The purpose of set a distance, but the technology is inconvenient to use, and working efficiency is low.
Summary of the invention
To solve the above-mentioned problems, the purpose of this utility model is to disclose a kind of collector shoe flexible bearing extracting apparatus, nothing
Flexible bearing need to entirely be taken out from collector shoe, so that it may reach collector shoe job state, to improve working efficiency.
The utility model is achieved through the following technical solutions: a kind of collector shoe flexible bearing extracting apparatus, including pressure
Power source and extract component, the pressure source by being connect with the extraction component communicating pipe, the extraction component include with it is described
The hollow jack of communicating pipe connection, is connected to the hollow sleeve of the hollow very heavy top end face, and through described hollow
The input shaft of jack and hollow sleeve, and the input shaft is pierced by the end of flexible bearing and is fixed with fixing piece, the flexibility
Bearing is in interference fit with by stream arm.
Further, the pressure source includes the pressure pump connecting with the communicating pipe, and the pressure pump using
Hydraulic hand-pump；The communicating pipe is hydraulic tube.
Further, it is described by stream arm include T-type busbar connector arm, be symmetrically fixed on the folder at the T-type busbar connector arm both ends
Ear A and folder ear B, and the cavity with flexible bearing interference fit is offered in the folder ear A and folder ear B.
Further, the outer diameter of the hollow sleeve is equal to the outer diameter of the folder ear A and the folder ear B.
Preferably, the input shaft is bolt；The fixing piece is nut.

Specific embodiment
The utility model is described further with reference to the accompanying drawing.
A kind of collector shoe flexible bearing extracting apparatus, as depicted in figs. 1 and 2, including pressure source 1 and extraction component 2, wherein
Pressure source 1 includes pressure pump 11 and communicating pipe 12, i.e. pressure pump 11 and extraction component 2 by being connected in one communicating pipe 12.
As shown in Figures 2 and 3, extracting component 2 includes the hollow jack 21 connecting with communicating pipe 12, is connected to hollow thousand
The hollow sleeve 22 of 21 end faces of jin top, and through the input shaft 24 of hollow jack 21 and hollow sleeve 22, and input shaft
24 respectively with the 22 inner surface sliding contact of hollow jack 21 and hollow sleeve.
Shown in as shown in Figure 2, Figure 3 and Figure 4, the one end of hollow sleeve 22 far from hollow jack 21 is abutted with by stream arm 3, wherein
Included T-type busbar connector 31 by stream arm 3, be symmetrically fixed on the folder ear A32 and folder ear B33 at 31 both ends of T-type busbar connector, and presss from both sides ear A32
The cavity (not shown) being interference fitted with flexible bearing 4 is offered in folder ear B33, press from both sides ear A32 and presss from both sides the outer of ear B33
Diameter is also equal to the outer diameter of hollow sleeve 22.
Shown in as shown in Figure 2, Figure 3 and Figure 4, input shaft 24, which slides, to be pierced by the end of flexible bearing 4 and is equipped with fixing piece 23, will in
Empty set 22 is bonded with the end face of folder ear A32, then inwardly turns fixing piece 23 so that hollow sleeve 22 respectively with hollow jack
21 and folder ear A32 is compressed.
On the basis of above scheme, input shaft 24 is using bolt, and fixing piece 23 is using nut.
Based on the above technical solution, pressure pump 11 is using hydraulic hand-pump, and communicating pipe 12 is using liquid
Pressure pipe.
The course of work of the utility model: bolt is pierced by from the circular hole in hollow jack 21, in hollow jack 21
Lower section successively wear hollow sleeve 22, the flexible bearing 4 in Ji Shouliu arm 3 again.Then, manually by hollow sleeve 22 and folder ear
The end face of A32 is bonded, then inwardly turns nut, so that hollow sleeve 22 is compressed with hollow jack 21 and folder ear A32 respectively.Most
Afterwards, hydraulic hand-pump is pressed, hollow jack 21 is pressed to hollow sleeve 22, so that hollow jack 21 presses hollow sleeve 22
It is moved down with by stream arm 3, so that flexible bearing 4 is detached from folder ear A32 certain distance, to reach job state.
Embodiment described above only expresses one or more embodiments of the utility model, describes more specific
With it is detailed, but it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for this field
Those of ordinary skill for, without departing from the concept of the premise utility, various modifications and improvements can be made, this
Belong to the protection scope of the utility model.
