Description

(54) DEVICE FOR WELDING SECTIONAL DRAINS

one

The invention relates to welding, in particular, to the design of an apparatus for assembling and rotating during the welding process of sectional bends of pipelines and other similar products.

A device for welding sectional bends is known, which includes a plate-slider mounted on the base and an attachment unit.

However, in this device, it is welded. The driver is mounted cantilever on the rails, which, when installing a large diameter outlet, reduces the reliability of fastening, increases the strength and dimensions of the deformation rotator, 5 retraction at the attachment point.

It is also known a device for welding sekdionnk bends, containing a faceplate mounted on the base and a U-shaped drive bracket mounted on a facepipe 20, on the consoles of which the attachment unit JlOB is installed, made in the form of a frame with clamping jaws 2.

A disadvantage of the known device is low productivity, since in order to install the welded joint to the required position, it is necessary to alternately rotate the clip relative to the plate and the weld to the bracket.

The aim of the invention is to increase labor productivity by simplifying the installation of the welded elbow to the starting position.

Goal Achieved A device containing a U-shaped drive bracket mounted on the base of the face plate and mounted on the face plate, on the consoles of which a tap fixing unit is installed, in the form of a frame with clamping jaws, equipped with bars, one of which is hinged the plate is parallel to the bracket bracket, and the other is hinged to the first and also pivotally to one of the brackets of the bracket and is placed parallel to the plate, while on the bar that is pivotally connected to the console, fixed xator, inter. acting with the frame of the outlet fixing unit. FIG. 1 shows a device for welding sectional bends, laterally, in FIG. 2 is a view A of FIG. one; in fig. 3 section bb in fig. 1. The device consists of a base 1, on which a drive 2 is mounted, on the shaft 3 of which a placable 5 is installed in bearings 4. Shift hingely, rotatably about axis 6, parallel to the plane of the washer 5, the U-shaped clip 7 sec. 8. In a plane passing through the longitudinal axis of one of the consoles 8 and perpendicular to the axis 6, traces 9 and 10 are placed. The ten hectares 9 are pivotally mounted on the stand-up bracket parallel to the console. It is pivotally connected with a hectare of 10, placed parallel to the washer. Tubes 9 and 1O form a hinged parallelogram with one of the console 8, as well as with a washer 5, in which 1Q connects console 8 to rotate about axis 11 parallel to axis 6. On plate 5 there is a bracket 12, on the nut 13 is pivotally mounted with the trunnions 14, the axis of which is parallel to the axis 6. A screw 15 interacts with the nut 13, one end of which is equipped with a handwheel 16, and the other end is connected with a double thrust bearing 17 and the hinge 18 to the console 8. Vilt 15 is located in a plane perpendicular to the axis 6 ... On to The arms of the consoles 8, coaxially with the throttle 1O, with the possibility of rotation relative to the axis 11 are installed the mount from the waters 19, which includes the frame 20, the screw 21, extruded with the right and left threads and equipped with handwheels 22. On the screw 21 is symmetrical relative to the axis of rotation of the slider plate 5, racks 23 with jaws 24 are installed. On clamp 10 there is a latch 25, which interacts with the frame 20. The device operates as follows. . The weld bead is brought into the attachment unit 19 and the handwheel 22 is turned by pressing it with the jaws 24. The bend is installed so that the jaws 24 are located near the center of the body of the tap in the area between the joints being welded (for example, the joints and T). For welding the joints 11 and W, the retraction together with the fastening assembly 19 is rotated relative to the axis so that the welded joint is installed perpendicular to the axis of rotation of the faceplate 5. In this position, the retraction is secured by the latch 25. By rotating the handwheel 16, the bracket 7 together with turning by turning until the axis of the joint to be welded is not aligned with the axis of rotation of the faceplate 5, while the angle of inclination of the joint to be welded relative to the axis of rotation of the plate 5 does not change. This slot position is the starting point for welding. In the process cBajpKw. the actuator 2 rotates the plate 5 along with the weld bend. For welding 1 of the joint, the retraction together with the fastening assembly 19 is rotated relative to the axis 11 by an angle close to 180, after which the operations for installing the weld joint to the initial position are repeated. To ensure the removal of the outlet, when it is installed in its initial welding position, the rotation of the frame 7 and the fastening assembly 19 is best done when the frame 7 is located in a vertical plane. In this case, the rotation of the outlet is pro- gated in a horizontal plane. In order to facilitate the rotation of the weld branch, the assembly 19 may be provided with a mechanical drive. In order to facilitate the installation of the welded joint perpendicular to the axis of rotation of the plate and the alignment of their axes, special removable patterns can be used (not shown). The use of this device for welding sectional bends by 40-60% compared to the known method reduces the installation time of the retraction to the initial position, since the device ensures the orientation of the retraction relative to the plate in the process of aligning its rotation with the axis of the welded joint. g as a result, there is no need for repeated alternate rotation of the bracket relative to the plate and welded outlet relative to the bracket, as is the case in the known device, as a result of which labor productivity increases. Claims of the Invention A device for welding sectional bends, comprising a base plate mounted on the base and a H-shaped drive bracket pivotally mounted on the base plate, on the consoles of which a branch assembly is installed. made in a vice frame with clamping jaws, which are designed to increase productivity by ensuring simultaneous movement of the cramp and turning of the outlet fixing unit, it is equipped with rods, one of which is hinged on the faceplate is parallel to the bracket bracket, and the other is pivotally connected to the first and also pivotally to one of the bracket brackets and is placed parallel to the faceplate, with V 99 Fig.1, this is attached to a console hingedly connected to the console with a clamp, which interacts with the frame of the attachment point from the water.
