Description
Technical field
The present invention relates to a kind of digging equipment field, the combined type that especially a kind of vibratory impulse adds water jet auxiliary to cut is broken
Coal mechanism.
Background technique
In coal industry programmatic document《About several opinions for promoting coal industry to develop in a healthy way》In, in national coal
In industrial science technology conference and in the coal industry the policy of construction adjustment of National Development and Reform Committee's appearance, it is large-scale to be directed to development
The contents such as coal underground performing comprehensive coal mining equipment.Driving and back production are the important production links of coal production, and national policy is：It adopts
Pick is laid equal stress on, and driving is leading.The speedy drivage of coal mine roadway is the key measures that coal mine guarantees mine stable high yield.Efficient machine
Toolization driving is to guarantee that mine realizes the developing direction of one of necessary condition of high-yield and high-efficiency and tunnelling technology.China
Most important road heading machinery is boom-type roadheader in coal road high efficient driving mode.Boom-type roadheader is collection cutting, shipment, row
It the functions such as walks, operate in one, being mainly used for the Rock in Well, coal or alternate heading of cutting arbitrary shape section.Present state
Interior development machine design is able to satisfy domestic demand substantially, but from international advanced technology there are also with a certain distance from.And domestic current rock
Lane is constructed still based on drilling and blasting method, and driving of the heavy boom-type roadheader for large rock-gateway is under test in China.
That there are safeties is low for big gun pick technology, tunnel it is secondary destroy, dust is big, driving speed is slow, the length of service is short, maintenance cost is high etc. asks
Topic.Therefore, the boom-type roadheader that can be competent at cutting hard rock is badly in need of technological innovation.Cutterhead is the execution unit of development machine,
Its performance superiority and inferiority, directly determines the economic benefit of coal mining.In order to accelerate the localization process of high efficient driving equipment, improve
It is imperative to carry out structure design to cutterhead for coal petrography cutting efficiency.
Overhang portion section boring machine is mainly used for coal road and alternate heading driving, flexible working mode, to tunnel
Shape and coal petrography preservation situation strong applicability, a variety of section configuration tunnels such as rectangle, arch, trapezoidal, and energy can be formed
Realize selective cutting cutting, outer dimension weight is small, high production efficiency, is convenient for roadway support, low energy consumption.Cantilevered portion at present
The cutterhead for dividing the operating mechanism of section boring machine to use the configuration of more picks, from Cutting Performance, it is difficult to meet cutting wellf
>8 or more total rock lane, not only tool wear is extremely serious, and the big energy consumption of Dust Capacity obviously increases, the vibration aggravation of machine, every year
Tunnelling overall length is 9000 km, and wherein total rock tunnel is 20%~30%, and 90% is dug using big gun, develops and is suitable for total rock tunnel
Overhang portion section boring machine operating mechanism, very urgently.
