DETAILED DESCRIPTION

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0050] The purpose of the present invention is to provide a rapid mooring device and method to solve the problems existing in the above-mentioned prior art, improve the safety and efficiency of the operation, and help improve the transportation efficiency.

[0051] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0052] Example 1

[0053] like Figures 1 to 22As shown, this embodiment provides a rapid mooring device 100, comprising a winding mechanism 1, a first mooring chain 2, a second mooring chain 3 and a one-way mechanism 4, wherein: the winding mechanism 1 comprises a base 101 and a rotating shaft 102 rotatably connected to the base 101; one end of the first mooring chain 2 is connected to the rotating shaft 102, and the first mooring chain 2 and the rotating shaft 102 can synchronously rotate forward around the axis of the rotating shaft 102 under the action of an external force and tighten the first mooring chain 2 on the rotating shaft 102, and the first mooring chain 2 and the rotating shaft 102 can synchronously reverse around the axis of the rotating shaft 102 under the action of an external force and release the first mooring chain 2; one end of the second mooring chain 3 is connected to the base 101; the one-way mechanism 4 can limit the reverse rotation of the rotating shaft 102 around its own axis; the one-way mechanism 4 can release the restriction on the reverse rotation of the rotating shaft 102 under the action of an external force. During use, the quick mooring device 100 is first left with sufficient length to facilitate the fixed connection of the end of the first mooring chain 2 away from the second mooring chain 3 and the end of the second mooring chain 3 away from the first mooring chain 2 to the two connected parts. Then, the first mooring chain 2 is rotated forwardly about the axis of the rotating shaft 102 to reel in the first mooring chain 2, thereby completing the mooring of one connected part to the other. When it is necessary to release the mooring (release the state of the connected part being moored), the restriction on the reverse rotation of the rotating shaft 102 by the one-way mechanism 4 is released, allowing the rotating shaft 102 to reverse around its own axis, allowing the first mooring chain 2 to be released from the rotating shaft 102, thereby facilitating the removal of the first mooring chain 2 and / or the second mooring chain 3 from the corresponding connected part. The one-way mechanism 4 of this embodiment can ensure that the rotating shaft 102 can only rotate forward and cannot reverse during the winding process, preventing the rotating shaft 102 from reversing and causing the first mooring chain 2 that has been wound to loosen, thereby improving the safety and efficiency of the operation; at the same time, when the rotating shaft 102 stops rotating forward, due to the limiting effect of the one-way mechanism 4, the rotating shaft 102 cannot reverse, thereby locking the position of the rotating shaft 102, so that the part to be connected is moored at the set position, and no additional locking operation is required, which further improves the mooring speed and is conducive to improving the transportation efficiency.

[0054] In some embodiments, the one-way mechanism 4 includes a pawl 401, a ratchet 402, and an elastic member 403. The ratchet 402 is sleeved around the rotating shaft 102 and fixedly connected to the rotating shaft 102. One end of the pawl 401 is connected to the base 101 for rotation about a first axis. The two ends of the elastic member 403 are fixedly connected to the pawl 401 and the base 101, respectively. The other end of the pawl 401 can contact the ratchet 402 under the tension of the elastic member 403. The pawl 401, by contacting the ratchet 402, can restrict the rotating shaft 102 from rotating in the opposite direction about its own axis. Under the action of an external force, the pawl 401 can rotate about the first axis away from the ratchet 402, thereby releasing the restriction on the reverse rotation of the rotating shaft 102. When the first tethering chain 2 is tightened, the pawl 401 contacts the ratchet 402, allowing the ratchet 402 to rotate only in the forward direction, thereby causing the rotating shaft 102 to rotate in the forward direction in one direction. When it is necessary to release the mooring, the pawl 401 is rotated to disengage from the ratchet 402 and release the locking effect on the rotating shaft 102, so that the rotating shaft 102 can be reversed, and the first mooring chain 2 can move in the loosening direction to achieve rapid release of the mooring; when the external force is removed, the pawl 401 can be reset under the action of the elastic component 403 and maintain contact with the ratchet 402, thereby improving the convenience of use.

[0055] In some embodiments, the one-way mechanism 4 further includes a driving mechanism 5, which is fixedly connected to the pawl 401; the driving mechanism 5 can drive the pawl 401 to rotate around the first axis toward a side away from the ratchet wheel 402. Figure 2 As shown, when the torque applied by the driving mechanism 5 to the pawl 401 is greater than the clockwise torque generated by the elastic component 403, the pawl 401 can be driven to rotate counterclockwise around the first axis, so that the ratchet 402 and the pawl 401 are out of contact.

[0056] In some embodiments, the first axis and the axis of the rotation shaft 102 are parallel to each other.

[0057] In some embodiments, a length adjustment mechanism 6 is further included, and both ends of the length adjustment mechanism 6 are respectively connected to the second mooring chain 3 and the base 101. The length adjustment mechanism 6 can make the second mooring chain 3 and the base 101 move toward or in the opposite direction to adjust the pre-tensioning force of the quick mooring device 100 to ensure sufficient locking between the two parts to be connected.

[0058] In some embodiments, the length adjustment mechanism 6 includes a connecting seat 601, an adjusting member 602 and a first connecting rod 603, the connecting seat 601 includes a second connecting rod 604, the two ends of the adjusting member 602 are respectively threadedly connected to one end of the first connecting rod 603 and one end of the second connecting rod 604, the rotation direction of the threads on the first connecting rod 603 and the second connecting rod 604 are opposite, the other end of the first connecting rod 603 is fixedly connected to the first mooring chain 2, and the other end of the second connecting rod 604 is fixedly connected to the base 101. Since the adjusting member 602 is threadedly connected to the first connecting rod 603 and the second connecting rod 604, rotating the adjusting member 602 can convert the rotation of the adjusting member 602 into linear motion of the first connecting rod 603 and the second connecting rod 604. Since the rotation directions of the threads on the first connecting rod 603 and the second connecting rod 604 are opposite, the first connecting rod 603 and the second connecting rod 604 can move closer to or away from each other to fine-tune the distance between the first tethering chain 2 and the base 101, thereby achieving the function of fine-tuning the degree of locking and loosening.

[0059] In some embodiments, the adjusting member 602 is annular, with two threaded holes 605 disposed on its outer wall. Each threaded hole 605 communicates with an annular cavity 606 of the adjusting member 602. The two threaded holes 605 are coaxial and are threadedly connected to the first connecting rod 603 and the second connecting rod 604, respectively. The threaded holes 605 are through-holes, and the annular shape of the adjusting member 602 allows the first and second connecting rods 603, 604 to pass through the threaded holes 605 and into the annular cavity 606 during adjustment. The annular cavity 606 provides space for movement of the first and second connecting rods 603, 604, resulting in a simple structure and ease of use.

[0060] In some embodiments, a mooring plug 7 and a hook 8 are further included. The mooring plug 7 is fixedly connected to the end of the second mooring chain 3 away from the first mooring chain 2, and the hook 8 is fixedly connected to the end of the first mooring chain 2 away from the second mooring chain 3. The mooring plug 7 and hook 8 are used to quickly connect two connected components.

[0061] In some embodiments, a handle 9 is further included. The first mooring chain 2 includes a sprocket 201 and a chain body 202. The sprocket 201 is sleeved on the rotating shaft 102 and fixedly connected to the rotating shaft 102. The sprocket 201 is fixedly connected to one end of the chain body 202. The chain body 202 can be engaged with the sprocket 201. The handle 9 is fixedly connected to one end of the chain body 202 close to the sprocket 201. The handle 9 can apply a force to the chain body 202 and make the chain body 202 engage and tighten on the sprocket 201. When the chain body 202 engages and tightens on the sprocket 201, the sprocket 201 and the rotating shaft 102 can rotate forward around the axis of the rotating shaft 102. The handle 9 applies a force to the chain body 202 that tightens the chain body 202, causing the chain body 202 to mesh with the sprocket 201 and tighten. Since the chain body 202 is meshed with the sprocket 201, the sprocket 201 can rotate synchronously, driving the rotating shaft 102 to rotate, and the rotating shaft 102 drives the ratchet 402 to rotate, achieving unidirectional tightening under the action of the pawl 401. This embodiment uses the handle 9 to directly pull the chain body 202 to achieve tightening, which can achieve rapid tightening and is conducive to improving work efficiency.

[0062] In some embodiments, the sprocket 201 and the chain body 202 are fixedly connected at one end away from the hook 8. The sprocket 201 and the rotating shaft 102 are fixedly connected via a flat key 10. The combination of the sprocket 201 and the rotating shaft 102 is connected to the base 101. The sprocket 201 and the ratchet 402 are spaced apart along the axial direction of the rotating shaft 102. The ratchet 402 is mounted on one end of the rotating shaft 102 via the flat key 10 and secured to the rotating shaft 102 via a set screw 11. The pawl 401 is connected to the base 101 via a shaft, the axis of which is the first axis. The elastic member 403 is a spring that can pull and press the pawl 401 onto the ratchet 402. The mooring plug 7, the first mooring chain 2, and the first connecting rod 603 are welded together in sequence. The chain body 202 and the hook 8 are connected as a whole via a pin, and the chain body 202 and the handle 9 are connected as a whole via welding.

[0063] In some embodiments, the connection base 601 further includes a connection plate, which is fixedly connected to the second connection rod 604. The second connection rod 604 is perpendicular to the connection plate to form a T-shape of the connection base 601. The connection plate is fixedly connected to the base 101 by fasteners such as bolts 607.

[0064] In some embodiments, the driving mechanism 5 is a thumb screw. By pushing the thumb screw, the driving mechanism 5 drives the pawl 401 to rotate around the first axis toward a side away from the ratchet wheel 402 under the action of an external force.

[0065] The quick mooring device 100 provided in this embodiment has good versatility. By rationally designing the relevant structural dimensions, it can be used for the quick mooring of various items and mechanisms such as storage racks, ships, and airplanes. Taking the mooring of a storage rack as an example, the two parts to be connected are the storage rack and the equipment to be moored by the storage rack. The equipment to be moored by the storage rack is provided with a mooring hole. The mooring plug 7 is used to connect to the mooring hole, and the hook 8 is used to connect to the storage rack. The quick mooring device 100 provided in this embodiment is easy to use and convenient for quick installation and disassembly. Most components of the device are easy to process and manufacture, and are easy to mass-produce. Preferably, the size structure of the bolt 607, handle 9, limit screw 11, spring and flat key 10 is selected in accordance with the corresponding national standards.

[0069] S2. Release the restriction of the one-way mechanism 4 on the reverse rotation of the rotating shaft 102, so that the first mooring chain 2 and the rotating shaft 102 are reversed around the axis of the rotating shaft 102, so that the first mooring chain 2 is released from the rotating shaft 102, and the moored member to be connected is unmoored.

[0070] In some embodiments, the quick mooring device 100 further includes a length adjustment mechanism 6, the two ends of which are connected to the second mooring chain 3 and the base 101 respectively.
