Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding, and in particular to a rope compartment entrance and exit device and a use method thereof. Background Art

[0002] Ropes are one of the equipments that are always available on ships. They are of various types and widely used. They are indispensable in the process of ship operation. Therefore, rope compartments are often installed on ships to store and manage ropes in an orderly manner. As ropes are frequently used, the hatch of the rope compartment should be able to be opened and closed at any time. The hatch cover of the rope compartment is often used as the entrance and exit device of the rope compartment; traditional hatch covers are mostly protruding structures, and their overall structure protrudes above the deck surface, which not only occupies the deck space, but also easily causes friction and collision with the staff or equipment on the deck; ships now use more embedded hatch covers, that is, the main part is buried under the deck, saving deck space, but most embedded hatch covers cannot completely hide their entirety, and their locking mechanism often uses multiple clips or bolts, which is inconvenient to open and close. In addition, they often cannot effectively seal the hatch.

[0003] In the document CN2023116417273, a hatch cover structure is disclosed, and a buried hatch cover structure scheme is proposed. In this scheme, the hatch cover is embedded in the groove and flush with the deck, which can perfectly hide the hatch cover in the deck, and its locking mechanism can effectively realize the locking of the hatch cover, and the hatch sealing effect is also relatively good. However, the hatch cover locking mechanism of this scheme is still relatively complicated, and the manufacturing cost of the hatch cover is relatively high; if this hatch cover is used as a rope in and out of the rope compartment entrance and exit device, when it is open, one side of the hatch cover is hinged to the hinge seat, which may affect the rope in and out of the rope compartment; and the rope compartment entrance and exit device must also meet the requirements of reducing rope wear and ensuring smooth use of ropes in and out of the rope compartment. Therefore, this type of hatch cover is not completely suitable as an entrance and exit device for a rope compartment.

[0004] Therefore, a new technical solution is needed to solve the above technical problems. Summary of the invention

[0005] In order to solve the above problems, the present invention discloses a rope cabin entrance and exit device and a method of using the same. A three-clip opening and closing mechanism is adopted to ensure good hatch locking and sealing effects. The device has a simple structure, low cost, and does not occupy deck space. It can effectively reduce the wear and tear caused by ropes entering and exiting the hatch.

[0007] By adopting the above technical solution, the clip is rotated so that the clip is located in the opening, thereby opening the cover plate, and then opening the hatch cover, so that the internal rope can be taken out or put in, the clip is located on the locking limit block, the cover plate covers the coaming, and the hatch is closed.

[0008] Preferably, the locking limit block is an overall right-angled trapezoidal block structure, which is arranged in a circle on one side of the annular baffle inside the enclosure. The locking limit block includes a slope, a platform and a small limit block. The slope and the small limit block are located on both sides of the platform. The small limit block is vertically located on the side of the right-angled side of the platform, and the downward trend of the slope is towards the position away from the small limit block.

[0009] By adopting the above technical solution, the locking limit block limits the clip. When the clip is rotated to the position of the locking limit block, the clip climbs up the slope to the platform. The small limit block limits the clip to prevent the clip from infinitely facing outward, thereby making the sealing strip in the cover plate close to the coaming to cover the hatch.

[0010] Preferably, a square ring groove is provided on the circumference of the cover plate end plate, a sealing strip is embedded in the square ring groove, a surrounding plate is abutted under the sealing strip, and a square ring groove body with a shape opposite to the square ring groove is provided on the circumference of the surrounding plate end, and the inner side edge of the square ring groove body abuts against the sealing strip.

[0011] By adopting the above technical solution, when the sealing strip in the cover plate squeezes the coaming, it means that the cover plate exerts a downward force on the coaming, and the cover plate is tightly abutted against the coaming to seal the hatch.

[0016] Preferably, the clip is in the shape of a long rod, the end of which is located on the locking limit block and does not exceed the inner side of the square ring groove body. The clip is located at the opening position, the enclosure is in contact with the sealing strip, but the sealing strip is not under stress.

[0017] By adopting the above technical solution, the clip is located exactly on the inner side of the square ring groove. When the clip is located at the opening position, the cover plate can be lifted upward when the handle is lifted upward. When the clip runs to the locking limit block, the cover plate is pressed toward the enclosure.

[0018] Preferably, a square protrusion is provided above the part of the main shaft located above the cover plate, and a circle of annular protrusion is provided at the bottom of the square protrusion. The size of the annular protrusion is larger than the size of the through groove of the cover plate and is just stuck in the upper part of the through groove. The square protrusion is socketed with the sleeve at the bottom of the handle, and the handle is in an inverted L shape.

[0019] By adopting the above technical solution, the sleeve at the bottom of the handle and the square protrusion at the top of the main shaft are socketed, and the annular protrusion at the bottom of the square protrusion can prevent the handle from passing through the cover plate when the clip is squeezed inward, thereby achieving the squeezing of the cover plate. After the work is completed, the handle can be removed from the main shaft, and the entire device will not protrude from the surface of the ship deck.

[0020] Preferably, the anti-wear bushing is barrel-shaped, the middle part of the anti-wear bushing is cylindrical, and its diameter is adapted to the diameter of the annular baffle. The upper part of the cylinder is a convex ring plate facing outward, and the bottom of the convex ring plate is clamped on the ship deck above the shroud.

[0021] By adopting the above technical solution, when the cover plate is removed from the enclosure, the anti-wear bushing is put on the enclosure to prevent the rope from causing damage to the enclosure when it is taken out, thereby playing a role in protecting the enclosure.

[0022] Preferably, the cover plate is provided with an inwardly recessed square groove, and a lifting handle is provided in the square groove.

[0023] By adopting the above technical solution, when there is no pressure between the cover plate and the enclosure plate, the cover plate can be removed from the enclosure plate more conveniently and quickly by lifting the lifting handle upwards.

[0024] A method for using a rope cabin entrance and exit device comprises the following steps: Opening the hatch: Step 1: Connect the sleeve below the handle to the square protrusion above the main shaft; Step 2: Turn the handle, the handle drives the main shaft to rotate the three clips, and the three clips slide down along the slope of the locking limit block to reach the opening position of the annular baffle in the enclosure; Step 3: Lift the handle upwards and remove the cover. The hatch cover is now open. Step 4: Put the anti-wear bushing on the enclosure; To close the hatch: S1: Remove the anti-wear bushing from above the enclosure; S2: Use the lifting handle to place the cover plate on the enclosure, with the sealing strip of the cover plate aligned with the inner side plate of the square ring groove body of the enclosure; S3: Connect the sleeve below the handle with the square protrusion above the main shaft; S4: Turn the handle, the handle drives the main shaft to rotate the three clips, the three clips climb along the trapezoidal locking limit block slope, reach the locking limit block small limit block for limit, and the hatch cover is locked.

[0025] The benefits of the present invention are as follows: 1. The hatch cover of the present invention adopts a fixed three-clip opening and closing mechanism.

The handle is removed from the main shaft, and the deck surface is almost flat, and it will not affect other parts, so the hatch is sealed. The operation is simple and convenient, and the hatch cover has strong sealing performance.

[0026] 2. When the rope needs to enter or exit the hatch, the clamp only needs to be rotated to the opening position, and then the cover plate is removed from the coaming as a whole, and then the anti-wear bushing is put on. In this way, when the rope enters or exits, the coaming can be protected, and there are no other obstacles near the rope, which will not affect the rope entering or exiting the hatch, thereby improving the efficiency of the rope entering or exiting.
