Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically a blocking mechanism for a wheeled conveyor. Background Technology

[0002] A conveyor is a mechanical device used for the continuous transport of materials and is widely used in industry, logistics, agriculture and other fields. Conveyors can not only transport bulk materials, but also transport packaged materials. However, depending on the location of use, working environment and the type of materials being transported, there will be significant differences in their design and application.

[0003] Regarding the above and existing related technologies: conveyors are important cargo transportation equipment, among which wheeled conveyors are also common. Wheeled conveyors are generally used in unloading situations to unload goods from trucks. Since most conveyors lack a rotating mechanism, goods tend to move around on the conveyor, and at high speeds, they are prone to falling to the ground. Therefore, a blocking mechanism for wheeled conveyors is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The blocking mechanism for a wheeled conveyor of this utility model includes two support plates and multiple limiting devices. Multiple wheel sets are rotatably connected to the inner surfaces of the two support plates, and multiple insert rods are threadedly connected to the inner walls of the two support plates. The multiple limiting devices are respectively arranged on the side walls of the two support plates. Each limiting device includes a support frame, and the side walls of the support frame and the support plates are fixedly connected. A threaded rod is threadedly connected to the inner wall of the support frame. A placement plate is rotatably connected to the side wall of the threaded rod. Multiple guide wheels are rotatably connected to the surface of the placement plate. After the guide wheels move to a suitable position, they stop rotating the threaded rod. When the goods move, the goods will move on the side walls of the guide wheels, and the guide wheels will rotate on the surface of the placement plate. By setting the support frame, threaded rod, placement plate and guide wheels, the goods can be guided and the position of the goods can be limited.

[0006] Preferably, three limiting discs are fixedly connected to the surface of the placement plate. The limiting discs are located between two guide wheels. When the guide wheels rotate, the guide wheels rotate on the surface of the limiting discs, and the limiting discs can restrict the position of the two guide wheels.

[0007] Preferably, a sliding rod is fixedly connected to the side wall of the placement plate, the surface of the sliding rod is slidably connected to the inner wall of the support frame, and a limit block is fixedly connected to the end of the sliding rod away from the placement plate. When the sliding rod slides, it will drive the limit block to move. The sliding rod can limit the angle of the placement plate and also support the placement plate.

[0008] Preferably, a threaded hole is provided on the surface of the support frame near the threaded rod, and the inner wall of the threaded hole of the support frame is threadedly connected to the surface of the threaded rod. When the threaded rod rotates, the threaded rod rotates on the inner wall of the threaded hole, and the threaded hole facilitates the rotation of the threaded rod.

[0009] Preferably, a sliding hole is provided on the surface of the support frame near the sliding rod. The inner wall of the sliding hole of the support frame is slidably connected to the surface of the sliding rod. When the sliding rod slides, the sliding rod slides on the inner wall of the sliding hole. The opening of the sliding hole facilitates the movement of the sliding rod.

[0010] Preferably, the surfaces of the two support plates are provided with two adjustment devices. Each adjustment device includes two connecting blocks. The upper surfaces of the two connecting blocks are respectively fixedly connected to the bottom ends of the two support plates. An adjustment rod is rotatably connected inside the connecting block. A sleeve rod is threadedly connected to the surface of the adjustment rod. The adjustment rod can move up and down. When the adjustment rod moves, it will rotate on the inner wall of the connecting block. The connecting block will lift the support plate. By setting the connecting block, adjustment rod and sleeve rod, the support plate can be tilted easily, thereby facilitating the movement of goods.

[0011] Preferably, multiple connecting rods are fixedly connected to the surfaces of both sleeve rods, and locating pins are threadedly connected to the inner walls of the two closely spaced connecting rods. By rotating the locating pins to the inner walls of the two connecting rods, the two sleeve rods can be connected together by setting the connecting rods and locating pins, thereby increasing the strength of the entire device.

[0012] The advantages of this utility model are:

[0013] 1. When the entire device is in use, this utility model rotates the threaded rod, causing it to rotate within the threaded hole of the support frame and the side wall of the placement plate. The threaded rod drives the placement plate and guide wheel to move, and the placement plate also drives the sliding rod to slide. The sliding rod slides within the sliding hole and drives the limiting block to move. The limiting block moves within the side wall of the support frame. After the placement plate moves to the appropriate position, the threaded rod stops rotating. When the goods move, they move within the side wall of the guide wheel, and the guide wheel rotates within the surface of the limiting plate and the surface of the placement plate. By setting up the entire device, the goods can be blocked, reducing the chance of the goods falling off the wheel assembly and being damaged. At the same time, the position of the guide wheel can be adjusted according to the specifications of the goods.

[0014] 2. In this utility model, when the two support plates are fixed together, the two connecting rods will fit together. Then, the positioning pin is rotated to the inner wall of the two connecting rods. When there is a height difference in the unloading terrain, the adjusting rod is rotated to make the adjusting rod rotate on the inner wall of the sleeve rod. The adjusting rod drives the connecting block to move in height. After the support plate is tilted to a suitable angle, the adjusting rod is stopped. By setting the entire device, the tilt of the support plate can be adjusted to adapt to different terrains. Attached Figure Description

The multiple limiting devices 4 are respectively disposed on the side walls of the two support plates 1. Each limiting device 4 includes a support frame 41, the side wall of which is fixedly connected to the side wall of the support plate 1. A threaded rod 42 is threadedly connected to the inner wall of the support frame 41, and a placement plate 43 is rotatably connected to the side wall of the threaded rod 42. The surface of the support frame 41 is rotatably connected to multiple guide wheels 44. During operation, the threaded rod 42 is rotated to rotate on the inner wall of the support frame 41 and the side wall of the placement plate 43. The threaded rod 42 drives the placement plate 43 to move, and the placement plate 43 drives the guide wheels 44 to move. After the guide wheels 44 move to the appropriate position, the threaded rod 42 stops rotating. When the goods are moving, the goods will move on the side wall of the guide wheels 44, and the guide wheels 44 will rotate on the surface of the placement plate 43. By setting up the support frame 41, the threaded rod 42, the placement plate 43 and the guide wheels 44, the goods can be guided and the position of the goods can be restricted.

[0024] Three limiting discs 45 are fixedly connected to the surface of the placement plate 43. The limiting discs 45 are located between two guide wheels 44. During operation, the guide wheels 44 rotate on the surface of the limiting discs 45, and the limiting discs 45 can restrict the position of the two guide wheels 44.

[0025] A sliding rod 46 is fixedly connected to the side wall of the placement plate 43. The surface of the sliding rod 46 is slidably connected to the inner wall of the support frame 41. A limit block 47 is fixedly connected to the end of the sliding rod 46 away from the placement plate 43. During operation, the placement plate 43 drives the sliding rod 46 to slide. The sliding rod 46 slides on the inner wall of the support frame 41. When the sliding rod 46 slides, it will drive the limit block 47 to move. The sliding rod 46 can limit the angle of the placement plate 43 and also support the placement plate 43.

[0026] A threaded hole 48 is provided on the surface of the support frame 41 near the threaded rod 42. The inner wall of the threaded hole 48 of the support frame 41 is threadedly connected to the surface of the threaded rod 42. During operation, the threaded rod 42 rotates within the inner wall of the threaded hole 48. The threaded hole 48 facilitates the rotation of the threaded rod 42.

[0027] A sliding hole 49 is provided on the surface of the support frame 41 near the slide rod 46. The inner wall of the sliding hole 49 of the support frame 41 is slidably connected to the surface of the slide rod 46. During operation, the slide rod 46 slides on the inner wall of the sliding hole 49. The opening of the sliding hole 49 facilitates the movement of the slide rod 46.

[0028] Two adjustment devices 5 are provided on the surfaces of the two support plates 1. Each adjustment device 5 includes two connecting blocks 51. The upper surfaces of the two connecting blocks 51 are fixedly connected to the bottom ends of the two support plates 1 respectively. An adjustment rod 52 is rotatably connected inside the connecting block 51. A sleeve rod 53 is threadedly connected to the surface of the adjustment rod 52. During operation, rotating the adjustment rod 52 causes it to rotate on the inner wall of the sleeve rod 53, and the adjustment rod 52 will move up and down. When the adjustment rod 52 moves, it will rotate on the inner wall of the connecting block 51, and the connecting block 51 will lift the support plate 1. By setting the connecting block 51, the adjustment rod 52 and the sleeve rod 53, the support plate 1 can be tilted easily, thereby facilitating the movement of goods.

[0029] Multiple connecting rods 54 are fixedly connected to the surfaces of the two sleeve rods 53. The inner walls of the two closely spaced connecting rods 54 are threaded with positioning pins 55. During operation, the two connecting rods 54 will fit together, and the positioning pins 55 will be rotated to the inner walls of the two connecting rods 54. By setting the connecting rods 54 and positioning pins 55, the two sleeve rods 53 can be connected together, thereby increasing the strength of the entire device.

[0030] Working principle: When the entire device is needed, rotating the threaded rod 42 causes it to rotate within the threaded hole 48 of the support frame 41 and the side wall of the placement plate 43. The threaded rod 42 drives the placement plate 43 and guide wheel 44 to move. The placement plate 43 also drives the sliding rod 46 to slide, which slides within the sliding hole 49. The sliding rod 46 drives the limiting block 47 to move, which moves against the side wall of the support frame 41. After the placement plate 43 moves to the appropriate position, rotating the threaded rod 42 stops. When the goods move, they move against the side wall of the guide wheel 44, which rotates on the surface of the limiting plate 45 and the surface of the placement plate 43. This is achieved by setting the entire device... The device can block the cargo, reducing the chance of the cargo falling off the wheel set 2 and being damaged. It can also adjust the position of the guide wheel 44 according to the cargo specifications. When the two support plates 1 are fixed together, the two connecting rods 54 will fit together. Then, the positioning pin 55 is rotated to the inner wall of the two connecting rods 54. When there is a height difference in the unloading terrain, the adjusting rod 52 is rotated to make the adjusting rod 52 rotate on the inner wall of the sleeve rod 53. The adjusting rod 52 drives the connecting block 51 to move in height. After the support plate 1 is tilted to a suitable angle, the adjusting rod 52 is stopped. By setting the entire device, the tilt of the support plate 1 can be adjusted to adapt to different terrains.
