Embodiment Construction
[0051] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0052] combine Figure 1-Figure 3 , The power lowering tower pumping unit of this preferred embodiment includes a base 1, a tower 3, a power system 2 connected to the base 1, a front sling traction system and a rear sling traction system. The tower 3 is a combined structure, which is connected by multiple tower sections, and the tower section can be increased or decreased according to site requirements to raise or lower the height of the tower; or the tower is set as an integral structure, and the frame is an integral In the structure, there is no need to disassemble and assemble, which simplifies the construction procedure and is suitable for low tower occasions.
[0053] Among them, such as Figure 4 , the power system 2 includes a sequentially connected motor 13, a planetary cycloid reducer 17 and a reel 21; the input end of the motor 13 a...
