Space-controllable mechanism type loader

Abstract

A space-controllable mechanism type loader comprises a traveling device, a stander, a large arm, an upper support chain, a lower support chain and a bucket, wherein the stander is mounted on the traveling device; the large arm is hinged onto the stander; the bucket is hinged to the other end of the large arm; one end of the upper support chain and one end of the lower support chain are respectively connected onto the stander; the other ends of the upper support chain and the lower support chain are respectively connected with the bucket; and the upper support chain and the lower support chain are respectively driven by a servo motor mounted on the stander and are mutually matched to finish the loading operation. According to the space-controllable mechanism type loader, the defects of a hydraulic loader, that the requirement on the manufacturing precision of a hydraulic element is high, hydraulic oil is serious influenced by the temperature, a hydraulic system has faults which are not easy to check and eliminate and the like can be overcome; in addition, compared with other controllable mechanism type loaders, the space-controllable mechanism type loader has the advantages that the bucket can be inclined and rolls over within a certain range; the finish of the construction on the inclined work surface is facilitated; high flexibility is obtained; and the space-controllable mechanism type loader is especially suitable for manufacturing large-size high-flexibility loaders.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a space-controllable mechanism loader. Background technique [0002] Loader is a kind of earthwork construction machine widely used in highway, railway, construction, hydropower and other construction projects. It is mainly used for shoveling bulk materials such as soil, sand and gravel, and can also be used for light shoveling of ore and hard soil. Operation. Different auxiliary working devices can also be used for bulldozing, lifting and loading and unloading of other materials. Hydraulic loaders are the most widely used type of loaders, but the maintenance of the hydraulic system is complicated, the cost is high, and the hydraulic system is easily affected by environmental factors, especially in low or high temperature environments, prone to weakness or vibration. [0003] With the development of numerical control technology and the improvement of the mechanical industry...

AI Technical Summary

Problems solved by technology

The current loader bucket can basically only rise and fall flat, and cannot do some spatial movements. For example, it cannot rotate at a certain angle in the horizontal plane, nor can it tilt at an angle in the vertical plane. Therefore, in some construction situations, the traditional loader is obviously How to reduce the number and weight of the connecting rods in the mechanism and make the bucket do some spatial movements under the premise of ensuring the task has become a problem discussed by many scholars and institutions.
