Abstract
The utility model relates to a geophysical prospecting non valve type foam impacter, which is mainly composed of a lower connector, a guiding sleeve, a piston, an inner cylinder sleeve, an air intake seat and an upper connector. The utility model is characterized in that a drill head is connected with the lower connector through an integral key, the position of the drill head is limited through a retaining ring, the lower connector is connected with an outer cylinder sleeve though a thread, the guiding sleeve and the inner cylinder sleeve are positioned on the retaining ring and used for positioning the piston, the air intake seat is arranged on the inner cylinder sleeve, the upper connector is connected with the outer cylinder sleeve through a thread, the piston is matched with the inner cylinder sleeve, a radial air hole on the inner cylinder and a radial air hole on the guiding sleeve to realize the function of gas distribution, and therefore the piston realizes vertical reciprocating movement. The utility model efficiently solves the outstanding problems during the operation of the geophysical prospecting well drilling that the impacting power is small, rock breaking rate is low, the compacter is corroded and the piston is easy to be out of function, etc., ensures that the compacter can keep stable working performance when the foam is used as the circulating medium, and greatly enhances the working effect of the impacter.
Description
Technical field
The utility model relates to a kind of exploration drilling tool, especially a kind of physical prospecting valveless formula foam impactor.
Background technology
It is a kind of advanced person drilling technology efficiently that foam impacts rotary drilling, it is fast to have rate of penetration, characteristics such as hole quality is good, have great significance for a drilling technique difficult problem that solves under leakage, crack, caving ground and drought and water shortage condition, impactor is that foam impacts requisite equipment in the rotary drilling technology.Up to the present, that uses in the percussive-rotary drilling of physical prospecting industry foam is still the conventional valve formula air hammer that has, do not have special at the valveless formula foam impactor that designs as circulatory mediator with foam, with the valve formula arranged compare, it is littler that valveless formula impactor has an air consumption, ballistic work is bigger, the advantage that efficiency of breaking rock is higher, in addition because foam has certain corrosivity, generally, impactor is using a period of time can occur the phenomenon that piston and inner cylinder liner are corroded later, and piston lost efficacy after the impact of experience a period of time easily, and this will have a strong impact on the performance and the life-span of impactor.
Therefore improve the work effect of impactor, guarantee that impactor can keep stable service behaviour when using foam as circulatory mediator, it is little to solve the ballistic work that occurs in the physical prospecting drillng operation, efficiency of breaking rock is low, impactor is corroded and the easy outstanding problem such as inefficacy of piston, has become the task of top priority in present technique field.
The utility model content
The purpose of this utility model is to provide a kind of physical prospecting valveless formula foam impactor, this impactor can effectively improve the ballistic work of impactor, keeps good job stability, effectively prevents the corrosion of foam, strengthen the shock resistance of piston, thereby improve the functional performance and the life-span of impactor.
The technical scheme that its technical problem that solves the utility model adopts is: adopt valveless formula structure, the valve block that cancellation has valve formula impactor the inside to use, relative position distribution by piston and inner cylinder liner and fairlead air distribution hole, inner cylinder liner and piston be all through Overheating Treatment, and at inner cylinder liner inner surface brush plating one deck nanometer resistant material.
A kind of physical prospecting valveless formula foam impactor, mainly by lower contact, fairlead, piston, inner cylinder liner, air inlet seat and top connection are formed, it is characterized in that, described drill bit is connected by spline with lower contact, and the position of limiting drill bit by snap ring, lower contact and outer cylinder sheath are by being threaded, fairlead and inner cylinder liner are positioned on the snap ring, be used for positioning piston, it on the inner cylinder liner air inlet seat, top connection and outer cylinder sheath be by being threaded, thus on described piston and inner cylinder liner and the inner cylinder liner radially the radially pore on pore and the fairlead cooperate the effect that reaches distribution to make piston realize pumping.
The utility model inner cylinder liner and piston be all through Overheating Treatment, and at inner cylinder liner inner surface brush plating-layer nanometer resistant material.Inner cylinder liner adopts 35CrMo, and hard surfacing hardness reaches HRC50, and piston adopts the 20Ni4Mo material, nitrogencase hardening, and degree of depth 1.8-2mm, hardness reaches HRC58-60.Nanometer resistant material on the inner cylinder liner surface is not only made sliding agent but also make anti-corrosion material, and thickness is 10-20 μ m.
The utility model compared with prior art has following beneficial effect: (1) impactor uses valveless formula structure, compares with valve formula impactor is arranged, and air consumption is littler, and the ballistic work of generation is bigger, and efficiency of breaking rock higher (2) inner cylinder liner adopts anti-H
2The 35CrMo of S corrosion and new Technology for Heating Processing, and carried out the anti-corrosion electric brush plating on the surface and handled, resistance to impact, abrasion resistance and the corrosion resistance (3) that have improved part compare serious situation at piston initial failure and adopt 20Ni
4Mo, and worked out rational heat treatment technology, improved the impact toughness of piston, creep resisting ability greatly.
