A Six-bar Twelve-pair Excavating Mechanism Working at Multiple Angles

Abstract

Provided is a six-rod and twelve-pair excavating mechanism working at many angles. The lower end of a first rod of the mechanism is connected to a working platform and the upper end of the first rod is connected to a first sliding sleeve. A second rod is sleeved with the first sliding sleeve, one end of the second rod is connected to an actuator, and the other end of the second rod is connected with the upper end of a first telescopic rod. The lower end of the first telescopic rod is connected to a sliding block installed in a sliding groove in the working platform. The lower end of a second telescopic rod is connected to the working platform, and the upper end of the second telescopic rod is connected to a second sliding sleeve. The first rod is sleeved with the second sliding sleeve. The lower end of a third rod is connected to the working platform, and the other end of the third rod is connected with the first corner of a triangular connection board. One end of a third telescopic rod is connected to the second corner of the triangular connection board, the other end of the third telescopic rod is connected to the actuator, and the third corner of the triangular connection board is connected with the first telescopic rod and the second rod. The six-rod and twelve-pair excavating mechanism working at many angles has the advantages of large working space, high digging force and good stress of a traditional hydraulic press mechanism, reduces the number of driving rods and controllable motors, and reduces complexity of a rack transmission system.

Description

technical field

[0001] The invention relates to the field of machinery, in particular to a six-rod twelve-pair excavating mechanism working at multiple angles. Background technique

[0002] Excavator is a kind of common construction machinery, which is mainly used in various engineering operations. Among them, the hydraulic excavator is a type of excavator widely used at present, but the hydraulic excavator has problems such as high manufacturing cost of the hydraulic system and prone to oil leakage. However, traditional single-degree-of-freedom mechanical excavators, commonly known as "electric shovels", can only achieve simple and unchangeable trajectory output, so they cannot be used in a wide range of fields like hydraulic excavators.

[0003] With the development of motor technology and the improvement of control technology, the controllable mechanism provides a broad development space for construction machinery. The multi-degree-of-freedom controllable mechanism drive...
