Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of positioning tooling, and in particular relates to a rapid positioning tooling used for inverted installation and lifting of industrial cylinder structures. Background Art
[0002] Industrial cylinders used in special environments, such as discharge towers, have small installation sites and no assembly sites on site, so the traditional installation method of assembling first and then hoisting cannot be used. Therefore, the chain hoisting and inverted installation method is used for pipeline installation. During the construction process, the discharge tower inverted welded pipes are lifted from bottom to top and chained section by section. Each discharge tower column welded pipe is composed of several sections of standard section welded pipes. The positioning and docking of standard sections are difficult, time-consuming and labor-intensive. The welded pipes are lifted and installed according to the standard sections. The traditional discharge tower construction requires welding discs to hang the standard sections with hooks for reverse lifting. This method has the problem that the chain hook is difficult to position during the chain hoisting process, and the docking accuracy of the tower standard section is low, which will damage the tower body strength. Therefore, it is necessary to propose improvements. Utility Model Content
[0003] The technical problem solved by the utility model is to provide a rapid positioning tool for the inverted lifting of industrial cylinder structures. The utility model aims to solve the problems of difficult positioning of the chain hook and low docking accuracy of the tower body standard sections during the inverted chain lifting of the industrial cylinder structure by designing a positioning and lifting auxiliary tool with simple structure, convenient installation, safety and reliability. It facilitates the rapid positioning and lifting of the blast furnace cylinder during the inverted construction of the industrial cylinder structure, improves the docking and installation accuracy, and speeds up the lifting efficiency.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] The quick positioning tool used for inverted lifting of industrial cylinder structures includes a quick-install positioning plate, a standard section positioning ring, a positioning wedge and an L-shaped connector. The quick-install positioning plate is used to be fixed on the standard section pipe body to be lifted. The quick-install positioning plate is symmetrically connected with L-shaped connectors on both sides. The lower parts of the two L-shaped connectors are connected with standard section positioning rings. The standard section positioning rings are tightly sleeved on the butt joints of two standard section pipes. There are multiple positioning wedges, and the positioning wedges are evenly inserted into the inner side of the standard section positioning ring to achieve alignment and positioning of the upper and lower standard sections.
[0006] To further limit the above scheme, the quick-release positioning disk is an annular structure composed of two half positioning disks, and positioning disk connecting seats are provided on the outer sides of both end heads of the half positioning disks. The positioning disk connecting seats at the splicing ends of the two half positioning disks are fixedly connected by positioning disk closing mouth bolts.
[0007] As a further limitation of the above solution, lifting ears are symmetrically provided on the outside of both sides of the quick-release positioning plate.
[0008] To further limit the above scheme, the standard section positioning ring is an annular structure formed by splicing two half positioning rings, and positioning ring connecting seats are provided on the outer sides of both ends of the half positioning rings. The positioning ring connecting seats at the splicing ends of the two half positioning rings are fixedly connected by positioning ring fixing bolts.
[0009] As a further limitation of the above solution, the L-shaped connector is an L-shaped connecting rod structure with a retractable length.
[0010] To further limit the above scheme, an upper connecting seat is provided at the corresponding position of the quick-release positioning plate, and the hole at the upper end of the L-shaped connector is connected to the hole on the upper connecting seat through an upper connecting pin; a lower connecting seat is provided at the corresponding position of the standard section positioning ring, and the hole at the lower end of the L-shaped connector is connected to the hole of the lower connecting seat through a lower connecting pin.
[0011] The advantages of this utility model compared with the prior art:

[0013] 2. This solution uses an annular fastening ring for the lifting device during the lifting process, and uses high-strength expansion bolts for double-sided fastening. It is safer and more reliable than traditional welding lifting, and has high disassembly turnover efficiency;
[0014] 3. In this scheme, during the docking process of the upper and lower cylinders, each unit of the cylinder adopts the method of built-in positioning wedges in the standard section positioning ring to control the docking interface, which effectively ensures the upper and lower docking accuracy and greatly improves the docking efficiency of the upper and lower standard section cylinders;
[0015] 4. The auxiliary tooling parts proposed in this scheme not only meet the structural safety requirements, but also have tool-type connections between the various components, which are quick to install and disassemble. This can effectively reduce the number of auxiliary devices for pipe wall welding, avoid damage to the cylinder structure, and can be used in a turnover manner to reduce costs.

The lower parts of the two L-shaped connectors 9 are connected with standard section positioning rings 5. The standard section positioning rings 5 are tightly sleeved on the butt joints of two sections of standard section pipes. There are multiple positioning wedge nails 8, and the positioning wedge nails 8 are evenly inserted into the inner side of the standard section positioning ring 5 to achieve the alignment and positioning of the upper and lower standard section pipes.
[0021] In a specific embodiment, the quick-release positioning disk 1 is an annular structure composed of two half positioning disks 1-1, and positioning disk connecting seats 2 are provided on the outer sides of both ends of the half positioning disk 1-1.

During the lifting process, the lifting device adopts an annular fastening ring and uses high-strength expansion bolts for double-sided fastening, which is safer and more reliable than traditional welding lifting, and has high disassembly turnover efficiency.
[0023] In a specific embodiment, lifting ears 4 are symmetrically provided on the outside of both sides of the quick-release positioning plate 1 for lifting.

[0026] In a specific embodiment, the L-shaped connector 9 is an L-shaped connecting rod structure with a retractable length. For example, for the standard section in the tower marker, the standard section positioning ring is connected to the bottom of the positioning plate using an L-shaped connector. The L-shaped connector is retractable, which facilitates the alignment of the standard section positioning ring with the joint of the two sections of the tube body, and facilitates the positioning wedge to control the docking accuracy of the upper and lower cylinders.

The chain hook passes through the ears on both sides of the quick-install positioning plate and lifts upward. When it is lifted to a standard section height, the next standard section is in place; standard section positioning rings are installed at the connection points through the retractable L-shaped connector on both sides of the quick-install positioning plate, and the retractable L-shaped connector places the standard section positioning ring 5cm below the interface. The standard section positioning ring is fastened to the joint of the two sections of the pipe through the positioning ring fixing bolts; when positioning the standard sections of the two sections of the pipe, the standard section is aligned and positioned by inserting the positioning wedge nails into the inner side of the standard section positioning ring, and the upper and lower pipe bodies are calibrated according to the positioning wedge nails and then welded. After the welding work is completed, the ears on both sides of the quick-install positioning plate are lifted by the chain, and the entire pipe is lifted upward to complete a lifting operation; after the lower pipe body is in place, the welding and lifting operation is repeated.
