Abstract
The utility model discloses a power head reducer of a screw pile machine. The power head reducer is composed of a pile driving frame, a thread drill rod and a power head reducer body. According to the power head reducer body, two input shafts are respectively provided with two prime motors. The prime motors drive a bevel gear pair in the reducer body to rotate in a connecting mode. The bevel gear pair drives an output shaft in a connecting mode. The output shaft is connected with and drives the thread drill rod to drill or retreat in a rotating mode. The bevel gear pair drives an output shaft gear in a connecting mode at the same time. The output shaft gear is meshed with a fixing rack on a stand column of the pile driving frame. According to the forced synchronization principle of gear and rack transmission, the power head reducer of the screw pile machine has the advantages that matching of the rotating speed and the lifting speed of the power head reducer is ensured, and the structure is simple.
Description
Technical field
The utility model belongs to the engineering mechanical device technical field, relates to a kind of screw pile machine power head reductor.
Background technology
Screw rod pile machine, as a kind of emerging piling machinery, has good development prospect; But during the stake of screw rod pile mechanism, current maximum bottleneck is that unit head reductor speed of gyration and hoist engine promote, the difficulty of matching of pressing speed is large, require dynamic head main spindle often to rotate a circle, the unit head reductor drives drilling rod 1 pitch that must promote or descend, otherwise the destroyed screw rod pile that do not become of screw thread.Traditional solution is mainly to coordinate unit head and hoist engine to reach the coupling of both speed by electrical control system at present.This mode cost is higher, and pile quality affects greatly by geologic(al) factor, and pile quality is undesirable.
Summary of the invention
The purpose of this utility model in the deficiency with improving prior art, provide a kind of application of principle of the forced synchronism by the rack-and-pinion transmission to the screw pile machine power head reductor, guarantee the revolution of unit head reductor and the coupling of rising or falling speed, screw pile machine power head reductor simple in structure.
The purpose of this utility model is to realize like this, a kind of screw pile machine power head reductor, by pile driving frame, threaded drillpipe and unit head reductor, formed, be characterized in that described unit head reductor is to be separately installed with two prime mover on two power shafts, prime mover connects drive reductor female cone gear pair and rotates, taper gear pair connects the drive output shaft, output shaft connects drive threaded drillpipe rotary drilling or exits, taper gear pair connects the drive output shaft gear simultaneously, and output shaft gear is meshed with the stationary rack on the pile driving frame column.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model unit head reductor is to be separately installed with two prime mover on two power shafts, prime mover connects drive reductor female cone gear pair and rotates, taper gear pair connects the drive output shaft, output shaft connects drive threaded drillpipe rotary drilling or exits, taper gear pair connects the drive output shaft gear simultaneously, output shaft gear is meshed with the stationary rack on the pile driving frame column, whole unit head reductor can slide up and down along stake machine column rack guide rail, power is from the output gear shaft of reductor own and the engagement of stake machine column upper rack, the output main shaft drives the threaded drillpipe rotary drilling simultaneously, form screw rod pile, the utility model is to adopt rotary drilling and promote two kinds of methods for designing that power source is integrated in one of pressurization, technical data according to threaded drillpipe, two kinds of output speeds of reductor are complementary with it to design gearratio, utilize this principle, this unit head reductor and pile driving frame are used in conjunction with, because gearratio is complementary and fixes, so can guarantee accurately that the unit head speed reducer output shaft often rotates a circle, the unit head reductor can be on stake machine column promotes or the distance of the drilling rod pitch that descends along rack guide rail, so just can form a complete screw rod pile, can accurately complete the construction of screw rod pile.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
A kind of structural principle schematic diagram that Fig. 2 is the utility model unit head reductor.
The specific embodiment
Embodiment, a kind of screw pile machine power head reductor, with reference to Fig. 1, to be provided with unit head reductor 4 at the top of pile driving frame 5, unit head reductor 4 is to be separately installed with two prime mover on two power shafts 2, prime mover connects drive reductor female cone gear pair and rotates, taper gear pair connects drive output shaft 1, output shaft 1 connects drive threaded drillpipe 6 rotary drillings or exits, taper gear pair connects drive output shaft gear 3 simultaneously, output shaft gear 3 is meshed with the stationary rack 7 on the pile driving frame column, and this forms a kind of structure of the present utility model.
Operating principle of the present utility model is: two prime mover are installed on every power shaft 2, driving reductor female cone gear pair rotates, send low-speed big to output shaft 1, band is automatically connected in threaded drillpipe 6 rotary drillings on output shaft 1 or exits, power is sent to output shaft gear 3 simultaneously, output shaft gear 3 by with the pile driving frame column on stationary rack 7 be meshed, produce power downward or upward, the creeping into or exiting of matching thread drilling rod 6, because gearratio is complementary and fixes, so can guarantee accurately that unit head speed reducer output shaft 1 often rotates a circle, unit head reductor 4 can be on stake machine column promotes or the distance of the drilling rod pitch that descends along guide rail, so just can form a complete screw rod pile.
