[0032] The embodiment of the present application discloses an external grinding trolley with a gear transmission device, referring to Figure 1 , including a frame 1, a plurality of rollers 11 are provided on both sides of the lower side of the frame 1, the rollers 11 rotate along the guide rails 12, and a rotating roller 13 is provided on the frame 1 along the length direction of the frame 1. There are two rotating rollers 13 and they are distributed parallel to each other. The steel pipe to be processed is placed on the upper side of the two rotating rollers 13.

[0033] Reference Figure 1 A chain track 14 is provided in the middle position of the guide rail 12, and a geared wheel 2 is rotatably installed on one side of the frame 1, and one side of the geared wheel 2 is engaged with the chain track 14. A driving mechanism 3 is provided on the frame 1, and the driving mechanism 3 drives the geared wheel 2 to rotate. The geared wheel 2 rotates along the engaged chain track 14, driving the frame 1 to move along the guide rail 12 to transport the steel pipe. When the trolley moves, the geared wheel 2 is engaged with the chain track 14, and the trolley moves at a constant speed along the guide rail 12, ensuring that the steel pipe travels at a uniform speed. The surface of the steel pipe is well-evened during grinding, and local wear marks are not prone to occur.

[0034] Reference Figure 1 and Figure 2 The driving mechanism 3 includes a driving motor 31 and a reducer 32. The driving motor 31 and the reducer 32 are both arranged on the frame 1 and on one side of the rotating roller 13. The output shaft of the driving motor 31 is connected to the input shaft of the reducer 32. A connecting member 4 is provided on one side of the reducer 32. The connecting member 4 includes a first sprocket 41 and a chain 42. The first sprocket 41 is coaxially connected to the output shaft of the reducer 32. A protective cover 5 is provided at one end of the frame 1. A rotating rod 51 is rotatably installed inside the protective cover 5. The rotating rod 51 is distributed along the width direction of the frame 1. The geared wheel 2 is coaxially connected to the rotating rod 51. A second sprocket 52 is coaxially provided on the rotating rod 51 on one side of the geared wheel 2. The chain 42 is wound around the first sprocket 41 and the second sprocket 52. A through hole for the chain 42 to pass through is opened on one side of the protective cover 5.

[0035] The driving motor 31 drives the reducer 32 to drive the first sprocket 41 to rotate. The first sprocket 41 drives the second sprocket 52 to rotate through the chain 42 and then drives the rotating rod 51 to rotate. The rotating rod 51 drives the geared wheel 2 to rotate and then drives the trolley to move. The reducer 32 decelerates the geared wheel 2, which can effectively control the travel speed of the steel pipe on the trolley. The second sprocket 52 on the rotating rod 51 and the geared wheel 2 are covered on the inner side of the protective cover 5 to reduce the phenomenon of jamming during rotation caused by the entry of debris.

[0036] Reference Figure 2 and Figure 3 A connecting rod 53 is rotatably installed in the protective cover 5. The connecting rod 53 and the rotating rod 51 are parallel to each other.

A first gear 511 is coaxially arranged on the rotating rod 51, and a second gear 531 is coaxially arranged on the connecting rod 53. One side of the first gear 511 is meshed with the second gear 531. When the rotating rod 51 rotates, the first gear 511 drives the meshed second gear 531 to rotate and then drives the connecting rod 53 to rotate. The connecting rod 53 drives the cleaning wheel 6 to rotate to clean the chain track 14. Cleaning is performed while the trolley is moving, reducing the probability of vibration caused by the geared wheel 2 pressing on debris after rotation, thereby reducing the probability of indentations caused by grinding on the steel pipe.

[0037] Reference Figure 3 A ventilation hole 141 is provided on the lower side of the chain track 14. When debris falls to the lower side of the chain track 14, the debris can be taken out manually through the ventilation hole 141, which is convenient for cleaning.
