Description

Technical Field

[0001] This utility model relates to the field of building engineering testing technology, and in particular to a tensile testing device for building engineering testing. Background Technology

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and the ability to form internal spaces to meet people's needs for production, living, learning, and public activities. Because construction engineering requires testing the tensile strength of construction materials such as boards and steel bars.

[0003] A search revealed that Chinese Patent Publication No. CN216594480U discloses a tensile testing device for building engineering testing, comprising a bracket and a control console. The bracket is mounted on the upper end of the control console, and a transverse support plate is provided on the inner side of the bracket. Clamps are installed on both the support plate and the lower end face of the bracket. A tensioning mechanism for tensioning is provided between the support plate and the bracket. A longitudinal guide rod is provided on the outer side of the bracket, and an adjusting block for adjusting the tension limit is sleeved on the outer side of the guide rod. Multiple sets of buffer columns, made of rubber, are fixedly connected to the upper end face of the support plate. The device uses the cooperation of fixing bolts and fixing holes to fix the adjusting block on the guide rod according to usage requirements, thereby limiting the tension range. During the movement of the support plate, the connecting rod contacts the adjusting block, triggering a trigger button to control the threaded rod to rotate in the opposite direction, causing the support plate to spring back and stop the tensioning.

[0004] However, in the existing technology, when testing the tensile strength of steel bars, the steel bars are usually fixed on both sides to a clamp, and then the steel bars are stretched by moving the clamp to test the tensile strength of the steel bars. However, the existing devices do not have protective devices around the stretching components. When the steel bars are stretched to their limit, they will break. At this time, the fragments generated by the breakage will fly around the device. If the testing personnel are standing around the device at this time, it will cause great harm to the safety of the testing personnel. A solution is proposed to solve the problems mentioned in the background technology. Utility Model Content

[0031] 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.

[0032] Reference Figures 1 to 2 As shown, one embodiment of this utility model includes an operating table 1, a protective cover 6 slidably connected to one side of the operating table 1, a tempered glass 7 fixedly connected to one side of the protective cover 6, a No. 1 motor 3 fixedly connected to one side of the upper end of the operating table 1, a drive screw 4 rotatably connected to the upper end of the operating table 1, one end of the drive screw 4 fixedly connected to the output end of the No. 1 motor 3, one side of the upper end of the protective cover 6 threadedly connected to the outer surface of the drive screw 4, a hydraulic cylinder 5 fixedly connected to the upper end of the operating table 1, a sliding frame 9 fixedly connected inside the operating table 1, a pulling block 8 slidably connected to the outer surface of the sliding frame 9, and the output end of the hydraulic cylinder 5 fixedly connected to the upper end of the pulling block 8.

[0033] In this embodiment, when the device performs tensile testing, after fixing both ends of the reinforcing bar, the first motor 3 is started. The first motor 3 drives the drive screw 4 to rotate, which in turn moves the protective cover 6 to the side of the operating table 1. The protective cover 6 can protect the area around the operating table 1. At this time, the hydraulic cylinder 5 can be started to perform tensile testing on the reinforcing bar. During the inspection, the inside of the device can be observed through the tempered glass 7 on the side of the protective cover 6. In this way, when the device is performing tensile testing, the outside of the device can be blocked and protected by the protective cover 6. When the reinforcing bar inside the device breaks, the flying debris can be completely blocked by the protective cover 6, effectively preventing the flying debris from hitting the testing personnel, making the device safer to use.

[0034] Example 2, as Figures 1 to 5 As shown, a positioning block 10 is fixedly connected to the lower part of the operating table 1. A double-acting lead screw 17 is rotatably connected to both the interior of the pull block 8 and the interior of the positioning block 10. Clamping blocks 16 are slidably connected to both sides of one side of the pull block 8 and both sides of one side of the positioning block 10. One end of each clamping block 16 is threadedly connected to the outer surface of two double-acting lead screws 17. A mounting bracket 13 is fixedly connected to one side of the pull block 8. The movement and rotation of the mounting bracket 13 are connected to a first bevel gear 14. One end of each of the two double-acting lead screws 17 is fixedly connected to a second bevel gear 15. The outer surface of one of the second bevel gears 15 is connected to the outer surface of the first bevel gear 14. The surfaces are meshed. A fixed frame 19 is fixedly connected to the lower side of one side of the operating table 1. A third bevel gear 18 is rotatably connected to one side of the fixed frame 19. The outer surface of the third bevel gear 18 meshes with the outer surface of another second bevel gear 15. A hexagonal prism 2 is fixedly connected to the upper end of the third bevel gear 18. A second motor 11 is fixedly connected to the upper side of one side of the operating table 1. The output end of the second motor 11 is fixedly connected to the upper end of the hexagonal prism 2. The middle part of the first bevel gear 14 is slidably connected to the outer surface of the hexagonal prism 2. A sliding groove 12 is opened on one side of the operating table 1. The outer surface of the mounting frame 13 is slidably connected to the inside of the sliding groove 12.

[0035] In this embodiment, when clamping and fixing the ends of the reinforcing bars, the two ends of the reinforcing bars can be placed between the clamping blocks 16. Then, the second motor 11 can be started to drive the hexagonal prism 2 to rotate. The rotating hexagonal prism 2 can drive the first bevel gear 14 and the third bevel gear 18 to rotate, which in turn drives the second bevel gear 15, which is meshed with it, to rotate. At this time, the bidirectional lead screw 17, which is fixedly connected to the second bevel gear 15, can rotate accordingly, thereby driving the clamping blocks 16, which are threaded to it, to converge and clamp and fix the ends of the reinforcing bars. With this method, when clamping the ends of the reinforcing bars, only the drive of the second motor 11 is needed to clamp both sides of the reinforcing bars at the same time. Compared with the traditional device that requires clamping separately, this device is more convenient and faster to use, and effectively improves the detection efficiency of the device.

[0036] Working Principle: When the device performs tensile testing, after fixing both ends of the reinforcing bar, starting motor 3 drives the drive screw 4 to rotate, which in turn moves the protective cover 6 to the side of the operating platform 1. The protective cover 6 protects the area around the operating platform 1. At this time, the hydraulic cylinder 5 can be activated to perform the tensile testing of the reinforcing bar. During inspection, the interior of the device can be observed through the tempered glass 7 on the side of the protective cover 6. This method allows the device to be protected from external impact by the protective cover 6 during tensile testing. If the reinforcing bar breaks inside the device, the flying debris can be completely blocked by the protective cover 6, effectively preventing flying debris from hitting the testing personnel, making the device safer to use. The device also clamps the ends of the reinforcing bar. When holding the steel bar in place, both ends of the steel bar can be placed between the clamping blocks 16. Then, the second motor 11 can be started to drive the hexagonal prism 2 to rotate. The rotating hexagonal prism 2 can drive the first bevel gear 14 and the third bevel gear 18 to rotate, which in turn drives the second bevel gear 15, which is meshed with the first bevel gear 14, to rotate. At this time, the bidirectional lead screw 17, which is fixedly connected to the second bevel gear 15, can rotate accordingly, thereby driving the clamping blocks 16, which are threaded to the second bevel gear 15, to converge and clamp the ends of the steel bar. In this way, when clamping the ends of the steel bar, only the second motor 11 needs to be started to clamp both sides of the steel bar at the same time. Compared with the traditional device that requires clamping separately, this device is more convenient and faster to use, and effectively improves the detection efficiency of the device.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
