Description

Technical Field

[0001] This utility model relates to the technical field of seismic bracing testing equipment, and more specifically, to a deformation testing fixture for seismic bracing steel. Background Technology

[0002] Seismic bracing includes components such as steel profiles, lead screws, hinges, and pipe clamps. Among these, steel profiles are the main seismic-resistant components, and their strength is closely related to the seismic resistance of the seismic bracing. To ensure the strength of the seismic bracing, the seismic resistance of the steel profiles needs to be tested. Generally, when testing the steel profiles, they need to be repeatedly shaken. During this process, if the strength of the steel profiles is insufficient, deformation may occur, and it is necessary to test whether the steel profiles have deformed. Utility Model Content

[0003] The purpose of this invention is to solve the problem of inconvenient detection after steel deformation, and to design a deformation detection fixture for seismic bracing steel.

[0004] To achieve the above objectives, the technical solution of this utility model is a deformation detection fixture for seismic bracing steel, comprising a workbench, the workbench being mounted on the ground via multiple support legs, a steel body being placed on the workbench, the steel body having multiple elongated holes, multiple detection cylinders being detachably connected to the steel body, the multiple detection cylinders being concentrically corresponding, a pusher frame being mounted above the workbench, a detection rod being provided above the workbench, the pusher frame being able to drive the detection rod to move, the detection rod being able to pass through the inside of the detection cylinder, and a support frame being mounted on the workbench, the support frame being able to support the detection rod.

[0005] Furthermore, a limiting groove is opened at the upper end of the worktable, the steel body is placed in the limiting groove, a square through hole is opened in the middle of the limiting groove, a fixing plate is installed at the lower end of the detection cylinder, and connecting holes are opened at both ends of the fixing plate. The connecting holes and the oblong holes on the fixing plate are connected by bolts.

[0006] Furthermore, movable plates are provided on both sides of the limiting groove, an electric telescopic rod is installed on one side surface of the movable plate, the fixed end of the electric telescopic rod is installed on the workbench, and multiple rotating rollers are installed on the inner surface of the movable plate.

[0007] Furthermore, the pusher includes a support frame mounted on one side of the upper surface of the worktable, with two feed wheels rotatably mounted inside the support frame. The detection rod can pass through the two feed wheels. A servo motor is mounted on one side of the upper surface of the worktable, and the rotating end of the servo motor is connected to one of the feed wheels.

[0008] Furthermore, the support frame includes a support sleeve located above the workbench. The support sleeve is mounted on the workbench via multiple fixing rods. One end of the detection rod is located inside the support sleeve. The support sleeve is located behind the feed wheel. Multiple holding racks are provided in front of the feed wheel. Two rotatable support rollers are installed inside the holding racks. The detection rod can pass through the inside of the support rollers. The holding racks can enter the interior of the steel body. The two sides of the support frame are mounted on the workbench via support rods.

[0009] The beneficial effects of this utility model are as follows: Before conducting a seismic test on the steel profile, the testing cylinder is first installed on the steel profile, and then the testing rod is passed through the testing cylinder by a pushing frame. After that, the steel profile is removed. After conducting the seismic test, the steel profile is installed on the workbench, and the testing rod is moved again by the pushing frame. If the testing rod can pass through multiple testing cylinders, it indicates that the deformation of the steel profile is not significant and it is a qualified product. If the testing rod cannot pass through multiple testing cylinders, it indicates that the deformation of the steel profile is significant and it is a defective product. This makes it easier to judge the quality of the steel profile. Attached Figure Description

The multiple detection cylinders 5 are concentrically corresponding. A pusher frame 6 is installed above the workbench 1. A detection rod 7 is provided above the workbench 1. The pusher frame 6 can drive the detection rod 7 to move. The detection rod 7 can pass through the inside of the detection cylinder 5. A support frame 8 is installed on the workbench 1 to support the detection rod 7.

[0018] The process of this device for inspecting the steel profile body 1 is as follows: First, the inspection cylinder 5 is installed on the steel profile body 3. Then, the steel profile body 3 is placed on the workbench 1. The inspection rod 7 is moved by the push frame 6 and passes through the inspection cylinder 5.

After the test is completed, the steel profile body 3 is placed in the same position on the workbench 1 again. The inspection rod 7 is moved by the push frame 6. If the inspection rod 7 can pass through multiple inspection cylinders 5, it indicates that the deformation of the steel profile body 3 is not large and it is a qualified product. If the inspection rod 7 cannot pass through multiple inspection cylinders 5, it indicates that the deformation of the steel profile body 1 is large and it is a defective product. This makes it easier to judge the quality of the steel profile body.

[0020] The process of connecting the detection cylinder 5 to the steel body 3 is as follows: Place the steel body 3 into the limiting groove 9, and make the elongated hole 4 above the square through hole 10. Then place the fixing plate 11 inside the steel body 3, and install the fixing plate 11 and the detection cylinder 5 on the steel body 3 by bolt connection.
