Since the hook 11 can be detachably connected to the fixed beam 2 of the ship through the clamping piece 111, the hook 11 can be installed according to the specific position of the construction area, so that the hanging of the safety belt is not limited by the position of the existing hanging point of the ship, the worker can basically work below the hanging device, and the use of the extension rope is avoided as much as possible, and the distance of free falling of the worker is reduced. Moreover, when the second hanging ring 42 on the safety belt moves during the work of the worker, the second hanging ring 42 moves along the first safety rope 3 together with the worker, so that the second hanging ring 42 is always located above the work point, the worker can avoid hitting the surrounding objects during falling, and the protection reliability of the worker is improved.

[0052] Further, in some embodiments, as shown in Figure 1 and Figure 2 , the fixed beam is a T row on the ship. The clamping piece 111 comprises a first plate 1111, a second plate 1112 and a third plate 1113 connected end to end, and a fourth plate 1114 connected perpendicularly to the third plate 1113 and extending away from the first plate 1111. The first plate 1111, the second plate 1112 and the third plate 1113 surround to form a U-shaped clamping groove 1115. The fourth plate 1114 is provided with a connecting hole 11141, and the hooking piece 112 is connected to the connecting hole 11141. When the hook 11 is installed, the clamping piece 111 can be clamped to one side of the T row through the U-shaped clamping groove 1115, and fixed with the T row through the locking piece 113. In this way, the hook 11 can be conveniently and effectively installed during construction, so that the hanging assembly 1 quickly reaches the use state, thereby improving the hanging efficiency of the safety belt; and the disassembly is also more convenient.

[0053] Further, in some embodiments, as shown in Figure 2 and Figure 3As shown, the hooking piece 112 includes a hook body 1121 and a connecting rod 1122. The hook body 1121 is in a U shape and both ends are provided with a first hole 11211 and a second hole 11212, the connecting rod 1122 passes through the first hole 11211 and the connecting hole 11141 and is threadedly connected with the second hole 11212, and the connecting rod 1122 is rotationally matched with the connecting hole 11141. The hooking piece 112 has a simple structure and is convenient to install, can realize quick connection of the hooking piece 112 and the clamping piece 111, further improves the installation efficiency, is convenient to produce and process, can be mass-produced, can even directly use existing standard parts, further reduces the cost, and can adaptively rotate relative to the clamping piece 111 under the pulling action of the operator, so that clamping is avoided.

[0054] Preferably, one end of the connecting rod 1122 is provided with a rotating handle, which facilitates the operator to rotate the connecting rod 1122 to install or dismount the connecting rod 1122.

[0057] Further, at least one side of the first elastic gasket 7 is provided with a first anti-skid structure, which can improve the friction between the groove and the fixed beam 2, and ensure the clamping stability of the clamping piece 111 and the fixed beam 2.

[0058] In some embodiments, the end of the locking piece 113 abutting against the fixed beam 2 is provided with a second elastic gasket. By providing the second elastic gasket, when the locking piece 113 is screwed into the third hole 11111, the locking piece 113 first makes soft contact with the fixed beam 2, and then abuts against the fixed beam 2, so as to protect the coating on the surface of the fixed beam 2 from being damaged when the clamping piece 111 is clamped. Further, the side of the second elastic gasket facing the fixed beam 2 is provided with a second anti-skid structure, and by providing the second anti-skid structure, the friction between the locking piece 113 and the fixed beam 2 can be improved, so as to ensure that the clamping piece 111 can be stably clamped with the fixed beam 2 through the locking piece 113, and the clamping stability of the clamping piece 111 and the fixed beam 2 is further improved.

[0059] In some embodiments, as shown in Figure 2 and Figure 3 the side of the first plate 1111 contacting the fixed beam 2 and the side of the third plate 1113 contacting the fixed beam 2 are both provided with a first elastic gasket 7, and the end of the locking piece 113 abutting against the fixed beam 2 is provided with a second elastic gasket. By simultaneously providing the first elastic gasket 7 and the second elastic gasket, it can be further ensured that the coating on the surface of the fixed beam 2 will not be damaged when the clamping piece 111 is clamped. For example, the first elastic gasket 7 can be bonded on the first plate 1111 and the third plate 1113. The first anti-skid structure can be anti-skid protrusions or anti-skid lines, etc. The second elastic gasket can be bonded on the end of the locking piece 113, and the second anti-skid structure can be anti-skid protrusions or anti-skid lines, etc.

[0060] Preferably, the end of the locking piece 113 abutting against the fixed beam 2 is provided with a chamfer, and when the locking piece 113 is screwed into the third hole 11111, the movement of the first elastic gasket 7 at the position of the third hole 11111 on the first plate 1111 during the screwing process can be avoided, so as to ensure that a gap is not easily formed between the first elastic gasket 7 and the first plate 1111 at the position of the third hole 11111.

[0061] Further, the connecting hole 11141 is provided with an elastic washer 8, and the connecting rod 1122 is rotatably arranged in the elastic washer 8, and such arrangement can reduce the wear of the connecting rod 1122 in daily use, and can also buffer the impact on the connecting rod 1122 when the worker falls. The elastic washer 8 is exemplarily a rubber ring.

For the sake of simplicity, only the differences between the second embodiment and the first embodiment are described. The difference lies in that the safety belt hanging device comprises hanging assemblies 1 and a third safety rope 6. The hanging assemblies 1 are spaced apart, each of the hanging assemblies 1 comprises a second safety rope 5 and two hooks 11 spaced apart. The hook 11 comprises a clamping piece 111 and a hooking piece 112 connected to each other, the clamping piece 111 is configured to be detachably connected to the fixed beam 2 of the ship, and the two ends of the second safety rope 5 are connected to the hooking pieces 112 of the two hooks 11, respectively.

[0064] One end of the third safety rope 6 is connected to the second safety rope 5 of one of the hanging assemblies 1, and the other end is connected to the second safety rope 5 of the other hanging assembly 1.

[0065] The first hanging ring 41 of the safety belt is hooked to any second safety rope 5, and the second hanging ring 42 is movably hooked to the third safety rope 6 along the third safety rope 6.

[0066] It can be understood that the safety belt hanging device provided by the embodiment comprises two hanging assemblies 1, each of the hanging assemblies 1 comprises two hooks 11 and a second safety rope 5 connected to the two hooks 11 at two ends, and a third safety rope 6 is arranged between the second safety ropes 5 of the two hanging assemblies 1, the first hanging ring 41 of the safety belt is hooked to any second safety rope 5, and the second hanging ring 42 is movably hooked to the third safety rope 6 along the third safety rope 6. Since the hook 11 can be detachably connected to the fixed beam 2 of the ship through the clamping piece 111, the hook 11 can be installed according to the specific position of the construction area, so that the hanging of the safety belt is not limited by the position of the existing hanging point of the ship, the worker can basically work below the hanging device, and the use of the extension rope is minimized, and the distance of the free falling of the worker is reduced. Moreover, the first hanging ring 41 of the safety belt is connected to one of the second safety ropes 5, and the second hanging ring 42 is movably connected to the third safety rope 6, so that when the worker moves during the work, the second hanging ring 42 of the safety belt can move together with the worker, so that the second hanging ring 42 is always located above the work point, avoiding the worker from colliding with the surrounding objects during the falling, and improving the protection reliability of the worker.
