Abstract
The utility model relates to a hole and rock drill, which comprises impacting devices and drilling rods connected with the impacting devices. The front end of each impacting device is connected with a drilling head and the tail end of each drilling rod is connected with a backward rotating device of the drilling rods by a drilling rod joint. A plurality of impacting devices are bound into integration by position sliding rings. The drilling heads of two contiguous impacting devices are in front and back staggered arrangement in a drilling direction. The drilling rod of the front part of each drilling rod joint is also provided with one position sliding ring of the drilling rods, which is used for binding the drilling rods together. The backward rotating device of the drilling rods comprises driving drilling rods provided with gears and fixedly connected with the drilling rod joints. The gears of two contiguous driving drilling rods are in the front and back staggered arrangement. The transmission of the gears of the driving drilling rods is conducted by a backward rotating motor arranged in a machine shell. The tail part of each driving drilling rod is connected with an air pressing and water supplying main pipe by mechanical seal joints. The hole and rock drill of the utility model can drill out a plurality of body connecting holes at one time with good guidance quality and high work efficiency and is particularly suitable for drilling deep holes. The utility model has wide application and can be suitable for the modern requirements of high speed and high efficiency.
Description
Technical field
The utility model relates to a kind of winning equipment, particularly a kind of exploitation rock down-the-hole drilling machinery.
Background technology
In the prior art, application number as the applicant's application is 011272236, publication number is the Chinese patent of CN1336269A, a kind of downhole rock drill with interior slewing equipment is disclosed, it is provided with casing, be provided with the beater mechanism of taking back rotation mechanism in the casing, the bit shank of beater mechanism piston nose inserts in the hole the drill steel of band bore bit is installed, the casing rear portion is provided with water inlet and flushing machine, the front end of beater mechanism is connected with the drill steel that is no less than two band bore bits side by side, the setting of staggering before and after on drilling direction of bore bit on adjacent two drill steels, the afterbody of every drill steel all is installed in different beater mechanism front ends respectively, beater mechanism is arranged side by side in the casing, and the rear end of each beater mechanism all is provided with interior slew gear.It is that a kind of hammer drill that utilizes gets out siamesed port on the ore body section, by siamesed port the periphery of the rock that will exploit is separated effective rock drilling machinery from whole ore body, the weak point of its existence is: its accumulator and oil gas are in charge of all in the hole, and structure is comparatively complicated; Owing to be the interior slew gear that adopts, rotating speed is non-adjustable in addition.
Summary of the invention
The technical problems to be solved in the utility model is, proposed the downhole rock drill of a kind of impactor at the drilling rod front end, and its can disposablely get out many siamesed ports.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of downhole rock drill, it comprises impactor and the drilling rod that is connected with impactor, the impactor front end is connected with drill bit, tail end at drilling rod is connected with the drilling rod slewing equipment by tool joint, be characterized in: be no less than three impactors and be bundled into an integral body by the location slip ring, the setting of staggering before and after on drilling direction of drill bit on adjacent two impactors, described location slip ring is to be enclosed within tubular body on the impactor shell by a row to be connected to each other and to form, the junction of this location slip ring between every adjacent tubular body is inlaid with the primary alloy bore bit on the end face of drill bit, on the drilling rod of each tool joint front portion, also be provided with the drilling rod location slip ring that drilling rod is bundled, described drilling rod slewing equipment comprises the kelly that has gear of fixedlying connected with tool joint, the setting of staggering before and after the gear on adjacent two kellies, gear on the kelly is by being arranged on the rotary motor transmission in the casing, the afterbody of kelly by the mechanical seal joint with calm the anger, the water main connects.
The utility model compared with prior art, being no less than three impactors is arranged side by side together, the setting of staggering before and after on drilling direction of drill bit on adjacent two impactors, down-the-hole drilling function of the present utility model is disposable to get out many siamesed ports, utilize rock drilling machine drill siamesed port of the present utility model, guidance quality is good, and high efficiency is particularly suitable for drilling deep hole.It is of many uses, can adapt to high-speed, the high efficiency requirement of modernization.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
A kind of downhole rock drill, it comprises impactor 3 and the drilling rod 4 that is connected with impactor 3, impactor 3 front ends are connected with drill bit 1, tail end at drilling rod 4 is connected with the drilling rod slewing equipment by tool joint 6, five impactors 3 are bundled into an integral body by locating sliding 2 rings, the setting of staggering before and after on drilling direction of drill bit 1 on adjacent two impactors, described location slip ring 2 is to be enclosed within tubular body on the impactor shell by a row to be connected to each other and to form, the junction of this location slip ring 2 between every adjacent tubular body is inlaid with primary alloy bore bit 11 on the end face of drill bit, on the drilling rod 4 of each tool joint 6 front portion, also be provided with the drilling rod location slip ring 5 that drilling rod is bundled, described drilling rod slewing equipment comprises the kelly that has gear 78 of fixedlying connected with tool joint 6, the setting of staggering of gear 7 front and back on adjacent two kellies, gear 7 on the kelly 8 is by being arranged on the rotary motor transmission in the casing, the afterbody of kelly 8 by mechanical seal joint 9 with calm the anger, water main 10 connects.The size of 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 drill bit of diameter, every adjacent hole, the hole that gets out crosses one another, when the drill bit of hysteresis creeps into, and the cavity that its both sides have pilot bit to get out, therefore the resistance that creeps into is little, so the bit diameter that lags behind can be designed as bigger slightly than leading drill bit.The drill bit that lags behind can adopt post jagged bit, crowned bit or cross bit; When rock is softer, broken easily, can adopt the less drill 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 drill bit, be easy to shatterly, its location primary alloy on slip ring just can be washed residual partition wall open.At the other guiding device that also is installed with side by side of one of them drill steel of both sides portion.Downhole rock drill of the present utility model, a plurality of impactors bundle side by side, and its mode in parallel can adopt a plurality of impactors in one line, is linear distribution, can beat rectilinear siamesed port by this device; Also can adopt the curved arrangement of a plurality of impactors, adopt this device can get curved siamesed port along design.
