Description

(54) PIPE CONNECTION

one

The invention relates to separable pipelines and pipe racks and can be used in the mining industry in pipelines used for the delivery of long materials, such as lumber.

Known ball joint for pipes, including ends of pipes, made in the form of ball joints, which are connected to each other, and covering the sleeve, made in the form of two half-grips, interconnected by a hinge on one side and a bolt on the other. The connection allows the pipeline section to be connected at an angle of 1.

A disadvantage of the known connection is that it does not ensure reliable fixation of the ends of the pipes being joined and their uniform clamping.

The closest in technical essence is a pipe connection, comprising a holder covering the ends of the pipes to be connected and hingedly connected with them by means of semi-axes perpendicular to the longitudinal axes of the pipes 21.

The disadvantages of the known compounds are the inconvenience of its use for the delivery of long materials and the complexity of installation.

The aim of the invention is to enhance the functionality of the connection and provide ease of installation.

This goal is achieved by the fact that in a pipe connection, including a sleeve, covering the ends of the pipes to be connected and pivotally connected to them by means of

10 axes, perpendicular to the longitudinal axes of the pipes, the sleeve is made in the form of a cylinder with diametrically located grooves at the end, and the grooves are figured and in them are the semi-axes of one of the pipes.

FIG. 1 shows the connection of pipes, a general view in section; in fig. 2 shows section A-A in FIG. one.

The pipe connection includes a ferrule 1, one end of which is provided with longitudinal

20 with slots 2 and 3 and supporting removable sleeves 4 and 5, and the other end is made with shaped grooves b and 7. One end of the clip is connected to the end of one of the pipelines 8 by means of semi-axes 9 and 10 through the bushings 4 and 5. The second end of the clip is connected by figured grooves 6 and 7 with the end of the pipeline 11 provided with semi-axes 12 and 13. The ends of the pipelines 8 and 11 are shaped as sockets 14 and 15. The rotation axes 16 and 17 of the semi-axes 9 and 10, 12 and 13 are perpendicular to the longitudinal axis 18 of the pipelines and perpendicular to each other. The joining of pipelines is carried out as follows. In the longitudinal grooves 2 and 3 of the yoke 1 are inserted the axles 9 and 10 of the end of the pipeline 8. On the axles 9 and 10 through the holes at the ends of the longitudinal grooves, the sleeves 4 and 5 are put on and fixed in a known manner, for example with a tongue and pin. The semi-axles 12 and 13 of the end of the conduit 11 are inserted into the shaped grooves 6 and 7, turned up to the stop, and fixed with a return movement in the L-shaped pocket of the shaped groove. The assembly sequence can be carried out starting from the liner of the pipeline 11, i.e. in the reverse order. For a more versatile assembly of the joint on the yoke 1, additional pairs of shaped grooves may be provided and made relative to the main pair at a distance of 30 °,

/ 45 ° or 60 °, which will allow the pipeline to become bent in any direction. The technical and economic effect of the proposed pipe joint is that it allows the delivery of lengthy materials and provides convenient and quick assembly and disassembly. Claims The connection of pipes, including the sleeve, which covers the ends of the connected pipes, and is hinged to them by means of semi-axes perpendicular to the longitudinal axis of the pipes, is characterized in that cylinder with diametrically spaced grooves at the end, and the grooves are figured and in them are the semi-axes of one of the pipes.
