[0034] Combination Figure 1-3 As shown, the suction cup 10-type gripper of the demolition device provided by the utility model includes:

[0035] A mounting arm 1, wherein a receiving groove 2 is provided inside the mounting arm 1, a bidirectional threaded rod 3 is rotatably connected inside the receiving groove 2, a mounting seat 4 is rotatably connected on the bidirectional threaded rod 3, and a mounting groove 5 is provided inside the mounting seat 4;

[0036] A clamping block 6 is clamped in the mounting groove 5, the interior of the clamping block 6 is slidably connected to a limit block 7, and an elastic rod 8 is fixedly connected to the side wall of the limit block 7;

[0037] The support frame 9 is fixedly connected to the side wall of the block 6 , a suction cup 10 is installed at the bottom of the support frame 9 , and an air guide tube 11 is installed on the top of the suction cup 10 passing through the support frame 9 .

[0038] The mounting arm 1 is mainly used to provide mounting support. According to the technical solution of the present application, the mounting arm 1 is mounted on the demolition equipment by means of bolts, so that objects (such as glass) can be adsorbed and fixed by the suction cup 10 during demolition.

[0039] According to the technical solution of the present application, the bidirectional threaded rod 3 is rotatably connected in the storage groove 2 through a bearing, and one end of the bidirectional threaded rod 3 is fixedly connected to a motor 12, which is installed on the mounting arm 1. The motor 12 is powered by an external power supply. Starting the motor 12 can drive the bidirectional threaded rod 3 to rotate forward or reverse.

[0040] Furthermore, the left and right sections of the bidirectional threaded rod 3 are arranged with opposite thread directions, and there are two mounting seats 4. The two mounting seats 4 are symmetrically arranged on the bidirectional threaded rod 3, and the two mounting seats 4 are respectively provided with threaded holes that are compatible with the bidirectional threaded rod 3. When the bidirectional threaded rod 3 rotates, the matching relationship between the threaded hole and the bidirectional threaded rod 3 can drive the two mounting seats 4 to move closer to or away from each other.

[0041] The mounting seat 4 and the clamping block 6 are mainly used for installing the suction cup 10. According to the technical solution of the present application, the mounting groove 5 and the clamping block 6 are adapted to each other. When the clamping block 6 is inserted into the mounting groove 5, it can be stably installed. It should be noted that through grooves adapted to the limit block 7 are provided on both sides of the clamping block 6. By using the provided through grooves, the Fang Boyi limit block 7 extends into the clamping block 6 and is inserted into the mounting groove 5 to prevent the clamping block 6 from detaching from the mounting groove 5.

[0042] According to the technical solution of the present application, there are multiple limit blocks 7, and every two limit blocks 7 are used in a group. The top of the limit blocks 7 is fixedly connected with a lever 13, and the top of the clamping block 6 is provided with a strip groove 14 adapted to the lever 13. The provided strip groove 14 facilitates the left and right movement of the lever 13. The lever 13 is driven to drive the two limit blocks 7 in the same group to approach each other to squeeze the elastic rod 8, which can drive the limit blocks 7 to be stored in the interior of the clamping block 6, thereby unlocking the clamping block 6 and the installation groove 5, making it easy to disassemble the clamping block 6, thereby facilitating the replacement of different types of grippers according to actual needs.

[0043] Furthermore, there are multiple elastic rods 8, and every two elastic rods 8 are used together as a group. The elastic potential energy provided by the elastic rods 8 can drive the two limit blocks 7 to reset.

[0044] Furthermore, there are multiple suction cups 10, and every four suction cups 10 are used in a group. The suction cups 10 are connected to a vacuum pump through an air duct 11 arranged on the top. The vacuum pump forms a negative pressure between the suction cups 10 and the object, so that the suction cups 10 can be tightly adsorbed on the object. The vacuum pump is powered by an external power supply.

[0045] Specifically, when it is necessary to adsorb an object, first install the mounting arm 1 on the demolition equipment by means of bolts, and then start the motor 12 to drive the bidirectional threaded rod 3 to rotate. When the bidirectional threaded rod 3 rotates, the adaptation relationship between the threaded hole and the bidirectional threaded rod 3 can drive the two mounting seats 4 to approach or move away from each other, thereby facilitating the adjustment of the specific positions of the two groups of suction cups 10, and facilitating adaptive adjustment according to the actual size of the object, thereby improving the applicability of the device. Then, the suction cup 10 is pressed against the surface of the object, and the suction cup 10 is evacuated with the help of an external vacuum pump to fix it on the object. When it is necessary to disassemble the suction cup 10 type gripper, first, move the lever 13 to drive the two limit blocks 7 of the same group to approach each other to squeeze the elastic rod 8, so as to drive the limit block 7 to be stored in the interior of the card block 6, thereby unlocking the card block 6 and the mounting groove 5, facilitating the disassembly of the card block 6, thereby facilitating the replacement of different types of grippers according to actual needs.
