Plate and locking key, to prevent it from being rotated with platform.Bottom is carried out axially solid in undercarriage bea with spheric washer, pivot nut
It is fixed.Top is sequentially installed with rotary lubrication fat joint, rotary pneumatic joint, low-tension collecting ring, high-voltage collecting ring and safety guard.In
Centre pivot be hollow shaft structure, towards the compressed air line of part, lubricant grease pipeline and car under power shovel car under motor,
The cable and control line of magnetic valve pass through in heart hole therefrom.Former feeder includes revolving dial 1, chassis 2, spheric washer
3rd, pivot nut 4, oil circuit joint 5, gas path joint 6, safety guard 7, rotary lubrication fat joint 8, Primordial Qi joint 9, low pressure current collection
Ring 10 and high-voltage collecting ring 11（See Fig. 1）.Primordial Qi joint includes flange 26, gland 27, seal box 28, stay-bolt 29, bushing
30th, V-seal component 31, air flue 32 and screw 33（See Fig. 2）.
Walking rotary pneumatic joint, which is played, delivers to the compressed air of air compressor machine in Platform Machinery room under car, opens walking electronic
The effect of machine band-type brake and shift fork clutch.
The motive power of power shovel running gear provides power by walking motor, and the braking ratchet wheel of motor is air-pressure brake,
Belong to normally closed type, stuffiness, band-type brake is not opened, it is impossible to worked.
Walking rotary pneumatic joint pipeline is, through centerpivot center cavity, to pass to walking each several part；Therefore, want to change
The seal of gas joint, it is necessary to after other parts mounted thereto are all removed, could be repaired.First, remove
Safety guard；Then high-voltage collecting ring is removed（Because high-voltage collecting ring is connected with 6000V high-tension electricity, before dismounting, it is necessary to will be whole
The high-tension electricity of platform power shovel is broken；It is another to introduce power supply from external transformer, so that maintenance and renovation is used, predominantly illumination, electric drill, mill
Ray machine is used）；Afterwards, then by low-tension collecting ring and each cable, small wire terminal remove；Then, universal gas joint could be carried out
Dismounting；Finally, cable, line and the airduct each ring connected is all extracted out out of centerpivot cavity, in order to recover peace
Operation during dress；Gas joint is disassembled, V-seal component is changed；Then recovery assembling, test run are progressively carried out.Whole maintenance process
Very very complicated, labor intensity is very big, and expends that man-hour is long, and the influence to production is very big.
The content of the invention
The problem of the purpose of this utility model exists aiming at prior art and defect are supplied there is provided a kind of rotation of power shovel
Device, labor intensity when reduction maintenance is changed, shortens maintenance man-hours, improves overhaul efficiency.
What the purpose of this utility model was realized in：A kind of power shovel rotates feeder, including revolving dial, chassis,
Spheric washer, pivot nut, oil circuit joint, gas path joint, safety guard, rotary lubrication fat joint, Primordial Qi joint, low pressure current collection
Ring, high-voltage collecting ring and new gas joint, it is characterised in that：New feeder new gas joint more than former feeder, in original
Car goes out internal thread in the top gland hole of feeder topmost high-voltage collecting ring, prepares a gas joint base, new gas is connect
Head placement thereon, load onto high pressure rubber airduct pass to it is standby under car；For the sake of assurance, in high and low pressure collector ring
The link rod that insulation degree is 10KV is put on a part of airduct.
It is characterized in that：The new gas joint, including new gas joint housing, hollow shaft, lock nut, dust ring, axle
Pressure cap, bearing, plug, sealing ring, spring, sealing ring baffle ring, holding screw, sealing ring gland and bolt；New gas connects
Head is compared with original gas joint, small size, and the new gas joint of flow, pressure identical from pipe joint by being installed on high pressure current collection
On the end cap of ring, separately a point branch road gas circuit is in parallel among air-channel system, effectively improving the reliability of system；New gas joint
Due to needing to be arranged at the top of former feeder, therefore need with small volume, lightweight, stream pressure when meeting work and
The demand of flow.
It is characterized in that：New gas circuit gas joint newer than Primordial Qi Lu Duoyi and stop valve；Primordial Qi joint still retains and made simultaneously
With, only it is repaired in medium-capital overhauling.
Compared with prior art, the utility model has the advantages that：Rational in infrastructure, scientific allocation, using reliable is greatly reduced
Labor intensity when maintenance is changed, shortens maintenance man-hours, improves overhaul efficiency.
