Embodiment Construction
[0011] The specific content of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0012] as attached figure 1 As shown, the present invention provides a drill boom of a rock drill, which includes a main arm 2 hinged with the body 1 of the rock drill, and a jib 3 hinged with the head of the main boom 2, and the head of the jib 3 is hinged with a connecting part 7 The top surface of the connecting portion 7 is rotatably connected to the propelling plate 9 , and also includes a swinging oil cylinder 11 , one end of the swinging oil cylinder 11 is pinned to the side of the connecting portion 7 , and the other end is pinned to the propelling plate 9 . The swinging oil cylinder 11 is parallel to the bottom surface of the propulsion plate 9 , so that the propelling plate 9 swings under the driving of the swinging oil cylinder 11 .
[0013] It also includes a lifting arm oil cylinder 4, and the two ends of the liftin...

The invention provides a drill arm of a rock drill. The drill arm includes a main arm, a secondary arm, a swing cylinder, an arm lifting cylinder, telescopic cylinders and a pitch oil cylinder; the main arm is connected with a machine body of the rock drill in a hinged mode, and the secondary arm is connected with the head portion of the main arm in a hinged mode; the head portion of the secondaryarm is connected with a connecting part, and the top surface of the connecting part is rotatably connected with a pushing plate; one end of the swing cylinder is connected to the side surface of theconnecting part in a pin joint mode, and the other end of the swing cylinder is connected to the pushing plate in a pin joint mode; two ends of the arm lifting cylinder are separately fixed to the machine body of the rock drill and the main arm for changing an included angle between the main arm and the machine body of the rock drill; the two telescopic cylinders are arranged in parallel on two sides of the main arm, one ends of the two telescopic cylinders are fixed to the main arm, the other ends of the two telescopic cylinders are fixed to the secondary arm, and the telescopic cylinders areused for changing the included angle between the main arm and the secondary arm; one end of the pitch oil cylinder is connected to the secondary arm in a pin joint mode, and the other ends of the pitch oil cylinder is connected to the connecting part in a pin joint mode, and the pitch oil cylinder is used for swinging the pushing plate up and down in the vertical direction. Compared with the prior art, the drill arm of the rock drill is more smooth and safe in operation, and the service life of the rock drill is longer.
Description
technical field [0001] The invention relates to the field of rock drills, in particular to a drill arm of a rock drill. Background technique [0002] At present, high-speed drilling machinery has been widely used in the military and various civilian fields in other developed countries. In the past two years, the application of high-speed drilling machinery in my country has become more and more extensive. Used for tunnel excavation, canal excavation, mining, construction of underground caverns and other projects. The use of mechanical equipment can improve the mechanization level and work efficiency of engineering blasting, while reducing energy consumption and labor intensity of workers. [0003] The main boom and the auxiliary boom of the existing rock drill are often connected by a telescopic oil cylinder, which has the problems of poor stability, easy to shake from side to side, and shortening the service life of the drill boom. SUMMARY OF THE INVENTION [0004] The i...
