Background technology
In underground mine was produced, rock drilling equipment was one of three large main body production equipments, and the technological progress of rock drilling equipment has directly promoted the raising of the mine level of production, so require also more and more higher to the practicality of rock drilling equipment.Dynamical system and hydraulic pressure, electric system etc. that rock drilling equipment generally includes chassis system, operating mechanism, clamp mechanism and power is provided, clamp mechanism also is absolutely necessary as an annex of rock drilling equipment, clamp mechanism in existing market is handled more loaded down with trivial details, can't guarantee that the center of drill steel remains unchanged when the loading and unloading drill steel, these have directly affected the speed of loading and unloading drill steels, and then have affected mine production efficiency.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of mine drilling driving clamp mechanism, drill steel can load and unload quickly and easily in this mechanism in the mine drilling driving, the centering guide function is arranged, and realize fast the loading and unloading of drill steel, simple to operate, efficient improves.
for solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of mine drilling driving clamp mechanism, it is characterized in that comprising the clamping device seat, the claw I, the claw II, fixture block, clamping cylinder, stub axle and guide blot, the end of described claw I and claw II is two semicircle loop configuration that are oppositely arranged, be connected with fixture block between its end annulus, the claw I is connected with the cylinder body end of clamping cylinder, the claw II is connected with the telescopic end of clamping cylinder, claw I and claw II are installed on the clamping device seat by the stub axle, described guide blot is fixedly installed on the clamping device seat, the center of its axis and claw I and claw II is in same perpendicular.
Said structure is described further, is connected with two fixture blocks arranged side by side between described claw I and claw II, be bolted between fixture block and claw.
Said structure is described further, and described clamping device seat is provided with two stub axles, and each stub axle is connected with the claw II with the claw I respectively.
The beneficial effect that adopts technique scheme to produce is: be installed with guide blot in (1) the present invention, described guide blot plays the effect of guide-localization when claw I, claw II closure, the center after claw I, claw II closure of having guaranteed overlaps all the time and the position of relatively described clamping device seat can not change, and has realized the centering guiding; (2) in the present invention the two ends of clamping cylinder respectively pivotable be installed on described claw I, claw II, only need to handle the flexible loading and unloading that can realize drill steel of clamping cylinder, operation becomes very simple, efficient improves greatly.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is front view of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the top view of Fig. 2;
Wherein: 1, clamping device seat; 2, claw I; 3, claw II; 4, fixture block; 5, clamping cylinder; 6, stub axle; 7, guide blot.
The specific embodiment
1-3 as can be known with reference to the accompanying drawings, the utility model is specifically related to a kind of mine drilling driving clamp mechanism, comprise clamping device seat 1, claw I 2, claw II 3, fixture block 4, clamping cylinder 5, stub axle 6 and guide blot 7, the end of claw I 2 and claw II 3 is two semicircle loop configuration that are oppositely arranged, be connected with fixture block 4 between its end annulus, claw I 2 is connected with the cylinder body end of clamping cylinder 5, claw II 3 is connected with the telescopic end of clamping cylinder 5, claw I 2 and claw II 3 are installed on clamping device seat 1 by stub axle 6, guide blot 7 is fixedly installed on clamping device seat 1, the center of its axis and claw I 2 and claw II 3 is in same perpendicular, the relatively described clamping device seat in center that has guaranteed the drill steel that clamps can not change, the claw I, the claw II is by a hydraulic oil cylinder driving, make the manipulation of loading and unloading drill steel more efficient and convenient.
Be connected with two fixture blocks arranged side by side 4 between claw I 2 and claw II 3, be bolted between fixture block 4 and claw, clamping device seat 1 is provided with two stub axles 6, and each stub axle 6 is connected with the claw II with claw I 2 respectively and is connected.
In the utility model, claw I 2, claw II 3 are installed on clamping device seat 1 by stub axle 6 pivotables, are rotating centered by stub axle 6 under the driving of clamping cylinder 5.In the utility model, clamping cylinder 5 one end pivotables are installed on claw I 2, and other end pivotable is installed on claw II 3, makes stretching motion under the driving of hydraulic power source, realizes the closed action of claw I 2 and claw II 3, also namely drill steel are clamped and unclamp action.
in the utility model, guide blot 7 is fixedly installed in clamping device seat 1, its center and claw I 2, the center of claw II 3 is at same perpendicular, due to claw I 2, claw II 3 is impossible Complete Synchronization when closed, and because the wearing and tearing of bearing pin or fixture block 4 may cause claw I 2, claw II 3 or height relative clamping device seat 1 inconsistent at the center of short transverse changes, in claw I 2, when claw II 3 is closed, guide blot 7 plays the effect of guide-localization, guaranteed claw I 2, center after claw II 3 closures overlaps all the time and the position of relative clamping device seat 1 can not change.
The present invention compared with prior art has following significant progress:
