Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and be not intended to limit the protection scope of the present invention and limit the scope of the invention.
As shown in Figure 1, Figure 2 and Figure 7, planet carrier 13 of the invention is separate structure by traditional structure design, by restocking
Body 133, lower frame 134 and multiple connecting shafts 135 of connection upper frame 133 and lower frame 134 are formed;Upper frame 133 and lower frame
134 centers have a centre bore, which is used to accommodate sun wheel shaft 26;The space 137 formed between adjacent connecting shaft 135
Planetary gear is installed available for accommodating.This structure not only alleviates the weight of planet carrier, and avoids and opened up on planet carrier
For accommodating the mounting hole of planetary gear, difficulty of processing and production cost are reduced, makes the mounting hole 136 of fixed planetary gear axis pin more
Add and facilitate processing, ensure that the control of the fit tolerance of mounting hole, gap and assembly precision.
Connecting pin 132 on one, lower connecting pin are respectively provided on the upper surface of upper frame 133, the lower face of lower frame 134
131.Upper connecting pin 132, lower connecting pin 131 can be integrally formed with upper surface, the lower face of lower frame 134 of upper frame 133
Or component is independent, it connect, be assembled into one with the upper surface of upper frame 133, the lower face of lower frame 134.
The planet carrier 13 of the present invention is arranged in the torsion increasing device 5 of churning driven power head, alleviates the dead weight of torsion increasing device,
After the output torque of power head is made to pass through torsion increasing device, final output torque has obtained maximum promotion so that churning driven
The power head of machine can meet larger diameter and the casing of bigger depth is buried.
With reference to shown in Fig. 3-Fig. 8, churning driven includes rotary digging host 1, mast 2, drilling rod 3 and is supported and fixed on mast
Power head 4 and torsion increasing device 5, power head 4 and torsion increasing device 5 can move up and down along mast 2, power head 4 drive drilling rod 3 carry out
Drilling, while 4 output terminal of power head is connected by axis pin 6 with torsion increasing device 5, and power head 4 is by torsion increasing device 5 by final torque
Increase, the casing that major diameter can be met or more deeply spend by making 5 output terminal of torsion increasing device are buried.
Torsion increasing device 5 include torque case 7, bracket 9 and the axis pin 8 of the fixed torque case 7 of connection and bracket 9, bolt 10 and
Snap-gauge 11, torque case 7 are connect with bracket 9 by axis pin 8, and 6 axis direction of axis pin is parallel with 4 centre of gyration of power head.Bracket 9
One end is connect with torque case 7, and the other end stretches out two claws and is stuck on mast 2, makes bracket 9 can be along 2 vertical sliding motion of mast.Torque
Case 7 is attached to by bracket 9 on mast 2, can increase its stability and reliability, reduces its dead weight to the greatest extent and power head 4 is made
Into influence.But since the distance between mast 2 and drilling rod 3 are limited, the structure design inside torque case 7 should meet
Assembling, construction and the production cost demand of the confined space, meet the needs of torque output, intensity, rigidity and fit precision again,
And its dead weight is reduced as far as possible, therefore, the structure design inside torque case 7 needs to consider various aspects factor, finally
Design can meet demand torque case.
In torque case 7,4 output torque of power head is transferred to sun wheel shaft 26, sun wheel shaft 26, planetary gear by axis pin 6
27 constitute a kind of planetary gear speed reducing mechanism with gear ring 14, and sun wheel shaft 26 is hollow shaft, and formation can accommodate what drilling rod 3 passed perpendicularly through
Space makes torque case 7 that can move up and down with power head 4 along mast 2, does not influence the movement of drilling rod 3.26 upper end of sun wheel shaft
It is connect by axis pin 6 with 4 output terminal of power head.Sun wheel shaft 26 is the input terminal of planetary gear speed reducing mechanism, and gear ring 14 subtracts for planet
The fixing end of fast mechanism, 14 upper end of gear ring are connect by bolt with upper box 12, and 14 lower end of gear ring passes through bolt and lower box 15
Connection, the torque for finally carrying out planetary gear speed reducing mechanism for output terminal by planet carrier 13 export.The lower connecting pin of 13 lower end of planet carrier
131 can save land for casing one to be saved one with inbuilt casing is needed to be attached and are sequentially sent to what is formed after drilling rod 3 is applied and bored
Deeper drill hole.Upper box 12 and lower box 15 connect fixation with 9 one end of bracket, make its stress big, ensure that using the longevity
Life.
The inner wall of sun wheel shaft 26 sets a strengthening segment 261, and the wall thickness at strengthening segment 261 is more than the interior wall thickness of other positions
Degree, strengthening segment 261 are located at planet carrier 13 and 14 matched position of gear ring, hollow sun wheel shaft 26 are enable more reliably to carry
With transmission torque.It is used between strengthening segment 261 and the inner wall on periphery and seamlessly transits to form integrally connected.Sun wheel shaft 26 it is hollow
Axis interior diameter is ranging between 300 millimeters to 800 millimeters.
Since 7 inner space of torque case is limited, intensity, the use demand in service life should be met in torque case 7, is made again
Standard component bearing can form good cooperation with internal structural space, and therefore, the structure type of transmission can not meet.Planetary gear
27 are fixed on by planetary gear axis pin 24 and planet wheel bearing 23 on planet carrier 13, upper connecting pin 132, lower connecting pin 131 it is interior
Clamping setting one is placed on the bearing 21 in sun wheel shaft 26, upper connecting pin 132, lower connecting pin respectively between side and sun wheel shaft 26
Clamping setting one is placed on connecting pin 132, on lower connecting pin 131 respectively between 131 outside and upper box 12 and lower box 12
Bearing 22, planet carrier 13 is fixed by bearing 21, bearing 22, the bearings 22 of upper and lower ends by seal receptacle 16 into
Row axial restraint, the seal receptacle 16 of upper and lower ends are separately fixed on upper box 12 and lower box 15, seal receptacle 16 and upper connection
It is sealed between end 132, lower connecting pin 131 using sealing 17;The bearing 21 of upper end carries out axial restraint by seal receptacle 25,
Seal receptacle 25 is fixed on connecting pin 132, is sealed between seal receptacle 25 and sun wheel shaft 26 by sealing;The axis of lower end
It holds 21 and axial restraint is carried out by seal receptacle 19, wherein the bearing 21 positioned at lower end is also fixed on planet carrier by limiting device 18
In 13, limiting device 18 is sectional design, is carried out by the seal receptacle 19 being arranged on lower 131 madial wall of connecting pin radially solid
It is fixed.It is sealed between seal receptacle 19 and sun wheel shaft 26 by sealing 20.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformation can also be made, these are improved and deformation
Also it should be regarded as protection scope of the present invention.
