Abstract
The utility model discloses an inner hole detacher belonging to a detaching tool and used for detaching components such as sleeves and bearings and the like which are installed in an inner hole. The lower end of the inner hole detacher is provided with draw hooks stretching outwards, wherein the upper ends of at least two draw hooks are hinged with a transverse frame; a stay expansion screw is matched with a stay expansion nut on the transverse frame; one end of each stay bar is hinged with the stay expansion screw, while the other end of each stay bar is hinged with one draw hook; and lifting screws are matched with lifting nuts on the transverse frame. The inner hole detacher is adopted to solve the technical problems that the existing inner detacher can not realize detaching due to the fact that the axial tensile force does not have an appropriate action point, the inner detacher adopting draw hooks is prone to drop, and the inner detacher adopting an expandable core body is too complicated in structure.
Description
Technical field
The utility model belongs to extracting tool, is a kind of to being installed in the endoporus stripping attachment that parts such as cover in the endoporus, bearing are dismantled concretely.
Background technology
Existing endoporus draws in the horse etc. axial tension with the dismounting utensil in the endoporus central axial direction, and in view of the reason of device structure, axial tension not have suitable application point sometimes, can not realize dismantling.The existing cooperation with parts end faces such as cover, bearings adopts the interior of drag hook to come off easily with the dismounting utensil, cooperates with parts endoporus such as cover, bearings to adopt expansion and shrink the interior too complicated with the dismounting utensil structure of core body.
The utility model content
The utility model will solve the existing interior dismounting utensil of using can not realize dismounting because of axial tension has suitable application point; Adopt the interior interior too complicated technology problem of dismounting utensil structure of using that comes off easily and adopt the breathing core body with the dismounting utensil of drag hook; Provide a kind of axial tension direction outside endoporus; The drag hook opening angle can be regulated, and uses reliably endoporus stripping attachment simple in structure.
In order to solve the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of endoporus stripping attachment, comprise that the lower end is outside open drag hook, and the upper end and the crossbearer of at least two drag hooks are hinged; The bloated screw of support on bloated screw rod of support and the crossbearer cooperates, and drag hook surrounds the bloated screw rod of support; One end of strut is hinged with the bloated screw rod of support, and the other end and drag hook are hinged; Hoisting nut on lift-bolt and the crossbearer cooperates, and the upright projection of lift-bolt is outside endoporus.
Rotate the support screw rod that expands, change the angle of drag hook and vertical line, thereby the fine setting drag hook forms the size of opening, make cooperating that drag hook suits with parts end faces such as cover, bearings, safe, hook parts end faces such as cover, bearing reliably.The application point that rotates the axial tension that lift-bolt produces outside endoporus, just selecting the application point of suitable location as axial tension, the utility model simple in structure.
The bloated screw of support equates with the distance of each drag hook and crossbearer hinge axis; Drag hook is evenly arranged around the bloated screw of support.
Be useful on the hinged subsequent use axis hole of drag hook and crossbearer on the crossbearer.Select to expand screw apart from next hinged drag hook of different subsequent use axis holes and crossbearer, the working range of change drag hook that can be bigger with support.
Two above hoisting nut are arranged on the crossbearer, and hoisting nut is around the bloated screw of support.
Two hoisting nut on the crossbearer expand screw point-blank respectively in the bloated screw both sides of support with support.Two hoisting nut cooperate with two lift-bolts, and the both sides of bloated screw of apportion support and drag hook make axial tension balance, stepless action.
Be useful on the subsequent use nut bore that lift-bolt and crossbearer cooperate on the crossbearer.Subsequent use nut bore has strengthened the scope of chosen axis to tension point.
The utility model has the advantages that: the bloated screw rod of support cooperates with the bloated screw of support, and under the strut effect, realization fine setting drag hook forms the size of opening, and it is safe, reliable that drag hook cooperates with parts end faces such as cover, bearings.The application point of the axial tension that lift-bolt produces outside endoporus, just selecting the application point of suitable location as axial tension, the utility model simple in structure.
Description of drawings
The structural representation of an embodiment of the utility model.
The specific embodiment
Accompanying drawings.Present embodiment is a kind of endoporus stripping attachment that is mainly used in the inserted valve valve pocket in the dismounting inserted valve valve body inner bore, and its crossbearer 4 is elongated.Crossbearer 4 adopts the more disc that also has in the practical application.The bloated screw of support of internal and external threads is installed in the upright opening in crossbearer 4 centre positions of present embodiment; The internal thread of the bloated screw of support cooperates with the bloated screw rod 2 of support; Support the external screw thread of the screw that expands and tighten nut and cooperate; To support and expand rotate handwheel 3 and the support screw that expands and is fixedly connected, the rotation support is expanded and is rotated handwheel 3 and order about bloated screw rod 2 up-downs of support.The upper end of drag hook 5 and crossbearer 4 are hinged.The bloated screw rod 2 of support is positioned on the axially bored line.Two drag hook 5 equidistant branches are listed in the bloated screw rod about 2 of support, and the hinge axis of drag hook 5 and crossbearer 4 expands screw point-blank with support.One end of strut 6 and the middle part of drag hook 5 are hinged, and the other end is hinged with the lower end of the bloated screw rod 2 of support.To support the screw rod 2 that expands is symmetry axis, and symmetrical on crossbearer 4 have 4 to be used for the hinged subsequent use axis hole of drag hook 5 and crossbearer 4, wherein two higher slightly than two other position.Two lift-bolt 1 equidistant branches are listed in the hoisting nut cooperation on bloated screw rod about 2 of support and the crossbearer 4, and the upper end of lift-bolt 1 is used for connecting promoting rotates handwheel or lifting turning handle or throw.To support the screw rod 2 that expands is symmetry axis, and symmetrical on crossbearer 4 have 2 to be used for the subsequent use nut bore that lift-bolt 1 and crossbearer 4 cooperate.The upright projection of lift-bolt 1 is outside endoporus.
