Mining suspension movable type intelligent grouting system

Abstract

The invention discloses a mining suspension movable type intelligent grouting system. The mining suspension movable type intelligent grouting system comprises a horizontal bin pump, a suspension guide rail, a driving and braking device, a suspension movable wheel set, a movable stock bin, a quantitative feeding mechanism, a stirring mechanism, a grouting pump and a control device. According to the mining suspension movable type intelligent grouting system, a novel mining powdery or granular material pneumatic conveying system is adopted for remotely conveying powdery materials to the movable stock bin capable of freely moving along the guide rail through a conveying pipeline for material-gas separation; automatic feeding is carried out according to the demand quantity of the powder materials through a mixed material conveying device and the quantitative feeding mechanism; quantitative water supply is realized according to a set water-cement ratio, and the water-cement ratio and stirring quality of slurry are stably controlled; the grouting pressure and the grouting amount of the grouting pump are detected in real time during grouting, the problem of judgment according to experience is solved, the grouting reinforcement effect is greatly improved, the grouting operation process is simplified, the labor intensity of workers is reduced, automatic control and fine management are achieved, the operation cost is reduced, and the grouting reinforcement quality is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of coal mine roadway support, in particular to a mining suspension mobile intelligent grouting system. Background technique [0002] In coal mine roadway support engineering, the method of anchor net support and grouting filling reinforcement is often used. With the increase of coal mine mining depth, higher requirements are put forward for the support strength and support quality, and grouting reinforcement is one of them. important link. At present, the following problems often exist in the grouting reinforcement construction of coal mines: (1). At present, the powder materials used for grouting in coal mines are usually transported by bagged mine trucks, and the transportation efficiency is low. Manually unpacking the bag to feed the mixer, the labor intensity of the operator is high, and the dust during feeding and mixing is difficult to solve, which affects the health of the operator; (2) In the proces...

AI Technical Summary

Problems solved by technology

At present, the following problems often exist in the grouting reinforcement construction of coal mines: (1) At present, the powder materials for grouting in coal mines are usually transported by bagged mine trucks, the transportation efficiency is low, and there are potential safety hazards when transporting by mine trucks in inclined lanes

Manually unpacking the bag to feed the mixer, the labor intensity of the operator is high, and the dust during feeding and mixing is difficult to deal with, which affects the health of the operator; (2) In the process of grouting slurry preparation, manual feeding and water injection are more affected by human factors If the water-cement ratio is large, the control of the water-cement ratio is often not strict. The slurry mixing is mainly based on experience, and the water-cement ratio cannot be controlled in the best range. After grouting, the initial setting and final setting time cannot be controlled, and the initial and later strength and The performance is difficult to guarantee, which directly affects the roadway support effect, and even brings safety hazards; (3), grouting reinforcement is a hidden project, and the control of the grouting end standard is not strict, and the actual grouting volume and grouting pressure can only be observed manually Or empirical judgment, it is difficult to guarantee the grouting effect, and it cannot be verified afterwards; (4), the grouting reinforcement construction operation is labor-intensive and low in efficiency; (5), there is no record of the grouting reinforcement, and when problems arise, the construction technology and management The data cannot be queried, and it is difficult to judge the construction quality
