Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1 and 2, the present embodiment includes a support base 1, a tower 3 disposed on the support base 1, a belt 4, a weight box 11, and a driving system, wherein the support base 1 and the tower 3 use a pull rod to support the weight box 2, and the driving system is fixedly connected to the weight box 11. The weight of a driving system (comprising a motor 13, a speed reducer, a roller 12 and the like) is acted on the weight box 11 innovatively, so that the volume and the weight of an upper platform of a tower-type pumping unit are reduced, the integral center of gravity of a tower 3 is moved downwards, the operation is safer, when maintenance and repair are needed in the working process of the tower-type pumping unit, the pumping unit is stopped, the weight system falls to the bottom, the top platform of the pumping unit does not need to be climbed, the danger of high-altitude operation is solved, when the pumping unit is maintained, a crane does not need to be matched, the maintenance is convenient, the maintenance time and cost are saved, and the working efficiency is improved; meanwhile, the filling of the balance weight iron is reduced, and resources are saved.
