[0015] Preferably, the bottom of the pressure block is provided with a through hole, the through hole and the piercing knife are located on the same straight line and the diameter of the through hole is larger than the diameter of the piercing knife.

[0016] Preferably, the number of threaded rods is two, and the threads of the two threaded rods are opposite.

[0017] Preferably, a placement plate is fixedly provided on the top of the inner cavity of the second transport box, and an insertion hole is provided on the rear surface of the first transport box, with an insertion rod provided inside the insertion hole.

[0018] The fall protection device for vertical transport of compartment modules proposed in this invention has the following advantages:

[0019] 1. Through the set processing mechanism, the forward and reverse motors are started, and the insertion rod is pulled out from the insertion hole. The purpose of the insertion rod is to prevent the first rod from rotating when not in operation. The slot door is opened, and a bent item, such as a bent copper plate, is placed inside the first and second processing slots. The forward and reverse motors drive the worm gear to rotate, which in turn drives the worm wheel to rotate, which in turn drives the octagonal disc to rotate. When the octagonal disc rotates, the bottom of the vertical block moves along the edge of the octagonal disc. As the octagonal disc continues to rotate, the first rod rotates under the action of the vertical block. The rotation of the first rod drives the striking blocks at both ends to rotate. Then, the striking blocks repeatedly strike the pressure plate in the first processing slot, causing the pressure plate to descend. When the pressure plate descends, the first spring is compressed. The descent of the pressure plate helps to straighten the bent copper plate. Under the action of the first spring, the descending pressure plate can be reset inside the first processing slot. At the same time, the rotation of the octagonal disc drives the winding shaft to rotate, and then the rope is pulled down, carrying the pressure block. The second processing groove descends, and due to the weight of the pressure block itself, it can straighten the copper plate completely during descent. Some copper plates may need to be drilled before use. At this time, the cylinder is activated to drive the first step block to move. When the first step block moves, it will contact the second step block and force the second step block to descend. When the second step block descends, the support plate descends along the limit rod, and the second spring is stretched, which helps to provide support force for the second step block during descent. Then, the piercing knife at the bottom of the second step block extends out of the bottom of the pressure block through the through hole. The pressure block can first straighten the bent copper plate. After straightening, the piercing knife extends and the copper plate is drilled by the lifting and lowering of the piercing knife. When drilling is no longer needed, the cylinder retracts the first step block, and the piercing knife returns to the inside of the pressure block under the action of the second spring. When the forward and reverse motors reverse, the pull rope is wound up, which raises the pressure block inside the second processing groove. This allows the above operations to be achieved through the repeated lifting and lowering of the pressure block.

[0020] 2. Using the fixed mechanism, open the box door and place the straightened copper plate and other items into the first and second transport boxes respectively. Then, start the dual-axis motor to drive two threaded rods with opposite threads to rotate. When the two threaded rods rotate, the two first horizontal plates will move in opposite directions. The first horizontal plate moves along the slide rod towards the side of the first transport box. Since the round block on the second horizontal plate is located inside the inclined groove, the movement of the first horizontal plate will cause the second horizontal plate to descend on the support frame. When the second horizontal plate descends, it will drive the second pressing plate to descend through the vertical rod, pressing down some of the items. The movement of the first horizontal plate will also cause the first pressing plate to move, which helps to press down the items. In summary, by starting the dual-axis motor... The system enables the horizontal movement of the first clamping plate and the vertical movement of the second clamping plate. When the first clamping plate moves, it drives the connecting rod to move. When the connecting rod moves, it causes the first third clamping plate inside the second transport box to move horizontally. During this movement, the first second rod rotates, and then the first arc-shaped tooth rotates. Since the two arc-shaped teeth are meshed with each other, the rotation of the first arc-shaped tooth drives the rotation of the second arc-shaped tooth. The rotation of the second arc-shaped tooth drives the rotation of the second second rod, which causes the second third clamping plate to move horizontally. The two third clamping plates move in opposite directions, which helps to clamp and fix the items between the two third clamping plates. Attached Figure Description

[0030] Example 1

[0031] Key reference Figure 1-4 A fall protection device for vertical transport of cabin modules, comprising:

[0032] First transport container 1, used for transporting goods;

[0033] The second transport box 2 is fixed to both sides of the first transport box 1, and there are two of them.

[0034] The processing mechanism is located on the rear surface of the first transport box 1;

[0035] The fixing mechanism is located inside the first transport container 1 and the second transport container 2;

[0036] The processing mechanism includes a worm gear 3 rotatably connected to the rear surface of a first transport box 1, an octagonal disc 4 fixedly connected to the rear surface of the worm gear 3, a winding shaft 5 fixedly mounted on the rear surface of the octagonal disc 4, a forward and reverse motor 6 fixedly mounted on the rear surface of the first transport box 1, a worm gear 7 fixedly connected to the output end of the first forward and reverse motor 6, a first rod 8 rotatably connected to the rear surface of the first transport box 1, two vertical blocks 9 fixedly mounted on the outside of the first rod 8, striking blocks 10 fixedly mounted at both ends of the first rod 8, and a first processing groove 11 fixedly mounted on the rear surface of the first transport box 1. A first spring 12 is fixedly connected to the four corners of the bottom of the first processing groove 11. A pressure plate 13 is fixedly installed on the top of the first spring 12. The worm gear 3 meshes with the worm 7. A support block is fixedly installed on the rear surface of the first transport box 1. One end of the worm 7 is rotatably connected to the support block. A groove door is rotatably connected to the rear surface of the first processing groove 11. A box door is rotatably connected to the rear surfaces of the first transport box 1 and the second transport box 2. A through hole is provided at the bottom of the pressure block 17. The through hole and the piercing knife 24 are located on the same straight line and the diameter of the through hole is larger than the diameter of the piercing knife 24.

[0037] Specifically, the forward and reverse motor 6 drives the worm gear 7 to rotate, which in turn drives the worm wheel 3 to rotate, which in turn drives the octagonal disk 4 to rotate. When the octagonal disk 4 rotates, the bottom of the vertical block 9 moves along the edge of the octagonal disk 4. As the octagonal disk 4 continues to rotate and is driven by the vertical block 9, the first rod 8 rotates. The rotation of the first rod 8 drives the striking blocks 10 at both ends to rotate. Then, the striking blocks 10 repeatedly strike the pressure plate 13 in the first processing groove 11, causing the pressure plate 13 to descend. When the pressure plate 13 descends, the first spring 12 is compressed. The descent of the pressure plate 13 helps to straighten the bent copper plate. Under the action of the first spring 12, the descending pressure plate 13 can be reset inside the first processing groove 11.

[0038] The rear surface of the first transport box 1 is fixedly provided with a second processing groove 14 and a wire passage groove 15. The outside of the winding shaft 5 is wound with a pull rope 16. The pull rope 16 passes through the wire passage groove 15 and is fixedly connected to a pressure block 17 at the bottom. The inside of the pressure block 17 is fixedly provided with a limit rod 18 and a cylinder 19. The top of the inner cavity of the pressure block 17 is fixedly connected with a second spring 20. The output end of the cylinder 19 is fixedly connected with a first step block 21. The outside of the limit rod 18 is slidably connected with a support plate 22. The top of the support plate 22 is fixedly connected to the bottom of the second spring 20. A second step block 23 is fixedly connected to one side of the support plate 22. A piercing knife 24 is fixedly provided at the bottom of the second step block 23.

[0039] Specifically, when the octagonal disc 4 rotates, it drives the winding shaft 5 to rotate. Then, the pull rope 16 descends, taking the pressure block 17 down into the second processing groove 14. Because the pressure block 17 has its own weight, it can straighten the copper plate completely when it descends. Some copper plates may need to be drilled before use. At this time, the cylinder 19 is activated to drive the first step block 21 to move. When the first step block 21 moves, it will contact the second step block 23 and force the second step block 23 to descend. When the second step block 23 descends, the support plate 22 descends along the limit rod 18 and the second spring 20 is stretched, which helps to provide support force for the second step block 23 when it descends. Then, the piercing knife 24 at the bottom of the second step block 23 extends out of the bottom of the pressure block 17 through the through hole. The pressure block 17 can first straighten the bent copper plate. After straightening, the piercing knife 24 extends out and the copper plate is drilled by the lifting and lowering of the piercing knife 24.

[0040] Example 2

[0041] Key reference Figure 5-6 The fixing mechanism includes a dual-axis motor 25 fixedly installed on the rear wall of the inner cavity of the first transport box 1. Two slide rods 26 are fixedly installed inside the first transport box 1. A first horizontal plate 27 is slidably connected to the outside of the two slide rods 26. Threaded rods 28 are fixedly connected to both ends of the dual-axis motor 25. The threaded rods 28 pass through the first horizontal plate 27 and are rotatably connected to the first horizontal plate 27. An inclined groove 29 is provided on the front surface of the first horizontal plate 27. A support frame 30 is fixedly installed at the top of the inner cavity of the first transport box 1. A second horizontal plate 31 is slidably connected to the outside of the support frame 30. A round block 32 is fixedly installed on the rear surface of the second horizontal plate 31 and is located inside the inclined groove 29. A vertical rod 33 that passes through the bottom of the support frame 30 is fixedly installed at the bottom of the second horizontal plate 31. A first pressing plate 34 is fixedly installed on one side of the first horizontal plate 27. A second pressing plate 35 is fixedly installed at the bottom of the vertical rod 33. There are two threaded rods 28, and the threads of the two threaded rods 28 are opposite.

[0042] Specifically, the dual-axis motor 25 is then started to drive the two threaded rods 28 with opposite threads to rotate. When the two threaded rods 28 rotate, the two first horizontal plates 27 will move in opposite directions. The first horizontal plate 27 moves along the slide rod 26 to the side of the first transport box 1. Since the round block 32 on the second horizontal plate 31 is located inside the inclined groove 29, the first horizontal plate 27 will drive the second horizontal plate 31 to descend on the support frame 30 when it moves. When the second horizontal plate 31 descends, it drives the second pressing plate 35 to descend through the vertical rod 33 to press some items. When the first horizontal plate 27 moves, it drives the first pressing plate 34 to move, which helps to press the items. In summary, by starting the dual-axis motor 25, the horizontal movement of the first pressing plate 34 and the vertical movement of the second pressing plate 35 are achieved.

[0043] The bottom of the inner cavity of the second transport box 2 is horizontally slidably connected to a third pressing plate 36. The interior of the second transport box 2 is provided with a second rod 37. The top of the second rod 37 is rotatably connected to the inner cavity of the second transport box 2. An arc-shaped tooth 38 is fixedly provided on one side of the top of the second rod 37. The bottom of the second rod 37 is rotatably connected to one side of the third pressing plate 36. There are two of each of the third pressing plate 36, the second rod 37, and the arc-shaped tooth 38. The bottom of the first pressing plate 34 is fixedly connected to a connecting rod 39. One end of the connecting rod 39 passes through the interior of the second transport box 2 and is fixedly connected to the bottom of one of the second rods 37. The top of the inner cavity of the second transport box 2 is fixedly provided with a placement plate 40. The rear surface of the first transport box 1 is provided with an insertion hole, and an insertion rod 41 is provided inside the insertion hole.

[0044] Specifically, when the first clamping plate 34 moves, it will drive the connecting rod 39 to move. When the connecting rod 39 moves, it will cause the first third clamping plate 36 in the second transport box 2 to move horizontally. When it moves, the first second rod 37 will rotate, and then the first arc-shaped tooth 38 will rotate. Since the two arc-shaped teeth 38 are meshed with each other, when the first arc-shaped tooth 38 rotates, it will drive the second arc-shaped tooth 38 to rotate. The rotation of the second arc-shaped tooth 38 will drive the second second rod 37 to rotate. Through the rotation of the second second rod 37, the second third clamping plate 36 will move horizontally. The two third clamping plates 36 move in opposite directions, clamping and fixing the items between the two third clamping plates 36.

[0045] Working principle: The forward and reverse motor 6 is started, simultaneously pulling the insertion rod 41 out of the insertion hole. The purpose of the insertion rod 41 is to prevent the first rod 8 from rotating when not in operation. The slot door is opened, and a bent object, such as a bent copper plate, is placed inside the first processing slot 11 and the second processing slot 14. The forward and reverse motor 6 drives the worm gear 7 to rotate, which in turn drives the worm wheel 3 to rotate, which in turn drives the octagonal disc 4 to rotate. When the octagonal disc 4 rotates, the bottom of the vertical block 9 moves along the edge of the octagonal disc 4. As the octagonal disc 4 continues to rotate, and under the action of the vertical block 9, it drives the first rod 8 to rotate. The rotation of the first rod 8 drives the striking blocks 10 at both ends to rotate. Then, the striking blocks 10 repeatedly strike the pressure plate 13 in the first processing slot 11, causing the pressure plate 13 to descend. When the pressure plate 13 descends, the first... Spring 12 is compressed, and the descending pressure plate 13 straightens the bent copper plate. Under the action of the first spring 12, the descending pressure plate 13 can be reset inside the first processing groove 11. At the same time, when the octagonal disk 4 rotates, it drives the winding shaft 5 to rotate. Then, the pull rope 16 descends, taking the pressure block 17 down into the second processing groove 14. Because the pressure block 17 itself has weight, it can completely straighten the copper plate when it descends. Some copper plates may need to be drilled before use. At this time, the cylinder 19 is activated to drive the first step block 21 to move. When the first step block 21 moves, it will contact the second step block 23 and force the second step block 23 to descend. When the second step block 23 descends, the support plate 22 descends along the limit rod 18, and then the second spring 20 is stretched. The second step 23 provides support for descent. The piercing blade 24 at the bottom of the second step 23 extends through the through hole to the bottom of the pressure block 17. The pressure block 17 can first straighten the bent copper plate. After straightening, the piercing blade 24 extends and drills holes in the copper plate through its lifting and lowering motion. When drilling is no longer needed, the cylinder 19 retracts the first step 21, and the piercing blade 24 resets under the action of the second spring 20, returning to the inside of the pressure block 17. When the forward and reverse motor 6 reverses, it winds up the pull rope 16, raising the pressure block 17 inside the second processing groove 14. The above operations are achieved through the repeated lifting and lowering motion of the pressure block 17. After processing is complete, the box door is opened, and the straightened copper plate and other items are placed into the first transport box 1 and the second transport box 2, respectively. Inside, the dual-axis motor 25 is activated, driving two threaded rods 28 with opposite threads to rotate. The rotation of the two threaded rods 28 causes the two first horizontal plates 27 to move in opposite directions. The first horizontal plate 27 moves along the slide rod 26 towards the side of the first transport box 1. Since the round block 32 on the second horizontal plate 31 is located inside the inclined groove 29, the movement of the first horizontal plate 27 causes the second horizontal plate 31 to descend on the support frame 30. When the second horizontal plate 31 descends, it drives the second pressing plate 35 to descend via the vertical rod 33, pressing down on some items. When the first horizontal plate 27 moves, it drives the first pressing plate 34 to move, pressing down on the items. In summary, by activating the dual-axis motor 25, the horizontal movement of the first pressing plate 34 and the vertical movement of the second pressing plate 35 are achieved.When the first clamping plate 34 moves, it drives the connecting rod 39 to move. The movement of the connecting rod 39 causes the first third clamping plate 36 inside the second transport box 2 to move horizontally. This movement causes the first second rod 37 to rotate, and then the first arc-shaped tooth 38 to rotate. Since the two arc-shaped teeth 38 are meshed, the rotation of the first arc-shaped tooth 38 drives the second arc-shaped tooth 38 to rotate. The rotation of the second arc-shaped tooth 38 drives the second second rod 37 to rotate. This rotation of the second second rod 37 causes the second third clamping plate 36 to move horizontally. The two third clamping plates 36 move in opposite directions, clamping and securing the item between them. Once secured, the item is effectively prevented from falling.

Under the action of the first spring (12), the dropped pressure plate (13) can be reset inside the first processing groove (11). When the octagonal plate (4) rotates, it drives the winding shaft (5) to rotate. Then the rope (16) descends, carrying the pressure block (17) down into the second processing groove (14). Because the pressure block (17) itself has weight, it can straighten the bent copper plate when it descends. The bent copper plate is straightened by the processing mechanism. The straightened copper plate and other items are placed into the first and second transport boxes respectively. The items are clamped and fixed by the set fixing mechanism, which effectively prevents the items from falling after they are fixed.
