Description

Technical Field

[0001] This utility model relates to the field of automatic walkway technology, and in particular to an adaptive adjustable intermediate support device for an automatic walkway. Background Technology

[0002] Moving walkways are widely used in various public places, such as large supermarkets. The inclination angle of moving walkways is typically between 10° and 12°, exhibiting randomness. These irregular and subtle angle variations pose challenges to the structural design and installation adjustment of the intermediate support structure. While various types of intermediate support structures exist in the industry, they still have some drawbacks:

[0003] Patent document CN210944478U provides an adjustable escalator mid-section support device, which is designed with an escalator angle adjustment mechanism, a height adjustment mechanism, and a width adjustment mechanism. Its advantage is that the height and angle are adjustable; its disadvantage is that all adjustment work depends on manual operation, and the entire support is designed as a whole, with a large and complex structure; in engineering sites, space is very limited, making it very difficult to achieve manual adjustment of its three dimensions.

[0004] Patent document CN214935206U provides a height-adjustable intermediate support device for escalators, which uses a support base with a slope and a support pad to achieve height adjustment; its disadvantage is that the tilt angle of the support cannot be adjusted. Utility Model Content

This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0006] To solve the above-mentioned technical problems, this utility model provides an angle-adaptive adjustable intermediate support device for an automatic walkway, comprising: an upper support seat, which is fixedly connected to the truss of the automatic walkway, and a lower support seat, which supports the upper support seat; the upper support seat has an outwardly convex cylindrical surface, and the lower support seat has an inwardly concave cylindrical surface, wherein the cylindrical surfaces of the upper support seat and the lower support seat are adapted to each other.

[0007] Preferably, the upper support base is fixedly connected to the truss of the moving walkway by bolts, and the lower support base is abutted against the civil engineering pad by support bolts.

[0008] Preferably, the width of the upper support seat in the axial direction is smaller than that of the lower support seat.

[0010] Preferably, the cylindrical surfaces of the upper support and the lower support are joined together, and the center line of the cylinder is perpendicular to the inclination angle of the moving walkway, so that the rotation of the cylindrical surface can adapt to the inclination angle of the moving walkway.

[0011] Preferably, the civil engineering pad includes a steel pad and a shock-absorbing pad, with the shock-absorbing pad in contact with the civil engineering structure.

[0012] Preferably, the lower support seat is abutted against the steel pad by a support bolt, and the height of the support is adjusted by the support bolt.
