Description

Technical Field

[0001] The utility model belongs to the field of portable construction engineering, and in particular relates to an assembled building hoisting and placing device with a positioning structure. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. In the prior art, when assembling building components, it is necessary to accurately insert the embedded positioning steel bars on the construction layer into the reserved steel bar holes at the bottom of the building components. However, during the final installation, the reserved steel bar holes are usually placed under the building panels and the building panels have a large deadweight, resulting in the need to insert the positioning steel bars into the reserved steel bar holes. This positioning process requires repeated adjustments, is extremely difficult to operate, and is time-consuming, and has high labor costs. Utility Model Content

[0003] In order to overcome the problem that during the process of hoisting, installing and positioning the prefabricated building, the building panels have a large dead weight and the reserved steel bar holes are located at the bottom, which makes it inconvenient to position the building panels and to observe the insertion situation between the ground positioning steel bars and the reserved steel bar holes, resulting in the need for workers to make repeated adjustments, which is time-consuming and labor-intensive.

[0005] Preferably, the device is installed on the ground at the connection of the portable building board. By rotating the first rotating component, the second rotating component is driven to rotate, thereby adjusting the distance between the two positioning components, making positioning restrictions, and then pulling out the reflector on the limiting component. When the portable building board needs to be installed, the rolling component is contacted with the building board, and the positioning component limits the portable building board by observing the limiting component, thereby solving the problem of repeated adjustments during the installation of the portable building board, which is time-consuming and labor-intensive.

[0006] Preferably, the limiting assembly includes a shell, a first through hole, a second through hole, a limiting block, a limiting column, a limiting groove, a first groove body and a reflector; the first through hole and the second through hole are penetrated through the outer walls at both ends of the shell; the limiting blocks and the limiting columns are fixedly connected to the left and right ends of the shell; the limiting groove is provided at the front end of the limiting block; the first groove body is penetrated through the front end of the shell; the reflector is movably installed on the inner wall of the first groove body, and when the portable building panel is located at the front end of the shell, the reflector is pulled out of the first groove body and placed under the building panel, and the insertion condition between the positioning steel bar and the reserved steel bar hole on the building panel is corrected by the content reflected by the reflector, thereby realizing the rapid correction and installation of the prefabricated building panel.

[0007] Preferably, the rolling assembly includes an ear plate and a roller; two ear plates are fixedly connected to the upper end of the shell; the roller is rotatably installed at one end of the two ear plates close to each other, and when the portable building board moves downward, the portable building board can descend more stably through contact with the outer wall of the roller.

[0008] Preferably, the first rotating assembly includes a rotating rod and a first gear; the rotating rod is rotated on the inner wall of the first through hole; the first gear is fixedly connected to the outer wall of the rotating rod; the first gear is located inside the shell, and the first gear on the outer wall of the rotating rod can be rotated by rotating the rotating rod on the inner wall of the first through hole.

[0009] Preferably, the second rotating assembly includes a double-thread screw and a second gear; the double-thread screw is rotatably mounted on the inner wall of the second through hole; the second gear is fixedly connected to the outer wall of the double-thread screw; two opposite screw grooves are provided on the double-thread screw; the outer wall of the second gear is meshed with the outer wall of the first gear, and when the first gear rotates, the outer wall of the first gear and the outer wall of the second gear are in a meshing structure, thereby driving the second gear to rotate, and when the second gear rotates, it drives the double-thread screw to rotate on the inner wall of the second through hole.

[0010] Preferably, the positioning assembly includes a first fixed block, a second fixed block, a limiting hole, a screw groove, a second groove body and a pulley; two first fixed blocks are movably provided on the outer wall of the double-thread screw; screw grooves and limiting holes are penetrated at the left and right ends of the first fixed block; the inner wall of the screw groove is adapted to the outer wall of the double-thread screw; the second fixed block is fixedly connected to the rear end of the first fixed block; the outer wall of the second fixed block fits with the inner wall of the limiting groove; two second groove bodies are provided at the lower end of the first fixed block; pulleys are rotatably installed on the inner walls of the front and rear ends of the second groove body; the outer wall of the limiting column fits with the inner wall of the limiting hole, and when the double-thread screw rotates, the first fixed block is restricted by the second fixed block in the limiting groove, so that the two first fixed blocks move toward one end away from each other until the distance between the two first fixed blocks is the same as the width of the portable building board, and then the rotation stops.

[0011] Preferably, the diameter of the pulley is two centimeters larger than the distance from the upper end of the inner wall of the second trough body to the lower end of the outer wall of the pulley. When the two first fixed blocks move toward one end away from each other, the pulley on the inner wall of the second trough body rotates with the movement of the first fixed block, thereby reducing the friction between the lower end of the first fixed block and the ground, so that the first fixed block can move smoothly.

[0012] Beneficial effects of the utility model:

[0013] 1. When the double-thread screw is rotated, the first fixing block is restricted by the second fixing block in the limiting groove and the limiting column in the limiting hole, so that the two first fixing blocks move toward one end away from each other until the distance between the two first fixing blocks is the same as the width of the portable building board and the rotation stops, thereby facilitating the positioning of the portable building board and solving the problem of inconvenient positioning of the portable building board;

[0014] 2. When the portable building board is located at the front end of the housing, the reflector is pulled out from the first slot and placed under the building board. The content reflected by the reflector is used to solve the problem that it is inconvenient to observe the insertion status between the positioning steel bar and the reserved steel bar hole on the building board, so that the installation and positioning process consumes a lot of time;

[0015] 3. When the portable building board moves downward, the contact with the outer wall of the roller can make the portable building board descend more stably and make the portable building board close to the outer wall of the roller, thereby reducing the operation of correcting the portable building board.

[0025] See also Figure 4 In the present embodiment, the positioning assembly 5 comprises a first fixing block 501, a second fixing block 502, a limiting hole 503, a screw groove 504, a second slot body 505 and a pulley 506; two first fixing blocks 501 are movably arranged on the outer wall of the double-thread screw 401; screw grooves 504 and limiting holes 503 are provided through the left and right ends of the first fixing block 501; the inner wall of the screw groove 504 is adapted to the outer wall of the double-thread screw 401; the rear end of the first fixing block 501 is fixedly connected with the second fixing block 502; the outer wall of the second fixing block 502 is fitted with the inner wall of the limiting slot 106; two second slot bodies 505 are provided at the lower end of the first fixing block 501; the pulley 506 is rotatably installed on the inner walls of the front and rear ends of the second slot body 505; the outer wall of the limiting column 105 is fitted with the inner wall of the limiting hole 503, and the diameter of the pulley 506 is two centimeters longer than the distance from the upper end of the inner wall of the second slot body 505 to the lower end of the outer wall of the pulley 506.

[0026] When positioning and clamping is required, the first gear 302 on the outer wall of the rotating rod 301 can be rotated by rotating the rotating rod 301 on the inner wall of the first through hole 102.

When the portable building panel moves downward, the contact with the outer wall of the roller 202 can make the portable building panel descend more stably.

[0029] Through the above steps, the device is installed on the ground at the connection of the portable building board. By rotating the first rotating component 3, the second rotating component 4 is driven to rotate, thereby adjusting the distance between the two positioning components 5, and positioning restrictions are made. Then, the reflector on the limiting component 1 is pulled out. When the portable building board needs to be installed, the rolling component 2 is used to contact the building board. By observing the limiting component 1, the positioning component 5 limits the portable building board, thereby solving the problem of repeated adjustments during the installation of the portable building board, which is time-consuming and labor-intensive.
