Abstract
The utility model provides a tooling for keeping a large-diameter cylinder round, which is labor-saving to install, and comprises an upper semi-ring and a lower semi-ring, wherein the end part of the upper semi-ring or the lower semi-ring is fixed with one end of a connecting plate, the other end of the connecting plate is provided with a connecting plate positioning hole, the end part of the lower semi-ring or the upper semi-ring is provided with a ring positioning hole corresponding to the connecting plate positioning hole, and a pin column penetrates through the connecting plate positioning hole and the ring positioning hole in an application state; the ends of the upper semi-ring and the lower semi-ring are fixedly connected with roller shafts, rollers are sleeved on the roller shafts, and the outer circular surfaces of the rollers are tangent to the outer circular surface of the large-diameter cylinder.
Description
Technical Field
The utility model belongs to the technical field of metal large-diameter cylindrical chemical equipment, and particularly relates to a tool for keeping a large-diameter cylinder round.
Background
In chemical equipment such as a carbonization tower, a condensation tower and the like, the diameter of a cylinder body is large, and the cylinder body can be greatly deformed when being horizontally arranged, so that the processing and manufacturing of the assembly welding cylinder body, the installation of tower plates in the cylinder body and the like are affected. The tool for preventing the deformation of the cylinder body, such as the large-diameter thin-wall cylinder welding deformation-preventing tool with the bulletin number of CN203236180U, disclosed in the prior art, has the problem that the tool is laborious to install in use because the cylinder body which is horizontally placed on the carrier roller is deformed before the deformation-preventing tool is installed.
Disclosure of Invention
In order to solve the problems of the deformation-preventing tool in the prior art, the utility model provides a tool for keeping a large-diameter cylinder round, which saves labor in installation.
The utility model relates to a tool for keeping a large-diameter cylinder round, which comprises an upper semi-ring and a lower semi-ring, wherein one end of a connecting plate is fixed at the end part of the upper semi-ring or the lower semi-ring, a connecting plate positioning hole is formed at the other end of the connecting plate, a ring positioning hole corresponding to the connecting plate positioning hole is formed at the end part of the lower semi-ring or the upper semi-ring, and a pin column penetrates through the connecting plate positioning hole and the ring positioning hole in an application state; the ends of the upper semi-ring and the lower semi-ring are fixedly connected with roller shafts, rollers are sleeved on the roller shafts, and the outer circular surfaces of the rollers are tangent to the outer circular surface of the large-diameter cylinder.
The inner circumferential walls of the upper half ring and the lower half ring are respectively fixed with a protection edge in the axial direction.
The ends of the upper semi-ring and the lower semi-ring are provided with tensioning holes, and hooks of the manual tensioner are connected in the tensioning holes during installation.
Compared with the prior art, the deformation-preventing tool has the following advantages: 1) The roller arranged on the tool reduces friction between the end part of the tool and the outer circular surface of the large-diameter cylinder during installation of the tool, and reduces difficulty in restoring the deformed cylinder body to be circular. 2) The deformed cylinder body is restored to be round by adopting the tensioner, so that operators can exert force more easily, the labor efficiency is improved, and the labor intensity is reduced.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model.
Fig. 2 is a right side view of fig. 1 (tensioner hidden not shown).
Detailed Description
The following describes the embodiments of the present utility model further with reference to the accompanying drawings:
as shown in fig. 1 and 2, the tool for keeping a large-diameter cylinder round comprises an upper half ring 1 and a lower half ring 2, wherein one end of a connecting plate 3 is fixed at the end part of the lower half ring 2, a connecting plate positioning hole is formed at the other end of the connecting plate 3, a ring positioning hole corresponding to the connecting plate positioning hole is formed at the end part of the upper half ring 1, and a pin 4 penetrates through the connecting plate positioning hole and the ring positioning hole in an application state; the inner circumferential walls of the upper half ring 1 and the lower half ring 2 are respectively fixed with a protection edge 5 in the axial direction; the end parts of the upper semi-ring 1 and the lower semi-ring 2 are provided with tensioning holes, hooks of the manual tensioner 6 are connected in the tensioning holes during installation, the end parts of the upper semi-ring 1 and the lower semi-ring 2 are fixedly connected with roller shafts, rollers 7 are sleeved on the roller shafts, and the outer circular surfaces of the rollers 7 are tangent to the outer circular surface of the large-diameter cylinder 8.
Claims (3)
