The invention discloses a constant-tension pay-off device and belongs to the technical field of railway bearing conductor erection. The constant-tension pay-off device comprises a support, a rotary shaft rotationally connected to the support, and a winding device which is fixedly arranged on the rotary shaft and used for winding a bearing conductor. The support is connected to a car body, used forbearing the support, in a sliding mode through sliding rail devices. Moving devices and driving devices are fixedly arranged on the support, the moving devices enable the support to move along the sliding rail devices, the driving devices are used for driving the rotary shaft to rotate and provide tension for the winding device, and the force application direction of the driving devices is opposite to the pay-off direction of the winding device. The constant-tension pay-off device further comprises a guide device used for detecting the position of the bearing conductor and providing an actuating signal for the moving devices, and a control device. The constant-tension pay-off device provided by the invention is high in automation degree can be automatically aligned with a tension application device during paying-off, the tension is constant and can be automatically adjusted, friction between the bearing conductor and the ground and dragging are reduced during paying-off, the service life is long, dismounting and mounting are convenient, guiding is stable, and the device is applicable to all pay-off devices.

    本发明公开了一种恒张力放线装置,属于铁路承导架设技术领域,包括支架、转动连接于支架上的转轴、固设于转轴上用于缠绕承导线的绕线装置,支架通过滑轨装置滑动连接于用于承载支架的车体上,支架上固设有用于使支架沿着滑轨装置运动的移动装置和用于驱动转轴转动并为绕线装置提供张力的驱动装置,驱动装置的施力方向与绕线装置的放线方向相反;还包括用于检测承导线的位置并为移动装置提供动作信号的导向装置和控制装置。本发明的自动化程度高,放线过程中能与张力施加装置自动对齐,张力恒定、并可自动调节张力,减少在放线过程中承导线与地面的摩擦和拉拽,使用寿命长,拆装方便,导向稳定,适用于所有放线装置。
