Description

Technical Field

[0001] This utility model relates to the field of pipeline robots, and in particular to an installation mechanism for a pipeline robot. Background Technology

[0002] As a means of transporting fluid media, pipelines inevitably suffer damage or scale buildup on their inner walls during prolonged use. However, since most pipelines have limited internal space, making it inconvenient for maintenance personnel to enter, specialized pipeline robots are required for pipeline repair.

[0003] Because different pipes have different inner diameters, when a pipe robot is repairing a pipe, a corresponding mounting mechanism needs to be installed on the outside of the pipe to support its stable movement inside the pipe. However, the mounting mechanisms in the existing technology are limited to a single size. For example, in the camera mounting mechanism of a circular pipe inspection robot disclosed in patent number CN201620819748.9, a circular plate is located on the left side of the support plate, and a motor that can drive the circular plate to rotate around its own axis is fixed on the support plate. When encountering different pipes, different sizes of mounting mechanisms need to be replaced, and it is not possible to make convenient and quick adjustments according to the size of the pipe's inner diameter. Therefore, this solution proposes a mounting mechanism for a pipe robot. Utility Model Content

[0004] The present invention proposes an installation mechanism for a pipeline robot, which solves the problem of inconvenient adjustment of the installation mechanism of the pipeline robot in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An installation mechanism for a pipeline robot includes a pipeline robot and a detachable mounting part installed on its head, characterized in that a mounting rod is fixed to the head of the pipeline robot.

[0007] The mounting part includes a hollow mounting ring, three abutment mechanisms fixed on the outer ring of the mounting ring, and a gas distribution mechanism installed on the side of the mounting ring. The mounting ring is an incomplete circular ring and is connected to the mounting rod through a connector.

[0008] The abutting mechanism includes a telescopic air cylinder fixed to the outer ring of the mounting ring and a roller installed at the movable end of the telescopic air cylinder. The air cylinder is connected to the inside of the mounting ring, and the three abutting mechanisms are equidistantly distributed on the outer periphery of the mounting ring.

[0009] The gas distribution mechanism includes a piston cylinder fixed to the side of the mounting ring, a first piston plate disposed inside the piston cylinder, and a transmission assembly installed on the side of the mounting ring for driving the first piston plate to move. The piston cylinder has an annular structure, and the piston cylinder is connected to the inside of the mounting ring through a pipe.

[0010] The above technical solution not only makes it easy to fix the installation part on the pipeline robot, but also makes it easy to adjust the length of the telescopic air cylinder in the installation part according to the size of the pipeline's inner diameter, so that it can be stably supported on the inner wall of the pipeline and ensure the stability of the pipeline robot when it moves.

[0011] As a further improvement to the above solution, the angle of the mounting ring is greater than 180° and less than 240°.

[0012] As a further improvement to the above solution, the connector includes multiple connecting blocks fixed to the side of the mounting ring and fixing bolts threaded onto the connecting blocks, and the mounting rod has fixing holes on its outer periphery for connecting the fixing bolts.

[0013] As a further improvement to the above solution, the telescopic air cylinder includes a fixed cylinder fixed to the outer ring of the mounting ring, a second piston plate installed inside the fixed cylinder, and a movable rod fixed to one side of the second piston plate. The fixed cylinder is in communication with the interior of the mounting ring, one end of the movable rod extends to the outside of the fixed cylinder, and the roller is fixed to the end of the movable rod located outside the fixed cylinder.

[0014] The above technical solution allows for adjusting the extension of the telescopic air cylinder by inflating it into the fixed cylinder, and conversely, adjusting the shortening of the telescopic air cylinder by extracting air from the fixed cylinder.

[0015] As a further improvement to the above solution, the transmission assembly includes a gear ring fixed to one side of the outer wall of the first piston plate and a drive component fixed to one side of the outer wall of the mounting ring. The gear ring is coaxially arranged with the piston cylinder, and one end of the gear ring is fixed to the second piston plate. The other end of the gear ring is located outside the piston cylinder and is fixed with an abutment block. One end of the abutment block abuts against the side of the mounting ring.

[0016] The above technical solution utilizes the rotation of the gear ring to force air from the piston cylinder into the mounting ring, or to draw air from the mounting ring back into the piston cylinder.

[0017] As a further improvement to the above solution, the driving component includes a mounting block fixed to the side of the mounting ring, a rotating shaft rotatably connected to the mounting block, a transmission gear fixed to one end of the rotating shaft, and a rocker arm fixed to the other end of the rotating shaft, wherein the transmission gear meshes with the gear ring.

[0018] The above technical solution allows for convenient and labor-saving rotation of the gear ring.

[0019] As a further improvement to the above solution, a handle is rotatably connected to the side of the rocker arm away from the pivot, and the handle is set perpendicular to the rocker arm.

[0020] As a further improvement to the above solution, a locking bolt is threadedly connected to one side of the mounting block, and one end of the locking bolt abuts against the outer circumference of the rotating shaft.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. With the installation unit, when adjusting pipes of different inner diameters, the length of the telescopic air cylinder is adjusted by drawing air into and releasing air into the installation ring using the air distribution component. The adjustment is complete when the roller abuts against the inner wall of the pipe, which greatly facilitates the adjustment and use by the operator.

[0023] 2. By setting up the air distribution component, the transmission gear can be driven to rotate by rotating the shaft, and the transmission gear will then drive the gear ring to rotate, thereby forcing the air in the piston cylinder into the mounting ring or drawing the air in the mounting ring back into the piston cylinder, thus achieving the purpose of conveniently controlling the extension and retraction of the telescopic air cylinder.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0032] Example 1:

[0033] Please combine Figure 1 - Figure 5 The installation mechanism of a pipeline robot according to this embodiment includes a pipeline robot 11 and a detachable mounting part installed on its head. The pipeline robot 11 has a mounting rod 16 fixed on its head, and the mounting part is installed on the mounting rod 16 and located at the front end of the pipeline robot.

[0034] The mounting section includes a hollow mounting ring 1, three abutment mechanisms fixed to the outer ring of the mounting ring 1, and a gas distribution mechanism installed on the side of the mounting ring 1. The mounting ring 1 is an incomplete circular ring with an angle greater than 180° and less than 240°. The incomplete circular ring design facilitates its assembly and disassembly with the mounting rod 16. The mounting rod 16 can simply pass through the notch on the mounting ring 1. The angle of the mounting ring 1 is greater than 180° so that when one abutment mechanism is located at the center of the mounting ring 1, the other two abutment mechanisms can be installed on one diameter of the mounting ring 1, thus providing more stable support when the abutment mechanism contacts the inner wall of the pipe. The angle of the mounting ring 1 is less than 240° to ensure that the notch on the mounting ring 1 is not too small, thereby facilitating the passage of the mounting rod 16.

[0035] The mounting ring 1 is connected to the mounting rod 16 via a connector. The connector includes multiple connecting blocks 14 fixed to the side of the mounting ring 1 and fixing bolts 15 threaded onto the connecting blocks 14. The mounting rod 16 has fixing holes on its outer periphery for connecting the fixing bolts 15. When fixing, the fixing bolts 15 are screwed into the fixing holes on the mounting rod 16 to fix the mounting part onto the mounting rod 16. Conversely, when disassembling the mounting part, the fixing bolts 15 are simply unscrewed from the fixing holes.

[0036] The abutment mechanism includes a telescopic air cylinder fixed to the outer ring of the mounting ring 1 and a roller 5 installed at the movable end of the telescopic air cylinder. The air cylinder is connected to the interior of the mounting ring 1. The three abutment mechanisms are equidistantly distributed around the outer periphery of the mounting ring 1. The telescopic air cylinder includes a fixed cylinder 3 fixed to the outer ring of the mounting ring 1, a second piston plate installed inside the fixed cylinder 3, and a movable rod 4 fixed to one side of the second piston plate. The fixed cylinder 3 is connected to the interior of the mounting ring 1, and one end of the movable rod 4 extends to the outside of the fixed cylinder 3. The roller 5 is fixed to the end of the movable rod 4 located outside the fixed cylinder 3. When the air inside the mounting ring 1 increases, the excess air enters the three fixed cylinders 3 respectively, causing the second piston plate inside the fixed cylinder 3 to move outward, and the movable rod 4 to extend outward, making the telescopic air cylinder longer, thus adapting to pipes with larger diameters. Conversely, when the air inside the mounting ring 1 is evacuated, the air in the fixed cylinder 3 flows back into the mounting ring 1, and the movable rod 4 moves inward into the fixed cylinder 3. The length of the telescopic air cylinder becomes shorter, adapting to pipes with smaller diameters.

[0037] The valve train includes a piston cylinder 2 fixed to the side of the mounting ring 1, a first piston plate disposed inside the piston cylinder 2, and a transmission assembly mounted on the side of the mounting ring 1 for driving the first piston plate to move. The piston cylinder 2 has an annular structure and is coaxially arranged with the mounting ring 1, and the piston cylinder 2 is connected to the interior of the mounting ring 1 through a pipe. The transmission assembly includes a toothed ring 9 fixed to the outer wall of one side of the first piston plate and a driving component fixed to the outer wall of one side of the mounting ring 1. The toothed ring 9 is coaxially arranged with the piston cylinder 2, and one end of the toothed ring 9 is fixedly connected to the second piston plate, while the other end of the toothed ring 9 is located outside the piston cylinder 2. A fixed abutment block 10 is provided, with one end of the abutment block 10 abutting against the side of the mounting ring 1. The toothed ring 9 rotates around the axis of the mounting ring 1. When the inner diameter of the pipe is large, driving the toothed ring 9 to move into the piston cylinder 2 can force the air in the piston cylinder 2 into the mounting ring 1, thereby increasing the amount of air in the mounting ring 1 and lengthening the telescopic air cylinder. Conversely, when the inner diameter of the pipe is small, driving the toothed ring 9 to move outward from the piston cylinder 2 can draw the air in the mounting ring 1 back into the piston cylinder 2, thereby shortening the telescopic air cylinder. Thus, by rotating the toothed ring 9, the length of the telescopic air cylinder can be easily adjusted.

[0038] The driving component includes a mounting block 8 fixed to the side of the mounting ring 1, a rotating shaft 17 rotatably connected to the mounting block 8, a transmission gear 13 fixed to one end of the rotating shaft 17, and a rocker arm 7 fixed to the other end of the rotating shaft 17. The transmission gear 13 meshes with the gear ring 9. The length of the rocker arm 7 is greater than the diameter of the transmission gear 13. When driving the gear ring 9 to rotate, the rocker arm 7 is rotated to drive the rotating shaft 17 to rotate. The rotating shaft 17 then drives the transmission gear 13 to rotate, and the transmission gear 13 then drives the gear ring 9 to rotate, thereby achieving the purpose of driving the gear ring 9 to rotate with less effort.

[0039] One side of the mounting block 8 is threaded with a locking bolt 12. One end of the locking bolt 12 abuts against the outer circumference of the rotating shaft 17. After the length of the telescopic air cylinder is adjusted, the locking bolt 12 can be tightened to prevent the toothed ring 9 from loosening. The static friction between the locking bolt 12 and the rotating shaft 17 will lock the rotating shaft 17 and prevent it from loosening. Conversely, when it is necessary to rotate the rotating shaft 17 again, the locking bolt 12 can be loosened, the locking bolt 12 will disengage from the rotating shaft 17, and the rotating shaft 17 can rotate normally.

[0040] Example 2:

[0041] Combination Figure 1 - Figure 5 Based on Embodiment 1, this embodiment is further improved in that: a handle 6 is rotatably connected to the side of the rocker arm 7 away from the rotating shaft 17. The handle 6 is set perpendicular to the rocker arm 7. When rotating the rocker arm 7, holding the handle 6 can easily and conveniently drive the rocker arm 7 to rotate without rubbing against the palm.

[0042] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
