Description

Technical Field

[0001] This utility model relates to the field of handling device technology, and in particular to a multi-station load handling device. Background Technology

[0002] In today's industrial production and construction fields, it is often necessary to move various heavy objects, such as stone blocks and large castings. When these heavy objects are used in industrial production and construction operations, it is inevitable that they need to be moved. Traditional methods of moving these objects mostly involve manual handling or using cranes and electric hoists for lifting.

[0003] While manual handling offers advantages in flexibility, it is inefficient for handling heavy objects or large castings, involves high labor intensity for workers, and is difficult to meet the needs of large-scale, high-intensity handling operations. Furthermore, it is prone to accidents due to physical exhaustion during handling, posing significant safety hazards. Although hoisting can move heavier objects, it has stringent requirements for the working environment, requiring sufficient open space to set up the hoisting equipment. In narrow construction spaces or densely packed industrial workshops, cranes are often difficult to operate, making it impossible to efficiently and quickly move or transfer heavy objects.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Example, refer to Figures 1-7 A multi-station load handling device includes a chassis 1;

[0033] The chassis 1 is equipped with a walking mechanism 2 at both ends of the top length direction on both sides, and the overall handling device is moved by the walking mechanism 2.

[0034] The top plate 3 is fixedly installed above the chassis 1. A rotating platform 4 is installed on one side of the end face of the top plate 3, and multiple load stations 9 are provided on the other side. The load stations 9 are used to carry heavy objects such as stone blocks for transporting stone blocks.

[0035] A rotating platform 4 is driven and connected to a fixed plate 5. A lifting mechanism 6 is fixedly installed on the top of the fixed plate 5. A load transfer frame 7 is driven and connected to the side of the lifting mechanism 6 near the load station 9. A clamping drive motor 8 is installed on the load transfer frame 7. The clamping drive motor 8 drives and connects to a clamping mechanism 10. The clamping mechanism 10 is located above the load station 9. In use, the rotating platform 4 drives the lifting mechanism 6 to rotate the clamping drive motor 8 and the clamping mechanism 10 installed on the load transfer frame 7. When the load transfer frame 7 rotates away from the load station 9, the lifting mechanism 6 drives the load transfer frame 7 to descend and approach the heavy object to be transported. After the clamping drive motor 8 drives the clamping mechanism 10 to clamp and fix the heavy object, the lifting mechanism 6 drives the load transfer frame 7 to rise and lift the heavy object. The rotating platform 4 rotates and moves the load transfer frame 7 to directly above the load station 9. The lifting mechanism 6 drives the load transfer frame 7 to descend again. After descending to the bottom, the clamping drive motor 8 drives the clamping mechanism 10 to release the heavy object into the load station 9. There are multiple load stations 9, which can simultaneously carry multiple heavy objects for centralized transportation.

[0036] Furthermore, a number of support columns 101 are provided between the chassis 1 and the top plate 3. During use, the two ends of the support columns 101 are connected to the chassis 1 and the top plate 3 respectively by bolts to stabilize and support the top plate 3, so that a certain space is maintained between the top plate 3 and the chassis 1, and the load on the top plate 3 is transferred to the chassis 1, ensuring that the entire handling device has a high load capacity and remains stable during movement.

[0037] Furthermore, the walking mechanism 2 includes a walking drive motor 201, the output end of which is connected to a walking wheel 202. There is a space between the chassis 1 and the top plate 3 for mounting and fixing the walking drive motor 201. The output end of the walking drive motor 201 extends outward toward the chassis 1 and is connected to the walking wheel 202 for supporting and carrying heavy objects and transferring heavy objects under the drive of the walking drive motor 201.

[0038] Specifically, the preferred model of the walking drive motor 201 is ACM130-24-1500. This model of walking drive motor 201 has high torque, which can meet the power requirements of high load when transferring and transporting heavy objects, and has a high walking speed. At the same time, it is small in size, which makes it easy to install in the limited space between the chassis 1 and the top plate 3.

[0039] Furthermore, the rotating platform 4 includes a rotary drive motor 401 fixedly installed at the bottom of the top plate 3. The output end of the rotary drive motor 401 passes through the top plate 3 and drives a rotary flange 402. The rotary flange 402 is connected to the fixed plate 5 by bolts. A fixed frame 501 is installed on the fixed plate 5, and a lifting mechanism 6 is installed on the fixed frame 501. In use, the rotary drive motor 401 is installed at the bottom of the top plate 3, and its output end passes through the top plate 3 to drive the rotary flange 402, thereby driving the rotary flange 402 to rotate. This causes the rotary flange 402 to drive the fixed plate 5 and the lifting mechanism 6 connected to the fixed plate 5 to rotate, thereby realizing the angle conversion between the lifting mechanism 6 and the clamping mechanism 10 at multiple load positions 9 and the heavy object placement position. This allows the clamping mechanism 10 to accurately reach the heavy object to be transported and accurately place the heavy object on any load position 9.

[0040] Specifically, the preferred model of the rotary drive motor 401 is ACSM100-48-1000, which can precisely control the position and rotational angular velocity when the rotary platform 4 rotates. Moreover, this type of rotary drive motor 401 can still maintain a high torque output at low speeds, ensuring that the rotary platform 4 has better stability when driving the load to rotate.

[0041] Furthermore, the lifting mechanism 6 includes two sets of longitudinally arranged guide rails 602 fixedly installed on both sides of the front end of the fixed frame 501, and a lifting drive motor 601. A support beam 603 is installed between the top ends of the two sets of guide rails 602. A driven pulley 604 is rotatably connected inside the support beam 603. The lifting drive motor 601 is installed at the rear end of the fixed frame 501, and its output end passes through the fixed frame 501 and drives a drive pulley 605. A synchronous belt 606 is tensioned between the drive pulley 605 and the driven pulley 604. A drive block 607 is installed on the 06. The other end of the drive block 607 is connected to the load transfer frame 7 by bolts. In use, the lifting drive motor 601 drives the drive pulley 605 to rotate. The drive pulley 605 drives the driven pulley 604 to rotate through the synchronous belt 606. The drive block 607 on the synchronous belt 606 moves with the synchronous belt 606, thereby driving the load transfer frame 7 to move up and down along the guide rail 602, so that the clamping mechanism 10 can approach or move away from the heavy object, realizing the lifting and lowering of the heavy object.

[0042] Specifically, the preferred model of the lifting drive motor 601 is 5IK120RGU-C. This type of lifting drive motor 601 is a servo motor with high control precision and response speed. It can achieve precise lifting control, meet the requirements of the lifting mechanism 6 for precise lifting and lowering of heavy objects, and can withstand a certain degree of impact load to ensure operational stability during the handling of heavy objects.

[0043] Furthermore, the load transfer frame 7 includes a side plate 701. A guide slider 702 is installed on one end face of the side plate 701 and is slidably connected to two sets of guide rails 602 respectively. A first load plate 703 is connected to the top of the side plate 701 and a second load plate 704 is connected to the bottom. The first load plate 703 and the second load plate 704 are parallel to each other and both extend outward away from the lifting mechanism 6. In use, the guide slider 702 on the side plate 701 is slidably connected to the guide rail 602 to ensure that the load transfer frame 7 slides along the guide rail 602 during the lifting process.

[0044] Furthermore, the bottom of the first load plate 703 is fixedly connected to the clamping drive motor 8, and the clamping mechanism 10 is installed on the second load plate 704. The output end of the clamping drive motor 8 drives the clamping mechanism 10. In use, the first load plate 703 and the second load plate 704 are used to install the clamping drive motor 8 and the clamping mechanism 10 respectively, providing stable support.

[0045] Specifically, the preferred model of the clamping drive motor 8 is ACSM100-48-1000. This type of motor can accurately control the position and rotational angular velocity and has a high torque output, thereby accurately controlling the opening and closing angle of the clamping mechanism 10 for accurately picking up or putting down heavy objects.

[0046] Furthermore, the clamping mechanism 10 includes two sets of mirror-arranged drive arms 1001. Each set of drive arms 1001 has a gear 1002 at its end and a gripper 1003 extending outward from its other end. The two sets of gears 1002 mesh with each other. The output end of the clamping drive motor 8 is connected to one of the gears 1002. In use, the clamping drive motor 8 drives one of the gears 1002 to rotate. The meshing gears 1002 drive the two sets of drive arms 1001 to move, causing the gripper 1003 to open or close for picking up or releasing heavy objects.

[0047] Furthermore, one end of the gripper 1003 is connected to the drive arm 1001 by bolts, and the other end is provided with a semi-circular gripping ring 10031. In use, the gripping ring 10031 is used to adapt to the arc-shaped contour of the heavy object. The two gripping rings 10031 approach each other and close under the drive of the gripping drive motor 8, thereby gripping and picking up the heavy object.

[0048] Furthermore, multiple load stations 9 are concentric with the rotating platform 4 and are distributed at equal arcs on the side of the top plate 3 away from the rotating platform 4, so that the clamping mechanism 10 can be driven by the rotating platform 4 to move directly above any load station 9, making it convenient to pick up or place heavy objects, and without causing interference between the other load stations 9.

[0049] Working principle: When heavy objects such as stone blocks need to be moved, the rotary drive motor 401 starts, driving the rotary flange 402 to rotate. This causes the fixed plate 5 connected to the rotary flange 402, as well as the lifting mechanism 6, load transfer frame 7, clamping drive motor 8, and clamping mechanism 10 mounted on the fixed plate 5, to rotate as a whole. The rotation moves to the side away from the load position 9, directly above the location of the stone block. The lifting drive motor 601 then drives the drive pulley 605 to rotate. The drive pulley 605 drives the driven pulley 604 to rotate via the synchronous belt 606. The drive block 607 on the synchronous belt 606 rotates accordingly. The stepper belt 606 moves, thereby driving the load transfer frame 7 to descend along the guide rail 602, bringing the clamping mechanism 10 closer to the stone block. When the load transfer frame 7 descends to the appropriate position, the clamping drive motor 8 starts, and its output end is connected to one of the gears 1002, driving the two sets of mirror-mounted drive arms 1001 to move. The grippers 1003 at the drive end drive the clamping rings 10031 to open. After picking up the stone block, the two clamping rings 10031 move closer to each other and close under the drive of the clamping drive motor 8, thereby clamping and fixing the stone block. The lifting mechanism 6 then drives the load transfer frame again. 7. The lifting mechanism raises the stone block to a certain height. Then, the rotating platform 4 rotates in the opposite direction, moving the load transfer frame 7 directly above the load station 9. Multiple load stations 9 are concentric with the rotating platform 4 and are distributed at equal arcs on the side of the top plate 3 away from the rotating platform 4. This allows the clamping mechanism 10 to move precisely above any load station 9 under the drive of the rotating platform 4. The lifting mechanism 6 drives the load transfer frame 7 to descend. After descending to the correct position, the clamping drive motor 8 drives the clamping mechanism 10 in the opposite direction, causing the two sets of drive arms 1001 to open the grippers 1003, releasing the stone block onto the load station 9. In the process, there are multiple load stations 9, which can simultaneously carry multiple stone blocks for centralized transportation, greatly improving the transportation efficiency. After completing the transportation of one stone block, the device can continue to repeat the above process to transport more stone blocks to other idle load stations 9. When it is necessary to transfer the stone block, the walking drive motor 201 on the chassis 1 is started, and its output end drives the walking wheel 202 to rotate, so that the entire transportation device moves to the target position. Then, through the coordinated action of the rotating platform 4, the lifting mechanism 6 and the clamping mechanism 10, the stone block is taken out from the load station 9 and placed in the designated position.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
