AI Technical Summary

Technical Problem

In offshore ships, high-altitude equipment needs to be operated or repaired, but the space is narrow and it is impossible to provide a permanent platform. The platform will occupy the passage, resulting in the inability to effectively solve the operation and maintenance problems of high-altitude equipment.

Method used

A folding invisible step is designed, including a fixed frame, a rotary step frame, a steel plate mesh, and a detachable leg. It is fixed by pin connection and limit plate, so it can be easily extended without occupying the passage space. and fold, providing a temporary operating platform.

Benefits of technology

It realizes that high-altitude equipment can be operated or maintained safely and conveniently in an environment with limited space, occupying small space and not occupying channel space, and has strong practicality and operating performance.

Description

Technical Field

[0001] The invention relates to a foldable invisible step. Background Art

[0002] At present, all types of ships at sea have equipment parts or valves that need to be operated or repaired at high places, and areas that need to be reached by the crew with both hands. Usually, a straight ladder or a permanent operating platform is directly provided, or a herringbone ladder is moved for operation when necessary. However, there may be narrow spaces where a permanent platform cannot be provided or providing a platform will occupy the passage, such as various machine rooms with limited space, well enclosures, etc. Therefore, a foldable invisible step that does not occupy the passage space at ordinary times and is convenient, safe and practical to use is needed. Summary of the invention

[0003] The purpose of the present invention is to provide a foldable invisible step which does not occupy passage space and is convenient, safe and practical to use.

[0004] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: a foldable invisible step, comprising a fixed frame (1), a fixed frame pad (3), a fixed frame sleeve (4), a rotating step frame (6), a steel plate mesh (7), a rotating step frame sleeve (8), a pin (11) and a detachable leg (12), wherein the fixed frame pad (3) is fixed to the fixed frame (1), the fixed frame sleeve (4) is mounted on the fixed frame pad (3), the rotating step frame (6) is connected to the fixed frame (1) via the pin (11), the steel plate mesh (7) is mounted on the rotating step frame (6), the rotating step frame sleeve (8) is fixed below the rotating step frame (6), and the detachable leg (12) is connected to the rotating step frame sleeve (8).

[0005] A fixed frame limiting plate (2) and a butterfly nut fixing structure (5) are installed on the fixed frame (1).

[0006] A first rotating step frame limiting plate (9) is installed below the rotating step frame (6).

[0007] A second rotating step frame limiting plate (10) is installed on the top of the rotating step frame (6).

[0008] A leg pad (13) is installed at the bottom of the detachable leg (12).

[0009] The present invention discloses a foldable invisible step, which is mainly used for operating or maintaining various equipment located at a height of about 2 meters to 2.5 meters, occupies a small space, does not occupy passage space, is convenient and safe to use, and has strong practicality and operability. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 The utility model is a structural schematic diagram of a foldable invisible step of the present invention.

[0011] In the figure: 1. fixed frame; 2. fixed frame limit plate; 3. fixed frame pad; 4. fixed frame sleeve; 5. butterfly nut fixing structure; 6. rotating step frame; 7. steel plate mesh; 8. rotating step frame sleeve; 9. first rotating step frame limit plate; 10. second rotating step frame limit plate; 11. pin shaft; 12. detachable support leg; 13. support leg pad. DETAILED DESCRIPTION
