[0015] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0016] In order to further understand the content of the present application, the present application will be described in detail in combination with the drawings.

[0017] In combination with the drawings, Figs. 1-3 The present application discloses a skin raft automatic hooking and unhooking device, which comprises a lower platform and an upper platform, and a guide rail 1 extending from the lower platform to the upper platform, a lower skin raft frame 2 and an upper skin raft frame 3 are arranged at the lower platform and the upper platform respectively, and the lower skin raft frame 2 and the upper skin raft frame 3 are both located below the guide rail 1,

[0018] 2、The guide rail 1 is provided with a transmission chain driven by an external motor, and a plurality of hook assemblies 4 are arranged on the transmission chain, which act on the skin raft 5 placed on the lower skin raft frame 2 to transport the skin raft 5 from the lower platform to the upper platform. The lower skin raft frame 2 and the upper skin raft frame 3 are both provided with a plurality of conveying rollers, which can make the skin raft 5 slide on the lower skin raft frame 2 and the upper skin raft frame 3.

[0019] In order to complete the hooking and unhooking operation of the skin raft 5, the hook assembly 4 needs to be designed. The hook assembly 4 comprises a swing arm composed of two branch arms 6, which are fixed by rivets 7 and each provided with a notch 8 at the head end. The two notches 8 are oppositely arranged to make the branch arms 6 fit on the transmission chain. Such structure can make the swing arm rotate with the transmission chain, and the swing arm will always be downward due to its own gravity. The user only needs to oppositely arrange the two notches 8 to make the branch arms 6 fit on the transmission chain and then fix them by the rivets 7.

[0020] The head end of the swing arm is connected to the transmission chain, and the tail end is connected to one end of a connecting plate 9 through a pin shaft. The other end of the connecting plate 9 is connected to a spherical hook 10 through a ball head screw. The spherical hook 10 cooperates with a hook seat 11 at the head end of the skin raft 5. The hook seat comprises a U-shaped limiting part and a base integrated therewith. The distance between the two sides of the U-shaped limiting part is smaller than the diameter of the spherical hook 10, and the distance between the two sides of the base is greater than the diameter of the spherical hook 10. Since the distance between the two sides of the base is greater than the diameter of the spherical hook 10, the spherical hook 10 enters the base and then enters the U-shaped limiting part. When the spherical hook 10 is lifted, the U-shaped limiting part limits the spherical hook 10, so that the skin raft 5 can be lifted.

[0021] The guide rail 1 is divided into a hooking section, a lifting and conveying section and an unhooking section. The guide rail 1 at the hooking section completes the hooking operation of the hook assembly 4 on the skin raft 5. The guide rail 1 at the lifting and conveying section completes the lifting and conveying operation of the skin raft 5. The guide rail 1 at the unhooking section completes the unhooking operation of the hook assembly 4 on the skin raft 5. The guide rail 1 at the hooking section is downwardly inclined along the movement direction of the skin raft 5. The lower skin raft frame 2 is upwardly inclined along the movement direction of the skin raft 5. The hook assembly 5 gradually moves downward until it hooks with the hook seat 11. The guide rail 1 at the unhooking section is downwardly inclined along the movement direction of the skin raft 5. The upper skin raft frame 3 is downwardly inclined along the movement direction of the skin raft 5. When the bottom of the skin raft 5 falls to the upper skin raft frame 3, the sliding speed of the skin raft 5 due to its own gravity should be greater than the advancing speed of the hook assembly 4. Due to the gravity of the skin raft 5, the hook assembly 4 gradually separates from the hook seat 11 to realize the unhooking operation.

[0022] Working principle: the raft 5 is placed in the specified position of the lower raft frame 2, the external motor is started, the hook assembly 4 on the transmission chain is driven to slide on the guide rail 1, since the lower raft frame 2 is arranged upwardly inclined along the movement direction of the raft 5, the guide rail 1 at the upper hooking section is arranged downwardly inclined along the movement direction of the raft 5, then the hook assembly 4 will gradually approach the hook seat 11 at the raft 5, the spherical hook 10 in the hook assembly 4 enters the base first, and then enters the U-shaped limiting part, at this time the hook assembly 4 moves to the guide rail 1 at the lifting conveying section, since the U-shaped limiting part limits the spherical hook 10, the raft 5 moves along with the movement of the hook assembly 4, until reaching the guide rail 1 at the unhooking section, since the guide rail 1 at the unhooking section is arranged downwardly inclined along the movement direction of the raft 5, the upper raft frame 3 is arranged downwardly inclined along the movement direction of the raft 5, when the bottom of the raft 5 falls to the upper raft frame 3, since the self-gravity of the raft 5, the falling speed of the raft 5 is greater than the advancing speed of the hook assembly 4, then the hook assembly 4 gradually separates from the hook seat 11, the unhooking operation is realized, therefore the device only needs to start the motor, and the hooking and unhooking operations can be automatically realized.

[0023] It should be noted that the relational terms herein such as first and second and the like are used solely to distinguish one from another entity or action without necessarily requiring or implying that the entities or actions are in any way mutually exclusive or directional.

[0024] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
