Embodiment Construction

[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] Such as figure 1 with figure 2 As shown, this embodiment includes a support base 1, a tower 3 arranged on the support base 1, a belt 4, a counterweight box 11 and a drive system, the support base 1 and the tower 3 are supported by pull rods 2, the described The driving system is fixedly connected with the counterweight box 11. The innovation of the present invention acts on the weight box 11 by the weight of the driving system (including the motor 13, the reduction gear, the drum 12, etc.), which reduces the volume and weight of the platform on the tower ...

Abstract

The invention relates to the technical field of oil field oil extraction, and discloses a tower type pumping unit. The tower type pumping unit comprises a supporting base, a tower arranged on the supporting base, a belt, a weight box and a driving system, wherein the driving system is fixedly connected to the weight box, a front guide wheel, a rear guide wheel, a front belt fixing clamp and a rearbelt fixing clamp are fixedly installed on a platform, a reversing movable pulley is arranged below the tower platform, the driving system comprises a motor and a roller, one end of the belt is fixedto the rear belt fixing clamp, the other end of the belt bypasses the roller from bottom to top, bypasses the upper portions of the rear guide wheel and the front guide wheel, then bypasses the reversing movable pulley from top to bottom and then is fixed to the front belt fixing clamp. According to the tower type pumping unit, the danger of high-altitude operation is avoided, when the pumping unit is in maintenance operation, a crane does not need for cooperation, maintenance is convenient, the maintenance time and cost are saved, the working efficiency is improved, and the weights of the driving system and a speed reducing device act on the weight box, so that the filling of counterweight iron is reduced, and resources are saved.

Description

technical field [0001] The invention relates to the technical field of oil recovery in oil fields, and discloses a tower pumping unit. Background technique [0002] Oilfield oil production mainly adopts mechanical oil recovery equipment, among which the pumping units are mainly beam pumping units and tower pumping units. The tower pumping unit is characterized by its simple structure, basically maintenance-free, long stroke, low The performance of the load can be widely used, but the height of the pumping unit tower is more than ten meters, and its drive system is an electric motor and a power drum with a reduction mechanism. They are all set on the top platform of the tower pumping unit. During the working process of the pumping unit, the driving system needs to be maintained and overhauled frequently. The maintenance workers need to climb to the top platform which is more than ten meters high. The limited space of the top platform also brings inconvenience to the overhaul ...
