Embodiment Construction

[0032] Such as Figure 1~6 Among them, a conductive slip ring, including:

[0033] The fixed disk 1 is used to connect with the fixed component and connect with the electric input;

[0034] Rotary disk 2, the rotary disk 2 is rotatably installed in the fixed disk 1, the conductive connection between the rotary disk 2 and the fixed disk 1, and the rotary disk 2 is connected to the electrical output;

[0035] The shaft fixing ring 3 is used for fixed connection with the rotating parts, and the shaft fixing ring 3 is connected with the rotary disk 2 . Based on this structure, by adopting a disk-shaped structure, the thickness of the entire conductive slip ring in this example is less than 1 / 3 of the diameter. Therefore, it is convenient to be installed at the position of the output shaft 15 between the reducer 8 and the crank 9, occupies a small space, and is convenient for modifying existing equipment.

[0036] The preferred solution is as Figure 1~3 Among them, a concave c...

Abstract

The invention provides a conductive slip ring comprising a fixing disc which is used for being connected with a fixing component and connected with electric input; a rotary disc which can be rotatably installed in the fixing disc, wherein the rotary disc and the fixing disc are conductively connected and the rotary disc is connected with electric output; and a shaft fixing ring which is used for being fixedly connected with a rotary part and connected with the rotary disc. As for a rotary electrode, a rotary electric brush is fixedly connected with an electrode stud, and the electrode stud is connected with one end of a fixing threaded sleeve through threads. The fixing threaded sleeve is provided with a through hole. The free end of the electrode stud is provided with internal threads. A fastening screw penetrates through the through hole to be connected with the electrode stud. The other end of the fixing threaded sleeve is provided with a connecting post. The axial installing space is reduced by using the disc structure, installation can be performed between the decelerator and the crank arm of an oil pumping unit and a power supply and control electric signals can be reliability transmitted.

Description

technical field [0001] The invention relates to the field of auxiliary accessories of oil field pumping units, in particular to a special conductive slip ring for crankshafts of oil field pumping units. Background technique [0002] Adjusting the position of the crank balance weight is one of the effective methods to improve the efficiency of the pumping unit system in the oil field. Chinese patent document CN104712293A records "a real-time adjustment device for an auxiliary balance weight of a pumping unit" which can realize the balance adjustment of the crank of the pumping unit and realize the automatic adjustment and control of the balance weight. To ensure the normal operation of the mechanism, the power supply and the transmission of control electrical signals are prerequisites. Considering the continuous rotation of the crank member of the pumping unit, the traditional power supply method will inevitably cause problems such as winding and knotting, and a conductive s...
