Abstract
The invention discloses a drill rod chuck for a hydraulic rock drilling rig. The drill rod chuck comprises a ring flange (1) and a drill rod chuck (3) fixed on the ring flange (1), wherein a groove position for placing a drill rod (5) is arranged on the circumferential edge of the drill rod chuck (3). The drill rod chuck is characterized in that the groove position is semicircular; at least one clamping spring (2) is arranged on each of two sides of the groove position; the tail end of each clamping spring (2) is of a smooth circular structure; each smooth circular structure extends out of the drill rod chuck (3) and presses the drill rod (5). During actual work, quick prolapse and buckle of the drill rod (5) can be directly realized under the action of an external force (F); when the drill rod (5) is buckled into the drill rod chuck (3), the drill rod cannot swing due to the fact that the drill rod is tightly attached to the inside of the groove position of the drill rod under the action of the clamping springs (2) and the swing and the wear of the drill rod (5) in a drill rod bin are effectively prevented.

Technical field
The present invention relates to rock drilling equipment part field, relate in particular to a kind of hydraulic rock drilling machine drilling rod chuck.
Background technology
External hydraulic rock drilling machine manufacturing technology is quite ripe, if Tom Luo Ke company of A Telasi ﹒ Atlas Copco company, Sandvik AB and the Finland of Sweden etc. is all the R&D and promotion of being devoted to hydraulic rock drilling machine and hydraulic rock machine technology always, its technical level is the status in holding a safe lead in the world today.Last century Mo remote-controlled problem of rock-drilling robot technology and product also take the lead in western countries especially Europe start exploitation.Robofore series, the Robot-Boom series of A Telasi ﹒ Atlas Copco company of Sweden and the Datamatic of Tom Luo Ke company of the Finland series problem of rock-drilling robot of current French Montabert Roger come into operation.
Aspect hydraulic rock drilling machine structure design and manufacturing technology, domestic starting is later than abroad, start the research of hydraulic impact mechanism in 20 century 70s, in overall technology, also lag behind Foreign Advanced Lerel, developed First hydraulic gate model machine YYG-80 in 1973 by Changsha Mine Inst, after the experiment and improvement of several years, pass through national ministerial level qualification in September, 1980.What at present participate in hydraulic gate technical research in China has Northeastern University, Central South University, Changsha Mine Inst, University of Science & Technology, Beijing, Beijing Coal research institute, Shenyang Pneumatic Tools Factory, an Xuanhua Pneumatic Tools Factory Deng10Duo Ge unit, develop the hydraulic gate of the different styles of kind more than 20, electric automatization and intelligent aspect, the He Qinghua of Central South University professor and team thereof are obtaining some positive achievements aspect the research of the intelligent problem of rock-drilling robot for tunneling.
In recent years, along with range of application becomes more and more extensive, and the development of Electric automation technology and Advanced Control Techniques and application, hydraulic rock drilling equipment is also more and more higher to the requirement of automation, such as requiring certainly to move bar, automatically walk, borehole location etc. automatically.But, because rock drilling equipment is all high pressure, high-strength working, when automatic job, must possess very high precision and stability, otherwise very easily cause the damage of component.
Summary of the invention
The object of the present invention is to provide a kind of drilling rod to pick and place conveniently, drilling rod is installed good, the nonabradable chuck structure of rear stability.
For reaching above object, the present invention adopts following technical scheme.
A kind of hydraulic rock drilling machine drilling rod chuck, comprising: flange, be fixed on the drilling rod dish on flange, and be provided with the groove position of placing drilling rod on the week edge of drilling rod dish; It is characterized in that, described groove position semicircular in shape, is respectively equipped with at least one clamp springs in the both sides of groove position; Described clamp springs end is smooth circular configuration, and this smooth circular configuration reaches outside drilling rod dish and is pressed on drilling rod.
As the further improvement of such scheme, between adjacent two groove positions, be provided with a U-shaped clamp springs, two ends of this U-shaped clamp springs bend the opening that blocks adjacent two groove positions outwardly.
As the further improvement of such scheme, described clamp springs is fixed by screws on drilling rod dish.
As the further improvement of such scheme, be provided with fixed cylinder in the centre of flange, on drilling rod dish, be provided with the waist-shaped hole matching with fixed cylinder, flange and drilling rod dish are fixed by screw.
As the further improvement of such scheme, be provided with at the outer wall of fixed cylinder and the inwall of waist-shaped hole the left hand thread matching.
Hydraulic rock drilling machine provided by the invention has following beneficial effect with drilling rod chuck:
One, by being respectively equipped with at least one clamp springs in the both sides of groove position, under the effect of clamp springs, be tightly attached in drilling rod groove position and do not occur the situation of drill pipe wobbling, effectively prevent that drilling rod from swinging in drilling rod storehouse, it is good, not easy to wear that drilling rod is installed rear stability.
Two, because the end of clamp springs is arranged to smooth circular configuration, under the effect of external force, can directly realize fast deviating from and buckling into of drilling rod, pick and place easy for installation.
Three, be provided with by the inwall of the outer wall in fixed cylinder and waist-shaped hole the left hand thread matching, can be by directly fixing from threaded between flange and drilling rod dish; Meanwhile, the design of left hand thread, makes hydraulic rock drilling machine when work, there will not be to rotate to come off between flange and drilling rod dish, simple in structure, practicality good.

Detailed description of the invention
Understand better essence of the present invention for further facilitating those of ordinary skill in the art, below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
As shown in Figure 1, a kind of hydraulic rock drilling machine drilling rod chuck, comprising: flange 1, be fixed on the drilling rod dish 3 on flange 1, and be provided with the groove position of placing drilling rod 5 on the week edge of drilling rod dish 3; It is characterized in that, described groove position semicircular in shape, is respectively equipped with at least one clamp springs 2 in the both sides of groove position; Described clamp springs 2 ends are smooth circular configuration, and this smooth circular configuration reaches outside drilling rod dish 3 and is pressed on drilling rod 5.
Like this, when real work, under the effect of external force F, can directly realize deviating from fast and buckling into of drilling rod 5, and after drilling rod 5 buckles into drilling rod dish 3, under the effect of clamp springs 2, be tightly attached in drilling rod groove position and do not occur the situation of drill pipe wobbling, effectively overcoming that drilling rod 5 swings in drilling rod storehouse and the problem of serious wear.
