Description

Technical Field

[0001] This invention relates to the field of steel structure column and beam straightening technology, specifically a steel structure straightening device. Background Technology

[0002] Steel structures are building structures primarily made of steel. Steel is characterized by high strength, light weight, good overall rigidity, and strong deformation capacity, making it particularly suitable for constructing large-span, super-high, and super-heavy buildings. Its good homogeneity and isotropy allow it to withstand dynamic loads well, making steel frame structures a common structural form in modern construction engineering. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. Due to its light weight and simple construction, it is widely used in large factories, stadiums, and super high-rise buildings. Steel structure columns and beams require straightening equipment during use. However, existing steel structure column and beam straightening equipment requires rotating and flipping the steel structure columns and beams before straightening to achieve comprehensive straightening quality, making the process cumbersome and hindering the rapid and comprehensive straightening of steel structure columns and beams, thus affecting the efficiency of steel structure column and beam straightening. Therefore, we propose a steel structure straightening device. Summary of the Invention

[0003] The purpose of this invention is to provide a steel structure straightening device to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A steel structure straightening device includes a base and a straightening platform fixedly installed on the upper end of the base. A carrier assembly is provided on the base, and a steel structure column beam is placed on the carrier assembly. A limit assembly is provided on the inner side of the straightening platform to clamp and limit the steel structure column beam. A straightening frame is provided inside the straightening platform. A lower straightening assembly is provided at the bottom end of the straightening frame to straighten the top surface of the steel structure column beam. An upper straightening assembly is provided at the upper end of the straightening frame to straighten the bottom surface of the steel structure column beam. A driving assembly is provided on the base to drive the straightening frame to move along the steel structure column beam.

[0006] Preferably, the carrier assembly includes a first electric push rod and a carrier frame fixedly installed on the telescopic end of the first electric push rod. The first electric push rod is fixedly installed on the inner bottom end of the base, and the surface of the straightening table has an opening.

[0007] Preferably, a guide frame is fixedly installed on the surface of the base, and a guide slider is fixedly installed at the bottom end of the opening, with the guide slider slidably connected to the guide frame.

[0008] Preferably, the limiting component includes a second electric push rod and a front limiting block fixedly installed on the telescopic end of the second electric push rod. The second electric push rod is fixedly installed on the inner front end of the straightening platform. An assembly seat is fixedly installed on the inner rear end of the straightening platform. A sliding groove is provided on the side of the assembly seat. A slide block is fixedly connected to the sliding groove. A spring is fixedly connected between the slide block and the assembly seat. A rear limiting block is fixedly installed at one end of the slide block.

[0009] Preferably, anti-slip blocks are fixedly installed on the end faces of both the front limit block and the rear limit block, and the anti-slip blocks are components made of rubber.

[0010] Preferably, the lower straightening assembly includes a base frame and a straightening wheel rotatably mounted on the upper end of the base frame. The base frame is fixedly mounted on the inner bottom end of the straightening frame, and a straightening groove is formed on the surface of the straightening wheel.

[0011] Preferably, the upper straightening assembly includes a top frame and a straightening pressure roller rotatably mounted on the bottom end of the top frame. The surface of the straightening pressure roller is provided with a straightening top groove. A hydraulic cylinder is fixedly mounted on the top of the straightening frame, and the top frame is fixedly mounted on the telescopic end of the hydraulic cylinder.

[0012] Preferably, a limiting block is fixedly installed on the side of the top frame, a limiting rod is fixedly installed inside the straightening frame, and the limiting block is movably sleeved on the outside of the limiting rod.

[0013] Preferably, the drive assembly includes a motor and a lead screw shaft fixedly connected to the motor drive shaft. The motor is fixedly installed on the top side of the rear end of the straightening table. A transmission block is fixedly installed on the side of the straightening frame. The transmission block is threadedly connected to the lead screw shaft. A guide rail is fixedly installed on the straightening table. A limit roller is rotatably installed at the bottom of the straightening frame. The limit roller is in rolling connection with the guide rail.

[0014] Preferably, a bearing seat is fixedly installed on the top front side of the straightening table via a connecting frame, and the bearing seat is rotatably connected to one end of the lead screw shaft.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention clamps and limits the steel structure column and beam between the front and rear limiting blocks. A hydraulic cylinder drives the top frame to descend, causing the straightening pressure roller to press against the steel structure column and beam. This brings the top surface of the steel structure column and beam into contact with the straightening groove of the straightening pressure roller. A motor drives the straightening frame to move along the steel structure column and beam. The straightening pressure roller and straightening support roller can be used to straighten the top and bottom surfaces of the steel structure column and beam, respectively. This eliminates the need to rotate and flip the steel structure column and beam before straightening, simplifying the straightening process and facilitating quick and comprehensive straightening of the steel structure column and beam, thus improving the efficiency of steel structure column and beam straightening.

[0037] When using this device, the steel structure column beam 8 is placed on the support frame 22, with the bottom surface of the steel structure column beam 8 contacting the straightening groove 53 of the straightening roller 52. The second electric push rod 31 drives the front limit block 32 to move towards the front end of the steel structure column beam 8 until the steel structure column beam 8 is clamped and limited between the front limit block 32 and the rear limit block 37. The hydraulic cylinder 41 drives the top frame 61 to descend, causing the straightening pressure roller 62 to press against the steel structure column beam 8, so that the top surface of the steel structure column beam 8 contacts the straightening groove 53 of the straightening pressure roller 62. The straight top groove 63 uses the first electric push rod 21 to drive the support frame 22 to descend and move to the bottom side of the opening 13. The motor 71 drives the lead screw shaft 72 to rotate, which can drive the straightening frame 4 to move along the steel structure column beam 8. The straightening pressure roller 62 and the straightening load roller 52 can respectively straighten the top and bottom surfaces of the steel structure column beam 8. When the steel structure column beam 8 is deformed by straightening, the spring 35 can make the rear limit block 37 slide along the slide groove 34 to achieve rapid and comprehensive straightening of the steel structure column beam 8.
