The rock slag is simply removed by manpower, which is labor-consuming and inefficient. The removal of the rock slag requires an increase in efficiency by mechanical means of transport.
Meanwhile, due to the abrasion of the hob at the cutterhead, the hob needs to be replaced in time in order to ensure the normal tunneling of the TBM of the tunnel boring machine. The traditional method is that a hydraulic winch is arranged at the lower part of a host machine, a hob is dragged through a steel wire rope, a fixed pulley is arranged below a bottom shield in front of the host machine, the dragging direction of the steel wire rope is changed through the fixed pulley, an old hob detached from a cutterhead is dragged back to the hydraulic winch at the rear of the host machine, the steel wire rope is required to be hung on the fixed pulley again when a new hob is conveyed, and then the steel wire rope is dragged back to the rear of the host machine to be dragged and conveyed.
The traditional cutter changing process in TBM construction is low in efficiency, a person is required to drag a steel wire rope on a hydraulic winch in the process of replacing a new hob and transporting the old hob, and particularly the process of transporting the 17-inch center double-edge hob is quite inconvenient. When the hob is dragged by the steel wire rope at the bottom of the tunnel, the hob is particularly easy to be clamped due to the rock slag accumulated at the bottom of the tunnel, and once the hob is clamped, accidents can be caused, so that the safety risk is high.
If the diameter of the tunnel is smaller than 4m, the space inside the shield body and the space occupied by the solid part of the host machine in front of the TBM are larger, so that the operation space for personnel is relatively narrow, a mechanism is needed to be utilized, the machine is multipurpose, and the use requirements of slag removal and knife transportation are met. Therefore, it is necessary to develop a slag removal and cutter handling integrated mechanism for small-diameter TBM heading machines.
