Description

The utility model relates to mechanical engineering, car building, boiler building, and in particular to devices for assembling for welding reinforcing elements in the form of channels, angles or trough profiles on the cylindrical outer surface of containers, for example, boilers, apparatus, etc.

Known is the most common method of assembling reinforcing elements for welding on a cylindrical outer surface using a wedge and a bracket. Next to the reinforcing element to be installed, a bracket (having an L-shaped or U-shaped shape) is welded onto the cylindrical outer surface of the product body. A pointed wedge is driven between the surface of the bracket and the reinforcing element. As the wedge is driven in, the reinforcing element is pressed tightly against the body of the product, thereby eliminating the gap between the mating surfaces. After eliminating the gap at the place of installation of the bracket and driving in the wedge, the reinforcing element is welded to the body of the product by welding.

The disadvantage of this method of assembling reinforcing elements for welding on the cylindrical outer surface of the products is the high labor intensity and cost of manufacturing products, since additional material and time resources are spent on the installation and subsequent dismantling of auxiliary devices (brackets) on the boiler body.

A device for assembling for welding bandages with shells is known, characterized in that it contains a frame, drive roller bearings mounted on it for placing an assembled product on them, tension modules consisting of a pair of tension mechanisms, each of the tension mechanisms contains a welded metal frame with linear guides fixed on it, a carriage and a screw gear kinematically connected to the flywheel for linear movement of the carriage and its coordination relative to the bandage on a pneumatic cylinder with a rod fixed in supports on the racks of the carriage, a pneumatic cylinder with a rod fixed by means of axes on the forks of the pneumatic cylinder rod, the lugs of the connecting links of the clamping devices, while each of the clamping devices contains a flexible metal structure consisting of two identical parts of multi-link elements, consisting of smooth rollers and hollow rollers, step by step connected by intermediate plates, while bent brackets are fixed at the ends of the clamping devices, forming having a single lock (RU, invention No. 2755229, IPC B23K 37/04 (2006.01), publ. 09/14/2021).

The disadvantage of this invention is the complex design of the device, as well as the inability to attach reinforcing elements to the outer surface of the cylindrical container.

Close analogues of the claimed device were not found.

The technical problem of assembly for welding of reinforcing elements with a body of a cylindrical container is the presence of increased structural gaps that occur between the mating surfaces of the reinforcing elements and the surface to which they are adjacent. Increased gaps are the result of increased deviations from flatness, straightness, helicity of the reinforcing elements of corners, channels, trough profiles from the standard parameters laid down in the design documentation.

A technical problem is the structural gaps that occur between the mating surfaces of the reinforcing elements and the surface to which they are adjacent.

EFFECT: elimination of structural gaps arising between the mating surfaces of the reinforcing elements and the surface due to the use of a device for assembling for welding reinforcing elements in the form of channels, angles or trough profiles with a cylindrical container body without additional mounting of auxiliary devices to the body while reducing the time for assembling reinforcing elements with a cylindrical container body.

A device for assembling for welding reinforcing elements in the form of channels, angles or trough profiles with a body of cylindrical containers includes a trolley 1, on which a pneumatic cylinder 2 and levers 3 are installed through brackets 4 and 5, in the upper part of which a pressure roller 12 is installed on the guide 11. The levers 3 are connected to each other through the axis 7, the screw 8 and the guide 11. When the handle 10 is rotated along the screw 8, the displacement there is a nut 9, which in turn moves the pressure roller 12 longitudinally along the guide 11.

Works the claimed device on the example of the boiler tank as follows.

The boiler body of the tank 14 is installed on the universal roller rotators 15. The reinforcing element 13 is installed on the boiler body of the tank 14 and tacked by welding. The reinforcing element 13 can be in the form of a corner, a channel, a trough profile. Moving along the rail guides, the trolley 1 of the device is brought in front of the reinforcing element 13 of the tank boiler body. By turning the handle 10 of the screw 8, the nut 9 moves the pressure roller 12 longitudinally along the guide 11, thereby accurately positioning the pressure roller 12 relative to the shape of the reinforcing element 13. Compressed air is supplied to the pneumatic cylinder 2, driving the pneumatic cylinder rod. As the pressure in the pneumatic cylinder 2 increases due to compressed air, the rod through the fork 6, which is fixed on the axis 7, drives the levers 3, which pivotally rotate in the bracket 4. At this moment, the pressure roller 12, which is installed in the upper part of the levers 3, acts on the reinforcing element 13, pressing it against the boiler body of the tank 14 and at the same time reducing the structural gap 15. After full pressing, the reinforcing element 13 welded by welding to the tank boiler body 14. Further, reducing the air pressure in the pneumatic cylinder 2, the pressure roller 12 is removed together with the levers 3 from the reinforcing element 13 of the tank boiler body.

By rotation on the universal roller rotators, the tank boiler body is set to the next position and the operation is repeated until the reinforcing element 13 is assembled over the entire area of contact with the tank boiler body 14.

To be able to assemble reinforcing elements 13 with different profile designs (channel, angle, trough profile), the shape (barrel-shaped, U-shaped, V-shaped, omega-shaped) and the material (metal, rubber, polyurethane, silicone, plastic) of the pressure roller 12 is selected and installed on the device individually depending on the task.

Reducing the assembly time of the reinforcing elements with the body of the cylindrical container is ensured by eliminating the operation of additional mounting on the body of the container of auxiliary devices such as a bracket (having an L-shaped or U-shaped shape) by welding, with its further dismantling, and also by eliminating the need to drive a wedge between the bracket and the reinforcing element of the cylindrical container body. When using the proposed device, the complexity of assembling reinforcing elements with a cylindrical container body is reduced on average from 50 minutes to 20 minutes.

According to the regulatory documentation for welded joints, the maximum gap when assembling reinforcing elements from the cylindrical outer surface of the tanks can be up to 3 mm. When using the proposed device, it is ensured that structural gaps are eliminated when assembling reinforcing elements from the cylindrical outer surface of containers up to 0.1 mm. This gap has been confirmed by tests.

Thus, thanks to the claimed utility model, used for its intended purpose, the problem of eliminating structural gaps is solved, as well as reducing the time for assembling for welding reinforcing elements in the form of channels, angles or trough profiles with a cylindrical container body.
