Problems solved by technology

[0003] Because different hydraulic breakers have different pressure requirements and flow requirements for hydraulic sources, traditional excavators often need to change the electronic control program when replacing the breaker. After purchasing a new hydraulic breaker, users cannot replace it by themselves. , but it is inconvenient to ask the supplier of the hydraulic hammer to send technicians to the door for debugging, and it also leads to an increase in the service cost of the hydraulic hammer supplier

Embodiment 1

[0018] Embodiment 1: Referring to accompanying drawings 1 to 4, a hydraulic excavator breaker parameter setting method, in the control device of the excavator, a breaker parameter setter is provided, and the breaker parameter setter includes For the preset parameter database, input module, display module and setting module, first select the preset breaker brand and model, after confirming the parameters, the setting module modifies the memory of the electric control program of the excavator, and completes the parameter setting of the breaker. The above parameters include the hydraulic system pressure, flow and matching power of the hydraulic pump. In this example, 8 internationally renowned suppliers of hydraulic breakers with relatively large market share are selected: SANY in China, Krupp in Germany, Stanley in the United States, Rammer in Finland, Atlas in Sweden, Montabert in France, Furukawa in Japan, Soosan in South Korea and other brands and their suppliers. The specifi...

Embodiment 2

[0021] Embodiment 2: A method for setting parameters of a hydraulic excavator breaker. In the control device of the excavator, a breaker parameter setter is provided. The breaker parameter setter includes a preset parameter database, an input module, a display module and In the setting module, first select the preset breaker brand and model. After confirming the parameters, the setting module modifies the memory of the electric control program of the excavator to complete the parameter setting of the breaker. The parameters include the pressure, flow and hydraulic pressure of the hydraulic system. Matching power of the pump.

[0022] Wherein, in the step of confirming parameters, the displayed data can be modified.

[0023] After installing a new breaker, enter the setting program, first select the brand of the breaker, and then select the model, according to the selected brand and model, the corresponding parameters will be displayed for confirmation, after confirmation, the ...

Abstract

The invention discloses a hydraulic excavator hammer parameter setting method, characterized in that: in an excavator controller, setting a hammer parameter setter which comprises preset parameter database, input module, display module and setting module, firstly selecting preset hammer trademark and model, after confirming parameters, modifying excavator electric control program memory by the setting module and completing settings of the hammer parameters including pressure and flow of hydraulic system and matching power of hydraulic pump. And the invention implements 'plug-and-play' function of the hydraulic hammer, and when a user changes the hydraulic hammer, he only needs to select the corresponding trademark and model on display screen to be able to implement power system's power, pressure and flow matching.

Description

technical field [0001] The invention relates to a breaking hammer used in conjunction with a hydraulic excavator, in particular to a method for setting parameters of the hydraulic excavator when using the breaking hammer. Background technique [0002] Hydraulic breakers are widely used in engineering fields such as rock crushing, tunnel excavation, demolition of roads, bridges and buildings, and crushing of asphalt or concrete pavement. Its main component—the hydraulic impactor is composed of a cylinder, an impact piston, a control valve and an accumulator. Using the pressure difference between the front and rear chambers of the piston, the piston reciprocates at high speed and impacts the work object to do work. The hydraulic breaker can be installed on the excavator, and the hydraulic system of the excavator is used as the hydraulic source for its work. Usually, a spare valve for connecting with the breaker is set on the hydraulic pipeline of the excavator, and the control...
