Description

one

The invention relates to devices for assembling and welding annular and conductive seams of products of cylindrical and conical shape / assembled from sections with different angles of taper and can be used in shipbuilding and chemical engineering.

Lime is a plant for welding longitudinal and circumferential joints of cylindrical and conical shapes, containing a platform rotating in a vertical plane, equipped with a column and driving idle roller rollers mixed along it.

However, a known installation cannot be used for welding and assembling products, which consist of sections with different angles of taper, as well as products of simple form with straight lines and forming parts and products which form a broken line.

G the purpose of eliminating this deficiency in the proposed device, the column is mounted with the ability to move along the plate and is equipped with a shift plate, mounted on the hinged onojie-dvt

on the spindle i mounted on the traverse spindle i mounted with the possibility of moving- NIN along the column, this is the swivel mount,

made in the form of a detachable ring body with external projections and equipped with a floor mount mechanism, which is a swivel number of its chester with external projections, which is suitable for action -. with corresponding: grooves made on the hub of the faceplate and internal behind the grip with two gears mounted on said support — swivel, and the tilting platform is equipped with an inclined frame with guiding elements towards idlers, installed with possibility of movement along inclined; frames in said guides.

On fng. 1 shows the proposed censor, general view; in fig. 2 - spindle with supports (zy- "rotary tube; in Fig. 3 - a section along A - A in Fig. 2; in Fig. 4 - a hub of a replaceable faceplate.

Claims (2)

Tilter composit from the foundation frame 1, platform 2, parallel column 3 with the corresponding mechanisms and nodes, two drive ropikoopore 4 and a block of idle installation ropikopor 5, made with the ability to move along the guide elements mounted on the i frame 6h. The base frame 1 is made by welding The constructions are made of the profile I mate Aiylv and have supports 7 and verticular stushes Fe. The frame is installed in a pit with a F; | "tee to the side: vertical qtOBK 8 n is poured with concrete. . Platform 2 is a rigid welded structure, mounted on a hinge, but on supports 7 and fixed with pins 9 any angle on racks 8. Movable column 3 is installed in guides on platform 2 and can be first tagged with a screw actuator 1O. The nut 11 is attached to the platform and the mirror: to rearrange along the platforms 2, that. provides movement of cranes 3 along the entire length. In the vertical guide columns 3, the spindle carriage 12 is mounted, supported by a screw-drive nut 13. On the nut 13, there is a micromcli- cator 15, which turns off the actuator 14 when, in accordance with the aazbra, between the bearing surface of the nut and the carriage during the downward movement. The working pad 16 is fixed on the spindle carriage, and for access to it and to the drive 14 there is a vertical drain 17. In the case of the spindle carriage 12, a spindle 18 is fitted, which receives loads of radial bearings 19 and an uphill bearing MH of 2 O. At the outer end there is a spindle through rectangular groove, c. which is mounted a pivot bearing — a swivel consisting of an axis 21, a traverse 22, detachable from. two halves along the length of the annular body 23, which is connected with bolts 24 so that it can be rotated on the axles of the traverse 22 and the faceplate fastening mechanism in the form of an average swivel ring 25, which is an internal gear that rotates relative to the split annular body 23 by means of two gears 26 having square ends of shafts 27 so that they can be turned with a key. Body 23 and rings 25 are made with a taper of 1: 2O and have longitudinal grooves on the outer surface. Plate 28 has a hub 29, made with longitudinal grooves, which include protrusions of the housing 23 and the lance 25, Hi ring groove 30 for the passage of the protrusions of the ring 25 when turning. i Thus, the hinge structure. The pole-port can be used with cKJEH faceplates, as well as the use of a technological spacer ring, which serves to preserve the circular shape of the shell. The driving roller supports 4 are made in the form of double rubberized balan - i wheels of sierra type with a rotation drive and have the possibility of horizontal rotation for a snug fit of the wheels to the outer surface of the product being welded. The transverse movement of the drive roller & coopor is carried out with the help of a screw drive 31 along the guides mounted on the platform. The vlok of the idle mounting rollers supports two freely rotating in the longitudinal plane of the tiller wheels mounted in one common housing having the possibility of longitudinal movement along sloping frame 6, installed on the platform 2. On the direction of the main frame 6, there are mounted drives for moving the roller-bearings 5 and a transition platform 32, which serves to access the inside of the product to be welded 33. The tilter works as follows. The assembled and prepared for welding product with a spacer ring-faceplate 28 fixed on it is mounted with a lifting device on the installation rollers 5 previously raised and held in this position until the final fastening. Turning on actuators 1O and 14, column 3 is moved to the end of the product to be welded, and spindle 18 is installed against hub 29 of faceplate 28, and the protrusions of the swivel are aligned with the slots of the hubs 29.1. By turning on the drive 10, the swivel is inserted into the hole of the hub and turning , which are dried with special keys for square ends 27, install outer shafts of the middle ring of 2 5 swivels against the grooves of the hub. On this fixing product is finished. The crane is removed and further preparation for welding is carried out, which consists in moving the product, if it is not necessary, along the turning device; by means of 3 and vertical movement of the spindle carriage ;; L 2, to a landing on the drive .; ny rolkoopo. 4 and lowering the mounting rollers, setting the welded area of the product, in a horizontal position by tilting the platform 2 n securing it in the desired position with pins 9. After the product is ready for welding, include driving roller supports 4 and driving it into rotation for welding ring seams. After finishing welding, remove the product from the turn-off device. When 9nat 15k of the crane is turned on, the spindle carriage 12 is lowered. The automatic shutdown of the drive 14 means that the turntable has been released from the load and the product is kept on the weight by the crane; After that, turning the square ends of the shafts 27 by turning the swivel ring 25 with external projections against the slots of the building 26 n by moving the column 3 to the terminal t swivel from the hub of the faceplate. After that, the product is removed from the turner.
