Rotating wheel type anchor rod construction manipulator and trolley

Abstract

The invention provides a rotating wheel type anchor rod construction manipulator and a trolley. The rotating wheel type anchor rod construction manipulator comprises a center shaft, a drilling assembly, an anchor rod mounting assembly and a post-processing assembly, wherein the drilling assembly, the anchor rod mounting assembly and the post-processing assembly are annularly arranged on the center shaft. The drilling assembly is provided with a data acquisition instrument electrically connected with a control system so as to monitor whether a surrounding rock structure is suddenly changed or not in the drilling process. The anchor rod mounting assembly comprises an anchor rod mounting machine, a prestressed anchor rod bin and a grouting anchor rod bin, wherein the prestressed anchor rod bin and the grouting anchor rod bin are arranged on the two sides of the anchor rod mounting machine correspondingly. The post-processing assembly is connected to a third guide rail so as to conduct post-processing on a prestressed anchor rod body or a grouting anchor rod body driven into surrounding rock. According to the rotating wheel type anchor rod construction manipulator and the trolley, the integrity and the crushing degree of the surrounding rock are obtained by analyzing drilling data, and therefore the type of a prestressed anchor rod or a grouting anchor rod is selected in a self-adaptive mode for construction, the construction quality of the anchor rods is effectively ensured, the safety of workers is ensured, the working efficiency is improved, and automatic, mechanical and digital anchor rod construction is achieved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a wheel-type bolt construction manipulator and trolley. Background technique [0002] With the continuous development of geotechnical engineering and the continuous pursuit of new Austrian methods by many experts and scholars, the support form that uses the anchor rod as the support structure to mobilize the self-bearing capacity of the surrounding rock can effectively control the settlement of the surrounding rock and thus restrict the tunnel opening. In the process of excavation, the damage that may extend to the surface, bolt support is one of the mainstream support methods in underground concealed projects such as former tunnels and chambers. However, the rock formation is a complex heterogeneous structure, due to the differences in lithology, structure, weathering degree, compressive strength, rock structure and mineral composition of the surrounding rocks. The ...

Problems solved by technology

[0003] The bolt construction equipment in the prior art has a single function, and the drilling process is separated from the bolt installation process. It can only be constructed specifically for one kind of bolt, and it is impossible to dynamically select the most suitable anchor according to the actual drilling surrounding rock conditions. For rod support, individual construction steps require manual intervention, such as using high-strength clip-type locks for locking, and the tensioning process requires manual high-altitude tensioning operations. This process has a greater construction risk and consumes a lot of energy. construction cycle time

The construction equipment of the existing technology can no longer meet the construction requirements of the current high-strength prestressed anchor, especially in the past when the prestress was applied based on torque, the prestress applied by this structure is generally small, and the effect of the high-strength prestressed anchor cannot be fully to play

The construction equipment in the prior art has no effective detection of bolt construction quality such as grouting quality and prestress value, but bolt support, as a hidden project, has the characteristics of many quality control nodes and lacks reliable monitoring and detection means The characteristics of closed-loop feedback make it difficult to guarantee the quality of tension construction
