Rock drill pressure chain automatic lubrication to improve

Rock drill pressure chain automatic lubrication to improve - 2019 04 - 19 Zhu Yukui YunPeng Sun Deliang ( Inner Mongolia baotou steel union co. , LTD. , embellish mining branch, Inner Mongolia baotou, 014080) 【 Abstract 】 In this paper, through the pressure roller rig ascending chain lubrication status quo analysis, improvement measures are proposed, designed a simple and easy automatic lubrication tools, use homemade chain lubrication tools, not only can solve the problem of chain lubrication need manual operation, also can to control the flow of oil, reduce the waste of oil and grease pollution to other parts of the equipment. Operators can not only improve the work efficiency reduces the labor intensity, but also effectively saves oil use cost. 【 Keywords 】 Rotary drills; Increase pressure chain; Lubrication improvement embellish mining stope of baiyun obo, perforation equipment mainly include KY - B and YZ - 310 55 b type two kinds of rock drill. Two type of open-pit mining with heavy drilling equipment, drill is suitable for large and medium-sized open-pit mine, is our country one of the most advanced rotary drills of independent research and development production, the production scale expands unceasingly along with the company, a lot of big rig introduced step by step, to meet the needs of the company. With the operation of the equipment, the advantages and disadvantages of this type equipment gradually emerge. We according to the characteristics of the use of the equipment in the company for its maintenance method is improved, to ensure efficient operation. 1 rotary drills situation our company choose the rotary drills ( 肯塔基州, 310 b and YZ - 55 b) Belong to high drill stand, using the top rotary closed chain transmission continuous pressure, pressure and walk of the main parts adopt chain transmission. In order to maintain the normal work of the drilling rig, prolong the service life of the chain, must be in accordance with the provisions of the various parts of the cycle of chain lubrication. But the original car chain lubrication system belongs to the dry oil injection lubrication, spewing oil lubrication system pillars, and unable to control stress effectively, and lubricating oil consumption is larger, and poor liquidity dry oil the chain lubrication effect is not ideal. So we use of chain lubrication has been rare artificial lubricating oil can, but my company imported drill belongs to drill stand high, increase pressure single closed chain section 946, a total length of about 50 meters, a total of 2 root. Equipment is running, the chain to move slowly, artificial lubrication single chain need 40 minutes, due to the baiyun obo located in highland, climate conditions, sand all the year round, winter temperature is very low, and people need long time standing on the main drive gearbox, close to the chain, operation conditions and physical exertion large, high risk, the redundant grease will damage to the equipment on other institutions. Therefore very need to design a convenient tool to replace manual lubrication status quo. 2 chain lubrication to improve the concrete measures of making tool is simple and practical, make material also can be used for waste. With Angle steel and iron welding size appropriate lubricating oil tank, for the convenience of ups and downs when drill rack installation and dismantling, lubricating oil box adopts active suspension, the tank bottom drill a 20 mm diameter hole, and then welding section of the same diameter iron pipe in order to join lubricating oil pipe, iron pipe connected to the oil pipe joint ball valve, used to adjust the volume of oil. Oil pipe end tubing head alignment within the chain plate, and the chain to keep a distance of 10-15 mm fixed, can better make lubricating oil penetrated into the interior of the shaft and shaft sleeve and roller, and can reduce the wind and vehicle vibration influence on oil droplets direction, thus reduce the drops of oil pollution to the body and the waste lubricating oil. Lubrication in ball valve don't drive too big, can make lubricating oil drip, so also can have the effect of cleaning, saving ( As shown in figure 1) 。 Figure 13 application effect by using the above chain lubrication tools, not only can solve the problem of chain lubrication need manual operation, also can to control the flow of oil, reduce the waste of oil and grease pollution to other parts of the equipment. Can not only improve the work efficiency reduces the labor intensity, but also effectively saves oil use cost. The boost pressure chain lubrication tools are currently KY - automatically 13 # and YZ - 310 b 55 b used on 10 # drill, use effect is good. The next step will continue to focus on the lubrication tools and will be used widely in other drill. References: 1] 肯塔基州, 310 b with the: 'peration &maintenance manual of rotary drills.
