A kind of high blast integral type down-the-hole drill
Technical field
The present invention relates to a kind of high blast integral type down-the-hole drill.
Background technology
What China's large medium-size mine strip mining transformation was all the time used is low blast, split type middle-size and small-size down-the-hole drill, and wide-aperture only have rotary drill, and efficient is low, and cost is high.The large-scale integral churn is by external rig monopolization.But external product is expensive, complex structure, maintenance difficult.Based on this, more domestic rig factory has also developed some integral type rigs, but there are some defectives in everyway, and complicated structure, inconvenient operation, and intensity is little.
Summary of the invention
The technical problem to be solved in the present invention is to provide the high blast integral type down-the-hole drill that an a kind of propelling stroke is large, intensity is high, easy to operate.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of high blast integral type down-the-hole drill, it comprises walking mechanism, dynamical system, drilling system, balladeur train, is installed on the turn-around machine on balladeur train and is installed on balladeur train to drive the propelling reduction box of turn-around machine motion, its key technology is: described balladeur train comprises sliding rack body, described sliding rack body both sides are equipped with slideway longitudinally, and described sliding rack body upper/lower terminal is positioned with chain wheel assembly; Described turn-around machine coordinates with slideway by the nylon jacket that is arranged in slide block;
Described sliding rack body is case structure, and its shape is divided into three sections, and wherein the longitudinal section of epimere is trapezoidal, the cross section is orthogonal, and longitudinal section, the cross section in stage casing are rectangle, and the longitudinal section of lower end, cross section are the size rectangle less than the stage casing.
Offer lightening hole on described sliding rack body.
Described slideway material is the entity square steel.
Described chain wheel assembly comprises a duplex chain wheel.
The beneficial effect that adopts technique scheme to produce is: sliding rack body of the present invention is case structure, and strength ratio is higher, can improve its propelling stroke, and the drilling depth of drilling rod can reach 14m-16m, and is middle without connecting and disconnecting drill rod; Turn-around machine relies on slide block movement on slideway, moves accurately and reliably, and good stability, Drilling efficient is high, and is easy to operate, and maintenance is easily.

The specific embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Referring to accompanying drawing 1-4, the present invention includes walking mechanism 4, vehicle frame mechanism 5, dynamical system 1, drilling system, hydraulic leg 3, dust pelletizing system 12, drivers' cab and operating-controlling mechanism 9, balladeur train, be installed on the turn-around machine 11 on balladeur train and be installed on the structures such as propelling reduction box 6 of moving to drive turn-around machine 11 on balladeur train, wherein crucial improvement is that the structure of balladeur train part is improved.Wherein advance reduction box 6 to drive duplex chain wheel 19-3 and drag turn-around machine 11, dependable performance.That dust pelletizing system 12 is furnished with is dried, wet-scrubbing equipment (optional) can be realized without dust work, has improved greatly the worker laboring environment.Walking mechanism 4 adopts the high power hydraulic motor to drive traveling retarding mechanism.Turn-around machine 11 adopts high-pressure and hydraulic motor dual-driving-mode.
Referring to accompanying drawing 5-10, described balladeur train comprises sliding rack body 14, described sliding rack body 14 both sides respectively are provided with a slideway 15 longitudinally, this slideway 15 adopts the entity square steel to make, described sliding rack body 14 upper/lower terminals respectively are positioned with between 19, two chain wheel assemblies 19 of a chain wheel assembly through duplex chain 20 transmissions; The two ends, base bottom of described turn-around machine 11 respectively are fixed with a slide block 17, are provided with nylon sliding sleeve 16 on slide block 17, and this nylon sliding sleeve 16 coordinates slip with slideway 15, and can regulate gap each other by bolt.
Referring to accompanying drawing 5 and accompanying drawing 7, described sliding rack body 14 is case structure, its planform is divided into three sections, wherein the longitudinal section of epimere B is trapezoidal, the cross section is orthogonal, longitudinal section, the cross section of stage casing C are rectangle, and the longitudinal section of hypomere D, cross section are also rectangle, but little than stage casing C of the size of hypomere rectangle, namely integral body goes to upper and lower the shape that is small at both ends and big in the middle.Longitudinal section herein refers to the section on short transverse, and the cross section refers to the section of horizontal direction.Offer lightening hole on described sliding rack body 14.Described slideway 15 materials are the entity square steel.Propelling stroke of this high strength balladeur train can reach 14M-16M, and overlength drilling rod pull length can reach 14M.
The present invention is a kind of advanced drilling equipment (KQ200D) that breach Drilling system and screw air compressor are combined together.Its compact conformation, good integrity, conveniently moving adapts to the outdoor cutting rig of large medium-size mine.Bore diameter: φ 152-φ 228 mm, drilling depth 14M (extension bar can hole 28M).It is large that the present invention has the Drilling aperture, and Drilling efficient is high, and is easy and simple to handle, keeps in repair the characteristics such as easy.
