Slide-transmission wire used in overhead crane

Abstract

The invention provides a novel trolley copper slide wire used in an overhead crane. The invention belongs to the field of overhead crane equipment. The slide-transmission wire provided by the invention comprises truss-type big iron towers (1) used for placing suspension wire ceramic bottles; suspension wire ceramic bottles (2) used for tensioning a cable; a CT-series copper trolley wire (3); a slide block (4) with a conductive effect; an electricity collection frame (5) with an electricity transmission function; a universal joint (6) used for preventing the electricity collection frame (5) from being stuck; an overhead crane electricity transmission fixing frame (7); a reversed-L-shaped small iron tower (8) used for fixing the trolley wire (3); counterweights (9) used for tensioning the trolley wire (3); and diagonal bars (10) used for stabilizing the big iron towers. With the slide-transmission wire provided by the invention, overhead crane failure rate can be reduced, overhead crane service life can be prolonged, and maintenance cost can be reduced. The structure is simple, and operation and application are convenient. With the slide-transmission wire, equipment normal operation can be safely, reliably, and stably ensured.

Description

technical field [0001] The invention relates to the field of cranes in the petrochemical industry, in particular to a sliding transmission line for a crane. Background technique [0002] The decoking crane is one of the indispensable equipment for the normal operation of the coking unit. With the enlargement of the coking unit, the scale of the decoking crane has also become larger and larger, from the original 5-ton crane used in the coking unit to the current 20-ton crane. For a coking unit with one furnace and two towers, there are usually two cranes, and the scale of the two cranes should be able to run for 8 hours a day to clean up the coke in the two towers. [0003] The decoking overhead crane sliding lines used in the delayed coking units of various oil refineries have many failures, such as hanging, jamming or even breaking, which bring safety hazards to the normal operation of the overhead crane and affect work efficiency. Especially in recent years, with the con...

AI Technical Summary

Problems solved by technology

The plastic protective sleeve will be deformed due to the change of external temperature, and the vibration of the carbon brush due to the braking of the crane will also produce a certain impact on it, resulting in the overall bending and deformation of the sliding transmission line track, especially in winter. The protective sleeve is easy to be brittle, so there are often accidents where the carbon brush gets stuck and the slip line is twisted or the slip line breaks the collector frame.

The existing coking unit has a high failure rate of the crane sliding transmission line, high frequency of parts replacement, frequent failures such as hanging, jamming, and breaking, which affect the normal operation of the equipment, and the daily maintenance costs are high, which brings unsafe hidden dangers to the normal operation of the device
