Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] like Figures 1 to 3 As shown, the utility model provides a multi-angle crack preparation device for rock samples, including a base 1, a bracket 5 is fixedly connected to the top outer wall of the base 1, a first cylinder 6 is fixedly connected to the top outer wall of the bracket 5, a fixed plate 8 is fixedly connected to the movable end of the first cylinder 6, a second cylinder 7 is fixedly connected to the rear end outer wall of the fixed plate 8, a moving mechanism 3 is arranged on the inner wall of the fixed plate 8, a clamping mechanism 2 is arranged on the top outer wall of the base 1, the clamping mechanism 2 includes a rotating plate 201, and a plurality of groups of card slots 20 are arranged on the top outer wall of the rotating plate 201 2. The top outer wall of the rotating plate 201 is fixedly connected with a placing plate 203, and the top outer wall of the placing plate 203 is provided with a plurality of sliding grooves 205. The inner wall of the placing plate 203 is rotatably connected with a turntable 207, and the outer wall of the turntable 207 is provided with a plurality of arc grooves 208. The inner wall of the arc groove 208 is slidably connected with a clamping block 204. The outer wall of the turntable 207 is fixedly connected with a shifting block 206, and the inner wall of the shifting block 206 is elastically connected with a clamping block 210 through a spring A209. The top of the placing plate 203 is detachably installed with a rock sample 4.
[0023] The above scheme is adopted: by placing the rock sample 4 on the placement plate 203, and then pulling the clamping block 210 upward to make it out of contact with the clamping groove 202, the limit of the turntable 207 can be released, and the dial block 206 is turned to rotate the turntable 207, and the inner wall of the arc groove 208 generates a squeezing force on the outer wall of the bottom end of the clamping block 204, so that the clamping block 204 moves, and through the guiding effect of the slide groove 205, the clamping block 204 is kept in a state of linear motion in the slide groove 205, so that the four groups of clamping blocks 204 can be moved to the middle or outside at the same time by toggling the dial block 206, so that the four groups of clamping blocks 204 can clamp and fix the rock sample 4 at the same time, and then the first cylinder 6 can be started to drive the fixing plate 8 and the moving mechanism 3 to move downward, and by starting the second cylinder 7, the moving mechanism 3 can be driven to move back and forth, so that the surface of the rock sample 4 can be prepared for cracks through the drill bit 307.
[0024] like Figures 1 to 3 As shown, the rotating plate 201 is fixedly connected to the top outer wall of the base 1, the shifting block 206 passes through the side wall of the placement plate 203, one end of the spring A209 is fixedly connected to the top inner wall of the shifting block 206, and the other end of the spring A209 is fixedly connected to the outer wall of the clamping block 210, the outer wall of the clamping block 210 is slidably connected to the inner wall of the shifting block 206, the clamping block 210 is clamped with the clamping groove 202, the outer wall of the clamping block 204 is slidably connected to the inner wall of the slide groove 205, and the outer wall of the clamping block 204 contacts the outer wall of the rock sample 4.
[0025] The above scheme is adopted: by pulling the block 210, the spring A209 is forced to shrink, and the block 210 moves upward and disengages from the slot 202, and the shift block 206 can be moved to make the shift block 206 move laterally along the opening of the side wall of the placement plate 203, driving the turntable 207 to rotate, thereby driving the four groups of clamping blocks 204 to move toward the middle or outside at the same time. When the four groups of clamping blocks 204 are all moved to contact the side wall of the rock sample 4, the block 210 can be released, so that the spring A209 drives the block 210 to move downward and reset due to its own elastic force, and engages with one of the groups of slots 202, so that the position of the turntable 207 can be fixed, thereby fixing the position of the four groups of clamping blocks 204, and clamping and fixing the rock sample 4 more conveniently and quickly.
[0026] like Figure 5As shown, the moving mechanism 3 includes a moving block 308, the front end outer wall of the moving block 308 is fixedly connected to the motor 301, the output shaft of the motor 301 is fixedly connected to the rotating block 302, the outer wall of the rotating block 302 is provided with a through groove 303, the inner wall of the rotating block 302 is clamped with a connecting block 304, the inner wall of the connecting block 304 is slidably connected with two groups of limit blocks 306, the two groups of limit blocks 306 are elastically connected by a spring B305, the bottom end outer wall of the connecting block 304 is fixedly connected with a drill bit 307, the moving block 308 is slidably connected to the inner wall of the fixed plate 8, the movable end of the second cylinder 7 is fixedly connected to the rear end outer wall of the moving block 308, the two ends of the spring B305 are respectively fixedly connected to the outer walls of the two groups of limit blocks 306, and the limit blocks 306 are clamped with the through groove 303.
[0027] The above scheme is adopted: by starting the second cylinder 7, the moving block 308 can be driven to move horizontally forward and backward, and the motor 301 is started, so that the output shaft of the motor 301 drives the rotating block 302 to rotate synchronously with the connecting block 304 and the drill bit 307, so that the drill bit 307 can open a crack on the surface of the rock sample 4, and by pressing the limit block 306, the spring B305 is forced to shrink, so that the limit block 306 is out of contact with the through groove 303, the connecting block 304 and the drill bit 307 can be removed, and the appropriate drill bit 307 can be replaced according to the size or depth of the crack to be prepared. When installing the drill bit 307, the limit block 306 can be pressed inward, and the connecting block 304 can be inserted into the rotating block 302. When the position of the limit block 306 corresponds to the position of the through groove 303, the spring B305 can drive the limit block 306 to pop out to both sides due to the elastic force and engage with the through groove 303, so that the position of the connecting block 304 and the drill bit 307 can be fixed.
[0028] like Figure 4 As shown, the outer wall of the bottom end of the rotating plate 201 is fixedly connected with a bevel gear A901, the outer wall of the bevel gear A901 is meshed with a bevel gear B902, the outer wall of the bevel gear B902 is fixedly connected with a rotating rod 903, and the outer wall of the rotating rod 903 is rotatably connected to the inner wall of the base 1.
[0029] By adopting the above solution, the bevel gear B902 can be driven to rotate by rotating the rotating rod 903. Since the bevel gear A901 is meshed with the bevel gear B902, the bevel gear B902 can drive the bevel gear A901 to rotate when rotating, thereby driving the clamping mechanism 2 to rotate as a whole, so as to adjust the angle of the rock sample 4 and open cracks of different angles through the drill bit 307.
[0030] The working principle and use process of the utility model are as follows: when in use, the card block 210 can be pulled upward first, and the spring A209 is forced to shrink, so that the card block 210 is out of contact with a group of card slots 202, and then the shift block 206 is shifted counterclockwise, so that the shift block 206 drives the turntable 207 to rotate synchronously, and the inner wall of the arc groove 208 produces a squeezing force on the outer wall of the clamping block 204, so that the clamping block 204 moves. Since the slide groove 205 has a guiding effect on the clamping block 204, the clamping block 204 is kept in a state of linear motion in the slide groove 205, and can be moved synchronously to the outside. When the clamping block 204 moves to the outermost side, the card block 210 can be released, so that the spring A209 drives the card block 210 to pop out downward due to its own elastic force and engage with a group of card slots 202, limiting the turntable 207, thereby fixing the position of the clamping block 204.
[0031] Then the cut square rock sample 4 can be placed on the surface of the placement plate 203, and then the clamping block 210 can be pulled upwards, and the dial block 206 can be turned to make the turntable 207 rotate clockwise, which can drive the four groups of clamping blocks 204 to move toward the middle at the same time to clamp the rock sample 4. When the four groups of clamping blocks 204 are in contact with the outer wall of the rock sample 4, the turntable 207 and the clamping blocks 204 can be fixed by engaging the clamping block 210 with the card slot 202, so that the rock sample 4 can be clamped and fixed more conveniently and quickly, and the operation can be completed without moving the positions of the clamping blocks 204 one by one, saving time and effort.
[0032] After the rock sample 4 is fixed, the first cylinder 6 can be started to drive the fixing plate 8 and the moving mechanism 3 to move downward. When the drill bit 307 moves to contact the surface of the rock sample 4, the motor 301 can be started to drive the rotating block 302 to rotate. The rotating block 302 drives the connecting block 304 and the drill bit 307 to rotate synchronously. Then, the second cylinder 7 can drive the moving mechanism 3 to move forward and backward horizontally, so that cracks can be opened on the surface of the rock sample 4. When cracks of different angles need to be opened, the rotating rod 903 can be rotated to make the bevel gear B902 drive the bevel gear A901 to rotate, so that the clamping mechanism 2 can be rotated as a whole, and the placement angle of the rock sample 4 can be adjusted to open cracks of different angles.
[0033] When it is necessary to open cracks of different widths or depths, the drill bit 307 can be replaced. At this time, the two sets of limit blocks 306 can be pressed to disengage the limit blocks 306 from the through slots 303, and the connecting block 304 and the drill bit 307 can be removed, and then a suitable drill bit 307 can be selected for installation. During installation, the limit blocks 306 inside the connecting blocks 304 on the other set of drill bits 307 can be pressed inward, and the connecting block 304 can be inserted into the rotating block 302. When the positions of the limit blocks 306 and the through slots 303 correspond, the limit blocks 306 pop out to both sides due to the elastic force of the spring B305 and engage with the through slots 303, thereby completing the fixation of the drill bit 307 and quickly replacing the drill bit 307.
