Abstract
The utility model discloses a novel drill rod of a hydraulic breaking hammer. The novel drill rod structurally comprises a drill rod tail, a retaining screw and a drill rod head; a connecting groove is arranged at one end of the drill rod tail, the drill rod head is provided with a rib, and the rib is fixed to the connecting groove and is reinforced by the retaining screw; and a length ratio of the drill rod tail to the drill rod head ranges from 4:1 to 3:1. Compared with a drill rod head of the traditional product, the drill rod head is machined by a novel method, and the hardness and the abrasion resistance of the drill rod head are improved. The novel drill rod has the advantages that the structure of a drill rod of an existing product is modified, an original integral structure is replaced by a segmented structure, the drill rod is divided into the drill rod tail and the drill rod head, the drill rod head is prevented from falling off by the retaining screw, only the drill rod head needs to be replaced while the drill rod tail can be reused after the novel drill rod is used for a long time, accordingly, the drill rod is high in repeating utilization rate, and energy consumption is greatly reduced.
Description
Technical field
The utility model relates to the crushing hammar drill rod in a kind of engineering machinery, is specifically related to a kind of Novel hydraulic crushing hammer drill steel.
Background technology
The New Hydraulic Impact Machine that hydraulic breaking hammer grew up the sixties in last century, take hydraulic pump as power source, oil liquid pressure is power, reciprocating motion of the pistons output impulse machine, utilize high-speed motion to impact bit shank, carry out crushing operation, obtained using comparatively widely with the boundary that digs up mine at engineering field.
Hydraulic burster is a kind of new and effective hydraulic shock vibration facility, auxiliary work parts of excavator or loader, realize the high-frequency reciprocating motion of destroyer piston in cylinder body with the hydraulic oil of machine-tool output during work, thereby hit drill steel, externally acting.
Hydraulic burster is widely used in the fields such as metallurgy, mine, railway, highway, building, urban construction, house exploitation, to the hard thing such as rock, concrete, ladle, slag, frozen soil, ice cube, cement pavement, bridge pier, building exploit, the operation such as fragmentation, dismounting.
As shown in Figure 1, the existing product that uses in the market, hydraulic crushing hammar drill rod is as the important utensil that transmits hydraulic crushing hammer hitting power crushing medium, most important in the use procedure of hydraulic breaking hammer, existing hydraulic crushing hammar drill rod mostly is overall structure, pick rod by integral quenching after the much higher hard drill steel easily fracture, during lower hardness, pick rod easily weares and teares, integrally-built drill steel in use utilization rate is only 3/5 of drill steel total length, the drill steel of changing does not have use value, causes great waste.
Summary of the invention
In order to solve deficiency of the prior art, the utility model provides a kind of Novel hydraulic crushing hammer drill steel, has that topology layout is reasonable, simple in structure, easy to maintenance, hitting dynamics increases, reduced energy consumption, the advantage such as easy to use.
The utility model is to realize by following technical scheme:
A kind of Novel hydraulic crushing hammer drill steel, its structure is made of: drill steel afterbody, retaining screw, drill head, and wherein drill steel afterbody one end is provided with link slot, and drill head is provided with fin, and fin and link slot are fixed, and by the reinforcing of retaining screw.
Described drill steel afterbody, the length ratio of itself and drill head is between 4:1～3:1.
Described drill head, it adopts new processing method than the drill head in traditional product, improves hardness and the abrasion resistance of drill head.
Described retaining screw, it has the drill head of preventing and comes off, and increases the effect of the steadiness that drill steel afterbody, drill head connect.
The utility model is by improving the existing product Rod structure, adopt the mode of segmental structure, replace original overall structure, drill steel is divided into drill steel afterbody and drill head, and prevents that by the retaining screw drill head from coming off, service time is when longer, as long as change drill head, the drill steel afterbody can be reused repeatedly, makes the drill steel recycling rate of waterused high, decrease energy consumption.
Description of drawings
Fig. 1, be the structural representation of existing product.
Fig. 2, be structural representation of the present utility model.
In Fig. 1: the 1-drill steel; The 2-drill head.
In Fig. 2: 1-drill steel afterbody; 2-retaining screw; The 3-drill head.
The specific embodiment:
Below in conjunction with drawings and Examples, the utility model is described further:
As shown in Figure 2, a kind of Novel hydraulic crushing hammer drill steel, its structure is made of: drill steel afterbody 1, retaining screw 2, drill head 3, wherein drill steel afterbody 1 one ends are provided with link slot, drill head 3 is provided with fin, and fin and link slot are fixed, and reinforces by retaining screw 2.
Described drill steel afterbody 1, the length ratio of itself and drill head is between 4:1～3:1.
Described drill head 3, it adopts new processing method than the drill head in traditional product, improves hardness and the abrasion resistance of drill head.
Described retaining screw 2, it has the drill head of preventing and comes off, and increases the effect of the steadiness that drill steel afterbody 1, drill head 3 connect.
The utility model is by improving the existing product Rod structure, adopt the mode of segmental structure, replace original overall structure, drill steel is divided into drill steel afterbody and drill head, and prevents that by the retaining screw drill head from coming off, service time is when longer, as long as change drill head, the drill steel afterbody can be reused repeatedly, makes the drill steel recycling rate of waterused high, decrease energy consumption.
It should be noted that at last: above manual is only in order to illustrate the technical solution of the utility model and use characteristic, although this manual has been described in detail the utility model with reference to the above embodiments, but, those of ordinary skill in the art should be appreciated that still and can modify or be equal to replacement the utility model; And all do not break away from technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in claim scope of the present utility model.
