Abstract
The utility model discloses a hydraulic turbine activity guide vane arm dismouting device comprises screw rod, support frame, a pad, bolt, activity guide vane arm, activity stator pivot. The utility model has the advantages that hydraulic turbine activity guide vane arm dismouting device's structural rigidity is strong, warp for a short time during the atress, and it is big to bear the load, and the structure atress is reasonable to can change main atress part, do benefit to repetitious usage many times. The utility model discloses when can be applied to hydroelectric set installation and maintenance, the installation and the dismantlement of hydraulic turbine activity guide vane arm.
Description
Technical Field
The utility model relates to a hydraulic turbine field especially relates to a hydraulic turbine activity guide vane arm dismouting device.
Background
The movable guide vane of the water turbine runs in water for a long time, and the movable guide vane arm is connected with the pivot of the movable guide vane in a close fit way, so that, along with the increase of the operation period in water, the movable guide vane arm and the movable guide vane pivot are easy to generate surface corrosion phenomenon, which causes the disassembly process of the movable guide vane arm to be difficult, in addition, in the process of installing the movable guide vane of the water turbine, in order to ensure the level of the movable guide vane arm and the guide vane connecting plate so as to ensure the synchronous control of the movable guide vane, when the tool is not used, the adjustment can not be carried out by knocking or other methods, the guide vane arm dismounting device can carry out axial force transmission through threads, the guide vane arm is stressed uniformly in the dismounting process, on one hand, the guide vane arm is convenient to dismount from the guide vane pivot, on the other hand, the movable guide vane arm and the guide vane connecting plate can be mounted synchronously and horizontally, and therefore normal opening and closing actions of the movable guide vane can be guaranteed.
At present, the design structure of guide vane arm dismouting device carries out the thread reaming at activity guide vane pivot end to the screw thread of activity guide vane number axle head bears the load, carries out the dismantlement of guide vane arm, installs many times and dismantles the in-process, easily causes the damage of activity guide vane pivot end screw thread, is unfavorable for repetitious usage, and is very inconvenient to the installation and dismantlement moreover, can't satisfy the operation requirement.
Disclosure of Invention
In view of this, the utility model aims at providing a hydraulic turbine activity guide vane arm dismouting device compares hydraulic turbine activity guide vane arm dismouting device's primary structure type, the utility model has the advantages that, structural rigidity is strong, and it is little to warp during the atress, can bear the load big, and the structure atress is reasonable to can change main stress component, do benefit to repetitious usage many times. The technical scheme of the utility model is that: the movable guide vane device comprises a screw, a support frame, a support pad, a bolt, a movable guide vane arm and a movable guide vane pivot, wherein the screw is connected with the support frame in a threaded manner, the support pad is connected with the movable guide vane pivot in a threaded manner, the support frame is fixedly connected with the movable guide vane arm in a bolt manner, the movable guide vane arm is connected with the movable guide vane pivot in a tight fit manner, the screw is tightly pressed against the support pad, and when the screw moves downwards in a threaded manner, the support frame drives the movable guide vane arm to move upwards by the bolt, so that the movable guide vane arm is detached.
In the above device for mounting and dismounting the movable guide vane arm of the water turbine, the support frame is a whole circular plate.
In the device for dismounting and mounting the movable guide vane arm of the water turbine, the support pad is of a detachable structure.
In the device for dismounting and mounting the movable guide vane arm of the water turbine, the bolt is of a jackscrew structure, and the outer diameter of the bolt is not less than M12.
Technical effects
Compared with the prior art, the beneficial effects of the utility model are that:
1. the support cushion threaded structure bears tensile load, and is favorable for multiple mounting and dismounting of the movable guide vane arm.
2. The support pad structure can be made of a material with a higher strength grade relative to the movable guide vane, and can be replaced when the support pad is damaged after being used for many times, so that the movable guide vane is protected.
3. The movable guide vane arm dismounting device is small in stress deformation, large in bearable load and reasonable in structural stress, can ensure that the movable guide vane arm dismounting device meets the use requirement, and strengthens the stability of the movable guide vane arm dismounting device so as to be convenient to use repeatedly.
