Description

Technical Field

[0001] This utility model belongs to the field of steel pipe cutting technology, specifically relating to a steel pipe cutting device for sewage treatment construction projects. Background Technology

[0002] During the construction of sewage treatment plants, a large number of pipes are required. Pipe cutting is a basic and critical process. The cutting process requires the pipes to be precisely cut to a specific length according to the engineering design requirements in order to meet the construction needs of pipeline laying and connection.

[0003] The process of securing the pipe before cutting is crucial. Specialized clamps are usually needed to firmly hold the pipe on the cutting device. Stable securing not only ensures the accuracy of the cutting dimensions but also reduces problems such as tool wear and cutting surface deformation caused by pipe shaking. It also ensures the safety of the operators.

[0004] Most cutting devices on the market currently use a "completely fixed" method when clamping pipes, meaning that the clamps rigidly constrain the pipes to maximize stability during cutting. However, this design has significant drawbacks when multiple cuts are needed on a single pipe section: after each cut, the clamps must be manually or automatically tightened and the pipe position adjusted before being re-clamped and fixed. This series of operations is not only cumbersome but also time-consuming, reducing overall cutting efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a steel pipe cutting device for sewage treatment construction projects, which solves the problem that in the prior art, when the cutting device cuts a section of pipe multiple times, it is necessary to frequently control the clamping and loosening of the clamp.

[0006] The technical solution adopted by this utility model is a steel pipe cutting device for sewage treatment construction engineering, including a cutting table. A U-shaped groove is opened on the top surface of the cutting table. A cutting component that moves perpendicular to the U-shaped groove is installed on the cutting table. The cutting component includes a cutting motor. A saw blade is fixedly connected to the motor shaft of the cutting motor. The cutting motor is mounted on a sliding mechanism. The sliding mechanism is installed at the bottom of the top plate of the cutting table. The saw blade can extend out of the strip hole provided in the top plate of the cutting table. A positioning and feeding mechanism for pushing the steel pipe and a protective mechanism are provided above the cutting table. The protective mechanism is located directly above the strip hole.

[0007] Furthermore, the positioning and feeding mechanism includes a support platform. The support platform is vertically slidably connected to the top of the cutting table via two vertical plates at both ends. A rotating rod is rotatably connected between the two vertical plates of the support platform. Multiple positioning drive wheels are fixedly connected to the rotating rod. Each positioning drive wheel has an annular groove facing the U-shaped groove. A worm gear is fixedly connected to one end of the rotating rod. A servo motor is fixedly connected to the top of the support platform. A worm gear meshing with the worm gear is fixedly connected to the motor shaft of the servo motor. A threaded sleeve is fixedly connected to the left side of the support platform. A threaded rod driving the support platform to rise and fall is vertically helically connected to the threaded sleeve. A knob is fixedly connected to the top of the threaded rod, and the lower end of the threaded rod is rotatably connected to the cutting table. Rotating the threaded rod can drive the support platform to rise and fall.

[0008] Furthermore, the annular groove is a V-shaped cross-section groove, and a silicone layer is provided on the groove surface.

[0009] Furthermore, the protective mechanism includes a crossbar, one end of which is fixedly connected to a support platform, and the other end of which is fitted with a protective cover. The bottom of the protective cover has an open structure, and the protective cover is located directly above the strip-shaped hole.

[0010] Furthermore, a sliding rod is vertically slidably connected to the other end of the crossbar, a protective cover is fixedly connected to the bottom end of the sliding rod, a spring is fixedly connected to the top of the protective cover, and the spring is sleeved on the sliding rod with its end away from the protective cover fixedly connected to the bottom of the crossbar.

[0011] Furthermore, the sliding mechanism includes a sliding plate, which is slidably connected to a sliding groove provided at the bottom of the top plate of the cutting table. The cutting motor is fixedly connected to the lower surface of the sliding plate, and a handle is fixedly connected to the side of the sliding plate. The handle passes through one end of the sliding groove and can drag the sliding plate along the sliding groove along its length.

[0012] Furthermore, the outer wall of the silicone layer is fixedly connected with a protrusion.

[0013] This utility model has the following beneficial effects: 1) This utility model, through the design of the positioning and feeding mechanism, can transport the pipe without releasing the clamping action of the pipe, thereby extending the remaining pipe to the other side of the saw blade so that the saw blade can continue to cut. This not only makes it more convenient to use, but also improves the continuity of pipe cutting, thereby greatly improving the efficiency of pipe cutting. 2) Through the design of the protective mechanism, this utility model can cover the saw blade while clamping the pipe, preventing sparks generated during the cutting process from flying around and accidentally injuring the surrounding workers, thus enabling workers to cut pipes under safe working conditions.

[0016] The present invention will be further explained below with reference to the accompanying drawings to enable those skilled in the art to better understand it.

[0017] Example 1, refer to as follows Figure 1 - Figure 6 As shown, a steel pipe cutting device for sewage treatment construction includes a cutting table 1. A U-shaped groove 2 is provided on the top surface of the cutting table 1. The pipe to be cut is placed inside the U-shaped groove 2, and the pipe can be clamped by the positioning drive wheel 63. A cutting component that moves perpendicular to the U-shaped groove 2 is installed on the cutting table 1. The cutting component includes a cutting motor 3. A saw blade 5 is fixedly connected to the motor shaft 4 of the cutting motor 3. The cutting motor 3 is installed on a sliding mechanism, which is installed at the bottom of the top plate of the cutting table 1. The saw blade 5 can extend out of the strip hole 101 provided on the top plate of the cutting table 1. The cutting motor 3 is started to drive the motor shaft 4 to rotate, so that the motor shaft 4 drives the saw blade 5 to rotate at high speed. The pipe inside the U-shaped groove 2 can be cut by the movement and high speed rotation of the saw blade 5. A positioning feeding mechanism 6 and a protective mechanism 7 are provided above the cutting table 1 to push the steel pipe. The protective mechanism 7 is located directly above the strip hole 101.

[0018] The positioning and feeding mechanism 6 includes a support platform 61. The two ends of the support platform 61 are vertically slidably connected to vertical slots 103 on the top plate of the cutting table 1 via two vertical plates. The vertical plates can move up and down within the slots, acting as guide rails. A rotating rod 62 is rotatably connected between the two vertical plates of the support platform 61. Multiple positioning drive wheels 63 are fixedly connected to the rotating rod 62. Each positioning drive wheel 63 has an annular groove 6301 facing the U-shaped groove 2. A worm gear 64 is fixedly connected to one end of the rotating rod 62. The support platform 61... A servo motor 65 is fixedly connected to the top. The motor shaft of the servo motor 65 is fixedly connected to a worm 66 that meshes with a worm gear 64. Starting the servo motor 65 drives the worm 66 to rotate. Simultaneously, the worm 66 drives the meshing worm gear 64 to rotate. The worm gear 64, in turn, drives a rotating rod 62 to rotate synchronously on the inner wall of the support platform 61. The rotating rod 62, in turn, drives a positioning drive wheel 63 to rotate synchronously. A threaded sleeve 67 is fixedly connected to the left side of the support platform 61. The threaded sleeve 67 is vertically helically connected to a device that drives the support platform to rise and fall. A threaded rod 68 has a knob 69 fixedly connected to its top end. The lower end of the threaded rod 68 is rotatably connected to a rotary table 10 fixedly connected to the cutting table 1. The rotary table 10 is provided with a blind hole 1001. The lower end of the threaded rod 68 has an annular groove 6801. After the smooth rod extends into the blind hole 1001, a set screw 11 passes through the side wall of the blind hole 1001 and extends into the annular groove 6801, which can rotate the threaded rod to prevent it from coming off. Rotating the threaded rod can drive the support table 61 to rise and fall. The annular groove 6301 is a V-shaped cross-section groove, and a silicone layer is provided on the groove surface. 610. A raised strip 611 is provided on the outside of the silicone layer 610. The raised strip 611 is made of silicone material. The positioning drive wheel 63 and the U-shaped groove 2 can clamp the pipe at three points. The rotation of the positioning drive wheel 63, together with the silicone layer 610 and the raised strip 611, can push the pipe, so that the pipe moves on the inner wall of the U-shaped groove 2, so that the saw blade 5 can continue to cut the remaining pipe. The raised strip 611 and the silicone layer 610 can increase the friction between the positioning drive wheel 63 and the pipe, which can not only improve the stability of the positioning drive wheel 63 clamping the pipe.

[0019] The protective mechanism 7 includes a crossbar 71, one end of which is fixedly connected to the support platform 61, and the other end of which is equipped with a protective cover 73. The bottom of the protective cover 73 is an open structure. The protective cover 73 is located directly above the strip hole 101. The protective cover 73 can cover the saw blade 5 to prevent sparks generated during the cutting process from splashing and injuring the surrounding workers.

[0020] To maintain elastic pressure between the protective cover and the upper surface of the cutting table, a slide rod 72 is vertically slidably connected to the other end of the crossbar 71. The bottom end of the slide rod 72 is fixedly connected to the protective cover 73, and the top of the protective cover 73 is fixedly connected to the spring 74. The spring 74 is sleeved on the slide rod 72, and the end away from the protective cover 73 is fixedly connected to the bottom of the crossbar 71. While the support table 61 slides on the inner wall of the cutting table 1, the protective cover 73 can be moved synchronously by the connection between the crossbar 71 and the spring 74. An anti-loosening nut (not shown) is provided at the top of the slide rod 72.

[0021] The sliding mechanism includes a slide plate 8, which is slidably connected to a sliding groove 102 provided at the bottom of the top plate of the cutting table 1. The cutting motor 3 is fixedly connected to the lower surface of the slide plate 8. A handle 9 is fixedly connected to the side of the slide plate 8. The handle 9 passes through one end of the sliding groove 102 and can drag the slide plate 8 along the length of the sliding groove 102. Pulling the handle 9 causes the slide plate 8 to slide on the inner wall of the cutting table 1. While the slide plate 8 is sliding, it will drive the cutting motor 3 to move synchronously, thereby enabling the motor shaft 4 and the saw blade 5 to move. A T-shaped part 801 is provided at the top of the slide plate. The two flanges at the top of the T-shaped part 801 are movably embedded in the strip-shaped sliding grooves 1021 provided on both sides of the sliding groove 102, which can realize the directional sliding connection between the slide plate and the sliding groove.

[0022] Working principle: Place the pipe to be cut inside the U-shaped groove 2, adjust the cutting length of the pipe, and then rotate the threaded rod 68 by knob 69. This causes the threaded rod 68 to drive the threaded sleeve 67 connected to it to move downwards. The threaded sleeve 67 causes the support table 61 to slide downwards in the vertical strip hole 103 of the cutting table 1. At this time, the support table 61 will drive the rotating rod 62 to move downwards synchronously. The rotating rod 62 will then drive the positioning drive wheel 63 to move downwards synchronously until the positioning drive wheel 63 drives the silicone layer 610 to press against the outer wall of the pipe. Then stop rotating the threaded rod 68. At this time, the positioning drive wheel 63 can press the pipe tightly inside the U-shaped groove 2. Then start the cutting motor 3 to drive the motor shaft 4 to rotate, which in turn drives the saw blade 5 to rotate at high speed. Then pull the handle 9 to make the slide plate 8 slide on the inner wall of the cutting table 1. As the slide plate 8 slides, it will drive the cutting motor 3 to move synchronously. At this time, the cutting motor 3 will drive the motor shaft 4 and the saw blade 5 to move synchronously. The movement of the saw blade 5 can cut the pipe inside the U-shaped groove 2.

[0023] After the pipe cutting is completed, first turn off the cutting motor 3, and then use the handle 9 and the slide plate 8 to move and reset the cutting motor 3. Then start the servo motor 65 to drive the worm gear 66 to rotate. As the worm gear 66 rotates, it drives the worm wheel 64 that meshes with it to rotate. As the worm wheel 64 rotates, it drives the rotating rod 62 to rotate synchronously on the inner wall of the support platform 61. As the rotating rod 62 rotates, it drives the positioning drive wheel 63 to rotate synchronously. As the positioning drive wheel 63 rotates, it uses the friction of the silicone layer 610 to push the pipe, so that the pipe moves on the inner wall of the U-shaped groove 2. This allows the remaining pipe to be extended to the other side of the saw blade 5, so that the saw blade 5 can continue cutting without releasing the clamp on the pipe, making it more convenient to use.

[0024] As the support platform 61 slides downward through the vertical slot of the cutting table 1, it drives the crossbar 71 to move downward simultaneously. The crossbar 71, in conjunction with the spring 74, moves the protective cover 73 downward, allowing its bottom to adhere to the upper surface of the cutting table 1. When the protective cover 73 is in contact with the upper surface of the cutting table 1, and the support platform 61 continues to slide, it drives the crossbar 71 to slide downward against the outer wall of the slide bar 72. Simultaneously, the crossbar 71 compresses the spring 74. The elasticity of the spring 74 then pushes the protective cover 73, ensuring its bottom is firmly against the upper surface of the cutting table 1. The protective cover 73 then covers the saw blade 5, preventing sparks from flying and injuring nearby workers during the cutting process.
