Embodiment Construction

[0096] figure 1 The assembly of a first embodiment of the invention is shown, comprising a percussion apparatus 2, such as a hydraulic rock breaker, mounted on a conveyor 3, such as a hydraulic excavator.

[0097] The percussion device 2 comprises a stepped striking piston 4 which is optionally slidably mounted within a cylinder 5 arranged within a body 6 of the percussion device 2 . During each working cycle of the percussion device 2 , the beating piston 4 strikes the upper end of a tool 7 slidably mounted in a bore 8 provided in the body 6 coaxially with the cylinder 5 middle. For example, striking piston 4 and cylinder 5 define a lower chamber (not shown in the figures) and an upper chamber (not shown in the figures), said lower chamber being permanently fluidly connected to the A high pressure supply circuit 9 of pressurized incompressible fluid, the more significant section of the upper chamber is arranged above the striking piston 4 .

Abstract

This control method comprises the steps consisting in providing a control device (16) designed to regulate a power supply parameter of a percussion tool (2), providing a control unit (17) designed to apply control setpoint to the control device (16), setting the percussion tool (2) in operation, measuring at least one acoustic data item in the vicinity of a predetermined zone (13), transmitting the at least one acoustic data item measured to the control unit (17), comparing the at least one acoustic data item received by the control unit (17) with a predetermined threshold value, correcting the control setpoint of the control device (16) as a function of the at least one acoustic data item received, and using the control unit (17) to apply said corrected control setpoint to the control device (16).

Description

technical field [0001] The invention relates to a method for controlling power parameters of a percussion device driven by a pressurized incompressible fluid and an assembly for implementing the method. Background technique [0002] Impact equipment known as hydraulic rock breakers are commonly used in a variety of applications, such as breaking rock in quarries, demolition work, or trenching work. The hydraulic rock breaker specifically includes a beating piston configured to cycle the beating tool to generate impact energy on the material to be demolished. When the stone crusher is used, the stone crusher produces excessive operating noise, which is transmitted in the form of sound waves in the surrounding environment of the stone crusher, and may cause noise hazards to people near the stone crusher. [0003] In order to limit the impact of these noise hazards, the use of stone crushers is restricted or even prohibited within a minimum distance around sensitive areas, tha...
