[0013] The utility model provides a full-section casting lining trolley, which has the following beneficial effects:
[0014] 1. For the full-section casting lining trolley, the rotating rod rotates to drive the ratchet to rotate, so that the ratchet can only rotate in one direction. At this time, the arc-shaped fixing plate is just inserted into the arc-shaped groove when it rotates. Since the arc-shaped fixing plate and the arc-shaped groove are adapted to each other, the casting pipe can be fixed by the arc-shaped fixing plate. This structure is beneficial to fixing the casting pipe and can avoid the need for manual support when the casting pipe passes through the pouring port for casting, which wastes manpower. Once the manual support is released, the casting pipe is easy to separate from the pouring port, causing the concrete in the casting pipe to fly out.
[0015] 2. For the full-section casting lining trolley, the casting pipe is pulled out from the inside of the pouring port. After the casting pipe is pulled out, the pawl is subjected to the rebound force of the torsion spring, which can drive the pawl and the ratchet to fit together. This structure is beneficial to resetting the pawl position to limit the ratchet, so as to facilitate the fixation of the casting pipe next time. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Specifically, when the casting tube needs to be pulled out, the pull rope 10 can be pulled, and the pull rope 10 drives the pawl 5 to rotate. At this time, the ratchet 4 loses the limit of the pawl 5, and the casting tube is pulled out from the inside of the pouring port 13. After the casting tube is pulled out, the pawl 5 is subjected to the rebound force of the torsion spring 6, which can drive the pawl 5 and the ratchet 4 to fit together. This structure is beneficial to resetting the position of the pawl 5 to limit the ratchet 4, so as to facilitate the fixation of the casting tube next time.
[0026] Working principle: The rotation of the arc-shaped fixing plate 3 drives the rotating rod 2 to rotate, and the rotation of the rotating rod 2 drives the ratchet 4 to rotate. At this time, since the pawl 5 is limited by the ratchet 4, the ratchet 4 can only rotate in one direction. At this time, when the arc-shaped fixing plate 3 rotates, the arc-shaped fixing plate 3 is just stuck into the arc-shaped groove 9. Since the arc-shaped fixing plate 3 and the arc-shaped groove 9 are adapted to each other, the casting pipe can be fixed by the arc-shaped fixing plate 3.
