Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring, in particular to a telescopic pouring and transmission device. Background Art

[0002] This telescopic pouring and conveying equipment is primarily used for heavy concrete pours for the extra-high and extra-thick walls of nuclear power plants. Due to the large volume of concrete being poured, and the fact that the primary aggregates in heavy concrete are hematite and hematite sand, which are prone to aggregate separation, heavy concrete is prone to segregation. Truck-mounted pumps are particularly susceptible to blockage, preventing proper pouring. Furthermore, existing pouring methods, which utilize a tower crane and hopper, are extremely inefficient. Therefore, ensuring material quality and improving pouring efficiency are key challenges in heavy concrete pouring.

[0003] Therefore, it is urgent to propose a telescopic pouring and conveying device with simple structure and convenient use. Utility Model Content
