The specific embodiment
Embodiment one, a kind of hammer drill, it is provided with casing 11, nine beater mechanisms 10 have been arranged side by side in the casing 11, all be separately installed with the drill steel 6 of band bore bit 2 in the bit shank patchhole 9 of each beater mechanism front end, casing 11 rear portions are provided with the flushing water inlet, the setting of staggering before and after on drilling direction of bore bit on adjacent two drill steels, outer slewing equipment is adopted in the revolution of drill steel, outer slewing equipment is arranged in the casing 11 of beater mechanism 10 front ends, described outer slewing equipment adopts the gear train of hydraulic motor 12 drives that are arranged in the casing to constitute, the tail end of every drill steel all slip cap be equipped with and change pricker gear 8, change pricker gear 8 and be provided with the drive sleeve that has interior hexagonal hole that matches with drill steel, the drive sleeve of changeing pricker gear 8 is installed in the casing 11 by bearing 7, pricker on adjacent two drill steels changes settings of staggering of gear 8 front and back, and the commentaries on classics pricker gear on every two drill steels separately is by an idler gear drive.All be provided with location convex shoulder 5 at every drill steel near the bore bit place, location convex shoulder 5 on every drill steel at grade, between drill steel convex shoulder 5 and bore bit 2, be provided with the location slip ring 4 of slip cap on drill steel, described location slip ring 4 is to be enclosed within tubular body on the drill steel by a row to be connected to each other and to form, junction between every adjacent tubular body is inlaid with primary alloy bore bit 1 on the end face of bore bit, also be provided with the short slip ring 3 of slip cap on drill steel between the bore bit of every long drill steel and location slip ring.Take out of outside the hole owing to will rely on bore bit will locate slip ring after boring finishes, be threaded so can only adopt between bore bit and the drill steel.The size of drill bit diameter is relevant with the character of rock, when rock is hard, in order to allow the location slip ring pass through smoothly, should select the bigger bore bit of diameter, the every adjacent hole of drilling bore hole crosses one another, when the bore bit of hysteresis creeps into, and the cavity that its both sides have leading bore bit to get out, therefore the resistance that creeps into is little, so the drill bit diameter that lags behind can be designed as bigger slightly than leading bore bit.The bore bit that lags behind can adopt post profile of tooth bore bit, turriform bore bit or bull bit; When rock is softer, broken easily, can adopt the less bore bit of diameter, the hole that get out this moment does not intersect, and a little partition wall is arranged between adjacent boring, because rock is softer, under the impact of bore bit, be easy to shatterly, its location primary alloy on slip ring just can be washed residual partition wall open.The front portion of drill steel is provided with corrugated thread, so that installation bore bit, the a bit of drill steel in the back of screw thread is processed into smooth cylinder, so that be slidingly matched with location slip ring formation, be provided with the shank collar that promotion location slip ring advances in cylindrical back, because bore bit requires to be staggeredly arranged, so drill steel length has two kinds of specifications, for each stress point stress balance when promoting the location slip ring, the shank collar that requires each drill steel is in same plane, mechanical balance in order to withdraw from, the afterbody of front-seat bore bit is equipped with short slip ring.The anterior construction of drill steel also can be taked the extension bar scheme, needs to make one section short drill steel this moment, and the tailing screw flight of short drill steel cooperates with branch sleeve, and the front end screw thread of short drill steel is connected with bore bit, and the cylinder that matches with the location slip ring is arranged on the short drill steel.Utilize branch sleeve to replace the shank collar that promotes the location slip ring.The centre of drill steel and afterbody are to be made by the rock-drill steel of hexagonal hollow, the afterbody shank collar is the same with common drill steel, but bit shank is longer, is to be staggered because change the pricker gear, this is because the distance between the adjacent drill steel is very near, is staggeredly arranged in order to make full use of the confined space.Beater mechanism adopts hydraulic-driven or pneumatic actuation.After rig got out a round, during second round that continue to bore links to each other, parallel in order to ensure with first round was at the other guiding device that also is installed with side by side of one of them drill steel of both sides portion.Described guiding device comprises a guide ring 14 of fixedlying connected with location slip ring 4, is equipped with in the guide ring 14 and drill steel guide peg 13 side by side.The afterbody of casing is provided with shared water supply hole and shared air vent or oil supplying hole.
Embodiment two, and described guiding device comprises the guide pad 15 that is arranged on slip ring edge, location and be filled in the interior ways 16 of edge hole that links to each other that described ways 16 is provided with the gathering sill 17 that is slidingly matched with guide pad.After having bored a round, in the edge hole of drilling bore hole, be filled with ways, at the edge that guide pad is installed in the location slip ring.When boring second round, guide pad advances along ways, plays the effect of guiding.Hammer drill of the present utility model, the drill steel that has beater mechanism is arranged side by side together, and its mode in parallel can adopt many drill steels in one line, is linear distribution, can beat rectilinear siamesed port by this device; Also can adopt the curved arrangement of many drill steels, adopt this device can get curved siamesed port along design.
