Abstract
Description
Technical Field
[0001] The utility model relates to a long tube conveying and arranging mechanism, in particular to a long tube conveying and arranging mechanism for a boiler tube panel intelligent production line. Background Art
[0002] The serpentine tube panels of large power plant boilers are typically composed of multiple tubes combined to form a screen-like heating surface. In actual production, short tubes, ranging from 1 to 12 meters, are typically welded onto automatic welding machines into long tubes, typically 40 to 100 meters long. After passing flaw detection, the long tubes are then placed in a temporary storage area. From there, they are transported to a tube bending machine, which bends them into the desired shape. Because flaw detection takes a short time for long tubes, while welding takes a long time, the process typically involves one flaw detection machine corresponding to multiple welding machines. This results in a material transfer and buffering process after welding, where the material is often moved by rolling the tubes on a support rack in the buffer area, leveraging their weight to move them along an inclined surface at a predetermined angle.
[0003] Due to the long length of the long tubes, they have poor rigidity and a certain amount of curvature along their length. When multiple long tubes are rolled on a supporting rack, jamming may occur. For example, when long tube one is perpendicular to the rack, the adjacent long tube two, with one end in contact with the end of long tube one and the other end away from long tube one, forms a certain angle between the two long tubes, preventing long tube two from entering the next area. Currently, most industry solutions rely on manual intervention, but this method is time-consuming and labor-intensive, and production automation is impossible, which hinders production efficiency. Summary of the Invention
[0004] The purpose of the utility model is to address the above-mentioned deficiencies in the prior art and provide a long tube conveying and sorting mechanism, which can prevent the long tube from deformation and jamming when being conveyed in the buffer area, thereby realizing the automation of the production line and improving production efficiency.
[0005] In order to achieve the above-mentioned purpose, the utility model provides a long tube conveying and sorting mechanism, including a connected motor and reducer, a material conveying mechanism, and a material sensing mechanism; the characteristics are: the material conveying mechanism includes two or more conveying units arranged at intervals, and several supporting material racks arranged between two adjacent conveying units, each conveying unit includes a conveying material rack, a conveying sprocket chain mechanism and a transmission sprocket chain mechanism arranged on the conveying material rack, and the driving sprocket of the conveying sprocket chain mechanism is coaxially connected with the driven sprocket of the transmission sprocket chain mechanism; all conveying material racks and supporting material racks are arranged in parallel, and the motor and reducer are arranged between adjacent conveying material racks. Between the material rack and the supporting material rack, the reducer is connected to the driving sprocket of each transmission sprocket chain mechanism through the transmission shafts on both sides; the material sensing mechanism includes a sensing support fixedly connected to the chain of each conveying sprocket chain mechanism, and a mounting hole provided in each sensing support.

A proximity switch is provided on the sensing support to cooperate with the rear end of each sensing column.
[0006] When in use, the long tube is placed on the conveying rack and the supporting rack at the same time, and the chain of the conveying sprocket chain mechanism is driven to move by the motor, reducer, transmission shaft, and transmission sprocket chain mechanism, so that each induction support and induction column push the long tube forward to the front end of the rack and position it in multiple points in the direction perpendicular to the axis of the long tube, which can prevent the long tube from deformation and jamming when being conveyed in the buffer area; when the long tube is positioned and no longer moves, the front end of the induction column is subjected to pressure after contacting the long tube, and the spring can be compressed to make the rear end of the induction column close to the proximity switch to realize signal collection, indicating that the long tube has been conveyed and sorted in place, thereby realizing the automation of the production line and improving production efficiency;
[0007] As a further improvement of the present invention, the conveying rack and the supporting rack are both inclined with the front lower and the back higher, so as to facilitate the movement of the long pipe by rolling on a slope at a certain angle using the pipe's gravity;
[0008] As a further improvement of the present invention, the front ends of the conveying rack and the supporting rack are fixed with a stopper, which can realize the accurate positioning of the long tube after it is conveyed into place;
[0009] As a further improvement of the present invention, the upper ends of the support racks are fixedly connected with two parallel round steel bars, which can reduce the contact resistance and facilitate the transportation of long pipes.
[0010] As a further improvement of the present invention, each induction support is fixedly connected to the chain of each conveying sprocket chain mechanism through two pins, which facilitates the connection of the induction support;
[0011] As a further improvement of the present invention, the nut is fixedly connected to the rear section of the mounting hole by an external thread; this facilitates the installation of the nut and the adjustment of the position of the sensing column to ensure the accuracy of signal acquisition;

Sensing columns 13 are slidably provided in the mounting holes. The front end of the sensing column 13 is located in front of the sensing support 12, and a nut 15 is fixedly connected to the rear section of the mounting hole through an external thread. The rear section of the sensing column 13 is slidably provided in the inner hole of the nut 15. A step 14 is fixedly provided on the outer circle of the sensing column 13 in the mounting hole, and a spring 16 is provided on the outer sleeve of the sensing column 13 between the nut 15 and the step 14.

The chains 19 of the conveying sprocket chain mechanisms 6 are driven to move through the reducer 2, the transmission shafts 10 on both sides, and the transmission sprocket chain mechanisms 7, so that each sensing support 12 and the sensing column 13 push the long tube 18 forward horizontally at multiple points (two of which are located at the two ends of the long tube) in the direction perpendicular to the axis of the long tube to the stopper 8 at the front end of the rack and position it, which can ensure that the long tube 19 is prevented from deformation and jamming when being transported in the buffer area, and each time the long tube is transported, the two racks can be vertically connected; when the long tube is positioned and no longer moves, the front end of the sensing column 13 contacts the long tube 19 and is subjected to pressure, and the compressible spring 16 makes the rear end of the sensing column close to the proximity switch 17 to realize signal collection, indicating that the long tube has been transported and sorted in place. The sensing column 13 not only pushes the long tube 19 forward, but also cooperates with the proximity switch 17 to realize signal collection, thereby realizing the automation of the production line and improving production efficiency;
[0022] The inclined conveying rack 5 and the supporting rack 4 facilitate the movement of the long tube by rolling on the inclined surface at a certain angle using the weight of the tube; the stopper 8 can realize the accurate positioning of the long tube after it is transported into place;
