Rotation anti-collision early warning control device of excavator, control device, and excavator

Abstract

The invention discloses a rotation anti-collision early warning control device, a control device and an excavator, and belongs to the technical field of early warning of engineering machinery. The rotation anti-collision early warning control device comprises a controller and a plurality of distance sensors which are respectively connected with the controller, wherein the plurality of distance sensors are distributed at the tail part of a counter weight of the excavator; the controller is connected with a main pump proportional solenoid valve and a pilot operated solenoid valve of the excavator respectively; and specifically, the partition range of the distance from the counter weight to an obstacle behind is judged according to a signal received by the controller, so that the purpose of anti-collision early warning control is realized. The rotation anti-collision early warning control device, the control device and the excavator are available for eliminating vision dead points of an operator of the excavator, realize automatic alarm, and implement related protection action, and an automatic anti-collision monitoring device can be switched manually or automatically; and the rotation anti-collision early warning control device, the control device and the excavator are applicable to severe work conditions, do not cause human misjudgment easily and consequently avoid human injury or property loss.

Description

technical field [0001] The invention relates to the technical field of construction machinery alarms, in particular to a rotary anti-collision early warning control device and method for an excavator and an excavator. Background technique [0002] At present, when medium and large excavators are turning or reversing, the operator of the excavator cannot observe the things behind the counterweight, and can only whistle to signal the attention of the rear personnel. personal injury or property damage. Some excavators on the market are equipped with audible and visual alarm lights at the tail, which automatically emit audible and visual alarms to remind people around to pay attention to safety when the excavator is turning. There are also some high-configuration excavators equipped with video monitoring devices, and the situation behind the excavator can be observed on the display screen in the cab, which is convenient for the excavator operator to operate the excavator accord...

AI Technical Summary

Problems solved by technology

[0004] 1. At present, the operator can only sound the whistle to give an early warning before the excavator moves. If there is a misoperation or forget to sound the whistle, it is easy to cause injury to people and objects. The sound alarm generally uses the alarm buzzer that comes with the excavator. Because the excavator The general working conditions are very bad, and the rear personnel may not notice the alarm sound under the noisy working conditions;

[0005] 2. The video surveillance system installed on some high-configuration excavators is expensive and requires human judgment by the excavator operator, which may easily cause human misjudgment when the excavator is running at high speed
