When the transverse plate I12 is not in contact with the bottom surface, the turning plate I17 turns downwards under the action of the neutral position, the elastic force of the spring II 26 pushes the sliding plate I18 to move leftwards, the vertical groove I19 moves leftwards to push the clamping block I20 to move upwards to clamp the sliding plate II 21, the baffle I23 is limited to turn leftwards, the stability of the culvert pipe on the transverse plate I12 in the slow descending process is improved, and the culvert pipe is prevented from rolling leftwards from the transverse plate I12 due to the fact that the baffle I23 turns leftwards undesirably.

When the trolley is used, the transverse plate 12 on the trolley body 10, on which the culvert rolls, is driven by the gravity of the culvert to move downwards, the transverse plate 12 moves downwards to drive the ball 14 to push the vertical rod 15 to rotate by a component force in the horizontal direction of the connecting rod 13, the vertical rod 15 rotates to drive the rotating shaft 39 to rotate, the rotating shaft 39 drives the blades 43 to rotate to stir the non-Newtonian liquid in the shell 38, the rotating speed of the vertical rod 15 is limited by the trapezoid of the non-Newtonian liquid, so that the descending speed of the transverse plate 12 on the vertical rod 15 is limited, the transverse plate 12 slowly descends until the transverse plate is contacted with the bottom surface, the plum downward from the transverse plate 12 is transmitted to the cushion plate 27 through the vertical rod 15, the cushion plate 27 pushes the sliding plate three 28 to slide into the bottom plate 30, the cushion plate 27 moves downwards to push the sliding block one 31 on the pull rod 29 to slide into the pipeline one 32, the sliding block 31 pushes the hydraulic oil in the pipeline one 32 to drive the sliding block two 33 to slide into the pipeline 32 And when the transverse plate I12 descends to be in contact with the bottom surface, the bottom surface pushes the first turnover plate I17 to overturn upwards to drive the sliding plate I18 to slide into the transverse plate I12, the first fixture block 20 falls into the first vertical groove I19 under the action of gravity, the second sliding groove II 25 pushes the ejector rod 24 to move upwards to further overturn the first baffle plate 23 to the left, and the first baffle plate 23 overturns leftwards to push the sliding plate II 21 to move the first compression spring 22 to the left.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
