Abstract
The utility model discloses a rock test piece drilling and cutting machine for a split Hopkinson pressure bar (SHPB) test, which comprises a motor (1), a support (2), a rock cutting device (3), a base (4) and the like. The motor (1) is adjusted according to the position of the rock cutting device (3) on the support (2) for the first time of cutting of large-diameter rocks. Then, the large-diameter rocks which have been cut are placed on core drilling vises (15) on the base (4), and small-diameter (smaller than or equal to 50mm) rock cores are taken out. The small-diameter rock cores which have been taken out are placed on the rock cutting device (3) again to be cut into small-diameter (smaller than or equal to 50mm) rock test pieces with the length-diameter ratio smaller than 0.5. By adopting the small-diameter rock drilling and cutting machine with the structure, not only is the structure simple, but also the required small-diameter (smaller than or equal to 50mm) rock test pieces with the length-diameter ratio smaller than 0.5 can be obtained quickly with very low cost.
Description
Technical field
The present invention relates to the drilling through-cutting machine of rock sample in the rock impact dynamics field, what be specifically related to is to obtain needed length in separate type Hopkinson depression bar (the being called for short SHPB) experimental provision less than 0.5 minor diameter (≤50mm) rock sample device.
Background technology
In the deep mining engineering; Fields such as the antiknock design of large-scale underground chamber and structure; Must carry out the dynamic characteristics of rock; And its dynamic characteristic also is that numerous deep rock mass engineering projects bring out the key that the rock burst reason is analyzed, and it is significant therefore to study the dynamic mechanical of rock under percussion.What the dynamic mechanical of research rock mainly adopted at present is the SHPB experimental provision.
The SHPB experimental provision carries out the dynamic mechanical test to rock and the time faces the wave dispersion effect problem, for overcome influence that the wave dispersion effect causes experimental result need adopt minor diameter (≤50mm) and length less than 0.5 rock sample.The method that obtains rock sample at present all is to utilize minor diameter rock core drilling rig to drill through long core earlier, cuts into the rock sample that needs through the rock cutting machine again.Whole process is comparatively complicated, and the end product quality of test specimen is relatively poor, and two faces parallels of cylinder test specimen can not guarantee that end face is not easy to guarantee vertical each other with cylinder simultaneously.In addition, length less than 0.5 minor diameter (≤50mm) absolute thickness of rock sample is all smaller, equipment and the machine of making this test specimen at present in the common laboratory all are difficult to meet the demands.
Summary of the invention
The rock sample that is applicable to SHPB experiment drills through-and cutting machine is a kind of novel multifunctional device instrument, is used for when the Dynamic Rock Mechanics Performance Testing, obtaining length less than 0.5 minor diameter (≤50mm) rock sample.The purpose of this invention is to provide a kind of simple in structure, obtain ideal dimensions rock sample efficient is high, adaptability is good, experimental cost is low experimental provision and method.
The present invention realizes through following technical scheme: the rock sample that is applicable to the SHPB experiment drills through-cutting machine, comprises motor, rock cutting device, compositions such as base.Motor is made up of the gear that has turning handle, set bolt and rotor, and rotor both can have been installed the rock cutting blade also can install diamond thin-wall drill bit, can be dual-purpose, and the rotating speed of rotor can be through the speed-regulating switch adjustment simultaneously.Motor is according to the position of rock cutting device; Turning handle driven gear through adjusting gear; And then realize motor moving up and down on support through the transmission between gear and the tooth bar, regulate behind the position of motor to prevent that sliding up and down through set bolt of motor is fixed on motor on the support.Rock cutting device is formed by rotating turning handle, rotation chopping wheel, rock cutting vice, set bolt and up-down fixer, and the up-down fixer is equipped with the same gear that rotates turning handle that has with motor, can realize moving up and down of rock cutting device.Rock cutting device passes through to regulate the up-down fixer according to the position of motor, regulates the back and fixes whole cutter sweep with set bolt, rotates chopping wheel through turning handle then; Through the cutting of the rock on chopping wheel vice attachment rock; After fixing rock, rotor is installed the rock cutting blade, opens the speed-regulating switch on the motor; And the speed of regulating rotor is suitable value, cuts large diameter core through rotating chopping wheel then.Base is made up of the tooth bar on support, brill core vice and the support; Mounting bracket is used for assembling motor and rock cutting device on the base; The fixedly brill core vice of major diameter core is housed on base, after changing diamond thin-wall drill bit on the rotor, opens the speed-regulating switch on the motor; And the speed of regulating rotor moves up and down the core that motor takes out minor diameter through the turning handle on the adjusting gear then for suitable value.Be placed on the minor diameter rock of getting once more and carry out second time cutting on the rock cutting device, obtain length less than 0.5 minor diameter (≤50mm) rock sample.
Advantage of the present invention is: (two faces parallels of≤50mm) quality of finished product good of rock sample, and test specimen can be guaranteed less than 0.5 minor diameter can to obtain length; Adopt small-sized rock cutting device that rock is cut, adopt the motor of adjustable speed to prevent that core is in that to obtain the excessive core that causes of process medium velocity broken in when cutting; Be assemblied in small-sized rock cutting device on the minor diameter core drilling rig and the shared motor of core drilling rig simultaneously, thereby provide cost savings; Drilling through and cutting of realization minor diameter core is integrated, can high efficiency must obtain the core that needs size.

The specific embodiment
In Experimental equipment shown in Figure 1, support (2) is installed on the base (4), motor (1) be installed in support (2) above, rock cutting device (3) is installed on the support (2), is positioned between base (4) and the motor (1).
Motor in Fig. 2 (1), at first the position adjustments according to rock cutting device (3) arrives suitable position, fixes motor through set bolt (6) then.After motor (1) fixes; The rock cutting blade is installed on dual-purpose rotor (5) again; In Fig. 3, be fixed on rock on the rock cutting vice (11) then, after fixing, make rock near cutting blade through the turning handle (13) that rotates on the rock chopping wheel (12); Adjust up-down fixer (9) through the turning handle on the adjustment gear (8) again; Make and go up set bolt (7) with up-down fixer (9) at this moment and fix rock cutting device in the rock position that slice alignment will cut, prevent to move up and down.Start the switch of motor (1) then and regulate cutting blade speed, make that section speed is moderate, the turning handle (13) that rotates subsequently on the rock chopping wheel (12) carries out first step cutting rock.
After cutting all rocks; Forward rock chopping wheel (12) to one side; And unload the rock cutting blade; Install diamond core bit, the brill core vice of on Fig. 4 base, installing again after installing (15) is gone up the rock fixedly cut, regulates motor (1) and down slowly moves and get the core of minor diameter through the cog turning handle of (8) of rotary electric machine (1).Slow mobile motor (1) downwards when noting getting the core of minor diameter, firmly evenly, the speed that prevents is excessive get core broken.After taking out all minor diameter cores, be put into cutting length on the device of Fig. 3 to core less than 0.5 minor diameter rock sample again.
