The principle of a wireless remote control grab bucket mainly involves the integration of wireless remote control technology with a mechanical grab system. Here is a detailed explanation of its working principle:
Mechanical Components and Functionality
Structure: The grab system typically comprises mechanical components such as an upper bearing beam, a lower bearing beam, a grab body, a transmission device, and a hydraulic circuit.
Connection and Movement: The upper bearing beam connects the grab body and the transmission device, while the lower bearing beam houses the hydraulic circuit. The grab body is rotatably connected to the lower bearing beam and can be opened and closed through the cooperation of the transmission device and the hydraulic circuit.
Electronically Controlled Components
Emitter and Acceptor: The electronically controlled components consist of an emitter (remote control unit) and an acceptor. The acceptor is connected to the solenoid valve in the hydraulic circuit.
Remote Control: The operator uses the remote control unit (emitter) to send wireless signals to the acceptor. The acceptor receives these signals and converts them into electrical signals to control the solenoid valve.
Hydraulic Circuit and Solenoid Valve
Hydraulic Power: The hydraulic circuit provides the power for opening and closing the grab body. It includes a hydraulic pump, valves, and piping that direct the flow of hydraulic oil.
Solenoid Valve Function: The solenoid valve is a key component in the hydraulic circuit that controls the flow of hydraulic oil. When the solenoid valve receives an electrical signal from the acceptor, it opens or closes to allow or restrict the flow of hydraulic oil, thereby controlling the movement of the grab body.
Power Consumption and Battery Life
Low Power Consumption: Since the solenoid valve does not require electricity for a long time, the power consumption of the wireless remote control grab is relatively low.
Battery Life: The system is equipped with a high-capacity battery that can support operation for an extended period (e.g., 150 hours) without needing to be changed.
