Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example (b):

as shown in fig. 1-4, an overturn preventing device for installing a base hook comprises a supporting plate 1 and a hook fixing seat 2 arranged on the supporting plate 1, wherein the hook fixing seat 2 is used for fixing a base hook 3, and the hook fixing seat 2 and the supporting plate 1 are both made of S316 stainless steel, so as to prevent the hook from being corroded due to the contact with the base hook 3. The supporting plate is provided with a fixed seat accommodating hole, and the hook head fixed seat 2 is arranged in the fixed seat accommodating hole; the periphery of the supporting plate 1 is provided with a guardrail 4, and the guardrail 4 is provided with an anti-collision barrier 5 to prevent the tool from colliding and damaging the hook head in the hoisting process. The upper end of guardrail 4 is equipped with lug 6, facilitates the use chain sling and fixes the frock on base davit 7 and hangs the common transportation to treating the installation region along with the base. Be equipped with cat ladder 8 on the guardrail 4, cat ladder 8 makes things convenient for gib head 3 workman's entering frock to assist when threading wire rope and carries out the wire rope handling work. The lower extreme of layer board 1 is equipped with support footing 9, the lower extreme of support footing 9 is equipped with the bolt hole, can use the bolt to fix the frock on the module in gib head 3 installation, prevents that the frock from producing to slide and influence installation work.
