Abstract
The utility model relates to a screw pile machine power head which mainly comprises DC motors, planetary speed reducers and a three-ring speed reducer, wherein the two planetary speed reducers are mounted at the input shaft end of the three-ring speed reducer; the DC motors are mounted on the planetary speed reducers and used for driving the planetary speed reducers to operate and drive the three-ring speed reducer to rotate; and the three-ring speed reducer is used for driving a drill rod to work. In the utility model, the characteristic of constant torque of the DC motors is fully utilized to adjust a rotational speed so as to achieve the purpose of stable speed adjustment. The screw pile machine power head has the advantages that the structure is simple and reasonable, the connection is convenient, high torque is output, the rotational speed is adjustable, and output torque can not descend with the reduction of the output rotational speed. Therefore, the screw pile machine power head is an ideal screw pile machine power head.
Description
Technical field
The utility model relates to a kind of mechanomotive force device, the unit head of a kind of specifically special drive screw stake machine drill bar work.
Background technology
We know, along with the continuous development of China's building trade and pile foundation industry, and the domestic construction floor constantly to high-rise, superelevation layer development, require the degree of depth of stake more and more darker.At present, unit head on the screw rod stake machine generally adopts ac motor, because the stake that screw rod stake machine forms is a kind of compaction pile, be not unearthed in the process of pile, need bigger output torque, also need in the construction to adjust output speed according to the situation in place, therefore, ac motor is when the needs speed governing, and his output torque also descends along with the lower of rotating speed, can not satisfy the construction needs.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of simple structure, reasonable is provided, easy to connect, output torque is big, rotating speed is adjustable, output is changeed apart from can be along with output speed reduces and the new screw stake mechanomotive force head that descends.
The technical scheme in the invention for solving the above technical problem is: a kind of screw rod stake mechanomotive force head, it is characterized in that: it mainly is made of dc motor, planetary reducer, three-ring gear reducer, two planetary reducers are installed in the input shaft end of three-ring gear reducer, dc motor is installed on the planetary reducer, drive the planetary reducer running with dc motor, drive three-ring gear reducer and rotate.Three-ring gear reducer drives drilling rod work.
The utility model adopts dc motor, makes full use of the characteristic of the permanent torque of dc motor, is used for adjusting rotating speed, reaches the purpose of smoothly adjustable-speed.Against existing technologies, the utility model simple structure, reasonable, easy to connect, quick, transfer torque is big, handling ease, output is changeed apart from can and not descending along with the output speed reduction, is a kind of desirable screw rod stake mechanomotive force head.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. dc motors among the figure, 2. planetary reducer, 3. three-ring gear reducer.
The specific embodiment
As can be seen from Figure 1, a kind of screw rod stake mechanomotive force head, it mainly is made of dc motor 1, planetary reducer 2, three-ring gear reducer 3, two planetary reducers are installed in the input shaft end of three-ring gear reducer, dc motor is installed on the planetary reducer, drive the planetary reducer running with dc motor, drive three-ring gear reducer and rotate, three-ring gear reducer drives drilling rod work.The said dc motor 1 of the utility model, planetary reducer 2, three-ring gear reducer 3 all are commercial, and it is specifically formed, structure belongs to prior art.
The utility model adopts dc motor, since dc motor have good governor control characteristics, overload capacity big, can bear frequent impact load, do not have extremely fast start, the output torque when reducing rotating speed is characteristics such as permanent torque, make full use of the characteristic of the permanent torque of dc motor, be used for adjusting rotating speed, reach the purpose of smoothly adjustable-speed.Screw rod stake machine output speed so the centre has increased one-level planetary reducer 2, has reduced the output speed of electric direct current motivation 1 at 4-8 rev/min, has increased output torque.Be connected with three-ring gear reducer 3 with planetary reducer 2, drive the work of drilling rod at last by three-ring gear reducer.The utility model simple structure, reasonable, easy to connect, quick, transfer torque is big, handling ease, output is changeed apart from can and not descending along with the output speed reduction, is a kind of desirable screw rod stake mechanomotive force head.
