[0050] Exemplarily, see Figure 1 , Figure 2, the turntable base 10 is used to be fixed in the tunnel during the charging operation and install and support other components. The turntable 11 is rotatably connected to the turntable base 10 through a vertically arranged first rotating shaft 17, so that the turntable 11 can rotate around the first rotating shaft 17. The turntable driving member 12 is connected between the turntable base 10 and the turntable 11 and is used to provide power to drive the turntable 11 to rotate around the first rotating shaft 17, thereby realizing the swing of the turntable 11 on the horizontal plane. One end of the boom 13 is rotatably connected to the turntable 11 through a horizontally arranged second rotating shaft 25, so that the boom 13 can rotate around the second rotating shaft 25. The boom lifting cylinder 14 is arranged below the boom 13. Both ends of the boom lifting cylinder 14 are hinged to the boom 13 and the turntable 11 respectively. By the extension and contraction of the boom lifting cylinder 14, the boom 13 is driven to rotate around the second rotating shaft 25, thereby realizing the swing of the boom 13 in the vertical plane perpendicular to the second rotating shaft 25.

[0051] A boom system provided by an embodiment of the present application is used to assist operators in the charging operation in the tunnel. The specific charging operation process is as follows: The boom system is sent to the construction position in front of the heading face in the tunnel, the turntable base 10 is fixed in the tunnel, and the operation platform is installed on the sub-boom 15; The turntable driving member 12 drives the turntable 11 to drive the boom 13 to swing on the horizontal plane, and the boom 13 drives the sub-boom 15 and the operation platform thereon to move horizontally along the heading face. The boom lifting cylinder 14 drives the boom 13 to swing in the vertical plane, and the boom 13 drives the sub-boom 15 and the operation platform thereon to move vertically along the heading face. Thus, the operation platform can be moved to any charging position on the heading face; When the operation platform moves to the charging position, the operator stands on the operation platform and uses the charging equipment to load the on-site mixed emulsion explosive into the blast hole at the charging position. During this process, the sub-boom lifting cylinder 16 drives the sub-boom 15 to swing in the vertical plane, and the sub-boom 15 drives the operation platform to swing in the vertical plane, which is used to finely adjust the position of the operation platform to level the operation platform moved to any charging position, avoid the skew of the operation platform, and improve the stability and reliability of the operator standing in the operation platform for the charging operation.

[0052] Wherein, the horizontal direction of the heading face refers to the horizontal direction perpendicular to the tunnel axis, that is, the width direction of the tunnel; The vertical direction of the heading face refers to the vertical direction perpendicular to the tunnel axis, that is, the direction from the bottom to the top of the tunnel.

[0053] The boom system provided by the embodiment of the present application is used to assist operators in the charging operation in the tunnel; during the charging process, the turntable driving member 12 drives the turntable 11 to drive the boom 13 to swing in the horizontal plane, and the boom lifting cylinder 14 drives the boom 13 to swing in the vertical plane, so as to realize the horizontal and vertical movement of the boom 13 on the heading face. Thus, the operator can be quickly sent to different charging positions on the heading face through the boom 13 for charging operations; compared with the existing charging methods, the labor intensity is reduced, the charging efficiency is improved, at the same time, the coordination difficulty of on-site construction is reduced, and the flexibility of the operation is improved.
