Because the large arm of crane is long, its surface area ratio is larger, need to often stretch the flat wiping oil lubrication of lying prone of large arm, nonetheless lubricating oil smears not aspect very, especially winter, bad operation especially after the butter of sometimes smearing solidifies, need to quit work during coating lubricating oil on the other hand, affects work efficiency.On the whole, the large arm of existing crane is wasted time and energy when coating lubricating oil, but also waste lubricating oil.
Utility model content
The technical matters that the utility model solves is to provide a kind of crane large arm lubricating system, can when crane is worked, automatically complete lubricatedly, simplifies the smearing of lubricating oil of the large arm of crane, and can save lubricating oil.
The utility model is to be achieved through the following technical solutions:
The large arm lubricating system of crane, comprises the oil pump being connected with fuel tank, is provided with piston in oil pump, and the oil pipe that is provided with a plurality of nozzles is connected with oil pump; Top board is connected with oil pump by elastic element, and top board is also connected with the piston of oil pump by push rod slidably.
Described push rod is arranged in top stem casing, and top stem casing is fixed on oil pump.
Described top stem casing is fixed on oil pump bottom, and push rod is fixedly connected with piston.
Described oil pipe is connected with oil pump by switch.
Described oil pipe is provided with a plurality of nozzles, and nozzle is arranged on the top of the large arm of crane.
Described top board is connected with oil pump by spring.
On described fuel tank, be also provided with fuel lid, lubricating oil is housed in fuel tank.
When top board is encountered in the large arm withdrawal of crane, give roof pressure, the elastic element between top board and oil pump is compressed, and top board is displacement backward, and drives piston displacement backward by push rod, and oil pump sucks lubricating oil from mailbox; When the large arm of crane stretches out, roof pressure is removed, and elastic element is replied and driven top board displacement forward, and top board drives piston forward to advance by push rod, and the lubricating oil in oil pump is pushed in oil pipe, from nozzle, is sprayed onto the lubricated face of the large arm of crane.
The large arm lubricating system of described crane is arranged between the joint and joint of the large arm of crane.
Compared with prior art, the utlity model has following useful technique effect:
The large arm lubricating system of crane that the utility model provides, by being arranged between the joint and joint of the large arm of crane, the pressure that has utilized cleverly the large arm of crane himself to produce when flexible, when the large arm of crane has been regained, by the contact of top board and the conversion of elastomeric element, coordinate oil pump piston when flexible, to suck lubricating oil, when extending, from nozzle, be sprayed onto the lubricated face of large arm, like this in the elongation along with the large arm of crane, its large arm total length can be dripped lubricating oil, while having realized the large arm work of crane, just can automatically complete smearing of lubricating oil.
The large arm lubricating system of crane that the utility model provides, flexible as required, such as adjusting the parameter of elastic element, oil pipe, nozzle, can adapt to the lubricated of the dissimilar large arm of crane, and oil pipe is controlled by switch, when lubricated, control fuel charge size, lubricated can close swap switch when enough.
The large arm lubricating system of crane that the utility model provides, has not only facilitated the lubricated of the large arm of crane, and can save lubricating oil, carrying out when the large arm of crane is lubricated stretching out specially large arm coating butter, use used oil, gear lubricant as lubricating oil, reduce expenses, turn waste into wealth.
