Description

Technical Field

[0001] This utility model relates to the field of steel pipe cutting technology, specifically a safety steel pipe cutting device with a limiting structure. Background Technology

[0002] The main functions of steel pipes include transporting fluids and powdery solids, exchanging heat energy, and manufacturing mechanical parts and containers. Steel pipes possess high strength and corrosion resistance, making them excellent in various applications.

[0003] Steel pipes have a wide range of applications in various fields. In the construction industry, steel pipes are used to build main structures, bridges, highway guardrails, etc.; in the machinery manufacturing industry, steel pipes are used to manufacture various mechanical parts, such as auto parts and boilers; in bridge construction, steel pipes are used for supporting structures and connecting components; in living facilities, steel pipes are used for drinking water facilities and environmental protection facilities; in the steel industry, steel pipes are used to manufacture various mechanical parts and structural materials.

[0004] Depending on the application of the steel pipe, it needs to be processed. During the processing of the steel pipe, a cutting device is required to cut it.

[0005] For example, a bridge construction steel pipe cutting device with convenient limiting, as described in application number 201710580329.3, achieves convenient limiting of the steel pipe cutting device by setting up an insert rod, support block, limiting block, locking block, sliding plate, slider, motor, lead screw, sleeve, nut, return spring, and spring, thereby facilitating the processing of steel pipes and improving the efficiency of the bridge construction steel pipe cutting device. However, this device still has certain shortcomings.

[0006] When it is necessary to cut steel pipes at different locations, the position of the steel pipes needs to be adjusted manually, which results in low cutting efficiency and low practicality.

[0007] Therefore, we propose a safety steel pipe cutting device with a limiting structure to solve the problems mentioned above. Utility Model Content

[0008] The purpose of this utility model is to provide a safe steel pipe cutting device with a limiting structure, so as to solve the problem mentioned in the background art that when steel pipes need to be cut at different positions, the position of the steel pipe needs to be manually adjusted, resulting in low cutting efficiency and low practicality.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a safety steel pipe cutting device with a limiting structure, comprising a worktable, a first support frame installed above the worktable, and a cutting assembly installed below the first support frame via a first electric telescopic rod;

[0010] The workbench is equipped with a shelf on its upper surface, and a protective rubber pad is installed on the upper left side of the shelf. A second support frame is installed on the workbench, and a first adjusting threaded rod is installed on both the front and rear sides of the second support frame. A second adjusting threaded rod is installed above the second support frame, and a connecting frame is installed below the second adjusting threaded rod via a bearing seat.

[0011] The connecting frame is equipped with a limiting roller through a rotating shaft assembly. The left side of the limiting roller has a sliding groove. An electromagnetic block is installed inside the connecting frame.

[0012] A support plate is installed above the workbench, and a second electric telescopic rod is installed on the right side of the support plate, and a push block is installed on the right side of the second electric telescopic rod.

[0013] Preferably, four casters are installed under the workbench, and the casters are arranged in a rectangular structure.

[0014] The above structural design allows for easy movement of the cutting device via casters, making it more convenient and labor-saving.

[0015] Preferably, a material collection trough is provided on the upper right surface of the platform, and the material collection trough is located below the cutting assembly.

[0016] With the above structural design, during the cutting process of the steel pipe, the cut part of the steel pipe can fall into the collection trough, thereby preventing the steel pipe from rolling to the ground, causing damage to the steel pipe, or hitting the feet of the workers.

[0017] Preferably, the second support frame is located above the protective rubber pad, the first adjusting threaded rod is threadedly connected to the second support frame, and limit plates are installed on the opposite side of the first adjusting threaded rod.

[0018] With the above structural design, when cutting the steel pipe, the steel pipe is placed on a protective rubber pad. The protective rubber pad protects the steel pipe and prevents it from slipping. Then, the first adjusting threaded rod is rotated, which moves the limiting plate towards the steel pipe, so that the distance between the two limiting plates and the steel pipe is about 2mm.

[0019] Preferably, the limiting plates are designed in a circular structure and are parallel to each other.

[0020] With the above structural design, the limiting plate can limit the movement of the steel pipe when the cutting position is moved, so that the steel pipe will not deviate when it moves.

[0021] Preferably, the limiting roller is rotatably connected to the rotating shaft assembly, and the number of limiting rollers is set to 1-3.

[0022] With the above structural design, when the electromagnetic block is energized, it attracts and fixes the limiting roller. Rotating the second adjusting threaded rod causes the connecting frame below to move downward, thereby causing the limiting roller inside the connecting frame to move downward. The limiting roller is pressed tightly against the steel pipe, and the friction between the limiting roller and the steel pipe is used to limit the steel pipe, making it less likely to deviate during cutting.

[0023] Preferably, the electromagnetic block and the sliding groove abut against each other, and when the electromagnetic block is de-energized, the electromagnetic block and the sliding groove are in a sliding connection.

[0024] With the above structural design, when the electromagnetic block is de-energized, the steel pipe can drive the limiting roller to roll as it moves. At this time, the groove on the limiting roller rotates along the electromagnetic block, and the electromagnetic block can limit the rolling of the limiting roller. Therefore, when the position of the steel pipe needs to be moved, there is no need to adjust the position of the limiting roller.

[0025] Compared with the prior art, the beneficial effects of this utility model are: the safety steel pipe cutting device with a limiting structure:

[0026] 1. A second electric telescopic rod is provided. When it is necessary to cut the steel pipe at different positions, the electromagnetic block is de-energized and then the second electric telescopic rod is activated. The second electric telescopic rod drives the push block to move to the right, and the push block pushes the steel pipe to move to the right. After the position of the steel pipe is adjusted, the electromagnetic block is energized so that the electromagnetic block can attract and fix the limit roller, thus eliminating the need for manual adjustment of the position of the steel pipe.

[0027] 2. An electromagnetic block is provided. When the electromagnetic block is energized, it attracts and fixes the limiting roller. Rotating the second adjusting threaded rod causes the connecting frame below to move downward, thereby causing the limiting roller inside the connecting frame to move downward. The limiting roller is pressed tightly against the steel pipe, and the friction between the limiting roller and the steel pipe is used to limit the steel pipe, making it less likely to deviate during cutting.

[0028] 3. A material collection trough is provided. During the cutting process of the steel pipe, the cut part of the steel pipe can fall into the material collection trough, thereby preventing the steel pipe from rolling to the ground, causing damage to the steel pipe, or hitting the feet of the workers.

[0029] 4. A limiting plate is installed. When cutting the steel pipe, the steel pipe is placed on a protective rubber pad. The protective rubber pad protects the steel pipe and prevents it from slipping. Then, the first adjusting threaded rod is rotated, which moves the limiting plate towards the steel pipe, so that the distance between the two limiting plates and the steel pipe is about 2mm. The limiting plate helps to limit the movement of the steel pipe when the cutting position is moved, preventing the steel pipe from deviating during movement. Attached Figure Description

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Please see Figures 1-5This utility model provides a technical solution: a safety steel pipe cutting device with a limiting structure, including a workbench 1, casters 2, a first support frame 3, a first electric telescopic rod 4, a cutting assembly 5, a storage platform 6, a material collection trough 7, a protective rubber pad 8, a second support frame 9, a first adjusting threaded rod 10, a limiting plate 11, a second adjusting threaded rod 12, a bearing seat 13, a connecting frame 14, a rotating shaft assembly 15, a limiting roller 16, a sliding groove 17, an electromagnetic block 18, a support plate 19, a second electric telescopic rod 20, and a push block 21. Casters 2 are installed below the workbench 1, and four casters 2 are arranged in a rectangular structure. The casters 2 facilitate the movement of the cutting device, making it more convenient and labor-saving. The first support frame 3 is installed above the workbench 1, and the cutting assembly 5 is installed below the first support frame 3 via the first electric telescopic rod 4.

[0038] A storage platform 6 is installed on the upper surface of the workbench 1. A material collection trough 7 is provided on the upper right side of the storage platform 6, located below the cutting assembly 5. During the cutting process, the cut portion of the steel pipe can fall into the material collection trough 7, preventing the steel pipe from rolling to the ground, causing damage, or injuring the worker's feet. A protective rubber pad 8 is installed on the upper left side of the storage platform 6. A second support frame 9 is installed on the workbench 1, located above the protective rubber pad 8. A first adjusting threaded rod 10 is threadedly connected to the second support frame 9, and limit plates 11 are installed on opposite sides of the first adjusting threaded rod 10. When cutting the steel pipe, the steel pipe is placed on the protective rubber pad 8, which provides protection against damage. The steel pipe serves as a protective element and also prevents slippage. Then, the first adjusting threaded rod 10 is rotated, which causes the limiting plate 11 to move towards the steel pipe, making the distance between the two limiting plates 11 and the steel pipe about 2mm. The limiting plates 11 have a circular structure design and are parallel to each other. The limiting plates 11 can limit the movement of the steel pipe when the cutting position is moved, preventing the steel pipe from shifting. The first adjusting threaded rod 10 is installed on both the front and rear sides of the second support frame 9, and the second adjusting threaded rod 12 is installed on the top of the second support frame 9. The connecting frame 14 is installed below the second adjusting threaded rod 12 through the bearing seat 13.

[0039] Inside the connecting frame 14, a limiting roller 16 is installed via a rotating shaft assembly 15. The limiting roller 16 is rotatably connected to the rotating shaft assembly 15, and only one limiting roller 16 is provided. When the electromagnetic block 18 is energized, it attracts and fixes the limiting roller 16. Rotating the second adjusting threaded rod 12 causes the connecting frame 14 below to move downwards, thereby causing the limiting roller 16 inside the connecting frame 14 to move downwards. The limiting roller 16 applies tight low pressure to the steel pipe, and the friction between the limiting roller 16 and the steel pipe limits the steel pipe, preventing it from being cut. The cutting process is less prone to deviation. A groove 17 is provided on the left side of the limiting roller 16. An electromagnetic block 18 is installed inside the connecting frame 14. The electromagnetic block 18 and the groove 17 abut against each other. When the electromagnetic block 18 is de-energized, the electromagnetic block 18 and the groove 17 are slidably connected. When the electromagnetic block 18 is de-energized, the steel pipe can drive the limiting roller 16 to roll when it moves. At this time, the groove 17 on the limiting roller 16 rotates along the electromagnetic block 18. The electromagnetic block 18 can limit the rolling of the limiting roller 16, so that when the position of the steel pipe needs to be moved, there is no need to adjust the position of the limiting roller 16.

[0040] A support plate 19 is installed above the workbench 1, and a second electric telescopic rod 20 is installed on the right side of the support plate 19, and a push block 21 is installed on the right side of the second electric telescopic rod 20.

[0041] Working Principle: When using this safety steel pipe cutting device with a limiting structure, firstly, when cutting the steel pipe, the steel pipe is placed on the protective rubber pad 8. The protective rubber pad 8 serves two purposes: protecting the steel pipe and preventing it from slipping. Then, the first adjusting threaded rod 10 is rotated, which moves the limiting plate 11 towards the steel pipe, making the distance between the two limiting plates 11 and the steel pipe approximately 2mm. When the electromagnetic block 18 is energized, it attracts and fixes the limiting roller 16. Then, the second adjusting threaded rod 12 is rotated... 12 drives the lower connecting frame 14 to move downward, thereby driving the limiting roller 16 inside the connecting frame 14 to move downward. The limiting roller 16 applies tight low pressure to the steel pipe, thereby limiting the steel pipe through the friction between the limiting roller 16 and the steel pipe, making it less likely for the steel pipe to deviate during cutting. Then, the first electric telescopic rod 4 and the cutting component 5 are activated. The first electric telescopic rod 4 drives the cutting component 5 to move downward to cut the steel pipe. The cut part of the steel pipe can fall into the collection trough 7, thereby preventing the steel pipe from rolling to the ground, causing damage to the steel pipe and hitting the workers' feet.

[0042] When it is necessary to cut the steel pipe at different locations, the electromagnetic block 18 is de-energized, and then the second electric telescopic rod 20 is activated. The second electric telescopic rod 20 drives the push block 21 to move to the right, and the push block 21 pushes the steel pipe to the right. After the position of the steel pipe is adjusted, the electromagnetic block 18 is energized, so that the electromagnetic block 18 attracts and fixes the limiting roller 16, thus eliminating the need for manual adjustment of the position of the steel pipe. This completes a series of tasks. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
