Description

Technical Field

[0001] This utility model relates to a prefabricated building trolley, belonging to the technical field of prefabricated building trolleys. Background Technology

[0002] Prefabricated building trolleys are specialized mobile devices used for the transportation, positioning, installation, and auxiliary operations of components in prefabricated building construction. Their core function is to solve the problem of efficient transfer and precise assembly of prefabricated components (such as wall panels, composite slabs, stairs, beams, columns, etc.) at the construction site. They are one of the key pieces of equipment for improving the efficiency, safety, and precision of prefabricated building construction.

[0003] Chinese Patent (Publication No.: CN 220909709 U) discloses a prefabricated detachable construction trolley, including four sets of transverse connecting rods, with multiple sets of longitudinal connecting rods connected between the four sets of transverse connecting rods. A quick-fixing structure is connected at the connection points of the transverse and longitudinal connecting rods. The quick-fixing structure includes a fixed connecting plate, with fixed connecting columns symmetrically connected to the side wall of the fixed connecting plate. Multiple sets of conical hook teeth are provided on the side wall of the other end of the fixed connecting column. This invention, by incorporating a quick-fixing structure in the prefabricated detachable construction trolley, utilizes the conical hook teeth and connecting hook teeth in the quick-fixing structure, along with the connecting structure, to quickly fix the transverse and longitudinal connecting rods. This design facilitates the assembly and disassembly of devices during the use of the prefabricated detachable construction trolley, making transportation very convenient and solving the problem of inconvenient assembly and disassembly. In prefabricated building construction, the transfer and installation of prefabricated components (such as wall panels, floor slabs, beams and columns) is a core link. Existing prefabricated building trolleys mostly adopt a horizontal load-bearing structure. When loading, external hoisting equipment is needed to accurately place the components on the trolley's load-bearing surface. When unloading, manual or auxiliary equipment is also needed to adjust the angle of the components to match the installation position. This is not only cumbersome and inefficient in loading and unloading, but also prone to damage to the edges and corners due to the hard contact between the components and the trolley's load-bearing surface. At the same time, the component fixing methods of existing trolleys are mostly single-sided clamping or simple binding, with uneven fixing force. During the transfer process, the components are prone to shifting or tilting, resulting in poor fixing stability and safety hazards. Therefore, there is an urgent need for a prefabricated building trolley that combines tilt adjustment function with a stable fixing structure to solve the pain points of existing equipment.

[0004] To address this, a prefabricated building trolley is proposed. Summary of the Invention

[0023] By setting the tilting mechanism 200, the placement platform 103 can be tilted, making it easier for precast components to slide along the tilted surface into the top of the placement platform 103 during loading, reducing the precision positioning requirements of the hoisting equipment; during unloading, the tilt of the placement platform 103 can be adjusted according to the angle of the installation position, and the components can be directly sent to the installation position without additional adjustment of the component angle, which greatly improves the loading and unloading efficiency and reduces the intensity of manual labor. Example 2

[0024] like Figure 4 and Figure 5 As shown, in one embodiment, a fixing mechanism 300 is also included. The fixing mechanism 300 includes an L-shaped plate 301, which is fixedly connected to the right side of the top of the placement platform 103. A cylinder 302 is fixedly connected to the inner side of the L-shaped plate 301. A moving block 303 is fixedly connected to the telescopic end of the cylinder 302. The front and rear sides of the top and bottom of the moving block 303 are movably connected to second swing rods 304 through pivots.

[0026] like Figure 3-6 As shown, in one embodiment, anti-slip pads 309 are glued to the inner sides of both the second fixing plate 308 and the first fixing plate 306 with PP adhesive. The anti-slip pads 309 are made of rubber. A sliding groove 310 is provided on the left side of the top of the placement platform 103. Sliding blocks 311 are fixedly connected to the bottom of the second fixing plate 308, and the sliding groove 310 is slidably connected to the inner side of the sliding block 311. Connecting plates 312 are fixedly connected to the front and rear sides of the right side of the placement platform 103. A sliding rod 313 is fixedly connected to the inner side, and a sliding sleeve 305 is slidably connected to the inner side of the connecting plate 312.

By setting the sliding groove 208 and the slider 209, the movement of the threaded sleeve 204 can be limited.

[0028] When this utility model is in operation: First, when it is necessary to feed the pre-component, the servo motor 202 on the left rotates, driving the threaded rod 203 to rotate. The threaded rod 203 drives the threaded sleeve 204 to move to the left. The threaded sleeve 204 drives the first swing rod 205 to swing, thereby causing the fixed block 206 and the placement platform 103 to tilt. At this time, it is convenient to place the pre-component on the top of the placement platform 103. After placement, the telescopic end of the cylinder 302 extends to the left, driving the moving block 303 to move, thereby driving the second swing rod 304 to swing. The second swing rod 304 drives the second fixed plate 308 to move synchronously through the connecting rod 307 to fix the pre-component. The anti-slip pad 309 prevents the pre-component from sliding. After moving to the preset position through the moving wheel 102, the servo motor 202 on the left is started again, so that the placement platform 103 tilts to facilitate unloading. The tilting mechanism 200 on the right can cooperate with the tilting mechanism 200 on the left to adjust the height of the placement platform 103.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
