Abstract
This invention discloses a driving device of tunnel development machine, solves the problems of small mine area and low working efficiency. The main technique plan is that the first and second driving heads are driven by the first and second hydraulic motor and rotated at opposite direction. the first and second hydraulic motors are set on head part of the first and second driving arm, and the trailer of the first and second driving arm is separately splice jointed to connecting seat, the connecting seat can be vertical oscillating connected to development machine frame. Guide device that can restrict its open and close motion is set on the first and second driving arm heads. Double driving head is used in this invention, and horizontal shearing of driving head can be realized, its using is safe and production efficiency is high, production zone is large, especially propitious to roadway coal cutting of small scale mine.
Description
Technical field
The present invention relates to the tunnelling machine technical field, relate in particular to a kind of mole that comprises the tunnelling machine of heading end, hydraulic motor and driving arm.
Background technology
The known small-sized tunnelling machine that is used for colliery pick coal adopts the single arm type structure mostly, and promptly a heading end is installed on the driving arm.Its shortcoming is: production zone is little, inefficiency.
Summary of the invention
Technical problem to be solved by this invention is: a kind of mole of tunnelling machine is provided, and little to solve its production zone, ineffective problem.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of mole of tunnelling machine, comprise heading end by fluid motor-driven, hydraulic motor is installed on the head of driving arm, described heading end comprises first and second heading ends that can rotate in opposite directions, described hydraulic motor comprises first and second hydraulic motors, and described driving arm comprises the first and second driving arms; The afterbody of the first and second driving arms is hinged with Connection Block respectively, but Connection Block is connected with the longitudinal oscillation of development machine frame; The middle part of the first and second driving arms is provided with and can makes it make the power set of open and close movement; The head of the first and second driving arms is provided with and can limits the guiding device that it does open and close movement.
Owing to adopted technique scheme, first and second hydraulic motors drive first and second heading ends respectively, realize the double end driving, have improved its drivage efficiency greatly; Because first and second heading ends rotate in opposite directions, and the transverse component that produces during driving can be cancelled out each other, make mole more steady when work simultaneously.The afterbody of the first and second driving arms is hinged with Connection Block respectively, its middle part is provided with and can makes it make the power set of open and close movement, its head is provided with and can limits the guiding device that it does open and close movement, when the first and second driving arms were outwards opened, Connection Block drove first and second heading ends and does the lateral shear motion; But Connection Block is connected with the longitudinal oscillation of development machine frame, thereby heading end can do the longitudinal shear campaign, but both lateral shear of heading end, but lateral shear again, thereby enlarged its production zone.
As a kind of improvement, described Connection Block comprise one can with first and second the driving arms the hinged slide block of afterbody, the lifting support that can be connected with the swing of development machine frame is provided with the telescopic oil cylinder that slide block is moved as axial stretching along guide rail between described lifting support and the slide block.Its effect is: when telescopic oil cylinder stretches, drive heading end by slide block and axially move, development machine need not to move, and heading end just can be realized axial driving, and its production zone is further enlarged.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
A kind of mole of tunnelling machine, shown in Fig. 1 and Fig. 2 were common, the first and second heading end 9a and 9b were driven by the first and second hydraulic motor 1a and 1b respectively.The first and second hydraulic motor 1a and 1b are installed on first and second driving arm 2a and the 2b respectively; The afterbody of the first and second driving arm 2a and 2b is articulated in slide block 3 by bearing pin 10 respectively, slide block 3 is installed on the lifting support 6 that can be connected with the swing of development machine frame, lifting support 6 both sides are equipped with frid 7, slide block 3 can slide along the dovetail groove of frid 7, certainly, also can be the track of other form, as long as slide block 3 can both can lifting support 6 endwisely slipping of upper edge heading end; Be provided with telescopic oil cylinder 5 between lifting support 6 and the slide block 3.The middle part of the first and second driving arm 2a and 2b outwards is bent into pincer respectively, pincerlike inside is provided with and can makes it be first, second folding oil cylinder 4a, the 4b of open and close movement, the tailpiece of the piston rod of the first folding oil cylinder 4a and cylinder body end are hinged with the first driving arm 2a and slide block 3 respectively, and the tailpiece of the piston rod of the second folding oil cylinder 4b and cylinder body end are hinged with the second driving arm 2b and slide block 3 respectively.The upper and lower both sides of the first and second driving arm head portions are respectively equipped with upper and lower clamping plate 8a, 8b, the middle part of upper and lower clamping plate 8a, 8b and end are connected by bolt respectively makes its head that is held on the first and second driving arm 2a and 2b, just form between upper and lower clamping plate 8a, the 8b can limit the first and second driving arm 2a and 2b folding laterally lead groove.
Various motion of the present invention is by hydraulic motor or hydraulic oil cylinder driving, and no spark phenomenon can not cause gas explosion, and is safe in utilization, especially is fit to the tunnel pick coal of small-size coal mine.
