[0009] In the above technical solution, further, the protection mechanism includes a fixed plate, which is fixedly connected to the bottom of the sliding plate. A sliding groove is provided on one side of the two fixed plates, and a sliding bar is slidably connected inside the two sliding grooves. One side of the two sliding bars is respectively fixedly connected to the No. 1 rack and the No. 2 rack.

[0010] In the above technical solution, further, a fixed plate is internally rotatably connected to a first gear and a second gear, the first gear is meshed with a first rack, the second gear is meshed with a second rack, and a motor is fixedly connected to one side of the fixed plate.

[0011] In the above technical solution, further, the first gear, the second gear and the output end of the motor are fixedly connected with bevel gears, and both sides of the bevel gear at the output end of the motor are respectively engaged with the bevel gears at the first gear and the second gear.

[0012] In the above technical solution, further, the clamping mechanism includes a fixed seat, the fixed seat is fixedly connected to the inside of the mounting plate, the diamond block is rotatably connected to the outside of the fixed seat, and a connecting block is fixedly connected above the fixed seat, and the connecting block is fixedly connected to the end of the chain.

As the No. 1 rack and the No. 2 rack continue to slide, when the bottom ends of the No. 1 rack and the No. 2 rack intersect, the aluminum tube can be protected. The support limit at the bottom prevents it from tilting. In addition, the staff can pull the limit rod through the handle along the direction of the outside of the sliding plate. After the limit rod is pulled, the spring will be squeezed and elastically compressed. After the limit rod is disengaged from the inside of the limit hole, the staff can pull the sliding plate and cause the sliding plate and the mounting plate to slide relative to each other. Because the two sliding plates are transmitted through the diamond blocks and the synchronization rods, when one sliding plate slides, the other sliding plate will slide at the same time, thereby adjusting the distance between the two sliding plates, so that this device can be used for aluminum tubes of different lengths.

[0020] When the two sliding plates 23 are adjusted to the desired distance, the staff can release the handle 26, and the spring 25 in the elastically contracted state will rebound. The rebound of the spring 25 will drive the limiting rod 24 to reset, and make one end of the limiting rod 24 re-engage the inner limit hole 27 corresponding to the front of the limiting rod 24, at this time, the limiting movement of the sliding plate 23 is completed.

[0021] Example 2 like Figure 1 - Figure 9The shown aluminum profile processing and lifting device comprises a protective mechanism 3 including a fixed plate 31, which is fixedly connected to the bottom of the sliding plate 23. A sliding groove 39 is provided on one side of the two fixed plates 31, and a sliding bar 38 is slidably connected inside the two sliding grooves 39. One side of the two sliding bars 38 is fixedly connected to the No. 1 rack 32 and the No. 2 rack 33 respectively. The interior of one fixed plate 31 is rotatably connected to the No. 1 gear 34 and the No. 2 gear 35. The No. 1 gear 34 is meshed with the No. 1 rack 32, and the No. 2 gear 35 is meshed with the No. 2 rack 33. One side of the fixed plate 31 is fixedly connected to a motor 37. The No. 1 gear 34, the No. 2 gear 35 and the output end of the motor 37 are all fixedly connected to a bevel gear 36. The two sides of the bevel gear 36 at the output end of the motor 37 are respectively meshed with the bevel gears 36 at the No. 1 gear 34 and the No. 2 gear 35.

[0022] When the first gear 34 and the second gear 35 rotate in opposite directions, the first rack 32 and the second rack 33 slide on one side of the two fixed plates 31 respectively, and the sliding directions are opposite. The sliding path is an arc shape. As the first rack 32 and the second rack 33 continue to slide, when the bottom ends of the first rack 32 and the second rack 33 intersect and partially overlap, the closure of the fixed plate 31 and the bottom of the aluminum tube is completed. At this time, the support and limit of the bottom of the aluminum tube are completed to prevent it from tilting.

[0023] Example 3 like Figure 1 - Figure 9 The shown device is an aluminum profile processing and lifting device, in which the clamping mechanism 4 includes a fixed seat 41, which is fixedly connected to the inside of the mounting plate 15, and a diamond block 21 is rotatably connected to the outside of the fixed seat 41. A connecting block 42 is fixedly connected above the fixed seat 41, and the connecting block 42 is fixedly connected to the end of the chain 14. A support rod 43 is rotatably connected below the fixed seat 41, and an L-shaped rod 44 is rotatably connected below the support rod 43. The two L-shaped rods 44 are rotatably connected, and a clamping plate 47 is fixedly connected below the L-shaped rod 44. A fixed rod 45 is rotatably connected between the two L-shaped rods 44, and a sliding rod 46 is fixedly connected above the fixed rod 45. The sliding rod 46 is slidably connected to the fixed seat 41.

[0024] In this embodiment, if the aluminum tube needs to be clamped, the staff can start the hydraulic cylinder 12 to lower the horizontal height of the mounting plate 15. When the bottom of the fixing rod 45 touches the tube wall of the aluminum tube, relative sliding will occur between the sliding rod 46 and the fixing seat 41. At this time, the angle between the two support rods 43 becomes larger. Then the staff can start the hydraulic cylinder 12 again to move the mounting plate 15 upward. During this process, since the fixing rod 45 loses contact with the tube wall of the aluminum tube, the angle between the two support rods 43 will decrease during the rising process of the mounting plate 15, so that the two clamping plates 47 complete the extrusion and clamping of the aluminum tube.

[0025] Working principle: If it is necessary to clamp the aluminum tube, the staff can start the hydraulic cylinder 12 and the horizontal height of the mounting plate 15 will drop. When the bottom of the fixing rod 45 touches the tube wall of the aluminum tube, the sliding rod 46 and the fixing seat 41 will slide relative to each other. At this time, the angle between the two support rods 43 becomes larger. Then the staff can start the hydraulic cylinder 12 again to move the mounting plate 15 upward. In this process, since the fixing rod 45 loses contact with the tube wall of the aluminum tube, the angle between the two support rods 43 will decrease during the rising process of the mounting plate 15, so that the two clamping plates 47 can complete the clamping of the aluminum tube. After the limit rod 24 is pulled, the spring 25 is squeezed and elastically compressed. After the limit rod 24 is disengaged from the inner part of the limit hole 27, the staff can pull the sliding plate 23 to make the sliding plate 23 and the mounting plate 15 slide relative to each other. Because the two sliding plates 23 are driven by the diamond block 21 and the synchronization rod 22, when one sliding plate 23 slides, the other sliding plate 23 slides at the same time, thereby adjusting the distance between the two sliding plates 23. The distance is adjusted. After the two sliding plates 23 are adjusted to the required distance, the staff can loosen the handle 26. At this time, the spring 25 in the elastic contraction state will rebound. The rebound of the spring 25 will drive the limit rod 24 to reset, and make one end of the limit rod 24 re-connected to the inner limit hole 27 corresponding to the front of the limit rod 24. At this time, the limit of the sliding plate 23 after movement is completed, so as to adapt to aluminum tubes of different lengths. If it is necessary to protect the bottom end of the aluminum tube to prevent the aluminum tube from tilting and falling, the staff can start the motor 37. The motor 37 starts After that, through the transmission of the bevel gear 36, the number one gear 34 and the number two gear 35 will rotate simultaneously, and the directions of rotation of the number one gear 34 and the number two gear 35 are opposite. When the number one gear 34 and the number two gear 35 rotate in two directions at the same time, the number one rack 32 and the number two rack 33 slide on one side of the two fixed plates 31 respectively, and the sliding path is an arc shape. As the number one rack 32 and the number two rack 33 continue to slide, when the bottom ends of the number one rack 32 and the number two rack 33 intersect, the support and limit of the bottom of the aluminum tube can be completed to prevent it from tilting.
