Abstract

The utility model belongs to the technical field of dismounting tools and particularly relates to a dismounting tool for an intermediate bearing cap. The dismounting tool is convenient to use and simple in structure. The dismounting tool comprises a bearing seat and is characterized in that a piston cylinder is fixed on the bearing seat and provided with a pipe joint, and a piston provided with a vent hole is arranged in the piston cylinder; and the piston is connected with a top block fixed at one end of a pull rod.

Description

A kind of plummer block keep extracting tool
Technical field
the utility model belongs to the extracting tool technical field, relates in particular to a kind of plummer block keep extracting tool.
Background technology
membrane pump plummer block keep is the critical component of membrane pump equipment, and bearing cap fixes through being connected double-screw bolt with casing.Because it is big to connect the double-screw bolt specification, bearing torque is big, therefore when regular maintenance and maintenance and replacing box house consumable accessory, dismantles very inconvenience of plummer block keep.
Summary of the invention
the utility model is exactly to the problems referred to above, and a kind of plummer block keep extracting tool easy to use, simple in structure is provided.
for realizing above-mentioned purpose, the utility model adopts following technical scheme, and the utility model comprises supporting base; Be fixed with piston cylinder on its structural feature supporting base; Piston cylinder is provided with pipe joint, is provided with piston in the piston cylinder, and piston is provided with air vent; Piston links to each other with jacking block, and jacking block is fixed on an end of pull bar.
as a kind of preferred version, the said jacking block of the utility model is a nut, and said pull bar is a studs.
as another kind of preferred version, the said pipe joint of the utility model is a flared fitting.
in addition, the said air vent of the utility model place is provided with plug screw.
the utility model beneficial effect: when the utility model uses; The other end and the bearing cap double-screw bolt upper end of pull bar are fixed; Thereby give pulling force that makes progress of bearing cap double-screw bolt through piston, jacking block and pull bar; Reduce its bearing torque, can easily the bearing cap nut have been turned round, it is more convenient that plummer block keep is separated with casing.
Description of drawings
further specify the utility model below in conjunction with the accompanying drawing and the specific embodiment.The utility model protection domain not only is confined to the statement of following content.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model user mode figure.
During schemed , 1 was that pipe joint, 2 is that piston cylinder, 3 is that piston, 4 is that pull bar, 5 is that jacking block, 6 is that plug screw, 7 is that air vent, 8 is that back-up ring, 9 is that sealing ring, 10 is that supporting base, 11 is that bearing cap double-screw bolt, 12 is that bearing cap nut, 13 is a bearing cap.
The specific embodiment
are as shown in the figure, and the utility model comprises supporting base 10, is fixed with piston cylinder 2 on the supporting base 10, and piston cylinder 2 is provided with pipe joint 1, is provided with piston 3 in the piston cylinder 2, and piston 3 is provided with air vent 7; Piston 3 links to each other with jacking block 5, and jacking block 5 is fixed on an end of pull bar 4.
said jacking block 5 is a nut, and said pull bar 4 is a studs; Easy to connect.
said pipe joint 1 is a flared fitting; Connect firm, good seal performance.
said air vent 7 places are provided with plug screw 6; Effectively stop fluid seepage, and easy to connect.
Adopt hermetically-sealed construction commonly used between said piston cylinder 2 and the piston 3, promptly be provided with sealing ring 9 and back-up ring 8, two sealing rings 9 small one and large one, in the piston cylinder 2 inner sealing areas that form.
are below in conjunction with course of action of description of drawings the utility model: at first the lower end with the utility model studs is screwed in the screwed hole of bearing cap double-screw bolt 11 upper ends; And supporting base 10 placed on the bearing cap 13; Suppress to flared fitting, make piston 3 jack-up nuts, the stressed bearing cap double-screw bolt 11 that passes to of nut; Realized drawing on the bearing cap double-screw bolt 11; When the sizableness of tensile force the time in the pretightning force size of bolt of bearing cap, to be back-outed from the screwed hole of bearing cap double-screw bolt 11 upper ends in the lower end of studs, just available then spanner is dismantled bearing cap nut 12 easily.
it is understandable that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection domain of the utility model.
