Emergency system for engineering machinery after failure of hydraulic system

Abstract

The invention discloses an emergency system for an engineering machinery after the failure of a hydraulic system. An active power device provides high-pressure oil liquid to a hydraulic device; a hydraulic pipeline comprises an oil inlet pipe and an oil discharge pipe; emergency pipes are laterally connected onto the oil inlet pipe and the oil discharge pipe through three-way connectors; quick-change connectors are arranged on the end parts of the two emergency pipes; the system is provided with an emergency power device; hydraulic rubber pipes are connected to an oil outlet and an oil inlet of the emergency power device; and connector structures matched with the quick-change connectors are arranged on the end heads of the two hydraulic rubber pipes. The emergency system for the engineering machinery after the failure of the hydraulic system provided by the invention has the advantages that an original hydraulic system of the engineering machinery can ensure the safety and the reliability of equipment operation, and if the system is applied onto a crane of the company, the occurrence of the phenomenon that the normal operation of a production line of a four steel rolling plant is influenced due to the repeatedly breakdown of the crane is avoided. A method provided by the invention is applied to a dumper of the company, so that break-down loaded cars incapable of driving in theworking site are ensured to be returned to the headquarter so as to be repaired after being unloaded. The emergency system for the engineering machinery after the failure of the hydraulic system is remarkable in effect and higher in practical value.

Description

technical field [0001] The invention relates to the field of engineering machinery. Background technique [0002] Current construction machinery such as loaders, excavators, bucket trucks, dump trucks, etc. If the hydraulic system itself or its power part fails during use, it will not only be unable to implement normal production operations, but also cannot be quickly repaired in the on-site environment, and in many cases, the trailer operation will not be able to be carried out, resulting in production line shutdown or accidents. Contents of the invention [0003] The technical problem to be solved by the present invention is to realize that when the hydraulic system itself or its power part of a construction machine fails during use, the application of the present invention can restore the function of the hydraulic system in a short time, so that the faulty vehicle can quickly drive away or be caught. Tow away from the job site to ensure the normal operation of the prod...
