Description

[Technical Field]

[0001] This invention relates to a roller coaster frame structure. [Background Technology]

[0002] Existing roller coasters generally consist of a frame, with a pulley assembly at the bottom and a shell on top. The frame further includes a base and a seat frame fixed to it. The seat frame has a seat cushion and a backrest.

[0003] Existing roller coaster frames are generally welded from multiple pieces of iron. This welding process is extensive, labor-intensive, and makes it difficult to guarantee weld quality. Problems such as blistering, slag inclusions, undercut, weld beads, burn-through, incomplete penetration, lack of fusion, dents, collapses, incomplete filling, and cracks are common. If the two pieces of iron being welded have different compositions, thermal expansion and contraction can cause the weld to crack or even break. To accommodate multiple seat frames on the base, existing roller coasters typically design the base as a frame structure, with seat frames fixed to the left and right sides. This results in a large base, high manufacturing costs, and inconvenient installation. The existing base and seat frame fixing structure has the following drawbacks: 1. Inefficient design, inconvenient installation; 2. Insecure fixing, leading to seat frame wobbling after prolonged use. [Summary of the Invention]

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a roller coaster frame structure that reduces worker labor intensity, improves processing quality, has a long service life, requires no subsequent maintenance, has a more stable and stronger structure, low manufacturing cost, is easy to install, and allows for convenient connection between the seat frame and the main beam, resulting in a robust structure.
