Description

Technical Field

[0001] The present invention relates to the technical field of anchor bolt experiments, and particularly relates to a multi-functional comprehensive test platform for anchor bolt experiments. Background Art

[0002] An anchor bolt is a component in the prior art for installing mechanical equipment or building components on a concrete slab. By drilling an installation hole in the concrete slab, then moving the anchor bolt into the installation hole of the concrete slab, and then using the reaming ability of the anchor bolt to make the outer wall of the anchor bolt fit tightly with the inner wall of the installation hole, so that the anchor bolt fits tightly with the concrete slab. Then, the mechanical equipment and building components can be connected to the area where the anchor bolt protrudes outside the concrete slab, thereby installing the mechanical equipment and building components on the concrete slab. During the production process of the anchor bolt, when producing a batch of anchor bolts, it is necessary to conduct experiments on the first few produced anchor bolts to judge the use quality of the anchor bolts. The experimental quality inspection of the anchor bolts mainly includes geometric dimension detection and pull-out detection of the anchor bolts;

[0003] The general method for the prior art to conduct pull-out detection on anchor bolts is to install the anchor bolt on the concrete slab, then install a fixed installation part on the anchor bolt, move the concrete slab to the bottom of the output end of the press equipment, install a tensile tester on the output end of the press equipment, connect the tensile tester with the fixed installation part, and then drive the tensile tester by the output end of the press equipment to conduct pull-out on the fixed installation part and the anchor bolt, so as to detect the fixing situation between the anchor bolt and the concrete slab. After the detection, the cracks in the area near the anchor bolt on the concrete slab are detected to judge whether the anchor bolt can remain fixed in the concrete slab under specific tensile force;

[0004] However, in the actual use process of the anchor bolt, the vibration effect it receives is usually all-round. Therefore, only conducting an upward pull-out detection experiment on the anchor bolt is not conducive to accurately experimenting on the use effect of the anchor bolt. And because the surface volume of the experimental concrete slab generally corresponds to the installation coverage area during the installation process of the anchor bolt, generally only one anchor bolt can be detected with the experimental concrete slab. However, the installation coverage areas of anchor bolts with different volumes are not the same. After detecting a relatively large anchor bolt with the concrete slab, there are still unused areas and areas that maintain sufficient stress of the concrete slab on other end faces of the concrete slab. The prior art does not make good use of the overall area of the concrete slab and has the problem of inconvenient movement of the concrete slab. Summary of the Invention

Detailed implementation manners

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Please refer to Figures 1 to 11 , a multifunctional comprehensive test platform for anchor bolt experiments, including a press equipment 1, a tensile detector 2 is arranged on the output end of the press equipment 1, and further includes a support platform 3. The press equipment 1 is arranged in the middle of the support platform 3. The press equipment 1 is a conventional technical equipment in the prior art for driving an object to move longitudinally, which is a well-known prior art equipment to those skilled in the art. The tensile detector 2 is also a device in the prior art for detecting the force used when the press equipment 1 performs a pulling operation on the anchor bolt, so as to judge the stability of the anchor bolt in the concrete slab.

[0043] Please refer to Figures 1 to 6 and Figure 11, a pushing frame 4 is slidably arranged on one side of the top end of the support platform 3. Two hydraulic drive cylinders 5 are arranged on the top end of the support platform 3. Fixed connection components 6 are fixedly connected to the output ends of the two hydraulic drive cylinders 5. A tensile force detector 2 is also arranged inside the fixed connection component 6. The hydraulic drive cylinder 5 is also an existing device in the prior art for driving an object to move longitudinally, and it is a well-known technical device in the field. After the tensile force detector 2 is connected to the fixed installation part 7, the hydraulic drive cylinder 5 drives the fixed connection component 6 and the tensile force detector 2 to move, so that the tensile force detector 2 can also detect the tensile force of the hydraulic drive cylinder 5 on the anchor bolt, achieving the purpose of conducting a pull-out test on the anchor bolt.

[0044] Please refer to Figures 1 to 6 and Figure 11 , wherein, a meshing connection assembly 100 is arranged between the pushing frame 4 and one of the fixed connection components 6. The meshing connection assembly 100 includes a meshing ring 8, a meshing body 9 and a first electric cylinder 10. A meshing ring 8 is fixedly connected to the outer wall of the fixed connection component 6 corresponding to the pushing frame 4. Meshing grooves are opened at both ends of the meshing ring 8. Meshing bodies 9 are slidably connected to both sides of the pushing frame 4. The meshing bodies 9 are meshed with the meshing grooves on the same side. First electric cylinders 10 are arranged on both sides of the pushing frame 4. The output ends of the first electric cylinders 10 are fixedly connected to the meshing bodies 9 on the same side. When it is necessary to make the hydraulic drive cylinder 5 corresponding to the pushing frame 4 drive the pushing frame 4 to move, when the hydraulic drive cylinder 5 drives the fixed connection component 6 to move, after the fixed connection component 6 and the meshing ring 8 move between the two meshing bodies 9, start the first electric cylinders 10 on both sides to push the meshing bodies 9 to move, so that the meshing bodies 9 are meshed with the meshing ring 8. Thus, when the hydraulic drive cylinder 5 continues to drive the fixed connection component 6 to move, it can drive the pushing frame 4 and the installation frame 15 to move on the support platform 3. And when it is necessary for the hydraulic drive cylinder 5 to conduct a pull-out operation on the anchor bolt, the first electric cylinders 10 can be started to drive the meshing bodies 9 to move, releasing the meshing relationship between the meshing bodies 9 and the meshing ring 8, so that the hydraulic drive cylinder 5 will not drive the pushing frame 4 to move when driving the fixed connection component 6 to move.

[0045] Please refer to Figures 1 to 4, a rotation engagement assembly 200 is provided between the fixed mounting member 7 and the tensile testing instrument 2. The rotation engagement assembly 200 includes a connecting rod 11, a rotating disk 13, and a receiving tooth groove 14. A connecting rod 11 is provided on the working end of the tensile testing instrument 2.

[0046] Please refer to Figures 1 to 4 and Figures 8 to 10, in this embodiment, the movable support mechanism 300 is slidably arranged on the support platform 3. The movable support mechanism 300 is fixedly connected to the pushing frame 4. The movable support mechanism 300 includes a mounting frame 15, a flipping support plate 16, a sliding track 18, a movable damping assembly, a rotating seat 19, a second electric cylinder 20, and a rotating sliding member 21. The mounting frame 15 is slidably connected to the top of the support platform 3, and the mounting frame 15 is fixedly connected to the pushing frame 4. The flipping support plate 16 is rotatably connected to the inside of the mounting frame 15 through a rotating shaft 17. Two sliding tracks 18 are fixedly connected to the inner bottom wall of the support platform 3. A movable damping assembly is arranged between the mounting frame 15 and the sliding track 18. The rotating seat 19 is arranged between the two movable damping assemblies. The second electric cylinder 20 is rotatably arranged on the rotating seat 19. The rotating sliding member 21 is slidably connected to the bottom end of the flipping support plate 16. The output end of the second electric cylinder 20 is rotatably connected to the rotating sliding member 21 through a rotating block 22. In order to damp the downward force generated when the concrete slab moves onto the support platform 3 and to assist the support trough 38 in flipping the concrete slab, first, after the concrete slab moves between the two support troughs 38, during the movement of the pushing frame 4, the mounting frame 15 is driven to move on the support platform 3 together, so that the concrete slab moves to the bottom of the press device 1. When it is necessary to flip the concrete slab around the center point of the drive shaft 45, the second electric cylinder 20 is started to drive the rotating sliding member 21 to slide at the bottom of the flipping support plate 16, thereby pushing the flipping support plate 16 to flip around the center point of the rotating shaft 17 inside the mounting frame 15. Thus, when the drive shaft 45 drives the sliding frame 37 and the support trough 38 to flip upward, the flipping support plate 16 supports the bottoms of the two support troughs 38;

[0047] The mobile shock-absorbing assembly includes a sliding body 23, a sliding support plate 26 and a sliding bracket 27. The sliding body 23 is slidably connected within a sliding track 18.

A rotating seat 19 is arranged on the support plate 25. The sliding support plate 26 is slidably connected within the sliding cylinder body 24. The top end of the sliding support plate 26 is fixedly connected to the bottom of the mounting frame 15. A spring damper is arranged between the sliding support plate 26 and the inner bottom wall of the sliding cylinder body 24. A sliding bracket 27 is slidably connected to the sliding support plate 26. The bottom of the sliding bracket 27 is rotatably connected to a rotating wheel 28. The rotating wheel 28 contacts the inner bottom wall of the support platform 3. After adjusting the distance between the two support troughs 38 according to the volume of the concrete slab, the rotating roller 39 is brought into contact with the top end of the flipping support plate 16. After moving the concrete slab between the two support troughs 38, when the downward pressure of the concrete slab presses down on the support trough 38, it drives the sliding support plate 26 to slide within the sliding cylinder body 24, and the spring damper damps the downward force of the sliding support plate 26. When the pushing frame 4 and the mounting frame 15 are moved horizontally, the rotating wheel 28 moves on the inner bottom wall of the support platform 3, thereby improving the smoothness of the movement of the pushing frame 4 and the mounting frame 15.

[0048] Please refer to Figures 1 to 4, in this embodiment, a plate clamping assembly 400 is provided on the other side of the top end of the support platform 3.

The plate clamping assembly 400 includes a moving box body 29, a third electric cylinder 30, a first bidirectional screw 31, a magnetic chute 33, an electromagnet 35 and a clamping plate 36. The moving box body 29 is slidably connected to the support platform 3. The third electric cylinder 30 is arranged on the support platform 3, and the output end of the third electric cylinder 30 is fixedly connected to the moving box body 29. A first bidirectional screw 31 is rotatably connected inside the moving box body 29.

The electromagnet 35 is magnetically matched with the magnetic chute 33. Clamping plates 36 are fixedly connected to both of the two moving rods 34. After the pushing frame 4 and the mounting frame 15 move the concrete plate to the bottom of the press device 1, according to the volume of the concrete plate, the first driving motor 32 is started to drive the first bidirectional screw 31 to rotate, so that the first bidirectional screw 31 drives the two moving rods 34 to move between the inside of the moving box body 29 and the magnetic chute 33, thereby adjusting the distance between the two clamping plates 36. After adjusting the distance between the two clamping plates 36, the electromagnet 35 is powered to generate a magnetic force, so that magnetic connection is carried out between the electromagnet 35 and the magnetic chute 33 to ensure the stability of the moving rod 34 in the magnetic chute 33. The electromagnet 35 is a common electromagnetic device in the prior art. By powering the electromagnet 35 to generate magnetism, and the magnetic chute 33 is made of ferromagnetic material, so that magnetic connection is carried out between the electromagnet 35 and the magnetic chute 33. Then the third electric cylinder 30 is started to push the moving box body 29 towards the direction of the concrete plate, so that the two clamping plates 36 are attached to the two included angle areas of the corresponding area of the concrete plate. When the anchor bolts on the concrete plate are subjected to a pull-out test, the concrete plate remains stable. And when the top area of the concrete plate is relatively large, two anchor bolts can be installed at the top of the concrete plate for detection.

By starting the third electric cylinder 30 to drive the moving box body 29 to move, the moving box body 29 and the clamping plates 36 push the concrete plate to move between the two support troughs 38. On the other side, the moving of the concrete plate is kept stable by the pushing plate 43, so that the two anchor bolts at the top of the concrete plate sequentially pass through the press device 1 for longitudinal pull-out tests, and the position of the concrete plate is adjusted so that the two anchor bolts correspond to the two hydraulic drive cylinders 5 at the same time, and the side direction pull-out tests of the two anchor bolts are completed.

[0049] Please refer to Figures 1 to 6 and [[ID=, in this embodiment, a support clamping mechanism 500 is provided on the pushing frame 4.

Then start the fourth electric cylinder 49 to move the pushing plate 43, so that the pushing plate 43 pushes the concrete slab to move between the two support troughs 38, making the concrete slab contact the inner wall of the support trough 38, and clamping the concrete slab between the pushing plate 43 and the two support troughs 38. The elastic support rod 42 can avoid the downward force of the concrete slab from affecting the sliding frame 37 and the two-way screw rod two 48 when the support trough 38 moves downward under the downward force of the concrete slab;

[0050] The flipping drive assembly includes a rotating support 44, a drive shaft 45, and a third drive motor 46. The rotating support 44 is fixedly connected to the pushing frame 4. A drive shaft 45 is rotatably connected within the rotating support 44. A support member is fixedly connected between the drive shaft 45 and the sliding frame 37. The third drive motor 46 is disposed within the pushing frame 4. Tapered gears 47 are provided on both the output end of the third drive motor 46 and the drive shaft 45, and the two tapered gears 47 are meshed. When it is necessary to drive the concrete slab to flip, the third drive motor 46 is started. Through the meshing effect of the two tapered gears 47, the drive shaft 45 is driven to rotate, causing the sliding frame 37 and the two support troughs 38 to flip upward along the center point of the drive shaft 45, flipping the concrete slab upward, so that the height of the anchor bolts installed on the side wall of the concrete slab is consistent with the height of the hydraulic drive cylinder 5 located on the side. Then, the pushing frame 4 and the installation frame 15 are moved, so that the positions of the anchor bolts installed on the side wall of the concrete slab correspond to the positions of the hydraulic drive cylinders 5 on the side, so that the hydraulic drive cylinders 5, the tensile force detectors 2, and the fixed installation members 7 located on the side cooperate to complete the pull-out test of the anchor bolts.

[0051] The working principle or usage process of this multifunctional comprehensive test platform for anchor bolt experiments is as follows:

[0052] First, according to the volume of the concrete slab, the second drive motor 41 is started to drive the bidirectional screw two 48 to rotate, causing the sliding seats 40, elastic support rods 42, and support frames located on both sides to move, adjusting the distance between the two support troughs 38. The concrete slab is placed between the two support troughs 38. Then, the fourth electric cylinder 49 is started to move the pushing plate 43, so that the pushing plate 43 pushes the concrete slab to move between the two support troughs 38, causing the concrete slab to contact the inner walls of the support troughs 38, and clamping the concrete slab fixedly between the pushing plate 43 and the two support troughs 38;

[0053] Then, the hydraulic drive cylinder 5 is started to drive the installation cylinder 6 to move. After the installation cylinder 6 and the meshing ring 8 move between the two meshing bodies 9, the first electric cylinders 10 located on both sides are started to push the meshing bodies 9 to move, so that the meshing bodies 9 are meshed with the meshing ring 8. Thus, when the hydraulic drive cylinder 5 continues to drive the installation cylinder 6 to move, it can drive the pushing frame 4 and the installation frame 15 to move on the support platform 3, and move the concrete slab to directly below the press device 1;

[0054] Then start the press device 1 to drive the tensile detector 2 to descend, so that the connecting rod 11 drives a plurality of meshing tooth blocks 12 to move between a plurality of receiving tooth grooves 14, and then drives the rotating disk 13 and the plurality of receiving tooth grooves 14 to rotate, so that the meshing tooth blocks 12 move into the corresponding receiving tooth grooves 14, and the meshing tooth blocks 12 are engaged with the meshing tooth grooves. Thus, when the press device 1 drives the connecting rod 11 to reset subsequently, the connecting rod 11 drives the fixed mounting member 7 to conduct a pulling test on the anchor bolt. Through the above method, the hydraulic drive cylinder 5 located on the side can also conduct a lateral pulling test on the anchor bolt after the press device 1 has completed the longitudinal pulling test on the anchor bolt;

[0055] When it is necessary to conduct a pulling test on the anchor bolts on the side of the concrete slab, start the third drive motor 46. Through the meshing effect of two bevel gears 47, drive the drive shaft 45 to rotate, so that the sliding frame 37 and the two support troughs 38 flip upward along the center point of the drive shaft 45, and the concrete slab flips upward. At the same time, start the second electric cylinder 20 to drive the rotating sliding member 21 to slide at the bottom of the flipping support plate 16, thereby pushing the flipping support plate 16 to flip along the center point of the rotating shaft 17 in the mounting frame 15. Thus, when the drive shaft 45 drives the sliding frame 37 and the support trough 38 to flip upward, the flipping support plate 16 supports the bottom of the two support troughs 38, so that the height of the anchor bolts installed on the side wall of the concrete slab is consistent with the height of the hydraulic drive cylinder 5 located on the side. Then move the pushing frame 4 and the mounting frame 15, so that the positions of the anchor bolts installed on the side wall of the concrete slab correspond to the position of the hydraulic drive cylinder 5 on the side. Thus, the hydraulic drive cylinder 5, the tensile detector 2 and the fixed mounting member 7 located on the side cooperate to complete the pulling test on the anchor bolt.
