Supply device and method for long reinforcing steel bars in four-side-ribbed high-speed-rail reinforcing steel bar meshes

Abstract

The invention discloses a supply device and method for long reinforcing steel bars in four-side-ribbed high-speed-rail reinforcing steel bar meshes, and belongs to the field of cold-rolled reinforcingsteel bars. The supply device comprises a reinforcing steel bar coil unwinding device, a reinforcing steel bar straightening roller device, one or more hydraulic reinforcing steel bar shearing devices, a rib arranging stand of a reinforcing steel bar mesh welding device and a moving frame which are arranged sequentially; the moving frame is arranged on the rib arranging stand; a long reinforcingsteel bar fixed-length baffle is arranged on the moving frame; the one or more hydraulic reinforcing steel bar shearing devices are arranged in front of the rib arranging stand; at least one driving roller is arranged in the reinforcing steel bar straightening roller device; and multiple sensors and a controller are arranged in the supply device. By the aid of the supply device, production links of the reinforcing steel bar are reduced, the problem of inconsistency of the parallelism of the reinforcing steel bars during bundling and carrying of the reinforcing steel bars is reduced, the alarming, shutdown or maintenance time of the device is shortened, the running rate of the device is increased, and the percent of pass of the yield strength of the straightened reinforcing steel bars is increased.

Description

technical field [0001] The invention relates to a supply device, in particular to a supply device and a supply method for long steel bars in four-sided rib high-speed iron steel mesh sheets, and belongs to the field of cold-rolled steel bars. Background technique [0002] With the development of my country's high-speed rail field, the construction of high-speed rail viaducts, the self-compacting concrete layer and base of high-speed rail slab-type trackless tracks all need to use steel mesh. In traditional buildings, the steel mesh is tied manually. With the development of science and technology, At present, the steel mesh used for high-speed rail is welded in the production workshop and directly used in production. Especially in recent years, with the output of high-speed rail technology, the demand for steel bars is also constantly increasing. In view of the high-speed rail Particularity, the steel bars used for high-speed rail are different from those used in general buildi...

AI Technical Summary

Problems solved by technology

[0003] In the production of steel mesh in the past, the special steel bar required in the steel mesh sheet is the long steel bar. In the production, it first needs to be cut according to a certain length, then bundled, and moved to the equipment supply rack by a crane for supply. The steel bars used in the production of mesh sheets will not only affect the straightness of the steel bars during the hoisting and handling process, but also lose the parallelism between each other due to the deformation of the steel bars during the feeding of the steel bars. In the process of feeding or distributing bars, because some steel bars are intertwined with each other, although measures such as vibration and arrangement are used to feed materials, it will still cause alarms and shutdowns of the equipment, which will cause deformation of the equipment. The need to shut down for maintenance directly affects the production of the mesh, especially when the supply time is tight and the production task is heavy. This situation will bring a lot of losses, and even come to the construction site to stop and wait. To prevent this phenomenon from happening, a special person is required to wait beside the feeder to deal with similar situations in time. The longer the steel bar, the more likely this situation will occur
