Light anti-swing lifter and lifting mechanism thereof

Abstract

The invention provides a light anti-swing lifter and a lifting mechanism thereof. The light anti-swing lifter comprises a moving part movably arranged on a fixed cross beam, and a lifting hook suspended below the moving part through a rope, wherein at least one guide channel is formed in the moving part in the vertical direction, and anti-swing straight rods are slidably connected into the guide channels. The guide channels perform transverse limitation on the anti-swing straight rods, then the transverse movement of the lifting hook is limited, and the stability of goods in the conveying process is guaranteed. Compared with a multi-stage telescopic structure in the prior art, even if the anti-swing straight rods retract upwards to the maximum degree, a structural length influencing further ascending of the lifting hook can exist; in the light anti-swing lifter, the bottom ends of the anti-swing straight rods are fixed to the lifting hook, the whole anti-swing straight rods slide along the guide channels, and the whole anti-swing straight rods are used as a guide path to fully guarantee the lifting range of the lifting hook; and meanwhile, only the fit tolerance of the anti-swing straight rods and the guide channels exists, and thus it can be fully avoided that the anti-swing straight rods swing due to multi-stage fit tolerance.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a light anti-swing lifter and its lifting mechanism. Background technique [0002] As a mechanical equipment for material handling, loading and unloading or installation, cranes can reduce or replace people's physical labor and improve labor productivity. It is widely used in various fields of the national economy, in metallurgical industry, machinery manufacturing industry, electric power industry , coal industry, transportation industry, construction industry, building materials industry and other pillar industries of the national economy, lifting and transportation machinery all play an important role. With the development of the times, manufacturing plants and loading and unloading workplaces began to turn indoors, making the door type Cranes occupy a dominant position. Gantry cranes are mainly used in large-scale processing enterprises, such as steel, metallurgy and building materials ...

[0002] As a mechanical equipment for material handling, loading and unloading or installation, cranes can reduce or replace people's physical labor and improve labor productivity. It is widely used in various fields of the national economy, in metallurgical industry, machinery manufacturing industry, electric power industry , coal industry, transportation industry, construction industry, building materials industry and other pillar industries of the national economy, lifting and transportation machinery all play an important role. With the development of the times, manufacturing plants and loading and unloading workplaces began to turn indoors, making the door type Cranes occupy a dominant position. Gantry cranes are mainly used in large-scale processing enterprises, such as steel, metallurgy and building materials industries, to complete the lifting and hoisting work in the production process. However, most of the cargo hoisting process is hoisting with flexible ropes. Serious, causing great safety hazard

[0003] Patent document CN211769838U discloses an anti-swing and anti-shock assembly crane. The swing range of the load is effectively reduced by the telescopic rod device, and the anti-sway guide wheel frame moves left and right with the hoist trolley assembly, and the guide wheel contacts the bottom of the main girder of the crane under force. , to prevent the swing of multi-stage telescopic rods, mobile platforms and heavy objects, but the joints of multi-stage telescopic rods are likely to be damaged during the process of limiting the swing, shortening their service life
