[0025] 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.

[0026] Please see Figure 1-5 This utility model provides a technical solution:

[0027] A strength testing device for building steel, comprising:

[0028] Workbench 1, and a moving mechanism installed inside the workbench 1. The moving mechanism is equipped with a moving frame 7, and a first support block 8 and a second support block 9 are symmetrically fixedly installed on the top of the moving frame 7.

[0029] An adjustment mechanism is set on the top of the first support block 8 and the second support block 9. An installation plate 13 is slidably installed on the adjustment mechanism. A first cylinder 14 is fixedly installed on the top of the installation plate 13. A fixed frame 15 for steel hoisting is fixedly installed on the telescopic end of the first cylinder 14. A second positioning groove 17 for steel positioning is opened in the fixed frame 15.

[0030] The moving mechanism includes a drive motor 4, a lead screw 5 and a positioning rod 18. The drive motor 4 is fixedly installed on the side of the worktable 1. The lead screw 5 is fixedly installed on the output shaft of the drive motor 4 through a coupling. The lead screw 5 is rotatably installed inside the worktable 1. The moving frame 7 is threaded onto the lead screw 5.

[0031] The positioning rod 18 is fixedly connected inside the workbench 1, and the movable frame 7 is slidably mounted on the positioning rod 18;

[0032] The adjustment mechanism includes a second cylinder 22 and a positioning frame 11. An mounting block 12 is fixedly installed on the top of the first support block 8 and the second support block 9. The second cylinder 22 is fixedly installed on the side of the mounting block 12. The mounting plate 13 is slidably installed on the positioning frame 11. The telescopic end of the second cylinder 22 is fixedly installed on the mounting plate 13.

[0033] In this embodiment, when the steel is placed in the fixed frame 15, the second cylinder 22 pushes the mounting block 12, so that the mounting block 12 can drive the first cylinder 14 and the fixed frame 15 to move, thereby adjusting the position of the fixed frame 15 so that the workers can place the steel in the fixed frame 15.

[0034] A guide rod 16 is fixedly connected to the top of the fixed frame 15, and the guide rod 16 is movably inserted into the mounting plate 13;

[0035] Furthermore, when the steel is lifted by the retraction of the telescopic rod of the first cylinder 14, the positioning and limiting of the fixed frame 15 can be achieved by the guide rod 16, so that the fixed frame 15 can move smoothly.

[0036] The inner wall of the workbench 1 is fixedly connected to a support plate 2. Two sets of placement racks 3 for supporting steel are symmetrically arranged on the top of the support plate 2. The placement rack 3 is provided with a first positioning groove 6 for positioning steel.

[0037] It is worth mentioning that when the steel is placed in the first positioning groove 6 of the placement rack 3, the steel can be positioned by the first positioning groove 6.

[0038] Two sets of clearance channels 10 are symmetrically arranged on the support plate 2, with the first support block 8 and the second support block 9 respectively set in the two sets of clearance channels 10;

[0039] The side of the workbench 1 is provided with a clearance hole 21 corresponding to the second cylinder 22;

[0040] It is worth noting that when the moving mechanism moves the adjusting mechanism into the worktable 1, the second cylinder 22 moves into the clearance hole 21, thereby preventing it from affecting the handling of the steel.

[0041] In actual use, the worker first places the steel in the second positioning groove 17. The second positioning groove 17 can position the steel to prevent it from shaking when moving. After the steel is placed in the second positioning groove 17, the telescopic rod of the first cylinder 14 retracts to drive the fixed frame 15 back to its original position. Thus, the steel can be lifted when the fixed frame 15 moves. The drive motor 4 works, and the output shaft of the drive motor 4 rotates to drive the lead screw 5 to rotate. When the lead screw 5 rotates, it moves the moving frame 7 under the positioning of the positioning rod 18, so that the steel can be placed inside the worktable 1.

[0042] The first cylinder 14 pushes the fixed frame 15 through its telescopic end, allowing the steel to approach the placement frame 3 and be placed in the first positioning groove 6 on the placement frame 3. The placement frame 3 supports the steel. After the steel is placed in the placement frame 3, the first cylinder 14 continues to push the fixed frame 15 until the bottom of the fixed frame 15 contacts the top of the support plate 2. The fixed frame 15 can then detach from the steel. The drive motor 4 operates, and the output shaft of the drive motor 4 drives the lead screw 5 to rotate. The lead screw 5, in conjunction with the positioning rod 18, moves the moving frame 7, causing the fixed frame 15 to move out from under the steel. The hydraulic cylinder 19 operates, and its telescopic end pushes the detection head 20, causing the detection head 20 to perform a bending strength test on the steel.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
