Abstract
The utility model belongs to drilling rig technique field, discloses a kind of crawler-type tunnel drilling rig.Its technical characteristics is: comprise frame, frame is provided with operating desk, support cylinder, support oil cylinder, reduction box being connected with crawler belt, reduction box is connected with gyrator, described frame is provided with turntable, reduction box is arranged on a spinstand, the support cylinder be fixed on reduction box is one, and support cylinder center of permanent position on reduction box overlaps with the centre of gyration of turntable.Crawler-type tunnel drilling rig provided by the utility model, fixed mechanism only has a upper support cylinder, and rig can 360 ° of revolutions, one-time positioning, and wide ranges of holing, operates easier, improve the operating efficiency of drill hole of drilling machine; The volume of rig reduces accordingly, has saved cost, and improves the compliance of boring.
Description
Technical field
the utility model belongs to drilling rig technique field, particularly relates to a kind of crawler-type tunnel drilling rig.
Background technology
the fixed form of underground coal mine crawler-type tunnel drilling rig is generally and utilizes the active force of upper support cylinder and tunnel top contact to fix rig, upper support cylinder quantity is generally 2 to 4, complex operation and affect the revolution range of rig, causes using inconvenient, affects drilling construction efficiency.
Utility model content
the technical problems to be solved in the utility model is just to provide a kind of once fixing crawler-type tunnel drilling rig that can realize 360 ° of scope borings.
for solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise frame, frame is provided with operating desk, support cylinder, support oil cylinder, reduction box being connected with crawler belt, reduction box is connected with gyrator, described frame is provided with turntable, reduction box is arranged on a spinstand, and the support cylinder be fixed on reduction box is one, and support cylinder center of permanent position on reduction box overlaps with the centre of gyration of turntable.
crawler-type tunnel drilling rig provided by the utility model, support cylinder comprises oil cylinder body and supporting member, support cylinder is fixed on Gearbox, reduction box is bolted together on turntable, reduction box is connected with a pair gear with curved teeth with gyrator, gyrator be rig creep into part, the coordinate at the permanent position center of support cylinder on reduction box overlaps with the centre of gyration coordinate of rotating mechanism, the chassis of turntable is fixed in frame, and operating desk can control the various action of gyrator, support cylinder and support oil cylinder and the movement of frame.
when crawler-type tunnel drilling rig provided by the utility model uses, crawler belt drives frame to arrive working position, manipulation operation platform, support oil cylinder is ejected, support oil cylinder is controlled respectively by banked direction control valves, free adjustment can eject length, thus makes frame maintenance level, by regulating turntable and gyrator to make rig be adjusted to suitable punch position, then ejected to contacting with tunnel end face and cannot continue to eject by operating desk control support cylinder.Now due to the interaction force between support cylinder and tunnel end face, turntable is made to be in pressured state, because gyrator and reduction box are fixed on a spinstand, after turntable pressurized is fixed, make the stability of gyrator and reduction box strengthen, and then the rocking of the centre of gyration place in process of reducing to drill, make boring safer, steady, improve drilling quality.
crawler-type tunnel drilling rig provided by the utility model, fixed mechanism only has a upper support cylinder, and rig can 360 ° of revolutions, one-time positioning, and wide ranges of holing, operates easier, improve the operating efficiency of drill hole of drilling machine; The volume of rig reduces accordingly, has saved cost, and improves the compliance of boring.
Accompanying drawing explanation
fig. 1 is the structural representation of the utility model crawler-type tunnel drilling rig.
Detailed description of the invention
be described in further details below in conjunction with the concrete structure of accompanying drawing to the utility model crawler-type tunnel drilling rig.
as shown in Figure 1, crawler-type tunnel drilling rig provided by the utility model comprises frame 1, frame 1 is provided with operating desk 2, support cylinder 3, support oil cylinder 4, reduction box 5 being connected with crawler belt 6, reduction box 5 is connected with gyrator 7, frame 1 is provided with turntable 8, reduction box 5 is arranged on turntable 8, and the support cylinder 3 be fixed on reduction box 5 is one, and the center of support cylinder 3 permanent position on reduction box 5 overlaps with the centre of gyration of turntable 8.
when crawler-type tunnel drilling rig provided by the utility model uses, crawler belt 6 drives frame 1 to arrive working position, manipulation operation platform 2, support oil cylinder 4 is ejected, support oil cylinder 4 is controlled respectively by banked direction control valves, free adjustment can eject length, thus makes frame 1 maintenance level, by regulating turntable 8 and gyrator 7 to make rig be adjusted to suitable punch position, then control support cylinder 3 by operating desk 2 and eject to contacting with tunnel end face and cannot continue to eject.Now due to the interaction force between support cylinder 3 and tunnel end face, turntable 8 is made to be in pressured state, because gyrator 7 and reduction box 5 are fixed on turntable 8, after turntable 8 pressurized is fixed, make gyrator 7 strengthen with the stability of reduction box 5, and then the rocking of the centre of gyration place in process of reducing to drill, make boring safer, steady, improve drilling quality.
the utility model is not limited only to above-mentioned form, but no matter is adopt which kind of structure, as long as identical with crawler-type tunnel drilling rig structure provided by the utility model, all falls into protection domain of the present utility model.
