一种高压输电施工时封网用转向滑车
摘要：
本发明提供一种高压输电施工时封网用转向滑车，包括：左立架、右立架、上滑轮、下滑轮、第一轴承、第二轴承；所述上滑轮大于所述下滑轮；所述左立架和右立架之间放置所述上滑轮和下滑轮；所述上滑轮通过所述第一轴承固定在所述左立架和右立架之间；所述下滑轮通过所述第二轴承固定在所述左立架和右立架之间；所述上滑轮上端放置承托绳；所述上滑轮与下滑轮之间形成的空隙放置牵网绳。由于上滑轮和下滑轮上下排列，并且上滑轮的直径大于下滑轮的止境，这样可以保证承托绳和牵网绳不会相互缠绕在一起，从而提高施工效率。
摘要（英）：

The invention provides a steering pulley for net blocking during high-voltage power transmission construction. The steering pulley comprises a left stand, a right stand, an upper pulley, a lower pulley, a first bearing, and a second bearing, the upper pulley is larger than the lower pulley, the upper pulley and the lower pulley are arranged between the left stand and the right stand, the upper pulley is fixed between the left stand and the right stand via the first bearing, the lower pulley is fixed between the left stand and the right stand via the second bearing, the upper end of the upper pulley is provided with a support rope, and a net-pulling rope is arranged in a gap formed between the upper pulley and the lower pulley. According to the steering pulley, the upper pulley and the lower pulley are arranged in a vertical manner, and the diameter of the upper pulley is greater than the diameter of the lower pulley so that the support rope and the net-pulling rope can be prevented from mutually twisting together, and the construction efficiency is improved.
