[0035] Working principle:

[0036] In use, the clamping seat 11 and the clamping arm 14 are respectively located on the upper and lower sides of the frame body of the conveyor near the carrier roller. Then, the clamping arm 14 is moved to be close to the other end of the clamping seat 11 to be clamped by applying force to rotate the drive screw 12, and the stability is enhanced by the force grooves 3.

[0037] After clamping and fixing, one end of the inserting arm 22 in the supporting belt structure 2 installed on the bearing box 21 through the butt bolt 23 is inserted into the first or second inserting hole of the clamping seat 11, and is tightly fixed by the installation bolt 15. According to the position to be supported, the inserting arm 22 can be moved left and right on the clamping seat 11 to be adjusted.

[0038] Then, the top supporting pipe 251 is penetrated through the spiral pipe 247 to be supported on the conveying belt by applying force to rotate the top supporting pipe 251 through the second handle 252 in the top supporting assembly 25. Alternatively, the first clamping plate 253 is located below the conveying belt, the second clamping plate 255 is located above the conveying belt by rotating the clamping bolt 254 to clamp the conveying belt, and then the top supporting pipe 251 is rotated to support and lift up.

[0039] The support height and angle of the top support tube 251 are related to the extension length and the inclination angle of the top support tube 251; the inclination angle of the top support tube 251 is achieved by exerting force on the shaft rod 243 through the second handle 252, and since the shaft rod 243 is movably penetrated through the sleeve 241, the second ratchet wheel 245 is rotated counterclockwise, and the second ratchet wheel 245 is forced to keep engaged with the first ratchet wheel 242 through the spring 244, so it cannot be rotated clockwise by the gravity of the conveyor belt, that is, the support is locked, so that the device has a certain space for replacing the carrier roller;

[0040] After use, the top support tube 251 can be reset for further counterclockwise rotation after being removed, or before being removed, the first clamp plate 253 and the second clamp plate 255 are separated from the conveyor belt, and the spring 244 located in the bearing box 21 is compressed by pulling the rotating seat 246, at this time the second ratchet wheel 245 moves to the right by a certain distance to separate from the first ratchet wheel 242, and then the clockwise reset can be performed.

[0041] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
