Stall self-locking and jerking prevention device of deep-digging excavator

Abstract

The invention relates to the technical field of excavators, and discloses a stall self-locking and jerking prevention device of a deep-digging excavator. The device comprises a mounting component, anda mounting groove is formed in the mounting component; a first spring mechanism is movably installed in the mounting groove, and the upper end of the first spring mechanism is fixedly connected witha push plate; the upper side of the push plate is fixedly provided with a metal part, and an ejector rod is movably installed in the first spring mechanism; and the upper end of the ejector rod is fixedly connected with the lower side of the push plate. In the fast falling process of an excavator bucket, an electrical metal sheet is powered on, so that an electromagnet is energized and generates huge magnetism; under the effect of centrifugal force, the electromagnet is expanded outwards, and a magnetic ring is expanded outwards simultaneously, and attached to the inner side of the mounting component; since an anti-skid gasket is arranged on the outer side of the magnetic ring, the magnetic ring generates large friction force, so that the device is decelerated through friction to stop; andthus, the effect of reducing the jerking sense during self-locking is achieved.

Description

technical field [0001] The invention belongs to the field of excavators, in particular to a stall self-locking and anti-frustration device for deep digging excavators. Background technique [0002] An excavator, also known as an excavator, is an earthmoving machine that uses a bucket to excavate materials higher or lower than the bearing surface, and loads them into a transport vehicle or unloads them into a stockyard. The materials excavated by an excavator are mainly soil, coal, Sediment and pre-loose soil and rock, from the development of construction machinery in recent years, the development of excavators is relatively fast, and excavators have become one of the most important construction machinery in engineering construction. [0003] Especially in the excavation project, the popularity of using it is very high, but because the excavation project is deep and shallow, if you dig a relatively shallow pit foundation, you need to use more excavators with mechanical arms. ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a stall self-locking and anti-frustration device for deep digging excavators. device, the stall stop effect is poor, resulting in mechanical damage, and there will be a greater sense of frustration when stopping.
