[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a rebar straightening device for geotechnical engineering.

[0034] Reference Figure 1 A rebar straightening device for geotechnical engineering includes a straightening platform 1, a support frame 2 installed on the top of the straightening platform 1, a fixed wheel set 3 and a movable wheel set 4 installed inside the support frame 2, the movable wheel set 4 and the fixed wheel set 3 are arranged vertically opposite to each other to form a straightening channel, and the fixed wheel set 3 is located below and is driven to rotate by a first drive unit 5; the movable wheel set 4 is located above and is driven to lift and adjust by a second drive unit 6.

[0035] Before the straightening process, the movable wheel set 4 is first adjusted up and down according to the size of the rebar to be straightened, using the second drive unit 6 to adjust the size of the straightening channel accordingly. During the straightening process, the rebar is input along the straightening channel formed between the movable wheel set 4 and the fixed wheel set 3, and guided by the first drive unit 5, so that the rebar is straightened by the fixed wheel set 3 and the movable wheel set 4. In this process, the movable wheel set 4 and the fixed wheel set 3 can ensure the rolling clamping and guiding of the rebar, making it less likely for the rebar to run away, thereby ensuring the straightening effect.

[0036] In this embodiment, the rollers in both the fixed wheel set 3 and the movable wheel set 4 have arc-shaped notches formed in the middle. During the straightening process, the rollers in the fixed wheel set 3 and the movable wheel set 4 can use the arc-shaped notches to clamp and limit the steel bars, making them less prone to slippage and better ensuring the stability of the straightening process.

[0037] Reference Figure 2Specifically, in this embodiment, the first drive unit 5 includes a first motor 51; wherein, the two sides of the fixed wheel set 3 are respectively rotatably inserted into the two sides of the support frame 2, and the rotating shaft of the right side of the fixed wheel set 3 extends outside the support frame 2. Adjacent rollers in the fixed wheel set 3 are linked by a sprocket 52 and a chain 53. The first motor 51 is fixedly installed on the top of the straightening table 1 and connected to the rotating shaft of the first roller via a reducer. During operation, the first motor 51 drives the first roller in the movable wheel set 4 to rotate, and under the transmission of the sprocket 52 and chain 53, synchronously drives all rollers in the movable wheel set 4 to rotate synchronously.

[0038] Reference Figure 1 and Figure 2 Specifically, in this embodiment, the two sides of the movable wheel assembly 4 are rotatably connected to two side plates 41. The support frame 2 has vertically extending grooves 21 on both sides, with sliders 22 slidably installed within the grooves 21. The side plates 41 on both sides are fixedly connected to the sliders 22 on both sides, allowing the movable wheel assembly 4 to be vertically slidably installed on the support frame 2.

[0039] Reference Figure 1 and Figure 2 The second drive unit 6 includes a second motor 61. A ball screw assembly 62 is mounted on the side of the support frame 2. The screw in the ball screw assembly 62 is vertically rotatable. The nut in the ball screw assembly 62 is fixedly connected to the slider 22 in the side plate 41 on the same side. The second motor 61 is fixedly mounted on the support frame 2 and faces downward. The second motor 61 is connected to the top of the screw in the ball screw assembly 62 through a reducer, so that the second motor 61 drives the movable wheel assembly 4 to adjust up and down through the ball screw assembly 62.

[0040] Due to the influence of the geotechnical engineering construction environment, the surface of the reinforcing bars is prone to adhering with some soil. In the actual straightening process, some soil can easily adhere to the surface of the movable wheel set 4 and the fixed wheel set 3, which can affect subsequent straightening treatment.

[0041] Reference Figure 1 In this embodiment, a first brush 7 is installed below the fixed wheel assembly 3, and a second brush 8 is installed above the movable wheel assembly 4. The first brush 7 and the second brush 8 are arranged vertically opposite each other, and the bristles of the first brush 7 and the second brush 8 extend to the wheel surfaces of the fixed wheel assembly 3 and the movable wheel assembly 4, respectively. As the rebar is guided, the bristles of the first brush 7 and the second brush 8 can clean the surfaces of the fixed wheel assembly 3 and the movable wheel assembly 4, respectively.

[0042] Reference Figure 3Specifically, in this embodiment, the correction table 1 has a first mounting port 71 below the fixed wheel assembly 3, and the first mounting port 71 is through-hole; the first brush 7 is pluggable and detachable and installed in the first mounting port 71, and both sides of the first brush 7 are formed with support flanges 9, which support the outer periphery of the first mounting port 71 and are fixedly connected to the bottom of the correction table 1 by screws 72, so as to realize the detachable installation of the first brush 7.

[0043] Reference Figure 4 Specifically, in this embodiment, the top of the support frame 2 has a second mounting opening 81, which is through-hole shaped. The second brush 8 is pluggably installed in the second mounting opening 81. Both sides of the second brush 8 are formed with support flanges 9, which support the outer periphery of the second mounting opening 81. The second brush 8 is detachably installed from the support frame 2, and the second brush 8 can be adjusted up and down.

[0044] Specifically, both sides of the support flange 9 are threaded to the top of the support frame 2 via adjusting bolts 82. Guide grooves 83, which are stepped grooves, are provided on both sides of the length of the second mounting opening 81 on the top of the support frame 2, extending through the top of the support frame 2. Correspondingly, guide rods 84 are provided at the bottom of the support flanges 9 on both sides of the second brush 8, and the guide rods 84 are slidably inserted into small holes in the guide grooves 83. Pre-tension springs 85 are fitted onto the guide rods 84, and the bottom of the pre-tension springs 85 is supported on the stepped surface in the guide grooves 83.

[0045] In actual use, the second brush 8 can be adjusted up and down according to the position of the movable wheel assembly 4. During the adjustment process, the second brush 8 is adjusted up and down by tightening or loosening the adjusting bolt 82 under the action of the preload spring 85.

[0046] The implementation principle is as follows: Before the straightening process, the movable wheel set 4 is adjusted up and down according to the size of the rebar to be straightened, based on the size of the rebar to be straightened, so as to adjust the size of the straightening channel accordingly. During the straightening process, the rebar is input along the straightening channel formed between the movable wheel set 4 and the fixed wheel set 3, and guided by the first drive unit 5, so that the rebar is straightened by the fixed wheel set 3 and the movable wheel set 4. In this process, the movable wheel set 4 and the fixed wheel set 3 can ensure the rolling clamping and guiding of the rebar, making it difficult for the rebar to run away, thereby ensuring the straightening effect.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
