Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model replacement steel support shaft force servo system servo segmented head.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
See Fig. 1, for replacing the support device of steel support shaft force servo system servo segmented head online, including there are two from
Locking-type hydraulic cylinder 3, pivot flange 4 and abutted flange 5, pivot flange 4 and abutted flange 5 include ring flange and interior
The neck tube connecting with ring flange is held, and the internal diameter of 4 neck tube of pivot flange is greater than the internal diameter of 5 neck tube of abutted flange, pivot flange 4
Ring flange is fixedly connected with the ring flange of 2 inner end of servo segmented head, on the ring flange of abutted flange 5 and 1 inner end of bracing members pipe
Ring flange is fixedly connected, and the cylinder body of two self-locking type hydraulic oil cylinders 3 is fixed on 8 side wall of foundation pit and is located at servo segmented head 2
Radial symmetric of the outer ring along servo segmented head 2, the ring flange of the piston rods of two self-locking type hydraulic oil cylinders 3 towards pivot flange 4
And the piston end of two self-locking type hydraulic oil cylinders 3 resists the ring flange of pivot flange 4, the neck tube of abutted flange 5 partially protrudes into
In the neck tube of pivot flange 5, abutted flange 5 is located on neck tube its outer wall outside pivot flange 4, the neck tube of pivot flange 4 is outside it
A circle bolt mounting base 6 is provided on the outer wall of end, and on abutted flange 5 bolt mounting base 6 bolt hole and supporting methods
The bolt hole of bolt mounting base 6 is concentric on orchid 4, and clamping screw 7 passes through the bolt hole and branch of bolt mounting base 6 on abutted flange 5
Abutted flange 5 is fixedly connected by the bolt hole of bolt mounting base 6 with pivot flange 4 on staying orchid 4.
Working principle of the utility model is:
When using support device for the first time, if encountering the ring flange and the unmatched situation of abutted flange 5 of bracing members pipe 1,
Abutted flange 5 is then only needed to change, support device rest part does not need to change；Abutted flange 5 and the inner end of bracing members pipe 1 are fixed
