Description
Technical field
The utility model relates to down-hole hammer, particularly uses the down-hole hammer on long-spiral drilling machine, rotary drilling rig.
Background technology
Foundation pile construction uses rig to drive drill bit at earth-boring usually, and then the mixed earth of perfusion reinforcing bar becomes foundation pile in the hole; But when general drill bit runs into hard rock stratum, then can't construct, and in practice of construction, the upper surface that foundation pile only arrives the rock stratum can not satisfy real demand, for this reason, special down-hole hammer then occurred.But present most down-hole hammer is independently, diameter and the degree of depth of its boring are little, therefore, the down-hole hammer that combination occurred again, as being 201020550979.7 at application number, the applying date is to be to disclose a kind of combined down-hole hammer on April 6th, 2011 notice of authorization day on September 30th, 2010, comprise hookup, stake body and be installed in the impactor of the plural minor diameter on the stake body, hookup is the cylindricality fittings body, and the cylindricality joint of cylindricality fittings body and drilling rod is pegged graft and fixed by at least one bearing pin and sealing mat.Although above-mentioned down-hole hammer can carry out the construction of large diameter, deep borehole,, the installation and removal down-hole hammer is inconvenient, causes maintenance inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of easy to maintenance, cluster down-hole hammer that maintenance cost is low.
For achieving the above object, a kind of cluster down-hole hammer comprises the down-hole hammer more than two, also comprises connector, upper connector and lower connector; The upper end of upper connector is connected on the connector; The lower end of upper connector has jack, and the upper end of lower connector has plug, and plug is inserted in the jack, is provided with fastener between upper connector and the plug; The upper end of upper connector is equipped with the nut that equates with down-hole hammer quantity, and upper connector is provided with the first perforation, and lower connector is provided with the second perforation, and upper end second perforation of down-hole hammer, the first perforation are connected with nut.
Said structure, owing to being provided with connector, upper connector and lower connector, and lower connector is connected with upper connector by the mode of pegging graft, and simultaneously, down-hole hammer is threaded connection on the nut, when the installation and removal down-hole hammer, as long as lower connector is separated from upper connector, and rotating nut can realize, therefore, the installation and removal down-hole hammer is convenient, and the cost of maintenance is also low.Owing to a plurality of down-hole hammers being installed, therefore, can having carried out the construction of large diameter, deep borehole.
As improvement, upper connector comprises upper bush and upper reinforcing plate, and upper reinforcing plate is located in the upper bush.The upper connection physical efficiency of this structure reduces consumptive material, and can improve the upward intensity of connector after upper reinforcing plate is set.
As improvement, be positioned at upper reinforcing plate topmost and be provided with the nut installing hole; Described nut comprises that the installation position is in the step of installation portion lower end, installation portion is installed in the nut installing hole, on the installation portion between step and upper reinforcing plate topmost cover buffer spring is arranged, installation portion be positioned at upper reinforcing plate topmost above card snap ring is arranged.By snap ring is set, nut can be installed on the upper connector reliably.By buffer spring is set, when down-hole hammer was subject to large impact force, buffer spring had the effect of buffering, therefore, can play the effect all of protection power.
As improvement, lower connector comprises lower sleeve and lower reinforcing plate, and lower reinforcing plate is located in the lower sleeve, and the second perforation is located on the lower reinforcing plate.The lower connection physical efficiency of this structure reduces consumptive material, and can improve the down intensity of connector after lower reinforcing plate is set.
As improvement, be provided with sealing ring between down-hole hammer and the lower reinforcing plate, energy mode water and dirt enter in lower connector and the upper connector, play the effect of protection down-hole hammer.
As improvement, described connector comprises connector and is located at the two resistance to deformation plates that are superimposed with each other of connector lower end.By two blocks of resistance to deformation plates are set, when connector was subject to large impact force, connector was not easy distortion, thereby had improved the intensity of connector.
As specializing, described fastener is the screw of radially installing.
