Helical pipeline concrete automatic transport device

Abstract

The invention discloses a helical pipeline concrete automatic transport device. The helical pipeline concrete automatic transport device is characterized in that wheel seats, a speed reducer and a drive gear are fixed in a machine frame, a transport pipe is limited and fixed among positioning wheels in the wheel seats, multiple groups of helical blades are arranged on the inner wall of the transport pipe, annular rail rings are fixed on the outer edge of the transport pipe, and clamped in grooves in the positioning wheels, inner rings are installed on a part, corresponding to the drive gear, of the outer edge of the transport pipe, and meshed with one another, a horizontal adjusting lead screw is hinged between a feeding hopper and the machine frame which are connected in a through mode through the transport pipe, a discharging hopper and walking wheels are connected with the part, at the right end of the transport pipe, of the machine frame, and an angle adjusting lead screw is hingedbetween each walking wheel and the machine frame. The helical pipeline concrete automatic transport device not only completes horizontal transport of concrete, but also can complete transport in thedirection at an angle larger than 45 degrees with the horizontal plane, not only can transport the concrete, but also can transport gravels and cement powder materials, saves energy and protects environment, is reasonable in structure, simple and convenient to operate, high in safety performance and strong in stability, overcomes the defects existing in existing leakage groove and concrete delivery pump transport, and can completely accord with quality and safety requirements.

Description

technical field [0001] The invention relates to a concrete conveying device, in particular to a spiral type pipeline concrete automatic conveying device, which belongs to the field of construction machinery. Background technique [0002] With the rapid development of infrastructure such as highways and urban subways, a large amount of concrete needs to be used in the construction of road and bridge tunnels and bridge piers, underground abutments, culverts, retaining walls, etc. Pour quality. [0003] At present, when the concrete is transported below the ground level, the chute is generally used. However, due to the large drop in the chute, the stones and mortar mixed into the concrete are free to fall, so it is easy to form the free fall of the mortar and concentrate directly below. Larger stones are mostly splashed around, which reduces the mixing standard of concrete and seriously affects the strength and quality of concrete construction projects; concrete delivery pumps...

AI Technical Summary

Problems solved by technology

[0003] At present, when the concrete is conveyed below the ground level, the chute is generally used, but because the chute conveys a large drop, the stones and mortar mixed into the concrete are free to fall, so it is easy to form the free fall of the mortar and concentrate directly below, while Larger stones are mostly splashed around, which reduces the mixing standard of concrete and seriously affects the strength and quality of concrete construction projects; concrete delivery pumps are generally used to transport concrete when constructing above the ground, and concrete delivery pumps are usually used for concrete needs. Projects with a large amount of use and high construction points are carried out, but because the concrete delivery pump and delivery vehicle are large in size and heavy, transportation and on-site construction are inconvenient, and more importantly, the concrete delivery pump and delivery vehicle cannot be used for horizontal construction Point-to-point concrete delivery

At present, there is no automatic conveying of concrete in the spiral pipeline that can complete the horizontal conveying of concrete, and can also complete the conveying of concrete at 45 degrees above the horizontal level. It can convey not only mixed concrete, but also sand, gravel and cement powder. device
