The greasy property of dynamic seat.
The pedestal is in a groove shape, and rotation seat is set on the base in the channel space at end and end face is empty without departing from flute profile thereon
Between, it is fixed with support element below rotation seat, the perforation passed through for support element is offered on pedestal.
The support element is the cylinder being fixed in the middle part of rotation seat, and transfer further includes for driving cylinder along itself axis
The actuator of line rotation.
The dottle pin is fixed on the slot bottom of pedestal.
The lower face shape of rotation seat is coincide with the upper surface shape of dottle pin to be adapted to.
The dottle pin is made of polytetrafluoro polyethylene.
The gantry crane of the utility model uses following technical scheme：
Gantry crane, including girder, supporting leg and cart, are provided with transfer, transfer between supporting leg and cart
Include the pedestal mounted on supporting leg lower end, the rotation seat mounted on cart upper end, rotation seat rolling assembling is on pedestal, rotation seat
Dottle pin is provided between the face that is rotatably assorted of pedestal, the greasy property of dottle pin is better than the greasy property of pedestal and rotation seat.
The pedestal is in a groove shape, and rotation seat is set on the base in the channel space at end and end face is empty without departing from flute profile thereon
Between, it is fixed with support element below rotation seat, the perforation passed through for support element is offered on pedestal.
The support element is the cylinder being fixed in the middle part of rotation seat, and transfer further includes for driving cylinder along itself axis
The actuator of line rotation.
The dottle pin is fixed on the slot bottom of pedestal.
The lower face shape of rotation seat is coincide with the upper surface shape of dottle pin to be adapted to.
The dottle pin is made of polytetrafluoro polyethylene.
The beneficial effects of the utility model are as follows：The utility model is arranged between rotation seat and the face that is rotatably assorted of pedestal
There is dottle pin, and the greasy property of dottle pin is better than the greasy property of pedestal and rotation seat, is equivalent to and increases between rotation seat and pedestal
If lubricant layer.So when turning to, rotation seat will not be in direct contact with pedestal, substantially reduce the frictional force of rotation vice division chief,
The durability that steering drag can not only be reduced, improve revolute pair is also beneficial to reduce the noise of rotation vice division chief, reduces to construct and make an uproar
Sound.
Description of the drawings
Fig. 1 is the structural schematic diagram of one embodiment of the gate-type machine heavy-duty machine of the utility model；
Fig. 2 is the partial enlarged view at II in Fig. 1.
Specific implementation mode
The embodiment of the gantry crane of the utility model：
The concrete structure of the gantry crane of the utility model is as depicted in figs. 1 and 2, including girder and is used to support girder
Supporting leg, ground beam 1 is provided between the supporting leg of girder the same side, the lower end of ground beam 1 is provided with for driving girder to walk
Cart 2.It is provided with transfer between ground beam 1 and cart 2.
Transfer includes the pedestal 4 for being fixed on 1 lower end of ground beam, the rotating part 3 on 2 free bearing 21 of cart and pushes away
The actuator 6 that dynamic rotating part 3 rotates.Rotating part 3 includes the rotation of plate-like of the rolling assembling in the channel space of pedestal 4
The support element 32 of seat 31, the bottom plate 33 and connecting bottom board 33 and rotation seat 31 that are fixed on free bearing 21.Pedestal 4 is in a groove shape, rotation
Seat 31 is disk-shaped and is rotatably dispose in the channel space 41 of pedestal 4, while the upper end of rotation seat 31 and the upper surface of pedestal 4 are neat
Flat setting.In other embodiments, the upper end of rotation seat can not also be flushed with the upper surface of pedestal, and be less than the upper of pedestal
End face, as long as it exposes not from the channel space of pedestal.
The perforation 42 passed through for support element 32 is further opened on pedestal 4.It is poly- that the slot bottom of channel space 41 is fixed with polytetrafluoro
Dottle pin 5 made of ethylene, a kind of polytetrafluoro polyethylene material minimum as friction coefficient in solid material, the spy of high lubrication
Property effectively reduces the frictional resistance between rotation seat 31 and pedestal 4.To increase the property of dottle pin 5 and 4 support rotation seat 31 of pedestal
Can, the upper surface shape of dottle pin 5 is coincide with the lower face shape of rotation seat 31 to be adapted to and the two is made to be bonded, the slot of channel space 41
Bottom is also the plane for being parallel to 31 lower face of rotation seat.In other embodiments, dottle pin can also be fixed on the lower end of rotation seat
On face；The material that dottle pin can also be better than pedestal and rotation seat greasy property by other greasy properties is made；The lower end of rotation seat
Face may not be plane, but the conical surface or curve, is adapted to as long as the shape of dottle pin upper surface is coincide with it.Certainly, this
When channel space slot bottom shape should also make adapt to change.
In the present embodiment, actuator 6 directly drive support element 32 rotate, so support element 32 be axis along the vertical direction
The cylinder of extension, and the rotation conllinear of its axis of rotation and rotation seat 31.In other embodiments, rotation seat and pedestal
Mating surface can also be curved surface, as long as rotation seat can rotate in pedestal.When the face of being rotatably assorted of the two can partly be wrapped
When wrapping up in rotation seat, rotation seat can also be arranged in the lower section of pedestal, and actuator can directly drive rotation seat and be turned round along itself at this time
Axis rotates, and support element can be set to other shapes.Certainly, support element more can be dispensed at this time.
The embodiment of the transfer of the utility model：
The specific knot of transfer in the concrete structure of the transfer of the utility model and the embodiment of gantry crane
Structure is identical, can refer to Fig. 1 and Fig. 2, and this will not be detailed here.
