[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-4, a stable column foot positioning mechanism for steel structure construction, including a column foot body 1, a positioning box 2, a positioning plate 3, a positioning device and a guide device, the top of the positioning plate 3 is installed with the positioning box 2, the top of the positioning box 2 is provided with a mounting groove 4, the mounting groove 4 is adapted to the column foot body 1, the top wall of the positioning box 2 is installed with the guide device, the positioning device includes a square groove 5, a positioning block 6, a positioning groove 7, a slider 8, a slide groove 9, a first spring 10, a movable plate 11, a fixed frame 12, a bidirectional screw 13, a square nut 14 and a drive shaft 15, the left and right ends of the positioning box 2 are provided with the square groove 5 that passes through the mounting groove 4, the positioning block 6 is slidably installed in the square groove 5, the column foot body 1 The left and right ends are provided with the positioning grooves 7, the positioning blocks 6 are adapted to the positioning grooves 7, the front and rear ends of the square groove 5 are provided with the slide grooves 9, the sliders 8 are slidably installed in the slide grooves 9, and the two groups of sliders 8 are respectively fixedly installed at the front and rear ends of the positioning block 6, and the first spring 10 for supporting the slider 8 is installed in the slide groove 9. One end of the positioning box 2 is embedded with the fixed frame 12 with a side opening, and the bidirectional screw 13 is rotatably installed in the fixed frame 12. One end of the bidirectional screw 13 passes through the fixed frame 12 and is installed with the drive shaft 15. Both ends of the bidirectional screw 13 are threadedly installed with the square nuts 14, and the two groups of positioning blocks 6 are away from the positioning grooves 7. The movable plate 11 is installed at one end, and the side walls of one end of the two groups of movable plates 11 are fixedly connected to the corresponding side walls of the square nuts 14. In this embodiment, when in use, first fix the positioning plate 3 to the target position by bolts and other parts, and then place the column foot body 1 through the guide device in the mounting groove 4 at the top of the positioning box 2 (in the initial state, the positioning block 6 is in the square groove 5 under the connection and limiting action with the movable plate 11, and does not contact the positioning groove 7 on the column foot body 1). At this time, the bottom of the column foot body 1 contacts the bottom of the mounting groove 4, and the positioning groove 7 of the column foot body 1 is aligned with the positioning block 6 in the positioning box 2. The bidirectional screw 13 is driven to rotate by rotating the drive shaft 15, and the rotation of the bidirectional screw 13 will cause the square nuts at both ends to rotate. 14 moves toward the center, and the movement of the two sets of square nuts 14 toward the center will drive the movable plate 11 fixed thereto to move together, thereby driving the positioning block 6 to slide in the square groove 5, and the positioning block 6 moves in the direction of the column body 1. During the movement of the positioning block 6 in the square groove 5, the slider 8 is driven to slide in the slide groove 9, and the compressed first spring 10 is gradually released until the positioning block 6 completely enters the positioning groove 7 on the column body 1. When the positioning block 6 completely enters the positioning groove 7, the positioning block 6 is supported by the first spring 10 and remains in the positioning groove 7, thereby achieving a stable fixation of the column body 1. When the column body 1 and the positioning box 2 need to be disassembled, it is only necessary to rotate the drive shaft 15 in the opposite direction so that the drive shaft 15 drives the bidirectional screw 13 to rotate in the opposite direction.The two square nuts 14 will move to the sides, and the movement of the square nuts 14 to the sides will drive the movable plate 11 fixed thereto to move outward, thereby pushing the positioning block 6 to move outward. The positioning block 6 drives the slider 8 to slide in the slide groove 9 and compresses the first spring 10. When the positioning block 6 moves outward to a certain distance, the positioning block 6 will disengage from the positioning groove 7 on the column foot body 1, causing the positioning block 6 to return to its initial position. After confirming that the positioning block 6 has completely disengaged from the positioning groove 7 and returned to its initial position, the positioning block 6 no longer exerts any constraint on the column foot body 1. After confirming that the positioning block 6 has disengaged from the positioning groove 7, the column foot body 1 can be safely removed from the mounting slot 4.

[0026] During actual use, the installation of the column leg body 1 is further guided. In this embodiment, the guide device includes a guide seat 16, a groove 17, a second spring 18, a U-shaped frame 19 and a roller 20. The guide seat 16 is installed on the top walls of the front, back, left and right directions of the positioning box 2. The guide seat 16 is provided with three groups of grooves 17 at one end close to the column leg body 1. Multiple groups of second springs 18 are installed in the three groups of grooves 17. The U-shaped frame 19 is fixedly installed at the end of the second spring 18. The roller 20 is rotatably installed in the U-shaped frame 19. When the column leg body 1 is not installed, the roller 20 in the U-shaped frame 19 extends out of the groove 17 of the guide seat 16 under the action of the second spring 18. At this time, the roller 20 is in the outermost position. When the column leg body 1 approaches the positioning box 2, the roller 20 first contacts the surface of the column leg body 1. Due to the outward extension of the roller 20, it can make preliminary contact and guide the column leg body 1. As the column foot body 1 continues to be placed downward, the roller 20 will gradually retract into the groove 17 under the action of the second spring 18. While retracting, the roller 20 will generate a certain pressure on the surface of the column foot body 1 to help the column foot body 1 maintain the correct direction and position. The design of the roller 20 allows it to roll freely on the surface of the column foot body 1, which can reduce friction, and when the column foot body 1 deviates slightly from the correct position, the roller 20 can help the column foot body 1 automatically adjust to the correct position through its rolling. When the column foot body 1 fully enters the installation groove 4, the roller 20 remains in contact with the column foot body 1 under the action of the second spring 18, and continues to provide guidance and support to ensure that the column foot body 1 will not deviate during the subsequent positioning and fixing process. The guiding device can effectively assist the installation of the column foot body 1, ensuring that it enters the installation groove 4 accurately and maintains the correct posture, thereby improving the reliability and efficiency of the column foot positioning mechanism of the entire steel structure construction.

[0027] During actual use, it is further convenient to guide the movement of the movable plate 11. In this embodiment, the positioning box 2 is equipped with a guide frame 21 with a side opening at the end away from the fixed frame 12, and the guide rod 22 is fixedly installed in the guide frame 21. Guide blocks 23 are slidably installed at both ends of the guide rod 22. The end of the movable plate 11 away from the square nut 14 is fixedly connected to the corresponding side wall of the guide block 23. The combination of the guide rod 22 and the guide block 23 provides a precise linear motion trajectory for the movable plate 11. The guide block 23 slides on the guide rod 22 to ensure that the movement direction of the movable plate 11 is always along the expected path, thereby improving the positioning accuracy. The guide rod 22 and guide block 23 structure in the guide frame 21 can effectively constrain the movement of the movable plate 11, reduce the offset or shaking of the movable plate 11 caused by external interference or mechanical vibration, and enhance the stability of the system.

[0028] During actual use, it is further convenient to guide the positioning of the column foot body 1. In this embodiment, the corner of the top of the guide seat 16 close to the column foot body 1 is rounded. The rounded corner design can reduce the hard contact between the column foot body 1 and the guide seat 16, avoiding scratches or damage caused by sharp corners during the installation of the column foot body 1. The rounded corner design also allows the column foot body 1 to transition more naturally when approaching the guide seat 16, avoiding sudden stops or jams caused by right-angle edges, and making it easier for the column foot body 1 to slide into the predetermined position.

[0029] During actual use, the friction between the slider 8 and the slide groove 9 is further reduced. In this embodiment, the slide groove 9 and the slider 8 are both cylindrical in design. The cylindrical design can provide a more uniform contact area compared to other shapes (such as rectangles), which helps to reduce the friction when the slider 8 moves in the slide groove 9, making the sliding smoother.

[0030] During actual use, the slider 8 is further guided. In this embodiment, a fixed rod 24 is fixedly installed in the slide groove 9. The fixed rod 24 and the slider 8 are slidably connected. The sliding connection between the fixed rod 24 and the slider 8 can provide an additional guiding mechanism to ensure that the linear motion of the slider 8 in the slide groove 9 is smoother, reducing the shaking or deviation of the slider 8 during movement. The presence of the fixed rod 24 can help the slider 8 move more accurately along the slide groove 9, reduce the positioning error caused by the uneven surface of the slide groove 9 or the deformation of the slider 8 itself, and improve the overall positioning accuracy.

[0031] In actual use, it is further convenient to drive the drive shaft 15. In this embodiment, a hand wheel 25 is installed at the end of the drive shaft 15. The hand wheel 25 provides a larger contact area, so that the user can hold the rim by hand to rotate it. Compared with directly rotating the drive shaft 15 by hand, this method is more labor-saving and convenient.

[0032] During actual use, in order to further improve the anti-slip property of the hand-cranked wheel 25, in this embodiment, the hand-cranked wheel 25 is provided with anti-slip grooves, which can increase the friction coefficient of the surface of the hand-cranked wheel 25, making it easier for the user to feel the sense of control when rotating the hand-cranked wheel 25, thereby improving the comfort and accuracy during operation.

[0033] In order to explain in detail the possible application scenarios, technical principles, specific solutions that can be implemented, and the purpose and effects of this application, the following is a detailed description of the specific embodiments listed in conjunction with the accompanying drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of this application and are therefore only examples and are not intended to limit the scope of protection of this application.
