Description

Technical Field

[0001] This invention relates to the field of anchor bolt processing equipment technology, and more specifically, to an anchor bolt performance testing device. Background Technology

[0002] Anchor bolts are a general term for all post-anchoring components, encompassing a wide range. They are classified by raw materials into metal anchor bolts and non-metal anchor bolts, and by anchoring mechanism into expansion anchor bolts, borehole anchor bolts, bonded anchor bolts, concrete screws, shot nails, concrete nails, etc. After processing, anchor bolts require performance testing. Testing items include stress relaxation performance, nut guarantee load, reduction of area, elongation after fracture, specified non-proportional elongation stress, and tensile strength. However, most anchor bolt testing is destructive, resulting in varying deformations after testing. Therefore, sampling is necessary for testing, and the quality of anchor bolts within the same batch must be determined.

[0003] In existing technologies, when testing the tensile strength of anchor bolts, the upper end of the anchor bolt is usually fixed first, and then a nut is screwed on the lower end of the anchor bolt. The nut is then pulled downwards, and the tensile force is tested. If the anchor bolt does not break when a certain tensile force is reached, it is considered a qualified product. However, there are some problems in its use. The upper end of the anchor bolt is conical and the lower end is cylindrical. When tightening the nut, the anchor bolt and the nut are prone to rotating together, making it inconvenient to tighten the nut. Furthermore, if the anchor bolt is of substandard quality and breaks inside the nut, it is also inconvenient to remove the broken anchor bolt, thus affecting work efficiency.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Summary of the Invention

[0012] Furthermore, the lifting frame includes a first electric telescopic rod installed on both sides of the upper surface of the workbench. A lifting block is installed at the telescopic end of the first electric telescopic rod. The lifting block is connected to the trapezoidal block and the circular lifting platform. A lifting plate is installed on one side of the telescopic end of the first electric telescopic rod. When the first electric telescopic rod moves the lifting plate downward, it can push the support plate downward.

[0013] Furthermore, a collection box is placed above the workbench, and the collection box is located below the circular rotating platform.

[0014] Furthermore, the holding block includes a cuboid block, with limit blocks installed on the four side surfaces of the cuboid block. One end of the limit block extends into the limit slide. A conical groove is opened at the upper end of the cuboid block, and a round hole is opened at the lower end of the conical groove. The conical end of the anchor bolt is placed in the conical groove, and the threaded end of the anchor bolt extends through the round hole to the bottom of the cuboid block. The limit block can be moved onto the pressure sensor.

[0015] Furthermore, the limiting slide is L-shaped. A rotary motor is installed on one side of the upper surface of the worktable. The rotating end of the rotary motor is connected to a rotating screw through a coupling. The rotating screw is connected to a screw sleeve through a thread. A screw bearing is installed at one end of the rotating screw. The screw bearing is installed on the upper surface of the limiting slide through a support shaft. A push plate is installed at the lower end of the screw sleeve. A buffer plate is provided on one side of the push plate. The buffer plate and the push plate are connected by multiple spring pins. One end of the limiting slide on the outer side has an inlet and outlet. A push block is provided at the inlet and outlet. A second electric telescopic rod is installed on the upper surface of the worktable. The telescopic end of the second electric telescopic rod is connected to one side of the push plate.

[0018] The beneficial effects of this invention are as follows: By moving the two first arc-shaped nuts and the second arc-shaped nut, the threaded end of the anchor bolt can be clamped, eliminating the need to tighten the nuts for a long time. The nuts can be put on the lower end of the anchor bolt, and the anchor bolt can be loosened easily, which can improve work efficiency. If the anchor bolt breaks, the broken anchor bolt can be easily removed by separating the nuts, which facilitates the testing of subsequent anchor bolts. Workers can put anchor bolts from different batches into the holding block. After the test is completed, workers can observe which anchor bolt in the holding block is broken, which can tell which batch of anchor bolts is unqualified. By eliminating the need for workers to observe from one side for a long time, the labor intensity of workers is reduced.

[0019] The two second arc-shaped nuts can rotate. If the second arc-shaped nuts cannot drive the anchor bolt to rotate, the threads of the two nuts can be engaged when the second arc-shaped nuts rotate. If the friction between the second arc-shaped nuts and the anchor bolt is large, the first arc-shaped nut will not rotate when the second arc-shaped nuts and the anchor bolt rotate together. This allows the threads of the first arc-shaped nut and the anchor bolt to be engaged, making it easier to screw the nut onto the anchor bolt and improving work efficiency.

[0020] When the two first arc-shaped nuts and the two second arc-shaped nuts are in the separated state, the push plate is moved by rotating the screw, which facilitates material changing and allows multiple holding blocks to be placed in the limiting slide, making it easier to position the holding blocks and making it more convenient to use.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. 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.

[0032] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] This invention provides, for example Figure 1-9An anchor bolt performance testing device, as shown, includes a workbench 1. Two limiting slides 2 are mounted on the upper end of the workbench 1. The limiting slides 2 are mounted on the workbench 1 via multiple support legs 3. A threading mechanism and a testing mechanism are mounted on the workbench 1. The threading mechanism includes multiple holding blocks 4 between the two limiting slides 2. Both ends of the holding blocks 4 extend into the limiting slides 2, and anchor bolts 5 are placed inside the holding blocks 4. First arc-shaped nuts 6 are provided on both sides above the workbench 1, and second arc-shaped nuts 6 are provided below the first arc-shaped nuts 6. The first arc-shaped nut 6 is mounted on one side of the mother 7, and the pusher 8 can push the first arc-shaped nut 6 to the threaded end of the anchor bolt 5. The pusher 8 can also push the second arc-shaped nut 7 to the threaded end of the anchor bolt 5. The detection mechanism includes a square groove 9 located on one side of the lower end of the limiting slide 2. A pressure sensor 10 is installed in the square groove 9. The holding block 4 can be moved onto the pressure sensor 10. A lifting frame 11 is installed on the worktable 1. The lifting frame 11 can drive the first arc-shaped nut 6 and the second arc-shaped nut 7 to move downward.

[0034] The process of this device detecting anchor bolt 5 is as follows: Multiple holding blocks 4 are placed in the limiting slide 2. Workers sample anchor bolts 5 from different batches and place them into the holding blocks 4. Under normal conditions, the two first arc-shaped nuts 6 and the two second arc-shaped nuts 7 are separated. By moving the holding blocks 4, the anchor bolt 5 can be moved. When the anchor bolt 5 moves between the two first arc-shaped nuts 6 and the two second arc-shaped nuts 7, the holding block 4 moves onto the pressure sensor 10. The pusher 8 then moves the two first arc-shaped nuts 6 and the two second arc-shaped nuts 7 towards the anchor bolt 5, clamping the threaded end of the anchor bolt 5. The lifting frame 11 can then move the first arc-shaped nuts 6 and the two second arc-shaped nuts 7 towards the anchor bolt 5. The mother 7 moves downwards, allowing the anchor bolt 5 to be pulled out for testing. The pressure sensor 10 detects the tensile force borne by the anchor bolt 5. If the specified value is reached and the anchor bolt 5 is not broken, it is a qualified product. If the anchor bolt 5 is broken, it is a defective product. After testing one anchor bolt 5, the pusher 8 drives the two first arc-shaped nuts 6 and the two second arc-shaped nuts 7 to move away from the anchor bolt 5, thereby loosening and avoiding the anchor bolt 5. By moving the holding block 4, the next anchor bolt 5 can be tested. If the anchor bolt 5 is broken, the two first arc-shaped nuts 6 and the two second arc-shaped nuts 7 will separate, causing the broken part of the anchor bolt 5 to fall off, which facilitates the testing of the next anchor bolt 5.

[0035] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 3The pusher frame 8 includes a circular holding platform 12 located below the second arc-shaped nut 7. Fixed platforms 13 are installed on both sides of the upper end of the circular holding platform 12. Guide holes 14 are opened at the upper ends of the fixed platforms 13. A guide block 15 is installed on one side surface of the second arc-shaped nut 7. One end of the guide block 15 extends through the guide hole 14 to the outside of the second arc-shaped nut 7. A connecting rod 16 is installed on one side of the lower surface of the guide block 15. A first universal ball bearing 17 is installed at one end of the connecting rod 16. The connecting rod 16 and the circular holding platform 12 are connected by a first telescopic spring 18. The worktable 1... A circular lifting platform 19 is provided above, with a conical hole 20 inside the circular lifting platform 19. A limit rod 21 is installed on one side of the first arc-shaped nut 6, and a limit cylinder 22 is fitted on the outside of the limit rod 21. The limit cylinder 22 is installed on the circular holding platform 12. A pulley 23 is installed at one end of the limit rod 21, and a trapezoidal block 24 is provided on one side of the pulley 23. A moving plate 25 is installed at the lower end of the limit rod 21. The moving plate 25 and the limit cylinder 22 are connected by a second telescopic spring 26. The lifting frame 11 can drive the circular lifting platform 19 and the trapezoidal block 24 to move up and down.

[0036] The process of the pusher 8 moving the two first arc-shaped nuts 6 and the two second arc-shaped nuts 7 is as follows: When the lifting frame 11 moves the trapezoidal block 24 downward, the inclined plane can push the limiting rod 21 towards the anchor bolt 5. The pulley 23 can reduce the friction between the limiting rod 21 and the trapezoidal block 24, thus facilitating the fitting of the two first arc-shaped nuts 6 onto the threaded end of the anchor bolt 5. When the limiting rod 21 moves, the second telescopic spring 26 can be compressed. The limiting cylinder 22 can ensure the direction of movement of the limiting rod 21. When the lifting frame 11 moves the circular lifting platform 19 downward, the inclined plane of the tapered hole 20 can push the connecting rod 16 and the guide block 15 towards the anchor bolt 5, thus facilitating the fitting of the two first arc-shaped nuts 6 onto the threaded end of the anchor bolt 5. Two second arc-shaped nuts 7 are fitted onto the threaded ends of the anchor bolt 5. When the connecting rod 16 moves, the first telescopic spring 18 can be compressed. The guide block 15 and the guide hole 14 can ensure the direction of movement of the connecting rod 16. Then, the lower end of the anchor bolt 5 can be clamped by the two first arc-shaped nuts 6 and the two second arc-shaped nuts 7. When it is necessary to loosen the anchor bolt 5, the trapezoidal platform 24 and the circular lifting platform 19 can be moved upward by the lifting frame 11. Then, the connecting rod 16 and the limiting rod 21 can be relaxed. Then, under the elastic force of the first telescopic spring 18 and the second telescopic spring 26, the connecting rod 16 and the limiting rod 21 can be returned to their original positions, and the two first arc-shaped nuts 6 and the two second arc-shaped nuts 7 can be returned to their original positions, thus loosening the anchor bolt.

[0037] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 3The circular holding platform 12 includes a circular rotating platform 27. A rolling bearing 28 is installed at the lower end of the circular rotating platform 27. A support plate 29 is installed at one end of the rolling bearing 28. The limiting cylinder 22 includes a square sleeve 30. Support blocks 31 are installed at both ends of the square sleeve 30. A support rod 32 is installed at the lower end of the support block 31. The lower end of the support rod 32 is fixedly connected to the upper surface of the support plate 29. A first telescopic spring 18 is connected to the circular rotating platform 27 on the circular holding platform 12. Multiple guide rods 33 are installed on the lower surface of the support plate 29. A guide cylinder 34 is fitted on the outside of the guide rod 33. The upper surface of the worktable 1 is installed at the lower end of the guide cylinder 34. A third telescopic spring 35 is installed on the lower surface of the guide rod 33. The lower end of the third telescopic spring 35 is connected to the upper surface of the worktable 1.

[0038] The process of the circular holding platform 12 supporting the two first arc-shaped nuts 6 and the two second arc-shaped nuts 7 is as follows: Under normal conditions, the guide rod 33 can support the support plate 29, the rolling bearing 28, and the circular rotating platform 27 under the elastic force of the third telescopic spring 35. The circular rotating platform 27 can support the second arc-shaped nuts 7 through the fixing block 13. The support plate 29 can support the square sleeve 30 through the support rod 32. The square sleeve 30 can support the limiting rod 21, which facilitates the support of the first arc-shaped nuts 6.

[0039] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 3 A servo motor 36 is installed on one side of the lower surface of the support plate 29. A first gear 37 is installed on the rotating end of the servo motor 36. A second gear 38 is installed on the lower end of the circular rotating table 27. The first gear 37 and the second gear 38 mesh.

[0040] The rotation process of the annular rotating platform 27 is as follows: The servo motor 36 is started to rotate, which drives the first gear 37 to rotate. The first gear 37 meshes with the second gear 38, driving the second gear 38 and the annular rotating platform 27 to rotate. When the annular rotating platform 27 rotates, it drives the guide block 15, the second arc-shaped nut 7, and the connecting rod 16 to rotate through the fixing block 13. The conical hole 20 on the inner side of the annular lifting platform 19 prevents the connecting rod 16 from moving when it rotates, thus ensuring that the second arc-shaped nut 7 is tightly attached to the lower end of the anchor bolt 5. When the second arc-shaped nut 7 rotates, if the friction between the second arc-shaped nut 7 and the anchor bolt 5 is small, the second arc-shaped nut 7 can rotate while the anchor bolt 5 does not rotate, allowing the threads between the second arc-shaped nut 7 and the anchor bolt 5 to engage, facilitating the connection between the second arc-shaped nut 7 and the anchor bolt 5. If the friction between the second arc-shaped nut 7 and the anchor bolt 5 is large, the second arc-shaped nut 7 and the anchor bolt 5 will rotate together, while the first arc-shaped nut 6 will not rotate, allowing the threads on the anchor bolt 5 to engage, thus facilitating the clamping of the lower end of the anchor bolt 5 and making it easier to inspect.

[0041] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 3 The lifting frame 11 includes a first electric telescopic rod 39 installed on both sides of the upper surface of the workbench 1. A lifting block 40 is installed at the telescopic end of the first electric telescopic rod 39. The lifting block 40 is connected to the trapezoidal block 24 and the circular lifting platform 19. A lifting plate 41 is installed on one side of the telescopic end of the first electric telescopic rod 39. When the first electric telescopic rod 39 moves the lifting plate 41 downward, it can push the support plate 29 downward.

[0042] The process of lifting the trapezoidal block 24 and the circular lifting platform 19 by the lifting frame 11 is as follows: The first electric telescopic rod 39 is activated and shortened. The first electric telescopic rod 39 can drive the lifting block 40 to move downwards. The lifting block 40 can drive the trapezoidal block 24 and the circular lifting platform 19 to move downwards. When the first electric telescopic rod 39 shortens, it can drive the lifting plate 41 to move downwards. After the two first arc-shaped nuts 6 and the two second arc-shaped nuts 7 clamp the threaded end of the anchor bolt 5, the lifting plate 41 can contact the upper surface of the support plate 29. Then, the support plate 29 can be pulled downwards, and through the rolling bearing 28, the circular rotating platform 27, and the fixed... The fixed block 13 and guide block 15 pull the second arc-shaped nut 7 downwards. The first arc-shaped nut 6 can be pulled downwards through the support rod 32, support block 31, square sleeve 30, and limit rod 21, which facilitates the pull-out test of the anchor bolt 5. When the support plate 29 moves downwards, the guide rod 33 can move downwards and compress the third telescopic spring 35. After the test is completed, the first electric telescopic rod 39 is extended, which can drive the lifting block 40, trapezoidal block 24, circular lifting platform 19, and lifting plate 41 to move upwards. Under the elastic force of the third telescopic spring 35, the support plate 29 automatically returns to its original position.

[0043] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 3 A collection box 42 is placed above the workbench 1. The collection box 42 is located below the circular rotating table 27. The collection box 42 can collect the broken parts of the anchor bolt 5.

[0044] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 4 Instruction manual attached Figure 5 Included with instruction manual Figure 7The container block 4 includes a cuboid block 43. Limiting blocks 44 are installed on the four side surfaces of the cuboid block 43. One end of the limiting block 44 extends into the limiting slide 2. A conical groove 45 is opened at the upper end of the cuboid block 43, and a circular hole 46 is opened at the lower end of the conical groove 45. The conical end of the anchor bolt 5 is placed in the conical groove 45, and the threaded end of the anchor bolt 5 extends through the circular hole 46 to the bottom of the cuboid block 43. The limiting block 44 can be moved onto the pressure sensor 10. One end of the limiting block 44 can extend into the limiting slide 2, thereby ensuring the direction of movement of the cuboid block 43. The conical groove 45 fits with the conical end of the anchor bolt 5, which can ensure the complete transmission of pressure. The lower end of the limiting block 44 presses on the pressure sensor 10, which can facilitate pressure detection.

[0045] Refer to the instruction manual appendix Figure 4 Instruction manual attached Figure 5 Instruction manual attached Figure 6 Included with instruction manual Figure 8 The limiting slide 2 is L-shaped. A rotary motor 47 is installed on one side of the upper surface of the worktable 1. The rotating end of the rotary motor 47 is connected to a rotating screw 48 via a coupling. The rotating screw 48 is connected to a screw sleeve 49 via a thread. A screw bearing 50 is installed at one end of the rotating screw 48. The screw bearing 50 is installed on the upper surface of the limiting slide 2 via a support shaft 51. A push plate 52 is installed at the lower end of the screw sleeve 49. A buffer plate 53 is provided on one side of the push plate 52. The buffer plate 53 and the push plate 52 are connected by multiple spring pins 54. One end of the limiting slide 2 on the outer side has an inlet / outlet 55. A push block 56 is provided at the inlet / outlet 55. A second electric telescopic rod 57 is installed on the upper surface of the worktable 1. The telescopic end of the second electric telescopic rod 57 is connected to one side of the push plate 52. The lower ends of the push plate 52 and the buffer plate 53 extend between the two limiting slides 2. When the operator puts in the holding block 4, he first puts it all into one longitudinal end. The screw sleeve 49 is located in the limiting position. At the starting end of slide 2, the rotary motor 47 is started to rotate, which drives the rotating screw 48 to rotate. Through the threaded connection between the rotating screw 48 and the screw sleeve 49, the screw sleeve 49 can be moved. The screw sleeve 49 can push the holding block 4 through the push plate 52 and the buffer plate 53. The spring pin 54 can reduce the error when the screw sleeve 49 moves and give the holding block 4 sufficient pressure. When the holding block 4 moves to the longitudinal end of the limiting slide 2, the holding block 4 and the anchor bolt 5 can be positioned. Then the anchor bolt 5 can be inspected. After the inspection is completed, the second electric telescopic rod 57 is started to extend. The second electric telescopic rod 57 can push the holding block 4 at the end to the transverse position of the limiting slide 2 through the push block 56. Then the second electric telescopic rod 57 is shortened and the push block 56 is brought back to its original position. Then the rotary motor 47 is started to rotate and drive the screw sleeve 49 to move, which makes it easier to change the anchor bolt 5.
