[0002] Large farms have high requirements for water irrigation. During the construction of large farms, a large number of canals need to be laid. At present, prefabricated canals are mainly used for laying. When laying prefabricated canals, the hoisting equipment lifts the prefabricated canals, and then the adjacent prefabricated canals are manually aligned before the prefabricated canals are lowered. Each prefabricated canal takes a long time to adjust the direction and angle to align with the prefabricated canals that have been laid. The docking of two adjacent prefabricated canals requires a certain degree of precision, so it takes a long time, which is not conducive to the continuity of construction and prolongs the construction period.

When hoisting the subsequent prefabricated water channel 500, after the prefabricated water channel 500 is hoisted to the inclined slide 210, the first hoisting device 230 is manually clamped to the prefabricated water channel 500, and after the hoisting component 100 is released, the prefabricated water channel 500 begins to slide down. The control switch 2311 that slides down to the electric push rod is pushed by the protrusion, and the first hanger 230 is released. At this time, the lower part of the prefabricated water channel 500 has already pushed the prefabricated water channel 500 on the straight slide 310 below and slowly slides down without suddenly sliding down. After sliding down to the straight slide 310, the prefabricated water channel 500 on the inclined slide 210 has a certain driving effect on the prefabricated water channel 500 on the straight slide 310, pushing it to move toward the ground. The force of the second hanger 413 pulling the prefabricated water channel 500 will slow down the descending speed of the prefabricated water channel 500 on the inclined slide 210, thereby protecting the prefabricated water channel 500. The position of the protrusion 214 allows the first hanger 230 to reach the protrusion 214 only after the second hanger 413 slides to the descending channel 4125, thereby preventing the second hanger 413 from losing the power to move to the descending channel 4125.

[0051] Specifically, the length of the inclined slide 210 extending in the left-right direction is slightly greater than the length of a single prefabricated water channel 500, the length of the straight slide 310 is slightly shorter than the length of a single prefabricated water channel 500, the length of the upper rail 4121 and the lower rail 4122 is slightly less than the length of a single prefabricated water channel 500, and the second hanger 413 is clamped at a position slightly to the left of the right end of the prefabricated water channel 500. The upper rail 4121 and the lower rail 4122 are both suspended above the straight slide 310 so that the second hanger 413 clamps the side plate of the prefabricated water channel 500 from above.
