Abstract

The utility model relates to a reversing control system of a hoist type pumping unit. The reversing control system of the hoist type pumping unit is characterized in that a chain wheel is arranged at the center of the end face of a hoist wheel, the chain wheel is connected with the other chain wheel through a chain, a clamping plate is arranged in the middle of the upper section of the chain, two iron plates are clamped by the clamping plate, a permanent magnet is arranged on the outer sides of the iron plates, bearings are mounted beneath the iron plates, a support is arranged below the bearings, and a proximity switch is mounted on one side of the middle part where the permanent magnet makes reciprocating motion. The reversing control system of the hoist type pumping unit has the advantages of being simple in structure, accurate and reliable in long-time running of signals, convenient to maintain and repair and the like.

Description

Winding type oil pumper reversing control system
Technical field
The utility model belongs to oil recovery machiner technical field, and specifically, what it related to is winding type oil pumper reversing control system.
Background technology
In recent years, oil field at home industry has been developed multiple tower shelf type oil pumping machine, its common ground is that ballast box is all to rely on two slideways to support to move up and down, the sensitive switch of controlling motor commutation is contained in the certain altitude position of frame, when dependence is contained in permanent magnet on ballast box by sensitive switch to magnetic force signal of switch, pass to the control system of electric control box through switch, realize motor commutation control.This device is also reliable in the oil pumper starting stage, but along with time lengthening, and the pulley of ballast box and the increase of the wearing clearance of slideway cause magnet on ballast box and the distance of sensitive switch change and occur the situation that signal is inaccurate.
Summary of the invention
The purpose of this utility model, for the problem of above-mentioned prior art, provides a kind of simple in structure, and accurately and reliably, maintenance is winding type oil pumper reversing control system easily for the long-term operation of signal.
For this purpose, the present invention adopts following technical scheme:
A kind of winding type oil pumper reversing control system, it is characterized in that: a sprocket wheel is equipped with at the end face center of elevator wheel, connect with another sprocket wheel by chain, in the middle of the epimere of chain, be provided with clamping plate, two iron plates of clamping plate clamping, permanent magnet is equipped with in the outside of iron plate, and bearing is installed in the below of iron plate, bearing below is provided with support, and in the reciprocating centre position of permanent magnet, one side is installed approach switch.
The utlity model has simple in structure, the long-term operation of signal accurately and reliably, the feature such as maintenance is convenient.
Accompanying drawing explanation
Fig. 1 is the utility model structural principle schematic diagram.
Fig. 2 is the utility model side-looking principle schematic.
Number in the figure: 1. elevator wheel, 2. sprocket wheel, 3. chain, 4. clamping plate, 5. permanent magnet, 6. bearing, 7. support, 8. approach switch.
The specific embodiment
According to Fig. 1, Fig. 2, a sprocket wheel [2] is equipped with at the end face center of elevator wheel [1], connect with another sprocket wheel [3] by chain [3], forming a chain [2] moves reciprocatingly along with elevator wheel [1] forward and reverse running, in the middle of the epimere of chain [3], be provided with clamping plate [4], two iron plates of clamping plate [4] clamping, permanent magnet [5] is equipped with in the outside of iron plate, 2 bearings [6] are installed in the below of iron plate, bearing [6] below is provided with support [7], support [7] is provided with slideway, bearing [6] can slide in slideway, in the reciprocating centre position of permanent magnet [5], one side is installed approach switch [8], permanent magnet [5] is adjustable with the distance of approach switch [8], after adjusting to optimum distance, keep remaining unchanged for a long period of time.
When work, permanent magnet [5] is along with elevator wheel [1] is positive and negative then move reciprocatingly, and when permanent magnet [5] is during by approach switch [8], gives [8] magnetic force signals of approach switch, and this signal is passed to the control system of electric control box through switch, complete motor commutation instruction.
