Description
Technical field
The utility model relates to a kind of attaching/detaching apparatus of jumbo deep hole sliding bearing, mainly is 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 kinds of dismounting modes all have operating cost high, and duty cycle is long, labour intensity headlight defective.And have certain potential safety hazard during field operation.
Summary of the invention
The utility model provides a kind of attaching/detaching apparatus of sliding bearing to the problem that above-mentioned prior art exists, and is specially adapted to jumbo deep hole bearing.
The utility model solves the technical scheme that its technical problem adopted:
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 center pedestal of the attaching/detaching apparatus of sliding bearing and drag hook interconnect with hinge through adjustment pull bar, parallel rod, and the pull bar adapter sleeve is installed on the center pedestal, and the adjustment nut and the central shaft of pull bar adapter sleeve are configured to screw thread pair.
The attaching/detaching apparatus of sliding bearing be provided with self-aligning thrust roller bearing supporting between pressing plate and the nut.
The spanner of this device is a hydraulic spanner.
Center pedestal (1) top of this device is provided with the balance spanner.
Adjustment pull bar, drag hook and the parallel rod of the attaching/detaching apparatus of the sliding bearing of this device is to be the center with the center pedestal, and circumferencial direction is uniformly distributed with three groups.
The center pedestal is the center as the critical piece of apparatus of the present invention with it, and adjustment pull bar, parallel rod and drag hook are uniformly distributed with three groups and interconnect through hinge at circumferencial direction; Adjustment nut sleeve and central shaft are 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.The pedestal top is provided with the balance spanner at the center, in use, blocks the balance spanner, thereby stops the center pedestal to rotate, and 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.The parallel rod that center pedestal and circumferencial direction are uniformly distributed with, drag hook version 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.
Adjustment pull bar, drag hook and parallel rod are to be the center with the center pedestal, and circumferencial direction is uniformly distributed with three groups.Wherein center pedestal, adjustment nut sleeve, pull bar adapter sleeve, adjustment pull bar, drag hook, parallel rod are realized 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.
Through relative position between screw thread pair adjustment center pedestal and adjustment nut sleeve, drive pull bar adapter sleeve, adjustment pull bar, parallel rod motion, the opening degree of adjustment drag hook is realized the adaptation to 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 attaching/detaching apparatus of portable sliding bearing, can be in equipment uses the on-the-spot cylinder body of accomplishing different apertures the dismounting of sliding bearing, also can accomplish the dismounting and the installation of sliding bearing on the through hole in different apertures.
The utlity model has following beneficial effect:
It is convenient to implement, can on-the-spot Fast Installation, and simple to operate, cost is low, and efficient is high;
Substituted the mode of cutting, hammering, safe;
Highly versatile, reusable;
Adopt hydraulic technique to greatly reduce operation intensity.
