Embodiment Construction
[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many of the details listed in the specification are only for readers to have a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.
[0020] like figure 1 As shown, according to a concrete pumping anti-blocking method of the present invention, the method is to install a "several"-shaped conversion pipe between the downward standpipe and the flat pipe when the tow pump or the vehicle-mounted pump is transporting concrete, " The conversion pipe in the shape of a few" prevents the concrete from flowing out in the flat pipe on the upper part of the standpipe, and the conversion pipe in the shape of...

Abstract
The invention discloses a concrete pumping anti-blocking method and device and belongs to the field of concrete conveying devices. The device is composed of a switching pipe shaped like the Chinese character ji, the switching pipe shaped like the Chinese character ji comprises a transverse pipe and U-shaped pipes symmetrically arranged relative to the transverse pipe, and each U-shaped pipe comprises an arc pipe and S-shaped pipes oppositely arranged relative to the arc pipe. According to the concrete pumping anti-blocking method and device, an inverted-T-shaped pipe is used for a section of distance under a conveying port or a vertical pipe of a pump truck to arrange a pipeline, pipe blocking caused by coarse aggregate accumulation due to a large slump degree and separation of concrete can be effectively relieved as the impact force brought by a fall can be reduced by the inverted-T-shaped arrangement, the height difference of the transverse pipe is used for carrying out compensationconfronting with the vertical pipe, and the situation that blocking occurs when aggregated rock accumulates at turn parts due to the gravity action on the two sides is reduced; besides, it is avoidedthat air enters as empty parts appear in the vertical pipe, and the circumstance that the concrete is likely to condense to cause blocking is relieved; and the turning parts are arranged to be of theU-shaped structures, the S-shaped structures are arranged on the two sides at the same time, and thus blocking of the aggregated rock is effectively avoided.
Description
technical field [0001] The invention relates to the field of concrete conveying devices, in particular to a concrete pumping anti-blocking method and device. Background technique [0002] When the tow pump (vehicle pump) is transporting concrete downwards, the drop is more than 6 meters. As the height increases, the concrete being transported is affected by the acceleration of gravity, so that the concrete in the upper half of the standpipe is easy to flow downward. , so that there is air in the upper part of the pipe, and the sloping concrete coarse aggregate accumulates to the bottom of the standpipe, which is very easy to block the 90° elbow and the butt flat pipe below the standpipe. In order to prevent the above situation, it is necessary to design a concrete pumping anti-blocking method and device to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to provide an anti-blocking method and device for concrete pumping,...
