摘要： A cutting assembly for a mining machine includes a central hub having at least one arm extending radially outwards from the central hub. The arm includes at least one cutting means carrier movably arranged for radial movement along the arm and a primary actuator configured to control the radial position of the cutting means carrier. The cutting assembly further includes a locking means movable between an unlocked and a locked position, wherein the locking means in its locked position locks the cutting means carrier to the arm such that radial movement of the cutting means carrier is prevented. The locking means includes at least one locking member provided on the arm such that the locking member is movable between an extended position and a withdrawn position. The locking member in the extended position extends to engage the cutting means carrier such that movement of the cutting means carrier is prevented.

摘要： A laser-assisted tunnel boring machine and a rock fragmenting method thereof belong to the technical field of tunnel engineering. Two rock fragmenting modes exist: a laser-cutter rock fragmenting mode and a cutter rock fragmenting mode, wherein the two rock fragmenting modes are switched by an intelligent control system; and for the laser-assisted rock fragmenting mode, hot fragmenting is mainly performed using lasers which assisted by water spray systems, to achieve the purposes of auxiliary rock fragmenting by laser radiation for hot cracking and water spray for quick cooling, and mechanical rock fragmenting for excavation.

摘要： Sealing in the sliding gap of a rotating valve is improved to smoothly rotate the rotating valve during replacement of a roller bit. A valve housing portion is formed behind a bit housing portion having an opening at the front of a main cutter spoke. A rotating valve is rotationally disposed as a rotating body in the valve housing portion. A bit case containing the roller bit is moved into the bit housing portion so as to protrude from a removable passage of the rotating valve, and then the bit case is fixed by a cotter member to support a drilling reaction force. Thus, the sliding gap of the rotating valve is disposed in the bit housing portion and the valve housing portion and is covered with the bit case.

摘要： The present invention relates to a tunnel boring machine particularly a micro-tunnelling machine having a cutting head rotatably mounted on the end of a housing and being driven by a first motor means and a rotatable central auger for removal of soil from the cutting operation mounted in the interior of the housing, the central auger being driven by a second motor means to allow rotation of the auger independent of the rotation of the cutting head. The tunnel boring machine may also be provided with a rock crusher between the cutting head and the auger to reduce boulders encountered during the tunneling to a size to be able to be transported by the auger.

摘要： A cutterhead is supported at the front part of a main frame so as to incline at a specified angle with respect to a vertical plane. The main frame includes (i) a roof support disposed at a position corresponding to where a reaction force acts in the direction of the periphery of a tunnel against a force caused by rotation of the cutterhead, and (ii) a pusher for pushing the roof support toward the cutterhead resisting the reaction force.

摘要： An earth boring system is disclosed for guiding and steering a string of pipe casings to form an underground cased bore. The string of pipe casings are guided by a boring end assembly including a front casing and a steering head connected at an interface gap by a plurality of hinge assemblies each having an actuator and a pair of connector parts. A protective enclosure protects the hinge assemblies from loosened earth from the earthen bore and from the earth being removed from within the pipe casings. The protective enclosure can be formed by an inner pipe and an outer pipe of both the front casing and the steering head, plus a closure ring and a retainer belt at the interface gap. Guidance sensors are provided to determine the location of the string of pipe casings and a computer control center computes steering head axial and angular displacements for guiding the string of pipe casings and controlling the extent of the interface gap.

摘要： An object of this invention is to improve precision in the operation, operating efficiency, and reliability of an excavator. A soil condition at a place where an excavator (1) is advanced is inputted, and a reference number of revolutions of a cutter (9) and a reference advancing speed of the excavator (1) are set in correspondence with the inputted soil condition. Meanwhile, a load on each actuator (17, 18) is detected. The actuator (18) for rotating the cutter is controlled so as to allow the set reference number of revolutions to be obtained for the cutter (9). In a case where the load on each of the actuators (17, 18) is within a predetermined range, the actuator (17) for advancing is controlled so as to allow the set reference advancing speed to be obtained for the excavator (1). However, in a case where it is detected that the load on either of the actuators (17, 18) is outside the predetermined range, the actuator (17) for advancing is controlled in such a manner as to decrease or increase the advancing speed more than the reference advancing speed.

摘要： Boring apparatus for forming a generally horizontal underground passage in soil for a utility conduit or the like that includes a tool head with a base portion and a nose portion mounted on the base portion. The nose portion is rotatable relative to the base portion between a first position in which nose portion surfaces are symmetrical with respect to the tool axis so that the tool will move along a straight path and a second position in which nose portion surfaces are in asymmetrical position with respect to the tool axis so that said tool will move along a curved path. By application of torque to the base portion, the base portion is shifted relative to the nose portion to shift the tool head from between an asymmetrical configuration and a symmetrical configuration.
