Abstract
The invention relates to a gas-liquid linked dismounting device of fan impellers, mainly comprising a stand, a hydraulic system, a pneumatic system, an electrical control system, a dismounting operation device, a lifting table and a rotating platform. The gas-liquid linked dismounting device is characterized in that impeller shaft sleeves are clamped by adopting the hydraulic system, a motor shaft is impacted by the pneumatic system for the gas-liquid linked dismounting of the fan impellers, a jaw part is provided with teeth and is locally quenched, the lifting table adopts a scissors fork type structure and has a high lifting speed and a low lifting speed, wherein the low lifting speed is used for dismounting alignment. When the impellers at both ends of a fan are dismounted, the fan is placed on the platform, and then the two impellers can be rapidly dismounted by utilizing the rotation and the lifting of the platform; and a clamp head is pushed to clamp the impeller shaft sleeves by an oil cylinder, an impacting mechanism carries out flexible impacting and loosening on the motor shaft, an uploading air cylinder generates static thrust for the impact mechanism and applies the static thrust to the motor shaft, and the motor shaft is pushed out of the impeller shaft sleeve under the actions of a dynamic load and a static load. The invention can prevent the fan impellers, the impeller shaft sleeves and the motor shaft from being damaged when the fan is dismounted, thereby greatly improving a dismounting effect.
Description
Technical field
The present invention relates to Fan Equipment, be specially a kind of gas-liquid linked dismounting device of fan impellers of the dismounting that is applied to centrifugal blower fan blade wheel.
Background technology
All comprise impeller in the existing centrifugal blower, be easy to impeller is made dirty in the time of blower fan work, influenced the service behaviour of centrifugal blower, also damage impeller easily simultaneously, need regularly pull down impeller and clean maintenance.
In the centrifugal blower maintenance, the dismounting of centrifugal blower fan blade wheel is an important service work.Because the structure of centrifugal blower fan blade wheel and axle sleeve thereof is special, can not adopt and draw agate to carry out impeller demolition.Simultaneously, because the withdrawal space of impeller is limited, contraposition was time-consuming when simple and easy anchor clamps such as employing gripping mechanism carried out impeller demolition, removal efficiency is low, and adopts artificial unloading's method promptly to knock impeller sleeve with iron staff or iron hammer from a side of impeller, has both wasted time and energy, cause draught fan impeller, motor shaft to damage again easily, even cause scrapping of whole blower fan, so present never having is suitable for impeller disassembling device efficiently.For the centrifugal blower that gets rusty in impeller sleeve and motor shaft junction, more there be not an effective method for dismounting of cover and an extracting tool.
Summary of the invention
The object of the present invention is to provide a kind of gas-liquid linked dismounting device of fan impellers, to solve the deficiency in the background technology.
A kind of gas-liquid linked dismounting device of fan impellers, by frame, hydraulic system, pneumatic system, electric-control system, the dismantlement work device, lifting platform, revolving dials etc. are partly formed, adopt the hydraulic clamp impeller sleeve, the gas-liquid linked mode of Pneumatic immpacting motor shaft is dismantled draught fan impeller, the chuck of dismantlement work device adopts T10 tool steel, associated jaw portion band tooth and selective hardening are handled, lifting platform adopts the scissors fork structure, has height two-stage rising or falling speed, low speed is used to dismantle contraposition, when dismantling blower fan two ends impeller, blower fan is placed on the platform, utilizes the revolution of platform, lifting, two impellers of quick release.One cover chuck can adapt to the centrifugal blower fan blade wheel dismounting of impeller sleeve diameter in certain limit, and chuck can be changed fast simultaneously, to adapt to the centrifugal blower fan blade wheel dismounting of wider impeller sleeve diameter.
In the present invention, oil cylinder promotes chuck and clamps impeller sleeve, and it is loosening that beater mechanism is implemented soft impulse to motor shaft, adds carrier gas cylinder impact mechanism and produces static thrust, and be applied on the motor shaft, and motor shaft is pushed out impeller sleeve under the effect of dynamic load and static load.
In the present invention, described blower fan is placed on the platform, can realize revolution, the lifting of blower fan, contraposition when being convenient to dismantle, and conveniently turn around to dismantle two impellers.
For guaranteeing the validity of gas-liquid linked dismounting device of fan impellers work; must carry out the optimal design of master-plan, structural strength analysis, airdraulic parameter matching design, Optimal Structure Designing and the flexible pneumatic impact parameter of this device; in addition; this device should have perfect protective device; when maloperation, can not cause damage to equipment; personnel are damaged, and this device answers adaptability strong, can adapt to the draught fan impeller dismounting of different sizes.
Beneficial effect:
Gas-liquid linked dismounting device of fan impellers of the present invention has been broken through traditional dismounting theory, theoretical and the integrated control theory of pneumoelectric liquid of applied aerodynamics, adopt the gas-liquid linked method for dismounting of hydraulic clamp impeller sleeve, Pneumatic immpacting motor shaft, can efficiently dismantle all kinds of centrifugal blower fan blade wheels, especially be suitable for the centrifugal blower that gets rusty in impeller sleeve and motor shaft junction, and causing the damage of draught fan impeller, impeller sleeve and motor shaft can prevent to dismantle fully the time, the dismounting effect is improved greatly.
