Shield tunneling machine mud cake removing device and removing method

Abstract

The invention relates to a shield tunneling machine mud cake removing device and removing method. The device comprises a draught fan, a mud suction machine and a main cleaning rotary disc; the main cleaning rotary disc is connected with a cutter head panel of a shield tunneling machine and is used for cleaning mud cakes on a cutter head of the shield tunneling machine; the draught fan is arranged behind the cutter head panel, is positioned above the main cleaning rotary disc and is used for generating cold air; and the mud suction machine is arranged behind the cutter head panel, located below the main cleaning rotary disc and used for generating suction force. According to the technical scheme, the mud cakes are cleaned in a cleaning rotary disc mode, a reverse cleaning method opposite to the rotating direction of a cutter head is achieved through a reverse rotating shaft, and resources are saved; the draught fan is adopted to assist in cleaning, so that the cleaning speed can be increased, the temperature of the cutter head panel can be effectively reduced, and the abrasion condition of a cutter is effectively delayed; and the mud suction machine not only effectively accelerates the cleaning speed of the mud cakes, but also can accelerate the collection work of falling soil, the falling soil is conveyed to a soil bin, and meanwhile, the cleanliness of an empty bin behind the cutter head panel of the shield tunneling machine is guaranteed.

Description

technical field [0001] The invention relates to the field of shield machine auxiliary equipment manufacturing, in particular to a shield machine mud cake removal device and a removal method. Background technique [0002] At present, shield machines are widely used in digging underground tunnels, and are famous for their economy and safety. Among them, during the excavation process of the shield machine, the cutter head needs to continuously cut the soil so that the shield machine can move forward smoothly, but there are often some mud cakes due to the rising temperature during the cutting process or the failure of the muck modifier. Due to the good effect, part of the mud cake formed into a mud cake and stuck on the cutter head, resulting in an increase in the torque of the cutter head and an increase in temperature, which eventually led to severe wear of the cutter head, and the shield machine was forced to stop to replace the cutter. , which will seriously affect the tunn...

Problems solved by technology

Among them, during the tunneling process of the shield machine, the cutter head needs to continuously cut the soil so that the shield machine can move forward smoothly, but there are often some mud cakes due to the rising temperature during the cutting process or the failure of the muck modifier. Due to the good effect, part of the mud cake is formed into a mud cake and sticks to the cutter head, resulting in an increase in the torque of the cutter head and an increase in temperature, which eventually leads to serious wear of the cutter head, and the shield machine is forced to stop to replace the cutter. , which will seriously affect the tunneling speed of the shield machine and delay the construction period

[0003] The problem of mud cake cleaning on the cutter head has not been well solved. The traditional cleaning method not only has insufficient cleaning ability, but also needs to be shut down for cleaning. However, when the shield machine passes through some construction areas, it needs to pass through quickly and stably, and does not have the ability to stop Clean up conditions
