Description

Technical Field

[0002] Nuclear power anchor bolts are fasteners specifically used in the construction of nuclear power plants, mainly used for fixing heavy equipment and structural components. Through specific designs and materials, they ensure stability and safety in extreme environments such as high temperatures and strong earthquakes, effectively preventing equipment loosening and falling off, and are widely used in the fixing of various equipment and pipeline connections in nuclear power plants.

[0003] As an important component connecting the internal structure of nuclear power facilities, the tensile resistance performance of nuclear power anchor bolts is directly related to the safety and stability of the entire nuclear facility. Therefore, a professional impact testing machine is required to test the tensile resistance performance of nuclear power anchor bolts to meet actual needs. During the detection, an impact testing machine meeting the standards needs to be selected, and specimens need to be prepared according to the standard requirements. The appearance of the specimens is inspected to ensure there are no problems such as cracks, deformations, rust, etc. Then, parameters such as the loading speed and loading amount are selected, and the specimens are tested according to the procedures.

[0004] Due to the high installation accuracy requirements for nuclear power anchor bolts, the position and depth of the anchor bolts need to be precisely controlled. When installing nuclear power anchor bolts on an impact testing machine, the installation accuracy of the anchor bolts also needs to be ensured to ensure the stability and safety of the structure. During the process of installing concrete and nuclear power anchor bolts on the bench of the test rig, the installation is generally carried out by hoisting, making the installation and fixing process relatively cumbersome, difficult to ensure the installation accuracy of the anchor bolts, and thus affecting the test results.

Detailed implementation manners

[0062] 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 of 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.

[0063] Please refer to Figures 1 to 10, An impact test bench, comprising a bottom plate 1, on which a plurality of mounting holes 2 are equidistantly arranged. It further includes a mounting frame 3, a frame assembly, a erection assembly and a test assembly. The mounting frame 3 is arranged on the bottom plate 1, and the frame assembly is mounted on the mounting frame 3 for bearing and fixing the relative position between the bottom plate 1 and the mounting frame 3. The frame assembly includes a bearing frame 4, fixing holes 5 and mounting bolts 6. The bearing frame 4 is fixedly mounted on the top of the mounting frame 3. A plurality of fixing holes 5 are equidistantly arranged at the bottom of the mounting frame 3. An installation bolt 6 is arranged inside each fixing hole 5, and the installation bolt 6 matches the size of the mounting hole 2.

[0064] Specifically, when testing the nuclear power anchor bolt 28, it is necessary to first install the impact test bench. First, place the mounting frame 3 on the bottom plate 1, adjust the position of the mounting frame 3 so that the lower parts of the plurality of fixing holes 5 at the bottom of the mounting frame 3 correspond to the mounting holes 2 on one bottom plate 1 respectively. Then, through the setting of the mounting bolts 6, pass the mounting bolts 6 through the fixing holes 5 and the mounting holes 2, so as to fix the relative position between the bottom plate 1 and the mounting frame 3, and thus fix the relative position of the bearing frame 4. After the installation is completed, the nuclear power anchor bolt 28 to be tested needs to be installed at the test position. At this time, first prepare the concrete block 18 required for the test, place the erection assembly on the concrete block 18 first, install the nuclear power anchor bolt 28 to be tested on the concrete block 18, and then adopt the hoisting method to move the erection assembly to the top of the bearing frame 4 and fix the position of the erection assembly at the top of the bearing frame 4, then the test can be started. During the test, through the setting of the test assembly, record the force borne by the nuclear power anchor bolt 28 and transmit it to the control device for analysis.

[0065] As Figures 1 to 4 shown, the erection assembly is mounted on the frame assembly for installing the nuclear power anchor bolt 28 to be tested and determining the position of the nuclear power anchor bolt 28. The erection assembly includes an erection plate 7, an assembly frame 8, a guiding part and a positioning part. The erection plate 7 is arranged on the top of the bearing frame 4, the assembly frame 8 is fixedly mounted on the erection plate 7, an assembly groove 9 is arranged at the top of the assembly frame 8, the guiding part is mounted on the bearing frame 4 for guiding the installation position of the erection plate 7, and the positioning part is mounted on the bearing frame 4 for fixing the relative position between the erection plate 7 and the bearing frame 4.

[0066] Specifically, after installing the nuclear power anchor bolt 28 to be tested on the erection plate 7, connect the working end of the hoisting device to the assembly groove 9 on the assembly frame 8, and then use the hoisting device to move the erection plate 7 to the top of the bearing frame 4 through the assembly frame 8, and then slowly move it downward until the concrete block 18 is moved into the bearing frame 4 and the erection plate 7 is connected to the positioning part under the action of the guiding part. At this time, through the setting of the positioning part, fix the relative position between the erection plate 7 and the bearing frame 4.

[0067] The above-mentioned, such as Figure 4 ,Figure 5 As shown in the figure, the guiding part includes a guiding frame 10, an inclined surface 11 and a mounting pad 12. Two guiding frames 10 are symmetrically and fixedly installed on the top of the bearing frame 4. Two inclined surfaces 11 are symmetrically arranged on each of the two guiding frames 10. Each two adjacent inclined surfaces 11 incline towards the outside of the guiding frame 10. Mounting pads 12 are fixedly installed on each of the two guiding frames 10, and the two mounting pads 12 are both in contact with the erection plate 7.

[0068] Specifically, when the erection plate 7 moves towards the bearing frame 4, the two ends of the erection plate 7 are respectively above the two guiding frames 10. At this time, through the action of the two inclined surfaces 11 symmetrically arranged on the two guiding frames 10, a guiding effect is achieved, so that the bottom of the erection plate 7 contacts the mounting pad 12 in the middle of the guiding frame 10. During the movement of the erection plate 7, as Figure 3 Figure 4 shown in the figure, grooves are also opened at both ends of the bottom of the erection plate 7. The two grooves at the bottom of the erection plate 7 are respectively adapted to the guiding frames 10, thereby further improving the installation efficiency and stability.

[0069] It should be added that the mounting pad 12 is slightly higher than the guiding frame 10 between the two inclined surfaces 11. After the bottom of the erection plate 7 contacts the mounting pad 12, the mounting pad 12 is deformed, making the fixation more stable.

[0070] As described above, as Figure 4 、 Figure 5 shown in the figure, the positioning part includes connecting ears 13, positioning holes 14 and positioning bolts 15. Two connecting ears 13 are symmetrically and fixedly installed on the bearing frame 4. Positioning holes 14 are opened on each of the two connecting ears 13. Positioning holes 14 are opened at both ends of the erection plate 7. The positioning holes 14 at both ends of the erection plate 7 respectively correspond to the positioning holes 14 on the two connecting ears 13 one by one. Positioning bolts 15 are arranged in the positioning holes 14 at both ends of the erection plate 7, and the positioning bolts 15 are adapted to the positioning holes 14 on the connecting ears 13.

[0071] Specifically, after the erection plate 7 is placed between the two guiding frames 10, at this time, the positioning holes 14 at both ends of the erection plate 7 respectively correspond to the positioning holes 14 on the two connecting ears 13. Then, through the setting of the positioning bolts 15, the relative position between the erection plate 7 and the connecting ears 13 is fixed, and the relative position of the erection plate 7 on the bearing frame 4 can be fixed.

[0072] As Figures 6 to 9As shown in the figure, the test component is installed on the erection component and is used to test the nuclear power anchor bolt 28 to be detected. The test component includes a connecting frame 16, an anchor bolt hole 17, a concrete block 18, a test part, and an anti-falling connection part. The connecting frame 16 is fixedly installed at the bottom of the erection plate 7. The anchor bolt hole 17 is provided on the connecting frame 16. The concrete block 18 is arranged at the bottom of the anchor bolt hole 17. The test part is installed on the connecting frame 16 and is used to measure the force condition of the detected nuclear power anchor bolt 28. The anti-falling connection part is installed on the connecting frame 16 and is used to connect the concrete block 18.

[0073] Specifically, when installing the nuclear power anchor bolt 28, place the connecting frame 16 at the bottom of the erection plate 7 on the concrete block 18, put the nuclear power anchor bolt 28 to be tested into the anchor bolt hole 17, and install it in the hole pre-drilled in the middle of the concrete block 18 at the bottom. After installing the erection plate 7, the test can be started. During the test, the test part records the tension received by the nuclear power anchor bolt 28 and transmits it to the control device for analysis. During the test, through the setting of the anti-falling connection part, during the test, it is avoided that due to the unqualified nuclear power anchor bolt 28 or inappropriate test parameters set, the nuclear power anchor bolt 28 breaks and the concrete block 18 falls, improving the safety and not affecting the progress of the test at the same time.

[0074] As described above, as Figure 6 shown, the test part includes a test hole 19 and a detection sensor 20. Two test holes 19 are provided on the connecting frame 16. The two test holes 19 are symmetrically arranged relative to the anchor bolt hole 17. Detection sensors 20 are fixedly installed on both test holes 19. The contact part of the detection sensor 20 is connected to the concrete block 18.

[0075] Specifically, when installing the detection sensor 20, first install the detection sensor 20 in the test hole 19, and connect the end of the detection sensor 20 to the concrete block 18, then the force received by the nuclear power anchor bolt 28 can be recorded.

[0076] As described above, as Figure 6 、 Figure 7 shown, the anti-falling connection part includes a connection hole 21, a through hole 22, a connecting rod 23, and a nut 24. Connection holes 21 are provided on both sides of the connecting frame 16. The two connection holes 21 are symmetrically arranged relative to the anchor bolt hole 17. The two connection holes 21 are staggered from the two test holes 19. Two through holes 22 are provided on the concrete block 18. The two through holes 22 correspond to the two connection holes 21 one by one. Connecting rods 23 are arranged inside both through holes 22. Threaded sections are arranged at the tail ends of the two connecting rods 23. The threaded sections are located inside the connection holes 21. Two nuts 24 are threadedly sleeved on the threaded sections of the two connecting rods 23. The two nuts 24 on the connecting rod 23 are respectively located at the upper and lower ends of the connection hole 21. The nut 24 abuts against the connecting frame 16.

[0077] Specifically, after installing the nuclear power anchor bolt 28 to be detected, it is also necessary to install the connecting rod 23. The position of the threaded section at the tail end of the connecting rod 23 passes through the through hole 22. At this time, a nut 24 is screwed onto the threaded section. When the threaded section enters the connection hole 21, another nut 24 is screwed onto the threaded section again, so that two nuts 24 are provided on the threaded section of one connecting rod 23, and the two nuts 24 are respectively located at the upper and lower ends of the connection hole 21, which is convenient for fixing the connecting rod 23 and has an anti-loosening effect at the same time. Repeat the above steps to install the other connecting rod 23.

[0078] It should be added that as Figure 6 shown, the head of the connecting rod 23 is set as a disc shape, and the size of the head of the connecting rod 23 is larger than that of the through hole 22, so as to prevent the concrete block 18 from falling.

[0079] As Figure 10 shown, an impact test bench uses the above-mentioned impact test bench frame, including an impact test equipment main body 25. The output end of the impact test equipment main body 25 is fixedly connected to the bottom plate 1, and further includes a foundation groove 26. The foundation groove 26 is arranged on the ground 27, and the impact test equipment main body 25 is installed in the foundation groove 26.

[0080] Specifically, before testing the nuclear power anchor bolt 28, it is necessary to first install the bottom plate 1 at the working end of the impact test equipment main body 25. After installing the bearing frame 4 and the nuclear power anchor bolt 28 to be detected, start the impact test equipment main body 25, and test the anti-tensile performance of the nuclear power anchor bolt 28 in the longitudinal direction through continuous rapid up and down vibration and impact. The impact test equipment main body 25 is installed in the foundation groove 26 arranged on the ground 27, so as to reduce the impact on the external environment generated during the test.

[0081] The working principle or usage process of this application is as follows:

[0082] Before testing the nuclear power anchor bolt 28, it is necessary to first install the bottom plate 1 at the working end of the impact test equipment main body 25, then place the mounting frame 3 on the bottom plate 1, adjust the position of the mounting frame 3 so that the lower parts of the plurality of fixing holes 5 at the bottom of the mounting frame 3 are all corresponding to the mounting holes 2 on one bottom plate 1, and then through the setting of the mounting bolts 6, pass the mounting bolts 6 through the fixing holes 5 and the mounting holes 2, so as to fix the relative position between the bottom plate 1 and the mounting frame 3, and thus fix the relative position of the bearing frame 4.

[0083] When installing the nuclear power anchor bolt 28, place the connecting frame 16 at the bottom of the erection plate 7 on the concrete block 18, put the nuclear power anchor bolt 28 to be tested into the anchor bolt hole 17, and install it in the pre-drilled hole in the middle of the bottom concrete block 18. After installing the nuclear power anchor bolt 28 to be tested, it is also necessary to install the connecting rod 23. The position of the threaded section at the tail end of the connecting rod 23 passes through the through hole 22. At this time, screw a nut 24 onto the threaded section. When the threaded section enters the connecting hole 21, screw another nut 24 onto the threaded section again so that there are two nuts 24 on the threaded section of one connecting rod 23, and the two nuts 24 are respectively located at the upper and lower ends of the connecting hole 21, which is convenient for fixing the connecting rod 23 and has an anti-loosening effect. Repeat the above steps to install the other connecting rod 23.

[0084] After installing the nuclear power anchor bolt 28 to be tested, connect the working end of the hoisting device to the assembly groove 9 on the assembly frame 8, and then use the hoisting device to move the erection plate 7 to the top of the bearing frame 4 through the assembly frame 8, and then slowly move it downward. When the erection plate 7 moves towards the bearing frame 4, the two ends of the erection plate 7 are respectively above the two guiding frames 10. At this time, through the action of the two inclined surfaces 11 symmetrically arranged on the two guiding frames 10, it plays a guiding role, so that the bottom of the erection plate 7 contacts the mounting pad 12 in the middle of the guiding frame 10. During the movement of the erection plate 7, as Figure 3 Figure 4 shown, grooves are also opened at both ends of the bottom of the erection plate 7. The two grooves at the bottom of the erection plate 7 are respectively adapted to the guiding frames 10, which further improves the installation efficiency and stability.

[0085] After placing the erection plate 7 between the two guiding frames 10, the positioning holes 14 at both ends of the erection plate 7 respectively correspond to the positioning holes 14 on the two connecting ears 13. Then, through the setting of the positioning bolts 15, the relative positions between the erection plate 7 and the connecting ears 13 are fixed, and thus the relative position of the erection plate 7 on the bearing frame 4 can be fixed.

[0086] After installing the erection plate 7, the test can be started. Start the impact test equipment main body 25. Through continuous rapid up and down vibration and impact, test the tensile resistance performance of the nuclear power anchor bolt 28 in the longitudinal direction. The end of the detection sensor 20 is connected to the concrete block 18, and thus the force received by the nuclear power anchor bolt 28 can be recorded. The impact test equipment main body 25 is installed in the foundation groove 26 set on the ground 27, so as to reduce the impact on the external environment generated during the test.

[0087] During the test, due to the provision of the connecting rod 23, the situation where the nuclear power anchor bolt 28 breaks and the concrete block 18 drops caused by the unqualified nuclear power anchor bolt 28 or inappropriate test parameters set is avoided during the test, improving the safety and at the same time not affecting the progress of the test.
