[0021] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-5 As shown, the pipe transfer device of this utility model includes a body 1. The upper surface of the body 1 is provided with a stacking frame 11 and an extension frame 12, and the inner cavity of the extension frame 12 is connected to the stacking frame 11. The bottom surface of the body 1 is provided with a support plate 2 and several traveling wheels 4. The bottom of the body 1 is provided with a mounting cavity 13, the opening of the mounting cavity 13 is facing downward, and the support plate 2 covers the opening of the mounting cavity 13. The mounting cavity 13 is provided with a lifting mechanism, which includes a motor 3, a sleeve 31 and a screw 32. The upper end of the sleeve 31 is rotatably connected to the body 1, the upper end of the screw 32 is threadedly connected to the sleeve 31, and the lower end of the screw 32 is connected to the support plate 2. The motor 3 is fixedly installed in the mounting cavity 13 and is connected to the sleeve 31 through a transmission mechanism. The main body 1 can be used to dock with metal tube polishing equipment. The extension frame 12 is matched with the metal tube polishing outlet. The processed tube can slide from the extension frame 12 into the stacking frame 11. Of course, the staff needs to organize the tube in the stacking frame 11 so that the tube is stacked inside the stacking frame 11. Then the support plate 2 is put away, and the tube is transferred to the subsequent packaging process by several traveling wheels 4.

[0023] The motor 3, sleeve 31, and screw 32 are disposed within the mounting cavity 13. The motor 3 drives the sleeve 31, causing the screw 32 to move vertically along it, thereby driving the support plate 2 to move towards or away from the bottom surface. When the support plate 2 is supported on the ground, the lifting mechanism continues to operate, which can raise the main body 1, making the height of the extension frame 12 adaptable to various models of metal tube polishing equipment, thus accurately matching the discharge port of the polishing machine.

[0024] Specifically, in the field of metal surface treatment processing, such as polishing, grinding, and plating equipment, the discharge port heights are different. The main body 1 can adjust the height of the extension frame 12 via a lifting device to adapt to the discharge port of different equipment, and the processed pipe enters the extension frame 12. (See attached image) Figure 1 As shown, the front end of the extension frame 12 has a slot 120. After the extension frame 12 is adapted to the height of the discharge port, the pipe can slide from the slot 120 into the stacking frame 11 through the extension frame 12.

[0025] The extension frame 12 connects to the stacking frame 11, allowing workers to easily pull the packaged pipes into the stacking frame 11. As is well known, to ensure smooth operation, the stacking frame 11 is a sloping platform; one side of the stacking frame 11 connected to the extension frame 12 is higher and flush with it, while the other side is lower. This allows the pipes to roll and stack towards the lower side of the stacking frame 11 without hindering their movement from the extension frame 12 to the stacking frame 11. Once a sufficient number of pipes are in the stacking frame 11, the lifting mechanism retracts the support plate 2, allowing the main body 1 to be moved via several wheels 4 to the subsequent packaging stage.

[0026] It is understandable that the polishing equipment has a processing cycle, i.e., there is a material discharge interval. During this interval, workers can also package the pipes inside the extension frame 12, such as by covering them with plastic film or anti-collision sleeves. The extension frame 12 is connected to the stacking frame 11, and workers can pull the pipes covered with protective film into the stacking frame 11 to avoid accidental bumps and damage to the polished pipes during long-distance transportation.

[0027] Preferably, a support plate 2 is provided on the bottom surface of the main body 1. The support plate 2 can support the main body 1 through a lifting mechanism, so that the height of the extension frame 12 on it is accurately matched with the polishing outlet of the metal tube. The support plate 2 is set in close contact with the ground, and a number of anti-slip ribs 22 are provided on the support plate 2 to ensure the stability of the main body 1 on the ground.

[0028] The lifting mechanism also includes a guide frame 21, which is movably inserted into the mounting cavity 13. The lower end of the screw 32 is connected to the guide frame 21, and the guide frame 21 is connected to the support plate 2 via a connecting rod. The guide frame 21 is used to ensure the operational stability of the lifting mechanism. It is understood that the upper end of the sleeve 31 is connected to the mounting cavity 13 via a bearing, and the motor 3 can drive the sleeve 31 to rotate via a transmission mechanism. The screw 32 and the sleeve 31 are connected by a thread, and the screw 32 is connected to the mounting cavity 13 via the guide frame 21. The guide frame 21 can only move vertically and cannot rotate within the mounting cavity 13. Specifically, the inner wall of the mounting cavity 13 has a vertical groove, and the guide frame 31 is slidably connected to the groove via a tenon block, thereby limiting the guide frame 21 and the screw 32 in the circumferential direction, so that the guide frame 21 can only move vertically up and down. Furthermore, when the motor 3 drives the sleeve 31 to rotate, the screw 32, guide frame 21 and support plate 2 can be driven to move up and down through the threaded transmission connection.

[0029] The transmission mechanism includes a first gear 33 and a second gear 34. The first gear 33 is mounted on the output shaft 35 of the motor 3, and the second gear 34 is mounted on the sleeve 31. The first gear 33 and the second gear 34 are meshed together, thereby connecting the motor 3 and the sleeve 31. The transmission mechanism can be an existing gear drive, belt drive, or other methods. This invention can adopt a relatively simple gear drive structure, using the first gear 33 and the second gear 34 for transmission. When the motor 3 rotates forward and reverse, it outputs torque through the output shaft 35 to drive the support plate 2 to rise and fall.

[0030] The mounting cavity 13 is equipped with a support plate 14, and a limiting sleeve 15 is provided on the support plate 14. The lower end of the output shaft 35 of the motor 3 passes through the limiting sleeve 15. The output shaft 35 of the motor 3 is provided with a roller groove 36, and a plurality of balls 16 are provided in the roller groove 36. The output shaft 35 of the motor 3 is rotatably connected to the limiting sleeve 15 through the plurality of balls 16. The support plate 14 is used to set the limiting sleeve 15. The upper end of the motor 3 is connected to the mounting cavity 13 through a flange. The lower output shaft 35 of the motor 3 needs to output torque. Therefore, the limiting sleeve 15 and the balls 16 can stabilize the operation of the lower output shaft 35 of the motor 3 and prevent shaking.

[0031] A reinforcing rib 17 is connected between the extension frame 12 and the main body 1, and the reinforcing rib 17 can improve the structural strength of the extension frame 12.

[0032] The stacking frame 11 is provided with several buckles 23, and the buckles 23 are connected to straps 24 that pass through the stacking frame 11. When there are enough pipes on the stacking frame 11, the pipes on the stacking frame 11 are tied and fixed by the straps 24 to prevent the pipes from falling off accidentally during the transportation of the main body 1 by the wheels 4.

[0033] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
