Description

A kind of hoisting gun carriage with stable docking structure

Technical Field

The utility model relates to the technical field of steel structure hoisting, in particular to a hoisting gun carriage with a stable docking structure.

Background Art

The steel structure hoisting process refers to the process of lifting, hanging and positioning the steel structure components from the ground or other positions through lifting equipment at the construction site. The structural hoisting process refers to the process of lifting, hanging and positioning the steel structure components from the ground or other positions through lifting equipment at the construction site. The steel structure hoisting requires a hoisting trolley, which is widely used in lifting and handling machinery in ports, workshops, construction sites, etc., and is used for hoisting equipment, emergency, lifting, machinery, and rescue. The hoisting trolley mainly includes a lifting mechanism, an operating mechanism, a luffing mechanism, a slewing mechanism, and a metal structure. The lifting mechanism is the basic working mechanism of the crane, which is mostly composed of a hanging system and a winch, and there are also hydraulic systems to lift and lower heavy objects. The operating mechanism is used to move heavy objects longitudinally and horizontally or adjust the working position of the crane. It is generally composed of an electric motor, a reducer, a brake, and wheels. The luffing mechanism is only equipped on a boom crane. The amplitude decreases when the boom is raised and increases when it is bent down. It is divided into balanced luffing and unbalanced luffing. The slewing mechanism is used to make the boom slew, and is composed of a drive device and a slewing support device. The metal structure is the skeleton of the crane. The main load-bearing parts such as the bridge, boom and gantry can be box-shaped structures or truss structures, or web structures. Some can use steel as support beams. There are two types of hoisting gun carriages: movable types: truck cranes, crawler cranes, traveling cranes, etc., and fixed types: dock cranes, tower cranes, gantry cranes, etc.

The docking structure of most existing hoisting gun carriages is generally a simple hook, which lacks a stable docking structure and a block to clamp the docking port of the hook. It cannot stably prevent the heavy objects from falling off the hook, which reduces the efficiency of steel structure hoisting and also brings more safety problems. Therefore, we propose a hoisting gun carriage with a stable docking structure.
