Document Type and Number:
WIPO Patent Application WO/2023/116387
Kind Code:
A1
Abstract:
Provided in the present application are an emergency apparatus for operation machinery, and a fire-fighting truck. The emergency apparatus comprises an emergency power source expansion interface and a signal control apparatus, wherein after an electric connection between the emergency power source expansion interface and an emergency power source is established, the emergency power source is connected to an electric control circuit of operation machinery, so as to supply power to a main controller and an emergency switching valve of the operation machinery; the main controller receives a driving signal for a target element in the operation machinery that is sent by a signal control apparatus; and the main controller controls, in response to the driving signal, an action state of a control valve for supplying power to the target element, and controls the emergency switching valve to adjust a conduction state of a hydraulic oil circuit of the target element. By means of the emergency apparatus for operation machinery, and the fire-fighting truck provided in the present application, an external emergency power source can be connected to an electric control circuit of operation machinery by using an emergency power source expansion interface, such that electric control over some key fire-fighting elements in an emergency state can be realized; and a user can perform an emergency operation by means of a signal control apparatus, such that an operation process is effectively simplified, the emergency response time is shortened and operation risks are avoided.
