[0002] When preparing pig iron samples in steel plants, drill chips are drilled on hot-pressed iron blocks through a drill rig. The hot-pressed iron blocks are small pieces with a size of about 10*5cm. When preparing samples, the drill chips need to be drilled out, and the clamps that come with the drill rig cannot fix them well. When drilling samples, the hot-pressed iron blocks are easy to rotate and fly out, posing a safety hazard. At the same time, the drill chips also fly with the hot-pressed iron blocks and scatter on the operating table and cannot be collected and used, affecting sample inspection. Summary of the invention

[0015] 4. By providing latch teeth on the pneumatic clamp and the manual clamp, the friction between the manual clamp and the pneumatic clamp and the hot pressed iron block is increased, thereby further improving the clamping force of the hot pressed iron block to prevent it from rotating during drilling.

[0016] 5. The pneumatic clamp is driven to move by the pneumatic switch foot valve and SC cylinder, which is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] There are two slide bars 5 , and the two slide bars 5 are symmetrically located between the fixing plate 3 and the supporting plate 4 .

[0023] The slide bar 5 is used to pass through the pneumatic clamping plate 6 and the manual clamping plate 7 so that they are limited on the slide bar 5.

[0024] The clamping sides of the pneumatic clamping plate 6 and the manual clamping plate 7 are both provided with latch teeth 12 , the bottom ends of the pneumatic clamping plate 6 and the manual clamping plate 7 are both welded with two protrusions 13 , and the pneumatic clamping plate 6 and the manual clamping plate 7 are both provided with two through holes 14 .

[0025] The clamping teeth 12 are used to clamp the edge of the hot briquette, thereby increasing the friction between the manual clamping plate 7 and the pneumatic clamping plate 6 and the hot briquette, further improving the clamping force of the hot briquette to prevent it from rotating during drilling. The protrusion 13 is used to limit the pneumatic clamping plate 6 and the manual clamping plate 7 on the strip groove 2 so that they can slide along the strip groove 2.

[0026] The positions of the through holes 14 on the pneumatic splint 6 and the manual splint 7 correspond to the positions of the slide rod 5. The two slide rods 5 pass through the corresponding through holes 14 on the pneumatic splint 6 and the manual splint 7. The slide rod 5 is slidably connected to the pneumatic splint 6 and the manual splint 7 through the through holes 14. The pneumatic splint 6 is located at one end of the slide rod 5 close to the support plate 4, and the manual splint 7 is located at one end of the slide rod 5 close to the fixed plate 3.

[0027] The position of the protrusion 13 at the bottom end of the pneumatic splint 6 and the manual splint 7 corresponds to the position of the strip groove 2. The protrusion 13 at the bottom end of the pneumatic splint 6 and the manual splint 7 are respectively inserted into the two strip grooves 2, and the pneumatic splint 6 and the manual splint 7 are slidably connected to the strip groove 2 through the protrusion 13.

[0030] The working principle of the utility model is:

[0031] The appearance of the hot-pressed iron block is not uniform, and the shapes are large and small. When fixing it, it needs to be located in the center of the drilling platform 1 to face the drill bit, so as to facilitate drilling of drill cuttings. When in use, the air inlet end of the pneumatic switch foot valve 9 is connected to the compressed air pipe 10 at the work site, and several top blocks 11 of different sizes are prepared, and the appropriate top block 11 is selected according to the size of the hot-pressed iron block to be drilled for drill cuttings, and the top block 11 is placed between the manual clamping plate 7 and the fixed plate 3, so as to support the manual clamping plate 7. At this time, the hot-pressed iron block is placed between the manual clamping plate 7 and the pneumatic clamping plate 6, and the pneumatic switch foot valve 9 is stepped on to extend the SC cylinder 8 and push the pneumatic clamping plate 6 to move, so that the manual clamping plate 7 and the pneumatic clamping plate 6 tightly clamp the hot-pressed iron block, and the clamping teeth 12 clamp the edge of the hot-pressed iron block, thereby increasing the friction between the manual clamping plate 7 and the pneumatic clamping plate 6 and the hot-pressed iron block, further improving the clamping force of the hot-pressed iron block to prevent it from rotating during drilling.

[0032] At this time, the drilling platform 1 is operated to drill the hot briquette. After the drilling is completed, the pneumatic switch foot valve 9 is released to retract the SC cylinder 8 and drive the pneumatic clamp 6 to move, thereby releasing the hot briquette. At this time, the drill cuttings are collected to complete the preparation of the pig iron sample. When a hot briquette with a larger volume is fixed, a smaller top block 11 is replaced. Conversely, when a hot briquette with a smaller volume appears, a larger top block 11 is replaced, thereby ensuring that the hot briquette is in the central position of the drilling platform 1.
