Installation and construction method of portal rake machine applied in plateau area

Abstract

The invention discloses a mounting construction method for a door-type material raking machine applied to a high altitude area. The mounting construction method comprises the steps that step 1, parts of the door-type material raking machine are customized; step 2, an appropriate position is selected in the high attitude area according to conditions, and a building cuboid material pool is poured; step 3, two tracks are parallelly mounted on the two sides of the material pool; step 4, the rest part of the door-type material raking machine but a door frame is mounted; and step 5, a complete door frame is formed by splicing a middle part of the door frame and two side parts of the door frame; and then the middle part of the door frame and the two side parts of the door frame are correspondingly hoisted by utilizing three cranes, the fact that the side parts of the door frame are spliced on a base is achieved. According to the mounting construction method for the door-type material raking machine applied to the high altitude area, operation is easy, high attitude operation is reduced, and the safety coefficient is effectively improved; and height adjusting of an rake arm in the material raking machine can be adjusted with the quantity of materials, the material raking effect is good through secondary material raking, and the working efficiency is improved greatly.

Description

technical field [0001] The invention relates to the field of portal raking machines, in particular to a method for installing and constructing portal raking machines used in plateau areas. Background technique [0002] Potassium is an essential nutrient element for crop growth. About 95% of potassium salt in the world is used to produce potash fertilizers. The potassium salt industry is an irreplaceable basic industry in the current agricultural economy. The main products are potassium chloride and potassium sulfate. Therefore, potassium salt Rational exploitation and utilization of food is directly related to national food security and the survival and development of human beings. Since 2008, with the high global potash price and the huge profits of the potash industry, potash projects have sprung up all over the world. [0003] As the core equipment of the feeding device, the first device of the potassium salt project, the portal rake machine is located at an altitude of ...

AI Technical Summary

Problems solved by technology

[0003] As the core equipment of the feeding device, the first device of the potassium salt project, the portal rake machine is located at an altitude of 3665 meters above sea level, and the span of the portal rake machine reaches 33 meters. The span and difficulty are very high; and the raking effect of the raking machines on the market is not good, and it cannot be flexibly changed with the change of materials
