Crane cable for heat treatment workshop

Abstract

The invention belongs to the technical field of machinery, and relates to a hanging cable used in a heat treatment workshop, which solves the problem of low convenience for workers to operate the hanging cable when the workpiece is taken out of the furnace by the hanging cable in the heat treatment workshop of the prior art. The suspension cable of this bank includes several conductors, the conductor is covered with an insulating layer, the insulating layer is covered with a protective layer, the protective layer is covered with a sheath, and the gap between the sheath and the protective layer is filled with flame-retardant particles, and the sheath is along its own length. There is a channel 1 in the direction, and a memory alloy wire 1 is arranged in the channel 1. The memory alloy wire 1 is straight at room temperature. When the memory alloy wire 1 is close to the heated workpiece, it can bend away from the workpiece. The invention can effectively improve the convenience of working operation and hanging.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a hanging cable used in a heat treatment workshop. Background technique [0002] At present, ordinary rubber-sheathed flexible cables are mostly used in the cable industry for moving and winding cables. During operation, the cables are subjected to various mechanical stresses such as frequent bending and stretching, which can easily lead to broken conductors, decreased insulation performance, and braided copper. The wire punctures the insulation layer to cause insulation breakdown and other phenomena, causing the equipment to stop rotating, which seriously affects the normal use of the user and causes great losses to the user. [0003] In order to solve the above problems, the Chinese patent CN 201374211Y discloses a special flat cable for traveling cranes, which extrudes a layer of insulating layer on the outside of a single conductor or a single conductor made of multi-strand u...

Problems solved by technology

However, in the heat treatment workshop, trolley furnaces are often used, usually for processing large workpieces. When in use, when the heating is completed, the furnace door is opened, and the high-temperature large workpieces are sent out of the furnace through the rails. At this time, workers need to pass The high-temperature large workpiece is lifted by the mobile crane. At this time, the distance between the mobile crane motor and the workpiece forms a right-angled
