DETAILED DESCRIPTION

[0035] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent. Specific implementation method 1 like Figure 1 and Figure 2As shown, this specific embodiment provides a pipe feeding device, including a base 505, a fixed platform 300, a mobile platform 200 and at least two feeding vehicles 100, the length directions of the fixed platform 300, the mobile platform 200 and the base 505 are consistent with the length direction of the pipe raw material. In this specific embodiment, two feeding vehicles 100 are provided, and a plurality of feeding brackets 504 are provided on the base 505 along its own length direction; specifically, the fixed platform 300 is set on the ground on the feeding side of the base 505 by anchor bolts, and the mobile platform 200 is located on the fixed platform 300 has a loading end and its upper surface is flush with the upper surface of the fixed platform 300, the mobile platform 200 can move relative to the fixed platform 300, the moving direction of the mobile platform 200 is parallel to the width direction of the base 505, and in this specific embodiment, the mobile platform 200 is movably set on the ground; the loading cart 100 can reciprocate on the mobile platform 200 and the fixed platform 300, and a plurality of the loading carts 100 can be arranged on the mobile platform 200 along the moving direction of the mobile platform 200, and the loading cart 100 is connected with a loading assembly.

[0037] By setting up a mobile platform 200, a fixed platform 300 and at least two loading carts 100, this specific embodiment can move the loading cart 100 carrying the remaining profile raw materials out of the loading position as a whole when it is necessary to unload the remaining multiple pipes, and move the loading cart 100 carrying the new pipe raw materials as a whole to the loading position to continue loading. Compared with the prior art that adopts the form of hoisting to unload the remaining pipe materials, it can greatly shorten the time for unloading the remaining pipe materials, shorten the waiting time of the loading device, thereby avoiding the pipe cutting machine from stopping, and greatly reducing the adverse effects of the loading and unloading of raw materials on production efficiency.

[0038] like Figures 3 to 6As shown, in other embodiments, the loading vehicle 100 can actually be equipped with its own driving system. However, in this specific embodiment, out of comprehensive consideration of various factors such as overall structural optimization and reducing deadweight to improve operating efficiency, the loading vehicle 100 adopts a passive drive method. A material pulling chain transmission assembly and a material pulling motor 303 are specially provided on the fixed platform 300; wherein the material pulling motor 303, as a power source, can drive the material pulling chain transmission assembly to rotate. Specifically, the material pulling chain transmission assembly includes a material pulling chain 315, a driving sprocket and a passive sprocket. The driving sprocket and the passive sprocket are rotatably arranged at the two ends of the fixed platform 300 with the aid of bearings. When the material pulling motor 303 is working, it will drive the driving sprocket to start rotating through the transmission belt, thereby driving the coordinated operation of the entire material pulling chain transmission assembly; a hook seat 312 is also provided on the material pulling chain 315, and a swingable hanging ring 314 is realized on the hook seat 312 through a pin shaft. This The hanging ring 314 has the function of being mutually engaged with the hook on the feeding trolley 100, and a hook cylinder 313 is installed between the hanging ring 314 and the hook seat 312. When the hook cylinder 313 extends outward, the hanging ring 314 will rotate downward under its action, so as to smoothly engage with the hook. In this way, the pulling chain transmission assembly can pull the feeding trolley 100 to move, and when the hook cylinder 313 retracts inward, the hanging ring 314 will rotate upward, thereby disengaging from the hook, releasing the connection between the two. connection relationship; in order to ensure the stability and accuracy of the loading trolley 100 during movement, the loading trolley 100 is also equipped with rollers 105; accordingly, a guide rail group 302 is provided on the fixed platform 300, and the guide rail group 302 consists of two guide rails, and the rollers 105 can move smoothly along the two guide rails. This design can effectively avoid collisions between the loading trolley 100 and the loading trolley 100 during movement, thereby ensuring the safety and smoothness of the entire loading process, so that production operations can continue in an orderly manner.

[0039] like Figures 3 to 5As shown, the precise positioning of the loading trolley 100 plays a vital role in the stability and efficiency of the entire production process; in the actual working environment, the loading trolley 100 is often disturbed by various vibration factors, and these vibrations are very likely to cause the loading trolley 100 to be displaced, which will inevitably have a serious negative impact on the accuracy of loading and the entire production rhythm; therefore, in this specific embodiment, a limit plate 320 is set at one end of the fixed platform 300 away from the mobile platform 200, and at the other end of the fixed platform 300, a positioning plate 324 is rotatably provided to avoid interference, specifically, the positioning plate 324 is connected to the piston rod of the positioning cylinder by a hinge, and the positioning cylinder is rotatably arranged on the fixed platform 300 by a hinge seat; after such arrangement, the limit plate 320 and the positioning plate 324 can respectively abut against the two ends of the loading trolley 100, thereby effectively limiting the position of the loading trolley 100 When the loading trolley 100 moves, the positioning plate 324 will remain in a horizontal or nearly horizontal state under the precise control of the positioning cylinder. In this state, the positioning plate 324 will not interfere with the loading trolley 100. After a period of movement, the loading trolley 100 gradually approaches and finally contacts the limit plate 320. At this time, the proximity switch installed on the limit plate 320 will quickly send a signal, and the positioning cylinder will extend. Under the push of the positioning cylinder, the positioning plate 324 begins to rotate upward, and the positioning plate 324 gradually approaches the end of the loading trolley 100 until it finally closely abuts against the end of the loading trolley 100 and maintains a stable contact state, thereby realizing precise limiting of the loading trolley 100, so that the loading trolley 100 can still be firmly in the predetermined position when affected by interference factors such as vibration, providing reliable guarantee for subsequent loading operations and greatly improving the stability of the production process.

[0040] like Figure 1 and Figure 3 As shown, in this specific embodiment, the mobile platform 200 is set on the ground through a slide rail, the bottom surface of the mobile platform 200 is connected to the piston rod of the driving cylinder, the cylinder body of the driving cylinder is set on the ground, and two groups of guide rail groups 302 are arranged on the mobile platform 200; preferably, in order to ensure that the guide rail groups of the mobile platform 200 and the fixed platform 300 can be aligned, a positioning hole is arranged at the end of the mobile platform 200, and a positioning pin 311 is telescopically arranged at the end of the fixed platform 300 through a cylinder, and the positioning pin 311 can be extended into the positioning hole at the end of the mobile platform 200, and the end of the positioning pin 311 is in a conical structure. For the convenience of control, a proximity sensor is arranged in the positioning hole, and the proximity sensor can respond to the positioning pin 311.

[0041] like Figure 6 and Figure 7As shown, in order to ensure that the pipes can be loaded one by one and avoid stacking of pipes, in this specific embodiment, the loading assembly includes a load-bearing frame and a lifting drive assembly, and the load-bearing frame includes a support rod 104 and a lifting rod 106 that are relatively arranged along the width direction of the loading vehicle 100, and the top of the support rod 104 and the top of the lifting rod 106 are connected by a load-bearing cloth belt 103, and the lifting drive assembly can drive the lifting rod 106 to rise and fall; by driving one end of the load-bearing cloth belt 103 to rise by the lifting rod 106, multiple pipes can be made to slide onto the loading bracket 504 of the base 505, and by controlling the lifting drive assembly, the inclination angle of the multiple pipes as a whole can be effectively controlled to facilitate loading one by one.

[0042] like Figures 8 to 9 As shown, the lifting drive assembly can adopt an electric reel and be arranged on the loading cart 100. In order to further simplify the structure of the loading cart 100, reduce the load, and reduce the volume of the loading cart 100, thereby reducing the footprint of the mobile platform 200, in this specific embodiment, the loading assembly does not move with the loading cart 100. The lifting drive assembly includes a support frame 400, one side of the support frame 400 is set on the ground by anchor bolts, and the other side is connected to the fixed platform 300 by bolts. A loading chain transmission assembly and a loading motor 408 are arranged on the support frame 400. The loading chain transmission assembly includes a loading chain 406, a driving sprocket, a driven sprocket and a guide sprocket. The loading motor 408 drives the active sprocket to rotate through the transmission belt, and a lifting plate 402 is provided on the feeding chain 406, and a slider is provided on the back of the lifting plate 402, and the slider can move up and down along the slide groove on the support frame 400, and a clamping groove is provided on the top of the lifting plate 402. The lifting plate 402 can be clamped with the clamping shaft 102 on one side of the top of the lifting rod 106, and the lifting plate 402 can drive the lifting rod 106 to rise and fall. The lifting rod 106 includes two sections of cylindrical pipes that are sleeved together and can move axially. Preferably, in order to reduce friction, a support wheel 107 is rotatably provided on the top of the lifting rod 106, and the support wheel 107 moves along the support frame 400.

[0043] like Figures 6 to 8 As shown, preferably, in order to ensure the stability of loading of the loading assembly, four support rods 104 and four lifting rods 106 are respectively provided, and four lifting plates 402 are also provided accordingly. In order to ensure that the four lifting plates 402 can move synchronously, one loading motor 408 is provided, and four groups of loading chain transmission assemblies are provided. Specifically, the loading motor 408 drives the transmission shaft 412 to rotate through the transmission belt, and four driving sprockets are provided on the transmission shaft 412. The driven sprocket and the guide sprocket are rotatably provided on the support frame 400 through bearings; accordingly, four loading brackets 504 are also provided.

[0044] like Fig.10 As shown, in order to realize fully automatic loading, the present embodiment also includes a moving frame 500, on which a shift fork assembly is provided, and four shift fork assemblies are provided. The moving frame 500 straddles the base 505 and moves along the width direction of the base 505. In the present embodiment, the moving frame 500 includes two supports 503, and a crossbeam is provided between the two supports 503. The shift fork assembly is provided on the crossbeam. The supports 503 can reciprocate along the width direction of the base 505 through a motor and a gear rack structure, and the shift fork assembly can move along the width direction of the base 505 with the moving frame 500. In the present embodiment, the shift fork assembly includes a shift fork 501, and the shift fork 501 is connected to a lifting shaft, and a rack is provided on the lifting shaft, and the rack is meshed with a corresponding gear. The four gears are coaxially arranged on the same rotating shaft 502, and one of the shift fork assemblies is connected to a material-discharging motor 507, and the material-discharging motor 507 drives the rotating shaft 502 to rotate, thereby driving the four lifting shafts to rise and fall synchronously, so as to realize When the fork assembly is working, it first moves to the feeding side of the base 505 and is a distance of one pipe diameter or width from the feeding side. When one end of the carrying cloth belt 103 rises to a certain height, one of the pipes slides to the side of the fork 501. A proximity sensor is provided on one side of the fork 501. The height of the proximity sensor from the top surface of the feeding bracket 504 is between one and two times the height or diameter of the pipe. When the proximity sensor sends a signal, it means that there are more than one pipe and the side of the fork 501. The fork 501 is in contact with the wall. At this time, the fork 501 rises up by a distance of the height or diameter of the pipe, and then continues to move toward the fixed platform 300 by a distance of the width or diameter of the pipe driven by the mobile frame 500, pushing the excess pipe back into the carrying cloth belt 103, further ensuring that the pipe is fed one by one. Then, the fork 501 descends, and the mobile frame 500 moves in the opposite direction, driving the pipe to move on the base 505 until it moves to the feeding side of the base 505, and is transported by the feeding mechanism of the pipe cutting machine for cutting.

[0045] In this specific embodiment, the material pulling motor 303, the material loading motor 408, and the material shifting motor 507 are all servo motors, which facilitates accurate control. Specific implementation method 2 This specific embodiment provides a method for loading and unloading pipes, using the pipe loading device of the specific embodiment 1, including the following steps: S01: Pipes are hoisted in bundles onto corresponding loading vehicles 100; S02: After the mobile platform 200 moves a set distance driven by the driving cylinder, the positioning pin 311 extends into the positioning hole, the guide rail group on the mobile platform 200 is aligned with the guide rail group on the fixed platform 300, and the feeding motor 408 is activated to drive the hanging ring 314 to approach the mobile platform 200. After moving the set distance, the hook cylinder 313 extends to drive the hanging ring 314 to rotate toward the hook at the end of the upper feed cart 100 until it is engaged. The feeding motor 408 rotates in the opposite direction to drive the feeding cart 100 to move from the mobile platform 200 to the fixed platform 300. When it moves into place, the positioning cylinder is activated so that the feeding cart 100 is clamped by the limit plate 320 and the positioning plate 324. S03: After the fork assembly moves to the set position on the feeding side of the base 505, the feeding motor 408 drives the lifting plate 402 to lift, and lifts the lifting rod 106 to the corresponding position. One of the pipe materials rolls onto the feeding bracket 504 and is blocked by the fork. The lifting plate 402 descends, and the carrying cloth belt 103 returns to its original shape. S04: The fork assembly moves the first pipe material abutting against the outer side surface thereof to the conveying end of the loading bracket 504; S05: Repeat S03 to S04 until a set amount of pipe material is delivered, and the height of the lifting rod 106 increases each time it is raised; S06: When the remaining pipe raw materials need to be unloaded, the positioning plate 324 is flipped to a horizontal state, the hook cylinder 313 extends to drive the hanging ring 314 to rotate toward the hook at the end of the upper feed trolley 100 until it is engaged, the feeding motor 408 rotates, and the feeding trolley 100 is pushed from the fixed platform 300 to the mobile platform 200 by the push of the hook seat 312, and the positioning pin 311 retracts; S07: The mobile platform 200 moves under the drive of the driving cylinder, and another set of guide rails is aligned with the guide rails on the fixed platform 300. The positioning pin 311 extends out, and another loading car 100 carrying new pipe raw materials is moved from the mobile platform 200 to the fixed platform 300. S03 to S05 are repeated until a set amount of new pipe raw materials are delivered, and the remaining pipe raw materials are hoisted and unloaded.

[0047] From the above specific implementations, it can be seen that the present invention has the following beneficial effects: 1. By setting up a mobile platform 200, a fixed platform 300 and at least two loading carts 100, when necessary, the loading cart 100 carrying the remaining profile raw materials can be moved out of the loading position as a whole, and the loading cart 100 carrying the new pipe raw materials can be moved as a whole to the loading position to continue loading, which greatly shortens the time for loading the profile raw materials, shortens the waiting time of the loading device, avoids the pipe cutting machine from stopping, and greatly reduces the adverse effects of the loading and unloading of raw materials on the production efficiency; by setting the positioning pin 311, the mobile platform 200 and the fixed platform 300 can be aligned to avoid collision of the loading cart 100 during the movement; 2. By setting the limit plate 320 and the positioning plate 324, the position of the loading vehicle 100 can be locked after it moves into position, so as to avoid the loading vehicle 100 from moving under the action of external force, causing the loading position deviation and interference collision; 3. The guide rail group is set to limit the loading car to 100 degrees to avoid deviation; the loading cloth belt is formed into a slope by lifting, which is convenient for the pipe raw materials to rise, and at the same time, the force condition of the loading component is optimized to extend the service life; 4. By setting the lifting drive assembly on the ground, the load of the loading vehicle 100 is reduced, making it easier to drive.

[0048] This feeding device has the advantages of high efficiency, stability, safety and durability, and can bring significant production efficiency improvements to the enterprise.
