Hereinafter, a "cargo hatch cover opening and closing device" (hereinafter referred to as "opening and closing device") according to an embodiment of the present invention with reference to the drawings.

Figure 4 is a perspective view showing the structure of the hatch cover opening and closing device according to an embodiment of the present invention, Figures 5 and 6 are perspective views showing the detailed structure of the opening and closing device of Figure 4, Figure 7 is a perspective view showing a connection state of the rotary arm. .

The opening and closing device 100 of the present invention is installed on the deck 15 and is connected to one side (front in the moving direction) of the hatch cover 13 which is slidably movable on the hatch coaming 12.

On the deck 15 two posts 102 are mounted vertically. The post 102 is a device for reciprocating rotational movement of the rotary arms 104 respectively connected thereto by a predetermined angle, and may be arbitrarily rotated in the left and right directions by the rotational force generating means.

In the present invention, the motor 106 and the gearbox 108 are used as the rotational force generating means. The motor 106 is connected to the gearbox 108, which converts the direction and speed of the rotational force generated by the motor 106 and transmits the speed to the post 102. In addition, a clutch (not shown) may be installed inside the gearbox 108 to block transmission of the rotational force of the motor 106.

The post 102 is preferably positioned outward with respect to the extension of the two side lines of the hatchbucker 13. That is, the post 102 is not covered by the hatch cover 13 while the hatch cover 13 is open.

The rotary arm 104 is rotated together in accordance with the rotation of the post 102 connected to one side, the rotary arm 104 is a reciprocating rotational movement within a certain angle range. When the rotary arm 104 rotates closest to the hatch coaming 12, the hatch cover 13 is closed, and when the rotary arm 104 is rotated farthest from the hatch coaming 12, the hatch cover 13 is opened. By adjusting the rotation angle of the rotary arm 104 it is possible to easily adjust the opening width of the hatch cover (13).

The roller 120 is installed at the other end of the rotary arm 104, and the roller 120 slides in a straight line while being engaged with the front of the hatch cover 13. The structure and operation method of the roller unit 120 will be described later.

The rotational force from the gearbox 108 is transmitted to the post 102 by the rotational force transmission means. In the present invention, two

gears

110 and 112 are used as the rotational force transmission means.

As shown in FIGS. 6 and 7, the post 102 is provided with two

gears

110 and 112. The first gear 110 is directly connected to the gearbox 108, the second gear 112 is connected to the post 102. The two

gears

110 and 112 are engaged with each other and rotate, and the size of the first gear 110 and the second gear 112 may be different in order to convert the rotation speed converted into the primary gearbox 108 once again. Can be. In general, in order to move the rotary arm 104 at a very slow speed and a large force, the rotational speed of the post 102 must be very low, so that the size of the second gear 112 is larger than that of the first gear 110. Will be large.

In the present invention will be described as using the two gears (110, 112) as a rotational force transmission means, sprockets and chains may be used. That is, sprockets are installed in the gearbox 108 and the post 102, respectively, and the rotational force can be transmitted to the chain or the wire.

Alternatively, the post 102 may be directly installed in the gearbox 108 to directly transmit the rotational force of the motor 106 without passing through a separate power transmission means.

Various modifications may be made by those skilled in the art regarding the manner in which the rotational force of the motor 106 is transmitted to the post 102.

The bridge 114 is installed along a straight line extending in parallel with the moving direction of the hatch cover 13 from both ends of the hatch coaming 12. A rail 116 is installed on the upper portion of the bridge 114, and wheels 16 installed on both sides of the hatch cover 13 move along the rail 116. Therefore, the hatch cover 13 is opened and closed while slidingly moving back and forth along the bridge 114.

The wheel 16 is generally made of metal wheels, but a tubed tire may be used to reduce noise or vibration.

In the present invention has been described that the wheel 16 is installed on both sides of the hatch cover 13, the rail 116 is installed on the bridge 114, on the contrary, the rail 116 is provided on both sides of the hatch cover 13 Is installed, the bridge 114 may be provided with a wheel 16 to configure the hatch cover 13 to slide.

The bridge 114 extends by a predetermined length at both ends of the hatch coaming 12, and the length from the end of the hatch coaming 12 to the end of the bridge 114 may be shorter than the length of the hatch cover 13. At this time, when the hatch cover 13 is fully open, the front wheel 16 is in a state that is more outward than the end of the bridge 114 is floating in the air.

In the prior art, the bridge 114 is shorter than the length of the hatch cover 13, so if the wheel 16 of the hatch cover 13 is moved forward more than the end of the bridge 114, there is a risk that the hatch cover 13 falls down have. However, in the present invention, even if the front wheel 16 is in the air, the rotary arm 104 is connected to the front lower side of the hatch cover 13 to support the front end of the hatch cover 13. Therefore, the hatch cover 13 does not fall down. In the case of applying the present invention as described above, even if the length of the bridge 114 is shorter than in the prior art, there is no problem in the opening and closing operation of the hatch cover 13.

On the other hand, the rotary arm 104 is connected to the front of the hatch cover 13 to rotate, when the rotary arm 104 rotates in the opposite direction of the hatch coaming 12, the end of the rotary arm 104 is hatch coaming It moves in the direction away from (12). At this time, while the speed component in the front linear direction of the hatch cover 13 among the rotational speed components of the rotary arm 104 acts on the hatch cover 13, the hatch cover 13 performs linear motion.

As the rotary arm 104 continues to rotate, the hatch cover 13 moves, and the distance between the post 102 and the front surface of the hatch cover 13 changes, and the rotary arm 104 rotates the hatch cover ( The part in contact with the front of the 13) will be different. In order to allow the rotary arm 104 to smoothly move along the front portion of the hatch cover 13, a roller unit 120 is installed at the end of the rotary arm 104.

8 is a perspective view showing a coupling state of the roller portion and the H beam of the rotary arm, Figure 9 is a perspective view showing the structure of the roller portion.

The H beam 118 protrudes slightly in the front direction and is attached to the front of the hatch cover 13, and the H beam 118 is installed in a state in which the H-beam is horizontally laid. Therefore, one vertical plate is connected to the center line of two horizontal plates vertically and vertically based on the installed state. In addition, the roller unit 120 slides along the H beam 118 in a state where the vertical plate is gripped at both sides.

The roller unit 120 includes a U-shaped case 120a having a lower surface rotatably connected to the rotation shaft 122. The rotary shaft 122 is installed at the distal end of the rotary arm 104, and allows the case 120a to freely rotate according to the rotation of the rotary arm 104.

Four horizontal rollers 120b and four vertical rollers 120c are respectively provided on the upper portion of the U-shaped case 120a.

The horizontal roller 120b is installed in a state in which the rotating shaft is placed horizontally with respect to the ground to contact the lower surface of the upper horizontal plate of the H beam 118. The vertical rollers 120c are installed in a state in which the rotating shaft is perpendicular to the ground, and grips the center vertical plate of the H beam 118 from both sides.

10 is a cross-sectional view showing a coupling state of the vertical roller and the H beam, Figure 11 is a cross-sectional view showing a coupling state of the horizontal roller and the H beam.

Two horizontal rollers 120b and two vertical rollers 120c are installed on the left and right of the case 120a, respectively, facing each other. The distance between the left and right plates of the U-shaped case 120a is larger than the length of the horizontal plate of the H beam 118. Therefore, the H beam 118 is installed while the center vertical plate is sandwiched between the horizontal rollers 120b and the vertical rollers 120c.

Since the horizontal roller 120b is in contact with the lower surface of the upper horizontal plate of the H beam 118, the vertical load of the H beam 118 is applied to the horizontal roller 120b as it is. And although the vertical load is not applied to the vertical roller (120c), the roller 120 is guided so as to reciprocate the slide in a straight line along the center vertical plate of the H-beam 118.

Although the present invention has been described as driving two pairs of horizontal rollers 120b and vertical rollers 120c into the H beam 118 while the H beam 118 is laid horizontally, the H beam 118 is vertically driven. In the upright position, it may be supported by the roller in the vertical direction and the horizontal direction from the bottom.

Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the above-described technical configuration of the present invention may be embodied by those skilled in the art to which the present invention pertains without changing its technical spirit or essential features of the present invention. It will be appreciated that the present invention may be practiced as.
