Description

Technical Field

[0001] This invention belongs to the technical field of anchor bolt tension testing equipment, specifically relating to an automated anchor bolt tension testing device. Background Technology

[0002] Tension testing is a necessary procedure that anchor bolt products must undergo before leaving the factory, and it is an important way to test the mechanical properties of anchor bolts.

[0003] Current tensioning tests primarily employ a whole-unit tensioning method. This involves manually installing the ferrule at both ends of the anchor bolt using the threaded connection between the anchor bolt and the ferrule, then lifting the anchor bolt into the clamp of the tensioning equipment. The equipment applies tension force to the entire anchor bolt to complete the test. After the test, the ferrule must be manually removed. Due to the significant weight of the anchor bolt, manual lifting and unloading are inconvenient.

[0004] A prior art Chinese patent with authorization announcement number CN205708412U discloses an automatic loading and unloading mechanism for wind turbine anchor bolt tensioning. This mechanism includes an loading frame and an unloading frame, with a V-shaped support plate positioned between them. The V-shaped support plate is vertically mounted above the tensioning equipment. An inclined loading plate is mounted on the loading frame, and an inclined transition plate is located on the right side of the loading plate. The right side of the transition plate connects to the V-shaped support plate. A space is provided between the loading plate and the transition plate for... The anchor bolts rolling off the loading plate are lifted to the loading cylinder on the transition plate. A positioning cylinder is located below the transition plate, and a positioning baffle is located at the top of the positioning cylinder. When the positioning baffle extends, it stops the anchor bolt, allowing the operator to manually install the clamp onto the anchor bolt. When the positioning baffle descends, it avoids the anchor bolt, allowing the anchor bolt to continue rolling down onto the V-shaped support plate. The V-shaped support plate descends and places the anchor bolt in the tensioning equipment. After the tensioning test is completed, the V-shaped support plate rises, lifting the anchor bolt out of the tensioning equipment and placing it on the unloading plate on the unloading rack.

[0005] Although the aforementioned patent enables automatic loading and unloading of anchor bolts, it still requires manual installation of clamps at both ends of each anchor bolt, which is cumbersome and inefficient. Summary of the Invention

[0006] The purpose of this invention is to provide an automated tensioning test device for anchor bolts, so as to solve the technical problem of low test efficiency caused by manual installation of clamps in the prior art.

[0007] To achieve the above objectives, the technical solution of the automated anchor bolt testing equipment provided by the present invention is as follows: An automated anchor bolt testing equipment includes a tensioning device for performing tension tests on anchor bolts equipped with ferrules. A loading rack and a unloading rack are respectively provided on both sides of the tensioning device. The loading rack is provided with a first clamping structure for clamping the anchor bolt. The automated anchor bolt tensioning testing equipment also includes a ferrule mounting frame located beside the loading rack. The ferrule mounting frame is provided with a first ferrule support structure for supporting the ferrule. The first ferrule support structure has a first active roller extending along the tensioning direction of the anchor bolt. The first active roller drives the ferrule to rotate by friction. The ferrule mounting frame is also provided with a pushing device for pushing the ferrule supported on the first ferrule support structure toward the anchor bolt.

[0008] The beneficial effects are as follows: Compared with the manual installation of the ferrule in the prior art, the automated tensioning test equipment for anchor bolts provided by the present invention can push the ferrule towards the anchor bolt by means of a jacking device, so that a pre-installation force is generated between the ferrule and the anchor bolt. When the first active roller on the ferrule mounting frame rotates, the ferrule is driven to rotate by the friction between the first active roller and the ferrule, so that the ferrule is screwed onto the anchor bolt. No manual operation is required, the operation is simple, and the efficiency is improved.

[0009] As a further improvement, the unloading rack is provided with a second clamping structure for clamping the anchor bolt. The automated anchor bolt tensioning test equipment also includes a ferrule disassembly rack located next to the unloading rack. The ferrule disassembly rack is provided with a second ferrule support structure for supporting the ferrule. The second ferrule support structure has a second active roller that extends along the tensioning direction of the anchor bolt. The second active roller drives the ferrule to rotate by friction.

[0010] The beneficial effect is that when the second active roller on the ferrule removal frame rotates, the ferrule is driven to rotate by the friction between the second active roller and the ferrule, so as to remove the ferrule from the anchor bolt without manual operation, thereby realizing the automatic installation and removal of the ferrule and further improving efficiency.

[0011] As a further improvement, a ferrule mounting bracket and a ferrule disassembly bracket are provided with a ferrule recovery track. The ferrule recovery track extends along the loading and unloading direction of the anchor bolt to recover the ferrules on the ferrule disassembly bracket to the ferrule mounting bracket. The ferrule disassembly bracket is also provided with a pulling device for pulling the ferrules removed from the anchor bolt to the ferrule recovery track.

[0012] The beneficial effect is that the ferrule recycling track can transport the ferrules removed from the anchor bolts to the ferrule mounting frame, realizing the recycling of the ferrules.

[0013] As a further improvement, the pulling device includes a second telescopic device and a second magnetic suction member disposed at the drive end of the second telescopic device, the second magnetic suction member being used to magnetically suction the sleeve to pull the sleeve.

[0014] The beneficial effect is that the magnetic ferrule at the end of the traction arm attracts the ferrule, which in turn drives the ferrule to retract, making manufacturing easier.

[0015] As a further improvement, the second magnetic chuck is a disc structure, and the second magnetic chuck is rotatably assembled at the drive end of the second telescopic device.

[0016] The beneficial effect is that the magnetic suction component is rotatably assembled at the drive end of the second telescopic device, so that the second magnetic suction component can rotate with the ferrule, thus avoiding interference between the second telescopic device and the ferrule.

[0017] As a further improvement, a buffer pad is provided on the side of the second magnetic chuck facing the anchor bolt.

[0018] The beneficial effect is that the buffer pad provides a retraction allowance for the ferrule, so that the spacing between the second magnetic element and the anchor bolt is adapted to the size of the ferrule, so that the ferrule can be attracted by the second magnetic element as soon as it is removed from the anchor bolt.

[0019] As a further improvement, the first ferrule support structure is formed by at least two parallel first rollers, at least one of which is the first active roller.

[0020] The beneficial effect is that the first ferrule support structure formed by the roller can reduce the friction between the ferrule and the first ferrule support structure.

[0021] As a further improvement, the jacking device includes a first telescopic device and a first magnetic suction element disposed at the drive end of the first telescopic device.

[0022] The advantages are: simple structure and easy installation.

[0023] As a further improvement, the second ferrule support structure is formed by at least two parallel second rollers, at least one of which is the second active roller. The length of the second roller closer to the tensioning device is less than the length of the other second rollers to form a ferrule recovery port. The end of the ferrule recovery track near the unloading rack is connected to the ferrule recovery port.

[0024] The beneficial effect is that the end of the ferrule recycling track near the unloading rack is connected to the ferrule recycling port, and the height difference allows the ferrule to roll down automatically, which is convenient for design.

[0025] As a further improvement, the tensioning device is provided with an inclined support rail for the anchor bolts to roll from the upper frame to the lower frame. A stop step is provided between the support rail and the lower frame, and a support cylinder is provided below the stop step to push the anchor bolts on the support rail to the lower frame.

[0026] The beneficial effect is that the stop step between the support guide rail and the unloading frame can buffer the anchor bolts and prevent multiple anchor bolts from rolling down to the second clamping structure at the same time. Attached Figure Description

[0039] The present invention will be further described in detail below with reference to embodiments.

[0040] Example 1 of the automated anchor tensioning test equipment provided in this invention:

[0041] The automatic anchor bolt tensioning test equipment includes a tensioning device 2. The tensioning device 2 is provided with a feeding rack 6 and a discharging rack 9 on both sides. A ferrule mounting rack 14 is provided on the side of the feeding rack 6, and a ferrule disassembly rack 17 is provided on the side of the discharging rack 9. A ferrule recycling track 28 for ferrule 27 to be used cyclically is provided between the ferrule mounting rack 14 and the ferrule disassembly rack 17.

[0042] like Figure 6 As shown, the tensioning device 2 includes a frame extending in the left-right direction. The frame has a rectangular hole extending in the left-right direction, and a mounting ring 3 is provided on the wall of the rectangular hole. A tensioning drive device 4 is also provided on the wall of the hole at the left end of the rectangular hole. Two clamps 5 are provided at the left and right ends of the mounting ring 3, spaced apart. The left clamp 5 is connected to the tensioning drive device 4, and the right clamp 5 is fixed to the frame. Both clamps 5 have tensioning grooves for the sleeves 27 installed on the anchor bolt 1 to fall into. During the test, the two clamps 5 respectively clamp the sleeves 27 at both ends of the anchor bolt 1. The tensioning drive device 4 applies a pulling force to the left clamp 5, so that the clamp 5 applies a tensioning force to the anchor bolt 1 along its length, thus performing a tensioning test on the anchor bolt 1. Four support rails 7 are provided on the frame between the two clamps 5. The four support rails 7 are arranged in pairs, spaced apart at the left and right ends of the frame. The spacing between the support rails 7 in the same group is small, and they are all inclined in the front-back direction. Each support rail 7 consists of two halves arranged at intervals. The front half of the same support rail 7 is connected to the loading frame 6, and the rear end of the rear half of the same support rail 7 is connected to the unloading frame 9. The height of the unloading frame 9 is greater than the height of the support rail 7, so as to form a stop step between the unloading frame 9 and the support rail 7, so as to stop and buffer the anchor bolts. A second top support cylinder 18 is provided below the position where the support rail 7 connects with the unloading frame 9, which is used to push the anchor bolt 1 on the support rail 7 onto the unloading frame 9. An allowance hole is formed at the middle position of the same support guide rail 7 to allow the anchor bolt 1 to fall into the clamp 5. The front end of the front half of the two support guide rails 7 in the same group is rotatably equipped with a rotating shaft 38. An anchor bolt unloading hook 39 is provided on the rotating shaft 38. A first support cylinder 8 is provided on the frame below the allowance hole. The first support cylinder 8 is used to push the anchor bolt 1 in the clamp 5 upward when the tension test is completed. When the rotating shaft 38 rotates, the anchor bolt unloading hook 39 hooks the anchor bolt 1 and guides the anchor bolt 1 to the rear half of the support guide rail 7.

[0043] like Figure 1 and Figure 2 As shown, a feeding rack 6 is provided at each of the left and right ends corresponding to the anchor bolt 1. The two feeding racks 6 have the same structure. The following text will use the feeding rack 6 on the left as an example for introduction. Figure 4As shown, the loading rack 6 is a frame structure, including a first anchor bolt storage section 10 and a first anchor bolt support section 12. The first anchor bolt storage section 10 is located in front of the first anchor bolt support section 12 and is used to place anchor bolts 1 to be tested. The first anchor bolt storage section 10 is higher than the first anchor bolt support section 12. A third supporting cylinder 11 is provided below the position where the first anchor bolt storage section 10 and the first anchor bolt support section 12 meet. The third supporting cylinder 11 is used to support the anchor bolts 1 located in the first anchor bolt storage section 10 onto the first anchor bolt support section 12. The top of the first anchor bolt support section 12 is a slope. A groove is provided at the position where the top slope of the first anchor bolt support section 12 meets the support guide rail 7. A loading anti-rotation seat is detachably installed in the groove. The loading anti-rotation seat has a V-shaped support groove. The size of the V-shaped support groove can be changed according to the diameter of the anchor bolt 1 so that the anchor bolt 1 can be installed. A first clamping cylinder 37 is provided on the front side of the feeding anti-rotation seat. The piston rod of the first clamping cylinder 37 is provided with a push plate at the end, which is used to tighten the anchor bolt 1 when the piston rod extends to prevent the anchor bolt 1 from rotating. The first clamping cylinder 37 and the feeding anti-rotation seat form a first clamping structure. A fourth supporting cylinder 13 is provided on the right side of the feeding anti-rotation seat, which is used to push the anchor bolt 1 with the sleeve 27 installed onto the support guide rail 7.

[0044] The ferrule mounting bracket 14 is located on the left side of the first anchor bolt support 12, such as... Figure 3As shown, the top of the ferrule mounting bracket 14 is provided with a feeding support plate 20. The feeding support plate 20 has two first mounting plates 24 arranged at left-right intervals. Three parallel first rollers are rotatably mounted between the two first mounting plates 24, arranged in an inverted triangle. Below the feeding support plate 20, the feeding rack 6 has a first drive motor. The output shaft of the first drive motor is connected to the bottom roller via a belt to drive the first roller as the first active roller 25 to rotate. This drive roller 25 rotates by relying on the friction between itself and the ferrule 27. The other two first rollers serve as first driven rollers 26. The distances from the axes of the two driven rollers 26 to the axis of the anchor bolt 1 are equal. The distance from the axis of the first active roller 25 to the axis of the anchor bolt 1 is equal to or slightly less than the distance from the axis of the first driven roller 26 to the axis of the anchor bolt 1, allowing the ferrule 27 to be inserted into the space enclosed by the three first rollers. Three first rollers form a first ferrule support structure, which not only supports the ferrule 27, but also drives the ferrule 27 to rotate when the first active roller 25 rotates, so as to install the ferrule 27 on the anchor bolt 1. A pushing device is provided on the left side of the mounting plate on the feeding support plate 20. The pushing device includes a first telescopic device, which is a first telescopic cylinder 21. The piston rod of the first telescopic cylinder 21 forms a pushing arm 22. A first magnetic disk 23 is rotatably mounted on the right end of the piston rod. The first magnetic disk 23 acts as a first magnetic attraction element to attract the ferrule 27 onto the pushing arm 22, so that it moves with the pushing arm 22 when the first telescopic cylinder 21 moves, thereby pushing the rotating ferrule 27 towards the anchor bolt 1. An elastic pad is provided on the side of the first magnetic disk 23 facing the anchor bolt.

[0045] like Figure 1 and Figure 2 As shown, a feeding frame 9 is provided at each of the left and right ends corresponding to the anchor bolt 1. The two feeding frames 9 have the same structure, and the following content will take the feeding frame 9 on the left as an example for introduction. Figure 5 As shown, the unloading rack 9 has an overall frame structure. The unloading rack 9 includes a second anchor bolt support 15 and a second anchor bolt storage 16. The second anchor bolt support 15 is connected to the support guide rail 7, and the second anchor bolt storage 16 is located behind the support of the second anchor bolt 1. A groove is provided at the junction of the second anchor bolt support 15 and the second anchor bolt storage 16. A unloading anti-rotation seat is detachably installed in the groove to prevent the anchor bolt 1 from rotating. A second clamping cylinder 40 is provided on the front side of the unloading anti-rotation seat. The second clamping cylinder 40 and the unloading anti-rotation seat form a second clamping structure. A fifth supporting cylinder 19 is provided on the right side of the second clamping cylinder 40 to push the anchor bolt 1, after the sleeve 27 has been removed, out of the unloading anti-rotation seat. The unloading anti-rotation seat and the second clamping cylinder 40 have the same structure as the loading anti-rotation seat and the first clamping cylinder 37, respectively, and will not be described further.

[0046] The ferrule removal bracket 17 is located on the left side of the second anchor bolt support 15 and the second anchor bolt storage part 16, such as... Figure 3 As shown, the top of the ferrule removal frame 17 is provided with a feeding support plate 29, and the feeding support plate 29 is provided with a ferrule removal structure. The ferrule removal structure includes two second mounting plates 33 arranged at left and right intervals on the feeding support plate 29. Three parallel second rollers are rotatably mounted between the two second mounting plates 33, and the three second rollers are arranged in an inverted triangle. A second drive motor is provided on the feeding frame 9 below the feeding support plate 29. The output shaft of the second drive motor is connected to the bottom roller through a belt to drive the second roller as a second active roller 35 to rotate. The second active roller 35 drives the ferrule 27 to rotate in the opposite direction by relying on the friction between the second active roller 35 and the ferrule 27. The other two second rollers serve as second driven rollers 36. The distances from the axes of the two second driven rollers 36 to the axis of the anchor bolt 1 are equal. The distance from the axis of the second driving roller 35 to the axis of the anchor bolt 1 is equal to or slightly less than the distance from the axis of the second driven roller 36 to the axis of the anchor bolt 1. Together with the second driven rollers 36, they form a space for the sleeve 27 to be inserted. The three second rollers form a second sleeve support structure, which can not only support the sleeve 27, but also drive the sleeve 27 to rotate when the second driving roller 35 rotates, so as to remove the sleeve 27 from the anchor bolt 1.

[0047] A pulling device is provided on the left side of the second mounting plate 33 on the feeding support plate 20. The pulling device includes a second telescopic device. Specifically, the second telescopic device is a second telescopic cylinder 30. The piston rod of the second telescopic cylinder 30 forms a pulling arm 31. The left end of the pulling arm 31 is fixed on the second telescopic cylinder 30. The right end of the pulling arm 31 is rotatably equipped with a second magnetic disk 32. The second magnetic disk 32 acts as a second magnetic attraction element to attract the sleeve 27 onto the pulling arm 31 so that it moves backward with the pulling arm 31 when the second telescopic cylinder 30 moves backward, thereby pulling the sleeve 27 removed from the anchor bolt 1 backward. It should be noted that the second driven roller 36 closer to the tensioning device 2 is shorter. A fixing plate 34 is provided between the two second mounting plates 33. The fixing plate 34 is used to connect the shorter second driven roller 36, forming a gap between the fixing plate 34 and the second mounting plate 33 on the right side. The size of the gap is consistent with the width of the ferrule recovery track 28, serving as a ferrule recovery port for the ferrule 27 removed from the anchor bolt 1 to enter the ferrule recovery track 28. The second disk 32 has an elastic pad on the side facing the anchor bolt 1.

[0048] The ferrule recovery track 28 extends in the front-to-back direction. The rear end of the ferrule recovery track 28 is mounted on the unloading support plate 29 directly opposite the ferrule recovery port, so that the ferrule 27 can enter the ferrule recovery track 28. The front end of the ferrule recovery track 28 is mounted above the first driven roller 26, which is closer to the tensioning device 2, so that the ferrule 27 on the ferrule recovery track 28 can roll onto the second ferrule support structure.

[0049] When conducting the tension test of anchor bolt 1, the feeding rack 6 is first connected to the anchor bolt 1 production line. At least three clamping sleeves 27 are placed in the first clamping sleeve support cavity of the two feeding racks 6. Then, the anchor bolt 1 production line is started, so that the produced anchor bolt 1 products are automatically transported to the first anchor bolt storage part 10 of the feeding rack 6. The third top support cylinder 11 pushes the anchor bolt 1 onto the first anchor bolt support part 12. The anchor bolt 1 located on the first anchor bolt support part 12 will roll down along the top inclined surface of the first anchor bolt support part 12 into the V-shaped support groove of the feeding anti-rotation seat. The first clamping cylinder 37 is activated to press the anchor bolt 1 tightly into the feeding anti-rotation seat. Then, the first drive motor drives the first active roller 25 to drive the clamping sleeve 27 to rotate. At this time, the push arm 22 extends toward the anchor bolt 1 to push the clamping sleeve 27 toward the anchor bolt 1, and then screws the clamping sleeve 27 onto the anchor bolt 1.

[0050] After the ferrule 27 is installed on the anchor bolt 1, the piston rod of the first clamping cylinder 37 retracts, and the fourth supporting cylinder 13 actuates to lift the anchor bolt 1 from the loading anti-rotation seat and guide it onto the support rail 7. Under its own weight, the anchor bolt 1 rolls down the support rail 7 to above the first supporting cylinder 8. Then, the first supporting cylinder 8 descends to below the clamp 5, causing the anchor bolt 1 to enter the clamp 5. The tensioning device 2 is activated to perform a tensioning test on the anchor bolt 1. After the test is completed, the first supporting cylinder 8 lifts the anchor bolt 1 again. At this time, the rotating shaft 38 rotates to drive the ferrule unloading hook 39 to flip. When the ferrule unloading hook 39 rotates, it unloads the anchor bolt 1 onto the support rail 7. The anchor bolt 1 continues to roll along the support rail 7. When it rolls to the end of the support rail 7, the second supporting cylinder 18 pushes the anchor bolt 1 onto the top inclined surface of the first anchor bolt support part 12. 1. Rolling along the inclined plane, when it falls into the unloading anti-rotation seat, the second clamping cylinder 40 presses the anchor bolt 1 tightly into the unloading anti-rotation seat. At this time, the second drive motor starts, causing the second active roller 35 to drive the sleeve 27 to reverse, so as to remove the sleeve 27 from the anchor bolt 1. Then the pulling arm 31 extends and retracts when the sleeve 27 is attracted to the pulling arm 31. Since the second mounting plate 33 is set on the extension stroke of the pulling arm 31, when the pulling arm 31 pulls the sleeve 27 to the position of the second mounting plate 33, the second mounting plate 33 stops the sleeve 27, so that the sleeve 27 is disengaged from the pulling arm 31, and the sleeve 27 is pulled to the sleeve recovery port. Under the action of the second active roller 35, the sleeve 27 rolls from the sleeve recovery port into the sleeve recovery track 28, and rolls down along the sleeve recovery track 28 to the first sleeve support structure for the next installation. After the ferrule 27 is removed from the anchor bolt 1, the piston rod of the second clamping cylinder 40 retracts, and the fifth supporting cylinder 19 pushes the anchor bolt 1 onto the second anchor bolt storage part 16.

[0051] The automated anchor bolt tensioning test equipment provided by this invention has a jacking device that pushes the sleeve 27 toward the anchor bolt 1, so that a pre-installation force is generated between the sleeve 27 and the anchor bolt 1. When the first active roller 25 on the sleeve mounting frame 14 rotates, the sleeve 27 is driven to rotate by the friction between the first active roller 25 and the sleeve 27, so that the sleeve 27 is screwed onto the anchor bolt. When the second active roller 35 on the sleeve removal frame 17 rotates, the sleeve 27 is driven to rotate by the friction between the second active roller 35 and the sleeve 27, so that the sleeve 27 is removed from the anchor bolt 1. The sleeve recycling track 28 between the sleeve mounting frame 14 and the sleeve removal frame 17 can also realize the recycling of the sleeve 27, thereby realizing the automatic installation and removal of the sleeve 27, eliminating the need for manual operation, simplifying operation, and improving efficiency.
