People hold and control the handle with hands, the other end of the handle is directly sleeved on a to-be-detached screw nut, and the main internal structure of a box body is manufactured by adopting the principle of a secondary planet gear speed reducer.

Description

Nut remover

Affiliated technical field

The utility model relates to a kind of nut remover, can dismantle the nut of plurality of specifications, especially is in the dismounting of the nut in the adverse circumstances such as tunnel, down-hole (colliery).

Background technology

At present, what known nut dismounting was adopted generally all is lever principle, spanner for example, such dismounting is generally used in needs that strength is less, working environment is local preferably, but for the nut that makes moist, bearing capacity is bigger etc. is out of shape or gets rusty owing to extraneous factor, just remove and relatively require great effort, not quick detachable.

Summary of the invention

In order to solve the nut dismounting under the various situations with less power, the utility model provides a kind of nut remover, this nut remover goes for the nut of all size, and be convenient to nut dismounting under the various abominable bad borders condition such as down-hole, be convenient for carrying, easy operating.

The technical scheme that its technical problem that solves the utility model adopts is: input unit adopts handle (being similar to the device of steering wheel), output device adopts sleeve, between handle and sleeve, adopted the secondary planet wheel decelerator, handle is connected with decelerator with input, output shaft respectively with sleeve, this device utilizes principle (meshing by gear wheel and pinion of decelerator, when reducing rotating speed, increase torque), thereby utilize less input torque to obtain bigger output torque, for the nut of different model, also be equipped with the sleeve of corresponding model.

The purpose of this utility model and to solve its technical problem be to adopt following technical scheme to realize.According to the nut remover that the utility model proposes, its characteristics are: in casing, handle is connected with power shaft by key, power shaft is connected with a high speed grade planetary gear by meshing mode with high speed level sun gear, high speed level sun gear by key, the level planetary gear is installed on the high speed level planet carrier by axle at a high speed, utilize axle that high speed level planet carrier is connected with the axle of slow speed turbine stage sun gear again, its axis links together by a bolt and a high speed level planet carrier, the transmission of slow speed turbine stage is with level is identical at a high speed, and final output shaft also is to utilize the mode of key to be connected with sleeve.

The purpose of this utility model and solve its technical problem and can also be further achieved by the following technical measures.

Utilize axle, nut to be connected between the aforesaid nut remover, wherein said high speed level sun gear and slow speed turbine stage sun gear.

Utilize floating structure to be connected between the aforesaid nut remover, wherein said high speed level sun gear and slow speed turbine stage sun gear.

The beneficial effects of the utility model are, go for the dismounting of multiple model nut, can solve when nut owing to have micro-strain or make moist and get rusty etc. former thereby cause dismantling situation of difficult.

Below in conjunction with drawings and Examples the utility model is further specified.
