Description

Technical Field

[0001] This utility model relates to the field of steel structure correction and installation technology, and more specifically, to a steel structure correction and installation frame. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are characterized by high strength, light weight, short construction period, and good seismic performance. They are widely used in urban housing construction projects and other fields. Steel structure straightening and installation frames are mainly used to ensure the accurate installation and stability of the entire steel structure. Since steel structures are easily squeezed during transportation, the surface may become uneven. If the flatness is not adjusted before use, it will cause inconvenience to subsequent adjustment work.

[0003] A search revealed Chinese patent application number CN202322235538.8, which discloses a steel structure straightening mounting frame, including a mounting plate, a horizontal component, and a straightening component. Two sets of mounting columns are fixedly connected to the top of the mounting plate and are arranged left and right. The horizontal component is located on the mounting columns and can be used to adjust the steel structure horizontally. The straightening component is located below the horizontal component and includes a mounting box, sliding rods, a cylinder, and a straightening plate. The straightening plate is slidably mounted on the mounting box. Two sets of sliding rods are fixedly connected to the front side of the straightening plate and are arranged left and right. A cylinder is fixedly connected to the front side of the mounting box, and the free end of the cylinder is fixedly connected to the straightening plate. When the cylinder is activated, it drives the straightening plate to move. The straightening plate can be used to straighten the steel structure.

[0004] Although the steel structure correction and installation frame described in the aforementioned patent can adjust the position of the steel structure through the coordinated use of the receiving plate, winch, rope, and pulley, and the two sets of winches make the horizontal adjustment of the steel structure more convenient during installation, making the steel structure more stable and easier to operate during construction, reducing adjustment and correction work, improving construction efficiency, and reducing construction time, the following shortcomings still exist in use: 1. The winch is set up separately and works with the rope to adjust the height of the receiving plate. The length of the rope is not easy to synchronize, which can easily cause the receiving plate to sway, posing a safety hazard; 2. When the device rises, if the receiving plate sways, the steel structure will be subjected to lateral impact force, pushing the sliding plate to shift instantaneously. Due to the lag in the dynamic response of the damper and spring, the sliding plate will respond slowly, resulting in an increase in the clamping gap, which can cause the steel structure to temporarily lose clamping force.

[0005] Therefore, there is an urgent need for a steel structure correction and mounting frame to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a steel structure correction mounting bracket to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A steel structure straightening mounting frame includes a mounting box, wherein symmetrically distributed mounting columns are fixedly connected to the top wall of the mounting box, and a receiving plate is slidably connected to the outer wall of the mounting columns. Symmetrically distributed winch boxes are fixedly connected to the top wall of the mounting box, and rotating rollers are rotatably connected to the inner wall of the winch boxes. The frame also includes:

[0009] A synchronous winding assembly includes a drive sprocket fixedly connected to the outer wall of a rotating roller. An adjusting sprocket is connected to the outer wall of the drive sprocket via a chain drive. A lifting column is rotatably connected to the outer wall of the adjusting sprocket. A fixing block is slidably connected to the outer wall of the lifting column and is fixedly connected to a mounting box. An adjusting screw is rotatably connected to the outer wall of the fixing block and is threadedly connected to the lifting column. A knob is fixedly connected to the outer wall of the adjusting screw.

[0010] Anti-sway components are installed on the outer wall of the support plate.

[0011] As a preferred technical solution of this application, the anti-sway component includes an L-shaped plate symmetrically fixedly connected to the outer wall of the receiving plate, a drive motor A fixedly connected to the outer wall of the L-shaped plate located on the rear side, a bidirectional screw fixedly connected to the output end of the drive motor A, and the bidirectional screw being rotatably connected to the L-shaped plate, a positioning block being threadedly connected to the outer wall of the bidirectional screw, and the positioning block being slidably connected to the receiving plate.

[0012] As a preferred technical solution of this application, the top wall of the receiving plate is fixedly connected with symmetrically distributed snap-fit ​​boxes, the outer wall of the snap-fit ​​boxes is fixedly connected with symmetrically distributed spring dampers, the outer wall of the spring dampers is fixedly connected with a sliding plate, and the sliding plate is slidably connected to the snap-fit ​​boxes.

[0013] As a preferred technical solution of this application, a pull rope is wound around the outer wall of the rotating roller, and the end of the pull rope away from the rotating roller is fixedly connected to the receiving plate.

[0014] As a preferred technical solution of this application, a drive motor B is fixedly connected to the outer wall of the winch box on the left side, and the output end of the drive motor B is fixedly connected to the rotating roller.

[0015] As a preferred technical solution of this application, a cylinder is fixedly connected to the outer wall of the mounting box, a calibration plate is fixedly connected to the output end of the cylinder, and the calibration plate is slidably connected to the mounting box. Symmetrically distributed sliding rods are fixedly connected to the outer wall of the calibration plate, and the sliding rods are slidably connected to the mounting box.

[0016] As a preferred technical solution of this application, the top wall of the mounting column is fixedly connected to a fixed seat, the outer wall of the fixed seat is rotatably connected to a pulley, and the pulley is connected to a pull rope drive.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] 1. By using the drive sprocket, chain, and adjusting sprocket, the rotation speed of the rotating roller is synchronously adjusted, making the lifting and lowering of the receiving plate more stable. This avoids the tilting or swaying of the steel structure caused by asynchronous lifting and lowering, improving the accuracy and safety of the installation. At the same time, through the cooperation of the adjusting screw, adjusting sprocket, and chain in the synchronous winding assembly, the length of the pull rope can be easily adjusted to ensure that the lengths of the two sets of pull ropes are consistent, keeping the steel structure horizontal during the lifting process. This improves the accuracy and stability of the installation and solves the problem in the existing technology where the winch is set up separately and works with the pull rope to adjust the height of the receiving plate. The length of the pull rope is not easy to synchronize, which can easily lead to the swaying of the receiving plate and pose a safety hazard.

[0020] 2. The anti-sway assembly, including drive motor A, bidirectional screw, and positioning block, can position the steel structure from the side when the supporting plate shakes during the ascent of the receiving plate, causing a temporary clamping failure of the sliding plate. This effectively prevents the steel structure from shaking during lifting and installation, improving the safety and reliability of the installation. It solves the problem in the prior art where, when the receiving plate shakes during the ascent of the device, the steel structure is subjected to lateral impact force, causing the sliding plate to shift instantaneously. Due to the lag in the dynamic response of the damper and spring, the sliding plate responds slowly, leading to an increase in the clamping gap and a temporary loss of clamping force on the steel structure.
