Description

Technical Field

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

[0002] When dismantling and recycling existing steel structure buildings, some steel structures will bend due to long-term use. During dismantling, some steel structures will also bend. At the same time, some steel structures will bend during transportation and loading and unloading. Some slightly bent steel structures still have a certain secondary use value after simple straightening, and can be used for connecting non-load-bearing structures or for guardrails, etc.

[0003] The Chinese utility model patent application number CN202022316530.0 in the prior art relates to a straightening device for steel structure production, including a workbench, a mounting plate, a motor, a driving wheel, a belt, a sliding plate, a driven wheel, an electric telescopic rod, a fixed plate, a slide, a support seat, a shock-absorbing pad and bolts, etc., which can repeatedly straighten steel to achieve better processing results.

[0004] In actual use, the above device uses a pressure roller to repeatedly roll the surface of the steel structure. However, during the actual straightening process, the two ends of the steel structure do not have the ability to be fixed, which causes a certain curvature of the steel structure as a whole, affecting subsequent secondary use. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a steel structure straightening device that limits and adjusts the position of the steel structure through a limiting device, extrudes and corrects the bent and deformed part of the steel structure through a pressing device, and assists in pressing the main body of the steel structure through a straightening device, thereby reducing the warping of the two ends of the bent area during the process of squeezing the bent area of ​​the steel structure by the pressing device, thereby improving the practicality of the device.

[0006] The utility model discloses a steel structure straightening device, which comprises a limiting device, a pressing device and a straightening device. The pressing device is installed on the limiting device, and the straightening device is installed on the pressing device. The position of the steel structure is limited and adjusted by the limiting device, the bent and deformed part of the steel structure is squeezed and corrected by the pressing device, and the main body of the steel structure is auxiliary pressed by the straightening device, thereby reducing the situation where the two ends of the bent area of ​​the steel structure are warped during the process of the pressing device squeezing the bent area of ​​the steel structure, thereby improving the practicality of the device.

The rotating bidirectional lead screws drive the two groups of transverse moving platforms to move toward each other and cooperate with the two groups of pushing plates to push the steel plates on the frame, thereby pushing the steel structure to the middle of the frame for positioning, providing support for the front and rear parts of the steel structure through the support plate, and increasing the structural strength of the support plate through the reinforcing ribs to improve the practicability of the device.

A group of limiting light rods are respectively provided on the left and right sides of the upper end surface of the straightening and pressing plate frame, and the upper parts of the two groups of limiting light rods pass through the upper end surface of the gantry and extend to the upper side of the gantry; after the limiting device completes the adjustment of the position of the steel structure, the first hydraulic cylinder is controlled to extend to move the straightening and pressing plate frame downward, so that the straightening and pressing plate frame squeezes the bent part of the steel structure and flattens the bent area. The lifting and lowering process of the straightening and pressing plate frame is limited by the two groups of limiting light rods, thereby reducing the influence of the lateral force on the first hydraulic cylinder during the extrusion of the steel structure, thereby improving the stability and practicality of the device.

[0010] Preferably, the straightening device includes a first rotating shaft seat, a second hydraulic cylinder, a second rotating shaft seat, a shaft sleeve connecting piece and an auxiliary pressure plate frame.

The auxiliary pressure plate frame is driven to rotate downward by controlling the extension of the second hydraulic cylinder, thereby auxiliary squeezing of the front and rear of the steel structure is performed, reducing the warping curvature of the two ends of the steel structure when the pressing device is operating, improving the straightening effect of the device, and improving the practicality of the device.
