Abstract
The utility model relates to a random protective system of the roadheader, a swing oil cylinder is arranged on the cutting arm, the other end of the oil cylinder is articulated with a swing arm 5, the swing arm is articulated with one end of the support oil cylinder, the other end of the support oil cylinder is articulated with a guard plate, one end of the lifting oil cylinder is fixed on the swing arm, and the other end is articulated with the guard plate. The system increases protective function and makes workers safer on the anchor protecting work, decreases labor intensity of workers, reduces the supporting time and then reaches the aim of improving tunneling speed.
Description
Technical field
The utility model relates to a kind of guard system at random that is installed on the development machine.
Background technology
Existing multiple support form mostly is a mechanism simple and easy, independent, by manually promoting, 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 safety, guard system at random efficiently of being installed on the development machine is provided, and can realize airborne and automatic, also can realize tunneling combination with supporting, can increase the supporting safety, reduce labour intensity, improve driving speed.
The purpose of this utility model realizes by following measure: the guard system at random of development machine is telescopic foldable mechanism, on development machine, connect supporting mechanism controls valve group, on the tunneling machine cutting arm, connect oscillating oil cylinder, the other end of oscillating oil cylinder is hinged on the swing arm, swing arm links to each other by slideway with telescopic arm, hinged support cylinder one end of telescopic arm, the other end of support cylinder is hinged on the backplate, telescopic oil cylinder one end is fixed on the swing arm, the other end is hinged on the telescopic arm, the upper end and the backplate of telescopic arm are hinged, and the hydraulic system of native system is communicated with the fuel tank of development machine itself, and guard system provides power resources by the fuel tank of development machine itself at random.
Above-mentioned telescopic arm is the slideway type telescopic mechanism with connecting of swing arm.
Above-mentioned swing arm and oscillating oil cylinder and tunneling machine cutting arm to be connected to bearing pin hinged, on tunneling machine cutting arm both sides or top.
The guard system at random of development machine is mounted on the development machine safety, guard system at random efficiently, realize the airborne and automatic of guard system at random, also realized the combination of driving and supporting, increased the supporting safety, reduce labour intensity, improved driving speed.
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 structural representation of supporting mechanism among Fig. 1.
In the accompanying drawing: 1 is supporting mechanism, and 2 is development machine, 3 supporting mechanism controls valve groups, and 4 is oscillating oil cylinder, and 5 is swing arm, and 6 is support cylinder, and 7 is telescopic oil cylinder, and 8 is telescopic arm, and 9 is backplate.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1 is an embodiment of the present utility model, and the guard system at random of development machine is telescopic foldable mechanism, can realize double-layer folding.On development machine 2, connect supporting mechanism controls valve group 3, on development machine 2 cutting arms, be connected with oscillating oil cylinder 4, the other end of oscillating oil cylinder 4 is hinged on the swing arm 5, swing arm 5 is connected with telescopic arm 8 usefulness slideways, one end of telescopic arm 8 hinged support cylinders 6, the other end of support cylinder 6 is hinged on the backplate 9, telescopic oil cylinder 7 one ends are fixed on the swing arm 5, the other end is hinged on the telescopic arm 8, the upper end of telescopic arm 8 and backplate 9 are hinged, the fuel tank of the hydraulic system of native system and development machine 2 itself is communicated with, and at random guard system provides power resources by the fuel tank of development machine itself.
Above-mentioned telescopic arm 8 is the slideway type telescopic mechanism with connecting of swing arm 5.
It is hinged that above-mentioned swing arm 5 and oscillating oil cylinder 4 and development machine 2 cutting arms are connected to bearing pin, in development machine 2 cutting arm both sides.
Function narration: under its working condition, at first promote supporting mechanisms 1 by oscillating oil cylinder 4, the vertical position of the flexible adjustment supporting mechanism 1 by oscillating oil cylinder 4 stands on development machine 2 cutting arms it.Secondly promote backplate 9 by support cylinder 6, backplate 9 is launched, telescopic oil cylinder 7 promotes telescopic arm 8 then, telescopic arm 8 is stretched out be raised to working depth, thereby reach the supporting purpose.
Under off working state, can after being folded, supporting mechanism 1 drop on development machine 2 cutting arms by oscillating oil cylinder 4, support cylinder 6, telescopic oil cylinder 7 adjustment, do not influence the operate as normal of development machine.
Claims (2)
1, a kind of guard system at random of development machine, go up connection supporting mechanism controls valve group (3) at development machine (2), the guard system at random that it is characterized in that development machine is telescopic foldable mechanism, describedly on development machine (2) cutting arm, connect oscillating oil cylinder (4), the other end of oscillating oil cylinder (4) is hinged on the swing arm (5), swing arm (5) is connected by slideway with telescopic arm (8), one end of telescopic arm (8) lower end and support cylinder (6) is hinged, the other end of support cylinder (6) is hinged on the backplate (9), telescopic oil cylinder (7) one ends are fixed on the swing arm (5), the other end is hinged on the telescopic arm (8), the upper end of telescopic arm (8) and backplate (9) are hinged, and the hydraulic system of native system is communicated with the fuel tank of development machine (2) itself.
