The flip-type upper cover 3 is provided with at least one upper load-bearing rolling assembly 31, and the upper load-bearing rolling assembly 31 is rotatably connected to the flip-type upper cover 3. The upper load-bearing rolling assembly 31 and the lower load-bearing rolling assembly 21 are configured to be respectively connected with the load-bearing main shaft 6 during operation.

[0023] It should be noted that the two ends of the flip-type upper cover 3 are respectively connected to the shaft seat fixing shell 2 by a rotational connection and a detachable connection. When disassembly is required, the flip-type upper cover 3 can be disassembled at the detachable connection position between the shaft seat fixing shell 2, and then the flip-type upper cover 3 can be flipped upward to achieve the purpose of quickly disassembling the load-bearing main shaft 6 and the load-bearing shaft seat.

[0024] The shaft seat fixing shell 2 is connected to the base 1 by a fixed connection method such as welding or a detachable connection method such as a threaded nut set, so as to ensure that the shaft seat fixing shell 2 is fixed to the base 1 in the working state; A cylindrical through hole is provided between the shaft seat fixing shell 2 and the flip cover 3 so that the load-bearing main shaft 6 can pass through the shaft seat fixing shell 2 and the flip cover 3. The upper load-bearing rolling assembly 31 and the lower load-bearing rolling assembly 21 are respectively connected with the load-bearing main shaft 6 in the working state to limit and support the load-bearing main shaft 6; When the load-bearing main shaft 6 rotates, it will drive the upper load-bearing rolling assembly 31 and the lower load-bearing rolling assembly 21 to rotate, so that in the working state, almost no friction resistance and almost no friction heat energy are generated between the load-bearing main shaft 6 and the upper load-bearing rolling assembly 31 and the lower load-bearing rolling assembly 21, thereby improving work efficiency and service life.

[0025] In a further implementation of this embodiment, the lower load-bearing rolling assembly 21 includes a lower load-bearing roller 211 and a lower load-bearing roller pin 212, and the lower load-bearing roller 211 is connected to the shaft seat fixing shell 2 through the lower load-bearing roller pin 212; The upper load-bearing rolling assembly 31 includes an upper load-bearing roller 311 and an upper load-bearing roller pin 312 . The upper load-bearing roller 311 is connected to the flip-type upper cover 3 via the upper load-bearing roller pin 312 .

The two ends of the upper load-bearing roller pin 312 respectively penetrate the side wall of the flip-type upper cover 3 and can be rotatably connected to the flip-type upper cover 3. When the load-bearing main shaft 6 is in a working state, the load-bearing main shaft 6 drives the lower load-bearing roller 211 and the upper load-bearing roller 311 to rotate respectively during rotation. There is no frictional sliding displacement relationship between the load-bearing main shaft 6 and the lower load-bearing roller 211 and the upper load-bearing roller 311, so almost no frictional resistance and almost no frictional heat energy are generated, thereby improving work efficiency and service life.
