Description

Technical Field

[0001] This utility model relates to the field of hatch cover technology, and in particular to a folding hatch cover system. Background Technology

[0002] To prevent cargo from getting damp, contaminated, or lost, hatch covers are usually installed on cargo ships. Folding hatch covers can be classified into hydraulically driven, direct-pull, and cable-driven types according to their driving method. Depending on the actual use, different types of folding hatch covers with different driving methods can be used.

[0003] Chinese Patent Publication No. CN216232833U discloses a folding hatch cover opening and locking device, including a hatch, a fixed hatch cover, and a movable hatch cover. The hatch is equipped with a locking device, which includes a supporting hydraulic cylinder. By pushing the hydraulic cylinder, the deflection of the supporting hydraulic cylinder can be adjusted so that the supporting hydraulic cylinder deflects 90 degrees, perpendicular to the hatch, thereby providing support and preventing the fixed hatch cover and the movable hatch cover from falling and causing injury to personnel when the adjusting hydraulic cylinder goes out of control.

[0004] The existing technical solution has the following shortcomings: the hatch cover needs to be operated in conjunction with multiple hydraulic cylinders during operation in order to further support the hatch cover after it is opened, so as to prevent the hatch cover from falling back unexpectedly. This makes its overall structure more complex. Furthermore, the use of multiple hydraulic cylinders increases the processing procedures of the operating system, which can easily lead to a decrease in the sensitivity of the hatch cover locking support response. Therefore, there is room for improvement. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology, which has a relatively complex structure. This utility model proposes a folding hatch cover system.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a folding hatch cover system, comprising: a hatch coaming, a support base provided on one side of the hatch coaming, a hatch cover A hinged to the top of the support base, a hatch cover B hinged to one side of the hatch cover A, inclined plates fixed on both sides of the top of the hatch coaming near the support base, guide grooves being formed on the top of the inclined plates and the hatch coaming, rollers being rotatably connected to the ends of both sides of the hatch cover B away from the hatch cover A, the outer sides of the rollers being inserted into the interior of the adjacent guide grooves, and hydraulic telescopic rods hinged to both outer sides of the hatch cover A near the support base, one end of each hydraulic telescopic rod being connected to the hatch coaming. The outer sides are hinged together. One end of each hydraulic telescopic rod is fixed with an infrared speed sensor, and the other end of each hydraulic telescopic rod is fixed with a signal receiving component. The two inner side walls of the hatch coaming are provided with storage slots. The inner wall of the hatch coaming outside the storage slots is fixed with guide frames. The inside of each guide frame is equipped with a movable box. The movable box slides back and forth between the guide frame and the storage slot. Interception components are equidistantly arranged inside the movable box. Springs A are evenly connected between the movable box and the storage slot. An electromagnet is installed at the center of the movable box near the storage slot. The signal receiving component, infrared speed sensor, and interception components are all electrically connected.

[0007] Preferably, the length of hatch cover A is less than the length of hatch cover B, and the sum of the lengths of hatch cover A and hatch cover B is greater than the opening length of the hatch coaming.

[0008] Preferably, the end of the guide groove near the inclined plate is inclined upward, and the other end of the guide groove is horizontal.

[0009] Preferably, spring A is compressed, and a magnetically attractable metal plate is fixed to the inner wall of the electromagnet in the storage slot. When the electromagnet is energized, it attracts the magnetically attractable metal plate, and the electromagnetic attraction is greater than the elastic force of spring A.

[0010] Preferably, the interception component includes a spring B fixed to the bottom of the inside of the mobile box, an interception block fixed to the top of the spring B, and a slider fixed to the outside of the interception block. The slider is slidably installed in a groove on the inner wall of the mobile box.

[0011] Preferably, the interceptor block slides vertically, the moving box slides horizontally, the side of the interceptor block closest to the hatch A is a vertical surface, the side of the interceptor block furthest from the hatch A is a slope one, and the side of the interceptor block closest to the storage slot is a slope two.

[0012] Compared with the prior art, the beneficial effects of this utility model include:

[0013] The retraction speed of the hydraulic telescopic rod is detected by the cooperation of an infrared speed sensor and a signal receiving component. When abnormal retraction is detected, the electromagnet is automatically de-energized. This, in conjunction with the guide groove, spring B, and intercepting block, enables the intercepting block to automatically pop out. The vertical surface of the intercepting block can intercept the downward fall of the front side of the hatch B, preventing the hatch from closing unexpectedly in the event of a malfunction of the hydraulic telescopic rod, thus reducing the risk of injury to personnel entering and exiting. This method has a simple structure, a fast automatic response speed, and better operational reliability because no power supply is required during the interception response period.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0021] To address the drawback of the complex structure of existing technologies, the following solution is disclosed, specifically as follows: Figures 1-4 As shown:

[0022] A folding hatch cover system includes: a hatch coaming 1; a support base 2 is provided on one side of the hatch coaming 1; a hatch cover A3 is hinged to the top of the support base 2; a hatch cover B4 is hinged to one side of the hatch cover A3; inclined plates 5 are fixed to both sides of the top of the hatch coaming 1 near the support base 2; guide grooves 6 are formed on both sides of the hatch cover B4 away from the hatch cover A3; rollers 7 are rotatably connected to the outer sides of the rollers 7, which are inserted into the interior of the adjacent guide grooves 6; hydraulic telescopic rods 8 are hinged to both outer sides of the hatch cover A3 near the support base 2; and one end of each hydraulic telescopic rod is... The hatch coaming 1 is hinged to the outside. One end of the hydraulic telescopic rod 8 is fixed with an infrared speed sensor 9, and the other end of the hydraulic telescopic rod 8 is fixed with a signal receiving component 10. The two inner side walls of the hatch coaming 1 are provided with storage slots 12. The inner wall of the hatch coaming 1 outside the storage slots 12 is fixed with a guide frame 11. The guide frame 11 is installed with a movable box 13. The movable box 13 slides back and forth between the guide frame 11 and the storage slot 12. The movable box 13 is provided with interception components 15 at equal intervals. The movable box 13 and the storage slot 12 are evenly connected with springs A16. An electromagnet 14 is installed at the center of the movable box 13 near the storage slot 12. The infrared speed sensor 9 and the interception component 15 are electrically connected.

[0023] The length of hatch cover A3 is less than the length of hatch cover B4, and the sum of the lengths of hatch cover A3 and hatch cover B4 is greater than the opening length of hatch coaming 1;

[0024] The guide groove 6 is inclined upward at one end near the inclined plate 5, and the other end of the guide groove 6 is horizontal;

[0025] Specifically, such as Figure 1 As shown, an inclined structure is used to ensure that the roller 7 rolls forward automatically during the closing phase of the hatch coaming 1, thus ensuring the stability of the closing movement of hatch cover B4 and hatch cover A3.

[0026] Spring A16 is in a compressed state. A magnetically attractable metal plate is fixed to the inner wall of the storage groove 12 relative to the electromagnet 14. When the electromagnet 14 is energized, it attracts the magnetically attractable metal plate. The electromagnetic attraction force is greater than the elastic force of spring A16.

[0027] Specifically, such as Figure 2 , Figure 3 As shown, by using the electromagnetic attraction of the electromagnet 14, the movable box 13 can automatically move into the storage slot 12, thereby causing the interception component 15 to retract into the storage slot 12 for storage, thereby releasing the interception effect on the hatch cover B4 falling back and ensuring the smooth closure of the hatch coaming 1.

[0028] The interception assembly 15 includes a spring B152 fixed inside the bottom of the movable box 13, an interception block 151 fixed to the top of the spring B152, a slider 153 fixed to the outside of the interception block 151, and the slider 153 slidably installed in a groove on the inner wall of the movable box 13.

[0029] Specifically, such as Figure 4 As shown, the slider 153 is used to ensure that the intercepting block 151 moves only up and down inside the moving box 13, so that the tilting and sliding of the hatch B4 is easily intercepted by the intercepting block 151.

[0030] The interceptor block 151 slides vertically, the moving box 13 slides horizontally, the side of the interceptor block 151 closest to the hatch A3 is a vertical surface, the side of the interceptor block 151 furthest from the hatch A3 is a slope one, and the side of the interceptor block 151 closest to the storage slot 12 is a slope two.

[0031] Specifically, such as Figure 4 As shown, when the electromagnet 14 is magnetically attracted by the inclined plane 2, the edge of the storage slot 12 can press against the intercepting block 151 when the moving box 13 slides into the storage slot 12, causing the intercepting block 151 to automatically retract into the interior of the moving box 13, thereby promoting the moving box 13 to retract into the storage slot 12, so as to release the intercepting effect of the intercepting component 15 on the hatch B4.

[0032] In this embodiment, when the hydraulic telescopic rod 8 is abnormally retracted during use, its abnormal retraction speed is detected by the infrared speed sensor 9 and transmitted to the signal receiving component 10. This causes the signal receiving component 10 to automatically control the electromagnet 14 to de-energize, causing the electromagnet 14 to lose its magnetic attraction to the inner wall of the storage slot 12. This causes the moving box 13 to move outward under the elastic compression of the spring A16 and move onto the guide frame 11. Since the obstruction at the top of the intercepting block 151 disappears at this time, the intercepting block 151 is pushed upward under the action of the spring B152. At this time, the hatch cover B4 falls abnormally, causing the inclined plate 5 to roll from the inclined surface of the guide slot 6 to the horizontal surface. This causes the front side of the hatch cover B4 to move to the vertical surface position of the intercepting block 151 and be blocked. Since the abnormal falling speed of the hatch cover B4 is different, multiple intercepting blocks 151 are used to intercept the hatch cover B4 at different falling positions, thereby preventing the hatch coaming 1 from closing directly and avoiding personnel injury.

[0033] When the hatch B4 falls back normally, the retraction rate of the signal receiving component 10 detected by the infrared speed sensor 9 is normal, thereby enabling the signal receiving component 10 to control the electromagnet 14 to be energized normally, causing the moving box 13 to move towards the storage slot 12 under the magnetic attraction, and causing the intercepting block 151 to move and retract into the moving box 13 under the action of the inclined plane, so as to ensure the normal fall of the hatch B4.

[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
