PROBLEM TO BE SOLVED: To provide a compression adjustment device which enables anyone to easily and appropriately adjust compression strength that determines connection performance of a trolley wire.SOLUTION: A compression adjustment device 1 is provided in an ordinary temperature pressure-welding device in which two trolley wires T1, T2 are respectively held in a stationary chuck C1 and a movable chuck C2 and the two trolley wires T1, T2 are pressure-weld and connected by making the movable chuck C2 approach the stationary chuck C1, releasing holding members H1, H2 and making the movable chuck C2 retreat, to abut end faces of the trolley wires T1, T2 against each other. In the compression adjustment device 1, an attachment frame 2 that is fixed to the stationary chuck C1 is extended along the movement direction of the movable chuck C2, and a ball screw 3 and a rotary encoder 4 are fixed in the attachment frame 2. A screw shaft 7 is screwed to a slide block 8 that is fixed to the movement chuck C2, and the ball screw 3 rotates the screw shaft 7 accompanying the movement of the slide block 8. The rotary encoder 4 rotates together with the screw shaft 7 to output rotational displacement which is counted by a control unit, and the control unit performs movement control to position the movable chuck C2.SELECTED DRAWING: Figure 4 |
