DETAILED DESCRIPTION

[0030] The following is a further detailed description of an adjustable pipe segment sucker machine proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description and claims.

[0031] See also Figure 1 In one embodiment, an adjustable pipe segment suction cup machine includes: a lifting plate 2, a frame 1, a first suction cup 3, a second suction cup 4, a third suction cup 5, a vacuum part 6, and a control unit. The lifting plate 2 is arranged at the upper end of the frame 1, and one end of the lifting plate 2 is connected to an external crane.

The suction surfaces of the first suction cup 3, the second suction cup 4 and the third suction cup 5 are all located on the same arc surface. The vacuum part 6 is arranged on the frame 1, and the output end of the vacuum part 6 is respectively connected to the input end of the first suction cup 3, the second suction cup 4 and the third suction cup 5. The control unit is electrically connected to the vacuum part 6.

[0032] A lifting plate 2 is arranged on the frame 1, and the lifting plate 2 is connected to the external crane. A first suction cup 3, a second suction cup 4 and a third suction cup 5 are arranged at the lower end of the frame 1. The second suction cup 4 and the third suction cup 5 are arranged on both sides of the first chassis, respectively, and the second suction cup 4 and the third suction cup 5 are rotatably connected to the frame 1. The vacuum part 6 is used to provide adsorption force for the three suction cups. By arranging the second suction cup 4 and the third suction cup 5 to be rotatably connected, the size of the arc surface formed by the adsorption surface of the first suction cup 3, the second suction cup 4 and the third suction cup 5 can be adjusted, so that the suction cup machine can adapt to more pipe segments with outer arc surface sizes, solving the problem of only being able to adapt to pipe segments with a single outer arc surface size. At the same time, the device has a simple structure, low manufacturing cost, stable turning, and reliable suction and lifting. The use of three suction cups and two different adsorption methods allows the device to grab pipe segments of different sizes. When grabbing small pipe segments, only one suction cup works, which reduces power consumption and saves costs.

[0033] Specifically, see Figure 3 , the lower end of the frame 1 is provided with a first connecting part 7 and a second connecting part 8. The first connecting part 7 includes a first connecting rod 701 and a first connecting chain 702. The first ends of the first connecting rod 701 and the first connecting chain 702 are both connected to the frame 1, and the first connecting chain 702 is located on the second side of the first connecting rod 701. The second end of the first connecting rod 701 is rotatably connected to the second suction cup 4, the second end of the first connecting chain 702 is movably connected to the second suction cup 4, and the connection between the second suction cup 4 and the first connecting chain 702 can move up and down along the first connecting chain 702. The second connecting part 8 includes a second connecting rod and a second connecting chain. The first ends of the second connecting rod and the second connecting chain are both connected to the frame 1, and the second connecting chain is located on the first side of the second connecting rod. The second end of the second connecting rod is rotatably connected to the third suction cup 5, the second end of the second connecting chain is movably connected to the third suction cup 5, and the connection between the third suction cup 5 and the second connecting chain can move up and down along the second connecting chain.

[0034] Specifically, see Figure 2 , the vacuum part 6 includes a vacuum pump 601, an accumulator 602, a pressure sensor 603, a first vacuum solenoid valve 604, and a second vacuum solenoid valve 605. The output end of the vacuum pump 601 is connected to the input end of the accumulator 602 by pipeline. The output end of the accumulator 602 is connected to the first vacuum solenoid valve 604 and the second vacuum solenoid valve 605 by pipeline respectively. The first vacuum solenoid valve 604 is connected to the first suction cup 3 by pipeline. The second vacuum solenoid valve 605 is connected to the second suction cup 4 and the third suction cup 5 by pipeline respectively. The pressure sensor 603 is arranged on the accumulator 602. The control unit is electrically connected to the pressure sensor 603, the first vacuum solenoid valve 604, and the second vacuum solenoid valve 605 respectively.

[0035] Furthermore, the vacuum part 6 further includes a first filter 606, a second filter 607 and a third filter 608. The first filter 606 is provided on the pipeline connecting the vacuum pump 601 and the accumulator 602. The second filter 607 is provided on the pipeline connecting the first vacuum solenoid valve 604 and the first suction cup 3. The third filter 608 is provided on the pipeline connecting the second vacuum solenoid valve 605 and the second suction cup 4 and the third suction cup 5.

[0036] Preferably, it also includes a travel switch, which is arranged on the lifting plate 2 and is electrically connected to the control unit.

[0037] Furthermore, a prompt unit is included. The prompt unit is arranged on the frame 1 and is electrically connected to the control unit. The prompt unit can directly and clearly inform the operator of the current state of the device.

[0038] Further, see Figure 3 , and also includes a pipe segment identification switch 9. The pipe segment identification switch 9 is arranged at the second suction cup 4.

[0039] Furthermore, an operation panel is included, and the operation panel is communicatively connected with the control unit.

[0040] Furthermore, handles are provided on the non-adsorption surfaces of the second suction cup 4 and the third suction cup 5 .

[0041] When the vacuum pump 601 is turned on, a vacuum with a certain negative pressure is generated in the accumulator 602, and the vacuum degree of the predetermined pressure is maintained through the one-way valve arranged between the vacuum pump 601 and the accumulator 602. When the vacuum degree is greater than 80%, the control unit sends a signal to turn on the blue indicator light of the prompt unit arranged on the frame 1, and the grabbing operation can be performed at this time; if the vacuum degree is less than 80%, the operation panel fails and the grabbing operation cannot be performed.

[0042] When grabbing a small tube piece, the first vacuum solenoid valve 604 is connected, and the closed cavity formed between the first suction cup 3 and the small tube piece is instantly connected to the vacuum, and the small tube piece is immediately grasped; when dropping, the first vacuum solenoid valve 604 is disconnected, the first suction cup 3 is connected to the outside air, and the workpiece is released.

[0043] When grabbing a large pipe segment, the second vacuum solenoid valve 605 is connected, and the closed cavity formed between the second suction cup 4 and the third suction cup 5 and the large pipe segment is instantly connected to the vacuum, and the large pipe segment is immediately grasped; when blanking, the second vacuum solenoid valve 605 is disconnected, the second suction cup 4 and the third suction cup 5 are connected to the outside air, and the workpiece is released.

[0044] When the vacuum solenoid valve is disconnected, the communication between the accumulator 602 and the suction cup is cut off, and the vacuum in the accumulator 602 can be used for the next grab. In case of power failure, the solenoid valve will not change the valve core position, which will prevent the load from falling.

[0045] When the vacuum degree does not reach 80%, the red light of the prompt unit will light up and a buzzer will sound. When the vacuum degree reaches 80%, the red light will go out and the green light will light up, indicating that the grabbing action can be performed and the suction cup will be placed on the pipe segment. When grabbing a small pipe segment, the top rod of the pipe segment identification switch 9 is in the ejection state, then the second vacuum solenoid valve 605 does not work, at this time only the first suction cup 3 works, and the second suction cup 4 and the third suction cup 5 do not work; when grabbing a large pipe segment, the top rod of the pipe segment identification switch 9 is compressed, and both vacuum solenoid valves work. At this time, all three suction cups work to adsorb the large pipe segment. Press the grab button on the operation panel. After 5 seconds, the blue light of the prompt unit will light up and an alarm will sound, indicating that the pipe segment is firmly grasped and the next step can be performed.

[0046] The following is a further description of the operating steps of the adjustable pipe segment suction cup machine:

[0047] S1: Power on. Connect the device to the main power supply through the cable, and the red light of the prompt unit will light up and buzzer will sound;

[0048] S2: Start the vacuum pump 601. Turn the switch of the vacuum pump 601 on the operation panel to the "on" position; if the rotation direction of the vacuum pump 601 is correct, the vacuum degree displayed on the vacuum gauge on it will rise and the pump will make regular sounds. On the contrary, if the rotation direction of the vacuum pump 601 is incorrect, the vacuum degree of the vacuum gauge will not rise and the pump will make a chaotic sound.

[0049] When the vacuum degree does not reach 80%, the red light of the prompt unit will light up and a buzzer will sound. When the vacuum degree reaches 80%, the red light will go out and the green light will light up, indicating that the grasping action can be performed and the suction cup can be placed on the pipe piece.

[0050] S3: Grab the pipe segment. When grabbing a small pipe segment, turn the selection knob on the operation panel to the "1" position; when grabbing a large pipe segment, turn the selection knob on the operation panel to the "1+2" ​​position. When the red light of the prompt unit goes out and the green light comes on, it indicates that the lifting action is to be performed. At this time, the crane lifts the adjustable pipe segment suction cup machine. After lifting, the lifting plate 2 moves up, and the travel switch on the lifting plate 2 is turned on. Then the operation panel is invalid to prevent misoperation caused by accidental touch.

[0051] S4: Unloading. After the crane reaches the designated position, it moves downward, the lifting plate 2 contacts the travel switch to reset it, and the function of the operation panel is restored. When the pipe segment is placed correctly, press the two release buttons on the operation unit at the same time to unload the workpiece.

[0052] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.
