[0029] Based on this, the present application proposes a rigid waterway bundling reinforcement equipment to improve the compatibility of the bundling reinforcement equipment, reduce the cost of fastening, and make it easy to operate, shorten the time used for reinforcement, and improve the efficiency and safety of equipment fastening.
[0030] Hereinafter, the present application will be described in detail through one or more specific embodiments.
[0031] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a rigid waterway binding reinforcement device includes a spiral fastener 10, a connector and at least one fastening chain 20, wherein the connector includes a connecting shackle 30 and an elephant foot connecting assembly 40, and one end of the fastening chain 20 is connected to the spiral fastener 10, and the other end is connected to the connector.
[0032] Specifically, the binding and reinforcement equipment is used to bind and reinforce cargo on the waterway, that is, to bind and reinforce cargo on the ship. The main body of the binding and reinforcement equipment is the mooring chain 20, and the connector is used to connect the mooring chain 20 to the hull, so that the mooring chain 20 can fix the cargo on the hull.
[0033] The spiral fastener 10 has a spiral fastening function, that is, it can shorten its own length through the spiral to enable the binding and reinforcement equipment to be tightened. One end of the fastening chain 20 is connected to the spiral fastener 10, which can enable the binding and reinforcement equipment to have a fastening function, facilitate the fastening of the binding and reinforcement equipment after bundling, and thus facilitate the binding and reinforcement of the goods by the binding and reinforcement equipment.
[0034] The elephant foot connection assembly 40 and the connection shackle 30 can both be stably connected to the structure on the hull, and the connection shackle 30 and the screw fastener 10 can both be stably connected to the cargo on the hull, and the connection is simple, which is conducive to improving the practicality of the binding reinforcement equipment.
[0035] Example 1, such as Figure 1As shown, the lashing and reinforcement equipment includes a screw fastener 10, an elephant foot connection assembly 40, and a securing chain 20.

The other end of the elephant foot connection assembly 40 is connected to a connecting member (e.g., an eye plate) on the hull. The other end of the screw fastener 10 is connected to the cargo to be lashed and reinforced. After the lashing and reinforcement equipment is connected, the screw fastener 10 is rotated to tighten the lashing and reinforcement equipment, completing the lashing and reinforcement of the cargo to be lashed and reinforced, so that it can be stably loaded on the hull.
[0036] Example 2: The binding and reinforcement equipment includes a screw fastener 10, an elephant foot connection assembly 40, a connecting shackle 30 and two securing chains 20. The two securing chains 20 are a first chain and a second chain respectively. The two ends of the screw fastener 10 are respectively connected to the ends of the first chain and the second chain to connect the first chain and the second chain together. The free end of the first chain is connected to the elephant foot connection assembly 40, and the elephant foot connection assembly 40 is connected to the ship board. The free end of the second chain is connected to the connecting shackle 30 to be connected to the cargo to be bound and reinforced through the connecting shackle 30.
[0037] Example three, the binding and reinforcement equipment includes a screw fastener 10, two connecting shackles 30, and two securing chains 20, the two connecting shackles 30 are respectively a first connecting shackle 30 and a second connecting shackle 30, the two securing chains 20 are respectively a first chain and a second chain, the two ends of the screw fastener 10 are respectively connected to the ends of the first chain and the second chain to connect the first chain and the second chain together, the free end of the first chain is connected to the first connecting shackle 30 to be connected to the cargo to be bound and reinforced through the first connecting shackle 30, the free end of the second chain is connected to the second connecting shackle 30 to be connected to the eye plate 01 on the ship board through the second connecting shackle 30, and then connected to the hull.
[0038] In this embodiment, a spiral fastener 10 is provided at one end of the mooring chain 20 and a connector is provided at the other end. The spiral fastener 10 not only has a connecting function but also a fastening function, and can easily adjust the tightness of the binding reinforcement equipment. The connector is used to connect to a fixed position in the mooring environment so that the mooring chain 20 can be bound and fixed. The connector includes a connecting shackle 30 and an elephant foot connecting assembly 40. In actual use, any one of the connectors can be selected according to the characteristics of the mooring environment to adapt to the mooring environment, thereby improving the practicality of the rigid water transport binding reinforcement equipment.
[0039] In some embodiments, as Figure 5 and Figure 6As shown, the connecting shackle 30 includes a small shackle 31 and a large shackle 32, the small shackle 31 includes a first U-shaped buckle 311 and a screw pin 312, and opposite screw holes are provided at both ends of the first U-shaped buckle 311, and the screw holes are used to be threadedly connected with the screw pin 312; the large shackle 32 includes a second U-shaped buckle 321 and a bolt 322, and opposite through holes are provided at both ends of the second U-shaped buckle 321, and the through holes are used for the bolt 322 to pass through and be threadedly connected with the nut.
[0040] Specifically, the connecting shackle 30 is used to connect the securing chain 20 to the securing position (the securing position can be on the hull or on the cargo to be tied and reinforced). The different sizes of the connecting shackle 30 can be adapted to the securing position and can be easily connected, which is conducive to improving the reinforcement efficiency of the tying and reinforcement equipment.
[0041] The small shackle 31 includes a first U-shaped buckle 311 and a screw pin 312. The first U-shaped buckle 311 is relatively small and is subject to relatively little stress during use. Providing the screw pin 312 to connect its opening (i.e., the two ends of the first U-shaped buckle 311) does not affect the normal connection and reinforcement of the small shackle 31, but also simplifies the connection of the screw pin 312, thereby facilitating user use. The large shackle 32 includes a second U-shaped buckle 321 and a bolt 322. The second U-shaped buckle 321 is relatively large and is subject to relatively great stress during use. Providing the bolt 322 and a nut at the opening of the second U-shaped buckle 321 to connect the two can enhance the strength of the opening of the second U-shaped buckle 321, thereby enhancing the strength of the large shackle 32, thereby improving its practicality.
[0042] In some embodiments, a protruding knob is provided at one end of the screw pin 312 , and the protruding knob is arranged to protrude relative to the screw hole.
[0043] Specifically, the screw pin 312 of the small shackle 31 is used to control the opening and closing of the opening of the first U-shaped buckle 311. The screw pin 312 is threadedly connected to the through hole at the opening of the first U-shaped buckle 311. When in use, the screw pin 312 needs to be screwed to control the opening and closing of the opening of the first U-shaped buckle 311. The protruding knob is provided at one end of the screw pin 312, which can facilitate the user to screw the screw pin 312, thereby facilitating the user to use the small shackle 31, thereby improving the practicality of the small shackle 31.
[0044] In some embodiments, as Figure 7 As shown, the screw fastener 10 includes a threaded adjustment sleeve 11 and a hooked screw 12 , wherein the hooked screw 12 is threadedly connected to the inner wall of the adjustment sleeve 11 , and one end of the hooked screw 12 having a hook head 121 is located outside the adjustment sleeve 11 .
[0045] Specifically, the inner wall of the adjusting sleeve 11 and the outer wall of the hooked screw 12 are both provided with threads. The hooked screw 12 can adjust its length outside the adjusting sleeve 11 under the action of the threads of the adjusting sleeve 11, thereby achieving the length adjustment of the screw fastener 10. When the length of the screw fastener 10 is shortened, the tightening effect of the screw fastener 10 can be achieved.
[0046] The hook head 121 of the hooked screw 12 is located outside the adjusting sleeve 11 to be connected to the fastening chain 20 or the fastening position. The setting of the hook head 121 of the hooked screw 12 can simplify the connection between the spiral fastener 10 and other structures, thereby helping to improve the practicality of the binding reinforcement equipment.
[0047] In some embodiments, the screw fastener 10 further includes a screwing handle 13 , and the screwing handle 13 is fixedly connected to the adjusting sleeve 11 .
[0048] Specifically, the screwing handle 13 is located on the adjusting sleeve 11, and the rotation of the screwing handle 13 can drive the rotation of the adjusting sleeve 11. Since the adjusting sleeve 11 is threadedly connected to the hook screw 12, when the adjusting sleeve rotates, the relative positions of the hook screw 12 and the adjusting sleeve 11 change. The setting of the screwing handle 13 can facilitate the user to rotate the adjusting sleeve 11, and then facilitate the user to adjust the length of the screw fastener 10 to adjust the tightness of the binding reinforcement equipment, which is conducive to improving the practicality of the binding reinforcement equipment.
[0049] In some embodiments, the screw fastener 10 includes two hooked screws 12 , and the two hooked screws 12 are respectively located at two ends of the adjusting sleeve 11 .
[0050] Specifically, the two hooked screws 12 are both screw structures with a hook head 121 at one end, and the ends of the two hooked screws 12 with the hook heads 121 are respectively located at both ends of the adjusting sleeve 11, and the ends of the two hooked screws 12 without the hook heads 121 are both located inside the adjusting sleeve 11 and are threadedly connected to the adjusting sleeve 11. The hook heads 121 of the two hooked screws 12 can facilitate the connection of the spiral fastener 10 with the fastening chain 20 or the fastening position, and the two hooked screws 12 are both threadedly connected to the adjusting sleeve 11. By rotating the adjusting sleeve 11, the two hooked screws 12 are moved relative to the adjusting sleeve 11, which is beneficial to improving the tightening efficiency of the spiral fastener 10, and then beneficial to improving the tightening efficiency and use efficiency of the binding and reinforcement equipment, and improving the practicality of the binding and reinforcement equipment.
[0051] In some embodiments, as Figure 8 and Figure 9 As shown, the elephant foot connection assembly 40 includes an elephant foot structure 41 and a base structure 42. The base structure 42 is provided with a connecting through hole 421. One end of the elephant foot structure 41 passing through the connecting through hole 421 is provided with a boss 411 to connect with the base structure 42.
[0052] Specifically, the base structure 42 is used to connect with the shipboard, and the elephant foot structure 41 is used to connect with the mooring chain 20. One end of the elephant foot structure 41 is set through the connecting hole 421, and is stably connected to the base structure 42 under the limiting action of the boss 411, so that the elephant foot connection assembly 40 stably connects the shipboard and the binding reinforcement equipment.
[0053] The elephant foot connection assembly 40 can connect the binding reinforcement equipment to the hull when there are no other connecting components on the ship, which can not only ensure the binding reinforcement of the binding reinforcement equipment, but also improve the environmental adaptability of the binding reinforcement equipment and enhance the practicality of the binding reinforcement equipment.
[0054] In some embodiments, the elephant foot structure 41 includes a connecting elephant foot 412 and a fixing triangle 413 , wherein one end of the connecting elephant foot 412 away from the fixing triangle 413 is disposed through the connecting through hole 421 .
[0055] Specifically, the boss 411 is provided at one end of the connecting elephant foot 412 away from the fixed triangle 413. The fixed triangle 413 is used to connect with the fastening chain 20. The fixed triangle 413 is a triangular ring structure, so that its connection with the fastening chain 20 can make the elephant foot structure 41 stably connected to the fastening chain 20 and facilitate connection, which is beneficial to improving the practicality of the binding reinforcement equipment.
[0056] In some embodiments, the fixing triangle 413 includes two adaptable connecting ends, and the two connecting ends are fixedly connected by a protective tube 4131.
[0057] Specifically, the fixing triangle 413 has two connecting ends, and the two connecting ends are arranged in abutment with each other. The protective tube 4131 is used to be sleeved on the periphery of the two connecting ends to close the opening of the fixing triangle 413 and maintain the annular structure.
[0058] When the fixing triangle 413 is connected to the fastening chain 20, the protective tube 4131 is moved to another position of the fixing triangle 413, and the two connecting ends of the fixing triangle 413 are pressed to form an opening. The connecting ends of the fastening chain 20 enter the fixing triangle 413 through the opening. Thereafter, the pressing of the two connecting ends is released, and the protective tube 4131 is moved to the two connecting ends to complete the connection between the fixing triangle 413 and the fastening chain 20, that is, the connection between the elephant foot connecting assembly 40 and the fastening chain 20 is completed.
[0059] In some embodiments, the connecting through hole 421 is a cross-shaped through hole, the center of the cross-shaped through hole is a circular hole, and the diameter of the circular hole is the same as the diameter of the boss 411.
[0060] Specifically, the elephant foot structure 41 can be connected to the base structure 42 by passing through the circular hole. The dimensions of other positions of the cross-shaped through hole are smaller than the diameter of the boss 411, so that the elephant foot structure 41 is stably connected to the base structure 42. Moreover, the elephant foot structure 41 can be located at different positions of the cross-shaped through hole to achieve connection with different positions of the base structure 42, which does not affect the stability of the elephant foot connection assembly 40 and can also improve the flexibility of the elephant foot connection assembly 40. The elephant foot structure 41 can flexibly adjust its position on the base structure 42 to adjust the fastening position of the fastening chain 20 connected to the elephant foot structure 41, thereby improving the practicality of the binding reinforcement equipment.
[0061] In summary, the rigid waterway binding reinforcement equipment provided by the present application has three major beneficial effects: 1. Increase the compatibility of cargo and ships: the cargo end can be connected to the fastening points of non-standard cargo and semi-standard cargo, and the ship fastening end can be fastened to ship structures such as eye plates, eye rings, fastening slots and foldable ground orders, thereby increasing the applicability of portable fastening equipment; 2. Reduce the transportation cost of multimodal transport fastening equipment: the ship connecting component, the spiral fastener 10, and the equipment connecting chain are separated from each other, and can be used in conjunction with aviation and railway reinforcement equipment through multiple connecting components. For example, in addition to being able to connect to the ship connecting component for water transportation, the lower part of the fastener can also be connected to the railway fastening chain; 3. Easy to operate: the ship connecting component, the spiral fastener 10, and the equipment connecting chain are each light in weight and can be operated by two people at the same time from both ends, thereby shortening the reinforcement time and improving the equipment fastening efficiency and safety.
