Pumping control method and device, material distribution method and device, and distribution equipment

Abstract

The invention relates to the field of construction machinery, and discloses a pumping control method and device, a material distribution method and device, and distribution equipment. The pumping control method includes: calculating the initial pumping speed; controlling the distribution equipment to pump at the initial pumping speed; and dynamically adjusting the distribution in real time according to the completed real-time distribution volume and real-time distribution time during the pumping of the distribution device The pumping speed of the device until the real-time cloth volume is the desired cloth volume. In this way, the accuracy of the final cloth square quantity is improved. The distribution method includes controlling the distribution equipment to fabricate a position to be distributed in the preset distribution area; and after completing the distribution of the distribution to the position to be distributed, determining the next position to be distributed in the preset distribution area and to the next position to be distributed. Cloth at the cloth position until every position to be clothed in the preset cloth area has been clothed. Thereby, automatic cloth is realized.

Description

technical field [0001] The present invention relates to the field of engineering machinery, in particular to a material distribution control method and device, a material distribution method and device, and material distribution equipment. Background technique [0002] Concrete distributing equipment, such as pump trucks, distributing machines, etc., is a commonly used construction machinery, which is used to transport concrete to a predetermined location through the delivery pipe on the boom. [0003] Concrete distributing equipment needs to be equipped with a manipulator, and the manipulator needs to continuously operate the boom and pump according to the requirements of the construction party to transport the concrete to the designated location. [0004] However, due to the long time of concrete single construction, frequent manipulation, harsh natural environment, and the labor time and intensity of the machine operator are very large, how to realize automatic material d...

Problems solved by technology

[0006] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art. The first technical solution has the following disadvantages: 1) The pouring point is preset in advance, and it cannot be based on the construction requirements and the current location of the equipment distribution point, the concrete label, etc. Dynamically adjust the pouring point, so it cannot adapt to the actual complex construction needs. For example, it is possible to pour C20 grade concrete to the C30 pouring point, which will lead to serious engineering quality; 2) Only consider the pumping time of the pouring point to determine the pumping volume. There is a very large error, because the actual pumping volume is related to many factors such as pumping times, piston stroke and material suction, and it cannot be guaranteed that the material distribution volume of each pouring point meets the construction requirements; 3) the arm is not considered The movement trajectory of the rack to the next pouring point, when encountering obstacles, etc., pause or avoid

Based on the above defects, the first technical solution can only be used in idealized construction scenarios, and cannot be practically popularized and applied

The second technical solution has the following disadvantages: only a variety of distribution path methods are proposed, and there is no explanation for the cooperation with pumping to ensure that the concrete poured during the movement of the boom meets the construction requirements, and there is no basis for the selection of the distribution path
