Description

Technical Field

[0001] The utility model relates to the technical field of steel sheet pile correction, and more specifically, the utility model relates to a cold bending correction device for steel sheet piles. Background Art

[0002] In construction projects, water conservancy projects and bridge construction, steel sheet piles, as an important building material, are widely used in fields such as cofferdams, foundation pit support, retaining walls, etc. However, during the production, transportation and installation of steel sheet piles, due to the influence of various factors (such as processing errors, transportation collisions, installation stresses, etc.), the steel sheet piles often have varying degrees of bending and deformation. These bending and deformations not only affect the service performance of the steel sheet piles, but also may pose a threat to the safety and stability of the overall project. Therefore, it is particularly important to correct the steel sheet piles in a timely and effective manner.

[0003] Traditional correction methods are difficult to maintain the stable position of the steel sheet piles during the correction process, and are prone to deviation, resulting in low correction accuracy and affecting the correction effect. Moreover, the thicknesses and specifications of the steel sheet piles used in different projects vary, and traditional correction methods often lack adaptability to steel sheet piles of different specifications, and the correction effect is limited. In response to the above problems, this device was invented. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a cold bending correction device for steel sheet piles to solve the problems raised in the above background art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions: A cold bending correction device for steel sheet piles includes a first frame and a second frame. A first bracket is fixedly installed at the top of the first frame. A first cylinder is fixedly installed at the middle position of the top of the first bracket. The end of the piston rod of the first cylinder is fixedly connected to a pressing block. Second brackets are fixedly installed at the tops on both sides of the first frame. A connecting frame is fixedly installed on the second brackets. A primary correction mechanism is arranged on the connecting frame. A secondary correction mechanism is arranged on the second frame.

[0006] Further, the primary correction mechanism includes a one-way screw rod rotatably installed on the connecting frame. A first motor is fixedly installed on the connecting frame, and the output shaft of the first motor is connected to the one-way screw rod.

An inverted U-shaped frame is fixedly installed at the bottom of the second cylinder. A first pressing roller is rotatably installed on the inverted U-shaped frame.

[0007] Further, the width inside the connecting frame is equal to the width of the first moving block.

[0008] Further, the pressing block is arranged between the two first pressing rollers on both sides.

[0009] Furthermore, installation grooves are formed on both sides of the second rack. The secondary straightening mechanism includes a bidirectional screw rod rotatably installed on both sides of the second rack. Second motors are fixedly installed at the tops of both sides of the second rack. Two second moving blocks are threadedly connected to both sides of the bidirectional screw rod. A second pressing roller is rotatably installed between the two second moving blocks on the same horizontal plane.

[0010] Furthermore, the width of the installation groove is equal to the width of the second moving block.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] The pressing block driven by the first air cylinder of the present utility model can firmly fix the steel sheet pile before straightening, ensuring the stable position of the steel sheet pile without deviation during the straightening process, thereby improving the accuracy and efficiency of straightening. The primary straightening mechanism and the secondary straightening mechanism are designed. The primary straightening mechanism drives a unidirectional screw rod through a first motor, drives a first moving block and a first pressing roller to move along the connecting frame, and realizes the preliminary straightening of the steel sheet pile.

[0022] Embodiment:

[0023] Referring to the attached Figures 1-4 , a cold bending and straightening device for steel sheet piles in this embodiment includes a first frame 1 and a second frame 2. The first frame 1 and the second frame 2 are fixedly connected. A plurality of conveying rollers are provided on both the first frame 1 and the second frame 2, realizing the stable conveyance of steel sheet piles. A first support 3 is fixedly installed at the top of the first frame 1. A first cylinder 4 is fixedly installed at the middle position of the top of the first support 3. The end of the piston rod of the first cylinder 4 is fixedly connected with a pressing block 5. When in use, the first cylinder 4 is turned on, and the piston rod of the first cylinder 4 drives the pressing block 5 to move downward to fix the steel sheet pile, ensuring that the position of the steel sheet pile is stable and does not shift during the straightening process, improving the straightening accuracy and efficiency.

[0024] Referring to the attached Figure 1 , Figure 3 and Figure 4, on both sides of the top of the first rack 1, second brackets 6 are fixedly installed. The two second brackets 6 are arranged in parallel, and the first bracket 3 and the second bracket 6 are arranged perpendicular to each other. A connecting frame 7 is fixedly installed on the second bracket 6. An initial straightening mechanism 8 is arranged on the connecting frame 7. The initial straightening mechanism 8 includes a one-way screw 801 rotatably installed on the connecting frame 7. A first motor 802 is fixedly installed on the connecting frame 7, and the output shaft of the first motor 802 is connected to the one-way screw 801. When in use, turning on the first motor 802 can realize the rotation of the one-way screw 801. A first moving block 803 is threadedly connected to the one-way screw 801. The width of the inside of the connecting frame 7 is equal to the width of the first moving block 803, thus realizing the limitation of the first moving block 803, enabling the first moving block 803 to move along the connecting frame 7 during the rotation of the one-way screw 801. A second cylinder 804 is fixedly installed at the bottom of the first moving block 803. A U-shaped frame 805 is fixedly installed at the bottom of the second cylinder 804. A first pressing roller 806 is rotatably installed on the U-shaped frame 805. The pressing block 5 is arranged between the two first pressing rollers 806 on both sides.

[0025] When in use, turn on the second cylinder 804 and the first motor 802. The piston rod of the second cylinder 804 drives the U-shaped frame 805 and the first pressing roller 806 to move until the first pressing roller 806 contacts the top of the steel sheet pile. The first motor 802 drives the one-way screw 801 to rotate, realizing the movement of the first moving block 803, the second cylinder 804, and the first pressing roller 806, and further realizing the preliminary straightening of the steel sheet pile.

[0026] Refer to the appendix Figure 1 and Figure 2 , a secondary straightening mechanism 9 is arranged on the second rack 2. Installation grooves 10 are opened on both sides of the second rack 2. The secondary straightening mechanism 9 includes a bidirectional screw 901 rotatably installed on both sides of the second rack 2. Second motors 904 are fixedly installed on the tops of both sides of the second rack 2, and the second motors 904 are connected to the bidirectional screw 901. When in use, turning on the second motors 904 can realize the rotation of the bidirectional screw 901. Second moving blocks 902 are threadedly connected to both sides of the bidirectional screw 901. The width of the installation groove 10 is equal to the width of the second moving block 902, thus realizing the limitation of the second moving block 902, enabling the two second moving blocks 902 threadedly connected to the same bidirectional screw 901 to move towards or away from each other during the rotation of the bidirectional screw 901. A second pressing roller 903 is rotatably installed between the two second moving blocks 902 on the same horizontal plane. The two second pressing rollers 903 can move towards or away from each other under the action of the second moving blocks 902. The steel sheet pile passes through between the two second pressing rollers 903, and the secondary straightening of steel sheet piles with different thicknesses can be carried out.

[0027] The cold bending correction device for steel sheet piles transmits the steel sheet piles through the transmission rollers on the first frame 1 and the second frame 2, fixes the steel sheet piles by the pressing block 5 driven by the first cylinder 4, and then drives the one-way screw rod 801 to rotate by the first motor 802 in the primary correction mechanism 8, drives the first moving block 803 to move along the connecting frame 7, and further adjusts the position of the first pressing roller 806 through the second cylinder 804 and the inverted U-shaped frame 805 to perform primary correction on the steel sheet piles. The second motor 904 in the secondary correction mechanism 9 drives the bidirectional screw rod 901 to rotate, so that the two second moving blocks 902 drive the second pressing rollers 903 to move towards each other to perform further precise correction on the steel sheet piles.

[0028] Finally, the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
