Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, specifically to a self-locking sliding lift hatch opening and closing device. Background Technology

[0002] Currently, most existing ship hatches horizontally mounted on the deck are hinged doors, which require a large space on the outside of the entrance. Furthermore, once opened, the flipped-over hatch occupies space, affecting the operation of personnel and equipment on deck. Larger and heavier hatches require hydraulic cylinders for opening and closing, further consuming significant space within the cabin. Therefore, using a sliding door opening and closing method can greatly reduce space occupation. However, traditional sliding doors cannot achieve a flush opening with the deck surface when closed, and they struggle to meet sealing requirements. Even if sealing is achieved, the locking mechanism is complex, making the opening process cumbersome.

[0003] In summary, there is an urgent need for a simple locking mechanism that can make the hatch flush with the deck to lock the hatch, thus solving the problems existing in the prior art. Utility Model Content

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0027] See Figures 1-7As shown, a self-locking sliding lift door opening and closing device includes:

[0028] The door panel assembly 3 includes a door panel frame 301, a door panel 305 movably mounted on the door panel frame 301, a transmission component mounted on the door panel frame 301, and a drive component for driving the transmission component. The drive component is mounted on the door panel frame 301, and a guide wheel 304 is mounted on the side of the door panel 305 at the end away from the drive component.

[0029] The door frame assembly 1 is used to fix the bottom of the deck 4. The door frame assembly 1 includes a door frame body 101 and a fitting member. The fitting member is engaged with the transmission member and drives the door panel frame 301 to slide on the door frame assembly 1. The fitting member is fixed to the side of the door frame body 101 away from the opening.

[0030] The guide plate 2 is used to fix the bottom of the deck 4. The guide plate 2 is fixed to the side of the door frame assembly 1. The guide plate 2 has a guide groove 201 for the guide wheel 304 to slide and move up and down.

[0031] like Figure 4 As shown, the guide groove 201 is L-shaped and includes a vertical groove and a horizontal groove, with the vertical groove being away from the mating part.

[0032] Specifically, such as Figure 7 As shown, the cross-sectional shape of the door panel 305 is a trapezoid with a smaller top and a larger bottom, adapted to the edge of the opening. When the door panel 305 is closed, its upper surface can be flush with the deck 4, without affecting operations on the deck 4. In this embodiment, the door frame assembly 1 and the door panel frame 301 are made of welded steel pipes.

[0033] Preferably, the door panel 305 and the door panel frame 301 are rectangular with the same dimensions. The door panel 305 is movably connected to the door panel frame 301 by at least four connectors, and at least two of these connectors are arranged on one side of the door panel 305. In this embodiment, there are four connectors. The upper ends of the four connectors are located on both sides of the door panel 305 and at the four corners, while the lower ends of the four connectors are located on both sides of the door panel frame 301 and at the four corners.

[0034] Preferably, the connector includes a support rod 303 and two pins. Openings for the pins are provided at both ends of the support rod 303, on the door panel 305, and on the door panel frame 301. The support rod 303 movably connects the door panel 305 and the door panel frame 301 via the pins. The support rod 303 and the pins together form a four-bar linkage, so that during the sliding of the door panel 305, the support rod 303 tilts at the same angle, thereby achieving normal lifting and moving of the door panel 305.

[0035] Preferably, there are two guide wheels 304, located on both sides of the door panel 305 and at a position away from the drive member's pin. There are also two guide plates 2, fixed to both sides of the door frame assembly 1. During the sliding of the door panel 305, the support rod 303 is tilted. When the door panel 305 is closed in the opening, the guide wheels 304 are located at the top of the vertical groove. Specifically, the guide wheels 304 are rotatably mounted on both sides of the door panel 305 and at a position away from the drive member's pin. The guide wheels 304 extend beyond the support rod 303. After installation, the guide wheels 304 slide within the guide groove 201. During the sliding process of the door panel 305 via the transmission component, the guide wheel 304 slides within the horizontal groove. When the door panel 305 is closed in the opening, the guide wheel 304 rises in the vertical groove via the transmission component. When the door panel 305 opens from the opening, the guide wheel 304 descends in the vertical groove via the transmission component. The support rod 303 on the side furthest from the drive component is defined as the front arm, with the guide wheel 304 located at the top of the front arm. The support rod 303 on the side closest to the drive component is defined as the rear arm, which does not have a guide wheel 304. The rear arm is entirely located inside the guide plate 2. Due to the structural characteristics of the four-bar linkage, the rear arm can follow the front arm in the same trajectory, thus synchronously driving the door panel 305 to move. The bottom of the door panel 305 has a first ear plate for connecting the support rod 303, with an opening for the pin to pass through. This invention, through the design of the four-bar linkage and the guide groove 201 mechanism, realizes the lifting and opening / closing actions of the door panel 305.

[0036] Preferably, at least four pulleys 302 are installed at the bottom of the door panel frame 301, and at least two pulleys 302 are respectively arranged on both sides of the door panel frame 301. Two slide rails 103 are fixed on both sides of the door frame body 101 corresponding to the positions of the pulleys 302. Specifically, the door frame body 101 is rectangular, and uprights are provided at the four corners of the door frame body 101. The top of the uprights is fixed to the bottom surface of the deck 4, so that the opening is located inside the door frame body 101. The two slide rails 103 are respectively fixed to the side frames of the door frame body 101. The door panel frame 301 has two second ear plates corresponding to each pulley 302. The pulleys 302 are installed by rotating shafts. In this embodiment, there are four pulleys 302, which are located at the four corners of the door panel frame 301 and correspond to the slide rails 103.

[0037] Preferred, such as Figure 1 and Figure 2As shown, the transmission component is a gear 306, and the mating component is a rack 102 adapted to the gear 306. Specifically, the door frame body 101 has horizontal bars on both sides perpendicular to the slide rail 103. A central bar parallel to the slide rail 103 is vertically mounted on the horizontal bars. Both the horizontal bars and the central bar are located below the deck 4. The rack 102 is fixed to the central bar along its length. Since the rack 102 is parallel to the slide rail 103, the rotation of the gear 306 on the rack 102 can drive the door frame 301 to move. Through the cooperation of the gear 306 and the rack 102, transmission is achieved while also realizing the self-locking characteristic of the structure, thus avoiding the design of a locking mechanism.

[0038] Preferred, such as Figure 1 and Figure 3 As shown, the driving component is a motor 308, which is connected to a planetary reducer 307, which is connected to a gear 306. The motor 308, planetary reducer 307, and gear 306 are all located below the deck 4 and above the rack 102, regardless of whether the door panel 305 is closed or open. The reciprocating motion of the door panel 305 is achieved through the transmission and drive of the planetary reducer 307 and the motor 308.

[0039] Preferably, the door panel 305 has sealing strips around its four edges. When the door panel 305 is closed, the sealing strips on the door panel 305 can form a sealing structure by compression.

[0040] like Figure 5 As shown, in the closed state of the hatch, the door panel 305 is fitted with the deck 4, and the support rod 303 is in a vertical position. The hinge points at both ends of the support rod 303 are aligned with the direction of gravity, thus the mechanism is in a dead position and is self-locking. The gear 306 meshes with the rack 102, and is driven by the planetary reducer 307 and the motor 308 to achieve reciprocating motion.

[0041] like Figure 6 As shown, when the motor 308 drives the gear 306 to move clockwise, the gear 306 meshes with the rack 102. At the same time, under the guidance of the guide wheel 304 and the guide groove 201, the door frame 301 connected to the gear 306 moves backward, the lower hinge point of the support rod 303 moves backward, and the upper hinge point, under the action of the guide wheel 304, the L-shaped guide groove 201 on the guide plate 2 and the gravity of the door 305, first descends and then moves backward. Through the above actions, the opening action of the hatch descending and retracting is realized.

[0042] This utility model relates to a self-locking sliding lift hatch opening and closing device. Through the cooperation of the door panel assembly 3, the door frame assembly 1, and the guide plate 2, the sliding and lifting of the door panel 305 are achieved. This allows the hatch to be hidden inside the deck 4 when open and to seal the opening of the deck 4 when closed, solving the technical problem that the outer surface of the door panel 305 cannot be flush with the deck 4 when the sliding door is closed. This utility model can achieve self-locking without the need for a locking mechanism, greatly simplifying the structure. The structure is compact and does not occupy the upper space of the deck 4. When the door panel 305 is closed, its upper surface is flush with the deck 4, without affecting operations on the deck 4.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
