Abstract
The utility model is related to a kind of boom-type roadheader with pre- cutting means, including boom-type roadheader, it is provided with the cutting arm cover plate of the original cutting units of boom-type roadheader by supporting table, telescopic oil cylinder, the pre- cutting means of cantilever and cutterhead composition, wherein, supporting table is installed on cutting arm of tunneling machine cover plate, the long straight dovetail groove in one of longitudinal direction is provided with supporting table, cantilever is located in supporting table and can slided along its dovetail groove, the cylinder body end of telescopic oil cylinder is articulated with cutting arm of tunneling machine cover plate, one end of cantilever is connected with the tailpiece of the piston rod of telescopic oil cylinder, the other end of cantilever is connected with cutterhead.During tunnelling, using the pre- cutting means, cut goes out the profile of drift section exactly first, then recycle region quick cut of the original cutting units of development machine within drift section profile, the cut of section can be thus completed with faster speed, and then improves the drivage efficiency of development machine and the precision of section shaping.
Description
Technical field
The utility model content belongs to colliery digging equipment technical field, is related to a kind of cantilevered with pre- cutting means
Development machine.
Background technology
Boom-type roadheader so far tunnelling production in be used widely, but conventional boom-mounted development machine due to
The structure of its itself former configuration cutting units is limited, and during tunnelling, also there are drift section forming accuracy not high
Problem, and drivage efficiency is in urgent need to be improved.
Utility model content
The purpose of this utility model is to solve that there is provided a kind of conjunction of structure to the above mentioned problem that prior art is present
Reason, cut easy to operate, that drift section can be completed with fast speed, so as to improve the tool of drivage efficiency and section shaping precision
There is the boom-type roadheader of pre- cutting means.
In order to which the technical solution for reaching above goal of the invention and taking is as described below：
A kind of boom-type roadheader with pre- cutting means, including boom-type roadheader, it is characterized in that in cantilevered pick
The cutting arm cover plate for entering the original cutting units of machine is provided with pre- a section be made up of supporting table, telescopic oil cylinder, cantilever and cutterhead
Device is cut, wherein, supporting table is installed on cutting arm of tunneling machine cover plate, and the long straight dovetail groove in one of longitudinal direction is provided with supporting table,
Cantilever is located in supporting table and can slided along its dovetail groove, and the cylinder body end of telescopic oil cylinder is articulated with cutting arm of tunneling machine cover plate,
One end of cantilever is connected with the tailpiece of the piston rod of telescopic oil cylinder, and the other end of cantilever is connected with cutterhead.
In the above-mentioned boom-type roadheader with pre- cutting means, telescopic oil cylinder is two-stage telescopic oil cylinder.
Compared with prior art, the beneficial effects of the utility model are：Devise the cut in conventional boom-mounted development machine
Install the scheme of a pre- cutting means on arm cover plate additional, during tunnelling, cut goes out exactly using the pre- cutting means first
The profile of drift section, then recycles region quick cut of the original cutting units of development machine within drift section profile,
The cut of section can be thus completed with faster speed, and then improves the drivage efficiency of development machine and the essence of section shaping
Degree.

Embodiment
Referring to accompanying drawing, the boom-type roadheader described in the utility model with pre- cutting means is by boom-type roadheader 6
Body and on boom-type roadheader 6 pre- cutting means composition, pre- cutting means therein again by supporting table 4, stretch
Contracting oil cylinder 3, cantilever 2 and cutterhead 1 are constituted.Supporting table 4 is fixed on the cutting arm cover plate 5 of the original cutting units of development machine, support
Platform 4 drives dovetail groove (Fig. 4) above.Telescopic oil cylinder 3 is two-stage telescopic oil cylinder, and the cylinder body end of telescopic oil cylinder 3 is articulated with cantilevered pick
On the cutting arm cover plate 5 for entering the original cutting units of machine, the tailpiece of the piston rod of telescopic oil cylinder 3 is connected with the cantilever 2 of pre- cutting means, cantilever
2 other end is connected with cutterhead 1.When the piston rod of telescopic oil cylinder 3 is elongated or shortened, the cantilever of pre- cutting means can be pulled
2 slide in supporting table 4.
During utility model works, original cutterhead of boom-type roadheader 6 is shunk and tunnel can not be contacted first and break
Face, from the normal work of the cutterhead 1 without influenceing pre- cutting means；Then control boom-type roadheader 6 hoist cylinder and
Angling cylinder, makes cutterhead 1 move to behind appropriate position, starts the electrical control equipment of pre- cutting means, by the work of telescopic oil cylinder 3
Stopper rod stretches out, and the cutterhead 1 of pre- cutting means is contacted drift section, and manipulate the accurate cut drift section profile 7 of cutterhead 1
(Fig. 5)；After the completion of the cut of drift section profile 7, the piston rod of telescopic oil cylinder 3 is shunk, makes the cutterhead 1 time of pre- cutting means
To initial position；Original cutterhead of boom-type roadheader 6 is extended again, the region being allowed within drift section profile 7 is fast
The cut of whole section is completed fastly.
