Wire reeling, unreeling and arranging device with multiple connected trays

Abstract

The invention discloses a wire reeling, unreeling and arranging device with multiple connected trays. The wire reeling, unreeling and arranging device comprises a base, a traction device, an upright post, a platform, a moving trolley, an automatic wire arranging device and trays. The platform is fixed on the base through the upright post. The trays for storing cables are arranged below the platform. The number of the trays is greater than or equal to two. A through wire passing groove is formed above the platform. The wire passing groove is positioned on a center line of the platform and is parallel to the connecting line of the centers of a plurality of trays. The moving trolley is aloes arranged on the platform and can move on the platform. The automatic wire arranging device for arranging a wire is arranged on the moving trolley. The traction device for conveying the cables is also fixed on the base through the upright post. In the device, a plurality of trays are arranged together in a centralized manner, not only can be used for reeling the cables, but also can be used for unreeling the cables; the number of the trays or portal frames can be reduced by 50 percent; the effects of reeling and unreeling a plurality of cables are realized; and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of high-voltage and ultra-high-voltage large-length submarine cables, in particular to a device for collecting, releasing and arranging cables of multiple trays. Background technique [0002] So far, in the entire field of cable production, including high-voltage and ultra-high-voltage submarine cables, wire reels are used to take up and pay off the wires, and the take-up and pay-off racks are of the gantry walking type. [0003] This type of take-up and pay-off device is mainly composed of a lower casing, a column, a tensioning wheel, and a thimble. Not only is the loading capacity extremely limited, but also the functions of the take-up frame and the pay-off frame cannot be interchanged. The main disadvantages are: [0004] 1) The take-up rack is active, it can only take up the wire but not pay it off, otherwise the pay-off rack can only pay off the wire but not take it up; 2) Each set of production equip...

AI Technical Summary

Problems solved by technology

Not only is the loading capacity extremely limited, but also the functions of the take-up frame and the pay-off frame cannot be interchanged. The main disadvantages are:

[0004] 1) The take-up rack is active, it can only take up the wire but not pay it off, otherwise the pay-off rack can only pay off the wire but not take it up; 2) Each set of production equipment needs to be equipped with a passive pay-off rack and an active wire take-up rack , the take-up and release racks of each set of equipment cannot be used uniformly, and occupy a large space; 3) The gantry-type take-up and pay-off racks can currently place a maximum of 5000×2500×2300 (outer diameter of the plate × inner diameter × outer opening file) to produce single cores The length of a single 110kV 500mm2 submarine cable without joints is about 6km, which cannot produce large-length single-core 220kV submarine cables

At present, general users require single-core 110kV submarine cables with a length of more than 20km without joints, and single-core 220kV submarine cables to reach at least 15km, which is far from being met by the original pay-off reel; 0 to 2.5 meters, unilateral width of 0 to 1.2 meters, can not eliminate cable stress well

[0005] In a word, the retracting and unwinding device in the prior art cannot meet the demand for cable retracting and unwinding in cable production
