[0007] Furthermore, a retaining ring is provided on the outer wall of the inclined steel pipe, and a wire rope clamp is provided at the lower end of the lower wire rope, with the lower end of the lower wire rope being looped onto the retaining ring.

[0008] Furthermore, the inclined steel pipe includes at least one section of telescopic steel pipe.

[0009] Furthermore, the telescopic steel pipe includes an outer telescopic steel pipe and an inner telescopic steel pipe that is axially movably nested within the outer telescopic steel pipe.

[0010] Furthermore, the inner telescopic steel pipe has a spring plate on its side wall, the end of the spring plate is overhanging and has a locking pin, and the side wall of the inner telescopic steel pipe has a through hole for the locking pin to pass through; the side wall of the outer telescopic steel pipe has a plurality of fixed-distance holes spaced along the axial direction for the locking pin to pass through.

[0011] Furthermore, the inclined steel pipe includes two telescopic steel pipe sections and a connecting flange connecting the two telescopic steel pipe sections; each telescopic steel pipe section is provided with a suspension device.

The adjusting rope of the suspension device is wound or released using a winding device to adjust the height of the suspension components and the inclined steel pipe suspended below them. In operation, the suspension angle of the inclined steel pipe is adjustable, allowing the end of the inclined steel pipe to serve as a concrete outlet, thus enabling adjustment of the discharge position. The inclined steel pipe includes at least one section of telescopic steel pipe, allowing for length adjustment and ultimately, adjustment of the concrete pumping height and position. This avoids the problems of fixed chute delivery routes and space occupation associated with traditional full-span scaffolding support methods. It improves construction efficiency, saves construction time, and reduces construction costs while effectively ensuring concrete quality. Under the same requirements, using this suspended chute device reduces energy consumption of pumping equipment and scaffolding erection costs, reduces carbon emissions, and embodies green construction. By setting up movable and fixed pulleys, the entire suspended chute device is balanced and stable during the pouring process. The height, pouring angle and pouring distance can be flexibly adjusted according to actual needs, thus adapting to foundation pits of different depths or building floor slabs of different heights. It can be disassembled and reused, reducing construction costs and has strong social promotion value. Attached Figure Description
