[0001] This application relates to the technical field of hatch cover protection devices, and in particular to a pole device and railing. Background Technology
[0002] Before opening ship hatches, temporary protective railings must be installed to prevent personnel from falling into the water while walking on the hatches. These railings consist of multiple vertical posts. The posts and hatches are mostly welded together and cannot be disassembled, posing a problem of non-reusability. Therefore, the existing posts cannot be reused. Utility Model Content
[0003] The purpose of this application is to provide a pole erection device to solve the problem that existing poles cannot be reused.
[0004] This application provides a pole erection device, including a base and a pole. The base includes an internally threaded section, which is used to pass through and connect to the top plate of the hatch cover, and is also used to connect to the side plate of the hatch cover. The pole includes an externally threaded section, which is inserted into the base and screwed to the internally threaded section.
[0005] Optionally, the base includes an installation tube, a pad, and a water pipe. The installation tube is used to pass through and connect to the top plate of the hatch cover. The pad is connected to the installation tube, and the water pipe is connected to the pad. The water pipe is used to connect to the side plate of the hatch cover.
[0006] Optionally, the internal thread section is provided on the mounting tube.
[0007] Optionally, the bottom surface of the mounting tube abuts against the top surface of the pad, and when the base is fixed to the top plate of the hatch cover, the height of the mounting tube is equal to the distance between the top surface of the hatch cover and the top surface of the pad.
[0008] Optionally, the length of the external thread segment is equal to the length of the internal thread segment, and the bottom end of the internal thread segment is spaced apart from the bottom surface of the mounting tube.
[0009] Optionally, the pad includes a drainage hole, which is connected to the mounting pipe and the drainage pipe.
[0010] Optionally, when the upright is in the tightened state, the upright and the pad are spaced apart.
[0011] Optionally, the mounting tube is vertically arranged, and the projection of the pad on the horizontal plane is located within the projection of the mounting tube on the horizontal plane.
[0012] Optionally, the pole includes a body and three open rings, the three open rings being spaced apart from each other on the body, each open ring being used to allow a steel wire rope to pass through.
[0013] This application also provides a railing, including multiple sets of the aforementioned upright devices and multiple steel wire ropes. The multiple sets of upright devices are spaced apart and arranged in a ring on the top plate and side plate of the hatch cover. The multiple steel wire ropes are spaced apart from each other.
[0014] The beneficial effects of this application are as follows: by setting a base and an upright, the base includes an internally threaded section for passing through and connecting to the top plate of the hatch cover, and also for connecting to the side plates of the hatch cover. The upright includes an externally threaded section that is inserted into the base and screwed to the internally threaded section. Because the upright and the base are threadedly connected, and the base can connect to both the top and side plates of the hatch cover, the upright and the hatch cover are detachably connected. After use, the upright can be removed from the hatch cover for reuse.

[0043] Please also refer to Figures 1 to 4 This embodiment provides a pole device 1, including a base 10 and a pole 11. The base 10 includes an internal thread section 1000, which is used to pass through and connect to the hatch cover top plate 2, and is also used to connect to the hatch cover side plate 3. The pole 11 includes an external thread section 1100, which is inserted into the base 10 and screwed to the internal thread section 1000. Since the pole 11 and the base 10 are threadedly connected, the base 10 can connect to the hatch cover top plate 2 and the hatch cover side plate 3, so the pole 11 and the hatch cover (the hatch cover includes the hatch cover top plate 2 and the hatch cover side plate 3, hereinafter the same) are detachably connected. After the pole 11 is used, it can be removed from the hatch cover for reuse.
[0044] like Figure 4 As shown, the specific structure of the base 10 is described in the following description of the embodiment. The top end of the base 10 is used to pass through the hatch cover top plate 2 and is connected to the hatch cover top plate 2 by welding. The base 10 is made of steel. An internal threaded section 1000 is provided on the top of the base 10. The hatch cover top plate 2 is horizontally arranged and is made of steel. The bottom end of the base 10 passes through the hatch cover side plate 3 and is connected to the hatch cover side plate 3 by welding. The upright 11 is vertically arranged, and an external threaded section 1100 is provided at the bottom of the upright 11. The upright 11 is made of stainless steel. The hatch cover side plate 3 is vertically arranged and is made of steel. The hatch cover side plate 3 and the hatch cover top plate 2 are connected by welding.
[0045] like Figure 4 As shown, optionally, the base 10 includes an installation pipe 100, a pad 101, and a drain pipe 102. The installation pipe 100 is used to pass through and connect to the hatch top plate 2. The pad 101 is connected to the installation pipe 100, and the drain pipe 102 is connected to the pad 101. The drain pipe 102 is used to connect to the hatch side plate 3. This arrangement avoids direct contact between the installation pipe 100 and the drain pipe 102, and prevents stress concentration on the installation pipe 100 on the drain pipe 102.
[0046] Please also refer to Figure 1 and Figure 4The mounting tube 100 is a round tube made of steel. The mounting tube 100 is vertically installed. The top end of the mounting tube 100 is used to pass through the hatch cover top plate 2 and is connected to the hatch cover top plate 2 by welding. When the mounting tube 100 is fixed to the hatch cover top plate 2, the mounting tube 100 and the hatch cover side plate 3 are spaced apart. The hatch cover top plate 2 is provided with a through hole 20, the diameter of which is the same as the outer diameter of the mounting tube 100. The through hole 20 allows the mounting tube 100 to pass through.
[0047] Please also refer to Figure 1 , Figure 4 and Figure 5 The pad 101 is annular and made of steel. The pad 101 is connected to the bottom surface of the mounting pipe 100 by welding. The water pipe 102 is L-shaped and made of steel. The top surface of the water pipe 102 is connected to the pad 101 by welding, and the right end of the water pipe 102 is used to pass through the hatch cover side plate 3 and is connected to the hatch cover side plate 3 by welding. The right end of the water pipe 102 can communicate with the drain pipe, which is used to discharge water outside the ship.
[0048] like Figure 4 As shown, the pad 101 is located between the mounting pipe 100 and the drain pipe 102. The drain pipe 102 is used to drain water accumulated in the upright 11 and the base 10 from the hatch cover (the top of the upright 11 is open, so water will accumulate. After the upright 11 is removed, water will also accumulate in the base 10). The base 10 consists of the mounting pipe 100, the pad 101, and the drain pipe 102. The area below the hatch cover top plate 2 and to the left of the hatch cover side plate 3 is preferably open to facilitate the installation personnel to enter from the left side to weld the mounting pipe 100 to the hatch cover top plate 2, the pad 101 to the mounting pipe 100 and the drain pipe 102, and the drain pipe 102 to the hatch cover side plate 3.
[0049] Please also refer to Figure 1 and Figure 4 Optionally, the internal thread section 1000 is provided on the mounting pipe 100. Since the mounting pipe 100 can be connected to both the hatch top plate 2 and the hatch side plate 3 at the same time, the internal thread section 1000 being provided on the mounting pipe 100 makes the fixation of the upright 11 more stable.
[0050] like Figure 4 As shown, optionally, the bottom surface of the mounting tube 100 abuts against the top surface of the pad 101. When the base 10 is fixed to the hatch top plate 2, the height of the mounting tube 100 is equal to the distance between the top surface of the hatch top plate 2 and the top surface of the pad 101. This arrangement allows the mounting tube 100 to be coplanar with the top surface of the hatch top plate 2 when fixed, thus preventing the mounting tube 100 from protruding upwards and tripping or injuring personnel passing by it. The height of the mounting tube 100 is the distance from its top surface to its bottom surface.
[0051] Please also refer to Figure 1 and Figure 4 Optionally, the length of the external thread section 1100 and the length of the internal thread section 1000 are equal, and the bottom end of the internal thread section 1000 is spaced apart from the bottom surface of the mounting tube 100. With this configuration, when the upright 11 is tightened, both the external thread section 1100 and the internal thread section 1000 are threaded together axially on the upright 11, avoiding the possibility of misfitting threads due to the different lengths of the external thread section 1100 and the internal thread section 1000, thus preventing the threads from being underutilized.
[0052] like Figure 4 As shown, optionally, the pad 101 includes a drainage hole 1010, which is connected to the mounting pipe 100 and the drainage pipe 102. This arrangement prevents water accumulation inside the upright 11 and the base 10, which could lead to rust and damage to the upright 11 and the base 10. The drainage hole 1010 penetrates the upper and lower surfaces of the pad 101.
[0053] like Figure 4 As shown, optionally, when the upright 11 is tightened, the upright 11 and the pad 101 are spaced apart. This arrangement prevents the upright 11 from pressing against the pad 101 and causing damage to the pad 101 when it is tightened. The spaced arrangement between the upright 11 and the pad 101 means that the external thread section 1100 and the pad 101 are spaced apart when tightened.
[0054] like Figure 4 As shown, optionally, the mounting tube 100 is vertically arranged, and the projection of the pad 101 on the horizontal plane is located within the projection of the mounting tube 100 on the horizontal plane. This arrangement can reduce the material used for the pad 101 and save manufacturing costs.
[0055] Please also refer to Figure 2 and Figure 4 Optionally, the upright 11 includes a body 110 and three open rings 111. The three open rings 111 are spaced apart on the body 110, and each open ring 111 is used for the steel wire rope 4 to pass through. Setting three open rings 111 on the body 110 results in a higher density of open rings 111, allowing for smaller spacing between adjacent steel wire ropes 4 at different heights, thus improving the effect of preventing personnel from falling. The body 110 is a round tube made of steel. An externally threaded section 1100 is located at the bottom of the body 110. The open rings 111 are annular and made of steel. Each open ring 111 is connected to the body 110 by welding.
[0056] Please also refer to Figure 2 and Figure 6In another embodiment, a railing is provided, comprising multiple sets of upright devices 1 as described in the preceding embodiments and multiple steel wire ropes 4. The multiple sets of upright devices 1 are spaced apart and arranged in a ring on the hatch top plate 2 and hatch side plate 3. The multiple steel wire ropes 4 are spaced apart from each other. Since all uprights 11 are screwed to the hatch top plate 2 and hatch side plate 3, all uprights 11 can be reused, saving the overall material cost of the railing. The steel wire ropes 4 are preferably 6mm stainless steel wire ropes.
[0057] Please also refer to Figure 2 and Figure 6 Both ends of the wire rope 4 are detachably fixed to the corresponding open rings 111 by wire rope buckles 5 (also called cat claws). Taking the uppermost wire rope 4 as an example, its left end passes through the open ring 111 at the top of the leftmost upright 11 and is then folded in half, and then the folded wire rope 4 is fixed with wire rope buckles 5.
[0058] Please also refer to Figure 2 and Figure 6 If a rectangular ring-shaped fence is required, a pole 11 needs to be installed at each of the four corners of the hatch top plate 2, and four sections of steel wire rope 4 need to be installed at each height (12 steel wire ropes 4 are required for three layers). The two ends of each section of steel wire rope 4 are detachably fixed to the pole 11 at the corner using steel wire rope clips 5. Each section of steel wire rope 4 can pass through the open rings 111 on the other poles 11 outside the corners. The central axis of each open ring 111 on the poles 11 at the four corners is perpendicular to the central axis of each open ring 111 on the poles 11 not at the four corners.
[0059] Please also refer to Figure 2 and Figure 6 Alternatively, at each height, a section of wire rope 4 can be threaded through the open ring 111 on each upright 11 (three wire ropes 4 are needed for three layers). The start and end points of the wire rope 4 are detachably secured with wire rope clips 5. When disassembling the wire rope 4, simply unfasten the wire rope clips 5 and pull the wire rope 4 away.
[0060] Please also refer to Figure 2 and Figure 6 When personnel need to walk on the hatch top plate 2, multiple sets of upright devices 1 are arranged in a ring (e.g., a rectangular ring) on the hatch top plate 2 to form a fence. This makes it less likely for personnel to fall into the water from the hatch top plate 2 while moving within the fence. When the railing is not in use, each base 110 and each wire rope 4 can be removed, and the base 10 can be left on the hatch top plate 2 and the hatch side plate 3.
