Description

Technical Field

[0001] The utility model relates to the technical field of shield tail brush disassembly, in particular to a wear-resistant shield tail brush disassembly device. Background Art

[0002] The wear-resistant shield machine is a tunnel boring machine that uses the shield method. The basic working principle of the shield machine is that a cylindrical steel component moves forward along the axis of the tunnel while excavating the soil. The shell of the cylindrical component is the shield. At the tail of the shield, in order to prevent external soil, sand, mud or groundwater from penetrating into the shell of the shield machine, a circle of shield tail brushes must be fixed and welded at the tail of the shield machine. However, as the use time increases, the shield tail brush will gradually wear out. In order to ensure the sealing of the shield machine, the shield tail brush must be replaced regularly. At present, when replacing the shield tail brush, the staff first removes the old shield tail brush from the shield tail with a handheld air planer gun, then uses an angle grinder to grind the end face of the air planer on the shield machine, grinds the end face flat, and then fixes and welds the new shield tail brush to the shield machine; however, when removing the shield tail brush, it is labor-intensive and inconvenient to use if it is manually performed by a handheld air planer and a handheld angle grinder, so a device that can automatically remove the shield tail brush is needed.
