Abstract
The utility model discloses an oil changing gun used for a crawler type running mechanism, which provides the oil changing gun with two oil paths for the crawler type running mechanism. The utility model is mainly composed of a gun body and an oil return nozzle with two oil paths, an oil outlet valve and an oil inlet valve connected with the gun body. The wrenching rod of the gun body is connected with the valve cores of the oil inlet valve and the oil outlet valve. The oil inlet valve is provided with an oil return path communicated with the oil outlet valve. The oil return path of an oil feeding nozzle is communicated with the oil return path of the oil inlet valve. The two valve cores are opened by wrenching the level. Pressure oil is pressed from one end of the lubricating cavity of the rolling wheels of the running crawler type mechanism by the oil feeding nozzle through the oil inlet valve. Meanwhile, the old oil is extruded out from the other end and then is discharged out from the oil outlet valve by the oil return path of the oil feeding nozzle to complete the oil replacement.
Description
The utility model relates to a kind of oiling machinery.
In the rotary part roller of guide wheel, track roller and this class creeper undercarriage of holder sprocket wheel, all be marked with lubricant oil, increase the service life to keep its good working order.For preventing the leakage of lubricant oil in intrusion of silt or dirt and the machine, fluctuate hermetical ring is housed all generally.In long-term work, metallic dust and sealing bits that the oil meeting be sneaked into wherein pollute, and fluctuate hermetical ring may be damaged and cause little by little seepage minimizing of oil mass; Whether therefore, need make regular check on oil sealing and leak, the oil mass of lubricant oil and oily situation carry out repairing or change adding fresh oil.Traditional mode of changing oil is the angle that the car body inclination is certain, and the nozzle with a kind of single oil duct pours into fresh oil to utilize potential energy to make old oily spontaneous current in the car release behind the car body again.The way shortcoming that this dependence is discharged naturally is time-consuming many and drain endless, can only discharge about 40% of total oil mass usually, and changing oil can not be thorough, needs all generally to carry out that secondary is drained the oil and repairing.
The purpose of this utility model is the above-mentioned shortcoming that overcomes the existing mode of changing oil, and for creeper undercarriage provides a kind of rifle of changing oil, whether this rifle of changing oil can be replaced out with old oil in the perfusion fresh oil, can also realize detecting fluctuate hermetical ring and leak.
The purpose of this utility model is to realize by this technological scheme of nozzle that designs two oil ducts.Its formation comprises pikestaff, rifle body and tommy bar, also being provided with one in the front portion of rifle body has into, the outlet valve of oil outlet, one has into, the oiling valve of oil outlet and one is provided with two oil duct zerks of back oil road, wherein, oiling valve is made of oil-feed valve body that is provided with back oil road and the oil-feed spool that has recoil press spring, outlet valve is made of fuel-displaced valve body and the fuel-displaced spool that has recoil press spring, fuel-displaced valve body is connected rifle body front portion, the oil-feed valve body is connected on the fuel-displaced valve body with fuel-displaced valve body is coaxial, its back oil road communicates with the filler opening of outlet valve, zerk is connected on the oil-feed valve body, its back oil road communicates with the back oil road of oil-feed valve body, described fuel-displaced spool is a tubular spool that is sleeved on the oil-feed spool, the control end of two spools is stretched in the rifle body, and plate stem passes the spool control end and is hinged on the rifle body.During work pressure oil-source is connected to the filler opening of oiling valve, zerk puts in the oil hole of roller and makes the oil outlet of zerk and an end of the lubricating cavity of roller joins, the other end of back oil road and roller lubricating cavity joins, pulling tommy bar makes two spools be in the unlatching shape together, pressure oil then is pressed in the roller lubricating cavity through zerk old oil is entered the outlet valve discharge through the back oil road of zerk, the back oil road of oiling valve, finishes replacement new, old oil.
The control end face and the tommy bar of oil-feed spool are kept often connecing, the control end face of fuel-displaced spool and the control end face of oiling valve are provided with in the same way and are positioned on the motion path of tommy bar, when pulling tommy bar to a certain position, oiling valve is opened and outlet valve keeps cutting out, this moment can only oil-feed can not be fuel-displaced, whether the pressure gauge on the oil circuit both can detect fluctuate hermetical ring the generation of leakage: fill with the back at oil and continue oil-feed, close after making oil pressure be increased to certain value, if the pressure tabular value descends, illustrate that then seal ring damages, have to leak to exist.
Pressure gauge can be set directly on the oil-feed valve body of the rifle of changing oil, constitute one not only can change oil, but also the multi-functional rifle of changing oil that can hunt leak.
Advantage of the present utility model:
1, change oil easyly rapidly, the vehicle original position is parked and is got final product, and has both filled it up with fresh oil when old oil is extruded, needn't the secondary repairing, and efficient improves greatly.
But 2 emptying sump oils clean thoroughly;
3, can detect the Sealing of inefficacy, prevent that oil leakage phenomenon from taking place, and guarantees effectively lubricating.
Below in conjunction with drawings and Examples the utility model is described further.
