Description

Technical Field

[0001] This invention relates to the field of workshop material transportation technology, and in particular to a workshop telescopic conveyor based on a monorail. Background Technology

[0002] Currently, monorail transportation has become increasingly common in workshop material handling due to its advantages such as simple transportation process, high efficiency, energy saving, and environmental friendliness. However, monorails can only move materials vertically and longitudinally, and materials transported by monorails can only be placed directly under the monorail beam, affecting loading and unloading operations and causing numerous inconveniences to production and safety. In the past, workers used crowbars or hand-operated hoists to push materials, which were not only inefficient but also labor-intensive, unsafe, and seriously threatened the personal safety of workers.

[0003] Currently, in practical applications of monorail cranes, the disadvantages of traditional monorail cranes are: (1) Most traditional monorail crane locomotives run in straight lines, which increases the labor intensity of workers and reduces work efficiency; (2) Traditional monorail crane locomotives are noisy; (3) The running track of traditional monorail crane locomotives is fixed by suspension, which makes the locomotive body prone to swaying during operation, restricting the transportation of heavy equipment and posing a great safety hazard; (4) Most traditional monorail crane locomotives are driven by diesel engines, and the exhaust gas emitted during operation has a small amount of pollution and odor, so it is necessary to strengthen the ventilation of the working environment.

[0004] CN205971291U discloses an electro-hydraulic monorail crane and CN113233325A discloses a mining monorail crane, proposing a monorail crane powered by electric energy, which can effectively solve the problems of noise and environmental pollution. However, the above patents do not solve the problems of traditional monorail cranes, most of which run on straight tracks and sway during operation, which are inconvenient for workers and reduce work efficiency.

[0005] Therefore, this invention proposes a workshop telescopic conveying device based on a monorail. Addressing the issue that monorails can only move materials vertically and longitudinally during transport, this invention designs a workshop telescopic conveying device based on a monorail that can flexibly turn. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention proposes a workshop telescopic conveyor based on a monorail crane, which solves the problem of machine body swaying, allows for flexible turning, and improves work efficiency.

The monorail track includes a straight section, a curved section, and a connection between the straight section and the curved section. The straight section is made of H-beam. The curved section is composed of two identical upper and lower curved sections. The lower curved section and the H-beam are connected by a narrow connecting plate and a bolt group. The upper curved section and the H-beam are connected by a wide connecting plate and a bolt group. The upper and lower curved sections are connected by a long bolt group. The monorail track is connected to an anti-seismic bracket through holes on the upper surface of the H-beam, and is connected to the workshop ceiling through the anti-seismic bracket.

[0008] The traveling trolley includes a driving unit and a driven unit. The driving unit includes a U-shaped support plate, a support wheel assembly, a drive wheel assembly, a traveling servo motor transmission assembly, a guide wheel assembly, and a suspension assembly. One support wheel assembly is bolted to each side of the U-shaped support plate. The drive unit is supported on the H-beam by the contact between the wheel surface of the support wheel assembly and the surface of the H-beam. The drive wheel assembly is installed at the lower part of the support wheel assembly and bolted to the U-shaped support plate. The traveling servo motor transmission assembly provides rotational power to the drive wheel assembly, enabling it to move on the monorail. The guide wheel assemblies are bolted to the U-shaped support plate and are located on both sides of the support wheel assembly.

[0009] The bottom flange block of the suspension assembly is bolted to the bottom upper surface of the U-shaped support plate, and the suspension assembly is connected to the upper connecting plate of the telescopic load-bearing device.

[0012] The drive guide rail mechanism includes an upper guide rail assembly, a lower guide rail assembly, an intermediate connecting assembly, and a drive assembly. The upper end of the upper guide rail assembly is connected to the upper connecting plate, and the lower end of the lower guide rail assembly is connected to the lower connecting plate.
