DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: See Figure 1 The utility model provides a technical solution: a ship hatch cover pressing device.

[0026] Among them, a cover plate 2 is installed on the top of the hatch cover 1, support columns 3 are arranged on the left and right sides of the hatch cover 1, a coaming column 301 is arranged below the support column 3 and close to the side of the hatch cover 1, a handle column 302 is arranged above the coaming column 301, a threaded hole is opened through the center of the handle column 302, a screw 304 is rotatably installed in the threaded hole, a cushion 305 is installed on the top of the handle column 302, a pressure block 306 is fixedly connected to the top of the screw 304, a handle 307 is arranged above the pressure block 306, a pressure plate 4 is arranged between the pressure block 306 and the soft cushion 305, and the pressure plate 4 is fixedly connected to a cross plate 402 near the center of the hatch cover 1.

[0027] In this embodiment, the entire support column 3 is divided into two parts. The coaming column 301 is attached to the coaming of the hatch cover 1 and is located below the support column 3. The handle column 302 is located at a position far away from the hatch cover 1 and above the support column 3 to prevent the cover 2 from colliding with the support column 3 when it is opened. The pressure plate 4 is U-shaped, and the circular avoidance 401 opened at the bottom is convenient for passing the screw 304. The circular avoidance 401 is opened toward the center of the hatch cover 1, so that the pressure plate 4 can move when the screw 304 is located at the center of the pressure plate 4. The center position of 01 fits with the screw rod 304, the top of the circular avoidance 401 fits with the cushion 305 at the bottom of the pressure block 306, and the handle 307 is turned to drive the screw rod 304 to rotate. Through the engagement of the thread on the screw rod 304 and the threaded hole, the entire screw rod 304 drives the pressure block 306 and the cushion 305 to move downward, reducing the gap between the cushion 305 and the top of the handle column 302, so that the cushion 305 squeezes the pressure plate 4, and the bottom of the pressure plate 4 rests on the cover plate 2, so that the pressure plate 4 applies a downward force to the cover plate 2 to press the cover plate 2.

[0028] A cushion 305 is also provided on the top of the handle column 302 , and the top of the cover plate 2 is horizontally higher than the cushion 305 on the top of the handle column 302 .

[0029] In this embodiment, when the pressing plate 4 is pressed downward by the pressing block 306, it first contacts the cover plate 2 and continues to move downward to press the cover plate 2. The soft pad 305 on the top of the handle column 302 can prevent the pressing plate 4 from being pressed down excessively, thereby reducing the damage caused by the pressing plate 4 hitting the handle column 302.

[0030] Among them, a hook 303 is fixedly connected to one side of the handle column 302 close to the enclosure column 301, and a crossbeam 404 is fixedly connected between the pressure plates 4.

[0031] In this embodiment, because the circular void 401 passes through the inner wall of the pressure plate 4, the pressure plate 4 can be movable, and the crossbeam 404 on the pressure plate 4 is hung on the hook 303, and the pressure plate 4 is placed vertically, so that the entire device is placed on both sides of the hatch cover 1, without affecting the opening and closing of the hatch cover 1 and the entry and exit of internal and external personnel and goods.

[0032] A through hole 403 is formed through the center of the cross plate 402 , a screw 5 is installed at the center of the through hole 403 , a ram nut 501 is rotatably installed on the surface of the screw 5 , and a countersunk head is formed at the bottom of the through hole 403 .

[0033] In this embodiment, the cross plates 402 on the two pressure plates 4 are aligned and snapped together, the through holes 403 are also aligned, and the screws 5 are passed through the through holes 403, the heads are installed in the countersunk heads and fixed, and the two cross plates 402 are locked by the ram nut.

[0034] The cushion 305 is made of rubber.

[0035] In this embodiment, the rubber material is relatively soft and fits the top of the pressing plate 4 , reducing the friction force generated by the pressing block 306 squeezing the pressing plate 4 when rotating with the screw rod 304 , so that the pressing block 306 presses the pressing plate 4 more tightly.

[0036] The enclosure column 301 of the support column 3 is partially welded to the enclosure of the hatch cover 1 .

[0037] In this embodiment, the support column 3 bonded and welded to the enclosure is more stable and will not shake due to the rotation of the handle 307, thereby improving stability.

[0038] Working principle: The operator closes the cover plate 2 of the hatch cover 1 from the outside, connects the cross plates 402 on the pressure plates 4 at both ends, passes the screws 304 through the holes 403, screws on the horn nuts 501 and locks them, so that the two pressure plates 4 are spliced ​​and placed flat on the top of the cover plate 2. At the same time, the handles 307 on both sides are turned to drive the screw rod 304 to rotate, and the threads on the screw rod 304 are engaged with the threads of the threaded holes, so that the screw rod 304 drives the pressure block 306 and the cushion 305 to move downward , the soft pad 305 squeezes the two ends of the pressure plate 4, and the bottom of the pressure plate 4 is placed on the cover plate 2, so that the pressure plate 4 applies a downward force to the cover plate 2, thereby pressing the cover plate 2 from the outside, and the handle 307 is turned in the opposite direction to loosen the pressure plate 4, and the screw 5 and the clevis nut 501 are removed, and the crossbeam 404 on the pressure plate 4 is hung on the hook 303. The pressure plate 4 is placed vertically, so that the entire device is placed on both sides of the hatch cover 1, which does not affect the opening and closing of the hatch cover 1 and the entry and exit of people and goods inside and outside.
