Description
Technical field
The utility model relates to a kind of novel Wind pressure impactor improving impactor drilling efficiency, belongs to rock drilling machinery technical field.
Background technology
Impactor is a kind of high-efficiency drilling equipment of latter stage in last century from external introduction, be widely used in the engineerings such as harbour construction, reclamation, opencut, the outdoor cubic metre of earth and stone, and low blast 90 impactor is the one that low wind pressure impactor is most widely used.Because low wind pressure impactor has, use blast is lower, low to the instructions for use of each part of impactor, use cost is low, a compressor can simultaneously to advantages such as several impactor air feed, there is the figure of this impactor at each associated construction scene, the whole nation, has the status that middle and high wind pressure impactor cannot replace.By contrast, high-wind pressure impactor have use blast higher, to each component requirement high (especially piston) and the advantage such as penetration rate is fast, also progressively obtain market accreditation.
Because high wind pressure drill bit cost is higher, its front connector card pricker structure adopts retaining ring to connect simultaneously, and more bit change must dismantle front street corner at every turn, causes inconvenience to a certain degree.In addition, the requirement of high-wind pressure impactor to equipment is higher, and common low blast air compressor machine cannot meet the requirement of high-wind pressure impactor.
The epoch of cost are considered, the factor that penetration rate, oil consumption cost and wage for workmen etc. also more and more focus on for construction party at this.The ubiquitous problem of current low wind pressure impactor is low to the effective rate of utilization of Compressed Gas, how to ensure that improving drilling efficiency under the prerequisite that low wind pressure impactor has had superiority becomes low wind pressure impactor manufacturer question of common concern.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of drilling efficiency can carrying high, normal, basic wind pressure impactor, saves the novel Wind pressure impactor of the cost of impactor boring.
In order to solve the problem, the utility model by the following technical solutions:
A kind of novel Wind pressure impactor, comprise outer tube, inner casing and fairlead is provided with in described outer tube, piston is slidably fitted with in described outer tube, wherein one end of described piston and inner casing in mating connection, the other end is connected with fairlead, and the one end near fairlead on outer tube is connected with front connector; Be connected with rear joint near one end of inner casing, front connector has card pricker structure, and this card pricker structure adopts lateral pin to connect.
Impactor can be connected with low blast drilling rod easily, more during bit change without the need to dismantling front connector, simultaneously front connector can use again low blast 90 drill bit, so design can retain in the advantage of low wind pressure impactor.
Below the further optimization of the utility model to such scheme:
The outside of rear joint is provided with the connecting thread be connected with drilling rod, and this connecting thread is square type screw thread.
Further optimization: the outer circumference surface of piston is provided with 3 place's arc grooves, often locates circumferentially direction and arranges 5-6 groove.The piston of this kind of structure has coordinated from distribution with inner casing, distribution seat, outer tube and fairlead, and distribution reliability has valve type impactor higher than traditional; Use the piston of this kind of structure, can significantly improve frequency of impact, piston draw ratio is comparatively large simultaneously, and energy transfer efficiency is higher.
Further optimization: be provided with distribution seat in described inner casing, the mutual matched in clearance in one end of described fairlead and piston forms front air chamber, and described inner casing, distribution seat and the mutual matched in clearance of the piston other end form rear gas chamber.So make use of the structural advantages of high-wind pressure impactor well.
The utility model adopts technique scheme, the structure of high-wind pressure impactor is applied to the utilization rate that low wind pressure impactor effectively can improve Compressed Gas, the material and the heat treatment requirements that are applied in the component on low wind pressure impactor low simultaneously, the high-wind pressure impactor that material cost and processing cost compare equal model is much lower, penetration rate is faster than the low wind pressure impactor of equal model, and comprehensive sexual valence is higher.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
