Abstract
The utility model discloses a kind of development machine extension type elevating conveyor, comprise the aircraft tail shelf group, middle frame group and the headstock group that set gradually from front to back, described middle frame group comprises middle frame, described middle frame group also comprises the intermediate warp frame that can slide along middle frame, the rear end of this intermediate warp frame is hinged with telescopic oil cylinder, and the telescopic end of telescopic oil cylinder is connected with the front end of described middle frame.The arranged on left and right sides of described middle frame is provided with guide-track groove, the left and right relative inner of described intermediate warp frame is provided with the left and right guide rail extending into and can slide along guide-track groove in guide-track groove, when the telescopic end of described telescopic oil cylinder stretches out or retracts, intermediate warp frame is matched by left and right guide rail can slide along middle frame with left and right guide-track groove.Intermediate warp frame of the present utility model can stretch out along middle frame or retract, and facilitates development machine to turn, and need not add middle frame simultaneously, reduce the labour intensity of workman.
Description
Technical field
The utility model relates to a kind of development machine elevating conveyor, especially relates to a kind of development machine extension type elevating conveyor.
Background technology
Traditional development machine elevating conveyor is formed primarily of aircraft tail shelf group, middle frame group and headstock group, middle frame group generally all needs connection two to save above middle frame, tunnel just from development machine and need constantly to add middle frame to drilling depth certain distance, plenty of time and manpower is so just needed to go to regulate, and after elevating conveyor completes all assemblings, whole length is all long, very difficult in development machine turning process.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of development machine does not need to add the development machine extension type elevating conveyor that middle frame and development machine be easy to turn in tunnel in excavation operation process.
For solving the problems of the technologies described above, development machine extension type elevating conveyor of the present utility model, comprise the aircraft tail shelf group, middle frame group and the headstock group that set gradually from front to back, described middle frame group comprises middle frame, described middle frame group also comprises the intermediate warp frame that can slide along middle frame, the rear end of this intermediate warp frame is hinged with telescopic oil cylinder, and the telescopic end of telescopic oil cylinder is connected with the front end of described middle frame.
As further improvement of the utility model, the arranged on left and right sides of described middle frame is provided with guide-track groove, the left and right relative inner of described intermediate warp frame is provided with the left and right guide rail extending into and can slide along guide-track groove in guide-track groove, when the telescopic end of described telescopic oil cylinder stretches out or retracts, intermediate warp frame is matched by left and right guide rail can slide along middle frame with left and right guide-track groove.
Adopt the development machine extension type elevating conveyor of said structure, due to a left side for middle frame, right both sides are provided with guide-track groove, a left side for described intermediate warp frame, right relative inner is provided with the left side extending into and can slide along guide-track groove in guide-track groove, right guide rail, when the telescopic end of described telescopic oil cylinder stretches out or retracts, intermediate warp frame is by left, right guide rail is with left, right guide-track groove matches and can slide along middle frame, therefore when needs middle frame group lengthens, by controlling telescopic oil cylinder, its telescopic end is stretched out, and then intermediate warp frame is skidded off, again middle frame need not be added, save manpower, its telescopic end can be retracted by controlling telescopic oil cylinder when development machine needs to turn, and then make intermediate warp frame be retracted to middle frame position, the length of middle frame group be shortened, facilitates development machine to turn.
