Description
Technical field
The present invention relates to a kind of jumbo deep hole dismounting and bearings mounted device, mainly be applicable to the dismounting and the installation of sliding bearing in jumbo hydraulic pressure, pneumatic cylinder and the fairlead.
Background technology
Because of being interference fit between sliding bearing and its mount pad, bring very big difficulty for the installation and removal of sliding bearing.In existing maintenance technique, the dismounting of sliding bearing mainly contains dual mode in the jumbo upper cylinder body: 1. sliding bearing band mount pad or lathe bed are pulled down in the lump, be carried to the machining scene, adopt the mode of boring or drilling to remove sliding bearing; 2. if sliding bearing mount pad or lathe bed are excessive, overweight, can't carry or the machining clamping very at need, can only adopt the on-the-spot mode of removing, destroy sliding bearing shape with flame cutting or other hand-operated tools, piecemeal is removed.And the installation of sliding bearing mainly also has dual mode in the jumbo upper cylinder body: 1. sliding bearing band mount pad or lathe bed are pulled down in the lump, be carried to the machining scene, make special tooling, adopt forcing press to install; 2. adopt the mode of hammering directly to install at the scene.These several dismounting modes all have the operating cost height, and duty cycle is long, labour intensity headlight defective.And have certain potential safety hazard during field operation.
Summary of the invention
The present invention is directed to the problem that above-mentioned prior art exists, a kind of dismounting and bearings mounted device are provided, be specially adapted to jumbo deep hole bearing.
The technical solution adopted for the present invention to solve the technical problems is:
The present invention includes the center pedestal, support pressing plate drag hook, nut, spanner, the center pedestal is connected with drag hook, supports pressing plate and nut sleeve and is loaded on the pedestal of center, and nut and central shaft are configured to screw thread pair, and spanner is placed on the nut.
The present invention is that also spanner can be a hydraulic spanner.
The center pedestal is the center as the critical piece of apparatus of the present invention with it, adjusts pull bar, parallel rod and drag hook at circumferencial direction uniform three groups and interconnect by hinge; Adjust nut sleeve and central shaft and be configured to screw thread pair; The pull bar adapter sleeve is hinged with the adjustment pull bar.The nut and the central shaft on device top are configured to screw thread pair.
Between support pressing plate and nut, be provided with self-aligning thrust roller bearing, to reduce the unbalance loading on the center pedestal that causes because of the sliding bearing center and the support pressing plate upper surface error of perpendicularity to greatest extent.Hydraulic spanner is enclosed within nut top, and special-purpose small-sized hydraulic station is connected with high-pressure hose snap joint with hydraulic spanner.Be provided with the balance spanner on pedestal top, center, in use, block the balance spanner, thereby stop the center pedestal to rotate, assurance center pedestal only produces and moves axially.
Among the present invention, under the support of supporting pressing plate, nut changes into the tensile force of centering arbor support with driving torque, makes the center pedestal drive drag hook and moves up and down.Parallel rod, drag hook version that center pedestal and circumferencial direction are uniform can be passed to the sliding bearing bottom surface equably with the tensile force of center pedestal.
Adjust the compound mode of nut sleeve, pull bar adapter sleeve, adjustment pull bar, can adjust the opening degree of drag hook efficiently, adapt to the dismounting of the sliding bearing of different inner diameters.
Nut is chosen as hexagon nut with flange.
Adjusting pull bar, drag hook and parallel rod and be with the center pedestal is the center, uniform three groups of circumferencial direction.Wherein the center pedestal, adjust nut sleeve, pull bar adapter sleeve, adjust pull bar, drag hook, parallel rod realize effects such as the adaptation of different apertures sliding bearing and axial support, connection, carryings; The axial tension fixing and the centering arbor support that supports pressing plate, self-aligning thrust roller bearing, hexagon nut with flange, hydraulic spanner realization package unit provides power.
Adjust the center pedestal and adjust relative position between nut sleeve by screw thread pair, drive pull bar adapter sleeve, adjustment pull bar, parallel rod motion, adjust the opening degree of drag hook, realize adaptation the sliding bearing of different inner diameters.Installing under the operating mode, the version that drag hook and sliding bearing inwall are fitted plays the support to bearing, the stability the during axial displacement of raising bearing.Nut and thrust adjustment roller bearing compound mode will rotatablely move and change into the rectilinear motion of center pedestal, reduce driving power.Hydraulic spanner can reduce labour intensity greatly.
Apparatus of the present invention are as a kind of portable dismounting and bearings mounted device, can be in equipment uses the on-the-spot cylinder body that finish different apertures the dismounting of sliding bearing, also can finish the dismounting and the installation of sliding bearing on the through hole in different apertures.
The present invention has following beneficial effect:
It is convenient to implement, can on-the-spot Fast Installation, and simple to operate, cost is low, the efficient height;
Substituted the mode of cutting, hammering, safe;
Highly versatile, reusable;
Adopt hydraulic technique to greatly reduce operation intensity.
Description of drawings
Concrete structure of the present invention further describes by embodiment with reference to the accompanying drawings.
Fig. 1 is the front view of the present invention under the dismounting operating mode.
Fig. 2 is that the present invention is at the front view of installing under the operating mode.
Among Fig. 1: 1. the center pedestal, 2. adjust nut sleeve, 3. the pull bar adapter sleeve, 4. adjust pull bar, 5. drag hook, 6. parallel rod, 7. support pressing plate, 8. self-aligning thrust roller bearing, 9. nut, 10. hydraulic spanner, 11. portable hydraulic stations, 12. sliding bearings, 13. apparatus bodies, 14. balance spanners;
The specific embodiment
Below by a specific embodiment, and in conjunction with the accompanying drawings, the present invention is set forth.
Consult Fig. 1, Fig. 2, at first package unit is placed and treat directly over the dismounting plain bearing bore, rotation nut sleeve 2 moves it downwards, dwindles drag hook and center pedestal 1 distance by adjusting pull bar 4, then drag hook 5 is stretched into sliding bearing 12 endoporus.By adjusting nut sleeve 2, drive pull bar adapter sleeve 3, adjustment pull bar 4, parallel rod 6 drive drag hooks 5 adjusting opening degrees, make the drag hook 5 and sliding bearing 12 inwalls and lower surface applying of putting into the hole.After waiting to support pressing plate 7, self-aligning thrust roller bearing 8, hexagon nut with flange 9, hydraulic spanner 10, Hydraulic Station 11 etc. and installing and fixing, start hydraulic spanner, need this moment to use balance spanner 14 balance nuts 9 to rotate the moment of torsion of the centering arbor support 1 that produces, prevent that center pedestal 1 from producing gyration, center pedestal 1, drag hook 5 drive the sliding bearing generation and move axially like this, can realize the dismounting and the installation of sliding bearing.
