Abstract
The utility model relates to a fiberglass reinforced plastics piston cylinder liner of a pneumatic supporter of a rock drilling machine, which comprises a piston cylinder liner body, a long outer steel jacket of the pneumatic supporter and a short outer steel jacket of the pneumatic supporter. A left outer conical surface which is adapted to the inner diameter of the long outer steel jacket of the pneumatic supporter and is paralleled and matched with the long outer steel jacket of the pneumatic supporter is arranged at the left end of the piston cylinder liner body, and a right outer conical surface which is adapted to the inner diameter of the short outer steel jacket of the pneumatic supporter and is paralleled and matched with the short outer steel jacket of the pneumatic supporter is arranged at the right end of the piston cylinder liner body. Adhesive layers are arranged on the left outer conical surface and the right outer conical surface. The piston cylinder liner body is made of non-metal glass fiber reinforced plastics. The utility model adopts the technical proposal that the left outer conical surface and the right outer conical surface which are adapted to the inner diameter of the long outer steel jacket and the short outer steel jacket of the pneumatic supporter and paralleled and matched with the long outer steel jacket and the short outer steel jacket of the pneumatic supporter is arranged at both ends of the non-metal glass fiber reinforced plastics piston cylinder liner body, thus overcoming the defaults that the service life of the piston cylinder liner is short and the piston cylinder liner is flammable and explosive because the standard duralumin pipe material piston cylinder liner has the disadvantages of poor insulating property and exceeding magnesium content. The fiberglass reinforced plastics piston cylinder liner is suitable to be used as the piston cylinder liner of the pneumatic supporters of a variety of rock drilling machines.
Description
Technical field
The utility model relates to a kind of pneumatic drill support piston-cylinder, the especially a kind of and adaptive pneumatic drill support glass fibre reinforced plastics piston-cylinder of the long and short outer steel sleeve of air leg.
Background technique
Existing pusher leg drill is widely used in the mine, railway, highway, the tunnel, the cutting operation of the cubic metre of earth and stone such as water power plant, what the piston-cylinder of its pneumatic drill support adopted all is standard duralumin pipe material, this duralumin pipe piston-cylinder ubiquity insulating property difference and the content of magnesium phenomenon that exceeds standard, in use, very easily heating produces spark behind frictional impact, influenced the Security that rock drill uses, and duralumin pipe piston-cylinder poor toughness, not anti-corrosion, be easy to generate distortion after the collision, thereby cause piston-cylinder to be scrapped, influence the working life of pneumatic drill support, simultaneously, the duralumin price is more expensive, the cost height, the manufacturing process complexity.
Summary of the invention
At above-mentioned situation, it is a kind of both simple in structure, with low cost that the purpose of this utility model is to provide, long service life, and safe and reliable pneumatic drill support glass fibre reinforced plastics piston-cylinder again.
To achieve these goals, a kind of pneumatic drill support glass fibre reinforced plastics piston-cylinder, it comprises piston-cylinder body, the long outer steel sleeve of air leg, the short outer steel sleeve of air leg, piston-cylinder body left end be provided with the long outer steel sleeve internal diameter of air leg adaptive and the identical left male cone (strobilus masculinus) that is parallel to each other, piston-cylinder body right-hand member be provided with the short outer steel sleeve internal diameter of air leg adaptive and the identical right male cone (strobilus masculinus) that is parallel to each other.
For implementation structure optimization, its further step is:
Be equipped with bonding layer on the conical surface of left side male cone (strobilus masculinus) and right male cone (strobilus masculinus).
The piston-cylinder body is to select nonmetallic glass fibre reinforced plastics for use.
The utility model adopts and to be respectively equipped with the long outer steel sleeve of air leg at the two ends of the piston-cylinder body of nonmetal glass fibre reinforced plastics material and short outer steel sleeve internal diameter is adaptive and the technological scheme of left and right male cone (strobilus masculinus) that coincide mutually, the piston-cylinder that has overcome standard duralumin pipe material causes piston-cylinder because of insulating property difference and content of magnesium exceed standard working life weak point and inflammable and explosive defective.
The beneficial effect that the utility model is produced compared to existing technology:
(1) the left and right male cone (strobilus masculinus) at piston-cylinder body two ends and bonding layer can be adapted to integral body with the long and short outer steel sleeve internal diameter of air leg, are connected firmly, reliably good rigidly, intensity height;
(2) select nonmetallic glass fibre reinforced plastics alternate standard duralumin pipe piston-cylinder body for use, good insulation preformance, good toughness, in light weight resists and pounds anti-bumping, and fire-retardant explosion arrestment is safe and reliable, the working life of obviously having improved pneumatic drill support;
(3) select nonmetallic glass fibre reinforced plastics alternate standard duralumin pipe piston-cylinder body for use, it is simple in structure, and manufacturing process is easy, has saved the non-ferrous raw material of a large amount of costlinesses, effectively reduces cost of production and user cost.
It is suitable for the usefulness of various pneumatic drill support piston-cylinders.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Description of drawings
Fig. 1 is the structure sectional view of a kind of pneumatic drill support glass fibre reinforced plastics of the utility model piston-cylinder.
Among the figure 1, the piston-cylinder body, 2, the long outer steel sleeve of air leg, 3, the short outer steel sleeve of air leg, 4, left male cone (strobilus masculinus), 5, right male cone (strobilus masculinus), 6, bonding layer.
Embodiment
Referring to accompanying drawing, a kind of pneumatic drill support glass fibre reinforced plastics piston-cylinder, it comprises piston-cylinder body 1, the long outer steel sleeve 2 of air leg, the short outer steel sleeve 3 of air leg, adopt the metallic hard aluminum pipe to do piston cylinder cover body 1 existing hidden danger in order to eliminate traditional pneumatic drill support, present embodiment adopts the nonmetal glass fibre reinforced plastics of better performances to replace the metallic hard aluminum pipe, and from piston-cylinder body 1 and the long outer steel sleeve 2 of air leg, the linkage structure of the short outer steel sleeve 3 of air leg is improved: piston-cylinder body 1 left end is set to left male cone (strobilus masculinus) 4, this left side male cone (strobilus masculinus) 4 and long outer steel sleeve 2 internal diameters of air leg are adaptive and be parallel to each other identical, piston-cylinder body 1 right-hand member is set to right male cone (strobilus masculinus) 5, and short outer steel sleeve 3 internal diameters of this right side male cone (strobilus masculinus) 5 and air leg are adaptive and be parallel to each other identical.For simplified manufacturing technique, reduce production costs and reach whole and coincide, it is firm more, reliable that it is connected, and has a good rigidly, the intensity height, the characteristics of safe and reliable, long service life, on the right male cone (strobilus masculinus) 5 of the left male cone (strobilus masculinus) 4 of piston-cylinder body 1 and piston-cylinder body 1, establish one deck bonding layer 6, through of firm the docking of bonding layer 6 realization piston-cylinder bodies 1, thereby prevent that effectively pneumatic drill support from causing security incident because of the structure and the material of piston-cylinder body 1 with gentle short legs outer steel sleeve 3 internal diameters of long outer steel sleeve 2 internal diameters of air leg.
