Scope.
Please as shown in Figures 1 to 4, the embodiment of the present invention provides a kind of lowering or hoisting gear, and the lowering or hoisting gear is used for heating chamber
Interior material is moved in quenching chamber 1, including drive mechanism 2 and Tuo Wu mechanisms 3, and Tuo Wu mechanisms 3 are arranged in quenching chamber 1 and energy
Enough vertical shifts, the shape phase of the shape of cross section of Tuo Wu mechanisms 3 and the through hole 41 in the heated door 4 of heating chamber in quenching chamber 1
Matching, and the top of Tuo Wu mechanisms 3 is relative with through hole 41, so that Tuo Wu mechanisms 3 can enter heating when heated door 4 is closed
Room, drive mechanism 2 is used to drive the vertical shift in quenching chamber 1 of Tuo Wu mechanisms 3.
Material lifting device provided in an embodiment of the present invention, compared with prior art, due to the cross section of Tuo Wu mechanisms 3
Shape matches with the shape of through hole 41 in heated door 4, and the top of Tuo Wu mechanisms 3 is relative with through hole 41 so that Tuo Wu mechanisms 3
Heating chamber can be entered when heated door 4 is closed, Tuo Wu mechanisms 3 enter back into heating chamber after being opened without waiting for heated door, therefore,
Material lifting device provided in an embodiment of the present invention, shortens after heated door opening, the material in heating chamber is moved to and quenched
The fiery indoor time, it is to avoid radiated by the material of oven heats before quenching chamber is entered overlong time, so as to cause thing
Expect that the temperature of different parts is uneven so that material performance is reduced.
Wherein, Tuo Wu mechanisms 3 include support thing part 31 and support thing base 32, and support thing base 32 is fixedly mounted on support thing part
The shape of 31 bottom, the shape of cross section of support thing part 31 and the through hole 41 in the heated door 4 of heating chamber matches, and support thing
The top of part 31 is relative with through hole 41 so that support thing part 31 can enter heating chamber when heated door 4 is closed, and hold in the palm thing base
32 are connected with drive mechanism 2.
In the embodiment of the present invention, in order that Tuo Wu mechanisms 3 can vertical shift be more steady in quenching chamber 1, thing is being held in the palm
Guiding mechanism 5 is also equipped with base 32, the vertical shift in quenching chamber 1 play the guiding role guiding mechanism 5 to Tuo Wu mechanisms 3.
Wherein, guiding mechanism 5 includes guide rail 51 and slide unit 52, and slide unit 52 is fixedly mounted on support thing base 32
On, the guide rail (51) is fixedly mounted on the bottom of the quenching chamber (1) by guiderail base (8), and passes through support member
(7) on the inwall fixed to the quenching chamber (1), slide unit 52 coordinates so that slide unit 52 can be in guide rail with guide rail 51
Slided vertically on 51.
When the vertical shift in quenching chamber 1 of Tuo Wu mechanisms 3, the slide unit 52 being fixedly mounted on support thing base 32 exists
Slided on guide rail 51, the limitation due to guide rail 52 to the moving direction of slide unit 52, therefore, make the slip vertically of slide unit 52,
So that the moving direction for the support thing base 32 being fixedly connected with slide unit 52 is limited in vertical shift, Shi Tuo things mechanism 3
Vertical shift is more steady.
It is of course also possible to be that guide rail 51 is fixedly mounted on support thing base 32, slide unit 52 is fixedly mounted on quenching chamber 1
Inwall on.
Slide unit 52 in the embodiment of the present invention is preferred to use pulley, and guide rail 51 is preferred to use guide groove.
Certain slide unit 52 can also be sliding block, and guide rail 51 is guide groove.
Certain slide unit 52 can also be provided with the fixed block of chute, and guide rail 51 is the gib block for being provided with projection,
Projection on gib block is with the chute on fixed block to cooperation.
Drive mechanism 2 in the embodiment of the present invention includes driving part 21, driving wheel 22, driven pulley 23 and drive disk assembly
24, wherein, drive disk assembly 24 is set in driving wheel 22 and on driven pulley 23, driving part 21 is connected to drive master with driving wheel 22
Driving wheel 22 is rotated, and Tuo Wu mechanisms 3 are fixedly connected with drive disk assembly 24.
When driving part 21 works, the driving driving wheel 22 of driving part 21 is rotated, because rotatable parts 24 are set in master
On driving wheel 22 and driven pulley 23, therefore, make drive disk assembly 24 driving wheel 22 while driven pulley 23 is rotated also together with rotate.
Because Tuo Wu mechanisms 3 are fixedly connected with drive disk assembly 24, therefore, drive disk assembly 24 rotate during, Tuo Wu mechanisms 3 with
The point fixed with drive disk assembly 24 is moved with drive disk assembly 24.
More specific, driven pulley 23 is fixedly mounted on bottom or the side wall of quenching chamber 1, and the driving wheel 22 fixes peace
Mounted in the top of quenching chamber 1 or side wall so that being set in driven pulley 23 can be vertical with the drive disk assembly 24 on driving wheel 22
Set.
In the embodiment of the present invention, drive mechanism 2 also includes tension part 25, and tension part 25 is connected use with drive disk assembly 24
In the Zhang Jindu of regulation drive disk assembly 24.
Because drive mechanism 2 is during work, and the Zhang Jindu of drive disk assembly 2 not enough, can influence drive mechanism 2 to drive
The effect of the vertical shift of Dong Tuo things mechanism 3, therefore, sets tension part 25 to adjust the Zhang Jindu of drive disk assembly 24, can make drive
The vertical shift effect of the driving Tuo Wu of motivation structure 2 mechanisms 3 reaches most preferably.
During the present invention is implemented, driving wheel 22 is preferred to use sprocket wheel with driven pulley 23, and drive disk assembly 24 is preferred to use chain.
Tension part 25 is preferred to use tensioning wheel, and certain tension part 25 can also be the miscellaneous part of tension.
