Description

Technical Field

[0001] This utility model relates to the field of steel pipe transfer technology, and in particular to a large steel pipe transfer device. Background Technology

[0002] Large steel pipes refer to steel pipes with large outer diameter, wall thickness, or length. They generally have high strength and load-bearing capacity. They are made of various materials, including carbon steel, alloy steel, and stainless steel, and can be selected according to different application scenarios and performance requirements. Large steel pipes are often used in large-scale construction projects (such as bridges and high-rise building structures), petrochemicals (such as oil and gas pipelines and reaction tower pipelines), and power (such as power plant boiler pipelines).

[0003] Currently, most large steel pipes are transported by hoisting after processing due to their large size. This operation is cumbersome, increases production costs, and is not conducive to mass production in factories. Therefore, the operation needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the existing technology, most large steel pipes are often transported by hoisting after processing due to their large size, which is cumbersome, increases production costs, and is not conducive to mass production in factories. Therefore, a large steel pipe transport device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a large steel pipe transfer device, comprising a base plate, a transfer mechanism provided on the upper surface of the base plate, the transfer mechanism comprising a first stabilizing plate, the first stabilizing plate being fixedly connected to the upper surface of the base plate, a first support seat being fixedly connected to the upper surface of the first stabilizing plate, a first lever being rotatably connected to the inner wall of the first support seat, a second stabilizing plate being fixedly connected to the upper surface of the base plate, a second support seat being fixedly connected to the upper surface of the second stabilizing plate, a second lever being rotatably connected to the inner wall of the second support seat, and a support rod being fixedly connected to the upper surface of the base plate, the upper end of the support rod being rotatably connected to... With a guide rod attached, after processing is completed, the piston rod of the first cylinder is extended, driving the first lever to rotate and lift the steel pipe, allowing it to fall smoothly onto the second lever. Then, the second cylinder is retracted, and the second lever rotates towards the base plate. Simultaneously, the first cylinder pushes the first lever back to its original position, and the steel pipe slides smoothly along the second lever to the guide rod. During the transfer process, the bending design of the first and second levers closely conforms to the shape of the steel pipe, effectively preventing the steel pipe from slipping and providing stable support and guidance. The guide rod further guides the steel pipe to slide precisely to the next production line, significantly reducing shaking and deviation during the transfer process, ensuring the stability of the transfer, and reducing the risk of damage to the steel pipe due to unstable transfer.

[0006] Preferably, a first protrusion is fixedly connected to the upper surface of the first stabilizing plate, and a first cylinder is rotatably connected to the inner wall of the first protrusion. The driving end of the first cylinder is inserted into the first lever and rotatably connected to the inner wall of the first lever, which facilitates the normal use of the equipment.

[0007] Preferably, a second protrusion is fixedly connected to the upper surface of the second stabilizing plate, and a second cylinder is rotatably connected to the inner wall of the second protrusion. The driving end of the second cylinder is inserted into the second lever and rotatably connected to the inner wall of the second lever.

[0008] Preferably, the longitudinal sections of both the first lever and the second lever are bent to facilitate the transfer of the steel pipe.

[0009] Preferably, there are three support rods and three guide rods, which are arranged at equal intervals. A reinforcing rod is fixedly connected to the lower surface of each support rod, and a third cylinder is fixedly connected to the upper surface of the base plate. A protective frame is fixedly connected to the drive end of the third cylinder, and a support roller is rotatably connected to the inner wall of the protective frame. The support rod rests on the support roller. The height of the protective frame and the support roller is adjusted by controlling the third cylinder according to the feeding speed, thus flexibly changing the tilt angle of the guide rod. When facing the next production line with a faster processing speed, the tilt angle of the guide rod is appropriately increased to facilitate the rapid sliding of the steel pipe. If the next production line is performing fine operations and requires a slower feeding speed, the tilt angle of the guide rod is decreased. The feeding speed and path of the steel pipe can be precisely controlled according to the rhythm and needs of different production lines, greatly improving the coordination and smoothness of the entire production process and avoiding production stagnation or chaos caused by improper transfer speed.

[0010] Preferably, a support mechanism is provided on the upper surface of the base plate. The support mechanism includes a mounting frame, which is fixedly connected to the upper surface of the base plate. A positioning block is fixedly connected to one side of the mounting frame, and a first mounting seat is mounted on the upper surface of the positioning block. A drive wheel is rotatably connected to the inner wall of the first mounting seat, and a drive motor is fixedly connected to one side of the first mounting seat. The drive end of the drive motor passes through the first mounting seat and is fixedly connected to the axis of the drive wheel. Two symmetrically arranged support sliders are slidably connected to the inner wall of the mounting frame, and a second mounting seat is mounted on the upper surface of the support sliders. The inner wall of the second mounting seat is rotatably connected to... The device features guide wheels, and a bidirectional screw is rotatably connected to the inner wall of the mounting bracket. The bidirectional screw is threadedly connected to the inner wall of the support slider. Before steel pipe processing, the bidirectional screw is driven by rotating the adjustment handle, causing the two support sliders, the second mounting base, and the guide wheels to move in opposite directions. This allows for precise adjustment of the guide wheel spacing, enabling the device to easily adapt to steel pipes of various diameters. Whether it is a small-diameter steel pipe used for precision instruments or a large-diameter steel pipe used in industrial infrastructure, it can be stably placed on the guide wheels, providing reliable support for subsequent processing steps. Compared to traditional single-specification support equipment, it eliminates the need for frequent equipment replacement, greatly saving time and costs and significantly improving production efficiency.

[0011] Preferably, the inner wall of the mounting base is rotatably connected to an adjustment handle, and the adjustment handle is fixedly connected to the axis of the bidirectional screw. Rotating the adjustment handle can drive the bidirectional screw to rotate, thereby adjusting the rotation of the support slider, the second mounting base and the guide wheel.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, after processing is completed, the piston rod of the first cylinder is extended, driving the first lever to rotate and lift the steel pipe, allowing it to fall smoothly onto the second lever. Then, the second cylinder is retracted, and the second lever rotates towards the base plate. Simultaneously, the first cylinder pushes the first lever back to its original position, and the steel pipe slides smoothly along the second lever to the guide rod. During the transfer process, the bending design of the first and second levers closely conforms to the shape of the steel pipe, effectively preventing the steel pipe from slipping and providing stable support and guidance. The guide rod further guides the steel pipe to slide precisely to the next production line, significantly reducing shaking and deviation during the transfer process, ensuring transfer stability, and reducing the risk of damage to the steel pipe due to unstable transfer.

[0014] In this invention, the height of the protective frame and the support rollers is adjusted by controlling the third cylinder according to the feeding speed, thereby flexibly changing the tilt angle of the guide rod. When facing the next production line with a faster processing speed, the tilt angle of the guide rod is appropriately increased to facilitate the rapid sliding of the steel pipe. If the next production line is performing fine operations and requires a slower feeding speed, the tilt angle of the guide rod is reduced. The feeding speed and path of the steel pipe can be precisely controlled according to the rhythm and needs of different production lines, greatly improving the coordination and smoothness of the entire production process and avoiding production stagnation or chaos caused by improper transfer speed.

[0015] In this invention, before steel pipe processing, the bidirectional screw is driven by rotating the adjustment handle, causing the two support sliders, the second mounting base, and the guide wheel to move in opposite directions. This achieves precise adjustment of the guide wheel spacing, enabling the device to easily adapt to steel pipes of various diameters. Whether it is a small-diameter steel pipe used for precision instruments or a large-diameter steel pipe used in industrial infrastructure, it can be stably placed on the guide wheel, providing reliable support for subsequent processing steps. Compared with traditional single-specification support equipment, there is no need to frequently change equipment, which greatly saves time and costs and significantly improves production efficiency.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a large steel pipe transfer device, including a base plate 1, a transfer mechanism 2 provided on the upper surface of the base plate 1, the transfer mechanism 2 including a first stabilizing plate 21, the first stabilizing plate 21 being fixedly connected to the upper surface of the base plate 1, a first support seat 26 being fixedly connected to the upper surface of the first stabilizing plate 21, a first lever 22 being rotatably connected to the inner wall of the first support seat 26, a second stabilizing plate 25 being fixedly connected to the upper surface of the base plate 1, a second support seat 27 being fixedly connected to the upper surface of the second stabilizing plate 25, a second lever 28 being rotatably connected to the inner wall of the second support seat 27, a support rod 211 being fixedly connected to the upper surface of the base plate 1, and a guide rod 212 being rotatably connected to the upper end of the support rod 211, completing the transfer... After the initial operation, the piston rod of the first cylinder 24 extends, causing the first lever 22 to rotate and lift the steel pipe, allowing it to fall smoothly onto the second lever 28. Then, the second cylinder 210 retracts, causing the second lever 28 to rotate towards the base plate 1. Simultaneously, the first cylinder 24 pushes the first lever 22 back to its original position, and the steel pipe slides smoothly along the second lever 28 to the guide rod 212. During the transfer process, the bending design of the first and second levers 28 closely conforms to the shape of the steel pipe, effectively preventing it from slipping and providing stable support and guidance. The guide rod 212 further guides the steel pipe to slide precisely to the next production line, significantly reducing swaying and deviation during the transfer process, ensuring the stability of the transfer, and reducing the risk of damage to the steel pipe due to unstable transfer.

[0024] In this embodiment: a first protrusion 23 is fixedly connected to the upper surface of the first stabilizing plate 21, and a first cylinder 24 is rotatably connected to the inner wall of the first protrusion 23. The driving end of the first cylinder 24 is inserted into the first lever 22 and rotatably connected to the inner wall of the first lever 22, which facilitates the normal use of the equipment.

[0025] Specifically, a second protrusion 29 is fixedly connected to the upper surface of the second stabilizing plate 25, and a second cylinder 210 is rotatably connected to the inner wall of the second protrusion 29. The driving end of the second cylinder 210 is inserted into the second lever 28 and rotatably connected to the inner wall of the second lever 28.

[0026] Specifically, the longitudinal sections of both the first lever 22 and the second lever 28 are bent to facilitate the transfer of steel pipes.

[0027] Specifically, there are three support rods 211 and three guide rods 212, which are arranged at equal intervals. A reinforcing rod 213 is fixedly connected to the lower surface of the support rod 211, and a third cylinder 214 is fixedly connected to the upper surface of the base plate 1. A protective frame 215 is fixedly connected to the drive end of the third cylinder 214, and a support roller 216 is rotatably connected to the inner wall of the protective frame 215. The support rod 211 rests on the support roller 216. The protective frame 215 is adjusted according to the feeding speed by controlling the third cylinder 214. The height of the frame 215 and the support roller 216 can be adjusted to flexibly change the inclination angle of the guide rod 212. When facing the next production line with a faster processing speed, the inclination angle of the guide rod 212 can be appropriately increased to make the steel pipe slide down quickly. If the next production line is performing fine operation and the feeding speed is slower, the inclination angle of the guide rod 212 can be reduced. The feeding speed and path of the steel pipe can be precisely controlled according to the rhythm and needs of different production lines, which greatly improves the coordination and smoothness of the entire production process and avoids production stagnation or chaos caused by improper transfer speed.

[0028] In this embodiment: A support mechanism 3 is provided on the upper surface of the base plate 1. The support mechanism 3 includes a mounting frame 31, which is fixedly connected to the upper surface of the base plate 1. A positioning block 32 is fixedly connected to one side of the mounting frame 31. A first mounting seat 33 is mounted on the upper surface of the positioning block 32. A drive wheel 34 is rotatably connected to the inner wall of the first mounting seat 33. A drive motor 35 is fixedly connected to one side of the first mounting seat 33. The drive end of the drive motor 35 passes through the first mounting seat 33 and is fixedly connected to the axis of the drive wheel 34. Two symmetrically arranged support sliders 38 are slidably connected to the inner wall of the mounting frame 31. A second mounting seat 36 is mounted on the upper surface of the support sliders 38. A second mounting seat 36 is rotatably connected to the inner wall of the second mounting seat 36. The guide wheel 37 and the inner wall of the mounting bracket 31 are rotatably connected to a bidirectional screw 39, which is threadedly connected to the inner wall of the support slider 38. Before the steel pipe is processed, the bidirectional screw 39 is driven by rotating the adjustment handle 310, which causes the two support sliders 38, the second mounting seat 36 and the guide wheel 37 to move in opposite directions, so as to achieve precise adjustment of the spacing between the guide wheels 37. This allows the device to easily adapt to steel pipes of various diameters. Whether it is a small-diameter steel pipe used for precision instruments or a large-diameter steel pipe used in industrial infrastructure, it can be stably placed on the guide wheel 37 to provide reliable support for subsequent processing. Compared with traditional single-specification support equipment, there is no need to frequently change equipment, which greatly saves time and costs and significantly improves production efficiency.

[0029] Specifically, an adjustment handle 310 is rotatably connected to the inner wall of the mounting base, and the adjustment handle 310 is fixedly connected to the axis of the bidirectional screw 39. Rotating the adjustment handle 310 can drive the bidirectional screw 39 to rotate, thereby adjusting the rotation of the support slider 38, the second mounting base 36 and the guide wheel 37.

[0030] Working principle: Before processing the steel pipe, rotating the adjusting handle 310 drives the bidirectional screw 39 to rotate, which in turn drives the two support sliders 38, the second mounting base 36, and the guide wheel 37 to move in opposite directions, thereby adjusting the distance between the two guide wheels 37. Then, the steel pipe is placed on the guide wheel 37, and the drive motor 35 is turned on. The drive motor 35 drives the drive wheel 34 to rotate, which in turn drives the steel pipe to rotate. During this process, welding or cleaning operations can be performed on the steel pipe.

[0031] After the operation is completed, the piston rod of the first cylinder 24 can be extended, and then the first lever 22 rotates, lifting the steel pipe. The steel pipe then falls onto the second lever 28. At the same time, the piston rod of the second cylinder 210 is retracted, and the second lever 28 rotates towards the base plate 1. Simultaneously, the first cylinder 24 pushes the first lever 22. After the first lever 22 returns to its original position, the steel pipe slides along the second lever 28 onto the guide rod 212. The tilt angle of the guide rod 212 can be controlled according to the feeding speed. Only the height of the protective frame 215 and the support roller 216 needs to be adjusted by controlling the third cylinder 214. Then the guide rod 212 rotates, and the steel pipe slides down the guide rod 212 to the next production line.
