Description

Technical Field

[0001] This utility model relates to the field of grab bucket technology, specifically a three-axis grab bucket with high and low point recognition. Background Technology

[0002] A grab bucket is a specialized tool used by cranes to grab dry bulk cargo. It consists of two or more closable bucket-shaped jaw plates that come together to form a cargo space. During loading, the jaw plates close in the material pile, and the material is grabbed into the cargo space. During unloading, the jaw plates open while suspended above the material pile, and the material scatters onto the pile. The opening and closing of the jaw plates is generally controlled by the crane's hoisting mechanism wire rope. Existing three-axis grab buckets still have certain defects in use, such as:

[0003] Existing three-axis grab buckets have a high opening position during the unloading and grabbing process, which causes a lot of dust and puts a great burden on the environment. Most of them cannot identify the height of the material piled on the ground to confirm the unloading height. Furthermore, after long-term use, three-axis grab buckets need to be disassembled and maintained regularly, but existing three-axis grab buckets usually require the use of some tools for disassembly and assembly, which is quite troublesome.

[0029] Please see Figures 1-4 and Figure 7 This utility model provides a technical solution: a three-axis grab bucket with high and low point recognition, comprising: an I-shaped column 1, grab bucket segments 2, a hydraulic rod 3, and a ranging mechanism 4; the grab bucket segments 2 are rotatably connected to one side of the I-shaped column 1, the hydraulic rod 3 is rotatably connected to one side of the grab bucket segments 2, the hydraulic rod 3 is rotatably connected to one side of the I-shaped column 1, the ranging mechanism 4 is provided on one side of the I-shaped column 1, and a docking mechanism 5 is provided on the upper surface of the I-shaped column 1; a support tube 401, a shell 402, a rangefinder 403, a camera 404, a glass plate 405, a drive motor 406, and a brush plate 4. 07.

A support pipe 401 is connected to the upper surface of the I-shaped column 1. A housing 402 is connected to one side of the support pipe 401. A rangefinder 403 is connected to the upper inner wall of the housing 402. A camera 404 is connected to the upper inner wall of the housing 402 near the rangefinder 403. A glass plate 405 is located below the rangefinder 403 and the camera 404. A glass plate 405 is connected to the inner wall of the outer casing 402. A drive motor 406 is connected to the upper surface of the glass plate 405 via a motor mount. The output end of the drive motor 406 passes through the inner wall of the glass plate 405 and is connected to a brush plate 407. The brush plate 407 abuts against the lower part of the glass plate 405. A water tank 408 is connected to one side of the I-shaped column 1. A water pump 409 is connected to the upper surface of the water tank 408. A water pump pipe 410 is connected to one side of the water pump 409 and passes through the water tank 408. A water delivery pipe 411 is connected to the other side of the water pump 409 for water delivery. Pipe 411 is connected through the support pipe 401, and the other end of the water pipe 411 is connected to a universal gooseneck pipe 412. The universal gooseneck pipe 412 is connected through the bottom of the support pipe 401. A controller 413 is connected to the upper surface of the housing 402, and a speaker 414 is embedded on one side of the housing 402. A human infrared sensor 415 is connected to the upper inner wall of the housing 402 near the rear of the rangefinder 403 and the camera 404, and a human radar sensor 416 is connected to the upper inner wall of the housing 402 near the front of the rangefinder 403 and the camera 404.

[0030] In practice, a rangefinder 403 is used to detect the distance to the material, a camera 404 is used to observe and identify the high and low points of the material or the ground, and a human infrared sensor 415 and a human radar sensor 416 are used to detect whether there are pedestrians. When impurities are attached to the glass plate 405 and affect the detection, the water pump 409 is started and the washing liquid in the water tank 408 is drawn out through the water pipe 410 and sprayed onto the glass plate 405 through the universal gooseneck pipe 412 via the water pipe 411. The drive motor 406 drives the brush plate 407 to rotate and brush the glass plate 405 so that the three-axis grab bucket can identify the high and low points.

[0031] See Figures 1-3 , Figure 5 and Figure 6 It is known that the docking mechanism 5 includes: a cavity 501, a hollow T-post 502, a slot 503, a circular plate 504, a guide groove 505, an L-shaped insert rod 506, a worm gear 507, and a worm 508. The upper surface of the I-shaped post 1 has a cavity 501, and the hollow T-post 502 is slidably connected inside the cavity 501. A slot 503 is provided on one side of the cavity 501. The hollow T-post 502 has a circular plate 504 inside, and a guide groove is provided inside the circular plate 504. An L-shaped insert rod 506 is slidably connected within the groove 505 and the guide groove 505. The L-shaped insert rod 506 slides through the inner wall of the hollow T-post 502 and is engaged in the slot 503. A worm gear 507 is connected to the upper surface of the circular plate 504. The worm gear 507 is rotatably connected to the upper inner wall of the hollow T-post 502. A worm 508 is meshed with the front part of the worm gear 507 and rotates through the inner wall of the hollow T-post 502.

[0032] In practice, the grab bucket 2 is placed on the ground, and then the worm gear 508 is rotated to drive the worm wheel 507 to rotate the circular plate 504, which in turn drives the guide groove 505 inside the circular plate 504 to rotate. This pulls the L-shaped insert rod 506 out of the slot 503 and into the hollow T-post 502. Then, the hollow T-post 502 is pulled out of the insertion cavity 501 to maintain the three-axis grab bucket. Then, the insertion cavity 501 is inserted into the hollow T-post 502, and the worm gear 508 is rotated in the opposite direction to fix it, making the three-axis grab bucket easy to assemble and disassemble.

[0033] In summary: When using this three-axis grab bucket with high / low point recognition, firstly, the hollow T-column 502 is bolted to the crane's robotic arm. Then, the controller 413 is connected to the control system in the crane cab. The hydraulic rod 3 is then shortened, pulling the three sets of grab bucket petals 2 to rotate and open, inserting them onto the material. The hydraulic rod 3 is then extended to allow the three sets of grab bucket petals 2 to grab the material. The crane's robotic arm is then moved to the desired material placement position. The rangefinder 403 detects the ground level and the height of the stacked material. Once the set height is reached, the hydraulic rod 3 is shortened again. The pressure rod 3 rotates and opens the three sets of grab buckets 2 to lower the material. When impurities obstruct the view, the water pump 409 is started to spray washing liquid. Then, the drive motor 406 is started to rotate the brush plate 407 to brush the glass plate 405. The human infrared sensor 415 emits infrared light and the human radar sensor 416 emits sound waves to detect pedestrians. If a pedestrian approaches, the speaker 414 sounds an alarm, causing the hydraulic rod 3 to stop suddenly. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
