Description
Technical Field
[0001] This utility model relates to the field of pipeline cutting technology, specifically a pipeline cutting device for water conservancy and hydropower projects. Background Technology
[0002] Water conservancy and hydropower engineering mainly utilizes the basic theories and knowledge of mathematics, mechanics, and building structures necessary for hydropower engineering construction. Through necessary engineering design methods, construction management methods, and scientific research methods, it carries out work in water conservancy and hydropower engineering surveying, planning, design, construction, scientific research, and management. In water conservancy and hydropower engineering, various pipelines often need to be cut to ensure that the pipeline length meets the work requirements, which requires the use of pipeline cutting devices.
[0003] Patent document CN220462392U discloses a pipe cutting device for water conservancy and hydropower engineering. A pipe support unit is mounted on a base, comprising two symmetrically arranged support mechanisms. Each support mechanism includes several support rods, both ends of which are rotatably connected to a positioning frame, which is mounted on the base. Two movable plates are slidably mounted on an adjusting plate, each with two movable seats on its inner side. A rotating cylinder is rotatably mounted between the movable seats. A rotating rod is positioned below the rotating cylinder, with positive and negative threaded sections. Each movable plate is threaded onto these threaded sections. Both ends of the rotating rod are rotatably connected to the positioning plates. A rotating handle is located on the outer side of each positioning plate, rotatably passing through the positioning plate and connecting to the rotating rod. This invention offers advantages such as improved positioning effect, improved cutting quality, enhanced safety, reduced operator workload, simple structure, ease of operation, and durability. However, existing technologies still have shortcomings.
[0004] (1) Existing pipe cutting devices require manual rotation of the threaded rod by the operator to clamp and fix the pipe. However, when the pipe diameter is large, the operator often needs to rotate the threaded rod many times. When cutting the pipe, the operator needs to manually rotate the pipe to be cut 1-2 times. Therefore, the overall operation is cumbersome and cannot automatically fix and rotate the pipe. It is time-consuming and labor-intensive, which increases the labor intensity of the operator. As the working time increases, the operator's physical strength will also decrease at any time, which will have a certain impact on the cutting speed and cutting quality.
[0005] (2) In the prior art, when cutting water conservancy pipelines, a lot of cutting debris is often generated at the cutting end. However, the existing cutting device does not have the function of collecting the debris, which causes the debris to fly around and is difficult to clean, thus affecting the overall cleanliness of the processing workbench.

[0011] An adjustment structure is located at the bottom of the rotating structure;
[0012] The bracket is fixedly connected to the top of the base on the side near the supporting structure;
[0013] A cutting structure, wherein the cutting structure is disposed on the top of the support;
[0014] The debris collection structure is located at the bottom of the base. The debris collection structure includes a collection box fixedly connected to one side of the bottom of the base. A filter screen is fixedly installed on the other side of the collection box. A negative pressure fan is fixedly installed on the other side of the collection box. A dust suction pipe is fixedly connected to the top of the collection box. The dust suction pipe extends to the top of the base and is fixedly connected to a dust suction plate at its end. The dust suction plate is fixedly connected to the front and rear sides of the bottom of the support.
[0015] Furthermore, the support structure includes:
[0016] A support rod, which is fixedly connected to the front and rear ends of one side of the top of the base;

[0019] V-shaped limiting groove, wherein the V-shaped limiting groove is formed on the side opposite to the clamping seat;
[0020] The clamping rollers, a plurality of which are rotatably connected to both sides of the inner wall of the V-shaped limiting groove.
[0021] Furthermore, the adjustment structure includes:
[0022] A groove, wherein the groove is formed on the other side of the top of the base;
[0023] A lead screw is rotatably connected to both sides of the inner wall of the groove;
[0024] Motor 3 is fixedly installed on the other side of the base, and the output end of motor 3 is fixedly connected to the lead screw;
[0025] The slider is threadedly connected to the lead screw and is fixedly connected to the bottom of the mounting plate.

Then, the third motor is started to drive the lead screw to rotate, and the lead screw drives the slider to move left and right, thereby driving the mounting plate to move left and right, so as to facilitate the adjustment of the cutting position. The double-acting cylinder drives the two clamping seats to move towards each other or away from each other at the same time, clamping water pipes of different diameters, making the cutting process more stable. When cutting the pipe, the first motor is started to drive the turntable to rotate, thereby driving the pipe to rotate. After the pipe rotates, the cutting disc can perform a ring cut on the pipe. The pipe can be rotated and cut at the same time, and the pipe can be cut in one go. This avoids the need for manual adjustment of clamping the pipe and manual rotation of the pipe for cutting operations required by the existing technology. The operation is time-saving and labor-saving, and the work efficiency is improved.
[0033] (2) In this utility model, by setting up a debris collection structure, when the pipe is cut, the negative air compressor is started. When the negative air compressor is started, it will continuously output the air inside the collection box to the outside. At this time, there will be a certain negative pressure inside the collection box, so that the suction pipe can transfer the negative pressure inside the collection box to the suction plate. During the cutting process, the debris at the pipe cutting end will also fall into the suction plate due to gravity and the negative pressure below, and be transferred to the collection box by the suction pipe below, thereby reducing the pipe debris residue on the base surface, making it easier to clean and improving the practicality of the device.

[0040] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0042] like Figures 1 to 5 As shown, this embodiment proposes a pipe cutting device for water conservancy and hydropower engineering, including a base 1. Support legs are fixedly connected to the four corners of the bottom of the base 1. A support structure 2 is provided on one side of the top of the base 1. The support structure 2 includes support rods 21 fixedly connected to the front and rear ends of one side of the top of the base 1. A double-acting cylinder 22 is vertically arranged on the opposite side of the top of the support rods 21. Clamping seats 23 are fixedly connected to the two output ends of the double-acting cylinder 22. A V-shaped limiting groove 24 is opened on the opposite side of the clamping seats 23. The V-shaped limiting groove 24 can limit the water conservancy pipe to the left and right. Multiple clamping rollers 25 are rotatably connected to both sides of the inner wall of the V-shaped limiting groove 24. The double-acting cylinder 22 drives the two clamping seats 23 to move simultaneously towards or away from each other, clamping water conservancy pipes of different diameters. At this time, the axial height of the pipe remains unchanged, making the cutting process more stable.
[0043] A rotating structure 3 is provided on the other side of the top of the base 1. The rotating structure 3 includes a mounting plate 31 located on the other side of the top of the base 1. A turntable 32 is rotatably connected to one side of the top of the mounting plate 31, and a motor 33 is fixedly mounted on the other side of the top of the mounting plate 31. A motor mounting bracket is fixedly connected to the other side of the mounting plate 31, and the motor 33 is mounted on the motor mounting bracket. The output end of the motor 33 is fixedly connected to the turntable 32. A mounting groove 34 is provided inside the turntable 32. Two symmetrically arranged rectangular through holes 341 are provided on one side of the mounting groove 34. A bidirectional screw 35 is rotatably connected between the top and bottom of the inner wall of the mounting groove 34. One end of the bidirectional screw 35 passes through the mounting groove 34 and the other end is fixedly connected to a motor 36. The turntable 32 has a motor mounting groove inside, and the motor 36... Installed inside the motor mounting slot, the threaded portion of the bidirectional screw 35 is threadedly connected to a U-shaped rod 37. The U-shaped rod 37 is slidably connected in the rectangular through hole 341. An arc-shaped clamping block 38 is fixedly connected to the end of the U-shaped rod 37. Anti-slip pads are provided on opposite sides of the arc-shaped clamping blocks 38 to improve the clamping effect. The motor 36 drives the bidirectional screw 35 to rotate, which in turn drives the two U-shaped rods 37 to move simultaneously towards or away from each other, thereby driving the two arc-shaped clamping blocks 38 to clamp and fix one end of the pipe. When cutting the pipe, the motor 33 is started to drive the turntable 32 to rotate, which in turn drives the pipe to rotate. After the pipe rotates, the cutting disc 64 can perform a circumferential cut on the pipe. The pipe can be rotated and cut at the same time, and the pipe can be cut in one go.
[0044] The bottom of the rotating structure 3 is provided with an adjustment structure 4. The adjustment structure 4 includes a groove 41 on the other side of the top of the base 1. The inner walls of the groove 41 are rotatably connected to the lead screw 42. The other side of the base 1 is fixedly installed with a motor 43. The other side of the base 1 is fixedly connected with a motor mounting bracket. The motor 43 is mounted on the motor mounting bracket. The output end of the motor 43 is fixedly connected to the lead screw 42. The lead screw 42 is threadedly connected to a slider 44. The slider 44 is fixedly connected to the bottom of the mounting plate 31. The motor 43 drives the lead screw 42 to rotate. The lead screw 42 drives the slider 44 to move left and right, which in turn drives the mounting plate 31 to move left and right, thereby facilitating the adjustment of the cutting position.
[0045] A bracket 5 is fixedly connected to the top of the base 1 near the support structure 2. A cutting structure 6 is provided on the top of the bracket 5. The cutting structure 6 includes a lowering cylinder 61 fixedly connected to the top of the bracket 5. An outer cover 62 is fixedly connected to the output end of the lowering cylinder 61. Limiting rods are fixedly connected to the front and rear sides of the top of the outer cover 62. The limiting rods pass through the top of the bracket 5. A motor 63 is fixedly installed on the other side of the outer cover 62. A motor mounting bracket is fixedly connected to the other side of the outer cover 62. The motor 63 is installed on the motor mounting bracket. A cutting disc 64 is fixedly connected to the output end of the motor 63. The cutting disc 64 is located inside the outer cover 62. The lowering cylinder 61 drives the outer cover 62 to move downward. At the same time, the motor 63 is started to drive the cutting disc 64 to rotate. The rotating cutting disc 64 cuts the pipe.
[0046] The base 1 has a debris collection structure 7 at its bottom. The debris collection structure 7 includes a collection box 71 fixedly connected to one side of the bottom of the base 1. The collection box 71 has a sealed door on one side, and the bottom of the inner wall of the collection box 71 is inclined to facilitate the removal of collected debris. A filter screen 72 is fixedly installed on the other side of the collection box 71, and a negative pressure air compressor 73 is fixedly installed on the other side of the collection box 71. The filter screen 72 prevents sucked-in debris from entering the negative pressure air compressor 73. A suction pipe 74 is fixedly connected to the top of the collection box 71, and the suction pipe 74 extends to the top of the base 1 and its end... A dust collection plate 75 is fixedly connected to the bottom front and rear sides of the bracket 5. When the negative air compressor 73 is started, it will continuously output the air inside the collection box 71 to the outside. At this time, there will be a certain negative pressure inside the collection box 71, so that the dust collection pipe 74 can transmit the negative pressure inside the collection box 71 to the dust collection plate 75. During the cutting process, the debris at the pipe cutting end will also fall into the dust collection plate 75 due to gravity and the negative pressure below, and be transmitted to the collection box 71 by the dust collection pipe 74 below, thereby reducing the pipe debris residue on the surface of the base 1.
[0047] In practical implementation, this utility model is used by first starting motor 36 to drive the bidirectional screw 35 to rotate. The bidirectional screw 35 drives two U-shaped rods 37 to move simultaneously towards or away from each other, thereby driving two arc-shaped clamping blocks 38 to clamp and fix one end of the water pipe. Next, starting motor 43 drives lead screw 42 to rotate, which drives slider 44 to move left and right, thus facilitating adjustment of the cutting position. Then, starting double-acting cylinder 22 drives two clamping seats 23 to move simultaneously towards or away from each other, clamping water pipes of different diameters and making the cutting process more stable. After that, starting lower cylinder 61 drives outer cover 62 to move downward, and simultaneously starting motor 63 drives cutting disc 64 to rotate. The rotating cutting disc 64 clamps the pipe. During the cutting process, the negative pressure compressor 73 is activated, creating negative pressure inside the collection box 71. This negative pressure then forms between the suction pipe 74 and the suction plate 75. As the pipe is being cut, debris from the cut end falls into the suction plate 75 due to gravity and the negative pressure below, and is then transported to the collection box 71 by the suction pipe 74. This reduces pipe debris residue on the surface of the base 1, making cleaning easier. Simultaneously, the motor 33 is activated to rotate the turntable 32, which in turn rotates the pipe. The pipe can be cut while rotating, allowing for a one-time cut. This avoids the need for manual adjustment and clamping of the pipe and manual rotation of the pipe in existing devices, saving time and effort and improving work efficiency.

The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. To ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.
