Description

Technical Field

[0001] This utility model relates to a working platform for a methanol storage chamber. Background Technology

[0002] With increasing environmental awareness, various low-carbon or zero-carbon fuels such as methanol, ammonia, hydrogen, and biofuels are favored by the shipping industry as alternative energy sources to reduce carbon emissions from ships. Methanol fuel is rapidly developing into the most feasible, least emitting, and lowest-cost alternative for marine fuels. Methanol can reduce the emission of most harmful gases, achieving zero carbon emissions for ships. Ammonia fuel is composed only of nitrogen and hydrogen atoms and does not produce harmful gases containing carbon or sulfur when burned as marine fuel, making it a preferred choice for marine fuels as well. However, due to the large volume of methanol fuel tanks, workers need to erect large scaffolding to facilitate pipeline installation inside the tanks, and dismantle it after installation, which greatly affects work efficiency and poses safety hazards.

[0014] like Figure 1-2 As shown, the present invention discloses a working platform for a methanol storage compartment, comprising a methanol storage compartment 9 located below a deck 8. A hatch 91 is located at the center of the top of the methanol storage compartment 9. A lifting platform 3 is installed at the hatch 91 in a lifting manner. A hydraulic cylinder 4 is connected to the upper part of the lifting platform 3. A rotating shaft 2 is vertically installed at the lower part of the lifting platform 3 and is driven to rotate by a motor 23. The upper part of the rotating shaft 2 is rotatably connected to the lifting platform 3 via a bearing seat 21. The middle part of the rotating shaft 2 is connected to the motor 23 via a gear transmission mechanism 22. The motor 23 is installed at the bottom of the lifting platform 3. The lower end of the rotating shaft 2 has a diameter... The operating platform 1 is slidably mounted on the guide plate 13 via the guide rail 12. The side of the operating platform 1 facing the rotating shaft 2 is connected to the side push hydraulic cylinder 14. The top push hydraulic cylinder 4 is mounted on the upper fixed plate 7. The upper fixed plate 7 is located above the deck 8 via the support seat 6. The upper part of the support seat 6 is fixed to the upper fixed plate 7, and the lower part of the support seat 6 is placed on the deck 8. A guide rod 5 is provided between the upper fixed plate 7 and the lifting platform 3. The lower end of the guide rod 5 is fixed to the lifting platform 3, and the upper part of the guide rod 5 forms a sliding fit with the upper fixed plate 7.

It is mainly supported by a support base, and the position of the lifting platform corresponds to the hatch position of the methanol storage tank. During operation, the operator enters the operating platform and uses the push hydraulic cylinder to control the overall descent of the lifting platform. The operating platform enters the methanol storage tank through the hatch until it reaches the designated height. Then, the radial position of the operating platform can be adjusted by the side push hydraulic cylinder. The motor can drive the rotating shaft and the operating platform to rotate synchronously through the gear transmission mechanism, thereby realizing the all-round position adjustment of the operating platform.
