Description

Technical Field

[0001] This utility model relates to the field of flat beam technology, and in particular to a three-dimensional precision docking and assembly device for flat beams. Background Technology

[0002] In ordinary beam-frame structures, the beam's cross-sectional height is generally greater than its cross-sectional width. The reinforcement bars in the core area of ​​the frame joints are densely packed and interwoven, making construction difficult and compromising the quality of joint construction. Furthermore, the high beam cross-sectional height reduces the clear height under the beam, limiting the building's floor height or open space. Therefore, my country's 2010 new code adjusted the height-to-span ratio of main beams from the old code (1 / 8 to 1 / 12) to (1 / 10 to 1 / 18), indicating that the code advocates the design and application of wide, flat beam floor slabs.

[0003] In modern construction engineering, especially in bridge construction and large steel structure projects, flat beams are widely used due to their excellent mechanical properties and space-saving advantages. However, the butt joint assembly of flat beams is a critical step in the construction process, requiring extremely high precision and efficiency.

[0004] Traditional flat beam butt joint assembly methods mainly rely on manual measurement, positioning, and fixing, which has many problems. First, manual measurement has a large error, making it difficult to meet the requirements of high-precision construction. It can easily lead to deviations in the horizontal, vertical, and axial directions of the flat beam, affecting the stability and load-bearing capacity of the overall structure. Second, manual operation is inefficient, requiring a lot of time and manpower, which increases construction costs. Therefore, we propose a three-dimensional precision butt joint assembly device for flat beams. Utility Model Content

[0029] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] In this embodiment, the flat beam docking limiting assembly 2 includes a sliding limiting plate 21, a spring 22, a second rotating shaft 23, and a locking block 24. The sliding limiting plate 21 is slidably installed on the inner side of the movable frame 3. One end of the spring 22 is fixedly installed on the bottom of the movable frame 3, and the other end of the spring 22 is fixedly installed on the bottom inner wall of the sliding limiting plate 21. The second rotating shaft 23 is rotatably installed on the top of the movable frame 3, and the locking block 24 is fixedly installed on the top of the second rotating shaft 23. The locking block 24 can rotate above the second rotating shaft 23, so that after the sliding limiting plate 21 is in contact with the ground, the locking block 24 can limit and lock the sliding limiting plate 21, so that the sliding limiting plate 21 will not be displaced during the limiting process, and the movable frame 3 will not move during use.

[0035] In this embodiment, the flat beam docking limiting assembly 2 also includes a second motor 25, a drive shaft 26, and a transmission gear 27.

When the laser positioning line signal received by the laser receiver is inconsistent with the preset assembly position signal, the external controller can drive multiple adjustment structures to adjust according to the position deviation of the flat beam until the flat beam reaches the precise docking and assembly position.

[0038] In this embodiment, both the reinforcing rib 6 and the support frame 15 are X-shaped, and both are made of steel. The steel reinforcing rib 6 and the support frame 15 make the device more stable during use and prevent the flat beam from crushing the device.

[0039] The specific operation is as follows: the movable frame 3 and the reinforcing rib 6 ensure the stability of the entire device, the pulley 5 facilitates the movement and positioning of the device on the construction site, and when the device is moved to the designated position, the sliding limit plate 21 can be pressed down to lower it, so that the sliding limit plate 21 and its bottom anti-slip pad contact the ground. The rotating locking block 24 limits the sliding limit plate 21, so that the sliding limit plate 21 can always contact the ground for limitation, thereby locking the position of the device and providing a reference for the initial positioning of the flat beam.

[0040] A mounting groove 10 is provided above the rotating disk 8. A lead screw 12 is rotatably installed inside the mounting groove 10. The lead screw 12 can drive the moving plate 13 to move. The second motor 25 below can drive the auxiliary shaft 7 and the rotating disk 8 to rotate through the drive shaft 26 and the transmission gear 27. After the rotating disk 8 rotates, the position of the flat beam in the horizontal X and Y axis directions can be adjusted. Vertical adjustment is achieved by a hydraulic telescopic rod 14. A bearing platform 16 is installed on the top of the hydraulic telescopic rod 14 for placing the flat beam. By controlling the lifting and lowering of the hydraulic telescopic rod 14, the height of the flat beam in the vertical Z axis direction can be adjusted. The position and angle of the flat beam in three-dimensional space can be precisely controlled.

[0041] The positioning block 19 is used for the initial positioning of the flat beam. After the flat beam is placed on the bearing platform 16, the flat beam abuts against the positioning block 19 to achieve the initial positioning of the flat beam. The electric telescopic rod 17 is controlled to drive the clamping block 18 to move. The clamping block 18 can clamp and fix the flat beam. The clamping block 18 is made of rubber, which can avoid damage to the surface of the beam when clamping the flat beam and ensure that the flat beam will not be displaced during the assembly process.

[0042] The laser positioner 20 includes multiple laser emitters and laser receivers; the laser emitters are installed at the top four corners of the mobile frame 3 to emit laser positioning lines; the laser receivers are installed above the support platform 16 and can receive the laser positioning line signals emitted by the laser emitters; the laser positioner 20 is connected to an external controller of the first motor 11 and the second motor 25. When the laser positioning line signal received by the laser receiver is inconsistent with the preset assembly position signal, the external controller can drive multiple adjustment structures to adjust according to the position deviation of the flat beam until the flat beam reaches the precise docking and assembly position.
