Description
The utility model relates to the device that a kind of auger machine is used for driving drilling rod, particularly a kind of new Type of Hydraulic auger machine unit head.
Unit head is the key working part of auger machine, and its performance quality directly influences the performance of auger complete machine performance.At present require auger big in the construction to output torque, high efficiency, reliable operation, noise pollution is little etc., and direction develops, and this at first solves the unit head problem with regard to requiring.Introduction according to " pile foundation engineering " chapter 7 second joint, domestic existing auger machine mainly adopts the mechanical power head, type of belt drive is: power source generally is motor or motor, its power drags speed-changing gear box through fluid torque-converter, pass to drilling rod through universal drive shaft, bevel gear, drag augers.This mechanical power head, transmission chain length, complex structure; Because used universal drive shaft, bevel gear transmission, so transmission efficiency is not high, rotational noise is big again; Speed-changing gear box can only be realized step speed change, can not automatically change moment of torsion and rotating speed according to geological conditions; Only depend on friction to transmit plus-pressure between unit head and the drilling rod, plus-pressure is little, has reduced the complete machine operating efficiency.
The useful novel purpose of this reality provides a kind of compact conformation, and easy to operate, driving torque is big, operating efficiency height, the new Type of Hydraulic auger machine unit head that noise is low.It can produce the auger required driving torque, and can effectively transmit the plus-pressure to drilling rod, also can automatically change moment of torsion and rotating speed according to the variation of geological conditions.
The purpose of this utility model is achieved in that this unit head comprises that mainly two are set with the folk art term reductor of hydraulic variable motor, this two covers folk art term reductor all is installed in the bearing of unit head upper box, its output is equipped with pinion respectively, drives a gear wheel that is fixed on the hollow shaft jointly; Hollow shaft is supported in the upper and lower casing by two big bearings; The hollow shaft below is connected with and articulates body.
Described hydraulic variable motor can change its discharge capacity and pressure automatically according to geological conditions, thereby has changed output torque and rotating speed.
Described folk art term reductor adopts long-range hydraulic operation gear shift to realize that the low speed of auger creeps into and throwing is native at a high speed; Simple to operation, improved the operating efficiency of machine.
Described two pinions drive a gear wheel simultaneously and three gears are in same horizontal plane, the moment of torsion that the gear wheel that helps doubling can transmit; The gear centre line is an acute triangle, makes the power head structure compactness.
Described gear wheel and hollow shaft are coupled to be one; Be evenly equipped with the tooth panel of three band rectangle teeth on the hollow shaft inwall, when its tooth embedding is crept into and the outer tooth embedding on the drilling rod chimeric mutually, effectively transfer torque and plus-pressure; During the hollow shaft counter-rotating, the tooth embedding is promptly separable.
The upper and lower casing of described unit head is welded construction, and appearance profile is a closed curve that comprises three circular arcs and three tangent lines; This structure not only has enough strength and stiffness, and it is good to have technology, compact appearance, characteristics attractive in appearance.
The upper and lower casing of described unit head is with upper and lower two sleeve socket ends lid and sealing thereof, a cover separator disc and sealed separation thereof be about two chambeies so that respectively big bearing up and down is lubricated; Bearing (ball) cover has reduced the axial dimension of unit head with the shell location of big bearing.
Described articulate between body and the hollow shaft relies on screw-driving to bear axial force, relies on the boss and the groove fit transfer torque that articulates body of hollow shaft tooth panel, this structure can be reliably transfer torque downwards, expanded the purposes of unit head.
The utility model adopts two cover hydraulic variable motor and folk art term reductors, and hydraulic-driven so can automatically change moment of torsion and rotating speed according to the variation of geological conditions, realizes stepless adjustment; Use hydraulic operation, easy to operate; Two pinions drive a gear wheel, and transfer torque is big, the transmission efficiency height, and noise is low; Chimeric by hollow shaft inner teeth and the outer tooth embedding of drilling rod, can transmit plus-pressure effectively, the operating efficiency height; Compact overall structure, good looking appearance, volume is little.
Be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the upward view that removes parts such as preface 9,10,11 of Fig. 1.
1. hydraulic variable motors among the figure; 2. folk art term reductor; 3. upper box; 4. pinion; 5. gear wheel; 6. lower box; 7. hollow shaft; 20. tooth panel; 8. articulate body; 9. descend damping block; 10. hold collision body; 11. bearing pin; 12. seal one; 13. bearing (ball) cover; 14. big bearing; 15. taper pin bolt; 16. separator disc; 17. seal two; 18. supporting mass; 19. last damping block.
The embodiment of present embodiment is as follows: cooperates the location with gear wheel (5) inner ring with hollow shaft (7) shaft shoulder, the diameter of axle, gear wheel (5) is installed on hollow shaft (7), and fastening with taper pin bolt (15); Two hydraulic variable motors (1) drive two folk art term reductors (2) respectively, and two cover folk art term reductors (2) all are installed in the bearing of upper box (3), and pinion (4) is installed on folk art term reductor (2) output shaft; Separator disc (16) and sealing two (17) are contained in upper box (3) below; This moment is top box body weight (3), lower box (6) and hollow shaft (7) assembling that gear wheel (5) have been housed, and then upper box (3) and lower box (6) are separated dish (16) and are divided into two chambeies; Assemble a big bearing (14) respectively in the position of bearings in two chambeies; In bearing (ball) cover (13), be pre-loaded into sealing one (12), distinguish running in bearings end cap (13) from the hollow shaft two ends so that the position of fixation hollow axle (7) and upper box (3) and lower box (6).At hollow shaft (7) top mounting support body (18) and last damping block (19), the below is installed and is articulated body (8) and following damping block (9), use bearing pin (11) to finish at last and articulate body (8) and hold being connected of collision body (10), and in upper box (3) and lower box (6), add suitable lubrication oil (fat), then finish present embodiment.
The course of work of creeping into of unit head is: two hydraulic variable motors (1) drive two folk art term reductors (2) respectively, increase through folk art term reductor (2) 2-level reducer double reduction and to go up output torque at pinion (4) after turning round, two pinions (4) drive gear wheel (5) simultaneously, slow down to increase just can go up at hollow shaft (7) after turning round to produce driving moment.Hollow shaft (7) drives drilling rod work by the tooth panel (20) on its inwall.In unit head when work, is to drilling rod work.Plus-pressure to drilling rod during unit head work is delivered to drilling rod by casing one bearing (ball) cover one big bearing one hollow shaft, and implementation is very easy.
Use convex-concave platform transfer torque between body (8) and the hollow shaft (7) owing to articulate, articulate body (8) and can transmit operation torque, thus can hold the purposes that collision body (10) is expanded the power great waves by replacing, as descend retaining wall sleeve operation etc.
When throwing soil, only need gearshift, reduce the speed reducing ratio of speed changer, just can improve and bore village's rotating speed, realize throwing soil by folk art term reductor (2).Supporting mass (18), the effect of going up damping block (19) are the protection unit heads, reduce the top and occur producing and impact, and following damping block mainly is in order to reduce the impact of drill bit to unit head.
