Description

Technical Field

[0001] The present invention relates to the technical field of AGV transport vehicles, in particular to an AGV intelligent transport vehicle with an anti-collision structure. Background Art

[0002] AGV is the abbreviation of automatic transport vehicle, which is an important part of intelligent logistics. It can realize the automated transportation, automatic sorting, transportation and storage of goods. The AGV cart can carry 1.5 tons of goods, which improves work efficiency and reduces the risk factor of manual handling. As a kind of automatic transport vehicle, the forklift truck has a liftable fork beam on the front side of the truck to facilitate the removal of goods.

[0003] However, in the prior art, the end of the movable beam of the AGV intelligent transport vehicle has no protective structure at all, and the movable beam usually needs to protrude a certain distance from the equipment, which makes it easy for the end of the movable beam to collide during the movement of the transport vehicle or the retrieval of goods, causing damage to the movable beam or material falling.

[0004] At the same time, the AGV intelligent transporter in the prior art directly adopts a fixed shelf structure, and because the weight of the shelf is usually large, the connection between the fixed shelf and the movable beam in the transporter is relatively good. However, when the movable beam collides, the vibration generated by the movable beam will be directly transmitted to the fixed shelf, which can easily cause the goods to move and collide.

[0005] Finally, in the prior art AGV intelligent transporter, the installation process of the shelf and the movable beam is usually carried out by moving the movable beam to the bottom of the shelf, and then moving upward to lift the shelf and take it away. However, in this process, there is no specific connection structure between the shelf and the movable beam, which makes it easy for the shelf and the movable beam that only rely on overlap connection to have unstable connection and shelf movement when they are collided. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that the end of the movable beam that exists in the background has no protective structure at all and protrudes a certain distance from the equipment, which makes the end of the movable beam prone to collision, causing damage to the movable beam or material falling; when the movable beam collides, the vibration generated by the movable beam will be directly transmitted to the fixed shelf, which is easy to cause the goods to move and collide; and the shelf and the movable beam that are only connected by overlap are prone to unstable connection when collided, causing the shelf to move.

[0010] Preferably, fixed beams are fixedly connected to both sides below the front end of the transport vehicle, and a maintenance handle is installed at the center of the upper end of the transport vehicle.

[0011] Preferably, active rollers are installed on both sides of the lower part of the transport vehicle, and the lower part of the fixed beam is movably connected to a driven roller.

[0012] Preferably, the anti-collision structure includes a protective frame, a spring 1, a slide bar 1, a support bracket, a slide bar 2, an energized iron core, a connecting rod, a support foot, a connecting bracket, a double-hole sleeve block, a spring 2 and a slider;

[0013] The cam is connected with the support frame by the spring, and the two ends of the spring are connected with each other with a spring, and the two ends of the spring are connected with each other with a spring.

[0014] Preferably, the axial position of the energized iron core is consistent with the axial position of the upper inner hole of the double-hole sleeve block, and the energized iron core can form a plug-in structure with the upper inner hole of the double-hole sleeve block.

[0015] Preferably, the outer walls of the ends of the connecting brackets are fixedly connected to the movable beams by bolts.

[0016] Preferably, the support structure includes elastic rubber columns, angle tubes, an upper frame, a lower frame, a base plate, a shelf, a side plate and a notch groove;

[0018] The AGV intelligent transport vehicle with an anti-collision structure proposed by the present invention has the following beneficial effects:

[0019] Through the coordination among the movable beam, the protective frame, the double-hole slider, the energized iron core, the spring one and the spring two, when the end of the movable beam collides, the impact force first acts on the protective frame, and the position between the protective frame and the movable beam changes, thereby causing the spring one and the spring two to deform to different degrees. During this period, the spring one absorbs the impact force in the vertical direction, and the spring two absorbs the impact force of the lateral movement. As the spring one and the spring two are constantly deformed and reset, the impact force is greatly reduced. In addition, during the continuous reset process, a magnetic field repulsion is generated between the double-hole slider made of a magnet structure on the upper layer and the energized iron core. In other words, the closer the two are to each other, the stronger the resistance is, which acts as a damping effect in the spring reset process. In this way, the problem of easy collision at the end of the movable beam causing damage to the movable beam or material falling is effectively avoided.

[0020] Through the coordination among the shelves, movable beams, lower frames, upper frames and elastic rubber columns, in this case, the goods are placed on the upper frames and supported by multiple upper frames. When the lower frame shakes with the movable beams, the anti-vibration platform composed of the lower frame, upper frame and elastic rubber columns can effectively offset the vibration transmitted to the goods. Moreover, due to the close support of multiple upper frames, even if there is a local failure, the overall stable support can be guaranteed, which effectively avoids the problem that when the movable beam collides, the vibration generated by the movable beam is directly transmitted to the fixed shelf, causing the goods to move and collide.

[0021] Through the cooperation among the double-axis motor, the second threaded rod, the conical block and the notch groove, after lifting the shelf, the user can control the double-axis motor to start, so that the double-axis motor can drive the second threaded rod on both sides to rotate, and then the conical block can move outward and insert into the inside of the notch groove until the conical block and the notch groove are tightly abutted. Since the lower part of the conical block adopts an inclined slope, the conical block can move outward and press the shelf tightly against the surface of the movable beam through the notch groove. In this way, the problem of unstable connection between the shelf and the movable beam and the movement of the shelf when impacted can be effectively avoided. BRIEF DESCRIPTION OF THE DRAWINGS

The end of the lower surface of the conical block 407 is processed with an inclined slope. The outer walls of the conical block 407 are slidably connected to the movable beam 404 on both sides through slide rails 409.

[0035] See attached Figure 1-9 : In this embodiment, the anti-collision structure 6 includes a protective frame 601, a spring 1 602, a slide bar 1 603, a support bracket 604, a slide bar 2 605, an energized iron core 606, a connecting rod 607, a supporting foot 608, a connecting bracket 609, a double-hole sleeve block 610, a spring 2 611 and a slider 612;

[0036] A plurality of support brackets 604 are respectively located at the right end of the movable beam 404 on the front and rear sides, one side of the outer wall of the support bracket 604 is fixedly connected to the movable beam 404 through a connecting bracket 609, the elastic coefficients of the spring 1 602 and the spring 2 611 can be determined according to the specific usage conditions, the inner walls of the ends of the support brackets 604 are slidably connected with a slider 612, the inner side of the slider 612 is fixedly connected with a slider 2 605, the inner wall of the support bracket 604 is fixedly connected with a slider 1 603, the outer wall of the slider 1 603 is slidably connected with a double-hole sleeve block 610 on both sides, the lower hole of the double-hole sleeve block 610 is slidably connected to the slider 1 603, the upper hole of the double-hole sleeve block 610 is a magnet structure, the outer wall of the slider 2 605 is slidably connected with a support foot 608 on both sides, the end of the support foot 608 They are all fixedly connected to the protective frame 601, the two ends of spring one 602 are respectively fixedly connected to the double-hole sleeve blocks 610 on both sides, and the outer walls of the double-hole sleeve blocks 610 are rotatably connected to the support feet 608 through connecting rods 607 and pin shafts, the two ends of spring two 611 are respectively fixedly connected to the support feet 608 and the support bracket 604, and the outer sides of the double-hole sleeve blocks 610 are provided with energized iron cores 606, and multiple energized iron cores 606 are respectively fixedly connected to the upper and lower sides of the end of the outer wall of the support bracket 604, the axial position of the energized iron core 606 is consistent with the axial position of the upper inner hole of the double-hole sleeve block 610, and the energized iron core 606 can form a plug-in structure with the upper inner hole of the double-hole sleeve block 610, and the end outer wall of the connecting bracket 609 is fixedly connected to the movable beam 404 by bolts 12.

[0037] Through the cooperation among the movable beam 404, the protective frame 601, the double-hole slider 610, the energized iron core 606, the spring 1 603 and the spring 2 611, when a collision occurs at the end of the movable beam 404, the impact force first acts on the protective frame 601, and a position change occurs between the protective frame 601 and the movable beam 404, thereby causing the spring 1 603 and the spring 2 611 to deform to varying degrees. During this period, the spring 1 603 absorbs the impact force in the vertical direction, and the spring 2 611 absorbs the impact force of the lateral movement. As the spring 1 603 and the spring 2 611 are constantly deformed and reset, the impact force is greatly reduced. In the process of continuous reset, a magnetic field repulsion is generated between the double-hole slider 610 made of a magnet structure on the upper layer and the energized iron core 606. In other words, the closer the two are to each other, the stronger the resistance is, which acts as a damping effect in the spring reset process. In this way, the problem of the movable beam being damaged or the material falling due to the easy collision at the end of the movable beam is effectively avoided.

[0038] See attached Figure 1-9 : In this embodiment, the support structure 5 includes an elastic rubber column 501, a corner tube 502, an upper frame 503, a lower frame 504, a base plate 505, a shelf 506, a side plate 507 and a notch groove 508;

[0039] The shelf 506 is placed on the outer wall of the movable beam 404, and a plurality of side panels 507 are fixedly connected to the four corners of the lower end of the shelf 506. The elastic rubber column 501 has good elasticity. The inner wall of the side panel 507 is in contact with the movable beam 404. The central inner wall of the side panel 507 is processed with a notch groove 508. The side panel 507 is used for accurate placement of the shelf 506 and the movable beam 404, and the inner wall of the notch groove 508 is in contact with the conical block 407. A plurality of base plates 505 are equidistantly embedded and installed on the upper surface of the shelf 506. The upper ends of the base plates 505 are fixedly connected to the lower frame 504. The upper frame 503 is arranged above the lower frame 504. The inner four corners of the lower frame 504 and the upper frame 503 are fixedly connected to the corner tubes 502, and the upper and lower corner tubes 502 are connected by the elastic rubber column 501.

[0040] Through the cooperation among the shelf 506, the movable beam 404, the lower frame 504, the upper frame 503 and the elastic rubber column 501, in this case, the goods are placed on the upper frame 503 and supported by multiple upper frames 503. When the lower frame 504 shakes with the movable beam 404, the shockproof platform composed of the lower frame 504, the upper frame 503 and the elastic rubber column 501 can effectively offset the vibration transmitted to the goods. In addition, since multiple upper frames 503 are supported in a close contact manner, the overall stable support can be guaranteed even if a local failure occurs, which effectively avoids the problem that when the movable beam collides, the vibration generated by the movable beam is transmitted to the fixed shelf, causing the goods to move and collide.

[0041] Through the cooperation between the double-axis motor 408, the second threaded rod 410, the conical block 407 and the notched groove 508, after lifting the shelf 506, the user can control the double-axis motor 408 to start, so that the double-axis motor 408 can drive the second threaded rod 410 on both sides to rotate, and then the conical block 407 can move outward and insert into the notched groove 508 until the conical block 407 and the notched groove 508 are tightly abutted. Since the lower part of the conical block 407 adopts an inclined slope, the conical block 407 can move outward to press the shelf 506 tightly against the surface of the movable beam 404 through the notched groove 508. In this way, the problem of unstable connection between the shelf and the movable beam and the movement of the shelf when impacted is effectively avoided.

[0042] Working principle:

[0043] When the AGV intelligent transporter with an anti-collision structure is needed, first, the user controls the active roller 10 at the transporter 1 to rotate, so that the equipment moves to the corresponding shelf position. When picking up materials, the bottom of the shelf 506 in this case is suspended by the shelf support, which can provide enough space for the movable beam 404 and the anti-collision structure 6 to extend into the lower part of the shelf 506. Then, the power motor 405 is controlled to drive the threaded rod 402 to rotate through the output gear set 406, and then the threaded rod 402 drives the sliding platform 401 and the movable beam 404 to move upward to complete the picking of materials from the shelf 506. Finally, the active roller 10 at the transporter 1 is controlled to rotate, so that the equipment carries the materials and moves them to the required position. In this way, the conventional use requirements of the AGV intelligent transporter are met.

[0044] However, compared with the AGV intelligent transport vehicle in the prior art, the end of its movable beam has no protective structure at all, and the movable beam usually needs to protrude from the equipment for a certain distance, which makes it easy for the end of the movable beam to collide during the movement of the transport vehicle or the retrieval of goods, causing damage to the movable beam or material falling. Therefore, the present invention designs an anti-collision structure 6, so that when a collision occurs at the end of the movable beam 404, the impact force first acts on the protective frame 601, and a position change occurs between the protective frame 601 and the movable beam 404, thereby causing different degrees of spring 1 603 and spring 2 611. During the deformation, spring 1 603 absorbs the impact force in the vertical direction, and spring 2 611 absorbs the impact force of the lateral movement. As spring 1 603 and spring 2 611 are continuously deformed and reset, the impact force is greatly reduced. In the process of continuous reset, a magnetic field repulsion is generated between the double-hole slider 610 made of a magnet structure on the upper layer and the energized iron core 606. In other words, the closer the two are to each other, the stronger the resistance is, which acts as a damping effect in the spring reset process. In this way, it is effectively avoided that the end of the movable beam is prone to collision, causing damage to the movable beam or material falling.

[0045] At the same time, compared with the AGV intelligent transporter in the prior art, it directly adopts a fixed shelf structure, and because the weight of the shelf is usually large, the connection between the fixed shelf and the movable beam in the transporter is better. However, when the movable beam collides, the vibration generated by the movable beam will be directly transmitted to the fixed shelf, which is easy to cause the goods to move and collide. Therefore, the present case designs a support structure 5, so that in this case, the goods are placed above the upper frame 503 and supported by multiple upper frames 503. When the lower frame 504 shakes with the movable beam 404, the shockproof platform composed of the lower frame 504, the upper frame 503 and the elastic rubber column 501 can effectively offset the vibration transmitted to the goods, and because the multiple upper frames 503 are supported in a close connection, even if local failure occurs, the overall stable support can be guaranteed, which effectively avoids the problem that when the movable beam collides, the vibration generated by the movable beam is directly transmitted to the fixed shelf, causing the goods to move and collide.

[0046] Finally, compared with the AGV intelligent transporter in the prior art, the installation process of the shelf and the movable beam is usually carried out by moving the movable beam to the bottom of the shelf, and then moving upward to lift the shelf and take it away. However, there is no specific connection structure between the shelf and the movable beam in this process, which makes it easy for the shelf and the movable beam that only rely on overlap connection to be unstable when they are hit, causing the shelf to move. Therefore, this case designs a dual-axis motor 408, a threaded rod 410, a conical block 407 and a notch groove 508, so that when the shelf 506 is lifted up, the movable beam can be easily moved. After that, the user can control the double-axis motor 408 to start, so that the double-axis motor 408 can drive the threaded rods 410 on both sides to rotate, and then the conical block 407 can move outward and insert into the notch groove 508 until the conical block 407 and the notch groove 508 are tightly abutted. Since the lower part of the conical block 407 adopts an inclined slope, the conical block 407 can move outward and press the shelf 506 tightly against the surface of the movable beam 404 through the notch groove 508. In this way, the problem of unstable connection between the shelf and the movable beam and the movement of the shelf when impacted is effectively avoided.
