Embodiment Construction
[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] Such as figure 1 , 2 A wire pulley is shown, which includes wire pulley I1, wire pulley II2 and beam 3. The wire pulley I1 and wire pulley II2 are respectively arranged on the beam 3 through the wire pulley frame I4 and the wire pulley frame II5. Above, the string wheel I1 and the string wheel II2 are arranged above the beam 3, and the two ends of the beam 3 are provided with driving elements, and the bottom of the string wheel frame I4 and the string wheel frame II5 are connected with the rope 6, and the ground The operator controls the wire block to cross the spacer bar through the driving element, which is convenient and quick. In order to ensure the personal safety of the operating personnel, the wire pulley I1, the string pulley II2, the beam 3, the rope 6 and the drive elements are all made of insulating materials.

The invention discloses a wire pulley, and relates to the technical field of electric power facilities. The wire pulley comprises a wire hanging wheel I, a wire hanging wheel II, and a beam. The wire hanging wheel I and the wire hanging wheel II are arranged on the beam through a wire hanging wheel carrier I and a wire hanging wheel carrier II respectively, and the wire hanging wheel I and the wire hanging wheel II are arranged above the beam. The two ends of the beam are each equipped with a driving element. The lower ends of the wire hanging wheel carrier I and the wire hanging wheel carrier II are each connected with a rope. A ground operator makes the wire pulley cross a spacer through the driving elements. An operator standing on an end face operates the driving elements to make the wire pulley smoothly bypass a spacer and reach a defective part of a wire and to lift tools such as a ladder to the height of the wire with the help of the ropes bypassing the lower parts of the wire hanging wheel carrier I and the wire hanging wheel carrier II so as to handle the defect of the wire easily. The wire pulley has the advantages of simple structure and convenient and quick operation, and reduces the labor intensity of workers. With the wire pulley, the operation time is saved greatly, and the construction cost is reduced.
Description
technical field [0001] The invention relates to the technical field of electric power facilities, in particular to a wire block. Background technique [0002] Under the effect of the rapid development of modern science and technology, with the continuous improvement of the design level of power transmission, the height of the iron tower is increasing year by year. The traditional rope-throwing method of hanging the overhead block is difficult to succeed. Only by personnel climbing up the pole tower to hang the overhead block, and using the overhead block to deal with defects such as broken wires on the wire. However, during high-voltage power transmission, it is often necessary to divide a high-voltage line of a certain phase into two sub-conductors, also known as "high-voltage horizontal double-split lines", which is convenient for manufacturing and construction, and can also transmit a larger amount of current. Between the two sub-conductors Spacer bars are usually provid...
