[0038] Container ships are an important form of modern shipping. With the continuous development of global trade, container ships, as one of the main means of transportation at sea, undertake a large number of cargo transportation tasks. The construction of the container ship cargo hold platform 20, due to its structural characteristics, is located between the hatch coaming and the cargo hold bottom, and is located above the cargo hold bottom. In the absence of guardrails and lack of intrinsic safety, it is very easy to fall from height. Therefore, construction workers must wear and hang safety belts in a standardized manner.
[0039] As the production of container ships progresses, all railings of the cargo hold platform 20 must be removed during the subsequent container test phase of container ship construction, making it impossible for on-site construction workers to install safety belts. The container test phase is close to the ship delivery node, and shipowners often request to clean and repair the cargo hold platform 20. However, at this time, there are no protective measures on the cargo hold platform 20, and operations are prohibited. Qualified personnel must be contacted to pull and install wire ropes, which consumes high labor and time costs and may also cause damage to the paint.
[0040] For this reason, Figures 1 to 3 As shown, this embodiment provides an auxiliary tooling 10 for a cargo hold platform, which is applied to a cargo hold platform 20 area of a container ship, and a railing socket 30 is provided on the side wall of the cargo hold platform 20. Specifically, the auxiliary tooling 10 for a cargo hold platform includes a rod body 1, a plug-in portion 2, a hook assembly 3 and a locking assembly 4. The plug-in portion 2 is connected to one end of the rod body 1, and the plug-in portion 2 is parallel to the rod body 1 and arranged at intervals. The plug-in portion 2 is configured to be inserted into the railing socket 30, the hook assembly 3 is arranged on the rod body 1, and both ends of a safety belt or a safety rope can be hung on the hook assembly 3. The locking assembly 4 is used to detachably fix the plug-in portion 2 in the railing socket 30.
[0041] When in use, the operator wears a safety belt and carries the auxiliary tooling 10 with him. The operator goes up to the cargo hold platform 20 through the middle compartment. First, the operator hangs the hook at one end of the safety belt on the middle compartment railing corresponding to the cargo hold platform 20 to be constructed before going to the cargo hold platform 20. Then, the operator holds the rod body 1 and inserts the plug-in part 2 into the railing socket 30 so that the connection position between the plug-in part 2 and the rod body 1 abuts against the end surface of the railing socket 30 to prevent it from shaking left and right. Then, the plug-in part 2 is fixed in the railing socket 30 by the locking component 4 to prevent the auxiliary tooling 10 from falling off. Subsequently, the hook component 3 is installed on the rod body 1 to hook the hook at the other end of the safety belt. Then, the hook of the safety belt on the middle compartment railing is removed and hung on the hook component 3. Then, each auxiliary tooling 10 is installed in the adjacent railing socket 30 in turn as a railing on the cargo hold platform 20. Only then can the operation of cleaning and repairing the cargo hold platform 20 be carried out.
[0042] It can be seen that the auxiliary tooling 10 for the cargo hold platform provided in this embodiment has a low manufacturing cost, can be carried by one person, is convenient and quick to use, can improve the safety of operations at heights, greatly shortens the construction period, saves labor costs, and can effectively ensure the construction quality and avoid waste caused by repairing damaged paint.
[0043] It should be noted that when the length of the safety belt is not enough, a safety rope can be connected to the hooks at both ends of the safety belt as an extension, and then the hooks at the ends of the safety rope can be hung on the hook assembly 3.
[0044] like Figure 3 As shown, the hook assembly 3 includes a lock buckle 31 and a speed differential 32. The rod body 1 is provided with two connection holes 11 spaced apart along its length direction. The lock buckle 31 is hung in one of the connection holes 11, and the speed differential 32 is hung in the other connection hole 11. One end of the safety belt or safety rope can be hung on the speed differential 32, and the other end of the safety belt or safety rope can be hung on the lock buckle 31. By hanging the two ends of the safety belt or safety rope separately, the balance can be maintained and the swing amplitude when falling from a height can be eliminated. By using the speed differential 32, the construction range can be guaranteed and effective protection can be provided against falling from a height.
[0045] Furthermore, the lock buckle 31 and the speed differential 32 are in opposite directions. This arrangement can ensure the force balance of the rod body 1 and extend the service life of the tooling.
[0046] like Figure 3 and Figure 4 As shown, the locking assembly 4 includes a fastener 41, a threaded hole 21 is provided at a position near the free end of the plug-in portion 2, a through hole 12 is provided at a position corresponding to the threaded hole 21 on the rod body 1, and the fastener 41 is passed through the through hole 12 and is threadedly connected to the threaded hole 21. In this way, the plug-in portion 2 can be stably plugged into the railing socket 30 to prevent the auxiliary tooling 10 from falling off, wherein the fastener 41 can be a bolt.
[0047] Furthermore, if Figure 3 As shown, the locking assembly 4 further includes a stopper 42, which is located in the gap between the plug-in portion 2 and the rod body 1, and a through hole is provided on the stopper 42 for the fastener 41 to pass through. Since the wall thickness of the rod body 1 is relatively thin, by sandwiching the stopper 42 between the plug-in portion 2 and the rod body 1, deformation of the rod body 1 can be avoided when the fastener 41 is locked.
[0048] In this embodiment, the plug-in portion 2 and the rod body 1 are integrally formed. The integrally formed structure can improve the strength of the overall structure, avoid the assembly process, and is easy to use.
[0049] like Figure 5As shown, a reinforcing rib 5 is provided inside the position where the plug-in portion 2 is connected to the rod body 1. By providing the reinforcing rib 5, the strength of the overall structure can be further improved and the service life of the tooling can be extended.
[0050] It should be noted that, since the construction area of the cargo hold platform 20 is located below the hatch coaming, when workers are working on the cargo hold platform 20, objects may fall from the edge of the hatch coaming and cause damage to the workers.
[0051] For this reason, Figure 1 and Figure 2 As shown, the present embodiment also provides a safety protection device, including an upper safety net 40 and the above-mentioned auxiliary tooling 10 for the cargo hold platform. The auxiliary tooling 10 for the cargo hold platform is arranged in two rows, namely a first row 101 and a second row 102. The hanging directions of the auxiliary tooling 10 in the first row 101 and the second row 102 are opposite. The safety belt or safety rope of the operator is hung on the auxiliary tooling 10 in the first row 101. The first row 101 and the second row 102 are respectively located on opposite sides of the cargo hold platform 20, and the first row 101 is higher than the second row 102. One side of the upper safety net 40 is connected to the top of the first row 101, and the other side is connected to the top of the second row 102.
[0052] Before installing the auxiliary tooling 10 of the first row 101, the operator first hangs the upper safety net 40 on the rod body 1 of the auxiliary tooling 10 of the first row 101, then turns the rod body 1 of the auxiliary tooling 10 of the first row 101 downward, hangs the plug-in part 2 in the railing socket 30, and then goes to the edge of the cargo hold platform 20, and sequentially installs the auxiliary tooling 10 of the second row 102. The rod body 1 of the auxiliary tooling 10 of the second row 102 is hung upward, and after installation, it can be used as a railing for edge operations. Finally, the upper safety net 40 is tied and connected to the rod body 1 of the second row 102. The upper safety net 40 can prevent objects above the working area from falling and causing physical damage to the construction personnel.
[0053] It should be noted that Figure 1 It can be seen that the cargo hold platform 20 is in a stepped shape, and each layer of the cargo hold platform 20 operates independently. The above operation process is described by taking one layer as an example, and the operation process of each layer is the same. Taking one layer of the cargo hold platform 20 as an example, the first row 101 is located on the inner side of the cargo hold platform 20, mainly used for hanging safety belts or safety ropes and connecting the upper safety net 40, and the second row 102 is located on the edge of the cargo hold platform 20, mainly used for serving as a railing and hanging the upper safety net 40.
[0054] Furthermore, if Figure 2As shown, the safety protection device further includes a lower safety net 50, one side of which is tied and connected to the top of the second row 102, and the other side of which is tied and connected to the bottom of the second row 102. By connecting the lower safety net 50 to the auxiliary tooling 10 of the second row 102, it can be used as a handrail when working near the edge, further improving safety.
[0055] In this embodiment, if Figure 2 As shown, three railing sockets 30 are provided on the upper and lower sides of each cargo hold platform 20, and the first row 101 and the second row 102 each include two auxiliary fixtures 10, which are respectively installed on the railing sockets 30 on both sides. In other embodiments, the first row 101 and the second row 102 may also include three auxiliary fixtures 10, which are respectively installed in three railing sockets 30. Of course, in other embodiments, the number of railing sockets 30 and auxiliary fixtures 10 may be more, which is not specifically limited here.
[0056] In an optional embodiment, when the operator works near the auxiliary tooling 10, both ends of the safety belt or safety rope can be hung on the same auxiliary tooling 10 for cargo hold platforms in the first row 101. In another optional embodiment, when the operator works between two auxiliary toolings 10, both ends of the safety belt or safety rope can be hung on two adjacent auxiliary toolings 10 for cargo hold platforms in the first row 101, respectively, which is more flexible to use.
[0057] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
