Abstract
The utility model relates to a retractable push-pull device of a road header. A control valve set of a push-pull mechanism is connected to a road header operating table, a cylinder seat is connected to the rear portion of the road header, a transition hinge is hinged to the cylinder seat, and one end of a push-pull cylinder is hinged to the transition hinge while the other end is connected to a stop ring of a tunnel bottom board. The retractable push-pull device is capable of realizing automatic operational ability of the road header in a steep-slope tunnel, reducing work intensity and increasing working efficiency and boring speed.
Description
Technical field
The utility model relates to a kind of development machine push-pull device at fixed, particularly is installed in the scalable push-pull device at fixed at development machine rear portion.
Background technology
In the prior art, development machine can't normally be walked when the heavy grade underworkings is worked or need and be realized climbing and descending by external force, and needs the special messenger to operate external force, influence driving speed, and efficient is low, and safety factor is little.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, and a kind of scalable push-pull device at fixed that is installed in the development machine rear portion is provided, and can realize the AUTONOMOUS TASK of development machine in the heavy grade tunnel, reduces labour intensity, increases work efficiency, and improves driving speed.
The purpose of this utility model realizes by following measure: the control valve group 2 that connects push-pull mechanism 3 on development machine 1 console, by handling the push pull maneuver that control valve group 2 realizes push-pull mechanism 3, connect oil cylinder seat 4 at development machine 1 rear portion, transition hinge 5 is hinged with oil cylinder seat 4, can realize rotation, push-and-pull cylinder 6 one ends are hinged on the transition hinge 5, and its other end connects the thrust ring 7 of roadway floor.
The other end of above-mentioned push-and-pull cylinder 6 also can be connected with the round-link chain 8 that is fixed in the tunnel.
The hydraulic power source of said apparatus links to each other with development machine 1 hydraulic power source.
Its operating principle is: when development machine 1 climbing work, by operation control valve group 2, make push-and-pull cylinder 6 realize stretching out action, push-and-pull cylinder 6 acts on the thrust ring 7 that is fixed on roadway floor, thereby give 1 one thrusts that make progress of development machine, to satisfy the climbing of development machine 1 itself.
When development machine 1 descending is worked, by operation control valve group 2, make push-and-pull cylinder 6 realize contractive action, push-and-pull cylinder 6 shrinks, and drags the round-link chain 8 that is tightly fixed on the tunnel, thereby gives 1 one pulling force that make progress of development machine, does not glide when satisfying development machine 1 descending.
Description of drawings
Accompanying drawing of the present utility model has:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1 is that development machine, 2 is that control valve group, 3 is push-pull mechanism
Fig. 3 is the utility model push-pull mechanism schematic diagram.
Among the figure: 4 is that oil cylinder seat, 5 is round-link chain for thrust ring, 8 for push-and-pull cylinder, 7 for transition hinge, 6
The specific embodiment
With reference to accompanying drawing is an embodiment of the present utility model, on development machine 1 console, be connected with the control valve group 2 of push-pull mechanism 3 by rivet welding and bolt, on development machine 1 rear portion, connect oil cylinder seat 4 by rivet welding, transition hinge 5 is hinged on the oil cylinder seat 4 by bearing pin, push-and-pull cylinder 6 one ends are hinged on the transition hinge 5 by bearing pin, and its other end connects the thrust ring 7 of roadway floor.
The hydraulic power source of said apparatus links to each other with development machine 1 hydraulic power source.
