Description

Technical Field

[0001] This utility model relates to the technical field of steel structures, and in particular to a positioning device for assembling box-type columns of steel structures. Background Technology

[0002] Positioning is required during the assembly of steel structure box columns, followed by welding and assembly. Chinese invention patent application CN113210984A discloses a box column assembly machine. This machine includes an equipment platform equipped with a positioning mechanism, a vertical clamping mechanism, and a horizontal clamping mechanism. The vertical and horizontal clamping mechanisms are located on either side of the positioning mechanism. The vertical clamping mechanism clamps downwards from above the positioning mechanism, while the horizontal clamping mechanism clamps horizontally from the side of the positioning mechanism. The positioning and horizontal clamping mechanisms are mounted on the equipment platform via guide rails. This assembly machine solves the problem of steel plate deformation after cutting, improves the quality of the finished box columns, has high production efficiency, low processing costs, is suitable for mass production, and can be freely combined according to the size of the box columns produced, making it widely applicable.

[0003] However, the positioning wall plate and positioning base plate of the positioning mechanism of the above-mentioned assembly machine are fixed. Since the positioning wall plate is always vertical, the operation of placing the plate onto the positioning wall plate is relatively complicated, and the plate is prone to tipping over onto the positioning base plate during the positioning process, resulting in poor stability. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a steel structure box column assembly and positioning device that uses a tiltable and flip-up positioning mechanism to support and position the side wall panels of the steel structure box column, thereby reducing the risk of the side wall panels tipping over and improving stability.

[0005] This utility model discloses a steel structure box-type column assembly and positioning device, including a base plate; it also includes two positioning base plates, four rotating shafts, four shaft seats, two limiting seats, two positioning wall plates, and two push cylinders. The two positioning base plates are respectively arranged opposite each other on the left and right sides above the base plate. Rotating shafts are installed on the front and rear side walls of the outer ends of the two positioning base plates. The four rotating shafts are rotatably connected to the four shaft seats, which are mounted on the base plate. Limit seats are installed at the front ends of the two positioning base plates. The two positioning wall plates are respectively mounted on the two positioning base plates and are arranged perpendicular to the two positioning base plates. The two push cylinders are fixed. The fixed ends are rotatably connected to the left and right ends of the base plate, respectively, and the piston rod ends of the two push cylinders are rotatably connected to the outer walls of the two positioning wall plates, respectively. The two positioning base plates are used to support one base plate of the steel structure box column, and the inner walls of the two positioning wall plates are used to support the two side wall plates of the steel structure box column, respectively. During operation, the piston rods of the two push cylinders retract, causing the two positioning wall plates to flip outwards and the two positioning base plates to tilt upwards, so that the two positioning base plates and the two positioning wall plates are arranged in a W shape. At this time, the two side wall plates of the steel structure box column are placed on the inner walls of the two positioning wall plates, respectively. The lower edges of the side wall panels contact the two positioning base plates respectively. The positions of the two side wall panels are adjusted and fixed. One base plate of the steel structure box column is placed on the two positioning base plates, so that the inner edges of the two positioning base plates support the lower end face of one base plate of the steel structure box column. The piston rods of the two push cylinders extend, pushing the two positioning wall panels back to a vertical state, and the two positioning base plates back to a horizontal state, so that the two positioning base plates support the base plate. During this process, the ends of the base plates are limited and positioned by the two limiting seats. When the two positioning wall panels are completely vertically reset, the two side edges of the base plates on the two positioning base plates... The bottom plate is pressed firmly against the lower edges of the two side wall panels. The welding equipment is used to weld the joint between the bottom plate and the two side wall panels. The other bottom plate is placed between the two positioning wall panels, and the two sides of the other bottom plate are aligned with the upper edges of the two side wall panels. The welding equipment is used to weld the joint between the other bottom plate and the two side wall panels. The assembly, positioning and welding of the steel structure box column is completed. Compared with the existing technology, which uses a tiltable and flip-out positioning mechanism for the bottom plate and side wall panels to support and position the side wall panels of the steel structure box column, the side wall panels will not tip over onto the positioning bottom plate. The operation is simplified and the stability is better.

[0006] Preferably, the system also includes two carriages, multiple adsorption components, and two push cylinders. The two carriages are slidably mounted on the two positioning wall plates, and multiple adsorption components are installed on each carriage. The fixed ends of the two push cylinders are respectively mounted on the two positioning wall plates, and the piston rods of the two push cylinders are respectively connected to the two carriages. The multiple adsorption components are magnetic seats or electromagnetic blocks. When the two side wall plates are placed on the inner walls of the two positioning wall plates, the multiple adsorption components adsorb the two side wall plates respectively. The piston rods of the two push cylinders retract and drive the two carriages to move along the positioning wall plates respectively, thereby adjusting the relative positions of the two side wall plates with the two positioning wall plates and the two positioning base plates, and completing the positioning of the two side wall plates. The adsorption effect of the multiple adsorption components further prevents the two side wall plates from tipping over to the two positioning base plates, improving stability.

[0007] Preferably, it also includes two support plates, which are installed in the middle of the upper surface of the base plate and support the inner ends of the two positioning base plates respectively; when the two positioning base plates are flat, the two support plates support the inner ends of the two positioning base plates respectively, thereby improving the stability of the two positioning base plates.

[0008] Preferably, it also includes two pads, which are detachably installed on the two limit seats respectively; the two pads are placed between the base plate and the two limit seats respectively to reduce the impact damage to the two limit seats, and after a period of operation, it is convenient to replace the pads that have been damaged by impact, thus improving practicality.

[0009] Preferably, it also includes two slide rails, which are mounted on the base plate and arranged perpendicularly to the two positioning base plates. Four bearing seats are slidably mounted on the two slide rails respectively. After the two positioning base plates are flattened, the piston rods of the two push cylinders continue to extend, thereby pushing the two positioning wall plates and the two positioning base plates to drive the two bearing seats to approach along the two slide rails respectively, so that the two side edges of the base plate press against the lower edges of the two side wall plates respectively, adapting to base plates of different widths and improving versatility.

[0010] Preferably, it also includes a transverse slide groove, a slide rod, a spring, a longitudinal slide groove, a push block, and an elastic rod. A transverse slide groove is provided at the end of the positioning base plate away from the limiting seat. The slide rod is slidably installed in the transverse slide groove, with its inner end extending out of the inner side of the positioning base plate. One end of the spring is connected to the slide rod, and the other end of the spring is connected to the positioning base plate. A longitudinal slide groove is provided at the end of the positioning base plate away from the limiting seat, and the longitudinal slide groove is arranged along the longitudinal direction of the positioning base plate. The push block is slidably installed in the longitudinal slide groove. One end of the elastic rod is rotatably connected to the slide rod, and the other end of the elastic rod is rotatably connected to the push block. The base plate is placed on two positioning base plates. When the base plate is positioned, it is located between two limiting seats and two push blocks. When the two positioning base plates are relatively close, the two sliding rods engage. As the two positioning base plates continue to move closer, the two sliding rods are compressed into the two transverse sliding grooves respectively. During the compression of the two sliding rods, the two push blocks are pushed along the two longitudinal sliding grooves towards the two limiting seats through the two elastic rods. This causes the two push blocks to push the base plate towards the two limiting seats, pressing and positioning the end of the base plate onto the two limiting seats, thus achieving automatic positioning of the base plate. The two elastic rods are telescopic to adapt to base plates of different lengths, providing good versatility.

[0011] Preferably, the system further includes two slide rails, two sliders, two crossbars, and two laser heads. The two slide rails are respectively mounted on the top of the two positioning wall plates. The two sliders are respectively slidably mounted on the two slide rails. The two crossbars are respectively slidably mounted on the two sliders. The two laser heads are respectively mounted on the two crossbars. The two sliders move along the two slide rails. The two sliders drive the two laser heads to move through the two crossbars, thereby adjusting the position of the two laser heads. The two laser heads emit laser beams towards the inner walls of the two positioning wall plates and the two positioning base plates. The laser beams are used to mark the end positions of the side wall plates and the base plates, thereby improving the positioning accuracy.

[0012] Compared with the prior art, the advantages of this utility model are as follows: the positioning mechanism of the tiltable and flip-out base plate and side wall plate supports and positions the side wall plate of the steel structure box column, and the side wall plate will not tip over onto the positioning base plate, simplifying the operation and improving stability.

This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0022] Example 1

[0023] like Figures 1 to 4 , Figure 7As shown, the steel structure box column assembly positioning device includes a base plate 1; it also includes two positioning base plates 2, four rotating shafts 3, four shaft seats 4, two limiting seats 5, two positioning wall plates 6, and two push cylinders 10. The two positioning base plates 2 are respectively arranged opposite each other on the left and right sides above the base plate 1. The front and rear side walls of the outer ends of the two positioning base plates 2 are equipped with rotating shafts 3. The four rotating shafts 3 are respectively rotatably connected to the four shaft seats 4. The four shaft seats 4 are installed on the base plate 1. The front end of the two positioning base plates 2 is equipped with limiting seats 5. The two positioning wall plates 6 are respectively installed on the two positioning base plates 2 and are arranged perpendicular to the two positioning base plates 2. The fixed ends of the two push cylinders 10 are respectively connected to the left and right sides of the base plate 1. The system includes two rotating connections at both ends, with the piston rod ends of the two push cylinders 10 rotatably connected to the outer walls of the two positioning wall plates 6 respectively; it also includes two slides 7, multiple suction components 8, and two push cylinders 9. The two slides 7 are slidably mounted on the two positioning wall plates 6 respectively, and multiple suction components 8 are mounted on each of the two slides 7. The fixed ends of the two push cylinders 9 are respectively mounted on the two positioning wall plates 6, and the piston rods of the two push cylinders 9 are respectively connected to the two slides 7; it also includes two support plates 11, which are mounted on the middle of the upper end face of the base plate 1, and support the inner ends of the two positioning base plates 2 respectively; it also includes two pads 12, which are detachably mounted on the two limiting seats 5 respectively.

[0024] Two positioning base plates 2 are used to support one base plate of the steel structure box column, and the inner sidewalls of the two positioning wall plates 6 are used to support the two side wall plates of the steel structure box column respectively. During operation, the piston rods of the two push cylinders 10 retract, causing the two positioning wall plates 6 to flip outwards, and the two positioning base plates 2 to tilt upwards, so that the two positioning base plates 2 and the two positioning wall plates 6 are arranged in a W shape. At this time, the two side wall plates of the steel structure box column are placed on the inner walls of the two positioning wall plates 6 respectively, and the lower edges of the two side wall plates of the steel structure box column contact the two positioning base plates 2 respectively. When the two side wall plates are placed... After being placed on the inner walls of the two positioning wall plates 6, multiple adsorption components 8 respectively adsorb the two side wall plates. The piston rods of the two push cylinders 9 retract, driving the two slides 7 to move along the positioning wall plates 6, thereby adjusting the relative positions of the two side wall plates with the two positioning wall plates 6 and the two positioning base plates 2, thus completing the positioning of the two side wall plates. The adsorption effect of the multiple adsorption components 8 further prevents the two side wall plates from tipping over onto the two positioning base plates 2. One base plate of the steel structure box column is placed on the two positioning base plates 2, so that the inner edges of the two positioning base plates 2 support one base plate of the steel structure box column. On the lower end face, the piston rods of the two push cylinders 10 extend and push the two positioning wall plates 6 back to the vertical state, and the two positioning base plates 2 return to the horizontal state, so that the two positioning base plates 2 support the base plate, and the two support plates 11 support the inner ends of the two positioning base plates 2 respectively. During this process, the ends of the base plates are limited and positioned by the two limiting seats 5. The two pads 12 are respectively placed between the base plate and the two limiting seats 5 to reduce the impact damage to the two limiting seats 5. When the two positioning wall plates 6 are completely vertically reset, the two side edges of the base plates on the two positioning base plates 2 respectively contact the lower ends of the two side wall plates. The edges are pressed together, and the welding equipment is used to weld the joint between the base plate and the two side wall plates. Another base plate is placed between the two positioning wall plates 6, and the two sides of the other base plate are aligned with the upper edges of the two side wall plates respectively. The welding equipment is used to weld the joint between the other base plate and the two side wall plates, thus completing the assembly, positioning and welding of the steel structure box column. Compared with the existing technology that uses a tiltable and flip-out positioning mechanism for the base plate and side wall plates to support and position the side wall plates of the steel structure box column, the side wall plates will not tip over onto the positioning base plate 2, simplifying the operation and improving stability.

It also includes a transverse slide groove 13, a slide rod 14, a spring 15, a longitudinal slide groove 16, a push block 17, and an elastic rod 18. The transverse slide groove 13 is provided on the end of the positioning base plate 2 away from the limiting seat 5. The slide rod 14 is slidably mounted in the transverse slide groove 13, and the inner end of the slide rod 14 extends out of the inner side of the positioning base plate 2. One end of the spring 15 is connected to the slide rod 14, and the other end of the spring 15 is connected to the positioning base plate 2. The longitudinal slide groove 16 is provided on the end of the positioning base plate 2 away from the limiting seat 5.

One end of the elastic rod 18 is rotatably connected to the slide rod 14, and the other end of the elastic rod 18 is rotatably connected to the push block 17.

[0027] After the two positioning base plates 2 are laid flat, the piston rods of the two push cylinders 10 continue to extend, thereby pushing the two positioning wall plates 6 and the two positioning base plates 2 to drive the two shaft seats 4 to move closer along the two slide rails 19 respectively, so that the two side edges of the base plate are pressed into contact with the lower edges of the two side wall plates respectively, adapting to base plates of different widths; when the base plate is placed on the two positioning base plates 2, the base plate is located between the two limit seats 5 and the two push blocks 17. When the two positioning base plates 2 are relatively close, the two slide rods 14 are connected, and the two positioning base plates 2 continue to move closer, so that the two slide rods 14 are compressed into the two transverse slide grooves 13 respectively. During the compression of the two slide rods 14, the two push blocks 17 are pushed along the two longitudinal slide grooves 16 towards the two limit seats 5 by the two elastic rods 18 respectively, so that the two push blocks 17 push the base plate towards the two limit seats 5, so that the end of the base plate is pressed and positioned on the two limit seats 5, realizing the automatic positioning operation of the base plate.

[0030] Two sliders 21 move along two slide rails 20 respectively. The two sliders 21 drive the two laser heads 23 to move through two crossbars 22, thereby adjusting the position of the two laser heads 23. The two laser heads 23 emit laser beams onto the inner walls of the two positioning wall plates 6 and the two positioning base plates 2. The laser beams are used to mark the end positions of the side wall plates and base plates to improve positioning accuracy.

[0031] like Figures 1 to 7 As shown, the steel structure box column assembly and positioning device of this utility model, during operation, firstly, the piston rods of the two push cylinders 10 retract, causing the two positioning wall plates 6 to flip outwards, and the two positioning base plates 2 to tilt upwards, so that the two positioning base plates 2 and the two positioning wall plates 6 are arranged in a W shape.

Then, one base plate of the steel structure box column is placed on the two positioning base plates 2, so that the inner edges of the two positioning base plates 2 support the lower end face of one base plate of the steel structure box column. The piston rods of the two push cylinders 10 extend, pushing the two positioning wall plates 6 back to the vertical state, and the two... The positioning base plate 2 returns to a horizontal state, allowing the two positioning base plates 2 to support the base plate. The two positioning base plates 2 are relatively close, and the two sliding rods 14 are connected. The two positioning base plates 2 continue to move closer, causing the two sliding rods 14 to compress into the two transverse sliding grooves 13 respectively. During the compression of the two sliding rods 14, the two push blocks 17 are pushed along the two longitudinal sliding grooves 16 to the two limiting seats 5 through the two elastic rods 18 respectively.
