The application belongs to the technical field of building construction, and particularly relates to a precast beam hoisting and transporting device, which comprises a hoisting beam, a sling, a first half sliding sleeve, a second half sliding sleeve and a reset spring. Before the precast beam is hoisted and transported, the reset spring at both ends of the inner cavity is pushed to make the first half sliding sleeve and the second half sliding sleeve be at the central position of the inner cavity, so that the length of both ends of the sling is always consistent. During the hoisting and transporting of the precast beam, when the precast beam is slightly inclined, the sling drives the first half sliding sleeve and the second half sliding sleeve to slide along the inner cavity to the side, the reset spring at the side is compressed, and the reset spring at the other side is stretched. The elastic force generated by the reset springs at both sides can make the first half sliding sleeve and the second half sliding sleeve reset to the central position of the inner cavity, drive the height of both ends of the sling to return to the horizontal state, thereby adjusting and restoring the precast beam to the horizontal state, and then the stability and safety of the hoisting and transporting of the precast beam are improved.

The application discloses a planting disc conveying trolley and a planting disc conveying system, and belongs to the technical field of conveying equipment. The planting disc conveying trolley comprises a trolley body, the trolley body comprises a base, a first side plate, a second side plate and a third side plate, wherein the first side plate, the second side plate and the third side plate are perpendicularly fixed on the base and surround to form a bearing space capable of accommodating at least one planting disc; at least two supporting parts are arranged on the base along the length direction of the trolley body, and are used for supporting the planting disc, so that a gap is formed between the bottom of the planting disc and the base; the middle part of the third side plate is opened, so that the side of the base towards the opening protrudes and extends to form an integrated connecting part, at least one slot-shaped hollow opening is formed in the vertical direction of the base, and the connecting hole at the bottom of the slot-shaped hollow opening can be connected with a driving assembly.
