the speed of cable 122 winding and unwinding without relying on a power drive device, thus improving operational flexibility.

[0027] In the embodiments of this application, please refer to Figure 9 The detection device 100 also includes a guide tube 181 and a first detection element 182, which can be a photoelectric sensor or a limit switch, etc. The main body 121 is movably installed inside the guide tube 181. The guide tube 181 has a through hole 1811 in its wall. The first detection element 182 is used to detect the position information of the main body 121 and is located at the through hole 1811. For example, during the process of retrieving the cable 122 and the main body 121, the main body 121 can move to the through hole 1811. The first detection element 182 monitors the position information of the main body 121 inside the guide tube 181 in real time through the through hole 1811, quickly capturing the real-time coordinates, movement trajectory, and other parameters of the main body 121. This provides data support for issuing subsequent control commands, ensuring the positioning accuracy of the main body 121 and guaranteeing the accuracy of the detection operation. The control unit is electrically connected to the first detection unit 182. When the body 121 moves to the through hole 1811, the control unit controls the first braking unit 150 to brake the cable 122 and shuts off the first driving unit 130. The first braking unit 150 brakes the cable 122, and the second driving unit 140 continues to drive the cable storage reel 170 to tighten the cable 122. This prevents the body 121 from moving out of its range and falling off.

[0028] In another implementation, please refer to [the original text]. Figure 8The detection device 100 is equipped with a second detection element 190, which can be a photoelectric sensor or a limit switch, etc. For example, the wire storage reel 170 is provided with multiple screws, which are spaced apart around the axis of the wire storage reel 170. Each screw passes through the second detection element 190, and the second detection element 190 can acquire the interval time and the number of screws passed, thereby sequentially converting the speed and number of rotations of the wire storage reel 170. The rotation information of the wire storage reel 170 includes speed and number of rotations. The second detection element 190 is used to detect the rotation information of the wire storage reel 170. A control element is electrically connected to the second detection element 190 and is used to control the second braking element 160 to brake the wire storage reel 170 and close the second driving element 140 based on the rotation information. For example, when the wire storage reel 170 rotates to a certain number of rotations threshold, the control element controls the second braking element 160 to brake the wire storage reel 170. Alternatively, with each rotation of the cable storage reel 170, the control unit controls the first braking element 150 to brake the cable 122 and closes the second driving element 140. Simultaneously, the control unit controls the second driving element 140 to continue rotating, allowing the cable harness to be pre-tensioned. When the cable storage reel 170 rotates another predetermined angle (e.g., 15° or 30°), the control unit controls the first braking element 150 to release the cable 122, and the cable storage reel 170 continues to rotate to collect the cable harness. This cycle repeats, ensuring that the cable 122 is smoothly tightened with each rotation.

[0029] In the embodiments of this application, please refer to Figure 1 as well as Figure 9 The detection device 100 also includes a cabinet 183 and a third drive component 184. A base 110 is movably mounted on the cabinet 183 and moves relative to the cabinet 183 in a direction close to or away from the workpiece to be detected (i.e., the axial direction of the guide tube 181). The third drive component 184 is mounted on the cabinet 183 and is drive-connected to the base 110. The third drive component 184 drives the base 110 to move closer to or away from the workpiece to be detected. The base 110 and the cabinet 183 form a movable fit along a first direction. The third drive component 184 is mounted on the cabinet 183 and drive-connected to the base 110. Through the power output of the third drive component 184, the base 110 and all its components can be driven to move along the first direction, realizing flexible adjustment of the distance between the base 110 and the workpiece to be detected. It can adapt to workpieces of different lengths or detection position requirements without moving the entire cabinet 183, improving the versatility and ease of operation of the device.

[0030] The third driving component 184 may include a third driving unit 1841, a first pulley 1842, a second pulley 1843, and a second transmission belt 1844. The first pulley 1842 is drivingly connected to the third driving unit 1841. The first pulley 1842 and the second pulley 1843 are rotatably mounted on the cabinet 183, and are spaced apart. The second transmission belt 1844 drives between the first pulley 1842 and the second pulley 1843. The base 110 is provided with a fixing part, which is connected to the second transmission belt 1844. The connection method can be a threaded connection or a clamping connection, etc. The third driving unit 1841 drives the first pulley 1842, so that the transmission belt drives the base 110. The base 110 is fixedly connected to the second transmission belt 1844 through the fixing part. When the transmission belt is running, it drives the base 110 to move along the cabinet 183 through the fixing part. The transmission method of the pulley and the transmission belt has high transmission efficiency and smooth operation, which can realize the uniform linear motion of the base 110, ensure the accuracy of the movement of the base 110, and thus improve the alignment accuracy of the base 110 and its body 121 with the workpiece to be tested.
