Working principle and working device of insulation tackle for live working

Abstract

The invention discloses a working principle and a working device of an insulation tackle for live working. The working device comprises a tackle portion, a hanging point portion and a sealing portion, wherein the tackle portion comprises a first insulation main board, a second insulation main board, a first insulation auxiliary board, a second insulation auxiliary board, a pulley and a pulley shaft; the hanging point portion comprises a suspension beam; the sealing portion comprises a suspension ring, an insulation rope and a safety hook; the first insulation auxiliary board and the second insulation auxiliary board are located at the both sides of the pulley; one end of the first insulation main board and one end of the second insulation main board are arranged at the outer sides of the first insulation auxiliary board and the second insulation auxiliary board respectively; the first insulation main board, the first insulation auxiliary board, the second insulation auxiliary board and the second insulation main board are movably connected in sequence through the pulley shaft, and fixed through nuts; the suspension beam is fixed between the other end of the first insulation main board and the other end of the second insulation main board through a nut; one end of the insulation role is connected with the safety hook, and the other end of the insulation role is in closed connection with the suspension ring; the suspension ring is connected with the suspension beam through a bolt. The insulation tackle disclosed by the invention is light in weight, simple in structure, high in university, and safe and reliable.

Description

technical field [0001] The invention relates to a working principle and a device of a lifting tool, in particular to a working principle and a device of an insulating pulley for live working. Background technique [0002] In the live work, the live work block is one of the essential working tools, which is often used for lifting tools, materials and escorting personnel into the potential. The use of a block with superior performance can ensure the safety of the workers and effectively reduce the risk of operation; [0003] At present, there are two types of pulleys used in live work: round hook type and straight hook type, both of which have potential safety hazards. The hidden dangers are as follows: [0004] 1. Appropriate hanging points are required, and the use is limited and not universal. It can only be used on tower materials with angle steel facing upwards; [0005] 2. Due to the large size of the tower, the hook of the pulley cannot completely close the tower in th...

Problems solved by technology

[0004] 1. Appropriate hanging points are required, and the use is limited and not universal. It can only be used on tower materials with angle steel facing upwards;

[0005] 2. Due to the large size of the tower, the hook of the pulley cannot completely close the tower in the hook, so the pulley is not very reliable after being hung, and there is a risk of falling when it is suddenly subjected to external force or the force is unstable;

[0006] 3. The sealing safety device of the round hook block is easy to be damaged, but the straight hook type block has no sealing safety device, so that the block has come out of the sealing and fell to the ground during the process of climbing the tower;

[0007] Because there are above various defects in existing block, there is certain potential safety hazard, therefore
