[0002] In concrete post-anchoring projects, in order to determine the pull-out performance of anchors under ultimate limit state and serviceability limit state, and to ensure the construction quality of concrete post-anchors and the safe use of related buildings, it is necessary to conduct on-site sampling tests on the pull-out performance of concrete post-anchors.

[0003] Current testing devices are very inconvenient to use. During the testing process, they cannot properly clamp the anchors, resulting in inaccurate data on the tensile bearing capacity of the anchors. Furthermore, the data may be inaccurate when the anchors are stretched manually. In order to address this technical problem, this application proposes an anchor bearing capacity testing device. Utility Model Content

[0004] The present invention provides an anchor bearing capacity testing device that uses the cooperation between bevel gear one and bevel gear two to clamp the anchor bolt inserted into the wall, preventing the anchor bolt from coming off during the stretching process. The clamping device can ensure that the anchor bolt maintains a fixed position and posture during the testing process. Through the cooperation between the motor and rack one, the repeatability of the testing process can be achieved, ensuring that the anchor bolt is placed under the same test conditions even in multiple tests.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anchor bearing capacity testing device, comprising a housing, a sliding column provided on the inner wall of the housing, a rack fixedly connected to the right side of the sliding column, a transmission gear meshing with the upper right end of the rack, a box fixedly connected to the bottom side of the sliding column, a bevel gear rotatably connected to the inner wall of the box, a bevel gear 2 meshing with the bottom right end of the bevel gear 1, a support column fixedly connected to the bottom side of the bevel gear 2, a transmission gear 2 fixedly connected to the bottom end of the bevel gear 2, a rack 3 and a rack 2 meshing with the front and rear ends of the transmission gear 2 respectively, a support plate fixedly connected to the bottom ends of the rack 2 and rack 3 respectively, and a clamping plate fixedly connected to the bottom sides of both support plates.

[0006] Furthermore, a motor is mounted on the rear side of the housing via a support frame, and the drive end of the motor is fixedly connected to the rear side of the transmission gear.

[0007] Furthermore, a handle is fixedly connected to the front side of the bevel gear, and the handle is located on the front side of the housing.

[0008] Furthermore, two support columns are fixedly connected to the bottom side of the shell, and a fixing plate is fixedly connected to the bottom side of each of the two support columns.

[0009] Furthermore, the front side of the transmission gear is rotatably connected to the inner wall of the housing.

[0010] Furthermore, the front side of the first bevel gear and the top side of the second bevel gear are rotatably connected to the inner wall of the housing.

[0011] Furthermore, the sliding column penetrates the inner wall of the shell.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, the anchor bolt inserted into the wall is clamped by the cooperation between bevel gear one and bevel gear two, which prevents the anchor bolt from coming off during the stretching process. The clamping device can ensure that the anchor bolt remains in a fixed position during the test, avoiding test errors caused by the movement or twisting of the anchor bolt.

[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] Reference Figures 1-3In one embodiment of this utility model: a sliding column 10 is provided on the inner wall of the housing 1. A motor 2 controls the rotation of a transmission gear 12, which in turn drives a rack 11 connected to the transmission gear 12 to move up and down. The up-and-down movement of the rack 11 then drives the sliding column 10 connected to the rack 11 to move up and down together, increasing the support force for the up-and-down movement of the housing 3 and improving the pulling force of the bevel gear 13. A rack 11 is fixedly connected to the right side of the sliding column 10. The up-and-down movement of the rack 11 drives the sliding column 10 connected to the rack 11 to move up and down together. The downward movement provides stronger support for the housing 3. The upper right side of the rack-11 is meshed with a transmission gear-12. The motor 2 drives the transmission gear-12 to rotate, and the rotation of the transmission gear-12 drives the rack-11, which meshes with the transmission gear-12, to move up and down. This, in turn, drives the sliding column 10 connected to the rack-11 to move up and down. The bottom side of the sliding column 10 is fixedly connected to the housing 3. The up and down movement of the sliding column 10 drives the up and down movement of the housing 3. The accuracy of the measurement is achieved through the lifting and lowering, ensuring that the anchor bolt is placed under the same test conditions even in multiple tests. This helps to compare test results at different time points or between different anchors to assess anchor performance changes or compare the load-bearing capacity of different anchors. The inner wall of the housing 3 is rotatably connected to a bevel gear 13, which is controlled to rotate via a handle 4. The rotation of bevel gear 13 drives a bevel gear 14 connected to it to rotate as well. The rotation of bevel gear 14 drives a support column 5 connected to its bottom side, which in turn drives a transmission gear 16 connected to its bottom side to rotate. The rotation of transmission gear 16 then drives racks 15 and 17 connected to its front and rear sides to move in opposite directions. This movement of racks 15 and 17 in opposite directions then drives support plates 6 connected to their bottom sides. Moving in opposite directions causes the fixed plate 9 connected to the lower end of the support plate 6 to move in the opposite direction or in the same direction, achieving a clamping effect. The right bottom end of bevel gear 13 is meshed with bevel gear 14, and the bottom side of bevel gear 14 is fixedly connected to support column 5. The bottom end of bevel gear 14 is fixedly connected to transmission gear 16, and the front and rear ends of transmission gear 16 are respectively meshed with rack 3 15 and rack 2 17. The bottom ends of rack 2 17 and rack 3 15 are respectively fixedly connected to support plate 6, and the bottom sides of both support plates 6 are fixedly connected to clamping plates 7, thus causing the fixed plate 9 connected to the lower end of the support plate 6 to move in opposite directions or in the same direction, achieving a clamping effect. Clamping ensures that the anchor bolt maintains a fixed position and posture during testing, avoiding test errors caused by anchor bolt movement or twisting. This stability helps to obtain accurate load-bearing capacity test results.

[0023] Reference Figures 2-4 A motor 2 is mounted on the rear side of the housing 1 via a support frame. The drive end of the motor 2 is fixedly connected to the rear side of the transmission gear 12. The motor 2 controls the lifting and lowering of the housing 3 more precisely and also saves labor costs. A handle 4 is fixedly connected to the front side of the bevel gear 13. The handle 4 is located on the front side of the housing 3. Two support columns 8 are fixedly connected to the bottom side of the housing 1. A fixing plate 9 is fixedly connected to the bottom side of each of the two support columns 8. The front side of the transmission gear 12 is rotatably connected to the inner wall of the housing 1. The front side of the bevel gear 13 and the top side of the bevel gear 14 are rotatably connected to the inner wall of the housing 3. The sliding column 10 penetrates the inner wall of the housing 1.

[0024] Working principle: First, the handle 4 controls the rotation of bevel gear 13, which in turn drives bevel gear 14, which meshes with bevel gear 13, to rotate. The rotation of bevel gear 14 then drives the transmission gear 16, connected to its bottom side via a rotating column, to rotate as well. The rotation of transmission gear 16 causes racks 15 and 17, meshing before and after it, to move in opposite directions. This movement of racks 15 and 17 in opposite directions causes the support plate 6 connecting their bottom sides to move in opposite directions. As racks 15 and 17 move in opposite directions, the support column 5 limits their movement, preventing them from colliding. When rack 15 and rack 2 17 move, they wobble back and forth, which causes the clamping plate 7 connected to the bottom side of the support plate 6 to clamp the structure being tested, preventing the object being tested from swaying left and right. Then, the motor 2 controls the rotation of the transmission gear 12, which drives the rack 11 meshing with the transmission gear 12. Since the left side of the rack 11 is connected to the sliding column 10, the motor 2 can drive the rack 11 to move up and down while controlling the rotation of the transmission gear 12, thereby realizing the lifting and lowering of the sliding column 10. The bottom side of the sliding column 10 is connected to the housing 3. The lifting and lowering of the sliding column 10 drives the lifting and lowering of the housing 3. The control of the motor 2 can improve the accuracy of the test support force.
