Concrete distributing machine

Abstract

The invention provides a concrete distributing machine which comprises a trolley, a pipeline system and a telescopic rotating device. The trolley comprises a trolley body, a travelling part and a locking part, and the trolley body comprises a bottom plate. The pipeline system comprises a feeding pipe set, a discharging pipe set and a connecting pipe set, the feeding pipe set is connected with a concrete pumping mechanism, and the connecting pipe set is movably arranged on the trolley body through the telescopic rotating device. By applying the technical scheme of the concrete distributing machine, the effects are that the whole structure is simplified; through combination design of the trolley body and the travelling part, the trolley body advantageously travels by a certain distance on demand; through combination design of the trolley, the pipeline system and telescopic rotating device, the spatial relationship of all pipelines in the pipeline system is advantageously changed, the change of the distance and the position is achieved, then combined with connection of the concrete pumping mechanism, pressurized closed feeding is achieved, concrete distribution is uniform, and the grouting efficiency and the quality of grouted concrete products are greatly improved; and through design of the locking part, the position of the trolley body is advantageously fixed, and the distributing effect of the distributing machine is further optimized.

Description

technical field [0001] The invention relates to the technical field of lining, in particular to a concrete placing machine. Background technique [0002] In the lining process, the commonly used concrete grouting is grouted with a distributing device such as application number 201220331471.7. This device specifically includes a reversing pipe for conveying concrete and a plurality of mold windows connected to the trolley. The concrete import chute, the diverter pipe is arranged above the multiple concrete import chutes, and the outlet end of the diverter pipe can be switched among the plurality of concrete import chutes. [0003] There are following defects in this way: [0004] 1. It is necessary to replace and connect the pump pipe with pipe clamps in the middle, which takes a long time, has low work efficiency, high labor intensity, and the interval between pipe changes is long, which requires high concrete performance. [0005] 2. There are many gate valves, cumbersome...

Problems solved by technology

[0004] 1. It is necessary to replace and connect the pump pipe with a pipe clamp in the middle, which takes a long time, has low work efficiency, high labor intensity, and the interval between pipe changes is long, which requires high concrete performance.

[0005] 2. There are many gate valves, cumbersome operation, and the cooperation of many staff (generally 6-7 people are required); the hopper and chute are all open, and there are many docking points and dead ends, which will easily cause residual concrete to accumulate and troublesome cleaning. Completely, after the residual concrete in this part is solidified, it makes it difficult or impossible to use the equipment; the concrete is conveyed without pressure and flows down by its own weight, and the arrangement of the chute requires a certain angle; the structure is complex, the volume is large, and the site layout is troublesome
