Concrete long distance linear distribution system and method

Abstract

A long-distance linear distribution system for concrete is provided, comprising: a first distribution machine, which is fixedly arranged on site and includes a rotatable first arm and a second arm; and includes a rotatable third arm rod and a fourth arm rod; and a concrete conveying pipe, including a plurality of sub conveying pipes hinged with each other through joints, the first end of the concrete conveying pipe is connected to the concrete conveying pump, and the second end is connected to the pouring nozzle; Wherein, the plurality of sub-conveying pipes between the uprights of the first distributing machine and the uprights of the second distributing machine can be changed between an extended state and a folded state with the reciprocating running of the second distributing machine. The distribution port can move in a straight line at a constant speed, and the pouring of the components can achieve precise and continuous operation at the same time.

Problems solved by technology

[0002] At present, the prefabricated construction industry is developing very rapidly, and various manufacturers have developed various types of concrete pouring equipment. However, the existing concrete pouring methods in engineering buildings are all centered on the distribution machine, using the rotation of the arm to move in the circumferential direction. It is impossible to achieve continuous and accurate pouring along the straight line. Although the pouring speed is very fast, it cannot be used for the production of concrete components. It is only suitable for engineering buildings. Concrete component factories use hoppers for pouring. But its pouring speed is slow and far behind the production capacity of the mixing system

This leads to large equipment investment and low output, causing many other production equipment to be idle, seriously affecting production efficiency and increasing labor costs

[0003] At the same time, at present, the production plants of prefabricated components of buildings mostly use concrete hoppers for pouring. Although the pouring efficiency has been improved through technological updates, continuous operation cannot be achieved.

Its pouring speed is still far behind the production capacity of the mixing system

If a fixed concrete placing machine is used, due to the limitation of the plant conditions, the distributing radius is small and the distributing accuracy is not enough, and a large amount of manpower is required to assist the concrete pouring operation

Moreover, the arrangement of component molds in building assembly factories is linear, which needs to form an assembly line operation, while the operating range of fixed distributing machines is circular, and its distributing efficiency cannot be effectively utilized

As a result, the pouring scheme using concrete delivery pumps combined with concrete distribution machines cannot be applied in the production of prefabricated factories
