Highway pavement joint cutting equipment

LIU YONG

The invention relates to the field of engineering construction and especially relates to highway pavement joint cutting equipment. The equipment comprises a cutting mechanism, a cutting transmission mechanism, and a cleaning driving mechanism, wherein the cutting mechanism is arranged on a side portion of a cart and includes a first cutting saw blade disc and a second cutting wheel; the first cutting saw blade disc is used for cutting a pavement; the second cutting wheel is positioned on a front side of the first cutting saw blade disc; the cutting transmission mechanism is arranged on the side of the cutting mechanism and is used for driving the first cutting saw blade disc and the second cutting wheel to carry out cutting work, and driving the second cutting wheel to be in a contact or non-contact state with the pavement; and the cleaning driving mechanism is arranged on the cart, an output end of the cleaning driving mechanism is in transmission connection with the cutting transmission mechanism, a working state is used for switching and the working state includes a cutting state or a static state. In the invention, whether the second cutting wheel makes contact with the pavement or not is controlled through the cutting transmission mechanism, residual substances at corners of the pavement are treated in advance when the second cutting wheel makes contact with the pavement,and a cutting effect of a cutting blade is improved.

本发明涉及工程施工领域，具体是涉及一种公路路面切缝设备，包括切割机构，设置在推车的侧部，包括第一切割锯片盘和第二切割轮，第一切割锯片盘用于切割路面，第二切割轮位于第一切割锯片盘的前侧，切割传动机构，设置在切割机构的侧部，用于驱动第一切割锯片盘和第二切割轮进行切割工作，以及驱动第二切割轮与路面处于接触或者非接触状态，清理驱动机构，设置在推车上，清理驱动机构的输出端传动连接有切割传动机构，用于切换的工作状态，工作状态包括切割状态或者静止状态，本发明通过切割传动机构控制第二切割轮是否与路面接触，第二切割轮与路面接触时预先对路面拐角处残留物质进行处理，提高切割片切割效果。
