[0002] Roller conveyors are suitable for conveying items with flat or near-flat bottoms. They mainly consist of drive rollers, frames, supports, and drive units. They feature large conveying capacity, high speed, smooth operation, and the ability to transport multiple product types on a single line. Roller conveyors are easily connected and filtered together, and multiple roller lines, along with other conveying equipment or specialized machines, can form complex logistics conveying systems.

[0003] For example, Chinese patent CN212291532U discloses a roller conveyor, including a conveyor frame. The conveyor frame is composed of multiple vertical leg supports, multiple horizontal leg supports, multiple foot plates, multiple adjustable foot plates, and multiple body legs. Body profiles are symmetrically arranged on both sides of the upper end face of the conveyor frame. The symmetrically arranged body profiles are equipped with upper cover plates and end cover plates. Multiple drive rollers, roller support seats, and roller support seat cover plates are arranged on the upper end face of the conveyor frame. One end of the drive roller is connected to the drive chain inside the body profile. Material is placed on the drive roller. A rotating motor is arranged at the lower end of the body profile. A motor protective cover is also provided on the outside of the rotating motor. By setting up drive rollers, the design time of the roller conveyor is shortened.

[0004] However, when processing metal or other large or heavy workpieces, the device is prone to instability and falling during lifting due to the inertia of the conveyor. Utility Model Content

[0005] The purpose of this invention is to provide a floor-mounted lifting conveyor that can limit the movement of items during lifting to ensure stability.

[0006] The technical solution adopted by this utility model to solve the above problems is: a floor-mounted lifting conveyor, comprising:

[0007] The system includes a base plate, with two lifting frames fixedly connected to the top of the base plate. Each lifting frame has an L-shaped plate fixedly connected to one side. A worm gear is installed inside one of the L-shaped plates, with a drive motor connected to one end of the worm gear. Multiple worm wheels are connected to the surface of the worm gear, and a rotating rod is connected through the axis of each worm wheel. One end of the rotating rod is rotatably connected to the surface of the L-shaped plate without the worm gear. A conveying roller is sleeved on the surface of the rotating rod. A lifting assembly is installed between the two lifting frames.

[0008] A further preferred technical solution is as follows: the lifting assembly includes a lifting plate, two lifting screws disposed inside the lifting plate, pulleys fixedly connected to the top of the two lifting screws, a synchronous belt drivingly connected between the two pulleys, a lifting motor connected to the bottom end of one of the lifting screws, two abutment plates slidably connected to the top of the lifting plate, a threaded cylinder fixedly connected to the surface of the abutment plates, and a threaded rod threadedly connected inside the threaded cylinder; a conveying component is installed inside the lifting plate, and blocking components are installed on both sides of the lifting plate.

[0009] A further preferred technical solution is that the blocking assembly includes a vertical plate fixedly connected to one side of the lifting plate, a baffle slidably connected inside the vertical plate, a lifting cylinder fixedly connected to the bottom of the baffle, an adjusting screw threadedly connected inside the lifting cylinder, a bottom end of the adjusting screw rotatably connected to the bottom of the vertical plate, a first helical gear sleeved on the surface of the adjusting screw, a second helical gear meshing with the first helical gear, a connecting gear sleeved on the intermediate shaft of the second helical gear, two lifting gear plates meshing with both sides of the connecting gear, a vertical rod fixedly connected to the surface of the lifting gear plate, and a connecting block fixedly connected to the end of the vertical rod.

[0010] A further preferred technical solution is that a protective cover is fixedly connected to the surface of the vertical plate, and vertical grooves are provided on both sides of the inner wall of the protective cover, with one side of the lifting toothed plate slidably disposed inside the vertical groove.

[0011] A further preferred technical solution is that a spring rod is fixedly connected to the top of the connecting block, and the top end of the spring rod is fixedly connected to the bottom of the protective cover.

[0012] A further preferred technical solution is that a seated bearing is installed on the surface of the threaded rod, and the bottom of the seated bearing is fixedly connected to the top of the lifting plate.

[0013] A further preferred technical solution is that a horizontal plate is fixedly connected inside the lifting frame, and the bottom of the lifting plate abuts against the top of the horizontal plate.

[0014] A further preferred technical solution is that: two locking blocks are fixedly connected to the bottom of the abutment plate, and the top of the lifting plate is provided with a locking groove that cooperates with the locking blocks.

[0015] A further preferred technical solution is that: the bottom of the connecting block abuts against a fixing plate, and the two ends of the fixing plate are respectively fixedly connected to the surfaces of the two lifting frames.

[0016] A further preferred technical solution is that: a rotating bearing is installed on the surface of the lifting screw, the bottom of the rotating bearing is installed on the top of the lifting frame, and the bottom end of the lifting screw that is not connected to the lifting motor is rotatably connected to the top of the base plate.

[0017] In summary, this utility model has the following advantages:

[0018] 1. This utility model, by setting up a blocking component, activates the lifting motor when an item enters the lifting plate. Under the action of the synchronous belt and pulley, the two lifting screws rotate simultaneously, conveying the lifting plate upward. During this process, the connecting block gradually disengages from the fixed plate. Under the action of the spring rod, the lifting gear plate is reset, and the connecting gear rotates due to the meshing action of the lifting gear plate. This causes the second helical gear to rotate through the first helical gear, driving the adjusting screw to rotate, thereby causing the lifting cylinder to move upward with the baffle, achieving automatic blocking on both sides of the item and reducing the possibility of the item falling out of the lifting plate.

[0019] 2. By setting up abutment plates, after the item is moved to the lifting plate, rotating the threaded rod causes the threaded cylinder to rotate, thereby causing the abutment plates to move towards the surface of the item. By rotating the two threaded rods, the two abutment plates are driven to clamp and fix the surface of the item, ensuring the stability of the item during the lifting and moving process, reducing the possibility of collision due to inertia, and improving the stability of the device.

One end of the rotating rod is rotatably connected to the front of the back L-shaped plate 3. A conveying roller 6 is sleeved on the surface of the rotating rod.

[0029] A lifting assembly is installed between the two lifting frames 2. This assembly is used to transport items to a higher position. The lifting assembly includes a lifting plate 7. A horizontal plate is fixedly connected inside the lifting frame 2. The bottom of the lifting plate 7 abuts against the top of the horizontal plate, facilitating limiting and supporting the lifting plate 7. Two lifting screws 8 are threadedly connected inside the lifting plate 7. Rotary bearings are installed on the surface of the lifting screws 8, with their bottoms mounted on the top of the lifting frame 2. The bottom end of the rear lifting screw 8 is rotatably connected to the top of the base plate 1, ensuring normal rotation of the lifting screws 8. Pulleys are fixedly connected to the tops of the two lifting screws 8, and the two pulleys are connected by a synchronous belt drive. (Front lifting...) A lifting motor is fixedly connected to the bottom end of the lead screw 8. Two abutment plates 9 are slidably connected to the top of the lifting plate 7. Two locking blocks are fixedly connected to the bottom of the abutment plates 9. The top of the lifting plate 7 has a locking groove that matches the locking blocks, ensuring the normal operation of the abutment plates 9. A threaded cylinder 10 is fixedly connected to the surface of the abutment plates 9. A threaded rod 11 is threadedly connected inside the threaded cylinder 10. A seated bearing is installed on the surface of the threaded rod 11. The bottom of the seated bearing is fixedly connected to the top of the lifting plate 7, ensuring the normal operation of the threaded rod 11. A conveying component is installed inside the lifting plate 7. Blocking components are installed on both sides of the lifting plate 7 to facilitate clamping and fixing of items.

[0030] The blocking assembly is used to block items from both sides, reducing the possibility of items falling. The blocking assembly includes a vertical plate 12 fixedly connected to one side of the lifting plate 7. A baffle 13 is slidably connected inside the vertical plate 12. A lifting cylinder 14 is fixedly connected to the bottom of the baffle 13. An adjusting screw 15 is threadedly connected inside the lifting cylinder 14. The bottom end of the adjusting screw 15 is rotatably connected to the bottom of the inner wall of the vertical plate 12. A first helical gear 16 is sleeved on the surface of the adjusting screw 15. A second helical gear 17 is meshed on the surface of the first helical gear 16. A connecting gear 18 is sleeved on the surface of the intermediate shaft of the second helical gear 17. Two lifting gear plates 19 are meshed on the surface of the connecting gear 18. A protective cover is fixedly connected to the surface. Vertical grooves are provided on both sides of the inner wall of the protective cover. One side of the lifting tooth plate 19 is slidably set inside the vertical groove to ensure the normal operation of the lifting tooth plate 19. A vertical rod 20 is fixedly connected to the surface of the lifting tooth plate 19. A connecting block 21 is fixedly connected to one end of the vertical rod 20 to facilitate blocking and limiting the object and prevent the object from falling. A spring rod is fixedly connected to the top of the bottom connecting block 21. The top of the spring rod is fixedly connected to the bottom of the protective cover to facilitate the repositioning of the lifting tooth plate 19. A fixing plate abuts against the bottom of the connecting block 21. The two sides of the fixing plate are fixedly connected to the surfaces of the two lifting frames 2 to facilitate the limiting and abutting of the connecting block 21.

[0031] The implementation principle of a floor-mounted lifting conveyor in this application embodiment is as follows: the item is placed on the conveying roller 6, the drive motor is started, so that the worm 4 drives the worm wheel 5 to rotate, and then the conveying roller 6 conveys the item to the lifting plate 7 on the left.

[0032] When an item enters the lifting plate 7, the lifting motor is started. Under the action of the synchronous belt and pulley, the two lifting screws 8 rotate simultaneously, conveying the lifting plate 7 upward. During this process, the connecting block 21 gradually disengages from the fixed plate. Under the action of the spring rod, the lifting tooth plate 19 is reset. The connecting gear 18 rotates due to the meshing action of the lifting tooth plate 19, thereby causing the second helical gear 17 to rotate through the first helical gear 16, which in turn causes the adjusting screw 15 to rotate. This causes the lifting cylinder 14 to move upward with the baffle 13, achieving automatic blocking on both sides of the item and reducing the possibility of the item falling out of the lifting plate 7.

[0033] After the item is transported to the work position, the user presses the upper connecting block 21 with his hand. Under the action of the vertical rod 20, the lifting gear plate 19 moves vertically, which causes the connecting gear 18 to rotate in the opposite direction. Under the action of the first helical gear 16, the second helical gear 17, the adjusting screw 15 and the lifting cylinder 14, the baffle 13 moves into the interior of the vertical plate 12, making it easier to remove the item.

[0034] After the item is moved onto the lifting plate 7, the threaded rod 11 is rotated to make the threaded cylinder 10 rotate, which in turn makes the abutment plate 9 move toward the surface of the item. By rotating the two threaded rods 11, the two abutment plates 9 are driven to clamp and fix the surface of the item, ensuring the stability of the item during the lifting and moving process, reducing the collision of the item due to inertia, and improving the stability of the device.
