Embodiment Construction

[0027] The specific implementation will be described below in conjunction with the accompanying drawings.

[0028] In the working condition identification and timing system of the construction machinery breaking hammer in the present invention, the construction machinery can be an excavator or a loader. , then the boom of the loader constitutes the installation boom for installing the breaker. In addition to the breaker, other attachments, such as buckets and buckets, can be installed on the boom.

[0029] The breaking hammer is hydraulic type, which includes an impact device for generating impact pulses, a breaking hammer head and a fastening device for connecting with the boom for installing the breaking hammer on the construction machinery.

[0030] The working condition identification and timing system of a breaking hammer of construction machinery includes at least one vibration sensor, a pressure sensor and an induction device.

[0031] The vibration sensor 4 is used t...

Abstract

The invention relates to use identification and timing for use of a breaking hammer in an engineering machine, aims at solving the problem of inaccurate timing for use of a breaking hammer in an engineering machine, and provides an identification and timing system, and an identification and timing method for a working condition using a breaking hammer in an engineering machine. The identification and timing system comprises a vibration sensor for measuring vibration, a main pump pressure sensor, an installation boom movement induction device and a control unit, wherein the control unit receives measurement values of the vibration sensor, the pressure sensor and the induction device, and judges a working state of the engineering machine; and a timer carries out accumulative timing when the engineering machine is under an impact working condition using the breaking hammer. The system disclosed by the invention is simple and reliable, and capable of accurately accumulating a working time of the working condition using the breaking hammer. In addition, only the vibration sensor is added relative to the original machine, thus the cost is basically not increased.

Description

technical field [0001] The invention relates to a system and a method for identifying and timing impact working conditions when a construction machine uses a breaker. Background technique [0002] Breaking hammers are usually attached to construction machinery as attachments for breaking hard materials such as rocks and concrete. The breaker includes an impact device for generating impact pulses, a breaker head and a fastening device for connection with construction machinery such as excavators and loaders. [0003] Since the breaking hammer belongs to the impact working condition, it has a great impact on the installed construction machinery. The manufacturer of the construction machinery host often has to treat the three-guarantee period of the construction machinery using the breaker differently. Therefore, the settings on the construction machinery host can identify the installation on the host. It is very necessary for the timing system of the hammer to perform the imp...
