Description

Technical Field

[0001] This utility model mainly relates to the field of straightening technology for H-shaped steel structure beams, specifically a straightening device for H-shaped steel structure beams. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, steel structures are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. Steel structures are prone to corrosion, and generally require rust removal, galvanizing, or painting, as well as regular maintenance. H-beams are a type of steel structure; their simple structure and ease of use facilitate construction. During the production of H-beams, straightening is required.

[0003] The publication number is CN217251730U, which discloses a straightening device for the production of steel structure columns and beams. Specifically, it discloses: a limiting seat is provided above the fixed seat, and fixed plates are fixedly connected to both sides of the top of the limiting seat. A limiting screw is provided inside the fixed plate. The outer side wall of the limiting screw is provided with an external thread, and the inner side wall of the fixed plate is provided with an internal thread that matches the external thread. An adjusting handle is fixedly connected to one side of the limiting screw, and a limiting plate is fixedly connected to the other side of the limiting screw. Rotating the adjusting handle will drive the limiting screw to move horizontally, thereby changing the direction of the limiting plate. After the limiting plate is in contact with the side of the component, the adjusting handle is rotated again to clamp the component.

[0004] While the aforementioned patent can clamp the bent component, the bent component will extend to both ends to different degrees during the flattening process of the hydraulic cylinder. At this time, the bent component is still in a clamped state, which may cause damage to the clamping assembly and is not conducive to flattening the bent component. Therefore, we propose a straightening device for steel structure column and beam production to solve this problem. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a straightening device for H-shaped steel structure beams. This utility model, through a transmission component, can drive a moving platform to move left and right, thereby moving the structural steel beam left and right, and thus straightening the structural steel beam at different positions. Through the cooperation of strip rails, sliding blocks, and locking bolts, the position of the U-shaped support plate can be adjusted, thus meeting the clamping and limiting requirements for different types of structural steel beams, improving the applicability of this device. By incorporating a spring-loaded component, during straightening, the two ends of the structural steel beam can be pushed by the spring force of the spring-loaded component to move the U-shaped support plate, thereby preventing damage to the U-shaped support plate during the straightening extension of the structural steel beam, and ensuring the smooth progress of the straightening operation.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

[0007] A straightening device for H-shaped steel structure beams includes a workbench. A transmission assembly is mounted on the top surface of the workbench. A moving platform is mounted on the transmission assembly. Two strip-shaped slide rails, distributed front to back, are installed on the top surface of the moving platform. Two sliding blocks, distributed left to right, are slidably mounted on the two strip-shaped slide rails. A locking bolt is installed in front of each sliding block. A spring-loaded assembly is mounted on each sliding block. A U-shaped support plate is mounted on the spring-loaded assembly. Adjusting screws are threaded onto the front and rear of each U-shaped support plate. A clamping plate is rotatably mounted on each adjusting screw. The bottom surface of each clamping plate slides in contact with the U-shaped support plate. A straightening assembly is mounted on the top surface of the workbench.

[0008] Furthermore, the transmission assembly includes two left and right distributed fixed plates, which are fixedly connected to the worktable. A servo motor is installed on one side of one of the fixed plates, and a lead screw is installed at one end of the servo motor shaft. The lead screw is rotatably connected to the other fixed plate and passes through the moving platform and is threadedly connected to the moving platform.

[0009] Furthermore, a limit rod is slidably installed on the mobile platform, and the two ends of the limit rod are respectively fixedly connected to two fixed plates.

[0010] Furthermore, the rebound assembly includes:

[0011] The top surface of each sliding block has two strip-shaped grooves distributed front and back. A guide rod is installed in each strip-shaped groove, and a connecting block is slidably installed on each guide rod.

[0012] A strip block is installed between the top surfaces of the two connecting blocks located on the same sliding block. Each strip block is fixedly connected to the corresponding U-shaped support plate. A spring is fitted on the outer periphery of one end of each guide rod. One end of each spring is connected to the strip groove, and the other end of each spring is connected to the connecting block.

[0013] Furthermore, the straightening assembly includes a horizontal plate, with support rods installed at the four corners of the bottom surface of the horizontal plate. All four support rods are fixedly connected to the workbench.

[0026] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0027] like Figure 1-5 As shown, the H-shaped steel structure beam straightening device of this utility model includes a workbench 1, a transmission assembly on the top surface of the workbench 1, a moving platform 2 on the transmission assembly, two strip slide rails 3 distributed front and back on the top surface of the moving platform 2, two sliding blocks 4 distributed left and right on the two strip slide rails 3, and a locking bolt 5 is installed in front of each sliding block 4.

[0028] Each of the sliding blocks 4 is provided with a spring-loaded assembly, and a U-shaped support plate 6 is installed on the spring-loaded assembly. Each of the U-shaped support plates 6 is threaded with adjusting screws 7 at the front and back. Each adjusting screw 7 is rotatably mounted with a clamping plate 8. The bottom surface of each clamping plate 8 is in sliding contact with the U-shaped support plate 6. A straightening assembly is installed on the top surface of the workbench 1.

[0029] The working principle is as follows: Based on the model of the H-shaped steel structure, the arc block 4 moves along the strip slide rail 3, which in turn moves the U-shaped support plate 6, thereby adjusting the distance between the two U-shaped support plates 6 to accommodate different models of H-shaped steel structures. Then, the two ends of the H-shaped steel structure are placed on the U-shaped support plates 6 respectively, and the adjusting screw 7 is rotated, which moves the clamping plate 8. The clamping plate 8 clamps and fixes the two ends of the H-shaped steel beam structure. Then, the straightening component straightens the H-shaped steel structure. During the straightening process, the two ends of the H-shaped steel structure extend, and under the elastic force of the spring component, the U-shaped support plate 6 moves, thereby avoiding damage to the U-shaped support plate 6 caused by the extended H-shaped steel structure.

[0030] like Figure 3As shown, the transmission assembly includes two left-right distributed fixed plates 9, which are fixedly connected to the worktable 1. A servo motor 10 is mounted on one side of one of the fixed plates 9, and a lead screw 11 is mounted on one end of the shaft of the servo motor 10. The lead screw 11 is rotatably connected to the other fixed plate 9, and passes through the moving platform 2 and is threadedly connected to the moving platform 2. When the servo motor 10 operates, it drives the lead screw 11 to rotate. The rotation of the lead screw 11 drives the moving platform 2 to move along the lead screw 11, thereby moving the H-shaped steel structure and enabling straightening of different positions of the H-shaped steel structure.

[0031] like Figure 1 and 3 As shown, a limiting rod 12 is slidably mounted on the mobile platform 2, and both ends of the limiting rod 12 are fixedly connected to two fixed plates 9 respectively. The limiting rod 12 provides a rectangular limiting function for the mobile platform 2, ensuring that the mobile platform 2 always moves along the lead screw 11.

[0032] like Figure 4-5 As shown, the rebound assembly includes:

[0033] The top surface of each sliding block 4 has two strip grooves 13 distributed front and back. Each strip groove 13 is equipped with a guide rod 16, and each guide rod 16 is slidably installed with a connecting block 17.

[0034] A strip block 18 is installed between the top surfaces of the two connecting blocks 17 located on the same sliding block 4. Each strip block 18 is fixedly connected to the corresponding U-shaped support plate 6. A spring 19 is fitted around one end of each guide rod 16. One end of each spring 19 is connected to the strip groove 15, and the other end of each spring 19 is connected to the connecting block 17. When the U-shaped support plate 6 is subjected to an extension thrust, the U-shaped support plate 6 drives the strip block 18 to move. The movement of the strip block 18 drives the connecting block 17 to move along the guide rod 16, and the spring 19 is compressed, thereby preventing the U-shaped support plate 6 from being damaged by the extension thrust.

[0035] like Figure 3 As shown, the straightening assembly includes a horizontal plate 20, with support rods 21 installed at each of the four corners of the bottom surface of the horizontal plate 20. All four support rods 21 are fixedly connected to the workbench 1. A hydraulic telescopic rod 22 is installed on the horizontal plate 20, and a pressure plate 23 is installed at the free end of the hydraulic telescopic rod 22. The hydraulic telescopic rod 22 extends downwards, causing the pressure plate 23 to move downwards. The pressure plate 23 contacts the H-shaped steel structure and applies pressure to straighten the H-shaped steel structure.

[0036] like Figure 1-3As shown, support legs 24 are installed at the four corners of the bottom surface of the workbench 1, and a support plate 25 is installed at the bottom end of each support leg 24. The bottom surface of each support plate 25 is rough. Through the cooperation of the support legs 24 and the support plates 25, the workbench 1 can be supported. The rough bottom surface of the support plate 25 increases the friction of the support plate 25 and improves the stability of the device.

[0037] like Figure 1-3 As shown, a support block 26 is installed on the top surface of the mobile platform 2. The support block 26 provides support for the H-shaped steel structure, thereby ensuring the completion of the straightening operation.

[0038] This solution also includes a controller, the location of which is set by the staff according to the actual situation during operation. The controller is used to control the electrical components used in this solution. The controller is one of an Intel processor, AMD processor, PLC controller, ARM processor, or microcontroller. It is used in conjunction with a motherboard, memory module, storage medium, and power supply, which is AC power or lithium battery. When a display screen is provided, a display card is also provided. For the operating principle of the controller, please refer to "Automatic Control Principles", "Microcontroller Principles and Application Simulation Cases", and "Sensor Principles and Applications" published by Tsinghua University Press. Other books in this field can also be consulted. Other automation control and electrical components not mentioned are knowledge well known to those skilled in the art and will not be described in detail here.

[0039] Working principle:

[0040] When using this device, firstly, according to the model of the H-shaped steel structure, the arc block 4 is moved along the strip slide rail 3, which in turn moves the U-shaped support plate 6, thereby adjusting the distance between the two U-shaped support plates 6 to accommodate different models of H-shaped steel structures. Then, both ends of the H-shaped steel structure are placed on the U-shaped support plates 6, and the adjusting screw 7 is rotated, which moves the clamping plate 8, clamping and fixing the two ends of the H-shaped steel beam structure. Then, the straightening component straightens the H-shaped steel structure. During the straightening process, both ends of the H-shaped steel structure extend, and under the elastic force of the spring component, the U-shaped support plate 6 moves, thus preventing the extended H-shaped steel structure from damaging the U-shaped support plate 6. The servo motor 10 works, driving the lead screw 11 to rotate. The rotation of the lead screw 11 drives the moving platform 2 to move along the lead screw 11, thereby moving the H-shaped steel structure and enabling straightening of different positions of the H-shaped steel structure.

[0041] This invention utilizes a transmission component to drive a mobile platform to move left and right, thereby moving the structural steel in the same direction and enabling straightening of the steel at different positions. The combination of a strip rail, sliding block, and locking bolt allows adjustment of the U-shaped support plate, accommodating different types of structural steel and improving the device's applicability. Furthermore, a spring-loaded component ensures that during straightening, the ends of the structural steel push the U-shaped support plate forward under its elastic force, preventing damage to the support plate during straightening and ensuring smooth operation.
