Description
Technical Field
The invention relates to the technical field of a heading machine, in particular to a cutting big arm of a cantilever type heading machine and the heading machine.
Background
The boom-type roadheader is widely applied to mining operations of coal mine tunnels, mountain tunnels and the like and mainly comprises a cutting mechanism, a traveling mechanism, a transfer mechanism and other main mechanisms. During the mining and charging processes, the boom-type roadheader needs to advance and retreat frequently, which seriously reduces the mining efficiency of the roadheader and will damage the service life of a chassis mechanism of the roadheader. In order to avoid these situations, corresponding telescopic devices are usually designed on the cutting mechanism of the heading machine, so that the mining rate of the coal mine tunnel is greatly improved. The conventional boom-type roadheader mainly has two cutting and telescoping modes. Firstly, a telescopic device is arranged on a cantilever section between a cutting motor and a cutting head; the other type is that the cutting motor, the cutting speed reducer and the cutting head are connected into a whole, and a telescopic device is arranged between the whole part and the cutting large arm structural member. In either way, the cutting mechanism is telescopic along the axial direction of the cantilever.
When the telescopic device is arranged in the cutting part or the motor box body, the cutting head and the cutting speed reducer are driven by the telescopic oil cylinder to integrally move, the structure of the cutting large arm is complex due to the layout, and the working difficulty during maintenance and inspection is increased. In addition, when the working conditions of semi-coal rocks and rocks are met, the cutting part shakes violently during cutting, the stability of the connection between the telescopic device and the main body is influenced, and the service life of the telescopic device is further influenced. In addition, most of the existing roadheader is formed by connecting a cutting head, a cutting speed reducer and a cutting motor into a whole, and a telescopic device is arranged between the whole part and a cutting large arm structural member. However, the extension range of the extension devices is low, which also limits the mining efficiency of the heading machine, thereby affecting the construction period and the construction progress.
