Abstract
Description
Technical Field
[0001] This utility model relates to the field of rebar testing technology, and in particular to a rebar strength testing device. Background Technology
[0002] Steel bars refer to steel materials used in reinforced concrete and prestressed reinforced concrete structures. With their high strength and good mechanical properties such as plasticity and toughness, they play a role in bearing tensile and compressive forces, distributing loads, and improving the overall stability of the structure.
[0003] During the process of testing the bending degree of reinforcing bars, the operator needs to place the reinforcing bar samples to be tested one by one inside the equipment for bending degree testing. It is not possible to test different bending degrees of reinforcing bars of different diameters at the same time, which leads to a decrease in testing efficiency. Therefore, multiple sets of reinforcing bar clamping mechanisms can be installed to test the bending degree of different reinforcing bars at the same time, thereby improving testing efficiency. Thus, multi-layer reinforcing bar clamping components need to be installed to test the strength of multiple reinforcing bars of different diameters.
[0004] However, existing steel reinforcement strength testing devices have the following shortcomings:
[0005] (1) When using traditional steel bar bending test devices, it is necessary to manually place steel bar samples of different diameters into the test device one by one for testing. The testing efficiency is low, which not only increases the workload, but may also lead to inaccurate test results due to inconsistency of test conditions, thus affecting the accuracy and reliability of the test.
[0006] (2) The protective door of the traditional steel bar bending test device is opened or closed manually. If workers need to perform these operations before and after each test, it will increase the workload of workers and may also lead to a decrease in operating efficiency, thereby affecting the overall production efficiency. Utility Model Content

The steel bars are then bent by the bending column, and it is observed whether cracks appear on the outside of the steel bars. Therefore, a steel bar strength testing device is proposed.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0027] Example 1, as shown in the attached document Figure 1 - Appendix Figure 5 As shown, this utility model provides a technical solution: a steel bar strength testing device, including a main body 1, and a moving mechanism 2 fixedly connected to the top of the main body 1;
[0028] The main structure 1 includes a support frame 101. A first hole 102 is formed at the top of the support frame 101. A first bearing 103 is installed on the inner wall of the first hole 102. A rotating platform 104 is rotatably connected to the inner wall of the first bearing 103. A support plate 105 is fixedly connected to the top of the support frame 101. Three connecting frames 106 are fixedly connected to one side of the outer wall of the support plate 105. Clamping plates 107 are fixedly connected to one side of the outer wall of each of the three connecting frames 106. A set of mounting holes 108 is formed on one side of the outer wall of each of the three connecting frames 106. A set of electric push rods 109 is installed inside each of the three connecting frames 106. Clamping plates 110 are fixedly connected to the output ends of each of the three sets of electric push rods 109. The inner walls of the three clamping plates 110 are movably connected with steel reinforcement bodies 111. The top of the support frame 101 is fixedly connected with a protective frame 112. The inner wall of the protective frame 112 is provided with two cylinders 113. The output ends of the two cylinders 113 are fixedly connected with connecting blocks 114. The top of the connecting block 114 is provided with a second hole 115. The inner wall of the second hole 115 is provided with a second bearing 116. The inner wall of the second bearing 116 is rotatably connected with a rotating block 117. The bottom of the rotating block 117 is fixedly connected with a bending column 118, and the bottom of the bending column 118 is movably inserted into the inside of the rotating table (104). A controller 119 is fixedly connected to one side of the outer wall of the support frame 101.
[0029] The overall effect achieved by the device in Embodiment 1 is as follows: by setting up a multi-layer steel bar clamping assembly, the clamping assembly is moved and clamped by a driving device, which can clamp and fix steel bars of different sizes, so as to maintain stability during the bending test. Before the strength test, the operator needs to insert steel bars of different sizes into the clamping piece 107 and the clamping plate 110 outside the connecting frame 106 in sequence, and move the clamping plate 110 by the driving device, so as to clamp the steel bars, which is convenient for subsequent bending. It is convenient for steel bars of different sizes, but with unified testing standards and parameters, thereby ensuring the consistency and accuracy of the test results.
[0030] Example 2, as Figure 1-5As shown, the moving mechanism 2 includes two door frames 201. A rack plate 202 is fixedly connected to the top of each door frame 201. Gears 203 are meshed with the outer walls of each rack plate 202. Rotating rods 204 are movably inserted into the inner walls of each gear 203. A motor 205 is fixedly connected to one side of the outer wall of each rotating rod 204. A housing 206 is provided on the outer walls of each motor 205. An observation glass 207 is fixedly connected to the inner walls of each door frame 201. The inner wall of the protective frame 112 is slidably connected to the outer walls of the two door frames 201. The top of the protective frame 112 is fixedly connected to the outer walls of the two motors 205. The top of the protective frame 112 is fixedly connected to the bottom of the housing 206.
[0031] The effect achieved by the entire embodiment 2 is as follows: the automatic opening and closing of the moving door assembly can improve the efficiency of steel bar inspection and save manpower. When the staff is conducting the inspection, the drive assembly drives the other transmission components to rotate, thereby driving the protective door to move and open. The moving speed is fast, the efficiency is high, the stability is high when closing, and the protective performance is good.
[0032] Working principle: First, the bending degree of the reinforcing steel needs to be tested to check whether cracks or fractures occur after bending deformation, thereby determining the toughness and processing performance of the reinforcing steel. Before the equipment performs the test, the gear 203 outside the rotating rod 204 is driven by the motor 205 to rotate. The gear 203 meshes with the rack plate 202, thereby moving the door frame 201 installed at the bottom of the rack plate 202 to open the device. After opening, reinforcing steel samples of different diameters with the same testing standard and parameters are selected and placed one by one between the clamping piece 107 and the clamping plate 110 outside the connecting frame 106. Then, the electric push rod 109 installed inside the connecting frame 106 drives the clamping plate 110 to move. The holding plate 110 moves to clamp the steel bar sample. After the steel bar samples of different sizes are clamped, the cylinder 113 drives the bottom connecting block 114 to descend, and the rotating block 117 to descend until the bottom bending column 118 is inserted into the designated slot opened on the top of the rotating table 104. Finally, the main drive device at the bottom of the support frame 101 makes the rotating table 104 rotate, and at the same time drives the bending column 118 to rotate, and performs the bending operation according to the specified bending angle and bending diameter. The staff can then observe the inside through the observation glass 207. After bending, the steel bar sample is taken out to observe whether there are cracks or other defects in the bent part, and then the data is recorded and analyzed and resolved later.
