[0023] To enable those skilled in the art to better understand the present utility model, the technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] As Figure 1 , Figure 2 shown, the vertical rotary chain floating base device of the present utility model includes a mounting frame 1, on which a set of guide wheels 2 and a set of flat wheels 3 are installed. The mounting frame 1 is lap-mounted with a floating bottom plate 4 through the guide wheels 2 and the flat wheels 3. Two sets of springs 5 are connected between the floating bottom plate 4 and the mounting frame 1. A motor mounting plate 6 is installed on the floating bottom plate 4, and an adjustment mechanism 7 is installed between the motor mounting plate 6 and the floating bottom plate 4. A driving motor 8 is installed on the motor mounting plate 6, and a transmission sprocket 9 is installed at the output end of the driving motor 8;

[0025] Two bearing seats 10 are fixedly installed on the mounting frame 1, and a rotating shaft 11 is installed together with the two bearing seats 10. One end of the rotating shaft 11 is fixedly connected to a driven sprocket 12, and the other end of the rotating shaft 11 is fixedly connected to a conveying side sprocket 13. A transmission chain 14 is connected between the driven sprocket 12 and the transmission sprocket 9;

[0026] A limit switch 15 is fixedly installed on the mounting frame 1, and a switch trigger plate 16 corresponding to the output end of the limit switch 15 is installed on the floating bottom plate 4.

[0027] In this embodiment, when using the vertical rotary chain floating base device, the rotary chain on the conveying side is connected to the conveying side sprocket 13, which is the load side;

[0028] When the driving motor 8 on the motor mounting plate 6 operates, it drives the transmission sprocket 9 to rotate. Driven by the transmission chain 14, the driven sprocket 12 is driven to rotate, and then the rotating shaft 11 is driven to rotate, so as to achieve the purpose of transmitting power to the conveying side sprocket 13. When the load is too large, to prevent the transmission chain 14 from jumping off the sprocket, the transmission sprocket 9 will vibrate in the direction of the driven sprocket 12. Since the floating bottom plate 4 is supported by the springs 5, the floating bottom plate 4 will move in the direction of the springs 5 to achieve the purpose of unloading the load. When the load changes violently, the moving distance of the floating bottom plate 4 will also change beyond the allowable range. This movement will cause the limit switch 15 to trigger the switch trigger plate 16 to achieve the purpose of monitoring and alarming; further, by replacing the springs with different spring amounts, different loads can be adapted, expanding the applicability.

[0029] Preferably, a shaft end cover 17 is installed at the end of the driving motor 8. Such a design strengthens the limiting effect on the transmission sprocket 9 and prevents the transmission sprocket 9 from coming off. In fact, the anti-disengagement structure of the transmission sprocket 9 can also be considered according to specific circumstances.

[0030] Preferably, the adjusting mechanism 7 includes a threaded hole plate 71 fixedly mounted on the floating bottom plate 4 and a top plate 72 fixedly mounted on the motor mounting plate 6. The threaded hole plate 71 is threadedly connected with an adjusting bolt 73, and the end of the adjusting bolt 73 contacts the top plate 72. With such a design, by rotating the adjusting bolt 73, the distance between the threaded hole plate 71 and the top plate 72 can be adjusted, thereby achieving the purpose of adjusting the distance between the driving sprocket 9 and the driven sprocket 12, and achieving the purpose of adjusting the tightness of the drive chain 14. In fact, the structure of the adjusting mechanism 7 can also be considered according to specific circumstances.

[0031] Preferably, the one-way cross-section of the guide wheel 2 is V-shaped, and the floating bottom plate 4 is provided with a V-shaped plate 18 matching the guide wheel 2. With such a design, the purpose of left and right limiting is achieved. In fact, the shape and structure of the guide wheel 2 can also be considered according to specific circumstances.

[0032] Preferably, the motor mounting plate 6 is provided with two groups of waist-shaped holes 19, and the motor mounting plate 6 is fixedly mounted on the floating bottom plate 4 through the waist-shaped holes 19. With such a design, while enhancing the installation adaptability of the motor mounting plate 6, the installation and fixing position of the motor mounting plate 6 can be finely adjusted. In fact, the installation structure of the motor mounting plate 6 can also be considered according to specific circumstances.

[0033] The above embodiments only exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
