In the prior art, during the construction of a bulk carrier, after the hull of the bulk carrier is built, the personnel working in the large cargo hold generally retract and release the used belt from the deck surface. For retracting and releasing from the deck lifting opening, it is also possible to retract and release from the hatch coaming, and directly pull upwards at the lifting opening or the hatch coaming. The height from the deck to the large cargo hold may be 20 - 30 meters. When directly retracting and releasing the belt, there is a great potential safety hazard of personnel falling. And during the pulling process, it is not convenient to observe the situation of the pulled belt, and because it is both laborious and cannot stop during the pulling process, it is easy to cause exhaustion and the defect that the pulled belt slips down again. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects in the prior art that safety accidents are likely to occur when pulling the belt at the deck lifting opening, and it is inconvenient to observe and is laborious and easy to cause the object to slip during the process, and to provide a belt traction device for a cargo ship deck lifting opening.

[0004] The present invention solves the above technical problem through the following technical solutions:

[0005] A belt traction device for a cargo ship deck lifting opening, which includes a cover plate and a belt traction mechanism. An opening for a traction member to pass through is provided on the cover plate; the belt traction mechanism includes a ratchet component and a support frame. The lower end of the ratchet component is connected to the upper end of the support frame, and the lower end of the support frame is connected to the deck and / or the cover plate. The ratchet component is located directly above the opening.

[0006] In this solution, the belt traction device for a cargo ship deck lifting opening can: 1. change the force application method of pulling upwards through the lifting opening, saving effort for the staff; 2. by setting it to a one-way rotation method, avoid the risk of the belt slipping down due to the staff's negligence; 3. the staff does not need to be too close to the lifting opening, eliminating the occurrence of falling accidents and improving safety; 4. it can be processed with a small amount of materials, with low cost; 5. one can be installed in each large cargo hold, which is convenient to use and is convenient for demolition, recycling, and maintenance.

[0007] Preferably, the ratchet component includes a curved rod frame, a ratchet, and a blade. The curved rod frame is connected to the support frame. The curved rod frame is provided with a plurality of bearings. The ratchet and the blade are respectively hinged to the plurality of bearings. Both the ratchet and the blade are disposed within the curved rod frame.

[0008] In this solution, the curved rod frame can place the ratchet and the blade therein, and provides bearings so that the ratchet and the blade can cooperate with each other to achieve the one-way rotation of the ratchet. The connection between the curved rod frame and the support frame enables the components of the entire belt traction mechanism to cooperate to achieve their functions and complete the belt traction work. This ratchet component has a simple structure, is easy to manufacture, and has strong practicability.

[0009] Preferably, the blade has a stop end, and the ratchet has a stop groove. The ratchet rotates to pull the belt, and the stop end slides along the outer wall of the ratchet against the rotation direction.

[0015] Preferably, the support frame further includes a diagonal brace. One end of the diagonal brace is connected to the outer wall of the support rod, and the other end of the diagonal brace is welded to the deck. The diagonal brace is used to provide an oblique acting force to the support rod.

[0016] In this solution, the diagonal brace is obliquely connected to the support rod, and its actual function is to provide an oblique force to the support rod, so that the entire belt traction mechanism is stabilized, providing a stable device for the subsequent belt pulling operation.

[0017] Preferably, the support frame further comprises a plurality of belt piles, wherein the plurality of belt piles are connected to the outer wall of the support rod, and the belt can be bolted to the plurality of belt piles.

[0018] In this solution, the main function of the belt pile is that when the belt is pulled up, if the staff is exhausted or cannot continue due to other things, the belt can be tied into a knot through the belt pile to prevent the belt from sliding down, which can serve as a double insurance with the ratchet component.

[0019] Preferably, the support frame also includes a fixing plate, the hanging port is welded with a flange ring, a plurality of bolts are arranged on the flange ring, the fixing plate is fixed to the flange ring by the bolts, and the bottom end of the support rod is welded to the fixing plate.

[0020] In this solution, the fixing plate can provide a fixed support point for the support rod, and the fixing plate is fixed to the flange ring at the lifting port, so that the support frame can be stably connected to the plane where the deck is located, providing a convenient device for the staff to pull the belt.

[0021] Preferably, one end of the cover is hinged to the flange ring, and a handle is provided on the top of the other end of the cover. In this solution, the cover is connected to the flange ring by a hinged connection, so that the cover can be opened at any time, which is convenient for observing the status of the pulled belt or passing other large objects through the hanging opening. At the same time, the setting of the handle provides a fulcrum, which facilitates the operation of opening the cover by flipping it; at the same time, it also plays the role of covering the hanging opening, preventing the staff from falling, and improving safety.

[0022] Preferably, the cover plate is detachably connected to the flange ring, and the cover plate is in a grid shape. In this solution, the cover plate is arranged in a grid shape and is detachably connected to the flange ring, which can be opened at any time to facilitate the transfer of other objects, and is also convenient for observing the situation of the pulled belt or other objects, while also improving safety and preventing people from falling.

[0051] The present invention will be more clearly and completely described below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments hereby.

[0052] Embodiment 1

[0053] As Figure 1 shown, Embodiment 1 of the present invention discloses a belt traction device 0 for a bulk carrier deck lifting port, which includes a cover plate 1 and a belt traction mechanism 2. An opening 12 for the traction member to pass through is provided on the cover plate 1; the belt traction mechanism 2 includes a ratchet 212 member 21 and a support frame 22. The lower end of the ratchet 212 member 21 is connected to the upper end of the support frame 22, and the lower end of the support frame 22 is connected to the deck and / or the cover plate 1. The ratchet 212 member 21 is located directly above the opening 12. The belt traction device 0 for the bulk carrier deck lifting port can: 1. change the force application method for pulling upward through the lifting port, saving effort for the staff; 2. avoid the risk of the belt slipping down due to the negligence of the staff by setting it to a one-way rotation method; 3. the staff does not need to be too close to the lifting port, eliminating the occurrence of falling accidents and improving safety; 4. it can be processed with a small amount of materials, with low cost; 5. one can be installed in each large bin, which is convenient to use and is easy to disassemble, recycle, and maintain.

[0054] Specifically, in this Embodiment 1, the diameter of the deck lifting port is set to 800 mm, the height from the deck to the plane where the belt is located is 20 - 30 meters, and the diameter of the flange ring 3 is also set to be equal to or greater than 800 mm. Through the belt traction mechanism 2, the belt is pulled from the large bin to the plane where the deck is located, and the force application direction for pulling the belt before is changed by the belt traction mechanism 2. It is changed from pulling upward near the lifting port before to being able to pull downward away from the lifting port through the belt traction mechanism 2. The change in the force application direction is both labor-saving and safe. Specifically, one end of the traction member or rope is passed through the middle of the ratchet 212 member 21 and lowered through the opening 12. The rope is tied firmly to the belt below the large bin and then the rope is pulled. After one end of the belt is pulled up, the belt is pulled until the entire belt is pulled up. Multiple belts can repeat the above operation.

[0055] As Figure 2As shown, the ratchet 212 component 21 includes a curved rod frame 211, a ratchet 212, and a blade 213. The curved rod frame 211 is connected to the support frame 22. There are several bearings on the curved rod frame 211. The ratchet 212 and the blade 213 are respectively hinged on several bearings. Both the ratchet 212 and the blade 213 are arranged inside the curved rod frame 211. The curved rod frame 211 can place the ratchet 212 and the blade 213 therein and provides bearings so that the ratchet 212 and the blade 213 can cooperate with each other to achieve the one-way rotation of the ratchet 212. The connection between the curved rod frame 211 and the support frame 22 enables the components of the entire belt traction mechanism 2 to achieve functions through cooperation and complete the belt traction work. The ratchet 212 component 21 has a simple structure, is easy to manufacture, and has strong practicability.

[0056] Specifically, the shape of the curved rod frame 211 is U-shaped, and the frame bodies at both ends thereof surround the ratchet 212 and the blade 213. There are two ratchets 212, which are respectively arranged at both ends of the bearing and are located at the middle position of the curved rod frame 211. There is one blade 213, which is also connected to the bearing, and the length of the blade 213 is consistent with the length between the two ratchets 212. Both ends of the blade 213 can abut against the outer walls of the two ratchets 212 to play a stopping role.

[0057] As Figure 3 shown, the blade 213 has a stopping end 2131, and the ratchet 212 has a stopping groove 2121. The ratchet 212 rotates to pull the belt, and the stopping end 2131 slides along the outer wall of the ratchet 212 against the rotation direction; when the belt slips, the stopping end 2131 inserts into the stopping groove 2121 and abuts against the inner wall of the stopping groove 2121 to stop the ratchet 212. The combination of the ratchet 212 and the blade 213 solves the problem of laboriousness and danger in pulling the belt in the prior art. The ratchet 212 can only rotate in the direction of pulling the belt. If the belt slides reversely, the blade 213 will insert into the stopping groove 2121 on the ratchet 212 to play a role in fixing the ratchet 212.

[0058] Specifically, the ratchet 212 is provided with 4 stopping grooves 2121. The stopping grooves 2121 are of an irregular shape, and the left end of the groove opening is higher than the right end. The stopping end 2131 of the blade 213 is a tip and can be clamped in the stopping groove 2121. When the ratchet 212 rotates in the direction of pulling the belt onto the deck, the stopping end 2131 of the blade 213 slides on the outer wall of the ratchet 212 and will not insert into the stopping groove 2121. When the ratchet 212 rotates in the reverse direction causing the belt to move away from the deck, at this time the stopping end 2131 can insert into any one of the stopping grooves 2121 and simultaneously prevent the ratchet 212 from continuing to rotate, playing a role in preventing the belt from slipping. The staff can dial the blade 213 away from the stopping groove 2121 and continue to pull the belt.

[0059] The blade 213 is made of ferromagnetic material. A magnet 2112 is provided at the upper end of the curved rod holder 211. The blade 213 can be turned upward so that the stop end 2131 is magnetically attracted to the magnet 2112. When the blade 213 is idle, it can be turned upward and magnetically attracted to the curved rod holder 211. By placing the blade 213 at different positions according to different usage stages, it can reduce the wear of the blade 213 and the ratchet 212 due to friction, and at the same time play a role in beautifying the ratchet 212 component 21.

[0060] As Figure 1 and Figure 2 shown, the support frame 22 includes a support rod 221 and a top plate 222. The curved rod holder 211 has a bottom plate 2111. The top end of the support rod 221, the top plate 222 and the bottom plate 2111 are connected by bolts. The stable connection of the three is achieved through bolts, thus forming a complete belt traction mechanism 2, which can solve the technical problems to be solved in this application and achieve the due technical effects.

[0061] Specifically, the bottom of the curved rod holder 211 is the bottom plate 2111. Two bolts are fixed on the bottom plate 2111. The two bolts are inserted into the top plate 222 and the top end of the support rod 221. The top plate 222 is welded to the top end of the support rod 221, paying attention to the direction. Fix the three together to prevent loosening, and the screw holes at the punching positions of the three are matched.

[0062] The support frame 22 further includes a diagonal brace 223. One end of the diagonal brace 223 is connected to the outer wall of the support rod 221, and the other end of the diagonal brace 223 is welded to the deck. The diagonal brace 223 is used to provide an oblique acting force to the support rod 221. The diagonal brace 223 is obliquely connected to the support rod 221. Its actual function is to provide an oblique acting force to the support rod 221, so that the entire belt traction mechanism 2 is stabilized, providing a stable device for the subsequent operation of pulling the belt.

[0063] Specifically, the lengths of the support rod 221 and the diagonal brace 223 are appropriate. The support rod 221 is welded to the middle position of the fixed plate 225. An appropriate inclination is set according to the distance between the opening 12 on the cover plate 1 and the bolt. The top end of the support rod 221 is located above the opening 12, and the ratchet 212 component 21 fixed to the top end is perpendicular to the opening 12, so that the traction member can pull the belt upward in the vertical direction. The angle of the diagonal brace 223 is adjusted according to the position of the support rod 221. Two diagonal braces 223 are symmetrically installed. The lower end of the diagonal brace 223 is cut into an inclined surface, and the length is determined according to the position of pulling the belt, ensuring that when pulling the belt, the belt is exactly in the middle position of the opening 12.

[0064] As Figure 1As shown, the support frame 22 further includes a number of belt piles 224. The number of belt piles 224 are connected to the outer wall of the support rod 221, and the belt can be tied to the number of belt piles 224. The main function of the belt pile 224 is that when the belt is pulled up, if the staff is exhausted or there are other things that prevent them from continuing, the belt can be tied into a knot through the belt pile 224 to prevent the belt from slipping. In this way, it can play a dual insurance role with the ratchet 212 component 21.

[0065] Specifically, the round steel is bent into a "7 - shaped", and two "7 - shaped" belt piles 224 are welded to the support rod 221 vertically. When the belt is wound around it, an "8 - shaped" method is used to tie it tightly to prevent the belt from slipping.

[0066] The support frame 22 further includes a fixed plate 225. A flange ring 3 is welded at the lifting opening, and a number of bolts are provided on the flange ring 3. The fixed plate 225 is fixed to the flange ring 3 through bolts, and the bottom end of the support rod 221 is welded and fixed to the fixed plate 225. The fixed plate 225 can provide a fixed support point for the support rod 221. At the same time, the fixed plate 225 is fixed to the flange ring 3 at the lifting opening, so that the support frame 22 can be stably connected to the plane where the deck is located, providing a convenient device for the staff to tow the belt.

[0067] Specifically, the fixed plate 225 of the lower support frame 22 is installed on the bolts of the flange ring 3 and tightened with nuts. The bolts of the fixed plate 225 are set to match the bolts on the flange ring 3 to avoid loosening.

[0068] As Figure 4 shown, one end of the cover plate 1 is hinged to the flange ring 3, and a handle 11 is provided at the top of the other end of the cover plate 1. The cover plate 1 is connected to the flange ring 3 in a hinged manner, which can realize opening the cover plate 1 at any time for easy observation of the situation of the towed belt or for passing other larger - sized objects through the lifting opening. At the same time, the setting of the handle 11 provides a point of force, facilitating the operation of opening the cover plate 1 by flipping. At the same time, it also plays a role of covering the lifting opening, preventing the staff from falling and improving safety.

[0069] Embodiment 2

[0070] As Figure 5 shown, the same parts of the structure of the belt towing device for the lifting opening of the bulk carrier deck in this Embodiment 2 as those in Embodiment 1 will not be repeated, and only the differences will be described. In this Embodiment 2, the cover plate 1 is detachably connected to the flange ring 3, and the cover plate 1 is grid - shaped. The cover plate 1 is set to be grid - shaped and detachably connected to the flange ring 3, which can not only be opened at any time for convenient passing of other objects, but also facilitate the observation of the towed belt or other objects. At the same time, it also improves safety and prevents personnel from falling.
