Technical Field
[0001] This utility model relates to the field of geological exploration technology, and more specifically, to a drill pipe straightness detection device for geological exploration. Background Technology
[0002] Geological exploration is an investigation and research activity that uses various means and methods to explore and detect geology, determine suitable bearing strata, determine the foundation type based on the bearing capacity of the bearing strata, and calculate foundation parameters. It is a survey and research activity that discovers industrially significant mineral deposits during mineral prospecting, provides mineral reserves and geological data needed for mine construction design to ascertain the quality and quantity of minerals and the technical conditions for mining and utilization, and investigates and studies the geological conditions such as rocks, strata, structures, minerals, hydrology, and geomorphology in a certain area. Drill rods are an indispensable component in geological exploration. When using drill rods, a straightness detection device is needed to check the straightness of the drill rods to prevent bending of the drill rods from affecting the structural strength.
[0003] However, in actual use, traditional drill pipe straightness detection devices for geological exploration have poor accuracy in detecting the straightness of drill pipes. They cannot quickly and accurately detect the straightness of drill pipes of different sizes, and are prone to errors during detection, which will directly affect the subsequent use of the drill pipes and pose safety hazards. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a drill rod straightness detection device for geological exploration, so as to solve the problems that the detection accuracy of drill rod straightness in the prior art is poor, it is impossible to quickly and accurately detect the straightness of drill rods of different sizes, and errors are very easy to occur during the detection.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a drill rod straightness detection device for geological exploration, including a base plate, a support top frame fixed on the base plate, a controller on the right side of the support top frame, a first cylinder embedded at the bottom of both sides of the inner cavity of the support top frame, a motor fixed to the piston rod of the first cylinder through a fixed cylinder, a locking seat for inserting and positioning the two ends of the drill rod fixed at the end of the output shaft of the motor, and a detection component for use with the drill rod on the support top frame.
[0006] The detection assembly includes a support plate slidably disposed within a support top frame. Multiple sets of second cylinders with piston rods fixed to the support plate are sequentially embedded in the top of the support top frame along the left-right direction. Multiple sets of reinforcing back frames are sequentially fixed to the front and back of the support plate along the left-right direction. Each set of reinforcing back frames has a detection frame inserted into it. The bottom ends of the front and rear sets of detection frames are fixed with detection plates that can fit against the top of the drill pipe. Each set of detection frames has a displacement sensor fixed to its bent end, which works in conjunction with the reinforcing back frame. Each set of detection frames has a spring wound around it, with both ends of the spring fixed to the top protruding end of the detection frame and the reinforcing back frame. Each set of detection frames has an alarm fixed to it. The displacement sensor and alarm are compatible with the controller.
[0007] The locking seats have a tapered structure on the side that is close to each other. The side of the locking seats that is close to the motor is equipped with a support side frame through an auxiliary bearing. The placement base plate has symmetrical limit slides in the front-back direction. Limit slide bars with their tops fixed to the bottom of the support side frame are slidably arranged in the limit slides.
[0008] The top of the base plate is symmetrically fixed with square columns along the front-back direction, and each set of square columns has multiple sets of positioning slots for insertion at the bottom of the testing frame along the left-right direction.
[0009] The vertical end of the testing frame is provided with a support slide, and a support slide is slidably disposed in the support slide. The top of the support slide is fixed to the top bent end of the testing frame, and the bottoms of the front and rear support slides are fixed to the two ends of the testing plate.
[0010] The number of the detection plates is at least thirteen, with a gap between adjacent groups of detection plates, and a gap between each group of detection frames and the supporting top frame.
[0011] The top of the support frame is equipped with U-shaped carriages on both sides, and the bottom of the U-shaped carriages is fixed to the support plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are: In the above solution, a first cylinder, a motor, and a locking seat are included to accommodate drill rods of different sizes and to quickly position both ends. The detection component is designed with a second cylinder to change the position of the detection plate, and a spring ensures continuous contact between the detection plate and the top of the drill rod, based on its size. A displacement sensor is designed to quickly measure the distance between the reinforcing frame and the frame when the frame is moved to a suitable position, using this distance as initial data and a preset error range. The motor drives the drill rod to rotate; if the drill rod is not bent, the rotation... During operation, the positional changes of each detection plate will be within a preset range. If the drill rod is bent, the bend will cause the entire drill rod to form a crankshaft-like structure. When the drill rod rotates, the bend will simultaneously cause the detection plate attached to it to move up or down, resulting in a significant displacement change of the displacement sensor at that point. Simultaneously, the alarm will be activated to alert the user that the drill rod is bent and to indicate the bending position of the drill rod. The entire detection process is simple and convenient, and can accurately detect the straightness of drill rods of different sizes. Each detection plate is equipped with two sets of displacement sensors, which can effectively avoid errors during detection. Attached Figure Description

[0015] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0016] Example: Please refer to Figures 1 to 5This utility model provides a technical solution: a drill rod straightness detection device for geological exploration, including a base plate 1, a support frame 2 fixed on the base plate 1, a controller on the right side of the support frame 2, and first cylinders 10 embedded in the bottom of both sides of the inner cavity of the support frame 2. A motor 3 is fixed to the piston rod of the first cylinder 10 via a fixed cylinder. A locking seat 4 for positioning the two ends of the drill rod is fixed to the end of the output shaft of the motor 3. The side of the locking seat 4 that is close to each other has a conical structure, and the shape of the inner side of the locking seat 4 is defined to accommodate the two ends. For hollow drill rods of different sizes, the locking seat 4 is rotatably mounted with a support side frame 5 on the side near the motor 3 via an auxiliary bearing. A limit slide 6 is symmetrically opened on the base plate 1 along the front and back direction. A limit slide bar with its top fixed to the bottom of the support side frame 5 is slidably installed in the limit slide 6. The design of the support side frame 5 is to provide auxiliary support for the locking seat 4, thereby improving the overall stability of the locking seat 4 and thus improving the overall stability of the drill rod to be tested, avoiding affecting the testing accuracy. The rotatable design can avoid interfering with the overall rotation of the locking seat 4. The support frame 2 is equipped with a detection assembly for use with the drill pipe. The detection assembly includes a support plate 9 slidably disposed within the support frame 2. U-shaped slides 8 are inserted into both sides of the top of the support frame 2, with the bottom ends of the U-shaped slides 8 fixed to the support plate 9. The design of the U-shaped slides 8 allows for sliding limitation of the support plate 9, improving the stability of the support plate 9 during movement and preventing tilting or displacement, thereby improving the overall detection accuracy of the drill pipe. Multiple sets of second cylinders 7 with piston rods fixed to the support plate 9 are sequentially embedded along the left-right direction on the top of the support frame 2. The support plate 9... Multiple sets of reinforcing back frames 11 are fixed sequentially along the left and right directions on the front and back sides. Each set of reinforcing back frames 11 is equipped with a detection frame 14. The bottom ends of the front and rear sets of detection frames 14 are fixed with detection plates 17 that can fit against the top of the drill pipe. The number of detection plates 17 is at least thirteen sets. There is a gap between adjacent sets of detection plates 17. There is a gap between each set of detection frames 14 and the supporting top frame 2. The limitation on the number of detection plates 17 is to limit the position of detection plates 17 and detection frames 14, so as to better improve the detection accuracy of drill pipe straightness and improve the overall applicability of the device. Each set of testing frames 14 has a displacement sensor 15 fixed at its bent end, which works in conjunction with the reinforcing back frame 11. Square columns 12 are symmetrically fixed at the top of the base plate 1 along the front-to-back direction. Each set of square columns 12 has multiple positioning slots 13 arranged sequentially along the left-to-right direction for inserting the bottom of the testing frame 14. The multiple positioning slots 13 on the square columns 12 are designed to facilitate the insertion of the testing frame 14, thereby improving the detection accuracy of the displacement sensor 15 and enabling precise detection of the drill rod's straightness. Each set of testing frames 14 is wound with a spring 16, the two ends of which are fixed to the top protruding end of the testing frame 14 and the reinforcing back frame 11. On the upper part, the vertical end of the detection frame 14 is provided with a support slide 20, and a support slide plate 19 is slidably arranged in the support slide 20. The top of the support slide plate 19 is fixed to the top bent end of the detection frame 14, and the bottoms of the front and rear support slide plates 19 are fixed to the two ends of the detection plate 17. The design of the support slide plate 19 and the support slide 20 can further support and limit the sliding of the detection frame 14, further improving the stability of the detection frame 14 when it moves, thereby further improving the measurement accuracy of the displacement sensor 15. Each set of detection frames 14 is fixed with an alarm 18. The displacement sensor 15 and the alarm 18 are adapted to the controller.
[0017] By configuring a first cylinder 10, a motor 3, and a locking seat 4, it is possible to adapt to drill rods of different sizes and quickly position them. If the drill rod is not bent, after positioning, the drill rod and the output shaft of the motor 3 can be aligned on the same transverse axis. The design of the detection component utilizes a second cylinder 7, in conjunction with a spring 16, to ensure continuous contact between the detection plate 17 and the top of the drill rod according to its size. Simultaneously, the displacement sensor 15 can quickly measure the distance between the plate and the reinforcing frame 11, and this distance value is used as initial data, with a preset error range. Simultaneously, the motor 3 can drive the drill rod to rotate. When the drill rod bends, the bending point will synchronously drive the detection plate 17 attached to it to move up or down, causing a large displacement change in the displacement sensor 15 at that point. At the same time, the alarm 18 will be activated to alert the user that the drill rod is bent and can also indicate the bending position of the drill rod. The whole detection process is simple and convenient, and can accurately detect the straightness of drill rods of different sizes. Each detection plate 17 is equipped with two sets of displacement sensors 15 as standard, which can effectively avoid errors during detection.
[0018] The working process of this utility model is as follows: The user places the drill rod above the base plate 1 and activates the first cylinder 10 via the controller. This drives the locking seat 4 to move inward and insert into both ends of the drill rod. The drill rod is hollow at both ends, allowing the locking seat 4 to be stably inserted. Since the inner side of the locking seat 4 has a tapered structure, it can be pressed and positioned according to the size of the drill rod. If the drill rod is not bent, the output shaft of the motor 3 and the drill rod are on the same transverse axis. At this time, the user activates the second cylinder 7 via the controller. The second cylinder 7 drives the support plate 9 and the reinforcing back frame 11 to move downwards synchronously. The detection plate 17 will initially contact the top of the drill rod. As the support plate 9 continues to move downwards, the detection plate 17 drives the detection frame 14 to move upwards synchronously, stretching the spring 16. The elastic rebound of the spring 16 provides a continuous pushing force to the detection frame 14, ensuring continuous contact between the detection plate 17 and the top of the drill rod until the reinforcing back frame 1... The bottom end of 1 is inserted into the positioning socket 13. At this time, the displacement sensor 15 can detect the distance value between it and the reinforcement back frame 11, and store this distance value as the initial data in the controller and preset the error range. Then, the user turns on the motor 3 through the controller. At this time, the motor 3 can drive the drill rod to rotate slowly and uniformly. If the drill rod is not bent, the change value of the position of each set of detection plates 17 will be within the preset range when the drill rod rotates. If the drill rod is bent, the bend will make the drill rod form a crankshaft-like structure. When the drill rod rotates, the bend will synchronously drive the detection plate 17 attached to it to move up or down, and cause the displacement sensor 15 at that point to undergo a large displacement change. The displacement value exceeds the preset range. At this time, the controller receives the displacement change signal and synchronously activates the alarm 18 at the corresponding position to warn the user that the drill rod is bent and can also simultaneously indicate the bending position of the drill rod.
