Description

Technical Field

[0001] This invention relates to a step device for adjusting the hatch cover of a container ship, which belongs to the technical field of step platforms for standing personnel working at heights. Background Technology

[0002] The assembly and welding of the adjustment plate for the container ship hatch cover on the lashing bridge rails is carried out in a confined space. The workers' posture is to place one foot on the hatch coaming plane and the other foot on the end of the cargo hold rail, with the safety belt attached to the lashing bridge. The disadvantages of this posture are that it is extremely difficult from a safety point of view. Because the sole of the foot is on the structure and the contact area between the sole and the structure is small, the worker's feet and legs are prone to fatigue, making it impossible to work for a long time. At the same time, the worker's feet cannot move freely during the operation, and blindly moving poses a risk of falling. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides a working step device for adjusting the container ship hatch cover. Combining the structural characteristics of the working position and the inherent structure of the cargo hold guide rail, personnel can stand on the step platform to perform operations, improving the working posture, allowing personnel to move freely, and reducing the risk of falling.

[0004] The technical solution adopted in this invention is: a container ship hatch cover adjustment plate operation step device, wherein the container cargo hold facade is connected to the guide rail base through the guide rail base connecting block, the guide rail base is provided with the cargo hold guide rail, and the upper platform of the device is connected to the lower platform through the support, forming a stepped shape; A first stop plate and a second stop plate are provided behind the upper platform support beam. The end face of the guide rail base is located between the upper platform support beam and the first stop plate and the second stop plate. The first fastening bolt and the second fastening bolt pass through the upper platform support beam and act on the end face of the guide rail base, cooperating with the first stop plate and the second stop plate. The lower platform is provided with a lower platform support beam at its bottom, and a wedge-shaped base is provided below the lower platform support beam. The first wedge block of the wedge base interacts with the first inclined surface of the guide rail at the end of the cargo hold guide rail, and the second wedge block interacts with the second inclined surface of the guide rail. The top plane of the guide rail acts on the lower platform support beam.

[0005] The first fastening screw and the second fastening screw are arranged symmetrically.

[0006] The beneficial effects of this invention are as follows: Previously, workers had to place one foot on the surface of the container ship hatch cofferdam and the other on the end of the cargo hold guide rail. This resulted in a cramped working posture, limited freedom of movement, and an inability to work for extended periods, posing a significant risk of falls from heights. This new device secures the device to the top of the guide rail base via fastening screws and a stop plate; a wedge-shaped base acts on the end of the cargo hold guide rail from below. By using this step platform, the foot contact area is significantly increased, allowing for free movement and extended work periods. Leg fatigue is reduced, and the risk of falls is minimized.

[0011] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0012] like Figure 1 and Figure 2 The diagram illustrates a step device for adjusting the cover of a container ship. The container cargo hold facade is connected to a guide rail base 8 via a guide rail base connecting block 8b, and a cargo hold guide rail is mounted on the guide rail base 8. The device mainly includes an upper platform 1, fastening screws 2, a stop plate 3, a platform support 4, a lower platform 5, and a wedge-shaped base 6. The upper platform support beam 1a at the bottom of the upper platform 1 is connected to the lower platform 5 via the platform support 4, forming a stepped structure.

[0013] A first stop plate 3 and a second stop plate 3a are provided behind the upper platform support beam 1a. The guide rail base end face 8a is located between the upper platform support beam 1a and the first stop plate 3 and the second stop plate 3a. The first fastening bolt 2 and the second fastening bolt 2a pass through the upper platform support beam 1a and act on the guide rail base end face 8a, cooperating with the first stop plate 3 and the second stop plate 3a.

[0014] A lower platform support beam 5a is provided at the bottom of the lower platform 5, and a wedge-shaped base 6 is provided below the lower platform support beam 5a. The first wedge block 6a of the wedge base 6 interacts with the first inclined surface 7a of the guide rail at the end of the cargo hold guide rail 7, and the second wedge block 6b interacts with the second inclined surface 7b of the guide rail. The top plane 7c of the guide rail acts on the lower platform support beam 5a.

[0015] The first fastening screw 2 and the second fastening screw 2a are symmetrically arranged to ensure the stability of the device installation.

[0016] During operation, the guide rail base end of this device is inserted into the gap between the platform's fastening screws and the stop plate. By rotating the fastening screws, the stop plate and the guide rail base end are pressed together, thus securing the upper platform. The wedge-shaped base of this device is similar in shape to the end of the cargo hold guide rail, allowing it to sit downwards on top, thereby securing the lower platform. In summary, the entire device is securely fixed, allowing personnel to stand on the upper platform 1 and the lower platform 5 to perform related work. When working around this location at the container ship hatch, this platform is installed as a whole, ensuring that the guide rail base end is engaged between the fastening screws and the stop plate, while the wedge-shaped base rests on the end of the cargo hold guide rail.
