Description

Technical Field

[0001] This utility model relates to the field of transfer machine technology, and in particular to a transfer lifting mechanism. Background Technology

[0002] Transfer machines, as key equipment in automated logistics systems and production lines, are widely used in ports, warehouses, and various production workshops. Their main function is to transfer and connect materials between multiple parallel conveyor lines or different workstations. A typical transfer machine consists of a frame, a traveling mechanism, a carrying platform, and a transmission system. Through reciprocating or continuous motion, it performs lateral transfer tasks for pallets, boxes, and other items, effectively connecting material flow between different process segments and improving the automation level and operational efficiency of the entire logistics system.

[0003] However, in practical applications, due to the diversity of production line layouts or differences in upstream and downstream equipment models, the heights of the connecting conveyor belts are often not the same. This requires the transfer machine to have the ability to adjust its own height in order to accurately match the interface of different conveyor belts, thereby achieving stable and impact-free material transfer. However, most existing transfer machines usually have a fixed body height and can only be adapted to a certain type of conveyor belt. They lack effective height adjustment methods. When it is necessary to match with conveyor belts of different heights, it is often necessary to use cumbersome methods such as raising the entire equipment or adjusting the foundation height of the connecting conveyor belt. This is not only inconvenient to operate and has poor adaptability, but also seriously affects the flexibility of production line layout and the convenience of transformation and upgrading.

[0004] Therefore, how to provide a transfer lifting mechanism is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a transfer and lifting mechanism, which solves the problems mentioned in the background section.

[0006] A transfer and lifting mechanism according to an embodiment of the present utility model includes a body and a base plate. A telescopic member is provided on the top of the base plate, and the top end of the telescopic member is fixedly connected to the bottom of the body. A mounting frame is provided on the top of the base plate, and a rotating adjustment member is rotatably connected to the top of the mounting frame. The rotating adjustment member is movably sleeved on the surface of the telescopic member, and a drive member for controlling the adjustment of the rotating adjustment member is fixedly installed inside the mounting frame.

[0007] The telescopic components are in two sets. Each set of telescopic components includes two fixed cylinders, two telescopic rods, and a driving rod. The two fixed cylinders are fixedly installed on the top of the base plate near the outermost position. The telescopic rods are movably connected inside the fixed cylinders. The top of the telescopic rods extends to the top of the fixed cylinders and is fixedly connected to the lower surface of the machine body. The two ends of the driving rods are fixedly connected to the opposite surfaces of the two telescopic rods.

[0008] The rotating adjustment component includes two sets of rotating shafts, two sets of worm gears, and two sets of rotating rods. The rotating shafts are rotatably connected to the top of the mounting bracket, the worm gears are fixedly sleeved on the surface of the rotating shafts, and the rotating rods are fixedly connected to both ends of the rotating shafts.

[0009] The rotary adjustment component also includes a plug groove, which is located at the end of the rotating rod away from the rotating axis. The rotating rod is movably inserted into the surface of the driving rod through the plug groove.

[0010] The driving component includes a drive motor and a worm gear. The drive motor is fixedly installed inside the mounting bracket, and the worm gear is fixedly connected to the output shaft end of the drive motor. The worm gear meshes with two sets of worm wheels. The two sets of rotating shafts, the two sets of worm wheels, the two sets of rotating rods, and the insertion slot are arranged symmetrically about the worm gear as the axis of symmetry.

[0011] The fixed cylinder has a through hole on its side. A pawl is rotatably connected to the side of the fixed cylinder at the position corresponding to the through groove. A row of ratchet grooves is opened on the surface of the telescopic rod at the position corresponding to the pawl. The pawl is movably engaged in the inside of the row of ratchet grooves. A spring is fixedly connected to the side of the pawl near the fixed cylinder. The other end of the spring is movably connected to the side of the fixed cylinder.

[0012] The number of pawls is four, with two pawls forming a group, and a connecting rod is fixedly connected to the opposite face of the two pawls.

[0013] A flexible metal plate is fixedly connected to the surface of the fixed cylinder at the position corresponding to the tail end of the pawl, and a toothed block is fixedly connected to the side of the flexible metal plate at the position corresponding to the pawl. The toothed block is movably connected to the surface of the pawl.

[0014] The beneficial effects of this utility model are: This transfer and lifting mechanism achieves smooth lifting and precise position adjustment of the machine body through the coordinated design of telescopic and rotary adjustment components, improving work efficiency and stability. It adopts a worm gear and worm wheel transmission method with a self-locking function, which effectively prevents the mechanism from moving backward under load, enhancing safety and reliability. It can be precisely adjusted for conveyor belts of different heights, thereby achieving stable and impact-free material transfer.

[0015] The telescopic rod is automatically locked by the cooperation of the pawl and the row of ratchet grooves under the action of the spring, which prevents accidental retraction and ensures that the machine body remains in a fixed position during the lifting process. The overall structure is compact and easy to operate, and it is suitable for a variety of industrial transfer scenarios, reducing maintenance costs and usage risks. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] refer to Figure 1-5In this embodiment, the device includes a body 1 and a base plate 2. The top of the base plate 2 is provided with a telescopic component 3. The top of the telescopic component 3 is fixedly connected to the bottom of the body 1. There are two sets of telescopic components 3. Each set of telescopic components 3 includes two fixed cylinders 6, two telescopic rods 7 and a driving rod 8. The two fixed cylinders 6 are fixedly installed on the top of the base plate 2 near the outermost position. The telescopic rods 7 are movably connected inside the fixed cylinders 6. The top of the telescopic rods 7 extends to the top of the fixed cylinders 6 and is fixedly connected to the lower surface of the body 1. The two ends of the driving rod 8 are fixedly connected to the opposite surfaces of the two telescopic rods 7.

[0024] In specific implementation, the body 1 here refers to the transplanter body 1, which is existing technology and will not be described in detail here. The fixed cylinder 6 is used to limit the telescopic rod 7, so that the telescopic rod 7 can move up and down stably within the fixed cylinder 6, thereby effectively controlling the height of the body 1 to match different conveyor belt heights and facilitate production line adaptation. The driving rod 8 is used to stably drive the two sets of telescopic rods 7 to move up and down synchronously.

[0025] refer to Figure 1-5 In this embodiment, a mounting frame 4 is provided on the top of the base plate 2. A rotating adjustment component 5 is rotatably connected to the top of the mounting frame 4. The rotating adjustment component 5 is movably sleeved on the surface of the telescopic component 3. The rotating adjustment component 5 includes two sets of rotating shafts 9, two sets of worm gears 10 and two sets of rotating rods 11. The rotating shafts 9 are rotatably connected to the top of the mounting frame 4. The worm gears 10 are fixedly sleeved on the surface of the rotating shafts 9. The rotating rods 11 are fixedly connected to both ends of the rotating shafts 9.

[0026] In specific implementation, the mounting bracket 4 is used to stabilize the rotating shaft 9. The rotating shaft 9 is rotatably connected to the mounting bracket 4 through bearings. When the worm gear 14 rotates, it will synchronously drive the two sets of worm wheels 10 to rotate. The rotation of the two sets of worm wheels 10 drives the two sets of rotating shafts 9 to rotate. The rotation of the two sets of rotating shafts 9 drives the two sets of rotating rods 11 to rotate, so that the two sets of rotating rods 11 move closer or further away from each other. In this way, the rotation of the two sets of rotating rods 11 will drive the rod 8 to move up and down through the insertion slot 12.

[0027] refer to Figure 1-5 In this embodiment, the rotating adjustment component 5 also includes a plug groove 12, which is opened at the end of the rotating rod 11 away from the rotating shaft 9. The rotating rod 11 is movably plugged into the surface of the driving rod 8 through the plug groove 12.

[0028] In practice, the insertion slot 12 is used to insert into the surface of the drive rod 8 to facilitate the control of the up and down movement of the drive rod 8.

[0029] refer to Figure 1-5In this embodiment, a drive component for controlling the adjustment of the rotation adjustment component 5 is fixedly installed inside the mounting frame 4. The drive component includes a drive motor 13 and a worm gear 14. The drive motor 13 is fixedly installed inside the mounting frame 4, and the worm gear 14 is fixedly connected to the output shaft end of the drive motor 13. The worm gear 14 meshes with two sets of worm wheels 10. The two sets of rotating shafts 9, the two sets of worm wheels 10, the two sets of rotating rods 11, and the insertion slot 12 are arranged symmetrically about the worm gear 14 as the axis of symmetry.

[0030] In practice, the drive motor 13 is a geared motor, powered by the municipal power supply system, and its start and stop operations are controlled by a switch. This is existing technology and will not be elaborated here. When the drive motor 13 starts, it will drive the worm gear 14 to rotate. When the drive motor 13 stops, the worm gear 14 will stop rotating.

[0031] refer to Figure 1-5 In this embodiment, the side of the fixed cylinder 6 is provided with a through hole 15, and a pawl 16 is rotatably connected to the side of the fixed cylinder 6 corresponding to the position of the through groove. The surface of the telescopic rod 7 is provided with a row of ratchet grooves 17 corresponding to the position of the pawl 16. The pawl 16 is movably engaged inside the row of ratchet grooves 17. A spring member 18 is fixedly connected to the side of the pawl 16 near the fixed cylinder 6. The other end of the spring member 18 is movably connected to the side of the fixed cylinder 6. There are four pawls 16, and every two pawls 16 form a group. A connecting rod 19 is fixedly connected to the opposite face of the two pawls 16.

[0032] In specific implementation, the through hole 15 is used to place the pawl 16 so that the pawl 16 engages with the row of ratchet grooves 17, and the elastic force of the spring member 18 is used to push the pawl 16 to rotate so that the pawl 16 is stably engaged with the row of ratchet grooves 17.

[0033] refer to Figure 1-5 In this embodiment, a flexible metal plate 20 is fixedly connected to the surface of the fixed cylinder 6 at the position corresponding to the tail end of the pawl 16, and a toothed block 21 is fixedly connected to the side of the flexible metal plate 20 at the position corresponding to the pawl 16. The toothed block 21 is movably connected to the surface of the pawl 16.

[0034] In specific implementation, the flexible metal plate 20 is elastic and bends when the toothed block 21 is squeezed. The toothed block 21 is used to position the pawl 16, so that the pawl 16 is initially positioned after separating from the row of ratchet grooves 17. When the pawl 16 is engaged with the row of ratchet grooves 17 again, the toothed block 21 separates from the pawl 16.

[0035] The working principle of this utility model is as follows: When the drive motor 13 starts, the worm gear 14 rotates and drives the two sets of worm wheels 10 meshing with it to rotate, thereby driving the rotating shaft 9 to rotate. The rotating shaft 9 drives the rotating rod 11 to move. Since the rotating rod 11 is movably inserted into the surface of the driving rod 8 through the insertion slot 12, the rotation of the rotating rod 11 is converted into the vertical linear motion of the driving rod 8, pushing or pulling the telescopic rod 7 to extend and retract within the fixed cylinder 6, thereby realizing the lifting and lowering of the machine body 1. During the upward movement of the telescopic rod 7, the pawl 16 automatically engages with the row of ratchet grooves 17 on the telescopic rod 7 under the action of the spring 18, preventing the telescopic rod 7 from accidentally retracting and ensuring the stability of the machine body 1. When reverse adjustment is required... When the mechanism is in operation, first push the connecting rod 19 to drive a set of pawls 16 to move synchronously. This causes the pawls 16 to rotate and separate from the connecting ratchet grooves 17, while simultaneously squeezing the toothed block 21. The toothed block 21 then positions the rotated pawls 16 to prevent them from automatically re-engaging with the connecting ratchet grooves 17. Then, drive the motor 13 to reverse, and the worm gear 14 and worm wheel 10 provide smooth control. When the height of the machine body 1 reaches the appropriate height, pull the connecting rod 19 to separate it from the toothed block 21. At this time, the spring force of the spring element 18 pushes the pawls 16 to engage with the connecting ratchet grooves 17 to stabilize the height of the telescopic rod 7, thus achieving a safe and reliable lifting operation.

[0036] 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.
