In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：
A kind of large-scale penstock stiffening ring installation special tool, including base plate, are installed on the walking of base plate lower end
Wheel, is fixedly installed in the slide rail in the middle part of base plate along base plate length direction, is vertically arranged on base plate, positioned at slide rail one end
Installing plate, be vertically arranged on base plate, positioned at the slide rail other end and the location-plate consistent with penstock inwall radian, it is sliding
Dynamic cooperation is installed on transfer arm on slide rail, cylinder body is fixedly connected with installing plate, piston rod is fixedly connected with transfer arm and with cunning
The parallel hydraulic jack of rail, and by regulating bolt be slidably installed on transfer arm, can be along transfer arm vertical sliding
The sliding block of regulation；The sliding block is located at the side that transfer arm closes on location-plate, and the sliding block side sets the neck of clamping stiffening ring.
Preferably, in addition to connection base plate and location-plate location-plate reinforcement.
Preferably, in addition to connection base plate and installing plate installing plate reinforcement.
Preferably, the road wheel uses self-locking universal wheel.
Preferably, the road wheel is connected by bolt with base plate.
Compared with prior art, the utility model has the following advantages that：
1st, the utility model has the characteristics that ingenious in design, simple structure, flexible and convenient operation.
2nd, the utility model is used for job site stiffening ring and the aid of the larger installation difficulty in steel pipe gap, practicality
By force, securely and reliably, it and can reuse, reduce cost, improve production efficiency.
3rd, the utility model is compared compared with traditional handicraft with U-typed annex spot welding, reduces the works such as welding, excision and polishing
Sequence, workload is greatly reduced so as to improve operating efficiency, while construction quality is ensured, shorten duration, economy effect
It is beneficial notable.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
