Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This embodiment provides a technical solution: a novel rotary pipeline robot drive section, including a motor housing 13, a motor 14 disposed inside the motor housing 13, a front drive wheel frame 2 disposed at one end of the motor housing 13, a rear drive wheel frame 16 disposed at the other end of the motor housing 13, a front motor shaft 19 disposed at the end of the motor 14 near the front drive wheel frame 2, a drive pinion 20 connected to the upper side of the front motor shaft 19, a double large gear 10 disposed below the drive pinion 20, a double small gear 9 disposed on one side of the double large gear 10, and the double large gear 10 and the double small gear 9... A rotating shaft 12 is provided inside the motor housing 9. One end of the rotating shaft 12 is fixed in a small hole on the end face of the motor front support shaft 3, and the other end is fixed in a small hole on the end face fixing block 7. It provides a rotating support shaft for the double gear. A copper sleeve 11 is fitted on the end of the rotating shaft 12 near the motor 14. The copper sleeve 11 is installed on the rotating shaft 12 and placed under the double gear to limit movement and prevent wear. Both ends of the motor housing 13 are provided with end face fixing blocks 7. Set screws 8 are provided at the contact positions between the end face fixing blocks 7 and the motor housing 13. The set screws 8 are used to fix the motor housing 13 to the end face fixing blocks 7.

[0022] The upper side of the double pinion 9 is provided with a driving gear 23. The inner side of the driving gear 23 is provided with a motor front support shaft 3. The inner side of the motor front support shaft 3 is provided with a main shaft 5. The front end of the main shaft 5 is a fixed front driving wheel frame 2, the middle is supported by two deep groove ball bearings 6, and the rear end is a driving gear 23 fixed to the shaft end, which cooperates with the double pinion 9. The double pinion 9 and the double gear 10 are integrated and fixed on the rotating shaft 12, which can rotate around the rotating shaft 12 and cooperate with the driving gear 23.

[0023] A traction ring 1 is provided at the end of the main shaft 5 away from the motor 14. The front end of the traction ring 1 is a ring-shaped pull ring, and the rear end is a threaded shaft, which is used to fix it to the front support shaft 3 of the motor. A deep groove ball bearing 6 is sleeved on the outside of the front support shaft 3 of the motor. A copper stud 22 is provided on the upper side of the front rotating shaft 19 of the motor. The outer side of the copper stud 22 is cylindrical, and the inside is threaded, which is used to connect the front support shaft 3 of the motor and the end face fixing block 7. There are three pieces in total, distributed along the circumference. The front support shaft 3 of the motor is fixed to the left side of the motor 14 with three countersunk screws, which play a supporting role for the front end component. The right side of the front support shaft 3 of the motor is disc-shaped, which can be fixed to the motor 14. The left side has a hollow shaft with a threaded opening at the end of the shaft, which can fix the traction ring 1. The center of the right disc is a driving pinion 20, and there is a gear through hole on the side of the disc, which can cooperate with the double large gear 10.

[0024] A No. 2 countersunk screw 21 is provided at one end of the copper stud 22 near the motor 14, and a No. 1 countersunk screw 24 is provided at the other end of the copper stud 22. A rear shaft 18 is provided at the end of the motor 14 away from the front shaft 19.

[0025] A rear support shaft 17 is provided at one end of the rear rotating shaft 18 of the motor. The right-end transmission component 15 is provided inside the rear drive wheel frame 16. The right-end transmission component 15 is similar to the left-end transmission system, except that there is an intermediate reversing gear between the double pinion 9 and the drive gear 23. The size and number of teeth are exactly the same as those of the double pinion 9. In this way, the rotation direction of the output spindle is opposite to that of the front rotating shaft. Other components are the same as those at the front end, including various fixed seats and bearings.

[0026] A thrust bearing 4 is provided on the side of the deep groove ball bearing 6 away from the double pinion 9. One end of the thrust bearing 4 is connected to the rotating front drive wheel frame 2, and the other end is connected to the fixed end face fixing block 7. Its function is to provide thrust to the front drive wheel frame 2. The right side of the end face fixing block 7 is a mounting plate used to fix the front support shaft 3 of the motor. The outer side can fix the motor housing 13. The thrust bearing 4 is fixed in the inner shaft of the left end face, and the middle hole is used to fix the deep groove ball bearing 6.

[0027] The working principle of the active joint of the novel rotary pipeline robot provided by this utility model is as follows: Figures 1-4As shown, during operation, motor 14 drives the driving pinion 20 to rotate via the front motor shaft 19 and the rear motor shaft 18. The driving pinion 20 engages with the double-gear 10. The rotation of the double-gear 9 drives the shaft 12 and the double-gear 9 to rotate, which in turn causes the driving gear 23 and the front motor support shaft 5 to rotate. The front motor support shaft 5 drives the front driving wheel frame 2 and the rear driving wheel frame 16 to rotate, thereby causing the wheels on the front driving wheel frame 2 and the rear driving wheel frame 16 to move along the inner wall of the pipe, making the robot structure move forward or backward. The wheel mounting surface on the wheel frame 16 forms a 15-degree angle with the axis of the front rotating shaft 19 of the motor. When the wheels on the front active wheel frame 2 and the rear active wheel frame 16 move along the inner wall of the pipe, the tilted wheels cause the robot's movement direction to be divided into rotation around the inner side of the pipe and movement along the axis of the pipe, thus enabling the robot to move forward or backward. After the traction ring 1 is removed, the power structure of the motor 14 can be connected through the front support shaft 3 and the rear support shaft 17 of the motor, so that the power structure of the robot is connected into a power joint with stronger power transmission to meet the usage requirements.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
