[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0039] Embodiment 1:

[0040] like Figures 1 to 14As shown in the figure, a cantilever type telescopic pipe shelf includes a shelf body 11. On both sides of the shelf body 11, safety frames 1 are provided. On one side of each safety frame 1, a runner 12 is provided. On the front and rear sides of the shelf body 11, telescopic frames 13 are provided, and pipes 14 are placed above the telescopic frames 13. On one side of the shelf body 11, two suspension ropes 2 are provided. The two suspension ropes 2 are arranged on a hoisting assembly. The bottom ends of the two suspension ropes 2 penetrate through mounting plates 21. At the bottom of each of the two mounting plates 21, three fixing plates 22 are provided. The three fixing plates 22 are respectively arranged at the bottom of the mounting plate 21. The suspension ropes 2 penetrate through the fixing plates 22. On both sides of each fixing plate 22, mounting brackets 28 are respectively provided. On the opposite sides of the mounting brackets 28, rotating assemblies are provided. On the rotating assemblies, a first limiting plate 271 and a second limiting plate 272 are respectively provided. The first limiting plate 271 and the second limiting plate 272 are used to position the pipes 14. In each telescopic frame 13, a plurality of first turning plates 3 and second turning plates 34 are provided. On each first turning plate 3 and second turning plate 34, a turning assembly is provided. The turning assembly is used to drive the first turning plate 3 and the second turning plate 34 to limit the pipes 14 placed on the telescopic frame 13. By lowering the first limiting plate 271 and the second limiting plate 272 so that the first limiting plate 271 and the second limiting plate 272 are located on both sides of the pipes 14, and straightening the suspension ropes 2 through the hoisting assembly, the first limiting plate 271 and the second limiting plate 272 can clamp and limit the pipes 14, thus lifting the pipes 14. By adjusting the hoisting assembly, the pipes 14 are slowly placed on the telescopic frames 13. At this time, the pipes 14 will press the first turning plates 3 and the second turning plates 34 to turn with the assistance of the turning assembly until the pipes 14 are completely located on the telescopic frames 13. At this time, the first turning plates 3 and the second turning plates 34 are in a V shape, so that the placed pipes 14 can be limited, thereby preventing the pipes 14 from moving.

[0041] As Figures 7 to 10 shown, in the specific implementation manner, the rotating assembly includes two rotating rods 27. The two rotating rods 27 are respectively arranged on the opposite side walls of four mounting brackets 28 in pairs. The two rotating rods 27 are symmetric with each other. At both ends of the two rotating rods 27, bearings 273 are provided. Each bearing 273 is respectively arranged on the mounting bracket 28. In this setting, the installation positions of the rotating rods 27 and the setting positions of the bearings 273 are determined, ensuring that the rotating rods 27 can rotate.

[0042] As Figures 1 to 10 shown, further, a first limiting plate 271 and a second limiting plate 272 are respectively arranged on the two rotating rods 27. The first limiting plate 271 and the second limiting plate 272 are symmetric with each other. In this setting, the positions of the first limiting plate 271 and the second limiting plate 272 and the connection relationship between the first limiting plate 271 and the second limiting plate 272 and the rotating rods 27 are determined.

[0043] AsFigures 7 to 10 As shown, further, a first cam 26 and a second cam 261 are respectively arranged on two rotating rods 27. The first cam 26 and the second cam 261 are symmetrical to each other, and sliding mechanisms are arranged on both the first cam 26 and the second cam 261. In this setting, the installation positions of the first cam 26 and the second cam 261, as well as the connection relationship between the first cam 26 and the second cam 261 and the rotating rod 27, are determined.

[0044] As Figures 7 to 10 shown, further, the sliding mechanism includes two moving chutes 262. The two moving chutes 262 are respectively opened on the first cam 26 and the second cam 261. The two moving chutes 262 are symmetrical to each other. A moving slider 263 is slidably arranged in the inner cavities of the two moving chutes 262. The two moving sliders 263 are symmetrical to each other. In this setting, it is ensured that because moving chutes 262 are opened on both the first cam 26 and the second cam 261, a moving slider 263 is slidably arranged on the moving chutes 262, and a swing arm 25 is arranged on the moving slider 263. Therefore, the first cam 26 and the second cam 261 can be pulled to rotate with the assistance of the rotating rod 27.

[0045] Embodiment 2:

[0046] Based on Embodiment 1, the difference from this embodiment is that: as Figures 7 to 11 shown, for a cantilever type pipe telescopic shelf, two symmetrical circular cylinders 24 are arranged at the bottom of each fixed plate 22. A circular moving plate 242 is slidably arranged in the inner cavity of each circular cylinder 24. A return spring 243 is arranged above each circular moving plate 242. The other end of each return spring 243 is arranged on the inner wall of the circular cylinder 24. A circular insertion rod 241 is arranged on one side wall of each circular moving plate 242 away from the return spring 243. Each circular insertion rod 241 passes through the circular cylinder 24 movably. A placing plate 23 is arranged at one end of each circular insertion rod 241 away from the circular moving plate 242 respectively, and a suspension rope 2 is arranged above the placing plate 23. In this setting, it is ensured that when the suspension rope 2 is slack, at this time the placing plate 23 will lose the pulling force. Therefore, the placing plate 23 will enable the circular moving plate 242 to move vertically downward under the elastic force of the return spring 243 arranged in the circular cylinder 24. When the circular moving plate 242 moves vertically downward, at this time it can make the circular insertion rod 241 move vertically downward. When the circular insertion rod 241 moves vertically downward, at this time it can drive the placing plate 23 to perform a slow reset.

[0047] As Figures 7 to 10As shown, in the specific implementation manner, two swing arms 25 are provided at the bottom of each placement plate 23. Each pair of swing arms 25 is symmetric with each other, and one end of each swing arm 25 away from the placement plate 23 is respectively arranged on the moving slider 263. In this setting, it is ensured that when the placement plate 23 resets, it can drive the first cam 26 and the second cam 261 to rotate in the reverse direction with the assistance of the rotating rod 27 through the swing arms 25. When the rotating rod 27 rotates in the reverse direction, it will drive the first limiting plate 271 and the second limiting plate 272 to reset, thereby losing the clamping and limiting of the pipe 14. At this time, the staff removes the first limiting plate 271 and the second limiting plate 272 from the pipe 14, and can take out the first limiting plate 271 and the second limiting plate 272 by controlling the lifting assembly to drive the lifting rope 2 to rise, so as to facilitate the next lifting of the pipe.

[0048] Embodiment 3:

[0049] Based on Embodiment 2, the difference from this embodiment is: As Figures 1 to 3 and Figure 12 and Figure 13 As shown, for a cantilever type telescopic pipe shelf, a rectangular notch 131 is penetrated and opened on each telescopic frame 13. A plurality of placement notches 132 are arranged at equal intervals on the opposite inner side walls of the inner cavity of each rectangular notch 131. Each pair of placement notches 132 is symmetric with each other. In this setting, the opening position of the rectangular notch 131 is determined.

[0050] As Figures 1 to 3 and Figures 12 to 14 As shown, in the specific implementation manner, the flipping assembly includes a plurality of rotating rods 32. Each pair of rotating rods 32 is respectively arranged on the side walls of the first flipping plate 3 and the second flipping plate 34. Each pair of rotating rods 32 is symmetric with each other. One end of each pair of rotating rods 32 in opposite directions is provided with a damping bearing 31. Each pair of the damping bearings 31 is respectively arranged on the inner wall of the placement notch 132. In this setting, it is ensured that the first flipping plate 3 and the second flipping plate 34 can be flipped.

[0051] As Figures 1 to 3 and Figures 12 to 14As shown in the figure, further, torsion springs 33 are provided on each damping bearing 31, the first turning plate 3, and the second turning plate 34. One end of each torsion spring 33 is provided on the damping bearing 31, and the other end is provided on the first turning plate 3 and the second turning plate 34. Each torsion spring 33 is sleeved on the rotating rod 32. In this setting, when the pipe 14 is placed between the first turning plate 3 and the second turning plate 34 provided on the telescopic frame 13, the pipe 14 will press down the first turning plate 3 and the second turning plate 34 under the action of gravity, and with the assistance of the rotating rod 32, they can rotate until the whole pipe 14 fits with the telescopic frame 13. At this time, the force pressing down the first turning plate 3 and the second turning plate 34 will be stopped. At this time, the first turning plate 3 and the second turning plate 34 are in a V shape, so that the placed pipe 14 can be limited on the telescopic frame 13, thereby reducing the situation of moving on the telescopic frame 13 to a certain extent.

[0052] The implementation principle of a cantilever type pipe telescopic shelf of the present invention is as follows:

[0053] First, the staff rotates the runner 12, and moves the telescopic frame 13 that needs to be moved out from the shelf body 11 through the runner 12 (the specific movement of the telescopic frame 13 out is the prior art). When the telescopic frame 13 is moved out, at this time, the staff controls the hoisting assembly to lower the lifting rope 2 to the ground. At this time, the staff places the first limiting plate 271 and the second limiting plate 272 provided at the bottom of the lifting rope 2 on both sides of the pipe 14 respectively;

[0054] When the first limiting plate 271, the second limiting plate 272, and the pipe 14 are placed, at this time, the staff controls the hoisting assembly to straighten the lifting rope 2. When the lifting rope 2 is straightened, it can drive the placing plate 23 to move vertically upward with the assistance of the circular insertion rod 241 and the circular cylinder 24. When the placing plate 23 moves vertically upward, it can pull the first cam 26 and the second cam 261 to rotate with the assistance of the rotating rod 27 and the bearing 273 (wherein, since moving chutes 262 are provided on both the first cam 26 and the second cam 261, and moving sliders 263 are slidably arranged on the moving chutes 262, and a swing arm 25 is provided on the moving slider 263, so that the first cam 26 and the second cam 261 can be pulled to rotate with the assistance of the rotating rod 27);

[0055] When the rotating rod 27 rotates, at this time, the rotating rod 27 can drive the first limiting plate 271 and the second limiting plate 272 to rotate. When the first limiting plate 271 and the second limiting plate 272 rotate, they can clamp and limit the side wall of the pipe 14 placed on the ground (at this time, the states of the first limiting plate 271 and the second limiting plate 272 are that the bottoms of both ends of the first limiting plate 271 and the second limiting plate 272 will approach each other);

[0056] At this time, the hoisting assembly can lift the pipe 14 and adjust the position of the pipe 14 through the hoisting assembly. When the pipe 14 is above the telescopic frame 13, then control the hoisting assembly to slowly lower the pipe 14 (the hoisting and lowering of the hoisting assembly and the like are all prior arts).

[0057] When the pipe 14 is lowered onto the telescopic frame 13, it means that the pipe 14 contacts between the first turning plate 3 and the second turning plate 34 provided on the telescopic frame 13 (when the pipe 14 is lowered between the first turning plate 3 and the second turning plate 34 provided on the telescopic frame 13, the pipe 14 will press down the first turning plate 3 under the action of gravity, and the second turning plate 34 can rotate with the assistance of the rotating rod 32 until the whole pipe 14 fits the telescopic frame 13. At this time, the force pressing down on the first turning plate 3 and the second turning plate 34 will be stopped. At this time, the first turning plate 3 and the second turning plate 34 are in a V shape, so the placed pipe 14 can be limited on the telescopic frame 13, thus reducing the movement on the telescopic frame 13 to a certain extent). At this time, continue to lower the lifting rope 2, and the lifting rope 2 will become slack. When the lifting rope 2 is slack, the placing plate 23 will lose the pulling force. Therefore, the placing plate 23 will make the circular moving plate 242 move vertically downward under the elastic force of the return spring 243 provided in the circular cylinder 24. When the circular moving plate 242 moves vertically downward, it can make the circular insertion rod 241 move vertically downward. When the circular insertion rod 241 moves vertically downward, it can drive the placing plate 23 to slowly reset.

[0058] When the placing plate 23 is reset, it can drive the first cam 26 and the second cam 261 to rotate in the reverse direction with the assistance of the rotating rod 27 through the swing arm 25. When the rotating rod 27 rotates in the reverse direction, it can drive the first limiting plate 271 and the second limiting plate 272 to reset, so as to lose the clamping limit on the pipe 14. At this time, the staff takes out the first limiting plate 271 and the second limiting plate 272 from the pipe 14, and can take out the first limiting plate 271 and the second limiting plate 272 by controlling the hoisting assembly to drive the lifting rope 2 to rise, so as to facilitate the hoisting of the pipe next time.
