Description

Technical Field

[0001] The utility model relates to the technical field of steel structure butt joint, in particular to an automatic butt joint and locking connection device for building steel structures. Background Technique

[0002] In the construction industry, steel structures are widely used due to their high strength, fast construction speed, recyclability and other advantages. However, most traditional steel structure butt joint and locking connection methods rely on manual operation, resulting in problems such as low work efficiency, difficult to guarantee butt joint accuracy, and easy to cause damage to steel structures during installation. Specifically, traditional connection methods usually require a large number of fasteners such as bolts and nuts, which not only have a cumbersome installation process, but also consume a large amount of manpower and material resources. In addition, due to the errors of manual operation, it is often difficult to ensure the accuracy and stability of the butt joint, thus affecting the safety and durability of the entire building structure.

[0003] To solve the above problems, some semi-automatic butt joint and locking devices have emerged on the market. However, these devices often have a single function and can only achieve simple clamping and fixing, and cannot achieve precise adjustment and pre-locking of the position and angle of the steel structure. At the same time, these devices often lack protection for the steel structure during the clamping process, easily causing scratches or deformation on the surface of the steel structure. In addition, due to the lack of effective monitoring means, these devices are often difficult to monitor the position and state of the steel structure in real time during the butt joint and locking process, thus affecting the installation accuracy and efficiency. Therefore, there is an urgent need to improve an automatic butt joint and locking connection device for building steel structures. Content of the Utility Model

[0023] To further understand the features, technical means, specific purposes, and functions achieved by the present utility model, the following will make a more detailed description of the present utility model in conjunction with the accompanying drawings and specific implementation manners.

[0024] Example 1: Please refer to Figures 1-4 , the present utility model provides a technical solution: An automatic docking and locking connection device for building steel structures, including a base 1, a control device 11 is arranged in the base 1, universal wheels 2 are movably arranged at the bottom end of the base 1, and a multi-axis drive assembly 3 for changing the position of the steel structure is arranged at the top end of the base 1.

[0025] The multi-axis drive assembly 3 includes multiple groups of rotating shafts movably arranged at the top end of the base 1, and an electric rotating seat 37 for rotating the steel structure is arranged outside one group of rotating shafts. Through the setting of the multi-axis drive assembly 3, the flexible adjustment of the position of the steel structure is realized, the convenience and accuracy of installation are improved, and at the same time, the control device 11 and the universal wheels 2 in the base 1 make the whole device easy to operate and move.

[0026] Furthermore, the multi-axis drive assembly 3 includes a first movable seat 31 in the base 1, and the first movable seat 31 is connected to the output end of the control device 11. A first rotating shaft 32 is rotatably arranged inside the first movable seat 31. A second movable seat 33 is arranged on the side of the first rotating shaft 32 away from the first movable seat 31. A second rotating shaft 34 is rotatably arranged in the second movable seat 33. A first mounting seat 35 is arranged on the side of the second rotating shaft 34 away from the second movable seat 33. A first connecting frame 36 is arranged outside the first mounting seat 35, and the electric rotating seat 37 is arranged in the first connecting frame 36. The multi-directional movement and rotation of the steel structure are realized, and the setting of the electric rotating seat 37 further enhances the flexibility of angle adjustment.

[0027] Further, a clamping assembly 4 for clamping the steel structure to be docked is provided outside the electric rotating seat 37. The clamping assembly 4 includes a mounting shell 41 provided outside the electric rotating seat 37. A mounting plate 42 is provided on the side of the mounting shell 41 away from the electric rotating seat 37. A driving device 43 is provided in the mounting shell 41. The output end of the driving device 43 is drivingly connected to a first gear 44. Two groups of second gears 45 are rotatably provided outside the mounting plate 42. A second connecting frame 46 is fixed outside each group of second gears 45. A clamping plate 48 for clamping the steel structure is provided in the second connecting frame 46. The setting of the clamping assembly 4 realizes the stable clamping of the steel structure. Through the transmission of the driving device 43, the first gear 44 and the second gears 45, and the cooperation of the second connecting frame 46 and the clamping plate 48, the precise control of the clamping action is realized.

[0028] Further, the first gear 44 is in a meshing state with one of the second gears 45, and the two groups of second gears 45 mesh with each other. The meshing design of the first gear 44 and the second gears 45 realizes the effective transmission of power, and the meshing of the two groups of second gears 45 ensures the synchronism and stability of the clamping action.

[0029] Further, the clamping assembly 4 further includes two groups of third connecting frames 47 rotatably provided outside the mounting plate 42. Each group of third connecting frames 47 is respectively rotatably connected to one of the clamping plates 48. The setting of the third connecting frame 47 enhances the rotational stability of the clamping plate 48, making the clamping action more reliable.

[0030] Embodiment 2: Please refer to Figure 5 and, in combination with Embodiment 1, it is further obtained that a pre-locking assembly 5 for positioning the steel structure is provided outside the mounting shell 41. The pre-locking assembly 5 includes a second mounting seat 51 provided at the top of the mounting shell 41. An electric telescopic rod 52 is provided in the second mounting seat 51. A docking plate 53 for pre-positioning the steel structure is provided at the output end of the electric telescopic rod 52. The setting of the pre-locking assembly 5 realizes the pre-positioning and preliminary locking of the steel structure. Through the cooperation of the electric telescopic rod 52 and the docking plate 53, the stability and accuracy of the steel structure during the docking process are ensured.

[0031] Further, the docking plate 53 is initially located beside the clamping assembly 4, and a rubber pad is fixed on the side of the docking plate 53 away from the output end of the electric telescopic rod 52. The setting of the initial position of the docking plate 53 and the rubber pad not only avoids the interference of the docking plate 53 on the clamping assembly 4, but also protects the steel structure from damage.

[0032] Furthermore, the pre-locking assembly 5 further includes a third mounting seat 54 disposed beside the mounting shell 41, and a position sensor 55 for detecting the position of the steel structure is disposed in the third mounting seat 54. The setting of the position sensor 55 realizes the real-time monitoring of the position of the steel structure, ensures the precise control of the docking and locking process, and improves the accuracy and efficiency of installation.

[0033] During the actual operation process, when it is necessary to dock and lock the steel structure, the operation steps are as follows: First, start the driving device 43 to drive the first gear 44 to rotate. The rotation of the first gear 44 will drive a set of second gears 45 meshing with it to rotate, and the rotation of this set of second gears 45 will cause the rotation of another set of second gears 45. The synchronous rotation of the two sets of second gears 45, through the transmission of the second connecting frame 46 and the third connecting frame 47, causes the two sets of clamping plates 48 to rotate and clamp the steel structure to be locked.

[0034] After the clamping is completed, by operating the control device 11, the first movable seat 31 and the second movable seat 33 are rotated, thereby driving the first rotating shaft 32 and the second rotating shaft 34 to rotate, so as to change the position of the clamped steel structure and send it to the position to be docked. At the same time, operate the electric rotating seat 37 to rotate the mounting shell 41, precisely adjust the angle of the steel structure, and fix it in the accurate position to ensure that the connection points are aligned. When the steel structure approaches the predetermined position, the position sensor 55 will send a signal to prepare to enter the locking stage. At this time, open the electric telescopic rod 52 to apply sufficient pressure to the steel structure by the docking plate 53 to ensure the stability of the connection part and prevent the connection from loosening due to external force or vibration. The rubber pad outside the docking plate 53 can also avoid damaging the steel structure. Subsequently, use high-strength bolts to reinforce the connection points to ensure that the connection part is firm and reliable. During the fixing process, the position sensor 55 will detect the connection position of the steel structure in real time to ensure that the locking strength meets the design requirements. Once the position sensor 55 confirms that the connection part is stable and the position is accurate, the installation work of the steel structure enters the next stage. If more installations are required, the above operations can be repeated to quickly reconfigure to a new connection point to achieve the continuous and efficient installation of the steel structure.

[0035] The above embodiments only represent one or several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
