Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, and in particular to a tracked motion mechanism and pipeline inspection equipment. Background Technology

[0002] Currently, pipeline inspection equipment typically requires a tracked motion mechanism for movement. To reduce the size of the equipment, it usually employs a structure where the inspection device is mounted on an independently moving tracked motion mechanism. However, the currently available independently moving tracked motion mechanism has poor adaptability to the pipeline environment and has difficulty moving when encountering obstacles, thus reducing work efficiency. Utility Model Content

[0003] The main purpose of this utility model is to propose a tracked motion mechanism, which aims to solve the problem that the existing tracked motion mechanisms have poor adaptability to their own environment, have difficulty moving when encountering obstacles, and thus reduce work efficiency.

[0004] To solve the above problems, this utility model proposes a tracked motion mechanism, comprising:

[0005] A connecting assembly, comprising two connected drive arms, each drive arm having a first drive component inside. Each first drive component includes a first drive member and a first transmission member, one end of the first transmission member being connected to the drive shaft of the first drive member; and

[0006] A motion assembly, comprising two track assemblies, one track assembly connected to the other end of a first transmission member, the first transmission member driving one end of the track assembly to swing relative to the inner wall of the pipe, thereby lifting the other end of the track assembly to overcome an obstacle; and

[0007] Two second drive components are provided, one of which is disposed within one of the track components to drive the track component to move.

[0008] In one embodiment, the track motion mechanism includes a detection component and a controller, both of which are located within the drive arm. The detection component is electrically connected to the controller and is used to detect the swing angle of the track component in real time and transmit it to the controller.

[0009] In one embodiment, the detection assembly includes a rotating component, a magnet, and a detection component. The rotating component is tractively connected to the first transmission component. The rotating component and the detection component are arranged facing each other. The magnet is installed on the end of the rotating component facing the detection component.

[0010] The rotating component can rotate synchronously with the first transmission component so that it rotates relative to the detection component.

[0011] In one embodiment, the tracked motion mechanism includes two detection components, one of which is disposed within one of the drive arms.

[0012] In one embodiment, the track assembly includes an outer track, two baffles, a drive wheel, and a driven wheel. The drive wheel and the driven wheel are spaced apart. The outer track is wrapped around the outer periphery of the drive wheel and the driven wheel. The two baffles are respectively installed on both sides of the drive wheel and the driven wheel. The second drive assembly is installed on one end of one of the baffles and is driven and connected to the drive wheel to drive the outer track to perform circumferential movement. The first transmission member is connected to the other end of one of the baffles.

[0013] In one embodiment, the diameter of the driving wheel is larger than the diameter of the driven wheel.

[0014] In one embodiment, the track assembly includes a tensioning wheel connected between the two baffles and abutting against the inner circumference of the outer track.

[0015] In one embodiment, the tracked motion mechanism includes a control platform, with two drive arms connected to both ends of the control platform. The control platform is equipped with a control component, and the first drive component and the second drive assembly are both electrically connected to the control component.

[0016] In one embodiment, the track movement mechanism includes a connector, one end of which is electrically connected to the control platform, and the other end is used to connect to an external detection device.

[0017] In one embodiment, the pipeline inspection equipment includes a tracked motion mechanism and an inspection body. The tracked motion mechanism is as described above, and the inspection body is installed at one end of the tracked motion mechanism.

[0018] This utility model proposes a tracked motion mechanism. When the tracked motion mechanism is working, a second drive assembly drives the track assembly to move, thereby achieving stable movement of the tracked motion mechanism. When the tracked motion mechanism encounters an obstacle, a first drive assembly is activated. The first drive member of the first drive assembly drives the first transmission member to rotate. The rotation of the first transmission member causes the track assembly connected to it to swing and lift, allowing it to climb up the obstacle on the inner wall of the pipe and gradually overcome the obstacle. After overcoming the obstacle, the first drive member, through the first transmission member, rotates the track assembly to a normal movement angle and continues to move forward. This improves the environmental adaptability of the tracked motion mechanism and increases its working efficiency. Attached Figure Description

[0031] Currently, pipeline inspection equipment typically requires a tracked motion mechanism for movement. To reduce the size of the equipment, it usually employs a structure where the inspection device is mounted on an independently moving tracked motion mechanism. However, the currently available independently moving tracked motion mechanism has poor adaptability to the pipeline environment and has difficulty moving when encountering obstacles, thus reducing work efficiency.

[0032] To address the aforementioned problems, this utility model proposes a tracked motion mechanism, aiming to solve the problem that existing tracked motion mechanisms have poor environmental adaptability, difficulty in moving when encountering obstacles, and reduced work efficiency.

[0033] like Figure 1 , Figure 2 and Figure 4 In one embodiment, the tracked motion mechanism includes a connecting assembly 10, a motion assembly 30, and two second drive assemblies 40. The connecting assembly 10 includes two connected drive arms 11, each of which has a first drive assembly 20 inside. The first drive assembly 20 includes a first drive member 21 and a first transmission member 22. One end of the first transmission member 22 is connected to the drive shaft of the first drive member 21. The motion assembly 30 includes two track assemblies 31. One track assembly 31 is connected to the other end of the first transmission member 22. The first transmission member 22 drives one end of the track assembly 31 to swing relative to the inner wall of the pipe, so that the other end of the track assembly 31 is lifted to overcome obstacles. A second drive assembly 40 is disposed inside one track assembly 31 to drive the track assembly 31 to move.

[0034] In this embodiment, the two drive arms 11 are symmetrically arranged relative to the vertical central axis of the tracked motion mechanism, and the track assembly 31 connected to the two drive arms 11 is also symmetrically arranged. This allows the tracked motion mechanism to quickly switch between forward and backward movement. Simultaneously, the symmetrical arrangement can evenly distribute the load of the tracked motion mechanism, helping to reduce offset or tilting caused by uneven load during movement, thereby improving its motion stability. The first drive member 21 is a drive motor, with a drive shaft extending from one end. The drive shaft is a worm gear, and a worm wheel is correspondingly arranged on the first transmission member 22. The torque of the first drive member 21 is converted into the rotation of the first transmission member 22 through the meshing transmission between the worm wheel and the worm gear. This rotation drives the track assembly 31 connected to the other end of the first transmission member 22 to rotate relative to the inner wall of the pipe. This oscillation allows the other end of the track assembly 31 to rise, thereby achieving obstacle-crossing functionality. The second drive assembly 40 is located inside the track assembly 31 to drive the track assembly 31 to move, ensuring that the track movement mechanism can move stably in the pipe in a non-obstacle-crossing state.

[0035] When the tracked motion mechanism is in operation, the second drive assembly 40 drives the track assembly 31 to move, thereby achieving stable movement of the tracked motion mechanism. When the tracked motion mechanism encounters an obstacle, the first drive assembly 20 is activated. The first drive member 21 of the first drive assembly 20 drives the first transmission member 22 to rotate. The rotation of the first transmission member 22 drives the track assembly 31 connected to it to rotate and lift, allowing it to climb up to the obstacle on the inner wall of the pipe and gradually overcome the obstacle. After overcoming the obstacle, the first drive member 21, through the first transmission member 22, rotates the tracked motion assembly 30 to the normal movement angle and continues to move forward, thereby improving the environmental adaptability of the tracked motion mechanism and increasing its work efficiency.

[0036] like Figure 2 and Figure 3 In one embodiment, the track motion mechanism includes a detection component 50 and a controller (not shown). Both the detection component 50 and the controller are located inside the drive arm 11. The detection component 50 is electrically connected to the controller. The detection component 50 is used to detect the swing angle of the track assembly 31 in real time and transmit it to the controller.

[0037] In this embodiment, the detection component 50 is located inside the drive arm 11 and is used to detect and transmit the rotation angle of the track assembly 31 in real time, which can effectively improve the control accuracy and response speed of the track motion mechanism.

[0038] Specifically, the detection component 50 includes a rotating component 51, a magnet 52, and a detection component 53. The magnet 52 is installed on the end of the rotating component 51 facing the detection component 53. The rotating component can rotate synchronously with the first transmission component 22 so that it rotates relative to the detection component 53.

[0039] The rotating component 51 is a gear, and the first transmission component 22 also has a gear at the corresponding position of the rotating component 51. The meshing of the two gears causes the rotating component 51 to rotate. Simultaneously, a rotating shaft is integrated into the end of the rotating component 51 facing the detection component 53. A magnet 52 is mounted on the end of this shaft facing the detection component 53. The detection component 53 includes a housing and a metal sensing plate. The metal sensing plate is mounted on the housing, and the housing covers the rotating component 51 so that the magnet 52 is directly opposite the metal sensing plate. When the first transmission component 22 rotates, the rotating component 51 rotates synchronously with it. Simultaneously, the magnet 52 rotates relative to the metal sensing plate, generating a transmission signal through eddy currents between them. The metal sensing plate collects and converts this signal, ultimately transmitting it to the controller. After receiving the rotation angle data from the detection component 50, the controller can adjust the rotation angle of the track assembly 31 in real time, thereby ensuring the stability of the track movement mechanism during movement and avoiding obstacle-crossing difficulties due to angular deviations.

[0040] like Figures 1 to 3 In one embodiment, the tracked motion mechanism includes two detection components 50, one of which is disposed within a drive arm 11.

[0041] In this embodiment, both drive arms 11 of the tracked motion mechanism are equipped with detection components 50 to ensure precise control of the rotation of both track components 31. Whether the tracked motion mechanism moves forward or backward, it can quickly overcome obstacles, further improving the obstacle-crossing capability of the tracked motion mechanism.

[0042] like Figure 1 and Figure 4 In one embodiment, the track assembly 31 includes an outer track 311, two baffles 312, a drive wheel 313, and a driven wheel 314. The drive wheel 313 and the driven wheel 314 are spaced apart. The outer track 311 is wrapped around the outer periphery of the drive wheel 313 and the driven wheel 314. The two baffles 312 are respectively installed on both sides of the drive wheel 313 and the driven wheel 314. The second drive assembly 40 is installed on one end of a baffle 312 and is driven and connected to the drive wheel 313 to drive the outer track 311 to move circumferentially. The first transmission member is connected to the other end of a baffle.

[0043] In this embodiment, the outer track 311 is wrapped around the outer periphery of the drive wheel 313 and the driven wheel 314, forming a preliminary motion structure. The distance between the drive wheel 313 and the driven wheel 314 is adjusted according to the actual working conditions to ensure that the drive wheel 313 and the driven wheel 314 can fully tension the outer track 311, thereby ensuring the motion stability of the track assembly 31. Both the drive wheel 313 and the driven wheel 314 are inserted into the two baffles 312 through a connecting rod. At the same time, multiple limiting parts are provided at intervals on the inner periphery of the track. The drive wheel 313 and the driven wheel 314 are clamped in the limiting parts to ensure that they will not deviate relative to the outer track 311 during movement. The second drive assembly 40 is mounted on a baffle 312 and is driven to the drive wheel 313. The second drive assembly 40 can be a drive motor, drive motor or other type of drive device. The second drive assembly 40 transmits power to the drive wheel 313, driving the outer track 311 and the driven wheel 314 to perform stable circumferential movement, thereby ensuring the overall motion stability of the track movement mechanism.

[0044] like Figure 1 and Figure 4 In one embodiment, the diameter of the driving wheel 313 is larger than the diameter of the driven wheel 314.

[0045] In this embodiment, the diameter of the drive wheel 313 is larger than that of the driven wheel 314, which can increase the contact area between the drive wheel 313 and the outer track 311, thereby improving the traction force and reducing the difficulty of lifting the track assembly 31. At the same time, the larger drive wheel 313 can provide better stability, reduce the vibration and deviation of the track assembly 31 during the movement, and ensure the overall movement stability of the track movement mechanism.

[0046] like Figure 1 and Figure 4 In one embodiment, the track assembly 31 includes a tension wheel 315, which is connected between two baffles 312 and abuts against the inner circumferential side of the outer track 311.

[0047] In this embodiment, the tensioning wheel 315 abuts against the inner circumference of the outer track 311 and is connected to the two baffles 312 to ensure its installation stability. The tensioning wheel 315 can keep the outer track 311 with sufficient tension at all times to prevent the outer track 311 from being too loose or too tight, and ensure that the track assembly 31 can operate stably during pipeline inspection, reducing vibration and deviation.

[0048] like Figure 1 and Figure 5 In one embodiment, the tracked motion mechanism includes a control platform 60, two drive arms 11 connected to both ends of the control platform 60, and a control component 61 provided inside the control platform 60. The first drive component 21 and the second drive assembly are both electrically connected to the control component 61.

[0049] In this embodiment, the control platform 60 is located at the center of the tracked motion mechanism. The control platform 60 is a shell structure, with two drive arms 11 symmetrically connected to both ends of the control platform 60 to ensure that the load is evenly distributed between the two drive arms 11, thereby improving the stability and reliability of the entire tracked motion mechanism. The control platform 60 contains a control component 61, which is used to adjust the rotational speed and torque of the first drive component 21 and the second drive component to adapt to different pipeline environments and detection requirements. This also enables the autonomous movement of the tracked motion mechanism, improving its practicality.

[0050] like Figure 1 and Figure 5 In one embodiment, the track movement mechanism includes a connector 70, one end of which is electrically connected to the control platform 60, and the other end is used to connect to an external detection device.

[0051] In this embodiment, the plug-in part 70 is an aviation plug-in connector used to connect with external testing equipment. The design of the plug-in part 70 enables the tracked motion mechanism to cooperate with different testing equipment, thereby allowing different testing equipment to be used for testing in different pipeline environments, thus improving the versatility of the tracked motion mechanism.

[0052] This utility model also proposes a pipeline inspection device (not shown), which includes a tracked motion mechanism and an inspection body. The inspection body is installed at one end of the tracked motion mechanism, which can independently drive the inspection body to perform inspection within the pipeline. The specific structure of the tracked motion mechanism is described in the above embodiments. Since this tracked motion mechanism adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be elaborated further here.

[0053] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
