The beneficial effects of the utility model are: the utility model is set up motor and ball screw transmission mechanism on the basis of existing machinery centralizer, centralizer last carry or descending process in, can set upright support by Electric Machine Control shrinks, carry on having avoided or descending process in friction and clamping stagnation, thereby prolonged application life of centralizer.
Description of drawings
Fig. 1 is a main sectional view of the present utility model.
The specific embodiment
As shown in Figure 1, present embodiment has mechanical erection device 1, the one end is connected with the ball screw transmission mechanism by pull bar 2, this ball screw transmission mechanism other end is connected with motor 4, ball screw transmission mechanism and motor 4 overcoat pressure-bearing pipes 5, pull bar 2 is with mechanical erection device 1 coaxial arrangement and run through whole mechanical erection device 1, is fixed for controlling the slide block 3 of mechanical erection device 1 action on the pull bar 2.
Described mechanical erection device 1 comprises the center tap 1-1 that is connected with pressure-bearing pipe 5, this center tap other end connects the slide-bar 1-2 of diameter less than center tap 1-1, the terminal lower contact 1-3 that connects of slide-bar 1-2, slide-bar 1-2 overcoat can be along the upper sliding sleeve 1-4 and the low sleeve 1-5 of its slip, between upper sliding sleeve 1-4 and the center tap 1-1 compression spring 1-6 is set, between low sleeve 1-5 and the lower contact 1-3 stage clip 1-7 is set down, evenly be provided with one group on described upper sliding sleeve 1-4 and the low sleeve 1-5 and set upright support 1-8, it is hinged with upper sliding sleeve 1-4 and low sleeve 1-5 respectively to set upright support 1-8 two ends, have a through hole 1-9 for slide block 3 slips near center tap 1-1 one side in the middle of the described slide-bar 1-2, this through hole is by the axis of slide-bar 1-2, and the height of described slide block 3 is greater than the diameter of slide-bar 1-2.
Described ball screw transmission mechanism comprises ball screw 6 and the nut 7 that cooperatively interacts, and ball screw 6 inputs are connected with motor 4 by shaft coupling 8, and nut 7 outputs are fixedlyed connected with pull bar 2.
The operating principle of present embodiment is: during use, at first supply positive electricity through motor 4 on ground, motor 4 is just changeing, drive pull bar 2 actions by the ball screw transmission mechanism, the pulling slide block moves to center tap 1-1 direction, also moves to center tap 1-1 direction thereby drive upper sliding sleeve 1-4, makes to set upright support 1-8 contraction, instrument is lowered in the oil well, centralizer and the borehole wall did not contact all the time and were convenient to carry or descending this moment again; When arriving the operating position, give motor 4 for negative electricity again, the counter-rotation motor, drive pull bar 2 actions by the ball screw transmission mechanism, promoting slide block moves to lower contact 1-3 direction, also move thereby drive upper sliding sleeve 1-4, make and set upright support 1-8 and open, set upright support 1-8 and compress with the borehole wall and contacted centralizing function to lower contact 1-3 direction.Open different-diameter and obtain different contact pressures, can adjust spacing position (promptly controlling stroke) as required and adjust pressure.On end-of-job needs, carry or during descending instrument, make for again motor 4 for positive electricity and set upright support 1-8 external diameter and shrink.When slide block 3 unclamps, it is open by compression spring 1-6 and following stage clip 1-7 pressure setting upright support 1-8, not to promote by slide block 3, so when motor 4 or ball screw transmission mechanism are malfunctioning, this electronic centralizer is equivalent to the standard machinery centralizer, can more than carry or descending, can stuckly can from well, not take out yet.
