Abstract
The utility model discloses a motor fan detaching tool including a mandril and a pulling sleeve with a tubby structure; a hemicycle ring is arranged at the front end of the pulling sleeve; an end part of the hemicycle ring is bent inwards to form a ring-shaped lug boss; an axial threaded hole is formed at the rear end of the pulling sleeve; external threads are formed at the mandril and screwed into the threaded hole, so that the mandril can be propped against a motor shaft of a fan to be detached. The utility model can solely finish the detachment of the motor fan under the condition of operation by only one person, the detachment time is greatly shortened to only 3-5 minutes, the working efficiency is improved, the motor shaft is not be knocked any more in detachment, and no damage is caused on the motor shaft.
Description
Technical field
The utility model relates to a kind of plant equipment extracting tool, particularly a kind of electric motor fan extracting tool.
Background technology
Electric motor fan is the motor radiating parts, can have a strong impact on the normal operation of motor after the damage, can cause burn-down of electric motor sometimes even also.The maintenance of daily electric motor fan is particularly important to the normal operation of motor.Fan is to install by the mode that key cooperates, and has the characteristics of slight interference fit.In the prior art, fan is disassembled employing from motor shaft hold fan, hit the method for motor shaft again with external force in the opposite direction with external force.When dismantling, this method for dismounting must two people's cooperations finish waste of manpower; And the take-down time is longer, generally needs more than 1 hour time, and operating efficiency is extremely low; Simultaneously,, can cause damage, cause the loss that there is no need motor shaft because the instrument of grade is impacted in the common employing of impacting of motor shaft.
Therefore, need a kind of extracting tool of electric motor fan, can the independent operation of people finish dismantlement work, the take-down time is short, increases work efficiency, and motor shaft is not caused damage.
The utility model content
In view of this, the purpose of this utility model provides a kind of electric motor fan extracting tool, can a people finish dismantlement work separately, shortens the take-down time greatly, increases work efficiency, and does not need to knock motor shaft during dismounting, motor shaft is not caused damage.
Electric motor fan extracting tool of the present utility model, comprise push rod and help pull a cart, described helping pull a cart is barrel-like structure, the front end of helping pull a cart is a semicircular ring, the inside bending in semicircular ring end forms annular boss, the rear end of helping pull a cart is provided with the axial thread hole, and push rod can withstand the motor shaft of waiting to tear open fan after external screw thread being set and screwing in screwed hole.
Further, described helping pull a cart comprises overcoat and interior cover, and described interior cover front end is a semicircular ring, and back end outer circumference is provided with external screw thread; The overcoat rear end is provided with the axial thread hole that is rotary with push rod, the internal thread that the setting of overcoat front end inner peripheral surface matches with interior cover external screw thread;
Further, described overcoat back-end closure forms the cover end, and the axial thread hole that is rotary with push rod is arranged on the cover end;
Further, can to withstand an end of motor shaft be needle-like to described push rod.
The beneficial effects of the utility model are: electric motor fan extracting tool of the present utility model, the structure that adopts push rod and help pull a cart, utilization is helped pull a cart and the relative motion of push rod, fan is left behind from motor shaft, can finish dismantlement work separately under the situation of people's operation, shorten the take-down time greatly, only need 3-5 minutes, increase work efficiency, do not need to knock motor shaft during dismounting, motor shaft is not caused damage; Helping pull a cart is divided into interior cover and overcoat two parts, can regulate the push rod travel distance by the screwing length between the overcoat in regulating, and makes adaptability enhancing of the present utility model; The push rod front end is a needle-like, is beneficial to locate after push rod withstands motor shaft, skids when avoiding operating.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the utility model structural representation;
Fig. 2 is interior nested structure schematic diagram.
The specific embodiment
Fig. 1 is the utility model structural representation, Fig. 2 is interior nested structure schematic diagram, as shown in the figure: electric motor fan extracting tool of the present utility model, comprise push rod 1 and help pull a cart 2, helping pull a cart 2 comprises the overcoat 21 of barrel-like structure and the interior cover 22 of barrel-like structure, and interior cover 22 front ends are semicircular ring, and the inside bending in semicircular ring end forms annular boss 3, during use, annular boss 3 can block the annular boss on the axle sleeve 6 of fan 4; Interior cover 22 back end outer circumference are provided with external screw thread, and overcoat 21 front end inner peripheral surfaces are provided with internal thread, and interior cover 22 and overcoat 21 pass through threads engaged; Overcoat 21 back-end closures form the cover end, and the cover end is provided with the axial thread hole, and push rod 1 is provided with external screw thread and screws in screwed hole, can withstand the motor shaft 5 of waiting to tear open fan 4; The end that push rod 1 can withstand motor shaft 5 is an acicular texture, is beneficial to the end of withstanding motor shaft 5 and can carries out located lateral.
Certainly, 2 structures that are not limited to present embodiment of helping pull a cart also can be the structures of one, can both reach goal of the invention.
When the utility model uses, interior cover 22 and overcoat 21 pass through threads engaged, interior cover 22 is enclosed within on the axle sleeve 6 of fan 4, the boss 3 of cover 22 is stuck in the boss on the axle sleeve 6 in making, push rod 1 is screwed in the screwed hole of overcoat 21 and withstands motor shaft 5, by revolving push rod 1 pulling force is passed to axle sleeve 6, fan 4 is left behind from motor shaft.Whole process is simple to operation, and a people can finish, and shortens the take-down time greatly, only needs to finish in 3-5 minutes, increases work efficiency.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
