One kind in material, using the material with certain fire resisting and heat-proof quality, improve the fire protecting performance of zip.
9th, preferable, the internal lining pipe (2) is installed using snap-fit attachment, and the outer liner tube (4) is using the company of fastening
Connect, a kind of mounting means in flange connection or steel band colligation connection, simple in construction, convenient disassembly, improve and change efficiency.
Preferably, internal lining pipe (2) and outer liner tube (4) are tubular, and intensity is high, and connection is reliable.
Present invention also offers a kind of preparation method of Ha Fushi Novel fireproofs drag-line, it is characterised in that：Including following step
Suddenly：
Step 1. places two semi-circular tubes of internal lining pipe (2) in the outside of drag-line (1), and institute is installed using snap-fit attachment
State two semi-circular tubes of internal lining pipe (2)；
Step 2. fireproof material layer (3) outside two semi-circular tubes for placing outer liner tube (4), using be fastened and connected, method
Orchid connection or two semi-circular tubes of steel band colligation connection outer liner tube (4)；
Step 3. irrigates fire proofing material between internal lining pipe (2) and outer liner tube (4), forms fireproof material layer (3).
Beneficial effects of the present invention：
It is simple in construction using detachable fire proof construction, on the basis of stayed structure and function is not influenceed, it is not necessary to
Drag-line is dismantled, under the operating mode of drag-line normal use, it is only necessary to remove internal lining pipe and outer liner tube achieves that the dismounting of fireprotection layer
Change, replacing options are simple, can independently carry out the installation and replacing of drag-line fire proof construction, while do not influence normally making for drag-line again
With.
