[0010] Five, specific embodiment: the present invention will be further described below in conjunction with accompanying drawing:
[0011] figure 1 It is a structural schematic diagram of the present invention. As shown in the figure, the dual-motor cam-type measuring and adjusting arm of the water injection well measuring and adjusting instrument includes a pipe groove main body 1, a decelerating motor 2, a pop-up and retracting mechanism for the docking arm, a limit connecting rod 15 and a docking Arm, pipe groove main body 1 is provided with the cavity that can accommodate deceleration motor 2, pop-up arm pop-up retracting mechanism and docking arm three, makes pop-up arm retractable and can enter the cavity interior of pipe groove main body 1. The reduction motor 2 drives the ejection arm ejection retraction mechanism to realize the ejection and retraction actions of the docking arm through the limit connecting rod 15 . The geared motor 2 is located on the upper part of t...

The invention discloses a double-motor cam type debugging arm of a water injection well debugger. The device comprises a pipe chase main body, a speed reducing motor, a butting arm bouncing and withdrawing mechanism, a limiting connecting rod and a butting arm, wherein the pipe chase main body is provided with an accommodating cavity which can accommodate the speed reducing motor, a bounce arm bouncing and withdrawing mechanism and the butting arm; the speed reducing motor is used for driving the bounce arm bouncing and withdrawing mechanism to realize bouncing and withdrawing action of the butting arm through the limiting connecting rod; and the bounce arm bouncing and withdrawing mechanism is used for accurately controlling the action of the butting arm through a cam and a limiting pull rod. In the debugging arm, the bounce and the withdrawal of the bounce arm are controlled through the cam and a spring; meanwhile, the movement of a butting component is limited by using the limiting pull rod; the travel distance of the limiting pull rod is accurately controlled by the length of a limiting groove; and thus, double insurance is formed for accurate butting of the butting component, the control accuracy is high, and the butting arm always has bounce tendency under the action of a stretched irregularly-shaped spring to prevent a dead point from occurring during bounce.
Description
technical field [0001] The invention relates to a docking device for a water injection well measuring and adjusting instrument, in particular to a double motor cam type measuring and adjusting arm of the water injection well measuring and adjusting instrument. Background technique [0002] At present, the measuring and adjusting instruments for flow control of water injection wells in oil fields are mainly single-motor with rope structure, and the ejection and retraction of the docking arm are realized by using the wire rope. However, due to the narrow space of the instrument itself, the steel wire rope should not be too thick. Therefore, when the docking mechanism moves to the limit position or encounters a jam, the steel wire rope is easily broken, and maintenance is very troublesome; the steel wire rope is easy to interfere with other mechanisms. In addition, because the steel wire rope can only When the tension is generated, the docking mechanism can only rely on the tor...
