[0105] By setting the rotating assembly 42, when the clamping arm 411 is needed to clamp the gun barrel 6, the second driving member 421 is started, and the output shaft of the second driving member 421 drives the worm 422 to rotate, the rotation of the worm 422 drives the turbine 424 to rotate, the rotation of the turbine 424 drives the main shaft 423 to rotate, the rotating main shaft 423 drives a rotating shaft 414 to rotate through the first universal joint 4251, the rotating main shaft 423 drives another rotating shaft 414 to rotate through the second universal joint 4252, the connecting shaft 4253 and the third universal joint 4254, the rotation of the rotating shaft 414 drives the rotating block 415 to rotate, and when the rotating block 415 abuts against the first bayonet 416, the rotating block 415 drives the clamping arm 411 to the direction of clamping the gun barrel 6. When the two clamping arms 411 rotate toward the direction approaching the gun barrel 6, the gun barrel 6 can be clamped; when the clamping arms 411 need to release the gun barrel 6, the output shaft of the second driving member 421 is controlled to rotate in the opposite direction, and the second driving member 421 drives the worm 422 to rotate, and finally the rotating shaft 414 rotates in the opposite direction, and the rotating shaft 414 drives the rotating block 415 to rotate in the direction away from the gun barrel 6. When the rotating block 415 abuts against the second bayonet 417, the rotating block 415 drives the clamping arms 411 to rotate in the direction away from the gun barrel 6 through the second bayonet 417, so that the two clamping arms 411 release the gun barrel 6, and the clamping arms 411 are separated from the gun barrel 6, and there is no need for people to manually separate the clamping arms 411 from the gun barrel 6.

[0106] After the clamping arm 411 releases the gun barrel 6 , the second driving member 421 drives the rotating shaft 414 to rotate, so that the limiting block is located between the first clamping pin 416 and the second clamping pin 417 .

[0107] In this embodiment, the turbine 424 is provided with a notch, and the rotating assembly 42 further includes a block 428 . The block 428 is disposed at the notch and connected to the inner wall of the housing 426 .

[0108] By setting the clamping block 428, the rotation angle of the turbine 424 can be limited to prevent the turbine 424 from rotating too much, causing the clamping force applied by the clamping arm 411 to be too large on the barrel 6, and to prevent the two clamping arms 411 from opening too much and closing too much.

[0109] In this embodiment, the docking mechanism 4 further includes two fixing arms 43 . The two fixing arms 43 are both connected to the guide rail 11 . The two fixing arms 43 and the two clamping assemblies 41 are alternately distributed along the circumference of the guide hole.

[0110] The fixing arms 43 are respectively arranged on both sides of the fixing plate 14 , are L-shaped, one right-angle side of the fixing arm 43 is connected to the fixing plate 14 , and the other right-angle side is arranged along the radial direction of the fixing plate 14 . The fixing arm 43 is connected to the guide rail 11 through the fixing plate 14 .

[0111] The other right-angled side of the fixing arm 43 close to the axis of the guide hole is an inclined surface, and the outer diameter of the other right-angled side of the fixing arm 43 decreases continuously in the direction away from the fixing plate 14 .

[0112] By setting the other right-angle side of the fixing arm 43 close to the axis of the guide hole as an inclined surface, it can be avoided that the fixing arm 43 is stuck on the end surface of the gun barrel 5 when the fixing arm 43 approaches the gun barrel 5.

[0113] The two clamping arms 411 and the two fixing arms 43 are alternately distributed along the circumference of the fixing plate 14 .

[0114] By setting two fixed arms 43, the two fixed arms 43 and the two clamping arms 411 surround a cylindrical area. When the fixed arms 43 and the clamping arms 411 are close to the gun barrel 5, the clamping arms 411 rotate, and the fixed arms 43 can provide stable support and guidance. After the clamping arms 411 are clamped on the gun barrel 5, under the action of the two fixed arms 43 and the two clamping arms 411, a stable connection between the fixed plate 14 and the gun barrel 5 is achieved. When the clamping arms 411 are separated from the gun barrel 5, the fixed arms 43 can provide support to avoid shaking during the separation of the clamping arms 411 and the gun barrel 5.

[0115] The specific working process of the present invention is as follows: when hoisting the shell 5, the steel cable of the hoist located at a high place is connected to the hook 325, and then the rope is released by the hoist to make the hoisting mechanism 3 move downward. When the clamping claw 311 abuts against the shell 5, the two clamping claws 311 of the clamping assembly 31 are opened along the outer wall of the shell 5. At this time, the fixing part 3132 slides downward along the guide of the guide groove 3134 until the two clamping claws 311 are sleeved on the shell 5, and then the rope is retracted by the hoist. At this time, the rope clamping assembly 31 moves upward, and the fixing part 3132 is opened along the guide groove 3134. The guide slides upward, and the two clamping claws 311 rotate towards each other under the action of gravity until the fixing portion 3132 abuts against the top inner wall of the guide groove 3134. At this time, the two clamping claws 311 clamp the shell 5 and the bottom of the clamping claws 311 is located at the lower side of the shell 5. At this time, the weight of the shell 5 cannot push the two clamping claws 311 to open, thereby realizing the lifting of the shell 5. The winch clamps and lifts the shell 5 through the clamping assembly 31. The clamping assembly 31 is set to automatically complete the clamping of the shell 5, and there is no need for people to manually drive the clamping assembly 1 to clamp the shell 5.

[0116] Then, the shell 5 is placed on the slide rail 12 of the guide rail 11, and the clamping assembly 31 holding the shell is slowly lowered by the winch until the shell 5 is located on the two slide rails 12, and then the clamping assembly 31 and the fixing assembly 32 are continued to be moved downward, so that the fixing part 3132 moves downward along the guide groove 3134, and then the two clamping claws 311 are manually opened, so that the clamping claws 311 release the shell 5, thereby realizing the separation of the clamping assembly 31 and the shell 5, and then the rope is passed through the fixing rings 17 on both sides of the guide rail 11, and the rope is hung on the two ends of the hook-shaped support plate 322, thereby realizing the connection between the support plate 322 and the guide rail 11, and then the clamping assembly 31, the fixing assembly 32, the shell 5 and the guide rail 11 are raised by the winch, and the shell 5 is loaded.

[0117] When loading the shell 5, the fixing assembly 1 with the shell 5 fixed thereon is lifted to a certain height by a winch, and then the two clamping arms 411 are aligned with the ends of the gun barrel 6, and the fixing plate 14 and the two clamping arms 411 are pushed toward the direction close to the gun barrel 6 by the fixing frame 11, and the inclined surface of the other end of the clamping arm 411 abuts against the gun barrel 6. As the clamping arm 411 approaches continuously, the other end of the clamping arm 411 rotates, and the rotating clamping arm 411 rotates the torsion spring 412. When the clamping groove of the clamping arm 411 is relative to the large diameter section of the polished end, the clamping arm 411 is clamped to the gun barrel 6 under the action of the torsion spring 412, and the clamping arm 411 is clamped to the gun barrel 6. After the two clamping arms 411 are clamped to the gun barrel 6, the fixing frame 11 and the gun barrel 6 are fixed.

[0118] In the process of pushing the shell 5 into the gun barrel 6, the first driving member 24 is started, and the first driving member 24 drives the first sprocket 21 to rotate around its own axis. The first sprocket 21 drives the chain 23 to move, and the chain 23 drives the second sprocket 22 to rotate. During the movement of the chain 23, the pusher block 15 is driven to move along the guide of the guide rail 11. Under the action of the pusher block 15, the shell 5 is slowly pushed into the gun barrel 6, thereby realizing the loading of the shell 5.

[0119] When the clamping arm 411 needs to be separated from the gun barrel 6, the second driving member 421 is started, and the output shaft of the second driving member 421 drives the worm 422 to rotate, and the rotation of the worm 422 drives the turbine 424 to rotate, and the rotation of the turbine 424 drives the main shaft 423 to rotate, and the rotating main shaft 423 drives a rotating shaft 414 to rotate through the first universal joint 4251, and the rotating main shaft 423 drives another rotating shaft 414 to rotate through the second universal joint 4252, the connecting shaft 4253 and the third universal joint 4254, and the rotation of the rotating shaft 414 drives the limit block 25 to rotate, and when the rotating block 415 abuts against the first bayonet 416, the rotating block 415 drives the clamping arm 411 to rotate in the direction of clamping the gun barrel 6. When the two clamping arms 411 rotate toward the direction approaching the gun barrel 6, the gun barrel 6 can be clamped; when the clamping arms 411 need to release the gun barrel 6, the output shaft of the control motor 31 is rotated in the opposite direction, and the motor 31 drives the worm 422 to rotate, and finally the rotating shaft 414 rotates in the opposite direction, and the rotating shaft 414 drives the rotating block 415 to rotate in the direction away from the gun barrel 6. When the rotating block 415 abuts against the second bayonet 417, the rotating block 415 drives the clamping arms 411 to rotate in the direction away from the gun barrel 6 through the second bayonet 417, so that the two clamping arms 411 release the gun barrel 6, and the clamping arms 411 are separated from the gun barrel 6, and there is no need for people to manually separate the clamping arms 411 from the gun barrel 6.

[0120] After the clamping arm 411 is separated from the gun barrel 6, the winch is controlled to release the rope, so that the supporting mechanism 1, the linear drive mechanism 2, the hoisting mechanism 3 and the docking mechanism 4 fall downward until the guide rail 11 is fixed to the ground or the supporting surface, and then the next loading is carried out.

[0121] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
