摘要： PURPOSE:To realize stabilized cable laying work by detecting pressure corresponding to tensile force exerted on a cable, controlling the feeding speed of cable such that the detected pressure is kept at a reference level, and stopping feed out of cable when the detected pressure drops below a level corresponding to the rigidity of the cable. CONSTITUTION:A pressure sensor 29 disposed at the tip of a cable 1 in a hauling machine 20 detects pressure corresponding to tensile force exerted on the cable 1. An endless belt 21 feeds out the cable 1 such that the detected pressure is kept at a reference level. The endless belt 21 stops feed out of cable 1 when the pressure detected through the pressure sensor 29 drops below a level corresponding to the rigidity of the cable 1. Tensile force of the cable 1 is detected continuously through the pressure sensor 29 and the cable feeding speed is regulated continuously depending on the tensile force thus detected. A plurality of hauling machines 20 follow up the speed of a preceding of hauling machine 20 continuously thus realizing a stabilized cable laying work as a whole.

摘要： PURPOSE:To obtain a measuring method which facilitates the measurement of delivery speed and length of a cable along with limited measuring errors. CONSTITUTION:In an apparatus which delivers a cable from a cable drum 6, the distance to a rotating shaft of the cable drum from a specified fixed point between flanges of the cable drum 6 is represented by L0 the distance to the outermost circumferential surface of the cable wound on the drum from the fixed point is shown by L(t), and the number of revolutions of the drum by n(t) and the time by t. The rotational speed of the drum is determined by V(t)={L0=Lt}X2pi n(t) and the delivery length of the cable by LT(t)=integral v(t)dt.

摘要： PURPOSE: To execute a tug-of-war even between two distant spots by providing an arithmetic part for calculating traction power from a transmission function containing the PID element of the tug-of-war and a control part for supplying a signal for generating the traction power to a traction power generating means corresponding to that output. CONSTITUTION: A device for tug-of-war is composed of terminals 1 and 1 connected through cable or radio communication lines L1 and L2. A position sensor 4 is linked with a motor 20 and the output of the position sensor 4 is sent to an arithmetic part 5. The arithmetic part 5 is connected to a torque control panel 6, and its amplified output is impressed to the motor 20. When displaced amounts at the respective terminals are defined as X1 and X2 and its sum is defined as ε, tensile force T1 at the terminal 1 is applied by the transmission function containing the PID element of the tug-of-war. Control is enabled only by a proportional term (p). When any coefficient is suitably selected, however, a differentiation term P is contributed to improve followup ability and an integration term I is contributed to improve stability respectively so that a stable control system improved in responsiveness as a whole can be provided. Tensile force T2 at the terminal 1' is equal with T1 .

摘要： PURPOSE:To make unnecessary the support of the winding end part of a cable by coupling the one end of a supporting rope to the area of a cable near the end part thereof, then winding the supporting rope for several turns to the drum body and then supporting the other end of the supporting rope with a braking apparatus. CONSTITUTION:A drum 1 winding a cable 3 is supported on a base 15 with an supporting arm 16 and the cable 3 is guided by an extension roller 4 for supply into a manhole 5. The one end of a supporting rope 25 is coupled with area of the cable 3 near the winding end. The supporting rope 25 is wound for several turns around the body 1A of drum 1, while the other end of the supporting rope 25 is wound for the supporting purpose around a braking apparatus 26 consisting of a winding part 26A and a braking motor 26B. Thereby, it is now unnecessary to support the winding end of the cable 3 and provide a flexible tube in the vertical wall of the manhole and thereby the efficiency of cable laying work can be improved.

摘要： PURPOSE: To enable a single team to practice a tug of war by a method wherein a torque adjuster is arranged between a rotor to which one end of a rope for tug of war is connected, and a motor, and a control device is adjusted by the torque. CONSTITUTION: For a training machine by which a practice of tug of war is performed while assuming an opposite team a torque adjuster such as an electromagnetic clutch brake 3 is connected to the output side of an induction motor 2. Then, a reduction gear 3 is connected through the brake 3, and a capstan drum 5 is connected to the output side of the reduction gear 4, and is rotatably supported by supporting members 6, 6'. First, the braking force of the electromagnetic clutch brake 3 is set by a controller 10, and the induction motor 2 is rotated in one direction, and a rope for tug of war is pulled. When the human force wins, the rope is taken up, and in an opposite case, the rope is pulled out. Also, by a signal of a torque meter 12, a detected value and the set value are compared, and the set value is corrected.

摘要： PROBLEM TO BE SOLVED: To make a cable tension detecting device used for detecting the tension of an optical fiber cable, etc., usable even in a small manhole and, at the same time, to make the device easily mountable by forming the cable connecting section of the detector so that it cannot be caught by inserting metal fittings when the section is passed through the parts and reducing the total length of the device. SOLUTION: When a pressing bolt 27 is screwed in an insert holding section, pressing metal fittings 24 receive an upward vertical force through a see-saw member 25 and are fixed to the inner peripheral surface of a conduit 22 in a state where the member 25 is pressed against the inner peripheral surface and, at the same time, upper inserting metal fittings 17 are concentrically fixed and held in the conduit 22. Because of the pressing force of the bolt 27, the whole bodies of upper and lower inserting metallic parts are strongly pressed against the inner peripheral surface of the conduit 22 and firmly attached and fixed to the inner peripheral surface by a downward vertical force. In addition, the front end section of the lower inserting metal fittings 19 is bent outward along the mouth of the conduit 22 and formed in a notched shape having no projecting section protruded toward the center of a manhole. Therefore, the total length of a cable tension detecting device is reduced and the tension detecting section of the device is brought nearer to the mouth of the conduit 22.

摘要： PURPOSE: To provide a remote controller for controlling controlled systems by comparing preset displacing speed with respective values of displacing speed calculated by inputting the output signals of displaced amount detectors, and providing a controller for respectively outputting control signals corresponding to these compared values to a reverse controller. CONSTITUTION: A remote controller 6 is composed of controlls systems A and B respectively arranged at two distant spots, manipulated variable detectors 1A and 1B, displaced amount detectors 2A and 2B, reverse controllers 3A and 3B, and controller 4. A manipulated variable FA is exerted upon the controlled system A, and a reverse manipulated variable is exerted upon manipulated variables FA and FB at speed corresponding to the displacing speed set by difference FA-FB from the manipulated variable FB exerted upon the other distant controlled system B so that the respective controlled systems A and B can be independently controlled. The manipulated variables FA and FB are respectively independently exerted upon the controlled systems A and B but displaced amounts xA and xB of these controlled systems A and B are respectively detected by the displaced amount detectors 2A and 2B and corresponding to these displaced amounts, the manipulated variables can be adjusted. In this case, the displaced amounts are displayed on display devices 5A and 5B.
