Description

Technical Field

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

[0002] The tensile testing of seismic bracing directly verifies its load-bearing capacity and connection strength, ensuring that it does not slip or break under extreme loads such as earthquakes, preventing the building structure from collapsing due to bracing failure, and minimizing casualties and property losses.

[0003] In existing technologies, when performing tensile testing on seismic bracing, the lower end of the seismic bracing is typically pulled directly by a drive frame, and the tensile force and movement distance of the seismic bracing are detected by force sensors and displacement sensors, thereby testing the tensile strength of the seismic bracing. However, this method has some problems in use. The drive frame can only stretch and test one position of the seismic bracing. When the seismic bracing is large, it is impossible to know the tensile strength of other positions of the seismic bracing, thus failing to guarantee the quality of the seismic bracing. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a tensile strength testing device for seismic bracing.

[0005] The technical solution of this utility model to achieve the above objectives is a seismic bracing tensile testing device, including a workbench, a holding plate above the workbench, the holding plate being installed on the workbench by multiple fixing rods, the seismic bracing being installed on the holding plate by bolts, a multi-point testing mechanism being installed on the workbench, and a marking mechanism being installed on the workbench.

[0006] The multi-point detection mechanism includes a telescopic frame installed on the workbench. One end of the telescopic frame is connected to the lower end of the seismic support. Multiple telescopic rods are provided above the telescopic frame. Guide cylinders are fitted on the outside of the telescopic rods. The guide cylinders are installed on the workbench through support rods. One end of the telescopic rod rests on the seismic support.

[0007] The marking mechanism includes a marker pen installed at one end of a telescopic rod, marking plates on both sides above the workbench, and push frames installed on both sides of the upper part of the workbench, with the telescopic ends of the push frames connected to the marking plates.

[0008] Furthermore, the telescopic frame includes an electric actuator mounted on the workbench. A tension sensor is installed at the telescopic end of the electric actuator, a displacement sensor is installed at one end of the tension sensor, and a connecting rod is installed at one end of the displacement sensor. One end of the connecting rod is connected to the lower end of the seismic support by bolts.

[0009] Furthermore, the telescopic rod has multiple guide grooves, and multiple guide wheels are installed inside the guide cylinder, with one end of each guide wheel extending into the guide groove.

[0010] Furthermore, the pusher includes a fixed plate mounted on the workbench, a movable plate on one side of the fixed plate, the movable plate and the fixed plate being connected by multiple telescopic cylinders, the movable plate and the marking plate being connected by multiple telescopic springs, multiple guide rods being mounted on the marking plate, and multiple guide holes being opened on the movable plate, with one end of each guide rod passing through the guide hole and extending to one side of the movable plate.

[0011] Furthermore, a reset plate is provided above the workbench, the reset plate is located behind multiple telescopic rods, and an electric push rod is installed on the workbench, the telescopic end of the electric push rod is connected to the reset plate.

[0012] The beneficial effects of this utility model are as follows: the lower end of the seismic bracing can be stretched and inspected by the telescopic frame.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] This utility model provides, for example Figure 1-4 The seismic bracing tensile strength testing device shown includes a workbench 1, a holding plate 2 on top of the workbench 1, the holding plate 2 being mounted on the workbench 1 by multiple fixing rods 3, the seismic bracing being mounted on the holding plate 2 by bolts, a multi-point testing mechanism and a marking mechanism being mounted on the workbench 1; the multi-point testing mechanism includes a telescopic frame 4 mounted on the workbench 1, one end of the telescopic frame 4 being connected to the lower end of the seismic bracing, multiple telescopic rods 5 being mounted above the telescopic frame 4, guide cylinders 6 being fitted on the outer side of the telescopic rods 5, the guide cylinders 6 being mounted on the workbench 1 by support rods 7, and one end of the telescopic rods 5 resting against the seismic bracing; the marking mechanism includes a marker pen 8 mounted on one end of the telescopic rods 5, marking plates 9 being provided on both sides above the workbench 1, and push frames 10 being mounted on both sides of the upper end of the workbench 1, the telescopic ends of the push frames 10 being connected to the marking plates 9;

[0021] The process of this device for testing seismic bracing is as follows: The seismic bracing is installed at the lower end of the holding plate 2. One end of the telescopic frame 4 is connected to the lower end of the seismic bracing. The lower end of the seismic bracing is stretched to one side by the telescopic frame 4, causing the seismic bracing to deform. The seismic bracing can push the telescopic rod 5 to one side. The guide cylinder 6 can ensure the direction of movement of the telescopic rod 5. Then, the marking plate 9 is pushed close to the marker pen 8 by the pusher 10, so that the marker pen 8 leaves a mark on the marking plate 9, which can indicate the deformation of the seismic bracing at various positions. Then, the marking plate 9 is pulled back to its original position by the pusher 10. Then, the tension of the telescopic frame 4 is changed, which can cause the seismic bracing to deform again. The above process is repeated, and marking can be done again. After repeated multiple times, multiple marks can be left on the marking plate 9. By observing the position of the marks, the staff can easily know the deformation of the seismic bracing at various positions under different tensions, making the testing of the seismic bracing more comprehensive and ensuring the quality of the seismic bracing.

[0022] Refer to the instruction manual appendix Figure 4 The telescopic frame 4 includes an electric actuator 11 installed on the workbench 1. A tension sensor 12 is installed at the telescopic end of the electric actuator 11. A displacement sensor 13 is installed at one end of the tension sensor 12. A connecting rod 14 is installed at one end of the displacement sensor 13. One end of the connecting rod 14 is connected to the lower end of the seismic support by bolts.

[0023] The process of the telescopic frame 4 stretching the seismic support is as follows: connect one end of the connecting rod 14 to the lower end of the seismic support, and then start the electric actuator 11 to shorten it, which can pull the seismic support to one side. The tension sensor 12 can detect the magnitude of the tension, and the displacement sensor 13 can detect the deformation of the seismic support.

[0024] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 4 The telescopic rod 5 has multiple guide grooves 15, and multiple guide wheels 16 are installed inside the guide cylinder 6. One end of the guide wheel 16 extends into the guide groove 15. The guide wheel 16 and the guide groove 15 can ensure the direction of movement of the telescopic rod 5, and the guide wheel 16 can also reduce the friction when the telescopic rod 5 moves.

[0025] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 3 The pusher frame 10 includes a fixed plate 17 mounted on the workbench 1. A movable plate 18 is provided on one side of the fixed plate 17. The movable plate 18 and the fixed plate 17 are connected by multiple telescopic cylinders 19. The movable plate 18 and the marking plate 9 are connected by multiple telescopic springs 20. Multiple guide rods 21 are mounted on the marking plate 9. Multiple guide holes 22 are opened on the movable plate 18. One end of the guide rod 21 passes through the guide hole 22 and extends to one side of the movable plate 18.

[0026] The process of the pusher 10 pushing the marking plate 9 is as follows: the telescopic cylinder 19 is extended, which pushes the moving plate 18 and the marking plate 9 closer to the marker pen 8. When the marking plate 9 contacts the marker pen 8, the telescopic spring 20 is compressed, which prevents the marking plate 9 from pushing the marker pen 8 to one side while leaving a mark, thus ensuring the detection accuracy. After marking is completed, the telescopic cylinder 19 is shortened, which moves the marking plate 9 away from the marker pen 8, thus preventing useless marking.

[0027] Refer to the instruction manual appendix Figure 4 A reset plate 23 is provided above the workbench 1. The reset plate 23 is located behind multiple telescopic rods 5. An electric push rod 24 is installed on the workbench 1. The telescopic end of the electric push rod 24 is connected to the reset plate 23. After the seismic bracing is inspected, the electric push rod 24 is activated to extend. The electric push rod 24 can push the reset plate 23 to one side, and the reset plate 23 can push the telescopic rods 5 back to their original positions for easy inspection next time.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
