A cement pole wall thickness uniformity detection device

Abstract

This invention relates to the field of concrete component quality testing technology, and discloses a device for detecting the uniformity of wall thickness of cement utility poles. The device includes a semi-circular plate with a fixed plate fixedly installed at its bottom. The inner wall of the fixed plate is provided with fixing bolts, and a sliding block is slidably connected to the inner wall of the semi-circular plate. A first limiting groove and a second limiting groove are respectively formed on the inner wall of the semi-circular plate, and an internal gear ring is fixedly installed on the inner wall of the semi-circular plate. By starting a motor, the motor drives a drive shaft to rotate, which in turn drives an external gear to rotate. The gear meshes with the internal gear ring and moves circumferentially along the inner wall of the internal gear ring. This causes the gear to move the sliding block and the upper structure, which in turn causes the support shell to move the main body of the internal testing device. This allows the detection probe outside the main body of the testing device to move along the outer wall of the utility pole, thus eliminating the need for manual equipment movement.

Description

Technical Field

[0001] This invention relates to the field of concrete component quality testing technology, specifically to a device for testing the uniformity of wall thickness of cement utility poles. Background Technology

[0002] Cement power poles are core supporting components in fields such as power transmission, communication infrastructure, and municipal lighting. They are widely used in urban and rural power grid construction and the laying of power transmission lines in the field. Their structural quality directly determines the operational stability of power lines and public safety.

[0003] The uniformity of the wall thickness of utility poles is a core indicator for measuring their manufacturing process quality and structural load-bearing capacity. Defects such as uneven wall thickness and local thinning will significantly reduce the poles' resistance to wind pressure and bending. During long-term service, they are prone to safety hazards such as cracking, breakage, and overturning, which seriously threaten the safety of power grid transmission.

[0004] According to the relevant national standard GB / T4623-2025 for concrete poles, the uniformity of the wall thickness of the poles must be comprehensively and accurately tested during the production, operation and maintenance stages to prevent unqualified products from being put into use.

[0005] Currently, the uniformity of cement pole wall thickness is mostly tested manually using handheld testing instruments at single points. The supporting testing equipment has a simple structure and many inherent defects in actual testing operations.

[0006] Existing testing equipment lacks a dedicated external fixing structure, relying entirely on manual hand-holding and fitting of the instrument during the testing process. When testing high-altitude, long-distance utility poles, the stability of manual fixing is extremely poor, easily leading to instrument displacement and probe misalignment. This not only results in high labor intensity and low work efficiency but also easily causes data distortion due to human error, failing to accurately reflect the overall uniformity of the utility pole's wall thickness. Furthermore, existing testing instruments and auxiliary supports are mostly integrated fixing structures, making disassembly and assembly difficult.

[0007] In scenarios involving batch inspection of utility poles, equipment transportation, and instrument maintenance and calibration, the inability to quickly disassemble and replace testing instruments, coupled with insufficient equipment versatility and portability, significantly reduces the flexibility of on-site testing operations and makes it difficult to adapt to the rapid testing needs of utility poles of different specifications.

[0008] In addition, conventional testing equipment does not have an adaptive clamping compensation structure, and cannot continuously provide a fitting thrust to the testing probe during the testing process.

[0009] Due to the slight unevenness and curvature deviations on the outer wall of cement utility poles, it is difficult to ensure a tight fit between the testing head and the pole surface throughout the entire process during manual handheld inspection. This can easily lead to problems such as probe suspension and insufficient coupling, resulting in large deviations in wall thickness measurement data and numerous blind spots. Consequently, it is impossible to achieve comprehensive and accurate detection of the uniformity of utility pole wall thickness, which fails to meet the high-precision and high-efficiency quality inspection standards of modern power infrastructure construction. In summary, current cement pole wall thickness uniformity testing equipment generally suffers from technical problems such as poor fixation stability, cumbersome instrument disassembly and assembly, and probes that cannot adaptively fit the pole body. This results in low testing accuracy, low work efficiency, and poor versatility, making it unable to meet the needs of large-scale and standardized pole quality testing operations.

[0010] Therefore, there is an urgent need to design a cement pole wall thickness uniformity detection device that can be externally fixed, has quick instrument disassembly and assembly, and adaptive probe fitting, in order to solve many defects in the existing technology. Summary of the Invention

[0011] To address the shortcomings of existing technologies, this invention provides a device for detecting the uniformity of wall thickness of cement utility poles, which has the advantages of being easy to use and saving manpower, and solves the problems mentioned in the background art.

[0012] To achieve the above-mentioned objectives, the present invention provides the following technical solution: A device for detecting the uniformity of wall thickness of cement utility poles includes a semicircular plate. A fixing plate is fixedly installed at the bottom of the semicircular plate. Fixing bolts are provided on the inner wall of the fixing plate. A sliding block is slidably connected to the inner wall of the semicircular plate. A first limiting groove and a second limiting groove are respectively formed on the inner wall of the semicircular plate. An internal gear ring is fixedly installed on the inner wall of the semicircular plate. A motor and a support block are fixedly installed on the top of the sliding block. A drive shaft is fixedly installed on the output shaft of the motor. A gear is fixedly installed on the outer wall of the drive shaft. A first limiting strip and a second limiting strip are fixedly installed on both sides of the outer wall of the sliding block. The top of the support block slides... The device is connected to a support shell, the inner wall of which is provided with the main body of the detection device. An extension shell is fixedly installed on the top of the support shell, and an extension plate is fixedly installed on the bottom of the support shell. A limit post is fixedly installed on the inner wall of the support block, and a spring is provided on the outer wall of the limit post. A sliding plate is slidably connected to the inner wall of the extension shell, and a limit rod is fixedly installed on the inner wall of the extension shell. A threaded screw is rotatably connected to the inner wall of the extension shell, and a sliding plate is slidably connected to the inner wall of the extension shell. A pin is fixedly installed at the bottom of the sliding plate. A locking groove is opened on the top of the main body of the detection device, and a screw nut is fixedly installed on the inner wall of the sliding plate.

[0013] To better achieve the above-mentioned objectives, the present invention adopts a further technical solution: the outer wall of the main body of the detection device is provided with a display module and a control module respectively, and a detection probe is fixedly installed on the outer wall of the main body of the detection device, located on the side of the main body of the detection device away from the display module and the control module, and the detection probe penetrates the support shell.

[0014] To better achieve the above-mentioned objectives, the present invention adopts a further technical solution: the gear is located on the inner wall of the internal gear ring, and the gear meshes with the internal gear ring.

[0015] To better achieve the above-mentioned objectives, the present invention adopts a further technical solution: the first limiting strip and the second limiting strip are respectively located on both sides of the sliding block, and the first limiting strip and the second limiting strip are respectively located on the inner walls of the first limiting groove and the second limiting groove.

[0016] To better achieve the above-mentioned objectives, the present invention adopts a further technical solution: the limiting post penetrates the extension plate, and the two ends of the spring are respectively attached to the outer wall of the extension plate and the inner wall of the support block.

[0017] To better achieve the above-mentioned objectives, the present invention adopts a further technical solution: the number of the limiting rods is two, and the two limiting rods are symmetrically arranged, with the two limiting rods penetrating the sliding plate.

[0018] To better achieve the above-mentioned objectives, the present invention adopts a further technical solution: the lead screw nut is sleeved on the outer wall of the threaded lead screw, and the lead screw nut and the threaded lead screw are threadedly connected.

[0019] To better achieve the above-mentioned objectives, the present invention adopts a further technical solution: the diameter of the insert is adapted to the inner wall diameter of the lock groove, and the insert is located above the lock groove.

[0020] Compared with the prior art, the present invention has the following beneficial effects: 1. The cement pole wall thickness uniformity detection device, by starting the motor, causes the drive shaft to rotate, which in turn causes the external gear to rotate. The gear moves circumferentially along the inner wall of the internal gear ring through meshing with the gear, which in turn causes the sliding block and the upper structure to move. This causes the support shell to move the main body of the detection device inside, and the detection probe outside the main body of the detection device to move along the outer wall of the pole, thus eliminating the need for manual equipment movement.

[0021] 2. This cement pole wall thickness uniformity testing device involves placing two semi-circular plates, a fixed plate, a first limiting groove, an internal toothed ring, and a second limiting groove on both sides of the pole. The two fixed plates are then attached together and secured with bolts, fixing them to the outside of the pole. The main body of the testing device is then placed inside the support shell. Rotating the threaded screw causes it to move through its threaded connection with the screw nut, which in turn moves the sliding plate. This, in turn, moves the bottom insertion post, causing it to enter the inner wall of the locking groove, thus fixing the main body of the testing device to the inner wall of the support shell. The spring's elasticity pushes an extension plate, which in turn moves the support shell and the main body of the testing device toward the pole, bringing the external testing probe of the device into contact with the outer wall of the pole.

[0022] 3. The cement pole wall thickness uniformity detection device uses the elasticity of the spring to push the extension plate, causing the extension plate to move towards the pole. This movement of the extension plate causes the support shell to exert pressure towards the pole, which in turn causes the detection device body inside the support shell to move towards the pole, ensuring that the detection probe is always in contact with the outer surface of the pole.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1 - Figure 6 A device for detecting the uniformity of wall thickness of cement utility poles includes a semicircular plate 1, a fixing plate 2 fixedly installed at the bottom of the semicircular plate 1, fixing bolts 3 provided on the inner wall of the fixing plate 2, a sliding block 4 slidably connected to the inner wall of the semicircular plate 1, a first limiting groove 5 and a second limiting groove 19 respectively opened on the inner wall of the semicircular plate 1, an internal gear ring 7 fixedly installed on the inner wall of the semicircular plate 1, a motor 9 and a support block 10 fixedly installed on the top of the sliding block 4, a drive shaft 6 fixedly installed on the output shaft of the motor 9, and a gear 11 fixedly installed on the outer wall of the drive shaft 6. A first limiting strip 8 and a second limiting strip 20 are fixedly installed on both sides of the outer wall of the moving block 4. A supporting shell 12 is slidably connected to the top of the supporting block 10. A detection device body 13 is provided on the inner wall of the supporting shell 12. An extension shell 14 is fixedly installed on the top of the supporting shell 12. An extension plate 15 is fixedly installed on the bottom of the supporting shell 12. A limiting post 16 is fixedly installed on the inner wall of the supporting block 10. A spring 17 is provided on the outer wall of the limiting post 16. A sliding plate 21 is slidably connected to the inner wall of the extension shell 14. A limiting rod 22 is fixedly installed on the inner wall of the extension shell 14. The inner wall of the extension shell 14 is rotatably connected to a threaded screw 23, and the inner wall of the extension shell 14 is slidably connected to a sliding plate 21. A pin 24 is fixedly installed at the bottom of the sliding plate 21. A locking groove 25 is opened at the top of the main body 13 of the detection device, and a screw nut 28 is fixedly installed on the inner wall of the sliding plate 21. There are two semicircular plates 1, fixed plates 2, first limiting grooves 5, internal toothed rings 7 and second limiting grooves 19, and the two semicircular plates 1, fixed plates 2, first limiting grooves 5, internal toothed rings 7 and second limiting grooves 19 are fixed by fixing bolts 3. This design ensures that the two semicircular plates 1, the fixed plate 2, the first limiting groove 5, the internal toothed ring 7, and the second limiting groove 19 are fitted together in a ring shape, thus better fitting the outer surface of the utility pole. The two first limiting grooves 5 and the second limiting groove 19 form a complete ring-shaped closed loop after combination, thereby providing a complete movement path for the first limiting strip 8 and the second limiting strip 20, and enabling the sliding block 4 to form a complete movement path. At the same time, the fitting of the two internal toothed rings 7 can form a complete toothed ring, thereby providing a complete movement path for the gear 11.

[0028] The outer wall of the main body 13 of the detection device is provided with a display module 26 and a control module 27. A detection probe 18 is fixedly installed on the outer wall of the main body 13, located on the side of the main body 13 away from the display module 26 and the control module 27. The detection probe 18 penetrates the support shell 12, so that there are no objects obstructing the external surface of the detection probe 18, allowing the detection probe 18 to contact the surface of the utility pole. Through the contact between the detection probe 18 and the surface of the utility pole, the main body 13 of the detection device can monitor the wall thickness of the utility pole through the detection probe 18. At the same time, the internal electrical structure of the main body 13 of the detection device can be controlled through the control module 27, and the detection results are presented through the display module 26, thus providing a platform for operation and observation for the staff.

[0029] Gear 11 is located on the inner wall of the internal gear ring 7 and meshes with the internal gear ring 7. When the motor 9 is started, the motor 9 drives the drive shaft 6 to rotate, which in turn drives the external gear 11 to rotate. This causes the gear 11 to move circumferentially along the inner wall of the internal gear ring 7 through meshing with it. This causes the gear 11 to drive the sliding block 4 and the support shell 12, the detection device body 13, and the extension shell 14 above it.

[0030] The first limiting strip 8 and the second limiting strip 20 are located on both sides of the sliding block 4, and the first limiting strip 8 and the second limiting strip 20 are located on the inner walls of the first limiting groove 5 and the second limiting groove 19, respectively. Because the first limiting strip 8 and the second limiting strip 20 are located inside the first limiting groove 5 and the second limiting groove 19, the first limiting strip 8 and the second limiting strip 20 can only move within the inner walls of the first limiting groove 5 and the second limiting groove 19 when they move. This limits the first limiting strip 8 and the second limiting strip 20, and at the same time limits the sliding block 4, so that the sliding block 4 will not deviate from the predetermined trajectory when it moves, thereby ensuring that the detection device body 13 above the sliding block 4 will not deviate.

[0031] The limiting post 16 penetrates the extension plate 15, and the two ends of the spring 17 are respectively attached to the outer wall of the extension plate 15 and the inner wall of the support block 10. By penetrating the extension plate 15 through the limiting post 16, the extension plate 15 can only move linearly on the outer wall of the limiting post 16 when it moves, thus limiting the extension plate 15. At the same time, the elasticity of the spring 17 pushes the extension plate 15, causing the extension plate 15 to move towards the utility pole, which in turn causes the extension plate 15 to drive the support shell 12 to move, causing the support shell 12 to exert pressure towards the utility pole.

[0032] There are two limiting rods 22, and the two limiting rods 22 are symmetrically arranged. The two limiting rods 22 penetrate the sliding plate 21. By the limiting rods 22 penetrating the sliding plate 21, the sliding plate 21 can only move axially on the outer wall of the two limiting rods 22 when it moves. This limits the sliding plate 21 when it moves, so that the sliding plate 21 and the bottom insert 24 will not tilt when they move.

[0033] The lead screw nut 28 is sleeved on the outer wall of the threaded lead screw 23, and the lead screw nut 28 and the threaded lead screw 23 are threadedly connected. By rotating the threaded lead screw 23, the threaded lead screw 23 drives the lead screw nut 28 to move inside the extension shell 14 through the threaded connection with the lead screw nut 28, which in turn drives the sliding plate 21 to move, and the sliding plate 21 drives the bottom insert 24 to move.

[0034] The diameter of the insertion post 24 is matched with the inner wall diameter of the locking groove 25, and the insertion post 24 is located above the locking groove 25. The sliding plate 21 moves downward, causing the sliding plate 21 to drive the insertion post 24 downward, so that the insertion post 24 enters the inner wall of the locking groove 25. At this time, the position of the locking groove 25 is fixed by the insertion post 24, thereby fixing the detection device body 13, and thus fixing the detection device body 13 to the inner wall of the support shell 12.

[0035] In use, the two semicircular plates 1, the fixing plate 2, the first limiting groove 5, the internal toothed ring 7, and the second limiting groove 19 are placed on both sides of the utility pole. At this time, the two fixing plates 2 are in contact and then fixed with fixing bolts 3, so that the two semicircular plates 1, the fixing plate 2, the first limiting groove 5, the internal toothed ring 7, and the second limiting groove 19 are fixed to the outside of the utility pole. Then, the main body 13 of the detection device is placed inside the support shell 12. Then, by rotating the threaded screw 23, the threaded screw 23 drives the screw nut 28 to move through the threaded connection between the threaded screw 23 and the screw nut 28. This causes the screw nut 28 to drive the sliding plate 21 to move, which in turn causes the sliding plate 21 to drive the bottom insertion post 24 to move, so that the insertion post 24 enters the inner wall of the locking groove 25, thus fixing the main body 13 of the detection device. This fixes the main body 13 of the detection device to the inner wall of the support shell 12. At this time, the elasticity of the spring 17 causes the spring 17 to... The extension plate 15 is pushed, which in turn causes the support shell 12 and the detection device body 13 to move towards the utility pole, so that the detection probe 18 on the outside of the detection device body 13 is in contact with the outer wall of the utility pole. At this time, the motor 9 is started, which causes the drive shaft 6 to rotate, which in turn causes the drive shaft 6 to rotate the external gear 11. The gear 11 moves circumferentially along the inner wall of the inner gear ring 7 through meshing with it, which in turn causes the sliding block 4 and the structure above it to move. This causes the support shell 12 to move the internal detection device body 13, and the detection probe 18 on the outside of the detection device body 13 to move along the outer wall of the utility pole. At the same time, the spring 17 pushes the detection probe 18 to always be in contact with the utility pole, so that the detection device body 13 can detect the wall thickness of the utility pole through the detection probe 18. After the detection is completed, the device is disassembled to facilitate the carrying and transportation of the equipment.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
