080 and 085 is swivel bearing oiling pipe joint, is connected on swivel bearing, and 090 is grease nipple；When filling butter, butter passes through
Grease nipple-butter pipe-enter swivel bearing, lubricating rotary bearing.
The defects of connected mode in upper figure is present is as follows：
1st, oil connection and oil pipe are connected using nut compressing, and reliability is low, easily comes off.
2nd, oil fuel tube pipe shaft is nylon material, and pressure voltage is low, low intensity, easily snaps off.
3rd, because oil pipe and swivel bearing coupling part are all in driver's cabin bottom, when oil fuel tube and pipe joint comes off or oiling
After pipe fractures, it is not easy to find, when causing to fill butter, butter can not reach swivel bearing, and swivel bearing cannot because of long-time
Lubrication causes inordinate wear.
4th, after rotation causes abrasion, Replacement and Repair quantities it is very big, it is necessary to whole swivel bearing is supported engine,
Most of dismounting of the excavator such as support and its large arm, maintenance cost are high.
5th, repair time is grown, and spare part could be repaired for more than 3 days after preparing in place, larger to Influence of production.
6th, swivel bearing is worth higher, 3.1 ten thousand yuan of a swivel bearing.
The content of the invention
The technical problems to be solved in the utility model is：A kind of excavator swivel bearing oiling pipe connecting structure is provided, connect
Head is high with oil pipe connection reliability, difficult for drop-off, and oil fuel tube pressure voltage is high, and intensity is high, is not easily broken, and maintenance cost is low, maintenance
It is convenient.
The technical solution of the utility model is as follows：
A kind of excavator swivel bearing oiling pipe connecting structure, including backplate positioned at excavator forward right side and positioned at digging
Valve block on the inside of pick machine backplate, valve block outside are grease nipple, are connected on the inside of valve block with oil fuel tube；Here on the inside of excavator backplate
Refer to the one side that backplate does not contact with working environment.One end face of valve block is connected with backplate inner surface, perpendicular to foregoing end
Two relative surfaces in face are respectively the inner surface and outer surface of valve block, and inner side here refers to relative in excavator
The side of portion's structure, outside refer to the side relative to working environment.
The pipe shaft of the oil fuel tube is high-pressure oil pipe, and its both ends connects straight peen and elbow respectively, and straight peen is connected with valve block, curved
Head is connected through becoming head with swivel bearing oiling seat；
The change head includes six prism sections, and six prism section both ends are respectively the cylindrical section of external diameter not grade, two cylinder segment tables
There is screw thread in face.
The valve block welding is on the inside of excavator backplate.
The pipe shaft external diameter of the oil fuel tube cylindrical section external diameter larger with becoming head top external diameter is equal.
The elbow of the oil fuel tube is in 90 degree of bendings.
Two cylindrical section external diameters for becoming head are respectively Φ 10 and Φ 14.
Round platform changeover portion is provided between the six prisms section and the less cylindrical section of external diameter.
Compared to current swivel bearing oiling pipe connecting structure, the utility model possesses following advantage：
1. using the high-pressure oil pipe of compacting as oil fuel tube pipe shaft, intensity is high, and pressure voltage is high, is not easily broken.
2. high intensity, which becomes head, screws in swivel bearing oiling seat, hydraulic oil tube bend ends are connected with becoming head, straight peen end and butter
Mouth valve block connects, solid and reliable.
3. the block welding of grease nipple valve, on the inside of excavator backplate, protection is preferable, is hardly damaged.
4. grease nipple is outside, it is easy to fill lubricant grease, ensures swivel bearing lubrication, extend swivel bearing service life.
