Abstract
The improvement of plant equipment structure is the utility model is related to, in particular for the rod mill of sandstone processing.Sandstone processing rod mill improved structure includes the bull gear of rod mill, and bull gear has lightening hole, and its key technology is that the bull gear of rod mill is formed using two semicircle gear rings, and the interface of two semicircular gear ring is bolted assembly.The bull gear of rod mill is only changed to two semicircle gear rings by the utility model, is seemed and has simply been made slight improvement to the structure of rod mill, but but solves big problem in terms of the maintenance of rod mill, and maintenance step is simple, maintenance safety, time saving and energy saving.
Description
Technical field
The improvement of plant equipment structure is the utility model is related to, in particular for the rod mill of sandstone processing.
Background technology
At present, for the maintenance for the rod mill processed for sandstone, following steps are generally included：
1st, 25t cranes coordinate manual demolition rod mill little gear, drive gear guard, top bearing shell lid, feed hopper and front and rear charging
Device；2nd, hand fit extracts rod iron (about 18t) in rod mill machine out；3rd, 50t cranes, which coordinate, manually hangs out complete machine, and carries out support
Frame；4th, former bull gear is removed, renews bull gear；5th, 50t cranes coordinate and manually rod mill complete machine reposition；The 6th, rod milling is installed
Each annex of machine, loads new rod iron.It overhauls situation statistics such as following table：
Find out from upper table：Time-consuming, it is necessary to large-scale crane hoisting equipment is, it is necessary to artificial quantity is more with maintenance for this method,
The problems such as labor strength is big, cause the cost of overhaul too high, and operation area scope is with potential safety hazard.
The content of the invention
Problem to be solved in the utility model is insufficient aiming at more than and provides one kind and is easy to overhaul rod mill
Rod mill improved structure, contribute to rod mill time saving, laborsaving when being overhauled.Its technical scheme is as follows：
Rod mill improved structure is used in a kind of sandstone processing, includes the bull gear of rod mill, and bull gear has lightening hole, and it is closed
Key technology is the bull gear that rod mill is formed using two semicircle gear rings, and the interface of two semicircular gear ring is bolted spelling
Dress.
The quantity of bolt used is 6-10.
After rod mill structure is improved, rod milling machine overhauling situation statistics such as following table：
Find out from above-mentioned technical proposal and upper table, compared with prior art, the utility model has the advantage that as follows：
The bull gear of rod mill is only changed to two semicircle gear rings by the utility model, seems and simply the structure of rod mill is made
Slight improvement, but but solve big problem in terms of the maintenance of rod mill：
1st, after maintenance step, the utility model method dismounting rod mill little gear, drive gear guard, terminal pad, directly
Connect and cut open former bull gear, it is then half and half to remove former bull gear, then it is half and half load onto new bull gear, complete rod milling after fastening
The maintenance of machine；And after prior art removes rod mill little gear, drive gear guard, top bearing shell lid, feed hopper and front and rear feeder, need
Extract rod iron (about 18t) in rod mill machine out, hang out complete machine, and former bull gear could be removed after carrying out support frame, renew canine tooth
Circle, then also repositions rod mill complete machine, installs each annex of rod mill, loads new rod iron, could complete rod mill
Maintenance.Prior art maintenance step is too complicated, and the utility model method maintenance step is simple, maintenance safety.
2nd, in terms of maintenance used tool, only with 25t truck cranes, it is enough for the utility model, and finishing operation is pulled with lower moment of torsion again
Hand；And prior art be except with 25t truck cranes, will also use 50t truck cranes, steel wire rope, electric welding machine, channel-section steel, angle bar, these increasings
Add the cost of overhaul, also add unsafe factor.So the utility model method cost of overhaul is low.
3rd, in terms of the repair time, prior art is time-consuming 74 hours, 6 days；And the utility model is time-consuming 24 hours, 3 days, with showing
There is technology to compare, saved for 2/3 time, only with original 1/3 less than time, time cost save clearly, it is time saving, save
About cost.
4th, from the point of view of maintenance number, prior art needs 39 people, and the utility model only needs 20 people, has saved the people of half
Number, human cost is saved clearly, laborsaving, substantially reduces labor strength.
Brief description of the drawings：
Fig. 1, it is the utility model semicircle gear ring structure schematic diagram；
Fig. 2, it is second half knuckle-tooth coil structures schematic diagram of the utility model；
Fig. 3, it is the utility model use state figure.
Embodiment
Referring to Fig. 1~Fig. 3, rod mill improved structure is used in a kind of sandstone processing, includes the bull gear of rod mill, bull gear tool
There is lightening hole 1, its key technology is that the bull gear of rod mill, the interface of two semicircular gear ring 3 are formed using two semicircle gear rings 3
Assembly is connected by 6-10 bolt 2, bull gear requirement meets the requirement of former machine gear ring inner and outer diameter, and with all former machine gear rings
Modulus and the number of teeth are consistent.
The repair method of above-mentioned sandstone processing rod mill, its key technology are to comprise the following steps：
1st, 25t cranes coordinate manual demolition rod mill little gear, drive gear guard, terminal pad；
2nd, worn-out bull gear is segmented into two halves, removes half-turn original bull gear fixing bolt, half-turn original is hung out with 25t cranes
Bull gear；
3rd, aided in rotating rod mill with 25t cranes, remove remaining half-turn original bull gear fixing bolt, hung out with 25t cranes
Remaining half original bull gear；
4th, 25t cranes are in place by a semicircle gear ring 3, make the fixing bolt 2 of the semicircle gear ring (not tightening) in place；
5th, aided in rotating rod mill with 25t cranes, 25t cranes are in place by a remaining semicircle gear ring 3, allow the semicircle gear ring
Fixing bolt 2 it is in place (not tightening)；
6th, two semicircular gear ring 3 is docked, bolt 2 (optimal number 8) all fastens.
Claims (2)
1. rod mill improved structure is used in a kind of sandstone processing, including the bull gear of rod mill, bull gear has lightening hole (1), its
It is characterized in the bull gear that rod mill is formed using two semicircle gear rings (3), the interface of two semicircular gear ring (3) passes through bolt (2)
Connection is assembled.
2. rod mill improved structure is used in sandstone processing according to claim 1, it is characterized in that the quantity of bolt used is 6-10
.
