Safe startup control device and method for engineering machinery auxiliary function

Abstract

The invention discloses a safe startup control device for an engineering machinery auxiliary function. The device comprises a location sensor arranged on a cab seat, a first relay K1 triggered by thelocation sensor, a safe switch S2, a third relay K3 controlled by an auxiliary function switch S1 and a pressure switch S3, wherein the on-off of the pressure switch S3 is controlled through oil outlet pressure of an auxiliary function electromagnetic valve Y. whether a machinist operates in the cab or leaves the cab can be detected through the safe switch and the location sensor, and the relay istriggered to perform different actions according to a detection result, a safe operation aim can be achieved by only needing one workers, the manpower cost is saved, and the safety operation aim is achieved; the cost is low, the realization is easy, and the good safe operation aim can be achieved.

Description

technical field [0001] The invention relates to the field of pile construction and construction machinery, in particular to a device equipped with an auxiliary function device that needs to be operated outside the driver's cab. Background technique [0002] Due to the danger during the construction of construction machinery, the operator is required not to leave the cab, so as to ensure the monitoring and operation of the construction action at any time. Once leaving, all construction actions must be stopped and the corresponding safety switch must be turned off at the same time. At the same time, some auxiliary functions such as cleaning, oil filling, etc. need to get off the car to operate. In this way, it is necessary to judge whether the operation is in the cab or under the vehicle, so as to make the correct switch and achieve the purpose of safety protection. [0003] At present, the operator usually does not leave the cab, and when auxiliary actions need to be operate...

AI Technical Summary

Problems solved by technology

[0004] The operator does not leave the cab, and the auxiliary function of staff operation can achieve the purpose of safe operation, but it needs to add more than one staff, resulting in a waste of personnel; directly getting off the car and operating without safety switching will bring inconvenience to the operation. Potential safety hazard. It is a potential safety hazard to operate auxiliary actions during construction or to be able to control construction actions while operating auxiliary actions.
