Anti-rotating positioning device for crane hook

Abstract

The invention discloses an anti-rotating positioning device for a crane hook. The anti-rotating positioning device comprises a pulley assembly, two hoisting yoke plates, and a suspension hook assembly; the suspension hook assembly comprises a suspension hook, a crossbeam, a positioning nut and an anti-off bolt; the middle of the crossbeam is penetrated vertically by the upper end of the suspension hook; the positioning nut and the upper end of the suspension hook are connected via threaded connection; the positioning nut and the upper end of the suspension hook are penetrated by the anti-off bolt transversely; the suspension hook and the positioning nut are arranged on the crossbeam via a bearing; the middle of one side of the crossbeam is provided with a suspension hook anti-rotating positioning mechanism comprising a sleeve, a positioning sleeve head, a plug pin, a spring, a locating pin and a handle block; the sleeve is fixedly arranged on one side of the crossbeam; the positioning sleeve head is fixedly arranged on the outer end of the sleeve; the positioning sleeve head and the sleeve are penetrated by the inner end of the plug pin, and the inner end protrudes into a positioning hole arranged at the upper end of the suspension hook; the two ends of the spring are pressed against the inner end of the plug pin and the positioning sleeve head respectively; the outer end of the plug pin is transversely penetrated by the locating pin, and the inner part of the positioning sleeve is pressed against by the locating pin. The anti-rotating positioning device is suitable for hanged transporting under normal working conditions, and under space limited conditions; can be used for hanged transporting of special objects, such as high-temperature objects, and objects that are easy to corrode; and is safe and reliable for suspension hook positioning.

Description

technical field [0001] The invention relates to a crane hook, in particular to a crane hook anti-rotation positioning device, which belongs to the technical field of lifting equipment. Background technique [0002] There are two kinds of hook sets of the crane, the traditional type and the anchor hook type. The traditional type of hook set often causes the hook head and The heavy object keeps swinging or rotating for a long time, which is prone to bumping and unnecessary losses, especially when lifting special items such as high temperature and corrosion, there are still great potential safety hazards. Although the anchor hook group The above-mentioned problems do not exist, but it has high requirements for the placement of lifting objects and is inconvenient to operate. Contents of the invention [0003] The object of the present invention is to provide a crane hook anti-rotation positioning device which has simple structure, convenient operation and can effectively pre...
