Abstract

A drill shank for hydraulic crushing hammer belongs to hydraulic crushing hammer attachment technical field, comprising a main drill shank body with a point head; a flat pin groove is arranged at the rear part of the main drill shank body. The utility model is characterized in that the outer wall of the head of the main drill shank body is corresponding provided with concaving grooves. The hydraulic crushing hammer is of artful design, simple structure; by arranging concaving groove at the head of the drill shank, a great deal of heat and dust particles caused during crushing can be discharged in time; the fatigue of drill shank is effectively reduced; the service lift is enhanced. And after the wearing of the drill shank head, a relative pointed shape can still be kept; the wearing ability and the service life are enhanced by 60-80 percent compared with a common drill shank for hydraulic crushing hammer, the crushing ability is more strong.

Description

Hydraulic crushing hammar drill rod
Technical field
The utility model belongs to hydraulic breaking hammer accessory technical field, is specially hydraulic crushing hammar drill rod.
Background technology
Hydraulic breaking hammer is widely used in the fields such as metallurgy, mine, railway, highway, building, municipal works, house exploitation, to hard thing such as rock, concrete, tunnel piercing, ladle, slag, frozen soil, ice cube, pitch, cement pavement, bridge pier, building exploit, operation such as fragmentation, removing, excavation, punching, dismounting, can also be by behind the conversion drill steel, be used for riveting, eliminate rust, vibrate, operation such as compacting, piling, hydraulic crushing hammar drill rod belongs to easily-consumed products.
At present, it is main body that the hydraulic crushing hammar drill rod of selling on the market mostly adopts the alloy round steel, and its head is processed into in-line, pyramid, taper shape or blunt shape, and afterbody is provided with the cotter pilotage groove, finish through Overheating Treatment again, have wear-resisting, heat-resisting, not frangibility, characteristic such as be difficult for splitting.But when crushing operation, a large amount of heats, the grit of generation can't in time be discharged, and greatly reduce the service life of drill steel, have increased engineering cost.
The utility model content
At the above-mentioned problems in the prior art, the purpose of this utility model is to design the technical scheme that provides a kind of head that the hydraulic crushing hammar drill rod of groove is set, to strengthen the service life of drill steel.
Described hydraulic crushing hammar drill rod comprises the drill steel main body of being with the drill steel tip, and drill steel main body afterbody is provided with the cotter pilotage groove, it is characterized in that drill steel body head outer wall is equipped with groove.
Described hydraulic crushing hammar drill rod is characterized in that drill steel body head outer wall is equipped with four grooves.
Described hydraulic crushing hammar drill rod is characterized in that the drill steel main body is a column structure, and the drill steel tip is a pyramidal shaped structures.
Described hydraulic crushing hammar drill rod is characterized in that the drill steel main body is a column structure, and the drill steel tip is a conical structure.
Described hydraulic crushing hammar drill rod is characterized in that the drill steel main body is a column structure, and the drill steel tip is the in-line structure.
Above-mentioned hydraulic crushing hammar drill rod is skillfully constructed, and is simple in structure, by being equipped with groove at the drill steel head, can in time discharge a large amount of heats and the grit that produce when fragmentation is worked, effectively alleviated the fatigue strength of drill steel, improved its service life.And after the wearing and tearing of drill steel head, still can keep the shape of point relatively, its wearability and service life have been improved 60-80% than general hydraulic crushing hammar drill rod, and breaking capacity is stronger.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2-3 is other example structure schematic diagram.
The specific embodiment
As shown in the figure, hydraulic crushing hammar drill rod comprises the drill steel main body 3 that the alloy round steel is made, and drill steel main body 3 heads are drill steel tip 1, can make pyramid, taper shape or in-line structure according to the difference of use occasion, and this position directly contacts with the thing that is broken.The aft mounted cotter pilotage groove 4 of drill steel, the cotter pilotage of hydraulic breaking hammer are pegged graft with cotter pilotage groove 4 and are cooperated, and drill steel is fixed on the quartering hammer.On the drill steel main body 3 head wall bodies four grooves 2 are set evenly, two or more grooves 2 also can be set, its front end is difform drill steel tip 1.During crushing operation, heat, grit can be discharged in groove 2 timely, have effectively alleviated the fatigue strength of drill steel, have improved its service life.And after the drill steel head wearing and tearing, still can keep the shape of point relatively, also correspondingly prolong service life.In addition, the heat treated hardened layer that is arranged so that drill steel of groove 2 is thicker, and about the big 3-5 of HRC of the general drill steel of inner hardness ratio, breaking capacity is stronger.
