U-shaped steel bar storage device and storage and hoisting method

Abstract

The invention provides a U-shaped steel bar storage device and a storage and hoisting method, and belongs to the technical field of high-speed railway box girder steel bar finished product storage. The U-shaped steel bar storage device comprises a left frame, a middle frame, a right frame, a bottom support and a lateral supporting beam; each of the left frame and the right frame comprises a side bottom frame and a supporting beam mounting frame; the side bottom frames of the left frame and the right frame are located on the two transverse sides of the middle frame and detachably connected with the middle frame. A lifting ring is arranged on the supporting beam mounting frame; bottom supports are fixed to the side bottom frames and / or the middle frame, each set of bottom supports comprises a plurality of bottom supporting columns, and bottom clamping grooves are vertically formed in the bottom supporting columns. Each side frame is provided with an upper clamping groove and a lower clamping groove, the lateral supporting beams are installed in the upper clamping grooves or the lower clamping grooves, and lateral clamping grooves are formed in the two lateral supporting beams. According to the method, the management steps of products are simplified, the sorting labor capacity of workers is saved, the joist barrow and the U-shaped steel bar lifting appliance are combined, batch storage, transferring, lifting and placing of the U-shaped steel bars are achieved, and the manufacturing speed of the box girder framework is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of high-speed railway box girder steel bar product storage, and in particular relates to a U-shaped steel bar storage device and a storage and hoisting method. Background technique [0002] The U-shaped steel bar used in the construction of high-speed railway box girder can be up to 4 types in total according to the difference of standard section and variable-end section, single-line beam and double-line beam, namely U-shaped steel bar of single-line beam standard section, single-line beam The U-shaped steel bar of the beam variable end section, the U-shaped steel bar of the double-line beam standard section section, and the U-shaped steel bar of the double-line beam variable end section section. Each type of rebar is usually scattered and staggered in the storage area after being processed and formed. When starting to process the rebar frame of the box girder, workers need to laboriously sort out the finish...

Problems solved by technology

[0003] The purpose of the present invention is to provide a U-shaped steel bar storage device and storage and hoisting method, which can effectively solve the problem of 4 kinds of U-shaped steel bars (U-shaped steel bars in the standard section section of single-line beams, U-shaped steel bars in variable-end section sections of single-line beams, etc.) The U-shaped steel bars in the standard section section of double-line beams and the U-shaped steel bars in the variable-end section of double-line beams) are scattered and stored and transported and arranged one by one, resulting in a large demand for engineering labor, low operating efficiency, cumbersome management of finished U-shaped steel bars, and all The number of storage devices is large, the storage density of the devices is small, the storage area occupies a large area, and the technical problems are difficult to operate
