Abstract

The invention belongs to a crane apparatus, and in particular relates to a screwing-in anchoring device for a crane which is suitable for the nuclear power with high safety requirements. The screwing-in anchoring device is characterized in that a trolley frame of the crane is equipped with the screwing-in anchoring device consisting of a supporting plate, a mark A, a mark B, a hollow screw rod, a guide cone head, an inner screw rod, a small nut, a big nut, a square locking block, a locking bush and a guide cone. The screwing-in anchoring device is scientific and rational in design and compact in structure, can realize the anchoring of a vertical direction while holding the anchoring in a horizontal direction, is not only suitable for the protection in earthquake, but also suitable for preventing the invasion of sudden wind; and the screwing-in anchoring device has the advantages of convenience in operation, firmness in anchoring, low fault rate, safety in operation and convenience in use.

Description

technical field [0001] The invention belongs to crane equipment, in particular to a screw-in anchoring device for cranes suitable for cranes with high safety requirements such as nuclear power plants. Background technique [0002] At present, the cranes used in ports or outdoors are usually protected by installing traditional anchoring devices on the cranes; the traditional anchoring devices are divided into pin type, chain type, and push rod type. and anchor plate type, etc., and most of their structures adopt a lever structure; after patent retrieval, its patent announcement number is an anchor device of CN200910181447.2, and its structure includes a lever handle, a rotating pin shaft, a labor-saving counterweight, and an anchor plate and locking holes. The above-mentioned traditional type of anchoring device has the following disadvantages and deficiencies: it can only achieve anchoring in the horizontal direction, but cannot achieve anchoring in the vertical direction. ...
