if you could suggest any tips or changes I might make them. But I am keeping Conkelldurr the same. I am 5-1 with this monotype team.

Here are two battles that I did with them.

Giga Drain runs off of Breloom's terrible Special Attack. Don't bother with it. Techniloom is the best set for it, at the moment, even though Poison Heal sets are viable too:
-Bullet Seed
-Mach Punch
-Low Sweep/Focus Punch
-Spore/Stone Edge
Nature: Jolly/Adamant
EVs: 4 HP/252 Atk/252 Spe
Item: Fighting Gem/Life Orb
Ability: Technician

Or
-Swords Dance
-Bullet Seed
-Mach Punch
-Spore
Nature: Adamant/Jolly
EVs: 4 HP/252 Atk/252 Spe
Item: Focus Sash/Fighting Gem
Ability: Technican

Or
-Bullet Seed
-Low Sweep/Force Palm
-Stone Edge
-Spore
Nature: Jolly
EVs: 4 HP/252 Atk/252 Spe
Item: Choice Scarf
Ability: Technician

Or
-Substitute
-Leech Seed
-Focus Punch
-Spore
Nature: Impish
EVs: 236 HP/252 Def/20 Spe
Item: Toxic Orb
Ability: Poison Heal

Or
-Substitute
-Focus Punch
-Spore
-Seed Bomb/Stone Edge/Facade
Nature: Adamant
EVs: 12 HP/252 Atk/244 Spe
Item: Toxic Orb
Ability: Poison Heal

I know you want to keep Conkeldurr the same, but here are my two cents on it regardless: Earthquake is a waste of Conkeldurr's coverage; it has redundant coverage with its Fighting STAB. Also, what's the point of using a Brave nature if you're barely investing in Conkeldurr's Attack?
-Bulk Up
-Drain Punch
-Mach Punch
-Ice Punch/Payback/Stone Edge
Nature: Adamant
EVs: 120 HP/252 Atk/136 SDef
Item: Leftovers
Ability: Guts

Or
-Drain Punch
-Mach Punch
-Facade/Payback
-Ice Punch
Nature: Adamant
EVs: 128 HP/252 Atk/128 SDef
Item: Flame Orb/Toxic Orb
Ability: Guts

Or
-Drain Punch
-Ice Punch
-ThunderPunch
-Mach Punch/Fire Punch
Nature: Adamant
EVs: 120 HP/252 Atk/116 SDef/20 Spe
Item: Life Orb
Ability: Sheer Force

Or
-Substitute
-Focus Punch
-Mach Punch
-Payback/Stone Edge
Nature: Adamant
EVs: 252 HP/252 Atk/4 Spe
Item: Leftovers
Ability: Iron Fist

Really, there's no need for Focus Sash on Infernape, since it can take down an opponent before it gets taken down itself. I'd recommend making Infernape go mixed because if Keldeo goes down, who else will deal with physical walls?:
-Overheat/Fire Blast
-Close Combat
-ThunderPunch
-Hidden Power (Ice)/U-turn/Mach Punch
Nature: Hasty/Naive
EVs: 180 Atk/76 SAtk/252 Spe
Item: Life Orb/Expert Belt

Never, ever, ever use physical moves on Keldeo. Ever. No matter how tempting it is to take advantage of Justified, Keldeo is still physically weak, and it already has Secret Sword to deal with Special walls:
-Calm Mind
-Surf/Hydro Pump
-Secret Sword
-Substitute/Hidden Power (Ghost/Ice)
Nature: Timid
EVs: 252 SAtk/4 SDef/252 Spe
Item: Leftovers/Life Orb

Or
-Surf
-Hydro Pump
-Secret Sword
-Hidden Power (Ice)
Nature: Timid
EVs: 252 SAtk/4 SDef/252 Spe
Item: Choice Scarf

Or
-Hydro Pump
-Secret Sword
-Hidden Power (Electric/Ghost)
-Icy Wind/Surf
Nature: Timid
EVs: 252 SAtk/4 SDef/252 Spe
Item: Choice Specs

Or
-Hydro Pump
-Secret Sword
-Icy Wind
-Hidden Power (Bug/Electric)
Nature: Timid
EVs: 252 SAtk/4 SDef/252 Spe
Item: Expert Belt/Life Orb

You're seriously wasting away Lucario's good offensive stats and admittedly decent Speed with your current EV spread and nature. Take a good look at Lucario's stats, and you'll notice that it's geared towards sweeping, rather than defending. Its defensive stats are 70 each, which aren't high, even if it has full investment. However, Lucario's good defensive typing gives it good switch-in opportunities, even with lack of defensive investment. That being said, Lucario shouldn't go mixed; even though its offenses are almost equally high, it'd hard coming up with a mixed set for it, so it's better sticking to one offense only:
-Swords Dance
-Close Combat
-ExtremeSpeed
-Crunch/Bullet Punch/Ice Punch
Nature: Adamant/Jolly
EVs: 4 HP/252 Atk/252 Spe
Item: Life Orb

Or
-Nasty Plot
-Aura Sphere
-Shadow Ball/Dark Pulse
-Vacuum Wave/Hidden Power (Ice)
Nature: Modest/Timid
EVs: 4 HP/252 SAtk/252 Spe
Item: Life Orb
Ability: Inner Focus

Terrakion's STAB moves have good coverage together, and the only Pokemon who resists the combo in OU is Toxicroak, who's already hit very hard by a boosted attack. There are other Pokemon who also resist that combo, but they aren't seen too often in OU at all. Those Pokemon are the Nidos, Golurk, Claydol and Gallade. Really, there's no reason to use Quick Claw on something as fast as Terrakion. Speaking of Quick Claw, it's a luck/hax item, and those items are frowned down upon competitively, due to relying on luck to work. I know you have HP Ice for Gliscor and Dragons, but it's too pathetically weak coming from a Jolly nature to be worth using and those Pokemon are still hit hard by a +2 Stone Edge:
-Close Combat
-Stone Edge
-X-Scissor
-Sacred Sword/Rock Slide/Quick Attack
Nature: Jolly
EVs: 4 HP/252 Atk/252 Spe
Item: Choice Scarf/Choice Band

Or
-Swords Dance
-Rock Polish
-Close Combat
-Stone Edge
Nature: Jolly/Adamant
EVs: 4 HP/252 Atk/252 Spe
Item: Life Orb/Air Balloon

Or
-Stealth Rock
-Taunt/Swords Dance
-Close Combat
-Stone Edge
Nature: Jolly
EVs: 252 Atk/4 SDef/252 Spe
Item: Focus Sash

Or
-Substitute
-Swords Dance
-Close Combat
-Stone Edge
Nature: Jolly
EVs: 252 Atk/4 Def/252 Spe
Item: Salac Berry/Rock Gem/Life Orb

And as a general rule of thumb for EV'ing sweepers: focus on the corresponding offensive stat(s) and Speed (or HP, if the Pokemon is slow as hell). Don't bother going for the defenses at all (Bulk Up users like Conkeldurr are an exception).
