Description

Technical Field

[0001] This utility model relates to large-scale steel structure processing equipment, and more particularly to a multi-axis linkage vertical steel pipe intersection line cutting device. Background Technology

[0002] Vertical steel pipes are steel pipes installed or used in a vertical state. They have a wide range of applications and play an important role in construction, machinery manufacturing, and energy. Structurally, vertical steel pipes are made of high-quality steel. Depending on different usage requirements, their pipe diameter, wall thickness, length, and material properties vary. The pipe diameter can be as small as a few millimeters or as large as several meters, and the wall thickness can also be thin or thick to adapt to different pressure and stress conditions.

[0003] A search revealed Chinese patent publication number CN221247373U, which discloses a wire cutting device for steel pipe fittings. The device includes a worktable, a guide rail fixedly connected to the upper surface of the worktable, a slider slidably connected to the top of the guide rail, a slide plate fixedly connected to the top of the slider, and a bracket for supporting the steel pipe fitting fixedly connected to the top of the slide plate. The bracket has a groove on its top. A fixing mechanism for fixing the steel pipe fitting is provided on the left side of the guide rail, and a wire cutting mechanism is fixedly connected to the rear side of the guide rail. This invention, by setting a fixing mechanism, facilitates the fixing of one end of the steel pipe fitting, and through the guide rail, slider, and slide plate... The interaction between the device and the bracket facilitates support for the other end of the steel pipe. Simultaneously, the wire cutting mechanism, with its laser cutter moving laterally under the action of the lead screw, drive motor, and moving block, allows for convenient and efficient cutting of the steel pipe. However, this device is only suitable for cutting steel pipes of conventional sizes and shapes. The structure of the fixing mechanism and bracket lacks adjustment capabilities, making it difficult to adapt to steel pipes with a diameter of 1.25 meters or more. When dealing with large-diameter steel pipes, the bracket slot size is insufficient, and the fixing mechanism cannot provide adequate clamping force, limiting its application in large-scale steel structure projects. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-axis linkage vertical steel pipe intersection line cutting device, which aims to improve the problem that the existing technology lacks adjustment function, is difficult to adapt to large-diameter steel pipes, and limits its application in large steel structure projects.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-axis linkage vertical steel pipe intersecting line cutting device, comprising a processing table and a vertical steel pipe body. A drive motor is fixedly connected to the top front side of the processing table, and a drive rod is fixedly connected to the output end of the drive motor. A threaded rope groove is opened on the outside of the drive rod, and a cutting rope is arranged inside the threaded rope groove. Two guide pulleys are fixedly connected to the left and right front ends of the processing table, and reversing pulleys are fixedly connected to the left and right ends of the front side of the processing table. Mounting frames are fixedly connected to the top left and right sides of the processing table. Electric push rods are fixedly connected inside the two mounting frames. Pressure plates are fixedly connected to the bottom ends of the two electric push rods. Adjusting pulleys are fixedly connected to the bottom of the two pressure plates. The cutting rope passes through the interior of multiple guide pulleys, two reversing pulleys, and two adjusting pulleys. The rear end of the cutting rope is attached to the rear side of the vertical steel pipe body. A fixing mechanism is provided on the rear side of the processing table.

[0006] The above technical solution achieves high-precision intersecting line cutting of large-diameter steel pipes by using a drive motor to drive the drive rod, guiding the trajectory with guide pulleys and reversing pulleys, adjusting the cutting depth with an electric push rod, and using pressure plate feedback data for precise control. This ensures stable operation of the cutting rope, precise adjustment of the cutting position and depth, and adaptability to different pipe diameters and cutting requirements. Compared with traditional cutting methods, it significantly improves cutting efficiency and accuracy.

[0007] As a further description of the above technical solution:

[0008] The fixing mechanism includes a U-shaped plate, which is fixedly connected to the front side of the inside of the processing table. Hinges are fixedly connected to the rear ends of both sides of the processing table. Claws are fixedly connected to the rear ends of both hinges. Fixing plates are fixedly connected to the rear ends of both claws. A fastening bolt passes through the right side of the right-end fixing plate. The end of the fastening bolt is threaded into the inside of the left-end fixing plate. Two adjusting screws are threaded to the outside of both claws. A rubber head is fixedly connected to the adjacent end of each of the two adjusting screws.

[0009] The above technical solution involves: initially positioning the vertical steel pipe body using a U-shaped plate; rotating the gripper via a hinge to encircle the steel pipe; tightening bolts passing through the fixing plate to tighten the gripper and prevent the steel pipe from swaying left and right; and adjusting the screw to drive the rubber head to fit the surface of the steel pipe, adapting to different pipe diameters. This achieves a stable fixing effect for vertical steel pipe bodies of various specifications on the processing table. The fixing method is easy to operate, and through the coordinated action of multiple components, it effectively restricts the multi-directional displacement of the steel pipe and enhances the stability during cutting.

[0010] As a further description of the above technical solution:

[0011] A tachometer is fixedly connected to the front side of the processing table, and the tachometer is electrically connected to the drive motor.

[0012] The above technical solution involves electrically connecting the tachometer to the drive motor, which allows for real-time monitoring of the drive motor's operating data during cutting operations. The tachometer converts the drive motor's speed information into an electrical signal and feeds it back to the tachometer, preventing equipment damage or reduced cutting accuracy due to overload.

[0013] As a further description of the above technical solution:

[0014] Each of the multiple adjusting screws has an O-ring fixedly connected to one of its opposite ends, and the O-rings are designed with anti-slip features.

[0015] The above technical solution involves fixing the O-ring to the end of the adjusting screw. Its anti-slip design makes it easy for operators to hold. When adjusting the fixing mechanism, rotating the O-ring drives the adjusting screw to rotate, which can accurately adjust the contact position and pressure between the rubber head and the vertical steel pipe body, achieving a fast and labor-saving tightening operation.

[0016] As a further description of the above technical solution:

[0017] Two U-shaped straps are fixedly connected to the outside of each of the two electric push rods, and multiple U-shaped straps are fixedly connected to the inside of the two mounting brackets respectively.

[0018] The above technical solution involves installing a U-shaped strap between the electric push rod and the mounting frame to fix and limit the movement of the electric push rod, thus securing it firmly to the inside of the mounting frame and preventing displacement or shaking during extension and retraction, thereby improving the overall reliability of the cutting device.

[0019] As a further description of the above technical solution:

[0020] Both mounting brackets are fixedly connected to triangular braces at their rear bottom, and the bottom ends of the two triangular braces are fixedly connected to the left and right rear ends of the top of the processing table, respectively.

[0021] The above technical solution uses a triangular brace to connect the mounting frame and the processing table. By utilizing the stability principle of a triangle, the structural strength of the mounting frame is enhanced. When the electric push rod is working, the stress on the mounting frame is effectively dispersed, preventing it from deforming due to stress and affecting the cutting accuracy.

[0022] As a further description of the above technical solution:

[0023] The rear side of the U-shaped plate adopts an arc design, and the rear side of the U-shaped plate is attached to the front side of the vertical steel pipe body.

[0024] Through the above technical solution: the arc design on the back side of the U-shaped plate fits the front side of the vertical steel pipe body, providing precise positioning support for the steel pipe. During the fixing process, the arc surface fits the outline of the steel pipe, restricting the forward and backward movement of the steel pipe, while sharing the fixing pressure of the clamp. Together with the clamp, they ensure that the steel pipe remains stable during cutting and improve the fixing effect.

[0025] As a further description of the above technical solution:

[0026] The exterior of all the rubber heads is rounded, and the adjacent sides of all the rubber heads are frosted.

[0027] The above technical solution achieves the following: the smooth outer design of the rubber head prevents scratches on the steel pipe surface, the frosted process increases the friction with the steel pipe, and the rubber head is pushed tightly against the steel pipe by adjusting the screw, which can not only firmly fix the steel pipe, but also avoid damage to the steel pipe surface. At the same time, it can be flexibly adjusted according to different pipe diameters to meet the fixing needs of various specifications of vertical steel pipe bodies.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the drive motor drives the drive rod to generate a movement trend of the cutting rope. The guide pulley and the direction-changing pulley guide the trajectory. The electric push rod is linked to adjust the pulley to adjust the cutting depth. At the same time, the pressure plate feeds back data to achieve precise control, realizing the effect of high-precision intersecting line cutting of large-diameter steel pipes. It ensures the stable operation of the cutting rope and accurately adjusts the cutting position and depth. It can adapt to different pipe diameters and cutting needs. Compared with traditional cutting methods, it significantly improves cutting efficiency and accuracy.

[0030] 2. In this utility model, the vertical steel pipe body is initially positioned by a U-shaped plate, the gripper rotates through a hinge to encircle the steel pipe, and the fastening bolt passes through the fixing plate to tighten the gripper, preventing the steel pipe from swaying left and right. The adjusting screw drives the rubber head to fit the surface of the steel pipe, adapting to different pipe diameters, and achieving a stable fixing effect of the processing table on vertical steel pipe bodies of various specifications. The fixing method is easy to operate, and through the coordinated action of multiple components, it effectively restricts the multi-directional displacement of the steel pipe and enhances the stability during cutting.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 3 and Figure 5 An embodiment of this utility model provides a multi-axis linkage vertical steel pipe intersection line cutting device, including a processing table 1 and a vertical steel pipe body 3. A drive motor 4 is fixedly connected to the top front side of the processing table 1. A drive rod 5 is fixedly connected to the output end of the drive motor 4. A threaded rope groove 6 is opened on the outside of the drive rod 5. A cutting rope 7 is arranged inside the threaded rope groove 6. Two guide pulleys 8 are fixedly connected to the left and right front ends of the processing table 1. A reversing pulley 9 is fixedly connected to the left and right ends of the front side of the processing table 1. A mounting frame 10 is fixedly connected to the top left and right sides of the processing table 1. An electric push rod 11 is fixedly connected inside the two mounting frames 10. A pressure-sensing plate 12 is fixedly connected to the bottom end of the two electric push rods 11. An adjusting pulley 13 is fixedly connected to the bottom of the two pressure-sensing plates 12. The cutting rope 7 passes through the interior of multiple guide pulleys 8, two reversing pulleys 9 and two adjusting pulleys 13. The rear end of the cutting rope 7 is attached to the rear side of the vertical steel pipe body 3. A fixing mechanism 2 is arranged on the rear side of the processing table 1.

[0040] Specifically, before the cutting operation, the processing table 1 is fixedly installed on the vertical steel pipe body 3 at a suitable position using the fixing mechanism 2. The drive motor 4 is fixed on the top front side of the processing table 1. When the drive motor 4 is started, its output end drives the drive rod 5 to rotate. The threaded rope groove 6 on the outside of the drive rod 5 provides the movement trajectory for the cutting rope 7. The cutting rope 7 is placed in the threaded rope groove 6. As the drive rod 5 rotates, the cutting rope 7 generates a movement tendency under the action of the threaded rope groove 6. The guide pulleys 8 on the front left and right sides of the processing table 1, the directional pulleys 9 on the front left and right sides, and the adjusting pulleys 13 connected to the pressure-sensing plate 12 at the bottom of the electric push rod 11 on the top left and right sides of the mounting bracket 10 together constitute the guiding and adjusting system of the cutting rope 7. The cutting rope 7 passes through multiple guide pulleys 8, two directional pulleys 9, and two adjusting pulleys 13 in sequence. The guide pulleys 8 ensure that the cutting rope 7 moves stably in the horizontal direction. The height of the pressure-sensing plate 12 and the adjusting pulleys 13 are adjusted by the electric push rod 11 according to the cutting requirements. When the electric push rod 11 extends or retracts, the adjusting pulley 13 drives the cutting rope 7 to move up and down, thereby adjusting the contact position and cutting depth between the cutting rope 7 and the vertical steel pipe body 3. The pressure-sensing plate 12 can sense the tension and pressure changes of the cutting rope 7, realize precise control of the electric push rod 11, and ensure the stability of the cutting process. The rear end of the cutting rope 7 is attached to the rear side of the vertical steel pipe body 3. As the drive rod 5 continues to rotate, the cutting rope 7, guided by each pulley, makes a circular motion around the vertical steel pipe body 3. At the same time, under the adjustment of the electric push rod 11, it realizes horizontal cutting, thereby completing the intersecting line cutting of the large-diameter vertical steel pipe body 3. In the whole cutting process, the stable operation of the drive motor 4, the guiding effect of each pulley, and the precise adjustment of the electric push rod 11 work together to ensure that the cutting rope 7 can perform high-precision cutting of the vertical steel pipe body 3 according to the predetermined trajectory and parameters, meeting the processing requirements of different pipe diameters and intersecting line shapes.

[0041] Reference Figure 1 and Figure 4 The fixing mechanism 2 includes a U-shaped plate 201, which is fixedly connected to the front side of the inside of the processing table 1. The left and right rear ends of the processing table 1 are both fixedly connected to hinges 202. The rear ends of the two hinges 202 are both fixedly connected to grippers 203. The rear ends of the two grippers 203 are both fixedly connected to fixing plates 204. A fastening bolt 205 passes through the right side of the right fixing plate 204. The end of the fastening bolt 205 is threaded into the inside of the left fixing plate 204. The outside of the two grippers 203 are both threadedly connected to two adjusting screws 206. The adjacent ends of the two adjusting screws 206 are both fixedly connected to rubber heads 207.

[0042] Specifically, the U-shaped plate 201 is fixedly connected to the front interior of the processing table 1, providing initial support and positioning for the vertical steel pipe body 3. When the vertical steel pipe body 3 is placed on the processing table 1, its front end can fit against the U-shaped plate 201. The shape of the U-shaped plate 201 can adapt to the circular outline of the steel pipe, playing a certain limiting role in preventing the steel pipe from moving back and forth in the horizontal direction. Hinges 202 are fixedly connected to the rear ends of both sides of the processing table 1. The rear ends of the hinges 202 are fixedly connected to the grippers 203, allowing the grippers 203 to rotate around the hinges 202. The connection point with the processing table 1 is rotated. When it is necessary to fix the vertical steel pipe body 3, the operator rotates the gripper 203 around the hinge 202, bringing it closer to the vertical steel pipe body 3 until the two grippers 203 can encircle the rear end of the vertical steel pipe body 3. The rear ends of the two grippers 203 are fixedly connected to the fixing plates 204. The right side of the right fixing plate 204 has a fastening bolt 205 passing through it. The end of the fastening bolt 205 is threaded into the inside of the left fixing plate 204. After the grippers 203 encircle the vertical steel pipe body 3, the operator tightens the fastening bolt 205. The fastening bolts 205 are threadedly connected to the fixing plates 204. As the fastening bolts 205 are tightened, the two fixing plates 204 move closer together, which in turn drives the two grippers 203 to tighten further, firmly holding the vertical steel pipe body 3 and preventing it from swaying left and right during cutting. Two adjusting screws 206 are threadedly connected to the outside of each gripper 203. Rubber heads 207 are fixedly connected to adjacent ends of the adjusting screws 206. By rotating the adjusting screws 206, due to the threaded connection between the adjusting screws 206 and the grippers 203, the adjusting screws 206 will move axially. The operator can rotate the adjusting screw 206 according to the outer diameter of the vertical steel pipe body 3, so that the rubber head 207 is in close contact with the surface of the vertical steel pipe body 3. The rubber head 207 has a certain elasticity, which can increase the friction with the surface of the steel pipe and avoid damage to the surface of the steel pipe. By adjusting the adjusting screw 206 at different positions, the gripper 203 can be better fitted with the vertical steel pipe body 3, further improving the stability of the fixation. This achieves the stable fixation of the processing table 1 on the vertical steel pipe body 3, enabling it to adapt to vertical steel pipe bodies 3 of various specifications and sizes.

[0043] Reference Figure 1 , Figure 2 and Figure 4A tachometer 14 is fixedly connected to the front side of the processing table 1, and the tachometer 14 is electrically connected to the drive motor 4; O-rings 15 are fixedly connected to the far ends of multiple adjusting screws 206, and the outer surfaces of multiple O-rings 15 are all designed to be non-slip; two U-shaped straps 16 are fixedly connected to the outer surfaces of two electric push rods 11, and multiple U-shaped straps 16 are respectively fixedly connected to the inner sides of two mounting brackets 10; triangular braces 17 are fixedly connected to the bottom rear sides of two mounting brackets 10, and the bottom ends of the two triangular braces 17 are respectively fixedly connected to the top left and right rear ends of the processing table 1; the rear side of the U-shaped plate 201 is designed with an arc shape, and the rear side of the U-shaped plate 201 is attached to the front side of the vertical steel pipe body 3; the outer surfaces of multiple rubber heads 207 are all designed with a smooth shape, and the adjacent sides of multiple rubber heads 207 are all treated with a frosted finish;

[0044] Specifically, the tachometer 14 is electrically connected to the drive motor 4, enabling real-time monitoring of the drive motor 4's operating data during cutting operations. The tachometer converts the drive motor 4's speed information into an electrical signal, feeding it back to the tachometer 14 to prevent equipment damage or reduced cutting accuracy due to overload. The O-ring 15 is fixed to the end of the adjusting screw 206; its anti-slip design facilitates gripping by the operator. When adjusting the fixing mechanism 2, rotating the O-ring 15 drives the adjusting screw 206 to precisely adjust the contact position and pressure between the rubber head 207 and the vertical steel pipe body 3, achieving a quick and effortless tightening operation. The U-shaped strap 16 is installed between the electric push rod 11 and the mounting frame 10, serving a fixing and limiting function. It securely binds the electric push rod 11 to the inside of the mounting frame 10, preventing displacement or shaking during extension and retraction, thus improving the overall reliability of the cutting device. The triangular brace 17 connects to the mounting frame. The mounting bracket 10 and the processing table 1 utilize the stability principle of a triangle to enhance the structural strength of the mounting bracket 10. When the electric push rod 11 is working, it effectively disperses the stress on the mounting bracket 10, preventing it from deforming due to stress and affecting the cutting accuracy. The arc design on the rear side of the U-shaped plate 201 fits the front side of the vertical steel pipe body 3, providing precise positioning support for the steel pipe. During the fixing process, the arc surface fits the outline of the steel pipe, restricting the forward and backward movement of the steel pipe, while also sharing the fixing pressure of the gripper 203. Working together with the gripper 203, it ensures that the steel pipe remains stable during cutting and improves the fixing effect. The smooth outer design of the rubber head 207 prevents scratching the surface of the steel pipe, and the frosted process increases the friction with the steel pipe. By adjusting the screw 206, the rubber head 207 is pushed to fit tightly against the steel pipe, which can not only firmly fix the steel pipe, but also avoid damage to the surface of the steel pipe. At the same time, it can be flexibly adjusted according to different pipe diameters to adapt to the fixing needs of various specifications of vertical steel pipe bodies 3.

[0045] Working principle: The processing table 1 is fixedly installed on the vertical steel pipe body 3 at a suitable position by the fixing mechanism 2. When the drive motor 4 is started, its output end drives the drive rod 5 to rotate. The threaded rope groove 6 on the outside of the drive rod 5 provides the motion trajectory for the cutting rope 7. The cutting rope 7 is placed in the threaded rope groove 6. As the drive rod 5 rotates, the cutting rope 7 generates a motion tendency under the action of the threaded rope groove 6. The guide pulleys 8 on the front left and right sides of the processing table 1, the directional pulleys 9 on the front left and right sides, and the adjusting pulleys 13 connected to the pressure plate 12 at the bottom of the electric push rod 11 on the top left and right side mounting brackets 10 together constitute the guiding and adjusting system of the cutting rope 7. The cutting rope 7 passes through multiple guide pulleys 8, two directional pulleys 9 and two adjusting pulleys 13 in sequence. The guide pulleys 8 ensure that the cutting rope 7 is horizontal. The cutting rope 7 moves stably in the direction of cutting. The height of the pressure plate 12 and the adjusting pulley 13 is adjusted by the electric push rod 11 according to the cutting requirements. When the electric push rod 11 extends or shortens, the adjusting pulley 13 drives the cutting rope 7 to move up and down, thereby adjusting the contact position and cutting depth between the cutting rope 7 and the vertical steel pipe body 3. The pressure plate 12 can sense the tension and pressure changes of the cutting rope 7, realize precise control of the electric push rod 11, and ensure the stability of the cutting process. The rear end of the cutting rope 7 is attached to the rear side of the vertical steel pipe body 3. As the drive rod 5 continues to rotate, the cutting rope 7 moves in a circle around the vertical steel pipe body 3 under the guidance of each pulley. At the same time, the horizontal cutting is realized under the adjustment of the electric push rod 11, thereby completing the intersecting line cutting of the large-diameter vertical steel pipe body 3.

[0046] Furthermore, the U-shaped plate 201 provides a preliminary support and positioning base for the vertical steel pipe body 3. When the vertical steel pipe body 3 is placed on the processing table 1, its front end can fit against the U-shaped plate 201. The shape of the U-shaped plate 201 can adapt to the circular outline of the steel pipe, playing a certain limiting role in the steel pipe and preventing it from moving back and forth in the horizontal direction. Hinges 202 are fixedly connected to the rear ends of both sides of the processing table 1. The rear ends of the hinges 202 are fixedly connected to the grippers 203, allowing the grippers 203 to rotate through the hinges 202. The clamping claw 203 rotates around the hinge 202 when it is necessary to fix the vertical steel pipe body 3. This allows the operator to move the claw 203 closer to the vertical steel pipe body 3 until both claws 203 can encircle the rear end of the vertical steel pipe body 3. A fixing plate 204 is fixedly connected to the rear end of each claw 203. A fastening bolt 205 passes through the right side of the right fixing plate 204, and the end of the fastening bolt 205 is threaded into the inside of the left fixing plate 204. When the claws 203 encircle the vertical steel pipe body... After step 3, the operator tightens the fastening bolts 205. Due to the threaded connection between the fastening bolts 205 and the fixing plates 204, as the fastening bolts 205 are tightened, the two fixing plates 204 move closer together, which in turn drives the two grippers 203 to tighten further, firmly holding the vertical steel pipe body 3 and preventing it from swaying left and right during the cutting process. Two adjusting screws 206 are threadedly connected to the outside of each of the two grippers 203. Each adjacent end of the adjusting screw 206 is fixedly connected to a rubber head 207. By rotating the adjusting screw 206... 6. Due to the threaded connection between the adjusting screw 206 and the gripper 203, the adjusting screw 206 will move axially. The operator can rotate the adjusting screw 206 according to the outer diameter of the vertical steel pipe body 3 to make the rubber head 207 in close contact with the surface of the vertical steel pipe body 3. The rubber head 207 has a certain elasticity, which can increase the friction with the surface of the steel pipe and avoid damage to the surface of the steel pipe. By adjusting the adjusting screw 206 at different positions, the gripper 203 can be better fitted to the vertical steel pipe body 3.
