Abstract
The utility model discloses an automatic oil injection system for an air hammer, and relates to the technical field of related equipment for automatically injecting oil for the air hammer. The automatic oil injection system for the air hammer comprises an automatic oil injection device, a high pressure hose, a check valve and a tee, wherein the tee is arranged on a gas injection pipeline and is connected with the high pressure hose through the check valve, and the high pressure hose is connected to the automatic oil injection device. The automatic oil injection system for the air hammer solves the problems that when a single stand column is connected into the prior air drilling and lubricating oil is injected, the time interval is long and the lubricating efficiency is low, prolongs the service life of the air hammer and improves the impaction efficiency.
Description
Technical field
The utility model relates to the relevant device technical field to the pneumatic hammer automatic oiling.
Background technique
In recent years, the just unique advantage fast development with it of domestic air drilling technology, pneumatic hammer, as the main tool of air drilling deviation prevention and fast, has used 260 wells so far from 2005, and the accumulative total drilling depth surpasses 28 myriametres.Service condition for many years shows, reasonably construction parameter and good lubricated be the determinant factor that determines pneumatic hammer working life and efficiency of breaking rock, and the air hammer lubricating generally adopted at present oil dosing method is all during make up a joint (column), the disposable lubricant oil that adds the 500-1000ml left and right from the drilling rod hydrophthalmia, there is following problem at present in this kind of oil filling mode: one, at drilling tool more in short-term, the lubricant oil injected is along with the gas high-speed circulating, be circulated to ground in short time from drilling tool water hole at the utmost point, when pneumatic hammer is most in non lubricant oil lubricated state, two, formation lithology changes change in the time of may causing boring, thus the time lag of oil filling inhomogeneous (take and make up a joint as example, may change at 20-60min).Above problem has limited the working life of pneumatic hammer, and then the time that has increased its user cost and made a trip and change, therefore, be badly in need of a kind of can both be continuously during whole gas creeps into to the device of charging-up lubricant oil in drilling tool, guarantee constantly can obtain enough lubricant oil during pneumatic hammer creeps into.
Through retrieval, also find no to the Patents of pneumatic hammer oiling or the report of periodical file at present.
The model utility content
The purpose of this utility model is to solve the lubrication problem while using pneumatic hammer to carry out the air drilling operation, provide a kind of during air drilling, inject continuously the system of oil lubrication pneumatic hammer in drilling tool, solved in the past air drilling injects lubricant oil and causes the problem that the time lag is long, lubricating efficiency is low when making up a joint (column), thereby extended the working life of pneumatic hammer, increased target efficiency.
The utility model is by adopting following technical proposals to realize:
A kind of pneumatic hammer auto Oil-filling System Using is characterized in that: comprise automatic oiling device, high pressure hose, and one-way valve and threeway, described threeway is arranged on gas injection pipeline, and threeway is connected with high pressure hose by one-way valve, and high pressure hose accesses on automatic oiling device.
Described automatic oiling device comprises electric oil-filling pump, PLC controller, contactor and Lubricating oil tank, and electric oil-filling pump is arranged in Lubricating oil tank, and contactor is connected with electric oil-filling pump with the PLC controller respectively.
Described threeway is connected with one-way valve by diameter changing nipple.
Compared with prior art, the beneficial effects of the utility model show:
1, in the utility model, by a threeway is set on gas injection pipeline, then lead to the mode of injecting lubricant oil in gas injection pipeline by high pressure hose and three by automatic oiling device, can in drilling tool, inject continuously the system of oil lubrication pneumatic hammer, solved in the past air drilling injects lubricant oil and causes the time lag long when making up a joint (column), the problem that lubricating efficiency is low, thereby extended the working life of pneumatic hammer, increased target efficiency, further improve pure brill timeliness, reduce and make a trip the replacing time, and the utility model is simple in structure, reliable and stable, can be provided in all air drilling maintenance crews, installation at short notice while needing to use pneumatic hammer.
2, in the utility model, by high pressure hose, one-way valve, with gas injection pipeline, be connected, its integral pressure rank is consistent with gas supply line pressure rank, can guarantee the Security of this device duration of work.
3, in the utility model, adopt the structural type of specific automatic oiling device, can pass through PLC controller control contactor, thereby control the unlatching of electric oil-filling pump or close, thereby can arbitrarily adjust time, the injection amount of injecting lubricant oil.
The accompanying drawing explanation
Below in conjunction with specification drawings and specific embodiments, the utility model is described in further detail, wherein:
Fig. 1 is structural representation of the present utility model
Mark in figure:
1, gas injection pipeline, 2, threeway, 3, diameter changing nipple, 4, one-way valve, 5, high pressure hose, 6, automatic oiling device, 7, contactor, 8, the PLC controller, 9, electric oil-filling pump, 10, Lubricating oil tank.
Embodiment
With reference to Figure of description, preferred forms of the present utility model is:
During air drilling, a reserved threeway 2 on main gas supply line, be connected with one-way valve 4 by diameter changing nipple 3, and then will be connected with automatic oiling device 6 with high pressure hose 5.Automatic oiling device 6 mainly is comprised of following main body: electric oil-filling pump 9, PLC, contactor 7, Lubricating oil tank 10, between operational period, control oiling device single operating time and the time lag (if the major diameter hammer body of use Φ 330mm and so on by PCL, oiling device is in the continuous firing state), and action command is sent to contactor 7; Contactor 7, after receiving the PCL instruction, controls the unlatching of electric oil-filling pump 9 or cuts out; Electric oil-filling pump 9 after starting the discharge capacity with 15～80ml/min inject lubricant oil to main gas supply line, then by standpipe, drilling tool by air circulation to pneumatic hammer.
Certainly, except the automatic oiling device 6 of this specified structure, existing automatic oiling device 6 also can be realized, but effect is not as this specific automatic oiling device 6.
The utility model pneumatic hammer automatic oiling device 6, be connected with gas supply line by high pressure hose 5, one-way valve 4, and its integral pressure rank is consistent with gas supply line pressure rank, can guarantee the Security of this device duration of work.
