[0021] like Figure 1-3 As shown, the utility model proposes a tower-attached pipeline lifting lug installation device, including a lifting lug body 8, which is a cylinder 81 and is vertically fixed on the outer wall of the pipeline 1. A cross-shaped reinforcement plate 82 is fixed in the cylinder 81 of the lifting lug body 8, and the reinforcement plate 82 can significantly improve the structural strength of the lifting lug.

[0022] A clamping member 7 is detachably fixed on the outer wall of the lifting ear body 8. In this example, the clamping member 7 includes two arc-shaped clamping plates 71, the openings of the two clamping plates 71 are relatively clamped on the circumferential outer wall of the lifting ear body 8, and a fixing screw 72 is movably penetrated between the opening edges on the same side of the two clamping plates 71. The two clamping plates 71 are abutted and fixed by fixing nuts 73 threadedly sleeved on the fixing screw 72. The two arc-shaped clamping plates 71 clamp and fix the lifting ear body 8 firmly by tightening the fixing nuts 73 at both ends of the fixing screw 72. In this embodiment, the opening diameter of the clamping plates 71 is larger than the diameter of the lifting ear body 8, so that the arc-shaped clamping plates 71 can be installed and used to accommodate lifting ears of different diameters.

[0023] The first adjustment rod is fixedly connected to the middle of the corresponding clamping plate 71. The middle of the two clamping plates 71 is respectively fixed with a first adjustment rod perpendicular to the ear body 8, and a moving block 4 is adjustably mounted on the first adjustment rod along its length direction, and a second adjustment rod is perpendicular to the first adjustment rod and movably penetrates the moving block 4, and a first fixing member for fixing the second adjustment rod is provided on the moving block 4.

[0024] Specifically, the first adjustment rod is a first screw rod 6, the end of which is vertically fixed in the middle of the clamping plate 71, the moving block 4 is slidably mounted on the first screw rod 6, and the two ends of the moving block 4 are fixed by abutting against the adjusting nuts threaded on the first screw rod 6, so that the moving block 4 is effectively locked after the moving block 4 adjusts its position. The end angle of the second adjustment rod is adjustable and installed on the corresponding adsorption component. In this embodiment, the second adjustment rod is a slide rod 5, and the middle part of the slide rod 5 is movably mounted in the through hole on the moving block 4; the first fixing member includes a first bolt, which is installed on the side of the moving block 4 and its inner end extends into the through hole and abuts against the slide rod 5. According to the need to fix the adsorption component to a fixed position on the wall of the pipeline 1, the position of the moving block 4 on the first screw rod 6 is adjusted, and then the elongation length of the slide rod 5 is adjusted and locked by the first bolt, so that the device can adapt to the fixing requirements of different types of cylindrical hanging ears on the pipeline 1.

[0025] The adsorption assembly is adsorbed and fixed on the outer wall of the pipe 1. In this embodiment, the adsorption assembly includes a mounting block 2 and an electromagnet 3, and the electromagnet 3 is arranged at the bottom of the mounting block 2. The electromagnet 3 device that can be adsorbed on the steel pipe is a conventional application of the prior art, and its principle will not be repeated here.

[0026] The mounting block 2 is provided with a groove 21 , in which a rotating drum 51 is rotatably arranged via a rotating shaft, and the end of the slide rod 5 is fixedly connected to the outer wall of the rotating drum 51 in a direction perpendicular to the axis thereof. A first slide groove 22 is connected to the bottom of the groove 21, and a second slide groove 23 is vertically connected to the middle of the first slide groove 22. A first slider 91 is slidably provided in the first slide groove 22, and a second slider 92 is slidably provided in the second slide groove 23. A spring 93 is sleeved on the first slider 91, one end of the spring 93 is fixedly connected to the first slider 91, and the other end abuts against the opening of the first slide groove 22 close to the groove 21 side; the end of the second slider 92 extends into the first slide groove 22 and abuts against the first slider 91, and the vertical contact ends of the first slider 91 and the second slider 92 are provided with mutually matching inclined surfaces; one end of the second screw rod 94 threadedly penetrates the mounting block 2 and extends into the second slide groove 23 and is rotatably connected to the end of the second slider 92 away from the inclined surface, and the other end of the second screw rod 94 outside the mounting block 2 is fixedly provided with a rotating portion 941; the end of the first slider 91 extending into the groove 21 and the circumferential surface of the rotating cylinder 51 are both provided with mutually matching bite teeth 95. When the second screw rod 94 is screwed inwardly by the rotating part 941, the second slider 92 and the first slider 91 are slidably abutted through the inclined surface structure, so that the first slider 91 compresses the spring 93 and extends into the groove 21, and engages with the rotating cylinder 51 through the bite teeth 95, and locks and fixes the rotating cylinder 51, thereby achieving the fixation of the slide bar 5 after the angle adjustment. When the angle of the slide bar 5 needs to be adjusted, the second screw rod 94 is screwed in the opposite direction to drive the second slider 92 to slide into the second slide groove 23. Under the elastic force of the spring 93, the first slider 91 is retracted into the first slide groove 22, thereby releasing the locking of the bite teeth 95, so that the rotating cylinder 51 and the slider can be rotated to adjust the angle between the mounting block 2.

[0027] When using the utility model, first fix the clamping member 7 on the outer wall of the lifting ear body 8, adjust the position of the moving block 4 on the first screw rod 6 and the extension length of the slide bar 5 according to the installation position of the lifting ear body 8, change the angle between the slide bar 5 and the installation block 2, so that the electromagnet 3 of the adsorption assembly can be stably fixed on the outer wall of the pipe 1, and lock and fix the moving block 4 and the slide bar 5 by adjusting the nut and the first bolt respectively, thereby completing the positioning operation of the lifting ear body 8, and then use a welding machine to weld the lifting ear body 8 to the outer wall of the pipe 1. After the welding and installation of the lifting ear body 8 is completed, the clamping member 7, the adsorption assembly and other components can be removed.
