[0002] Grouting bolt support is a surrounding rock reinforcement method in underground geotechnical engineering such as coal mine roadway support. The high-pressure grouting pipe is an important channel for grouting bolt grouting. The high-pressure grouting pipe connection device is used to assist the connection Grouting anchors, grouting anchor rotating machines, high-pressure grouting pipes and grouting pumps can extend the pipeline to meet the actual needs of the construction site or laboratory, so the high-pressure grouting pipe connection device plays a vital role; the existing The connecting device used in the technology usually corresponds to a type of high-pressure grouting pipe interface of one type, and has no diameter-reducing function. If the construction site or laboratory needs a variable-diameter connecting device, it needs to be contacted with the manufacturer in advance. It is a waste of time and cost a lot of money, and the probability that the variable diameter connection device is suitable for other pipeline connections is extremely low; therefore, it is necessary to design a reusable, good sealing performance and can match a variety of models High-pressure grouting pipe connection device is necessary
