Technical Field

[0001] This utility model relates to the field of lifting systems, and more particularly to a digital X-ray tube lifting system. Background Technology

[0002] In the current marine construction environment, limited space and the inability to meet the conditions for cross-operation among vessels have become constraints on improving the efficiency of marine construction. Specialized equipment for digital radiographic inspection systems with self-protection against radiation has improved the efficiency, on-site operability, and practicality of clamping and lifting the pipeline body during DR digital radiographic inspection of circumferential welds of subsea pipelines. The lifting system allows for remote control of the X-ray equipment's position, thereby protecting the safety of personnel. Existing digital radiographic inspection systems suffer from cumbersome operation, poor adaptability, and low efficiency when clamping and lifting subsea pipelines.

[0003] When clamping pipes, there are problems such as complicated disassembly and assembly steps, and inability to adapt to the clamping requirements of different pipe diameters. In view of this, a digital X-ray tube lifting system is provided. Utility Model Content

[0004] The main purpose of this invention is to provide a digital X-ray tube lifting system to solve the problem in related technologies that the disassembly and assembly steps are complicated when clamping pipes and cannot adapt to the clamping requirements of different pipe diameters.

[0005] To achieve the above objectives, according to one aspect of the present invention, a digital X-ray tube lifting system is provided, including a support part, two of which are symmetrically arranged, and further including: two positioning parts, which are symmetrically fixedly installed on the upper end of the support part, and the positioning parts are used to position and clamp pipes of different diameters; and a lifting part, which is fixedly installed on the upper end of the positioning parts, and the lifting part is used to adjust the position of the positioning parts.

[0006] Furthermore, the positioning part includes a centering outer rail, which is a ring structure.

[0007] Furthermore, an opening and closing rotating shaft is fixedly installed on the upper end of the outer arc wall of the centering outer rail, and two magnetic blocks are symmetrically fixedly installed near the lower end of the outer arc wall of the centering outer rail.

[0008] Furthermore, several mounting grooves are provided on the inner arc wall of the centering outer rail, and positioning support devices are fixedly installed in the mounting grooves.

[0009] Furthermore, the support part includes two support brackets. The support brackets are fixedly installed on the side wall of the centering outer rail near the lower end. A fixed connecting bracket is fixedly installed on the side wall of the support bracket near the lower surface edge. The fixed connecting bracket connects the support brackets on both sides.

[0010] Furthermore, the lifting section includes several power transmission brackets, which are fixedly installed on the side wall of the centering outer rail near the upper end. A mounting bracket is fixedly installed on the side wall of the power transmission bracket near the upper edge, and the mounting bracket connects the power transmission brackets on both sides.

[0011] Furthermore, the lifting section also includes a lifting beam, on which two connecting rods are symmetrically and rotatably mounted, with the other end of each connecting rod rotatably mounted in an adjustment hole.

[0012] Furthermore, a locking screw hole is provided through the side wall of the lifting beam, and a lifting locking bolt is installed in the internal thread of the locking screw hole.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the lifting beam of the lifting unit is fixedly connected to the overhead crane via lifting locking bolts. The magnetic block below the centering outer rail is opened, and the centering outer rail automatically opens during the lifting process. A power transmission bracket is fixedly installed on the side wall of the centering outer rail near the upper edge. The side wall of the power transmission bracket has several adjustment holes. One end of the connecting rod is rotated and installed in different adjustment holes to accommodate different pipe diameters. The detection system is moved above the pipe weld and lowered after the positioning part at one end of the lifting unit is positioned, so that the positioning support device contacts the pipe wall. The magnetic block is attracted by electromagnetic control, thereby locking the centering outer rail. The lifting beam applies external force to lift, and the power transmission bracket moves vertically through the connecting rod, which drives the opening and closing shaft to rotate, thereby controlling the opening and closing of the centering outer rail. When the lifting beam is subjected to an upward tension, the centering outer rail opens in a specific direction to clamp and assemble the pipe body. When the lifting beam is not under force, the device itself and the gravity of the centering outer rail clamp the subsea pipeline body. The positioning support device can adjust the support force and clamping force of the pipe body according to the needs of the site to meet the clamping requirements of different subsea pipeline diameters. After clamping, the centering outer rail is locked and fixed by magnetic blocks. After the inspection is completed, the current switch is turned off to eliminate the magnetic attraction force, so that the centering outer rail can be removed. Attached Figure Description

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] This embodiment provides a digital X-ray tube lifting system, including a support part 2, which has two symmetrically arranged parts, and also includes: two positioning parts 1, which are symmetrically fixedly installed on the upper end of the support part 2, and the positioning parts 1 are used to position and clamp pipes of different diameters; and a lifting part 3, which is fixedly installed on the upper end of the positioning parts 1, and the lifting part 3 adjusts the position of the positioning parts 1.

[0025] like Figure 1 , Figure 2 As shown, the positioning part 1 includes a centering outer rail 11, which is a ring structure;

[0026] like Figure 2 , Figure 3 As shown, an opening and closing rotating shaft 112 is fixedly installed on the upper end of the outer arc wall of the centering outer rail 11. Two magnetic blocks 13 are symmetrically fixedly installed near the lower end of the outer arc wall of the centering outer rail 11. Before clamping, the magnetic blocks 13 below the centering outer rail 11 are opened. During the lifting process, the centering outer rail 11 opens automatically. After clamping, the centering outer rail 11 is locked and fixed by the magnetic blocks 13. After the test is completed, the current switch is turned off to eliminate the magnetic attraction force, so that the centering outer rail 11 can be removed.

[0027] like Figure 3 As shown, a number of installation grooves 111 are provided on the inner arc wall of the centering outer rail 11. A positioning support device 12 is fixedly installed in the installation groove 111. The positioning support device 12 can adjust the size of the support force and clamping force of the pipe body according to the site requirements to meet the clamping requirements of different submarine pipeline diameters.

[0028] like Figure 1As shown, the support part 2 includes two support brackets 21. The support brackets 21 are fixedly installed on the side wall of the centering outer rail 11 near the lower end. A fixed connecting bracket 22 is fixedly installed on the side wall of the support bracket 21 near the lower surface edge. The fixed connecting bracket 22 connects the support brackets 21 on both sides. The lateral movement of the submarine pipeline is locked by the fixed connecting bracket 22 to ensure the stable operation of the overall system mechanism during the DR digital X-ray inspection process.

[0029] like Figure 4 As shown, the lifting part 3 includes several power transmission brackets 31. The power transmission brackets 31 are fixedly installed on the side wall of the centering outer rail 11 near the upper end. The side wall of the power transmission bracket 31 is fixedly installed with a mounting bracket 311 near the upper edge. The mounting bracket 311 connects the power transmission brackets 31 on both sides. The power transmission brackets 31 are driven to move vertically through the connecting rod 32, which drives the opening and closing shaft 112 to rotate, thereby controlling the opening and closing of the centering outer rail 11.

[0030] like Figure 4 As shown, the lifting part 3 also includes a lifting beam 33. Two connecting rods 32 are symmetrically and rotatably installed on the side wall of the lifting beam 33. The other end of the connecting rod 32 is rotatably installed in the adjustment hole 312. By rotatably installing one end of the connecting rod 32 in different adjustment holes 312, it can adapt to different pipe diameters.

[0031] like Figure 4 As shown, a locking screw hole is provided through the side wall of the lifting beam 33, and a lifting locking bolt 331 is installed in the internal thread of the locking screw hole. The lifting beam 33 is fixedly connected to the overhead crane through the lifting locking bolt 331.

[0032] In practical use, the lifting beam 33 of the lifting part 3 is fixedly connected to the overhead crane via the lifting locking bolt 331. The magnetic block 13 below the centering outer rail 11 is opened, and the centering outer rail 11 automatically opens during the lifting process. A power transmission bracket 31 is fixedly installed on the side wall of the centering outer rail 11 near the upper edge. The side wall of the power transmission bracket 31 has several adjustment holes 312. One end of the connecting rod 32 is rotated and installed in different adjustment holes 312 to adapt to different pipe diameters. The detection system is moved to the position of the positioning part 1 at one end of the lifting part 3 and then lowered so that the positioning support device 12 contacts the pipe wall. The magnetic block 13 is attracted by electromagnetic control to lock the centering outer rail 11. The lifting beam 33 applies external force to lift, and the power transmission bracket 31 moves vertically through the connecting rod 32, which drives the opening and closing shaft 112 to rotate, thereby controlling the opening and closing of the centering outer rail 11. When the lifting beam 33 is subjected to an upward pulling force, the centering outer rail 11 opens in a specific direction to clamp and assemble the pipe body in a specific direction. When the lifting beam 33 is not under force, the device itself and the gravity of the centering outer rail 11 clamp the submarine pipeline body. The positioning support device 12 can adjust the magnitude of the support force and clamping force of the pipe body according to the needs of the site to meet the clamping requirements of different submarine pipeline diameters. After clamping, the centering outer rail 11 is locked and fixed by the magnetic block 13. After the test is completed, the current switch is turned off to eliminate the magnetic attraction force so that the centering outer rail 11 can be removed.
