Description

Technical Field

[0001] This application relates to the field of pipe cutting technology, and in particular to a pipe cutting tool for a heating station. Background Technology

[0002] Currently, heating networks, also known as heating pipelines, are heating pipelines that start from boiler rooms, direct-fired machine rooms, heating centers, etc., and run from heat sources to the heating inlets of buildings.

[0003] According to relevant documents, pipe cutting fixtures are equipment used to cut heating pipes. Currently, at some construction sites for heating pipes, when it is necessary to cut the heating pipes, large machinery cannot be used due to space limitations. In general, manual cutting is used, that is, workers first draw lines on the outer surface of the area to be cut on the heating pipe, and then use a handheld cutting machine to cut the heating pipe.

[0004] The existing technical solutions mentioned above have the following drawbacks: When cutting heat pipes manually with a cutting machine, the cutting edge is prone to deviation due to the trembling of the operator's arm, which will ultimately affect the subsequent use of the heat pipe. Summary of the Invention

[0005] This application provides a pipe cutting tool for heating stations to improve the cutting effect of heating pipes and enable them to be used normally afterward.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A pipe cutting fixture for a heating station includes a guide rail that can be installed circumferentially on the pipe to be cut, an mounting plate on the guide rail, a cutting device for cutting the pipe on the mounting plate, and a drive assembly for moving the cutting device along the guide rail on the pipe.

[0008] By adopting the above solution, when it is necessary to cut the heating pipe, the guide rail is installed along the circumference of the heating pipe, ensuring that the guide rail and the heating pipe remain coaxial. After aligning the cutting device with the cutting line on the pipe, the drive assembly will move the cutting device along the guide rail. During the movement of the cutting device, it will cut the pipe. This eliminates the need for manual cutting and prevents the cutting position from deviating due to operator arm tremors, thus improving the cutting effect of the heating pipe and ensuring its normal subsequent use.

[0009] Preferably, the guide rail includes a bendable guide rod, and the guide rod is provided with a connector that mates the two ends of the guide rod together.

[0010] Preferably, the drive assembly includes two drive plates disposed on the side of the mounting plate near the guide rod, the two drive plates being located on both sides of the guide rod, each drive plate being provided with a drive wheel, the central axis of the drive wheel extending along the radial direction of the pipe to be cut, the drive wheel being rotatably connected to the drive plate, and a drive motor being disposed on the mounting plate to drive the drive wheel to rotate on the drive plate.

[0011] Preferably, multiple drive blocks are evenly distributed on the circumference of the drive wheel, and the guide rod has a meshing hole on the side near the drive wheel for inserting the drive blocks.

[0012] Preferably, the guide rod includes two identical branch rods, and the mounting plate is provided with an adjustment component that can drive the two drive plates to move closer to or further away from each other.

[0013] Preferably, the adjustment assembly includes an insertion block disposed on the side of the drive plate near the mounting plate, a bidirectional screw is disposed inside the mounting plate, the bidirectional screw is rotatably connected to the mounting plate, the bidirectional screw passes through two insertion blocks and is threadedly connected to the insertion blocks, and a clearance groove is provided on the mounting plate for the two insertion blocks to move toward each other or away from each other.

[0014] Preferably, the cutting device includes a cutting plate disposed on the side of the mounting plate away from the guide rod and rotatably connected to the mounting plate. A cutting motor is disposed on the cutting plate, and a cutting blade is disposed on the cutting motor. When the cutting plate and the mounting plate are parallel to each other, the cutting blade can cut the pipe.

[0015] Preferably, the mounting plate is provided with two L-shaped locking rods. The two locking rods are located on both sides of the cutting plate and are positioned on the side of the cutting plate away from the rotation axis between the cutting plate and the mounting plate. One end of the locking rod is rotatably connected to the mounting plate, and the other end can press the cutting plate firmly onto the mounting plate.

[0016] Preferably, an auxiliary block is embedded on the upper surface of the mounting plate, the cutting plate is set on the auxiliary block, an adjusting screw is provided inside the mounting plate, the length direction of the adjusting screw is perpendicular to the plane of the guide rod, the adjusting screw is rotatably connected to the mounting plate, the adjusting screw passes through the auxiliary block and is threadedly connected to the auxiliary block, and a through hole is opened at the center of the mounting plate for the cutting blade to pass through.

[0017] Preferably, one end of the guide rod is provided with multiple auxiliary rods, and each auxiliary rod is also provided with a connector, allowing for detachable connections between the auxiliary rods and between the auxiliary rods and the guide rod via the connectors.

[0018] In summary, this application has the following technical effects:

[0019] 1. By setting up a cutting fixture including a guide rail and a drive component, the cutting fixture can replace manual labor to cut pipes, achieving the effects of convenient pipe cutting, saving time and manpower, improving the cutting effect of thermal pipes, and enabling the thermal pipes to be used normally in the future.

[0020] 2. By setting a guide rod that includes two branch rods, when there is a certain distance between the two branch rods, the cutting part is located between the two branch rods, which makes the cutting fixture more convenient to use;

[0021] 3. By setting a drive wheel including a drive block, the drive block on the drive wheel will be inserted into the meshing hole on the side of the guide rod. This makes the drive wheel move more stably on the guide rod and reduces the possibility of the mounting plate falling off the guide rod. Attached Figure Description

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1This application discloses a pipe cutting fixture for a heating station, including a guide rail 2, a mounting plate 3, a cutting device 4, and a drive assembly 5. The guide rail 2 is annular and is fitted onto the outer surface of the pipe 1. The mounting plate 3 is mounted on the guide rail 2. The cutting device 4 and the drive assembly 5 are both mounted on the mounting plate 3. The cutting device 4 is used to cut the pipe 1, and the drive assembly 5 can drive the cutting device 4 to move along the direction of the guide rail 2 on the pipe 1. When the pipe 1 needs to be cut, the cutting device 4 is aligned with the cutting position on the pipe 1. After the cutting device 4 and the drive assembly 5 are started, the cutting device 4 cuts the pipe 1, and the drive assembly 5 drives the cutting device 4 to move along the direction of the guide rail 2 on the pipe 1, thus completing the cutting process of the pipe 1.

[0029] Reference Figure 1 and Figure 2 The guide rail 2 includes a guide rod 21, an auxiliary rod 22, and a connector 23. The guide rod 21 is strip-shaped, and multiple through-holes 211 are evenly provided on its side. Multiple auxiliary rods 22 are provided, and the length of the auxiliary rods 22 is much shorter than that of the guide rods 21. The auxiliary rods 22 are mainly used to fine-tune the total length of the guide rail 2. Auxiliary holes are also provided on the side of the auxiliary rods 22, and the diameter of the auxiliary holes is equal to the diameter of the through-holes 211. The distance between two adjacent auxiliary holes is also equal to the distance between two adjacent through-holes 211. Multiple connectors 23 are also provided. The connectors 23 are provided between the auxiliary rods 22 and the guide rods 21 or between the two ends of the guide rods 21 to connect the two movable ends.

[0030] The connector 23 includes a connecting rod 231 and a plug rod 232. There are two plug rods 232. The two plug rods 232 are respectively located near the two ends of the connecting rod 231 and are fixedly connected to the connecting rod 231. One end face of the plug rod 232 is flush with one side face of the connecting rod 231. The outer diameter of the plug rod 232 is equal to the inner diameter of the auxiliary hole and the meshing hole 211. A plug hole 233 is provided on the end face of the plug rod 232 near the connecting rod 231, which penetrates the connecting rod 231 and extends into the interior of the plug rod 232.

[0031] The guide rail 2 is composed of three parts: guide rod 21, auxiliary rod 22, and connecting rod 231. When the pipe 1 needs to be cut, the number of auxiliary rods 22 to be installed on the guide rod 21 is determined according to the outer diameter of the pipe 1. Then, the auxiliary rods 22 are installed on the guide rod 21 through the connector 23. The auxiliary rods 22 allow people to make fine adjustments to the length of the guide rod 21, making the guide rail 2 more applicable.

[0032] The drive assembly 5 includes a drive plate 51, a drive wheel 52, a drive block 53, and a drive motor 54. Two drive plates 51 are provided, positioned on the same side of the mounting plate 3 and facing each other. Two drive wheels 52 are also provided, each corresponding to one of the two drive plates 51. Each drive plate 51 has a through-hole for mounting, and the drive wheel 52 is located inside the hole and rotatably connected to the drive plate 51. The circumferential surface of the drive wheel 52 abuts against the side of the guide rod 21. The drive block 53 is fixed to the circumferential surface of the drive wheel 52 along its circumference. The outer diameter of the drive block 53 is smaller than the inner diameter of the auxiliary hole or the meshing hole 211, allowing the drive block 53 to be inserted into either the auxiliary hole or the meshing hole 211. The drive motor 54 is located on the end face of the drive plate 51 away from the mounting plate 3. The output shaft of the drive motor 54 extends into the drive plate 51 and is fixedly connected to the drive wheel 52. The drive motor 54 can drive the drive wheel 52 to rotate on the drive plate 51.

[0033] When the drive assembly 5 needs to move the mounting plate 3 on the guide rail 2, the drive motor 54 drives the drive wheel 52 to rotate on the drive plate 51. The drive block 53 on the drive wheel 52 is inserted into the auxiliary holes or meshing holes 211 on both sides of the guide rail 2. Therefore, the drive wheel 52 will drive the drive plate 51 to move on the guide rail 2, so that the cutting device 4 on the mounting plate 3 can cut the pipe 1.

[0034] To make the cutting fixture more convenient to use, the guide rod 21 is configured to include two identical branch rods 212. When using the cutting fixture, the two branch rods 212 can be separated to create a certain distance between them, and then the cutting device 4 can be aligned with the cutting part on the pipe 1 between the two branch rods 212. To make the drive assembly 5 usable, an adjustment assembly 24 is provided on the mounting plate 3 to move the two drive plates 51 closer to or further away from each other.

[0035] Combined Figure 3 and Figure 4The adjustment assembly 24 includes an insertion block 241, a bidirectional screw 242, and an adjustment handle 243. There are two insertion blocks 241, each corresponding to one of the two drive plates 51. The insertion blocks 241 are fixed on the end face of the drive plate 51 near the mounting plate 3 and embedded in the side of the mounting plate 3. The mounting plate 3 has a clearance groove for the two insertion blocks 241 to move closer to or further away from each other. The bidirectional screw 242 is located inside the mounting plate 3 and is rotatably connected to the mounting plate 3. The central axis of the bidirectional screw 242 is perpendicular to the plane of the drive plate 51. The bidirectional screw 242 passes through both insertion blocks 241 and is threadedly connected to them. One end of the bidirectional screw 242 is flush with the side of the mounting plate 3. The adjustment handle 243 is located at one end of the bidirectional screw 242 and can drive the bidirectional screw 242 to rotate.

[0036] After the guide rail 2 is installed on the pipe 1, in order to enable the drive wheel 52 on the drive plate 51 to cooperate with the meshing hole 211 on the guide rod 21, people can adjust the handle 243 to drive the bidirectional screw 242 to rotate. The bidirectional screw 242 is threadedly connected to the insertion block 241. When the bidirectional screw 242 rotates, it will drive the two insertion blocks 241 to move closer to each other or further away from each other. When the insertion blocks 241 move, they will drive the drive plate 51 to move together. In this way, the distance between the two drive plates 51 can be adjusted.

[0037] The cutting device 4 includes a cutting plate 41, a cutting blade 42, a cutting motor 43, a locking rod 44, an auxiliary block 45, and an adjusting screw 46. The auxiliary block 45 is embedded in the side of the mounting plate 3 away from the drive plate 51. The cutting plate 41 is located on the side of the mounting plate 3 away from the drive plate 51, and one end face of the cutting plate 41 is rotatably connected to the upper surface of the auxiliary block 45. The cutting blade 42 is mounted on the cutting plate 41, and the central axis of the cutting blade 42 is in the same direction as the central axis of the pipe 1. The cutting motor 43 is mounted on the cutting plate 41 and can drive the cutting blade 42 to rotate. It should be noted that when the cutting plate 41 rotates on the auxiliary block 45 to be parallel to the mounting plate 3, the vertex of the cutting blade 42 near the pipe 1 will enter the interior of the pipe 1. That is, the cutting blade 42 can... The cutting process of pipe 1 is completed; the locking rod 44 is L-shaped in general, and there are two locking rods 44. The two locking rods 44 are located on both sides of the auxiliary block 45. One end of the locking rod 44 near the auxiliary block 45 is rotatably connected to the auxiliary block 45, and the other end can be rotated to the top of the cutting plate 41 to press the cutting plate 41 onto the auxiliary block 45; the adjusting screw 46 is set inside the mounting plate 3 and is rotatably connected to the mounting plate 3. The central axis direction of the adjusting screw 46 is the same as the central axis direction of the bidirectional screw 242. The adjusting screw 46 passes through the auxiliary block 45 and is threadedly connected to the auxiliary block 45. An adjustment hole is opened on the surface of the mounting plate 3 for the auxiliary block 45 to move back and forth along the central axis direction of the adjusting screw 46. A through hole is opened on the mounting plate 3 for the cutting blade 42 to pass through.

[0038] When the position of the cutting blade 42 on the mounting plate 3 needs to be adjusted, the adjusting screw 46 is driven to rotate on the mounting plate 3. The adjusting screw 46 passes through the auxiliary block 45 and is threadedly connected to the auxiliary block 45. The adjusting screw 46 will drive the auxiliary block 45 to move on the mounting plate 3 until the auxiliary block 45 moves to the predetermined position. After the cutting motor 43 is started, the cutting motor 43 drives the cutting blade 42 to rotate, and then flips the cutting plate 41 on the auxiliary block 45 towards the direction of the pipe 1. When the cutting plate 41 is parallel to the mounting plate 3, the locking rod 44 is used to lock the cutting plate 41 on the auxiliary block 45. Then the drive assembly 5 will drive the cutting plate 41 to move on the guide rail 2 to complete the cutting process of the pipe 1.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
