Description

Technical Field

[0001] The utility model relates to the technical field of pulling devices for building detection, and more specifically, it relates to a pulling device for building detection. Background Art

[0002] In the current field of building detection, a pulling device is a commonly used equipment for pulling tests on steel bars to evaluate their tensile strength and construction quality. However, existing technologies have some problems and limitations in practical applications, which have an adverse impact on the detection efficiency and accuracy.

[0003] First of all, existing pulling devices mostly rely on manual operation, which means that when conducting pulling tests on steel bars, testers need to operate the device themselves. This manual operation is not only time-consuming and laborious, but also may lead to inaccurate test results due to human factors during the operation. For example, inconsistent operation force or insufficient operation skills may affect the accurate measurement of the pulling force, thus having a negative impact on the reliability of the detection results.

[0004] Secondly, conventional pulling detection equipment generally uses flat-shaped universal clamping parts to clamp steel bars. Such clamping parts cannot adapt to steel bars of different specifications and shapes, resulting in difficulty in achieving stable and uniform clamping in practical applications. Unstable clamping not only affects the accurate measurement of the pulling force, but also may damage the steel bars, reducing the detection efficiency. In addition, due to the incomplete matching between the clamping parts and the steel bars, sliding may occur during the test, further affecting the accuracy of the detection results.

[0005] In addition, to solve the above problems, some existing devices attempt to be installed by using two connecting sleeves to adapt to steel bars of different specifications. However, this design is relatively cumbersome in actual operation and requires testers to spend more time on installation and adjustment. This cumbersome operation process not only prolongs the detection preparation time, but also greatly reduces the operation efficiency in the case of frequently replacing steel bars of different specifications, affecting the continuity and efficiency of the detection work.

The straight groove 3 is opened on the side wall of the fixed sleeve 2. The outer side of the adjusting sleeve 4 is slidably arranged in the straight groove 3, and the adjusting sleeve 4 is movably arranged inside the fixed sleeve 2. The sliding groove 5 is opened inside the fixed sleeve 2, and the two sliding grooves 5 arranged on both sides are mirror-designed. The matching block 6 is fixedly connected to one side of the sliding block 7, the sliding block 7 is fixedly connected to one side of the sliding plate 9. The matching groove 8 is opened on the adjusting sleeve 4, and the matching block 6 is adapted to the matching groove 8. The sliding plate 9 is slidably arranged in the sliding groove 5. An adjusting mechanism is arranged on the outer side of the fixed sleeve 2. The adjusting mechanism includes a driven wheel 10, a driving wheel 11, a reduction motor 12, a spiral groove 13, a ball 14, a mounting sleeve 15 and a rotating sleeve 16. The driven wheel 10 is fixedly arranged on the outer side of the rotating sleeve 16. The driving wheel 11 meshes with the driven wheel 10. The reduction motor 12 is detachably installed on one side of one of the mounting sleeves 15, and the output end of the reduction motor 12 is connected to the driving wheel 11. The spiral groove 13 is opened inside the rotating sleeve 16, and the two spiral grooves 13 arranged on both sides are mirror-designed. The ball 14 is rollably arranged in the spiral groove 13. The mounting sleeve 15 is detachably sleeved on the outer side of the fixed sleeve 2 through threads, and the rotating sleeve 16 is rotatably sleeved on the outer side of the fixed sleeve 2.

[0033] A rubber plate 19 is arranged on one side of the clamping plate 18, and the rubber plate 19 is fixedly connected to the inner side of the clamping plate 18.

[0034] A steel bar 20 is arranged on one side of the clamping plate 18, and the steel bar 20 is detachably arranged inside the fixed sleeve 2.

[0035] In this embodiment, when it is necessary to perform a pulling test on different steel bars 20, first, turn on the reduction motor 12 installed on one side of the mounting sleeve 15. The reduction motor 12 drives the driving wheel 11 to rotate. Then, the driving wheel 11 drives the driven wheel 10 engaged with it to rotate. Then, the driven wheel 10 drives the rotating sleeve 16 to rotate. Then, the rotating sleeve 16 drives the spiral groove 13 arranged inside to rotate. Due to the special structural design of the spiral groove 13, and the two sides of the ball 14 can be movably installed in the spiral groove 13 and the adjusting sleeve 4 respectively. At the same time, since the straight groove 3 limits the outside of the adjusting sleeve 4, then the ball 14 will slide and roll along the spiral groove 13. Since the two spiral grooves 13 are mirror-like structures, then the two adjusting sleeves 4 will move inward simultaneously. Then, the two adjusting sleeves 4 will drive the corresponding sliding blocks 7 to move respectively through the cooperation of the adapter blocks 6 and the adapter grooves 8. Then, the sliding block 7 will drive the sliding plate 9 arranged on one side to slide along the sliding groove 5. Since the sliding groove 5 and the sliding plate 9 are of an inclined structural design, and the two sliding grooves 5 are of a symmetrical structural design, then the sliding plate 9 will drive the sliding blocks 7 to spread outward simultaneously, and the sliding block 7 will drive the adapter block 6 arranged on one side to slide along the adapter groove 8. At the same time, the sliding block 7 will drive the push spring 17 connected to one side to gradually reset, and the clamping plate 18 connected to the other end of the push spring 17 will no longer clamp the side wall of the steel bar 20. Then, the steel bar 20 can be withdrawn from the fixing sleeve 2, and the reduction motor 12 can be temporarily turned off. Then, the steel bar 20 to be tested is reinserted into the inner side of the fixing sleeve 2. Then, turn on the reduction motor 12 and make the reduction motor 12 reverse. Then, the reduction motor 12 drives the driven wheel 10 to reverse through the driving wheel 11 connected to the output end. Then, the rotating sleeve 16 drives the spiral groove 13 to reverse. Then, the adjusting sleeve 4 drives the ball 14 to reset along the spiral groove 13. Then, the adjusting sleeve 4 pushes the sliding block 7 and the sliding plate 9 to reset along the sliding groove 5, and the sliding block 7 drives the adapter block 6 connected to one side to drive the adapter groove 8 to reset. Then, the sliding block 7 clamps the side wall of the steel bar 20 through the cooperation of the push spring 17 and the clamping plate 18. The setting of the rubber plate 19 can further increase the friction between the inner side of the clamping plate 18 and the outer wall of the steel bar 20, thereby further improving the clamping stability. After the clamping plate 18 completely clamps the steel bar 20, turn off the reduction motor 12.

[0036] Please refer to Figure 1 , as an implementation manner of the detection device: The detection device includes a connection seat 21, a lead screw 22, a threaded sleeve 23, a fixed seat 24, and a mounting seat 25. The connection seat 21 is detachably installed on the base 1. The lead screw 22 is movably installed on the connection seat 21 and the mounting seat 25. The threaded sleeve 23 is detachably arranged below the fixed seat 24, and the threaded sleeve 23 is movably sleeved on the lead screw 22 through a thread. The mounting seat 25 is detachably installed on the other side of the base 1.

[0037] A sliding sleeve 26 is provided below the fixed seat 24. Brackets 27 are symmetrically provided on both sides of the mounting seat 25. A sliding rod 28 is provided on the bracket 27, and the sliding sleeve 26 is slidably sleeved on the sliding rod 28.

[0038] A drive motor 29 is detachably provided on one side of the mounting seat 25, and the output end of the drive motor 29 is connected to one end of the lead screw 22.

[0039] Opposite threads are symmetrically provided at both ends of the lead screw 22.

[0040] More specifically, when the steel bar 20 needs to be subjected to a pulling test, first, the steel bar 20 is stably clamped by the clamping device. Then, the drive motor 29 installed on one side of the mounting seat 25 is turned on. The drive motor 29 drives the lead screw 22 to rotate. Since the threads provided at both ends of the lead screw 22 are of a symmetrical structure, and the sliding rod 28 and the sliding sleeve 26 limit the fixed seat 24, then the two fixed seats 24 will drive the clamping device installed above to move outward simultaneously, and the fixed seat 24 will drive the sliding sleeve 26 to rotate along the sliding rod 28, thereby realizing the pulling test of the steel bar 20. After the test is completed, the drive motor 29 is turned off, and then the steel bar 20 can be removed.

[0041] In summary, when the overall device is in use or operation: When it is necessary to perform a tensile test on different steel bars 20, first turn on the reduction motor 12 installed on one side of the installation sleeve 15. The reduction motor 12 drives the driving wheel 11 to rotate. Then, the driving wheel 11 drives the driven wheel 10 engaged therewith to rotate. Then, the driven wheel 10 drives the rotating sleeve 16 to rotate. Then, the rotating sleeve 16 drives the spiral groove 13 provided inside to rotate. Due to the special structural design of the spiral groove 13, and the two sides of the ball 14 can be movably installed in the spiral groove 13 and the adjusting sleeve 4 respectively. At the same time, since the straight groove 3 limits the outside of the adjusting sleeve 4, then the ball 14 will slide and roll along the spiral groove 13. Since the two spiral grooves 13 are mirror structures, then the two adjusting sleeves 4 will move inward at the same time. Then, the two adjusting sleeves 4 will drive the corresponding sliding blocks 7 to move through the cooperation of the fitting blocks 6 and the fitting grooves 8 respectively. Then, the sliding block 7 will drive the sliding plate 9 provided on one side to slide along the sliding groove 5. Since the sliding groove 5 and the sliding plate 9 are of an inclined structural design, and the two sliding grooves 5 are of a symmetric structural design, then the sliding plate 9 will drive the sliding block 7 to spread outward at the same time, and the sliding block 7 will drive the fitting block 6 provided on one side to slide along the fitting groove 8. At the same time, the sliding block 7 will drive the push spring 17 connected to one side to gradually reset, and the clamping plate 18 connected to the other end of the push spring 17 will no longer clamp the side wall of the steel bar 20. Then, the steel bar 20 can be withdrawn from the fixing sleeve 2 and the reduction motor 12 can be temporarily turned off. Then, the steel bar 20 to be tested is reinserted into the inside of the fixing sleeve 2, and then the reduction motor 12 is turned on and the reduction motor 12 is reversed. Then, the reduction motor 12 drives the driven wheel 10 to reverse through the driving wheel 11 connected to the output end. Then, the rotating sleeve 16 drives the spiral groove 13 to reverse. Then, the adjusting sleeve 4 drives the ball 14 to reset along the spiral groove 13. Then, the adjusting sleeve 4 pushes the sliding block 7 and the sliding plate 9 to reset along the sliding groove 5, and the sliding block 7 will drive the fitting block 6 connected to one side to drive the fitting groove 8 to reset. Then, the sliding block 7 will clamp the side wall of the steel bar 20 through the cooperation of the push spring 17 and the clamping plate 18. The setting of the rubber plate 19 can further increase the friction between the inside of the clamping plate 18 and the outer wall of the steel bar 20, thereby further improving the clamping stability. After the clamping plate 18 completely clamps the steel bar 20, the reduction motor 12 can be turned off.

[0042] When it is necessary to conduct a pulling test on the steel bar 20, first, the steel bar 20 is stably clamped by the clamping device. Then, the driving motor 29 installed on one side of the mounting base 25 is turned on. The driving motor 29 drives the lead screw 22 to rotate. Since the threads provided at both ends of the lead screw 22 are of a symmetrical structure, and the slide bar 28 and the sliding sleeve 26 limit the fixed seat 24, the two fixed seats 24 will drive the clamping device installed above to move outward simultaneously, and the fixed seat 24 will drive the sliding sleeve 26 to rotate along the slide bar 28, thereby realizing the pulling test on the steel bar 20. After the test is completed, turn off the driving motor 29, and then remove the steel bar 20.
