Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary pipeline robot technology, specifically a novel rotary pipeline robot active wheel structure. Background Technology
[0002] Most existing autonomous pipeline robots use motors to rotate wheels, which in turn propel the robot forward. The robot moves inside the pipeline, allowing it to perform construction work at different locations within the pipe.
[0003] Existing motor-driven drive wheels have complex structures and are difficult to place in narrow pipe spaces. In addition, existing shock-absorbing structures are bulky and unsuitable for small-diameter pipes, and their numerous components make them prone to damage. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a novel rotary pipe robot active wheel structure. Through the setting of an active wheel frame, a buffer arm, a main shaft, a wheel mounting frame, an active wheel, a threaded shaft, and a threaded hole, the motor drives the active wheel frame to rotate through the main shaft. When the active wheel frame rotates, the active wheel rotates around the main shaft. The buffer arm deforms and contracts under the pressure of the narrow pipe, thereby allowing the active wheel to move along the inside of the pipe, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel rotary pipeline robot active wheel structure, comprising an active wheel frame, a main shaft mounting hole at the center of the active wheel frame, a main shaft installed in the main shaft mounting hole, three buffer arms on the outer ring side of the active wheel frame, a wheel mounting bracket at one end of each buffer arm, a boss on the wheel mounting bracket, a threaded hole at the center of the boss, a threaded shaft installed in the threaded hole, a rubber-coated bearing sleeved on the threaded shaft, and an active wheel sleeved on the outer side of the rubber-coated bearing, the rubber-coated bearing and the active wheel forming an active wheel structure.
[0006] Furthermore, three set screws are installed on the outer ring side of the main shaft mounting hole, and set screw fixing holes are provided on the drive wheel frame corresponding to the installation positions of the set screws.
[0007] Furthermore, the angle between the mounting surface of the drive wheel and the mounting surface of the main shaft is in the range of 10-80 degrees, and the main shaft is connected to the main shaft mounting hole through the set screw.
[0008] Furthermore, the set screw is threadedly connected to the set screw fixing hole, and the set screw is pressed and fixedly connected to the spindle.
[0009] Furthermore, the threaded shaft and the boss are connected through the threaded hole, and the threaded shaft and the threaded hole are connected by a thread.
[0010] Furthermore, the rubber-coated bearing is interference-fitted with the threaded shaft, and the wheel mounting bracket and the buffer arm are an integral structure.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model, through the setting of an active wheel frame, a buffer arm, a main shaft, a wheel mounting frame, an active wheel, a threaded shaft, and a threaded hole, enables the motor to drive the active wheel frame to rotate through the main shaft. When the active wheel frame rotates, the active wheel rotates around the main shaft. The buffer arm deforms and contracts under the pressure of the narrow pipe, thereby allowing the active wheel to move along the inside of the pipe.
[0013] 2. This utility model uses a buffer arm, a drive wheel, a threaded shaft, and a threaded hole to provide shock absorption between the drive wheel and the main shaft through a bent and deformed buffer arm. The shock absorption structure is simple and not easily damaged. When moving inside a small-diameter pipe, the buffer arm can be squeezed and bent to allow the drive wheel structure to move inside the small-diameter pipe, thus meeting the usage requirements.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0022] Please see Figure 1-6 A novel rotary pipeline robot active wheel structure includes an active wheel frame 1, a main shaft mounting hole 7 at the center of the active wheel frame 1, a main shaft 4 installed in the main shaft mounting hole 7, three buffer arms 6 on the outer ring side of the active wheel frame 1, a wheel mounting bracket 8 at one end of the buffer arm 6, a boss 11 on the wheel mounting bracket 8, a threaded hole 10 at the center of the boss 11, a threaded shaft 5 installed in the threaded hole 10, a rubber-coated bearing 9 sleeved on the threaded shaft 5, and an active wheel 3 sleeved on the outside of the rubber-coated bearing 9. The rubber-coated bearing 9 and the active wheel 3 form the active wheel structure.
[0023] like Figure 1-6 As shown, the drive wheel 3 is connected and fixed to the threaded hole 10 on the wheel mounting bracket 8 via the threaded shaft 5. The angle between the mounting surface of the drive wheel 3 and the wheel mounting bracket 8 and the mounting surface of the main shaft 4 is between 10 and 80 degrees. This allows the buffer arm 6 to rotate when the main shaft 4 drives the drive wheel bracket 1 to rotate. The drive wheel 3 at the end of the buffer arm 6 can be pressed tightly against the inner side of the pipe under the action of the buffer arm 6. The drive wheel 3 and the mounting surface of the wheel mounting bracket 8 form a 15-degree angle. When the drive wheel 3 rotates along the inner side of the pipe, the angle allows the rotational power of the drive wheel 3 to be divided into the power to move along the inner side of the pipe and the power to move along the central axis of the pipe. This allows the robot to rotate and move forward inside the pipe. When the buffer arm 6 encounters a smaller pipe, the buffer arm 6 can be squeezed, bent, and deformed, allowing the drive wheel 3 structure to move in pipes with smaller diameters. The buffer arm 6 is made of elastic buffer material. Preferably, the buffer arm 6 is made of a tortuous thin-walled structure to further increase the range of compression and rebound. At the same time, the shock absorption structure of this utility model is simple and not easily damaged.
[0024] Three set screws 2 are installed on the outer ring side of the spindle mounting hole 7, and set screw fixing holes 12 are provided on the drive wheel frame 1 corresponding to the installation positions of the set screws 2.
[0025] The angle between the mounting surface of the drive wheel 3 and the mounting surface of the spindle 4 is 10-80 degrees. The spindle 4 is connected to the spindle mounting hole 7 by the set screw 2.
[0026] The set screw 2 is connected to the set screw fixing hole 12 by a thread, and the set screw 2 is pressed and fixedly connected to the spindle 4.
[0027] The threaded shaft 5 is connected to the boss 11 through the threaded hole 10, and the threaded shaft 5 and the threaded hole 10 are connected by threads.
[0028] The rubber-coated bearing 9 is interference-fitted with the threaded shaft 5, and the wheel mounting bracket 8 and the buffer arm 6 are an integral structure.
[0029] The working principle of the novel rotary pipeline robot's active wheel structure provided by this utility model is as follows: Figures 1-6 As shown, the drive wheel 3 is connected and fixed to the threaded hole 10 on the wheel mounting bracket 8 via the threaded shaft 5. The angle between the mounting surface of the drive wheel 3 and the wheel mounting bracket 8 and the mounting surface of the main shaft 4 is between 10 and 80 degrees. This allows the buffer arm 6 to rotate when the main shaft 4 drives the drive wheel bracket 1 to rotate. The drive wheel 3 at the end of the buffer arm 6 can be pressed tightly against the inner side of the pipe under the action of the buffer arm 6. The drive wheel 3 forms a 15-degree angle with the mounting surface of the wheel mounting bracket 8. When the drive wheel 3 rotates along the inner side of the pipe, the rotational power of the drive wheel 3 can be divided into the power to move along the inner side of the pipe and the power to move along the central axis of the pipe. This allows the robot to rotate and move forward inside the pipe. When the buffer arm 6 encounters a smaller pipe, the buffer arm 6 can be squeezed, bent and deformed, allowing the drive wheel 3 structure to move in pipes with smaller diameters. At the same time, the shock absorption structure of this utility model is simple and not easily damaged.
