Abstract

The invention relates to the technical field of electrical hoists and in particular relates to an elasticity adjusting device for a rope guider of an electrical hoist. The elasticity adjusting device comprises a plurality of rope guide blocks and a plurality of springs, wherein an upper limiting plate and a lower limiting plate are fixedly arranged on one rope guide block and integrated with the rope guide block; grooves are symmetrically formed in the two ends of each rope guide block, and buffer cushions are fixedly connected to the two end surfaces of the rope guide block; through holes are formed in the buffer cushions; the middle section of each spring is embedded into each through hole, the two ends of the spring are arranged in the grooves, connecting blocks are fixedly connected to the two ends of the spring and have T-shaped cross sections, and one end of each connecting block is fixed to the bottom surface of each groove through a screw. When the elasticity adjusting device is used, the springs can guarantee the circular shape of the rope guider in a tightening process, so that the problem of groove jumping of a steel wire rope due to wear of the rope guide blocks is solved. The elasticity adjusting device has the advantages of simple structure, reasonable arrangement, low manufacturing cost and the like.

Description

technical field [0001] The invention relates to the technical field of electric hoist, in particular to an electric hoist rope guide with a tightness adjusting device. Background technique [0002] Electric hoist is a kind of special lifting equipment, which is installed on the crane and gantry crane. The electric hoist has the characteristics of small size, light weight, simple operation and convenient use. It is used in industrial and mining enterprises, storage docks and other places. [0003] The existing electric hoist rope guide will be worn after long-term use, and the steel wire rope will skip jobs, making the rope guide invalid. In order to solve this problem, a lot of meaningful exploration work has been done in the industry. Such as existing patent No. is 200920140423.8, title is called: electric hoist rope guide, it adopts a coupling mechanism with a band spring to automatically adjust the tension of the rope guide. As we all know, the rope guide has a circular...
