Detailed Description

The invention is further described below with reference to specific preferred embodiments, without thereby limiting the scope of protection of the invention.

For convenience of description, the relative positional relationship of the components, such as: the descriptions of the upper, lower, left, right, etc. are described with reference to the layout directions of the drawings in the specification, and do not limit the structure of the present patent.

Example 1:

as shown in fig. 2 to 4, the tank body 13 of an embodiment of the automatic oil feeding and discharging device of the present invention is designed in a capsule shape, so that it has a stronger pressure resistance than a rectangular or cylindrical tank body. The bottom of the oil tank body 13 is provided with a second oil port, the second oil port is connected with a lower transparent rubber tube 12 through an anchor ear 8 by a bent joint 1301, the other end of the lower transparent rubber tube 12 is connected with one end of a switch valve 11 by a joint, the other end of the switch valve 11 is connected with one end of an upper transparent rubber tube 9 by a joint 10, and the other end of the upper transparent rubber tube 9 is tightly connected with the corrugated end of a T-shaped joint 7 by the anchor ear 8. The locking nut 6 is sleeved and buckled at the other end of the T-shaped joint 7, so that the upper transparent rubber tube 9 cannot be twisted along with rotation in the screwing process of the locking nut 6. The internal thread of the lock nut 6 is screwed with the external thread at the big end of the transition joint 3. An O-shaped ring 5 is arranged between the T-shaped joint 7 and the transition joint 3 to prevent oil leakage. The small thread end of the transition joint 3 is connected with an oil drain hole of the gearbox 103, and a sealing ring 4 is arranged between the gearbox 103 and the transition joint 3 to prevent oil leakage. The upper portion of the oil tank body 13 is provided with a first oil port 1302, the first oil port 1302 is provided with an oil tank cover 15, the oil tank cover 15 is provided with a through hole, one end of the through hole is communicated with the first oil port 1302, the other end of the through hole is connected with one end of a PU hose 16 through a small hoop, and the other end of the PU hose 16 is connected with a PH connector 18. A sealing ring 14 is arranged between the oil tank cover 15 and the oil tank body 13 to prevent air leakage in the oil filling process.

The tail part of the dust blowing air gun 20 is connected with the common compressed air in a workshop through an air pipe, and an air blowing nozzle is connected with an SM self-locking quick connector 19. The SM self-locking quick connector 19 and the PH connector 18 can be quickly inserted, and the dust blowing air gun 20 can conveniently and freely control the air quantity of compressed air and the on-off of the compressed air.

The utility model discloses during the use, rig 1 hoists back on the test run test platform 2, and the oil drain hole of gearbox 103 bottom is screwed up to the tip screw thread of transition joint 3, sets up sealing washer 4 and prevents the oil leak. The locking nut 6 is screwed down to enable the T-shaped joint 7 to tightly press the O-shaped ring 5, oil leakage is prevented, the switch valve 11 is opened, the dust blowing air gun 20 is communicated with workshop public compressed air, the PH joint 18 is inserted into the SM self-locking quick joint 19, and at the moment, the dust blowing air gun 20 cuts off the compressed air to flow to the oil tank body 13. Pulling the trigger of the dust blowing air gun 20 by using the forefinger, compressed air flows to the oil tank body 13 through the dust blowing air gun 20, under the pressure of 0.8MPa of the compressed air, gear oil in the oil tank body 13 flows to the gearbox 103 through the lower transparent rubber tube 12, the switch valve 11 and the upper transparent rubber tube 9, because the inner cavity of the gearbox 103 is communicated with the inner cavity of the supporting seat 102, air in the inner cavity of the gearbox 103 is discharged through the air holes of the ventilating bolt 101 through the inner cavity of the supporting seat 102, so that an oil source in the oil tank body 13 continuously flows into the gearbox 103, the oiling speed is controlled through the opening and closing degree of the trigger of the dust blowing air gun 20, and the oiling amount is determined through the oil viewing window in the oiling process. After the refueling is completed, the on-off valve 11 is closed to prevent the oil inside the transmission case 103 from flowing back to the oil tank body 13. Like this, one person only needs the time of one minute or so just can easily accomplish refueling of rig gearbox, and the oil leak is few. The PH joint 18 buckled in the SM self-locking quick joint 19 is pulled off, and the dust blowing air gun 20 is held to start the oiling work of another machine table. In the process of oiling other drilling machines, the drilling machine which is already oiled can carry out trial run inspection work, and time is saved.

After the test run is finished, the switch valve 11 is opened, the gear oil in the gearbox 103 automatically flows back to the oil tank body 13, the switch valve 11 is closed after the oil is completely drained through the upper transparent rubber tube 9, the lock nut 6 is unscrewed, the transition joint 3 is unscrewed from the bottom of the gearbox body 103, and the oil drainage is finished. When the oil is drained, the operator can carry out other work, the waiting time for oil drainage is avoided, and the labor efficiency is improved.

The above description is only for the preferred embodiment of the present application and should not be taken as limiting the present application in any way, and although the present application has been disclosed in the preferred embodiment, it is not intended to limit the present application, and those skilled in the art should understand that they can make various changes and modifications within the technical scope of the present application without departing from the scope of the present application, and therefore all the changes and modifications can be made within the technical scope of the present application.
