Technical Field

[0001] The utility model relates to the technical field of electric power construction, and more specifically, to a wire pay-off device. Background Art

[0002] With the rapid development of China's economy, the demand for electric power is growing continuously. There is a need to develop a power transmission technology with large transmission capacity, long distance and high efficiency to meet the demand for large-scale, long-distance and high-efficiency power transmission. In order to improve the power transmission efficiency and reduce losses, large-section wires have been adopted in domestic transmission lines.

[0003] At present, most wire pay-off trolleys used on the market are single three-wheel wire pay-off trolleys for wire pay-off construction. However, during the large-span construction process, due to factors such as large span, heavy wire and large tension, the rated load and stress requirements of the current single three-wheel wire pay-off trolley can no longer meet the pay-off requirements of this large-span. Therefore, it is necessary to optimize the design of the structure of the wire pay-off device to ensure that the strength and safety of the wire pay-off device meet the engineering application requirements. Summary of the Utility Model

[0012] The connecting rod has an inclined angle after being connected to the upright.

[0013] The connecting rod is parallel to the horizontal line, and the inclination angle between the upright and the connecting rod is 3°~5°.

[0014] In actual construction, the conductor laying device is suspended at a high position by connecting it to construction tools such as hanging plates and hardware.
