Embodiment Construction

[0024] Such as figure 1 As shown, the transmission line channel crossing protection mechanism of the present invention includes: two mounting parts, one pay-off pulley, two insulated lifting ropes 7 and an insulated traction rope 8.

[0025] Among them, the two mounting parts are both formed by connecting the upper pulley and the lower pulley, and the lower side of the upper pulley is provided with a socket for the upper pulley to be mounted on the cable; the pay-off pulley is composed of a supporting pulley and two swinging installations The two insulating connecting rods 2 on both sides of the opening above the supporting pulley are formed; one end of the two insulating lifting ropes 7 respectively bypasses the lower pulleys of the two hanging parts and is connected to the upper ends of the two insulating connecting rods 2; One end is connected under the supporting pulley.

[0026] Such as figure 1 , 5 As shown in and 6, the upper pulley is composed of the upper pulley support 4....

Abstract

The invention provides a power transmission line channel crossing protection mechanism comprising two mounting parts, a line laying pulley, two insulation lifting ropes and an insulation haulage rope; the two mounting parts respectively comprise an upper pulley and a lower pulley connected together; a side face below the upper pulley is provided with a jack allowing the upper pulley to hang on a cable; the line laying pulley comprises a support pulley and two insulation connecting rods arranged on two sides of an opening above the support pulley in a swing mode; one ends of the two insulation lifting ropes respectively wind the lower pulley of the two mounting parts, and are connected with the tops of the two insulation connecting rods; one end of the insulation haulage rope is connected below the support pulley. The power transmission line channel crossing protection mechanism needs no crossing rack, is small in construction engineering work load, high in mounting safety, and has good application prospect.

Description

Technical field [0001] The invention relates to a cable construction tool, in particular to a crossover protection mechanism for transmission line channels. Background technique [0002] In circuit construction, it is often necessary to replace the conductor and ground wires. In order to protect the facilities that are crossed below, such as power lines, roads, railways, rivers, and residential buildings, protective measures are usually taken, such as low-voltage power transmission or distribution lines. Power outages; roads and railways need to be closed. [0003] In the process of replacing the ground wire, in order to ensure that the replaced ground wire will not fall down due to insufficient tension, which will cause an impact on the facilities to be crossed, a spanning frame is usually used, which is higher than the facility to be crossed, so that the replaced guide The ground wire falls on the spanning frame, and the main tools used are: bamboo, iron wire, etc. The process i...
