Referring to fig. 1-3, the present invention provides a technical solution:

a core taking clamp special for hydraulic engineering quality detection comprises a sleeve body 1, a limiting ring 101 is arranged at the upper end inside the sleeve body 1, a compression column 2 is arranged on the upper side of the sleeve body 1, a pressing plate 201 is welded at the upper end of the compression column 2, a spring A202 is sleeved on the outer wall of the circumference of the compression column 2, the lower end of the compression column 2 penetrates through the outer wall of the sleeve body 1 to extend into the sleeve body 1 and is fixedly provided with a piston 203, a telescopic column 204 is arranged in the middle of the bottom surface of the piston 203, a connecting block 3 is arranged below the sleeve body 1, a hollow groove 301 is formed at the lower end of the connecting block 3, the lower end of the telescopic column 204 sequentially penetrates through the inner wall of the bottom surface of the sleeve body 1 and the inside of the connecting block 3 to extend into the hollow groove 301 and is welded with a conical block 205, two adjusting blocks 4 are symmetrically and rotatably connected inside the hollow groove 301 through a pin shaft, a sliding column 401 is welded at the upper end of each adjusting block 4, a square groove 402 is formed at the inner side of each adjusting block 4, a fixing column 403 is arranged inside the square groove 402, a clamping head 404 is arranged at the lower end of each adjusting block 4, the inner wall of the clamping head 404 is provided with anti-slip threads 405 at equal intervals, and a spring B406 is arranged below the conical block 205. Closely cooperate between the structure for inside the device can stretch the drilling grooving, cliied the core appearance through chuck 404, improved the efficiency of getting, avoided the condition that the used manpower and materials can be wasted to relapse sled, avoided the sled perk of relapse to lead to the fact the condition of damaging to the core appearance simultaneously.

Specifically, the upper end of the spring a202 is fixedly connected to the bottom surface of the retainer ring 101, and the lower end of the spring a202 is fixedly connected to the upper surface of the piston 203. The spring A202 is arranged so that the piston 203 can be pulled to reset by the pulling of the spring A202, and the conical block 205 is driven to reset.

Further, the outer circumferential wall of the piston 203 is slidably connected with the inner wall of the sleeve body 1. Carry out effectual spacing to piston 203 through the internal wall of cover barrel 1, make it can carry out displacement from top to bottom, and there is frictional force piston 203 and the internal wall of cover barrel 1 for centre gripping and reseing can slowly go on, can not damage core appearance because the power that the striking produced.

Still further, the outer wall of the conical block 205 is slidably connected with the circumferential outer wall of the sliding column 401. By sliding the conical block 205 and the circumferential outer wall of the sliding column 401, the angle of the conical block 205 to the chuck 404 and whether to clamp the chuck can be effectively controlled through different circumferential surfaces.

Furthermore, one end of the spring B406 is hooked and matched with the fixing column 403 positioned on the outer side through a hook, and the other end of the spring B406 is hooked and matched with the fixing column 403 positioned on the inner side through a hook. So that when the circumference of the conical block 205 is reduced, the collet 404 can be opened by pulling the spring B406 inward.

The working principle is as follows: when needing this hydraulic engineering quality to detect special core clamp, firstly, go deep into connecting block 3 in the drilling grooving, when the core appearance is between chuck 404, through pressing down clamp plate 201, because 2 lower extremes of compression leg pass set barrel 1 outer wall and extend to inside and have set firmly piston 203, piston 203 bottom surface middle part is equipped with flexible post 204, flexible post 204 lower extreme passes set barrel 1 bottom surface inner wall and connecting block 3 inside in proper order and extends to inside dead slot 301 and welding has conical block 205, and conical block 205 outer wall and traveller 401 circumference outer wall sliding connection, slide through conical block 205 and traveller 401 circumference outer wall, make it make chuck 404 carry out the centre gripping through conical block 205 large circumference, and piston 203 circumference outer wall and barrel 1 inner wall sliding connection. The piston 203 is effectively limited by the inner wall of the sleeve body 1 to be capable of moving up and down, friction force exists between the piston 203 and the inner wall of the sleeve body 1, so that clamping and resetting can be carried out slowly, a core sample cannot be damaged by force generated by impact, after the core sample is taken out, the pressing plate 201 is loosened, the lower end of the spring A202 is fixedly connected with the upper surface of the piston 203 due to the fact that the upper end of the spring A202 is fixedly connected with the bottom surface of the limiting ring 101, the spring A202 is arranged, the spring A202 can pull the piston 203 through the spring A202 to enable the piston 203 to be pulled to reset, so that the conical block 205 is driven to reset, one end of the spring B406 is in hanging fit with the fixed column 403 positioned on the outer side through the hook, the other end of the spring B406 is in hanging fit with the fixed column 403 positioned on the inner side through the hook, and after the circumferential surface of the conical block 205 is reduced, the chuck 404 can be opened through inward pulling of the spring B406, at this time, the core sample may be removed.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
