Four-degree-of-freedom multi-layer parallel lifting mechanism of clamp car

Abstract

A four-degree-of-freedom multilayer parallel lifting mechanism for a clamp car mainly comprises bases A, adjustment oil cylinders, hinges A, supporting beams, spherical hinges A, bases B, forcipated beams, hinges B, spherical hinges B, lifting oil cylinders, spherical hinges C and a tray. The inner sides, at the two sides of goods, of the four-degree-of-freedom multilayer parallel lifting mechanism are opposite with the center line of the goods as the symmetry axis. According to the four-degree-of-freedom multilayer parallel lifting mechanism for the clamp car, the load capacity of the lifting mechanism is effectively improved, and the lifting mechanism can be used for lifting and transporting super-heavy goods; the work space of the lifting mechanism is effectively increased, the influence of unbalanced loading of the goods on the lifting mechanism is reduced, and the lifting mechanism can be used for transporting super-wide goods; due to the fact that a multi-drive coordinative working mode is adopted, the lifting mechanism can be used for loading and unloading goods more conveniently and more flexibly.

Description

technical field [0001] The invention relates to a four-degree-of-freedom multi-layer parallel over-constraint lifting mechanism. Background technique [0002] With the promotion of industrial upgrading and the implementation of energy-saving and emission-reduction strategic measures in China, UHV transformers, large-scale generators and other complete sets of ultra-high-power electrical appliances will be developed in the future. The weight of these large-scale energy equipment will reach nearly 1,000 tons. In order to ensure the safety of these special cargoes, higher requirements are put forward for the safety and reliability of its transport clamp vehicles. With the development of the above-mentioned special cargo transportation demand, domestic and foreign clamping vehicle technology is developing towards large-scale, ultra-high load, high safety and reliability. Therefore, it has become an urgent need in the field of railway transportation in my country to develop clam...

AI Technical Summary

Problems solved by technology

There are few domestic and foreign patents on clamping vehicles, among which there are fewer patents involving lifting mechanisms. For example, the technology disclosed in Chinese patent CN101475007A, which improves the weight of the vehicle by changing the self-supporting structure of the clamping vehicle, reducing the center of gravity of the vehicle and the quality of the whole vehicle. The load capacity of the whole vehicle and the convenience of transportation, but due to the limitation of the configuration, this technology is not suitable for the transportation of super-heavy and super-wide cargo; the technology disclosed in Chinese patent CN103101546A, which coordinates the work of the lifting cylinder of the clamping car The synchronization rate of the goods is improved to improve the stress of the clamping vehicle during the lifting process of the goods, but it does not reduce the working pressure of the lifting cylinder during the lifting process, and it is also not suitable for the transportation of super-heavy goods; the technology disclosed in Chinese patent CN104192155A, its By changing the driving configuration of the lifting mechanism, the load of the lifting cylinder during the lifting process is effectively reduced, but there are still certain application limitations for the lifting of super-heavy loads and ultra-wide cargo
