Description
Technical field
The utility model is related to downhole coal mine machinery coalcutter lubricating area, in specially a kind of coalcutter hydraulic-driven from
Dynamic grease lubricating device, the conveying and distribution for being suitable for the drier oil on coalcutter are used.
Background technology
With the development of coal industry, coalcutter is to enlargement, mechanical automation development, due to being limited to by operating environment,
The each oil site of its equipment must obtain good adequately lubrication, just can guarantee that coalcutter is normally transported in severe complex condition
Row.Lubrication is divided into thin oil lubricant and dry oil lubrication.Thin oil lubricant people take much count of, and dry oil lubrication is easy to be ignored by people.Cause
If being not added with for an equipment or adding thin oil less, would not run well, and butter of adding some points less, equipment are run as usual, but lack
The spare and accessory parts of few drier oil, no oil film are formed, in day by day failure, in virtually accelerated wear test, until damage.Because lubricating not in time,
The interruption for entirely exploiting work will be led to by significant trouble occur, lead to huge economic losses.Each coalcutter reprocesses hydraulic pressure
When the overhaul of workshop, the bearing in the driving wheel of outer traction, traveling wheel all pasted by coal slime it is dead, almost without drier oil（Butter）Even
Rust is dead.Therefore how effectively lubrication protection bearing, how to ensure the lubrication of each hinge joint, be that coal mine machinery prolongs
Long-life plays a bottleneck of efficiency；In this case it is necessary to a kind of automatic drier oil adaptable on coal-cutting machinery
Lubricating arrangement ensures the safety and steady normal operation of coal mine machinery equipment.
Invention content
The utility model is in order to solve the problems, such as that dry oil lubrication is not in place not in time on coal-cutting machinery, provides a kind of coal mining
Internal hydraulic drives Automatic grease lubrication device.
The utility model is achieved by the following technical solution：Including hydraulic-driven lubricating grease pump, the hydraulic pressure
Driving lubricating grease pump be fixedly installed in drawing box for coal cutter body side or its outside, the hydraulic-driven lubricating grease pump
The liquid braking device of the hydraulic system of power mouth and coalcutter connects；2 grease outlets of hydraulic-driven lubricating grease pump are respectively with 2
The connection of a grease control piece, the grease control piece by hydraulic tube respectively with the driving wheel of left and right outer traction and traveling wheel
Grease nipple connects.
The utility model is, design not in place for lubrication in the bearing in the driving wheel and traveling wheel drawn outside coalcutter
Unreasonable problem, the portion for having space outside drawing box for coal cutter body inner space sufficiently large advantage or babinet is utilized
Position secures a hydraulic-driven lubricating grease pump, and its power mouth is accessed in hydraulic system, you can normal work；It is adopting
The pressure oil of hydraulic system hydraulic brake circuit in coal machine is low pressure oil, is that high pressure oil passes through pressure reducing valve（Set pressure be 2 ~
3MPa）It is provided after decompression.When not in use, brake interface can be used as the power source of grease pump, grease to the brake of coalcutter
Pump two grease outlets connect respectively with grease control piece, grease control piece be tubular structure, by hydraulic tube respectively with a left side
The right outer driving wheel drawn is connected with the grease nipple of traveling wheel and can be inputted drier oil in the bearing of driving wheel and traveling wheel, is played dry
The effect of oil lubrication.
Preferably, flow is controlled equipped with spiral throttle plug in grease control piece, can be in proportion transported to lubricating grease
Each oil site.
The there is provided scheme of the utility model：Small investment, installation is simple, easy to maintain, highly practical；Also thoroughly solve by
In people inertia cause to safeguard it is not in place and caused by bearing oil starvation damage the problem of, while the utility model is suitable for a variety of adopt
On coal machine, using the maintenance rate for reducing worker the characteristics of itself, the utilization rate of bearing and accessory is improved；It also reduces outer
The accident rate of traction has ensured the operation ratio of coalcutter, while also producing larger economic and social benefits, such as：One is adopted
The outer traction price for repairing of coal machine is about 30,000 yuan, saves 3 × 6=180,000 yuan every year；Every year because outer traction downtime is about 32
Hour it is the time of four classes, 5 knife coals are cut in per tour, about 1800 tons of coals, 260 yuan of coal cost price per ton, value of producing coal less 1800 ×
260 × 4=1872000 yuan.
