A Foldable Deep Ditch Cable Lifting Device

Abstract

The invention discloses a folding type deep trench cable lifting device, which comprises a bottom plate and a support plate, two first hinge blocks are fixedly installed on one side of the top of the bottom plate, and a first hinge shaft is hinged inside the two first hinge blocks, The outer sides of both ends of the first hinge shaft are fixedly equipped with a first folding rod, and the inside of the end of the first folding rod away from the first hinge shaft is movably hinged with a second hinge shaft, and the outer sides of both ends of the second hinge shaft are fixedly installed with a second folding rod. rod, the opposite side of the second folding rod is fixedly equipped with a suspension plate, and the bottom of the suspension plate is fixedly equipped with a suspension hook. Through the cooperation between the first hinge block, the first hinge shaft, the first folding rod, the second hinge shaft and the second folding rod, it is convenient to fold and store the device, so that it is convenient to transport the device into the narrow space, so that it is convenient Lifting the power cables facilitates the maintenance of damaged power cables by electric power workers, reduces the time and physical strength consumed for maintenance, and improves the efficiency of emergency repair work.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and in particular relates to a folding deep trench cable lifting device. Background technique [0002] In recent years, with the construction and development of cities, compared with traditional overhead lines, power cable lines have gradually shown the characteristics of less urban space, safety, and stability. However, in operation, the power cable line will inevitably cause cable line accidents due to external force damage, natural factors, poor manufacturing process, insulation aging and moisture, etc., and the power cable needs to be overhauled. During the overhaul, the power cable needs to be lifted. Power cables need to be hoisted. [0003] Most of the existing lifting tools are cranes or booms. However, due to historical reasons, the development of the distribution network is regionally unbalanced. In the old urban areas of some cities, it is often difficult to overhaul ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a foldable deep trench cable lifting device to solve the problem that the existing cable lifting device proposed in the above background technology is in use, due to the narrow space in the well, some on-site cranes cannot drive in or the crane arm The safety distance after lifting is not enough, so some on-site emergency repair personnel need to use tools such as crowbars and hemp ropes, which leads to a large amount of manpower to pull the faulty cable to a suitable position, which consumes more time and physical strength, and reduces the cost of emergency repair work. problem of efficiency
