Description

 The invention relates to the field of general engineering, in particular to devices for positioning heavy equipment.

 A device for aligning equipment in the horizontal plane [1] is known, which is a device made in the form of blocks installed between the equipment and the foundation, consisting of upper and lower disks, between which are placed balls enclosed in a cage with radially located adjusting screws that interact with their an end face with an upper disk, and leaf springs are installed between the clips and the disks.

 Closest to the proposed device is a seismic isolator (prototype) [2], consisting of three plates lying on top of each other, and a plate shear mechanism. Each pair of plates in this device, the upper-middle and middle-lower, are supported by each other through two guide grooves with support rollers, and the guide grooves in the upper-middle plate system are oriented perpendicular to the guide grooves in the middle-lower plate system.

 The disadvantages of this device include the ability of the device to position equipment only in a horizontal plane and the need for preparatory work to position the equipment.

 The objective of the invention is the creation of a device that allows for the positioning of equipment not only in the horizontal plane, but also vertically, the creation of a device that is prepared in advance for work, eliminating the laborious preparatory work of lifting the equipment for positioning.

 The task is achieved in that the device provides all the means for positioning heavy equipment in three directions (X, Y, Z axes).

 A device for positioning equipment contains a package of three plates (upper, middle, lower). Each pair interacts with each other through two rows of support rollers laid in guide grooves made on adjacent surfaces of the plates, and the direction of the grooves in the upper-middle plate system is perpendicular to the direction of the grooves in the middle-lower plate system. This combination of plates makes it possible to displace the upper plate relative to the lower one in any direction horizontally, and the use of rollers makes it possible to transfer large loads through the joints of the plates. The device provides a mechanism for shifting plates, made in the form of a screw pair of screw-nut located between each pair of plates and interacting with the upper and lower plates. The screw rests against its ends on the protrusions of the middle plate and is screwed into the nut fixed in the upper and lower plates, ensuring the movement of one plate relative to another along the guides.

 To ensure vertical positioning (the Z axis), a jack is used, the end part of its cargo screw is pressed with a spherical head through the thrust bearing through the thrust bearing to the socket in the upper plate, allowing the screw to be tilted to the plate surface to a small extent to compensate for angular distortions during operation of the device. A flange with a protrusion is made on the jack body, which is connected to the counter flange on the side surface of the equipment support frame, and the protrusion on the jack flange enters the groove of the frame flange. Such a connection reliably transfers loads to the support from the mass of equipment. A lifting pin is installed on the jack body for lifting equipment.

 In order to orient the plates between the top plate and the jack body, a three-link hinge mechanism is installed in which the axes connecting the links between themselves and the jack body are parallel to each other, and the axis connecting the hinge to the top plate coincides with the center of the spherical end of the jack screw and is oriented perpendicular in relation to other hinge axes. This mechanism allows you to change the distance between the upper plate and the jack body, keeping the plates from turning, while the hinge links are either straightened or folded. It does not interfere with the inclination of the screw to the surface of the plate. If the screw is tilted in the direction of the Y axis, the hinge links are either straightened or folded, and if the screw is tilted in the direction of the X axis, all hinge links rotate around the axis connecting the hinge to the top plate.

 Plates (lower, middle, upper) enter into a mobile engagement according to the dovetail type. Such a connection does not interfere with the planned mutual movements of the plates along the guide grooves and, at the same time, connects the plates to each other, making the site transportable. The exit of the plates from engagement is excluded, since they are held by the shear mechanism and travel stops installed on the edges of adjacent plates.

 Loss of rollers from the guide grooves is excluded, since the rollers are held by separators, on the lateral edges of which oblong grooves are made, for the stops installed in the upper and lower plates.

 The invention is illustrated by the drawings presented in figures 1-10.

 In Fig.1, 2 shows a device for positioning equipment, consisting of a package of plates - lower 1, middle 2 and upper 3, which are supported by each other through two rows of support rollers 4, laid in the guide grooves 5 (Fig. 1), made on adjacent surfaces of plates. The direction of the grooves in the upper-middle plate system is perpendicular to the direction of the grooves in the middle-lower plate system. This combination of plates makes it possible to displace the upper plate relative to the lower in any direction of the horizontal plane, and the use of rollers makes it possible to transfer large loads through the joints of the plates.

 Between each pair of plates (Figs. 4, 5), a shear mechanism is installed, made in the form of a screw pair screw 6 - nut 7, in which screw 6 is alternately supported by its ends in the protrusions 8, 9 of plate 2 and screwed into the nut 7 fixed in the plates 1 or 3. Adapters 34 are essentially a continuation of the screw 6, which lead its working end outside the plate for ease of use.

 To ensure vertical positioning (Z axis) (figure 2), a jack is used, which is installed on the top plate. Thus, equipment connected to the jack and resting on a package of three plates has the ability to move in three directions (X, Y, Z axes).

 Outside (Fig. 2) in the central part of the upper plate (3 is mounted through the thrust bearing 14 the spherical supporting end 15 of the screw 16 of the cargo jack, on the housing 17 of which there is a flange 18 with a protrusion 19 for connecting to the side surface Ж of the frame 10 of the equipment 11 and the load pin 20 for lifting.

 In Fig.2, a positioning device is attached to the support frame 10 of the equipment 11 along its lateral surfaces W at the locations of the sling units.

 On the adjacent surfaces of each pair of plates (Fig. 1), grooves 12 and protrusions 13 are made on both sides of the grooves 5 for the rollers, which are engaged in the same way as dovetail and oriented parallel to the grooves 5. This connection does not interfere with the planned mutual movements of the plates along the guide grooves and, at the same time, connects the plates to each other, making the unit transportable.

 In Fig.4 - each row of support rollers 4 in the device is enclosed in a separator 21, on the lateral edges of which oblong grooves 22 are made, for the stops 23 installed in the upper 3 and lower 1 plates (Fig.6).

In figure 1, at the joints of each pair of plates 1, 2 and 2, 3 on the lateral edges of the plate 2, grooves 24 are made for stroke limiters 25 mounted on the edges of adjacent plates 1 and 3 - Fig.7
In FIG. 2 in order to orient the plates between the upper plate 3 and the body of the jack 17, a mechanism is installed that excludes their mutual rotation, which is made in the form of a three-link hinge in which the axes 29, 30, 31 connecting the links 26, 27, 28 with each other and with the body of the jack 17 are parallel to each other, and the axis 32 connecting the hinge with the upper plate 3 coincides with the center of the spherical end 15 of the screw 16 of the cargo jack and is oriented perpendicular to the other axes of the hinge.

 The operation of the device for positioning equipment is as follows.

 The equipment in the initial position, mounted on its support frame, is located at the factory site.

 On Fig, 9 - the choice of a place to connect to the support frame of the equipment in places of its sling is due to the fact that the loading of the frame in this case is the most rational and the stress level in the structure is less than in other cases, therefore, the support frame is subject to less deformation when conducting positioning. Such placement of the device 37 allows the load pin as a structural element of the equipment to be transferred to the device and thus reduce the dimensions of the equipment, which is an advantage for container equipment, the size of which is limited by the conditions of transportation.

 The positioning devices are completed in accordance with the circuit of FIG. 10. The diagram shows the equipment 11, the object 33, relative to which the positioning is performed, and devices that fit into the support frame of the equipment 11.

 The devices have various applications "a", "b", "c", "d" in terms of the presence of a plate shear mechanism in them, as well as their placement in the upper-middle and lower-middle systems.

 Option "a" is equipped with a shear mechanism in a pair of plates - lower-middle, providing movement of these plates along the Y axis.

 Option "b" is equipped with shear mechanisms in a pair of plates - upper-middle and middle-lower, providing movement of the upper plate relative to the lower in directions along the X and Y axes.

 Option "c" is equipped with a shear mechanism in a pair of plates - upper-middle, providing movement of these plates along the X axis.

 Option "g" has no shear mechanisms in both pairs of plates, i.e. is essentially driven.

 Variants of using the device "a", "b", "c", "g" are located next to the equipment 11, close to the connecting flanges.

 By rotating the screw 16 (figure 2) in one direction or another, the connecting flange 18 on the jack body is aligned with the counter flange on the side surface Ж of the equipment frame so that the protrusion 19 on the flange of the jack housing 17 fits into the return groove on the equipment frame 10.

 Bolts 35 tighten the flanges together.

 The lifting mechanism makes the sling of the equipment 11 behind the pins 20 and transfer the equipment in close proximity to the object 33 (Fig. 10).

 Adapters 34 (FIG. 5) actuate the shear mechanisms of the device in the “a”, “b”, “c” applications, moving the equipment 11 to a position coaxial with the object 33 (FIG. 10).

 The screws 16 of the jacks of the supports adjust the equipment 11 in height, combining it with the object 33.

 After completing the positioning, the squeezing bolts 36 (FIG. 1) are brought into contact with the foundation, unloading the positioning devices.

 Flanges 18 are undocked from the equipment frame 10, after which the devices are removed from the place of work and stored.
