Specific implementation mode
The technique effect of the design of the present invention, concrete structure and generation is carried out below with reference to embodiment and attached drawing clear
Chu is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair
Bright a part of the embodiment, rather than whole embodiments, based on the embodiment of the present invention, those skilled in the art are not being paid
The other embodiment obtained under the premise of creative work, belongs to the scope of protection of the invention.In addition, be previously mentioned in text
All connection/connection relations not singly refer to component and directly connect, and refer to that can be added deduct according to specific implementation situation by adding
Few couple auxiliary, to form more preferably coupling structure.Each technical characteristic in the invention, in not conflicting conflict
Under the premise of can be with combination of interactions.
Referring to Fig.1, a kind of nuclear power fire resisting damper Electric Actuator dismantles mounting tool, including limit bottom plate 1, the limit bottom
The top side of plate 1 is provided with limit fixed plate 2, top side setting of the limit fixed plate 2 far from the limit bottom plate 1
Power apparatus is unloaded, lower part side of the limit fixed plate 2 far from the limit bottom plate 1 is vertically arranged with two pieces of side limiting plates 3,
Gap is provided between two pieces of side limiting plates 3, the lower part of the limit bottom plate 1 is fixedly connected with bracket base.
It can be seen from the above, the present invention provides a kind of nuclear power fire resisting damper Electric Actuator dismounting mounting tool, include limit
The top side of bottom plate 1, limit bottom plate 1 is provided with limit fixed plate 2, top side of the limit fixed plate 2 far from limit bottom plate 1
It is provided with and unloads power apparatus, the lower part of limit bottom plate 1 is fixedly connected with bracket base, is carried out to whole device by bracket base steady
Gu it is fixed, when needing to install or remove the Electric Actuator of nuclear power fire resisting damper, entire fire resisting damper can be mounted on limit
On bottom plate 1, it is fixedly connected by buckle or bolt, screw, by the fixation of tooling, can be facilitated to fire resisting damper anywhere
Installing and dismounting is carried out, unloading power apparatus and can play auxiliary to the installing and dismounting of Electric Actuator in fire resisting damper in fixed plate 2 is limited
Effect, due to there is compressed spring in Electric Actuator, when especially dismantling the spring, if accidentally dismantled, it is easy to due to
The elastic force of spring and maintenance personal is damaged, at this point, this can effectively be solved the problems, such as by unloading power apparatus, nuclear power fire resisting damper is fixed on
Limit bottom plate 1 side, and fixed by limiting the limit of fixed plate 2, the Electric Actuator in fire resisting damper two pieces of side limiting plates 3 it
Between gap below, the top plate that is connect with spring when being dismantled to the spring in Electric Actuator, in Electric Actuator can be
Up and down in gap between two pieces of side limiting plates 3, side limiting plate 3 can limit the up and down of top plate, avoid it
Offset improves safety when being dismantled to spring, it is preferred that the center line of spring and the line of symmetry of two pieces of side limiting plates 3 do not weigh
It closes, under the dismounting for unloading power apparatus, the eccentric force that the elastic force of spring generates top plate makes top plate be not easy in side limiting plate 3
It shifts under limit, stability is more preferable when dismounting, by two pieces of side limiting plates 3 to the top plate of connecting spring in Electric Actuator
The case where being limited, and gradually removed the pretightning force of spring using power apparatus is unloaded, avoiding the pop-up of spring moment, can be to whole
Body structure carries out effective protection, it is ensured that maintenance personal escapes injury, and is also effectively guaranteed mating to fire resisting damper inside nuclear power station
Electric Actuator replacement timeliness in terms of demand, while also to a certain extent by the maintenance process mark of Electric Actuator
Standardization, the so just significantly more efficient reasonability that ensure that Electric Actuator maintenance process and safety, therefore, the present invention can have
Effect improves the efficiency of installing and dismounting fire resisting damper, and provides safety guarantee, knot to the Electric Actuator installing and dismounting in fire resisting damper
Structure is secured, using easy, stable, safe and reliable.
