Description

Technical Field

[0001] This utility model relates to the field of transportation technology in building installation engineering, specifically to an auxiliary transportation device for prefabricated cages. Background Technology

[0002] Currently, the transportation of prefabricated pipelines in building installation projects, and the auxiliary transportation devices used in the transportation and transfer of prefabricated cages generally suffer from technical bottlenecks such as poor convenience, low time efficiency, and high cost. Traditional devices often use temporary means such as logs, slide rails, or forklifts, resulting in low disassembly and assembly efficiency, redundant volume, and a great contradiction with the fast and convenient prefabricated installation mode, which significantly reduces the efficiency of prefabricated pipeline implementation in installation projects and increases construction costs.

[0003] In existing technologies, although prefabricated pipes and assembled cages attempt lightweight designs, the lack of topology optimization results in weak local structures, still requiring external reinforcement frames, further exacerbating portability issues. Furthermore, the non-intelligent coupling design of transport units and functional components necessitates on-site assembly with specialized tools and technicians, leading to a waste of both time and money, severely restricting application flexibility, hindering adaptive adjustment under complex working conditions, and causing inconvenience in on-site transportation. Moreover, the large size of the assembled cages is also a disadvantage for transport. Therefore, further improvements are needed. Utility Model Content

[0004] To solve the above problems, this utility model provides the following technical solution. An auxiliary transportation device for a prefabricated cage includes a U-shaped iron block. Fastening bolts are screwed onto two sides of the U-shaped iron block. An iron plate is fixedly installed on the top of the U-shaped iron block via the fastening bolts. Annular stress diffusion grooves are provided on the top sides of the two sides of the fastening bolts, and double-layer disc springs are fixedly installed within the grooves. Mounting seats are fixedly installed on both sides of the bottom of the iron plate. A threaded cylinder is fixedly installed in the middle of the bottom side of the U-shaped iron block. A buffer bearing module is provided inside the U-shaped iron block. Lifting and leveling modules are installed on the bottom sides of both ends of the iron plate via mounting seats. An adaptive walking module is installed on the bottom of the U-shaped iron block via the threaded cylinder.

[0005] As an optimization, the buffer support module is a base plate installed inside the U-shaped iron block. The base plate has a base layer, a reinforcing layer and a contact layer. The reinforcing layer is a wedge-shaped rib, the contact layer is vulcanized nitrile rubber, and a trapezoidal anti-slip groove is provided on its surface.

[0006] As an optimization, the lifting and leveling module is a hydraulic jack, and the top of the hydraulic jack is mounted on the bottom of the mounting bases on both sides. By working the hydraulic jacks on both sides, the prefabricated box can be lifted to a high position, and then the adaptive walking module can be easily installed or disassembled.

[0007] As an optimization, the adaptive walking module includes a Buddha head wheel assembly, on the top of which a screw is fixedly mounted, and the screw is screwed into the inside of a threaded cylinder.

[0008] As an optimization, the Buddha head wheel assembly consists of an annular iron ring, a semi-circular spherical cap, a large cast steel ball, and small cast steel balls. The semi-circular spherical cap is located above the annular iron ring and hinged to it. The large cast steel ball is rotatably embedded inside the annular iron ring. Several small cast steel balls are embedded inside the annular iron ring and the semi-circular spherical cap, and the small cast steel balls are arranged around the large cast steel ball.

[0009] As an optimization, a fixing cylinder is fixedly installed on one side of the free end of the cast steel ball, and a screw is screwed into the inside of the fixing cylinder. The semi-circular ball cover is fixedly installed and positioned on the top side of the annular iron ring by screwing the cast steel ball.

[0010] As an optimization, a brake component is provided at the center of the side of the annular iron ring. The brake component includes a brake lever fixedly installed at the center of the top side of the annular iron ring. The telescopic end of the brake lever is fixedly installed with a brake pad for contacting a cast steel ball and braking by friction. The brake pad is made of sintered metal material.

[0011] As an optimization, a cleaning component for cleaning the surface of the cast steel ball is provided on the bottom side of the annular iron ring. The cleaning component includes a spring steel hook fixedly installed on the bottom side of the annular iron ring. A nylon spiral brush head for contacting the cast steel ball and cleaning its surface is installed inside the spring steel hook.

[0012] The beneficial effects of this utility model are as follows: This prefabricated auxiliary transportation device, by constructing a coupled transmission system and a lightweight topology architecture, simultaneously solves the problems of limited autonomous operation capabilities caused by low operational levels during autonomous loading and unloading, the risk of dirt and jamming of the walking mechanism in complex terrain, and the structural instability caused by insufficient reliability of frame node connections. Ultimately, it achieves a systematic improvement in transportation efficiency, environmental adaptability, and life-cycle economics. This prefabricated auxiliary transportation device can lift the prefabricated box to a high position by working the hydraulic jacks on both sides, and then easily install or disassemble the adaptive walking module. The rolling of the cast steel ball facilitates the transportation of the prefabricated box. By activating the brake lever, the brake pads will contact the cast steel ball, thereby achieving the braking effect. The nylon spiral brush head can clean the surface of the cast steel ball, avoiding the impact of impurities on the surface of the cast steel ball on transportation. Attached Figure Description

A trapezoidal anti-slip groove with a bottom width of 3mm, a top width of 5mm, a groove depth of 2.5mm, a spacing of 10mm, and a tolerance of ±0.1mm is added to its surface, with a friction coefficient ≥0.85. The interface between the rubber layer and the steel plate is chemically etched.

[0024] See Figure 3 The lifting and leveling module is a hydraulic jack 7, and the top of the hydraulic jack 7 is mounted on the bottom of the mounting bases 4 on both sides. By working the hydraulic jacks 7 on both sides, the prefabricated box can be lifted to a high place, and then the adaptive walking module can be easily installed or disassembled.
