RU2412794C1 - Self-aligning support - Google Patents

Abstract

FIELD: machine building.

SUBSTANCE: invention refers to machine building and can be used for balanced installation of big-size machines. The self-aligning support consists of a base with a spherical recess, of an insertion with a spherical convex low side and of a counter wedge for contacting an installed item. The insertion is a wedge-like and is rigidly fastened to the self-aligning item by means of bolts via s slit in the counter wedge. The counter wedge and insertion are interconnected by means of pins hinged on the insertion and a strap secured on the counter wedge. Free ends of pins pass through orifices in the strap and are fixed in these orifices with nuts. Beneath the base there is arranged a device of a rotation stabilisation in form of a bar trussed with two frames; also, the frames project on ends of the support upward and function as guides for the insertion.

EFFECT: control over height of support.

Description

The invention relates to mechanical engineering and can be used for uniform installation of large-sized machines.

Known self-supporting inlet support (patent RU No. 2202459, 2000.12.18), comprising a housing in which a spring-loaded support rod with a wedge protrusion and a stop installed with the possibility of adjusting its position along the axis of the support, and a locking wedge designed for interaction with wedge surfaces with a cracker installed with the possibility of lateral movement, the drive of the locking wedge, made in the form of a piston mounted on a locking wedge with the possibility of axial movement and interaction with the ring a protrusion at its end and housed in a stepped opening of the housing, characterized in that the support rod and the locking wedge are collinear and connected with the locking connection, the supporting rod is made with a through axial stepped hole with an annular protrusion and with a longitudinal groove, while the locking connection is made in in the form of a stud with an adjusting nut rigidly mounted on a locking wedge and located in a stepped hole of the support rod with the possibility of interaction of the adjusting nut with its annular protrusion while the housing is made of two parts located along the axis of the support and interconnected by means of a flange, in one of the parts there are diametrical grooves open towards the housing connector and designed to accommodate the ends of the cracker.

Known self-aligning shaft support (patent RU No. 2127376, 1994.03.17), which includes a casing with an axis passing through its internal space, having first and second axial sides within the inner space of the specified casing, a guide that controls rotation and return translational motion of the shaft relative to the casing. A flange is attached to the guide, the first bearing being installed between the flange and the first axial surface of the casing, and the second bearing is installed between the flange and the second axial surface of the casing. These components interact to provide the possibility of rotational and reciprocating motion of the shaft, and also allow the shaft to perform angular movement relative to the casing under high pressure conditions.

The closest analogue is a self-aligning spherical support (copyright certificate SU No. 485853, 02.03.73), consisting of a base in which a spherical recess is made, a hemispherical insert that is inserted into the support. A part is installed on the flat side of the liner, under the weight of which the liner rotates in the support until the part lies with its entire base plane on the liner.

The technical result of the invention is the ability to change the vertical elevation of the circuit, as well as providing the ability to include a self-installation system in the finished foundation system and support of the installed product.

The technical result is ensured by the fact that the self-aligning support includes a base with a spherical recess, an insert with a spherically convex lower side and an oncoming wedge for contacting the installed product. The insert is made wedge-shaped and is rigidly attached to the product to be installed using bolts through a slot in the oncoming wedge, the oncoming wedge and the insert being interconnected by pins pivotally mounted on the insert, and a strap fixed on the oncoming wedge through which openings are passed through the free ends studs fixed in the holes with nuts, while under the base there is a rotary stabilization device in the form of a rod pulled together by two frames, the frames protruding upward along the edges of the support and are tsya guides for the insert.

The radii of the spherical recesses of the base and the convex part of the liner are selected in the range from 1600 mm to 2400 mm, due to which the pore elements can have rises of not more than 10 mm. This allows you to embed the supports in the finished foundation instead of standard plates.

The support also has a rotary stabilization device (6 in FIGS. 1 and 2), which is a rod placed under the base and pulled together by two frames. Moreover, the frames protrude at the edges of the device and are guides for the liner. Due to this, the rotation of the ball joint is excluded.

The implementation of the invention

A base with a spherical recess, a liner with a spherically convex lower side, and a counter upper wedge are made of steel 35.

In terms of products are squares with sides of 310 mm. The radius of the sphere is 1800 mm. A recess is made in the recess for the grease. In the oncoming wedge, a slot is made 90 mm long and 50 mm wide.

On two opposite sides of the liner in the plane of the liner pins are pivotally mounted, the free ends of which are threaded. A plate protruding beyond the size of the side of the wedge is fastened to the side of the oncoming wedge of greater thickness. The free ends of the plank have holes.

Mortgage set as follows.

The base is laid on the foundation with a spherical recess up and fixed with bolts or welding.

Lay the liner on the base so that the convex portion of the liner lies in the recess of the base. A bolt is screwed into the outside of the liner.

A counter wedge is placed on the insert, passing the bolt through the slot.

The loose ends of the liner studs are inserted into the holes in the bar on the oncoming wedge and the studs are secured with nuts.

Thus, the required number of mortgages is established around the perimeter of the support of the installed product. Next, with the help of jacks above the mortgages at the required height, the installed product is hung on the support. By tightening the nuts on the studs, the oncoming wedges move so that the upper surface of each with the maximum area is in contact with the lower surface of the product support.
