[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] See also Figures 1 to 4A expansion bolt pull-out test frame includes: a frame 1, a pulling block 2, a disassembly and assembly mechanism, a pulling mechanism and a pressing mechanism. The pulling block 2 is fixedly connected to the frame 1, and a tapered opening is opened on the pulling block 2. Through the cooperation between the frame 1, the pulling block 2, the disassembly and assembly mechanism, the pulling mechanism and the pressing mechanism, the expansion bolts can be automatically and quickly installed and disassembled, which saves time and effort and improves the efficiency of the expansion bolt pull-out test.

[0045] Among them, the disassembly and assembly mechanism is arranged on the frame 1, and is used to install and disassemble the expansion bolts. The disassembly and assembly mechanism includes: a lifting block 3, a support plate 4, a disassembly cylinder 5, a first electric cylinder 6 and a rotating assembly. The lifting block 3 is slidingly arranged in the frame 1, and the support plate 4 is fixedly connected to the lifting block 3. The disassembly cylinder 5 is rotatably arranged on the support plate 4. The first electric cylinder 6 is arranged on the frame 1, and the output end of the first electric cylinder 6 is fixedly connected to the lifting block 3. The rotating assembly is arranged on the support plate 4 for driving the disassembly cylinder 5 to rotate. The rotating assembly includes: a rotating gear 7, a driving gear 8 and a first motor 9. The rotating gear 7 is fixedly connected to the disassembly cylinder 5. The gear 8 is rotatably arranged on the support plate 4, the driving gear 8 is engaged with the rotating gear 7, the first motor 9 is arranged on the support plate 4, and the output end of the first motor 9 is fixedly connected to the driving gear 8. Specifically, after the expansion bolt is inserted into the mounting hole, the first electric cylinder 6 arranged on the frame 1 drives the lifting block 3 to descend, so that the disassembly cylinder 5 on the support plate 4 is sleeved on the nut, and then the first motor 9 arranged on the support plate 4 drives the driving gear 8 and the rotating gear to rotate, thereby driving the disassembly cylinder 5 to rotate, thereby tightening the nut. When the nut is tightened, the expansion bolt expands in the tapered mouth and is then fixed in the tapered mouth.

[0046] Among them, the pulling mechanism is arranged on the frame 1, which is used to perform a pulling test on the expansion bolts. The pulling mechanism includes: a pulling frame 10, a tension sensor 11 and a hydraulic cylinder 12. Two sliding rods 16 are fixedly connected to the frame 1, and two sliders 17 are fixedly connected to the pulling frame 10. The two sliders 17 are provided with sliding holes. The two sliding rods 16 are respectively slidably arranged in the two sliding holes. The pulling frame 10 is slidably arranged in the frame 1, and the pulling frame 10 is provided with a mounting hole. The tension sensor 11 is arranged on the pulling frame 10, and the hydraulic cylinder 12 is arranged on the frame 1. The output end of the hydraulic cylinder 12 is fixedly connected to the tension sensor 11. Specifically, it is raised by the hydraulic cylinder 12 arranged on the frame 1. When the hydraulic cylinder 12 rises, it drives the tension sensor 11 and the pulling frame 10 to rise, thereby performing a pulling test on the expansion bolts.

[0047] Among them, the pressing mechanism is arranged on the frame 1, which is used to unload the expansion bolts. The pressing mechanism includes: a fixed plate 13, a lower pressing frame 14 and a second electric cylinder 15. The fixed plate 13 is fixedly connected to the drawing frame 10, the lower pressing frame 14 is arranged on the fixed plate 13, and the second electric cylinder 15 is arranged on the fixed plate 13. The output end of the second electric cylinder 15 passes through the fixed plate 13 and is fixedly connected to the lower pressing frame 14. Specifically, the second electric cylinder 15 arranged on the fixed plate 13 drives the lower pressing frame 14 to descend, thereby ejecting the expansion bolts in the tapered mouth, thereby quickly unloading the expansion bolts.

[0048] In summary, when the expansion bolt pulling test stand is in use, the operator needs to first unscrew the nut on the expansion bolt, then insert the expansion bolt into the tapered mouth and the mounting hole, and then screw on the nut. The first electric cylinder 6 provided on the frame 1 drives the lifting block 3 to descend, so that the disassembly cylinder 5 on the support plate 4 is sleeved on the nut. Then, the first motor 9 provided on the support plate 4 drives the driving gear 8 and the rotating gear to rotate, thereby driving the disassembly cylinder 5 to rotate, thereby tightening the nut. When the nut is tightened, the expansion bolt is tightened in the tapered mouth. The expansion bolt expands and is fixed in the tapered mouth and the mounting hole. The expansion bolt is then raised by the hydraulic cylinder 12 provided on the frame 1. When the hydraulic cylinder 12 rises, the tension sensor 11 and the pulling frame 10 are driven to rise, thereby performing a pulling test on the expansion bolt. After the test is completed, the first motor 9 is rotated in the opposite direction, thereby driving the disassembly barrel to rotate in the opposite direction, thereby removing the nut. The lower pressing frame 14 is then driven to descend by the second electric cylinder 15 provided on the fixing plate 13, thereby ejecting the expansion bolt in the tapered mouth, thereby quickly cutting the expansion bolt.
