摘要： A drive system with both fixed-displacement hydraulic motors and variable-displacement hydraulic motors for a cutter head of a boring machine and a control method thereof are provided. The drive system includes a variable-displacement hydraulic motor group, a fixed-displacement hydraulic motor group and a variable-displacement hydraulic pump group. The variable-displacement hydraulic motor group, the fixed-displacement hydraulic motor group, and the variable-displacement hydraulic pump group are all connected to a main oil circuit of a cutter head system of the boring machine. The variable-displacement hydraulic pump group inputs flow to the main oil circuit; and, the variable-displacement hydraulic motor group and the fixed-displacement hydraulic motor group acquire flow from the main oil circuit. Displacements of the fixed-displacement hydraulic motor group and the variable-displacement hydraulic motor group are set in a way of specific displacement combination. The present invention decreases an engineering cost, and improves system reliability and efficiency.

摘要： The apparatus and method of the invention relates to the formation of ducts or passageways, referred to as ducts underground by using existing lengths of plant such as pipes, cables or wires, or a length of plant laid in predetermined position as a guidance or reference for the drill head used to form the duct or passageway as it passes through the ground. The plant is used to generate an electromagnetic field which is sensed by at least one electromagnetic field sensor mounted in the drill head, said sensor rotated to allow comparison of signals and the distance of the drill head from the plant to be calculated. Other sensors can also be provided to determine other positional characteristics of the drill head with respect to the plant. This allows the duct to be formed with the avoidance of potentially hazardous plant and/or along a path which is determined with reference to the plant. The apparatus can also be used as a guidance means without the drill to pass along existing passageways and indicate the path of the same using the same operating procedure.

摘要： An apparatus and method for locating an underground boring tool using a radar-like probe and detection technique. A boring tool is provided with a device which generates a specific signature signal in response to a probe signal transmitted from above the ground. Cooperative operation between the probe signal transmitter at ground level and a signature signal generator disposed within the boring tool provides for the accurate locating of the boring tool, despite the presence of a large background signal. The signature signal produced by the boring tool may be generated either passively or actively, and in a manner which differs from the probe signal in one or more ways, including timing, frequency content, or polarization. A survey of a boring site, made either prior to or during the boring operation, provides data related to the characteristics of the ground medium subjected to the survey and the identification of underground hazards, such as buried utilities. Knowledge of ground characteristics enables estimates of boring productivity and cost to be made. Accurate surveys of planned boring pathways can be made and compared, either contemporaneously or subsequently, against the accurately measured position of the boring tool during a boring operation. The direction of the boring tool may be adjusted in response to the measured position in order to maintain the boring tool along the planned pathway and at an optimum boring rate.
摘要翻译：一种使用雷达式探头和检测技术定位地下钻孔工具的装置和方法。一种无聊工具设置有响应于从地面上方发送的探测信号而产生特定签名信号的设备。地面探测信号发射器与设置在钻孔工具内的签名信号发生器之间的协同操作提供了钻孔工具的精确定位，尽管存在大的背景信号。由钻孔工具产生的签名信号可以被动地或主动地产生，并且以与一个或多个方式（包括定时，频率内容或极化）的探测信号不同的方式产生。在无聊操作之前或期间进行的无聊场地的调查提供了与受检查的地面介质的特征以及地下危害的识别有关的数据，例如埋地式设施。对地面特性的了解使得能够估算出镗孔的生产率和成本。可以在钻孔操作期间对钻孔工具的精确测量位置进行准确的对计划钻孔路径的调查，同时或随后进行比较。可以响应于测量位置来调整钻孔工具的方向，以便沿着规划的路径和最佳的钻孔速度保持钻孔工具。

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： With respect to correcting of a forward movement course of the underground excavator, the control apparatus is so constructed that a positional deviation of the pilot head (20) relative to an excavation planned value is obtained on the basis of detecting of the existent position assumed by the pilot head (20) and the excavation angle correcting means (S1, S2, 21, 23, 41, 71, 72, 73, 80) is provided for automatically correcting an excavating angle of the excavating head (10) on the basis of the positional deviation so as to allow controlling to be achieved automatically. With respect to controlling of start and stop of excavating operation to be performed by the underground excavator, an arrangement is made such that controlling is semiautomatically achieved using the commanding means (74) disposed in the start pit (SH) to issue commands indicative of start and stop of propelling operation of the propelling jack (40) in response to proper manual handling performed by an operator (M) staying on the bottom of the start pit (SH).

摘要： In a control system for synchronous rotation of the cutter heads in a multi-cutter shield machine, the rotation cutter heads are so disposed in generally the same plane such that the distance between the centers of the adjoining cutter heads is larger than the radius, and smaller than the diameter, of the cutter heads. The rotating cutter heads are driven independently of each other by electric drive systems, respectively. Each of the electric drive systems consists of plural motors with a reduction gear, coupled to the respective rotating cutter heads by means of a pinion and gear. The motor rotation is so controlled and the cutter heads are so synchronously rotated, that the angle of deviation between the cutter heads is within such an allowable range that the cutter heads will not interfere with each other even if there is any imbalance in excavating and rotating resistances between the cutter heads.

摘要： An improved golf club shaft and golf club, the shaft being of stepped configuration, having a uniform outer diameter butt end portion having a uniform wall thickness at least 10 inches (254mm) long, the uniform wall thickness being not greater than 0.012 (0.305mm) and a plurality of cylindrical step portions of progressively smaller outer diameter terminating in a tapered tip end portion having a wall thickness at the tip end of at least 0.024 (0.610)mm). The shaft is characterized by a redistribution of metal which results in a balance point closer toward the tip of the shaft, making it possible to use a lighter head without affecting the swing weight.

摘要： A method and apparatus for controlling stratum deformation in a shield construction process, a non-volatile storage medium, and a processor are disclosed. The method includes: monitoring settlement characteristic parameters in a shield construction process; predicting a settlement proportion according to the settlement characteristic parameters, the settlement proportion being a ratio between a predicted settlement value and a corresponding settlement threshold; and determining construction parameters in the shield construction process according to the settlement proportion. In the method, a settlement proportion is predicted through settlement characteristic parameters monitored in a shield construction process, and then appropriate construction parameters are determined according to the settlement proportion, so that the construction parameters in the shield construction process can be corrected in real time, and the safety and scientificity of stratum deformation control in shield construction can be ensured.
