摘要： A tensioning apparatus for pulling together respective ends of a previously severed high-tension cable and, thus, repairing and restoring tension upon a unified cable includes a base member defining a pair of guide channels spaced apart along a common longitudinal axis. The tensioning apparatus includes a pair of tensioning arms positioned in the pair of guide channels, respectively, that is slidably movable between a relaxed configuration displaced from one another and a tensioned configuration proximate one another. Each tensioning arm includes a gripper member configured to clamp onto the respective ends of the severed cable. Hydraulic or pneumatic power is operatively coupled to the pair of tensioning arms for selectively actuating movement of the pair of tensioning arms along the guide channels between the relaxed and tensioned configurations. In other words, the ends of the severed cable are pulled tightly toward one another and joined together under tension.

摘要： A instrument string stretching assembly for stretching instrument strings during the manufacturing process includes a curved panel that has a plurality of channels each extending through the curved panel. A plurality of instrument strings can be inserted into a respective one of the channels having each of the instrument strings extending outwardly through the respective channel. A stretching unit is aligned with each of the plurality of channels in the curved panel and the stretching unit is actuatable into a lifting condition or a lowering condition. A clamping unit is attached to the stretching unit to grip each of the plurality of instrument strings. The stretching unit lifts the clamping unit upwardly thereby stretching the instrument strings along the plurality of channels in the curved panel.

摘要： Disclosed are an apparatus and a method for automatically adjusting the tension on a mining elevator flexible guide rail. The apparatus comprises an automatic tightening apparatus (1) at the opening of the well, and a fixing apparatus (2) on the bottom of the well, respectively connected to two ends of the steel cable (3). The automatic tightening apparatus (1) at the opening of the well is connected to a hydraulic system (5) and to a tension measuring system (4). The automatic tightening apparatus (1) at the opening of the well comprises a lower retainer seat (1-14) arranged on an upper bearer beam (1-1), a tightening oil cylinder body (1-2) and a plunger thereof (1-3), a pin shaft retainer (1-11), a support frame (1-6), a fall-proof holder (1-13), a pin shaft holder (1-5), a fall-proof cable retainer (1-12), a tightening fixed cable retainer (1-10), two guide columns (1-7) and guide grooves thereof, an upper retainer seat (1-9), and a cable orientation-adjusting cable retainer (1-8). The fixing apparatus (2) on the bottom of the well comprises a fixing plate (2-3), and a fixed cable retainer (2-5). The apparatus and the method allow the flexible guide rail to be structurally simple, convenient to process, reliable in performance, and easy to install and to maintain. The apparatus and the method allow restriction of vertical orientation and horizontal deflection, and are capable of real-time detection and automatic adjustment of the tension in the flexible guide rail of the elevator.

摘要： A stretching device for filiform elements comprises a main body member (1) having ends, with one of the ends having a connection opening (2) and the opposite end of the plate member having a rotating mounting opening (3) in the rotating mounting opening there is a rotating part (6) having a command head (11) which forms a winding reel (7) for the wire to be stretched; mounted on the main body (1) is a slide mobile cramp (12). The winding to stretch the element is done by turning the command head (11). Once the suitable stretching has been achieved, the slide mobile cramp (12) is slided until said command head (11) is introduced into the cramp recess (15) formed by the cramp fork (14). Under these conditions, the rotating part (6) is fixed, keeping the tension on the filiform element.

摘要： An apparatus for the formation of a wire loop comprises a wire drive for advancing a wire and a loop layer to grip a first end of the wire and to lay a wire loop. When the wire is advanced, the wire loop is formed into a selected size. The apparatus also includes a pull-out gripper and a sensor device, the pull-out gripper being configured to grasp the wire of the wire loop and, after grasping the wire of the wire loop, move relative to the loop layer, thereby tensioning the wire loop in a longitudinal direction. The sensor device can detect a twist in the wire loop.

摘要： An insulated fence tensioner for use with a flexible polymer fence rail having at least one electrically conductive member has a metal barrel including a slot for receiving an end of the fence rail. An electrically non-conductive tubular liner is situated within the metal barrel, the liner including two edges defining a slot aligned with the metal barrel slot. An electrically non-conductive sleeve surrounds the metal barrel, the sleeve including two edges defining a slot aligned with the metal barrel slot. One set of the liner and sleeve edges are formed as a pair of folded edges positioned to penetrate the metal barrel slot and overlap the other set of the edges. An electrically non-conductive flange is positioned between the electrically conductive member of the flexible polymer fence rail and the metal mounting bracket of the fence tensioner.

摘要： A tool for stretching the individual wire strands of a fence from a slack into a taut condition. The tool is left attached to the tightened wire and can subsequently be employed to further tighten or loosen the wire. The tool has a plurality of slots arranged thereon which engage spaced marginal lengths of the wire. A set of spaced tabs are used to secure the tool to the wire to prevent inadvertent unwinding. A removable handle is provided by which the tool is engaged and manipulated in a manner to fold a length of wire between the slots thereof and back upon itself, and thereafter a pair of spaced tabs engage spaced marginal lengths of the wire to prevent the tool from unwinding from the bent-up wire.
