Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-8 The present invention provides two technical solutions, specifically including the following embodiments: Example 1: In this embodiment of the invention, an automatic roller changing device for an automated steel pipe production line includes a body 1. Two concave conveyor frames 3 are slidably connected to the top surface of the body 1. The concave conveyor frames 3 carry roller assembly bodies 4 inside. The two concave conveyor frames 3 are respectively used to convey used roller assembly bodies 4 and new roller assembly bodies 4. In this embodiment of the invention, a plurality of transmission end heads 401 are installed at the end of the roller body 4. The transmission end heads 401 are used to be assembled to the drive end of the production line. The drive end is the drive equipment inside the steel pipe production line. The roller body 4 is an existing device used to be assembled to the inside of the steel pipe production line to realize the rolling and forming operation of the steel pipe. It will not be described in detail here. In this embodiment of the invention, a drive assembly is provided between the interior of the machine body 1 and the two concave conveyor frames 3, which is used to drive the two concave conveyor frames 3 to slide along the top of the machine body 1, push the corresponding concave conveyor frames 3 to the position of the assembly roller group body 4 on the production line, and at the same time, the drive assembly is used to adjust the height of the concave conveyor frames 3, so as to fine-tune the height of the roller group body 4. In this embodiment of the invention, the interior of each of the two concave conveyor frames 3 is provided with a bearing drive frame 9. The bearing drive frame 9 is used to support the roller assembly body 4. Multiple conveyor wheel assemblies 10 are rotatably connected to both sides of the bearing drive frame 9 to drive the bearing drive frame 9 into the production line and realize the automatic replacement operation of the roller assembly body 4. In this embodiment of the invention, when it is necessary to replace the roller assembly body 4 inside the steel pipe production line, firstly, the drive assembly is operated to drive two concave conveyor frames 3 to slide along the top of the machine body 1, so that one of the concave conveyor frames 3 is aligned with the roller assembly body 4 of the steel pipe production line. Then, the bearing drive frame 9 enters the production line. As the roller assembly body 4 is disassembled, the bearing drive frame 9 is reset, driving the used roller assembly body 4 to move above the concave conveyor frame 3. Then, the drive assembly is operated to drive the concave conveyor frame 3 carrying the new roller assembly body 4 to the assembly position of the roller assembly body 4 in the steel pipe production line. Then, the bearing drive frame 9 is operated to drive the new roller assembly body 4 into the production line until it reaches the preset position and the assembly of the roller assembly body 4 is completed. After that, the bearing drive frame 9 is reset, and the replacement operation of the roller assembly body 4 is completed. In this embodiment of the invention, the driving assembly includes a driving screw 2, which is rotatably connected to the center of the machine body 1. A driving sleeve 202 is threadedly connected to the outside of the driving screw 2. Rectangular slots 203 are symmetrically opened on both sides of the top surface of the driving sleeve 202, and telescopic slide plates 204 are slidably connected inside the rectangular slots 203. The two telescopic slide plates 204 are respectively fixedly installed at the bottom of the corresponding concave conveyor frame 3, and are used to drive the driving sleeve 202 and the concave conveyor frame 3 to translate along the top of the machine body 1 by rotating the driving screw 2. In this embodiment of the invention, the inner sides of the machine body 1 are symmetrically provided with limiting slots 5, and the two concave conveyor frames 3 are provided with sliding plate frames 6 at both ends. The sliding plate frames 6 are slidably connected to the corresponding limiting slots 5. The inner sides of the sliding plate frames 6 are slidably connected with limiting slide rods 7. The ends of the limiting slide rods 7 are fixedly connected to the bottom of the corresponding concave conveyor frame 3. The sliding plate frames 6 are fixedly installed with a drive cylinder 8. The piston end of the drive cylinder 8 is fixedly connected to the middle of the corresponding concave conveyor frame 3 for driving the concave conveyor frame 3 to adjust its height. In this embodiment of the invention, by rotating the drive screw 2, the drive bushing 202 can mesh with the drive screw 2, thereby driving the two concave conveyor frames 3 to move horizontally on the top of the machine body 1, thus completing the position adjustment of the concave conveyor frames 3; In this embodiment of the invention, when the height of the concave conveyor frame 3 needs to be adjusted for the disassembly or assembly of the roller assembly body 4, the drive cylinders 8 at the bottom of both ends of the concave conveyor frame 3 can be driven to move up or down by running simultaneously. At this time, the limit slide rod 7 can slide inside the corresponding sliding plate frame 6, and the telescopic slide plate 204 can slide inside the corresponding rectangular slot 203. In this embodiment of the invention, the two concave conveyor frames 3 are kept in a sliding connection. By adjusting the height and position of the concave conveyor frames 3, the height of the concave conveyor frames 3 and the corresponding bearing drive frames 9 can be finely adjusted during the assembly or disassembly of the roller assembly body 4. This improves the roller changing efficiency of the equipment and expands the applicability of the equipment. In this embodiment of the invention, a drive motor 201 is fixedly installed on the outer side of the machine body 1, and the output end of the drive motor 201 is connected to the end of the drive screw 2 through a coupling.

In this embodiment of the invention, the drive module 13 is an existing motor device, and its output end is connected to the corresponding conveyor wheel assembly 10. It can drive the conveyor wheel assembly 10 to perform forward and reverse operations through the output end of the drive module 13, thereby driving the bearing drive frame 9 to perform bidirectional translation operations and realizing the conveying operation of the roller group body 4. In this embodiment of the invention, two conductive sheets 12 are fixedly installed on the inner sides of the corresponding concave conveying frame 3. The top of each of the two conductive sheets 12 is slidably connected to a conductive frame 121. An inner slide 122 is slidably connected inside the conductive frame 121. The inner slide 122 is fixedly installed at the bottom of the corresponding bearing drive frame 9. The inner slide 122 is electrically connected to the drive module 13 through a wire. In this embodiment of the invention, by setting the conductive sheet 12, when the carrying drive frame 9 moves into the production line, it can simultaneously drive the inner slide 122 and the conductive frame 121 to slide above the conductive sheet 12. When the carrying drive frame 9 disengages from the corresponding concave conveyor frame 3 and enters the production line, it can extend between the inner slide 122 and the conductive frame 121, always maintaining the power supply effect between the drive module 13 and the conductive sheet 12. At the same time, it increases the movement range of the concave conveyor frame 3, enabling the equipment to perform conveying operations for different types of roller body 4. In this embodiment of the invention, the two conductive sheets 12 inside the same concave conveyor frame 3 are respectively the positive and negative poles, and the two conductive sheets 12 are respectively connected to the driving power supply through wires, which will not be described in detail here.

Each outer side of the plurality of elastic cleaning end heads 15 is fixedly installed with an elastic cleaning scraper 151. A transmission belt 142 is rotatably connected between the plurality of cleaning shafts 141. In this embodiment of the invention, the cleaning shaft 141 is driven by a separate motor, which will not be described in detail here; In this embodiment of the invention, a collection tray frame 16 is fixedly installed on the inner bottom of the machine body 1. The collection tray frame 16 is used to collect the cleaned impurities.
