Description

Technical Field

[0001] The utility model relates to the technical field of hoisting devices, and more specifically, to a hoisting device used for pipeline installation. Background Art

[0002] At present, most of the liquid and gas transportation between cities has stopped with bottled transportation and switched to pipeline transportation. Compared with bottled transportation, pipeline transportation has less loss, greater safety, and cheaper transportation costs. Therefore, in most areas, whether it is municipal drainage construction, natural gas transmission or laying of tap water systems, laying pipeline systems is the first choice for construction workers.

[0003] When installing pipelines, operators often use lifting devices to lift heavier pipelines for easy transportation and installation. In actual use, although the existing lifting devices have basic lifting functions, they generally use fixed lifting devices to lift pipelines. Such fixed lifting devices cannot adjust the clamping position according to the length of the pipeline, which greatly limits its scope of use. Therefore, it is necessary to improve them.

The left and right ends of the rotating rod are hinged with connecting rods, and the number of the connecting rods is two. The other ends of the two connecting rods are respectively hinged to the upper surfaces of the two moving blocks. The rotation of the rotating rod causes the two connecting rods to drive the two moving blocks to move toward each other.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] 1. The utility model is provided with a fixed frame, a moving block, a round shaft, a rotating rod and a connecting rod.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 5 As shown, the utility model provides a lifting device for pipeline installation, comprising:

[0027] A top plate 1, with connecting frames 2 fixedly connected to the left and right sides of the lower surface of the top plate 1, and a fixing frame 3 fixedly connected to the bottom end of the inner surface of the connecting frame 2, and the number of the fixing frames 3 is two, and the positions of the two fixing frames 3 are symmetrical about the top plate 1;

[0028] A moving block 4, wherein outer surfaces of the front and rear sides of the moving block 4 are respectively movably connected to outer surfaces of the two fixing frames 3, and the number of the moving blocks 4 is two, and the two moving blocks 4 have the same size;

[0029] An adjustment mechanism, the adjustment mechanism is arranged on the upper side of the moving block 4;

[0030] Among them, the adjustment mechanism includes a driving motor 5, which is fixedly installed in the middle of the upper surface of the top plate 1. The bottom end of the driving motor 5 passes through the top plate 1 and extends to the bottom of the top plate 1. The other end of the output shaft of the driving motor 5 is fixedly sleeved with a round shaft 6. The outer surface of the round shaft 6 is fixedly sleeved with a rotating rod 7 located above the moving block 4. The left and right ends of the rotating rod 7 are hinged with connecting rods 8. There are two connecting rods 8. The other ends of the two connecting rods 8 are respectively hinged to the upper surfaces of the two moving blocks 4. The rotation of the rotating rod 7 causes the two connecting rods 8 to drive the two moving blocks 4 to move toward each other.

[0031] When the driving motor 5 is running, the circular shaft 6 will drive the rotating rod 7 and start to rotate together, and the rotation of the rotating rod 7 will drive the two connecting rods 8, causing the two connecting rods 8 to start to rotate. At the same time, the other ends of the two connecting rods 8 will respectively drive the two moving blocks 4, causing the two moving blocks 4 to move towards each other as a whole.

[0032] Among them, the outer surfaces of the two fixed frames 3 are both provided with limiting grooves 9, and the inner surfaces of the limiting grooves 9 are movably connected to limiting blocks 10. There are four limiting blocks 10, and the outer surfaces of the four limiting blocks 10 are respectively fixedly connected to the left and right sides of the outer surfaces of the two movable blocks 4.

[0033] Due to the design of the limiting groove 9 and the limiting block 10, the overall movement of the two moving blocks 4 is limited, thereby ensuring the stability of the two moving blocks 4 when they move toward each other as a whole.

[0034] The upper surface of the top plate 1 is fixedly connected with a hanging plate 11 , and the inner surface of the upper side of the hanging plate 11 is fixedly sleeved with a hanging bolt 12 .

[0035] The design of the hanging bolt 12 facilitates the operator to hoist the top plate 1 as a whole.

[0036] Among them, the bottom ends of the outer surfaces of the two moving blocks 4 are fixedly connected to the hollow box 13, and the right side of the inner surface of the hollow box 13 is movably connected to the fixed plate 17. The outer end of the fixed plate 17 penetrates the hollow box 13 and extends to the outside of the hollow box 13. The outer surface of the fixed plate 17 is movably connected to the limit plate 18, and the limit plate 18 is fixedly connected to the inner surface of the hollow box 13.

[0037] The fixing plate 17 can move under the limitation of the inner surface of the hollow box 13 .

[0038] The outer surface of the other end of the fixing plate 17 is hinged with a connecting plate 16 located inside the hollow box 13 . The number of the connecting plates 16 is eight, and the eight connecting plates 16 have the same size.

[0039] When the connecting plate 16 rotates, the fixing plate 17 moves driven by the connecting plate 16 .

[0040] The other ends of the eight connecting plates 16 are hinged with a movable plate 15 . There are two movable plates 15 . The positions of the two movable plates 15 are symmetrical with respect to the top plate 1 .

[0041] When the two moving plates 15 start to move toward each other, the eight connecting plates 16 will rotate.

[0042] Among them, the outer surfaces of the two moving plates 15 are fixedly connected with the hydraulic cylinder 14, and the other end of the hydraulic cylinder 14 passes through the hollow box 13 and the moving block 4 in sequence and extends to the outside of the moving block 4. The outer surface of the hydraulic cylinder 14 and the inner surface of the moving block 4 are fixedly sleeved.

[0043] When the hydraulic cylinder 14 operates, the moving plate 15 moves.

[0044] The working principle and use process of this utility model:

[0045] First, the operator starts the drive motor 5. As the drive motor 5 runs, the circular shaft 6 and the rotary rod 7 begin to rotate, and the rotation of the rotary rod 7 drives the two connecting rods 8, so that the two connecting rods 8 begin to rotate with the two ends of the rotary rod 7 as the axis. At the same time, the other ends of the two connecting rods 8 respectively drive the two moving blocks 4, so that the two moving blocks 4 as a whole begin to move away from each other under the common limit of the fixed frame 3 and the limit block 10. When the spacing between the two hollow boxes 13 as a whole is greater than the length of the pipeline, the operator puts the inner surface of the pipeline into the outer side of the two hollow boxes 13 and then starts the two hydraulic cylinders 14.

[0046] The operation of the two hydraulic cylinders 14 will cause the two movable plates 15 to start moving towards each other. During this process, the movement of the two movable plates 15 will drive the eight connecting plates 16 to rotate, and the other ends of the eight connecting plates 16 will drive the eight fixed plates 17, so that the eight fixed plates 17 start to move along the inner surface of the hollow box 13 toward the inner surface of the pipe. When the eight fixed plates 17 contact the inner surface of the pipe, the pipe will be fixed by the eight fixed plates 17, thereby ensuring the stability and safety of the pipe during lifting.

[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
