DETAILED DESCRIPTION
[0018] The specific implementation methods of the utility model are further explained in detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the utility model.
[0019] like Figure 1-5As shown, the utility model provides a vertical hanging device for a bottom-covered pipe segment, comprising a sliding frame 1, a center of gravity adjusting mechanism 3, a clamping plate 5 and an opening and closing mechanism 4. A fixed seat 2 is provided on the top of the sliding frame 1. The center of gravity adjusting mechanism 3 is arranged on the fixed seat 2 and is used to adjust the position of a suspension arm 32 on the fixed seat 2. Two clamping plates 5 are provided and are located on both sides of the sliding frame 1. The opening and closing mechanism 4 is arranged in the sliding frame 1 and controls the two clamping plates 5 to close or open at the same time so that the pipe segment is clamped or loosened.
[0020] It should be noted that the center of gravity adjustment mechanism 3 includes a moving seat 31 and an adjusting cylinder 33. The moving seat 31 is slidably connected to the slide rails on both sides of the fixed seat 2. The boom 32 is arranged on the moving seat 31. The cylinder body of the adjusting cylinder 33 is connected to the support 1 34 on the fixed seat 2, and the piston rod end of the adjusting cylinder 33 is connected to the support 2 35 on the side of the moving seat 31.
[0021] In addition, the splint 5 includes an outer arc hook leg 51, an inner arc hook leg 54 and a support plate 55. The two outer arc hook legs 51 are connected by a plurality of connecting plates 52. A mounting frame 53 is also provided between the upper ends of the two outer arc hook legs 51. The side of each outer arc hook leg 51 is provided with an inner arc hook leg 54 slidably connected to the sliding frame 1. The support plate 55 is provided at the lower end of the outer arc hook leg 51.
[0022] In addition, the support plate 55 includes a bottom plate 551 and a side plate 553. The bottom plate 551 is connected to the outer arc hook leg 51 and has a bottom pad 552 thereon. The side plate 553 is vertically arranged on the bottom plate 551 and connected to the outer arc hook leg 51. The side of the side plate 553 has a side pad 554 thereon.
[0023] It is worth noting that the opening and closing mechanism 4 includes a rotating shaft 41, a gear 42, a rack 43 and an opening and closing cylinder 44. The rotating shaft 41 is rotatably connected to the sliding frame 1 and is equipped with a gear 42. The gear 42 is meshed with the rack 43 on the inner arc hook leg 54. The cylinder body of the opening and closing cylinder 44 is connected to a support three 45 on one of the mounting frames 53, and the piston rod of the opening and closing cylinder 44 is connected to a support four 46 on another mounting frame 53. Through an opening and closing cylinder 44, two splints 5 can be driven to open and close at the same time.
[0024] Specific implementation and principle:
[0025] In actual application, the hook of the lifting device is hooked on the lifting arm 32 on the movable seat 31 of the lifting device. When the pipe segment needs to be lifted, the lifting device is moved to the pipe segment so that the bottom plate 551 of the support plate 55 is located at the bottom of the pipe segment. Then, the piston rod of the opening and closing oil cylinder 44 moves, and the clamping plates 5 on both sides of the sliding frame 1 are driven to approach the pipe segment through the gear 42 and the rack 43 to clamp and fix the pipe segment. Then, the lifting device transfers the pipe segment to the destination.
[0026] When the center of gravity of the sling needs to be adjusted, the movable seat 31 is driven to move to a suitable position on the fixed seat 2 by adjusting the movement of the piston rod of the oil cylinder 33 .
[0027] In summary, the utility model drives the two clamping plates 5 to close or open simultaneously through the opening and closing cylinder 44, gear 42 and rack 43 of the opening and closing mechanism 4 so that the pipe segments are clamped or loosened. The overall structure is relatively simple, saving manufacturing costs. In addition, the center of gravity during lifting is adjusted through the adjusting cylinder 33 and the moving seat 31 of the center of gravity adjusting mechanism 3.
[0028] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
