First limit base and the second limit base are each attached on base 1, and the first limit base and the second limit base are usually steel
Ferrum component, can be welded on base 1 by way of full weld.Between first limit base and the second limit base, there is gap.Need
It is noted that hydraulically extensible part 2 includes cylinder body and expansion link, the end of cylinder body is referred to as the positioning end of hydraulically extensible part, stretches
The end of contracting bar is referred to as telescopic end.In the application, the positioning end of hydraulically extensible part 2 and the spacing cooperation of the first limit base, hydraulic pressure
The telescopic end of extensible member 2 is towards the second limit base.The telescopic end of hydraulically extensible part 2 is provided with apical axis 3.For the ease of driving apical axis
3 stable moving ahead it is preferred that the telescopic end of hydraulically extensible part 2 is provided with Blind locating holes, one end of apical axis 3 is arranged on positioning blind
Kong Zhong, the other end stretches out, as working end.
In the application, apical axis 3 extends towards the second limit base, and is formed for clamping dummy bar and the second limit base between
8 grasping part, when dismantling dummy bar 8, dummy bar 8 can be placed in grasping part for operator.Second limit base
There is the avoidance gap 4 of the connecting shaft for avoiding dummy bar 8, apical axis 3 is used for positioned opposite with connecting shaft, and can stretch with hydraulic pressure
The stretching, extension of contracting part 2 and apply to make the power that it comes off to connecting shaft.
During using, dummy bar 8 is placed on by operator for dummy bar provision for disengagement disclosed in the present embodiment
So that the connecting shaft on dummy bar 8 is aligned with apical axis 3 between apical axis 3 and the second limit base, hydraulically extensible part 2 is then controlled to stretch
Exhibition, the stretching, extension of hydraulically extensible part 2 can drive apical axis 3 to push up to connecting shaft, and due to the opposite side of dummy bar 8, to be positioned second spacing
Seat, and, the second limit base position relative with the connecting shaft of dummy bar 8 is provided with avoidance gap 4, with hydraulically extensible part 2
Lasting stretching, extension, connecting shaft can be ejected from dummy bar 8 by apical axis 3, and then realize coming off of connecting shaft, finally realize dummy bar
8 dismounting.During whole operation, operator only needs to be in place dummy bar 8, and then manipulation hydraulically extensible part 2 is
Can, simple, convenient, labor intensity is relatively low, and meanwhile, this targetedly dismounting can be compared to by this artificial percussion apical axis
For, removal efficiency is higher.It can be seen that, dummy bar provision for disengagement disclosed in this utility model embodiment can solve to pass through at present to strike
Hit the apical axis problem larger to dismantle less efficient and labor intensity existing for connecting shaft.
Using provision for disengagement disclosed in the present application, connecting shaft is ejected by apical axis 3, and in whole process, connecting shaft stress is more equal
Even, secondary damage will not be produced to the other parts of dummy bar 8 simultaneously again, nor be easily caused connecting shaft and deform, because
This, provision for disengagement disclosed in the present application has higher Practical Performance.This provision for disengagement can be used for multiple times, and cost of manufacture is relatively
Low, it is possible to achieve repeatedly to dismantle, the cost performance of this provision for disengagement is higher.
Dummy bar provision for disengagement disclosed in the present application can include standby apical axis, many of standby apical axis, the length of every
Difference, is easy to during ejection connecting shaft, and operator changes the different apical axis of length and implements operation, and this can be further
Improve work efficiency, certainly, operator can using longer apical axis, by control the flexible stroke of hydraulically extensible part 2
Reach identical dismounting purpose.
The positioning end of hydraulically extensible part 2 can be connected on the second limit base, for example fixing, and this can improve hydraulically extensible
Stablizing of the telescopic end of part 2 is stretched out.But, for the ease of to replacing or the maintenance of hydraulically extensible part 2 it is preferred that hydraulically extensible
The positioning end of part 2 is positioned on the second limit base, that is, contacts with the second limit base positioning.For the ease of overhauling, again simultaneously
Guarantee the steady operation of hydraulically extensible part 2 it is preferred that the spacing cooperation of positioning end of the first limit base and hydraulically extensible part 2
Surface is provided with locating slot, the positioning end location fit of locating slot and hydraulically extensible part.In the application, hydraulically extensible part 2 is permissible

End plate and the positioning end location fit of hydraulically extensible part 2.The plate face of the two end plates of H profile steel 5 is towards the stretching, extension with hydraulically extensible part 2
Direction is consistent, and in such cases, H profile steel 5 can play more firm supporting role.Specifically, H profile steel 5 can be H700*
300 shaped steel.
In order to improve the intensity of whole dismounting device, it is to avoid hydraulically extensible part 2 passes through apical axis 3 to be led to dummy bar 8 force
Second limit base Joint failure it is preferred that provision for disengagement disclosed in the present embodiment can also include reinforcement 6, the one of reinforcement 6
End is fixed on the first limit base, and the other end is fixed on the second limit base.Preferably, reinforcement 6 is many, discrete connection
In the different parts of the first limit base and the second limit base, play the purpose of balanced hardening.Reinforcement 6 can adopt steel plate, example
As the steel plate that 70mm is thick.
The version of the second limit base has multiple, as long as having avoidance gap 4, it is fixed to be also secured on base 1 to play
Position dummy bar 8 acts on.Referring again to Fig. 1, the present embodiment discloses a kind of the second limit base of concrete structure, disclosed
Second limit base includes many keepers 7, many keeper 7 Discrete Distribution, and is each attached on base 1.Adjacent two are fixed
The adjustment difficulty to dummy bar 8 position for the operator all can be easy to as avoiding gap 4 in space between the part 7 of position.Keeper
Specification identical steel plate can be adopted, the thick steel plate of such as 100mm.
Herein, each preferred version only emphasis describe different with other schemes, as long as each preferred version
Do not conflict, can combination in any, the embodiment being formed after combination also within category disclosed in this specification it is contemplated that
Text is succinct, is individually described with regard to no longer formed to combination embodiment herein.
