Description

Technical Field

[0001] The utility model relates to the field of steel structure straightening, in particular to a steel structure straightening device. Background Art

[0002] Steel structures are made of steel and are one of the main types of building structures. They primarily consist of components such as beams, columns, and trusses, made from sections of steel and steel plates. During construction, straightening devices are often required to straighten twisted and bent steel columns. Steel straightening devices are specialized equipment used to process steel structures (such as columns and beams) to eliminate irregular deformations incurred during production, transportation, or installation, ensuring they meet specified length, diameter, and shape requirements.

[0003] A common steel structure straightening device includes a base, side support beams, anti-slip clamping rollers, a motor and a reducer. The steel structure straightening device has multiple sets of horizontal mechanical rollers and vertical mechanical rollers staggered on the outer wall of the side support beam. The mechanical rollers are used to squeeze and correct the steel structure entering the device, and external force is applied to cause the steel structure to deform within the elastic or plastic range. The bent part is gradually eliminated by rolling, thereby achieving the purpose of straightening.

[0004] Since the steel structures that need to be straightened at the construction site are often attached with large particles of impurities, the rollers in the steel structure straightening device will cause wear of the rollers when squeezing the steel structure, and the rollers need to be replaced. The common steel structure straightening device first needs to turn multiple fixing screws to release the vertical limit of the bearing seat that fixes the rollers, and then turn the fixing screws on the bearing seat to complete the disassembly of the rollers. After replacement, multiple screws also need to be turned for installation. The process is cumbersome and inconvenient, and the efficiency is low. Therefore, the existing steel structure straightening device needs to be modified. Utility Model Content

[0011] By adopting the above technical solution, it is beneficial to drive the transmission plate to move through the meshing of the teeth, and it is beneficial to limit the fixed cover plate so that it will not loosen during use.

[0012] Furthermore, the transmission component includes a transmission plate, a first transmission tooth, a second transmission tooth, a transmission gear, an extrusion plate and a third transmission tooth. Multiple groups of first transmission teeth and multiple groups of second transmission teeth are installed at equal distances on the outer wall of the transmission plate, and multiple groups of third transmission teeth are installed at equal distances on the outer wall of the extrusion plate. The transmission gear is rotatably installed on the inner wall of the sliding seat, and the width of the transmission gear is greater than the sum of the widths of the transmission plate and the extrusion plate.

[0014] Furthermore, the transmission gear meshes with the second transmission tooth and the third transmission tooth, and the first transmission tooth meshes with the fixed tooth.

[0016] Furthermore, the extrusion block is designed with a circular arc bulge, and the side of the fixed seat close to the fixed seat is designed with a circular arc bulge symmetrical to the extrusion block.

[0017] By adopting the above technical solution, it is beneficial to extrude and fix the bearing seat.

[0018] Furthermore, multiple groups of limit grooves are symmetrically arranged on the outer wall of the bearing seat, and the limit grooves are designed as circular arc grooves corresponding to the extrusion blocks.

[0019] By adopting the above technical solution, the left and right positions of the bearing seat can be limited after the bearing seat enters the device body.

[0020] Furthermore, when the extrusion block is in an unclamped state, the distance between the extrusion block and the fixing seat is greater than the width of the bearing seat.

[0035] Please refer to Figure 1 - Figure 6 , the cross-section of the sliding seat 12 is in a "C" shape, and the height of the sliding seat 12 is greater than the height of the fixed seat 11, which is beneficial to the movement of the transmission component in the sliding seat 12 and makes the fixed cover plate 3 keep horizontal with the sliding seat 12 after rotating to a horizontal state.

[0036] Please refer to Figure 1 - Figure 6The fixed cover plate 3 is installed with multiple sets of fixed teeth 31 at equal angles at the end near the sliding seat 12, and the limiting seat 6 is symmetrically installed with multiple sets on the outer wall of the fixed seat 11, and the width of the limiting cover plate 61 corresponds to the width of the fixed cover plate 3, which is conducive to driving the transmission plate 4 to move through the engagement of the teeth, and is conducive to limiting the fixed cover plate 3, and will not loosen during use.

[0037] See also Figure 1 - Figure 6 The transmission assembly includes a transmission plate 4, a first transmission tooth 41, a second transmission tooth 42, a transmission gear 43, an extrusion plate 44 and a third transmission tooth 45. Multiple groups of first transmission teeth 41 and multiple groups of second transmission teeth 42 are equidistantly installed on the outer wall of the transmission plate 4, and multiple groups of third transmission teeth 45 are equidistantly installed on the outer wall of the extrusion plate 44.
