Embodiment Construction
[0020] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0021] As described in the background art, the safety factor of the beam pumping unit in the prior art is relatively low. In order to solve the above technical problems, the present invention provides a beam pumping unit, such as figure 1 As shown, it includes: a base 100; a bracket 200; and a beam 300, the beam 300 is connected to the base 100 through the bracket 200, one end of the beam 300 is a balance weight end 101, and the other end of the beam 300 is an oil pumping end 102; a beam positioning device for positioning the beam 300 relative to the base 100 is provided between the oil pumping end 102 of the beam 300 and the base 100, the beam positioning device includes: a support part 110 h...

The invention provides a beam-pumping unit. The beam-pumping unit comprises a base, a support and a walking beam which is connected with the base through the support. One end of the walking beam is a counterweight end. The other end of the walking beam is an oil pumping end. A walking beam locating device used for relative locating of the walking beam and the base is arranged between the oil pumping end of the walking beam and the base. The walking beam locating device comprises a support part, a first connection part and a second connection part. The support part is provided with a first end and a second end far away from the first end. The oil pumping end is connected with the support end through the first connection part. The base is connected with the support end through the second connection part. The walking beam locating device can achieve a locating function between the base and the walking beam, thus the problem that the safety factor of a beam-pumping unit in the prior art is low is solved, the effect that even if the walking beam is in the brake failure state, the swing falling phenomenon caused by partial weight does not appear is achieved, and thus the beam-pumping unit is safer and securer.
Description
technical field [0001] The invention relates to the mechanical field, in particular to a beam pumping unit. Background technique [0002] The beam pumping unit is a pumping unit that contains a beam, is reversed by a connecting rod mechanism, and is balanced by a crank weight. As the main transmission component of the pumping unit, the beam is installed on the bracket bearing, one end is the oil pumping load, and the other end is the balance weight load. For the up and down movement of the donkey's head. In order to prevent the unbalanced beam of the pumping unit in non-working conditions such as installation, commissioning, inspection, maintenance, and replacement of parts, a brake device is installed on the pumping unit, and it is clearly stipulated in the pumping unit safety operating procedures : Any operation carried out on the pumping unit must be carried out under the state of the parking brake, so as to prevent the beam from falling under the heavy state and cause ...
