Description

Technical Field

[0001] The present invention relates to the field of construction, and more specifically, to a prefabricated building construction platform. Background Art

[0002] A prefabricated building refers to a building in which a large amount of on-site work in the traditional construction method is transferred to a factory. Building components and fittings, such as floor slabs, wall panels, stairs, balconies, etc., are processed and manufactured in the factory, transported to the construction site of the building, and assembled and installed on-site through reliable connection methods. Prefabricated buildings mainly include precast prefabricated concrete structures, steel structures, modern wood structure buildings, etc. Because of their standardized design, factory production, assembly construction, information management, and intelligent application, they are representatives of modern industrial production methods. During the construction process of prefabricated buildings, a unloading platform is required to transport and turnover objects.

[0003] Existing unloading platforms are mainly composed of cantilever beams, turnover boxes, fixing parts, etc. The cantilever beams are fixed to the building through fixing parts, and the turnover boxes are fixedly installed on the cantilever beams. During use, the tower crane hoists the objects into the turnover boxes, and then workers manually take the objects out of the turnover boxes and transfer them to the stacking area. However, workers need to enter the turnover boxes to pick up the objects. The turnover boxes are cantilevered in the air, and the operation process is relatively dangerous. Moreover, the speed of manually transferring objects is slow, which requires long-term occupation of the unloading platform, and the turnover efficiency of objects is low. Therefore, there is an urgent need to design a prefabricated building construction platform. Summary of the Invention

Through the positioning and clamping parts, the main body of the construction platform can be fixed in the working position, preventing the main body of the construction platform from moving during the process of receiving objects, ensuring that the objects can accurately fall into the main body of the construction platform, avoiding the risk of objects falling, and helping to further increase safety.

[0041] Working principle:

[0042] First, an upward lifting force is applied to the linkage force ring 411, and then the linkage force ring 411 moves the linkage extension rod 410 upward, and then the linkage extension rod 410 moves the linkage piston plate 409 upward, and then the linkage piston plate 409 moves upward with the engaging positioning strip 412, and then the engaging positioning strip 412 is pulled out of the engaging groove 403, and then a pulling force is applied to the construction platform body 2 through the operating handle 24, and then the construction platform body 2 moves to the right with the objects inside it, and then the protective enclosure 23 moves to the right with the engaging positioning strip 412 through the positioning engaging block 404, and then the engaging positioning strip 412 is staggered with the positioning base 401, and then the linkage force ring 411 is released, and then the engaging transmission column 408 is engaged with the elastic member Under the action of the elastic force of 407, the linkage piston plate 409 moves downward, and then the linkage piston plate 409 moves downward with the engaging positioning strip 412, and then the linkage piston plate 409 moves downward to the extreme position inside the positioning engaging cavity 405, and then the construction platform body 2 is pushed to the object stacking position through the operating handle 24, and then the unloading instruction is sent to the control module 603 through the control panel 25, and then the control module 603 controls the locking motor 604 to run, and then the locking motor 604 rotates the locking rotating rod 605, and then the locking rotating rod 605 rotates with the locking threaded rod 610 through the plug-in effect between the anti-rotation angle column 613 and the anti-rotation angle cavity 611, and then the locking threaded rod 610 is relatively connected to the splicing reinforcement block 53 The locking threaded rod 610 is rotated, and then the locking threaded rod 610 moves to the right relative to the splicing reinforcement block 53 under the action of the threaded cooperation between it and the central threaded hole 56, and then the splicing reinforcement block 53 is slowly pulled out from the inside of the locking opening column groove 606 under the action of the elastic force of the pre-tensioning spring 52, and then the locking threaded rod 610 is completely moved out of the central threaded hole 56, and then the splicing reinforcement block 53 is pressed against the position limiting member 57 under the action of the elastic force of the pre-tensioning spring 52. At this time, the right end face of the central threaded hole 56 is flush with the right end face of the load-bearing front bottom plate 21. At the same time, the directional guide slide plate 609 moves to the right with the locking threaded rod 610 under the action of the elastic force of the reset traction spring 608, so that the locking threaded rod 610 is retracted into the inside of the locking opening column groove 606. Until the directional guide slide plate 609 is pressed on the end of the electromagnetic telescopic rod 607, the load-bearing front bottom plate 21 and the load-bearing rear bottom plate 22 are separated, the control module 603 controls the locking motor 604 to stop, and then applies a pulling force to the load-bearing front bottom plate 21 through the operating handle 24 and the protective enclosure 23, and then the load-bearing front bottom plate 21 gradually moves away from the load-bearing rear bottom plate 22, and then the thrust exerted on the power flap 709 disappears, and then the loading plate 712 flips downward under the action of the gravity of the objects thereon and applies pressure to the load-bearing long roller 705, and then the load-bearing long roller 705 turns downward with the flip long piece 704 and the flip short piece 703 as the center axis, and then the flip long piece 704 moves downward with the linkage bar 707 through the linkage column pin 706,Until the linkage cross bar 707 contacts the top surfaces of the front load-bearing bottom plate 21 and the rear load-bearing bottom plate 22, at this time, the position height of the load-bearing long roller 705 is the lowest, and the free end of the load-carrying plate member 712 is in a downward inclined state. Then, the objects on the load-carrying plate member 712 slide downward along the top surfaces of the load-carrying plate member 712 and the engaging comb teeth 713. After that, the objects slip off from the ends of the engaging comb teeth 713 and fall to the ground. Then, the front load-bearing bottom plate 21 and the rear load-bearing bottom plate 22 are pulled to the vacant area and aligned, and at this time, the power flap 709 on the front load-bearing bottom plate 21 abuts against the left side surface of the rear load-bearing bottom plate 22, and the power flap 709 on the rear load-bearing bottom plate 22 abuts against the right side surface of the front load-bearing bottom plate 21. Then, a fitting instruction is sent to the control module 603 through the control panel 25. After that, the control module 603 controls the electromagnetic telescopic rod 607 to extend. Then, the electromagnetic telescopic rod 607 pushes the directional guiding slide plate 609 to move leftward. Then, the directional guiding slide plate 609 pulls the reset traction spring 608. After that, the reset traction spring 608 is elastically stretched, and the elastic potential energy increases. Then, the directional guiding slide plate 609 moves the locking threaded rod 610 out leftward. Then, the end of the locking threaded rod 610 is inserted into the internal center threaded hole 56. After that, the control module 603 controls the locking motor 604 to operate. Then, the locking motor 604 drives the locking rod 605 to rotate. Then, the locking rod 605 drives the locking threaded rod 610 to rotate through the plugging action between the anti-rotation angular prism 613 and the anti-rotation angular cavity 611. After that, the locking threaded rod 610 moves into the internal center threaded hole 56 under the action of its threaded fit with the center threaded hole 56. At the same time, the center threaded hole 56 exerts a leftward pulling force on the locking threaded rod 610 through the threaded fit between it and the locking threaded rod 610. Then, the locking threaded rod 610 moves leftward. Then, the anti-rotation angular prism 613 moves to the extreme right end inside the anti-rotation angular cavity 611. After that, the locking rod 605 drives the splicing reinforcement block 53 to move rightward through the plugging action between the anti-rotation angular prism 613 and the anti-rotation angular cavity 611 and the threaded fit between the locking threaded rod 610 and the center threaded hole 56. Then, the splicing reinforcement block 53 moves out from the internal splicing reinforcement opening groove 51 and pulls the pre-stretched spring 52. The pre-stretched spring 52 is elastically stretched, and the elastic potential energy increases. After that, the end of the splicing reinforcement block 53 is inserted into the internal locking opening column groove 606. Then, the splicing limiting slide 55 slides leftward to the extreme position inside the splicing limiting groove 54. Then, the splicing reinforcement block 53 exerts a rightward pulling force on the splicing limiting slide 55 through the inner wall of the splicing limiting groove 54. After that, the splicing limiting slide 55 drives the front load-bearing bottom plate 21 to approach the rear load-bearing bottom plate 22. Then, the front load-bearing bottom plate 21 and the rear load-bearing bottom plate 22 exert a squeezing force on the power flap 709. Then, the power flap 709 drives the flipping long piece 704 to flip in the reverse direction. After that, the flipping long piece 704 drives the load-bearing long roller 705 to flip in the reverse direction.Then, the load-bearing long roller 705 applies an upward jacking force to the load-carrying plate member 712. Subsequently, the inclination of the load-carrying plate member 712 gradually decreases. After that, the front load-bearing bottom plate 21 and the rear load-bearing bottom plate 22 are butted together, and the two protective enclosing plates 23 are butted together. At this time, the load-carrying plate member 712 is in a horizontal state. Then, the construction platform main body 2 is pushed closer to the cantilever beam 11. Subsequently, the assembly pulley 30 comes into contact with the surface of the climbing inclined plane 36. After that, the climbing inclined plane 36 applies an upward lifting force to the assembly pulley 30. Then, under the action of this lifting force, the assembly pulley 30 drives the construction platform main body 2 to move upward. Subsequently, the transfer wheel body 26 moves upward and separates from the ground. After that, the assembly pulley 30 rolls onto the top surface of the cantilever beam 11. Then, the assembly pulley 30 enters the interior of the U-shaped anti-detachment strip 38 and the depth opening hole 39. Subsequently, the construction platform main body 2 moves synchronously with the positioning engaging block 404. After that, the chamfered inclined plane 413 comes into contact with the guiding inclined plane 402. Then, the guiding inclined plane 402 applies an upward thrust to the engaging positioning strip 412 through the chamfered inclined plane 413. Subsequently, the engaging positioning strip 412 moves upward. After that, the engaging positioning strip 412 slides onto the top surface of the positioning base 401. Then, the engaging positioning strip 412 is aligned with the engaging groove 403. Subsequently, under the action of the elastic force of the engaging elastic member 407, the engaging transmission column 408 drives the engaging positioning strip 412 to insert into the engaging groove 403 through the linkage piston plate 409. Thus, the construction platform main body 2 is fixed in the working position. After that, hoist objects into the construction platform main body 2, and that's it.,
