Abstract
The invention discloses a drill rod on a hydraulic breaking hammer. The drill rod comprises a drill rod body and a drill rod head. Linear tips are formed at the two ends of the drill rod head. An annular shaft table is formed at the position, between the tips at the two ends of the drill rod head, on the drill rod head. Positioning holes penetrating the outer wall of the drill rod head are formed in the tips of the drill rod head. A V-shaped notch is formed in the bottom end of the drill rod body. Inserting holes penetrating the outer wall of the drill rod body are formed in the inner wall of the notch. Connecting holes are formed in the positions, on the upper sides of the inserting holes, on the drill rod body. The tip at one end of the drill rod head is inserted and connected in the notch of the drill rod body. The part, at the notch, of the drill rod head and the drill rod body is sleeved with a shaft sleeve in an inserted manner. The shaft sleeve abuts against the shaft table of the drill rod head. Two pin holes penetrating the outer wall of the shaft sleeve are formed in the upper end and the lower end of the shaft sleeve. One pin shaft is inserted and connected in the connecting holes of the drill rod body and the pin holes in the upper end of the shaft sleeve. According to the drill rod on the hydraulic breaking hammer, the drill rod is divided into the head part and the rod part, the two tips are arranged at the drill rod head, after one tip is abraded, the tip can be conveniently replaced with the other tip for use, then the drill rod can be used continuously, and therefore the drill rod does not need to be polished.

Background technology:
Quartering hammer is also referred to as Hydraulic pick, Hydraulic clay gun, big gun machine, broken first-class, its power resources are the pressure oil that the pumping plant of excavator or loader provides, and it can at the earth more effectively cleared up in floating stone and rock crevice excavating building foundation.Quartering hammer is generally made up of cylinder body, piston, drill steel etc., drill steel on existing quartering hammer generally adopts all-in-one-piece, the head of drill steel forms tip, the tip of drill steel easily weares and teares rust in long-term work process, and during reconditioning, need drill steel to dismantle from quartering hammer, dismounting is inconvenient, and reconditioning also comparatively inconvenience.
Summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and provides the drill steel on a kind of hydraulic breaking hammer, and its drill steel is divided into head and bar portion, conveniently changes head and use, without the need to reconditioning after head wearing and tearing.
Technology solution of the present invention is as follows:
Drill steel on a kind of hydraulic breaking hammer, comprise drill steel body and drill head, the shaping tip all forming ' one ' font in the two ends of drill head, drill head between the tip at drill head two ends forms the pillow block of annular, the tip of drill head forms the locating hole running through drill head outer wall, the bottom of drill steel body forms the notch of V-type, the inwall of notch forms the jack running through the external wall of drill steel, drill steel body on the upside of jack forms connecting hole, the tip of drill head one end is plugged in the notch of drill steel body, notch place drill head and drill steel body are all inserted with axle sleeve, axle sleeve is resisted against on the pillow block of drill head, the upper and lower two ends of axle sleeve form two pin-and-holes running through axle sleeve outer wall, a bearing pin is plugged in the connecting hole of drill steel body and the pin-and-hole of axle sleeve upper end, a bearing pin is plugged on the jack of drill steel body, in the locating hole of drill head one end and the pin-and-hole of axle sleeve lower end.
The equal diameters of the external wall of described drill steel and drill head outer wall, the internal diameter of axle sleeve equals the diameter of the external wall of drill steel.
The central axis of described drill steel body connecting hole and the central axis of axle sleeve upper end pin-and-hole are on the same line, on the same line, the aperture of the locating hole on the connecting hole on drill steel body and jack, drill head and the pin-and-hole on axle sleeve is equal for the central axis of the central axis of drill steel body jack, the central axis of drill head one end locating hole and axle sleeve lower end pin-and-hole.
Beneficial effect of the present invention is:
Drill steel is divided into head and bar portion by it, and when the head of drill steel is provided with two, after wearing and tearing, the convenient head that conveniently changes uses, and then can carry out continuation and use, thus without the need to carrying out reconditioning; And when the equal serious wear in two of drill steel head, the head of drill steel directly can be changed, and without the need to changing whole drill steel, save cost.
Accompanying drawing illustrates:
