Description
Technical field
The present invention relates to the pivoting support of big machinery, particularly a kind of detachable pivoting support of big machinery and the isolated plant that is connected the connection bearing pin.
Background technology
Bear the big machinery of capsizing moment, such as runabout crane, between its upper and lower car body pivoting support is arranged.The standard pivoting support is by the inner ring 1 that is connected with the crane body, the external toothing 2 that is connected with the crane descending body, and rolling body 3 forms (seeing Fig. 1).By the rotation of the miniature gears on the swing type mechanism, drive upper body and rotate.When specification of equipment is large, oad surpasses the permission size, upper and lower car body need to be separated, in the time of could satisfying walking or traffic condition, the standard pivoting support can't satisfy operating needs.Mainly contain following two kinds of reasons: the one, high strength bolt is tightened by predetermincd tension to be disposable, must to change during dismounting; The 2nd, upper and lower car body connecting portion space is little, the dismounting difficulty.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, the device of a kind of releasable pivoting support and plug bearing pin is provided, solve the problem that the standard pivoting support is difficult for fractionation.
The present invention is achieved through the following technical solutions its goal of the invention.
A kind of releasable pivoting support, comprise: the inner ring that is connected with the crane body, the external toothing that is connected with the crane descending body, and rolling body, it is characterized in that: described external toothing is comprised of top gear ring and lower support ring, the lower end of described top gear ring is inserted in the ring body of lower support ring, and along its circumference uniform distribution connecting bore radially, insert in the described connecting bore with bearing pin again, top gear ring and lower support ring are connected as a single entity, the termination of described bearing pin is provided with bolt, outer at described lower support ring, be positioned at described radially connection hole, be provided with for upper annular slot and lower annular slot that pin inserting-pulling device is installed, described lower support is equipped with the connecting bore with the crane descending body.
A kind of device for releasable pivoting support plug bearing pin, it is characterized in that: the device of described plug bearing pin is by power pump station, oil cylinder, support body three parts form, contain oil pump, quick plug, the power pump station of change-over valve, provide pressure oil to described oil cylinder, described support body is connected with clamp by pin, the termination of described support body is stuck in the described upper annular slot, the termination of described clamp is stuck in the described lower annular slot, described oil cylinder is installed in the middle part of described support body, the piston rod head of described oil cylinder is provided with draw-in groove, and described draw-in groove can be connected with the head of described bolt.
The present invention compared with the prior art, inner ring is identical with the standard pivoting support with rolling body, its distinguishing characteristics is: the external toothing of pivoting support has been divided into two parts, and top is gear ring, and the bottom has increased carrier ring; Original high strength bolt connecting bore is located on the lower support ring; At gear ring and lower support ring one circle lateral aperture is set, is connected as a single entity by bearing pin.Insertion by bearing pin with extract, the connection that realizes pivoting support with separate.Be provided with for the circular groove that the insert-pull pin instrument is installed at carrier ring.The mounting or dismounting of bearing pin realize by oil cylinder, and the pressure oil of oil cylinder is provided by power unit, is provided with change-over valve, and the control oil cylinder moves reciprocatingly, and the antagonistic force of oil cylinder is born by the accessory that is contained on the circular groove.
By adopting the carrier ring structure, by circular groove and areal of support realization location, bearing pin is realized connecting and separating, and realizes pin assembling/disassembling/by special tool, has solved the difficult difficult problem that splits of standard pivoting support.It is simple in structure, easy to operate, safe and reliable that the present invention has advantages of.
