[0038] The working principle of this embodiment is as follows: when the pipe support mechanism is in an idle state, the piston end of the lifting cylinder 2 is retracted, and the support assembly 3 and the clamping mechanism 4 are in the initial state. At this time, the entire pipe support mechanism is stored inside the frame; when the pipe support mechanism needs to work, the piston end of the lifting cylinder 2 extends out, and the support assembly 3 is lifted to contact the pipe, thereby playing a supporting role for the pipe, and then the two-way cylinder drives the two sets of clamping plate assemblies 42 to approach each other, and clamps the pipe in the center, so that the pipe support mechanism completes the support and centering clamping of the pipe; when the pipe support mechanism is completed, the two-way cylinder drives the two sets of clamping plate assemblies 42 away from the pipe, and the pipe is released, and then the piston end of the lifting cylinder 2 is retracted, driving the support assembly 3 to move downward, and when the trigger plate 5 contacts and triggers the travel switch 62, the travel switch 62 transmits the position signal of the lifting cylinder 2 to the control mechanism, so as to realize the operation control of the lifting cylinder 2, and at this time the lifting cylinder 2 stops running, that is, the pipe support device is restored to its position.
