Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hoisting and carrying, in particular to a hoisting device with a counterweight module. Background Art
[0002] A crane is a multi-action machine that can lift and carry heavy objects vertically and horizontally within a certain range. It is usually called a crane and is divided into traveling cranes and tower cranes according to different places of use. The current cranes mainly include lifting mechanisms, operating mechanisms, luffing mechanisms, slewing mechanisms and metal structures. The lifting mechanism is the basic working mechanism of the crane, which is mostly composed of a hanging system and a winch. There are also hydraulic systems that 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 boom-type cranes. 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 rotate the boom, and is composed of a drive device and a slewing bearing 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. However, most of the current cranes rely on the pulling force of the motor to lift the heavy objects to be hoisted. During the hoisting process, the electrical energy is converted into mechanical energy. Therefore, the traditional crane works at the cost of energy consumption. In order to reduce the loss of energy during the hoisting process, people have invented and produced many cranes with counterweights. For example, counterweights are used in elevators, which saves energy to a certain extent, but it is still not enough. In addition, in order to quickly lift the hoisted objects, the motor of the crane must have the characteristics of high power, which increases the price and cost of the crane. Therefore, some crane users and production personnel hope to have a crane with a simple structure, easy operation, and energy saving to hoist and produce objects, thereby improving the speed and production efficiency of hoisting.
