[0041] The present invention will be described in detail below in conjunction with each of the drawings.
[0042] Append figure 1 , 2 3, 4, and 5, a cable-free wax robot, including a power system, a crawling shaft 11, a helper rod 6, a wraper knife 5, and a roller 1, and the crawling shaft 11 and the support rod 6 are directly or indirectly directly or The power system is fitted together, the power system is used to drive the crawler 11 rotation, and the wiper blade 5 is mounted on the support rod 6, and the roller 1 is directly or indirectly mounted on the side wall of the crawler 11.
[0043] In this clearing robot, by combining the power system, the crawling shaft 11, the helper rod 6, the wax knife 5 and the roller 1 are formed, and the robot can be down-down in the tubing 20, the process of the robot is on the process In the middle, the worm 5 can scrape the wax on the tube wall, and the operating efficiency is high.
[0044] The method of the specific operation is as follows, first put the entire robot into the tubing 20, the roller 1 tighten the inner wall of the oil pipe 20, the power system starts working, the power system drives the crawler 11 to rotate, followed by the roller 1 with the crawler 11 A relative rotation occurs between the tubing 20, and the rotation of the roller 1 drives the entire robot to move in the tubing 20, thereby driving the wiper blade 5 to move along the inner wall of the tubing 20. Implement cable waxing robot clear waxes, saving costs and artificial.
[0045] Further, it is to be further illustrated in this configuration, the wiper blade 5 is a scratch-shaped wrapping knife 5, and the wiper blade 5 rotates on the support rod 6, the center axis of the cutting knife 5 and the central axis of the support rod 6. The wavy wavar 5 can be rotated about the support rod 6, or may be moved along the support rod 6, so that the probability of being caught by the cavalry 5 is lowered during wharsing.
[0046] Append figure 1 and 2 As shown, the mounting plate 10, the holder 8, the adjustment spring 7, and the adjusting screw 9 are also included. The mounting plate 10 is mounted on the side wall of the crawler 11 by the adjustment screw 9, and the adjustment spring 7 is set to the adjusting screw 9, and the spring The two ends are respectively opposite the mounting plate 10 and the crawler 11, and the bracket 8 is mounted on the mounting plate 10, and the roller 1 is rotated to be mounted on the bracket 8.
[0047] The roller 1 is mounted on the bracket 8 of the mounting plate 10, and the distance between the mounting plate 10 and the crawling shaft 11 can be changed by twisting the adjusting screw 9, so the distance between the roller 1 and the reptile shaft 11 side wall is Adjusting, and the distance between the roller 1 and the reptile shaft 11 side wall also has a certain scalability, and the height of the reptile pressure tube 20 in the inner wall of the oil pipe 20 is adjusted by the adjustment screw 9 before the lower well. The elastic force is consistent, and the motor 16 outputs power utilization maximizes. And during the process of running the robot, the adjustment spring 7 can achieve automatic telescopic. When the spring is compressed when the wax is relatively thick, it is revealed that the slider 3 can be pressed against the oil tube 20, and the maximum outer diameter of the crawler is automatically adjusted during operation, so that it can accommodate different cases of oil pipes. 20.
[0048] Append figure 1 and 3 As shown, the power system includes a housing 2, a motor 16, a coupling, a speed reducer 15, a support bearing 13, and a thrust bearing 14, and the reducer 15 are connected to the axial axis of the motor 16, and the crawler 11 passes the coupling and the reducer. 15 Phase, the coupling is provided with a thrust bearing 14 between the coupling and the crawling shaft 11, and the support bearing 13 is disposed between the crawler 11 and the outer casing 2.
[0049] The action of the motor 16 is to convert electrical energy into mechanical energy, and the reducer 15 increase the torque by reducing the speed, and transmits the crawler 11 through a coupling.
[0050] The overall structural eccentric migration leads to a decrease in energy of the motor 16, and the parts wear are exacerbated. The long-term eccentric movement is easily causing the mechanism to be caught, and the clear wax effect is deteriorated, and the motor 16 cannot withstand axial force. Therefore, the support bearing 13 and the thrust bearing 16 are designed between the motor 16 and the crawling shaft 11, the support bearing ensures the shaft concentricity, the coupling achieves different heart adjustment, and the push bearing should be supported by the shaft 14 and can remain rotated.
[0051] Append image 3 As shown, a rotary oil seal 12 is further included, and the rotating oil seal 12 is rotatably fitted to the crawler 11, and the rotating oil seal 12 is provided with one end of the outer casing 2.
[0052] In order to protect the motor 16, a rotary oil seal 12 is added at the crawler 11 to prevent the well from entering the motor chamber by the rotating crash 11.
[0053] Append image 3 As shown, the joint 18 and the capsule 19 are also included, and the joint 18 is disposed at one end of the outer casing 2, and the rotary oil seal 12 and the joint 18 are respectively located at both ends of the outer casing 2, the outer casing 2, the rotary oil seal 12, the joint 18, and the crawler 11. A motor chamber is formed together, and a sealing end head 17 for blocking the motor cavity is provided on the joint 18, and the motor 16 is located within the motor chamber, and the capsule 19 is disposed on the side of the joint 18, and the capsule 19 is connected to the motor chamber.
[0054] Because the entire robot is to work in the well, when the motor chamber and the external well fluid are pressure unbalanced, the pressure difference causes the oil seal, so that the well liquid enters the motor 16 to cause the motor 16 to damage. Therefore, in order to maintain the pressure balance of the motor cavity and the external well fluid, the fluid volume has a small impact of the temperature pressure, and the motor cavity in the motor cavity is required to be filled with clean motor 16 oil.
[0055] The specific entire robot has a multi-knock, and the outer casing is connected to the casing.
[0056] In the above, in order to further improve the pressure difference change ability of the motor chamber, the motor cavity is added to the capsule 19. When the motor 16 oil is expanded or contracted, the capsule 19 itself has thermal expansion and detachable pressure, which is the problem of balanced pressure in the capsule 19, which solves the problem of oil expansion of the motor 16 heating motor 16.
[0057] Append figure 1 and 4 As shown, it is also included, and the di-folding link 21, the slider 3, the first spring 2201, the second spring 2202, the collar, and the lock adjustment section 4 are shown, and the power system is directly or indirectly provided with joint 18, and the support rod 6 With the joint 18, the ferrule sleeve is provided on the support rod 6, and the first spring 2201 and the second spring 2202 are arranged on the support rod 6, and the first spring 2201 and the second spring 2202 are located at both ends of the link. The lock adjustment section 4 is disposed on the support rod, and both ends of the first spring 2201 respectively opposite the joint 18 and the collar, the second spring 2202, respectively, against the collar and lock adjustment elements 4, and two. The two ends of the folded link 21 are hinged together with the joint 18 and the collar, and the slider 3 rotates the bending of the two-stage folded link 21.
[0058] Take Figure 5 As shown, both the specific first spring 2201 and the second spring 2202 are in a compressed state, and the locking adjustment section 4 can be changed, and the first spring 2201 and the second spring spring can vary. The compressed state of 2202 changes, and the bend angle of the secondary fold link 21 can also be adjusted so that the distance between the slider 3 and the support rod 6 can be better adapted to different pipe diameters. The first spring 2201, the second spring 2202, the secondary folding link 21, and the slider 3 correspond to forming a supporting mechanism, which allows the supporting rod 6 to avoid distillation. At the same time, when the motor 16 rides the crawler 11 to rotate, the motor 16 generates a force consistent with the direction of rotation. If this force cannot be offset, the motor 16 will generate autocute to crawl the entire robot, and The support mechanism can generate a friction opposite to the rotation direction of the motor 16 by the tube wall of the slider 20 (attached Figure 5 In the F identity) to prevent motor 16 from rotating, so that the robot can stably crawling up and down. The pressure between the slider and the tube is identified.
[0059] Append Figure 4 and 5 As shown, the secondary folding link 21 has three, and the three two-section fold link 21 is distributed around the arc of the support rod 6, and the slider 3 is rotatably mounted on each of the two fold link 21.
[0060] Three slings 3 are as uniform distribution, the force of the spring is the same, so the angle of the bracket 8 opens, so that the entire clear wax mechanism maintains concentrically with the oil pipe 20, which acts as a mechanism.
[0061] The specific slider 3 can be a wheel or a slider, and a wheel is selected as the slider 3 in this aspect.
[0062] The specific lock adjustment section 4 can be a clamp or a retaining ring or a lock regulating nut, which is selected as the lock adjustment nut as the lock adjustment section 4 in this aspect.
[0063] It also includes a battery, a control chip, a charging module, and a wireless antenna module, a control chip and power system electrical connection, a battery and a control chip electrical connection, a charging module, and a wireless antenna module and a control chip electrical connection.
[0064] The specific battery, the control chip, the charging module, and the wireless antenna module are all in the outer casing 2. The action of the battery is the power supply, the control chip, the charging module, and the wireless antenna module form a control unit, which is a conveyance to the motor 16, According to the signal control motor 16, the signal control motor 16 is received according to the antenna, and the charge module is automatically controlled when the power supply is insufficient, and the charging module is charged to protect the battery.
[0065] Append figure 1 and 2 As shown, the roller 1 is an elliptical spherical roller 1, and the central axis of the roller 1 is not parallel to the central axis of the crawler 11.
[0066] The central axis of the roller 1 is not parallel to the central axis of the crawler 11, so that the roller 1 can generate a force of the movement of the crawling shaft 11 along the oil tube 20 when rotating. It can be rotated around the axis, and the roller 1 bracket 8 is inclined to the mounting plate 10 on 15 ° (i.e., the axis of the crawling shaft 11) is mounted on the mounting plate 10, and the entire mechanism is placed in a total of three mounting plates 10, a total of 12 rollers 1 There is a gap between the .12 rollers 1, so that the well fluid in the tubing 20 can flow between the rollers 1, so that the entire crawling robot can flow in the oil pipe 20 in the premise of the oil flow. Therefore, the wells can work normally without downtime.
