Dredging device for concrete pump pipe

Abstract

The invention discloses a dredging device for a concrete pump pipe. The device comprises a driving device and a helical blade (3), wherein a motor (1) and a speed reducer (2) are fixed into the whole driving device; the helical blade (3) is connected with the speed reducer (2); the driving device is arranged on a case (6); a U-shaped groove (4) is formed under the helical blade (3); one end of the U-shaped groove (4) is fixed together with the speed reducer (2), and the lower part of the U-shaped groove is fixedly arranged on a bracket (5); one end of the bracket (5) is fixed together with the case (6); universal wheels (8) are fixedly arranged at the bottom of the bracket (5); a pushing handle (7) is fixedly arranged outside the case (6). The dredging device is simple in structure and ingenious in design; initially set concrete deposited in the pump pipe can be effectively and rapidly discharged, so that the working efficiency can be greatly improved, and the dredging labor intensity is reduced.

Description

technical field [0001] The invention relates to the field of construction machinery manufacturing, in particular to a device for dredging concrete pump pipes. Background technique [0002] In the construction of slab pouring, it is often difficult to reach the automobile pump due to the complex terrain or high floor height of the construction site. The flexibility of the pump can bypass the obstacles that various automobile pumps cannot reach, but in the actual use process, it will be found that when pouring concrete with a high grade or a large slump, it is very easy to block the pipe. Especially in extreme weather conditions such as extreme heat or severe cold, this situation is extremely obvious. At this time, workers need to disassemble the pump pipe step by step to dredge. Steel rods are poked through, and the whole dredging process is relatively difficult, which not only delays work efficiency, but also has a greater labor intensity. Contents of the invention [00...

[0002] In the construction of slab pouring, it is often difficult to reach the automobile pump due to the complex terrain or high floor height of the construction site. The flexibility of the pump can bypass the obstacles that various automobile pumps cannot reach, but in the actual use process, it will be found that when pouring concrete with a high grade or a large slump, it is very easy to block the pipe. Especially in extreme weather conditions such as extreme heat or severe cold, this situation is extremely obvious. At this time, workers need to disassemble the pump pipe step by step to dredge, and the common dredging method is to use steel pipes welded on the top when the concrete is initially set. The whole dredging process is relatively difficult, which not only delays the work efficiency, but also has a high labor intensity.
