Description

Technical Field

[0001] This utility model relates to the field of anchor bolt support technology, and more specifically, to a support device for anchor bolt static load testing. Background Technology

[0002] With the continuous development of infrastructure construction in my country, the design and construction of various cross-river and cross-sea bridges are emerging in large numbers, including bridges with a design service life of over a century and / or large tonnage design loads. Along with changes in the bridge's application environment and the requirements for its service life, higher demands are placed on the design schemes and component performance during the bridge design and construction process. In the construction of bridges, especially cable-stayed bridges, the application of anchor bolts is widespread, playing a crucial role in the stability of the bridge's load-bearing capacity and its service life. As the design service life and / or tonnage design load of bridges increase, the requirements for high-strength anchor bolts used to connect the bridge's steel beams and concrete tower columns become even higher, necessitating continuous increases in the strength and size of the anchor bolts. To ensure that the static mechanical properties of the anchor bolts meet the needs of design and practical application, static mechanical performance tests are required before the actual application of the anchor bolts.

[0003] Among them, the patent with announcement number CN217520908U discloses a static load test device for anchor bolt pullout resistance, including an anchor bolt body and an anchor plate. The anchor bolt body is sleeved inside the center of the anchor plate. A jack is provided on the top side of the anchor plate, and a clamp is provided on the top side of the jack. A clamping piece is snapped into the inside of the clamp, and a sleeve is movably connected to the outer side of the end of the anchor bolt body near the clamping piece.

[0004] When in use, this structure uses four sets of limiting plates inserted into the corresponding four sets of slots to limit the clamp to the top of the protruding end, thus ensuring that the jack and the clamp are coaxial. At the same time, the bottom end of the sleeve abuts against the top of the top plate. However, when using this structure to clamp the workpiece with the jack and clamp, it is not easy to quickly disassemble and install the workpiece, making it inconvenient to perform static load tests on the workpiece. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a support device for anchor bolt static load test, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a support device for static load testing of anchor bolts, including a base, on which a support component is provided;

[0007] The support assembly includes a connecting plate disposed on the top of the base, an adjusting plate for lifting is disposed on the top of the connecting plate, and a first positioning cylinder for positioning the workpiece is embedded in the adjusting plate.

[0008] A pressure plate is provided on the top of the first positioning cylinder, and a second positioning cylinder for positioning the workpiece is embedded in the pressure plate. A spring is provided between the second positioning cylinder and the first positioning cylinder. A vertical plate is provided on the outside of the connecting plate. The vertical plate is installed on the base by bolts. A rotating shaft is rotatably connected to the vertical plate. The rotating shaft is placed horizontally on the top of the second positioning cylinder. An eccentric plate is installed on the rotating shaft through a flange. The eccentric plate is located on the top of the second positioning cylinder.

[0009] As can be seen, in the above technical solution, the first positioning cylinder and the adjusting plate can be adjusted up and down on the top of the connecting plate along the guide rod, so as to realize the function of adjusting the position of the adjusting plate, the function of adjusting the length of the spring tension, and can also adapt to anchor rods of different lengths. Furthermore, the anchor rod is limited by the second positioning cylinder and the first positioning cylinder, which makes it easy to disassemble and install the anchor rod and improves the convenience of the experiment.

[0010] Optionally, in one possible implementation, two guide rods are slidably connected to the adjustment plate, and each guide rod is fixed to the connecting plate. Both guide rods are threaded with nuts located at the bottom of the adjustment plate. A motor for driving the rotating shaft to rotate is installed on one side of the top of the upright plate by bolts.

[0011] As can be seen, in the above technical solution, the rotating shaft is driven by a motor to rotate. When the rotating shaft rotates, it drives the eccentric disk to rotate along the axial direction of the rotating shaft, so that the eccentric disk can abut against the top of the second positioning cylinder. This allows the second positioning cylinder and the pressure plate to move downward, thereby realizing the function of performing a pressure test on the anchor rod. The eccentric setting of the eccentric disk is to facilitate the adjustment of the pressure applied to the second positioning cylinder by the rotation of the eccentric disk.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] By setting up support components and adjusting the position of the adjustment plate, the function of adjusting the length of the spring extension can be realized. It can also adapt to anchor rods of different lengths. Furthermore, the anchor rod is limited by the second positioning cylinder and the first positioning cylinder, making it easy to disassemble and install the anchor rod and improving the convenience of the experiment.

[0014] The motor drives the rotating shaft to rotate, which in turn drives the eccentric disk to rotate along the shaft's axis. This allows the eccentric disk to abut against the top of the second positioning cylinder, thereby enabling the second positioning cylinder and the pressure plate to move downwards. This achieves the function of performing a pressure test on the anchor rod. The eccentric setting of the eccentric disk allows for adjustment of the pressure applied to the second positioning cylinder by the rotation of the eccentric disk. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] As attached Figures 1-4 The support device shown is for static load testing of anchor bolts. Through the support components on the base 1, and by adjusting the extension length of the spring 7, it can accommodate anchor bolts of different lengths. The second positioning cylinder 6 and the first positioning cylinder 4 limit the anchor bolt's position, facilitating easy disassembly and installation and improving the convenience of the experiment. The motor 12 drives the rotating shaft 9 to rotate, causing the eccentric disk 10 to rotate along the axial direction of the shaft 9. This allows the eccentric disk 10 to abut against the top of the second positioning cylinder 6, thereby causing the second positioning cylinder 6 and the pressure plate 5 to move downwards, achieving the function of applying pressure to the anchor bolt. The eccentric setting of the eccentric disk 10 allows for adjustment of the pressure applied to the second positioning cylinder 6 by the rotation of the eccentric disk 10. The specific structural configuration of the components is as follows.

[0023] The support assembly includes a connecting plate 2 disposed on the top of the base 1, an adjusting plate 3 for lifting is disposed on the top of the connecting plate 2, and a first positioning cylinder 4 for positioning the workpiece is embedded in the adjusting plate 3.

[0024] A pressure plate 5 is provided on the top of the first positioning cylinder 4. A second positioning cylinder 6 for positioning the workpiece is embedded in the pressure plate 5. A spring 7 is provided between the second positioning cylinder 6 and the first positioning cylinder 4. A vertical plate 8 is provided on the outside of the connecting plate 2. The vertical plate 8 is installed on the base 1 by bolts. A rotating shaft 9 is rotatably connected to the vertical plate 8. The rotating shaft 9 is horizontally placed on the top of the second positioning cylinder 6. An eccentric plate 10 is installed on the rotating shaft 9 through a flange. The eccentric plate 10 is located on the top of the second positioning cylinder 6.

[0025] Two guide rods 11 are slidably connected to the adjusting plate 3, and each guide rod 11 is fixed on the connecting plate 2. Both guide rods 11 are threaded with nuts located at the bottom of the adjusting plate 3. A motor 12 for driving the rotating shaft 9 to rotate is installed on one side of the top of the upright plate 8 by bolts.

[0026] The specific working principle is as follows: When conducting a static load test on the anchor rod, the anchor rod is placed between the first positioning cylinder 4 and the second positioning cylinder 6. Then, by rotating the nut at the bottom of the adjusting plate 3, the first positioning cylinder 4 and the adjusting plate 3 can be adjusted up and down along the guide rod 11 at the top of the connecting plate 2, thereby realizing the function of adjusting the position of the adjusting plate 3 and adjusting the extension length of the spring 7. It can also adapt to anchor rods of different lengths. Furthermore, the anchor rod is limited by the second positioning cylinder 6 and the first positioning cylinder 4, making it easy to disassemble and install the anchor rod and improving the convenience of the test.

[0027] The rotating shaft 9 is driven to rotate by the motor 12. When the rotating shaft 9 rotates, it drives the eccentric disk 10 to rotate along the axial direction of the rotating shaft 9, so that the eccentric disk 10 can abut against the top of the second positioning cylinder 6, thereby allowing the second positioning cylinder 6 and the pressure plate 5 to move downward, realizing the function of pressurizing the anchor rod. The eccentric setting of the eccentric disk 10 is to adjust the pressure applied to the second positioning cylinder 6 by the rotation of the eccentric disk 10.

[0028] Unlike existing technologies, this application discloses a support device for anchor bolt static load testing. By adjusting the extension length of the spring 7, it can accommodate anchor bolts of different lengths. Furthermore, the anchor bolt is limited by the second positioning cylinder 6 and the first positioning cylinder 4, facilitating anchor bolt disassembly and installation and improving the convenience of the experiment. The rotating shaft 9 is driven to rotate by the motor 12. When the rotating shaft 9 rotates, it drives the eccentric disk 10 to rotate along the axial direction of the rotating shaft 9, so that the eccentric disk 10 can abut against the top of the second positioning cylinder 6. This allows the second positioning cylinder 6 and the pressure plate 5 to move downward, realizing the function of applying pressure to the anchor bolt. The eccentric setting of the eccentric disk 10 allows for adjustment of the pressure applied to the second positioning cylinder 6 by the rotation of the eccentric disk 10.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
