Description
Technical field
The invention belongs to power shovel frame for movement technical field, more particularly to a kind of electric dipper slewing gear fixing structure.
Background technology
Swiveling gear is one of most important part in power shovel, its by with revolution rolling disk bull gear engage realize platform and
Relative rotation between base, meet revolution action during power shovel operation.Original 12m3Electric dipper slewing gear passes through with rotary vertical shaft
Spline connects, and housing pin is screwed into the screwed hole of centre of rotary vertical shaft end, to realize the axial restraint of swiveling gear.Two
Group check bolt is screwed into the locking screw thread hole of rotary vertical shaft end through two circular holes on housing pin, is reached to compressing spiral shell
The locking effect of silk.
But said structure has certain technical problem, i.e., after housing pin is tightened in place, circular hole thereon is with returning
The locking screw thread hole for turning vertical shaft cannot be guaranteed completely with one heart, to cause housing pin not assemble.The anti-Pinus of fixation of swiveling gear
In critical process, if mine scene swiveling gear loosens, the operation action of power shovel can be had a strong impact on, it is necessary to SDR, and
The critical component aggravation fatigue wears such as rotary reducer, turning motor, revolution rolling disk can be caused or even damaged, this loss is ore deposit
Mountain enterprise is unacceptable.
The content of the invention
Present invention seek to address that the swiveling gear assembly precision of power shovel is difficult to ensure that swiveling gear is easily loose in the prior art
The technical problem such as dynamic and Assembly stability can be improved by providing one kind, the electric dipper slewing gear fixed knot for avoiding swiveling gear from loosening
Structure.
The present invention is adopted the technical scheme that to solve technical problem present in known technology：A kind of electric dipper slewing tooth
Quick release structure, including rotary vertical shaft, housing pin, check bolt and swiveling gear, the swiveling gear are arranged on described return
Turn on vertical shaft, the end of the rotary vertical shaft has screwed hole of centre, and the housing pin is installed by the screwed hole of centre
Axial restraint is carried out on the rotary vertical shaft and to the swiveling gear, it is characterised in that：Also include adjust pad；The tune
Whole pad is located between the housing pin and the end face of the rotary vertical shaft；With the center on the end face of the rotary vertical shaft
The center of screwed hole is that the center of circle is evenly equipped with 4 locking screw thread holes；The housing pin is provided with 4 and the locking screw thread hole pair
The arc waist hole answered；The end of the rotary vertical shaft is provided with the institute coordinated through the arc waist hole and the locking screw thread hole
State check bolt.
The present invention has the advantages and positive effects of：
The present invention can substantially reduce the assembly difficulty of housing pin and rotary vertical shaft, can be achieved once to assemble successfully.With
Original structure is compared, and is once assembled successful probability and is lifted 2 times, swiveling gear can be fixed accurately and reliably.So not only
The requirement for producing, assembling can be met, workload is reduced, reduce cost.The fault rate of equipment can also be effectively reduced, greatly
Meet that bargh works continuously the requirement of stability to power shovel.

Embodiment
In order to further understand the content, features and effects of the present invention, hereby enumerating following examples, and coordinate accompanying drawing
Describe in detail as follows：
Refer to Fig. 1-Fig. 6, a kind of electric dipper slewing gear fixing structure, including rotary vertical shaft 1, housing pin 2, locking spiral shell
Bolt 3 and swiveling gear 4.The swiveling gear 4 is arranged on the rotary vertical shaft 1.In the present embodiment, the swiveling gear 4 with
The rotary vertical shaft 1 is connected by spline.The end of the rotary vertical shaft 1 has screwed hole of centre 1-1, the housing pin 2
It is arranged on by the screwed hole of centre 1-1 on the rotary vertical shaft 1 and axial restraint is carried out to the swiveling gear 4.
Also include adjust pad.The adjust pad located at the end face of the housing pin 2 and the rotary vertical shaft 1 it
Between.
On the end face of the rotary vertical shaft 14 locking screw threads are evenly equipped with by the center of circle of the center of the screwed hole of centre 1-1
Hole 1-2 (M20 × 4.The housing pin 2 is provided with 4 arc waist hole 2-1s corresponding with the locking screw thread hole 1-2.It is described
The end of rotary vertical shaft 1 is provided with the check bolt coordinated through the arc waist hole 2-1 and locking screw thread hole 1-2
3.The locking screw thread of the end of rotary vertical shaft 1 is screwed into after tightening with the arc waist hole 2-1 of four check bolts 3 through housing pin 2
In the 1-1 of hole, reach anti-loose effect.Because the end face of housing pin 2 is designed to four arc waist hole 2-1, it is significantly greatly increased vertical with revolution
The end lock screwed hole 1-2 of axle 1 concentric probability, it can be achieved once to assemble successfully.Once assembled successfully compared with original structure
Probability lifted 2 times.If once assemble it is unsuccessful, can by increase and decrease adjusting shims quantity small range change housing pin
The amount of screwing.
In order to which check bolt is further locking, check bolt includes tightening latch and head, and the head is provided with locking through hole,
It is furnished with locking jackscrew in locking screw, locking through hole is parallel with check bolt with the axis of locking jackscrew, and the axle of locking jackscrew
Line is more than the diameter of tightening latch to distance between the axis of check bolt.
