Description

Technical Field

[0001] The utility model relates to the technical field of pipe flanging cutting, in particular to a flanging cutting device and a flanging cutting system. Background Art

[0002] Application scenarios for internal flange cutting devices include cable ducts. The cutting device moves autonomously within the duct, seeks the internal flange cutting surface, performs the cutting operation, and exits the duct after the operation is completed. Common cutting devices primarily consist of a body and a cutterhead. To ensure the cutting device can autonomously navigate within the duct, the body is also equipped with a drive mechanism equipped with rollers. When the cutting device is located within the duct, the rollers abut against the inner wall of the duct, and the drive mechanism rotates the rollers to drive the entire cutting device within the duct.

[0003] However, in actual processing, many pipes have different internal dimensions. The drive mechanism on the cutting device in the related art can only smoothly move within pipes of a predetermined size. When encountering a pipe exceeding the predetermined size, the rollers on the drive mechanism cannot fully abut the inner wall of the pipe, affecting the stability and power of the movement. When encountering a pipe that is smaller than the predetermined size, the cutting device cannot enter the pipe. Therefore, there is an urgent need for a cutting device that can adapt to moving inside pipes of different sizes. Utility Model Content

[0029] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

[0030] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] On the one hand, the present invention provides a flanging cutting device for cutting the flanging inside the cable duct. In one embodiment, please refer to Figure 1 and Figure 2 The flanging cutting device includes a main frame 1, a cutting structure 4 and multiple driving structures 3, wherein the main frame 1 is the main body of the entire cutting device. The main frame 1 provides an installation environment for the remaining structures of the cutting device, and also serves as a supporting body for some structures.

[0033] The cutting structure 4 is provided at one end of the main frame 1 . The cutting structure 4 is generally rotatably connected to the main frame 1 . The cutting structure 4 is used for cutting the flanging.

[0034] Multiple drive structures 3 are spaced apart around the outer surface of the main frame 1. One end of each drive structure 3 includes a roller 33, and the other end of each drive structure 3 is rotatably connected to the main frame 1. Driven by a drive element within the drive structure 3, the roller 33 is capable of rolling. When the drive structure 3 rotates until the roller 33 abuts the inner wall of the pipe, the roller 33 rotates, driving the entire cutting device to move. It will be appreciated that to ensure that the roller 33 can drive the flanging cutting device along the extended path of the pipe, the rotating axis of the roller 33 is preferably perpendicular to the extended path of the pipe.

[0035] An adjustment structure 2 is disposed between the main frame 1 and the drive structure 3. The adjustment structure 2 includes an adjustment member 23 capable of rotating relative to the main frame 1 and a positioning member 21 disposed on the drive structure 3. The rotation axis of the adjustment member 23 is parallel to and spaced apart from the rotation axis of the drive structure 3. The adjustment member 23 is configured to connect to a preset connection position of the positioning member 21 during rotation. It is worth noting that the positioning member 21 has multiple preset connection positions, which are arranged on the drive structure 3 in a direction perpendicular to the rotation axis of the drive structure 3. It is conceivable that when the ends of the adjustment member 23 are connected to different preset connection positions, the drive structure 3 can be driven to rotate by a predetermined angle relative to the main frame 1.

[0036] By rotating the drive structure 3 and providing the adjustment structure 2, and utilizing the coordination between the adjustment member 23 and the positioning member 21, the adjustment member 23 can be connected to different preset connection positions on the positioning member 21. This forces the drive structure 3 to rotate, and the rotation angle of the drive structure 3 varies with the different connection positions of the adjustment member 23 on the positioning member 21. This allows the angle between the drive structure 3 and the main frame 1 to be adjusted, that is, the expansion angle of the multiple drive structures 3 on the main frame 1 to be adjusted to accommodate pipes of different inner diameters, allowing the flanging cutting device to operate smoothly within pipes of varying inner diameters.

[0037] In one embodiment, see Figure 1 and Figure 2 The adjustment structure 2 further includes a support member 22, one end of which is fixedly connected to the main frame 1, and the end of the support member 22 away from the main frame 1 is rotatably connected to the adjustment member 23. The support member 22 is used to provide a connection structure for the adjustment member 23, so that the adjustment member 23 is rotatably connected to the main frame 1.

[0038] It should be noted that, in a specific embodiment, please combine Figure 3 The structure of the adjusting member 23 is not limited, and it is mainly connected to the positioning member 21. In a specific case of this embodiment, the adjusting member 23 includes two connecting rods 231 and an abutting rod 232 arranged between the two connecting rods 231, wherein the two connecting rods 231 are arranged in a completely identical manner, one end of the two connecting rods 231 is respectively connected to the two ends of the abutting rod 232, and the other ends of the two connecting rods 231 are respectively rotatably connected to the support member 22.

[0039] Specifically, the two connecting rods 231 are arranged parallel to each other and located on the same side. The ends of the connecting rods 231 away from the abutment rod 232 are bent, and the bent portion is rotatably connected to the support member 22. The end of the support member 22 away from the main frame 1 is provided with a rotation bearing, and the end of the connecting rod 231 can be connected to the bearing to be rotatably connected to the support member 22.

[0040] It is worth mentioning that the support member 22 can be an integrally formed structure. In a preferred embodiment, please combine it with Figure 4 The support member 22 is not an integrally formed structure, and the support member 22 can be configured as a telescopic structure. Specifically, the support member 22 includes a fixed portion 222 fixedly connected to the main frame 1 at one end, a sleeve portion 221 threadedly connected to the fixed portion 222, and an adapter portion 223 rotatably connected to the sleeve portion 221. The adapter portion 223 is connected to the end of the sleeve portion 221 away from the fixed portion 222, and the adjustment member 23 is rotatably connected to the adapter portion 223. The advantage of this arrangement is that the length of the entire support member 22 can be changed by rotating the sleeve portion 221 and utilizing the threaded connection between the sleeve portion 221 and the fixed portion 222, that is, the support member 22 can be extended or retracted. This telescopic movement of the support member 22 can have a secondary drive effect. The connection between the adjustment member 23 and the positioning member 21 is equivalent to a primary drive, driving the drive structure 3 to rotate to a predetermined angle. In order to avoid interference from errors, the secondary drive effect of the support member 22 can drive the drive structure 3 to perform fine adjustments to ensure that the roller 33 can abut against the inner wall of the pipe.

[0041] In another preferred embodiment, the support member 22 can also be a cylinder or a hydraulic cylinder, one end of the cylinder or hydraulic cylinder is fixed on the main frame 1, and the output end is rotatably connected to the adjustment member 23, which can also achieve a fine-tuning effect.

[0042] In one embodiment, the positioning member 21 is specifically a plurality of positioning hooks spaced apart on the drive structure 3, with equal spacing between the positioning hooks. The positioning hooks are arranged perpendicular to the rotation axis of the drive structure 3, are curved, and have one end fixedly connected to the drive structure 3, with a gap between the other end and the drive structure 3. The positioning hooks are preferably made of an elastic material, such as elastic plastic or silicone. A gap is defined between the positioning hook body and the drive structure 3, and the end of the adjusting member 23 can pass through the gap between the end of the positioning hook and the drive structure 3 and enter the gap between the positioning hook and the drive structure 3, thereby securing the end of the adjusting member 23 to the drive structure 3.

[0043] It should be noted that the gap between the end of the positioning hook and the drive structure 3 is smaller than the size of the end of the adjusting member 23. The elastic effect of the positioning hook can expand this gap to allow the end of the adjusting member 23 to pass smoothly. As can be seen from the above, one structure of the adjusting member 23 includes a connecting rod 231 and an abutting rod 232. By rotating the connecting rod 231, the abutting rod 232 can be buckled between the positioning hook and the drive structure 3.

[0044] In addition, please refer to Figure 1The dotted line in the figure represents the rotation axis of the cutting mechanism 4. The main frame 1 is cylindrical and coaxial with the rotation axis of the cutting mechanism 4. The driving mechanism 3 is evenly distributed on the outer surface of the main frame 1 around the rotation axis of the cutting mechanism 4. The rotation axis of the driving mechanism 3 and the rotation axis of the adjusting member 23 are both perpendicular to the rotation axis of the cutting mechanism 4.

[0045] In order to ensure the operating effect, multiple pairs of drive structures 3 are set on the main frame 1, and the multiple pairs of drive structures 3 are arranged around the outer wall of the main frame 1. Each pair of drive structures 3 includes two drive structures 3 arranged at intervals, and the two drive structures 3 are arranged along the rotating axis of the cutting structure 4.

[0046] In one embodiment, the drive structure 3 includes an outer frame 31, a drive motor 32 disposed in the outer frame 31, and a transmission member 34 connected to the output end of the drive motor 32. One end of the outer frame 31 is rotatably connected to the main frame 1 via a connector 11, and the other end of the outer frame 31 is rotatably connected to a roller 33. The output end of the transmission member 34 is connected to the roller 33, and the input end of the transmission member 34 is connected to the output end of the drive motor 32. The transmission member 34 is preferably a differential, which can transmit the motion output by the drive motor 32 to the roller 33 through the differential to drive the roller 33 to rotate.

[0047] In a preferred embodiment, the connecting member 11 can be a lifting cylinder or a hydraulic cylinder, one end of which is fixedly connected to the main frame 1, and the output end of the connecting member 11 is rotatably connected to the outer frame 31. The connecting member 11 is set as a cylinder or a hydraulic cylinder, and its function is the same as the telescopic function between the supports mentioned above, which is to provide a secondary adjustment of the angle of the outer frame 31.

[0048] In one embodiment, the cutting structure 4 includes a rotary motor 41 disposed in the main frame 1, a cutter disc 42 connected to the protruding end of the rotary motor 41, and a cutter 43 disposed on the cutter disc 42. The rotary motor 41 can drive the cutter disc 42 to rotate, thereby driving the cutter 43 to cut the flange.

[0049] It should be noted that infrared sensors 50 are installed on the end of the cutter head 42 facing away from the main frame 1 and on part of the drive mechanism. The infrared sensors 50 can sense the position and distance of the flanging. Furthermore, the present invention provides a flanging cutting system comprising a control module and the flanging cutting device described above. The control module can be electrically connected to the drive motor and the rotary motor to control the rotation of the drive motor and the rotary motor.

[0050] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
