Description

Technical Field

[0001] The present invention relates to the technical field of sonic logging tube threading devices, and particularly to an auxiliary threading device for sonic logging tubes of a steel reinforcement cage. Background Art

[0002] The sonic logging tube of the steel reinforcement cage is a key component for concrete quality detection in pile foundation projects. It forms a sound wave transmission channel by being embedded in the steel reinforcement cage. It is made of seamless steel pipe, with high strength and corrosion resistance, and forms a continuous pipeline through screw or socket connection. During construction, it needs to be tied and fixed synchronously with the steel reinforcement cage to ensure verticality and tightness. During detection, the probe emits sound waves along the tube, and by analyzing the propagation time and energy attenuation, the integrity of the pile body can be accurately judged, cracks, cavities and other defects can be identified, providing a reliable basis for the quality acceptance of the pile foundation.

[0003] Among them, the requirements for the installation quantity of the sonic logging tubes of the steel reinforcement cage are mainly determined according to the diameter of the pile foundation. For pile foundations with a diameter less than 1 meter, 2 sonic logging tubes are arranged in parallel in the pile steel reinforcement cage. For pile foundations with a diameter greater than 1 meter and less than 2.5 meters, 3 sonic logging tubes are arranged in an equilateral triangle shape in the pile steel reinforcement cage. For pile foundations with a diameter greater than 2.5 meters, 4 sonic logging tubes are evenly arranged in a square shape in the pile steel reinforcement cage.

[0004] Referring to a rotary drilling pile sonic logging tube installation guiding device disclosed in the patent application with the publication number of CN208167832U, the operator tightens the connecting rod at the bottom end of the processed sonic logging tube, and places the guiding cage inside the steel reinforcement cage. The worker lifts the other end of the sonic logging tube and pushes the sonic logging tube through the guiding cage towards the bottom end of the steel reinforcement cage. After the sonic logging tube is installed in place, the connecting rod is loosened and the guiding device is taken out together. By guiding the installation of the sonic logging tube through the guiding cage, the resistance of the sonic logging tube to penetrate is reduced, the installation efficiency is improved while ensuring the assembly quality, and the labor intensity is effectively reduced.

[0005] The above-mentioned installation of the sonic logging tube in the prior art has the following defects in actual use: During the construction of the above patent, the sonic logging tube is dragged forward in the steel reinforcement cage. During the relative penetration process of the sonic logging tube and the steel reinforcement cage, friction and collision will inevitably occur, and the collision is extremely likely to cause deformation and dislocation of the sonic logging tube joint, and even deformation of the tube wall, which will reduce the tightness and connection stability of the sonic logging tube, and further have an adverse impact on the subsequent ultrasonic detection work. Secondly, for a steel reinforcement cage that needs to install multiple sonic logging tubes, after the sonic logging tube is dragged to the designated position, it is also necessary to manually distribute multiple sonic logging tubes evenly at different positions inside the steel reinforcement cage and tie them with iron wire. Since the internal space of the steel reinforcement cage is narrow and the sonic logging tube is long, it is difficult to move the sonic logging tube and fix it to the steel reinforcement cage. The installation process of this method is time-consuming and highly dependent on human resources, resulting in a significant increase in project costs.

[0006] Therefore, the present invention proposes an auxiliary threading device for the acoustic detection tubes of the steel reinforcement cage to solve the above problems. Summary of the Invention

[0007] In view of the deficiencies of the prior art, the present invention provides an auxiliary threading device for the acoustic detection tubes of the steel reinforcement cage, which solves the problems that when the acoustic detection tubes are threaded relative to the steel reinforcement cage, friction and collision are inevitable, and the collision is likely to cause deformation of the joints and pipe walls of the acoustic detection tubes, reducing their sealing performance and connection stability, affecting subsequent ultrasonic detection. In addition, for the steel reinforcement cage with multiple acoustic detection tubes installed, after the acoustic detection tubes are in place, it is necessary to manually distribute the multiple acoustic detection tubes evenly at different positions inside the steel reinforcement cage and tie them with iron wires. However, the internal space of the steel reinforcement cage is limited, and the acoustic detection tubes are long, making it difficult to move and fix them. This installation method takes a long time and highly relies on manpower, resulting in a significant increase in project costs.

[0008] To achieve the above objectives, the present invention is realized through the following technical solutions: An auxiliary threading device for the acoustic detection tubes of the steel reinforcement cage includes a steel reinforcement cage assembly and an acoustic detection tube assembly, and further includes: A hanger mechanism, which is arranged on the ground and is used to provide support and traction power for the threading process of the acoustic detection tube assembly; A steel reinforcement cage positioning mechanism, which is arranged at the bottom of the hanger mechanism and is used to fix the position of the steel reinforcement cage assembly before threading the acoustic detection tube assembly to prevent the steel reinforcement cage assembly from shaking, and can be flexibly adjusted according to different size specifications of the steel reinforcement cage assembly to limit the positions of different size specifications of the steel reinforcement cage assembly; A steel reinforcement cage guiding mechanism, which is arranged on one side of the steel reinforcement cage positioning mechanism and is used to pre-position the position of the acoustic detection tube assembly relative to the steel reinforcement cage assembly to limit the parallelism and specific installation position of the acoustic detection tube assembly relative to the steel reinforcement cage assembly, and ensure that the acoustic detection tube assembly moves along a preset trajectory during the subsequent threading process; The steel reinforcement cage guiding mechanism further includes a traction component that plays a guiding and traction role.

The steel wire rope passes through the bottom of the pulley and a lifting belt is fixedly arranged.

[0013] Furthermore, the steel reinforcement cage positioning mechanism includes a cylinder body. A plurality of square through grooves are evenly formed on the outer wall of the cylinder body. An arc-shaped block is fixedly arranged on the inner wall of each square through groove. A limiting component is slidably sleeved on the outer wall of the arc-shaped block.

[0018] The present invention provides an auxiliary threading device for a steel cage acoustic pipe. Compared with the prior art, it has the following beneficial effects: 1. An auxiliary threading device for a steel cage acoustic pipe. By setting a steel cage positioning component, before threading the acoustic pipe component, the axial position and the position relative to the hanging frame mechanism of the steel cage component can be locked first, so as to prevent the steel cage component from shaking and shifting during the threading of the acoustic pipe component. Moreover, the steel cage positioning component can flexibly adjust the length of the limiting component according to the steel cage components with different inner diameters, so that the radius of the circle formed by the ends of the plurality of limiting components is adapted to the inner diameter of the steel cage component to be processed, thereby improving the practicability of the steel bar component.

[0019] 2. An auxiliary threading device for a steel cage acoustic pipe. By setting a steel cage guiding component, before installing the acoustic pipe component, the acoustic pipe components to be installed can be connected first by using a plurality of pre-support components, so that the relative positions of the plurality of acoustic pipe components can be determined outside the steel cage component. Therefore, after the acoustic pipe component enters the steel cage component, there is no need for manual adjustment of the installation position again. Compared with adjusting the position of the acoustic pipe component inside the steel cage, the operating space outside the steel cage component is larger, which greatly reduces the operating speed and difficulty, and greatly improves the threading efficiency and operating safety of the acoustic pipe; secondly, after the acoustic pipe component is fixed in position by the steel cage guiding component, when the steel cage guiding component enters the steel cage component, both the traction component and the pre-support component can slide along the outer wall of the main reinforcement bar, so that the acoustic pipe component will not rub or collide with the inner wall of the steel cage during the movement process, thereby avoiding the situation that the acoustic pipe component is deformed or misaligned, and ensuring the accuracy of the subsequent ultrasonic detection result.

[0020] 3. A device for assisting in threading a sonic logging tube through a steel reinforcement cage. Both the traction assembly and the pre - support assembly can flexibly adjust the positions of their rubber guide wheels and arc - shaped clamping sleeves respectively according to the inner diameter of the steel reinforcement cage assembly, so that the traction assembly and the pre - support assembly can be applied to the threading work of steel reinforcement cage assemblies with various size specifications. Secondly, the upper clamp, the lower clamp and the arc - shaped clamping sleeve in the pre - support assembly can be flexibly replaced respectively according to the outer diameter of the sonic logging tube body and the outer diameter of the main reinforcement bars, thus further expanding the applicable range of the pre - support assembly.

[0021] 4. A device for assisting in threading a sonic logging tube through a steel reinforcement cage. By setting up a hanging frame mechanism, compared with the prior art, the integrated and movable operation system of the present invention optimizes the traditional method of using a crane to assist manual pipe threading into an efficient small - scale electric winch pipe threading method. Combined with a specially made all - directional movable lifting frame, it shows excellent mobility and can adapt to changing construction environments. Through the mobile operation mode, rapid response and precise positioning are achieved, the threading process is simplified, the labor cost is greatly reduced, the construction efficiency and safety are significantly improved, and it can be recycled repeatedly after one - time threading forming, eliminating the need for each repeated installation and disassembly process. It can effectively save the time, cost, labor and materials required for construction, and greatly speed up the construction progress. In other projects such as diaphragm wall construction, when it comes to the threading operation of the sonic logging tube inside the steel reinforcement cage, this auxiliary device can also be used for operation.

[0025] The present invention provides four technical solutions: a steel cage sonic logging tube auxiliary threading device, specifically including the following embodiments: As Figure 1 , Figure 4 , Figures 8 - 9 and Figure 14 , which shows the first implementation manner: a steel cage sonic logging tube auxiliary threading device, including a steel cage assembly 1 and a sonic logging tube assembly 5, and further including: The hanger mechanism 2 is arranged on the ground and is used to provide support and traction power for the threading process of the acoustic pipe assembly 5; The steel cage positioning mechanism 3 is arranged at the bottom of the hanger mechanism 2 and is used to fix the position of the steel cage assembly 1 before threading the acoustic pipe assembly 5, so as to prevent the steel cage assembly 1 from shaking, and can be flexibly adjusted according to the steel cage assemblies 1 of different size specifications to limit the positions of the steel cage assemblies 1 of different size specifications; The steel cage guiding mechanism 4 is arranged on one side of the steel cage positioning mechanism 3 and is used to pre-position the position of the acoustic pipe assembly 5 relative to the steel cage assembly 1, so as to limit the parallelism and specific installation position of the acoustic pipe assembly 5 relative to the steel cage assembly 1, and ensure that the acoustic pipe assembly 5 moves along a preset trajectory during the subsequent threading process; In the embodiment of the present invention, the steel cage guiding mechanism 4 further includes a traction assembly 41 that plays a guiding and traction role. A pre-positioning assembly 42 for pre-assembling one or more acoustic pipe assemblies 5 is arranged on one side of the traction assembly 41. And after the pre-positioning assembly 42 completes the guiding work, it directly serves as a fastener to lock the acoustic pipe assembly 5 and the steel cage assembly 1 to each other. The pre-positioning assembly 42 and the traction assembly 41 are connected by a connecting rod 43.

[0026] In the embodiment of the present invention, the acoustic pipe assembly 5 includes an acoustic pipe body 51. A tapered sleeve 52 is detachably sleeved at one end of the acoustic pipe body 51. The tapered sleeve 52 and the acoustic pipe body 51 are locked by bolts. The tapered sleeve 52 includes a cylindrical hollow pipe.

A plurality of stirrups 12 are equidistantly sleeved on the outer walls of the plurality of main reinforcements 11. The plurality of stirrups 12 and each main reinforcement 11 are fixed by welding.

[0028] In the embodiment of the present invention, the hanger mechanism 2 includes a lifting frame 21 and universal wheels fixedly arranged at the four corners of the bottom of the lifting frame 21. A support plate 22 is fixedly arranged on the outer wall of the lifting frame 21. A pulley 23 is rotatably arranged at the middle position of the top of the support plate 22 through a pulley frame. An electric hoist 24 is fixedly arranged on the side wall of the lifting frame 21 and above the pulley 23. A steel wire rope 25 is wound around the output end of the electric hoist 24. The steel wire rope 25 passes through the bottom of the pulley 23 and a lifting belt 26 is fixedly arranged. The lifting belt 26 is sleeved on the traction hook 413 and can traction the bearing plate 411 to move. The universal wheels have a manual locking function to ensure that they will not move during work.

[0029] As Figure 2 , Figure 5The second implementation manner is shown. The difference from the first implementation manner is that the traction assembly 41 includes a bearing disk 411. At the central positions on the outer walls on both sides of the bearing disk 411, a first threaded sleeve 412 and a traction hook 413 are respectively and fixedly arranged. On the outer wall of the bearing disk 411 and symmetrically on both sides of the first threaded sleeve 412, two cross chutes 414 are provided. A slider 416 is slidably arranged inside each cross chute 414. One end of the slider 416 away from the bearing disk 411 is rotatably provided with a rubber guide wheel 417 through a wheel carrier. On the outer wall of the bearing disk 411, a second scale thread groove 415 for marking the position of the slider 416 is further provided. The slider 416 and the cross chute 414 are locked through a fastening bolt. One end of the connecting rod 43 is detachably arranged inside the first threaded sleeve 412 through a bolt, and the other end of the connecting rod 43 is threadedly connected inside an adjacent second threaded sleeve 4212; As Figure 3 , Figure 6 , Figure 7 The third implementation manner is shown. The difference from the second implementation manner is that the pre-positioning assembly 42 includes pre-support assemblies 421 and connecting rods 422 that are alternately connected to each other in sequence at the head and tail. The pre-support assemblies 421 and the connecting rods 422 are detachably connected through threads.

[0030] In an embodiment of the present invention, the pre-support assembly 421 includes a mounting disk 4211 and second threaded sleeves 4212 fixedly arranged at the central positions on both outer wall sides of the mounting disk 4211. A plurality of first marking grooves 4213 and second marking grooves 4214 are evenly formed on one outer wall side of the mounting disk 4211. One guiding arm assembly is detachably arranged on both outer wall sides of the mounting disk 4211. The guiding arm assembly includes a support arm unit 4215 detachably arranged on the outer wall of the mounting disk 4211. Upper and lower clamps 4216 and 4217 are respectively detachably arranged on the upper and lower sides of the end of the support arm unit 4215 far from the mounting disk 4211. An arc-shaped clamping sleeve 4218 is detachably arranged on the outer walls of the upper and lower clamps 4216 and 4217 through bolts. A sealing plate 4219 is detachably arranged on the side walls of the two arc-shaped clamping sleeves 4218 together. A connecting rod 422 is threadedly connected inside the second threaded sleeve 4212. The circular contour formed by the upper and lower clamps 4216 and 4217 is adapted to the outer diameter of the acoustic pipe body 51 to be installed. The circular contour formed by the sealing plate 4219 and the two arc-shaped clamping sleeves 4218 is adapted to the outer diameter of the main reinforcement 11. The upper and lower clamps 4216 and 4217 can be correspondingly replaced according to the size of the acoustic pipe body 51 to be installed, while the sealing plate 4219 and the two arc-shaped clamping sleeves 4218 can be replaced according to the outer diameter size of the main reinforcement 11. The two arc-shaped clamping sleeves 4218 are slidably arranged on the outer wall of the main reinforcement 11 at the same time. The length formed by the mounting disk 4211 and the two guiding arm assemblies is just adapted to the inner diameter of the steel cage assembly 1, that is, the inner walls of the arc-shaped clamping sleeves 4218 on both sides can closely adhere to the inner wall of the main reinforcement 11 and can slide relatively. There are four first marking grooves 4213, which are distributed in an annular array manner and are used when four acoustic pipe bodies 51 need to be installed. In this case, the four support arm units 4215 can be installed according to the positions of the first marking grooves 4213. There are three second marking grooves 4214, which are distributed in an annular array manner. The three support arm units 4215 can be installed according to the positions of the first marking grooves 4213. When installing one acoustic pipe body 51, one of the first marking grooves 4213 or one of the second marking grooves 4214 can be selected as a reference point. When installing two acoustic pipe bodies 51, two symmetrically arranged first marking grooves 4213 can be selected as reference points for use.

[0031] In an embodiment of the present invention, the support arm unit 4215 includes an extension arm a1 and a base arm a2 disposed on one side of the extension arm a1. The interior of the extension arm a1 is a hollow structure. One end of the base arm a2 close to the extension arm a1 is fixedly provided with an extension arm a3. The extension arm a3 is slidably disposed inside the extension arm a1. Third scale grooves a4 for marking the length extending out of the extension arm a1 are evenly formed on the outer wall of the extension arm a3. After the extension arm a3 is completely retracted into the extension arm a1, the total length formed by the extension arm a1 and the base arm a2 is a known original length. According to the length of the extension arm a3 exposed, this part of the length can be added to the original length to obtain the current length. The positions of the extension arm a1 and the extension arm a3 are locked by fastening bolts.

[0032] As Figures 10 - 13 The fourth embodiment is shown. The difference from the third embodiment is that: the steel cage positioning mechanism 3 includes a cylinder 31. A plurality of square through grooves 32 are evenly formed on the outer wall of the cylinder 31. An arc block 33 is fixedly provided on the inner wall of each square through groove 32. A limiting component 34 is slidably sleeved on the outer wall of the arc block 33. And a first scale groove 35 for marking the position of the first scale groove 35 is also formed on the side wall of the arc block 33. A conical column 36 for simultaneously driving a plurality of limiting components 34 to move away from or close to each other is slidably disposed inside the cylinder 31. A servo motor 37 is fixedly provided on the outer wall of the cylinder 31. A lead screw 38 is also fixedly provided on the output shaft of the servo motor 37. The lead screw 38 is connected to the inside of the conical column 36 in a threaded manner. A threaded hole adapted to the lead screw 38 is formed inside the conical column 36. The lead screw 38 is threadedly connected in the threaded hole. The cylinder 31 is fixedly provided at the bottom of the support plate 22 through a mounting frame. A plurality of strip-shaped limiting sliders are evenly and fixedly provided on the inner wall of the cylinder 31. A plurality of guiding chutes are evenly formed on the outer wall of the conical column 36 on the side away from the limiting component 34. The plurality of guiding chutes are respectively slidably sleeved on the outer walls of the strip-shaped limiting sliders at corresponding positions.

[0033] In an embodiment of the present invention, the limiting component 34 includes a sleeve 341 and a support rod 342 slidably penetrating through the sleeve 341. A circular groove is formed at one end of the support rod 342. A ball 343 is rotatably disposed in the circular groove. And a V-shaped limiting frame 344 is fixedly provided at the other end of the support rod 342. An annular plate is also fixedly sleeved on the outer wall of the support rod 342.

[0034] In an embodiment of the present invention, a spring 345 is slidably sleeved on the outer wall of the support rod 342 and located between the sleeve 341 and the annular plate. A sliding sleeve 346 is fixedly provided at the bottom of the support rod 342. The sliding sleeve 346 is slidably sleeved on the outer wall of the arc block 33 at the corresponding position. And the sliding sleeve 346 and the arc block 33 are locked by threads. The ball 343 is slidably disposed on the outer wall of the conical column 36.

[0035] During use, adjust the position of the limit component 34 according to the number and position of the main reinforcement bars 11 in the reinforcement cage assembly 1. First, release the lock between the sliding sleeve 346 and the arc-shaped block 33, and then slide the sliding sleeve 346 with reference to the first scale wire groove 35 until the V-shaped limit frame 344 in the limit component 34 at this position just faces one of the main reinforcement bars 11. Then, lock the sliding sleeve 346 and the arc-shaped block 33. Taking this as an example, adjust the positions of the limit components 34 at multiple other positions in the same way. Next, start the servo motor 37 to drive the lead screw 38 to rotate. The lead screw 38 drives the tapered column 36 to move away from the servo motor 37. Since the balls 343 in multiple limit components 34 are all slidably arranged on the outer wall of the tapered column 36, multiple support rods 342 slide along the sleeve 341, and the V-shaped limit frame 344 gradually slides towards one of the main reinforcement bars 11 until the V-shaped groove of the V-shaped limit frame 344 is clamped on the outer wall of the main reinforcement bar 11. The axial direction of the reinforcement cage assembly 1 is restricted by the V-shaped limit frame 344 and cannot rotate, and the stirrup 12 is blocked by the V-shaped limit frame 344 and cannot move.

[0036] Taking the case of installing two acoustic logging tube bodies 51 as an example, set an appropriate number of pre-support components 421 according to the total length of the reinforcement cage assembly 1. Then, in each pre-support component 421, with reference to the positions of two first marking grooves 4213 on the mounting disc 4211 and in symmetric positions, fix the two support arm units 4215 at the positions of the first marking grooves 4213 in symmetric positions by bolts. Then, adjust the length of the extended arm a3 protruding from the extension arm a1 according to the inner diameter size of the current reinforcement cage assembly 1, so that the sum of the total lengths of the mounting disc 4211, the extended arms a3 on both sides of the mounting disc 4211, the extension arm a1, the base arm a2, the upper clamp 4216, the lower clamp 4217, and the arc-shaped sleeve 4218 is adapted to the inner diameter of the reinforcement cage assembly 1, that is, the arc-shaped sleeves 4218 on both sides can just be slidably arranged on the outer walls of two main reinforcement bars 11 in symmetric positions in the reinforcement cage assembly 1. Then, lock the extended arm a3 and the extension arm a1 with fastening bolts. It should be noted here that the inner diameters of the upper clamp 4216, the lower clamp 4217, and the arc-shaped sleeve 4218 are respectively adapted to the outer diameters of the acoustic logging tube body 51 to be installed and the outer diameter of the main reinforcement bar 11.

[0037] Next, place the adjusted pre-support components 421 in a straight line at equal intervals in sequence, and then screw the two ends of the connecting rod 422 into the second threaded sleeves 4212 in adjacent two pre-support components 421 to complete the connection of the two pre-support components 421.

[0038] Next, when installing one of the pre-support components 421 and the acoustic detection tube body 51, first remove the upper clamp 4216, then place the acoustic detection tube body 51 in the arc groove of the lower clamp 4217, and then fix the upper clamp 4216 on the extension arm a1, and use bolts to lock the upper clamp 4216 and the acoustic detection tube body 51. Similarly, the connection method of the upper clamp 4216, the lower clamp 4217 and the acoustic detection tube body 51 at other positions is the same as the above method.

[0039] Next, the first threaded sleeve 412 at one end of the traction assembly 41 is connected through the connecting rod 43, and then the slider 416 is moved with reference to the second scale groove 415, so that the grooves on the outer walls of the rubber guide wheels 417 on both sides can be slidably mounted on the outer walls of the two main ribs 11 in relative positions.

[0040] Next, the traction assembly 41 is placed into the steel cage assembly 1, and the rubber guide wheels 417 on both sides are slidably set on the outer wall of the main reinforcement 11 at the relative position, the lifting belt 26 is sleeved on the traction hook 413, and the electric hoist 24 is used to reel in the wire rope 25. The wire rope 25 pulls the traction assembly 41 to move at a low and uniform speed. Whenever a pre-support assembly 421 enters the steel cage assembly 1, manual assistance and the arc-shaped sleeve 4218 in the pre-support assembly 421 are required to be sleeved on the outer wall of the main reinforcement at the corresponding position. When the acoustic detection tube body 51 moves to the preset position, the connecting rod 43 and the pre-support assembly 421 are separated, and the traction assembly 41 is pulled out of the steel cage assembly 1, and multiple blocking plates 4219 are fixedly connected by bolts and two arc-shaped sleeves 4218 at multiple positions, and the main reinforcement 11 is located between the blocking plate 4219 and the two arc-shaped sleeves 4218. At this point, the acoustic detection tube completes the threading and connection operation of the steel cage assembly 1.
