Description

Technical Field

[0001] The invention relates to the technical field of pipeline cutting, in particular to a pipeline cutting device for highway bridge construction. Background Art

[0002] When setting up a drainage pipe system on the deck or bottom of a highway bridge, the pipe needs to have a certain slope to ensure smooth drainage. If multiple drainage pipes are installed in parallel and in the same drainage area, cutting the pipes of the same length can ensure that their slopes are the same. For example, if drainage pipes are set up on the inside of the bridge's crash barrier, multiple pipes are arranged longitudinally along the bridge, cutting the same length and combining a uniform installation height can ensure a consistent drainage slope and prevent the occurrence of water accumulation. Water accumulation will erode the bridge structure and may affect the durability of the structure in the long run.

[0003] To meet the above requirements, if multiple pipes can be cut at the same time, it can save a lot of time compared to cutting a single pipe. For this reason, operators have bundled multiple pipes together and cut them at the same time, but the cutting results show that the bundled pipes will deform when cut due to the squeezing and restraint of the surrounding pipes. Especially for some thin-walled pipes, under the dual effects of bundling pressure and cutting force, local dents or twists are likely to occur. This deformation may cause the inner diameter of the pipe to change, affecting the smooth flow of water, and it will also increase the difficulty of connection during the subsequent installation process, because the deformed pipe may not fit tightly with other pipe fittings or pipes.

[0004] To this end, we propose a device that can cut multiple pipes. Summary of the invention

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1, reference Figures 1 to 5 , which is the first embodiment of the present invention.

[0027] Specifically, the bearing assembly 100 includes a bracket 101, wherein the bracket 101 supports the entire device. The pipe fixing assembly 200 includes a rotating frame 201 and a plurality of mounting channels 201a arranged in a circumferential array on the outer wall of the rotating frame 201; wherein, in this embodiment, a total of six mounting channels 201a are provided on the rotating frame 201, and a pipe P to be cut can be placed in each mounting channel 201a.

[0028] The pipes P are detachably connected to each installation channel 201a; wherein the pipes P are fixed in the installation channel 201a waiting to be cut, and the cut pipes P will also serve as one of the necessary conditions for the rotating rack 201 to be able to rotate.

[0029] The transmission assembly 300 includes a transmission plate 301 and a cutter 302 disposed on the transmission plate 301 for cutting the pipe P. When the transmission plate 301 is controlled to move, the cutter 302 moves synchronously with the transmission plate 301, and each pipe P on the installation channel 201a can be cut one by one.

[0030] Example 2, reference Figures 1 to 5 , which is the second embodiment of the present invention.

[0031] Specifically, the end surface of the bracket 101 is screwed with the split plate 102, and the first rotating shaft 102a and the second rotating shaft 102b for supporting the rotating frame 201 to rotate are respectively arranged on both sides of the end surface of the split plate 102, wherein the second rotating shaft 102b and the rotating frame 201 are located in the same axial direction. It should be noted that the second rotating shaft 102b does not provide power for the rotating frame 201 to rotate, but only supports the rotation of the rotating frame 201 when it rotates. In addition, the first rotating shaft 102a and the second rotating shaft 102b are not in the same axial direction, the second rotating shaft 102b is the axis of the rotating frame 201, and the first rotating shaft 102a is arranged directly above the second rotating shaft 102b.

[0032] The end surface of the first rotating shaft 102a is provided with an eccentric plate 103, and the transmission assembly 300 further includes a transmission shaft 301a provided on the transmission plate 301, and the transmission shaft 301a is connected to one side of the end surface of the eccentric plate 103. The first rotating shaft 102a will serve as a power output shaft to drive the eccentric plate 103 to rotate, thereby causing the transmission plate 301 to move synchronously.

[0033] The outer wall of the transmission plate 301 is provided with a transmission groove 301b, and the cutting machine 302 is arranged in the transmission groove 301b. The outer wall of the transmission plate 301 is also provided with a limit groove 301c, and the limit groove 301c is sleeved on the outer wall of the second rotating shaft 102b. In the process of the transmission plate 301 moving with the eccentric plate 103, it will be subject to certain restrictions, that is, the second rotating shaft 102b will always be sleeved in the limit groove 301c, thereby realizing the movement restriction of the transmission plate 301 and ensuring that the movement stroke of the transmission plate 301 does not deviate.

[0034] The inner wall of the transmission groove 301b is movably connected to the outer wall of the pipe P. When the transmission groove 301b is inserted along the pipe P, the cutter 302 will cut the excess part of the pipe P, and the remaining part will serve as one of the necessary conditions for the rotating frame 201 to rotate.

[0035] That is, when the pipe P is inserted into the transmission plate 301, the portion to be cut needs to protrude from the transmission plate 301, and after the pipe P is cut, the pipe P still protrudes from the transmission plate 301. In this embodiment, the pipe P needs to protrude from the rotating frame 201 by at least two centimeters, otherwise the rotating frame 201 will not be able to rotate.

[0036] In summary, before cutting the pipes P, each pipe P is first inserted into the installation channel 201a for fixing. After each pipe P is fixed, the first rotating shaft 102a is controlled to rotate, and the first rotating shaft 102a drives the transmission plate 301 to rotate through the eccentric plate 103. The rotation of the transmission plate 301 is limited by the second rotating shaft 102b being sleeved in the limiting groove 301c.

[0037] like Figure 3 As described above, the restricted transmission plate 301 will be inserted outside the pipe P on the upper left. During this process, the cutter 302 will cut part of the pipe P. Then, the transmission plate 301 will shrink and push the rotating frame 201 through the cooperation between the transmission slot 301b and the cut pipe P, so that the rotating frame 201 rotates clockwise. Each rotation angle of the rotating frame 201 is 60°. At this time, the pipe P originally located on the horizontal left side will rotate to the upper left and will be cut again by the cutter 302 on the transmission plate 301. In this way, the cutting work of all pipes P is completed.

[0038] It should be noted that, since the pipe P needs to protrude from the rotating frame 201 by at least two centimeters to ensure that the rotating frame 201 can rotate, the part that exceeds the rotating frame 201 by two centimeters will be cut.

[0039] Example 3, reference Figures 1 to 5 , which is the third embodiment of the present invention.

[0040] Specifically, a fastening block 202 for fixing the pipe P is slidably disposed on the inner wall of the installation channel 201a, and a connecting rod 202a is disposed on the end surface of the fastening block 202. The fastening block 202 is slidably connected to the inner wall of the installation channel 201a, and no deviation occurs.

[0041] A screw rod 201c is fixedly provided on the end surface of the rotating frame 201, and a connecting plate 203 is sleeved on the outer wall of the screw rod 201c. A connecting groove 203a movably connected to the connecting rod 202a is formed through the outer wall of the connecting plate 203.

[0042] The outer wall of the screw rod 201c is detachably provided with a nut 201c-1 for fixing the connection disk 203. The connection disk 203 can be fixed by the threaded fit between the nut 201c-1 and the screw rod 201c so that it cannot rotate.

[0043] The outer wall of the rotating frame 201 is provided with scale lines 201b for measuring the length of the pipeline P. The scale lines 201b can facilitate the staff to measure the length of the pipeline P.

[0044] The bearing assembly 100 further includes a motor 104, and an output end of the motor 104 is connected to the first rotating shaft 102a. The motor 104 serves as a power source for the first rotating shaft 102a to rotate.

[0045] In summary, before cutting the pipes P, each pipe P needs to be fixed in the installation channel 201a. The pipes P are fixed by controlling the displacement of the fastening block 202 and clamping the pipes P through the inner wall of the installation channel 201a. To further optimize the fixing effect, the fastening block 202 is arc-shaped on the side close to the pipe P and is made of rubber material.

[0046] When each pipe P is located in the installation channel 201a, the connecting disk 203 can be controlled to rotate. During the rotation process, the connecting disk 203 will move away from each other through the active cooperation of the connecting groove 203a and the connecting rod 202a until the fastening block 202 contacts the pipe P, thereby completing the fixing of the pipe P. When the pipe P is fixed, the connecting disk 203 can be restricted from rotating by rotating the nut 201c-1, thereby ensuring the fixing stability of the pipe P.
