DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0037] like Figures 1 to 4 As shown, an automatic cable tray stacking device according to an embodiment of the present invention includes a support frame 1, a first direction moving component 11 is installed at the top of the support frame 1, a second direction moving component 12 is installed below the first direction moving component 11, a cylinder 14 is installed below the second direction moving component 12, and a group of symmetrical clamping plates 3 are provided below the cylinder 14. A trolley 2 is provided inside the support frame 1, and a handrail 21 is fixed to one side of the top of the trolley 2;

[0038] Positioning slots 22 are provided on both sides of the cart 2, and insert blocks 135 are slidably connected to the bottom ends of both sides of the interior of the support frame 1, and the insert blocks 135 can be engaged with the positioning slots 22;

[0039] When half of the length of the trolley 2 is pushed into the interior of the support frame 1, the insert block 135 is engaged with the positioning groove 22;

[0040] After the cable tray is produced, it will need to be stacked. By stacking, multiple cable trays can be stacked together. This method can make the cable tray occupy a smaller volume during transportation and is more convenient for transportation. In order to save the physical strength of the staff during stacking, the stacking device will be used for operation. Before the operation, the support frame 1 will be installed in the position of use, and then the trolley 2 needs to be pushed. At this time, use your hand to hold the armrest 21 and then push it. The armrest 21 drives the trolley 2 to move. The trolley 2 moves by rolling on the ground through the wheels at the bottom. Then, the trolley 2 is pushed to one side of the support frame 1. When the trolley 2 is pushed into the interior of the support frame 1, the armrest 21 is stopped. Then the cable tray that needs to be stacked can be placed on the other side of the interior of the support frame 1, and then the first direction moving component 11 and the second direction moving component 12 are started to move. At this time, the first direction moving component 11 and the second direction moving component 12 will drive the splint 3 to move in the x-axis and y-axis directions. After the lifting of the lifting device 14, the lifting plate 3 is lifted and the lifting device 10 is lifted, and the lifting device 10 is lifted and the lower limit switch 10 is released, and the lifting device 10 is automatically reset.

[0041] When the trolley 2 is pushed into the interior of the support frame 1, in order to prevent the position of the trolley 2 from being offset during stacking, after the trolley 2 is pushed into the interior of the support frame 1, the insert block 135 will be stuck into the interior of the positioning groove 22. At this time, the trolley 2 is fixed inside the support frame 1, and the trolley 2 can remain fixed during stacking, thereby preventing the trolley 2 from moving during the stacking process and causing the cable tray to slip.

[0042] like Figures 1 to 4 As shown, the bottom end of the support frame 1 is rotatably connected to the rotating plate 13, and the inclined surface of the rotating plate 13 faces the direction of the cart 2. A first spring 136 is fixed to one end of the insert block 135, and the other end of the first spring 136 is fixedly connected to the support frame 1. A pull rope 137 runs through the interior of the first spring 136, and one end of the pull rope 137 is fixedly connected to the insert block 135;

[0043] When the rotating plate 13 rotates, it drives the pull rope 137, and the pull rope 137 pulls the insert block 135 into the interior of the support frame 1;

[0044] When the trolley 2 is pushed into the interior of the support frame 1, the wheels of the trolley 2 will press on the surface of the rotating plate 13. At this time, the rotating plate 13 is forced to rotate. When the rotating plate 13 rotates, it will drive the pull rope 137. The pull rope 137 pulls the plug 135 into the interior of the support frame 1. At this time, the first spring 136 is squeezed. When the wheels of the trolley 2 pass the rotating plate 13, the rotating plate 13 loses pressure. The elastic force of the first spring 136 pushes the plug 135. The plug 135 is pressed against the side of the trolley 2. When the positioning groove 22 moves to the position of the plug 135, the first spring 136 pushes the plug 135 to insert into the interior of the positioning groove 22. At this time, the trolley 2 can be positioned to prevent the trolley 2 from moving during the stacking process.

[0045] like Figures 1 to 4 As shown, a slide groove 131 is provided on both sides of the rotating plate 13, and a first lifting plate 133 is fixed to the bottom end of the pull rope 137. The first lifting plate 133 is slidably connected to the inside of the support frame 1. A sliding post 134 is fixed to the side of the first lifting plate 133 close to the rotating plate 13, and the sliding post 134 is slidably connected to the inside of the slide groove 131;

[0046] When the rotating plate 13 is pressed down by the wheel of the cart 2, the rotating plate 13 drives the sliding column 134 through the sliding groove 131, and the sliding column 134 drives the first lifting plate 133 to move downward. The first lifting plate 133 can pull the pull rope 137 downward. When the first spring 136 pushes the plug block 135 to extend from the inside of the support frame 1, the plug block 135 pulls the first lifting plate 133 up through the pull rope 137. The first lifting plate 133 drives the rotating plate 13 to rotate and reset through the sliding column 134, so that the rotating plate 13 can be automatically reset.

[0047] like Figures 1 to 4 As shown, one end of the rotating shaft of the rotating plate 13 passes through the interior of the supporting frame 1, and a pressing plate 132 is fixed to one end of the rotating shaft of the rotating plate 13;

[0048] After the top of the cart 2 is loaded, when the cart 2 needs to be pulled out from the inside of the support frame 1, it is necessary to first separate the insert block 135 from the positioning groove 22. At this time, press the pressure plate 132 downward, and the pressure plate 132 drives the rotating plate 13 to rotate downward, so that the pull rope 137 pulls the insert block 135 into the inside of the support frame 1. At this time, the insert block 135 is separated from the positioning groove 22, and then the cart 2 can be pulled out from the inside of the support frame 1, and then the cart 2 can be separated from the support frame 1, which can facilitate the separation of the cart 2 from the inside of the support frame 1.

[0049] like Figures 1 to 6As shown, a rotating wheel 33 is provided at the bottom end of the splint 3, and a connecting column 31 is rotatably connected to the top end of the splint 3. A second motor 32 is installed at the bottom end of the oil cylinder 14, and the end of the rotating shaft of the second motor 32 is fixedly connected to the connecting column 31. An image sensor 34 is installed in the middle of the bottom end of the connecting column 31.

[0050] Among them, the image sensor 34 captures an image and controls the first direction moving component 11, the second direction moving component 12, the oil cylinder 14 and the second motor 32 to move to the corresponding position and angle of the cable tray according to the image;

[0051] During use, the image sensor 34 is used to capture an image to determine the current position of the cable tray, and then the splint 3 is moved to the position of the cable tray. The second motor 32 is then used to drive the connecting column 31 to rotate so that the angle of the splint 3 is aligned with the angle of the cable tray. The oil cylinder 14 then drives the splint 3 down to the outside of the cable tray and clamps the cable tray through the rotating wheel 33. The second motor 32 is then used to correct the angle of the connecting column 31, so that the angle of the cable tray can be corrected and it is more stable when placed on the top of the cart 2.

[0052] like Figures 1 to 6 As shown, a sliding cavity 311 is provided inside the connecting column 31, and a second lifting plate 312 is slidably connected inside the sliding cavity 311. Both ends of the second lifting plate 312 are rotatably connected to connecting rods 313, and the bottom ends of the connecting rods 313 are rotatably connected to the top ends of the two clamping plates 3 respectively;

[0053] When the second lifting plate 312 descends, the connecting rod 313 drives the clamping plate 3 to rotate;

[0054] When the splint 3 needs to be clamped, the second lifting plate 312 moves downward inside the sliding cavity 311. At this time, the second lifting plate 312 drives the connecting rods 313 on both sides to push the splint 3 downward, so that the two splints 3 can rotate downward. At this time, the rotating wheel 33 at the end of the splint 3 can clamp the cable tray, which makes it easier for the splint 3 to clamp the cable tray.

[0055] like Figures 1 to 6 As shown, the interior of the connecting column 31 is rotatably connected to two threaded rods 314, which are threadedly connected to the second lifting plate 312. The bottom end of the threaded rod 314 is fixed with a transmission gear 315. The bottom end of the interior of the connecting column 31 is installed with a first motor 316. The end of the rotating shaft of the first motor 316 is fixed with an output gear, which is meshed with the transmission gear 315.

[0056] When the second lifting plate 312 needs to be lowered, the first motor 316 is started to drive the output gear at the end to rotate. At this time, the output gear drives the transmission gear 315 to rotate, and the transmission gear 315 drives the threaded rod 314 to rotate. When the threaded rod 314 rotates, it will drive the second lifting plate 312 to move downward. At this time, the second lifting plate 312 can control the clamping plate 3 to clamp the cable tray. When the clamping plate 3 needs to lower the cable tray, the first motor 316 rotates in the opposite direction to raise the second lifting plate 312. At this time, the clamping plate 3 is opened to lower the cable tray, which can facilitate automatic clamping of the cable tray.

[0057] like Figures 1 to 7 As shown, the outer portion of the rotating wheel 33 is rotatably connected to a support frame 331, a telescopic column 332 is fixed to the side of the support frame 331 close to the splint 3, the telescopic column 332 is inserted into the interior of the splint 3, and a second connecting plate 353 is fixed to the end of the telescopic column 332 away from the support frame 331. A pressure sensor 35 is installed inside the splint 3, and a first connecting plate 351 is fixed to the end of the pressure sensor 35. A third spring 352 is fixed between the first connecting plate 351 and the second connecting plate 353.

[0058] When the splint 3 clamps the cable tray, the wheel 33 will contact both sides of the cable tray. At this time, the wheel 33 is pushed in the opposite direction by the cable tray. The wheel 33 drives the support frame 331 to push the telescopic column 332. The telescopic column 332 squeezes the third spring 352 through the second connecting plate 353. The third spring 352 can buffer the clamping of the wheel 33. The third spring 352 pushes the pressure sensor 35 through the first connecting plate 351. When the pressure value of the pressure sensor 35 reaches the preset value, the splint 3 can clamp the cable tray. At this time, the cable tray can be transported to the top of the cart 2 by moving the first direction moving component 11, the second direction moving component 12 and the cylinder 14, so that it can be automatically judged whether the wheel 33 clamps the cable tray.

[0059] like Figures 6 to 8 As shown, push plates 334 are slidably connected to the interior of both sides of the support frame 331, and tooth columns 333 are fixed at both ends of the rotating wheel 33. The tooth columns 333 are rotatably connected to the interior of the support frame 331, and the teeth at the end of the push plate 334 can engage with the teeth on the outside of the tooth columns 333. The top and bottom ends of the push plate 334 are fixed with second springs 335, and the other end of the second spring 335 is fixedly connected to the support frame 331. The interior of the support frame 331 is rotatably connected to an eccentric block 336, and the outer side of the eccentric block 336 is tightly attached to one side of the push plate 334.

[0060] When the rotating wheel 33 needs to clamp the cable tray, the rotating wheel 33 needs to remain in a fixed state. At this time, the eccentric block 336 rotates the eccentric position to push the push plate 334 to be clamped on the outside of the tooth column 333, so that the tooth column 333 is fixed, thereby keeping the rotating wheel 33 in a fixed state.

[0061] When the splint 3 is opened to lower the cable bridge, the opening action of the splint 3 will affect the cable bridge already placed on the top of the trolley 2. Therefore, when the splint 3 is placed, the eccentric block 336 rotates to separate the eccentric position from the push plate 334. At this time, the second spring 335 pushes the push plate 334 to separate from the tooth column 333. At this time, the tooth column 333 loses its fixation, allowing the wheel 33 to rotate, and the cable bridge clamped by the wheel 33 can slide downward due to the rolling of the wheel 33. At this time, the splint 3 can lower the cable bridge at a higher place, preventing the splint 3 from opening and pushing down the cable bridge already placed on the top of the trolley 2.

[0062] like Figures 7 to 9 As shown, a transmission rod 337 is rotatably connected to the support frame 331. Both ends of the transmission rod 337 are fixedly connected to the eccentric block 336. A gear is fixed to the middle of the transmission rod 337. A third motor 338 is installed inside the support frame 331. An output gear is fixed to the end of the rotating shaft of the third motor 338. The output gear is meshed with the gear of the transmission rod 337.

[0063] When the eccentric block 336 needs to rotate, the third motor 338 is started to drive the transmission rod 337 to rotate through the output gear. The transmission rod 337 drives the two eccentric blocks 336 to rotate, and can simultaneously control the gear columns 333 on both sides to rotate or fix.
