Detailed description of the invention
Embodiments of the invention: as shown in Figure 1, the transmission device of a kind of intelligent pulling instrument of the present invention comprises the pulling motor 1 of the existing intelligent pulling instrument generally used, the rotary power of its main shaft is passed on transmission seal axle 3 by shaft coupling 2 by pulling motor 1, at the lower end connection for transmission square bar 4 of transmission seal axle 3, at the lower end of transmission square bar 4 suit upper driving screw rod 5, drive screw 5 can be adopted the existing structure that rotary power can be made to be converted to straight line power through switching mechanism 6(switching mechanism 6) after be connected with pulling arm 7, for controlling pulling arm 7 linear reciprocating motion, on pulling arm 7 top, retracting motor 8 is installed, the structure control pulling arm 7 of retracting motor 8 by cam 9 and torsion spring 10 is carried out opening and drawing action in.Retracting motor 8 is with moving cam 9 to rotate.When cam 9 is rotated to low spot by height point, under torsion spring 10 acts on, pulling arm 7 opens gradually; Otherwise when cam 9 is rotated to height point by low spot, pulling arm 7 draws in gradually.
In order to solve the problem of the retractable operation of motor long distance supply line, can by the lead-in wire of described retracting motor 8 with to be arranged on outside switching mechanism 6 and can stretch, the spiral winding 11 of resilience is connected, the seal socket 12 that the joint of spiral winding 11 other end is other with being arranged on transmission seal axle 3 is connected.When pulling arm 7 moves downward, spiral winding 11 is stretched; When pulling arm 7 moves upward, spiral winding 11 relies on the elasticity of self to regain.
In order to bear the end thrust that well inner high voltage produces, reducing friction, and preventing end thrust to be delivered on the main shaft of pulling motor 1, up-thrust bearing 13 can be set with in shaft coupling 2 lower end on transmission seal axle 3.In order to isolated ambient pressure, prevent medium in well from entering inside of the present invention, in the lower end of thrust bearing 13 (namely in the lower end of thrust bearing 13 and be sleeved on transmission seal axle 3), seal 14 can be installed.Seal 14, by after axial compression, produces suitable decrement, and transmission seal axle 5 outer round surface produces sealing effectiveness.
In order to improve the transmission accuracy of transmission seal axle 5, reducing the eccentric frictional force caused, can load onto at the middle part of transmission seal axle 3 cover the sliding bearing 16 be fixed on intelligent pulling tool housing 15.
In order to improve the stability that the present invention runs further, sliding tray 17 can be processed inside intelligent pulling tool housing 15, and pulling arm 7 is arranged in sliding tray 17, making pulling arm 7 can only realize linear reciprocating motion in sliding tray 17 scope.
In order to improve the stability that the present invention runs further, the spacer pin 18(preventing pulling arm 7 from rotating can be fixedly mounted contact with the pulling arm 7 drawn in by spacer pin 18 on intelligent pulling tool housing 15, rotating to prevent it).
In order to effectively ensure the reliability connected, colligation all can be carried out with fishing line and High-Voltage Insulation adhesive tape in the junction at described spiral winding 11 two ends, having made it possess enough with bonding strength and insulating properties.
In order to improve the integrally-built rigidity of the present invention, as shown in Figure 2, outer tube can be equipped outward at the main shaft of retracting motor 8, and process and assemble there is the hole of steel ball 19 on outer tube, playing supporting and reducing the effect rubbed.
Embodiments of the present invention are not limited to above-described embodiment, and the various changes made under the prerequisite not departing from invention aim all belong to the protection domain of invention.
