Description
Technical field:
This utility model relates to the technical field of quartering hammer, more specifically to the drill steel on a kind of hydraulic breaking hammer.
Background technology:
Quartering hammer also has 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 more effectively clear up the earth in the stone of floating and rock crevice in the effect excavating building basis.Quartering hammer is typically made up of cylinder body, piston, drill steel etc., drill steel on existing quartering hammer typically uses all-in-one-piece, the head of drill steel forms tip, the tip of drill steel easily weares and teares rust during long-term work, and need during reconditioning from quartering hammer, dismantle drill steel, dismounting inconvenience, and reconditioning the most more inconvenience.
Utility model content:
The purpose of this utility model is aiming at the deficiency of 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 uses, it is not necessary to reconditioning after head abrasion.
Technology solution of the present utility model is as follows:
nullA kind of drill steel on hydraulic breaking hammer，Including drill steel body and drill head，The two ends of drill head all form the tip of " one " font，The pillow block of annular is formed on drill head between two tips，The hole, location running through drill head outer wall is formed on the tip of drill head，The bottom of drill steel body forms the notch of V-type，The jack running through the external wall of drill steel is formed on the inwall of notch，Connecting hole is formed on drill steel body on the upside of jack，The tip of drill head one end is plugged in the notch of drill steel body，Axle sleeve all it is inserted with on drill head and drill steel body at notch，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 piece bearing pin is plugged in the connecting hole of drill steel body and the pin-and-hole of axle sleeve upper end，A piece bearing pin is plugged on the jack of drill steel body、In the hole, location of drill head one end and the pin-and-hole of axle sleeve lower end.
The external wall of described drill steel and the equal diameters of drill head outer wall, the internal diameter of axle sleeve is equal to 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 connecting hole on drill steel body and the pin-and-hole positioned on hole and axle sleeve on jack, drill head is equal for the central axis of the central axis of drill steel body jack, the central axis in hole, location, drill head one end and axle sleeve lower end pin-and-hole.
The beneficial effects of the utility model are:
Drill steel is divided into head and bar portion by it, and when the head of drill steel is provided with two, after an abrasion, the convenient head that conveniently changes uses, and then can be continuing with, thus without carrying out reconditioning；And when the equal serious wear in two of drill steel head, can directly change the head of drill steel, and without changing whole drill steel, cost-effective.
