Problems solved by technology

[0003] 1. First, it is very difficult to achieve a super long stroke (such as 10-20m);
[0004] 2. The second is that the weight of the counterweight box is too heavy. For example, the weight of the counterweight box is 8.5 to 10 tons for the existing tower pumping unit with a suspension point load of 12 tons;

Abstract

The invention discloses a tractor tower type pumping unit device. A tractor assembly consists of a three-phase asynchronous motor, a speed reducer, a brake, a weight box and a guiding wheel assembly. The three-phase asynchronous motor drives two driving gears to rotate through the speed reducer; and the two driving gears are respectively engaged with two rack rails and purely roll on the gears so as to drive the whole tractor assembly to reciprocate up and down along a horizontal guide rail. The tractor assembly pulls a pumping rod to reciprocate up and down in a pumping unit through a chain, and the pumping rod ascends to be in a pumping stroke and descends to be in an idle stroke. The invention provides a pumping unit product which can realize an overlong stroke and greatly save the counterweight. The pumping unit device has the advantages of compact structure and stable operation, and realizes the overlong stroke of 10 to 20m. The weight of the motor and speed reducer acts as a part of counterweight. For example, a tractor tower type pumping unit with the suspension point load of 12 tons can save the counterweight of 4 to 5 tons and is widely applied to oil production.

Description

technical field [0001] The invention relates to the field of oil extraction pumping units, in particular to a tractor tower type pumping unit device. Background technique [0002] The existing tower pumping unit product mainly has the following defects: [0003] 1. First, it is very difficult to achieve a super long stroke (such as 10-20m); [0004] 2. The second is that the weight of the counterweight box is too heavy. For example, the weight of the counterweight box is 8.5 to 10 tons for the existing tower pumping unit with a suspension point load of 12 tons; Contents of the invention [0005] The purpose of the present invention is to provide a tractor tower pumping unit with compact structure, stable operation, super long stroke and a part of counterweight reduction. [0006] In order to overcome the deficiencies in the prior art, the technical solution of the present invention is to solve in this way: a kind of tractor tower pumping unit device, by tractor assembly,...
