Detailed description of the invention
As shown in Figures 1 to 4, the one of the present invention is used for the attaching/detaching apparatus of super-huge (partly) autogenous tumbling mill feeding seal ring,
Including dismounting support 1 and hydraulic brace mechanism 2, dismounting support 1 is for coordinating, in Appropriate application mill trunnion 20 with fork truck
The confined space, the sealing ring 7 departed from quill shaft 20 is transferred to suitable place smoothly, or sealing ring 7 is promoted to
Height corresponding with quill shaft 20, by rotating seal ring 7, makes the first bolt hole 22 on mounting flange 701 and quill shaft 20
On the second bolt hole 23 corresponding, it is simple to install.
The dismounting support 1 of the present invention includes base 3, is fixed on the pallet fork slot 4 bottom base 3, is fixed on base 3 top
Pulley bracket 5 and be arranged on pulley bracket 5 top and axially the most parallel with the length direction of described pallet fork slot 4 fixed pulley
6.Pallet fork slot 4 in the present embodiment is two channel-section steels being parallel to each other being welded on base 3 bottom surface, it is simple to the pallet fork of fork truck
It is inserted directly into, thus by forklift lifting whole dismounting support 1, the end face of base 3 is provided with two groups respectively with described two
The pallet fork fixed mechanism 24 that root channel-section steel is corresponding, often group pallet fork fixed mechanism 24 all include latch and two be parallel to each other and be fixed on
Angle steel on base 3, one end that two angle steel are positioned at the same side extends outside the end face of base 3, and offer in this end with
The corresponding jack of described latch, in using, after the pallet fork of fork truck inserts in described pallet fork slot 4, inserts latch in jack,
The vertical beam of fork of forklift truck is fixed in the space of angle steel, base 3 and latch composition, prevents whole dismounting support 1 at pallet fork
Upper slip.In the present embodiment, dismounting support 1 also includes two telescopic support arms 12, for support the inwall of sealing ring 7 with
Preventing sealing ring 7 from swinging and landing, two support arms 12 are separately positioned on the containing cavities 13 that dismounting support 1 base 3 both sides are arranged
In, and on support arm 12 and containing cavities 13, all offer hole, multiple corresponding location 14, support arm 12 by alignment pin 15 with receive
Receive chamber 13 and fix.Dismounting support 1 also includes two for preventing sealing ring 7 along gag lever post 16 in axial sliding of fixed pulley 6, institute
State two gag lever posts 16 to be respectively fixedly disposed at pulley bracket 5 top and be positioned at the both sides that described fixed pulley 6 is axial.Dismounting support 1
On fixed pulley 6 as the strong point of dismounting support 1 with sealing ring 7 inwall, the beneficially rotation of sealing ring 7, seal installing
During ring 7, more easily find the first bolt hole 22 on sealing ring 7 mounting flange 701 and the second bolt hole on quill shaft 20 accurately
The tram of 23, in the present embodiment, owing to sealing ring 7 volume is big, quality weight, the quantity of fixed pulley 6 is set to two, and two
Individual fixed pulley 6 is arranged in parallel, and for proof strength, the connecting portion at pulley bracket 5 and base 3 is provided with reinforcing plate 17.
Hydraulic brace mechanism 2 quantity in the present embodiment is four, is disposed in an evenly spaced relation in the Method for Installation of described sealing ring 7
On blue 701, and the hydraulic cylinder 10 of four described hydraulic brace mechanisms 2 all stretching by same Pump Control expansion link
Contracting.Each hydraulic brace mechanism 2 all includes fixed mount 9 and hydraulic cylinder 10, and described fixed mount 9 utilizes the mounting flange of sealing ring 7
Tight fixed bolt interface 11 on 701 is with female thread, thus is directly fixed by the mounting flange 701 of bolt 18 with sealing ring 7
Connecting, described hydraulic cylinder 10 is perpendicular to the mounting flange 701 of sealing ring 7 and arranges, and its cylinder body is connected by bearing pin with fixed mount 9,
The direction of fine-tuning expansion link, thus find the first bolt hole on mounting flange 701 accurately, its expansion link and this fixed mount 9 place
The first bolt hole 22 on the mounting flange 701 that position is corresponding is corresponding, and the end of expansion link connects also by helicitic texture to be had
One hard saddle 19, it is positioned in the second bolt hole 23, is used for bearing expansion link thrust and the weight of sealing ring 7.
In the implementation process of the present invention, when installing sealing ring 7, first dismounting support 1 is docked fixing, by close with fork truck
Seal ring 7 is placed on the fixed pulley 6 of dismounting support 1, and pull-out support arm 12 keeps small gap with the inwall of sealing ring 7, and passes through
Support arm 12 fixed by alignment pin 15, then by fork truck lifting sealing ring 7 to coaxial with mill trunnion 20, and rotary seal ring 7,
Make the first bolt hole 22 on sealing ring 7 mounting flange 701 corresponding with the second bolt hole 23 on the quill shaft 20 of mill
Closing securing member, complete to install.
When dismantling sealing ring 7, first mounting flange 701 four symmetric positions up and down of dismounting sealing ring 7 is tight
Firmware, and it is respectively mounted the hydraulic brace mechanism 2 of the present invention, make the hard saddle 19 of hydraulic cylinder 10 telescopic end through sealing ring 7
On the first bolt hole 22 enter in the second bolt hole 23 corresponding with this first bolt hole 22 on quill shaft 20, then will be equipped with
The fork truck of dismounting support 1 docks with sealing ring 7, is down to contact the inwall that sealing ring 7 is put by 6 liters of the fixed pulley of dismounting support 1, draws
The inwall going out support arm 12 and sealing ring 7 touches, and fixes support arm 12 by alignment pin 15, then removes all sealing rings 7
With the securing member of quill shaft 20, start hydraulic oil pump and make the expansion link of four hydraulic cylinders 10 synchronize elongation, make close by determining thrust
Seal ring 7 separates with quill shaft 20, falls within dismounting support 1, is transferred to suitable place finally by fork truck, completes sealing ring 7
Dismounting.
