Notations for reference numerals: 1-fixing nut, 2-double-end screw rod, 3-limiting block, 4-ram and 5-slide rod.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
Please refer to fig. 1 and 2, in an embodiment of the present invention, an extractor for a driven gear mechanism of an overspeed parking apparatus, includes a fixing portion for fixing the driven gear mechanism and an extracting portion for extracting the driven gear mechanism from the overspeed parking apparatus, the fixing portion includes a stud 2 and two fixing nuts connected to two ends of the stud 2 through threads, the stud 2 has a diameter of 30mm and a length of 350mm, the extracting portion includes a sliding rod 5, the sliding rod 5 has a length of 500mm, a ram 4 is slidably mounted on the sliding rod 5, the ram 4 is of a double-cone structure, two ends of the sliding rod 5 are both provided with a stopper 3 for preventing the ram 4 from slipping, and the fixing portion and the extracting portion are assembled into a whole through threads.
When the double-head screw rod pulling device is used, the fixing nuts 1 at two ends of the double-head screw rod 2 are firstly screwed off, then the double-head screw rod 2 penetrates through the driven gear mechanism and the fixing nuts 1 are sequentially screwed, so that the double-head screw rod 2 and the driven gear mechanism are in a mutually fixed state, then the pulling part and the fixing part are screwed and assembled into a whole and the ram 4 is stirred, and the driven gear mechanism is pulled out from the overspeed parking device body by utilizing the instant movement of the ram 4 on the sliding rod 5 to generate pulling force.
Example 2
The embodiment of the utility model provides a different from embodiment 1 lies in, and is further, for the convenience of stirring the ram 4, evenly be equipped with anti-skidding line on the ram 4, anti-skidding line can effectively increase the frictional force between staff and the ram 4, prevents to take off the hand when stirring ram 4, and it is more convenient to use.
The utility model discloses a theory of operation is: the utility model discloses when using, unscrew the fixation nut 1 at 2 both ends of double-end lead screw earlier, then pass double-end lead screw 2 from the internal portion of driven gear mechanism and screw fixation nut 1 in proper order thereby make double-end lead screw 2 and driven gear mechanism be the mutual stationary state, then will extract the part and screw the equipment as an organic whole with the fixed part and stir ram 4, utilize ram 4 to produce the extraction force in the twinkling of an eye on slide bar 5 and follow the internal extraction of overspeed parking device with driven gear mechanism, moreover, the steam generator is simple in structure, convenient and practical.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
