Abstract

The invention discloses a mud-water balance type rock pipe jacking machine and solves technical problems of proneness to breakage, low speed, low safety, low environmental friendliness and expensiveness in existing rock crushing. The mud-water balance type rock pipe jacking machine comprises a front barrel, a rear barrel, a crushing chamber component, a cutter disc component, a cutter disc drivingunit, an electrical control system and a hydraulic control system. The front barrel and the rear barrel are connected through corrective oil cylinders which are connected with displacement sensors, and a steel wire and a seal ring are mounted between the front barrel and the rear barrel. The crushing chamber component is mounted at one end, away from the rear barrel, of the front barrel; the cutter disc component is mounted at one end, away from the front barrel, of the crushing chamber component. The cutter disc driving unit is positioned in the front barrel and the rear barrel, a speed reducer of the cutter disc driving unit is connected with a gear shaft, and a grinding plate is mounted between the crushing chamber component and the interior of the front barrel. The mud-water balance type rock pipe jacking machine is high in construction precision, convenience and safety in ground centralized control, remarkable in project comprehensive benefits and technically suitable for extensive large and medium sized cities.

Description

technical field [0001] The invention relates to a pipe jacking machine, in particular to a mud-water balanced rock pipe jacking machine, which belongs to the technical field of construction engineering. Background technique [0002] The mud-water balance rock pipe jacking machine is a special construction project for rock tunnels. It is suitable for various weathered rock soil conditions, and has been more and more widely used in rock tunnel projects such as railways, electric power, water conservancy, coal, mining, transportation, urban underground engineering machines, and subways. The water balance rock pipe jacking machine is an important equipment for rock tunnel construction, mainly used for cutting rock, breaking rock and transporting the broken rock to complete the construction of rock tunnel. [0003] Rock pipe jacking machines currently on the market are easily damaged due to broken rocks during operation, are slow in speed, unsafe, not environmentally friendly, a...
