Referring to fig. 2 to 7, an embodiment of the present application provides an on-site screening method using the on-site screening apparatus 1 in any of the above embodiments, including the following steps: and a packing step of packing the plurality of net rack rods 20 together by using a packing belt 21 to obtain a packed piece 2. Separating step, placing the packing members 2 on the second frame 101, and disconnecting the packing belts 21 so that the respective net rack bars 20 move and arrange on the bar separating frame 10 under the action of gravity. A selection step of selecting desired rack bars 20 from the arranged rack bars 20, so as to realize the on-site screening of the rack bars 20.
The packing step may include the steps of: numbering substeps, numbering each rack bar 20. And a packaging sub-step of packaging the numbered rack rods 20 together by using a packaging belt 21 to obtain a packaged part 2, numbering the packaged part 2, and recording the numbers of the rack rods 20, which is shown in fig. 4-5.
The packaging step may be done at the manufacturing facility. In the packing step, the outside of each rack rod piece 20 can all be wrapped up with bubble film plastics, prevents that rack rod piece 20 from packing and the paint destroys in the transportation. Because each rack bar 20 varies in length, diameter, and angle of erection, each rack bar 20 needs to be uniquely numbered. In the packing member 2, the packing belts 21 may be located at both ends of the net frame bar 20. In the packing element 2, the rack bars 20 may be stacked in a triangular pile. The resulting packaging list (shipped to the site simultaneously with package 2) may be specified as follows:
|
|
Packaging member X |
Net rack rod number XXa1 | Net rack rod number XXb1 | Net rack bar number XXX1 |
Net rack rod number XXa2 | Net rack rod number XXb2 | Net rack bar number XXX2 |
Net rack rod number XXa3 | Net rack rod number XXb3 | Net rack bar number XXX3 |
Rack bar number … …. | Number … … of net rack rod | Number … … of net rack rod |
It should be noted that the high-strength bolts at both ends of each rack bar 20 are screw-mounted with the protection caps 22.
The separating step may comprise the steps of: the positioning sub-step, placing the packing element 2 on the second frame 101, and tightening the buffer strip 13 on the outside of the packing element 2. The sub-step of separation, breaking the strapping band 21 and loosening the buffer band 13, allows each rack bar 20 to move and align slowly on the bar-separating rack 10 under the action of gravity and the constraint of the buffer band 13, see fig. 6-7.
In the separation step, the packing member 2 may be lifted onto the second frame 101 by a crane or a forklift. The buffer belt 13 can be tightened against the outside of the bale 2 by means of a hoisting machine 14. The strapping band 21 may be cut off. The strapping band 21 can be gradually released from the buffer band 13 by the hoist 14.
When more rack bars 20 are needed, more rack bars 20 in a pack 2 can be separated and selected, which will not be described in detail. The field screening method solves the problems that manpower is split and then the manual split and the manual split are carried and arranged one by one to select and sort in the traditional method, and a large amount of manpower resources and repetitive labor need to be invested.
