The invention discloses a single-shaft flat-turning pay-off device for a multilayer needle roller bearing. The device comprises a supporting support, a vertical rod support is arranged at the center of the supporting support, a bearing is arranged on the vertical rod support, a pay-off device rotary disc is connected to an outer ring of the bearing, and a sleeve is rotationally arranged on the upper portion of the vertical rod support. A pay-off device rotary drum is welded between the sleeve and the pay-off device rotary disc. By the adoption of the single-shaft horizontal-rotation pay-off device for the multilayer needle roller bearing, installation is extremely convenient during construction, the situation that electric wires are damaged during construction and thus the additional workamount is increased is avoided, the quality of raw materials is guaranteed, and the construction cost is greatly reduced.
Description
technical field [0001] The invention relates to the field of wire pay-offs, in particular to a multi-layer needle bearing uniaxial flat rotation pay-off device. Background technique [0002] At present, vertical double-bearing pay-offs are used for wire pay-offs at construction sites. The installation process is extremely inconvenient during the construction process, and the bus bars are easily pulled hard during the pay-off process, resulting in damage to the bus bars. Due to the extremely unstable center of gravity of the vertical pay-off, the frame body falls during the pay-off, which is easy to affect the subsequent electrical construction, cannot guarantee the quality of the raw materials, causes waste of wires and increases the amount of extra engineering, and the secondary repair process is cumbersome. The horizontal rotation pay-off device also solves the problem of wire winding and intertwining. [0003] For the problems in the related technologies, no effective so...
