Embodiment Construction

[0036] Pumping unit system embodiment:

[0037] This embodiment provides a pumping unit system, including: a pumping unit and a safety protection device for the pumping unit. First, briefly introduce the structure of the pumping unit, such as figure 1 As shown, the pumping unit includes: a burner head 1, a beam 2, a crank 3, a balance weight 4, a base 5, a reduction box 6, a motor 7 and a circuit control device 8.

[0038] The safety protection device of the pumping unit includes a beam sensing module, a control module, a brake, a power supply switch and a power supply control circuit.

[0039] Wherein, the control module takes a programmable logic controller (PLC) as an example, such as Siemens 200 programmable controller, and of course, the control module can also be other types of controllers, such as a single-chip microcomputer.

[0040] The number of beam sensing modules is at least one. The beam sensing module, also known as the beam interrupting sensor, includes two ...

Abstract

The invention relates to an oil pumping unit system and an oil pumping unit safety protection device. The oil pumping unit system comprises an oil pumping unit and the oil pumping unit safety protection device; the oil pumping unit safety protection device comprises at least one light beam induction module, a control module, a power supply switch arranged on a power supply line of the oil pumping unit, and a brake used for controlling the oil pumping unit to brake and stop; the detection signal output end of each light beam induction module is connected with the control module through an intermediate relay; the control module is in control connection with the power supply switch and the brake; and when the light beam induction modules monitor objects, the oil pumping unit is controlled to stop power supply and stop. Thus, the malignant injury event caused when people enter the movement space of the oil pumping unit by mistake can be effectively avoided, personnel safety is guaranteed, and safety is high.

Description

technical field [0001] The invention relates to a pumping unit system and a safety protection device for the pumping unit. Background technique [0002] The pumping unit generally works in the open-air area of ​​the oil field. During the operation, someone will enter the pumping unit by mistake, causing vicious injuries to people by the balance weight and the crank. This not only poses a serious threat to the safety of personnel, but also affects the normal production of the oil field. . In order to solve this safety problem, most of the current safety protection measures are to install metal guardrails and belt guards on both sides of the pumping unit. However, most of the metal guardrails and belt guards have large gaps, and personnel may come from these There are still potential safety hazards if the gap passes through, and the metal structure of the metal guardrail is easy to corrode and has a limited service life. Moreover, the metal guardrail and belt guard can only p...
