[0022] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0023] Embodiment 1

[0024] This embodiment provides a technical solution: a pneumatic negative pressure stone transport suction cup, such as Figure 1-4 As shown, it includes a first telescopic rod 1 and an anti-breaking positioning mechanism 2;

[0025] The anti-break positioning mechanism 2 is fixedly connected to the telescopic end of the first telescopic rod 1. The anti-break positioning mechanism 2 is used to measure the center point of the stone. The anti-break positioning mechanism 2 includes a limit box 201 fixed to the telescopic end of the first telescopic rod 1 and a rack 202 arranged at the bottom of the first telescopic rod 1. A gear 203 is rotatably installed in the limit box 201. Two racks 202 are provided. The two racks 202 are symmetrical about the central axis of the gear 203. The two racks 202 are meshed with the gear 203. The two racks 202 are slidably inserted into the limit box 201. The limit box 201 can fix the gear 203. At the same time, the limit box 201 can limit the two racks 202 to prevent the racks 202 from disengaging from the gear 203. The two racks 2 02, a spring 204 is fixed between them, the center of the spring 204 is fixed to the bottom surface of the limit box 201, and the two ends of the spring 204 are fixedly connected to the opposite side walls of the two racks 202. When the spring 204 is stretched by the two racks 202, the forces applied by the spring 204 to the two racks 202 are of the same magnitude and opposite directions. The spring 204 can reset the two racks 202, and four rollers 205 are rotatably installed at the bottom of each rack 202. Belts 206 are sleeved on the two rollers 205 on the same side. The belts 206 are forced to drive the rollers 205 to rotate, which can reduce the force between the belts 206 and the side walls of the stone to prevent the stone from breaking. The two belts 206 away from the pulley 4 are lower than the other two belts 206.

[0026] Furthermore, the first telescopic rod 1 is fixed to the bottom surface of the support frame 3 , and the support frame 3 can fix the first telescopic rod 1 .

[0027] Furthermore, a pulley 4 is fixed to the bottom of the support frame 3. By pushing the support frame 3, the support frame 3 can give thrust to the pulley 4. The rotation of the pulley 4 can drive the support frame 3 to move, making it convenient for the support frame 3 to drive the first telescopic rod 1 to move.

[0028] Furthermore, a universal wheel 5 is installed at the bottom of the support frame 3 through the rotation of the rotating frame. The movement of the support frame 3 can drive the universal wheel 5 to rotate. At the same time, the universal wheel 5 can change the forward direction and adjust the moving direction of the support frame 3. In order to keep the center of gravity of the entire device unstable and cause overturning, a heavy object can be placed on the support frame 3 according to the weight of the stone.

[0029] When in use, the support frame 3 is pushed to apply thrust to the pulley 4 and the universal wheel 5, and the pulley 4 and the universal wheel 5 rotate to drive the support frame 3 to move, and the support frame 3 drives the first telescopic rod 1 to move, and the first telescopic rod 1 drives the anti-breaking positioning mechanism 2 to move, so that the gap between the two belts 206 closer to the pulley 4 is aligned with a corner of the stone, and the support frame 3 is continued to be pushed to drive the anti-breaking positioning mechanism 2 to move, so that the edges of the two belts 206 closer to the pulley 4 squeeze a corner of the stone, and the other two belts 206 move toward an angle opposite to this angle, the stone is fixed, the two belts 206 closer to the pulley 4 are blocked, the two belts 206 closer to the pulley 4 fix the two rollers 205 connected to them, and these two rollers 205 are connected to a rack 20 2 is fixed, the limit box 201 keeps moving, the limit box 201 drives the gear 203 to move, the gear 203 is meshed with the rack 202, the gear 203 is pulled by a rack 202 to rotate, a rack 202 away from the support frame 3 moves in the direction away from the support frame 3, a rack 202 away from the support frame 3 drives the roller 205 connected thereto to move, the roller 205 drives the belt 206 connected thereto to move, when the belts 206 at the bottom of the two racks 202 are respectively in contact with the two opposite corners of the stone, the two racks 202 stretch the spring 204, and the suction cup 601 is at the top of the middle part of the stone, and the anti-breakage positioning mechanism 2 is driven to descend by the extension of the first telescopic rod 1, and the belts 206 at the bottom of the two racks 202 are stuck on the two opposite corners of the stone.

[0030] The process of the first telescopic rod 1 extending and retracting to drive the anti-breakage positioning mechanism 2 to descend and rise is that the first telescopic rod 1 drives the limit box 201 to descend and rise, the limit box 201 drives the gear 203 and the rack 202 to descend and rise, the rack 202 drives the spring 204 and the roller 205 to descend and rise, and the roller 205 drives the belt 206 to descend and rise.

[0031] Embodiment 2

[0032] This embodiment is further optimized on the basis of the above embodiment, and the same parts as the above technical solution will not be repeated here. Figure 3 As shown, in order to better realize the utility model, the following setting method is particularly adopted: in this embodiment, the bottom of the anti-break positioning mechanism 2 is welded with an adsorption component 6, and the adsorption component 6 is used to adsorb the surface of the stone. The adsorption component 6 includes a suction cup 601 arranged at the bottom of the anti-break positioning mechanism 2 and a pneumatic negative pressure device 602 fixed to the side wall of the support frame 3. The top of the suction cup 601 is fixed with a second telescopic rod 603 and a negative pressure tube 604. The suction cup 601 can be adsorbed on the surface of the stone, and the end of the negative pressure tube 604 away from the suction cup 601 is fixedly connected to the pneumatic negative pressure device 602;

[0033] By starting the second telescopic rod 603 to drive the suction cup 601 to descend, the suction cup 601 presses the top surface of the stone, and by starting the pneumatic negative pressure device 602, the pneumatic negative pressure device 602 can generate negative pressure suction, and the negative pressure suction is connected to the inside of the suction cup 601 through the negative pressure pipe 604, so that negative pressure suction can be generated between the suction cup 601 and the surface of the stone, and the suction cup 601 can be fixed to the stone, so that the stone can be sucked up conveniently. By contracting the first telescopic rod 1, the second telescopic rod 603 descends at the same time, and the first telescopic rod 1 drives the anti-breakage positioning mechanism 2 The anti-breakage positioning mechanism 2 drives the adsorption component 6 to rise, and at the same time, the second telescopic rod 603 drives the suction cup 601 to descend, and the suction cup 601 can remain motionless. Relative sliding occurs between the belt 206 and the stone. The edge of the stone gives friction to the belt 206. The belt 206 drives the roller 205 to rotate, and the belt 206 can rotate. The friction between the belt 206 and the stone is reduced to prevent the belt 206 from damaging the edge of the stone. After the belt 206 is separated from the stone, the spring 204 can drive the two racks 202 to reset.

[0034] The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences can be made to the spirit and scope defined by the claims of the utility model, but they will all fall within the scope of protection of the utility model.
